Although PN can provide nutritional support for SBS patients, it does not improve the body's own ability to absorb nutrients. PN is associated with serious complications, such as infections, blood clots or liver damage, and the risks increase the longer patients are on PN. Patients on PN often experience poor quality of life with difficulty sleeping, and frequent urination, and patients receiving chronic PN often experience a loss of independence.
Hypoparathyroidism is a rare disorder in which the body produces insufficient levels of parathyroid hormone, the principal regulator of calcium and phosphorus. When the body has too little parathyroid hormone, blood calcium levels drop and phosphorus levels increase, which can cause muscular and neurological symptoms, as well as bone impairments. There is no approved hormone replacement for hypoparathyroidism. It is one of the few remaining hormone deficiency syndromes in which replacement therapy using the native hormone is not clinically available. Hypoparathyroidism is currently managed with large doses of calcium supplementation and active vitamin D therapy to raise the calcium levels in the blood and reduce the severity of symptoms. Over time, calcium may build up in the body and result in serious health risks, including calcifications in the kidneys, heart or brain.
