Active clinical trials for "Wolman Disease"

Cholesteryl Ester Storage Disease (CESD) is an autosomal recessive lysosomal storage disorder (LSD) caused by mutations in the lysosomal acid lipase gene (LIPA) that markedly reduce lysosomal acid lipase (LAL) activity, leading to the accumulation of lipids, predominately cholesteryl esters and triglycerides, in various tissues and cell types. In the liver, accumulation of lipids leads to diffuse microvesicular steatosis, which progresses to fibrosis and ultimately, to micronodular cirrhosis. Patients typically present with hepatomegaly, liver dysfunction, hepatic failure and type II hyperlipidemia. Although hepatosteatosis is a typical finding, the liver biopsy diagnosis may be misclassified as non-alcoholic fatty liver disease, non-alcoholic steatohepatitis or cryptogenic liver disease. Biopsy and radiological findings are not considered diagnostic, but help to suspicion of CESD. The definitive diagnosis is based on deficient LAL activity and/or LIPA gene mutations. CESD is pan-ethnic, however, the disease incidence is unknown. The estimated incidence of the disease indicates that CESD should be largely underdiagnosed especially in European patients. Elevation of serum transaminases, and hepatomegaly are early indications of liver impairment. Therefore, CESD should be considered as a differential diagnosis in liver disease of unknown origin. To data, there is no study which evaluated the frequency of CESD in children with unexplained transaminase elevation and/or organomegaly and/or chronic liver disease. The aim of this prospective, multicenter and cross-sectional study is to investigate frequency of CESD in children with unexplained transaminase elevation and/or and/or chronic liver disease and to identify demographic and clinical features of CESD.

Partners HealthCare maintains a Patient Data Registry (PDR) with information from all patient encounters at Partners HealthCare facilities. We intend to utilize the PDR to identify groups of patient who are of high clinical suspicion for undiagnosed lysosomal acid lipase deficiency. A group of potential participants will be identified through the PDR. Detailed records will be requested to further narrow to ideal participants based upon previously existing diagnoses and symptoms. Participants will be invited to partake in the study via a letter from their Partners care provider with supporting study details. Study participants will be evaluated in a one-time visit. A complete family and medical history will be collected. A physical exam will be performed, and up to 20cc of blood will be drawn. All participants will be notified of their disease status via letter and phone call from the study staff. If the study participant is diagnosed with LALD through this evaluation, proper follow-up recommendations and referrals will be provided. Our intent is to determine if existing patient data can successfully be utilized to aid in the identification of patients with rare genetic disease.

The objective of this study is to determine the frequency of Lysosomal Acid Lipase Deficiency (LAL D) by lysosomal acid lipase (LAL) enzyme activity assay in patients who are considered to be at risk.

The primary outcome of this study is the development of a clinical profile of pediatric patients with LAL-D, which will enable the Sponsor to provide more focused guidance to the medical community as to which pediatric patients should be tested for LAL-D.

Development of a new MS-based biomarker for the early and sensitive diagnosis of Wolman disease blood (plasma)

This is a Natural History study to characterize key aspects of the clinical course of late onset Lysosomal Acid Lipase (LAL) Deficiency/ Cholesteryl Ester Storage Disease (CESD).

Perinatal major depressive disorder affects 20% of women, while perinatal anxiety affects 10% of women. Although pharmacological treatment has shown effectiveness, many pregnant women are concerned about potential adverse effects on the fetus, maternal-infant bonding, and child development.. On the other hand, Depressive disorder in women mainly occurs during the first year after childbirth. It takes many forms according to the onset, severity, and duration of the symptoms including; Postpartum blues (PPB), Postpartum depression (PPD), and Postpartum psychosis (PPP). Lack of access to mental health services during the perinatal period is a significant public health concern that may worse outcome. So, we aimed to study prevalence of women mental health in Assiut governorate and evaluate possible risk factor for it

This is an open-label, multicenter expanded access protocol to allow patients with a confirmed diagnosis of Lysosomal Acid Lipase (LAL) Deficiency in the United States (US), access to sebelipase alfa (recombinant lysosomal acid lipase [rhLAL]) until commercial product is available. Patients enrolled in the expanded access protocol will receive 1 mg/kg intravenous infusions of sebelipase alfa every other week.

Lysosomal Acid Lipase (LAL) deficiency is a rare, autosomal recessive storage disease linked to decrease enzymatic activity of LAL, responsible for intracellular accumulation of cholesterol esters and triglycerides. The accumulation of lipid is in hepatocytes, Kupffer cells and macrophages leading to a fatty liver, hepatic fibrosis that can evolve up to cirrhosis. LAL deficiency is responsible for significant morbidity and early mortality in children, adolescents and adults in connection with a multi visceral disease reaching the liver, gastrointestinal tract and the vascular endothelium. The disease is caused by homozygous or heterozygous mutations in the gene (LIPA chromosome 10q23.2-23.3) which is responsible for the synthesis of the LAL. The disease can be diagnosed by enzymatic analysis using few drops of blood absorbed onto blotting paper . Patients with this deficiency LAL, have no or reduced activity of this enzyme. Because of its rarity, the deficit in LAL is under diagnosed or is diagnosed in patients with liver biological disturbances and / or lipid profile disturbances, steatohepatitis-hepatitis (NASH), the steatosis (NAFLD), the cryptogenic cirrhosis or Wilson disease. Inclusion period of 12 to 18 months (100 patients).
