Antiphospholipid syndrome, disease activity, tobacco consumption and socio-economic status strongly impact fetal outcomes during SLE pregnancy.
HCQ may reduce IUGR and preterm delivery in SLE pregnancy.
The efficacy of HCQ in the prevention of prematurity as well as IUGR during SLE pregnancies is not confirmed in this meta-analysis.
Our results should be interpreted with caution because of the heterogeneity of the studies and should not discourage the use of HCQ in this context.
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that primarily affects women of childbearing age. While the impact of hydroxychloroquine (HCQ) on SLE activity and neonatal lupus occurrence has been evaluated in several studies, its role on prematurity and intrauterine growth restriction (IUGR) remains uncertain. The aim of this study was to assess the impact of HCQ exposure on prematurity and IUGR during pregnancy in women with SLE.
We conducted a systematic review and a meta-analysis comparing prematurity and IUGR in SLE pregnancies exposed or not exposed to HCQ. The odds ratio of IUGR and prematurity were calculated and compared between pregnancies in each group according HCQ treatment.
Six studies were included (3 descriptive cohort studies and 3 case series) totalling 870 pregnancies. Of the SLE pregnancies, 308 were exposed to HCQ and were compared to 562 not exposed to HCQ. There was no statistical difference for prematurity or IUGR between groups.
This meta-analysis failed to prove the efficacy of HCQ in the prevention of prematurity as well as IUGR during SLE pregnancies. Due to the heterogeneity of the studies, these results should be interpreted cautiously.El texto completo de este artículo está disponible en PDF.
