Clinical profile and outcome of COVID-19 associated mucormycosis in Shiraz, South Iran: a longitudinal study
Abstract
Background and Objectives: Numerous cases of mucormycosis appeared among COVID-19 patients, predominant- ly in Asian countries. This study aimed to investigate the clinical profile, in-hospital outcome, and one-year prognosis of COVID-19-associated mucormycosis (CAM).
Materials and Methods: All patients who developed CAM in Shiraz, South Iran, between July and October 2021 were included in this study. We collected data on presentations, comorbidities, risk factors, and outcomes.
Results: Sixty-two patients with CAM were analyzed; the mean age was 59.3 years, and 58.1% were male. Diabetes mel- litus was present in 80.6% (11.2% uncontrolled), hypertension in 54.8%, and chronic kidney disease in 11.3%. All patients had sinonasal involvement; ophthalmic, cutaneous, cerebral, gastrointestinal, pulmonary, and renal involvement occurred in 41.9%, 8.1%, 6.4%, 6.4%, 1.6%, and 1.6%, respectively. In-hospital and one-year mortality were 40.3% and 48.3%. Concur- rent CAM and COVID-19, hypertension, older age, and radiologically severe COVID-19 lung involvement were associated with higher mortality. In multivariable analysis, age ≥60 years predicted in-hospital (OR: 5.47; 95% CI: 1.53-19.56) and one-year mortality (OR: 7.65; 95% CI: 1.90-30.84). Long-term mortality was also associated with ≥3 risk factors (OR: 4.12; 95% CI: 1.09-15.52) and lung severity index >30 (OR: 9.35; 95% CI: 1.01-86.63).
Conclusion: These findings emphasize the critical role of age in immune responses to opportunistic infections and highlight the impact of multiple comorbidities and severe lung damage on long-term prognosis in CAM.
