Cardiologists can perform stroke thrombectomy to fill ‘unmet need’
Cardiologists experienced in cardiac interventions can competently perform stroke thrombectomy after a short period of training, with outcomes comparable to those achieved by neuroradiology centers, a new study suggests.
“Using interventional cardiologists in this way will help address the huge unmet need for stroke thrombectomy that currently exists,” senior author Petr Widimsky, MD, said in an interview.
Although this may be a feasible way forward in Europe, there is strong opposition to such a proposal from U.S. neurointerventionalists.
The study, published in the April 12 issue of JACC: Cardiovascular Interventions, describes the establishment of a stroke thrombectomy program in University Hospital Kralovske Vinohrady, a large tertiary hospital in Prague, Czech Republic.
The hospital did not have a neurointerventional program until 2012 when a joint program was started involving an experienced team of cardiologists, angiologists, and one interventional radiologist who trained the cardiologists on the thrombectomy procedure.
The current paper reports on the outcomes of the 333 patients with large vessel occlusion stroke treated under this program between October 2012 and December 2019.
The decision to perform catheter-based thrombectomy was made by a neurologist and was based on acute stroke clinical symptoms and CT angiographic findings.
Results show that functional clinical outcomes, assessed via the Modified Rankin Scale (mRS) score at 3 months, did not vary significantly across years 2012 to 2019, with a favorable outcome (mRS 0 to 2) achieved in 47.9% of patients.
Symptomatic intracerebral hemorrhage occurred in 19 patients (5.7%) and embolization in a new vascular territory occurred in 6 patients (1.8%), outcomes similar to those of neuroradiology centers.
The desired clinical results were achieved from the onset of the program, without any signs of a learning curve effect, they reported.
“These findings support the potential role of interventional cardiac cath labs in the treatment of acute stroke in regions where this therapy is not readily available due to the lack of neurointerventionalists,” the authors concluded.
“Our main message is that our results were excellent from the beginning,” Dr. Widimsky said. “When centers prepare properly, they can achieve excellent results from the beginning with cardiologists who are experienced in interventional procedures and who have spent sufficient time learning about the brain.”
The authors noted that despite thrombectomy being an extremely beneficial treatment for severe stroke, many eligible patients remain untreated, largely because of a lack of neurointerventionalists in many regions worldwide. They estimate that about 15% of all stroke patients are eligible for thrombectomy but only around 2% of stroke patients in Europe actually receive such treatment.
Dr. Widimsky, an interventional cardiologist, first thought of the idea of using cardiologists to perform stroke thrombectomies after a good friend and colleague suffered a severe stroke in 2010.
“This made us realize that our hospital needed to be more active in the stroke field,” he said. “We decided that we needed to start doing stroke interventions.”
But the major problem was the lack of neurointerventionalists.
“There are not enough neurointerventionalists in Europe. Interventional cardiologists can perform thousands of procedures every year whereas a neurointerventionalist will at best perform hundreds a year. It is quicker and simpler to train the cardiologist to do it,” Dr. Widimsky said.
They hired one neurointerventionalist to lead the program. “He was our tutor, he taught us his skills,” Dr. Widimsky said. “The cath lab is open 24/7, but if we only have one neurointerventionalist we cannot offer a 24/7 service for stroke thrombectomy. But if we merge with cardiology then we can,” he added.
Their hospital is a very busy center for myocardial infarction, percutaneous coronary intervention, and carotid stenting, he noted. “It is not difficult to make the step from that to stroke thrombectomy. Interventional cardiologists are used to performing carotid and coronary artery stenting. Stroke thrombectomy is a similar technique. The thrombectomy procedure is different from coronary angioplasty but it is not more difficult. Actually, I think coronary angioplasty can be more difficult.”
Dr. Widimsky explained that cardiologists need to learn about the brain anatomy and physiology and learn the stroke imaging techniques. “I spent 1 month in the U.S. learning stroke interventions working with simulators,” he said. “I think interventional cardiologists can learn what they need to know in about 6 months. I would recommend they should watch about 50 procedures and perform at least 25 under supervision.”
He said this model is the way forward and hopes it will become routine. Thrombectomy is “tremendously effective” in improving outcomes in severe strokes, with a number needed to treat (NNT) of just 2.6 to prevent long-term disability in one patient, he said, while other procedures can have NNTs of 50 or more.
“But millions of patients with acute severe stroke are not getting this life-changing treatment,” he added. “We must do everything we can to make this service available to as many patients as possible.”
Dr. Widimsky acknowledges that there has been opposition to this idea from the neurointerventionalist professional bodies but this has lessened recently, at least in Europe. And a program that allows interventionalists with experience in extracranial carotid and vertebral endovascular procedures to “fast-track” technical training has now been proposed.
“There is an enormous unmet need for stroke thrombectomy in Europe, with some countries needing to increase the number of procedures done by 10 or 20 times. These include the U.K., Sweden, Italy, Spain, and Portugal. This cannot be done without cardiology,” Dr. Widimsky said.
Editorial strongly supportive
An accompanying editorial strongly endorses the idea of using interdisciplinary teams to deliver high standard stroke care.
Marius Hornung, MD, and Horst Sievert, MD, from CardioVascular Center Frankfurt (Germany), point out that many experienced cardiologists are trained in performing carotid artery interventions and are therefore experienced in accessing the supra-aortic arteries.
“To be able to guarantee optimized stroke therapy as soon as possible, disputes over competence among the individual medical societies involved must be ended,” they wrote.
They advocate for the creation of interdisciplinary teams, with diagnostics, patient selection, and follow-up care remaining the core competencies and tasks of neurology; in addition, they call for appropriately trained and experienced physicians – regardless of their specialties – performing acute stroke interventions and endovascular thrombectomy.
“Such a network must be installed as soon as possible to fulfill the mantra ‘time is brain’ ... and not losing unnecessary time to patient transfer, or continuing to offer only the second-best therapy,” they concluded.
Opposition in the United States
Dr. Widimsky explained that this proposal may not be so applicable to the United States, where the need for more clinicians capable of performing stroke thrombectomies does not appear to be as critical, possibly because vascular neurosurgeons as well as neuroradiologists are qualified to undertake these procedures.
In an interview, J. Mocco, MD, director of the cerebrovascular center, department of neurological surgery, at Mount Sinai Health System, New York, confirmed that this was the case.
“There is no legitimate data to support the claim that there is a lack of an adequate workforce to provide stroke thrombectomy, at least in the U.S.,” he said, adding that, rather, the primary limitation to patient access is a lack of adequate systems of care. “We should learn from the trauma model, which is strongly evidence based, and provide emergency stroke care in a similarly regionalized manner.”
Dr. Mocco, vice president of the Society of NeuroInterventional Surgery, was not impressed with the current study.
“This paper is a retrospective, single-center, unadjudicated, nonindependent assessor case series and therefore, as the authors acknowledge in the limitations section of their paper, it is invalid to compare these data to the results from high-quality, prospective, core-lab, and independent assessor adjudicated randomized trials,” he said. “The supposition that this trial provides evidence that the reported model should be widely considered lacks scientific rigor.”
Furthermore, “the interventional cardiology literature is replete with data regarding the importance of technical expertise and content knowledge,” he added. “Why would that community now propose that such expertise and knowledge is not necessary for the brain?”
Dr. Mocco argues that the concept that interventional cardiologists should be fast-tracked to perform stroke interventions because they use similar tools, navigate blood vessels, and are comfortable working in critical situations, does not hold up.
“Liver surgeons and brain surgeons are both familiar with tissue manipulation, are used to operating in critical situations, and use cautery, scissors, and scalpels; but no one would argue that a brain surgeon should be fast-tracked to perform liver surgery, or vice versa.”
