BackgroundSporotrichosis is a subacute and chronic infection caused by Sporothrix schenckii, which affects humans and other mammals. Clinical and epidemiological information in Colombia is scarce.ObjectiveTo describe clinical and socio-demographic findings and diagnostic tests in patients with sporotrichosis from 1996 to 2005 in a national reference center in Colombia, and to determine the institutional prevalence from 2002 to 2005.Material and methodsThis was a prevalence study, including patients with clinical diagnosis of sporotrichosis and at least one of the following criteria: positive culture with S. schenckii, pathologic diagnosis suggestive of sporotrichosis, or response to treatment with potassium iodide.ResultsSixty cases were included, 67% were male, and 25% of them were farmers. The most affected anatomical areas were the forearms and hands (32.5% and 22.8% respectively). Most cases came from the Cundinamarca and Boyacá areas. The cases presented as fixed cutaneous sporotrichosis and lymphangitic sporotrichosis. Differential diagnoses with: leishmaniasis and chromoblastomycosis were performed in most of the cases. All patients were treated with potassium iodide. The prevalence for our center from 2002 to 2005 was 8 cases per 100,000 patients.ConclusionsThe characteristics of our patients are similar to those described in other populations, with some differences. The culture continues to be the gold standard for diagnosis purposes. Potassium iodide is the treatment of choice in our center.  相似文献

Sporotrichosis is rare in Turkey. We report a 40-year-old woman who had subcutaneous sporotrichosis caused by sporothrix schenckii that was successfully treated with terbinafine (250 mg, twice a day) for a period of 6 months. She received a saturated solution of potassium iodide orally for two months. Terbinafine and potassium iodide are suggested to be the agents of choice for treatment of subcutaneous sporotrichosis.  相似文献

An endemic area of sporotrichosis is described in the Lake of Ayarza District, South Guatemala, where 53 patients have been observed within 3 years. In 45.3% of the cases, the infection appeared after handling fish. The disease was more frequently observed in man (83%) and in patients less than 30 years of age. The most frequent clinical type was the ascending lymphocutaneous sporotrichosis of the limbs. Some cases of ulcerative or verrucous lesions were seen. Almost all the patients cured rapidly either by potassium iodide (46 patients) or spontaneously, or after application of local heat (4 patients). Intradermal tests were performed in healthy population in the endemic area and, for comparison, in Guatemala City. Whole yeast cell antigens of Sporothrix schenckii and Ceratocystis stenoceras were used in these tests. Skin tests to both antigens were more frequently positive in the endemic area; the highest frequency was obtained with the antigen of C. stenoceras. A serological study was performed in 26 patients. The fluorescent antibody staining technique was more sensitive than yeast cell and latex particles agglutinations. C. stenoceras was isolated from bark of some trees, especially Eucalyptus, in the environment, but not S. schenckii.  相似文献

Sporotrichosis occurs worldwide, and the metropolitan region of Rio de Janeiro, Brazil, is a main endemic area, with a large number of human and animal cases in the last 19 years. This mycosis is more frequently described in cats rather than in dogs. There are a limited number of oral antifungal agents for the treatment of sporotrichosis in animals. In this context, the effectiveness of terbinafine in the treatment of sporotrichosis in humans, as well as the promising results of in vitro susceptibility tests, inspired us to use this drug in the therapy of this mycosis in dogs. We reported for the first time the use of terbinafine in the treatment of two dogs with sporotrichosis caused by Sporothrix brasiliensis. Moreover, we provided an overview of therapeutic features of canine sporotrichosis cases reported since the 1960s. One of the dogs presented the fixed cutaneous form of the disease, while the other patient presented hyperemia of the nasal mucosa and respiratory signs only. Terbinafine showed high antifungal activity in vitro against the canine Sporothrix isolates. The dogs were successfully treated with terbinafine, with remission of all clinical signs initially presented. The current reports indicate that this drug can emerge as a therapeutic option for canine sporotrichosis.  相似文献

