Summary
Insulin hypersensitivity reactions, though rare in type 1 diabetes (T1D) patients, can cause severe symptoms and impact glycemic control. Current treatments offer limited success, highlighting the need for better understanding and new therapies.
Area of Science:
- Immunology
- Endocrinology
- Pediatrics
Background:
- Insulin hypersensitivity reactions (types I, III, IV) are rare but serious complications in type 1 diabetes (T1D) management.
- These reactions can manifest with diverse symptoms, from localized skin reactions to life-threatening anaphylaxis.
Approach:
- The study presents four pediatric cases of insulin hypersensitivity and reviews existing literature.
- Investigated multidisciplinary care involving endocrinology and allergy/immunology.
Key Points:
- Reactions occurred in both newly diagnosed and long-standing T1D patients using injections or pumps.
- Various treatments (antihistamines, immunosuppressants, desensitization) showed minimal improvement.
- One patient required a pancreas transplant due to severe, uncontrollable reactions.
Conclusions:
- Insulin hypersensitivity significantly impacts glycemic control and quality of life in T1D patients.
- Current treatment approaches have limited efficacy.
- Further research into pathophysiology and targeted therapies is crucial.

01:16Insulin: Dosing Regimen and Adverse Effects
184
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

01:22Diabetes Mellitus: Type 2 and Gestational
2.5K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

01:15Hypoglycemia and Glucagon
274
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
