The purpose of this study is to explore why type 2 diabetes mellitus (T2DM) patients are susceptible to pulmonary tuberculosis through detection of serum Toll-like receptor 4 (TLR4), an important immune-related receptor, especially in terms of content and TLR4gene polymorphism. Patients with T2DM complicated by pulmonary tuberculosis (T2DMTB) were selected as the case group and T2DM patients without tuberculosis were selected as the control group. Forty patients in each group were randomly selected and their serum TLR4levels were detected and compared. Determination of six sites of TLR4gene polymorphism was carried out in 238 T2DMTB patients and 310 patients with T2DM, and results showed that the serum TLR4content of the T2DMTB group was significantly lower than that of the T2DM group (p<0.05). The six sites of TLR4gene polymorphism did not show significant associations with T2DMTB risk. No statistically significant differences in genotype distributions were observed between T2DMTB patients and patients with T2DM when studied using the recessive and dominant genetic models. How two diseases with contradictory nutritional statuses can occur in the same person is difficult to explain from environmental factors perspective alone. Future research should study the causes of T2DMTB from the perspective of genetics.

Background: The most chronic disease prevalence in the Iraqi population are type-2 diabetes mellitus (T2DM) and hypertension (HT). One of the important causes of these chronic diseases is obesity. Resistin (RETN) is a major link between obesity and insulin resistance (IR) or T2DM (which induces IR). The action of RETN on IR is mediated by Toll-like receptor-4 (TLR4). TLR4 is a putative RETN receptor that has been suggested to participate in RETN-inducing inflammation and IR. Objectives: To study the association between serum RETN/TLR4 and IR in hypertensive patients with or without T2DM subjects. Methods: This cross-sectional study was conducted on 120 men that classified into four different groups. These groups consist of the following: 30 apparently control group, 30 patients with hypertension, 30 patients with T2DM but without HT and 30 hypertensive patients with T2DM. For all the subjects, serum RETN, TLR4 and serum insulin was estimated by using the ELISA technique. Results: Our results showed that mean levels of the serum RETN and TLR4 were significantly elevated in all patient groups when compared with the control group. Also, a positive correlation between serum RETN and TLR4 was found in hypertensive patients with T2DM patients. Conclusions: Serum RETN and TLR4 were higher in all patient groups when compared with the control group. In addition, a positive correlation between RETN and IR in all study groups was noted. Then, we suggested a close association between RETN and TLR4 and their positive correlations with IR.

ABSTRACTThe platelet endothelial cell adhesion molecule 1 (PECAM-1) plays an important role in many inflammatory processes, including the development of atherosclerosis. Polymorphism rs668 of the PECAM-1 gene (373C/G) is functional, and it was reported to be associated with increased serum levels of PECAM-1. We investigated the association between the rs668 polymorphism of PECAM-1 and subclinical markers of carotid atherosclerosis in subjects with type 2 diabetes mellitus (T2DM). Five hundred and ninety-five T2DM subjects and 200 control subjects were enrolled. The carotid intima-media thickness (CIMT) and plaque characteristics (presence and structure) were assessed ultrasonographically. Biochemical analyses were performed using standard biochemical methods. Geno-typing of the PECAM-1 gene polymorphism (rs668) was performed using KASPar assays. The control examinations were performed 3.8 ± 0.5 years after the initial examination. Higher CIMT was found in patients with T2DM in comparison with subjects without T2DM. Statistically sig-nificantly faster progression of the atherosclerotic markers was shown in subjects with T2DM in comparison with the control group. When adjusted to other risk factors, the rs668 GG genotype was associated with an increased risk of carotid plaques in subjects with T2DM. We concluded that our study demonstrated a minor effect of the rs668 PECAM-1 on markers of carotid atherosclerosis in subjects with T2DM.

