RESUMO
OBJECTIVE: Diabetes is a chronic, broad-spectrum metabolic disorder that requires continuous medical care, in which the organism cannot adequately benefit from carbohydrates, fats, and proteins due to insulin deficiency or defects in the effect of insulin. Vascular complications are considered to be the main cause of mortality in diabetic patients. Platelet activation plays a role in the development of vascular complications. The aim of this study was to evaluate the relationship between HbA1c, which is the parameters that we can evaluate in primary healthcare institutions, and increased Mean Platelet Volume (MPV) and Platelet Distribution Width (PDW) levels, which are thought to be a platelet activation markers in patients with Type 2 diabetes mellitus. METHODS: In our study, the data for 600 patients who applied to Internal Medicine outpatient clinic of our hospital between January 01, 2022, and June 31, 2022, were obtained by examining their epicrisis through the hospital information management system. Six hundred patients, including 300 control group with HbA1c level below 6.5 and 100 patients each 7-8.5 8.5-10 and above 10, were included in the study. HbA1c, MPV, and PDW levels of the patients were recorded. RESULTS: Among 600 patients who applied to internal medicine polyclinics of our hospital between January 01, 2022, and June 31, 2022, 412 participants were female, while 188 participants were male. It was determined that the participants were 46.91±12.68 years old on average, the youngest participant was 18 years old and the oldest participant was 66 years old. It was determined that the mean HbA1c value of the participants participating in the study was 7.6±2.4, the lowest HbA1c value was 4.3, and the highest HbA1c value was 19.3. It was determined that the mean MPV value of the participants was 10.1±1.1, the lowest MPV value was 7.7, and the highest MPV value was 13.3. It was determined that the mean PDW value of the participants was 16.0±0.4, the lowest PDW value was 14.8, and the highest PDW value was 17.2. CONCLUSION: In this study, it was determined that MDV and PDW levels showed a statistically significant difference according to the HbA1c value ranges of the patient group. Accordingly, the MPV and PDW levels of the participants whose HbA1c value range is >10 are higher. It was observed that MPV and PDW levels increased as the HbA1c value range increased.
RESUMO
OBJECTIVE: Innate immunity factors are associated with type 2 diabetes (T2DM) and its complications. Therefore, T2DM has been suggested to be an immune-dependent disease. Elevated fasting glucose level and higher concentrations of innate immunity soluble molecules are not only related with insulin resistance, but inflammation is also an important factor in beta cell dysfunction in T2DM. Toll-like receptor 2 (TLR-2), which has an important role in inducing innate immune cells, is thought to have suppressive roles on immune responses in T2DM. We therefore aimed to investigate the possible role of TLR-2 del -196-174 and Arg753Gln variants in T2DM pathogenesis. MATERIALS AND METHODS: This study was designed as a case-control study. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique was used to genotype the two variants in 100 T2DM patients and 98 agematched controls. RESULTS: We found significantly higher frequencies of TLR-2 del -196-174 DD genotype (P=0.003), ID genotype (P=0.009) and D allele (P=0.001) in patients compared with controls. In addition, the II genotype (P=0.001) and the I allele (P=0.003) frequencies were elevated in healthy controls. We did not find any significant differences in frequency distribution for the Arg753Gln variant in study groups. CONCLUSION: We suggest that carrying the D allele of the TLR-2 del -196-174 variant may be related as a risk factor for T2DM.
RESUMO
The aim of this study was to assess the possible influence of genetic polymorphisms in hOGG1, XRCC1, XRCC3, XPD, XPG and APE1 on the observed DNA damage in a group of Turkish myelodysplastic syndrome (MDS) patients. A total of 39 patients with myelodysplastic syndrome and 78 age-matched healthy control subjects were included in our study. Polymerase chain reaction/restriction fragment length polymorphism analysis was performed for the detection of DNA repair gene variants. No significant differences in DNA repair enzymes APE1, XRCC1 and XPG were found between MDS patients and controls. On the other hand, XRCC3, XPD and hOGG1 were associated with an increased risk of MDS (p=0.004, p=0.000, p=0.017, respectively). Specifically, Thr/Met genotype was more relevant in patients (p=0.026) in XRCC3; in hOGG1, Cys+ genotype was found higher in patients (p=0.017); and in XPD, Gln/Gln genotypes were found higher in the patient (p=0.001). In conclusion, XRCC3, XPD and hOGG1 genotypes are associated with an increased MDS risk, suggesting their possible involvement in the pathogenesis and biology of this disease.
