The correct diagnosis is adolescent posttraumatic stress disorder (PTSD), as the patient's symptoms — recurrent nightmares, flashbacks, hypervigilance, and avoidance behaviors — are closely linked to her recent traumatic experience, fitting the clinical profile of PTSD. The MRI finding, although abnormal, does not correlate with a neurologic cause for her symptoms and may be incidental.

Temporal lobe epilepsy can cause behavioral changes but does not explain the specific PTSD symptoms like flashbacks and nightmares. 

Chronic migraine could explain the headaches but not the full spectrum of PTSD symptoms. 

Major depressive disorder could account for some of the emotional and social symptoms but lacks the characteristic re-experiencing and avoidance behaviors typical of PTSD.

Adolescent PTSD is a significant public health concern, causing significant distress to a small portion of the youth population. By late adolescence, approximately two thirds of youths have been exposed to trauma, and 8% of these individuals meet the criteria for PTSD by age 18. The incidence is exceptionally high in cases of sexual abuse and assault, with rates reaching up to 40%. PTSD in adolescents is associated with severe psychological distress, reduced academic performance, and a high rate of comorbidities, including anxiety and depression. There are specific populations (including children who are evacuated from home, asylum seekers, etc.) that show higher rates of PTSD. 

PTSD can lead to chronic impairments, comorbid psychiatric disorders, and an increased risk for suicide, with cases documented in toddlers as young as 1 year old. Thus, it is important to consider the individual's background and social history, as older children with PTSD may present with symptoms from early childhood trauma, often distant from the time of clinical evaluation.

Intrusion symptoms are a hallmark of PTSD, characterized by persistent and uncontrollable thoughts, dreams, and emotional reactions related to the traumatic event. These symptoms distinguish PTSD from other anxiety and mood disorders. Children with PTSD often experience involuntary, distressing thoughts and memories triggered by trauma cues, such as sights, sounds, or smells associated with the traumatic event. In younger children, these intrusive thoughts may manifest through repetitive play that re-enacts aspects of the trauma.

Nightmares are also common, although in children the content may not always directly relate to the traumatic event. Chronic nightmares contribute to sleep disturbances, exacerbating PTSD symptoms. Trauma reminders, which can be both internal (thoughts, memories) and external (places, sensory experiences), can provoke severe distress and physiologic reactions.

Avoidance symptoms often develop as a coping mechanism in response to distressing re-experiencing symptoms. Children may avoid thoughts, feelings, and memories of the traumatic event or people, places, and activities associated with the trauma. In young children, avoidance may manifest as restricted play or reduced exploration of their environment.

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR) outlines specific criteria for diagnosing PTSD in individuals over 6 years old, which includes exposure to actual or threatened death, serious injury, or sexual violence, and the presence of symptoms such as intrusion, avoidance, negative mood alterations, and heightened arousal. The DSM-5-TR provides tailored diagnostic criteria for developmental differences in symptom expression for children under 6.

Managing PTSD in children requires a patient-specific approach, with an emphasis on obtaining consent from both the patient and guardian. The American Academy of Child and Adolescent Psychiatry (AACAP) recommends psychotherapy as the first-line treatment for pediatric PTSD. However, patients with severe symptoms or comorbidities may initially be unable to engage in meaningful therapy and may require medication to stabilize symptoms before starting psychotherapy.

Trauma-focused psychotherapy, including cognitive-behavioral therapy (CBT), exposure-based therapy, and eye movement desensitization and reprocessing (EMDR) therapy, is the preferred treatment for PTSD. Clinical studies have shown that patients receiving trauma-focused psychotherapy experience more remarkable symptom improvement than those who do not receive treatment and, in children, psychotherapy generally yields better outcomes than pharmacotherapy.

While selective serotonin reuptake inhibitors like sertraline and paroxetine are FDA-approved for PTSD treatment in adults, their efficacy in children often produces outcomes similar to those of placebo. Medications are typically reserved for severe symptoms and are used as an off-label treatment in pediatric cases. Pharmacologic management may be necessary when the severity of symptoms prevents the use of trauma-focused psychotherapy or requires immediate stabilization.

Patients with primary psychiatric disorders with dermatologic manifestations often seek treatment from dermatologists instead of psychiatrists.¹ For example, patients with delusions of parasitosis may lack insight into the underlying etiology of their disease and instead fixate on establishing an organic cause for their symptoms. As a result, it is an increasingly common practice for dermatologists to diagnose and treat psychiatric conditions.¹ The goal of this study was to evaluate trends for the top 5 antipsychotics most frequently prescribed by dermatologists in the Medicare Part D database.

In this retrospective analysis, we consulted the Medicare Provider Utilization and Payment Data for January 2013 through December 2020, which is provided to the public by the Centers for Medicare & Medicaid Services.² Only prescribing data from dermatologists were included in this study by using the built-in filter on the website to select “dermatology” as the prescriber type. All other provider types were excluded. We chose the top 5 most prescribed antipsychotics based on the number of supply days reported. Supply days—defined by Medicare as the number of days’ worth of medication that is prescribed—were used as a metric for ­utilization; therefore, each drug’s total supply days prescribed by dermatologists were calculated using this combined filter of drug name and total supply days using the database.

To analyze utilization over time, the annual average growth rate (AAGR) was calculated by determining the growth rate in total supply days annually from 2013 to 2020 and then averaging those rates to determine the overall AAGR. For greater clinical relevance, we calculated the average growth in supply days for the entire study period by determining the difference in the number of supply days for each year and then averaging these values. This was done to consider overall trends across dermatology rather than individual dermatologist prescribing patterns.

Based on our analysis, the antipsychotics most frequently prescribed by dermatologists for Medicare patients from January 2013 to December 2020 were pimozide, quetiapine, risperidone, olanzapine, and aripiprazole. The AAGR for each drug was 2.35%, 4.89%, 5.59%, 9.48%, and 20.72%, respectively, which is consistent with increased utilization over the study period for all 5 drugs (Table 1). The change in cost per supply day for the same period was 1.3%, –66.1%, –60.2%, –81.7%, and –84.3%, respectively. The net difference in cost per supply day over this entire period was $0.02, –$2.79, –$1.06, –$5.37, and –$21.22, respectively (Table 2).

Obesity is a chronic disease affecting more than 20% of adults in the United States. In 2022, prevalence was 20.5% among those aged 18 to 24 and 39.9% among those aged 45 to 54 years. This patient meets criteria for obesity (BMI ≥ 30), and it is likely that her obesity contributed to development of T2D, hypertension, osteoarthritis, and joint edema (as shown in the image). 

Patients with obesity are at high risk of developing cardiometabolic disease and osteoarthritis. Obesity is a key driver of T2D and cardiovascular disease development through its influence on insulin and lipid metabolism and proinflammatory changes. Factors associated with obesity that foster arthritis development include the erosive effects of adiponectin and leptin on cartilage and direct inflammation in joint tissues. 

It is important for patients with obesity and comorbid T2D and hypertension to receive multidisciplinary care designed to address all aspects of their health and minimize their risk for progression. The primary goal for this patient should be to promote weight loss safely while also improving her glycemic control and blood pressure. For patients with obesity and comorbid T2D, the American Diabetes Association recommends glucagon-like peptide-1 receptor agonists (GLP-1 RAs; semaglutide or liraglutide) or the dual gastric inhibitory polypeptide (GIP)/GLP-1 RA tirzepatide. The GLP-1 RA drugs reduce the risk for major cardiovascular events for patients with T2D while also providing substantial reductions in glucose levels without increasing hypoglycemia risk. They are available in higher doses (semaglutide 2.4 mg weekly, liraglutide 3.0 mg daily) for patients with obesity. These drugs also have salubrious effects on cardiorenal health and reduce progression of kidney disease. Tirzepatide produced greater reductions in A1c vs semaglutide in patients with T2D in the SURPASS-2 trial. It also has been shown to reduce atherosclerotic cardiovascular events in patients with overweight or obesity (without diabetes) in a post hoc analysis of the SURMOUNT-1 trial. Its effect on a broad set of cardiac, renal, and metabolic outcomes is being studied in the ongoing SURMOUNT-MMO trial. The American Gastroenterological Association and other organizations recommend treatment with antiobesity medications along with lifestyle modifications for patients with obesity (BMI ≥ 30) and weight-related complications (BMI > 27). 

Pharmacologic interventions for osteoarthritis include nonsteroidal anti-inflammatory drugs, including ibuprofen, naproxen, meloxicam, diclofenac, or celecoxib. These may be used with regular follow-up to assess cardiovascular and gastrointestinal health. Topical nonsteroidal anti-inflammatory drugs also may be useful. For more intractable joint pain, options include injecting corticosteroid or sodium hyaluronate into the affected joints or joint replacement.

In addition, comprehensive care includes lifestyle modifications designed to promote weight loss, reduce sodium, and increase exercise and intake of healthy foods. While maintaining intensive lifestyle modifications can be challenging, achieving weight loss of ≥ 5% can improve cardiometabolic risk factors in patients with obesity and T2D. Greater benefit is seen with greater reductions in body weight. Other interventions include behavioral modification and encouragement of increased physical activity to the extent of the patient's ability. Achieving substantial weight loss also could help relieve stress on the patient's joints, improve physical function, and mitigate osteoarthritis-related pain. The patient also may benefit from nonpharmacologic approaches to joint pain, including hot or cold compresses, physical therapy, and strength and resistance training to improve the strength of muscles supporting the joints.

The latest research on therapeutic management of patients with relapsing-remitting multiple sclerosis (MS) presented at the European Committee for Treatment and Research in Multiple Sclerosis 2024 Congress is reported by Dr Patricia Coyle from Stony Brook University Hospital, in Stony Brook, New York. 

Dr Coyle first discusses a registry study looking at initiation of monoclonal antibody therapy for patients with pediatric-onset MS. Results showed a significant reduction in disability at age 23 and beyond when therapy was initiated in childhood.   

Next, Dr Coyle discusses a trial examining the safety and efficacy of frexalimab, a second-generation anti-CD40L antibody. In an open-label extension trial through 72 weeks, frexalimab provided a sustained reduction of disease activity, as measured by MRI, and was well tolerated. 

She then details a study looking at the effects of disease-modifying therapies (DMTs) on pregnancy outcomes in patients with MS. Using a German MS registry, researchers looked at 3722 pregnancies, 2885 with DMT exposure, and concluded that most pregnancy outcomes are unaffected by DMT exposure; however, the data showed the potential risk for reduced birth rates. 

