Abstract Background: The increase in the zoonotic epidemic of sporotrichosis caused by Sporothrix brasiliensis, which started in the late 1990s in Rio de Janeiro and is now found in almost all Brazilian states, has been equally advancing in neighboring countries of Brazil. Changes in the clinical-epidemiological profile, advances in the laboratory diagnosis of the disease, and therapeutic difficulties have been observed throughout these almost 25 years of the epidemic, although there is no national consensus. The last international guideline dates from 2007. Objectives: Update the clinical classification, diagnostic methods and recommendations on the therapeutic management of patients with sporotrichosis. Methods: Twelve experts in human sporotrichosis were selected from different Brazilian regions, and divided into three work groups: clinical, diagnosis and treatment. The bibliographic research was carried out on the EBSCOHost platform. Meetings took place via electronic mail and remote/face-to-face and hybrid settings, resulting in a questionnaire which pointed out 13 divergences, resolved based on the opinion of the majority of the participants. Results: The clinical classification and laboratory diagnosis were updated. Therapeutic recommendations were made for the different clinical forms. Conclusions: Publication of the first national recommendation, carried out by the Brazilian Society of Dermatology, aimed at the Brazilian scientific community, especially dermatologists, infectologists, pediatricians, family medicine personnel, and laboratory professionals who work in the management of human sporotrichosis.

BACKGROUND Sporothrix brasiliensis is the causative agent of zoonotic cases of sporotrichosis in Brazil and is associated with atypical and severe presentations in cats, dogs, and humans. Sporotrichosis treatment is usually time- and cost-consuming, sometimes with poor response and host toxicity. Schinus terebinthifolius has proven efficacy against bacteria and fungi of clinical interest. OBJECTIVE To determine the in vitro activity of S. terebinthifolius against S. brasiliensis. METHODS Five S. brasiliensis isolates and three reference strains were subjected to a hydroethanol extract derived from the leaves of S. terebinthifolius and its fractions. The minimal inhibitory concentration (MIC) was determined using the broth microdilution method according to the M38-A2 CLSI guidelines. Also, the fungicidal/fungistatic activity of the extract and fractions was studied. FINDINGS The crude extract of S. terebinthifolius inhibited the growth of S. brasiliensis (MIC: 0.5-1.0 µg/mL), while the partitioned extracts dichloromethane, ethyl acetate, and butanol demonstrated growth inhibition at 8 µg/mL due to a fungistatic activity. MAIN CONCLUSIONS Due to its in vitro efficacy against S. brasiliensis and its known pharmacological safety, S. terebinthifolius is a candidate to be tested using in vivo models of sporotrichosis.

BACKGROUND Sporotrichosis is a subcutaneous mycosis caused by dimorphic pathogenic fungi belonging to the Sporothrix genus. Pathogenic Sporothrix species typically produce melanin, which is known to be a virulence factor. OBJECTIVES The aim of this study was to perform phenotypic, genotypic, and virulence analyses of two distinct Sporothrix brasiliensis strains isolated from the same lesion on a patient from Rio de Janeiro. METHODS AND FINDINGS Genotypic analyses by partial sequencing of the calmodulin, β-tubulin, and chitin synthase genes, as well as polymerase chain reaction (PCR)-fingerprinting by T3B, M13, and GACA, showed that the isolates were very similar but not identical. Both isolates had similar phenotypic characteristics and effectively produced melanin in their yeast forms, accounting for their ability of causing disease in a murine sporotrichosis model. Remarkably, isolate B was albino in its environmental form but caused more severe disease than the pigmented A isolate. CONCLUSIONS These findings indicate that the patient was infected by two genetically and biologically distinct S. brasiliensis that vary in their production of melanin in their environmental forms. The results underscore the importance of characterizing phenotypically different isolates found in the same clinical specimen or patient.