He added: “Stroke patients do not have the luxury of choosing the physician who provides their thrombectomy. We should do everything reasonable to ensure that our systems of care are organized so that these vulnerable patients are treated by physicians who have appropriate knowledge and expertise.”
This study was supported by the Charles University Research program. The authors and editorialists have disclosed no relevant financial relationships.

Pneumonia risk soars in heart failure patients, especially HFpEF
Patients with heart failure get pneumonia at a rate almost three times greater than expected and, once they do get pneumonia, have about a fourfold greater risk of death, investigators for a retrospective analysis of 13,000 patients from two landmark randomized HF trials have found.
The investigators also found that HF patients with preserved ejection fraction (HFpEF) are at the highest risk of developing pneumonia. The findings underscore the importance of patients with HF getting a pneumonia vaccination, they found.
The analysis showed that 6.3% of patients in the PARADIGM-HF trial and 10.6% of those in the PARAGON-HF trial developed pneumonia, reported the study authors, led by John J.V. McMurray, MD, of the British Heart Foundation Cardiovascular Research Center at the University of Glasgow in Scotland (J Am Coll Cardiol. 2021;77:1961-73).
“The main reason for doing this study was the fact that many heart failure patients are not vaccinated, as they should be, against pneumonia – both pneumococcus and influenza vaccination,” Dr. McMurray said in an interview. “We wanted to document the frequency and consequences of pneumonia in patients with heart failure to help highlight this deficiency in care.”
Dr. McMurray said he believes this is the first study to document the incidence of pneumonia and pneumonia-related outcomes according to the two major ejection fraction phenotypes.
PARADIGM-HF and PARAGON-HF
The post hoc analysis consisted of 8,399 patients with HF with reduced ejection fraction (HFrEF) in PARADIGM-HF (Eur J Heart Fail. 2013 Sep;15[9]:1062-73) and 4,796 patients with HFpEF in PARAGON-HF (N Engl J Med. 2014 Sep 11;371[11]:993-1004). The analysis focused on the 528 and 510 patients in each study, respectively, who developed pneumonia. Those rates translated to an incidence rate of 29 per 1,000 patient-years (95% confidence interval, 27-31) in PARADIGM-HF and 39 per 1,000 patient-years (95% CI, 36-42) in PARAGON-HF.
After pneumonia, the risk of death in patients increased substantially. In PARADIGM-HF, the adjusted hazard ratio for the risk of death from any cause after pneumonia was 4.34 (95% CI, 3.73-5.05). In PARAGON-HF, it was 3.76 (95% CI, 3.09-4.58). HF patients who contracted pneumonia also tended to have HF longer than their counterparts who didn’t develop pneumonia, but the frequency of previous hospitalization for HF didn’t vary between the pneumonia and no-pneumonia groups.
Patients who developed pneumonia tended to be older (average age of 66.9 years vs. 64.6 years, P < .001) and male (83.9% vs. 77.8%, P < .001). The mean age of patients in PARADIGM-HF was almost a decade younger than those in PARAGON-HF, 64 vs. 73 years.
Pneumonia patients also had worse Kansas City Cardiomyopathy Questionnaire scores (76 vs. 80 on average), but no difference in New York Heart Association functional class. “In general, patients who developed pneumonia had more symptoms and signs and HF than those who did not develop pneumonia,” Dr. McMurray and colleagues wrote.
Pneumonia patients also had higher rates of chronic obstructive pulmonary disease (26% vs. 12%), diabetes (43% vs. 34%), and atrial fibrillation (46% vs. 36%).
Another reason for conducting the study, Dr. McMurray said, “was the prior findings in patients with coronary disease and acute myocardial infarction that the risk associated with an episode of pneumonia [e.g., in subsequent vascular events and deaths] persisted long after the acute event. We wanted to see if this was also the case for heart failure, and indeed it was.”
For example, the adjusted HR for cardiovascular death or hospitalization in the first month following an episode of pneumonia was 9.48 (range of 6.85-13.12, P < .001), leveling off to 1.59 after 3 months or more.
Vaccination crucial in HF patients
Dr. McMurray noted that this study emphasizes the importance of pneumonia vaccination for patients with HF. “Given that we have so few treatments to offer patients with HFpEF, this makes the potential value of vaccination in these patients all the greater,” he said.
The COVID-19 pandemic, Dr. McMurray said, is a “good reminder of the dangers of a respiratory infection and the importance of vaccination in these patients. COVID-19 has interesting parallels in being a systemic disease and one with postacute, persisting effects.”
The persistent risk for adverse cardiovascular events 3 months and later after pneumonia is a novel finding of the study, wrote Donna Mancini, MD, and Gregory Gibson, MD, in an invited commentary (J Am Coll Cardiol. 2021;77:1974-6). Both are with the Icahn School of Medicine at Mt. Sinai in New York. The post hoc study also “serves as an important reminder” of pneumonia risk in patients with HF, especially during the pandemic, they wrote.
“Although vaccination alone appears unlikely to be a panacea, it is a readily accessible tool for mitigating disease severity and improving outcomes,” Dr. Mancini and Dr. Gibson wrote. “After all, an ounce of prevention is worth a pound of cure.”
Novartis provided funding for the PARADIGM-HF and PARAGON-HF trials, and Dr. McMurray and coauthors disclosed financial relationships with Novartis. Dr. Mancini and Dr. Gibson have no relevant financial relationships to disclose.

The correct answer is dermatitis herpetiformis (DH; choice “b”).
DISCUSSION
DH is unusual, although not rare, and it is often overlooked in the investigation of itchy rashes—even by dermatologists. As is so often the case, the biopsy was the missing piece of the puzzle, since it clearly showed changes consistent with this condition.
The history of DH has some interesting overlap with that of biopsy. It was Rudolph Virchow, an 18th century Austrian pathologist, who first connected clinical disease to specific arrangements of disordered tissue seen microscopically—at that time, a giant leap for medicine. An American dermatologist, Louis Adolphus Duhring, had the good fortune to study under Virchow and his successors in Vienna and brought this cutting-edge knowledge back to this country, where he began the process of categorizing diseases by their histologic patterns as well as by their presentation and clinical course. This was when he discovered the basis for the condition that became known as Duhring disease, also known as dermatitis herpetiformis.
It was much later (1967) that a connection was made between DH and the ingestion of gluten. Our patient experienced a rapid decline in his itching and rash as soon as he started a gluten-free diet. However, since many patients find such a diet difficult to maintain, there are pharmacologic options as well: dapsone, colchicine, sulfa drugs, drugs from the tetracycline family, and nicotinamide. All have potential adverse effects with which the prescriber needs to become familiar.
With a combination of medication and reduced gluten intake, it’s entirely possible that the patient’s DH will permanently resolve, although he will remain at increased risk for other autoimmune conditions.

A 56-year-old man began to itch almost 10 years ago, when lesions appeared on his extensor forearms; they later branched out to his knees, scalp, and waistline. He has continued to suffer despite seeing numerous providers, including dermatologists.
An allergist pronounced him free of any significant allergies. Another provider was certain the patient had scabies, although his household was unaffected and the prescribed treatment—permethrin lotion and oral ivermectin—had no impact on the rash or the symptoms. Most of the other consulted providers diagnosed eczema, despite a complete lack of atopy in the patient or his family of origin. Furthermore, treatment with topical, oral, and intramuscular steroids had offered minimal and very short-lived relief. No one took a scraping or performed a biopsy of the rash.
The patient claims to be otherwise healthy, with no gastrointestinal symptoms and no new medications. Examination reveals a slightly overweight man in no distress.
The lesions in question are patches of excoriated papulovesicular lesions. Microscopic examination of a KOH prep shows no scabetic elements. His volar wrists, the sides of his fingers, and his genitals are free of lesions.
