Disseminated infection with Cryptococcus neoformans var neoformans in an 8 years immunocompetent girl.

ABSTRACT

Disseminated cryptococcosis is a rare and often fatal disease in children. The majority of cases usually occur in individuals with defective cell-mediated immunity, most commonly due to HIV infection. The authors here in report an 8-year-old girl from Nepal who presented with fever, cough, headache, lymphadenopathy, hepatosplenomegaly and cutaneous lesions. Lymph node biopsy revealed multiple granulomas composed of histiocytes and epitheliold cells along with numerous yeast forms of cryptococcus. Cultures of CSF, sputum and urine yielded cryptococcus neoformans. Surprisingly,the immune function in terms of T-cell number, CD4 CD8 ratio, serum immunoglobulins and HIV serology was normal. After the diagnosis of disseminated cryptococcosis was established, the patient was treated with 5-fluorocytosine (100 mg/kg/day) for initial two weeks and amphotericin B (1 mg/kg/day) for 13 weeks. Patient responded well to the treatment with disappearance of presenting symptoms, cutaneous lesions, and lymphadenopathy, though she still had hepatosplenomegaly, which also decreased. Unfortunately, she developed loss of vision in 10th week of therapy. The patient was discharged on oral fluconazole (6 mg/kg/day) and no recurrence was found during the follow-up period of more than 9 months. This is the first case of disseminated cryptococcosis with no detectable immune deficit, from India.