Finally, Dr Coyle examines the efficacy of the Bruton tyrosine kinase (BTK) inhibitor tolebrutinib, as evidenced by the HERCULES trial and the two GEMINI trials. In HERCULES, the BTK inhibitor reduced 6-month disability progression by a significant 31% compared with placebo.

The latest research on therapeutic management of patients with relapsing-remitting multiple sclerosis (MS) presented at the European Committee for Treatment and Research in Multiple Sclerosis 2024 Congress is reported by Dr Patricia Coyle from Stony Brook University Hospital, in Stony Brook, New York. 

Dr Coyle first discusses a registry study looking at initiation of monoclonal antibody therapy for patients with pediatric-onset MS. Results showed a significant reduction in disability at age 23 and beyond when therapy was initiated in childhood.   

Next, Dr Coyle discusses a trial examining the safety and efficacy of frexalimab, a second-generation anti-CD40L antibody. In an open-label extension trial through 72 weeks, frexalimab provided a sustained reduction of disease activity, as measured by MRI, and was well tolerated. 

She then details a study looking at the effects of disease-modifying therapies (DMTs) on pregnancy outcomes in patients with MS. Using a German MS registry, researchers looked at 3722 pregnancies, 2885 with DMT exposure, and concluded that most pregnancy outcomes are unaffected by DMT exposure; however, the data showed the potential risk for reduced birth rates. 

Finally, Dr Coyle examines the efficacy of the Bruton tyrosine kinase (BTK) inhibitor tolebrutinib, as evidenced by the HERCULES trial and the two GEMINI trials. In HERCULES, the BTK inhibitor reduced 6-month disability progression by a significant 31% compared with placebo.

A previously healthy 31-year-old female active-duty Navy sailor working as a calibration technician developed a painful, erythematous, pruritic, indurated plaque on her left breast. The sailor was not lactating and had no known family history of malignancy. Initially, she was treated by her primary care practitioner for presumed mastitis with oral cephalexin and then with oral clindamycin with no symptom improvement. About 2 weeks after the completion of both antibiotic courses, she developed angioedema and periorbital edema (Figure 1), requiring highdose corticosteroids and antihistamines with a corticosteroid course of prednisone 40 mg daily tapered to 10 mg daily over 12 days and diphenhydramine 25 mg to use up to 4 times daily. Workup for both was acquired and hereditary angioedema was unremarkable. Two months later, the patient developed patches of alopecia, oral ulcerations, and hypopigmented plaques with a peripheral hyperpigmented rim on the central face and bilateral conchal bowls (Figure 2). She also developed hypopigmented papules with peripheral hyperpigmentation on the bilateral dorsal hands overlying the metacarpal and proximal interphalangeal joints, which eventually ulcerated (Figure 3). Laboratory evaluation, including tests for creatine kinase, aldolase, transaminases, lactate dehydrogenase, and autoantibodies (antiJo-1, anti-Mi-2, anti-MDA-5, anti-TIF-1, anti-NXP-2, and anti-SAEP), were unremarkable. A punch biopsy from a papule on the right dorsal hand showed superficial perivascular lymphohistiocytic inflammation with a subtle focal increase in dermal mucin, highlighted by the colloidal iron stain. Further evaluation of the left breast plaque revealed ER/PR+ HER2- stage IIIB inflammatory breast cancer.

DISCUSSION

Based on the clinical presentation and diagnosis of inflammatory breast cancer, the patient was diagnosed with paraneoplastic clinically amyopathic dermatomyositis (CADM). She was treated for her breast cancer with an initial chemotherapy regimen consisting of dose-dense cyclophosphamide and doxorubicin followed by paclitaxel. The patient underwent a mastectomy, axillary lymph node dissection, and 25 sessions of radiation therapy, and is currently continuing therapy with anastrozole 1 mg daily and ovarian suppression with leuprorelin 11.25 mg every 3 months. For the severe angioedema and dermatomyositis-like cutaneous findings, the patient was continued on high-dose corticosteroids at prednisone 60 mg daily with a prolonged taper to prednisone 10 mg daily. After about 10 months, she transitioned from prednisone 10 mg daily to hydrocortisone 30 mg daily and is currently tapering her hydrocortisone dosing. She was additionally started on monthly intravenous immunoglobulin, hydroxychloroquine 300 mg daily, and amlodipine 5 mg daily. The ulcerated papules on her hands were treated with topical clobetasol 0.05% ointment applied daily, topical tacrolimus 0.1% ointment applied daily, and multiple intralesional triamcinolone 5 mg/mL injections. With this regimen, the patient experienced significant improvement in her cutaneous symptoms.

CADM is a rare autoimmune inflammatory disease featuring classic dermatomyositis-like cutaneous findings such as a heliotrope rash and Gottron papules. Ulcerative Gottron papules are less common than the typical erythematous papules and are associated more strongly with amyopathic disease.1 Paraneoplastic myositis poses a diagnostic challenge because it presents like an idiopathic dermatomyositis and often has a heterogeneous clinical presentation with additional manifestations, including periorbital edema, myalgias, dysphagia, and shortness of breath. If clinically suspected, laboratory tests (eg, creatine kinase, aldolase, transaminases, and lactate dehydrogenase) can assist in diagnosing paraneoplastic myositis. Additionally, serologic testing for autoantibodies such as anti-CADM-140, anti-Jo-1, anti-Mi-2, antiMDA-5, anti-TIF-1, anti-NXP-2, and antiSAE can assist the diagnosis and predict disease phenotype.^1,2

Malignancy can precede, occur during, or develop after the diagnosis of CADM.³ Malignancies most often associated with CADM include ovarian, breast, and lung cancers.⁴ Despite the strong correlation with malignancy, there are currently no screening guidelines for malignancy upon inflammatory myositis diagnosis. Therefore, it is important to consider the entirety of a patient’s clinical presentation in establishing further evaluation in the initial diagnostic workup.

There are numerous systemic complications associated with inflammatory myositis and imaging modalities can help to rule out some of these conditions. CADM is strongly associated with the development of interstitial lung disease, so chest radiography and pulmonary function testing are often checked.¹ Though cardiac and esophageal involvement are more commonly associated with classic dermatomyositis, it may be useful to obtain an electrocardiogram to rule out conduction abnormalities from myocardial involvement, along with esophageal manometry to evaluate for esophageal dysmotility.^1,5

In the management of paraneoplastic CADM, the underlying malignancy should be treated first.⁶ If symptoms persist after the cancer is in remission, then CADM is treated with immunosuppressive medications such as methotrexate, mycophenolate mofetil, or azathioprine. Physical therapy can also provide further symptom relief for those suffering from proximal weakness.

CONCLUSIONS

Presumed mastitis, angioedema, and eczematous lesions for this patient were dermatologic manifestations of an underlying inflammatory breast cancer. This case highlights the importance of early recognition, the diagnosis of CADM and awareness of its association with underlying malignancy, especially within the primary care setting where most skin concerns are addressed. Early clinical suspicion and a swift diagnostic workup can further optimize multidisciplinary management, which is often required to treat malignancies.

Antimicrobial resistance is a global threat and burden to health care, with > 2.8 million antibiotic-resistant infections occurring annually in the United States.¹ To combat this issue and improve patient care, the US Department of Veterans Affairs (VA) has implemented antimicrobial stewardship programs (ASPs) across its health care systems. ASPs are multidisciplinary teams that promote evidence-based use of antimicrobials through activities supporting appropriate selection, dosing, route, and duration of antimicrobial therapy. ASP best practices are also included in the Joint Commission and Centers for Medicare and Medicaid Services accreditation standards.²

The foundational charge for VA facilities to develop and maintain ASPs was outlined in 2014 and updated in 2023 in the Veterans Health Administration (VHA) Directive 1031 on antimicrobial stewardship programs.2 This directive outlines specific requirements for all VA ASPs, including personnel, staffing levels, and the roles and responsibilities of all team members. VHA now requires that Veterans Integrated Services Networks (VISNs) establish robust ASP collaboratives. A VISN ASP collaborative consists of stewardship champions from each VA medical center in the VISN and is designed to support, develop, and enhance ASP programs across all facilities within that VISN.² Some VISNs may lack an ASP collaborative altogether, and others with existing groups may seek ways to expand their collaboratives in line with the updated directive. Prior to VHA Directive 1031, the VA Sunshine Healthcare Network (VISN 8) established an ASP collaborative. This article describes the structure and activities of the VISN 8 ASP collaborative and highlights a recent VISN 8 quality assurance initiative related to vancomycin area under the curve (AUC) dosing that illustrates how ASP collaboratives can enhance stewardship and clinical care across broad geographic areas.

VISN 8 ASP

The VHA, the largest integrated US health care system, is divided into 18 VISNs that provide regional systems of care to enhance access and meet the local health care needs of veterans.³ VISN 8 serves > 1.5 million veterans across 165,759 km² in Florida, South Georgia, Puerto Rico, and the US Virgin Islands.⁴ The network is composed of 7 health systems with 8 medical centers and > 60 outpatient clinics. These facilities provide comprehensive acute, primary, and specialty care, as well as mental health and extended care services in inpatient, outpatient, nursing home, and home care settings.⁴

The 2023 VHA Directive 1031 update recognizes the importance of VISN-level coordination of ASP activities to enhance the standardization of care and build partnerships in stewardship across all levels of care. The VISN 8 ASP collaborative workgroup (ASPWG) was established in 2015. Consistent with Directive 1031, the ASPWG is guided by clinician and pharmacist VISN leads. These leads serve as subject matter experts, facilitate access to resources, establish VISN-level consensus, and enhance communication among local ASP champions at medical centers within the VISN. All 7 health systems include = 1 ASP champion (clinician or pharmacist) in the ASPWG. Ad hoc members, whose routine duties are not solely focused on antimicrobial stewardship, contribute to specific stewardship projects as needed. For example, the ASPWG has included internal medicine, emergency department, community living center pharmacists, representatives from pharmacy administration, and trainees (pharmacy students and residents, and infectious diseases fellows) in antimicrobial stewardship initiatives. The inclusion of non-ASP champions is not discussed in VHA Directive 1031. However, these members have made valuable contributions to the ASPWG.

