Pregnancy outcome in women with cystic fibrosis and poor pulmonary function

Abstract: Background To investigate how poor pre-gestational pulmonary function influenced pregnancy outcome and clinical status evolution in women with cystic fibrosis. Methods Pregnancies in women without lung transplantation with a first delivery reported to the French cystic fibrosis registry between 2000 and 2012 were identified. Pregnancy outcomes and clinical trends (body mass index – BMI, and pulmonary function) over a 4-year follow-up in women with poor pre-gestational pulmonary function, defined as forced expiratory volume (FEV 1 ) ≤ 50%, were compared to those in women with FEV 1 ˃ 50%. Results A total of 149 women had a first delivery and 36 (24.2%) of these had pre-gestational FEV 1 ≤ 50%. There was no significant difference in age or frequency of assisted conception between the 2 groups. The rate of cesarean section was significantly higher in women with FEV 1 ≤ 50% (43.7% vs. 21.1%, p = .01). The frequency of preterm birth did not differ significantly between the two groups, but median infant birthweight was significantly lower in women with FEV 1 ≤ 50% (2705 g; range: 650–3700 vs. 3044 g; range: 1590–3860, p = .003). Despite significantly lower FEV 1 and BMI the year before pregnancy for women with poor pulmonary function, the decline in these parameters during the study period did not differ significantly between the two groups. Conclusion Poor pre-gestational pulmonary function in women with cystic fibrosis was associated with a higher rate of cesarean section and a clinically significant impact on fetal growth, but was not associated with more important pulmonary and nutritional decline over the study period.
