Intranasal clotrimazole spray 1% associated with oral itraconazole for nasal feline sporotrichosis: a case series.

Rev Bras Med Vet 2022 26;44:e004821. Epub 2022 May 26.

Veterinarian, DSc. DMCV, IV, UFRRJ. Seropédica, RJ, Brazil.

Feline sporotrichosis is a major clinical problem among cats in Brazil and is also a neglected, but important, public health issue, due to its zoonotic potential. The nasal clinical form of the disease is particularly challenging, having treatment refractoriness and clinical signs relapse as common features. This case series study aimed to preliminarily describe the effects of the azolic antifungal drug, clotrimazole, as a topical 1% solution spray, together with itraconazole on inducing disease remission, as well as treatment tolerability and safety.

Beyond Domestic Cats: Environmental Detection of DNA in a Hyperendemic Area of Sporotrichosis in Rio de Janeiro State, Brazil.

J Fungi (Basel) 2022 Jun 4;8(6). Epub 2022 Jun 4.

Laboratório de Micologia, Instituto Nacional de Infectologia Evandro Chagas, Fundação Oswaldo Cruz, Rio de Janeiro 21040-900, Brazil.

In Brazil, sporotrichosis has transitioned from a rural to urban disease, driven by a shift in the initiation of infection from the accidental inoculation of organic matter to the traumatic implantation of the fungus by cats. Since the emergence of zoonotic sporotrichosis caused by , investigations have largely ignored the environmental habitat of the pathogen due to its association with domestic cats. Therefore, we investigated 18 environmental samples collected from rural areas of two cities where zoonotic sporotrichosis is endemic, but where domestic cats are scarce. Read More

Drug Discovery and Development Division, Patanjali Research Institute, Haridwar, India.

Chronic topical cases of Sporotrichosis, a chronic fungal infection caused by the ubiquitously present cryptic members of the Sporothrix species complex, are treated with oral administrations of itraconazole. However, severe pulmonary or disseminated cases require repeated intra-venous doses of amphotericin B or even surgical debridement of the infected tissue. The unavoidable adverse side-effects of the current treatments, besides the growing drug resistance among Sporothrix genus, demands exploration of alternative therapeutic options. Read More

Household outbreak of sporotrichosis: towards the One Health approach.

Rev Soc Bras Med Trop 2022 6;55:e0021. Epub 2022 Jun 6.

Universidade Federal de Minas Gerais, Departamento de Medicina Veterinária Preventiva, Belo Horizonte, MG, Brasil.

Although sporotrichosis requires a broad approach for control, few reports have described the relationship between the index case and secondary contacts. In the present work, we report an outbreak involving a woman, a dog, and two cats from the same household environment, including the clinical and epidemiological aspects and outcomes, and discuss the importance of a One Health approach to face this neglected disease. The joint efforts of professionals such as veterinarians and physicians are essential for early diagnosis and surveillance, which contributes to the rapid identification and control of zoonotic sporotrichosis outbreaks.

Identifying novel drugs with new modes of action for neglected tropical fungal skin diseases (fungal skinNTDs) using an Open Source Drug discovery approach.

Expert Opin Drug Discov 2022 Jun 9:1-19. Epub 2022 Jun 9.

Department of Microbiology and Infectious Diseases, Erasmus MC, University Medical Center Rotterdam, Rotterdam, The Netherlands.

Introduction: The three fungal skin neglected tropical diseases (NTD) - mycetoma, chromoblastomycosis and sporotrichosis - currently lack prioritization and support to establish drug discovery programs in search for novel treatment options. This has made the efforts to identify novel drugs for these fragmented skinNTDs.

Areas Covered: To help escalate the discovery of novel drugs to treat these fungal skinNTDs, the authors have prepared an overview of the compounds with activity against fungal skinNTDs by analyzing data from individual drug discovery studies, including those performed on the Medicines for Malaria Venture (MMV) open access boxes.

Centre d'Infectiologie Charles Mérieux, Université d'Antananarivo, Antananarivo 101, Madagascar.

Chromoblastomycosis and sporotrichosis are the two main implantation mycoses that are now recognized as fungal neglected tropical diseases (NTDs). Their laboratory diagnosis mainly relies on direct microscopy, histopathology, and identification of the fungus by culture. However, to be appropriately used, these techniques require mycological expertise that is not widely available and may be absent in peripheral health care facilities in endemic areas. Read More

Department of Dermatology, The First Hospital of China Medical University, Shenyang, China.

Macrophages, which serve as a bridge between innate and adaptive immunity, play an important role in sporotrichosis. Sporothrix schenckii infections can produce immune responses such as macrophage polarization and inflammatory factor secretion. In the early stages of inflammation, the expression of DAB2 in macrophages is increased, which controls the secretion of inflammatory factors and affects the polarization of macrophages. Read More