The ASPWG meets monthly. Agendas and priorities are developed by the VISN pharmacist and health care practitioner (HCP) leads. Monthly discussions may include but are not limited to a review of national formulary decisions, VISN goals and metrics, infectious diseases hot topics, pharmacoeconomic initiatives, strong practice presentations, regulatory and accreditation preparation, preparation of tracking reports, as well as the development of both patient-level and HCPlevel tools, resources, and education materials. This forum facilitates collaborative learning: members process and synthesize information, share and reframe ideas, and listen to other viewpoints to gain a complete understanding as a group.⁵ For example, ASPWG members have leaned on each other to prepare for Joint Commission accreditation surveys and strengthen the VISN 8 COVID-19 program through the rollout of vaccines and treatments. Other collaborative projects completed over the past few years included a penicillin allergy testing initiative and anti-methicillin-resistant Staphylococcus aureus (MRSA) and pseudomonal medication use evaluations. This team-centric problem-solving approach is highly effective while also fostering professional and social relationships. However, collaboratives could be perceived to have drawbacks. There may be opportunity costs if ASP time is allocated for issues that have already been addressed locally or concerns that standardization might hinder rapid adoption of practices at individual sites. Therefore, participation in each distinct group initiative is optional. This allows sites to choose projects related to their high priority areas and maintain bandwidth to implement practices not yet adopted by the larger group.

The ASPWG tracks metrics related to antimicrobial use with quarterly data presented by the VISN pharmacist lead. Both inpatient and outpatient metrics are evaluated, such as days of therapy per 1000 days and outpatient antibiotic prescriptions per 1000 unique patients. Facilities are benchmarked against their own historical data and other VISN sites, as well as other VISNs across the country. When outliers are identified, facilities are encouraged to conduct local projects to identify reasons for different antimicrobial use patterns and subsequent initiatives to optimize antimicrobial use. Benchmarking against VISN facilities can be useful since VISN facilities may be more similar than facilities in different geographic regions. Each year, the ASPWG reviews the current metrics, makes adjustments to address VISN priorities, and votes for approval of the metrics that will be tracked in the coming year.

Participation in an ASP collaborative streamlines the rollout of ASP and quality improvement initiatives across multiple sites, allowing ASPs to impact a greater number of veterans and evaluate initiatives on a larger scale. In 2019, with the anticipation of revised vancomycin dosing and monitoring guidelines, our ASPWG began to strategize the transition to AUC-based vancomycin monitoring.⁶ This multisite initiative showcases the strengths of implementing and evaluating practice changes as part of an ASP collaborative.

Vancomycin Dosing

The antibiotic vancomycin is used primarily for the treatment of MRSA infections.⁶ The 2020 consensus guidelines for vancomycin therapeutic monitoring recommend using the AUC to minimum inhibitory concentration (MIC) ratio as the pharmacodynamic target for serious MRSA infections, with an AUC/MIC goal of 400 to 600 mcg*h/mL.⁶ Prior guidelines recommended using vancomycin trough concentrations of 15 to 20 mcg/mL as a surrogate for this AUC target. However, subsequent studies have shown that trough-based dosing is associated with higher vancomycin exposures, supratherapeutic AUCs, and increased risk of vancomycin-associated acute kidney injury (AKI).^7,8 Therefore, more direct AUC estimation is now recommended.⁶ The preferred approach for AUC calculations is through Bayesian modeling. Due to limited resources and software availability, many facilities use an alternative method involving 2 postdistributive serum vancomycin concentrations and first-order pharmacokinetic equations. This approach can optimize vancomycin dosing but is more mathematically and logistically challenging. Transitioning from troughto AUC-based vancomycin monitoring requires careful planning and comprehensive staff education.

In 2019, the VISN 8 ASPWG created a comprehensive vancomycin AUC toolkit to facilitate implementation. Components included a pharmacokinetic management policy and procedure, a vancomycin dosing guide, a progress note template, educational materials specific to pharmacy, nursing, laboratory, and medical services, a pharmacist competency examination, and a vancomycin AUC calculator (eAppendix). Each component was developed by a subgroup with the understanding that sites could incorporate variations based on local practices and needs.

The vancomycin AUC calculator was developed to be user-friendly and included safety validation protocols to prevent the entry of erroneous data (eg, unrealistic patient weight or laboratory values). The calculator allowed users to copy data into the electronic health record to avoid manual transcription errors and improve operational efficiency. It offered suggested volume of distribution estimates and 2 methods to estimate elimination constant (Ke ) depending on the patient’s weight.^9,10 Creatinine clearance could be estimated using serum creatinine or cystatin C and considered amputation history. The default AUC goal in the calculator was 400 to 550 mcg*h/mL. This range was chosen based on consensus guidelines, data suggesting increased risk of AKI with AUCs > 515 mcg*h/mL, and the preference for conservative empiric dosing in the generally older VA population.¹¹ The calculator suggested loading doses of about 25 mg/kg with a 2500 mg limit. VHA facilities could make limited modifications to the calculator based on local policies and procedures (eg, adjusting default infusion times or a dosing intervals).

The VISN 8 Pharmacy Pharmacokinetic Dosing Manual was developed as a comprehensive document to guide pharmacy staff with dosing vancomycin across diverse patient populations. This document included recommendations for renal function assessment, patient-specific considerations when choosing an empiric vancomycin dose, methods of ordering vancomycin peak, trough, and surveillance levels, dose determination based on 2 levels, and other clinical insights or frequently asked questions.

ASPWG members presented an accredited continuing education webinar for pharmacists, which reviewed the rationale for AUC-targeted dosing, changes to the current pharmacokinetic dosing program, case-based scenarios across various patient populations, and potential challenges associated with vancomycin AUC-based dosing. A recording of the live training was also made available. A vancomycin AUC dosing competency test was developed with 11 basic pharmacokinetic and case-based questions and comprehensive explanations provided for each answer.

VHA facilities implemented AUC dosing in a staggered manner, allowing for lessons learned at earlier adopters to be addressed proactively at later sites. The dosing calculator and education documents were updated iteratively as opportunities for improvement were discovered. ASPWG members held local office hours to address questions or concerns from staff at their facilities. Sharing standardized materials across the VISN reduced individual site workload and complications in rolling out this complex new process.

VISN-WIDE QUALITY ASSURANCE

At the time of project conception, 4 of 7 VISN 8 health systems had transitioned to AUC-based dosing. A quality assurance protocol to compare patient outcomes before and after changing to AUC dosing was developed. Each site followed local protocols for project approval and data were deidentified, collected, and aggregated for analysis.

The primary objectives were to compare the incidence of AKI and persistent bacteremia and assess rates of AUC target attainment (400-600 mcg*h/mL) in the AUC-based and trough-based dosing groups.⁶ Data for both groups included anthropomorphic measurements, serum creatinine, amputation status, vancomycin dosing, and infection characteristics. The X² test was used for categorical data and the t test was used for continuous data. A 2-tailed α of 0.05 was used to determine significance. Each site sequentially reviewed all patients receiving ≥ 48 hours of intravenous vancomycin over a 3-month period and contributed up to 50 patients for each group. Due to staggered implementation, the study periods for sites spanned 2018 to 2023. A minimum 6-month washout period was observed between the trough and AUC groups at each site. Patients were excluded if pregnant, receiving renal replacement therapy, or presenting with AKI at the time of vancomycin initiation.

There were 168 patients in the AUC group and 172 patients in the trough group (Table 1). The rate of AUC target attainment with the initial dosing regimen varied across sites from 18% to 69% (mean, 48%). Total daily vancomycin exposure was lower in the AUC group compared with the trough group (2402 mg vs 2605 mg, respectively), with AUC-dosed patients being less likely to experience troughs level ≥ 15 or 20 mcg/mL (Table 2). There was a statistically significant lower rate of AKI in the AUC group: 2.4% in the AUC group (range, 2%-3%) vs 10.4% (range 7%-12%) in the trough group (P = .002). Rates of AKI were comparable to those observed in previous interventions.⁶ There was no statistical difference in length of stay, time to blood culture clearance, or rate of persistent bacteremia in the 2 groups, but these assessments were limited by sample size.

We did not anticipate such variability in initial target attainment across sites. The multisite quality assurance design allowed for qualitative evaluation of variability in dosing practices, which likely arose from sites and individual pharmacists having some flexibility in adjusting dosing tool parameters. Further analysis revealed that the facility with low initial target attainment was not routinely utilizing vancomycin loading doses. Sites routinely use robust loading doses achieved earlier and more consistent target attainment. Some sites used a narrower AUC target range in certain clinical scenarios (eg, > 500 mcg*h/mL for septic patients and < 500 mcg*h/mL for patients with less severe infections) rather than the 400 to 550 mcg*h/mL range for all patients. Sites targeting broader AUC ranges for all patients had higher rates of target attainment. Reviewing differences among sites allowed the ASPWG to identify best practices to optimize future care.

CONCLUSIONS

VHA ASPs must meet the standards outlined in VHA Directive 1031, including the new requirement for each VISN to develop an ASP collaborative. The VISN 8 ASPWG demonstrates how ASP champions can collaborate to solve common issues, complete tasks, explore new infectious diseases concepts, and impact large veteran populations. Furthermore, ASP collaboratives can harness their collective size to complete robust quality assurance evaluations that might otherwise be underpowered if completed at a single center. A limitation of the collaborative model is that a site with a robust ASP may already have specific practices in place. Expanding the ASP collaborative model further highlights the VHA role as a nationwide leader in ASP best practices.

Antimicrobial resistance is a global threat and burden to health care, with > 2.8 million antibiotic-resistant infections occurring annually in the United States.¹ To combat this issue and improve patient care, the US Department of Veterans Affairs (VA) has implemented antimicrobial stewardship programs (ASPs) across its health care systems. ASPs are multidisciplinary teams that promote evidence-based use of antimicrobials through activities supporting appropriate selection, dosing, route, and duration of antimicrobial therapy. ASP best practices are also included in the Joint Commission and Centers for Medicare and Medicaid Services accreditation standards.²

The foundational charge for VA facilities to develop and maintain ASPs was outlined in 2014 and updated in 2023 in the Veterans Health Administration (VHA) Directive 1031 on antimicrobial stewardship programs.2 This directive outlines specific requirements for all VA ASPs, including personnel, staffing levels, and the roles and responsibilities of all team members. VHA now requires that Veterans Integrated Services Networks (VISNs) establish robust ASP collaboratives. A VISN ASP collaborative consists of stewardship champions from each VA medical center in the VISN and is designed to support, develop, and enhance ASP programs across all facilities within that VISN.² Some VISNs may lack an ASP collaborative altogether, and others with existing groups may seek ways to expand their collaboratives in line with the updated directive. Prior to VHA Directive 1031, the VA Sunshine Healthcare Network (VISN 8) established an ASP collaborative. This article describes the structure and activities of the VISN 8 ASP collaborative and highlights a recent VISN 8 quality assurance initiative related to vancomycin area under the curve (AUC) dosing that illustrates how ASP collaboratives can enhance stewardship and clinical care across broad geographic areas.

