Patients with neuropsychiatric manifestations of systemic lupus erythematosus (NPSLE) seem to benefit from rituximab (Rituxan) therapy, according to data from the British Isles Lupus Assessment Group Biologics Register (BILAG-BR).

Indeed, the percentage of patients with active disease, as scored by the BILAG-2004 index or SLEDAI-2K (SLE Disease Activity Index 2000), fell significantly (P < .0001) when comparing pre- and postrituximab treatment scores. There was also a reduction in the dose of oral steroids used.

Interestingly, the use of concomitant cyclophosphamide might enhance the level of improvement seen in some patients, Trixy David, MBBS, reported during an abstract session at the British Society for Rheumatology annual conference.

“Larger-scale studies are warranted to establish the effectiveness of rituximab alone, or in combination with cyclophosphamide, in the treatment neuropsychiatric lupus,” said Dr. David, a clinical research fellow at the University of Manchester (England) and specialist registrar in rheumatology at the Manchester University National Health Service Foundation Trust.

Neil Basu, MBChB, PhD, who chaired the virtual session, called the findings “enlightening” and “descriptive.”

The study “provides some interesting data, which should be tested in a robust, randomized clinical trial,” he agreed, and not that clinicians should now start using rituximab for their NPSLE cases.

Dr. Basu, who is a clinical senior lecturer in rheumatology and honorary consultant rheumatologist at the Institute of Infection, Immunity and Inflammation at the University of Glasgow, added: “It is really important that we do these studies to help support a rationale for such a trial, which are obviously very expensive and require strong evidence before we go down that track. I think these data have really been quite enlightening in that respect.”

Rationale for rituximab in neuropsychiatric lupus

Managing patients with NPSLE remains an area of substantial unmet need. According to a recent review in Rheumatology, “there is a dearth of controlled clinical trials to guide management” and “therapeutic options include symptomatic, antithrombotic, and immunosuppressive agents that are supported by observational cohort studies.”

Despite being seen in at least half of all patients with SLE, neuropsychiatric disease “is not very well studied in patients with lupus, as a lot of large-scale trials tend to exclude patients with active neurological disease,” Dr. David said.

Although it is unclear why neuropsychiatric disease occurs in SLE, it could be “as a result of vascular injury or disruption of the blood brain barrier, thereby allowing the passive diffusion of autoantibodies and cytokines across through the cerebral spinal fluid, thereby generating a proinflammatory response,” Dr. David suggested.

“We know B cells are involved in the pathogenesis of lupus, and rituximab is a chimeric monoclonal antibody that selectively targets CD20-positive B cells and mediates transient B-cell depletion,” she said. Notably, there have been some small studies suggesting that rituximab may be effective in neuropsychiatric lupus, and it is currently widely used to treat refractory lupus in the United Kingdom.
 

About the BILAG-BR and results

“Our aim was to describe the baseline characteristics and short-term effectiveness of rituximab in patients treated for neuropsychiatric lupus within the BILAG-BR,” Dr. David explained.

Started in 2009, the BILAG-BR now contains information on more than 1,400 individuals with SLE who have been recruited at 62 centers in the United Kingdom. Its purpose is to evaluate the long-term safety and effectiveness of biologic drugs versus standard immunosuppressive therapy such as azathioprine, mycophenolate mofetil, cyclophosphamide, and cyclosporine. To date, 1,229 patients have been treated with biologics, of whom 1,056 have received rituximab.

A total of 74 rituximab-treated patients were identified as having active neuropsychiatric disease, making this “the largest prospective observational cohort to date, to our knowledge,” Dr. David said.

The median age of patients was 45.5 years, the majority was female (82%) and White (74%). The median disease duration was 11.5 years.

A total of 96% had multiple organ involvement and not just neuropsychiatric disease, and 91% were positive for antineutrophil antibodies.

The top six neuropsychiatric manifestations were cognitive dysfunction and lupus headache (both affecting 27.5% of patients); acute confessional state or mononeuropathy (each seen in 10% of patients); and seizure disorder and polyneuropathy, seen in a respective 8.6% and 8.7% of patients. These findings are in line with a 2011 meta-analysis, Dr. David pointed out.

BILAG-2004 scores before and after rituximab treatment were available for 50 patients. The number of patients with a BILAG A score dropped from 24 (48%) at baseline to 7 (14%) after treatment with rituximab, and the number with a BILAG B score declined from 26 (52%) at baseline to 4 (8%) after rituximab (both P < .0001).

There was also a reduction following rituximab treatment in the percentage of patients categorized as having mainly central nervous system disease (70% vs. 11%), peripheral nervous system disease (19% vs. 6%), or both (11% vs. 8%).

