RESUMEN
OBJECTIVES: To evaluate the clinical outcomes of anidulafungin for candidemia treatment in critically ill obese patients. METHOD: A multicenter, retrospective cohort study was conducted in Saudi Arabia for critically ill adults with candidemia who received anidulafungin. Patients with obesity have a body mass index ≥ 30 kg/m2. The primary outcome was the clinical cure rate. RESULTS: 146 patients were included, 64 of whom were obese. There were no statistically significant differences in the clinical cure rate (P=0.63), microbiological cure rate (P=0.27), or the median time for a clinical cure (P=0.13) for patients with obesity compared to non-obese. The median time for a microbiological cure was longer in non-obese patients than in patients with obesity (P=0.04). The median hospital length of stay (LOS) and the median mechanical ventilation (MV) durations were numerically longer in obese patients. CONCLUSION: Clinical and microbiological cure rates and time for clinical cure were statistically similar for both groups. Considering the study's limitations (especially with a small sample size), it is uncertain if patients with obesity have similar effectiveness to non-obese patients. Future studies with larger sample sizes are warranted to evaluate if obesity negatively impacts anidulafungin's clinical outcomes for candidemia.
