A Case of Tansient Hyperphosphatasemia

ABSTRACT

We examined a male infant with transient increase in alkaline phosphatase(ALP) activity. The 25-month-old infant was admitted to a local hospital because of pneumonia of unknown etiology. Initial laboratory investigation revealed a serum ALP of 11,260U/L, which was comparable to that of bone isoenzyme on the electrophoresis pattern, There was no evidence of hepatitis, skeletal or intestinal diseases. The hyperphosphatasemia disappeared 3 months later. We report a case of transient hyperphosphatasemia diagnosed inci- dentally in the course of management of pneumonia.
