Abstract
Introduction: Multi-drug resistant tuberculosis (MDR TB) is a significant health problem in some parts of the world. Three major
cytokines involved in TB immunopathogenesis include IL-2, IL-4 and IL-10. The susceptibility to MDR TB may be genetically
determined. The aim of the study was to assess the association of IL-2, IL-4, IL-10 gene polymorphisms with multi-drug resistant
tuberculosis (MDR TB) in Ukrainian population.
Material and methods: We observed 140 patients suffering from infiltrative pulmonary tuberculosis (PT) and 30 apparently
healthy subjects. The patients were assigned to two groups whether they suffer or do not suffer from pulmonary MDR TB. Interleukin
gene (IL) polymorphisms, particularly T330G polymorphism in the IL-2 gene, C589T polymorphism in the IL-4 gene and
G1082A polymorphism in the IL-10 gene were studied through polymerase chain reaction. Circulating levels of IL-2, IL-4 and IL-10
in venous blood were estimated using ELISA.
Results: Prior to treatment, patients with PT showed significant increase of IL-2 levels and decrease of IL-4 and IL-10 levels compared
to apparently healthy subjects. Circulating IL-4 and IL-10 levels were significantly decreased whilst serum IL-2 level was
significantly increased in patients with MDR TB compared to non-MDR TB. Low IL-4 and IL-10 secretion and considerable IL-2 alterations
were shown to be significantly associated with mutations of homozygous and heterozygous genotypes affecting C589T polymorphism
in the IL-4 gene, G1082A polymorphism in the IL-10 gene and T330G polymorphism in the IL-2 gene in patients with PT.
Conclusions: Heterozygous genotype and mutations homozygous genotypes gene in polymorphisms determining specified
cytokines’ production is a PT risk factor and may lead to disease progression into chronic phase. Heterozygous genotype of
aforementioned cytokine genetic polymorphisms was significantly the most frequent in patients with MDR TB.
