Hereditary thrombotic thrombocytopenic purpura (Upshaw-Schulman syndrome) is a rare disorder characterized by thrombocytopenia as a result of platelet consumption, microangiopathic hemolytic anemia, occlusion of the microvasculature with von Willebrand factor-platelet-thrombic and ischemic end organ damage. The underlying patho-mechanism is a severe congenital ADAMTS13 (a disintegrin and metalloproteinase with thrombospondin type 1 motif, 13) deficiency which is the result of compound heterozygous or homozygous ADAMTS13 gene mutations. Although considered a monogenic disorder the clinical presentation in Upshaw-Schulman syndrome patients varies considerably without an apparent genotype-phenotype correlation. In 2006 we have initiated a registry for patients with Upshaw-Schulman syndrome and their family members to identify possible triggers of acute bouts of TTP, to document individual clinical courses and treatment requirements as well as possible side effects of long standing plasma substitution, e.g. alloantibody formation or viral infections.
Background: - Food allergies are characterized by abnormal immune system responses to certain foods, such as peanuts, strawberries, and shellfish. Some individuals with these allergies have immediate allergic reactions on contact with the food in question and need immediate treatment to prevent severe complications. In contrast, eosinophil-associated gastrointestinal disorders are related disorders in which white blood cells in the intestinal tract react to certain foods, causing abdominal pain, nausea, and other digestion problems. Researchers are interested in studying these conditions to better understand how the immune system responds to food allergies. Objectives: - To examine how the immune system responds to food allergens. - To examine how certain white blood cells contribute to disease in individuals with food allergies and other inflammatory diseases. Eligibility: - Individuals between 18 and 65 years of age who have a history of (a) severe allergic reaction to peanuts (and have peanut-specific antibodies), (b) allergy or inflammatory disease, or (c) eosinophil-associated gastrointestinal disorder (with at least two documented food allergies). - Healthy volunteers between 18 and 65 years of age who have no known allergies or asthma. Design: - All participants will have a screening visit and a procedure visit. The procedure visit will take place within 30 to 60 days of the screening visit, and will take 3 to 4 hours depending on the procedure(s) done. - Participants will be screened with a physical examination and medical history, and will provide blood samples for testing. Participants with peanut or other allergies will have additional tests to determine their levels of sensitivity to certain foods. Participants with eosinophil-associated gastrointestinal disorder will provide stool samples for testing. - At the procedure visit, participants with peanut allergies and participants with other allergies will provide blood samples and have leukapherisis to collect white blood cells for examination. - At the procedure visit, healthy volunteers and participants with eosinophil-associated gastrointestinal disorder will provide blood samples and have leukapherisis to collect white blood cells for examination. In addition, some but not all of these participants will have a procedure called esophagogastroduodenoscopy (EGD), which will examine the esophagus, stomach, and small intestine. Participants who are scheduled to have EGD will be asked to fast for 6 hours before the procedure.
Background: - Autoinflammatory diseases are illnesses that produce episodes of inflammation such as fever, rash, or joint swelling. Some of these diseases can be treated with medications that block the body's reaction to a protein called IL-1, which may be part of the cause of the inflammation. IL-1 blocking agents are very helpful in treating autoinflammatory diseases and have become the standard of care for treatment for some of these diseases. However, more research is needed on related diseases that may be treated with new and currently used IL-1 blocking agents. - XOMA 052 is an experimental drug that is currently being tested as a possible treatment for type 2 diabetes. Initial studies have shown that XOMA 052 neutralizes a specific kind of IL-1, and is also active against certain indicators of inflammation. Researchers are interested in determining whether XOMA 052 can be used to treat autoinflammatory and related diseases. Objectives: - To determine the effectiveness of XOMA 052 as a treatment for inflammation in adults with the autoinflammatory diseases Familial Cold Autoinflammatory Syndrome (FCAS)/Muckle-Wells Syndrome (MWS) and Behcet's Disease. Eligibility: - FCAS/ MWS: Individuals at least 18 years of age who have a known history of the typical disease. - Behcet's Disease: Individuals at least 18 years of age who have evidence of active disease, such as oral or genital ulcers or eye disease. Design: FCAS/MWS Participants - Participants will have an overnight evaluation of their disease, including optional tests (e.g., eye or skin exams). Participants who currently take medications to treat their symptoms will stop taking the medication and will be monitored by study researchers. At the first flare of symptoms, participants will begin to receive XOMA 052. - Participants will have further tests on days 3, 7, and 10 after the initial dose of XOMA 052. If the disease remains under good control, participants will have a clinical exam every 5 days for up to 10 weeks until another disease flare occurs (determined either by symptoms or by inflammation observed in laboratory studies). If the disease is not well controlled with the initial dose of XOMA 052, participants will have additional doses starting at day 7 until either the disease is controlled or researchers determine that the medication is not effective. - Participants will have the option to continue XOMA 052 treatments for up to 1 year. XOMA 052 wil...
