1. Aortic valve replacement improves function but may not improve quality of life

Transcatheter aortic valve replacement (TAVR) improves functional status but may not improve overall quality of life, according to an article being published in Annals of Internal Medicine. Aortic stenosis (AS) is the most common valvular heart disease in developing countries and it affects up to 3 percent of adults older than 75. In recent years, TAVR has emerged as an alternative treatment to surgical aortic valve replacement (SAVR) for high-risk or inoperable patients with symptomatic severe AS. Researchers reviewed 62 published studies to evaluate the changes in functional status and quality of life after TAVR. The research suggested that TAVR improved symptoms, physical function, and disease-specific measures of quality of life compared with conservative treatment. However, the benefits in psychological dimension and general health measures were often small and inconsistent, which may be an important consideration for older patients looking to improve quality of remaining life.

2. Rituximab may not benefit patients with primary Sjgren syndrome

Rituximab appears to offer no long term benefit to patients with primary Sjgren syndrome (pSS), according to an article published in Annals of Internal Medicine. pSS is a chronic autoimmune disorder characterized by dryness of the eyes and mouth. Up to half of patients have systemic involvement, with fatigue being a symptom associated with significant disability. No systemic treatment has been proved to significantly improve symptoms. Mounting evidence on B cell involvement in pSS suggests that B-cell depletion could be an effective treatment for pSS. The CD20 antigen, a transmembrane protein found on pre-B and mature B cells, is the most widely studied target for achieving B-cell depletion. Rituximab is an anti-CD20 antibody. Researchers conducted a multicenter, double-blind, placebo-controlled, randomized trial to evaluate the efficacy and harms of rituximab in adults with recent-onset or systemic pSS. They found that rituximab given in two infusions over two weeks alleviated some symptoms, particularly fatigue, early in the trial but did not alleviate symptoms or disease activity at 24 months. More infusion reactions occurred with rituximab than placebo. The data do not support use of rituximab for treating pSS.
