Extracorporeal membrane oxygen support appears to be beneficial in patients with advanced interstitial lung disease (ILD), according to a new meta-analysis. Specifically, among patients undergoing ECMO as a bridge to transplant, mortality was lower with venoarterial (VA) ECMO than with venovenous (VV) ECMO, although the confidence in the finding was low.

ECMO has been used increasingly in ILD patients over the past 10-15 years for acute decompensation as well as a bridge to lung transplant, according to Prasanth Balasubramanian, MD, but clinical evidence for its use is limited to case series or short-term retrospective studies. “We don’t have robust evidence on whether it really helps with the outcome, and which mode is better, so that’s why we decided to do a study on this,” said Dr. Balasubramanian, who is a fellow in pulmonary critical care at Mayo Clinic (Jacksonville, Fla.). He presented the new research at the annual meeting of the American College of Chest Physicians (CHEST).

The results were encouraging, according to the study’s lead author Pramod Guru, MD. “I think what we take from this analysis is that ECMO should not be considered as a contraindication for people you are considering for lung transplant. If we have this population of people who are very sick, but we have the opportunity to solve them with VA ECMO and then give the transplantation possibly, that may be the way,” said Dr. Guru, who is a critical care specialist at Mayo Clinic, Jacksonville, Fla. He acknowledged that more work needs to be done to determine whether VA or VV is best in specific patient populations.

The meta-analysis included 18 studies with a total of 1,341 patients, who were a mean age of 55.89 years and 61.08% of whom were male. Most procedures (75.3%) were VV. The overall mortality was 52.6%, including 59.7% for VV ECMO and 34.2% for VA ECMO. The survival difference did not reach statistical significance (odds ratio, 0.48; P = .11). There was also no significant difference in survival between patients who underwent ECMO and those who did not undergo ECMO (OR, 0.48; P = .43).

The researchers also analyzed 13 studies with 1,002 patients that looked at ECMO as a bridge to transplant (mean age, 52.1; 52.2% male; 49.3% VV, 31.1% VA, 32.4% cardiopulmonary bypass). Mortality was lower in the VA group than in the VV group (odds ratio, 0.62; P = .04).

“VA ECMO is generally for sicker patients, so it’s odd that the patients who are on the more aggressive support had lower mortality. But it’s good, it says it works,” said Chris Carroll, MD, an intensivist at the University of Florida, Jacksonville, who was asked to comment on the study.

The finding may also be an artifact of bias in the retrospective data, according to Joshua Diamond, MD, who comoderated the session where the study was presented. He noted age, physical function, and illness severity, among other factors can play a role in decision-making. “I have a feeling that what you’re seeing is a very carefully selected patient population as opposed to a true mortality benefit with VA versus VV ECMO,” said Dr. Diamond, who is associate medical director of the Penn Lung Transplant Program in Philadelphia.

Another weakness of the study is that ECMO techniques and devices have changed over time, making some of the older data less relevant to current practice. Overall Dr. Diamond described the study as interesting, but “I’d like to see a bit more granularity of data to figure out who makes or doesn’t make a good candidate,” said Dr. Diamond.

Patients with ILD undergoing ECMO as a bridge to transplant had a higher 1-year posttransplant mortality than patients with other causes for transplant (OR, 1.78; P<.01). However, this finding relied on two retrospective studies using the UNOS database at different time points (2001-2012 and 2015-2020), leading to potential confounders and risk of bias.

Dr. Balasubramanian recognized the limitations of the analysis. “We do think that further prospective studies comparing various modalities would be essential, although it would be challenging,” he said.

Nevertheless, Dr. Guru said that his own center is changing its patient selection criteria for ECMO and will begin to collect prospective data: “I would say that in 12 months we’ll have our own data to support what we are doing.”

The study can also inform patients and family who are trying to make a potential end-of-life decision about pursuing aggressive ECMO therapy. “This study says that if you choose to pursue that more aggressive therapy, you may still have a good outcome. A patient might say, ‘Why am I going to go through all this? Is it just prolonging my death, or is there a chance of saving my life? I think what this study shows is that it does have potential of saving their life,” said Dr. Carroll.

Dr. Balasubramanian, Dr. Guru, and Dr. Carroll have no relevant financial disclosures.

To the Editor:

Plaquelike or plaque-type syringoma is a lesser-known variant of syringoma that can appear histologically indistinguishable from the superficial portion of microcystic adnexal carcinoma (MAC). The plaquelike variant of syringoma holds a benign clinical course, and no treatment is necessary. Microcystic adnexal carcinoma is distinguished from plaquelike syringoma by an aggressive growth pattern with a high risk for local invasion and recurrence if inadequately treated. Thus, treatment with Mohs micrographic surgery (MMS) has been recommended as the mainstay for MAC. If superficial biopsy specimens reveal suspicion for MAC and patients are referred for MMS, careful consideration should be made to differentiate MAC and plaquelike syringoma early to prevent unnecessary morbidity.

A 78-year-old woman was referred for MMS for a left forehead lesion that was diagnosed via shave biopsy as a desmoplastic and cystic adnexal neoplasm with suspicion for desmoplastic trichoepithelioma or MAC (Figure 1). Upon presentation for MMS, a well-healed, 1.0×0.9-cm scar at the biopsy site on the left forehead was observed (Figure 2A). One stage was obtained by standard MMS technique and sent for intraoperative processing (Figure 2B). Frozen section examination of the first stage demonstrated peripheral margin involvement with syringomatous change confined to the superficial and mid dermis (Figure 3). Before proceeding further, these findings were reviewed with an in-house dermatopathologist, and it was determined that no infiltrative tumor, perineural involvement, or other features to indicate malignancy were noted. A decision was made to refrain from obtaining any additional layers and to send excised Burow triangles for permanent section analysis. A primary linear closure was performed without complication, and the patient was discharged from the ambulatory surgery suite. Histopathologic examination of the Burow triangles later confirmed findings consistent with plaquelike syringoma with no evidence of malignancy (Figure 4).

Syringomas present as small flesh-colored papules in the periorbital areas. These benign neoplasms previously have been classified into 4 major clinical variants: localized, generalized, Down syndrome associated, and familial.¹ The lesser-known plaquelike variant of syringoma was first described by Kikuchi et al² in 1979. Aside from our report, a PubMed search of articles indexed for MEDLINE using the terms plaquelike or plaque-type syringoma yielded 16 cases in the literature.^2-14 Of these, 6 were referred to or encountered in the MMS setting.^8,9,11,12,14 Plaquelike syringoma can be solitary or multiple in presentation.⁶ It most commonly involves the head and neck but also can present on the trunk, arms, legs, and groin areas. The clinical size of plaquelike syringoma is variable, with the largest reported cases extending several centimeters in diameter.^2,6 Similar to reported associations with conventional syringoma, the plaquelike subtype of syringoma has been reported in association with Down syndrome.¹³

Histopathologically, plaquelike syringoma shares features with MAC as well as desmoplastic trichoepithelioma and desmoplastic basal cell carcinoma. Plaquelike syringoma demonstrates broad proliferations of small tubules morphologically reminiscent of tadpoles confined within the dermis. Ducts typically are lined with 2 or 3 layers of small cuboidal cells. Microcystic adnexal carcinoma typically features asymmetric ductal structures lined with single cells extending from the dermis into the subcutis and even underlying muscle, cartilage, or bone.⁸ There are no reliable immunohistochemical stains to differentiate between these 2 entities; thus, the primary distinction lies in the depth of involvement. Desmoplastic trichoepithelioma is composed of narrow cords and nests of basaloid cells of follicular origin commonly admixed with small cornifying cysts appearing in the dermis.⁸ Colonizing Merkel cells positive for cytokeratin 20 often are present in desmoplastic trichoepithelioma and not in syringoma or MAC.¹⁵ Desmoplastic basal cell carcinoma demonstrates narrow strands of basaloid cells of follicular origin appearing in the dermis. Desmoplastic trichoepithelioma and desmoplastic basal cell carcinoma are each fundamentally differentiated from plaquelike syringoma in that proliferations of cords and nests are not of eccrine or apocrine origin.

