Familial Mediterranean fever (FMF) is an autosomal recessive condition characterized by periodic attacks of fever, aseptic serositis and synovitis. In this study, we investigated maternal and neonatal outcomes in pregnant patients with FMF. This retrospective study consisted of 46 pregnant patients with FMF who attended the perinatology clinic of Dr Zekai Tahir Burak Research and Training Hospital between January 2008 and December 2012. The following clinical and demographic data were obtained by reviewing the patients' medical records: maternal age, colchicine use during pregnancy, obstetric history, pregnancy outcome and maternal and neonatal complications during the current pregnancy. The patients with FMF had higher rates of premature rupture of membranes (PROM) and Cesarean delivery as well as low birth weight infants; however, rates of stillbirth, gestational diabetes, preeclampsia did not differ between the groups. Preterm delivery rates were higher in the study group, but this difference did not reach statistical significance. Patients with pregnancy complications had significantly more basal proteinuria than did patients without complications. Nine patients did not receive colchicine therapy in the previous or current pregnancies. Within this subgroup, four (44.4%) of the patients had a history of two or more previous miscarriages. However, there were only three cases (8.1%) of two or more miscarriages among 37 patients who received colchicine; this difference was statistically significant FMF leads to higher rates of PROM, recurrent miscarriage and preterm deliveries. Colchicine treatment is safe in pregnancy and may lead to a decreased miscarriage rate.
