The porphyrias are disorders of haem biosynthesis which present with acute neurovisceral attacks or disorders of sun-exposed skin. Acute attacks occur mainly in adults and comprise severe abdominal pain, nausea, vomiting, autonomic disturbance, central nervous system involvement and peripheral motor neuropathy. Cutaneous porphyrias can be acute or chronic presenting at various ages. Timely diagnosis depends on clinical suspicion leading to referral of appropriate samples for screening by…

Update review of the acute porphyrias

The diagnosis is made by finding increased porphobilinogen excretion in a light‐protected random urine sample, and management includes administration of intravenous human haemin and supportive treatment with non‐porphyrinogenic drugs.

Clinical Guide and Update on Porphyrias.

Physicians should be aware of porphyrias, which could be responsible for unexplained gastrointestinal, neurologic, or skin disorders, and strategies to address dysregulated or dysfunctional steps within the heme biosynthesis pathway are in development.

Challenges in diagnosis and management of acute hepatic porphyrias: from an uncommon pediatric onset to innovative treatments and perspectives

A challenging case study is proposed-with a very unusual pediatric onset of variegate porphyria-as a starting point to summarize the main clinical aspects (namely, clinical manifestations, diagnostic challenges, and therapeutic management) of AHPs, with a focus on the latest therapeutic innovations.

Update on the diagnosis and management of the autosomal dominant acute hepatic porphyrias

Treatment focuses on removing or managing triggers, supportive treatment and suppressing the hepatic haem pathway by administering human haemin in patients with acute neurovisceral attacks.

The clinical importance of early acute hepatic porphyria diagnosis: a national cohort

Previously diagnosed AHP patients have a significantly milder attack course as compared to previously undiagnosed patients, and family screening following sentinel cases might prevent severe AHP attacks.

Porphyria: What Is It and Who Should Be Evaluated?

The porphyrias are a group of rare metabolic disorders, inherited or acquired, along the heme biosynthetic pathway, which could manifest with neurovisceral and/or cutaneous symptoms, depending on the

Variegate Porphyria Triggered by Acute Hepatitis A Infection

Acute hepatitis A infection, and the associated metabolic stress exerted on the haem biosynthetic pathway, induced overt presentation of latent VP and there should be a high index of suspicion for an acute cutaneous porphyria when a photosensitive rash is accompanied by neurovisceral symptoms.

Acute intermittent porphyria: A case report

After acute intermittent porphyria was diagnosed, hemin was administered, which stabilized the patient’s clinical signs and normalized the porphobilinogen.

Acute hepatic porphyria attack following mini gastric bypass surgery

A 32-year-old female who suffered from severe abdominal pain, nausea and general weakness following a bariatric mini gastric bypass surgery and a novel pathogenic mutation in the HMBS gene is reported, which might be an indirect trigger of an acute porphyria attack.

Laboratory Diagnosis of Porphyria

The present review provides an overview of the laboratory assays used most commonly for establishing the diagnosis of porphyria and suggests that laboratory diagnosis based on the measurement of metabolites could be utilized to support clinical suspicion in all symptomatic patients.

Recommendations for the Diagnosis and Treatment of the Acute Porphyrias

The panel, which represents specialties including internal medicine, pediatrics, genetics, gastroenterology, hepatology, and hematology, was charged with formulating updated recommendations for diagnosing and treating the acute porphyrias, issued recommendations based on the specific enzyme and gene defects identified.

Best practice guidelines on clinical management of acute attacks of porphyria and their complications

A small proportion of acute porphyria patients develop recurrent attacks and management options may include gonadotrophin-releasing hormone analogues, ‘prophylactic’ regular haem arginate infusion or ultimately, liver transplantation.

Identifying acute porphyria in patients with acute polyneuropathy or encephalopathy

All hospitals that admit acutely ill patients should be able to provide a validated determination of porphobilinogen within 24 h, and any positive test should be confirmed quantitatively.

A Simple Test for Urinary Porphobilinogen.∗

It is found that the porphobilinogen aldehyde compound as formed in the Ehrlich reaction is wholly insoluble in chloroform, while that of urobilinogen is readily and easily extracted with this solvent.

Analytical Sensitivity and Specificity of Two Screening Methods for Urinary Porphobilinogen

The preliminary assessment of two published screening methods showed that the interpretation of a positive colour in this test could be difficult, and it will be referred to as the ACP method.

CONTROLLED TRIAL OF HAEM ARGINATE IN ACUTE HEPATIC PORPHYRIA

Urinary excretion of porphyrins, porphobilinogen and δ-aminolaevulinic acid following an attack of acute intermittent porphyria

This study highlights the difficulties of using urinary analysis for diagnosing recurrent attacks, and also raises important questions about the pathophysiology of the condition.

Plasma fluorescence scanning and fecal porphyrin analysis for the diagnosis of variegate porphyria: precise determination of sensitivity and specificity with detection of protoporphyrinogen oxidase mutations as a reference standard.

Plasma scanning is a more sensitive and specific test for VP than fecal porphyrin analysis, and neither test is sensitive in children, and both are less sensitive in asymptomatic carriers than in symptomatic cases.

European specialist porphyria laboratories: diagnostic strategies, analytical quality, clinical interpretation, and reporting as assessed by an external quality assurance program.

The findings reinforce the use of EQA schemes as an essential tool to assess both analytical and diagnostic processes and thereby to improve patient care in rare diseases.

Early administration of heme arginate for acute porphyric attacks.

Favorable responses in every attack suggest specific effects of heme therapy should be started immediately on admission in patients with acute attacks.
