May 20, 2020 COVID-19 UPDATE Multisystem Inflammatory Syndrome in Children (MIS-C) Info Sheet: MIS-C is a rare and potentially fatal inflammatory disease in children that is linked to COVID-19, even in those who have been asymptomatic for COVID-19. Treatment may include steroids, which should be used with extreme caution in UCD. Steroids cause excessive ammonia production that could lead to hyperammonemia. Learn about the signs and symptoms of MIS-C and, if your UCD child shows signs, alert medical personnel that steroids may be contraindicated.

October 24, 2019 UREA CYCLE DISORDERS RESEARCH CONSORTIUM RECEIVES NEW 5-YEAR FUNDING:National Institutes of Health Rare Diseases Clinical Research Network has awarded the Urea Cycle Disorders Consortium (UCDC) $5 million funding to continue research for urea cycle disorders. Founded in 2003 by UCD clinical research experts and the National Urea Cycle Disorders Foundation (NUCDF), the UCDC was established and received its first 5-year funding as one of ten consortia to study rare diseases by the Office of Rare Disease Research.
Now co-led by principal investigators Dr. Andrea Gropman at Children's National Medical Center, Dr. Sandesh Nagamani at Baylor, and Cynthia Le Mons at NUCDF, the17-site international UCD Consortium of physicians, scientists, neuropsychologists, nurses, genetic counselors and researchers will continue to work in collaboration with UCD patients and families to conduct studies to improve the understanding of UCDs, long-term health outcomes, and accelerate the development of new treatments.
"It's gratifying that patients diagnosed with urea cycle disorder now are surviving, growing up, becoming young adults and starting families themselves. Twenty to 30 years ago, this never would have seemed conceivable," Dr. Gropman says. "We have collected many years of longitudinal clinical data, but with this new funding we can address critical questions about UCD that are meaningful on a day-to-day basis for UCD patients and families and improve long-term health and quality of life."
