This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.
The prevalence of childhood obesity in the United States has more than tripled in the past four decades affecting one in every five adolescent girls and is disproportionally higher among racial and/or ethnic minorities. Normal puberty onset and progression is dependent on normal hypothalamic-pituitary-gonadal (HPG) axis which is affected by whole body metabolism. Gonadotropin-releasing hormone (GnRH) and gonadotropins, LH and FSH, are released in a pulsatile manner for appropriate sex steroids production and gonadal function. Proper pulsatility in the GnRH system is disrupted by a significant change in energy balance such as in obesity. Polycystic Ovary Syndrome (PCOS) is the most common neuroendocrine dysfunction in women of reproductive age. Glucagon-like peptide-1 (GL-1), a peptide hormone secreted by the intestinal enteroendocrine L-cells following glucose and fat intake, stimulates insulin release by the pancreas in response to glucose, decreases gastric emptying and inhibits glucagon secretion. GLP-1 receptors are present in the hypothalamic nuclei and pituitary gland; and it is thought that GLP-1 may directly stimulate GnRH secretion and partially regulate reproduction. In animal studies, GLP-1 was found to stimulate GnRH secretion, to regulate kisspeptin (Kiss-1) mRNA and GnRH mRAN expression. GLP-1 receptor agonists are FDA-approved to treat adults and adolescents with obesity. Although the impact of GLP-1 receptor agonists in reproductive health has been investigated in preclinical trials, and in men with obesity and functional hypogonadism, no studies to date have investigated the impact of GLP-1 receptor agonists in female neuroendocrine function, particularly in youth. The goal of this proposal is to gather critical preliminary data to investigate, in a group of obese adolescent females with PCOS, the impact of GLP-1 agonist administration in addition to lifestyle modifications on the neuroendocrine rhythms - LH frequency and amplitude (principal); body composition, adiposity; and carbohydrate metabolism and insulin sensitivity. To accomplish these aims, we will recruit a cohort of up to 20 adolescents ages 12-18 years, at least 2 years post-menarche, with obesity, PCOS, by NIH criteria, without carbohydrate intolerance and in otherwise good health. Research volunteers will be advised on lifestyle modifications of diet and exercise as per routine, and a GLP-1 agonist will be started according to the product's label as per FDA guidelines in children with obesity. Medication will be titrated to maximal therapeutic dose, as per routine clinical practice. Participants will be treated for a total of 16 weeks. Neuroendocrine rhythms pre- and post-treatment will be compared.
Effects of Glucagon-like Peptide-1 (GLP-1) Agonist in Neuro-reproductive Function in Obese Adolescent Females With Polycystic Ovary Syndrome (PCOS)
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
