Growing Up with Type 1 Narcolepsy: Its Anthropometric and Endocrine Features
Virginia Ponziani1, Monia Gennari1, Fabio Pizza2,3
1Pediatric Unit, S. Orsola-Malpighi University Hospital, Bologna, Italy.
Summary
Type 1 narcolepsy (NT1) in youth is linked to rapid weight gain and precocious puberty. Sodium oxybate treatment significantly reduced BMI z-scores in overweight/obese NT1 patients after one year.
Area of Science:
- Pediatric Endocrinology
- Neurology
- Metabolic Disorders
Background:
- Type 1 narcolepsy (NT1) can impact childhood and adolescent development.
- Understanding the anthropometric and endocrine effects of NT1 is crucial for patient management.
Purpose of the Study:
- To assess the effects of NT1 on weight, pubertal development, and growth in children and adolescents.
- To analyze anthropometric and endocrine patterns in treated and untreated NT1 patients.
Main Methods:
- Collected anthropometric, pubertal, metabolic, and endocrine data from 72 NT1 patients at diagnosis.
- Compared baseline data with 1-year follow-up measurements, including those on sodium oxybate treatment.
Main Results:
- High prevalence of overweight (29.2%), obesity (25%), metabolic syndrome (18.8%), and precocious puberty (16.1%) at diagnosis.
- Weight gain was observed soon after NT1 onset; no linear growth alterations were noted.
- Sodium oxybate treatment led to a significant reduction in BMI z-score at 1-year follow-up.
Conclusions:
- NT1 onset in youth is associated with rapid weight gain, obesity, and precocious puberty, without affecting linear growth.
- Sodium oxybate treatment demonstrated significant weight reduction in overweight/obese NT1 patients.

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...

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,...

5.3K
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...

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

01:29The Endocrine System
1.6K
The endocrine system is an extensive network of glands – organs or tissues in the body that create chemicals that control many bodily functions, that secrete hormones, which are chemical messengers that play essential roles in regulating various bodily functions. These hormones are secreted into the bloodstream and travel throughout the body. They require specific receptors to convey signals to cells possessing these corresponding receptors. This complex signaling mechanism ensures that...
