Proteomics is a powerful approach to study the molecular mechanisms of cancer. In this study, we aim to characterize the proteomic profile of gastric cancer (GC) in patients with diabetes mellitus (DM) type 2. Forty GC tissue samples including 19 cases from diabetic patients and 21 cases from individuals without diabetes (control group) were selected for the proteomics analysis. Gastric tissues were processed following the single-pot, solid-phase-enhanced sample preparation approach—SP3 and enzymatic digestion with trypsin. The resulting peptides were analyzed by LC-MS Liquid Chromatography—Mass Spectrometry (LC-MS). The comparison of protein expression levels between GC samples from diabetic and non-diabetic patients was performed by label-free quantification (LFQ). A total of 6599 protein groups were identified in the 40 samples. Thirty-seven proteins were differentially expressed among the two groups, with 16 upregulated and 21 downregulated in the diabetic cohort. Statistical overrepresentation tests were considered for different annotation sets including the Gene Ontology(GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), Reactome, and Disease functional databases. Upregulated proteins in the GC samples from diabetic patients were particularly enriched in respiratory electron transport and alcohol metabolic biological processes, while downregulated proteins were associated with epithelial cancers, intestinal diseases, and cell–cell junction cellular components. Taken together, these results support the data already obtained by previous studies that associate diabetes with metabolic disorders and diabetes-associated diseases, such as Alzheimer’s and Parkinson’s, and also provide valuable insights into seven GC-associated protein targets, claudin-3, polymeric immunoglobulin receptor protein, cadherin-17, villin-1, transglutaminase-2, desmoglein-2, and mucin-13, which warrant further investigation.

Background: We sought to establish the in-shoe plantar pressure distribution during normal level walking in type 2 diabetic patients of Chinese, Indian, and Malay descent without clinical evidence of peripheral neuropathy. Methods: Thirty-five patients with type 2 diabetes mellitus without loss of tactile sensation and foot deformities and 38 nondiabetic individuals in a control group had in-shoe plantar pressures collected. Maximum peak pressure and peak pressure-time integral of each foot were analyzed as separate variables and were masked into 13 areas. Differences in pressure variables were assessed by analysis of covariance, adjusting for relevant covariates at the 95% confidence interval. Results: No significant differences were noted in maximum peak pressures after adjusting for sex, race, age, height, and body mass. However, patients with diabetes mellitus had significantly higher mean ± SD pressure-time integrals at the right whole foot (309.50 ± 144.17 kPa versus 224.06 ± 141.70 kPa, P < .05) and first metatarsal (198.65 ± 138.27 kPa versus 121.54 ± 135.91 kPa, P < .05) masked areas than did those in the control group after adjustment. Conclusions: Patients without clinical observable signs of foot deformity (implying absence of motor neuropathy) and sensory neuropathy had similar in-shoe maximum peak pressures as controls. This finding supported the notion that either component of neuropathy needs to be present before plantar pressures are elevated. Patients with diabetes mellitus demonstrated greater pressure-time integrals, implying that this variable might be the first clinical sign observable even before peripheral neuropathy could be tested.

Abstract Summary: Background: Erythropoietin (Epo) is one of systemic angiogenic factors, and its role in ocular angiogenesis and in diabetic retinopathy (DR) is not yet fully understood. Latest research data reveal possible correlation of higher EPO concentrations of erythropoietin in blood and in the eye, with more severe of stages of DR. The main aim of this work was to examine the possible influence of serum concentrations of erythropoietin on the development and stages of diabetic retinopathy in patients with diabetes mellitus type 2. Methods: The research involved 90 patients examined at University Eye Clinic in Clinical Center of Vojvodina in Novi Sad, Serbia. First group comprised of 60 patients with diabetes mellitus lasting 10 years or more, with diabetic retinopathy. Second, control group, consisted of 30 healthy individuals. In the first group of 60 diabetic patients, 30 of them had non-proliferative diabetic retinopathy (NPDR), and 30 had proliferative diabetic retinopathy (PDR). Laboratory EPO serum levels were determined, and they were correlated to the stage of DR. Concentration of EPO was assessed by ELISA method at the end of the study. Results: The highest average concentration of EPO in serum (9.95 mIU/ml) was determined in group of diabetics with PDR. The lowest average concentration of EPO in serum (6.90 mIU/ml) was found in control group. The average concentration of Epo in serum in group of diabetics with NPDR was 7.00 mIU/ml. EPO concentration in serum was elevated in group of PDR, and it was directly proportional to the level of clinical stadium of PDR, being significantly higher in moderate and severe subgroup of PDR comparing to control healthy subjects, NPDR and mild PDR (h=9.858, p=0.007). Conclusions: Significantly elevated serum concentration of EPO in advanced stages of DR, and positive correlation between EPO serum concentration and clinical stadium of PDR, suggest that erythropoietin presents one of the important growth factors from blood, which plays role in retinal ischemia and angiogenesis in diabetic retinopathy, especially in the proliferative stage of this disease.