A shave biopsy is performed under local anesthetic. The pathology report indicates subepidermal collections of eosinophils.
Antibiotics may prolong PFS in HCC patients on immunotherapy
Response rates and overall survival (OS), on the other hand, did not seem to be affected by antibiotic administration, according to investigator Petros Fessas, MD, of Imperial College London.
Dr. Fessas and colleagues presented these findings in a poster at the American Association for Cancer Research Annual Meeting 2021: Week 1 (Abstract 485).
Dr. Fessas noted that, in other cancers, antibiotics have been shown to reduce both response and survival rates after ICI.
To assess the impact of early antibiotic exposure on ICI efficacy in HCC, Dr. Fessas and colleagues examined data from 449 patients treated at 12 centers in the United States, Europe, and Asia.
The patients’ median age was 65 years, and 79.1% were men. Nearly three-quarters (73.3%) were cirrhotic (60.4% because of viral hepatitis), 79.9% were Child-Pugh class A, 72.4% were Barcelona Clinic Liver Cancer stage C, and 79% had an Eastern Cooperative Oncology Group performance status of 0-1.
Response and survival results
The investigators compared outcomes between patients with and without antibiotic exposure in the early immunotherapy period (EIOP) 30 days before and after ICI initiation.
In all, 170 patients (37.9%) received antibiotics in the EIOP. There were no differences in response rates, disease control rates, or median OS between patients who received antibiotics and those who did not.
The objective response rate was 20.2% in patients who received antibiotics in the EIOP and 16.1% in patients who did not (P = .2808). Disease control rates were 63.1% and 55.4%, respectively (P = .1144). The median OS was 15.3 months and 15.4 months, respectively (hazard ratio, 0.93; 95% confidence interval, 0.72-1.21; P = .6275).
The median PFS, however, was significantly longer in patients who received antibiotics than in patients who did not – 6.1 months and 3.7 months, respectively (HR, 0.74; 95% CI, 0.60-0.93; P = .0135).
To overcome possible bias introduced by misclassification of patients who received antibiotics but discontinued immunotherapy within 30 days of initiation, the investigators conducted a landmark selection analysis among only those patients with a median follow-up for PFS of 30 days or longer (n = 402). This analysis confirmed the prior findings.
“Antibiotic exposure in the 30 days before or after immune checkpoint initiation in hepatocellular carcinoma is associated with prolonged progression-free survival,” Dr. Fessas concluded.
He added that a key question for future research is to discover the immune-microbiologic determinants of response to initiation of ICIs.
Positive effect surprising
“My group has shown that antibiotic therapy is normally detrimental in patients with cancer,” investigator David J. Pinato, MD, PhD, of Imperial College London, said in an interview. “So we were very surprised to see a positive effect on PFS.”
He added that the new findings should be interpreted with caution.
“My feeling is that, unlike with many other malignancies, the gut microbiome is heavily involved in the progression of the cirrhosis that pre-dates HCC onset,” he said.
That would suggest the relationship between antibiotics and perturbation of the gut microbiome is dictated by something more than changes in antitumor immune tolerance, he added.
“Overall, I think the interplay is more complex in HCC: cirrhosis/cancer/microbiome, not just microbiome/cancer as in many other tumors,” Dr. Pinato said. “So we are looking at microbial determinants of response in HCC patients undergoing ICI therapy, and we are hopeful to see some more mechanistic evidence behind this association.”
Dr. Pinato disclosed relationships with ViiV Healthcare, Bayer Healthcare, Bristol Myers Squibb, Mina Therapeutics, Eisai, Roche, and AstraZeneca. Dr. Fessas reported having no conflicts of interest. No funding source for the study was disclosed.

CLL patients: Diagnostic difficulties, treatment confusion with COVID-19
Chronic lymphocytic leukemia (CLL) patients present significant problems with regard to COVID-19 disease, according to a literature review by Yousef Roosta, MD, of Urmia (Iran) University of Medical Sciences, and colleagues.
Diagnostic interaction between CLL and COVID-19 provides a major challenge. CLL patients have a lower rate of anti–SARS-CoV-2 IgG development, and evidence shows worse therapeutic outcomes in these patients, according to study published in Leukemia Research Reports.
The researchers assessed 20 retrieved articles, 11 of which examined patients with CLL and with concomitant COVID-19; and 9 articles were designed as prospective or retrospective case series of such patients. The studies were assessed qualitatively by the QUADAS-2 tool.
Troubling results
Although the overall prevalence of CLL and COVID-19 concurrence was low, at 0.6% (95% confidence interval 0.5%-0.7%) according to the meta-analysis, the results showed some special challenges in the diagnosis and care of these patients.
Diagnostic difficulties are a unique problem. Lymphopenia is common in patients with COVID-19, while lymphocytosis may be considered a transient or even rare finding. The interplay between the two diseases is sometimes very misleading for specialists, and in patients with lymphocytosis, the diagnosis of CLL may be completely ignored, according to the researchers. They added that when performing a diagnostic approach for concurrent COVID-19 and CLL, due to differences in the amount and type of immune response, “relying on serological testing, and especially the evaluation of the anti–SARS-CoV-2 IgG levels may not be beneficial,” they indicated.
In addition, studies showed unacceptable therapeutic outcome in patients with concurrent CLL and COVID-19, with mortality ranging from 33% to 41.7%, showing a need to revise current treatment protocols, according to the authors. In one study, 85.7% of surviving patients showed a considerable decrease in functional class and significant fatigue, with such a poor prognosis occurring more commonly in the elderly.
With regard to treatment, “it is quite obvious that despite the use of current standard protocols, the prognosis of these patients will be much worse than the prognosis of CLL patients with no evidence of COVID-19. Even in the first-line treatment protocol for these patients, there is no agreement in combination therapy with selected CLL drugs along with management protocols of COVID-19 patients,” the researchers stated.
“[The] different hematological behaviors of two diseases might mimic the detection of COVID-19 in the CLL state and vise versa. Also, due to the low level of immune response against SARS-CoV-2 in CLL patients, both scheduled immunological-based diagnosis and treatment may fail,” the researchers added.
The authors reported that they had no disclosures.

Eating more fat may boost borderline low testosterone
Low-fat diets appear to decrease testosterone levels in men, but further randomized, controlled trials are needed to confirm this effect, the authors of a meta-analysis of six small intervention studies concluded.
A total of 206 healthy men with normal testosterone received a high-fat diet followed by a low-fat diet (or vice versa), and their mean total testosterone levels were 10%-15% lower (but still in the normal range) during the low-fat diet.
The study by registered nutritionist Joseph Whittaker, MSc, University of Worcester (England), and statistician Kexin Wu, MSc, University of Warwick, Coventry, England, was published online in the Journal of Steroid Biochemistry and Molecular Biology.
“I think our results are consistent and fairly strong, but they are not strong enough to give blanket recommendations,” Mr. Whittaker said in an interview.
However, “if somebody has low testosterone, particularly borderline, they could try increasing their fat intake, maybe on a Mediterranean diet,” he said, and see if that works to increase their testosterone by 60 ng/dL, the weighted mean difference in total testosterone levels between the low-fat versus high-fat diet interventions in this meta-analysis.
“A Mediterranean diet is a good way to increase ‘healthy fats,’ mono- and polyunsaturated fatty acids, which will likely decrease cardiovascular disease risk, and boost testosterone at the same time,” Mr. Whittaker noted.
Olive oil has been shown to boost testosterone more than butter, and it also reduces CVD, he continued. Nuts are high in “healthy fats” and consistently decrease CVD and mortality and may boost testosterone. Other sources of “good fat” in a healthy diet include avocado, and red meat and poultry in moderation.