Several cases of plaquelike syringoma have been challenging to distinguish from MAC in performing MMS.^8,9,11 Underlying extension of this syringoma variant can be far-reaching, extending to several centimeters in size and involving multiple cosmetic subunits.^6,11,14 Inadvertent overtreatment with multiple MMS stages can be avoided with careful recognition of the differentiating histopathologic features. Syringomatous lesions commonly are encountered in MMS and may even be present at the edge of other tumor types. Plaquelike syringoma has been reported as a coexistent entity with nodular basal cell carcinoma.¹² Boos et al¹⁶ similarly reported the presence of deceptive ductal proliferations along the immediate peripheral margin of MAC, which prompted multiple re-excisions. Pursuit of permanent section analysis in these cases revealed the appearance of small syringomas, and a diagnosis of benign subclinical syringomatous proliferations was made, averting further intervention.¹⁶

Our case sheds light on the threat of commission bias in dermatologic surgery, which is the tendency for action rather than inaction.¹⁷ In this context, it is important to avoid the perspective that harm to the patient can only be prevented by active intervention. Cognitive bias has been increasingly recognized as a source of medical error, and methods to mitigate bias in medical practice have been well described.¹⁷ Microcystic adnexal carcinoma and plaquelike syringoma can be hard to differentiate especially initially, as demonstrated in our case, which particularly illustrates the importance of slowing down a surgical case at the appropriate time, considering and revisiting alternative diagnoses, implementing checklists, and seeking histopathologic collaboration with colleagues when necessary. Our attempted implementation of these principles, especially early collaboration with colleagues, led to intraoperative recognition of plaquelike syringoma within the first stage of MMS.

We seek to raise the index of suspicion for plaquelike syringoma among dermatologists and dermatologic surgeons, especially when syringomatous structures are limited to the superficial dermis. We encourage familiarity with the plaquelike syringoma entity as well as careful consideration of further investigation via scouting biopsies or permanent section analysis when other characteristic features of MAC are unclear or lacking. Adequate sampling as well as collaboration with a dermatopathologist in cases of suspected syringoma can help to reduce the susceptibility to commission bias and prevent histopathologic pitfalls and unwarranted surgical morbidity.

The Diagnosis: Glomangiomyoma

A punch biopsy of the right forearm revealed a collection of vascular and smooth muscle components with small and spindled bland cells containing minimal eosinophilic cytoplasm (Figure 1), confirming the diagnosis of glomangiomyoma. Immunohistochemical stains also supported the diagnosis and were positive for smooth muscle actin, desmin, and CD34 (Figure 2). Magnetic resonance imaging from a prior attempt at treatment with sclerotherapy demonstrated scattered vascular malformations with no notable internal derangement. There was no improvement with sclerotherapy. Given the number and vascular nature of the lesions, a trial of pulsed dye laser (PDL) therapy was administered and tolerated by the patient. He subsequently moved to a new military duty station. On follow-up, he reported no noticeable clinical improvement in the lesions after PDL and opted not to continue with laser treatment.

Glomangiomyoma is a rare and benign glomus tumor variant that demonstrates differentiation into the smooth muscle and potentially can result in substantial complications.¹ Glomus tumors generally are benign neoplasms of the glomus apparatus, and glomus cells function as thermoregulators in the reticular dermis.² Glomus tumors comprise less than 2% of soft tissue neoplasms and generally are solitary nodules; only 10% of glomus tumors occur with multiple lesions, and among them, glomangiomyoma is the rarest subtype, presenting in only 15% of cases.^2,3 The 3 main subtypes of glomus tumors are solid, glomangioma, and glomangiomyoma.4 Clinically, the lesions may present as small blue nodules with associated pain and cold or pressure sensitivity. Although there appears to be variation of the nomenclature depending on the source in the literature, glomangiomas are characterized by their predominant vascular malformations on biopsy. Glomangiomyomas are a subset of glomus tumors with distinct smooth muscle differentiation.⁴ Given their pathologic presentation, our patient’s lesions were most consistent with the diagnosis of glomangiomyoma.

The small size of the lesions may result in difficulty establishing a clinical diagnosis, particularly if there is no hand involvement, where lesions most commonly occur.² Therefore, histopathologic evaluation is essential and is the best initial step in evaluating glomangiomyomas.⁴ Biopsy is the most reliable means of confirming a diagnosis^2,4,5; however, diagnostic imaging such as a computed tomography also should be performed if considering blue rubber bleb nevus syndrome due to the primary site of involvement. Surgical excision is the treatment of choice after confirming the diagnosis in most cases of symptomatic glomangiomyomas, particularly with painful lesions.⁶

Neurilemmomas (also known as schwannomas) are benign lesions that generally present as asymptomatic, soft, smooth nodules most often on the neck; however, they also may present on the flexor extremities or in internal organs. Although primarily asymptomatic, the tumors may be associated with pain and paresthesia as they enlarge and affect surrounding structures. Neurilemmomas may occur spontaneously or as part of a syndrome, such as neurofibromatosis type 2 or Carney complex.⁷

Hereditary hemorrhagic telangiectasia (formerly known as Osler-Weber-Rendu syndrome) is an autosomal-dominant disease that presents with arteriovenous malformations and telangiectases. Patients generally present in the third decade of life, with the main concern generally being epistaxis.⁸

Kaposi sarcoma is a viral infection secondary to human herpesvirus 8 that results in red-purple lesions commonly on mucocutaneous sites. Kaposi sarcoma can be AIDS associated and non-HIV associated. Although clinically indistinguishable, a few subtle histologic features can assist in differentiating the 2 etiologies. In addition to a potential history of immunodeficiency, evaluating for involvement of the lymphatic system, respiratory tract, or gastrointestinal tract can aid in differentiating this entity from glomus tumors.9

Leiomyomas are smooth muscle lesions divided into 3 subcategories: angioleiomyoma, piloleiomyoma, and genital leiomyoma. The clinical presentation and histopathology will vary depending on the subcategory. Although cutaneous leiomyomas are benign, further workup for piloleiomyoma may be required given the reported association with hereditary leiomyomatosis and renal cell cancer (Reed syndrome).¹⁰

