2 Clinical Trials for Various Conditions
The hyper IgD syndrome (HIDS) is an inflammatory disease caused by mevalonate kinase deficiency. There is no cure, and available treatments of HIDS febrile episodes have shown limited clinical efficacy. The development of effective interventions for HIDS is limited by our poor understanding of the disease. The goal of the study is to better characterize the inflammatory response during HIDS episodes and to determine the relationship between this response and blood and urine markers of mevalonate kinase deficiency. This knowledge will help us learn more about the cause of the disease and should lead to the identification of new disease biomarkers that can be used to evaluate clinical efficacy in future therapeutic trials. The primary hypothesis is that the costimulatory B7 glycoprotein abnormalities identified in the murine MKD model will be recapitulated in sera obtained from human HIDS patients, either before, during or after febrile episodes. The secondary hypothesis is that B7 glycoprotein molecule levels will correlate with clinical symptomatic severity score, other known biomarkers of HIDS, markers of inflammation and or markers of isoprenoid metabolism.
Participants wanted for study of mevalonate kinase deficiency (MKD), mevalonic aciduria, or hyperimmunoglobulinemia with periodic fever syndrome (HIDS). Patients with MKD (mevalonic aciduria or hyperimmunoglobulinemia with periodic fever syndrome (HIDS)) may be eligible for a research study conducted at Oregon Health \& Science University (OHSU) in Portland, Oregon USA. The purpose of the study is to find out more about how these diseases affect body chemistry and health. The researchers also want to find out how cholesterol in the diet affect blood cholesterol and how the body handles cholesterol. This is a short-term and long-term dietary study. The long-term goal of this research is to see if controlling dietary cholesterol can decrease any of the symptoms of the diseases. The study could involve up to 12 one-week admissions to OHSU over the course of 5 years.
