Predictors of Recurrent Clostridioides difficile Infection

Area of Science:

• Infectious Diseases
• Microbiology
• Clinical Medicine

Background:

• Clostridioides difficile infection (CDI) recurrence affects 20-30% of patients, posing a significant clinical challenge.
• Effective risk stratification for CDI recurrence requires identifying associated factors.
• Understanding recurrence predictors is crucial for optimizing patient management strategies.

Purpose of the Study:

• To identify factors associated with recurrent Clostridioides difficile infection (CDI).
• To evaluate the predictive performance of identified factors for CDI recurrence.
• To inform improved risk stratification and management of CDI patients.

Main Methods:

• Retrospective cohort study of 100 adult patients with CDI.
• Univariable analyses, receiver operating characteristic (ROC) analysis, and logistic regression were employed.
• Evaluation of demographic, comorbidity, clinical, and laboratory parameters, alongside treatment and exposure history.

Main Results:

• Eighteen percent (18%) of patients experienced recurrent CDI.
• Independent predictors of recurrence included prior hospitalization, longer antibiotic duration, and suboptimal initial treatment response.
• Antibiotic duration demonstrated strong discriminatory performance (AUC 0.712); combined models achieved AUC 0.775.

Conclusions:

• Recurrent CDI is primarily associated with healthcare exposure and post-diagnosis treatment characteristics.
• Integrating antibiotic burden and early treatment response aids in recurrence risk assessment.
• Findings suggest focusing on treatment and exposure factors for predicting CDI recurrence.
