Abstract
- Older adults are mostly affected by chronic lymphocytic leukemia (CLL). The present study aimed to evaluate oxidative stress in CLL and to assess its impact on IL-9, Th9 cells levels and prognosis of cases. Seventy Egyptian CLL patients and 15 healthy controls were included. Th9 cell and immunophenotyping of abnormal B cells were assessed by flow cytometry, IL-9 level using ELISA, IL-9 mRNA by qRT-PCR, cytogenetics using FISH, and oxidative stress parameters were determined spectrophotometrically and with native gel electrophoresis. Oxidative stress was elevated in CLL that correlated with abnormal immunophenotyping, cytogenetic changes, bad prognosis, Th9 cells, and overexpression of IL-9. Levels of IL-9 and Th9 cells were strongly correlated with oxidative stress and bad prognostic markers in CLL, indicating that these cells may contribute to CLL by novel mechanisms that could include oxidant injury.
