Brief Summary
Type 1 diabetes is an autoimmune disorder characterized by beta cell destruction resulting in insulinopenia. Currently it is being treated with insulin. Dipeptidylpeptidase inhibitors (DPP4 inhibitors e.g. linagliptin \& sitagliptin) has been used for type 2 diabetes mellitus (T2DM) traditionally. Previous studies has shown that it is also effective in type 1 diabetes mellitus (T1DM), but the mechanism of action not well understood. This study will evaluate possible mechanism of action of linagliptin in T1DM patients.

Outcome Measures
Primary Outcomes (3)
Effect of Linagliptin on HbA1c in T1DM patients
Change in HbA1C in linagliptin group as compared to placebo group
After 3 months of the starting of the treatment
Effect of Linagliptin on glycemic variability in T1DM patients
Change in glycemic variability (CGMS indices) in linagliptin group as compared to placebo group
After 3 months of the starting of the treatment
Effect of Linagliptin on insulin requirement in T1DM patients
Change in insulin requirement in linagliptin group as compared to placebo group
After 3 months of the starting of the treatment
Secondary Outcomes (2)
Effect of linagliptin on GLP1 level during mixed meal test in T1DM patients
after 3 months of the starting of the treatment
Effect of linagliptin on glucagon level during mixed meal test in T1DM patients
after 3 months of the starting of the treatment
Study Arms (2)
Linagliptin treatment group
ACTIVE COMPARATORGroup will receive linagliptin ( 5 mg / day ) for 3 months in addition to their insulin
Placebo group
PLACEBO COMPARATORGroup will receive placebo for 3 months in addition to their insulin
Interventions
Baseline HbA1C will be assessed. Before starting treatment with linagliptin or placebo Mixed meal test will be conducted with the standard protocol. Morning dose of insulin to be omitted on the day of mixed meal test. During the mixed meal test glucose, C-peptide, GLP1 and glucagon will be measured at 0, 30, 60, 120, 180 minutes. 72 hour blood glucose profile to be monitored with continuous glucose monitoring system (CGMS). Markers of glucose control and glucose variability will be measured. Then we will randomly divide these patients in two group (linagliptin and placebo group). After 3 month period 72 hour blood glucose profile, HbA1C and Mixed meal test will be repeated to document any change in blood glucose profile.

Eligibility Criteria
You may qualify if:
- Male or female adult, aged 15 to 30 years
- Duration of type 1 Diabetes Mellitus for 6 months or more, as established by medical history
- Current treatment with multiple injections of insulin for at least 3 months prior to screening visit; and using the same insulin during the last 1 month
- HbA1c \< 8%
- Body mass index (BMI) \< 25 kg/mt2
- Euthyroid patient. If thyroid dysfunction is present then thyroid function test (TFT) should be normal at the time of study ( with medication)
You may not qualify if:
- On pramlintide, metformin, GLP1 agonist or DPP4 inhibitor. If taking this drugs then stop them 2 wk prior to study.
- On prokinetics \& proton pump inhibitor (PPI). If taking this drugs then stop them 2 wk prior to study
- Creatinine of \>1.5 mg/dl or a calculated creatinin clearance of \<50 ml/min or overt proteinuria.
- Fasting blood glucose (FBG) \< 72 or \> 180 in the day of mixed meal test (MMT)
- Pregnant
- Seriously ill patients
- Presence of gastroparesis ( if history is suggestive of autonomic neuropathy or gastroparesis then gastric emptying study to be done to rule it out)
- Type 1 Diabetes Mellitus for less than 6 months duration
- Presence of celiac disease
