A Case of Capillary Leak Syndrome and Intestinal Ischemia Caused by Rheumatoid Vasculitis

Rheumatoid vasculitis (RV) is a rare disease associated with rheumatoid arthritis (RA). The incidence of RV has decreased with the development of treatment for RA. However, some patients still develop RV in rural areas, where medical care for autoimmune diseases is inadequate. In this report, we describe a case of RV complicated by an acute exacerbation of generalized ulcerative lesions and capillary leak syndrome in an 86-year-old woman with a severe joint deformity due to RA. RV is a systemic vasculitis characterized by various symptoms. When a patient with RA is diagnosed with poorly controlled joint deformities, general physicians should consider the possibility of RV. Urgent investigation and intensive treatment should be initiated for vasculitis to support the lives of older patients with advanced RA.
