Brief Summary

To compare the effects of different initial insulin dose regimens during the short-term insulin intensive treatment on time to glycemic goal, hypoglycemia prevalence, glycemic variability and other safety problems in newly diagnosed type 2 diabetes mellitus(T2DM) patients, in order to investigate the rational of formula based initiation regimen.

Detailed Description

Diabetes has become one of the major chronic non-communicable diseases. Its prevalence was rising in these years. Short-term intensive insulin therapy can improve the β-cell function and nearly half of the patients can live with long-term glycemic remission. It has therefore become the recommended treatment for the newly diagnosis T2DM patients with high blood glucose. However, due to the glycemic goal for intensive therapy is strict, it's important to find out a suitable initial insulin regimen for continuous subcutaneous insulin infusion(CSII) with which patients can achieve euglycemia safely, stably and rapidly. In previous study, the investigators found out that the total daily insulin dose at the first day when euglycemia was achieved（TDD-1） was associated with weight, waist circumference, triglycerides and fasting blood glucose levels. According to this, the investigators figured out a formula for estimation of insulin dose for the short-term intensive insulin therapy in patients with newly diagnosed T2DM. However, its feasibility needs to be further verified. Therefore, the investigators conducted this prospective randomized controlled study to compare the effects of different initial insulin dose regimens during the short-term insulin intensive treatment on time to glycemic goal, hypoglycemia prevalence, glycemic variability and other safety problems in newly diagnosed type 2 diabetes patients, in order to investigate the rational of formula based initiation regimen.

Study Groups

Formula-based

Initial insulin regimen was decided according to the formula developed by the investigators previously.

Group Type: EXPERIMENTAL

CSII with formula-based initial insulin regimen

Intervention Type: DRUG

Initial total daily insulin dose(TDD) for CSII was calculated with a formula :（estimate TDD-1(eTDD-1) = 0.35× body weight (kg) + 2.05× FPG (mmol/L) + 4.24×triglyceride(mmol/L) + 0.55× waist circumference (cm) - 49.1）, 42% of which was assigned as total basal dose and 58% as total premeal dose, with the pre-meal doses divided into 30:35:35 for breakfast, lunch and dinner.

Weight-based

Initial insulin regimen was decided according to current guidelines.

Group Type: PLACEBO_COMPARATOR

CSII with weight-based initial insulin regimen

Intervention Type: DRUG

TDD for CSII was started with 0.5 IU/kg, 50% of which was assigned as total basal dose and 50% as total premeal dose, and the total pre-meal dose was divided equally before each meal.

Interventions

CSII with formula-based initial insulin regimen

Initial total daily insulin dose(TDD) for CSII was calculated with a formula :（estimate TDD-1(eTDD-1) = 0.35× body weight (kg) + 2.05× FPG (mmol/L) + 4.24×triglyceride(mmol/L) + 0.55× waist circumference (cm) - 49.1）, 42% of which was assigned as total basal dose and 58% as total premeal dose, with the pre-meal doses divided into 30:35:35 for breakfast, lunch and dinner.

Intervention Type: DRUG

CSII with weight-based initial insulin regimen

TDD for CSII was started with 0.5 IU/kg, 50% of which was assigned as total basal dose and 50% as total premeal dose, and the total pre-meal dose was divided equally before each meal.

Intervention Type: DRUG

Exclusion Criteria

• Type 1 diabetes or special type of diabetes;
• Acute complications of diabetes: ketoacidosis, hyperosmolar coma, lactic acidosis, etc.;
• Severe macrovascular complications: acute cerebral vascular accidents, acute coronary syndromes, peripheral arterial disease requiring vascular intervention or amputees for hospitalization occur within 12 months before selection;
• Severe microvascular complications: proliferative phase retinopathy; urinary albumin excretion rate(AER)> 300 mg/g or urinary protein Positive, quantitative> 0.5 g/d; uncontrolled painful diabetic neuropathy and significant diabetic autonomic neuropathy;
