RESUMEN

Objectives: To determine the incidence and frequency of adverse drug reactions (ADRs) to find out factors, if any contributing to the same, while also exploring the use of amphotericin B deoxycholate as a cheaper and safe alternative to liposomal amphotericin B. Materials and Methods: It was a cross-sectional observational study, with a study population of 50 conducted over three months after ethics approval. All adult patients admitted to a tertiary care center, in a metropolitan city of Maharashtra, diagnosed with Rhino-orbito-cerebral mucormycosis, with a history of previous COVID-19 infection and receiving antifungals for the treatment of the same were included in the study. Central Drugs Standard Control Organization (CDSCO) ADR reporting forms were used to collect data. Results: Electrolyte disturbances mainly hypokalemia were the most frequently encountered ADR with both Amphotericin formulations (39/50; 20.31%) followed by pain at the injection site (33/50; 17.19%). Nephrotoxicity occurred slightly more frequently with Amphotericin B Deoxycholate (19/29; 65%), compared to Liposomal Amphotericin B (11/19; 57%), while Posaconazole was mainly associated with gastrointestinal (GI) disturbances and hepatotoxicity. Conclusion: Amphotericin B Deoxycholate was associated most with ADRs, hypokalemia, and pain at the injection site being the most frequent. However, concerning nephrotoxicity, both Amphotericin formulations showed only a modest difference. Posaconazole was associated with the least number of ADRs and had a favorable safety profile.

RESUMEN

Onychomycosis is a fungal infection of the nails that causes discoloration, thickening, and separation from the nail bed. Onychomycosis occurs in 10% of the general population, 20% of persons older than 60 years, and 50% of those older than 70 years. It is caused by a variety of organisms, but most cases are caused by dermatophytes. Accurate diagnosis involves physical and microscopic examination and culture. Histologic evaluation using periodic acid–Schiff staining increases sensitivity for detecting infection. Treatment is aimed at eradication of the causative organism and return to a normal appearance of the nail. Systemic antifungals are the most effective treatment, with meta-analyses showing mycotic cure rates of 76% for terbinafine, 63% for itraconazole with pulse dosing, 59% for itraconazole with continuous dosing, and 48% for fluconazole. Concomitant nail debridement further increases cure rates. Topical therapy with ciclopirox is less effective; it has a failure rate exceeding 60%. Several nonprescription treatments have also been evaluated. Laser and photodynamic therapies show promise based on in-vitro evaluation, but more clinical studies are needed. Despite treatment, the recurrence rate of onychomycosis is 10% to 50% as a result of reinfection or lack of mycotic cure.