“It is controversial, but our results also indicate that foods with saturated fatty acids may boost testosterone,” he added, noting however that such foods are also associated with an increase in cholesterol.
Is waning testosterone explained by leaner diet?
Men need healthy testosterone levels for good physical performance, mental health, and sexual health, and low levels are associated with a higher risk of heart disease, diabetes, and Alzheimer’s disease, according to a statement about this research issued by the University of Worcester.
Although testosterone levels do decline with advancing age, there has also been an additional age-independent and persistent decline in testosterone levels that began roughly after nutrition guidelines began recommending a lower-fat diet in 1965.
Fat consumption dropped from 45% of the diet in 1965 to 35% of the diet in 1991, and stayed around that lower level through to 2011.
However, it is not clear if this decrease in dietary fat intake might explain part of the concurrent decline in men’s testosterone levels.
Mr. Whittaker and Mr. Wu conducted a systematic literature review and identified six crossover intervention studies that compared testosterone levels during low-fat versus high-fat diets – Dorgan 1996, Wang 2005, Hamalainen 1984, Hill 1980, Reed 1987, and Hill 1979 – and then they combined these studies in a meta-analysis.
Five studies each enrolled 6-43 healthy men from North America, the United Kingdom, and Scandinavia, and the sixth study (Hill 1980) enrolled 34 healthy men from North America and 39 farm laborers from South Africa.
Overall, on average, the men were aged 34-54 years and slightly overweight (a mean body mass index of roughly 27 kg/m2) with normal testosterone (i.e., >300 ng/dL, based on the 2018 American Urological Association guidelines criteria).
Most men received a high-fat diet (40% of calories from fat) first, followed by a low-fat diet (on average 20% of calories from fat; range, 7%-25%), but the subgroup of men from South Africa received the low-fat diet first.
To put this into context, U.K. guidelines recommend a fat intake of less than 35% of daily calories, and U.S. guidelines recommend a fat intake of 20%-35% of daily calories.
The low-and high-fat interventions ranged from 2 to 10 weeks.
Lowest testosterone levels with low-fat vegetarian diets
Overall, on average, the men’s total testosterone was 475 mg/dL when they were consuming a low-fat diet and 532 mg/dL when they were consuming a high-fat diet.
However, the South African men had higher testosterone levels when they consumed a low-fat diet. This suggests that “men with European ancestry may experience a greater decrease in testosterone in response to a low-fat diet,” the researchers wrote.
The decrease in total testosterone in the low-fat versus high-fat diet was largest (26%) in the two studies of men who consumed a vegetarian diet (Hill 1979 and Hill 1980). These diets may have been low in zinc, since a marginal zinc deficiency has been shown to decrease total testosterone, Mr. Whittaker and Mr. Wu speculated.
The meta-analysis also showed that levels of free testosterone, urinary testosterone, and dihydrotestosterone declined during the low-fat diet, whereas levels of luteinizing hormone or sex hormone binding globulin were similar with both diets.
Men with low testosterone and overweight, obesity
What nutritional advice should practitioners give to men who have low testosterone and overweight/obesity?
“If you are very overweight, losing weight is going to dramatically improve your testosterone,” Mr. Whittaker said.
However, proponents of various diets are often in stark disagreement about the merits of a low-fat versus low-carbohydrate diet to lose weight.
“In general,” he continued, “the literature shows low-carb (high-fat) diets are better for weight loss [although many will disagree with that statement].”
Although nutrition guidelines have stressed the importance of limiting fat intake, fat in the diet is also associated with lower triglyceride levels and blood pressure and higher HDL cholesterol levels, and now in this study, higher testosterone levels.
More research needed
The researchers acknowledge study limitations: The meta-analysis included just a few small studies with heterogeneous designs and findings, and there was possible bias from confounding variables.
“Ideally, we would like to see a few more studies to confirm our results,” Mr. Whittaker said in the statement. “However, these studies may never come; normally researchers want to find new results, not replicate old ones. In the meantime, men with low testosterone would be wise to avoid low-fat diets.”
This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors. The authors disclosed no relevant financial relationships.

Fat consumption dropped from 45% of the diet in 1965 to 35% of the diet in 1991, and stayed around that lower level through to 2011.
However, it is not clear if this decrease in dietary fat intake might explain part of the concurrent decline in men’s testosterone levels.
Mr. Whittaker and Mr. Wu conducted a systematic literature review and identified six crossover intervention studies that compared testosterone levels during low-fat versus high-fat diets – Dorgan 1996, Wang 2005, Hamalainen 1984, Hill 1980, Reed 1987, and Hill 1979 – and then they combined these studies in a meta-analysis.
Five studies each enrolled 6-43 healthy men from North America, the United Kingdom, and Scandinavia, and the sixth study (Hill 1980) enrolled 34 healthy men from North America and 39 farm laborers from South Africa.
Overall, on average, the men were aged 34-54 years and slightly overweight (a mean body mass index of roughly 27 kg/m2) with normal testosterone (i.e., >300 ng/dL, based on the 2018 American Urological Association guidelines criteria).
Most men received a high-fat diet (40% of calories from fat) first, followed by a low-fat diet (on average 20% of calories from fat; range, 7%-25%), but the subgroup of men from South Africa received the low-fat diet first.
To put this into context, U.K. guidelines recommend a fat intake of less than 35% of daily calories, and U.S. guidelines recommend a fat intake of 20%-35% of daily calories.
The low-and high-fat interventions ranged from 2 to 10 weeks.
Lowest testosterone levels with low-fat vegetarian diets
Overall, on average, the men’s total testosterone was 475 mg/dL when they were consuming a low-fat diet and 532 mg/dL when they were consuming a high-fat diet.
However, the South African men had higher testosterone levels when they consumed a low-fat diet. This suggests that “men with European ancestry may experience a greater decrease in testosterone in response to a low-fat diet,” the researchers wrote.
The decrease in total testosterone in the low-fat versus high-fat diet was largest (26%) in the two studies of men who consumed a vegetarian diet (Hill 1979 and Hill 1980). These diets may have been low in zinc, since a marginal zinc deficiency has been shown to decrease total testosterone, Mr. Whittaker and Mr. Wu speculated.
The meta-analysis also showed that levels of free testosterone, urinary testosterone, and dihydrotestosterone declined during the low-fat diet, whereas levels of luteinizing hormone or sex hormone binding globulin were similar with both diets.
Men with low testosterone and overweight, obesity
What nutritional advice should practitioners give to men who have low testosterone and overweight/obesity?
“If you are very overweight, losing weight is going to dramatically improve your testosterone,” Mr. Whittaker said.
However, proponents of various diets are often in stark disagreement about the merits of a low-fat versus low-carbohydrate diet to lose weight.
“In general,” he continued, “the literature shows low-carb (high-fat) diets are better for weight loss [although many will disagree with that statement].”
Although nutrition guidelines have stressed the importance of limiting fat intake, fat in the diet is also associated with lower triglyceride levels and blood pressure and higher HDL cholesterol levels, and now in this study, higher testosterone levels.
More research needed
The researchers acknowledge study limitations: The meta-analysis included just a few small studies with heterogeneous designs and findings, and there was possible bias from confounding variables.
“Ideally, we would like to see a few more studies to confirm our results,” Mr. Whittaker said in the statement. “However, these studies may never come; normally researchers want to find new results, not replicate old ones. In the meantime, men with low testosterone would be wise to avoid low-fat diets.”
This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors. The authors disclosed no relevant financial relationships.

Low-fat diets appear to decrease testosterone levels in men, but further randomized, controlled trials are needed to confirm this effect, the authors of a meta-analysis of six small intervention studies concluded.
A total of 206 healthy men with normal testosterone received a high-fat diet followed by a low-fat diet (or vice versa), and their mean total testosterone levels were 10%-15% lower (but still in the normal range) during the low-fat diet.
