Polyarteritis Nodosa

Polyarteritis Nodosa






Polyarteritis nodosa is the disorder affecting the arteries of the kidneys, nerves and intestines. It causes inflammation on the arteries and is caused by autoimmune disease, affecting one’s own healthy arteries. This disorder can damage any part of the body since arteries are involved. It damages the blood vessel and is a serious illness; if not treated on time, it can be pose risk to the life of the affected person. It would also affect the joints and muscles of the intestine causing disturbance in bowel movement. The doctor would detect the disease by doing a biopsy of the tissue from the affected artery.


Polyarteritis nodosa is shortly known as PAN. If you find any organ not functioning well it may be due to poor blood supply. This disorder may also cause abdominal pain when blood supply is blocked in the arteries due to inflammation.










Causes :


Exact cause of this disorder is not known. It is believed to occur shortly after the body gets infected with hepatitis B virus.


Symptoms :


The blood vessels get damaged due to inflammation of the arteries and hence the symptoms depend on the organ that is affected. In case the blood supply gets blocked on the nerves or muscles it would cause damage to the nervous system. If the artery in the intestine or liver gets affected then it would cause abdominal pain and bloody discharge when passing stool. Fever, Weight Loss and excess of fatigue are common in this disease. There may be intermittent pain in the affected part of the body due to inflammation.


For some people, it is reflected in the form of high Blood Pressure, muscular pain, joint pain (arthralgia) and nerve damage.


Diagnoses :


The doctor would check the white blood count in the platelets and also check the sedimentation rate of the blood for identifying the disorder. It is quite common for many people to have hepatitis B when they develop PAN. In case he suspects nerve damage, then he would do nerve function tests for checking the abnormality.


In case the tissues underlying arteries are involved, he would do a biopsy for confirming the inflammation of blood vessels.


Treatment :


The main purpose of the treatment should be to reduce the inflammation of the arteries. Cortisone medicines are administered by intravenous injection or oral doses. He would also prescribe immunosuppressive medicines like cytoxan or Imuran.


If the patient has been infected with hepatitis B then he would prescribe appropriate antiviral drugs like vidarabine or interferon alpha.


The course of treatment depends on the seriousness of the illness and the health condition of the patient. Sometimes, a combination of immunosuppressive drugs and antiviral medications are given.

Prognosis :


It is for the patient to consult with the doctor once he sensed some problem without any delay. In case of inordinate delay, the inflammation of the arteries may affect the functioning of underlying organs badly. The individual should take preventive measures for not getting infected with virus causing hepatitis B.

What is Polyarteritis Nodosa?


This is a serious disease of unidentified cause that distresses the arteries, which are blood vessels that transports blood that is oxygenated to tissues and organs. It transpires when positive immunization cells attack the arteries which are affected and is referred to as a rare autoimmune disease. This disease affects the small and medium sized arteries which become swollen, inflamed and damaged.










More adults than children come down with this disease. It damages the tissues that are provided for by the arteries which are affected since the tissues are not receiving nourishment and the oxygen they need.


Polyarteritis Nodosa Symptoms


The kinds of symptoms and signs of polyarteritis nodosa differ greatly contingent on the arteries involved. Indicators may be seem in many different parts of the body and many of the difficulties can be severe and even life-threatening.


The sites that are more common for symptoms as well as complications include the nerves, eyes, kidneys, skin, heart, gastrointestinal tract as well as genitals.


Symptoms and complications of polyarteritis nodosa that distress the skin consist of:



  • Lesions or sores

  • Nodules

  • Gangrene

  • Rashes


Symptoms and complications that distress the eyes can consist of:



  • Eye and Scleritis Inflammation

  • Eye pain

  • Blurred vision


Symptoms and complications that distress the nerves consist of:



  • Tingling

  • Peripheral neuropathy

  • Pain in the extremities

  • Numbness

  • Lesions of the CNS or central nervous system

  • Lethargy

  • Altered mentation

  • Seizures

  • Cognitive difficulties


Symptoms and complications that distress the kidneys consist of:



Symptoms and complications that distress the gastrointestinal tract:



  • Gastrointestinal Bleeding

  • Shock

  • Abdominal pain


Symptoms and complications that distress the heart consist of:

  • Heart failure

  • Chest pain

  • Heart Attack

  • Shortness of breath

  • Cardiac arrest


Symptoms and complications that distress the genitals consist of:

  • Testicular pain

  • Testicular infarction

  • Swelling

  • Possible loss of testicle


Polyarteritis Nodosa Causes


Any exact cause or causes of polyarteritis nodosa are not known. But, the following facts about this condition are important.



  • Occurs twice as often in men than in women

  • Has been associated with Hepatitis B, A, C virus infections in some patients

  • Has been associated with methamphetamine use


It is possible that there are many various factors which can disturb the immune system in certain people and the immune system is triggered to cause inflammation of the blood vessel walls. The exact manner in which this occurs is not known but there is medical research being done to look for the exact reason that the immune system is mis-directed.


Polyarteritis Nodosa Diagnosis


Important indications of this condition can be delivered by routine lab test, but there isn’t one single blood test that can make a diagnosis of this illness. Many individuals with polyarteritis nodosa will have an elevated sedimentation ratio and if there is kidney envelopment, protein will be found in urine.


If any muscle, nerve or skin involvement, a muscle/nerve or skin biopsy may be an aid in arriving at a diagnosis for this disease. Conduction nerve studies are one non-invasive process of identifying any nerves distressed by inflammation. These nerves may then also be biopsied in order to verify the diagnosis. The biopsy will show some changes pathologic in the arteries that are medium-sized. Biopsy sites can differ. Many biopsies are frequently taken from symptomatic nerves, muscle or skin. An angiogram of the blood vessels of the abdomen can also be an aid in diagnosing polyarteritis nodosa. Aneurysms can often affect any arteries which are connected to the liver, gastrointestinal tract or kidneys.


“The American College of Rheumatology” or ACR has criteria which has been established which needs to be fulfilled for any individual to be involved in any studies or research of the condition. This criterion is designed to distinguish this disease from other forms of Vasculitis. So as to be diagnosed as a patient of this disease – especially for the purposes of research studies, an individual will need to have 3 out of 10 of the following criteria:



  • Loss of weight of > 4 kg from start of illness

  • Testicular tenderness or pain

  • Myalgias, leg tenderness or weakness

  • Livedo Reticularis

  • Growth of hypertension

  • Mononeuropathy or polyneuropathy

  • Raised creatinine or BUN unrelated to obstruction or dehydration

  • Arteriogram signifying occlusions or aneurysms of the visceral arteries

  • Existence of hepatitis B surface antibody or antigen in serum

  • Biopsy of medium and small-sized artery having Granulocytes


Polyarteritis Nodosa Treatment


Systemic polyarteritis nodosa in the era of pre-treatment had a terrible prognosis with a five year survival rate of approximately 10%.


Medications now used to treat this condition can include:



  • High dose intravenous and oral cortisone – such as prednisone

  • Immunosuppressive drugs:  Cyclophosphamide (known as Cytoxan)  & Azathioprine (known as Imuran)


As oral cortisone medication begins to work and the sedimentation rates begin to return to normal, gradual tapering of the oral cortisone medication may begin.


When hepatitis B is also present in individuals with polyarteritis, antiviral medication such as:



  • Vidarabine

  • Interferon-alpha


are used as primary treatments. Several studies have used various combinations of the following:



  • Antiviral medications

  • Plasma exchanges

  • Immunosuppressive drugs
