Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study investigated the effects of fat protein counting (CFP) in addition to carbohydrate (CARB) counting for calculating prandial insulin dosage on blood glucose profile in patients with type 1 diabetes (T1D) on basal-bolus insulin therapy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this single center, crossover, randomized, controlled study, control meal (SM: standard meal using carbohydrate counting method) and three test meals (HPM: high protein meal using carbohydrate counting method, HPFM-a: high protein-fat meal using carbohydrate counting method and HPFM-b: high protein-fat meal using carbohydrate and fat-protein counting method) were compared on postprandial early (0-120 minutes), late (120-240 minutes) and total (0-240 minutes) glucose response.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Insulin dose-CARB counting HPM group

HPM (high protein meal), contained 36 g protein,17 g fat, 70 g carbohydrate and 11.5 g fiber, was given to the subjects in breakfast meal (08.30 h) in the hospital. The glycaemic index (GI) of meal was 60.40. The insulin dose for meal was calculated according to the carbohydrate counting (insulin-to-carbohydrate ratio-ICR).Capillary blood glucose values were collected and recorded before (0 min) and every 30 minutes thereafter for 240 minutes.

Group Type EXPERIMENTAL

Calculation of insulin dosages for different meals

Intervention Type OTHER

Calculation of insulin dosages For CARB counting meals using insulin-carbohydrate ratio for dosing mealtime boluses. For fat protein counting meal ICR and additionally fat-protein unit were used for dosing of mealtime boluses.

Insulin dose-CARB counting HPFM group

HPFM (high protein-high fat meal), contained 36 g protein,30 g fat, 70 g carbohydrate and 11.5 g fiber, was given to the subjects in breakfast meal (08.30 h) in the hospital The glycaemic index (GI) of meal was 60.40. The insulin dose for meal was calculated according to the carbohydrate counting (insulin-to-carbohydrate ratio-ICR).Capillary blood glucose values were collected and recorded before (0 min) and every 30 minutes thereafter for 240 minutes.

Insulin dose-CARB+FPU counting-HPFM

HPFM (high protein-high fat meal), contained 36 g protein,30 g fat, 70 g carbohydrate and 11.5 g fiber, was given to the subjects in breakfast meal (08.30 h) in the hospital. The glycaemic index (GI) of meal was 60.40. The insulin dose for meal was calculated according to the carbohydrate counting plus fat-protein counting (insulin-to-carbohydrate ratio-ICR and fat-protein unit-FPU).Capillary blood glucose values were collected and recorded before (0 min) and every 30 minutes thereafter for 240 minutes.

Insulin dose-CARB counting SM group

SM (standart meal), contained 24 g protein,17 g fat, 70 g carbohydrate and 11.5 g fiber, was given to the subjects in breakfast meal (08.30 h) in the hospital. The glycaemic index (GI) of meal was 60.40. The insulin dose for meal was calculated according to the carbohydrate counting (insulin-to-carbohydrate ratio-ICR and fat-protein unit-FPU).Capillary blood glucose values were collected and recorded before (0 min) and every 30 minutes thereafter for 240 minutes.