Abstract Background: Previous studies have shown that chemerin has important roles in the development of obesity, insulin resistance, metabolic syndrome, polycystic ovary syndrome (PCOS) and T2DM. The main goal of our study was to investigate the role of Chemerin rs17173608 gene polymorphism in T2DM (type 2 diabetes mellitus). Materials and methods: 100 patients with T2DM and 50 healthy volunteers were included in the present study. DNA isolation from blood samples was performed with K1820-02 DNA Mini Kit. Chemerin gene polymorphism was detected by Tetra- Amplification Refractory mutation system polymerase chain reaction (T-ARMS-PCR). At the end of T-ARMS-PCR, samples were run using gel electrophoresis. Some samples were validated by sequence analysis. Results: In the genotype analysis, 18.0% of patients had TT genotype and 81.0% of TG genotype was detected. GG genotype was not detected in any patient. Genotype of 1 patient was unidentified. Genotype distribution of healthy control group was 12.0% TT genotype and 88.0% TG genotype. Similar to the T2DM group, the GG genotype was not detected in the control group. There was no statistically significant difference between T2DM group and healthy control group for TG and TT genotypes. Conclusion: To our knowledge, chemerin rs17173608 gene polymorphism has been investigated in T2DM for the first time herein. In the present study, the TT genotype ratios were higher in the T2DM subjects than in healthy subjects. G allele frequency in the T2DM group was lower than that in the control group. However, there was no statistically significant difference between the groups.

Background. The course of type 2 diabetes mellitus (T2DM), obesity and chronic pancreatitis (CP) in most cases is not isolated, so it requires broadening the knowledge about the pathogenetic links at their combined course. Despite significant advances in genome research, most of the genetic factors that cause development of T2DM are still unclear. Objective. The aim of the study was to establish the prevalence of IRS1 gene polymorphism in the patients with T2DM as well as obesity and CP. Methods. The study involved 34 patients with T2DM who were hospitalized in the endocrinology department of Ternopil University Hospital in 2019-2020 and 10 apparently healthy patients. Analysis of IRS1 gene polymorphism (SNP in the promoter region - rs2943640; gene localization 2q36.3) was performed on the basis of polymerase chain reaction data using specific primers. Results. It was found that the frequencies of the genotype responsible for C/A polymorphism of IRS1 gene in T2DM, T2DM with obesity and in the combined course of T2DM with obesity and CP did not deviate significantly from the Hardy-Weinberg equilibrium (p>0.05). The patients with combined course of T2DM, obesity and chronic pancreatitis experienced a probable influence of genotypes C/C and C/A of IRS1 gene on the development of the studied comorbidity (p<0.05), which is confirmed by a probable difference in the dominant model of IRS1 gene inheritance only when T2DM was combined with obesity and CP compared to the control group (p<0.001). Conclusions. The presence of the C allele in both homozygous and heterozygous states may increase the risk of T2DM comorbidity, obesity and CP in the population of Ternopil region.

Abstract. Background: The study was designed to test the possible association between either polymorphisms of the matrix metalloproteinase-9 (MMP-9) gene (rs17576, rs3918242) or the MMP-3 5A/6A gene polymorphism (rs3025058) with markers of carotid atherosclerosis in patients with type 2 diabetes mellitus (T2DM). The second aim of the study was to demonstrate an association between either the rs17576, rs3918242 or rs3025058 and subclinical markers of coronary artery disease in the same subset of patients with T2DM. Patients and methods: A total of 595 subjects with T2DM and 200 subjects without T2DM (control group) were enrolled in the prospective study. Subclinical markers of carotid atherosclerosis were assessed ultrasonographically. Additionally, in a subset of subjects with T2DM a coronary computed tomography angiography (CCTA) was performed for diagnostic purposes. Genotyping of all three polymorphisms (rs17576, rs3918242, rs3025058) was performed with real-time PCR systems. Results: The comparison of atherosclerosis parameters was performed with regard to different genotypes of MMP-9 rs17576, rs3918242, and MMP-3 rs3025058 polymorphisms upon enrolment and during follow-up. In our study, we found an association between the MMP-3 rs3025058 and CIMT at the time of recruitment. Multiple linear regression analysis revealed the association of either the A- allele or the A- genotypes of the rs3025058 (MMP-3) with carotid intima media thickness (CIMT) progression in a 3.8-year follow-up. We demonstrated the effect of the rs3025058 on subclinical markers of coronary atherosclerosis (coronary calcium score, number of coronary arteries with more than 50 % stenosis, and presence of at least one vessel with more than 50 % stenosis). Conclusions: We found an association between the MMP-3 rs3025058 and subclinical markers of carotid (CIMT) and coronary atherosclerosis at the time of recruitment. Moreover, we demonstrated the effect of the MMP-3 rs3025058 on CIMT progression in the 3.8-year follow-up in patients with T2DM.
