heal.abstractAim: To investigate the cellular and humoral immunity status of gliomas, and their association with the WHO grading system. Material and methods: We have conducted a case-control study of 49 patients with gliomas and 30 healthy controls. We used ELISA assays, radial immunodiffusion, indirect immunofluorescence, latex test and flow cytometry assays to estimate preoperative in serum the immunological profile. Results: Patients with glioma had significantly reduced amounts of 112 (p=0.000), TNF-a (p=0.033), IgG (p=0.011), IgA (p=0.027),C4 (p=0.026),CD3+ (p=0.001), CD4+ (p=0.000), CD8+ (p=0.002), ratio CD4/CD8 (p=0.000), CD19+ (p=0.04) and elevated 110 (p=0.05) compared with healthy controls. No statistically significant differences were observed concerning viral agents, total NK cells, IgM, IgE, IL16, granzyme-b, RF, ANA, ENA, anti-dsDNA and anti-cardiolipin antibodies. A higher WHO grade, after controlling for age and gender, was associated with decreased number of CD3+ (p=0.011), CD4+ (p=0.015), CD8+ (p=0.048) and ratio CD4/CD8 (p=0.027), as well as with decreased 112 (p=0.018), C4 (p=0.02), and IgG (p=0.05) IL2 and CD4+ counts were significant predictors of grade. Conclusions: A shift from Th1 to Th2, a CD3+ and CD19+ lymphocytopenia, a diminished fraction CD4/CD8 and a reduced amount of immunoglobulins and complement were observed in the patients with gliomas. A higher WHO grade of the tumor was associated with greater impairments of immunity. Since defects of both humoral and cellular immunity were equally observed and significant predictors of grade were assessed, a preoperative evaluation of the immune system of patients with gliomas is being proposed.
