ARTICLE HIGHLIGHTS
Research background

The coronavirus disease 2019 (COVID-19) pandemic profoundly altered medical practice and has brought forth multiple challenges for gastroenterologists in handling of patients with digestive diseases, due to the many digestive and hepatic manifestations of COVID-19. Frequently, residual/post-infection issues can alter the course of patients with digestive disorders (especially patients with inflammatory bowel disease, advanced liver disease, etc.). Clostridium difficile infection (CDI) was also a challenge for gastroenterology during the COVID-19 pandemic.

Research motivation

Many patients diagnosed with COVID-19 have numerous risk factors for CDI, including broad-spectrum antibiotic treatment, hospitalization, elderly age, multiple comorbidities, and immunocompromised status.

Research objectives

The aim of this study was to analyze the factors that influenced CDI development after COVID-19.

Research methods

Between March 2020 to December 2020, we performed a prospective observational study including 447 patients diagnosed with CDI who had been admitted to our tertiary referral university hospital. The diagnosis of CDI was based on the presence of diarrhea (≥ 3 watery stools within 24 h) associated with C. difficile toxin A or B.

Research results

Most of the patients in our study were male (54.3%), and showed a mean age of 59.7 ± 10.8 years. Of all the patients included in the study, 76 (17.0%) had a history of COVID-19. The patients with a history of COVID-19 were more likely to be elderly, have a history of alcohol consumption and have previous hospitalizations and antibiotic treatments than the patients without a history of COVID-19. The patients with a history of COVID-19 also needed higher doses of vancomycin and were prone to recurrent disease. Age over 60 years, residence in an urban area, previous antibiotic treatment, and previous and current alcohol consumption were identified as risk factors for CDI development in patients with COVID-19.

Research conclusions

Hospitalizations, antibiotic use and alcohol consumption represent risk factors for CDI development in patients over 60-years-old from an urban area with a history of COVID-19. These patients were at higher risk of recurrence and needed higher doses of vancomycin for CDI treatment.

Research perspectives

Our study highlights the importance of judicious use of antibiotics and recognizing the patients at risk for developing CDI. Future research should focus on the management of patients with CDI after or during COVID-19 in order to improve the prognosis in these patients.
