Statins and Diarrhea: Investigating the Connection
Statins and Gastrointestinal Adverse Events
Statins, widely prescribed for lowering cholesterol, have been associated with various gastrointestinal side effects, including diarrhea. A retrospective cohort study aimed to determine if statin therapy is linked to conditions like constipation, abdominal pain, diarrhea, or colitis. The study found no significant difference in the occurrence of constipation, abdominal pain, or colitis between statin users and non-users. Interestingly, the study reported decreased odds of diarrhea among statin users (OR, 0.88; 95% CI, 0.80–0.97; P = .01). This suggests that statins might not only be safe from causing diarrhea but could potentially reduce its incidence.
Statins and Clostridium difficile-Associated Diarrhea (CDAD)
Another study explored whether statins could protect against Clostridium difficile-associated diarrhea (CDAD), a common cause of nosocomial diarrhea. The study compared hospitalized patients with CDAD to those without and found that statin use was less common among CDAD patients. Multivariate analysis indicated that not using statins was associated with a higher risk of developing CDAD (OR = 2.2; 95% CI 1.82-2.73; P = .034). This implies that statins might have a protective effect against CDAD.
Statins and Clostridioides difficile Infection (CDI) Outcomes
Further supporting the potential protective role of statins, a study on veterans with Clostridioides difficile infection (CDI) found that statin users had significantly lower 30-day mortality rates compared to non-users (aOR 0.34; 95% CI 0.16–0.72). Although the recurrence of CDI within 60 days was not significantly different, the trend suggested a lower recurrence among statin users. This indicates that statins might improve clinical outcomes in patients with CDI.
Statins and Inflammatory Bowel Disease (IBD)
A systematic review and meta-analysis investigated the relationship between statin use and the risk of new-onset inflammatory bowel disease (IBD). The analysis, which included over ten million participants, suggested a non-significant trend towards a reduced risk of new-onset IBD among statin users (HR = 0.81; 95% CI, 0.63 to 1.06). While this finding is not directly related to diarrhea, it highlights the broader gastrointestinal effects of statins and their potential protective benefits.
Conclusion
Current research suggests that statins do not cause diarrhea and may even reduce its incidence. Additionally, statins appear to offer protective benefits against Clostridium difficile-associated diarrhea and improve outcomes in Clostridioides difficile infections. These findings underscore the importance of considering the gastrointestinal effects of statins in clinical practice. Further studies are warranted to fully understand the mechanisms behind these protective effects and to confirm these findings in broader populations.