VISN 8 ASP

The VHA, the largest integrated US health care system, is divided into 18 VISNs that provide regional systems of care to enhance access and meet the local health care needs of veterans.³ VISN 8 serves > 1.5 million veterans across 165,759 km² in Florida, South Georgia, Puerto Rico, and the US Virgin Islands.⁴ The network is composed of 7 health systems with 8 medical centers and > 60 outpatient clinics. These facilities provide comprehensive acute, primary, and specialty care, as well as mental health and extended care services in inpatient, outpatient, nursing home, and home care settings.⁴

The 2023 VHA Directive 1031 update recognizes the importance of VISN-level coordination of ASP activities to enhance the standardization of care and build partnerships in stewardship across all levels of care. The VISN 8 ASP collaborative workgroup (ASPWG) was established in 2015. Consistent with Directive 1031, the ASPWG is guided by clinician and pharmacist VISN leads. These leads serve as subject matter experts, facilitate access to resources, establish VISN-level consensus, and enhance communication among local ASP champions at medical centers within the VISN. All 7 health systems include = 1 ASP champion (clinician or pharmacist) in the ASPWG. Ad hoc members, whose routine duties are not solely focused on antimicrobial stewardship, contribute to specific stewardship projects as needed. For example, the ASPWG has included internal medicine, emergency department, community living center pharmacists, representatives from pharmacy administration, and trainees (pharmacy students and residents, and infectious diseases fellows) in antimicrobial stewardship initiatives. The inclusion of non-ASP champions is not discussed in VHA Directive 1031. However, these members have made valuable contributions to the ASPWG.

The ASPWG meets monthly. Agendas and priorities are developed by the VISN pharmacist and health care practitioner (HCP) leads. Monthly discussions may include but are not limited to a review of national formulary decisions, VISN goals and metrics, infectious diseases hot topics, pharmacoeconomic initiatives, strong practice presentations, regulatory and accreditation preparation, preparation of tracking reports, as well as the development of both patient-level and HCPlevel tools, resources, and education materials. This forum facilitates collaborative learning: members process and synthesize information, share and reframe ideas, and listen to other viewpoints to gain a complete understanding as a group.⁵ For example, ASPWG members have leaned on each other to prepare for Joint Commission accreditation surveys and strengthen the VISN 8 COVID-19 program through the rollout of vaccines and treatments. Other collaborative projects completed over the past few years included a penicillin allergy testing initiative and anti-methicillin-resistant Staphylococcus aureus (MRSA) and pseudomonal medication use evaluations. This team-centric problem-solving approach is highly effective while also fostering professional and social relationships. However, collaboratives could be perceived to have drawbacks. There may be opportunity costs if ASP time is allocated for issues that have already been addressed locally or concerns that standardization might hinder rapid adoption of practices at individual sites. Therefore, participation in each distinct group initiative is optional. This allows sites to choose projects related to their high priority areas and maintain bandwidth to implement practices not yet adopted by the larger group.

The ASPWG tracks metrics related to antimicrobial use with quarterly data presented by the VISN pharmacist lead. Both inpatient and outpatient metrics are evaluated, such as days of therapy per 1000 days and outpatient antibiotic prescriptions per 1000 unique patients. Facilities are benchmarked against their own historical data and other VISN sites, as well as other VISNs across the country. When outliers are identified, facilities are encouraged to conduct local projects to identify reasons for different antimicrobial use patterns and subsequent initiatives to optimize antimicrobial use. Benchmarking against VISN facilities can be useful since VISN facilities may be more similar than facilities in different geographic regions. Each year, the ASPWG reviews the current metrics, makes adjustments to address VISN priorities, and votes for approval of the metrics that will be tracked in the coming year.

Participation in an ASP collaborative streamlines the rollout of ASP and quality improvement initiatives across multiple sites, allowing ASPs to impact a greater number of veterans and evaluate initiatives on a larger scale. In 2019, with the anticipation of revised vancomycin dosing and monitoring guidelines, our ASPWG began to strategize the transition to AUC-based vancomycin monitoring.⁶ This multisite initiative showcases the strengths of implementing and evaluating practice changes as part of an ASP collaborative.

Vancomycin Dosing

The antibiotic vancomycin is used primarily for the treatment of MRSA infections.⁶ The 2020 consensus guidelines for vancomycin therapeutic monitoring recommend using the AUC to minimum inhibitory concentration (MIC) ratio as the pharmacodynamic target for serious MRSA infections, with an AUC/MIC goal of 400 to 600 mcg*h/mL.⁶ Prior guidelines recommended using vancomycin trough concentrations of 15 to 20 mcg/mL as a surrogate for this AUC target. However, subsequent studies have shown that trough-based dosing is associated with higher vancomycin exposures, supratherapeutic AUCs, and increased risk of vancomycin-associated acute kidney injury (AKI).^7,8 Therefore, more direct AUC estimation is now recommended.⁶ The preferred approach for AUC calculations is through Bayesian modeling. Due to limited resources and software availability, many facilities use an alternative method involving 2 postdistributive serum vancomycin concentrations and first-order pharmacokinetic equations. This approach can optimize vancomycin dosing but is more mathematically and logistically challenging. Transitioning from troughto AUC-based vancomycin monitoring requires careful planning and comprehensive staff education.

In 2019, the VISN 8 ASPWG created a comprehensive vancomycin AUC toolkit to facilitate implementation. Components included a pharmacokinetic management policy and procedure, a vancomycin dosing guide, a progress note template, educational materials specific to pharmacy, nursing, laboratory, and medical services, a pharmacist competency examination, and a vancomycin AUC calculator (eAppendix). Each component was developed by a subgroup with the understanding that sites could incorporate variations based on local practices and needs.

The vancomycin AUC calculator was developed to be user-friendly and included safety validation protocols to prevent the entry of erroneous data (eg, unrealistic patient weight or laboratory values). The calculator allowed users to copy data into the electronic health record to avoid manual transcription errors and improve operational efficiency. It offered suggested volume of distribution estimates and 2 methods to estimate elimination constant (Ke ) depending on the patient’s weight.^9,10 Creatinine clearance could be estimated using serum creatinine or cystatin C and considered amputation history. The default AUC goal in the calculator was 400 to 550 mcg*h/mL. This range was chosen based on consensus guidelines, data suggesting increased risk of AKI with AUCs > 515 mcg*h/mL, and the preference for conservative empiric dosing in the generally older VA population.¹¹ The calculator suggested loading doses of about 25 mg/kg with a 2500 mg limit. VHA facilities could make limited modifications to the calculator based on local policies and procedures (eg, adjusting default infusion times or a dosing intervals).

The VISN 8 Pharmacy Pharmacokinetic Dosing Manual was developed as a comprehensive document to guide pharmacy staff with dosing vancomycin across diverse patient populations. This document included recommendations for renal function assessment, patient-specific considerations when choosing an empiric vancomycin dose, methods of ordering vancomycin peak, trough, and surveillance levels, dose determination based on 2 levels, and other clinical insights or frequently asked questions.

ASPWG members presented an accredited continuing education webinar for pharmacists, which reviewed the rationale for AUC-targeted dosing, changes to the current pharmacokinetic dosing program, case-based scenarios across various patient populations, and potential challenges associated with vancomycin AUC-based dosing. A recording of the live training was also made available. A vancomycin AUC dosing competency test was developed with 11 basic pharmacokinetic and case-based questions and comprehensive explanations provided for each answer.

VHA facilities implemented AUC dosing in a staggered manner, allowing for lessons learned at earlier adopters to be addressed proactively at later sites. The dosing calculator and education documents were updated iteratively as opportunities for improvement were discovered. ASPWG members held local office hours to address questions or concerns from staff at their facilities. Sharing standardized materials across the VISN reduced individual site workload and complications in rolling out this complex new process.

VISN-WIDE QUALITY ASSURANCE

At the time of project conception, 4 of 7 VISN 8 health systems had transitioned to AUC-based dosing. A quality assurance protocol to compare patient outcomes before and after changing to AUC dosing was developed. Each site followed local protocols for project approval and data were deidentified, collected, and aggregated for analysis.

The primary objectives were to compare the incidence of AKI and persistent bacteremia and assess rates of AUC target attainment (400-600 mcg*h/mL) in the AUC-based and trough-based dosing groups.⁶ Data for both groups included anthropomorphic measurements, serum creatinine, amputation status, vancomycin dosing, and infection characteristics. The X² test was used for categorical data and the t test was used for continuous data. A 2-tailed α of 0.05 was used to determine significance. Each site sequentially reviewed all patients receiving ≥ 48 hours of intravenous vancomycin over a 3-month period and contributed up to 50 patients for each group. Due to staggered implementation, the study periods for sites spanned 2018 to 2023. A minimum 6-month washout period was observed between the trough and AUC groups at each site. Patients were excluded if pregnant, receiving renal replacement therapy, or presenting with AKI at the time of vancomycin initiation.

There were 168 patients in the AUC group and 172 patients in the trough group (Table 1). The rate of AUC target attainment with the initial dosing regimen varied across sites from 18% to 69% (mean, 48%). Total daily vancomycin exposure was lower in the AUC group compared with the trough group (2402 mg vs 2605 mg, respectively), with AUC-dosed patients being less likely to experience troughs level ≥ 15 or 20 mcg/mL (Table 2). There was a statistically significant lower rate of AKI in the AUC group: 2.4% in the AUC group (range, 2%-3%) vs 10.4% (range 7%-12%) in the trough group (P = .002). Rates of AKI were comparable to those observed in previous interventions.⁶ There was no statistical difference in length of stay, time to blood culture clearance, or rate of persistent bacteremia in the 2 groups, but these assessments were limited by sample size.

We did not anticipate such variability in initial target attainment across sites. The multisite quality assurance design allowed for qualitative evaluation of variability in dosing practices, which likely arose from sites and individual pharmacists having some flexibility in adjusting dosing tool parameters. Further analysis revealed that the facility with low initial target attainment was not routinely utilizing vancomycin loading doses. Sites routinely use robust loading doses achieved earlier and more consistent target attainment. Some sites used a narrower AUC target range in certain clinical scenarios (eg, > 500 mcg*h/mL for septic patients and < 500 mcg*h/mL for patients with less severe infections) rather than the 400 to 550 mcg*h/mL range for all patients. Sites targeting broader AUC ranges for all patients had higher rates of target attainment. Reviewing differences among sites allowed the ASPWG to identify best practices to optimize future care.

