Interleukin-10 (IL10) may contribute to the development of non-Hodgkin's B cell lymphoma, especially in the context of acquired immunodeficiency syndrome (AIDS), where lymphoma incidence is greatly increased. Utilizing specimens from the Multicenter AIDS Cohort Study (MACS) obtained prior to diagnosis of AIDS-associated lymphoma, detectable serum human IL10 was seen much more frequently in lymphoma cases (n = 61, 26%) compared to CD4-matched AIDS controls (5%, P = 0.004), or to HIV-infected (2%, P = 0.002) or HIV uninfected subjects (0%, P = 0.0003). In longitudinal studies, detectable IL10 occurred at times closest to but preceding lymphoma diagnosis (P = 0.01). In an independent genetic analysis of single-nucleotide polymorphisms within the promoter region of the IL10 gene in 1157 MACS subjects, a high IL10-expressing genotype (-592 C/C) was overrepresented among lymphoma subjects (P = 0.009), even when controlling for race (P = 0.006). These results suggest that elevated serum IL10 or the IL10 promoter -592 C/C genotype are associated with development of AIDS lymphoma.