The study by registered nutritionist Joseph Whittaker, MSc, University of Worcester (England), and statistician Kexin Wu, MSc, University of Warwick, Coventry, England, was published online in the Journal of Steroid Biochemistry and Molecular Biology.
“I think our results are consistent and fairly strong, but they are not strong enough to give blanket recommendations,” Mr. Whittaker said in an interview.
However, “if somebody has low testosterone, particularly borderline, they could try increasing their fat intake, maybe on a Mediterranean diet,” he said, and see if that works to increase their testosterone by 60 ng/dL, the weighted mean difference in total testosterone levels between the low-fat versus high-fat diet interventions in this meta-analysis.
“A Mediterranean diet is a good way to increase ‘healthy fats,’ mono- and polyunsaturated fatty acids, which will likely decrease cardiovascular disease risk, and boost testosterone at the same time,” Mr. Whittaker noted.
Olive oil has been shown to boost testosterone more than butter, and it also reduces CVD, he continued. Nuts are high in “healthy fats” and consistently decrease CVD and mortality and may boost testosterone. Other sources of “good fat” in a healthy diet include avocado, and red meat and poultry in moderation.
“It is controversial, but our results also indicate that foods with saturated fatty acids may boost testosterone,” he added, noting however that such foods are also associated with an increase in cholesterol.
Is waning testosterone explained by leaner diet?

How often should we check EKGs in patients starting antipsychotic medications?
Determining relative risk with available data
Case
An 88-year-old woman with history of osteoporosis, hyperlipidemia, and a remote myocardial infarction presents to the ED with altered mental status and agitation. The patient is admitted to the medicine service for further management. Her current medications include a thiazide and a statin. Psychiatry is consulted and recommends administering intravenous haloperidol. A baseline EKG shows a corrected QT interval (QTc) of 486 milliseconds (ms). How often should subsequent EKGs be ordered?
Overview of issue
A prolonged QT interval can predispose a patient to dangerous arrhythmias such as Torsades de pointes (TdP), which results in sudden cardiac death in about 10% of cases.1,2 A prolonged QTc interval can be caused by cardiac, renal, or hepatic dysfunction; congenital Long QT Syndrome (LQTS)2; electrolyte abnormalities; or as a result of many drugs, including most antipsychotic medications such as quetiapine, olanzapine, risperidone and haloperidol.
To diminish risk of TdP while taking these medications, it is necessary to monitor the QTc interval. Before commencing a QT-prolonging medication, it is recommended to get a baseline EKG, then perform EKG monitoring after administering the medication.
According to American Heart Association guidelines, a prolonged QT interval is considered more than 460 ms in women or above 450 ms in men.3 If an abnormal rhythm and/or prolonged QTc is detected via EKG monitoring, then the drug dosage can be changed or an alternative therapy selected.4 However, there are no current guidelines recommending how often EKG monitoring should be performed after a QT-prolonging antipsychotic medication is administered on an inpatient medicine unit. Without guidelines, there is potential for health care providers to under- or over-order EKG monitoring, possibly putting patients at risk of TdP or wasting hospital resources, respectively.
Overview of the data
There are currently no universally accepted guidelines regarding inpatient EKG monitoring for patients started on QTc prolonging antipsychotic medications. A 2018 review of the literature surrounding assessment and management of patients on QTc prolonging medications was performed to analyze the available data and make recommendations; notably the evidence was limited as none of the studies were randomized controlled trials.
The authors recommend assessing the drug for QTc prolonging potential, and if possible, choosing alternative treatment in patients with baseline prolonged QTc. If the QT prolonging medication is the best or only option, then the next step is assessing the patient’s risk for QTc prolongation based on that person’s current condition and medical history.5 They recommend using the QTc prolonging risk point system developed by Tisdale and colleagues, which identified patient risk factors for elevated QTc intervals based on EKG findings in cardiac care units at a large tertiary hospital center.6
Based on the patient’s demographics, current condition, and medication list, the score can be used to stratify patients into low-, medium-, and high-risk categories (see Table 1). 
Risk factors include age over 68 years, female sex, prior MI, concurrent use of other QTc prolonging medications, and sepsis, all of which have differing ability to cause QTc prolongation and thus are weighted differentially. This scoring system is helpful in identifying high risk patients; however, the review does not include recommendations for management of these patients beyond removing the offending drug or monitoring EKGs more aggressively in higher risk patients once identified.6
Low-risk patients can be managed expectantly. If the baseline QTc is < 500 ms, then the provider may administer the medication, but should obtain follow-up EKG monitoring to ensure the QTc does not rise above 500 ms; if it does, a management change is necessitated. For moderate- to high-risk patients with a baseline QTc > 500 ms, they recommend not administering the medication and consulting a cardiologist. The review does not provide a recommendation on how often EKG monitoring should be performed after prescribing an antipsychotic medication in an inpatient setting.5
A 2018 review article explored patient risk factors for a prolonged QTc in the setting of prescribing potentially QTc prolonging antipsychotics.7 The authors reiterate that QTc prolonging risk factors are important considerations when prescribing antipsychotics that can lead to adverse events, though they note that much of the literature associating antipsychotics with negative outcomes consists of case reports in which patients had independent risk factors for development of TdP, such as preexisting ventricular arrhythmias.
In addition, the data regarding the risk of each individual antipsychotic agent are not comprehensive. Some medications that have been deemed “QTc prolonging” were identified as such in only a handful of cases where patients had confounding comorbid risk factors. This raises concern that some medications are being unduly stigmatized in situations where there is little chance of TdP. If there is no equivalent or alternate treatment available, this may lead to an antipsychotic medication being held unnecessarily, which may exacerbate the psychiatric illness.
The authors note that the trend toward ordering baseline EKGs in the inpatient setting following administration of a new antipsychotic may be partly attributed to the ready availability of EKG testing in hospitals. They recommend a baseline EKG to assess the patient’s risk. For most agents, they recommend no further EKG monitoring unless there is a change in patient risk factors. Follow-up EKGs should be done in patients with multiple or significant risk factors to assess their QTc stability. In patients with a QTc > 500 ms on a follow-up EKG, daily monitoring is encouraged alongside reassessment of the current treatment regimen.7
Overall, the current literature suggests that providers should know which antipsychotics carry a risk for QTc prolongation and what other treatment options are available. The risk of QTc prolongation for common antipsychotic agents is provided in Table 2.
Providers should assess their patients’ risk factors for QTc prolongation and order a baseline EKG to help quantify the cardiac risk associated with prescribing the drug. In patients with many risk factors or complicated medication regimens, a follow-up EKG should be performed to assess the new QTc baseline. If the subsequent QTc is > 500 ms, then an alternative medication should be strongly considered. The majority of patients, however, will not have a clinically significant increase in their QTc, in which case there is no need for a change in medication and monitoring frequency can be deescalated.
Application of data to the case
Our 88-year-old patient has multiple risk factors for a prolonged QTc, and according to the Tisdale scoring system is at moderate risk (7-10 points). Her risk of developing TdP increases with the addition of IV haloperidol to her regimen.
Because of her increased risk, it is reasonable to consider alternative management. If she can cooperate with PO medications, then olanzapine could be given, which has a lesser effect on the QTc interval. If unable to take oral medications, she could be given haloperidol intramuscularly, which causes less QTc prolongation than the IV formulation. If an antipsychotic is administered, she should receive EKG monitoring.
