Nov 24th, 2021 - the main objective of this study to compare the effects of three diets: carbohydrate count with gluten-free diet, DASH and carbohydrate count with gluten-free diet, and gluten-free diet alone on glycemic control, growth rate, and the quality of li...

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 24th, 2021 - the main objective of this study to compare the effects of three diets: carbohydrate count with gluten-free diet, DASH and carbohydrate count with gluten-free diet, and gluten-free diet alone on glycemic control, growth rate, and the quality of li...

Dec 7th, 2020 - In a group of people with proven acute intermittent porphyria (AIP) mutation, some will remain asymptomatic, while others have repeated periods of porphyria symptoms. Glucose inhibits ALA synthetase (ALAS), the first rate-limiting enzyme in the ha...

Jun 14th, 2018 - The purpose of this study is to evaluate the safety and tolerability of givosiran (ALN-AS1) in AIP patients as well as to characterize pharmacokinetics (PK) and pharmacodynamics (PD) of ALN-AS1 in AIP patients.

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...

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...

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...
