Presentation

A 20-year-old boy presented to the emergency department with sudden onset severe left flank pain for a week and no associated vomiting or urinary symptoms. [indianjurol.com]

A conceptual model is presented and a new classification scheme discussed. Several chapters have been updated and illustrations are plentiful. [books.google.com]

Patients typically present with systemic symptoms. Obstructive intestinal symptoms are described but usually resolve with treatment of the underlying vascular disease. [ncbi.nlm.nih.gov]

Introduction Polyarteritis nodosa (PAN) presents as a necrotizing vasculitis that affects medium-sized arteries. [frontiersin.org]

Entire Body System

  • Weakness

    From 6 weeks before hospitalization, the myalgia had worsened and progressive proximal muscle weakness developed. At hospitalization, the temperature and blood pressure were 38.6°C and 110/70. [kjim.org]

    [6] Skin manifestations of PAN include palpable purpura and livedo reticularis in some individuals.[6] Neurologic system: Nerve involvement may cause sensory changes with numbness, pain, burning, and weakness (peripheral neuropathy). [en.wikipedia.org]

    Patients typically present with fever, fatigue, night sweats, loss of appetite, weight loss, and generalized weakness. Myalgias with areas of focal ischemic myositis and arthralgias are common. Affected muscles are tender and may be weak. [merckmanuals.com]

    The diagnosis of PAN is made by fulfilling 3 of the 10 classification criteria: weight loss of more than 4 kg livedo reticularis testicular pain or tenderness myalgia, weakness, or leg tenderness mononeuropathy or polyneuropathy elevated diastolic blood [aao.org]

    If muscle involvement occurs, patients may report myalgias and generalized weakness. Patients may report symptoms of neurologic disease. [ncbi.nlm.nih.gov]

  • Congestive Heart Failure

    In rare cases, testicular infarction may occur; testicular pain is usually unilateral Cardiac - Chest pain, dyspnea, palpitations, pericarditis, myocardial infarction, and congestive heart failure; cardiac disease affects 35% of patients with PAN, but [emedicine.medscape.com]

Gastrointestinal

  • Diarrhea

    Vasculitis of medium-sized mesenteric arteries causes abdominal pain, nausea, vomiting (with or without bloody diarrhea), malabsorption, intestinal perforation, and acute abdomen. Aneurysms may develop in hepatic or celiac arteries. [merckmanuals.com]

    Keywords Ischemic Colitis Polyarteritis Nodosa Bloody Diarrhea Ischaemic Colitis Miliary Tuberculosis These keywords were added by machine and not by the authors. [link.springer.com]

    Patients also may report nausea, vomiting, melena, or diarrhea. A stool occult blood test should be performed on patients even without an overt history of GI bleeding. [ncbi.nlm.nih.gov]

Cardiovascular

  • Heart Failure

    [citation needed] Cardiovascular system: Involvement of the arteries of the heart may cause a heart attack, heart failure, and inflammation of the sac around the heart (pericarditis). [en.wikipedia.org]

    History and Physical Patients with PAN and renal involvement most often present with hypertension.[6] Long-standing hypertension and vasculitis involving the coronary arteries can lead to heart failure, and patients may report associated symptoms including [ncbi.nlm.nih.gov]

    Heart failure may result from ischemic or hypertensive cardiomyopathy. Cutaneous: Livedo reticularis, skin ulcers, tender erythematous nodules, bullous or vesicular eruptions, infarction and gangrene of fingers or toes, or a combination may occur. [merckmanuals.com]

    In rare cases, testicular infarction may occur; testicular pain is usually unilateral Cardiac - Chest pain, dyspnea, palpitations, pericarditis, myocardial infarction, and congestive heart failure; cardiac disease affects 35% of patients with PAN, but [emedicine.medscape.com]

  • Tachycardia

    Bowel infarction Cholecystitis Renal symptoms Renal symptoms include the following: Hypertension Costophrenic tenderness Retroperitoneal or intraperitoneal hemorrhage Renal failure Cardiac symptoms Cardiac symptoms include the following: Hypertension Tachycardia [emedicine.medscape.com]

Skin

  • Ulcer

    Cutaneous: Livedo reticularis, skin ulcers, tender erythematous nodules, bullous or vesicular eruptions, infarction and gangrene of fingers or toes, or a combination may occur. [merckmanuals.com]

