Abstract:
Analysis of T lymphocytes cytokine profiles allows to differ subpopulations: Th1, Th2, Th3, Tr1. Aim of the study was to assess Th1/Th2 balance in acute lymphoblastic leukemia in children at diagnosis and during/after remission induction, especially during infections. Percentages of lymphocytes T producing IFN-gamma and IL-4 were assessed by flow cytometry. We noted the rise of lymphocytes T helper producing IFN-gamma (Th1) and percentage of lymphocytes T producing IL-4 at the beginning and during remission induction was higher than in control group. During fever/infection we observed the rise of lymphocytes Th1, and no change in Th2 percentage. Summarizing we suggest Th1/Th2 imbalance and Th2 predominance in acute lymphoblastic leukemia in children.

Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
