Abstract
Background/aim Increased susceptibility to infections is a serious problem in diabetics. Impairment in the energy metabolism of the immune system is the main source of the problem. Early diagnosis of the impairment in energy metabolism is crucial. Our study aimed to investigate the energy metabolism in leukocytes in patient groups such as prediabetics and patients newly diagnosed with type 2 diabetes mellitus. Materials and methods Our study included 21 newly diagnosed type 2 diabetic patients (NDDP), 30 prediabetic patients, and 22 adult volunteers. 75 g oral glucose tolerance test (OGTT) was applied to all patients included in the study. Blood samples were taken after 9-16 h of fasting and fasting blood glucose (FBG), postprandial blood glucose (PBG) levels, total cholesterol (TC), triglyceride (TG), high- density lipoprotein (HDL), fasting serum insulin, and hemoglobin A1c (HbA1c) levels were evaluated. After the cells were completely lysed, citrate levels from the released mononuclear leukocyte cells (MNC) content were manually studied, and lactate levels were applied to the autoanalyzer with the lactate kit. Lactate and citrate results were calculated as μg/mL. Statistical comparisons were done using Chi-square test, Mann-Whitney U test and student’s t test, and P < 0.05 values were accepted as significant. Results A significant difference was found between the controls and the other groups (newly diagnosed diabetic patients (NDDP), impaired fasting glucose (IFG), and impaired glucose tolerance (IGT)) in terms of FBG levels (P < 0.001, P < 0.001 and P < 0.001, respectively). IFG and IGT patients had significantly higher PBG levels compared to the control group (P = 0.009 and P < 0.001, respectively). There was a significant difference between the IFG and IGT patients in terms of insulin levels (P = 0.019). There was a significant relationship between FBG levels and lactate production only in the NDDP group (r = 0.610, P = 0.003) Conclusion The metabolic effects of hyperglycemia on leukocytes is in direction of anaerobic glycolysis. The increased anaerobic pathway is closely related to blood glucose levels and insulin resistance.

Neutrophil Extracellular Trap Induced Dendritic Cell Activation Leads to Th1 Polarization in Type 1 Diabetes. Front Immunol 2020; 11:661. [PMID: 32346380 PMCID: PMC7172866 DOI: 10.3389/fimmu.2020.00661] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2019] [Accepted: 03/23/2020] [Indexed: 12/23/2022] Open
Abstract
Neutrophils releasing neutrophil extracellular traps (NETs) infiltrate the pancreas prior to type 1 diabetes (T1D) onset; however, the precise nature of their contribution to disease remains poorly defined. To examine how NETs affect immune functions in T1D, we investigated NET composition and their effect on dendritic cells (DCs) and T lymphocytes in T1D children. We showed that T1D patient NET composition differs substantially from that of healthy donors and that the presence of T1D-NETs in a mixed peripheral blood mononuclear cell culture caused a strong shift toward IFNγ-producing T lymphocytes, mediated through activation of innate immunity cells in T1D samples. Importantly, in a monocyte-derived DC (moDC) culture, NETs induced cytokine production, phenotypic change and IFNγ-producing T cells only in samples from T1D patients but not in those from healthy donors. RNA-seq analysis revealed that T1D-NETs presence causes TGFβ downregulation and IFNα upregulation and creates pro-T1D signature in healthy moDCs.

Integrative analysis of the transcriptome profiles observed in type 1, type 2 and gestational diabetes mellitus reveals the role of inflammation. BMC Med Genomics 2014; 7:28.

Abstract
BACKGROUND Type 1 diabetes (T1D) is an autoimmune disease, while type 2 (T2D) and gestational diabetes (GDM) are considered metabolic disturbances. In a previous study evaluating the transcript profiling of peripheral mononuclear blood cells obtained from T1D, T2D and GDM patients we showed that the gene profile of T1D patients was closer to GDM than to T2D. To understand the influence of demographical, clinical, laboratory, pathogenetic and treatment features on the diabetes transcript profiling, we performed an analysis integrating these features with the gene expression profiles of the annotated genes included in databases containing information regarding GWAS and immune cell expression signatures. METHODS Samples from 56 (19 T1D, 20 T2D, and 17 GDM) patients were hybridized to whole genome one-color Agilent 4x44k microarrays. Non-informative genes were filtered by partitioning, and differentially expressed genes were obtained by rank product analysis. Functional analyses were carried out using the DAVID database, and module maps were constructed using the Genomica tool. RESULTS The functional analyses were able to discriminate between T1D and GDM patients based on genes involved in inflammation. Module maps of differentially expressed genes revealed that modulated genes: i) exhibited transcription profiles typical of macrophage and dendritic cells; ii) had been previously associated with diabetic complications by association and by meta-analysis studies, and iii) were influenced by disease duration, obesity, number of gestations, glucose serum levels and the use of medications, such as metformin. CONCLUSION This is the first module map study to show the influence of epidemiological, clinical, laboratory, immunopathogenic and treatment features on the transcription profiles of T1D, T2D and GDM patients.

Abstract
PURPOSE It remains unclear whether perianal abscess is a prediabetes condition or the initial presentation of type 2 diabetes. Using a population-based dataset, this study aimed to explore the risk of type 2 diabetes following perianal abscess. METHODS We used data sourced from the Longitudinal Health Insurance Database 2000. In total, there were 1,419 adult patients with perianal abscess in the study group and 7,095 randomly selected subjects in the comparison group. Stratified Cox proportional hazards regressions were carried out to evaluate the association between being diagnosed with perianal abscess and receiving a subsequent diagnosis of diabetes within 5 years. RESULTS Of the total 8,514 sampled subjects, the incidence rate of diabetes per 100 person-years was 1.87 (95 % confidence interval (CI) = 1.74-2.01); the rate among patients with perianal abscess was 3.00 (95 % CI = 2.60-3.43) and was 1.65 (95 % CI = 1.52-1.79) among comparison patients. Stratified Cox proportional hazards analysis revealed that patients with perianal abscess were more likely to have received a diagnosis of diabetes than comparison patients (hazard ratio = 1.80, 95 % CI = 1.50-2.16, p < 0.001) during the 5-year follow-up period after censoring cases that died from nondiabetes causes and adjusting for patient geographic location, urbanization level, monthly income, hypertension, coronary heart disease, hyperlipidemia, obesity, and alcohol abuse/alcohol dependence syndrome at baseline. CONCLUSIONS Our results suggest that patients with perianal abscess have a higher chance of contracting type 2 diabetes mellitus within the first 5 years following their diagnosis.

Abstract
Obesity is shown to increase the incidence and severity of infectious diseases and
individuals seem to exhibit poor antibody response to vaccination due to several inherent immune defects. With the increasing prevalence of impaired glucose tolerance (IGT) seen in obese individuals, the present study was aimed to investigate the basal immune response and immune response upon Hepatitis B vaccination (HBV) in an obese rat model WNIN/GR-Ob with impaired glucose tolerance (IGT). Decreased proportions of splenic CD4+ T helper cells and CD3+ T cells were observed in obese animals compared to lean animals. Upon HBV, obese animals showed reduced cell-mediated immunity and humoral immunity in terms of splenic lymphocyte proliferative response to Concanavalin A (Con A) and Hepatitis B surface antigen (HBsAg) and HBsAg-specific IgG response. Innate immunity as assessed in terms of Tumor Necrosis Factor α (TNF α) and Nitric oxide (NO) production by peritoneal macrophages upon HBV was low and unchanged, respectively, in obese animals. Thus long-term immunological memory is impaired or altered upon HBV.