Imaging can be helpful when the clinical diagnosis of a glomus tumor vs other painful neoplasms of the skin is unclear, such as in blue rubber bleb nevus syndrome, angioleiomyomas, neuromas, glomus tumors, leiomyomas, eccrine spiradenomas, congenital vascular malformations, schwannomas, or hemangiomas.⁴ Radiologic findings for glomus tumors may demonstrate cortical or cystic osseous defects. Magnetic resonance imaging and ultrasonography can help provide additional information on the lesion size and depth of involvement.¹ Additionally, deeper glomangiomyomas have been associated with malignancy,² potentially highlighting the benefit of early incorporation of imaging in the workup for this condition. Malignant transformation is rare and has been reported in less than 1% of cases.⁶

Treatment of glomus tumors predominantly is directed to the patient’s symptoms; asymptomatic lesions may be monitored.⁴ For symptomatic lesions, therapeutic options include wide local excision; sclerotherapy; and incorporation of various lasers, including Nd:YAG, CO₂, and flashlamp tunable dye laser.^4,5 One case report documented use of a PDL that successfully eliminated the pain associated with glomangiomyoma; however, the lesion in that report was not biopsy proven.¹¹

Our case highlights the need to consider glomus tumors in patients presenting with multiple small nodules given the potential for misdiagnosis, impact on quality of life with associated psychological distress, and potential utility of incorporating PDL in treatment. Although our patient did not report clinical improvement in the appearance of the lesions with PDL therapy, additional treatment sessions may have helped,¹¹ but he opted to discontinue. Follow-up for persistently symptomatic or changing lesions is necessary, given the minimal risk for malignant transformation.⁶

The Diagnosis: Glomangiomyoma

A punch biopsy of the right forearm revealed a collection of vascular and smooth muscle components with small and spindled bland cells containing minimal eosinophilic cytoplasm (Figure 1), confirming the diagnosis of glomangiomyoma. Immunohistochemical stains also supported the diagnosis and were positive for smooth muscle actin, desmin, and CD34 (Figure 2). Magnetic resonance imaging from a prior attempt at treatment with sclerotherapy demonstrated scattered vascular malformations with no notable internal derangement. There was no improvement with sclerotherapy. Given the number and vascular nature of the lesions, a trial of pulsed dye laser (PDL) therapy was administered and tolerated by the patient. He subsequently moved to a new military duty station. On follow-up, he reported no noticeable clinical improvement in the lesions after PDL and opted not to continue with laser treatment.

Just over half of endoscopists use cold snare polypectomy to remove small polyps of less than 1 cm, despite recommendations from the U.S. Multisociety Task Force for its use in small lesions, shows new research presented this week in Vancouver at the annual meeting of the American College of Gastroenterology.

Polypectomy is a key part of colorectal cancer prevention, but endoscopists’ choice of polypectomy is a major factor in quality, and the characteristics of polypectomies in clinical practice are highly variable, said Seth D. Crockett, MD, of Oregon Health & Science University, Portland, in a presentation at the meeting.

Cold snare polypectomy is preferred for the removal of polyps less than 1 cm because of a high complete resection rate and a strong safety profile, compared to forceps and hot snares, which tend to be associated with high incomplete resection rates, inadequate histopathologic specimens, and/or complication rates. The adherence of endoscopists to the recommendations was not known until now, Dr. Crockett said.

This was a cross-sectional study of 1,589,499 colonoscopies that were conducted between 2019 and 2022 in patients (aged 40-80 years) who underwent a screening or surveillance colonoscopy in which at least one small polyp of less than 1 cm was removed. The final analysis included 3,082 endoscopists. Colonoscopies in which larger polyps were detected, or there was a confirmed case of cancer, were not included.

The mean endoscopist cold snare polypectomy rate (CSPR) was 51.2%, which was “lower than expected based on current guideline recommendations,” Dr. Crockett said.

Higher cold snare polypectomy rates were more common among specialists with training in gastroenterology, and more common among those who practiced in the Midwest (69%), as compared with practitioners in the Northeast who, at 40%, had the lowest rate. Colonoscopy volume, adenoma detection rate (ADR), serrated polyp detection rate (SDR), and cecal intubation rate (CIR), were all associated with a higher CSPR.

CSPR was more than 30% higher for endoscopists with an adenoma detection rate (ADR) of greater than 35%, compared with those with an ADR of less than 25% (58% vs. 27%, respectively; P < .0001). Lower usage rates among endoscopists with low ADRs could compound the problem of interval cancer if polyps are missed, Dr. Crockett said. Endoscopist serrated polyp detection rates of 7% of higher, cecal intubation rates of 95% or higher, and mean withdrawal times greater than 9 minutes were significantly associated with higher CSPR (P < .0001 for all).

The findings suggest a correlation between higher cold snare usage and improved quality metrics, such as adenoma detection rate and cecal intubation rate, said Jonathan A. Leighton, MD, of the Mayo Clinic, Scottsdale, Ariz., in an interview.

“I would agree with the authors that much of the focus on colonoscopy quality has been directed toward polyp detection, and little on the quality of polyp resection, which can be difficult to measure,” he said. “Their results suggest that cold snare polypectomy for removal of small polyps is currently underutilized, but as with any polypectomy, it is important that all of the dysplastic tissue is removed using good technique.”

The results were strengthened by the large sample size and high fidelity of measurements of polyp size, polypectomy tools, and quality measures. But more research is needed to determine the impact of polypectomy technique on outcomes of colonoscopy efficacy and safety. In terms of limitations, small polyps carry a relatively low risk of recurrence, and the associations between an endoscopist’s polypectomy practice and polyp recurrence, interval cancer, and adverse events were not examined, Dr. Crockett said.

The study was supported by a grant from the ACG. Dr. Crockett disclosed relationships with Carelon, Exact Sciences, Freenome, and Guardant.

The Food and Drug Administration has approved infliximab-dyyb (Zymfentra, Celltrion USA) for maintenance therapy in adults with moderately to severely active ulcerative colitis (UC) and Crohn’s disease (CD) after treatment with an intravenous infliximab product.

Infliximab-dyyb is a subcutaneous formulation of Celltrion’s infliximab. The FDA approval provides an alternative administration option for delivering the drug, which blocks the action of tumor necrosis factor alpha.

The new formulation was approved based on phase 3 pivotal trials that evaluated the safety and efficacy of infliximab-dyyb as maintenance therapy in patients with moderately to severely active UC (LIBERTY-UC) and CD (LIBERTY-CD).

In both 54-week trials, infliximab-dyyb demonstrated superiority to placebo in the primary endpoints of clinical remission (UC and CD) and endoscopic response (CD) when given as maintenance therapy after induction therapy with IV infliximab.

The overall safety profile of infliximab-dyyb was similar to that of the placebo during the maintenance period in both studies, with no new safety signals seen.

In the randomized, placebo-controlled, double-blind LIBERTY-UC study, 438 patients with moderately to severely active UC after induction therapy with IV infliximab were randomly assigned at week 10. The rate of clinical remission at week 54 was significantly greater with infliximab-dyyb (43.2%), compared with placebo (20.8%).

The most common adverse events were COVID-19, anemia, arthralgia, injection site reaction, increased alanine aminotransferase, and abdominal pain.

In the similarly designed LIBERTY-CD study, 343 patients with moderately to severely active CD after induction therapy were randomly assigned at week 10. At week 54, the clinical remission rate was greater with infliximab-dyyb (62.3%) than with placebo (32.1%).

