All patients from the study (ranging in age from 1-20) are alive and well with normal liver function, according to the researchers. Amino acid levels in the study patients stabilized within 6-12 hours of transplant and remained stable since transplant despite unrestricted intake of protein.
MSUD is a metabolic disease which causes amino acids from proteins to accumulate in the body. The disease gets its names from the sweet smell of the urine. The accumulation of amino acids in the blood can cause metabolic crisis at any age, which can lead to brain swelling, stroke and even sudden death. Over a patient's lifetime, chronic instability of blood amino acids can result in serious learning disabilities and mental illness.
Before transplant, the only treatment was strict adherence to a diet almost devoid of protein. Despite adherence to this diet, patients were still at risk of metabolic crisis from something as simple as a common cold, which can disrupt the body's metabolism and cause rapid neurological deterioration.
In 1997, an MSUD patient at another hospital received a liver transplant due to an unrelated medical condition and physicians noticed the symptoms of her MSUD were alleviated.
Based on this serendipitous result, physicians from Children's and the Clinic for Special Children, located in Strasburg, Pa., began working collaboratively to develop a liver transplant protocol for MSUD which optimized patient safety. With a comprehensive, multidisciplinary protocol established, Children's transplant surgeons began performing liver transplants on MSUD patients in May 2004. Children's has performed 18 MSUD liver transplants since then.
