Abstract: Objective To investigate the condition of glucose metabolism in hepatitis B virus (HBV) carrier
complicated with gestational diabetes mellitus (GDM) during pregnancy and postpartum, and to analyze the
effects of HBVcarrying on the outcomes of GDM. Methods Clinical data of 64 HBV carrier complicated
with GDM were collected and analyzed, retrospectively. All patients completed their prenatal examination
and delivery in Beijing Ditan Hospital, Capital Medical University from January 2013 to July 2014.
Fasting plasma glucose (FPG), 2 hour plasma glucose (2hPG) and fasting insulin (FINS) were examined in
24~28 weeks of pregnancy, 6~8 weeks and 1 year after delivery. The homeostasis model assessment of
insulinresistance (Homa-IR), homeostasis model assessment of insulin sensitivity (Homa-ISI), homeostasis
model assessment of percent β cell function (Homa-β) were calculated by homeostasis model assessment
(HOMA). The changes of glucose, insulin, insulin sensitivity and function of pancreatic β cell were compared
at different times. Results The FPG, 2hPG and FINS of 6~8 weeks and 1 year after delivery were lower
than those of 24~28 weeks of pregnancy (P < 0.05). But there was no statistical difference between 6~8
weeks and 1 year after delivery [95%CI: (-0.319, 0.163), (-3.137, -2.143), (0.075, 3.143); P = 0.523, 0.333,
0.245]. The Homa-β of 6~8 weeks and 1 year after delivery, and Homa-ISI of 6~8 weeks after delivery
were higher than those of 24~28 weeks of pregnancy (Z = -4.4484, -3.965; P < 0.001). There were no
statistical differences of Homa-IR among three groups (Z = -2.049, P < 0.001), and there were also no
statistical differences of Homa-ISI and Homa-β between 6~8 weeks and 1 year after delivery (P > 0.005).
Conclusions The secreted function of pancreatic β cell in HBV carrier complicated with GDM recovered
gradually and the level of insulin increased after delivery, but insulin resistance still existed. The rate of new
abnormal glucose metabolism after delivery is increasing as time going on.