Significance. Prevalence of diabetes mellitus (DM) is increasing worldwide. People with diabetes are at higher risk to dry eye syndrome (DES). The increasing dependence of society on computers, air conditioning, and visual workload, etc. results in an increase in the manifestations of DES in diabetic patients. A significant part of the socially active population with diabetes requires prescription of drugs aimed at correcting disorders associated with both hyperglycemia and dry eyes. Conservative treatment of DES in case of diabetes includes prescription of artificial tears, metabolic, immunocorrecting, hormonal, antiallergic therapies as well as treatment of meibomian gland dysfunction (MGD). The tear substitutes, however, cannot always satisfy the needs of doctors and patients due to the imperfections of their formulas. Therefore, more and more new drugs are introduced to the market that require a comprehensive assessment.Purpose. To evaluate the clinical efficacy of Keratrop eye drops – a new artificial tear formulation – in dry eye syndrome treatment in patients with diabetes mellitus (DM).Methods. The study included 65 patients (130 eyes) with dry eye syndrome stages I and II associated with mild and moderate diabetes. These were adult patients of both sexes who had not previously received artificial tears as treatment and were undergoing either inpatient or domiciliary care. All studied patients provided a written informed consent and were divided into 2 groups by random sampling. The main group (35 patients) was receiving Keratrop instillations 2 times a day during 14 days, in the course of antidiabetic treatment. Instillations of “artificial tear” were not prescribed to patients of the control group (30 patients), and they only received antidiabetic treatment prescribed by the endocrinologist. Before and after treatment, all patients underwent standard ophthalmic examinations, meibography imaging, tear film assessment and filled in OSDI questionnaires.Results. The study showed that during treatment, in patients of the experimental group – with both I and II dry eye syndrome stages – a significant decrease in subjective and objective manifestations was observed, along with an improvement in the tear film stability. In the control group, positive dynamics was observed only in patients with the first stage of dry eye syndrome.Conclusion. Dry eye syndrome treatment in patients with diabetes should be comprehensive and must include both basic antidiabetic therapy and instillation of tear substitutes.

Glutathione S-transferases (GSTs) are enzymes that included, in a more range of detoxifying reactions by conjugation of glutathione, to electrophilic material. Polymorphisms n the genes that responsible of GSTs affect, the function of the GSTs. GSTs play an active role in protection of cell against oxidative stress mechanism. Polymorphisms of GSTP1 at codon 105 amino acids forms GSTP1 important site for bind of hydrophobic electrophiles and the substitution of Ile/Val affect substrate specially catalytic activity of the enzyme and may correlate with reach to different diseases in human like diabetes mellitus type2 disease. Correlation between these polymorphisms and changes in the parameters file of diabetic patients has also been found, therefore, the results variation considerably among the studies; therefore, these control study was designed to leading to detecting know, as there are no studies on this performed in the people of Iraq. The polymerase chain reaction-restriction fragment length polymorphism was used to study GSTP1genetic polymorphism in 60 T2DM patients and 50 healthy individuals. Our results showed that presence of the GSTP1 heterozygous mutant allele Ile/Val was more common in subjects with T2DM than in the control group (40.00% and 32.00%, respectively; p = 0.01), as well as the found of the homozygous mutant of GSTP1 allele Val/Val was common in T2DM patient and not found in the control group (3.33% and 0.00%, respectively; p = 0.001).GSTP1 genotypes do not have an effect on blood lipids after infection with diabetes mellitus. Agarose gels used to determined genotypes according to the bands were that appeared in electrophoresis of gel.

