Gene Polymorphisms and IL-10 Serum Levels in Patients with Multiple Sclerosis in Lithuania.

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system with features of demyelination and axonal degeneration at a young age. Genetic factors may play an important role in the development of multiple sclerosis. (1) Objective: To investigate IL-10 rs1800871, rs1800872, rs1800896, and IL-10 serum levels in patients with multiple sclerosis. (2) Methods: Our study included patients with multiple sclerosis (n = 127) and healthy volunteers (n = 195). The subjects’ DNA was extracted from peripheral blood leukocytes and genotyped by real-time polymerase chain reaction. The results were analyzed using the program “IBM SPSS Statistics 27.0”. (3) Results: The IL-10 SNPs were analyzed between the MS and control groups; however, no statistically significant results were found. The serum levels of IL-10 in the groups of MS and healthy subjects were not statistically significantly different (median (IQR): 0.828 (1.533) vs. 0.756 (0.528), p = 0.872). (4) Conclusions: IL-10 rs1800871, rs1800872, and rs1800896 and serum IL-10 levels are not likely to be associated with MS development. However, individuals carrying the rare haplotypes of rs1800871, rs1800872, and rs1800896 were associated with increased odds of MS (p = 0.006).
