Objectives: We aimed to study the epidemiology, prevalence, incidence, clinical manifestations, underlying diseases, treatments, outcomes, and societal impact through disability-adjusted life years (DALYs) of IA in Iran.
Methods: A random-effect meta-analytic model was fitted to estimate the prevalence and incidence of IA in Iran. We also calculated DALYs.
Results: Out of 79 published studies during the past 25 years from Iran, 23 met the inclusion criteria. A total of 2947 patients were included, of whom 396 (13.4%) patients were diagnosed with IA according to EORTC/MSG and ICU criteria. The main underlying condition for IA was hematologic disorders (39.4%). A. flavus 86 (43%) was the most common isolate. The pooled prevalence and incidence rates were 20.5 (95% CI 12.5 to 29.9) and 4.8 (95% CI 2.3-8.2) per 100,000 population, respectively. Total DALYs was estimated 164.13 per 100,000 population. YLLs constitute the majority of IA burden compared to YLDs (162.80 YLLs/100,000 population vs 1.33 YLDs per 100,000 population). The highest YLL rates were found in people aged 45-49 (62.9 YLLs/100,000 population) and 30-34 years (45.2 YLLs/100,000 population), respectively.
Conclusion: This study indicates an increasing burden of IA in Iran, despite the extensive use of prophylaxis, challenging the public health, especially immunocompromised patients.
