Abstract:
Recent emergence of Candida auris as a multidrug resistant fungal pathogen, associated with difficult-to-control nosocomial transmission and high mortality, raises serious concerns for public health. Since it was first reported from Japan in 2009, C. auris infections have been diagnosed in several countries from all over the world. However, there is a paucity of reported cases from the Middle East. Literature search resulted in finding only six countries (Kuwait, Israel, Oman, KSA, UAE and Iran) reporting C. auris infections in the past three years. All patients were adults with several underlying comorbidities. Majority of the cases presented with bloodstream infection with crude mortality rate of 60%. All isolates were misidentified as C. haemulonii by commercial systems requiring specialized methods for identification. In vitro antifungal susceptibility testing showed 100% strains to be resistant to fluconazole (MIC 32 ≥ 256 mg/L) while variable resistance against other antifungal agents.
Insights
Multidrug-resistant Candida auris is a growing global health threat. This study highlights its limited reporting in the Middle East, where it causes severe bloodstream infections with high mortality.
Area of Science:
- Medical Mycology
- Infectious Diseases
- Public Health
Background:
- Candida auris is an emerging multidrug-resistant fungal pathogen.
- It causes difficult-to-control nosocomial infections with high mortality.
- Global spread since 2009, but limited data from the Middle East.
Purpose of the Study:
- To review reported cases of Candida auris in the Middle East.
- To analyze patient demographics, clinical presentation, and outcomes.
- To assess antifungal susceptibility patterns.
Main Methods:
- Literature search for Candida auris cases in the Middle East over the past three years.
- Analysis of reported patient data including comorbidities and infection types.
- In vitro antifungal susceptibility testing of isolates.
Main Results:
- Six Middle Eastern countries reported cases: Kuwait, Israel, Oman, KSA, UAE, and Iran.
- All reported patients were adults with comorbidities.
- Majority had bloodstream infections with a 60% crude mortality rate.
- All isolates were misidentified by commercial systems, requiring specialized identification.
- 100% of strains were resistant to fluconazole; variable resistance to other antifungals.
Conclusions:
- Candida auris poses a significant public health concern in the Middle East.
- Accurate identification and antifungal stewardship are crucial.
- Further surveillance and research are needed to combat this pathogen.