Total SLEDAI-2K scores were also reduced following rituximab treatment, from a median of 12 at baseline to 2 (P < .0001).

Pre- and postrituximab oral prednisolone doses were a median of 15 mg and 10 mg (P = .009).

Limitations

“Our data are from a real-world setting of patients who had active neuropsychiatric disease and were treated with rituximab,” Dr. David said. There are of course many limitations that go hand in hand with observational studies.

“There was the issue of missing data,” Dr. David said. It was difficult or not possible to determine what doses of steroids patients were taking after rituximab therapy, particularly in terms of intravenous steroids, and what doses of any other concomitant disease-modifying therapy might have been around the time that patients initiated or stopped rituximab treatment.

“These could have acted as potential confounders,” she acknowledged.

Dr. Basu noted: “My major haziness from it is the uncertainty of knowing why these patients improved. Yes, they had rituximab, but I’m sure also that they probably received high doses of steroids if they had quite severe CNS lupus which was categorized as a BILAG-A or a B.”

Patients may also be given methylprednisolone when clinicians are really concerned, he continued, and “as was quite clearly pointed out,” there was quite a lot of missing data from a steroid perspective.

Dr. David and coinvestigators reported having no conflicts of interest. The BILAG-BR is supported by funding from Lupus UK, GlaxoSmithKline, and Roche. Dr. Basu did not state having any disclosures.

Barrett’s esophagus occurred in nearly 12% of patients who underwent esophagogastroduodenoscopy after sleeve gastrectomy, but it was not associated with postoperative gastroesophageal reflux disease (GERD), based on data from 10 studies that totaled 680 adult patients.

ChrisPole/thinkstock

Sleeve gastrectomy has become more popular in recent years as an effective strategy for patients with severe obesity, wrote Bashar J. Qumseya, MD, of the University of Florida, Gainesville, and colleagues. However, GERD is a common concern for patients undergoing sleeve gastrectomy and is the major risk factor for Barrett’s esophagus. However, the prevalence of Barrett’s esophagus in the sleeve gastrectomy population has not been examined.

In a meta-analysis published in Gastrointestinal Endoscopy, the researchers reviewed 10 studies that totaled 680 patients who underwent esophagogastroduodenoscopy 6 months to 10 years after a sleeve gastrectomy procedure. The primary outcome was Barrett’s esophagus prevalence in sleeve gastrectomy patients, with the prevalence of erosive esophagitis and GERD at follow-up as secondary outcomes.

Overall, 54 patients developed Barrett’s esophagus, for a pooled prevalence of 11.6%, and all cases were nondysplastic and de novo. There was no significant association between Barrett’s esophagus and the presence of postoperative GERD, the researchers said (odds ratio, 1.74; P = .37).

However, the rate of erosive esophagitis increased by 86% in five studies with long-term follow-up and by 35% in two studies with short-term follow-up, which suggests an increased risk of 13% each year after sleeve gastrectomy, the researchers noted.

Besides the risk of Barrett’s esophagus after sleeve gastrectomy, “the risk of [erosive esophagitis] is also of significant interest and shares the same pathophysiology with [Barrett’s esophagus] and GERD,” they emphasized.

The study findings were limited by several factors including the small sample size and the focus on Barrett’s esophagus rather than erosive esophagitis or GERD as the primary outcome, the researchers noted. However, the results indicate that sleeve gastrectomy patients are at increased risk for Barrett’s esophagus, and larger studies are needed to better understand the pathophysiology. Furthermore, although there is some debate regarding the risk of GERD and erosive esophagitis after sleeve gastrectomy, the authors wrote that the data from their study showed a “consistent and substantial trend” toward more erosive esophagitis after sleeve gastrectomy.

“Gastroenterologists, primary care providers, and bariatric surgeons should be aware” of the data and should discuss the risks of sleeve gastrectomy with patients before the procedure, including the risks and benefits of postprocedure screening for Barrett’s esophagus, they concluded.
 

Consider surveillance for Barrett’s

The study is important because of the increased rates of GERD and potentially Barrett’s esophagus that have been noted after sleeve gastrectomy, Gyanprakash A. Ketwaroo, MD, of Baylor College of Medicine, Houston, said in an interview.

“Many of these studies have been small, and the findings of meta-analyses have been limited by high heterogeneity,” he noted. “With the rise in popularity of sleeve gastrectomy, it is important to accurately assess potential long-term complications.”

Dr. Ketwaroo said he was not surprised by the study findings given several reports of increased GERD after sleeve gastrectomy. “Given the accepted pathophysiology of Barrett’s esophagus, I anticipated increased risk of Barrett’s esophagus after sleeve gastrectomy as well.