Liver damage in diabetes mellitus is of particular interest, since this factor significantly affects the course of the disease, the level of compensation and prognosis of the underlying disease. The aim. To study the effect of complex treatment using ursosan on the functional state of the hepatobiliary system in patients with diabetes mellitus. Materials and methods. The study included 30 patients with type 1 diabetes mellitus and 48 patients with type 2 diabetes. According to the duration of diabetes, patients were divided into three subgroups: a) up to five years; b) 5–10 years; c) more than 10 years. The number of patients was: 1a group – 13, 1b group – 10, 1c group – 7 people; Group 2a – 23, 2b group – 13, 2c group – 10 people. The control group consisted of 23 apparently healthy people. Ursosan was prescribed at a dose of 10-12 mg per 1 kg of body per day for 6 months. Clinical laboratory and instrumental research methods were used to study the functional state of the liver and gallbladder. Research results. After the course of treatment with Ursosan, patients with diabetes mellitus showed normalization of protein, pigment, enzymatic metabolism and, to a lesser extent, lipid metabolism in the liver, which led to an improvement in cellular metabolism and redox processes, providing a stable course of diabetes. Conclusions. A 6-month course of treatment with Ursosan in diabetic patients promotes long-term diabetes compensation. Patients during treatment have a decrease in cytolysis syndrome indicators (alanine aminotransferase (AlAT), aspartate aminotransferase (AsAT), lactate dehydrogenesis (LDH)) by about 1.5 times in all 3 indicators compared to the indicators before treatment. The same trend was observed in terms of gamma-glutamine transferase (GGT) and alkaline phosphatase (ALP)

AbstractBackground and Aims. Previous studies have shown that hypochromia is a common finding in patients with chronic diseases. The aim of our study was to estimate the anthropometric and metabolic characteristics of patients with type 2 diabetes mellitus (T2DM) and hypochromia. Material and Methods. 30 patients with T2DM were recruited for this study. Patient demographics, relevant concomitant illnesses and medical history were recorded. Anthropometric, biochemical parameters (fasting plasma glucose - FPG, glycated hemoglobin -HbA1c, glomerular filtration rate - GFR) and morphology of blood smear were assessed. Patients diagnosed with diabetes and hypochromia constituted the study group and patients with type T2DM but without hypochromia constituted the control group. Results. The study showed no statistically significant differences on anthropometric and metabolic characteristics of patients with diabetes and hypochromia, compared with controls. Conclusions. We observed a high prevalence of hypochromia in diabetic patients (46.66%). Our findings suggest the need of screening for routine hematological tests in patients with T2DM.

Ctla4 Gene

The risk of devolvement of type 1 diabetes mellitus (DM1) remains a challenging problem because neither etiology of the disease nor its prognosis and genetic predisposition to this condition are clearly understood. The development of any autoimmune process starts from the disturbance of subtle molecular mechanisms involved in the regulation of the immune system. Therefore, the genes controlling the function of its major components are at the same time the potential candidate genes encoding for the predisposition to DM1. Their association with the disease was studied by means of comparative analysis of the frequency distribution of alleles and genotypes of the polymorphous rs3087243 (G6230A) marker of the CTLA4 gene encoding for antigen-4 of cytotoxic T-lymphocytes. The present study included 257 patients presenting with type 1 diabetes mellitus and 526 healthy subjects. Genotypes were identified by the "real time" amplification technique. The AA genotype was found to occur less frequently in the diabetic patients than in the control group (11.3% and 22.1% respectively). In contrast, the frequency of the GG genotype was higher in the patients with DM1 than in the healthy subjects (44.7% and 37.5% respectively). It is concluded that the polymorphous rs3087243 marker of the CTLA4 gene is significantly associated with the predisposition to the development of type 1 diabetes mellitus in the patients of Russian descent.