In parallel, the endoscopic response rate at week 54 was also greater in the infliximab-dyyb arm than in the placebo arm (51.1% vs. 17.9%, respectively).

The safety profile during the maintenance phase was generally comparable between the two trial arms. The most common adverse events were COVID-19, upper respiratory tract infection, headache, injection site reaction, diarrhea, increased alanine aminotransferase, increased blood creatine phosphokinase, neutropenia, hypertension, urinary tract infection, dizziness, and leukopenia.

“As someone dedicated to improving the lives of patients with IBD, I am excited to see data supporting the efficacy and safety of a new formulation offering convenience and improved access to a well-known and proven drug,” Andres Yarur, MD, of Cedars-Sinai Medical Center, Los Angeles, said in a news release. 

The data “validate a convenient treatment option that could allow more patients in the United States to have greater control of their disease management,” added Jean-Frederic Colombel, MD, of Icahn School of Medicine at Mount Sinai, New York.

In the randomized, placebo-controlled, double-blind LIBERTY-UC study, 438 patients with moderately to severely active UC after induction therapy with IV infliximab were randomly assigned at week 10. The rate of clinical remission at week 54 was significantly greater with infliximab-dyyb (43.2%), compared with placebo (20.8%).

The most common adverse events were COVID-19, anemia, arthralgia, injection site reaction, increased alanine aminotransferase, and abdominal pain.

In the similarly designed LIBERTY-CD study, 343 patients with moderately to severely active CD after induction therapy were randomly assigned at week 10. At week 54, the clinical remission rate was greater with infliximab-dyyb (62.3%) than with placebo (32.1%).

In parallel, the endoscopic response rate at week 54 was also greater in the infliximab-dyyb arm than in the placebo arm (51.1% vs. 17.9%, respectively).

The safety profile during the maintenance phase was generally comparable between the two trial arms. The most common adverse events were COVID-19, upper respiratory tract infection, headache, injection site reaction, diarrhea, increased alanine aminotransferase, increased blood creatine phosphokinase, neutropenia, hypertension, urinary tract infection, dizziness, and leukopenia.

“As someone dedicated to improving the lives of patients with IBD, I am excited to see data supporting the efficacy and safety of a new formulation offering convenience and improved access to a well-known and proven drug,” Andres Yarur, MD, of Cedars-Sinai Medical Center, Los Angeles, said in a news release. 

The data “validate a convenient treatment option that could allow more patients in the United States to have greater control of their disease management,” added Jean-Frederic Colombel, MD, of Icahn School of Medicine at Mount Sinai, New York.

Adding enzalutamide (Xtandi) to androgen deprivation therapy (ADT) can extend metastasis-free survival (MFS) while maintaining quality of life in men with prostate cancer who have a high risk for biochemical recurrence, according to new research presented at the European Society of Medical Oncology meeting in Madrid.

At 5 years, nearly 90% of patients receiving enzalutamide plus the ADT leuprolide (multiple brands) were metastasis-free, while 80% of those receiving only enzalutamide and about 71% of those receiving only leuprolide were metastasis-free.

In a related analysis of patient-reported outcomes, investigators found that patients who received enzalutamide did not appear to have worse quality of life, compared with those treated with leuprolide alone.

“This could be a game-changer for one of the most common disease states in prostate cancer,” lead author Stephen Freedland, MD, director of the Center for Integrated Research in Cancer and Lifestyle at Cedars-Sinai Cancer, Los Angeles, said. The study was published online in the New England Journal of Medicine.

The results “confirm that in this population, as in men with more advanced stages, adding an androgen-receptor inhibitor [enzalutamide] increases the efficacy of androgen deprivation therapy,” Ana Aparicio, MD, from University of Texas MD Anderson Cancer Center, Houston, wrote in an accompanying editorial.

Standard care in this patient population relies on ADT to suppress testosterone, which would otherwise stimulate cancer cell growth. However, Dr. Freedland explained that “when you go on androgen deprivation therapy, the testosterone level in the blood is reduced but not completely eliminated. The concern is that the testosterone that remains may still be enough to stimulate tumor growth.”

Enzalutamide, an oral androgen receptor inhibitor, has already shown benefits in patients with metastases, and the current EMBARK trial explored whether the inhibitor can help men with earlier-stage disease who are at risk for metastases.

The findings from the phase 3 EMBARK trial, also published in NEJM Evidence, included 1,068 patients with prostate cancer at high-risk for biochemical recurrence. Patients, who had a median age of 69 years, spanned 244 sites across 17 countries.

Patients had a median prostate-specific antigen (PSA) doubling time of 4.9 months, with a median PSA of 5.2 ng/mL. Those with PSA doubling times of 9 months or less are considered at high-risk for biochemical recurrence and increased risk for death from prostate cancer.

Dr. Freedland and colleagues randomly assigned patients to three groups – enzalutamide 160 mg plus leuprolide every 12 weeks (n = 355), enzalutamide monotherapy (n = 355), and placebo plus leuprolide (n = 358). Patients received treatment for 38.7 months on average. 

At 5-years, 87.3% of men in the combination group were metastasis-free, compared with 80% in the monotherapy group and 71.4% in the leuprolide-only group. Compared with leuprolide alone, combining enzalutamide and leuprolide reduced the risk for metastasis or death by 58% (hazard ratio, 0.42; P < .001). And compared with enzalutamide monotherapy, the combination also significantly reduced the risk for metastasis or death, compared with leuprolide alone (HR, 0.63; P = .005).

The estimated proportion of patients free from PSA progression at 5 years was 97.4% in the combination group, 88.9% in the monotherapy group, and 70% in the leuprolide-only group.

At the time of data cutoff, 33 (9%) patients in the combination group, 42 (12%) in the monotherapy group, and 55 (15%) in the leuprolide-only group had died.

Nearly all (97%) patients experienced adverse events, most of which (86.4%) were treatment-related. Overall, 46.5% of patients in the combination group experienced a grade 3 or higher adverse event, compared with 50% in the enzalutamide monotherapy group and 42.7% in the leuprolide-only group. Clustered adverse effects occurred in 80% or more patients in all three groups, with the most common cluster combining fatigue, falls, fractures, hypertension, and musculoskeletal events.

The most common adverse events in the enzalutamide monotherapy group, occurring in at least 30% of patients, included gynecomastia, joint pain, hot flashes, and fatigue. Nipple pain and breast tenderness were also common side effects in the enzalutamide monotherapy arm – occurring in 15.3% and 14.4% of patients, respectively – compared with the combination (3.1% and 1.1%) or leuprolide-only (1.1% and 1.1%) groups.

However, Dr. Freedland explained, “our quality-of-life data show that you don’t need to sacrifice global quality of life to get these cancer benefits.”

Patient-reported outcomes from EMBARK revealed that both enzalutamide combination and monotherapy versus leuprolide alone preserved high health-related quality of life in patients with a high-risk for biochemical recurrence.

More specifically, Dr. Freedland and colleagues found no differences in the time to first clinically meaningful deterioration based on questionnaires that rated pain and functional status. Functional status measures included physical, social, and emotional well-being as well as symptom severity.