“Clinicians should consider surveillance for Barrett’s esophagus after sleeve gastrectomy, and possible early proton pump inhibitor use for both GERD/erosive esophagitis and Barrett’s esophagus chemoprophylaxis. Patients with longer-segment or dysplastic Barrett’s esophagus prior to sleeve gastrectomy may have to be monitored more closely after surgery,” he said.

Dr. Ketwaroo noted that the study was limited by the small sample size, “with only approximately 50 patients with Barrett’s esophagus after surgery among 680 overall.” He emphasized that “we will need a much larger prospective study to confirm this finding. Additionally, I would want to explore if sleeve gastrectomy increases rate of progression of dysplasia in those who develop Barrett’s esophagus.”

The study received no outside funding. Lead author Dr. Qumseya had no financial conflicts to disclose. Dr. Ketwaroo serves on the GI & Hepatology News editorial advisory board.

Background: After a first episode of CDI, almost 20% of patients will have a recurrence. Recurrent CDI (rCDI) is more likely to be associated with life-threatening complications including toxic megacolon, perforation, bloodstream infections, and death. Most BSIs are caused by intestinal microbes. Some evidence suggests that vancomycin therapy creates conditions that favor intestinal colonization by health care–associated pathogens. FMT aims to restore the normal composition of gut microbiota, is superior to vancomycin, and might decrease the incidence of BSI and related complications including death.

Five patients in the FMT group and 40 in the antibiotic group (16% of total patients) developed BSIs during the 90-day follow-up. Because of baseline characteristic differences in the patients treated with FMT versus antibiotics, comparative analyses were limited to the matched cohort. Risk for BSIs was 23% lower in the FMT group (95% confidence interval, 10%-35%); the FMT group also had 14 fewer days of hospitalization (95% CI, 9-20 fewer days) and a 32% increase in overall survival (95% CI, 16%-47%), compared with the antibiotic group. Limitations of the study include its observational nature, single-center design, and differences in several baseline characteristics between the groups remaining after the match.

Bottom line: Patients with rCDI who received FMT were less likely to develop primary BSIs and related complications, including hospital length of stay and death when compared with patients who received antibiotics.

Background: After a first episode of CDI, almost 20% of patients will have a recurrence. Recurrent CDI (rCDI) is more likely to be associated with life-threatening complications including toxic megacolon, perforation, bloodstream infections, and death.

The Centers for Disease Control and Prevention is finalizing new guidelines to help clinicians diagnose and manage long COVID, or postacute sequelae of SARS-CoV-2 infection.

In a day-long congressional hearing on April 28, John Brooks, MD, a medical epidemiologist at the CDC’s division of HIV/AIDS prevention, testified that the guidelines were going through the clearance process at the agency, but would be forthcoming.

“They should be coming out very shortly,” Dr. Brooks said.

The guidelines, which were developed in collaboration with newly established long-COVID clinics and patient advocacy groups, will “illustrate how to diagnose and begin to pull together what we know about management,” of the complex condition, he said.

For many doctors and patients who are struggling to understand symptoms that persist for months after the initial viral infection, the guidelines can’t come soon enough.

National Institutes of Health Director Francis Collins, MD, PhD, who also testified at the hearing, estimated that as many as 3 million people could be left with chronic health problems after even mild COVID infections.

“I can’t overstate how serious this issue is for the health of our nation,” he said.

Dr. Collins said his estimate was based on studies showing that roughly 10% of people who get COVID could be affected by this and whose “long-term course is uncertain,” he said. So far, more than 32 million Americans are known to have been infected with the new coronavirus.

“We need to make sure we put our arms around them and bring answers and care to them,” said Rep. Anna Eshoo (D-Calif.), chairwoman of the Subcommittee on Health.

Jennifer Possick, MD, who directs the post-COVID recovery program at Yale New Haven (Conn.) Hospital, testified that the tidal wave of patients she and her colleagues were seeing was overwhelming.

“We are a well-resourced program at an academic medical center, but we are swamped by the need in our community. This year, we have seen more patients with post COVID-19 conditions in our clinic alone than we have new cases of asthma and COPD combined,” she said. “The magnitude of the challenge is daunting.”

Dr. Possick estimated that there are “over 60” clinics in the United States that have started to treat long-COVID patients, but said they are grassroots efforts and all very different from each other.

“Whoever had the resources, had the time, [and] was able to take the initiative and forge to the relationships because most of them are multidisciplinary, did so,” she said.
 

Patients testify

Several representatives shared moving personal stories of loved ones or staffers who remained ill months after a COVID diagnosis.

Rep. Ann Kuster, from New Hampshire, talked about her 34-year-old niece, a member of the U.S. Ski Team, who had COVID just over a year ago and “continues to struggle with everything, even the simplest activities of daily living” she said. “She has to choose between taking a shower or making dinner. I’m so proud of her for hanging in there.”