CONCLUSIONS

VHA ASPs must meet the standards outlined in VHA Directive 1031, including the new requirement for each VISN to develop an ASP collaborative. The VISN 8 ASPWG demonstrates how ASP champions can collaborate to solve common issues, complete tasks, explore new infectious diseases concepts, and impact large veteran populations. Furthermore, ASP collaboratives can harness their collective size to complete robust quality assurance evaluations that might otherwise be underpowered if completed at a single center. A limitation of the collaborative model is that a site with a robust ASP may already have specific practices in place. Expanding the ASP collaborative model further highlights the VHA role as a nationwide leader in ASP best practices.

Case Presentation: A 65-year-old male veteran presented to the Veterans Affairs Boston Healthcare System (VABHS) emergency department with progressive fatigue, dyspnea on exertion, lightheadedness, and falls over the last month. New bilateral lower extremity numbness up to his knees developed in the week prior to admission and prompted him to seek care. Additional history included 2 episodes of transient loss of consciousness resulting in falls and a week of diarrhea, which had resolved. His medical history was notable for hypothyroidism secondary to Hashimoto thyroiditis, seizure disorder, vitiligo, treated hepatitis C virus (HCV) infection, alcohol use disorder in remission, diabetes mellitus, posttraumatic stress disorder, and traumatic brain injury. His medications included levothyroxine and carbamazepine. He previously worked as a barber but recently had stopped due to cognitive impairment. On initial evaluation, the patient's vital signs included a temperature of 36.3 °C, heart rate of 77 beats per minute, blood pressure of 139/83 mm Hg, respiratory rate of 18 breaths per minute, and 99% oxygen saturation while breathing ambient air. Physical examination was notable for a frail-appearing man in no acute distress. His conjunctivae were pale, and cardiac auscultation revealed a normal heart rate and irregularly irregular heart rhythm. A neurologic examination revealed decreased vibratory sensation in both feet, delayed and minimal speech, and a blunted affect. His skin was warm and dry with patchy hypopigmentation across the face and forehead. Laboratory results are shown in the Table. Testing 2 years previously found the patient's hemoglobin to be 11.4 g/dL and serum creatinine to be 1.7 mg/dL. A peripheral blood smear showed anisocytosis, hypochromia, decreased platelets, ovalocytes, elliptocytes, and rare teardrop cells, with no schistocytes present. Chest radiography and computed tomography of the head were unremarkable. An abdominal ultrasound revealed a complex hypoechoic mass with peripheral rim vascularity in the right hepatic lobe measuring 3.9 cm × 3.6 cm × 3.9 cm.

Lindsey Ulin, MD, Chief Medical Resident, VABHS and Brigham and Women’s Hospital (BWH):

To build the initial differential diagnosis, we are joined today by 3 internal medicine residents who were not involved in the care of this patient. Dr. Hickey, Dr. Ross and Dr. Manivannan, how did you approach this case?

Meghan Hickey, MD, Senior Internal Medicine Resident, VABHS and Boston Medical Center (BMC):

The constellation of fatigue, weakness, blunted affect, and delayed, minimal speech suggested central nervous system involvement, which I sought to unify with hemolytic anemia and his liver mass. The first diagnosis I considered was Wilson disease; however, this genetic disorder of copper metabolism often presents with liver failure or cirrhosis in young or middle-aged women, so this presentation would be atypical. Next, given the hypopigmentation was reported only on sun-exposed areas of the patient’s face, I considered possibilities other than vitiligo to avoid diagnostic anchoring. One such alternate diagnosis is porphyria cutanea tarda (PCT), which presents in middle-aged and older adults with a photosensitive dermatitis that can include acute sensory deficits. Manifestations of PCT can be triggered by alcohol consumption, though his alcohol use disorder was thought to be in remission, as well as HCV, for which he previously received treatment. However, anemia is uncommon in PCT, so the patient’s low hemoglobin would not be explained by this diagnosis. Lastly, I considered thrombotic thrombocytopenic purpura (TTP) given his anemia, thrombocytopenia, and neurologic symptoms; however, the patient did not have fever or a clear inciting cause, his renal dysfunction was relatively mild, and the peripheral blood smear revealed no schistocytes, which should be present in TTP.

Caroline Ross, MD, and Alan Manivannan, MD; Senior Internal Medicine Residents, VABHS and BMC:

We noted several salient features in the history and physical examination. First, we sought to explain the bilateral lower extremity numbness and decreased vibratory sensation in the feet leading to falls. We also considered his anemia and thrombocytopenia with signs of hemolysis including elevated lactate dehydrogenase (LDH), low haptoglobin, and elevated total bilirubin; however, with normal coagulation parameters. These results initially raised our concern for a thrombotic microangiopathy (TMA) such as TTP. However, the peripheral smear lacked schistocytes, making this less likely. The combination of his neurologic symptoms and TMA-like laboratory findings but without schistocytes raised our concern for vitamin B12 deficiency. Vitamin B12 deficiency can cause a pseudo-TMA picture with laboratory finding similar to TTP; however, schistocytes are typically absent. We also considered the possibility of hepatocellular carcinoma (HCC) with bone marrow infiltration leading to anemia given the finding of a liver mass on his abdominal ultrasound and low reticulocyte index. However, this would not explain his hemolysis. We also considered chronic disseminated intravascular coagulation in the setting of a malignancy as a contributor, but again, the smear lacked schistocytes and his coagulation parameters were normal. Finally, we considered a primary bone marrow process such as myelodysplastic syndrome due to the bicytopenia with poor bone marrow response and smear with tear drop cells and elliptocytes. However, we felt this was less likely as this would not explain his hemolytic anemia.

Dr. Ulin:

To refine the differential diagnosis, we are joined by an expert clinician who was also not involved in the care of this patient to describe his approach to this case. Dr. Orlander, can you walk us through your clinical reasoning?

Jay Orlander, MD, MPH: Professor of Medicine, Section of General Internal Medicine, Boston University Chobanian & Avedisian School of Medicine, Associate Chief, Medical Service, VABHS:

I will first comment on the hepatic mass. The hypoechoic liver mass with peripheral vascularity suggests a growing tumor. The patient has a history of substance use disorder with alcohol and treated HCV. He remains at increased risk for HCC even after prior successful HCV treatment and has 2 of 4 known risk factors for developing HCC— diabetes mellitus and alcohol use—the other 2 being underlying metabolic dysfunctionassociated steatotic liver disease (MASLD) and the presence of hepatic fibrosis, which we have not yet assessed. Worsening liver function can lead to cognitive issues and alcohol to peripheral neuropathy, but his story is not consistent with this. For his liver mass, I recommend a nonurgent magnetic resonance image for further evaluation.

Next, let’s consider his markedly elevated thyrotropin (TSH). Cognitive impairment along with lethargy, fatigue, and decreased exercise tolerance can be prominent features in severe hypothyroidism, but this diagnosis would not explain his hematologic findings.¹

I view the principal finding of his laboratory testing as being that his bone marrow is failing to maintain adequate blood elements. He has a markedly low hematocrit along with low platelets and low-normal white blood cell counts. There is an absence of schistocytes on the blood smear, and after correcting his reticulocyte count for his degree of anemia (observed reticulocyte percentage [0.8%] x observed hematocrit [15.3%] / expected hematocrit [40%]), results in a reticulocyte index of 0.12, which is low. This suggests his bone marrow is failing to manufacture red blood cells at an appropriate rate. His haptoglobin is unmeasurable, so there is some free heme circulating. Hence, I infer that hemolysis and ineffective erythropoiesis are both occurring within the bone marrow, which also explains the slight elevation in bilirubin.

Intramedullary hemolysis with a markedly elevated LDH can be seen in severe vitamin B₁₂ deficiency, which has many causes, but one cause in particular warrants consideration in this case: pernicious anemia. Pernicious anemia has an overall prevalence of about 0.1%, but is more common in older adults, and is estimated to be present in 2% to 3% of adults aged > 65 years.² Prevalence is also increased in patients with other autoimmune diseases such as vitiligo and hypothyroidism, which our patient has.³ The pathophysiology of pernicious anemia relates to either autoimmune gastric parietal cell destruction and/or the development of antibodies against intrinsic factor, which is required for absorption of vitamin B₁₂. Early disease may present with macrocytosis and a normal hemoglobin initially, but anemia develops over time if left untreated. When the primary cause of pernicious anemia is gastric parietal cell destruction, there is also an associated lack of stomach acid production (achlorhydria) with resulting poor micronutrient absorption; specifically, vitamin D, vitamin C, and iron. Hence, 30% of patients diagnosed with pernicious anemia have concurrent iron deficiency, which may counteract macrocytosis and result in a normal mean corpuscular volume. 4 Some medications are also poorly absorbed in achlorhydric states, such as levothyroxine, and treatment doses need to be increased, which could explain his markedly elevated TSH despite presumed medication adherence.

Vitamin B₁₂ is essential for both the peripheral and central nervous systems. Longstanding severe B₁₂ deficiency can explain all of his neurological and neurocognitive changes. The most common neurologic findings in B₁₂ deficiency are symmetric paresthesias or numbness and gait problems. The sensory neuropathy affects the lower extremities more commonly than the upper. Untreated, patients can develop progressive weakness, ataxia, and orthostatic hypotension with syncope, as well as neuropsychiatric changes including depression or mood impairment, cognitive slowing, forgetfulness, and dementia.

Dr. Ulin:

Dr. Orlander, which pieces of objective data are most important in forming your differential diagnosis, and what tests would you obtain next?

Dr. Orlander:

The 3 most salient laboratory tests to me are a complete blood count, with all cell lines impacted but the hemoglobin and hematocrit most dramatically impacted, reticulocyte count of 0.8%, which is inappropriately low and hence suggests a hypoproliferative anemia, and the elevated LDH > 5000 IU/L.

Since my suspected diagnosis is pernicious anemia, I would obtain a blood smear looking for hypersegmented neutrophils, > 1 white blood cells with 5 lobes, or 1 with 6 lobes, which should clinch the diagnosis. Methylmalonic acid (MMA) levels are the most sensitive test for B₁₂ deficiency, so I would also obtain that. Finally, I would check a B₁₂ level, since in a patient with pernicious anemia, I would expect the level to be < 200 pg/mL.

Dr. Ulin:

Before we reveal the results of the patient’s additional workup, how do you approach interpreting B₁₂ levels?