Background: Onset of tuberculosis is high among diabetic mellitus patients in relation to non-diabetic patients. Due to weakened immune system there is a greater risk of tuberculosis seen among type 2 diabetes mellitus patients. As a result, affected patients have difficulty in responding to any kind of treatment when compared to healthy individuals. The objective was to study the clinical and radiological profile of pulmonary tuberculosis among patients having diabetes mellitus (DM).Methods: The study was conducted at the department of pulmonary medicine, in a tertiary health care centre in Eastern India. The study included smear positive pulmonary tuberculosis (PTB) patients with diabetes mellitus and the patients who were smear positive for pulmonary tuberculosis (control group) who met the criteria to participate in the study after a thorough examination. Informed written consent was obtained from all patients before enrolment.Results: A total of 80 patients (15 to 65 years and above) were enrolled in the study with equal numbers being diagnosed with diabetes who had elevated blood sugar values (refer to Table 1). Classical clinical signs were totally correlated with radiography and 57.5% cases showed pulmonary lesions. Among the radiological findings, infiltration was most common in both groups, but more significant in PTB DM group (75 %) followed by cavity (52.5%) in PTB DM group.Conclusions: It can be concluded from the study that in diabetic patients the pattern of pulmonary tuberculosis was significantly different from non-diabetic patients. Pre-treatment bacillary load was high in diabetic patients with pulmonary tuberculosis.

ABSTRACT Aim The objective of this study was to determine the oxidative status of saliva and plasma in diabetic children, by analyzing advanced oxidation protein products (AOPPs) and total antioxidant capacity (TAC). Materials and methods Study included 60 patients with diabetes mellitus type I (DMT1) aged 12.45 ± 2.65 years, and 40 healthy age-matched controls. The AOPP and TAC of the plasma and saliva samples were determined using a commercial QuantiChrom™ Antioxidant Assay Kit (DTAC-100) for TAC determination, and Immunodiagnostic AG [enzyme-linked immunosorbent assay kit for AOPP]. Results Values of salivary and plasma AOPP were lower in diabetic patients than in healthy controls, while value of TAC was clinically and significantly higher in plasma of controls, and clinically higher in saliva of healthy control group, compared with diabetic patients. Average value of hemoglobin A1c (HbA1c) was 7.58 ± 0.85%. Conclusion Results of this study showed that diabetes mellitus as a condition, with well-controlled HbA1c, has no influence on AOPP levels in saliva and plasma, while TAC levels of saliva and plasma are lower in diabetic patients, which means that DMT1 has an influence on the TAC.

Aldosterone To Renin Ratio

Accumulated evidence has shown that low renin hypertension is common in patients with diabetic nephropathy. However, the performance of aldosterone to renin ratio (ARR) in primary aldosteronism (PA) patients with diabetes has not been well validated. Here, we report the performance of screening ARR in PA patients with diabetes. The study enrolled consecutive patients and they underwent ARR testing at screening. Then the diagnosis of PA was confirmed from the Taiwan Primary Aldosteronism Investigation registration dataset. Generalized additive model smoothing plot was used to validate the performance of screening ARR in PA patients with or without diabetes. During this study period, 844 PA patients were confirmed and 136 (16.0%) among them had diabetes. Other 816 patients were diagnosed with essential hypertension and used as the control group and 89 (10.9%) among them had diabetes. PA patients with diabetes were older and had a longer duration of hypertensive latency, higher systolic blood pressure and lower glomerular filtration rate than those PA patients without diabetes. The cut-off value of ARR in the generalized additive model predicting PA was 65 ng/dL per ng/mL/h in diabetic patients, while 45 ng/dL per ng/mL/h in non-diabetic patients. There was a considerable prevalence of diabetes among PA patients, which might be capable of interfering with the conventional screening test. The best cut-off value of ARR, more than 65 ng/dL per ng/mL/h in PA patients with diabetes, was higher than those without diabetes.
