ABSTRACT
Infection is a leading cause of mortality in hematology. Although data on nosocomial infections are available, little is known about events falling into the broader category of healthcare-associated infections. Our aim was to evaluate the incidence and causes of healthcare-associated infections in hematology patients, comparatively with nosocomial infections. Using predefined criteria, we classified 223 infectious episodes in 137 patients for their association with healthcare and nosocomial occurrence. Of the 223 infectious episodes, 204 (91%) were healthcare associated, 94/223 (42%) were also nosocomial, and 9% were community-acquired. Healthcare-associated infections should be preferred to nosocomial infections--which underestimates half of the healthcare-associated infections--as quality indicators for preventive programs.

We retrospectively studied 120 cases of chronic lymphocytic leukemia diagnosed between January 1988 and December 1998. The median age of our patients was of 66 years, 75% among them were male. The discovery of the illness was fortuitous in 20% of the cases, the peripheral adenopathy and the splenomegaly were noted respectively in 72 and 48% of the cases. The blood lymphocytosis was on average 51.109/1 with extremes of 5 and 818.109/1. Anemia was noted in 71% of the cases and a thrombopenia in 42%. Fifty patients were classified C stage of BINET and sixty elevated risk according to RAI. The therapeutic attitude was according to patient's age and the CLL stage. Thus, 94 patients received a chemotherapy and a complete or partial response was observed in 58 of the cases. The overall survival at 5 years were 47%. The retained prognostic factors were the stage according to the classifications of BINET and RAI, the thrombopenia and the lymphocytosis blood overhead 100.109/1.
