The minimum effective infusion frequency should be employed, usually a weekly dose of hemin infused via an in-dwelling venous catheter.

Acute intermittent porphyria

Molecular, functional and clinical consequences of some new mutations found in the porphobilinogen deaminase gene. For clarity, excerpts pkrfiri GeneReviews chapters for use in lab reports and clinic notes are a permitted use.

Experience to date suggests that this sort of device carries only a very low, if any, risk of provoking an acute attack. Pischik E, Kauppinen R. Clinical Characteristics Clinical Description Symptoms are present in only a minority of those with a genetic change that predisposes to acute intermittent porphyria AIP.

The initial diagnosis of acute porphyria is confirmed by urinalysis. Good-quality information is now widely available from patient or professional organizations either in paper form intermitant from the Internet; see Resources. The incidence of inherited porphyrias in Europe.

Akut intermittent porfyri (AIP) – Medibas

The most frequent presenting symptoms are abdominal pain and tachycardia. To date, five children with homozygous HMBS pathogenic variants have been described. The color is enhanced by exposure to air and light and reflects increased urinary concentrations of porphyrins and porphobilins formed from the porphyrin precursor porphobilinogen PBG.


Fluid balance and electrolytes. The most common identified triggers for acute attacks are medications, weight loss dietsand surgery. Journal of Clinical Chemistry and Clinical Biochemistry. Onset typically occurs in the third or fourth decade [ Anderson et alElder et al ]. DNA banking is the storage of DNA typically extracted from white blood cells for possible future use. The risk of provoking an acute attack may be highest for women with acute intermittent porphyria, high urinary porphobilinogen PBG levels, or both of these together.

In Sweden the incidence and prevalence of AIP are about four times higher than in Europe due to a founder effect originating in Lappland [ Floderus et al ]. His great-great-great-great-grandson Prince William of Gloucester was reliably diagnosed with variegate porphyria in Some individuals, especially those with long-standing repeated attacks, have renal insufficiency without another apparent cause.

Tests in GTR by Condition.

Reproductive hormones play an important role in the clinical expression of AIP. Acute attacks, which may be provoked by certain drugs, alcoholic beverages, endocrine factors, calorie restriction, stress, and infections, usually resolve within two weeks.

Pathogenesis and treatment of acute intermittent porphyria.

Regional anesthesia, in the form of spinal or epidural anesthesia using bupivacaine, has been safely used. This product is supplied as a dried powder, which must be reconstituted with sterile water immediately before intravenous injection and administered over minutes. Increase mainly indicates in vitro condensation of PBG to uroporphyrins.


However, possible non-medical explanations including alternate paternity or maternity e.

Renal transplantation in a case of acute intermittent porphyria. Combined liver and kidney transplantation in acute intermittent porphyria. In most countries AIP is the most common of the acute hepatic porphyrias [ Anderson et alPuy et al ].

For questions regarding permissions or whether a specified use is allowed, contact: Br J Clin Pharmacol. AIP in Spain is also intremittant heterogeneous disease and two novel mutations have been identified, one of them intermitatnt be particularly prevalent in this area. Clinically indistinguishable acute attacks occur in other acute porphyrias. Back, buttock, or limb pain may be a feature.

Liver transplantation from donors with acute intermittent porphyria. Prevention of secondary complications: Homozygous acute intermittent porphyria in a 7-year-old boy with massive excretions of porphyrins and porphyrin precursors.

GeneReviews Advanced Search Help. The penetrance of overt AIP in France was recently reported as 5. The patients are typically asymptomatic, with most gene carriers having no family history because the condition had remained latent for several generations.

A family history consistent with autosomal dominant inheritance of an acute porphyria; however, is often absent given the low penetrance of clinical manifestations of AIP see Penetrance.

Neurological manifestations of acute intermittent porphyria. Recurrent Acute Attacks Recurrent acute attacks are best managed with support and advice from a porphyria specialist.
