Toll-Like Receptor 2 (TLR-2) Gene Polymorphisms in Type 2 Diabetes Mellitus

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 Arg753GIn variants in T2DM pathogenesis

Inflammation, Left Ventricular Mass Index and Chronic Renal Failure in Diabetic Patients

Aim: The aim of this study was to determine the relationship between left ventricular hypertrophy (LVH) and inflammatory markers in patients with type 2 Diabetes Mellitus (T2DM) with diabetic nephropathy at different stages

Clinical, biochemical and histological correlations in a group of non-drinker subjects with non-alcoholic fatty liver disease

The correlation between biochemistry, imaging-studies and histology is a matter of controversy in non-alcoholic fatty liver disease (NAFLD) and the major pathophysiology of non-alcoholic steatohepatitis (NASH) is still unknown. We aimed to perform a comparative analysis between clinical, biochemical and histological variables of NAFLD. One-hundred and five NAFLD patients (F/M : 51154), were studied, all with no-alcohol intake. The groups were followed-up for six months

Investigation of DNA repair gene variants on myelodysplastic syndromes in a Turkish population

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

Cox-2 gene polymorphisms in Turkish patients with myelodysplastic syndrome

Cyclooxygenase-2 gene polymorphisms have been studied and known its role one on cancerogenesis even though there has not yet been any studies myelodysplastic syndrome. We aimed to provide the first data on COX-2 gene polymorphisms in myelodysplastic syndrome. A total of 39 patients with MDS and 50 healthy controls were recruited from undertaken hematology departmentand compared in terms of COX-2-765 G -> C and COX-2-1195 A. G genes. Statistically significant difference was observed between patients with MDS and controls in terms of COX-2-765 G -> C genotype and distribution of alleles and COX-2-765 GG genotype was more frequently found in the MDS group (P<0.001). Moreover, COX-2-765 C+(CC+CG) genotype was found to provide 5.6 times more protection against MDS. In conclusion, our results indicate that polymorphisms of the C allele of the COX-2 gene may provide protection against MDS; however, its predictive value and potential as a marker in oncology remain to be investigated in further trials

Prophylactic Central Nervous System Irradiation Is Not Indispensable in Adult Patients with Acute Lymphoblastic Leukemia: A Multicenter Retrospective Cohort Study

Objective: Studies comparing the efficacy and safety of prophylactic regimens for central nervous system (CNS) involvement in acute lymphoblastic leukemia (ALL) are scarce in adults. This multicenter retrospective study aimed to compare the efficacy of prophylactic regimens with and without CNS irradiation on the development of CNS relapse during follow-up. Materials an

Hematopoietic Stem Cell Transplantation for Patients with Paroxysmal Nocturnal Hemoglobinuria with or without Aplastic Anemia: A Multicenter Turkish Experience

Objective: Although inhibition of the complement system at different steps is a promising therapy modality in patients with paroxysmal nocturnal hemoglobinuria (PNH), allogeneic hematopoietic stem cell transplantation (HCT) is still the only curative therapy, especially for patients with intractable hemolysis or bone marrow failure. The aim of this study is to evaluate the outcomes of allogeneic HCT in PNH patients with aplastic anemia (PNH-AA) or without
