Clinical Trial Summary

To explore the impact of chronic pancreatitis (CP) susceptibility genes on pregnancy outcomes.

Description:

The goal of this observational study is to explore the impact of CP susceptibility genes (SPINK1, PRSS1, CTRC, CFTR) on pregnancy outcomes (including both maternal and fetal outcomes) in a large Chinese cohort. Participants will be asked to provide their pregnancy-related data.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	adverse maternal outcomes of female CP patients	CP-associated caesarean delivery referred to caesarean deliveries which happened due to the attack of CP or comorbidities associated with CP such as GDM and HDP.; CP-associated preterm delivery was defined as preterm deliveries which happened due to the attack of CP or comorbidities associated with CP.; GDM was defined as the onset or first recognition of abnormal glucose tolerance during pregnancy.; Intrahepatic cholestasis of pregnancy was based on characteristic symptoms, as well as elevated serum bile acids, in the absence of other hepatobiliary disease.; HDP included preeclampsia/eclampsia, chronic hypertension, chronic hypertension with superimposed preeclampsia, and gestational hypertension.	through study completion, an average of 1 year
Primary	adverse fetal outcomes of female CP patients	Low birth weight was defined as weight at birth <2500 g.; CP-associated abortion referred to abortions (i.e., a nonviable intrauterine pregnancy up to 20 weeks' gestation) which happened due to the attack of CP or comorbidities associated with CP.; Congenital anomaly referred to the inborn errors of development.; Stillbirth was defined as the delivery of a fetus =20 weeks of gestation with no signs of life.	through study completion, an average of 1 year
