Filter by:Rare skin diseases are generally defined as serious life-threatening, progressive chronic diseases of the skin that occur extremely rarely (i.e., 5 in 10,000 people are affected). More than 80% are hereditary. In most cases, late diagnosis and the lack of therapeutic strategies also contribute to severe disease progression. Therefore, new therapeutic options are urgently needed and with them knowledge of the underlying mechanisms of disease development. The aim of this project is to better understand disease mechanisms and to identify new pathways and drug targets that will improve patient care or therapy. In order to investigate the mechanisms of disease development, it is necessary to isolate biological material, i.e. blood and affected skin tissue from patients. For this purpose, adults 18 years of age and older with a congenital rare skin disease are included. We take blood and (lesional) skin biopsies from patients to perform immunoprofiling, as well as cell biological studies with the patient's cells. The risk for the patients is low, as only peripheral blood and skin biopsies are taken. Potential risks include bruising and pain as well as infection, postoperative bleeding, wound infection or delayed wound healing, pain, and scarring. The samples are pseudonymized and stored with the pseudonym only. Cells and skin samples are only preserved with the prior consent of the patient.
The purpose of this study is to form a chronological map of common diseases and rare diseases in Chinese population by determining the prevalence of different diseases in each age group.
This is an international, multicenter study with two components: Registry - A standardized genetic screening and a prospective, standardized, cross-sectional clinical data collection - Enrollment is open to all genes on the RD Rare Gene List Natural History Study - A prospective, standardized, longitudinal Natural History Study - Enrollment opens gene-by-gene, based on funding and within-gene Registry enrollment The study objectives are as follows. Registry Objectives 1. Genotype Characterization 2. Cross-Sectional Phenotype Characterization (within gene) 3. Establish a Link to My Retina Tracker Registry (MRTR) 4. Ancillary Exploratory Studies - Pooling of Genes Natural History Study Objectives 1. Natural History (within gene) 2. Structure-Function Relationship (within gene) 3. Risk Factors for Progression (within gene) 4. Ancillary Exploratory Studies - Pooling of Genes
Next generation sequencing (NGS) allows some better diagnostic results, particularly, in the rare diseases field. At a twenty five percent rate, those exams highlight some variants which are not yet described in human pathology. The relationship between a variant found inside a candidate gene and a pathology, is able to be confirmed by functional studies at a protein level. This study aims to build a biological collection to feed further functional studies to confirm the relationship between NGS identified variants, and the clinical signs and symptoms.
Prospective, multi-site, non-randomized (single arm) study to evaluate the feasibility, the yield and clinical utility of trio WGS in 30 critically ill patients in neonatology intensive care units (NICU) and pediatric intensive care units (PICU) in Belgium. Results are expected to be returned within 7 days after receipt of blood samples in the laboratory. Primary outcome will be evaluated after clinical interpretation, whereas secondary outcome will be evaluated from the clinical utility survey to be completed by clinical geneticists.
The purpose of this registry is to collect retrospective and prospective standardized data of patients treated with particle therapy, either with protons or carbon ions, at the National Center for Oncological Hadrontherapy (CNAO) based in Pavia. By keeping track of the patients treated, it will allow the investigators to periodically analyze and evaluate data collected of daily clinical activity. This will help gathering more information on the results of particle therapy and will provide the basis for in depth evaluation of patients' outcome with respect to the delivered treatment.
Tuberous sclerosis complex (TSC), affecting 1 in 6.000 live births, is characterized by the development of multisystem tumors. Seizures are frequent up to 80% of individuals. They usually start in infancy and are often drug resistant, with a high risk of intellectual disability and autism spectrum disorders. In animal models, preventive treatment before seizures onset significantly decreased the risk of epilepsy as well as associated comorbidities. EPISTOP randomized clinical trial (RCT) aimed to validate the effect of preventive therapy in patients with TSC diagnosed before clinical seizures with abnormal EEG, versus late standard therapy of epilepsy, administered after the seizures onset. This preventive therapy resulted in a significant better outcome in seizures and co-morbidities. However, this trial included few patients and did not allow to fully explore the secondary endpoints. Our goal within EPISTOP-IDEAL project is to benefit from joining clinical expertise of EPISTOP project and experts from IDEAL EU project on methodologies for CTs in small populations in order to consolidate the results of EPISTOP CT using uncertainty evaluation of the existing data of randomized and observational arms and adding important information from external data collected after EPISTOP ended. This collaboration aims to an optimal use of all available data (RCT, observational and external data collected with the same protocol). The goal is to demonstrate the added value of these methodologies in TSC CT and to their further use to rare epilepsies, and other rare diseases.
The SRDR is a national registry that records rare diseases in people of any age who live in Switzerland. It serves as a platform for scientists, health professionals, affected people, and politicians.The SRDR aims to collect epidemiological data on rare diseases, and data on changes to the diagnosis over time. The SRDR will further serve as a research platform and facilitate patient participation in national and international studies. The SRDR will promote harmonization of data and method between the numerous existing disease-specific registries in Switzerland, will strengthen the exchange with international rare disease registries for research and policy, and will build a network for communication for patients and health care providers.
Despite rapidly advancing developments in targeted therapeutics and genetic sequencing, persistent limits in the accuracy and throughput of clinical phenotyping has led to a widening gap between the potential and the actual benefits realized by precision medicine. Recent advances in machine learning and image processing techniques have shown that machine learning models can identify features unrecognized by human experts and more precisely/accurately assess common measurements made in clinical practice. The investigators have developed an algorithm, termed EchoNet-LVH, to identify cardiac hypertrophy and identify patients who would benefit from additional screening for cardiac amyloidosis and will prospectively evaluate its accuracy in identifying patients whom would benefit from additional screening for cardiac amyloidosis.
During the last decades hematologists have excelled at improving and refining the classification, diagnosis, and thus ultimately the therapeutic decision-making process for their patients. This continuous evolution proceeded in parallel to seminal discoveries in basic science such as FISH, PCR and NGS. So far, the current WHO classification serves as reference to diagnostic decision making and is largely based on 5 diagnostic pillars: cytomorphology of peripheral blood and/or bone marrow smears, histology and immunohistochemistry of bone marrow trephine biopsies or lymph nodes, immunophenotyping, chromosome banding analysis supplemented by FISH analysis, molecular genetics including PCR and targeted panel sequencing via NGS. This leads to a swift diagnosis in 90 % of all cases. The leftover 10 % remain a challenge for hematopathologists and clinicians alike and are resolved through interdisciplinary teams in the context of specialized boards. With the advent of high throughput sequencing (mainly WGS and WTS) the possibility of a comprehensive and detailed portrait of the genetic alterations - specifically in challenging cases - has become a realistic alternative to classical methods. In SIRIUS the investigators will prospectively challenge this hypothesis to address the question of how often a better or final diagnosis can be delivered by WGS and/or WTS and if unclear cases can be efficiently resolved.
