Severe and fatal outcomes with coronavirus infection are often the result of the downstream damage that follows the viral infection. Rising high on the list of complications are the hematologic and vascular complications seen in severely affected patients, so much so that many centers are routinely anticoagulating hospitalized (but not ambulatory) COVID patients.

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.

While it is often said there is a negative association between gout and rheumatoid arthritis (RA), cases of coexistent disorders are uncommonly seen. A recent VA study describes 121 patients whith both RA and gout.

Patients with the idiopathic inflammatory myopathies (IIMs) dermatomyositis and polymyositis are at increased risk for cardiovascular events, with risks similar to what has been documented for rheumatoid arthritis (RA), during the first 5 years after diagnosis, U.K. researchers reported.

The VITAL study is a VA registry that has shown that both systemic lupus erythematosus  (SLE) and rheumatoid arthritis (RA) patients carry higher odds of both premature and extremely premature atherosclerotic cardiovascular disease and its consequences.

Two recent reports further characterize the newly described, Kawasaki-like,  syndrome affecting children with COVID-19 infections.

The NEJM describes the childhood syndrome as having Kawasaki’s disease, fever, toxic shock syndrome, acute abdominal conditions, and encephalopathy; hence the label Childhood Multisystem Inflammatory Syndrome. The disorder emerged in late April 2020, first in the U.K., and then similar cases were reported from many other countries. The CDC named this multisystem inflammatory syndrome in children (MIS-C).

Multisystem inflammatory syndrome in children (MIS-C) associated with COVID-19 infection has both similarities and differences with Kawasaki disease, and requires distinct clinical management, according to draft guidance from the American College of Rheumatology (ACR).
