Background and Objective: Demyelinating lesions, widespread tissue damage, and neuronal connectivity impairments in white matter are associated with reduced cognitive decline in multiple sclerosis (MS) patients. These findings are particularly prominent in the corpus callosum of the brain. Interleukin-10 (IL-10) is an anti-inflammatory cytokine secreted by regulatory T cells (Tregs) with anti-inflammatory properties and can inhibit the production of pro-inflammatory cytokines produced by macrophages and T cells. IL-6 is a multifunctional cytokine involved in the immune system of autoimmune diseases. The IL-6 gene consists of 5 exons, 4 introns, and a proximal promoter region located on the 7p21 chromosomal locus in humans. This study aimed to determine the effects of IL-10 (-1082/-819) and IL-6 (-174) gene polymorphisms on corpus callosum changes in women with MS.
Methods: This case-control study was conducted on 40 women with MS aged 20-40 years referring to Golestan and Kowsar Magnetic Resonance Imaging (MRI) centers in Gorgan and 20 women without MS, autoimmune or inflammatory diseases over 40 years during 2015. Ten mL of blood was taken from the subjects for genotyping. Additionally, DNA extraction was performed using the phenol-chloroform method, and DNA genotyping was performed using the sequence specific primer-polymerase chain reaction (SSP-PCR) method. Brain MRI images of the subjects were employed to measure the corpus callosum and to investigate the relationship with the investigated polymorphisms.
Results: After performing the tests and obtaining different IL-6, IL-10 (-819), and IL-10 (-1082) genotypes, no significant statistical correlation was observed between IL genotypes in the case and control groups. Additionally, no significant correlation was observed between the different IL-6, IL-10 (-819), and IL-10 (-1082) genotypes and changes in the size of different parts of the corpus callosum, including rostrum width, splenium width, body width, the ratio of body length to anteroposterior length, and the ratio of body length to maximum height between the case and control groups. Reductions in the variables of rostrum width, splenium width, body width, the ratio of body width to anteroposterior length, and the ratio of body width to maximum height were significant in both case and control groups (P<0.05). Only the reduction in splenium width was significantly associated with the occurrence of MS (P<0.009, odds ratio [OR]=2.35, 95% confidence interval [CI]=4.51-1.22).
Conclusion: There was no relationship between the morphometric changes of reduced corpus callosum and the changes in IL-6, IL-10 (-819), and IL-10 (-1082) genotypes in patients with MS.
