Abstract
The relationship between plasma lipid levels and mortality from cardiovascular diseases has been shown in many studies, but there has been far less investigation into their relationship to non-cardiovascular diseases. The aim of this study was to investigate the lipid profile of individuals with hematological malignancies and its relationship to disease activity. 238 patients were included in the study: 84 with acute leukemia, 62 with non-Hodgkin lymphoma, 35 with Hodgkin's lymphoma, 32 with multiple myeloma, and 25 with myeloproliferative syndrome. The HDL cholesterol level of the patients differed to that of the individuals in the control group in the active disease period for all the analyzed disorders, but only remained statistically significant in the acute leukemia and non-Hodgkin lymphoma groups during the remission period. Smaller differences were observed for the remaining lipid fractions, except for the triglyceride level, which increased in the active disease period in all the analyzed disorders except non-Hodgkin lymphoma. The most pronounced changes in the lipid fractions occurred in the HDL cholesterol level, and were the most remarkable for acute leukemia.
