['To examine the association between fatty acid binding protein 4 (FABP4) and pre-eclampsia risk in women with type 1 diabetes.', "Serum FABP4 was measured in 710 women from the Diabetes and Pre-eclampsia Intervention Trial (DAPIT) in early pregnancy and in the second trimester (median 14 and 26 weeks' gestation, respectively).", 'FABP4 was significantly elevated in early pregnancy (geometric mean 15.8 ng/mL [interquartile range 11.6-21.4] vs. 12.7 ng/mL [interquartile range 9.6-17]; P < 0.001) and the second trimester (18.8 ng/mL [interquartile range 13.6-25.8] vs. 14.6 ng/mL [interquartile range 10.8-19.7]; P < 0.001) in women in whom pre-eclampsia later developed. Elevated second-trimester FABP4 level was independently associated with pre-eclampsia (odds ratio 2.87 [95% CI 1.24-6.68], P = 0.03). The addition of FABP4 to established risk factors significantly improved net reclassification improvement at both time points and integrated discrimination improvement in the second trimester.'] Does serum Fatty Acid Binding Protein 4 ( FABP4 ) predict Pre-eclampsia in Women With Type 1 Diabetes?
