Nov 26th, 2021 - This is a double-blind, randomized, placebo-controlled, parallel group trial investigating the efficacy and safety of Panhematin™ for preventing acute attacks in at least 20 subjects with well-documented acute porphyria (acute intermittent porphyr...

Nov 2nd, 2021 - The Mendelian inheritance pattern of acute intermittent porphyria, hereditary coproporphyria, and variegate porphyria is autosomal dominant, but the clinical phenotype is heterogeneous. Within the general population, penetrance is low, but among f...

Sep 25th, 2021 - Acute intermittent porphyria is one of eight disorders arising from disturbances in heme biosynthesis where the precursors, 5-aminolevulinate and porphobilinogen, are elevated in plasma and urine. Attacks are characterized by severe abdominal pain...

Sep 16th, 2021 - A partial deficiency of the heme biosynthetic enzyme hydroxymethylbilane synthase (HMBS) leads to acute intermittent porphyria (AIP), a severe neurovisceral, autosomal dominant disorder with low penetrance. Even though in-depth investigations of t...

Aug 11th, 2021 - Porphyrias are a set of rare inherited metabolic disorders, each of them representing a defect in one of the eight enzymes in the haem biosynthetic pathway resulting in the accumulation of organic compounds called porphyrins. Acute hepatic porphyr...

Apr 23rd, 2013 - The British and Irish Porphyria Network guidelines describe best practice in the clinical assessment, investigation and management of acute porphyria attacks and their complications, including severe attacks with neuropathy. Acute attacks of porph...

Nov 26th, 2021 - This is a double-blind, randomized, placebo-controlled, parallel group trial investigating the efficacy and safety of Panhematin™ for preventing acute attacks in at least 20 subjects with well-documented acute porphyria (acute intermittent porphyr...

May 18th, 2021 - Hereditary Tyrosinemia type 1 (HT-1) is a rare genetic disorder in which the newborn child lacks the ability to break down the amino acid tyrosine. As a result of this deficiency, toxic sub-stances build up in the blood and can cause liver failure...

Jan 16th, 2017 - Clinically, both erythropoietic protoporphyria (EPP) and X-linked EPP (XLEPP) are characterized by painful, non-blistering cutaneous photosensitivity with onset in early childhood. EPP is the most common porphyria in children and the third most co...

Dec 18th, 2014 - Acute Intermittent Porphyria (AIP) is inherited as an autosomal dominant disorder of the heme biosynthesis pathway. AIP is caused by a genetic defect in porphobilinogen deaminase (PBGD), a key enzyme for heme synthesis. AIP is characterized by acu...

Apr 17th, 2009 - Heme-oxygenase 1 (HO-1) degrades heme, protects cells against oxidative stress, and is beneficial in several experimental models but has not been pharmacologically activated in humans. The objectives of this study were to evaluate the effects of h...

Nov 7th, 2019 - Pseudoporphyria has a similar presentation to PCT but with no abnormalities in porphyrin metabolism. Risk factors include UV radiation exposure; use of medications such as nonsteroidal anti-inflammatory drugs, diuretics, and retinoids; chronic ren.

Apr 28th, 2019 - The study’s primary endpoint was the average annualized rate of porphyria attacks during 6 months of treatment, which was 3. 2 attacks in 46 patients evaluable for efficacy on givosiran treatment and 12.

Dec 6th, 2017 - NEW YORK (Reuters Health) - Abdominal pain and hyponatremia in a 16-year-old girl with constipation and disordered eating confounded the diagnosis of a much less common condition, acute intermittent porphyria (AIP), according to a case report publ...

Mar 1st, 2016 - Case A 34-year-old woman presented to the ED with severe, persistent abdominal pain that had begun 18 days earlier. She was 7 weeks pregnant and had been seen in the same ED the day before.

Jan 5th, 2012 - January 5, 2012 — A promising gene therapy for hemophilia B that received orphan designation in the European Union in November 2011 received the same status from the US Food and Drug Administration on January 4, 2012, as reported in a press releas...