Resumo: A esporotricose é uma micose subcutânea de distribuição global e, em geral, os pacientes são tratados ambulatorialmente. Desde 1998, observa-se aumento dos casos no Estado do Rio de Janeiro, Brasil, especialmente por transmissão zoonótica envolvendo gatos. Os pacientes coinfectados pelo vírus da imunodeficiência humana (HIV), muitas vezes, necessitam de hospitalizações e evoluem a óbito. Este estudo analisa e descreve dados de 1992 a 2015, provenientes de bancos de dados do Sistema Único de Saúde. No Brasil, ocorreram 782 hospitalizações e 65 óbitos. Em 6% das hospitalizações e 40% dos óbitos, havia coinfecção pelo HIV. No Rio de Janeiro, foram 250 hospitalizações e 36 óbitos, com aumento progressivo, ao longo do período. Destacaram-se, ainda, São Paulo e Goiás. Homens, não brancos, com baixa escolaridade evoluíram mais frequentemente a óbito. Conclui-se que a esporotricose está associada a hospitalizações e óbitos em todo o Brasil, com destaque para o Rio de Janeiro.

Abstract: Sporotrichosis is a subcutaneous mycosis with global distribution, and patients generally receive outpatient treatment. Since 1998 there has been an increase in cases in the state of Rio de Janeiro, Brazil, mainly via zoonotic transmission involving cats. Patients coinfected with the human immunodeficiency virus (HIV) often require hospitalization and evolve to death. This study analyzes and describes data from 1992 to 2015 obtained from the database of the Brazilian Unified National Health System (SUS). There were 782 hospitalizations and 65 deaths in Brazil. Six percent of the hospitalizations and 40% of the deaths involved coinfection with HIV. There were 250 hospitalizations and 36 deaths in Rio de Janeiro, with a progressive increase over the course of the period. The states of São Paulo and Goiás also showed high numbers. Men, non-whites, and individuals with low schooling evolved more frequently to death. In conclusion, sporotrichosis is associated with hospitalizations and deaths throughout Brazil, especially in the state of Rio de Janeiro.

BACKGROUND Cutaneous tuberculosis (CTB) is a rare extrapulmonary form of tuberculosis (TB). Despite the increase in the number of cases of TB and HIV, few cases of CTB have been reported. OBJECTIVE To describe CTB cases among patients with HIV infection from a cohort with tuberculosis. METHODS We describe a series of 15 CTB and HIV cases, based on secondary data from 2000 to 2016. Diagnosis was based on isolation of Mycobacterium tuberculosis in culture or clinical response to anti-tuberculous treatment associated with positive smear or histopathologic findings from affected skin or an adjacent lymph node. FINDINGS Scrofuloderma was present in 12 (80%) patients and solitary gumma in three (20%) patients. One case of scrofuloderma was associated with papulonecrotic tuberculid. Seven (46.6%) patients had pulmonary TB. Diagnosis was based on culture in nine patients (60%). The median CD4 cell count was 262 cells/µL. All patients were cured at the end of treatment (median time 6 months). Three patients presented with immune reconstitution inflammatory syndrome. CONCLUSIONS In this study, CTB associated with HIV infection presented as localised forms or in association with pulmonary TB. In patients with HIV who have subacute and chronic skin lesions, CTB should be considered in differential diagnosis, which may represent a good opportunity for early diagnosis of active TB.

Sporotrichosis associated with exposure to domestic cats is hyperendemic in Rio de Janeiro, Brazil. A review of the clinical records at our institute revealed four patients with clinical signs of dacryocystitis and a positive conjunctival culture for Sporothrix who were diagnosed with Sporothrix dacryocystitis. Three patients were children (< 13 years of age) and one patient was an adult. Two patients reported contact with a cat that had sporotrichosis. Dacryocystitis was associated with nodular, ulcerated lesions on the face of one patient and with granulomatous conjunctivitis in two patients; however, this condition manifested as an isolated disease in another patient. All of the patients were cured of the fungal infections, but three patients had chronic dacryocystitis and one patient developed a cutaneous fistula. Sporotrichosis is usually a benign disease, but may cause severe complications when the eye and the adnexa are affected. Physicians, especially ophthalmologists in endemic areas, should be aware of the ophthalmological manifestations and complications of sporotrichosis.
