Treatment of human cutaneous sporotrichosis with itraconazole.

Eighteen adult white male patients with cutaneous sporotrichosis were treated with itraconazole following different daily dose schemes. Cure was obtained in all cases after periods of 15-75 days (median 44 days) with total doses between 3.1 and 14.8 g (median 8.4 g). No serious side effects were observed and no relapses occurred in the follow-up period of between 1 and 26 months (median 14.7). These results show that itraconazole represents a safe and effective drug for the treatment of sporotrichosis. Comparison with other studies leads us to consider a daily dose of 200 mg as the most appropriate. A concomitant warming of the affected limbs should be recommended.

Cutaneous sporotrichosis in the period 1978-1992 in the province of Bari, Apulia, Southern Italy.

The authors report 16 cases of cutaneous sporotrichosis observed in the province of Bari, southern Italy, since 1978. While no more than 55 cases have been documented in other European countries in the last 30 years, in Italy 58 cases (present series included) have been recorded in the same time period. Furthermore, 42 of them (73.7%) originated from Apulia. This unexpectedly high incidence rate in Italy, and in Apulia in particular, provides evidence of the important role played by this area in the ecoepidemiology of sporotrichosis in Europe.

A case of sporotrichosis treated successfully with oral fluconazole 200 mg once weekly.

A case of fixed cutaneous sporotrichosis that developed on the extensor aspect of the left wrist of an 83-year-old woman was treated once a week with 200 mg of oral fluconazole. This dermatological lesion healed within 4 months, leaving a scar. No side-effects were seen. At the time of writing, 7 months after the end of treatment, there has been no recurrence. Reports on the efficacy of once-weekly fluconazole administration in cases of sporotrichosis have appeared, but it would be valuable to study more such cases.

Haematogenous spread of Sporothrix schenckii in cats with naturally acquired sporotrichosis.

The recovery of Sporothrix schenckii from blood samples is rare, and the diagnosis of systemic sporotrichosis is usually made at necropsy. In this report, S schenckii was isolated from two or more internal organs of nine necropsied cats with naturally acquired sporotrichosis. Haematogenous spread was demonstrated in vivo by the isolation of S schenckii from the peripheral blood of 17 (n = 49, 34.4 per cent) cats. Feline leukaemia virus (FeLV) was not detected, and co-infection with feline immunodeficiency virus (FIV), observed in nine cases (n = 43, 20.9 per cent), apparently did not affect the isolation of S schenckii from peripheral blood or from the internal organs.

Sporotrichosis in the metropolitan area of Cusco, Peru, and in its region.

Eight cases of sporotrichosis originating from the metropolitan area of Cusco, Peru, and its region are described, including the circumstances of infection and the isolation of Sporothrix schenckii from the lesions. This finding classifies this particular area with high altitude, low temperature and dry weather as an endemic zone of interest in the epidemiological and ecological study of Andean sporotrichosis. Among the eight cases observed, five were of the fixed cutaneous type and three were lymphocutaneous. Six patients were male and two female. Two paediatric cases were also observed. Therapy with potassium iodide was very satisfactory, whereas poor results were obtained with ketoconazole.

Experimental therapy of cladosporiosis and sporotrichosis with 5-fluorocytosine.

Cladosporium trichoides and Sporothrix schenckii are fungi known to be pathogenic for man. No effective chemotherapy is available for cladosporiosis, and systemic sporotrichosis can be very resistant to antifungal chemotherapy. Experimental infections of mice with these fungi resembled their respective infections in man and provided a model for evaluating a new antifungal agent, 5-fluorocytosine (5-FC). Our results with four isolates of C. trichoides demonstrated a statistically significant dose-related therapeutic effect with 5-FC. Mortality was significantly reduced in all treatment groups, and survivors showed no clinical sign of disease despite positive brain cultures. Results with a single isolate of S. schenckii were less encouraging. Fatality rate was significantly decreased in all treatment groups, but no trend was noted with increasing 5-FC dosage. Survivors manifested the signs of active disease, and all liver and spleen cultures were positive for S. schenckii. These results indicated that (i) 5-FC may be the first drug useful in the treatment of cladosporiosis, and (ii) 5-FC may have only limited therapeutic benefit in systemic sporotrichosis.

Susceptibility of congenitally athymic (nude) mice to sporotrichosis.

Congenitally athymic (nu/nu) mice were found to be more susceptible to intravenous challenge with Sporothrix schenckii than their phenotypically normal (nu/+) littermates as measured by lethality and the number of viable yeast cells in the liver 7 days postinfection. Thymus reconstitution of nu/nu mice (nu/thy) conferred a significant degree of resistance to sporotrichosis. Immunization greatly enhanced the resistance of nu/thy and nu/+ mice, but unexpectedly increased the susceptibility of nu/nu mice. The susceptibility of nonimmunized nu/nu mice and the finding that thymus transplants augmented resistance to sporotrichosis suggest that T lymphocytes are critical to host defense.

Sporothrix schenckii fungemia without disseminated sporotrichosis.

Fungemia is a rare complication of Sporothrix schenckii infection and has always been associated with disseminated sporotrichosis. We describe an immunocompetent patient with localized lymphocutaneous sporotrichosis from whose blood the fungus was isolated. A lysis-centrifugation blood culture system may have improved our ability to detect low-level S. schenckii fungemia.

Comparison between histochemical and immunohistochemical methods for diagnosis of sporotrichosis.

