A 60-year-old man was diagnosed as adult T-cell leukemia with severe hypercalcemia because of production of parathyroid hormone-related protein. After admission, the patient had respiratory insufficiency with an infiltrative shadow in his lungs suggestive of pneumonia. However, neither improvement in respiratory function nor disappearance of the abnormal chest shadow was observed with administration of various antibiotics. An autopsy demonstrated the chest shadow had been caused by metastatic calcification associated with hypercalcemia due to production of parathyroid hormone-related protein. The possibility of metastatic calcification should be considered in patients with adult T-cell leukemia and hypercalcemia who have an abnormal chest shadow.

The efficacy of two different high-dose treatment of IFN-α2b was evaluated in this study. Serum hepatitis C virus (HCV) RNA levels were semi-quantified by simplified reverse transcription-polymerase chain reaction. Seventy-one patients with chronic hepatitis C received 10 million units of IFN-α2b daily for 2 weeks or trice a week for 24 weeks. Alanine aminotransferase (ALT) levels overall normalized in 78.1% and 51.6% of the cases at the end of the therapy and 6 months after that, respectively. HCV RNA disappeared in 71.9% and 35.7% of the patients at the end of the therapy and 6 months after that, respectively. There was no significant difference between the 2 different regimes. The efficacy of the treatment was fair in cases in which the pretreatment level of the viral amount was low. The results of this study indicate that daily administration of IFN in the first 2 weeks during 6-month course does not increase the efficacy of the therapy in such a high-dose treatment regime.

A 69-year-old female was admitted to our hospital because of leg edema, proteinuria (2.1 g/day), and gross hematuria. She had non-alcoholic liver cirrhosis of unknown etiology. Esophageal varices also were found. Examination of the renal biopsy specimen revealed mesangial proliferative glomerulonephritis with IgA deposits. Propranolol was administered orally to reduce portal hypertension, resulting in a progressive decrease in urinary microalbumin excretion. This case suggests that portal hypertension is involved in the pathogenesis of IgA nephropathy in liver cirrhosis.
