Adenosine deaminase (ADA) activity rises in various body fluids in patients with tuberculosis. A prospective study was conducted to determine the diagnostic value of ADA activity in bronchoalveolar lavage. Between March 2001 and February 2003, 148 patients were enrolled in our study, mean age 55.6 years (SD 14.6), and a male to female ratio of 2.4:1. The mean duration of symptoms was 66.2 days. All patients were either sputum-smear negative for AFB or failed to produce sputum. The final diagnosis resulted in three patient groups: 43 with pulmonary tuberculosis, 70 malignancy, and 35 miscellaneous causes. The mean ADA activity in the bronchoalveolar lavage for the pulmonary tuberculosis, malignancy, and miscellaneous causes groups was 8.98 (95% CI, 3.79-14.17), 7.63 (95% CI, 4.12-11.14), and 11.61 U/l (95% CI, 3.59-19.62), respectively. No difference was detected in the ADA level in the pulmonary tuberculosis vs other groups (p=0.56, one-way ANOVA). A high level of ADA activity was found in non-tuberculous conditions such as bronchogenic carcinoma, pulmonary hemosiderosis, chronic pneumonia with empyema thoracis and chronic myeloid leukemia. We concluded that ADA activity in the bronchoalveolar lavage was not clearly diagnostic of smear-negative pulmonary tuberculosis. Early diagnosis required histopathology of biopsied transbronchial specimens obtained by fiberoptic bronchoscopy.

We have reported a case of hepatic adenomatosis associated with hormone replacement therapy (estrogen and progesterone) and hemosiderosis caused by excessive blood transfusion for the treatment of chronic myeloid leukemia. A 34-year-old woman was found to have several hepatic tumors on a routine medical examination. The general condition was good. Laboratory studies showed iron overload. Abdominal computed tomography and selective hepatic angiography showed several hypervascular tumors in the right lobe of the liver (up to 20 mm in diameter). Since hepatocellular carcinoma could not be ruled out, subsegmental hepatectomy was performed. Histopathological examination of the surgical specimen showed hepatic adenomatosis with hemosiderosis. Both hormone replacement therapy and iron overload could be the cause of hepatic adenomatosis.

Imatinib, a tyrosine kinase inhibitor has revolutionized the therapy of Philadelphia chromosome positive chronic myeloid leukemia. Side effects of imatinib include grade 1-4 hepatotoxicity in a subset of patients. We report the case of a 46-year-old male with chronic myeloid leukemia, who developed hepatic hemosiderosis during treatment with imatinib. After ruling out the established congenital and acquired causes of hepatic hemosiderosis, we attribute this to a possible side effect of imatinib therapy. This condition was successfully treated with periodic phlebotomy thus precluding discontinuation of imatinib. To our knowledge, this is the first report of hepatic hemosiderosis most likely consequent to imatinib therapy.