AIMS: To compare the efficacy of histochemical and immunohistochemical methods in detecting forms of Sporothrix schenckii in tissue. METHODS: Thirty five cutaneous biopsy specimens from 27 patients with sporotrichosis were stained by histochemical haematoxylin and eosin, periodic acid Schiff, and Gomori's methenamine silver methods and an immunohistochemical (avidin-biotin complex immunoperoxidase) (ABC) technique associated with a newly produced rabbit polyclonal antibody anti-Sporothrix schenckii. RESULTS: A total of 29 (83%) cases were positive by the ABC method used in association with anti-Sporothrix schenckii rabbit polyclonal antibodies. Histochemical methods, using silver staining, periodic acid Schiff, and conventional haematoxylin and eosin detected 37%, 23%, and 23% of forms of S schenckii, respectively. The ABC technique was significantly more reliable than periodic acid Schiff and silver staining techniques. CONCLUSIONS: It is concluded that immunostaining is an easy and rapid method which can efficiently increase the accuracy of the diagnosis of sporotrichosis in human tissue.

Primary pulmonary sporotrichosis with unusual fungal morphology.

Primary pulmonary sporotrichosis is a rare disease. Comstock and Wolson (1975) were able to trace approximately 30 such cases. We report a further case; to our knowledge, the various stages in the development of sporotrichosis, from a cigar body to the mature asteroid body with radiations which were present in our case, have not been so well demonstrated in a single case.

Primary pulmonary sporotrichosis.

A case of pulmonary sporotrichosis is described with secondary involvement of the rectum which was misdiagnosed as tuberculosis for a number of years. The authors suggest that every nondiagnosed chronic cavitary disease in the lung should include appropriate tests for sporotrichosis.

Survey of 200 cases of sporotrichosis.

A survey of 200 cases of sporotrichosis seen at the Dermatology Clinic of Chiba University Hospital from May 1965 to August 1983 is reported. The proportion of cases with sporotrichosis to the total number of outpatients was 0.15%. A higher percentage of cases fell into the less than 12-year-old or more than 40-year-old age groups. The male to female ratio was 1:2. Half of the cases occurred in farmers. Seventy-eight cases had a history of injury. One hundred and eight cases showed the cutaneous lymphangitic type and 92 cases showed the localized cutaneous type. The face and upper extremities were the most frequently affected sites. The sporotrichin skin test was positive in 96.3% of the cases. The causative organism was demonstrated in tissue sections in 94.5% of the cases.

Primary pulmonary sporotrichosis complicated by perirectal abscess.

A 48-year old, retired mounted policeman was followed for 4 years through 4 hospitalizations for progression of his bilateral, cavitary lung disease. His sputum was always negative for acid-fast bacilli and fungi. Subsequently, a painful perianal swelling appeared that was incised and drained of purulent material. Five years after first seen, sputum and rectal drainage revealed Sporothrichum schenckii in many cultures. Serologic evidence of sporotrichosis was also present. With amphotericin B therapy, the patient showed marked clinical improvement. Unfortunately, he died from an episode of acute respiratory failure. Although most patients with primary cutaneous or primary pulmonary sporotrichosis are horticulturists, the writers believe that this disease should be considered in any undiagnosed, chronic, cavitary lung disease, even in the absence of this occupational history.

Primary pulmonary sporotrichosis.

A 34-year-old alcoholic and drug addict developed cavitary pulmonary sporotrichosis that progressed slowly during 6 years. Pulmonary resection and pre- and postoperative therapy with amphotericin B were associated with prompt clinical improvement with no evidence of relapse during a 2-year follow-up. Histologic examination of lung revealed granulomatous inflammation with organisms consistent with Sporothrix schenckii, and interstitial talc (magnesium silicate) granulomas. The latter finding was consistent with the history of intravenous drug abuse. Although the presence of silicates in lung enhances the pathogenicity of some microorganisms, the relation of these findings to the pathogenesis of sporotrichosis in our patient is unclear.

Pulmonary and articular sporotrichosis.

A 46-year-old man presented with swelling and pain in the right knee and a history of nonproductive cough and weight loss. Sporotrichum schenkii was cultured from synovium, synovial fluid, sputum, and bronchial washings. No other pathogens were cultured. Neither skin lesions nor history of exposure to S. schenckii was present, but 7 years before this admission the patient had been treated for suspected pulmonary tuberculosis despite negative mycobacteriology. The case is believed to represent systemic spread from chronic pulmonary sporotrichosis and supports the hypothesis that the lung may serve as a portal of entry in noncutaneous systemic sporotrichosis.

A case of feline sporotrichosis.

We excised surgically a feline granulomatous lesion and performed histopathological, mycological and molecular examinations. As a result, it was diagnosed as sporotrichosis, which was the second recorded case of a cat so afflicted in Japan. After the operation, we recognized another nodule on the lymph node. Histopathological examination was therefore performed, but no fungi were detected. To prevent recurrence, the cat was administered a antimycotic drug, itraconazole. As a result, no recurrence was found. Excision of the lesion is the treatment of choice for feline sporotrichosis.

Pulmonary sporotrichosis treated with itraconazole.

A 62-year-old woman had chronic cavitary pulmonary sporotrichosis refractory to medical management over an 8-year period. She was treated with oral itraconazole and had an apparent microbiologic and clinical response; however, the patient succumbed to progressive pulmonary hypertension. The early use of oral itraconazole for treatment of pulmonary sporotrichosis is advocated.
