Abstract
BACKGROUND Despite recommendations to use inhaled corticosteroids as treatment to control asthma during pregnancy, it is unknown whether inhaled fluticasone propionate (FP) reaches the fetus. Results & methodology: We collected maternal blood on the morning following delivery. FP was detected by ultra-performance LC-MS/MS (UPLC-MS/MS) in 9/17 asthmatic women using FP. Delay between last FP inhalation and maternal blood sampling ranged between 3 and 33 h and FP was detected in a range of 1.572-46.440 pg/ml. Among the nine offspring of these FP users, FP was detected in five cord blood samples. Delay between last predelivery FP inhalation and cord blood sampling ranged from 4 to 20 h and FP was detected in a range of 0.423-4.510 pg/ml. CONCLUSION Our findings demonstrate placental passage of inhaled FP.

Abstract
OBJECTIVE The lifetime risk of metabolic diseases in offspring of women with gestational diabetes mellitus (GDM) depends, at least in part, on the impact of glycemic fetal programming. To quantify this impact, we have developed and validated a unique mass spectrometry method to measure the percentage of glycated hemoglobin in cord blood. RESEARCH DESIGN AND METHODS This case-control study includes 37 GDM women and 30 pregnant women with normal glucose tolerance (NGT). RESULTS Glycation of the α-chain (Glα) was higher in neonates from GDM (2.32 vs. 2.20%, P < 0.01). Glα strongly correlated with maternal A1C measured at delivery in the overall cohort (r = 0.67, P < 0.0001) as well as in each group (GDM: r = 0.66, P < 0.0001; NGT: r = 0.50, P = 0.01). CONCLUSIONS Thus, Glα may reflect hyperglycemic exposure during the last weeks of fetal development. Future studies will confirm Glα is a predictive biomarker of prenatally programmed lifetime metabolic health and disease.