Dr. Orlander:

Measuring B12 can sometimes be problematic: the normal range is considered 200 to 900 pg/mL, but patients with measured low-normal levels in the range of 200 to 400 pg/mL can actually be physiologically deficient. There are also several common causes of falsely low and falsely high B₁₂ levels in the absence of B₁₂ deficiency. Hence, for patients with mild symptoms that could be due to B₁₂ deficiency, many clinicians choose to just treat with B₁₂ supplementation, deeming it safer to treat than miss an early diagnosis. B₁₂ is involved in hydrogen transfer to convert MMA into succinyl-CoA and hence true vitamin B₁₂ deficiency causes an increase in MMA.

Decreased production of vitamin B12 binding proteins, like haptocorrin, has been proposed as the mechanism for spurious low values.⁵ Certain conditions or medications can also cause spurious low serum vitamin B₁₂ levels and thus might cause the appearance of vitamin B₁₂ deficiency when the patient is not deficient. Examples include multiple myeloma, HIV infection, pregnancy, oral contraceptives, and phenytoin use. An example of spuriously low vitamin B₁₂ level in pregnancy was demonstrated in a series of 50 pregnant individuals with low vitamin B₁₂ levels (45-199 pg/mL), in whom metabolite testing for MMA and homocysteine showed no correlation with vitamin B₁₂ level.⁶

Further complicating things, some conditions can cause spuriously increased vitamin B₁₂ levels and thus might cause the appearance of normal vitamin B₁₂ levels when the patient is actually deficient.⁷ Examples include occult malignancy, myeloproliferative neoplasms, alcoholic liver disease, kidney disease, and nitrous oxide exposure (the latter of which is unique in that it can also cause true vitamin B₁₂ deficiency, as evidenced by clinical symptoms and high MMA levels).^8,9

Lastly, autoantibodies to intrinsic factor in individuals with pernicious anemia may compete with intrinsic factor in the chemiluminescence assay and result in spuriously normal vitamin B₁₂ levels in the presence of true deficiency.^10-12 If the vitamin B₁₂ level is very high (eg, 800 pg/mL), we do not worry about this effect in the absence of clinical features suggesting vitamin B₁₂ deficiency; however, if the vitamin B₁₂ level is borderline or low-normal and/or other clinical features suggest vitamin B₁₂ deficiency, it is prudent to obtain other testing such as an MMA level.

Dr. Ulin:

We are also joined by Dr. Rahul Ganatra, who cared for the patient at the time the diagnosis was made. Dr. Ganatra, can you share the final diagnosis and provide an update on the patient?

Rahul Ganatra, MD, MPH, Director of Continuing Medical Education, VABHS:

The patient’s hemoglobin rose to 6.9 g/dL after transfusion of 2 units of packed red blood cells, and his dyspnea on exertion and fatigue improved. Iron studies, serum thiamine, serum folate, ADAMTS13 activity levels, and AM cortisol level were normal. Upon closer examination of the peripheral blood smear, rare hypersegmented neutrophils were noted. Serum B₁₂ level returned below assay (< 146 pg/mL), and serum MMA was 50,800 nmol/L, confirming the diagnosis of severe vitamin B₁₂ deficiency. Antibodies against intrinsic factor were detected, confirming the diagnosis of pernicious anemia. Treatment was initiated with intramuscular cyanocobalamin every other day and was transitioned to weekly dosing at the time of hospital discharge. After excluding adrenal insufficiency, his levothyroxine dose was increased. Finally, a liver mass biopsy confirmed a concomitant diagnosis of HCC. The patient was discharged home. Five weeks after discharge, his serum B₁₂ level rose to > 1000 pg/mL, and 10 months after discharge, his TSH fell to 0.97 uIU/mL. Several months later, he underwent stereotactic body radiotherapy for the HCC. One year after his initial presentation, he has not resumed work as a barber.

Case Presentation: A 65-year-old male veteran presented to the Veterans Affairs Boston Healthcare System (VABHS) emergency department with progressive fatigue, dyspnea on exertion, lightheadedness, and falls over the last month. New bilateral lower extremity numbness up to his knees developed in the week prior to admission and prompted him to seek care. Additional history included 2 episodes of transient loss of consciousness resulting in falls and a week of diarrhea, which had resolved. His medical history was notable for hypothyroidism secondary to Hashimoto thyroiditis, seizure disorder, vitiligo, treated hepatitis C virus (HCV) infection, alcohol use disorder in remission, diabetes mellitus, posttraumatic stress disorder, and traumatic brain injury. His medications included levothyroxine and carbamazepine. He previously worked as a barber but recently had stopped due to cognitive impairment. On initial evaluation, the patient's vital signs included a temperature of 36.3 °C, heart rate of 77 beats per minute, blood pressure of 139/83 mm Hg, respiratory rate of 18 breaths per minute, and 99% oxygen saturation while breathing ambient air. Physical examination was notable for a frail-appearing man in no acute distress. His conjunctivae were pale, and cardiac auscultation revealed a normal heart rate and irregularly irregular heart rhythm. A neurologic examination revealed decreased vibratory sensation in both feet, delayed and minimal speech, and a blunted affect. His skin was warm and dry with patchy hypopigmentation across the face and forehead. Laboratory results are shown in the Table. Testing 2 years previously found the patient's hemoglobin to be 11.4 g/dL and serum creatinine to be 1.7 mg/dL. A peripheral blood smear showed anisocytosis, hypochromia, decreased platelets, ovalocytes, elliptocytes, and rare teardrop cells, with no schistocytes present. Chest radiography and computed tomography of the head were unremarkable. An abdominal ultrasound revealed a complex hypoechoic mass with peripheral rim vascularity in the right hepatic lobe measuring 3.9 cm × 3.6 cm × 3.9 cm.

Lindsey Ulin, MD, Chief Medical Resident, VABHS and Brigham and Women’s Hospital (BWH):

To build the initial differential diagnosis, we are joined today by 3 internal medicine residents who were not involved in the care of this patient. Dr. Hickey, Dr. Ross and Dr. Manivannan, how did you approach this case?

Meghan Hickey, MD, Senior Internal Medicine Resident, VABHS and Boston Medical Center (BMC):

The constellation of fatigue, weakness, blunted affect, and delayed, minimal speech suggested central nervous system involvement, which I sought to unify with hemolytic anemia and his liver mass. The first diagnosis I considered was Wilson disease; however, this genetic disorder of copper metabolism often presents with liver failure or cirrhosis in young or middle-aged women, so this presentation would be atypical. Next, given the hypopigmentation was reported only on sun-exposed areas of the patient’s face, I considered possibilities other than vitiligo to avoid diagnostic anchoring. One such alternate diagnosis is porphyria cutanea tarda (PCT), which presents in middle-aged and older adults with a photosensitive dermatitis that can include acute sensory deficits. Manifestations of PCT can be triggered by alcohol consumption, though his alcohol use disorder was thought to be in remission, as well as HCV, for which he previously received treatment. However, anemia is uncommon in PCT, so the patient’s low hemoglobin would not be explained by this diagnosis. Lastly, I considered thrombotic thrombocytopenic purpura (TTP) given his anemia, thrombocytopenia, and neurologic symptoms; however, the patient did not have fever or a clear inciting cause, his renal dysfunction was relatively mild, and the peripheral blood smear revealed no schistocytes, which should be present in TTP.

Caroline Ross, MD, and Alan Manivannan, MD; Senior Internal Medicine Residents, VABHS and BMC:

We noted several salient features in the history and physical examination. First, we sought to explain the bilateral lower extremity numbness and decreased vibratory sensation in the feet leading to falls. We also considered his anemia and thrombocytopenia with signs of hemolysis including elevated lactate dehydrogenase (LDH), low haptoglobin, and elevated total bilirubin; however, with normal coagulation parameters. These results initially raised our concern for a thrombotic microangiopathy (TMA) such as TTP. However, the peripheral smear lacked schistocytes, making this less likely. The combination of his neurologic symptoms and TMA-like laboratory findings but without schistocytes raised our concern for vitamin B12 deficiency. Vitamin B12 deficiency can cause a pseudo-TMA picture with laboratory finding similar to TTP; however, schistocytes are typically absent. We also considered the possibility of hepatocellular carcinoma (HCC) with bone marrow infiltration leading to anemia given the finding of a liver mass on his abdominal ultrasound and low reticulocyte index. However, this would not explain his hemolysis. We also considered chronic disseminated intravascular coagulation in the setting of a malignancy as a contributor, but again, the smear lacked schistocytes and his coagulation parameters were normal. Finally, we considered a primary bone marrow process such as myelodysplastic syndrome due to the bicytopenia with poor bone marrow response and smear with tear drop cells and elliptocytes. However, we felt this was less likely as this would not explain his hemolytic anemia.

Dr. Ulin:

To refine the differential diagnosis, we are joined by an expert clinician who was also not involved in the care of this patient to describe his approach to this case. Dr. Orlander, can you walk us through your clinical reasoning?

Jay Orlander, MD, MPH: Professor of Medicine, Section of General Internal Medicine, Boston University Chobanian & Avedisian School of Medicine, Associate Chief, Medical Service, VABHS:

I will first comment on the hepatic mass. The hypoechoic liver mass with peripheral vascularity suggests a growing tumor. The patient has a history of substance use disorder with alcohol and treated HCV. He remains at increased risk for HCC even after prior successful HCV treatment and has 2 of 4 known risk factors for developing HCC— diabetes mellitus and alcohol use—the other 2 being underlying metabolic dysfunctionassociated steatotic liver disease (MASLD) and the presence of hepatic fibrosis, which we have not yet assessed. Worsening liver function can lead to cognitive issues and alcohol to peripheral neuropathy, but his story is not consistent with this. For his liver mass, I recommend a nonurgent magnetic resonance image for further evaluation.

Next, let’s consider his markedly elevated thyrotropin (TSH). Cognitive impairment along with lethargy, fatigue, and decreased exercise tolerance can be prominent features in severe hypothyroidism, but this diagnosis would not explain his hematologic findings.¹

I view the principal finding of his laboratory testing as being that his bone marrow is failing to maintain adequate blood elements. He has a markedly low hematocrit along with low platelets and low-normal white blood cell counts. There is an absence of schistocytes on the blood smear, and after correcting his reticulocyte count for his degree of anemia (observed reticulocyte percentage [0.8%] x observed hematocrit [15.3%] / expected hematocrit [40%]), results in a reticulocyte index of 0.12, which is low. This suggests his bone marrow is failing to manufacture red blood cells at an appropriate rate. His haptoglobin is unmeasurable, so there is some free heme circulating. Hence, I infer that hemolysis and ineffective erythropoiesis are both occurring within the bone marrow, which also explains the slight elevation in bilirubin.

