Sporotrichosis in the nasal mucosa: A single-center retrospective study of 37 cases from 1998 to 2020.

BACKGROUND: Sporotrichosis is a subcutaneous or implantation mycosis caused by some species of the genus Sporothrix. Rio de Janeiro state, Brazil, experiences hyperendemic levels of zoonotic sporotrichosis, with increasing cases of disseminated disease, especially in people living with HIV (PLHIV). Involvement of the nasal mucosa is rare and occurs isolated or in disseminated cases, with a delayed resolution. METHODOLOGY/PRINCIPAL FINDINGS: This study aimed to describe the epidemiological, clinical, and therapeutic profiles of 37 cases of sporotrichosis with involvement of the nasal mucosa treated at the ear, nose, and throat (ENT) outpatient clinic of the Instituto Nacional de Infectologia Evandro Chagas, Fundação Oswaldo Cruz, from 1998 to 2020. Data were reviewed from the medical records and stored in a database. The Mann-Whitney test was used to compare the means of quantitative variables, and Pearson chi-square and Fisher's exact tests were used to verify the association between qualitative variables (p<0.05). Most patients were males, students or retirees, with a median age of 38 years, residents in the municipality of Rio de Janeiro, and infected through zoonotic transmission. Disseminated sporotrichosis forms in patients with comorbidities (mostly PLHIV) were more common than the isolated involvement of the mucosa. The main characteristics of lesions in the nasal mucosa were the presence/elimination of crusts, involvement of various structures, mixed appearance, and severe intensity. Due to therapeutic difficulty, itraconazole was combined with amphotericin B and/or terbinafine in most cases. Of the 37 patients, 24 (64.9%) healed, with a median of 61 weeks of treatment, 9 lost follow-up, 2 were still treating and 2 died. CONCLUSIONS: Immunosuppression was determinant to the outcome, with worse prognosis and lower probability of cure. Notably in this group, the systematization of the ENT examination for early identification of lesions is recommended to optimize the treatment and outcome of the disease.

Eficácia antimicrobiana da terapia fotodinâmica no tratamento da candidíase oral em pessoas vivendo com HIV/Aids / Antimicrobial efficacy of photodynamic therapy on the treatment of oral candidiasis in people living with HIV/Aids / Eficacia antimicrobiana de la terapia fotodinámica en el tratamiento de la candidiasis bucal en personas viviendo con VIH/Sida

Objetivo: avaliar a eficácia antimicrobiana da terapia fotodinâmica no tratamento da candidíase oral em pessoas vivendo com HIV/aids. Método: estudo experimental, qualitativo e descritivo com 18 pessoas vivendo com HIV/aids que manifestavam a candidíase oral, maiores de 18 anos, que estavam em tratamento no Hospital Universitário Gaffrée e Guinle. Este grupo subdividiu-se em um grupo controle, composto por sete pessoas, que recebeu tratamento com a terapia fotodinâmica e antifúngicos, e um grupo experimental, com 11, que recebeu apenas a terapia fotodinâmica. A evolução do tratamento de cada participante foi acompanhada por registros fotográficos em duas consultas, inicial e final. Esta pesquisa foi aprovada pelo Comitê de Ética em Pesquisa do hospital, parecer número 2.431.107. Resultados: a maioria dos participantes apresentou melhora clínica, ainda que discreta, e em apenas um houve piora clínica. Conclusão: a terapia fotodinâmica antimicrobiana pode ser eficaz no tratamento da candidíase oral em pessoas vivendo com HIV/Aids

Objective: evaluate the antimicrobial efficacy of photodynamic therapy in the treatment of oral candidiasis in people living with HIV/ aids. Method: experimental, qualitative and descriptive study with 18 people living with HIV/aids who presented oral candidiasis, over 18 years of age, who were being treated at the Gaffrée and Guinle University Hospital. This group was subdivided into a control group, composed of seven people, who received treatment with photodynamic and antifungal therapy, and an experimental group, with 11, who received only the photodynamic therapy. The evolution of the treatment of each participant was followed by photographic registers in two appointments, initial and final. This research was approved by the Research Ethics Committee from the hospital, dictum number 2.431.107. Results: most of the participants showed clinical improvement, albeit discrete, and in only one there was clinical worsening. Conclusion: antimicrobial photodynamic therapy may be effective in the treatment of oral candidiasis in people living with HIV/Aids
