PURPOSE OF REVIEW: Pregnancies in women with antiphospholipid antibodies (aPL) are associated with several pregnancy complications. The current treatment to prevent obstetric aPL-mediated morbidity is largely based on low-dose aspirin (LDA) and low-molecular-weight heparin (LMWH). Alternative treatment regimens to prevent obstetric aPL-related morbidity include the addition of the antimalarial hydroxychloroquine (HCQ). The aim of this systematic review is to identify the currently available evidence on the efficacy of HCQ to prevent aPL-related obstetric morbidity. RECENT FINDINGS: We identified four retrospective observational studies. No definite signal of harm was identified as none of the studies reported adverse outcomes. When comparing a total of 214 aPL-positive women with a total of 250 HCQ-exposed aPL-positive pregnancies and 521 pregnancies not exposed to HCQ, we found that HCQ exposure was not associated with an increased rate of live births [pooled OR 1.33; 95% confidence interval (CI) 0.62--2.86]). There was considerable heterogeneity in the analysis (I = 59%). SUMMARY: HCQ seems well tolerated in pregnancy. However, because of the heterogeneity of available studies, the questions whether women with aPL (or some subpopulation of those) might benefit from this agent during pregnancy remains unanswered. Randomized controlled data are needed.
