Histoplasmosis is a fungal disease, endemic in South America, and seldom reported in paediatrics.
To report the epidemiology, clinical features and outcome of children diagnosed with histoplasmosis in an Argentinian Children's Hospital.
A retrospective and descriptive study was performed from January 2008 to December 2016 in Hospital de Pediatría 'Prof. Dr. Juan Pedro Garrahan'. Patients under 18 years with clinical features, serological tests, cultures and/or histological findings compatible with histoplasmosis were included. Thirteen patients were selected (seven male and six female; mean age was 9 years with interquartile range 3.4-13); three children (23%) were from Buenos Aires province, three (23%) from Santa Fe province, and seven (54%) from other provinces.
In ten cases (77%) the clinical form was disseminated, and it was pulmonary in three (23%). Eight cases (62%) suffered other comorbidities. Serological tests were positive in seven patients (54%), with positive cultures obtained in nine patients (69%). Histological findings compatible with histoplasmosis were found in 10 cases (77%). All patients received treatment with amphotericin B (liposomal formulation in seven cases, deoxycholate in six), with 10 patients continuing with oral itraconazole. Three patients (23%) died from causes unrelated to histoplasmosis.
The majority of children in the series had comorbidities and disseminated histoplasmosis. Mortality was not directly associated with histoplasmosis.
