Vascular- and pregnancy-related outcomes in patients with systemic lupus erythematosus with positive antiphospholipid profile and thrombocytopenia.

This study aimed to investigate whether patients with lupus and a positive antiphospholipid profile with thrombocytopenia are at a higher risk for obstetric complications or thrombotic events than patients without thrombocytopenia. We conducted a case-control study matched 3:1 by sex, age of systemic lupus erythematosus diagnosis, age at study start, disease duration and length of follow-up time. Time to first event following study start was compared using Kaplan-Meier curves and log-rank tests and it was not statistically significant. In this study setting and population, thrombocytopenia was not associated with a higher risk for obstetrical complications or thrombotic events.
