Abstract

Vasculitides, particularly those affecting small vessels, are known to complicate systemic lupus erythematosus (SLE); however, isolated venulitis of the mesenteric bed has rarely been reported. Here we relate the case of a 46-year-old woman with SLE who presented with acute abdominal pain due to artery thrombosis and extended splenic ischemia requiring splenectomy. The histological examination revealed diffuse venulitis in the absence of arterial vasculitis consistent with the definition of mesenteric inflammatory veno-occlusive disease (MIVOD). Furthermore, arterial wall thickening suggestive of uncomplicated atherosclerosis was observed. Two months later, the patient suffered of severe myocardial infarction (MI) resulting from thrombosis of the anterior interventricular coronary artery with otherwise no signs of coronary disease at coronarography. Extensive work-up to establish the cause of MI was negative, with the exception of marginal, isolated and transient elevation of cardiolipin IgG (14.5 GPL, n.v. 0-5 GPL). This patient's SLE history is dramatically marked by the previously non-described association of MIVOD and two arterial thrombotic events (splenic and coronary) occurring within a two months period, and stresses the need of better understanding and prevention of vascular complications in SLE.