However, some differences emerged. For instance, time to confirmed clinically meaningful deterioration in physical well-being score was significantly shorter among patients receiving enzalutamide, compared with leuprolide monotherapy – 24.8 months in the combination group and 27.6 months in the enzalutamide-only group versus 49.8 months in the leuprolide-only group (HR, 1.41 and 1.35, respectively).

However, sexual activity appeared to be better preserved among patients receiving enzalutamide monotherapy, compared with leuprolide alone. The median time to confirmed clinically meaningful deterioration in sexual activity score was 5.6 months with enzalutamide monotherapy versus 3 months for leuprolide alone (HR, 0.76).

Given the slightly different side-effect profiles in the enzalutamide combination and monotherapy groups, Dr. Freedland noted that “it will be up to patients and care providers to decide which is the right choice for them. I think the important message is that both are a major step forward from the current standard of care, which is androgen deprivation therapy alone.”

Pedro Barata, MD, who was not involved in the research, also noted that “this is the first time we have seen this kind of results with a novel hormonal therapy without castration.”

Overall, “the findings of this trial confirm the benefit of adding a novel hormonal therapy such as enzalutamide earlier in the course of this disease,” said Dr. Barata, a medical oncologist and director of the Clinical Genitourinary Medical Oncology Research Program at University Hospitals Seidman Cancer Center, Cleveland.

However, he explained that many patients with “rising PSA and short doubling time are known to have metastatic disease as detected by PSMA PET and are already being offered a novel hormonal therapy combined with castration. Perhaps it will be an opportunity for men who don’t want to be castrated to be offered an anti–androgen-like enzalutamide by itself without castration in this patient population.”

Research was funded by Pfizer and Astellas Pharma, manufacturers of enzalutamide.

Approximately 1 in 40 women are carriers of single gene disorders that could manifest as pregnancy complications, based on data from more than 90,000 individuals.

Single gene disorders remain a leading cause of morbidity and mortality in newborns and children, but carrier screening for such disorders was limited until recent advances in DNA sequencing, wrote Vivienne Souter, MD, of Natera in Austin, Tex., and colleagues.

Identifying single gene disorders in carrier screening also includes the discovery of genetic variants that could affect the carrier parent during pregnancy, they said.

In a study published in Obstetrics and Gynecology, the researchers reviewed data from 91,637 female patients who underwent testing via a 274-gene carrier screening panel. The median age of the participants was 32.8 years, and approximately half were pregnant at the time of the testing.

Based on previously published reports, the researchers identified 12 genes with potential for carrier manifestations during pregnancy; of these, 9 had manifestations whether or not the fetus was affected by the genetic condition (ABCB11, COL4A3, COL4A4, COL4A5, DMD, F9, F11, GLA, and OTC) and 3 had manifestations only if the fetus was affected by the condition (CPT1A, CYP19A1, and HADHA).

Overall, 66% of the tests were positive for at least one of the 274 genes; the frequency of potentially pathogenic variants for the 12 genes that could manifest as complications during pregnancy ranged from 1 in 117 individuals for the F11 gene to 1 in 8,331 for the OTC gene.

A total of 2.3% of the participant tests were associated a pathogenic or likely pathogenic variant in at least 1 of the 12 genes, which accounted for 3.5% of all positive samples, and 2.0% were identified as carriers for 1 of the 9 genes that could affect women during pregnancy regardless of fetal genetic status.

“People of Ashkenazi Jewish heritage were over-represented in the carrier group, representing 6.0% of carriers but only 1.9% of the entire study cohort,” the researchers noted.

Manifestations related to the 12 genes included cardiomyopathy, hemorrhage, gestational hypertensive disorders, cholestasis of pregnancy, acute fatty liver, hyperammonemic crisis, and maternal virilization.

“The reported incidence of pregnancy complications in carriers ranged from 10% to 62% depending on the gene involved, but information was limited for most of the conditions,” and published literature identified management recommendations for 11 of the 12 genes, the researchers wrote.

The findings were limited by several factors including the use of cases received by the laboratory, which might have yielded more women with above-average risk because of family history, the researchers noted. Other limitations included a lack of data on further evaluation or counseling after the screening, and the lack of separation of the results according to the specific variant, they said. Also, the study population was limited to those who had access to carrier screening, and may not be generalizable to the population at large.

However, the results support the value of carrier screening, and pretest counseling should inform individuals of the potential identification of genes that might increase their risk of complications during pregnancy, the researchers said.

“Obstetric care professionals should also be aware that carrier status for certain conditions can be important for risk assessment and management in pregnancy,” and post-test genetic counseling, follow-up testing, and clinical management can help reduce risks, which could potentially be identified prior to pregnancy, they concluded.

However, the results support the value of carrier screening, and pretest counseling should inform individuals of the potential identification of genes that might increase their risk of complications during pregnancy, the researchers said.

“Obstetric care professionals should also be aware that carrier status for certain conditions can be important for risk assessment and management in pregnancy,” and post-test genetic counseling, follow-up testing, and clinical management can help reduce risks, which could potentially be identified prior to pregnancy, they concluded.

The study was funded by Natera. Dr. Souter is an employee of Natera.

CARLSBAD, CALIF. – According to Delphine J. Lee, MD, PhD, some patients report that their dermatologists tell them there are no effective treatments for vitiligo.

However, this is not supported by the ongoing level of research on vitiligo, with more than 100 randomized controlled trials published over the last 5 years, Dr. Lee, chief of dermatology at Harbor-UCLA Medical Center, Los Angeles, said at the annual symposium of the California Society of Dermatology & Dermatologic Surgery. And, in 2022, ruxolitinib cream became the first FDA-approved treatment for vitiligo. “There’s a lot of research happening now, and I’m pleased to say that despite the fact that some of these medications are not all brand new and exciting, they’re still new in that we have new evidence for them,” she said. “Of the 100 randomized, controlled trials, UV therapy remains a strong part of our armamentarium.”
 

Stabilizing disease

Dr. Lee underscored the importance of stabilizing existing vitiligo and arresting progressive disease, which may be indicated by four key signs: koebnerization; trichrome lesions; inflammation, which can appear as erythema, scaling, and pruritus; and confetti-like macules that are typically 1 mm to 5 mm in size. Key principles of vitiligo treatment are to stop immune destruction and to stimulate melanocyte differentiation, migration, and melanin production, which is “probably why phototherapy is so important and helpful,” she said.

Managing patients’ expectations is also important, added Dr. Lee, who shows patients photos from published clinical trials “so they can see what excellent repigmentation really means.”
 

Dexamethasone vs. mycophenolate

In a randomized, controlled trial published in 2021, researchers compared dexamethasone oral mini-pulse (OMP), 2.5 mg, on two successive days a week, with oral mycophenolate mofetil, 500 mg b.i.d., up to 2 g every day, for 180 days as a stabilizing treatment for patients with progressive, nonsegmental vitiligo, with 90 days of treatment-free follow-up. Assessments included the vitiligo disease activity (VIDA) score, the number of new lesions in the past 30 days, and the Vitiligo Area Scoring Index (VASI). Arrest of disease progression was defined as the absence of any new lesions in the previous 30 days.

Over the treatment and follow-up period, both groups showed a significant trend for reduction in VIDA and in the number of new lesions in the previous 30 days, compared with baseline (P < .001). The difference between VASI at baseline and VASI at 180 and at 270 days was not significant in both groups.

