The study of Insulin Resistance in the Off Springs of Diabetics and Non Diabetic Patients

Introduction: Insulin resistance is one of the main cause in the pathogenesis of the development of type- 2 diabetes mellitus. Elevated insulin levels and insulin resistance may be present several years prior to the development of hyperglycaemia. Hence the diagnosis of insulin resistance at the initial stages in risk group people could be used as an effective measure to prevent type 2 diabetes mellitus and its outcome, including reduction in morbidity and mortality. Though type 2 diabetes mellitus has multifactorial aetiology, genetic factor plays an important role in the development of diabetes mellitus. So we have tried to establish relation between genetic factor and insulin resistance by studying the insulin resistance in off springs of diabetics and non diabetics patients. Aims and objectives: Estimation of insulin levels in the off springs (non diabetics) of diabetics and non diabetics patients. Comparision of insulin resistance in the off springs (non diabetics) of diabetics and non diabetics. To find the relation between insulin resistance and genetic factor. Material and method: This study was carried out in the department of Biochemistry Grant Government Medical College Mumbai. Total 100 non diabetic people were included in the study of age above 30 years. These are divided into two groups as- Group-I includes 50 off springs (Ist degree relatives) of non diabetic people. Group-II includes 50 off springs (Ist degree relatives) of diabetic people.The fasting plasma glucose and serum insulin levels are estimated in the above two groups. The insulin resistance was calculated by using HOMA-IR model. Result: Fasting plasma glucose, serum insulin level and insulin resistance is significantly increased in group-II people as compared to group-I people. Conclusion: There is a strong relation between genetic factor and insulin resistance which exist prior to the development of diabetes mellitus. The people of group-II are susceptible for the development of diabetes mellitus. If these people are identified and managed early we may prevent or may delay the development of the type 2 diabetes mellitus in these people.