    Its features include tender subcutaneous nodules, livedo reticularis, cutaneous ulcers and necrosis. [ 4 ] It is often associated with streptococcal infection. [patient.info]

    Ulcerative cutaneous polyarteritis nodosa treated with mycophenolate mofetil and pentoxifylline. J Dermatolog Treat. 2011 Jun. 22(3):175-7. [Medline]. [emedicine.medscape.com]

    Other skin changes include livedo reticularis and ulcerations. The skin manifestations may be limited or diffuse but are often visible in the lower extremities. [ncbi.nlm.nih.gov]

  • Eruptions

    Cutaneous: Livedo reticularis, skin ulcers, tender erythematous nodules, bullous or vesicular eruptions, infarction and gangrene of fingers or toes, or a combination may occur. [merckmanuals.com]

Workup

(See Presentation, DDx, and Workup .) Stages PAN is divided into subacute, acute, and chronic stages. [emedicine.medscape.com]

Treatment

In severe cases of PAN, mortality remains high despite the appropriate treatment (4–22%) ( 34 ), since treatment-related toxicities are common. [frontiersin.org]

Obstructive intestinal symptoms are described but usually resolve with treatment of the underlying vascular disease. [ncbi.nlm.nih.gov]

In treatment, there is no specific thearpy for the ureteral stenosis if the treatment of underlying polyarteritis nodosa would affect the vasculitic process around the ureter. [kjim.org]

B when indicated Treatment of polyarteritis nodosa depends on the severity of the disease. [merckmanuals.com]

Prognosis

More important, recovery is slow and if the CNS is involved, it portends a poor prognosis. Individuals with abdominal involvement also have a poor prognosis because of the risk of perforations. [ncbi.nlm.nih.gov]

Prognosis is better if disease remission is achieved within 18 months after diagnosis. Relapses are less common than in other vasculitic disorders. [merckmanuals.com]

Gastrointestinal symptoms occur in 14-65% of patients and postprandial abdominal pain from ischaemia is the most common symptom. [ 9 ] Bowel necrosis and perforation are associated with a poor prognosis. [patient.info]

Unfortunately, a prompt diagnosis is of extreme importance, since the sooner an appropriate treatment is initiated, the better the prognosis and the less probability of permanent visual damage. [frontiersin.org]

Surgery performed for cholecystitis or appendicitis does not appear to worsen prognosis in the same way. The prognosis is better in patients with cutaneous PAN without systemic involvement. This disease is benign but tends to relapse. [emedicine.medscape.com]

Etiology

The secondary headaches include a diverse and fascinating array of etiologies which can mimic primary headache disorders ranging from the rare to the mundane and from the well established to the highly controversial. [books.google.com]

Polyarteritis nodosa was due to HBV infection, but the etiology of MN was uncertain, as it has rarely been described in PAN. Proteinuria responded to nucleoside analogue therapy. [ncbi.nlm.nih.gov]

Additionally, in 1931, Lindberg first recognized cutaneous polyarteritis nodosa (cPAN), a rare form of vasculitis of unknown etiology limited to skin, affecting small‐to‐medium‐sized arteries. [deepdyve.com]

Etiology of spontaneous perirenal hemorrhage: A meta-analysis. J Urol 2002;167:1593-6. 2. Zapzalka DM, Thompson HA, Borowsky SS, Coleman-Steenson CC, Mahowald ML, O'Connell KJ. [indianjurol.com]

A recent decrease in HBV incidence has been associated with a decrease of new cases of PAN ( 5 ), which suggests that the etiology of PAN may be linked to HBV infection. [frontiersin.org]

Epidemiology

[…] syndrome (SS), by far the most common variant (80–90% of cases), but pharmacological, gestational or paraneoplastic types of SS have been described, representing the hematologic neoplasms the 85% of the latter group, which has specific clinical and epidemiological [deepdyve.com]

Development and validation of a consensus methodology for the classification of the ANCA-associated vasculitides and polyarteritis nodosa for epidemiological studies. [frontiersin.org]

Although progress to classical PAN at a later stage has been reported, generally it is thought to be unlikely. [ 5 ] Epidemiology PAN affects approximately 3.1 per 100,000 people per year. [ 6 ] It is seen in all ethnic groups and appears to be present [patient.info]