Adverse side effects reported with dexamethasone included acne, weight gain, headache, insomnia, and menstrual irregularity. “The misconception is that because we only give patients a tiny dose of steroids – 2.5 mg two days per week – that they aren’t going to have any side effects,” Dr. Lee commented. “But in fact, they do.” The most common side effects with mycophenolate were nausea and diarrhea. Two patients on mycophenolate discontinued treatment: one for leukopenia and one for transaminitis, but both conditions resolved after treatment was stopped.

The researchers concluded that both dexamethasone OMP and mycophenolate mofetil halt actively spreading vitiligo. “Relapse occurred earlier with mycophenolate, and the relapse rate was higher than with dexamethasone OMP, but this was not statistically significant,” said Dr. Lee, who also leads an immunology research team at The Lundquist Institute at Harbor-UCLA Medical Center.

Other vitiligo treatment options she discussed included the following:

Betamethasone OMP and oral azathioprine. In a comparative study, researchers compared betamethasone OMP with oral azathioprine in arresting disease progression and inducing repigmentation in adults with vitiligo. Significantly more patients in the betamethasone OMP group achieved arrest of progression at 2 months than those in the azathioprine group, but at 6 months the difference was not significant. At 6 months, of the 19 patients who completed 6 months of betamethasone OMP, 2, 2, and 9 patients had more than 20%, 10%-20%, and 5%-10% repigmentation, respectively; and of the 18 patients who completed 6 months of azathioprine, 2 patients had 10%-20% repigmentation, with the remaining patients having no repigmentation or less than 5% repigmentation.

One patient in the azathioprine group developed acute pancreatitis but none developed transaminitis or leukopenia. “Azathioprine is another agent to add to our toolbox,” Dr. Lee said of the study findings. “Both betamethasone OMP and daily azathioprine are effective” in halting disease progression.

Low-dose cyclosporine. In a comparative study, 50 patients with active vitiligo were randomized into two groups: 25 to dexamethasone OMP 2.5 mg on two consecutive days/week for 4 months, and 25 to cyclosporine 3 mg/kg per day for 4 months, stopped treatment, and were then followed up for another 2 months. After 6 months, 84% of patients in the dexamethasone OMP group and 88% of patients in the cyclosporine group achieved arrest of disease progression (P = 1.00), but the mean time to achieve that endpoint was shorter for those in the cyclosporine group, compared with those in the dexamethasone OMP group (a mean of 3.92 weeks vs. 4.12 weeks, respectively; P = .01).

The list of adverse side effects for cyclosporine was “quite lengthy compared to the usual you would expect for dexamethasone,” said Dr. Lee, who was not involved with the study. “This is something we want to take seriously and discuss with our patients. Still, I would say that low-dose cyclosporine is another possibility to add to our toolbox.”

Phototherapy combined with polypodium leucotomos. Dr. Lee highlighted a randomized, controlled trial in which 21 patients with generalized vitiligo received narrow band (NB)-UVB phototherapy plus polypodium leucotomos extract (480 mg b.i.d.) and 21 patients received NB-UVB phototherapy plus placebo. After 6 months of treatment, patients in the NB-UVB plus oral polypodium leucotomos extract group had a better response rate, compared with those in the NB-UVB plus placebo group (47.8% vs. 22%). “We know from studies of polypodium leucotomos that it seems to have an impact on adaptive immunity as well as helps to decrease oxidative stress, so that may help with melanocyte stability in vitiligo,” said Dr. Lee, who was not affiliated with the study. “As with all treatments, the head and neck is very responsive to this combination treatment. The next most responsive area would be the trunk, followed by the extremities, and hands, and feet.”
 

Topical treatments

What about topical options for vitiligo? In a randomized, double-blind, comparative study, researchers evaluated the efficacy and safety of combination treatment with 308-nm excimer light and topical calcipotriol or topical clobetasol ointment for acral vitiligo. Combination treatment (excimer light and topical medication) was applied in the first 12 weeks, followed by topical medication alone for 12 weeks. Calcipotriol 0.005% ointment was applied on one hand vs. clobetasol propionate 0.05% ointment on the other for 24 weeks.

Of the hands treated with excimer light and calcipotriol, 7.7% achieved excellent repigmentation at the end of the combination treatment period and 23% achieved good to excellent improvement after 12 weeks of calcipotriol monotherapy. More than 85% and 77% of the hands treated with calcipotriol-based and clobetasol-based regimens showed some repigmentation at the end of the study, respectively (P < .05). However, no significant difference was found between the two treatments. “The evaluation from study participants was similar in that they felt that there was clearly a difference from baseline, but there was no difference across the two-hand therapy,” Dr. Lee said.

Adverse side effects included the development of blisters in some of patients who received clobetasol. “The take-home here is that you get excellent repigmentation with calcipotriol, though it’s a small percentage, 7.7%,” Dr. Lee said. “No excellent repigmentation was observed with excimer light and topical clobetasol. These data support two possible topical regimens that could be added to phototherapy or excimer light therapy to improve results.”

In another study of 42 patients, researchers compared twice-daily tacrolimus 0.1% ointment with vehicle for facial vitiligo through 24 weeks of intervention and 24 weeks of follow-up. The researchers defined treatment success as a change of 75% or greater in repigmentation of the target lesion between baseline and week 24, as measured by computer imaging software.

They found that 65% of tacrolimus-treated patients achieved therapeutic success, compared with none of the vehicle-treated patients at week 24 (P < .0001). “Tacrolimus is thought to be an old drug, but it does deserve to have continued proper study based on much anecdotal evidence I hear,” Dr. Lee said. “There was also efficacy over vehicle during the 24 weeks of follow-up. I find that tacrolimus works very well on the face. I’ve had very good results in children.”

Another topical option is the cream formulation of the JAK inhibitor ruxolitinib (Opzelura), approved in 2022 for the treatment of nonsegmental vitiligo in patients ages 12 and older, the first FDA-approved treatment for vitiligo. “As with the tacrolimus study, there are patients who achieve 100% repigmentation [with ruxolitinib], but others who may not,” Dr. Lee said. In addition, she noted that the combination of JAK inhibitors with phototherapy is emerging as another possible treatment choice, referring to a recently published systematic review suggesting that concurrent UVB phototherapy appears to improve efficacy of JAK inhibitors for vitiligo.

Dr. Lee reported having no relevant financial disclosures.

GLASGOW – Three-quarters of women going through perimenopause and menopause experience unexpected distressing, debilitating, and embarrassing symptoms but often fail to receive appropriate treatment, a large U.K.-based survey found. 

“For too long, many people have thought of menopause as just hot flashes and vaginal dryness. But we know hormones work all over our body, so there are many symptoms beyond that,” said Daniel Reisel, MBBS, PhD, a gynecologist at University College London, who presented the survey findings at the 2023 annual meeting of the Royal College of General Practitioners.

Primary care physicians in the United Kingdom have seen an increase in cases of women presenting with symptoms associated with menopause at a time when the country’s Parliament is debating whether all women should have a menopause check-up in their early 40s, he said.  

