ABSTRACT
We studied the behavior of four major acute phase proteins (SAA, CRP, ACT and AGP) in pyrexial occurrences of 16 neutropenic patients with acute leukemia. Altogether 37 febrile episodes were recorded; 27 were infectious in origin (microbiologically documented infection and clinically documented infection, MDI/CDI group) and 10 were pyrexias of unknown origin (PUO group). In the MDI/CDI group the mean value for the highest individual SAA concentration was 282 +/- 161 mg/l and in the PUO group 95 +/- 79 mg/l. The corresponding mean values were 4.0 mg/l (range 0.2-5.5 mg/l) in 10 control patients with 1 year remission and 0.8 mg/l (range < 0.1-1.2 mg/l) in 30 healthy adults. The peak value of SAA rose above 100 mg/l in 85% of our MDI/CDI pyrexias and in 40% of PUO. More reliable results were obtained when the difference between the value on the day when pyrexia occurred and the previous day was calculated. In that case, the difference was above 75 mg/l in 23 of 27 (85%) MDI/CDI pyrexias and in none of 10 (0%) PUO. In the MDI/CDI group the mean difference was 204 +/- 137 mg/l while it was only 26 +/- 19 mg/l in the PUO group. The statistical significance was very high (p < 0.0001). The CRP monitoring was very inferior to SAA while ACT and AGP monitorings were unsatisfactory.

Tumor lysis syndrome is specific acute renal failure. This syndrome is usually a complication of cytostatic therapy in patients with acute lymphoblastic leukemia and lymphoblastic lymphoma. Tumor cell lysis following chemotherapy may lead to metabolic complications and renal failure. We report herein, two patients with acute lymphoblastic leukemia who developed tumor lysis syndrome after chemotherapy. Furthermore, we describe important measures to prevent tumor lysis syndrome in high risk patients.

Twenty-one newly diagnosed adult AML patients were treated with high dose Ara-C (HD-ARA-C) as a single induction treatment with the dose of 2 g/m2 q 12 hours x 12. Seventy-six percent (16/21) responded with complete remission. Three patients died in induction in pancytopenia, another one died on day 44 in CR due to bleeding of pulmonary aspergilloma. This treatment seems to be highly efficient for remission induction, but requires an adequate transfusion and other supportive measures. The overall toxicity was transient and seems acceptable. However, the remission duration is unacceptably short, the consolidation with the same treatment seems to be inadequate. More aggressive treatment in postinduction period seems to be warranted.
