How is AIP diagnosed?
What is AIP diagnosis? General Discussion. Summary. Acute intermittent porphyria (AIP) is a rare metabolic disorder that is characterized by partial deficiency of the enzyme hydroxymethylbilane synthase (also known as porphobilinogen deaminase).
What is the cause of AIP?
With acute intermittent porphyria (AIP), an accurate, timely diagnosis is critical. Delayed treatment can result in neurological damage or even death. AIP should be considered in any patient with …
What are the signs and symptoms of AIP?
Jun 03, 2019 · Acute intermittent porphyria is known as AIP. It is a very erratic autosomal dominant metabolic disorder which affects the production of heme, a iron-containing compound, due to the lack of porphobilinogen deaminase. Acute Intermittent Porphyria is caused by inheriting a defected gene from one or both of the parents.
Is AIP a multifactorial disorder?
As the name suggests, autoimmune pancreatitis (AIP) is a chronic condition of pancreatitis caused by autoimmune condition. In this condition, the immune system attacks the tissues of pancreas. This form of chronic pancreatitis responds to steroid therapy in controlling the symptoms. There are two types of AIP – Type 1 (IgG4-related pancreatitis) and Type 2.
What are the symptoms of AIP?
- Psychological symptoms such as feeling anxious, confused, or depressed.
- Muscle weakness.
- Fast heart rate.
- Pain in the arms, legs, chest, neck, or head.
- High blood pressure.
- Nausea or vomiting.
- Pain in the abdomen.
- Constipation.

What does porphyria pain feel like?
Severe abdominal pain is the most common symptom of acute porphyrias. Pain in other parts of the body, such as the chest, legs, or back, also may occur. Patients with acute porphyrias may experience muscle pain, sometimes accompanied by tingling, numbness, weakness, or paralysis.Apr 6, 2021

Diagnosing and Managing AIP
With acute intermittent porphyria (AIP), an accurate, timely diagnosis is critical. Delayed treatment can result in neurological damage or even death. AIP should be considered in any patient with symptoms that are prominent for AIP, particularly abdominal pain, when initial clinical evaluation does not support another cause. 1
Diagnostic testing for AIP
If AIP is suspected, the diagnosis should be confirmed with a porphobilinogen (PBG) urine test. 1 Prompt treatment of symptoms and disease-specific therapy should follow.
Managing AIP symptoms and precipitating factors
Acute AIP attacks require prompt treatment of symptoms and disease-specific therapy to restore heme homeostasis in order to prevent an attack from reaching the critical stage of neuronal degeneration. 2 It is also critical to identify and eliminate any potential precipitating factors.
Signs and symptoms
The clinical presentation of AIP is highly variable and non-specific. The patients are typically asymptomatic, with most gene carriers having no family history because the condition had remained latent for several generations. The syndrome marked by acute attacks affects only 10% of gene carriers. The mean age at diagnosis is 33 years old.
Pathophysiology
Porphyrias are caused by mutations in genes that encode enzymes in heme synthesis. In normal physiology, heme synthesis begins in the mitochondrion, proceeds into the cytoplasm, and finishes back in the mitochondrion.
Diagnosis
The initial diagnosis of acute porphyria is confirmed by urinalysis, including the common method, the Watson-Schwartz test. Elevated urine porphobilinogen confirms diagnosis of AIP, hereditary coproporphyria (HCP), or variegate porphyria (VP).
Treatment
If drugs have caused the attack, discontinuing the offending substances is essential. A high- carbohydrate (10% glucose) infusion is recommended, which may aid in recovery.

One of the many hypothesized diagnoses of the artist Vincent van Gogh is that he and his siblings, in particular his brother Theo, suffered from AIP and syphilis. Another theorized sufferer was King George III of the United Kingdom who even had a medallion struck to commemorate his "curing".

Summary
- Getting a diagnosis of AIP can be difficult because of how quickly each attack subsides and how infrequently they can develop in the first place. Additionally, AIP symptoms can be caused by many other neurological conditions.1 If you know you have a family history of porphyria, diagnosing the condition will probably be a quicker process. If no one else in your family has por…
A Word from Verywell
- Acute attacks of AIP are usually treated with an infusion of heme, which is created by separating heme cells from donated blood. For the best results, these infusions should be given as soon as possible after the start of a severe or moderate attack.1 Other treatments can include glucose and fluid infusions. It’s also important to address the other symptoms of AIP, like a racing heart …
Overview
- There is no cure for any form of porphyria, but treatments can relieve your symptoms and help prevent complications. While treatments for AIP are usually very effective, a delay in diagnosis or treatment can be fatal. When fatal, the primary cause of death in people with AIP is:4 1. Misdiagnosisthat led to a delay in treatment or being treated with medications that made the co…
Signs and symptoms
- Identifying the things that trigger an AIP attack will be a big part of learning to cope with AIP. For example, you might need to make some lifestyle changes and have regular heme infusions.4 While it can be overwhelming to hear that you have a rare disease, you don’t have to go through the process of learning to live with it alone. Several organizations offer resources and supportth…
Pathophysiology
- Acute intermittent porphyria (AIP) is one of a group of rare conditions that can affect the nervous system and skin. While management of the condition has improved greatly over the last few decades, it can still be fatal if it’s not diagnosed and treated correctly and quickly.
Diagnosis
- It can be hard to learn to live with a rare disorder like porphyria, and getting the right diagnosis and treatment for a rare condition can be even more difficult. However, you should rest assured that AIP is a manageable condition when it’s diagnosed and treated early. If you have family members with some form of porphyria, you may want to talk to your doctor about genetic testing for AIP—…
