Brief summary

The aim of this study is to compare the impact of hypoglycaemia treatment initiated at a blood glucose threshold of 65 mg/dL versus the internationally recommended threshold of 70 mg/dL on 2-hour post-treatment blood glucose levels and the subsequent development of rebound hyperglycaemia in children with type 1 diabetes. The main questions it aims to answer are: Is there a statistically significant difference in 2-hour post-treatment blood glucose levels in children with type 1 diabetes when hypoglycaemia intervention is initiated at a threshold of 70 mg/dL compared to 65 mg/dL?" In children with type 1 diabetes, does the standard hypoglycaemia treatment initiated at the internationally recommended threshold of 70 mg/dL lead to the development of rebound hyperglycaemia (\<180 mg/dL) at the 2nd hour post-treatment? Patients underwent two protocols: intervention at a 65 mg/dl threshold (hospital routine; experimental group) and 70 mg/dl (literature standard; control group). Both protocols utilised 0.3 g/kg of simple carbohydrates, supplemented with a standardised complex carbohydrate (12.8 g) once blood glucose exceeded the target.

Interventions

PROCEDUREthreshold 70 mg/dL

At these levels, children with type 1 diabetes were administered 0.3 g/kg of simple carbohydrates in the form of sugar cubes, and blood glucose was re-evaluated 15 minutes later. According to the ISPAD consensus guidelines, once blood glucose rises above 70 mg/dL following the administration of fast-acting carbohydrates, 10-15 g of complex carbohydrates should be given. As the complex carbohydrate source, the children were provided with four crackers (12.8 g) containing quinoa, black cumin, bran, and oats. Blood glucose levels were measured at 1 and 2 hours post-treatment to monitor for the occurrence of rebound hyperglycaemia.

Inclusion criteria

* A confirmed diagnosis of type 1 diabetes. * Absence of any concurrent chronic illnesses. * Absence of any physiological conditions precluding oral intake. * Absence of significant cognitive or developmental disorders that would impede capacity to participate in the study. * Aged between 7 and 18 years (as children under 7 years of age may experience difficulty consuming whole grain crackers). * Possession of a personal blood glucose monitor. * Absence of persistent hyperglycaemia.

Exclusion criteria

* Days characterised by unusually high levels of routine exercise or physical activity. * The requirement for a second dose of simple carbohydrates (sugar cubes) during a single hypoglycaemia intervention (as consuming two doses may induce hyperglycaemia following the snack). * Experiencing multiple hypoglycaemic episodes within the same day.
