NCT ID: NCT05344599 Recruiting - Clinical trials for Postural Orthostatic Tachycardia Syndrome

Evaluating the Prevalence of Acute Hepatic Porphyria in Postural Tachycardia Syndrome

Start date: January 19, 2022
Phase:
Study type: Observational

Postural Tachycardia Syndrome (POTS) is the most common autonomic disorder and is estimated to affect 3,000,000 individuals in the United States, with 80-85% of patients being women. The condition is characterized by a rapid increase in heart rate (HR) that occurs on standing, and chronic symptoms of cerebral hypoperfusion leading to lightheadedness, dizziness, and blurred vision. The acute hepatic porphyrias(AHP)are among the diseases that present with autonomic cardiovascular(tachycardia)and neurovisceral symptoms (abdominal pain) among others; they present with acute exacerbations Given that there is available treatment for AHP that change the natural progression of the disease, study focuses to investigate the occurrence of AHP in POTS and determine the clinical and neuro-hormonal characteristic of the POTS subgroup that will likely benefit from AHP screening. This study has one visit that involves, answering some questionnaires, coming to the lab for blood work, genetic testing, and some autonomic function tests. About 50 people will take part in this study.

NCT ID: NCT04883905 Recruiting - Clinical trials for Acute Hepatic Porphyria

ELEVATE, a Registry of Patients With Acute Hepatic Porphyria (AHP)

ELEVATE
Start date: April 26, 2021
Phase:
Study type: Observational

This global patient registry is being conducted to characterize the natural history and real-world clinical management of patients with AHP, and to further characterize the real-world safety and effectiveness of givosiran and other approved AHP therapies.
