Pathogenesis and treatment of acute intermittent porphyria.

For information on selection criteria, click here. Peripheral cannulas used to administer hematin should be replaced after each use. Aakut above advice applies only to the combined oral contraceptive pill that contains an oestrogen and a progestogen and to oral and depot progestogen-only preparations.

Side effects can be minimized by administering estrogen, preferably by patch. The most frequent presenting symptoms are abdominal pain and tachycardia.

Pathogenesis Two major hypotheses for the pathogenesis of the neurologic lesions that give rise to the clinical features of acute porphyria have been proposed: Determination of PBG in urine. Some individuals, especially those with long-standing repeated attacks, have renal insufficiency without another apparent cause.

Treatment of acute porphyria. Four had pathogenic variants in exon Structure of human porphobilinogen deaminase at 2. The risk to the sibs of the proband depends on the genetic status of the proband’s parents i. Brain magnetic resonance imaging white-matter lesions and cerebrospinal fluid findings in patients with acute intermittent porphyria.

The Application of Clinical Genetics. Reproductive hormones play an important role in the clinical expression of AIP. Combined liver and kidney transplantation, which has been successful, can be considered in those with AIP with repeated severe attacks and renal failure [ Wahlin et al ]. News and articles Systemic messenger RNA as an etiological treatment for acute intermittent porphyria.

Pischik E, Kauppinen R. Full clinical history and examination, including neurologic evaluation if symptomatic. MedGen Related information in MedGen. Symptoms are present in only a minority of those with a genetic change that predisposes to acute intermittent porphyria AIP. Renal transplantation in a case of acute intermittent porphyria. Prevalence In most countries AIP is the most common of the acute hepatic porphyrias [ Anderson et alPuy et al ].

Br J Clin Pharmacol. All individuals with a genetic change in the gene HMBS that predisposes to AIP are at risk of developing acute attacks; however, most never have symptoms and are said to have latent or presymptomatic AIP.

Latent or presymptomatic AIP. Searchable drug safety databases are available at the following websites:.

Evaluation of Relatives at Risk If the HMBS pathogenic variant is known in a family, at-risk relatives can benefit from molecular genetic testing to clarify their genetic status, so that those at increased risk of developing acute attacks of AIP can be identified early and counseled about preventive measures.

Note that a minimum two-fold increase in urinary PBG concentration above the baseline for that individual is consistent with symptoms due to AIP [ Aarsand et al ]; however, in practice, baseline information is rarely available. However, the success of liver transplantation as a cure for recurrent acute attacks [ Soonawalla et al ] and the transplant of a liver from persons with AIP into unaffected persons who then experienced acute attacks [ Dowman et al ] clearly implicate release of a hepatic neurotoxin, probably ALA, as their cause.

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 ]. Otherwise unexplained severe, acute abdominal pain without physical signs see Note.

The course of acute attacks is highly variable within and between individuals. Hot water baths or showers may lessen nausea temporarily, but can present a risk of burns or falls. Seizures may also occur as a manifestation of central nervous system involvement of the acute attack.

It is infused over at least 30 minutes. AIP is inherited in an autosomal dominant manner. Persons in remission often continue to excrete excess PBG in their urine long after symptoms have resolved. To date, five children with homozygous HMBS pathogenic variants have been described. Variants in splice consensus regions flanking each exon are common.
