RESUMO
The emergence of non-Aspergillus mold pathogens has increased notoriously in the last decades with serious health consequences. The options of treatment for these microorganisms often resistant to a wide variety of antifungals is limited. Sertraline is an antidepressant with in vitro and in vivo antifungal properties which has been recently studied as an adjuvant in the treatment of invasive infections. In this study, we evaluated the in vitro interaction of sertraline with voriconazole and amphotericin B against Lomentospora prolificans, Scedosporium spp., Fusarium spp., Paecilomyces spp., Alternaria spp. and Curvularia spp. The minimum inhibitory concentration and minimum fungicidal concentration for sertraline were in the range of 8-32 µg/mL. Sertraline showed antifungal capacity against all fungi tested and synergism in combination with amphotericin B against some strains of Lomentospora prolificans, Scedosporium apiospermum and Alternaria alternata, antagonism with voriconazole against Purpureocillium lilacinum and indifference in both combinations for most of the other strains tested. These results suggest a potential role of sertraline as an adjuvant in the treatment of some of these serious mycoses.
