What is HPS?
Hermansky-Pudlak Syndrome (HPS) is a rare, multi-system disorder characterized by albinism, visual impairment, platelet dysfunction that results in easy bruising and prolonged bleeding, additional complications include inflammatory bowel disease, kidney disease, and the fatal lung disease: Pulmonary Fibrosis.
Currently there are no FDA approved treatments and HPS has no cure.
What is the “6-minute walk test”?
HPS 6-Minute Walk:
The 6-minute walk test assesses functional capacity in patients with diseases like HPS, which often involves pulmonary fibrosis.
The Test Method: Patients walk back and forth in a corridor (often 100 feet long) for 6 minutes, with rests allowed. It serves as a diagnostic tool, measuring how far someone can walk to evaluate their ability to oxygenate and to monitor for lung disease progression.
Significance: It helps determine if a patient with HPS is a candidate for or needs to remain listed for a lung transplant.
