Relationship between remote cholecystectomy and incident Clostridioides difficile infection.


ABSTRACT: OBJECTIVES:Cholecystectomy (CCY) is associated with increased faecal levels of secondary bile acids. Secondary bile acids confer resistance to Clostridioides difficile infection (CDI, formerly Clostridium difficile infection) in animal studies. This study tested the hypothesis that CCY confers protection against CDI by increasing gut levels of secondary bile acids. METHODS:This was a retrospective case-control study. Adults hospitalized between January 2010 and June 2017 at our institution were included. CDI cases were defined as a positive stool PCR followed by anti-CDI treatment and were matched 1:1:1 with two control groups (those who tested negative for CDI and those who were not tested for CDI) by sex, age group, body mass index (BMI), and exposure to antibiotics. CCY was defined as a history of CCY at least 6 months prior to the index C. difficile test or the index admission date in the untested controls. Conditional logistic regression modelling was used to estimate the relationship between remote CCY and risk for CDI. RESULTS:The final study population was 7077 (2359 CDI cases, 2359 matched controls without CDI, and 2359 matched controls not tested for CDI). Rates of remote CCY did not differ among the three groups (14.4% vs. 15.5% vs. 14.2%) and this result was unchanged after adjusting for additional clinical factors (adjusted OR 0.90, 95% CI 0.76-1.06 comparing CDI cases vs. matched controls without CDI; adjusted OR 1.04, 95% CI 0.78-1.39 comparing CDI cases vs. matched controls not tested for CDI). CONCLUSIONS:There was no association between remote CCY and risk for CDI.
