Abstract

Capsule-deficient Cryptococcus naoformans (CN-CD) infection is very rare. The authors recently experienced the case of CN-CD infection with the complication of the syndrome of inapropreate antidiuretic hormone secretion (SIADH) in a 83 year old woman. She was admitted to our hospital with the complaints of fever and general fatigue on June 10, 1987. At the time of admission, there were no abnormal findings except a mildly lowered conciousness level on physical examination, there were no abnormal neurlogical finding nor menigeal signs. Labolatory data revealed a mild leukocytosis and hyponatremia. Chest X-P showed a few small nodular shadows scattered in both lungs. Antibiotics therapy was of no help and hyponatremia became worse. Then with the suspicion of SIADH, Demeclocycline was administered and limitation of water intable was decreased and hyponatremia improvement was used. Yeast-like fungi was detected in the venous blood culture and in the cerebrospinal fluid (cell count: 252/3) CN-CD by India-ink preparation and bacteriological nature were determined. We made a diagnosis of sepsis and meningitis by CN-CD accompanied with SIADH. In spite of Miconazole administration intravenously and intrathecally, she died 2 months after admission.
The minimal inhibitory concentration (μg/ml) of antibiotics against the isolated CN-CD was as follows: Amphotericin B: 0.78, 5-PC: 1.56, Miconazole≤0.05, Nystatin: 25, Ketoconazole: 0.78.
