Aims: To evaluate the association of Nuclear factor kappa B1(NFkB1) gene polymorphism with inflammatory markers Urinary Monocyte Chemoattractant Protein 1 (UMCP1) and Tumor Necrosis Factor alfa (TNF alfa) in Patients of diabetes mellitus with or without renal involvement in Eastern India. Material and Methods: Consecutive Patients of Type 2 Diabetes Mellitus (DM) with or without microalbuminuria attending SCB MEDICAL COLLEGE and HOSPITAL Medical OPDs in between September 2018 to September 2019 were recruited in this study. Patients were subjected to blood and urine investigations. DNA extraction and Restriction fragment Length Polymorphism (RFLP) was done in Department of Biochemistry. Controls were unrelated healthy attendants with no history of Diabetes Mellitus, HTN, Chronic Kidney Disease (CKD). Results: Mean Systolic BP, Fasting Blood Glucose, Post Prandial Blood Glucose, HBA1c, Total Cholesterol were significantly higher in diabetes mellitus and diabetic nephropathy groups than control group. Estimated Glomerular Filtration Rate was significantly lower in diabetic nephropathy (p value < 0.001). UMCP1, Urinary Albumin Creatinine Ratio, TNF alfa were higher in diabetes mellitus and nephropathy with p value (<0.001, 0.006 < 0.001) respectively. In between DM and Diabetic Nephropathy groups nfkb1 gene expression, umcp1 and tnf alfa levels were significantly increased in Diabetic nephropathy with p value 0.019, <0.01, 0.001 respectively. Insertion/insertion NFkB1 gene polymorphisms were more in diabetic nephropathy group and were positively correlated with inflammatory markers UMCP1 (r = 0.517, p < 0.01) and TNF alfa (r = 0.172, p = 0.19). Conclusion: insertion/insertion NFkB1 gene polymorphism increases the risk of nephropathy by 2.52 times (OR = 2.52, 95% CI: 0.04 - 0.63, p value = 0.019) in diabetes patients in eastern India.

Insertion/insertion NFkB1 gene polymorphisms were more in diabetic nephropathy group and were positively correlated with inflammatory markers UMCP1 (r = 0.517, p < 0.01) and TNF alfa (r = 0.172, p = 0.19). Conclusion: insertion/insertion NFkB1 gene polymorphism increases the risk of nephropathy by 2.52 times (OR = 2.52, 95% CI: 0.04 - 0.63, p value = 0.019) in diabetes patients in eastern India.","PeriodicalId":51086,"journal":{"name":"Journal of Database Management","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2020-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43524310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introduction: Erectile dysfunction (ED) is a common complication of diabetes mellitus (DM) that is associated with poor quality of life and can be present in type 2 diabetics at the time of diagnosis. There are common risk factors associated with erectile dysfunction in type 2 diabetic subjects. Some of these are potentially treatable or reversible. The risk factors evaluated by this study included glycaemic control, duration of diabetes, obesity, peripheral artery disease (PAD), hypertension and antihypertensive medications use. Materials and Methods: This study was a cross sectional one carried out over a period of six months (June-November, 2016) at the diabetes clinic of the Nnamdi Azikiwe University Teaching Hospital, Nnewi and involved 124 subjects with type 2 diabetes mellitus. A convenience sampling method was used. A detailed physical examination, blood pressure and anthropometric measurements and vascular assessment with a hand-held doppler ultrasound were carried out. Data was collected using a study proforma. Erectile dysfunction was diagnosed with the International Index of Erectile Function questionnaire while anxiety and depression were diagnosed with the Hospital Anxiety and Depression questionnaires. Subjects that had anxiety/depression or hypogonadism were excluded from the study. Results: A total of 124 subjects were studied, 48.4% of whom had erectile dysfunction. Glycaemic control was significantly associated with ED among the subjects (OR = 0.198, 95% CI = 0.081 - 0.483, P 0.05). Conclusion: Poor glycaemic control and presence of PAD significantly increase the risk of ED in male subjects with type 2 DM, thus underscoring the need for an early screening and treatment of these predictors of erectile dysfunction.
