Brief Summary:
This is a phase IV study of 3.5 years duration to evaluate the phenotypic and genetic correlates of diabetes (non-Type 1 in young non-obese Asian Indians in North India and pilot case control study to evaluate the efficacy of sitagliptin (DPP-4 inhibitor) in a sub-group of the study population.

Condition or disease Intervention/treatment Phase
Diabetes Mellitus, Type 2 Drug: Metformin Behavioral: Lifestyle modification Phase 4

Detailed Description:

A phase IV on T2DM with BMI < 25 kg/m2 and age 14-40 years.

Primary Objectives:

  • To investigate phenotype (body composition, anthropometry, pancreatic imaging and endocrine function, insulin resistance, autoantibodies, and other biochemical variables) and genetic (known mutations and polymorphisms) correlates in young (age 14-40 years) diabetic patients (non-type 1).

Secondary Objectives:

  • To study anthropometric and body fat distribution including truncal fat, subcutaneous and intra-abdominal fat in non-obese young patients with diabetes (non-type 1).
  • To study whether insulin secretion, insulin resistance or a combination of both is/are the predominant defect(s) in non-obese young diabetics (non-type 1).
  • To study the prevalence of autoimmunity and/or specific genetic abnormalities in this subgroup of diabetics.
  • To estimate approximate prevalence of diagnostic subcategories based on the sample of population, and profile of complications in each category.
  • To propose rational use of specialized investigations (e.g. GAD65, HNF-1α mutations etc) while investigating a newly diagnosed young diabetic.
  • To determine the rational therapeutic option and prognosis in this sub-population of diabetics based on anthropometric, biochemical, and etiological profiles.
  • Sample size: 205 patients to be enrolled and 120 patients to be enrolled for sub group study
