RESUMO

Background: Sporotrichosis is a zoonosis caused by fungi of the Sporothrix schenckii complex. Cats have important zoonotic potential due to the high parasite load found in the cutaneous lesions. Refractory cases to antifungal therapy are increasing, becoming a public health problem. Miltefosine is a drug with high in vitro activity against Sporothrix brasiliensis. However, this efficacy has not been confirmed in vivo yet and administration has not been studied in the feline species. This study aimed to evaluate the effectiveness and safety of miltefosine administration in cats with resistant sporotrichosis.Materials, Methods & Results: Ten cats with refractory sporotrichosis were included in this study. Inclusion criteria were previous diagnosis for sporotrichosis associated with therapy with oral antifungals (itraconazole and/or potassium iodide) for more than one year, followed by one of these conditions: incomplete clinical remission, worsening of disease during treatment or recurrence after conventional treatment. Cats underwent clinical and dermatological examinations. Data on lifestyle and previous treatments were provided by the owners. Fungal culture and histochemical techniques were performed in all cats before miltefosine treatment. Blood samples were collected before and during the study for laboratory tests, such as blood count, blood urea nitrogen (BUN), serum creatinine, alanine aminotransferase (ALT) and alkaline phosphatase, as well as serology for Feline Immunodeficiency (FIV) and Feline Leukemia (FeLV). Miltefosine was prescribed at a dosage of 2 mg/kg orally every 24 h. The animals were monitored by phone during the whole process and reassessed on days 0, 15, 30 and 45 of the treatment. Out of 10 cats, lesions were present on the nose in nine, ears in four, periocular areas in one and limbs in four. One cat received treatment for 45 days, six for 30 days, one for 21 days, one for 15 days and one for 3 days.[...](AU)

RESUMO

Objetivos. Evaluar la exposición ocupacional a ciclofosfamida en nueve hospitales del Perú. Materiales y métodos. Estudio observacional de tipo transversal realizado durante el año 2010 en el cual se colectó muestras de orina de 24 h de 96 trabajadores de las unidades de mezclas oncológicas y servicios de oncología de nueve hospitales del Perú, la cuantificación de ciclofosfamida se realizó por la metodología de GC-MS ( Gas Cromathography-Mass Spectroscopy). Se realizó, además, muestreo de superficies de trabajo utilizando paños húmedos para la determinación de ciclofosfamida. Resultados. Se detectó la presencia de ciclofosfamida en orina en 67 trabajadores (concentración promedio de excreción: 74,2 ng/24 h), lo cual representa el 70% del total de la población evaluada. Basado en la excreción se puede clasificar la exposición total entre los hospitales, en términos de exposición alta (>18,9 ng/24 h), moderada (1,725 - 18,9 ng/24 h) y baja (<1,725 ng/24 h), con una frecuencia porcentual de 31,3; 26,0 y 42,7% respectivamente. Además, como parte de la evaluación ambiental, se encontró concentraciones de ciclofosfamida de 14,72, 14,98 y 5,12 ng/cm².Conclusiones. Se evidencia una contaminación por ciclofosfamida en las áreas donde se realizan los preparados oncológicos y la presencia de ciclofosfamida en muestras de orina de trabajadores expuestos a citostáticos.


Objetives. Evaluate occupational exposure to cyclophosphamide in nine hospitals of Peru. Materials and methods. Cross-cutting observational study conducted in 2010, for which 24-hour urine samples were obtained from 96 employees of the oncologic mixture units and oncology services of nine hospitals in Peru, the quantification of cyclophosphamide was done through the GC-MS methodology ( Gas Cromathography-Mass Spectroscopy). Additionally, working surfaces were tested by obtaining samples with wet wipes for identification of cyclophosphamide. Results. Cyclophosphamide was detected in urine samples in 67 employees (average concentration of excretion: 74.2 ng/24 h), accounting for 70% of the total population to be assessed. Based on the excretion, total exposure among hospitals can be classified as high level (>18.9 ng/24 h), moderate level (1,725 - 18.9 ng/24 h) and low level (<1,725 ng/24 h), with a percent incidence of 31.3; 26.0 and 42.7% respectively. Additionally, as part of the environmental evaluation, concentrations of cyclosphamide were found in 14.72, 14.98 and 5,12 ng/cm2. Conclusions. Contamination through cyclophosphamide in areas where oncological preparations are done and the presence of cyclophosphamide in urine samples of workers exposed to cytostatics substance were observed.