Still, only around 14% of menopausal women in the United Kingdom are prescribed hormone replacement therapy (HRT), despite national and international guidelines clearly stating the benefits of the treatment generally outweigh the risks.

Louise Newson, MBChB, who runs the U.K.’s largest menopause clinic, said many women with symptoms of menopause feel the medical system “gaslights” them – dismissing their concerns as trivial or even fabricated.

In her clinic, she typically sees many women with poor sleep, as well as muscle and joint pains. “Yet [when they visit their GPs], they are incorrectly told that it can’t be hormones because they’re still having periods,” she said.
 

Prescribed antidepressants often precede HRT

The new study sought to learn what women knew and experienced with respect to menopause symptoms and what they thought was important.

Of the 5,744 women who responded to the survey, 79.4% were aged 40-60 years and 84.6% were White. “The survey respondents were not different from the distribution of ethnicities we see in NHS menopause care,” said Dr. Reisel, adding that “the barriers are greater for women in poorer areas and for those who are non-White.”

A total of 30.4% had two to five hospital consultations before the health care professional considered that symptoms were related to changing hormone levels; 38.5% were offered antidepressants before HRT. Nearly all (94.6%) said they had experienced negative mood changes and emotions since becoming perimenopausal or menopausal; of these, 19.1% were formally diagnosed with depression or a mood disorder.

“This all just highlights the frustrations I feel around menopause care,” Dr. Newson said. “Women are often not given the tools to properly understand what’s going on and then they don’t ask for the right treatment, and many are given antidepressants. It’s still medicalizing the menopause but in a different way.”
 

Education gap

The researchers also asked women if they had experienced any surprising or unexpected symptoms since becoming perimenopausal or menopausal. To this question, 74.2% said they had. Joint pain was the most common unexpected issue (34%), followed by dry eyes (26%), heart palpitations (25%), and hair issues such as dryness, thinning, and loss (20%).

Dr. Reisel said words used to describe these symptoms in free text responses included “distressing,” “debilitating,” “depressing,” and “embarrassing.”

“When an early-50s woman comes to the GP with dry eyes, joint pain, or recurrent urinary tract infections, for example, before prescribing ibuprofen, or antibiotics, GPs should consider replacing a woman’s hormones and then see what is left in terms of symptoms,” he said.

Cognitive problems and negative mood changes also are common and often overlooked, Dr. Reisel noted. “We often see striking improvements in mood and cognition in women who are prescribed testosterone for low libido, yet symptoms in these areas are not currently an indication to start treatment,” he said. “Data from Newson Health show that 18% have suicidal thoughts in the past 2 weeks, and not many people think about this.”

Much of this lack of understanding around unexpected symptoms relates to a lack of awareness and education. “It goes back to primary and secondary school, and more broadly, these issues are not often talked about in society,” he said.  

Dr. Reisel also noted that language and cultural barriers often stand in the way. “Many cultures don’t discuss menopause and hormone health in general at all. For example, in Bengali, spoken by 300 million people, there is no word in for menopause. So many women are gaslighted when they try and describe their symptoms, or they’re simply just unaware.”

Dr. Reisel and Dr. Newson reported no relevant financial relationships.

GLASGOW – Three-quarters of women going through perimenopause and menopause experience unexpected distressing, debilitating, and embarrassing symptoms but often fail to receive appropriate treatment, a large U.K.-based survey found. 

“For too long, many people have thought of menopause as just hot flashes and vaginal dryness. But we know hormones work all over our body, so there are many symptoms beyond that,” said Daniel Reisel, MBBS, PhD, a gynecologist at University College London, who presented the survey findings at the 2023 annual meeting of the Royal College of General Practitioners.

Primary care physicians in the United Kingdom have seen an increase in cases of women presenting with symptoms associated with menopause at a time when the country’s Parliament is debating whether all women should have a menopause check-up in their early 40s, he said.  

Still, only around 14% of menopausal women in the United Kingdom are prescribed hormone replacement therapy (HRT), despite national and international guidelines clearly stating the benefits of the treatment generally outweigh the risks.

Louise Newson, MBChB, who runs the U.K.’s largest menopause clinic, said many women with symptoms of menopause feel the medical system “gaslights” them – dismissing their concerns as trivial or even fabricated.

In her clinic, she typically sees many women with poor sleep, as well as muscle and joint pains. “Yet [when they visit their GPs], they are incorrectly told that it can’t be hormones because they’re still having periods,” she said.
 

Prescribed antidepressants often precede HRT

The new study sought to learn what women knew and experienced with respect to menopause symptoms and what they thought was important.

Of the 5,744 women who responded to the survey, 79.4% were aged 40-60 years and 84.6% were White. “The survey respondents were not different from the distribution of ethnicities we see in NHS menopause care,” said Dr. Reisel, adding that “the barriers are greater for women in poorer areas and for those who are non-White.”

A total of 30.4% had two to five hospital consultations before the health care professional considered that symptoms were related to changing hormone levels; 38.5% were offered antidepressants before HRT. Nearly all (94.6%) said they had experienced negative mood changes and emotions since becoming perimenopausal or menopausal; of these, 19.1% were formally diagnosed with depression or a mood disorder.

“This all just highlights the frustrations I feel around menopause care,” Dr. Newson said. “Women are often not given the tools to properly understand what’s going on and then they don’t ask for the right treatment, and many are given antidepressants. It’s still medicalizing the menopause but in a different way.”
 

Education gap

The researchers also asked women if they had experienced any surprising or unexpected symptoms since becoming perimenopausal or menopausal. To this question, 74.2% said they had. Joint pain was the most common unexpected issue (34%), followed by dry eyes (26%), heart palpitations (25%), and hair issues such as dryness, thinning, and loss (20%).

Dr. Reisel said words used to describe these symptoms in free text responses included “distressing,” “debilitating,” “depressing,” and “embarrassing.”

WASHINGTON – In psoriatic disease, psoriatic arthritis (PsA) remains one of the greatest unmet needs, with the transition from cutaneous psoriasis poorly understood, diagnosis challenging, and therapeutic accomplishments trailing far behind advances for skin disease. However, leading researchers in rheumatology and dermatology believe that they’re turning the corner toward a day when therapies are phenotype-targeted and diagnosis can be made early and treatment begun well before inflammation worsens and pain and joint damage ensue.

“The challenge right now is that we don’t understand the discrete and overlapping endotypes that underlie the phenotypes or domains” of PsA, said Christopher Ritchlin, MD, MPH, professor of medicine in the division of allergy/immunology and rheumatology and the Center of Musculoskeletal Research at the University of Rochester (N.Y.), who spoke about PsA at the annual research symposium of the National Psoriasis Foundation.

A deep dive into the tissue

Dr. Ritchlin is among those rheumatology clinician-researchers who advocated early on for a “domain” approach to the diagnosis and management of PsA – that is, consideration of the key domains of peripheral arthritis, axial disease, enthesitis, dactylitis, and skin and nail psoriasis.

The approach is an especially important part of treatment recommendations from the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis. But while interventions can be tailored to some extent to these domains, or phenotypes, there are limitations without an understanding of the different pathophysiology and mechanisms driving the heterogeneity in tissue involvement.

