Filter by:CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access. Visit sanfordresearch.org/CoRDS to enroll.
The objective of this retrospective trial is to assess safety and efficacy of eculizumab in aHUS patients treated outside of an Alexion-sponsored controlled clinical trial.
Protocol is intended to characterize the overall safety and tolerability of eculizumab in this population.
This protocol is intended to formally collect data on the treatment of aHUS with eculizumab in Japanese patients.
The purpose of this study is to investigate the clinical, cognitive outcome and psychosocial outcome of haemolytic uraemic syndrome in childhood. The haemolytic uraemic syndrome (HUS) is the leading cause of acute renal failure in childhood. The more common typical HUS is mostly caused by Shigatoxin-producing enterohaemorrhagic Escherichia coli (EHEC). The rarer atypical HUS is mainly caused by different genetic abnormalities in complement regulatory proteins. About 50 till 60 percent of all patients with HUS develop a severe acute renal failure and require dialysis. Resulting from new diagnostic and therapeutic approaches the survival rate increased during the last years. Despite this, there are only few data concerning long-term prognosis, cognitive and motoric development, as well as psychological coping and health-related quality of life of affected children and their parents.
The investigators examined the outcome of patients with severe Enterohaemorrhagic E. Coli (EHEC) O104:H4 infection suffering from bloody diarrhoea that were at risk to develop hemolytic uremic syndrome and underwent repetitive whole bowl lavage during hospitalization.
Post-marketing safety data on patients treated and untreated with eculizumab or ravulizumab.
There is growing but limited information on the long term clinical status of aHUS patients who have previously received or are continuing to receive treatment with eculizumab. This study is designed to collect clinical data that will provide insight into the long-term outcomes of patients with aHUS.
Thrombotic thrombocytopenia purpura / hemolytic uremic syndrome (TTP/HUS) is a rare, life-threatening disorder. TTP/HUS causes multiple blood clots to form, which prevents blood from reaching the brain and kidneys. TTP/HUS affects 3-5 people per million per year. Anyone can develop TTP/HUS, but it is most common among 30-40 year olds, and women are twice as likely as men to acquire the condition. TTP/HUS sometimes develops as a result of medication use, pregnancy or cancer; however, for the majority of patients (80%) the cause of TTP/HUS is unknown. In 1991, researchers discovered that plasma exchange was superior to plasma infusion in treating idiopathic TTP/HUS. During plasma exchange the patient's blood plasma is removed and replaced with healthy blood plasma. Without plasma exchange, the survival rate for TTP/HUS is extremely low, with fewer than 5% of patients surviving. Treating TTP/HUS with plasma exchange improved the survival rate to 80%. Although this represents a dramatic improvement, researchers are still searching for methods to improve survival. No major advances in treating TTP/HUS have occurred in the past 20 years. Recent research suggests that high-dose plasma exchange may improve the survival of TTP/HUS patients. The investigators will conduct a randomized controlled trial to test whether treating TTP/HUS patients with high-dose versus standard-dose plasma exchange improves the treatment response. The investigators will recruit 150 patients with TTP/HUS from 9 centres across Canada over three years. The investigators will evaluate whether high-dose plasma exchange improves the treatment response, survival, and whether it reduces the number and volume of plasma exchange procedures and duration of hospital stay.
This protocol is designed to collect safety and efficacy data on patients that have been or will be treated with eculizumab for STEC-HUS, in the context of the 2011 STEC-HUS epidemic in Germany.
