Pathogenesis of polyarteritis nodosa in hypertensive rats.

Effect of diet on experimental hypertension and on the development of polyarteritis nodosa in rats.

The renin–angiotensin system as a primary cause of polyarteritis nodosa in rats

Polyarteritis nodosa is a necrotizing vasculitis of medium-sized arteries of unknown origin. Hypertension is present in 30% of patients with polyarteritis nodosa. In those cases, high renin levels are thought to be secondary to renal involvement. The present study was performed to identify causal factors of polyarteritis nodosa. In cyp1a1ren-2 transgenic rats, vasculitis of medium-sized arterie...

Co- infectious Cytomegalovirus and Pneumocystis Jiroveci Pneumonia in a Polyarteritis Nodosa Patient: A Case Report

Our report discusses a patient diagnosed with PAN since 3 years ago. He presented with fever, chills and nonproductive cough. He was a long time receiver of immunosuppressant drugs for his underlying condition. Upon examination he was febrile, had cushingoid appearance and cackles in both lungs. Lung CT scan showed opacities in right upper lobe lung and multiple bilateral nodules and ground gla...

Polyarteritis Nodosa

Polyarteritis nodosa (PAN) is the systemic necrotizing vasculitis on small and median muscular vessels. Recent studies reveal that PAN consists of classical PAN and microscopic polyangitis (MPA). MPO-ANCA, which is one of anti-neutrophil cytoplasmic antibody (ANCA), is involved in the pathogenesis of MPA. In future, by the progress of research of ANCA, the definition or criteria of systemic vas...

Childhood polyarteritis nodosa: a clinical diagnosis.

A six-year old boy presented with dry gangrene of toes and fingers with hypertension with no other systemic abnormalities. He had persistently high inflammatory parameters, was diagnosed as childhood classic polyarteritis nodosa and showed improvement with immunosuppressants along with antihypertensives. Toe gangrene required amputation in view of superadded infection.
