The Association of Pre-diagnostic Inflammatory Markers and Adipokines and the Risk of Non-Hodgkin Lymphoma Development in Egypt

Non-Hodgkin lymphoma (NHL) is an etiologically, clinically, and histologically heterogeneous group of lymphoproliferative disorders. Immune dysfunction is a well-known risk factor and dysregulation of cytokines may mediate disease progression. Obesity is one of the important relations connecting immune system abnormalities and lymphomagenesis. We conducted a study to find out the association between obesity as measured by body mass index (BMI), and risk of non-Hodgkin lymphoma (NHL) development by assessment the of inflammatory cytokines levels, (IL-6, IL-10, IFN-gamma and CRP) and adipokines levels (leptin and adiponectin). Also, to predict the effect of higher BMI on the incidence of NHL. The study included 180 NHL patients and 172 healthy controls. The inflammatory markers (IL-6, IL-10, IFN-γ & CRP) together with adiponectin were assessed by ELISA technique. IL-6, IL-10, CRP, IFN-γ and Adiponectin were statistically higher in cases than control. A positive significant difference of Leptin (p-value 0.001) was found with higher levels in patients with BMI (≥ 25 kg/m2) than in patients with < 25 kg/m2. IL-6, IL-10, CRP, IFN-γ and Adiponectin could be implicated in lymphomagenesis in Egyptian NHL. The study results support the hypothesis that obesity has a major role in the development of NHL. An association between Leptin and NHL risk with higher levels in patients with BMI (≥ 25 kg/m2) was proved.
