The Additional use of hydroxychloroquine can improve the live birth rate in pregnant women with persistent positive antiphospholipid antibodies: A systematic review and meta-analysis.

Abstract

PURPOSE\nTo evaluate the efficacy of additional treatment with hydroxychloroquine (HCQ) for pregnant women with persistent positive antiphospholipid antibodies or antiphospholipid antibody syndrome (APS).\n\n\nMETHOD\nWe conducted a systematic search of the PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials databases from inception to 31th December 2019. Two authors performed study selection, data collection, and data analysis independently.\n\n\nRESULT\nFive retrospective studies involving 477 pregnancies were selected. The live birth rate was significantly improved in the experimental group (OR, 3.29; 95% CI, 1.45-7.49; P\u2009=\u20090.004). Additionally, pregnancy loss was associated with the additional use of HCQ (OR, 0.30;95% CI, 0.13-0.69; P\u2009=\u20090.004). However, HCQ had no significant association with preterm delivery (OR, 0.43; 95% CI, 0.13-1.37; P\u2009=\u20090.16) and fetal growth restriction showed an OR of 0.22 (95% CI, 0.13-1.88; P\u2009=\u20090.55).\n\n\nCONCLUSION\nThese data suggest that receiving HCQ as an additional treatment can improve the live birth rate in pregnant women with persistent antiphospholipid antibodies.
