Researchers from the Toronto Lupus Clinic have described an atypical “monophasic” course in a small number (7.5%) of systemic lupus erythematosus (SLE) patients who achieved and sustained clinical remission, with most off of all medications for an average of 18 years.

Their inception SLE cohort includes patients enrolled within 18 mos of diagnosis.

Today the U.S. Food and Drug Administration approved baricitinib (Oluminant) at the lower dose of 2 mg per day for use in adults with with moderate-to-severe active rheumatoid arthritis (RA) who have had an inadequate response to commonly-used treatments known as TNF inhibitors.

de Winter and colleagues from the Netherlands have reported on magnetic resonance imaging of the sacroiliac joints of healthy subjects, patients with axial spondyloarthritis, runners and those with chronic back pain, and found a high incidence of sacroiliitis in many, but that deep bone marrow edema was most specific for those with axial SpA.

A meta-analysis has suggested that obesity is an under-reported predictor of inferior response to tumor necrosis factor blockade (anti-TNF) in a range of inflammatory immune-mediated inflammatory diseases (IMIDs), with the results showing a 60% risk of impaired response to anti-TNF across several IMIDs. Surprisingly, however, inflammatory bowel disease (IBD) appeared to be the exception to the obesity-response effect.

Patients with psoriatic arthritis (PsA) were at increased risks for malignancy, and possibly more so if they were treated with conventional disease-modifying antirheumatic drugs (DMARDs), a meta-analysis found.

In nine cohort studies that included more than 43,000 PsA patients, the pooled relative risk for overall malignancy was 1.29 (95% CI 1.04-1.60) compared with the general population, according to Yunyun Fei, MD, and colleagues from Peking Union Medical College in Beijing.