Given the lack of evidence on the optimal monitoring strategy, a protocol should be utilized that balances the ability to capture a clinically meaningful increase in the QTc with appropriate stewardship of resources. Our practice is to initially monitor the EKG every 3 days in moderate- to high-risk patients with baseline QTc < 500 ms. If the QTc remains below 500 ms over three EKGs, then treatment may continue with EKG monitoring weekly while the patient is hospitalized. If the QTc rises above 500 ms, then a management change would be indicated (either dose reduction or a change of agents). If antipsychotic medications are continued, we check the EKG daily while the QTc is >500 ms until there are three unchanged EKGS, and then consider deescalating monitoring to every 3 days.
Bottom line
Prior to prescribing, perform a baseline EKG and assess the patient’s risk of QTc prolongation. If the patient is at increased risk, avoid prescribing QTc prolonging medications where alternatives exist. If a QTc prolonging medication is used in a patient with a moderate- to high-risk score, check an EKG every 3 days or daily if the QTc increases to > 500 ms.

Key points
- An increased QTc interval can lead to TdP, ventricular fibrillation and cardiac death.
- The relative risk of each antipsychotic medication should be determined based on available data and the Tisdale scoring system can provide a system to assess a patient’s risk of QTc prolongation.
- Low-risk patients with a baseline QTc <500 ms should receive a baseline EKG and inpatient EKG monitoring weekly while moderate- to high-risk patients should receive EKG monitoring every 3 days.
- A QTc > 500 ms suggests the need for a management change (drug discontinuation, dose reduction, or a switch to another agent). If the antipsychotic is absolutely necessary, perform daily EKG monitoring until there are three unchanged EKGs, and then consider deescalating monitoring to every 3 days.

Key points
- An increased QTc interval can lead to TdP, ventricular fibrillation and cardiac death.
- The relative risk of each antipsychotic medication should be determined based on available data and the Tisdale scoring system can provide a system to assess a patient’s risk of QTc prolongation.
- Low-risk patients with a baseline QTc <500 ms should receive a baseline EKG and inpatient EKG monitoring weekly while moderate- to high-risk patients should receive EKG monitoring every 3 days.
- A QTc > 500 ms suggests the need for a management change (drug discontinuation, dose reduction, or a switch to another agent). If the antipsychotic is absolutely necessary, perform daily EKG monitoring until there are three unchanged EKGs, and then consider deescalating monitoring to every 3 days.

Quiz
A 70-year-old male inpatient on furosemide with last known potassium level of 3.3 is going to be started on olanzapine. His baseline EKG has a QTc of 470 ms.
How often should he receive EKG monitoring?
A. Daily
B. Every 3 days
C. Weekly
D. Monthly
Answer (C): He is a low risk patient (6 points: over 70 yrs, loop diuretic, K+< 3.5, QTc > 450 ms), so he should receive weekly EKG monitoring.
Case
An 88-year-old woman with history of osteoporosis, hyperlipidemia, and a remote myocardial infarction presents to the ED with altered mental status and agitation. The patient is admitted to the medicine service for further management. Her current medications include a thiazide and a statin. Psychiatry is consulted and recommends administering intravenous haloperidol. A baseline EKG shows a corrected QT interval (QTc) of 486 milliseconds (ms). How often should subsequent EKGs be ordered?
Overview of issue
A prolonged QT interval can predispose a patient to dangerous arrhythmias such as Torsades de pointes (TdP), which results in sudden cardiac death in about 10% of cases.1,2 A prolonged QTc interval can be caused by cardiac, renal, or hepatic dysfunction; congenital Long QT Syndrome (LQTS)2; electrolyte abnormalities; or as a result of many drugs, including most antipsychotic medications such as quetiapine, olanzapine, risperidone and haloperidol.
To diminish risk of TdP while taking these medications, it is necessary to monitor the QTc interval. Before commencing a QT-prolonging medication, it is recommended to get a baseline EKG, then perform EKG monitoring after administering the medication.
According to American Heart Association guidelines, a prolonged QT interval is considered more than 460 ms in women or above 450 ms in men.3 If an abnormal rhythm and/or prolonged QTc is detected via EKG monitoring, then the drug dosage can be changed or an alternative therapy selected.4 However, there are no current guidelines recommending how often EKG monitoring should be performed after a QT-prolonging antipsychotic medication is administered on an inpatient medicine unit. Without guidelines, there is potential for health care providers to under- or over-order EKG monitoring, possibly putting patients at risk of TdP or wasting hospital resources, respectively.
Overview of the data
There are currently no universally accepted guidelines regarding inpatient EKG monitoring for patients started on QTc prolonging antipsychotic medications. A 2018 review of the literature surrounding assessment and management of patients on QTc prolonging medications was performed to analyze the available data and make recommendations; notably the evidence was limited as none of the studies were randomized controlled trials.
The authors recommend assessing the drug for QTc prolonging potential, and if possible, choosing alternative treatment in patients with baseline prolonged QTc. If the QT prolonging medication is the best or only option, then the next step is assessing the patient’s risk for QTc prolongation based on that person’s current condition and medical history.5 They recommend using the QTc prolonging risk point system developed by Tisdale and colleagues, which identified patient risk factors for elevated QTc intervals based on EKG findings in cardiac care units at a large tertiary hospital center.6
Based on the patient’s demographics, current condition, and medication list, the score can be used to stratify patients into low-, medium-, and high-risk categories (see Table 1).
Risk factors include age over 68 years, female sex, prior MI, concurrent use of other QTc prolonging medications, and sepsis, all of which have differing ability to cause QTc prolongation and thus are weighted differentially. This scoring system is helpful in identifying high risk patients; however, the review does not include recommendations for management of these patients beyond removing the offending drug or monitoring EKGs more aggressively in higher risk patients once identified.6
Low-risk patients can be managed expectantly. If the baseline QTc is < 500 ms, then the provider may administer the medication, but should obtain follow-up EKG monitoring to ensure the QTc does not rise above 500 ms; if it does, a management change is necessitated. For moderate- to high-risk patients with a baseline QTc > 500 ms, they recommend not administering the medication and consulting a cardiologist. The review does not provide a recommendation on how often EKG monitoring should be performed after prescribing an antipsychotic medication in an inpatient setting.5
A 2018 review article explored patient risk factors for a prolonged QTc in the setting of prescribing potentially QTc prolonging antipsychotics.7 The authors reiterate that QTc prolonging risk factors are important considerations when prescribing antipsychotics that can lead to adverse events, though they note that much of the literature associating antipsychotics with negative outcomes consists of case reports in which patients had independent risk factors for development of TdP, such as preexisting ventricular arrhythmias.
In addition, the data regarding the risk of each individual antipsychotic agent are not comprehensive. Some medications that have been deemed “QTc prolonging” were identified as such in only a handful of cases where patients had confounding comorbid risk factors. This raises concern that some medications are being unduly stigmatized in situations where there is little chance of TdP. If there is no equivalent or alternate treatment available, this may lead to an antipsychotic medication being held unnecessarily, which may exacerbate the psychiatric illness.
The authors note that the trend toward ordering baseline EKGs in the inpatient setting following administration of a new antipsychotic may be partly attributed to the ready availability of EKG testing in hospitals. They recommend a baseline EKG to assess the patient’s risk. For most agents, they recommend no further EKG monitoring unless there is a change in patient risk factors. Follow-up EKGs should be done in patients with multiple or significant risk factors to assess their QTc stability. In patients with a QTc > 500 ms on a follow-up EKG, daily monitoring is encouraged alongside reassessment of the current treatment regimen.7
Overall, the current literature suggests that providers should know which antipsychotics carry a risk for QTc prolongation and what other treatment options are available. The risk of QTc prolongation for common antipsychotic agents is provided in Table 2.
Providers should assess their patients’ risk factors for QTc prolongation and order a baseline EKG to help quantify the cardiac risk associated with prescribing the drug. In patients with many risk factors or complicated medication regimens, a follow-up EKG should be performed to assess the new QTc baseline. If the subsequent QTc is > 500 ms, then an alternative medication should be strongly considered. The majority of patients, however, will not have a clinically significant increase in their QTc, in which case there is no need for a change in medication and monitoring frequency can be deescalated.
