Patients with rheumatoid arthritis (RA) who were obese were significantly less likely to remain on treatment with tumor necrosis factor (TNF) inhibitors -- but so were those who were underweight, a large, long-term study determined.

Compared with patients with normal weight, patients in obesity class II, whose body mass index (BMI) was 35 to 39.9, had a hazard ratio for shorter drug survival (i.e., the drug's effectiveness, safety, and tolerability) of 1.28 (95% CI 1.06-1.54), while those in obesity class III, whose BMI exceeded 40, had a hazard ratio of 1.67 (95% CI 1.29-2.18), according to Sytske Anne Bergstra, PhD, of Leiden University Medical Center in the Netherlands, and colleagues.

Pain management in knee osteoarthritis (OA) is confounded by studies showing less is equal to usual standards of care. A recent trial showed that meloxicam was superior to placebo or cognitive behavioral therap (CBT); although the differences were small. 

The current issue of NEJM reports a novel cell type that may be used to identify rheumatoid arthritis (RA) patients who may flare. 

Investigators prospectively collected blood samples from 4 patients for longitudinal RNA sequencing (RNA-seq) for discovery of moleculartranscripts that were differentially expressed before flares.

The oral Janus kinase (JAK) inhibitor upadacitinib (Rinvoq) given as monotherapy was more effective than methotrexate alone in methotrexate-naive patients with active rheumatoid arthritis (RA) in a multinational phase III trial.

Hydroxychloroquine is one of many medications frequently used in rheumatology practice. Its remarkable versatility is attested by its routine use in lupus, in patients with an autoimmune coagulopathy, in patients with rheumatoid arthritis, as well as in those with a low-level inflammatory arthropathy.
