(Zhang L. et al., 2022) performed cytokine assays in 229 newly diagnosed NHL patients and 40 healthy adults, and found that IL-6, IL-8, IL-10, tumor necrosis factor (TNF)-β, IFN-γ, CRP, and PCT levels were higher in NHL patients with respiratory infections than in those without infections, and patients with both respiratory infections and bacteremia had higher IL-6. This evidence concerns the gene CALCA and respiratory tract infectious disorder.