Intramedullary hemolysis with a markedly elevated LDH can be seen in severe vitamin B₁₂ deficiency, which has many causes, but one cause in particular warrants consideration in this case: pernicious anemia.

Several months later, he underwent stereotactic body radiotherapy for the HCC. One year after his initial presentation, he has not resumed work as a barber.

The COVID-19 pandemic established a new normal for health care delivery, with leaders rethinking core practices to survive and thrive in a changing environment and improve the health and well-being of patients. The Veterans Health Administration (VHA) is embracing a shift in focus from “what is the matter” to “what really matters” to address pre- and postpandemic challenges through a whole health approach.¹ Initially conceptualized by the VHA in 2011, whole health “is an approach to health care that empowers and equips people to take charge of their health and well-being so that they can live their life to the fullest.”¹ Whole health integrates evidence-based complementary and integrative health (CIH) therapies to manage pain; this includes acupuncture, meditation, tai chi, yoga, massage therapy, guided imagery, biofeedback, and clinical hypnosis.¹ The VHA now recognizes well-being as a core value, helping clinicians respond to emerging challenges related to the social determinants of health (eg, access to health care, physical activity, and healthy foods) and guiding health care decision making.^1,2

Well-being through empowerment—elements of whole health and Age-Friendly Health Systems (AFHS)—encourages health care institutions to work with employees, patients, and other stakeholders to address global challenges, clinician burnout, and social issues faced by their communities. This approach focuses on life’s purpose and meaning for individuals and inspires leaders to engage with patients, staff, and communities in new, impactful ways by focusing on wellbeing and wholeness rather than illness and disease. Having a higher sense of purpose is associated with lower all-cause mortality, reduced risk of specific diseases, better health behaviors, greater use of preventive services, and fewer hospital days of care.³

This article describes how AFHS supports the well-being of older adults and aligns with the whole health model of care. It also outlines the VHA investment to transform health care to be more person-centered by documenting what matters in the electronic health record (EHR).

AGE-FRIENDLY CARE

Given that nearly half of veterans enrolled in the VHA are aged ≥ 65 years, there is an increased need to identify models of care to support this aging population.⁴ This is especially critical because older veterans often have multiple chronic conditions and complex care needs that benefit from a whole person approach. The AFHS movement aims to provide evidence-based care aligned with what matters to older adults and provides a mechanism for transforming care to meet the needs of older veterans. This includes addressing age-related health concerns while promoting optimal health outcomes and quality of life. AFHS follows the 4Ms framework: what matters, medication, mentation, and mobility.⁵ The 4Ms serve as a guide for the health care of older adults in any setting, where each “M” is assessed and acted on to support what matters.⁵ Since 2020, > 390 teams have developed a plan to implement the 4Ms at 156 VHA facilities, demonstrating the VHA commitment to transforming health care for veterans.⁶

When VHA teams join the AFHS movement, they may also engage older veterans in a whole health system (WHS) (Figure). While AFHS is designed to improve care for patients aged ≥ 65 years, it also complements whole health, a person-centered approach available to all veterans enrolled in the VHA. Through the WHS and AFHS, veterans are empowered and equipped to take charge of their health and well-being through conversations about their unique goals, preferences, and health priorities.⁴ Clinicians are challenged to assess what matters by asking questions like, “What brings you joy?” and, “How can we help you meet your health goals?”^1,5 These questions shift the conversation from disease-based treatment and enable clinicians to better understand the veteran as a person.^1,5

For whole health and AFHS, conversations about what matters are anchored in the veteran’s goals and preferences, especially those facing a significant health change (ie, a new diagnosis or treatment decision).^5,7 Together, the veteran’s goals and priorities serve as the foundation for developing person-centered care plans that often go beyond conventional medical treatments to address the physical, mental, emotional, and social aspects of health.

SYSTEM-WIDE DIRECTIVE

The WHS enhances AFHS discussions about what matters to veterans by adding a system-level lens for conceptualizing health care delivery by leveraging the 3 components of WHS: the “pathway,” well-being programs, and whole health clinical care.

The Pathway

Discovering what matters, or the veteran’s “mission, aspiration, and purpose,” begins with the WHS pathway. When stepping into the pathway, veterans begin completing a personal health inventory, or “walking the circle of health,” which encourages self-reflection that focuses on components of their life that can influence health and well-being.^1,8 The circle of health offers a visual representation of the 4 most important aspects of health and well-being: First, “Me” at the center as an individual who is the expert on their life, values, goals, and priorities. Only the individual can know what really matters through mindful awareness and what works for their life. Second, self-care consists of 8 areas that impact health and wellbeing: working your body; surroundings; personal development; food and drink; recharge; family, friends, and coworkers; spirit and soul; and power of the mind. Third, professional care consists of prevention, conventional care, and complementary care. Finally, the community that supports the individual.

Well-Being Programs

VHA provides WHS programs that support veterans in building self-care skills and improving their quality of life, often through integrative care clinics that offer coaching and CIH therapies. For example, a veteran who prioritizes mobility when seeking care at an integrative care clinic will not only receive conventional medical treatment for their physical symptoms but may also be offered CIH therapies depending on their goals. The veteran may set a daily mobility goal with their care team that supports what matters, incorporating CIH approaches, such as yoga and tai chi into the care plan.⁵ These holistic approaches for moving the body can help alleviate physical symptoms, reduce stress, improve mindful awareness, and provide opportunities for self-discovery and growth, thus promote overall well-being

Whole Health Clinical Care

AFHS and the 4Ms embody the clinical care component of the WHS. Because what matters is the driver of the 4Ms, every action taken by the care team supports wellbeing and quality of life by promoting independence, connection, and support, and addressing external factors, such as social determinants of health. At a minimum, well-being includes “functioning well: the experience of positive emotions such as happiness and contentment as well as the development of one’s potential, having some control over one’s life, having a sense of purpose, and experiencing positive relationships.”⁹ From a system perspective, the VHA has begun to normalize focusing on what matters to veterans, using an interprofessional approach, one of the first steps to implementing AFHS.

As the programs expand, AFHS teams can learn from whole health well-being programs and increase the capacity for self-care in older veterans. Learning about the key elements included in the circle of health helps clinicians understand each veteran’s perceived strengths and weaknesses to support their self-care. From there, teams can act on the 4Ms and connect older veterans with the most appropriate programs and services at their facility, ensuring continuum of care.

DOCUMENTATION

The VHA leverages several tools and evidence-based practices to assess and act on what matters for veterans of all ages (Table).^5,10-16 The VHA EHR and associated dashboards contain a wealth of information about whole health and AFHS implementation, scale up, and spread. A national AFHS 4Ms note template contains standardized data elements called health factors, which provide a mechanism for monitoring 4Ms care via its related dashboard. This template was developed by an interprofessional workgroup of VHA staff and underwent a thorough human factors engineering review and testing process prior to its release. Although teams continue to personalize care based on what matters to the veteran, data from the standardized 4Ms note template and dashboard provide a way to establish consistent, equitable care across multiple care settings.¹⁷

Between January 2022 and December 2023, > 612,000 participants aged ≥ 65 years identified what matters to them through 1.35 million assessments. During that period, > 36,000 veterans aged ≥ 65 years participated in AFHS and had what matters conversations documented. A personalized health plan was completed by 585,270 veterans for a total of 1.1 million assessments.11 Whole health coaching has been documented for > 57,000 veterans with > 200,000 assessments completed.¹³ In fiscal year 2023, a total of 1,802,131 veterans participated in whole health.

When teams share information about what matters to the veteran in a clinicianfacing format in the EHR, this helps ensure that the VHA honors veteran preferences throughout transitions of care and across all phases of health care. Although the EHR captures data on what matters, measurement of the overall impact on veteran and health system outcomes is essential. Further evaluation and ongoing education are needed to ensure clinicians are accurately and efficiently capturing the care provided by completing the appropriate EHR. Additional challenges include identifying ways to balance the documentation burden, while ensuring notes include valuable patient-centered information to guide care. EHR tools and templates have helped to unlock important insights on health care delivery in the VHA; however, health systems must consider how these clinical practices support the overall well-being of patients. How leaders empower frontline clinicians in any care setting to use these data to drive meaningful change is also important.

TRANSFORMING VHA CARE DELIVERY

In Achieving Whole Health: A New Approach for Veterans and the Nation, the National Academy of Science proposes a framework for the transformation of health care institutions to provide better whole health to veterans.³ Transformation requires change in entire systems and leaders who mobilize people “for participation in the process of change, encouraging a sense of collective identity and collective efficacy, which in turn brings stronger feelings of self-worth and self-efficacy,” and an enhanced sense of meaningfulness in their work and lives.¹⁸

Shifting health care approaches to equipping and empowering veterans and employees with whole health and AFHS resources is transformational and requires radically different assumptions and approaches that cannot be realized through traditional approaches. This change requires robust and multifaceted cultural transformation spanning all levels of the organization. Whole health and AFHS are facilitating this transformation by supporting documentation and data needs, tracking outcomes across settings, and accelerating spread to new facilities and care settings nationwide to support older veterans in improving their health and well-being.

Whole health and AFHS are complementary approaches to care that can work to empower veterans (as well as caregivers and clinicians) to align services with what matters most to veterans. Lessons such as standardizing person-centered assessments of what matters, creating supportive structures to better align care with veterans’ priorities, and identifying meaningful veteran and system-level outcomes to help sustain transformational change can be applied from whole health to AFHS. Together these programs have the potential to enhance overall health outcomes and quality of life for veterans.

