POS1336 BEHCET’S DISEASE AND PREGNANCY OUTCOMES

Abstract

BackgroundBehcet’s disease (BD) is multisystemic disease of unknown cause. The relationship between BD and pregnancy is reported in limited number of studies.ObjectivesTo evaluate outcomes of pregnancies in BD patients (pts).MethodsWe retrospectively collected data of 45 women with BD diagnosis (according to ISGBD 1990 and ICBD 2014) and their 118 pregnancies. Pts’ mean age was 31,3 [27;35] years., disease duration 6,0 [3;8] years. 11,1% pts had severe BD according to Ch.Zouboulis classification (due to generalized uveitis, retinal vasculitis and parenchymatous CNS lesions), 31,1% pts had a moderate disease, 57,8% pts had a mild disease with mainly dermal-mucous manifestations.Results118 pregnancies in 35 pts resulted in 75 live birth (6 cesarean section in 3 pts). Thirty-nine incomplete pregnancies were observed in 26 patients. Ten patients had 20 medical abortions on request before 12 weeks of gestation, one patient had an abortion due to medical reasons (rubella on the 7 th week of gestation), two patients had premature birth at 28 and 32 weeks with subsequent perinatal death of the baby. Fifteen out of 35 pts had 20 adverse pregnancy outcomes: 8 spontaneous abortion, 12 missed miscarriage. Nine patients had 12 Missed miscarriage at 6-11 weeks of gestation, one patient had 3 missed miscarriage, two had 2, and the others had 1 missed miscarriage. Six patients had 8 spontaneous abortions (early miscarriage). In the control group of 15 women, 7 had 15 pregnancies, 13 live birth of healthy children on time. Table 1 presents a comparison of pregnancy outcomes in patients with BD and healthy control.Table 1.Pregnancy outcomesPregnancy, nBD, n=118 (%)Control, n=15 (%)pBirth77 (65)13 (87)0,01Abortion21 (18)00,00Unfavorable pregnancy outcome20 (17)2 (13)nsMissed miscarriage12 (10)0nsSpontaneous abortion8 (7)2 (13)nsPatients with BD were more likely to terminate pregnancy of their own volition compared to control group. All women with unfavorable pregnancy outcomes are re-pregnant, have healthy children born on time, all had a second or subsequent pregnancy with an unfavorable outcome. Immunosuppressive therapy of BD was not received by any of the pregnant women, which makes it possible to exclude the connection of the outcome of pregnancy with BD therapy.The manifestation of BD with skin-mucous lesion of the patient in the first and third trimester of pregnancy was noted by 3 patients. In one patient, the appearance of a recurrent ulcer on the vulva was an indication for cesarean section.Only three women had one favorably completed pregnancy, all the others had from 2 to 7 pregnancies. Out of 45 patients, 10 patients did not have pregnancies, 9 of them are not married, 1 patient is planning a pregnancy.Table 2 shows the frequency of pregnancy pathology with varying degrees of severity of BD.ConclusionPatients with BD were more to terminate pregnancy compared to control group. Unfavorable outcomes of pregnancy were documented in pts regardless (with all grades of) BD severity.
