2004 RESEARCH STUDIES FUNDED
Ranjan Dohil, M.D.
Associate Clinical Professor
Division of Pediatric Gastroenterology and Hepatology
University ofCalifornia,San DiegoLa Jolla, CA
Dr. Dohil was awarded a two year grant by the CRF to study the absorption of cysteamine in the intestinal system. The study is currently winding down. To date, nine control patients and six children with cystinosis have completed the study with no adverse events. The study is going well and the results to date are very promising. The data indicates that the cysteamine is absorbed primarily in the small intestine. With the data collected, the hope is to create a new way of delivering the drug thereby reducing the frequency of taking the medication as well as diminishing the adverse effects of the current medication.
Doris Trauner, M.D.
Professor, Departments of Neurosciences and Pediatrics
Chief, Pediatric Neurology
UCSDSchool of Medicine
La Jolla, CA
Dr. Trauner was awarded a two year grant by the CRF to study myopathy (muscle wasting) in young adults with Cystinosis. Dr. Trauner is hoping to understand why muscle wasting occurs and then determine a treatment regimen that will improve the strength and prevent deterioration in muscle strength. Dr. Trauner initially had difficulty recruiting patients for the study because of concern about the muscle biopsy and about the time required to participate inSan Diego. Dr. Trauner has modified the time required. She currently has nine patients who have volunteered for the study.
Tom Jeitner, Ph.D.
Research Assistant Professor
Department of Biochemistry
Medical College of Wisconsin
Milwaukee,Wisconsin
Dr. Jeitner was awarded a two-year grant to study cysteamine and its analogs to determine whether there are better methods of treatment and drug delivery for Cystinosis patients. Cysteamine is currently being studied as a treatment for Parkinson’s disease and Huntington’s disease.
He has dedicated the majority of his career on the biochemical pharmacology of cysteamine and its analogs. The emphasis of his study is on developing better therapeutics based on the chemical properties of cysteamine. Within the last several months he has identified two parameters for inclusion in the pharmacokinetics study that is aimed at investigating the conversion of cystamine to cysteamine. In the course of this study, he tested a simple compound previously not considered, as a therapeutic for Cystinosis. The result was that the simple compound protected the kidney from deleterious effects of other compounds. This particular finding is being prepared for publication and although not part of the original proposal, is an example of how experiments in one area can lead to the development of better therapies and ideas.
Jess Thoene, M.D.
Director, HaywardGeneticsCenter
Karen Gore Professor of Pediatrics
TulaneUniversity, School ofMedicine
New Orleans, LA
Dr. Thoene has been awarded a one year grant by the CRF to study how lysosomal cystine causes enhanced apoptosis (early programmed cell death). When Dr. Thoene studied apoptosis in cultured Cystinosis skin cells, he found that the presence of lysosomal cystine increases the proportion of cells entering apoptosis by two hundred percent. Over time, this inappropriate commitment to cell death can reduce the number of remaining cells leading to generalized hypocellularity, and the short stature, failure to thrive and most importantly, the kidney disease seen in nephropathic Cystinosis. Dr. Thoene hopes to obtain a better understanding of why apoptosis occurs in patients with Cystinosis.