Application of data to the case
Our 88-year-old patient has multiple risk factors for a prolonged QTc, and according to the Tisdale scoring system is at moderate risk (7-10 points). Her risk of developing TdP increases with the addition of IV haloperidol to her regimen.
Because of her increased risk, it is reasonable to consider alternative management. If she can cooperate with PO medications, then olanzapine could be given, which has a lesser effect on the QTc interval. If unable to take oral medications, she could be given haloperidol intramuscularly, which causes less QTc prolongation than the IV formulation. If an antipsychotic is administered, she should receive EKG monitoring.
Given the lack of evidence on the optimal monitoring strategy, a protocol should be utilized that balances the ability to capture a clinically meaningful increase in the QTc with appropriate stewardship of resources. Our practice is to initially monitor the EKG every 3 days in moderate- to high-risk patients with baseline QTc < 500 ms. If the QTc remains below 500 ms over three EKGs, then treatment may continue with EKG monitoring weekly while the patient is hospitalized. If the QTc rises above 500 ms, then a management change would be indicated (either dose reduction or a change of agents). If antipsychotic medications are continued, we check the EKG daily while the QTc is >500 ms until there are three unchanged EKGS, and then consider deescalating monitoring to every 3 days.
Bottom line
Prior to prescribing, perform a baseline EKG and assess the patient’s risk of QTc prolongation. If the patient is at increased risk, avoid prescribing QTc prolonging medications where alternatives exist. If a QTc prolonging medication is used in a patient with a moderate- to high-risk score, check an EKG every 3 days or daily if the QTc increases to > 500 ms.

Risk of hypogammaglobulinemia, infections with rituximab increased in pediatric patients
A quarter of children receiving treatment with rituximab developed hypogammaglobulinemia within 18 months of starting the drug, according to preliminary research shared at the annual scientific meeting of the Childhood Arthritis and Rheumatology Research Alliance. The findings lend support to previous research identifying a risk of hypogammaglobulinemia in children and adolescents taking rituximab and the need for monitoring immunoglobulin levels in those prescribed it.
“Our study highlights a role for heightened vigilance of rituximab-associated hypogammaglobulinemia and infections in pediatric patients with rheumatic conditions,” Mei-Sing Ong, PhD, of Harvard Medical School and the Harvard Pilgrim Health Care Institute, both in Boston, and colleagues concluded. “Increased risks appeared to be mediated, at least in part, by exposure to glucocorticoids (hypogammaglobulinemia and serious infections) or cyclophosphamide (hypogammaglobulinemia) administered prior to rituximab.”
The observational study involved a cohort of 93 patients, aged 2-25 years, treated at Boston Children’s Hospital during 2009-2019. The patients received rituximab for a wide range of rheumatic diseases, including systemic lupus erythematosus, vasculitis, juvenile idiopathic arthritis, and juvenile dermatomyositis or other polymyositis. The researchers excluded patients who had previously had hypogammaglobulinemia before using rituximab.
In this cohort, 26.9% of patients developed hypogammaglobulinemia, and 20.4% of patients developed an infectious complication within 18 months of beginning rituximab treatment. The infection was serious enough to require inpatient treatment in more than half of those who developed infections (57.9%).
Risk of new-onset hypogammaglobulinemia increased with decreasing age (P = .004), and males were more than four times more likely to develop the condition (odds ratio, 4.55; P = .012). Risk of an infection was also more likely among younger patients (OR, 0.87; P = .039).
Patients with vasculitis were fivefold more likely to develop the hypogammaglobulinemia than were those with other rheumatic diseases after the researchers accounted for age, sex, underlying disease, and medication use (OR, 5.04; P = .017). Risk was also greater in patients with exposure to cyclophosphamide in the year before starting rituximab (OR, 3.76; P = .032), although the finding narrowly reached statistical significance after adjustment for those covariates (OR, 4.41; P = .048).
Glucocorticoid treatment in the month before rituximab was associated with an elevated risk of hypogammaglobulinemia before adjustment (OR, 4.53; P = .007) but lost significance after adjustment. Those taking glucocorticoids had a greater than eightfold increase in infection risk (OR, 8.5; P = .006) before adjustment, which dropped to a fivefold risk after accounting for age, sex, underlying disease, and medication use (OR, 5.4; P = .040).
Monitoring needed for relatively common side effect
The findings are consistent with those seen in a cohort study conducted at Lurie Children’s Hospital of Chicago and published in 2019, said Amer M. Khojah, MD, an attending physician in allergy, immunology, and rheumatology at Lurie and an assistant professor of pediatrics at Northwestern University, also in Chicago. He was not involved in the current study.
“The main takeaway from this study is that we need to be careful about this side effect because it’s relatively common,” Dr. Khojah said in an interview.
At his institution, all patients undergo baseline labs to measure IgG levels prior to initiating rituximab and then have labs drawn again at 3 months and 1 year after starting the drug. Transient hypogammaglobulinemia may not require treatment, he said, but if it persists or the patient develops an infection, treatment with intravenous immunoglobulin is indicated. Yet the drug is so commonly used across a wide range of specialties that there’s a great deal of variability in clinical practice in terms of monitoring and follow-up, Dr. Khojah said.
“The problem is, if you don’t measure it, the patient might be get hypogammaglobulinemia and you don’t know it,” potentially leading to infections that the physician may or may not hear about, he said. “If you are the one who gives them the rituximab, you need to make sure they don’t get the side effects” or that they receive treatment if they do, he said.
Casey L. McAtee, MD, an instructor in the section of hematology and oncology in the department of pediatrics at Baylor College of Medicine, Houston, agreed that developing a consistent monitoring schedule is important.
“These data are supportive of the necessity to follow patients closely for infection after rituximab, especially considering that many infections may be severe and require hospitalization,” Dr. McAtee said in an interview. “The period of immunosuppression and subsequent infection risk following rituximab, even after single courses, may last well beyond a year following a single course. This is particularly true in patients receiving concurrent immunosuppressive therapy.”
Dr. McAtee similarly published data this year finding frequent infections among young patients receiving rituximab. Hypogammaglobulinemia is already more likely in patients who require rituximab because of other immunosuppressive medication they often take, but the risk “jumped substantially following rituximab,” he said. In addition to patients with low levels of IgG, 41% of patients showed low levels of IgM in that study.
“Nearly a third of patients with normal baseline IgM had persistently low levels more than a year after rituximab, consistent with prolonged B-cell recovery,” Dr. McAtee said. “It is necessary to highlight the importance of IgM in these patients, as common strategies to treat hypogammaglobulinemia, specifically intravenous immunoglobulin, do not replete IgM.”
Neither Dr. Khojah nor Dr. McAtee saw the risk of hypogammaglobulinemia as a reason to avoid rituximab when indicated.
“It is often the best choice for patients whose diseases have not responded to first-line therapies,” Dr. McAtee said. “This and similar studies inform the risk-benefit decision that the medical team must make, as well as the medical surveillance to be considered for patients following a course of rituximab. Going forward, strategies to mitigate infection risk after rituximab, particularly in the first 3 months when they are most common, should be pursued.”
The research was funded by CARRA, which receives funding from the Arthritis Foundation. The authors did not note whether they had any disclosures. Dr. Khojah and Dr. McAtee had no disclosures.

Casey L. McAtee, MD, an instructor in the section of hematology and oncology in the department of pediatrics at Baylor College of Medicine, Houston, agreed that developing a consistent monitoring schedule is important.
