Active clinical trials for "Kallmann Syndrome"

This study will evaluate the efficacy and safety of long term use of hCG alone or hCG plus hMG in the treatment of male patients with isolated hypogonadotropic hypogonadism (IHH). One third of the participants will receive hCG treatment alone and the other third of the participants will receive hCG treatment alone for six months, then the hMG will be added. And the last third of the participants will receive hCG and hMG treatment since the beginning of the treatment.

Objective is to characterize epidemiology, clinical and genetic features of Kallmann syndrome in Finland.

The goal of this study is to learn about the role of kisspeptin in the reproductive system. Kisspeptin is a naturally occurring hormone in humans that causes the release of other hormones, including gonadotropin-releasing hormone (GnRH) in the body.

The goal of this study is to learn more about the genes that control puberty and reproduction in humans.

Introduction Rare complex syndromes Patients with complex genetic syndromes, by definition, have combined medical problems affecting multiple organ systems, and intellectual disability is often part of the syndrome. During childhood, patients with rare genetic syndromes receive multidisciplinary and specialized medical care; they usually receive medical care from 3-4 medical specialists. Increased life expectancy Although many genetic syndromes used to cause premature death, improvement of medical care has improved life expectancy. More and more patients are now reaching adult age, and the complexity of the syndrome persists into adulthood. However, until recently, multidisciplinary care was not available for adults with rare genetic syndromes. Ideally, active and well-coordinated health management is provided to prevent, detect, and treat comorbidities that are part of the syndrome. However, after transition from pediatric to adult medical care, patients and their parents often report fragmented poor quality care instead of adequate and integrated health management. Therefore, pediatricians express the urgent need for adequate, multidisciplinary adult follow up of their pediatric patients with rare genetic syndromes. Medical guidelines for adults not exist and the literature on health problems in these adults is scarce. Although there is a clear explanation for the absence of adult guidelines (i.e. the fact that in the past patients with rare genetic syndromes often died before reaching adult age), there is an urgent need for an overview of medical issues at adult age, for 'best practice' and, if possible, for medical guidelines. The aim of this study is to get an overview of medical needs of adults with rare genetic syndromes, including: comorbidities medical and their impact on quality of life medication use the need for adaption of medication dose according to each syndrome Methods and Results This is a retrospective file study. Analysis will be performed using SPSS version 23 and R version 3.6.0.

The purpose of this study is to explore the genetic basis of reproductive disorders and cleft lip and/or palate.

Men with idiopathic hypogonadotropic hypogonadism (IHH, Kallmann Syndrome) may have small testicular size, low testosterone levels, no history of puberty, and infertility. These men lack a hormone called gonadotropin releasing hormone (GnRH) that stimulates the development and maturation of the testes. This study will investigate the impact of hormonal treatments on men with IHH. The goal of hormonal therapy is to maximize the potential fertility in these individuals.

The traditional therapy for induction of spermatogenesis in male hypogonadotropic hypogonadism requires both HCG and human menopausal gonadotropin (HMG) or FSH until pregnancy occurs. Because of the high cost of hMG or FSH preparations and poor compliance, the investigators raise a new sequential therapeutic approach which can make the treatment more economic and tolerable. The zinc supplement will be also evaluated in patients in this study. This randomized, parallel, open, and multi-center study will compare the efficacy of traditional therapy with new therapy and evaluate the safety of the new protocol.

Technologic advances (i.e. next generation sequencing technologies and novel bioinformatics approaches) have been drivers of scientific discovery and have deepened our understanding of the genetics and genomics of health and disease. In parallel, the falling cost of sequencing has led to screening moving from specialty clinics into the primary care setting. However, our ability to help patients and families understand these technologies and related genetic health literacy issues lag behind. These factors pose a number of questions and challenges for clinicians including: how can we best present complex genetic/genomic information to patients to ensure that patients understand the information and can make informed decisions? What are the specific information and support needs of patients and families to be able to make decisions that are in line with their values? In collaboration with investigators from the Harvard Reproductive Endocrine Sciences Center at the Massachusetts General Hospital, this project broadly aims to examine patient understanding and factors affecting decisions surrounding genetic testing. Using the paradigm of a rare genetic disorder (isolated gonadotropin releasing hormone [GnRH] deficiency - hypogonadotropic hypogonadism/Kallmann syndrome [HH/KS]) we will examine the views and perspectives of patients and healthcare professionals alike regarding genetic/genomic information and testing with the intention of identifying patient-centered responses to these unmet needs and challenges.

The investigators are doing this research study to look at the relationship between testosterone (the main sex hormone in men) and insulin (the hormone that controls blood sugar levels) in men with Idiopathic Hypogonadotropic Hypogonadism (IHH). The investigators hypothesize that normalizing testosterone levels in men with IHH enhances insulin sensitivity, reduces visceral fat, increases lean body mass, and improves the lipid profile.
