Hepatic involvement in pediatric patients with paracoccidioidomycosis: a clinical and laboratory study

The liver is one of the organs most affected by paracoccidioidomycosis, a systemic mycosis endemic in some Latin American countries. The majority of articles focused on adult populations and failed to describe any detailed experience of liver abnormalities in pediatric patients. Therefore, the aim of this study was to describe the frequency and characteristics of liver involvement in children with paracoccidioidomycosis. This study comprised 102 patients less than 16 years of age (median 104.3 months) diagnosed with paracoccidioidomycosis from 1980 to 2010. Diagnosis was established by the identification of fungus. Forty-one patients had liver involvement. The main clinical features were generalized lymph node enlargement (39/41), weight loss (34/41) and fever 32/41). Approximately, one-third of the patients had jaundice. Patients with hepatic involvement were younger. A predominant elevation of canalicular enzymes occurred. There was a statistically significant difference in albumin (p < 0.001) and hemoglobin (p = 0.002) values between patients with and without liver involvement, and the lowest values were found in the former group. Cutoff levels of albumin (<3.05 g/dL) and hemoglobin (<9.2 g/dL) can be used to infer hepatic involvement. Hypoalbuminemia (median 2.4 g/dl) is more severe in patients with hepatic involvement and may indicate a worse liver function or complication of the disease (intestinal lymphangiectasia). Deaths (6) occurred only among patients with liver involvement. Particular clinical and laboratory characteristics are present in pediatric patients with hepatic involvement. Younger patients and those with severe hypoalbuminemia are more likely to present liver involvement by Paracoccidioides brasiliensis.
