Genetic Factors Associated With Adverse Pregnancy Outcomes in Chronic Pancreatitis

INTRODUCTION

The effects of genetic factors on pregnancy outcomes in chronic pancreatitis (CP) patients remain unclear. We evaluated the impacts of clinical features and mutations in main CP-susceptibility genes ( SPINK1 , PRSS1 , CTRC , and CFTR ) on pregnancy outcomes in Chinese CP patients.

METHODS

This was a prospective cohort study with 14-year follow-up. The sample comprised female CP patients with documented pregnancy and known genetic backgrounds. Adverse pregnancy outcomes were compared between patients with and without gene mutations. Univariate and multivariate analyses were performed to determine the impact factors for adverse pregnancy outcomes.

RESULTS

Totally, 160 female CP patients with a pregnancy history were enrolled; 59.4% of patients carried pathogenic mutations in CP-susceptibility genes. Adverse pregnancy outcomes occurred in 38 patients (23.8%); the prevalence of adverse outcomes was significantly higher in those harboring gene mutations than those without (30.5% vs 13.8%, P = 0.015). Notably, the rates of preterm delivery (12.6% vs 3.1%, P = 0.036) and abortion (17.9% vs 4.6%, P = 0.013) were remarkably higher in patients with gene mutations (especially SPINK1 mutations) than those without. In multivariate analyses, both CP-susceptibility gene mutations (odds ratio, 2.52; P = 0.033) and SPINK1 mutations (odds ratio, 2.60; P = 0.037) significantly increased the risk of adverse pregnancy outcomes. Acute pain attack during pregnancy was another risk factor for adverse pregnancy outcomes.

DISCUSSION

Pathogenic mutations in CP-susceptibility genes, especially SPINK1 , were independently related to adverse pregnancy outcomes in CP patients. Significant attention should be paid to pregnant females harboring CP-susceptibility gene mutations (ClinicalTrials.gov: NCT06055595).

Serum levels of tumor-associated trypsin inhibitor (TATI) in benign and malignant gynecological diseases

The behavior of tumor-associated trypsin inhibitor (TATI) as a marker for gynecological cancer was studied in a control population and in patients with different benign and malignant diseases. When a cut-off level of 21.4 micrograms/l was used the specificity was 100% in patients with benign diseases. The sensitivity in patients with malignant tumors was low for cervical and corpus cancer, 13% and 14%, respectively, whereas it was 33% in all the ovarian malignant tumors, reaching 60% in the mucinous type. There was a clear correlation between TATI level and stage.