Diethylcarbamazine citrate (DEC) treatment of Loa loa infection is complicated by the development of severe adverse reactions that are correlated with the number of circulating microfilariae in the blood. The cause of these reactions is unknown, but they are accompanied by a dramatic interleukin-5 (IL-5)-dependent increase in eosinophilia and evidence of eosinophil activation. This randomized, placebo-controlled, double-blind pilot study (conducted at the NIH Clinical Center) will assess whether and to what extent the administration of reslizumab (Cinquil ), a humanized monoclonal antibody directed against IL-5, given 3 to 7 days before administration of the anthelminthic drug DEC (at 3 mg/kg 3 times daily for 21 days), prevents the development of eosinophilia in 10 adult subjects with Loa loa infection and 0-5000 microfilariae/mL. Secondary outcomes will include the severity of post-treatment effects, markers of eosinophil activation, and effects of reslizumab on microfilarial clearance.
This is a single-center open label study of the IL-1 transfusion protein rilonacept in subjects with Muckle-Wells syndrome (MWS), or Schnitzler syndrome (SchS) in Germany. Prospective subjects will be recruited from a patient population previously characterized in an observational study, and from referrals within the German CAPS community; SchS subjects will be recruited through the Charité Patient pool. The Baseline phase will begin with the Screening visit (day -21 = Visit 1) and continue for three weeks; DHAFs (Daily Health Assessment Forms) will be collected from all subjects from Day - 21 to Day 0. DHAF information including MWAS (Muckle-Wells Activity Score), or SCHAS (Schnitzler Activity Score) values from this period will be used for the baseline phase evaluation. Inclusion to receive rilonacept will occur on day 0 (= Visit 2). On day 0 eligible subjects will receive a loading dose of two subcutaneous (S.C.) injections of rilonacept for a total of 320 mg. Subsequent study drug injections of rilonacept 160 mg will be administered once a week for four weeks. After subjects complete this initial 4-week treatment phase, they will be eligible to receive rilonacept 160 mg once weekly for 48 weeks during the extended treatment phase. DHAFs will be used to assess symptoms throughout the study. Overall a max. of 12 subjects with either MWS or SchS will be enrolled.
To date there are no approved effective therapies for the treatment of cryopyrin-associated periodic syndromes (CAPS) including Familial Cold Autoinflammatory Syndrome (FCAS), Muckle-Wells Syndrome (MWS), or Neonatal Onset Multisystem Inflammatory Disease (NOMID) in Japan. The study will assess the efficacy and safety of canakinumab in Japanese patients with cryopyrin-associated periodic syndromes (CAPS). In previous and currently ongoing CAPS studies (CACZ885A2102, CACZ885D2201, CACZ885D2304, CACZ885D2306), it has been observed that treatment with canakinumab in patients with CAPS contributed to ensure absence of relapse, to improve signs and symptoms and to prevent secondary disease complications. However, no Japanese patients have been included in those studies. This study will allow access for Japanese patients to a new potentially efficacious treatment for CAPS patients with a convenient dosing regimen.
Eosinophilic Esophagitis (EoE) is a chronic inflammatory disease of the esophagus affecting children and adults. The most frequent symptoms are swallowing difficulties and thoracic pain. The disease has first been described in the 1980s and is found with rapidly increasing frequency mainly in industrialized countries. The factors that lead to EoE are until now incompletely understood, of importance, the disease is found more frequently in men and patients suffering from allergic diseases (e.g., Asthma). So far there exists no activity index to define the severity of EoE; such an index is urgently needed for future clinical trials to determine the efficacy of current and future therapies. The investigators' 3-year project, carried out in cooperation with international EoE experts, aims at the development of an activity index for adult and pediatric EoE patients that will be used in future clinical trials as well as observational studies.
