Abstract

Purpose of Review

Cystic fibrosis (CF) is an inherited disease that can progressively affect multiple organs including respiratory tract. CF has been believed to occur infrequently in the Middle East (ME). However, it seems that CF maybe more common in ME countries than expected before. Despite the fact that surveillance of fungal infections is essential, data in the ME region remain scarce. This narrative review aims to evaluate the previously published data on the prevalence of fungal respiratory colonization and infections, spectrum of isolated fungi from the respiratory tract, and antifungal treatment in CF patients across ME countries.

Recent Findings

Among different opportunistic fungal pathogens, Aspergillus fumigatus and Candida species were reported as the most prevalent mold and yeast like fungi isolated from respiratory tract of CF patients from ME countries. A. fumigatus was reported as the common filamentous colonizing fungi of the respiratory tract of CF patients from Turkey in the range 10.4–76.3%. Colonization due to Aspergillus also showed the highest frequency for A. fumigatus (50.0%) in CF patients from Qatar. However, in a more comprehensive study from Iran, A. flavus was the most common. Scedosporium spp. has not been reported in CF patients from ME countries except for one study in Iran.

Summary

Future efforts should focus on improving laboratory capacities in ME for detection of common and rare fungal pathogens. National CF registries could help to collect more systematic data on fungal colonization and infection in patients in the ME.