Gonococcal infections, which are caused by the sexually transmitted, gram-negative diplococcus Neisseria gonorrhoeae, are a current and increasing threat to public health. Between 2012 and 2021, the rate of gonococcal infection in the United States increased 137.8% in men and 64.9% in women,¹ with an estimated 1.5 million new gonococcal infections occurring each year in the United States as of 2021.²Neisseria gonorrhoeae is the second most common bacterial sexually transmitted infection (STI), and patients with gonococcal infection frequently are coinfected with Chlamydia trachomatis, which is the most common bacterial STI. Uncomplicated gonococcal infection (also known as gonorrhea) most commonly causes asymptomatic cervicovaginal infection in women and symptomatic urethral infection in men.² Other uncomplicated manifestations include rectal infection, which can be asymptomatic or manifest with anal pruritus, anal discharge, or tenesmus, and oropharyngeal infection, which can be asymptomatic or manifest with throat pain. If uncomplicated gonococcal infections are left untreated or are incompletely treated, serious complications including septic arthritis, myositis, osteomyelitis, myocarditis, endocarditis, and meningitis might occur.^2-5 Ascending, locally invasive infections can cause epididymitis or pelvic inflammatory disease, which is an important cause of infertility in women.^2,3 Gonococcal conjunctivitis also can occur, particularly when neonates are exposed to bacteria during vaginal delivery. Although rare, gonococcal bacteria can disseminate widely, with an estimated 0.5% to 3% of uncomplicated gonococcal infections progressing to disseminated gonococcal infection (DGI).^3-6 Because DGI can mimic other systemic conditions, including a variety of bacterial and viral infections as well as inflammatory conditions, it can be difficult to diagnose without a high index of clinical suspicion. We present a case of DGI diagnosed based on dermatologic expertise and pharyngeal molecular testing.

A 30-year-old man presented to the emergency department with a rash on the extremeities as well as emesis, fever, sore throat, and severe arthralgia in the wrists, hands, knees, and feet of 2 days’ duration. The patient also had experienced several months of dysuria. He reported daily use of the recreational drug ketamine, multiple new male sexual partners, and unprotected oral and receptive anal sex in recent months. He denied any history of STIs. Physical examination demonstrated tender edematous wrists and fingers, papulovesicles on erythematous bases on the palms, and purpuric macules scattered on the legs (Figure 1). The patient also had tonsillar edema with notable white tonsillar exudate.

Between 2012 and 2021, the rate of gonococcal infection in the United States increased 137.8% in men and 64.9% in women,¹ with an estimated 1.5 million new gonococcal infections occurring each year in the United States as of 2021.²Neisseria gonorrhoeae is the second most common bacterial sexually transmitted infection (STI), and patients with gonococcal infection frequently are coinfected with Chlamydia trachomatis, which is the most common bacterial STI. Uncomplicated gonococcal infection (also known as gonorrhea) most commonly causes asymptomatic cervicovaginal infection in women and symptomatic urethral infection in men.² Other uncomplicated manifestations include rectal infection, which can be asymptomatic or manifest with anal pruritus, anal discharge, or tenesmus, and oropharyngeal infection, which can be asymptomatic or manifest with throat pain. If uncomplicated gonococcal infections are left untreated or are incompletely treated, serious complications including septic arthritis, myositis, osteomyelitis, myocarditis, endocarditis, and meningitis might occur.^2-5 Ascending, locally invasive infections can cause epididymitis or pelvic inflammatory disease, which is an important cause of infertility in women.^2,3 Gonococcal conjunctivitis also can occur, particularly when neonates are exposed to bacteria during vaginal delivery. Although rare, gonococcal bacteria can disseminate widely, with an estimated 0.5% to 3% of uncomplicated gonococcal infections progressing to disseminated gonococcal infection (DGI).^3-6 Because DGI can mimic other systemic conditions, including a variety of bacterial and viral infections as well as inflammatory conditions, it can be difficult to diagnose without a high index of clinical suspicion. We present a case of DGI diagnosed based on dermatologic expertise and pharyngeal molecular testing.

A 30-year-old man presented to the emergency department with a rash on the extremeities as well as emesis, fever, sore throat, and severe arthralgia in the wrists, hands, knees, and feet of 2 days’ duration. The patient also had experienced several months of dysuria. He reported daily use of the recreational drug ketamine, multiple new male sexual partners, and unprotected oral and receptive anal sex in recent months. He denied any history of STIs. Physical examination demonstrated tender edematous wrists and fingers, papulovesicles on erythematous bases on the palms, and purpuric macules scattered on the legs (Figure 1). The patient also had tonsillar edema with notable white tonsillar exudate.

Biologics have revolutionized dermatologic treatment, offering substantial relief from chronic and ­debilitating skin conditions such as psoriasis, hidradenitis suppurativa, atopic dermatitis (AD), chronic urticaria, and immunobullous diseases (eg, pemphigus vulgaris, bullous pemphigoid). By drastically decreasing symptom burden, biologics have the potential to transform patients’ lives by improving their overall quality of life (QOL). However, the use of biologics during ­pregnancy raises critical considerations, especially ­regarding safety.

Biologics for Cutaneous Conditions

Biologics—tumor necrosis factor (TNF) α inhibitors; IL-17, IL-23, IL-12, and IL-36 inhibitors; and agents such as omalizumab and dupilumab—have shown remarkable efficacy in controlling severe or recalcitrant dermatologic conditions and typically are more effective than traditional systemic therapies.¹ For instance, randomized clinical trials (RCTs) and real-world data have shown that patients with psoriasis can achieve considerable skin clearance with biologics, greatly enhancing QOL.² Adalimumab and secukinumab, which have been approved for use in moderate to severe cases of hidradenitis suppurativa, reduce the frequency of painful nodules and abscesses, thereby decreasing pain and improving QOL. Dupilumab, an IL-4/13 receptor antagonist, has revolutionized the treatment of AD by drastically reducing itch and skin lesions and improving QOL.³ For chronic urticaria, the anti-IgE antibody omalizumab has effectively reduced the incidence of hives and itching, providing pronounced symptom relief when traditional antihistamines fail.⁴ Use of rituximab, an anti-CD20 monoclonal antibody, has led to remission in severe cases of pemphigus vulgaris and bullous pemphigoid.⁵

Impact of Untreated Cutaneous Conditions in Pregnancy

When treating patients who are pregnant, dermatologists must consider the health of both the expectant mother and the developing fetus. This dual focus complicates decision-making, particularly with the use of biologics. Untreated cutaneous conditions can profoundly impact a pregnant patient’s health and QOL as well as lead to pregnancy complications affecting the fetus, such as preterm birth or low birth weight. In some studies, moderate to severe psoriasis has been associated with increased risk for complications during pregnancy, including preeclampsia and intrauterine growth restriction.⁶ Although specific data on hidradenitis suppurativa are lacking, the highly inflammatory nature of the condition suggests similar adverse effects on pregnancy.⁷ Atopic dermatitis can be exacerbated during pregnancy due to a shift in the immune system to become more allergic dominant.⁸ Generalized pustular psoriasis manifests with widespread pustules, fever, and systemic inflammation, posing serious risks to both the mother and the fetus if left untreated⁹; in such a life-threatening scenario, the use of potent treatments such as spesolimab, an IL-36 receptor antagonist, may be warranted. Therefore, managing these conditions effectively is crucial not only for the mother’s health but also for fetal well-being.

Which Biologics Can Dermatologists Safely Prescribe?

Despite the benefits, many dermatologists are hesitant to prescribe biologics to pregnant patients due to the lack of understanding and definitive safety data.^10,11 Although there are no RCTs that involve pregnant patients, current evidence suggests that several biologics are not teratogenic and do not cause fetal malformations. Extensive postexposure data support the safety of TNF-α inhibitors during pregnancy.¹² Research has shown that children exposed to these agents in utero have normal development, infection rates, and vaccination outcomes comparable to nonexposed children. For example, a systematic review and meta-analysis found no significant increase in the risk for major congenital malformations, spontaneous abortions, or preterm births among patients exposed to anti–TNF-α agents during pregnancy.² The Organization of Teratology Information Specialists Autoimmune Diseases in Pregnancy Project has provided valuable real-world data indicating that the use of TNF-α inhibitors in pregnancy, particularly during the first trimester, does not substantially elevate the risk for adverse outcomes.¹³ These findings have been corroborated by several other registry studies and RCTs, providing a robust safety profile for these agents during pregnancy.¹⁴

Similarly, postexposure data on IL-17 and IL-12/23 inhibitors indicate a favorable safety profile, though the sample sizes are smaller than those for anti–TNF-α agents.^12,14 Studies of drugs such as secukinumab (IL-17 inhibitor), guselkumab (IL-23 inhibitor), or ustekinumab (IL-12/23 inhibitor) have shown no association with teratogenic effects or increased risk for miscarriage.¹⁴ However, agents such as spesolimab (IL-36 inhibitor) are relatively new, and ongoing studies are expected to provide more comprehensive safety data.¹⁵ Similarly, omalizumab and dupilumab have not been associated with increased risk for fetal malformations or adverse pregnancy outcomes. Omalizumab, indicated for chronic urticaria, has a good safety profile in pregnancy, with no significant increase in adverse outcomes reported in studies and registries.¹⁶ Dupilumab, used for AD, has demonstrated safety in pregnancy, with ongoing studies continuing to monitor outcomes.¹⁷

Conversely, rituximab (an anti-CD20 antibody for autoimmune bullous diseases) has shown evidence of adverse pregnancy outcomes, including fetal harm.¹⁸ Its use generally is discouraged unless deemed absolutely necessary, and no safer alternatives are available. Rituximab can cross the placenta, especially in the second and third trimesters, and has been associated with B-cell depletion in the fetus, leading to potential immunosuppression and increased risk for infections.⁵

Although the data on the safety of biologics in pregnancy are largely reassuring, it is essential to recognize that potential risks have not been ruled out entirely. There are extensive safety data for anti–TNF-α inhibitors, which provides a level of confidence; although newer agents such as IL-17 and IL-23 inhibitors have shown promising early results, further research is required to solidify their safety profiles during pregnancy.

Dermatologists must balance the risks and benefits of using biologics in pregnant patients. This decision-­making process involves careful consideration of the severity of the mother’s condition, the potential risks to the fetus, and the availability of alternative treatments. For many severe dermatologic conditions, the benefits of biologics in controlling disease activity and improving QOL may outweigh the potential risks, especially when other treatments have failed or are not suitable.

Final Thoughts

The increasing use of biologics in dermatology has undoubtedly improved the management of severe skin conditions, substantially enhancing patients’ QOL. As more data become available and clinical guidelines evolve, health care providers will be better equipped to make informed decisions about the use of biologics, particularly in pregnant patients. Collaborative efforts between dermatologists, obstetricians, and researchers will help refine treatment guidelines and ensure that pregnant patients with severe dermatologic conditions receive the best possible care.

For now, although the current evidence supports the safety of many biologics during pregnancy,^10,11 individualized care and informed decision-making remain paramount. Careful management and adherence to current guidelines make it possible to navigate the complexities of treating severe dermatologic conditions in pregnant patients, ensuring the best outcomes for both mother and child.
