Background:
Diabetic patients with renal disease have increased mortality, largely from cardiovascular disease. This could be related to insulin resistance or to other inherited factors. The aim of the present study was to investigate whether there is evidence of the familial aggregation of increased mortality, even in the absence of diabetes, by studying the reported parental age of death in type 2 diabetes.
Methods:
Patients with type 2 diabetes and nephropathy (group A), patients with type 2 diabetes but without nephropathy (group B) and normal controls (group C) were interviewed and asked to report the age of death of their parents.
Results:
The mean (+/-standard deviation) parental age of death was 68.2 (+/-13.8) years in group A, 67.3 (+/-16.0) years in group B and 68.1 (+/-14.9) years in group C. There was no statistical difference between any of the groups.
Conclusion:
Our preliminary study has failed to show evidence of reduced life expectancy of parents of patients with type 2 diabetes and nephropathy.

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
