Among patients with rheumatoid arthritis (RA), the strongest risk factors for the development of lymphoma were disease activity and severity, French researchers found.

In a multivariate analysis, having a high Disease Activity Score in 28 joints (DAS28) at baseline conferred twice the risk for lymphoma, with an odds ratio of 2.09 (95% CI 1.41-3.38), according to Gaetane Nocturne, MD, of Hôpital Bicêtre in Ile-de-France, and colleagues.

2020 was historic, memorable and game-changing. Under the cloud of COVID-19, there were many significant and memorable advances and setbacks for the rheumatology world. In our accounting of most read articles for 2020, (not surprisingly) 17/20 were COVID-related.

Neuropsychiatric (NP-SLE) or CNS lupus events range from mild to severe; several recent studies have noted that NPS lupus is common and should be screened for.

A metanalysis of the literature finds 22 studies wherein the mean frequency of NPSLE ranged from 10.6% to 96.4%. When researchers with the Swiss SLE cohort study looked at their population, NPSLE was found in 28.1%. This included cerebrovascular insults, seizures and psychosis.

The NEJM has published results of a real-world efficacty trial showing that COVID infected children with the multisystem inflammatory syndrome in children (MIS-C) respond better to initial IVIG plus glucocorticoids (than IVIG alone) which was associated with less subsequent cardiovascular co
