Pregnancy Outcomes in Takayasu Arteritis Patients
Abstract BackgroundsTakayasu Arteritis (TAK) is a chronic inflammatory autoimmune disease with a high prevalence in women of child-bearing age. We aim to investigate the maternal complications and pregnancy outcomes in patients with TAK and identify the related factors.MethodsA total of 110 pregnancies in 80 TAK patients in a Chinese TAK patient cohort and 440 matched pregnancies in healthy women between 2000 to 2020 were included. The maternal complications and pregnancy outcomes between TAK patients and matched controls were compared by chi-square test. The logistic regression analysis was used to identify the risk factors of maternal complications and adverse pregnancy outcomes in patients with TAK.ResultsMaternal complications and adverse pregnancy outcomes were more frequent in pregnancies with TAK than that in healthy women (P<0.001). In pregnancies with TAK, the most common maternal complication was new-onset or worsening of hypertension (18.2% [20/110]) and the most prevalent obstetrical complication was spontaneous abortion (32.7% [36/110]). Hypertension (OR 5.01, 95% CI 1.61 to 16.01), heart disease (OR 15.83, 95% CI 1.99 to 125.99), and active TAK (OR 7.54, 95% CI 1.85 to 30.72) before pregnancy were independently associated with increased maternal complications. The disease duration (OR 1.12, 95% CI 1.02 to 1.23) and active disease during pregnancy (OR 14.59, 95% CI 1.81 to 117.49) were correlated with adverse pregnancy outcomes. ConclusionTAK disease itself is a risk factor for adverse pregnancy outcomes. Treating the disease to a stable state before and after pregnancy, and close collaboration between rheumatologists and obstetricians are important measures to reduce maternal complications and reach favorable pregnancy outcomes.