Long-COVID patients invited to testify by the subcommittee described months of disability that left them with soaring medical bills and no ability to work to pay them.

“I am now a poor, Black, disabled woman, living with long COVID,” said Chimere Smith, who said she had been a school teacher in Baltimore. “Saying it aloud makes it no more easy to accept.”

She said COVID had affected her ability to think clearly and caused debilitating fatigue, which prevented her from working. She said she lost her vision for almost 5 months because doctors misdiagnosed a cataract caused by long COVID as dry eye.

“If I did not have a loving family, I [would] be speaking to you today [from] my car, the only property I now own.”

Ms. Smith said that long-COVID clinics, which are mostly housed within academic medical centers, were not going to be accessible for all long-haulers, who are disproportionately women of color. She has started a clinic, based out of her church, to help other patients from her community.

“No one wants to hear that long COVID has decimated my life or the lives of other black women in less than a year,” Ms. Smith said. “We’ve just been waiting and hoping for compassionate doctors and politicians who would acknowledge us.”

Key clinical point: The addition of palbociclib to estrogen therapy for 1 year does not improve invasive disease-free survival (DFS) in high-risk patients with hormone-receptor–positive (HR+), human epidermal growth factor receptor (HER)-negative early breast cancer who had residual invasive disease after neoadjuvant chemotherapy.

Major finding: Palbociclib did not improve invasive DFS vs. placebo (stratified hazard ratio, 0.93; P = .525) after a median follow-up of 42.8 months. Incidences of grade 3-4 neutropenia and leukopenia were significantly higher in the palbociclib group. Eight fatal serious adverse events were reported.

Study details: A phase 3, double-blind, randomized PENELOPE-B study evaluated 1,250 high-risk patients with HR+, HER-negative early breast cancer who have residual invasive disease after neoadjuvant chemotherapy. Patients received estrogen therapy with either palbociclib or placebo.

Disclosures: The study was supported by Pfizer. The authors declared receiving consulting, honoraria, travel/accomodation expenses and research funding outside the study work. Some of the authors declared being employee of and/or stocks/ownership interests of various sources including Pfizer.

Interestingly the authors propose possible causative mechanisms. They note that normal pancreatic secretion is regulated by neural and endocrine control mechanisms that require intact gastro-pancreatico-duodenal anatomy. Disruptions to this include “extensive pancreatic denervation because of lymph node dissection and truncal vagotomy, the asynchronous release of pancreatic enzymes for food particles (pancreaticocibal-asynchrony) because of newly made reconstructions, and gastric reservoir and neural gastric stimulation losses.” They also include the possibility of effects of adjuvant therapies as well. 

While 64% of this patient population had some form of EPI, another study from this month’s selection by Sridhar et al out of Vellore, India tells a different story. In this cross-sectional study, they looked at symptomatic and biochemical evidence of EPI on pre and post questionnaires following gastric resection for adenocarcinoma. Of 27 patients that completed pre and post questionnaires, none of the patients on short-term follow-up (mean follow up of 3 months) had clinical symptoms of EPI following gastric resection. However, more than a third of the patients developed asymptomatic EPI after gastric resection, based on FE testing. The authors conclude that pancreatic supplementation might not be necessary following gastric resection, but perhaps their follow up window was much too short to draw such a conclusion.

Key clinical point: Increasing body mass index (BMI) among survivors of early breast cancer is associated with a higher risk of developing a second primary cancer.

Major finding: At a mean follow-up of 88.0 months, 12.7% of patients developed a second primary cancer. For every 5 kg/m² increase in the BMI, the risk for any second cancer diagnosis increased by 7% and for obesity-related cancers by 13%. The risk for a second breast cancer and second estrogen receptor-positive breast cancer increased by 11% and 15%, respectively, for every 5 kg/m² increase in the BMI.

Study details: A retrospective cohort study of 6,481 women with early-stage primary breast cancer, wherein 33.4% of patients were overweight, and 33.8% were obese.

Disclosures: This work was supported in part by the Intramural Research Program of the Division of Cancer Epidemiology and Genetics of the US National Cancer Institute, and American Cancer Society. The authors disclosed no conflict of interests.

Key clinical point: High rates of sentinel lymph node biopsy (SLNB) and radiotherapy (RT) do not show benefit in older women with early estrogen receptor-positive (ER+) breast cancer.

Major finding: Among all patients, 65.3% received SLNB and 54.4% received adjuvant RT. No association was found between SLNB and locoregional recurrence-free survival (LRFS; P = .71) or disease-free survival (DFS; P = .11). RT showed no association with LRFS (P = .10) or DFS (P = .97).

Study details: A retrospective cohort study of 3,361 consecutive patients aged 70 years or older with early ER+ breast cancer.
