Mortality in Pedigrees with Acute Intermittent Porphyria
Life, 2022 High mortality rates have been reported in historical cohorts of acute intermittent porphyria (AIP) patients. The mortality associated with (hydroxymethylbilane synthase) HMBS variant heterozygosity is unknown. This study estimates all-cause mortality in

Acute hepatic porphyria and hepatocellular carcinoma [PDF]
British Journal of Cancer, 1988 In this study we examined the case histories of 163 living and 82 deceased adult Finnish patients with acute hepatic porphyria. There were 184 patients with acute intermittent porphyria and 61 patients with variegate porphyria. Among the 124 of the 163 living patients, who were traced 1984-1985, no hepatocellular carcinoma was found.

Kidney Involvement in Acute Hepatic Porphyrias: Pathophysiology and Diagnostic Implications
Diagnostics, 2021 Porphyrias are a group of rare disorders originating from an enzyme dysfunction in the pathway of heme biosynthesis. Depending on the specific enzyme involved, porphyrias manifest under drastically different clinical pictures.

Case Report: Lack of Response to Givosiran in a Case of ALAD Porphyria
Frontiers in Genetics, 2022 Introduction: 5-Aminolevulinic acid dehydratase (ALAD) porphyria (ADP) is an autosomal recessive disease characterized by a profound deficiency in ALAD, the second enzyme in the heme biosynthetic pathway, and acute neurovisceral attacks with abdominal ...

Acute Intermittent Porphyria: Flaccid Quadriplegia and Encephalopathy due to Posterior Reversible Encephalopathy Syndrome (PRES) [PDF]
Liaquat National Journal of Primary CareA deficiency of the enzyme HMB Hydroxymethylbilane synthase function, also known as porphobilinogen deaminase, leads to the emergence of acute intermittent porphyria (AIP). AIP is an uncommon form of hepatic porphyria inherited in an autosomal dominant

Biomedicines, 2021 Acute porphyria attacks are associated with the strong up-regulation of hepatic heme synthesis and over-production of neurotoxic heme precursors. First-line therapy is based on carbohydrate loading.

Biochemical and hematological analysis in acute intermittent porphyria (AIP): a case report
Anais da Academia Brasileira de Ciências, 2013 Acute intermittent porphyria is the most common acute porphyria caused by a decrease in hepatic porphobilinogen deaminase activity, resulting in an accumulation of delta-aminolevulinic acid and porphobilinogen.

Mechanisms of Neuronal Damage in Acute Hepatic Porphyrias [PDF]
Diagnostics, 2021 Porphyrias are a group of congenital and acquired diseases caused by an enzymatic impairment in the biosynthesis of heme. Depending on the specific enzyme involved, different types of porphyrias (i.e., chronic vs. acute, cutaneous vs. neurovisceral, hepatic vs. erythropoietic) are described, with different clinical presentations.

Rambam Maimonides Medical Journal, 2023 Objective: In patients with acute hepatic porphyria (AHP), prolonged fasting is a known trigger of AHP attacks. Despite this, some Jewish AHP patients—mainly hereditary coproporphyria (HCP) and variegate porphyria (VP) patients—fast for 25 consecutive ...
