The role of complement factor H in gestational diabetes mell
Complement factor H (CFH) has been found to be associated with insulin resistance. This study assessed the correlation between CFH and other clinical parameters and determined whether CFH played a role in gestational diabetes mellitus (GDM) and adverse pregnancy outcomes.

A total of 397 pregnant women were included for analysis in this nested case-control study. Clinical parameters and serum were collected within the 11-17th gestational age at the first prenatal visit. At 24–28 weeks of gestation, a 75 g oral glucose tolerance test was performed and subjects were divided into a GDM and a non-GDM control group. The delivery data were also followed. The serum CFH level was assayed by ELISA.

- CFH was higher in GDM than in non-GDM controls. CFH level was moderately associated with pre-pregnancy body mass index (BMI), BMI, and total triglycerides (TG), and slightly associated with gestational age, low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC) in GDM and non-GDM.

- Moreover, CFH level was moderately correlated with alkaline phosphatase (ALP) and slightly correlated with age, uric acid (UA), and total bilirubin (TB) in non-GDM.

- After adjustment for clinical confounding factors, BMI, TG, gestational age, ALP, TB, age and UA were independent risk factors for log10 CFH levels in all subjects.

- In addition, overweight or obese pregnant women, women with hypertriglyceridemia, and women in the second trimester had significantly higher CFH levels than the normal weight and underweight group, the non-hypertriglyceridemia group, and women in the first-trimester group in all pregnant women respectively.

- Following binary logistic regression, CFH was not independently associated with GDM and related pregnant outcomes.

The CFH in 11-17th weeks of gestation might be affected by many factors, including BMI, TG, gestational age, ALP, TB, age, and UA. CFH was not an independent risk factor for GDM and adverse pregnancy outcomes.