Dr. Ritchlin draws inspiration from pulmonology, which subtyped asthma into various phenotypes (for example, eosinophilic, allergic, intrinsic, exercise-induced) and “drilled down” on understanding underlying mechanisms to guide more specific treatment. Similar phenotype-endotype research has been done for chronic obstructive pulmonary disease, he said at the meeting, pointing to a phase 3 randomized controlled trial, published in the New England Journal of Medicine, that found dupilimab (Dupixent) was effective for patients with COPD who had type 2 inflammation as indicated by elevated eosinophil counts.

“It’s a beautiful example of how to define an endotype from a phenotypic biomarker and then use a specific intervention to improve outcomes,” Dr. Ritchlin said. “We need to do this for psoriasis and PsA.”

The ELLIPSS project will utilize the host of -omics tools and technologies (for proteomics, metabolomics, and genomics, for instance) that are making it increasingly possible to dissect the heterogeneity of single diseases and achieve more precision with treatments.

Researchers will collect blood samples and skin and/or synovial tissue biopsies from cohorts of patients with psoriasis and PsA who are treatment naïve as well as patients who are treated with a biologic or DMARD (looking at responders and non-responders). They’ll also study a cohort of psoriasis patients who may be “on a transition pathway” for PsA based on risk factors such as family history, nail psoriasis, scalp psoriasis, and body surface area greater than 5%.

Patients in all cohorts will represent distinct synovio-entheseal domains of PsA and the heterogeneity of psoriasis (for example, plaque, general, pustular, palmoplantar) and will be followed longitudinally.

With regards to PsA, one goal is to “find new pathways in the joint, then find surrogate markers in the blood that we can use to help mark particular subphenotypes [that will be identified through deep phenotyping],” Dr. Ritchlin said in an interview after the meeting. “This will lead us hopefully to a more precision-based approach.”

The ELLIPSS team joins other researchers who have been studying rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) in an earlier iteration of the AIM program, and that will continue this work. Research on RA has thus far elucidated T-cell subsets in the rheumatoid synovium, as well as interactions of mesenchymal cells with the endothelium, for instance, and led to the identification of key molecules such as granzyme A that weren’t previously known to be involved in RA pathogenesis, Dr. Ritchin said in the interview. The current AIM work also includes Sjögren’s disease.
 

Finding biomarkers, diagnostic signatures

The psoriasis-PsA team has the advantage today of being able to utilize a new technology called spatial transcriptomics, which takes transcriptomics (RNA) from the single-cell level to the tissue level, enabling a look at how disease is affecting cellular organization/tissue architecture, gene activity, and cellular signaling within tissues. “It’s a huge advance in technology,” said Dr. Ritchlin. “We can actually see how the cells are interacting in the synovium [and other tissues].”

A paper published in Science Immunology and discussed at the NPF meeting demonstrates the power of special transcriptomics for learning about the skin. Dr. Scher, Dr. Ritchlin, first authors Rochelle L. Castillo, MD, and Ikjot Sidhu, MS, and other co-investigators reported a “dynamic re-organization of the immune milieu and fibroblasts in PsO lesional and non-lesional skin,” the presence of B cells in lesioned skin, and cellular organization/ecosystems that vary occurring according to clinical severity, among other findings.

Dr. Scher is using the tool for his NPF-funded diagnostic test research and as part of his work at NYU Langone for the ELLIPPS project. Among his goals: To “discover new cell populations in the microenvironment and study how they interact with each other, then compare those cells between psoriasis and PsA patients to first understand if they’re any different,” he explained after the meeting. Researchers can then investigate the synovial tissue, comparing cell populations and interactions in both compartments and looking for any shared markers/cytokines/proteins, he said.

Multiomics research, meanwhile, is showing that a test for early PsA detection could potentially combine clinical parameters with integrated multi-omic markers into a “diagnostic signature” of sorts.

At the meeting, Vinod Chandran, MD, PhD, a rheumatologist at the University of Toronto who also has an NPF PsA diagnostic test grant, said that his multi-omics analysis of blood samples from patients with psoriasis and PsA has identified signatures with a “high discriminatory value” and that certain metabolic pathways appear to play “a central role in the development and differentiation of PsA.” (Validation in other cohorts and economic analyses are ongoing, Dr. Chandran said. Low-cost alternatives that can be applied broadly in the clinic will need to be pursued, Dr. Scher said.)

Eyes on combination therapy

“The likelihood that all patients will respond to one biologic is very low in PsA, so we’ve been thinking about combination therapy for some time,” Dr. Ritchlin said at the meeting. “I think [dual inhibition] is coming.”

Safety has been the concern, but a phase 2 trial published this year compared a combination of IL-23 and TNF inhibition (guselkumab [Tremfya] plus golimumab [Simponi]) with monotherapy of both biologics in patients with ulcerative colitis and showed that the combination safely drove synergistic restoration of a normal epithelium and mucosal healing, he said.

A phase 2 trial in PsA, designed by Dr. Ritchlin and Dr. Scher and named AFFINITY, will study the safety and efficacy of the same combination of IL-23 and TNF blockade, compared with guselkumab (IL-23 inhibition) alone. The trial is currently completing enrollment of patients who have failed one or two anti-TNF agents.

In the meantime, combination therapy is being employed in clinics for “PsA patients who’ve been channeled through multiple biologics and are still not responding ... when [physicians] feel they’re forced to, not right away,” Dr. Ritchlin said in an interview after the meeting. “As we get a better understanding [through clinical trials], it might be something you’ll see earlier in the treatment process.”

It is wise, Dr. Ritchlin said, to devote more time to addressing “extra-articular traits” (for example, obesity, diabetes, uveitis, colitis, centralized pain) and treatable lifestyle/behavioral risk factors (for example, smoking, exercise, nutrition, adherence to therapy, social support) that can contribute to PsA and treatment nonresponse. He calls this the “treatable traits” strategy.

In practice, “there’s a big focus on inflammation and immune dysfunction, but the problem is, there are other factors involved in nonresponse, and I think ‘treatable traits’ gets to those,” Dr. Ritchlin said after the meeting. Rheumatologists and dermatologists lack time and alliances to address these issues, but “if we can find ways to do it, I think we’ll have improved outcomes.”

Dr. Ritchlin, Dr. Chandran, and Dr. Liao reported no relevant disclosures. Dr. Scher reported ties to Janssen, Pfizer, Sanofi, UCB, and Bristol-Myers Squibb.

It is wise, Dr. Ritchlin said, to devote more time to addressing “extra-articular traits” (for example, obesity, diabetes, uveitis, colitis, centralized pain) and treatable lifestyle/behavioral risk factors (for example, smoking, exercise, nutrition, adherence to therapy, social support) that can contribute to PsA and treatment nonresponse. He calls this the “treatable traits” strategy.

In practice, “there’s a big focus on inflammation and immune dysfunction, but the problem is, there are other factors involved in nonresponse, and I think ‘treatable traits’ gets to those,” Dr. Ritchlin said after the meeting. Rheumatologists and dermatologists lack time and alliances to address these issues, but “if we can find ways to do it, I think we’ll have improved outcomes.”

Dr. Ritchlin, Dr. Chandran, and Dr. Liao reported no relevant disclosures. Dr. Scher reported ties to Janssen, Pfizer, Sanofi, UCB, and Bristol-Myers Squibb.
