Panhematin for Prevention of Acute Attacks of Porphyria

Acute Intermittent PorphyriaHereditary Coproporphyria1 more

The purpose of this study is to determine if Panhematin is safe and effective for prevention of acute attacks of porphyria. The study aims to provide high quality evidence for the use on hemin for prevention of acute attacks of porphyria. High quality studies have not been done previously for treating or preventing acute attacks with hemin. The lack of strong evidence for efficacy of hemin for treatment and prevention of attacks limits its availability for patients with acute porphyrias.

Clinical Diagnosis of Acute Porphyria

Hereditary Coproporphyria (HCP)Acute Intermittent Porphyria (AIP)1 more

The purpose of this study is to test whether a focused questionnaire and laboratory tests can better define risk factors associated with possible genetic porphyria. The investigators hypothesize that the genetic carrier state of acute porphyria is distinctive enough that the Genetic Carrier Profile the investigators devise through this study will be useful in identifying carriers of genetic porphyria among the large population with undiagnosed abdominal pain.
