Clinical markers of immune disorders in the pathogenesis of Escherichia coli enteritis

Background. Escherichia coli enteritis is one of the most common causes of diarrhea in developed countries and is caused usually by pathogenic strains of Escherichia coli. Objectives. To investigate the role of reactive response of polymorphonuclear neutrophilic granulocytes (NG) of peripheral blood in the systemic inflammatory response mechanisms of acute Escherichia enterocolitis (AEC), depending on genes polymorphism of heat shock proteins (HSP) family 70-2 (HSP70-2, 1267A®G) and interleukin 10 (IL-10, C-592A). Material and methods. The genes polymorphism was analysed by PCR based method in 95 patients with AEC and 30 healthy individuals. Clinical markers of immune disorders were evaluated after hematological indices, based upon an extended general clinical blood analysis, using verified formulas. Results. The endogenous intoxication severity did not depend reliably on genotypes of IL-10 gene (rs1800872), however it was significantly 23.68% (р=0.043) higher in GG-genotype carriers of HSP70-2 gene (rs1061581). The reduction of cellular reactivity by 14.71-19.08% (р<0.01) did not depend on the analyzed genes genotypes. But general non-specific immune reactivity decreases 3.49-4.24 times (р<0.001) was deeper in GG-genotype carriers of HSP70-2 gene and AA-genotype carriers of IL-10 gene by 17.78% (р=0.009) and 12.37% (р=0.023) respectively. The immunologic resistance index was lower by 18.75% (р=0.024) in GG-genotype carriers than in patients with А allele. Conclusions. Hematological indices, based upon an extended general clinical blood analysis, are indicative and reliable non-specific clinical markers of immune disorders in case of AEC

The polymorphism of Matrilin-3 (RS77245812) and Interleukin-10 (RS1800872) genes in osteoarthritis patients with arterial hypertension, obesity and type 2 diabetes mellitus

Introduction. Osteoarthritis (OA) is a multifactorial disorder in which ageing, genetic, hormonal and mechanical factors are major contributors to its onset and progression. Objectives. To evaluate the genotypes frequencies of Matrilin-3 (MATN3, rs77245812) and Interleukin-10 (IL-10, rs1800872) genes polymorphism in OA patients combined with arterial hypertension (AH), abdominal obesity (AO) and type 2 diabetes mellitus (DM2). Methods. The polymorphic variants of genes MATN3 (C908T) and IL-10 (C-592A) were analyzed by PCR in 74 OA patients with AO, AH, DM2 and 25 healthy individuals. Results. Distribution of MATN3 gene polymorphic variants in observed groups was as follows: CC-genotype – in 94.59% OA patients, and in 96.0% of control (p>0.05); CC-genotype – in 5.41% and 4% respectively. The C-allele prevails over T-allele by 94.95% (p0.05); CA-genotype – in 37.84% vs 32.0% (p>0.05) respectively; CC-genotype was found in 9.46% OA patients and none of control. C-allele of IL-10 gene dominated over the A-allele: among patients – 2.52 times (p<0.001), among control group – 5.25 times (p<0.001). The wild C-allele of IL-10 gene dominated 2.96 times (p<0.001) generally in the observed population. Conclusions. Polymorphic variants of genes MATN3 and IL-10 are not additional risk factors of the OA occurrence in the observed population of Northern Bukovina