Studies on mode of action of potassium iodide upon Sporotrichosis   总被引:2,自引:0,他引:2  
Reigo Wada 《Mycopathologia》1968,34(2):97-107
Conclusion Growth inhibition ofSporotrichum schenckii was observed when potassium iodide or iodine-potassium iodide were added to Sabouraud's medium. The inhibition occurred also after the fungus was brought into contact with the compounds before inoculation. Iodine-potassium iodide was more effective on the inhibition than potassium iodide. The presence of I131 in association with the organism was demonstrated. The results suggest that the effect of iodine compounds on sporotrichosis is due to a direct fungicidal action of iodine.  相似文献

BackgroundSporotrichosis is a worldwide subcutaneous mycosis caused by Sporothrix spp. In the past, this infection was associated with armadillo hunting, horticulturists, miners, and gardeners, being considered an implantation mycosis acquired by plant debris injury. Nevertheless, since the late nineties, it has been considered a zoonotic disease in Brazil. Here we report a case series of 121 patients with cat-transmitted sporotrichosis seen in Northeast Brazil.Methodology/Principal findingsPatient’s demographic, clinical data, and length of treatment were recorded. In addition, a mycological examination and further PCR confirmation of species identification were performed. One hundred and twenty two patients were diagnosed with subcutaneous sporotrichosis from October 2016 to December 2019, while PCR revealed that 71 of them were due to S. brasiliensis. The majority of the individuals were female (n = 86; 70.5%). Patient’s age ranged from 5 to 87 years old. The clinical forms found were lymphocutaneous (58.2%) and fixed cutaneous (39.4%). Interestingly, 115 patients reported previous contact with cats diagnosed with sporotrichosis. Patients were successfully treated with itraconazole and potassium iodide.Conclusions/SignificanceOur study adds important contributions for the investigation of the spread of cat-transmitted subcutaneous sporotrichosis in Brazil, specifically towards the Northeast region of a continental-size country. It will also help clinicians to be aware of the existence and importance to accurately diagnose sporotrichosis and treat patients with this infectious disease in the lowest income region of Brazil.  相似文献

A ten year old boy developed lymphocutaneous sporotrichosis following a wild rodent bite. The infection was successfully treated with potassium iodide. Sporotrichosis in humans has followed bites, pecks and stings inflicted by a variety of animals, birds and insects. Many species of animals are susceptible to infection by Sporothrix schenkii, but transmission from infected animals to man is uncommon.  相似文献

BackgroundThe gold standard for the sporotrichosis diagnosis is culture; however, serologic approaches have been recently implemented to aid in the sporotrichosis diagnosis. Nevertheless, the clinical consequences of the introduction of serologic tests are poorly addressed.AimsTo correlate the results of culture and serology of patients with suspected sporotrichosis.MethodsA retrospective study of 198 patients with suspected sporotrichosis was conducted. Information about culture isolation of Sporothrix from clinical samples and antibody detection by an enzyme-linked immunosorbent assay (ELISA) were obtained from the medical records of the patients.ResultsPositive culture and antibody detection was observed in the samples of 84 patients (42.4%). Forty-one samples (20.7%) showed negative results with both techniques and divergent results were obtained in the samples of 73 patients (36.9%). False negative results in the ELISA were observed with 23 patients (31.5%), 78.3% of them with less than 30 days of infection (p = 0.0045). Among the initial false positive ELISA in the sera of 50 patients, four samples in culture yielded the growth of Sporothrix, and 27 improved with itraconazole. At the end of follow-up, a diagnosis of proven or probable sporotrichosis was established in 139 patients, and possible sporotrichosis in 11 patients. The treatment of the patients with probable sporotrichosis with antifungal drugs resulted in clinical cure for these individuals.ConclusionsThese two techniques are complementary in the diagnosis of sporotrichosis, making diagnosis and clinical decision more precise.  相似文献
