Study to Evaluate Patients With Cerebrotendinous Xanthomatosis (RESTORE)

CTX

The study is made up of two cohorts: a randomized double-blind crossover (placebo withdrawal with rescue) study among patients ≥ 16 years of age (adult cohort) and an open-label dose titration study among pediatric patients ≥1 month and <16 years of age (pediatric cohort)

ScreenPlus: A Comprehensive, Flexible, Multi-disorder Newborn Screening Program

Acid Sphingomyelinase DeficiencyCeroid Lipofuscinosis15 more

ScreenPlus is a consented, multi-disorder pilot newborn screening program implemented in conjunction with the New York State Newborn Screening Program that provides families the option to have their newborn(s) screened for a panel of additional conditions. The study has three primary objectives: 1) define the analytic and clinical validity of multi-tiered screening assays for a flexible panel of disorders, 2) determine disease incidence in an ethnically diverse population, and 3) assess the impact of early diagnosis on health outcomes. Over a five-year period, ScreenPlus aims to screen 175,000 infants born in nine high birthrate, ethnically diverse pilot hospitals in New York for a flexible panel of 14 rare genetic disorders. This study will also involve an evaluation of the Ethical, Legal and Social issues pertaining to NBS for complex disorders, which will be done via online surveys that will be directed towards ScreenPlus parents who opt to participate and qualitative interviews with families of infants who are identified through ScreenPlus.

International Rare Histiocytic Disorders Registry (IRHDR)

Rare Histiocytic Disorders (RHDs)Juvenile Xanthogranuloma (JXG)6 more

The rare histiocytic disorders (RHDs) are characterized by the infiltration of one or more organs by non-LCH histiocytes. They can range from localized disease that resolves spontaneously, to progressive disseminated forms that can be sometimes life-threatening. Since they are extremely rare, there is limited understanding of their causes and best treatment options. Physicians, patients and parents of children with RHDs frequently consult members of the Histiocyte Society regarding the best management of these disorders. Very often, no specific recommendation can be made due to the lack of prospective outcome data, or even large retrospective case series. The creation of an international rare histiocytic disorders registry (IRHDR) could facilitate a uniform diagnosis of the RHDs, as well as the collection and analysis of the clinical, epidemiological, treatment and survival data of patients with RHD. The registry may also lead to future therapeutic recommendations, provide a framework for future clinical trials and create excellent research opportunities.

An Observational Study for Evaluation of for the Prevalence of Cerebrotendinous Xanthomatosis (CTX)...

CTX - Cerebrotendinous Xanthomatosis

The prevalence of CTX in our country is estimated to be 1 / 50.000. The aim of this study is to screen more volunteers by conducting a larger screening from neurology and pediatric metabolism clinics in Turkey. This observational study was designed retrospectively and prospectively in two stages. In the retrospective section, the patient database and / or patient files will be screened in the neurology and pediatric metabolism clinics and the patients aged 40 and below in the neurology clinics with at least two of the following will be enrolled to the study: Ataxia and / or spasticity Bilateral cataract (except senile cataract) Intellectual limitation Non-enhancing hyperintensity on T2 sections in MR imaging of dentate nuclei Autosomal recessive transition pattern. (Ex: Relative Marriage) In the pediatric metabolism centers, cases suspected of CTX and planned to apply the Mignarri Index according to the investigator's opinion will be identified.

Phase II Study of Cholesterol- and Cholestanol-Free Diet, Lovastatin, and Chenodeoxycholic Acid...

Cerebrotendinous Xanthomatosis

OBJECTIVES: I. Assess the biosynthesis of cholesterol and cholestanol, and measure the turnover of individual sterols and bile acids in patients with cerebrotendinous xanthomatosis before and after a cholesterol- and cholestanol-free diet. II. Assess the biosynthesis of cholesterol and cholestanol, and measure the turnover of individual sterols and bile acids in these patients before and after lovastatin and chenodeoxycholic acid.

Cholestanol in Humans

Cerebrotendinous Xanthomatosis

The treatment of cerebrotendinous xanthomatosis an in born error of bile acid synthesis with chenodeoxycholic acid. Patients with this disease over produce cholestanol and bile acid precursors because of the block in synthesis. Replacement with chenodeoxycholic acid shut down abnormal pathway and reduces elevated level of cholestanol and improves the clinical syndrome.

Evaluation of Carotid IMT and Atherogenic Risk Factors in Patients With Cerebrotendinous Xanthomatosis...

Cerebrotendinous Xanthomatosis (CTX)

The aim of the proposed study is to evaluate the risk for cardiovascular disease and 'atherogenic' features of the serum in CTX and to determine preclinical atherosclerosis. The study will include an extensive assessment of lipoprotein profile and carotid artery intima-media thickness (cIMT) measurement. Lipid and lipoprotein profiles will include novel tests such as direct measurements of apolipoprotein A1,B,C2,C3 plasma levels, lipoprotein (a) levels, highly sensitive C-reactive protein levels and PLAC test that measures the levels of lipoprotein-associated phospholipase A2-a vascular-specific inflammatory enzyme implicated in the formation of atherosclerosis

Cerebrotendinous Xanthomatosis (CTX) Prevalence Study

Cerebrotendinous Xanthomatosis (CTX)

This is an observational, multicenter study to determine the prevalence of Cerebrotendinous Xanthomatosis (CTX) in patient populations diagnosed with early-onset idiopathic bilateral cataracts. Patients who are potentially eligible for study participation will be identified through a chart review of patients who were seen at each study site prior to that site's initiation, or by entering care at the site while the site is participating in the trial.