“These data are supportive of the necessity to follow patients closely for infection after rituximab, especially considering that many infections may be severe and require hospitalization,” Dr. McAtee said in an interview. “The period of immunosuppression and subsequent infection risk following rituximab, even after single courses, may last well beyond a year following a single course. This is particularly true in patients receiving concurrent immunosuppressive therapy.”
Dr. McAtee similarly published data this year finding frequent infections among young patients receiving rituximab. Hypogammaglobulinemia is already more likely in patients who require rituximab because of other immunosuppressive medication they often take, but the risk “jumped substantially following rituximab,” he said. In addition to patients with low levels of IgG, 41% of patients showed low levels of IgM in that study.
“Nearly a third of patients with normal baseline IgM had persistently low levels more than a year after rituximab, consistent with prolonged B-cell recovery,” Dr. McAtee said. “It is necessary to highlight the importance of IgM in these patients, as common strategies to treat hypogammaglobulinemia, specifically intravenous immunoglobulin, do not replete IgM.”
Neither Dr. Khojah nor Dr. McAtee saw the risk of hypogammaglobulinemia as a reason to avoid rituximab when indicated.
“It is often the best choice for patients whose diseases have not responded to first-line therapies,” Dr. McAtee said. “This and similar studies inform the risk-benefit decision that the medical team must make, as well as the medical surveillance to be considered for patients following a course of rituximab. Going forward, strategies to mitigate infection risk after rituximab, particularly in the first 3 months when they are most common, should be pursued.”

Postpartum health care needs exceed those of nonpostpartum patients
Postpartum women with commercial health insurance use substantially more inpatient and outpatient care than nonpostpartum women, particularly in the first 2 months after giving birth, according to a retrospective cohort study published in the May 2021 issue of Obstetrics & Gynecology.
“These findings are consistent with previous studies that have documented elevated postpartum ED and hospitalization rates, and we contribute new evidence that indicates postpartum health care utilization rates are significantly higher than rates of health care utilization in the general population of reproductive aged women when they are not pregnant or postpartum,” Maria W. Steenland, ScD, of Brown University, Providence, R.I., and colleagues wrote. “Most notably, postpartum women were more than three times more likely to have an ED visit and eight times more likely to be hospitalized than nonpostpartum women in the early postpartum period.”
Approximately one-third of maternal deaths occur between 1 week and 1 year post partum, the authors noted in their background information. The overall U.S. maternal mortality rate was 17.4 per 100,000 live births in 2018, according to the Centers for Disease Control and Prevention.
“This study underscores the importance of access to health care for women, in particular in the postpartum period,” Iris Krishna, MD, MPH, an assistant professor of maternal-fetal medicine at Emory University, Atlanta, said in an interview. “Maternal mortality is a public health crisis. The majority of maternal deaths are preventable and occur up to 1 year postpartum. Studies such as these are needed as the postpartum period is a critical time in the care of reproductive age women that is often overlooked.”
Using data from a large national commercial claims database, the researchers analyzed data from 149,563 women aged 18-44 years who gave birth in 2016 and from 2,048,831 women who were neither pregnant nor post partum during the same study period. In postpartum women, the researchers specifically looked at hospitalization, preventive visits, problem visits, and ED visits during three periods for postpartum women: early postpartum, defined as within 21 days of giving birth; postpartum, defined as 21-60 days after birth; and extended postpartum, defined as 61 days to 1 year after birth. These data were then compared with equivalent periods in nonpostpartum women.
“For the comparison group, we created a random start date of follow-up by generating a random variable between 0 and 365 and adding this integer to Jan. 1, 2016,” the authors explained. “These start dates correspond to the range of possible follow-up start dates among postpartum women who gave birth in 2016.”
The groups differed in age composition: 62% of the postpartum women were between 25 and 34 years old while the nonpostpartum women were more evenly distributed across the age range. A higher proportion of nonpostpartum women had a chronic disease, but median income and geographic region were similar between the groups. Just over a third of the postpartum women (36%) had a cesarean delivery, higher than the 2016 national average of 32%.
Nearly a quarter (23.7%) of postpartum women had a problem visit in the early postpartum period, compared with one in five (19.7%) nonpostpartum women in the equivalent period. This 4-point difference increased to an 4.8-point difference after adjustment for age group, chronic disease, geographic region, income, and month when follow-up began.
Postpartum women were also three times more likely to have an ED visit (3.2%) in the early postpartum period than nonpostpartum women (1%). Postpartum women’s problem visits and ED visits were most prevalent in the first 2 weeks after childbirth: 12.4% in the first week and 10.4% in the second. Complaints for these visits primarily included urinary tract infections and other genitourinary issues, hypertension, breast or breastfeeding issues, and respiratory issues, such as shortness of breath or chest pain. Hospitalization rates were also higher in the early postpartum period for postpartum women (0.8%) than nonpostpartum women (0.1%).
Problem visits showed a similar pattern during the postpartum period from 21 to 60 days after birth: 39.4% of postpartum women, compared with 30.2% of nonpostpartum women. Rate differences were narrower for ED visits (2% post partum vs. 1.9% non–post partum) and hospitalization (0.3% post partum vs. 0.2% non–post partum), but the differences remained significant, and ED visits were still 0.3 points higher after adjustment.
The biggest differences between the groups in the first 2 months occurred with preventive care. In the early postpartum period, 15% of postpartum women had a preventive visit, compared with 3.3% of nonpostpartum women. Similarly, the rates were 28.2% in postpartum women and 6.5% in nonpostpartum women in the postpartum period.
Differences between the groups evened out in the extended postpartum period, when postpartum women had slightly fewer preventive visits (42.5%) than nonpostpartum women (42.7%). ED rates (11.2% postpartum vs 11.1%) and hospitalization rates (1.4% postpartum vs. 1.6%) were similar, but postpartum women were significantly more likely to have problem visits (79.2%) in the year after childbirth than nonpostpartum women (72.8%).
“Compared with postpartum women overall, postpartum women with chronic disease, pregnancy complications, and cesarean births were more likely to receive health care of all types in the early postpartum period,” the researchers reported. “Of the three subgroups, health care use was highest among postpartum women with chronic disease, among whom 35% had at least one outpatient problem visit, 5% had an ED visit, and 1.3% were hospitalized within the first 20 days of childbirth.”
These findings as a whole point to an increased need for health care not only in the first 3 weeks after women give birth but “beyond the traditional 6-week postpartum period, which adds to the argument that the way we care for women in the postpartum period should be revised,” Dr. Krishna said.
The American College of Obstetricians and Gynecologists updated their postpartum recommendations in 2018 to advise that all postpartum women have a follow-up visit in the first 3 weeks after birth.
Dr. Krishna reiterated that postpartum patients should ideally have an initial follow-up within 3 weeks of giving birth, which the rapid expansion of telehealth has made more viable for both clinicians and mothers.
The authors similarly noted that telehealth and home visits “are promising options to promote early and consistent health care contact and reduce known barriers to postpartum care seeking such as fatigue, lack of transportation, and child care.” Predischarge guidance may also help meet postpartum patients’ health care needs.
“Health care professionals also may be able to reduce the escalation of common early postpartum problems identified in this study (e.g., respiratory problems, pain, urinary tract infections) with anticipatory postpartum counseling and care before hospital discharge such as ensuring that women have inhalers at home, developing a pain management plan, and screening for signs of urinary tract infection,” the authors wrote.
Dr. Krishna also pointed out the need to address racial inequalities in health care and material mortality.
“Black women have a maternal mortality rate two times the rate of non-Hispanic White women,” Dr. Krishna said. “One way to address health disparities between commercially insured and uninsured women is improving access to health care through Medicaid expansion for at least 1 year post partum. States that participated in the Affordable Care Acts Medicaid expansion have noted improvement in maternal mortality and a decrease in racial/ethnic inequities.”
