Polyarteritis nodosa presenting with severe upper gastrointestinal bleeding: a case report.

Background: Polyarteritis nodosa is a relatively uncommon type of systemic necrotizing vasculitis that primarily affects medium-sized arteries. While gastrointestinal involvement is known in polyarteritis nodosa, heavy gastrointestinal bleeding due to gastric ulceration is relatively uncommon. We present the case of an 81-year-old male of Chinese ethnicity who experienced severe gastrointestinal bleeding as a result of polyarteritis nodosa and an innovative treatment approach for a better patient outcomes.

A case of polyarteritis nodosa with severe lower limb ulcer that was treated with prednisolone and tocilizumab.

Polyarteritis nodosa (PAN) is a rare systemic necrotizing vasculitis that can lead to the formation of refractory lower limb ulcers requiring amputation. The standard treatment for severe PAN involves combination therapy with steroids and cyclophosphamide; however, some cases prove to be challenging. Recently, case reports have described the use of biological agents for PAN treatment.

An autopsy of a patient with polyarteritis nodosa who developed fatal intestinal perforation accompanied by systemic multiple aneurysms and arterial thrombosis.

The patient was a 48-year-old man who had developed acute myocardial infarction 3 years earlier. He started experiencing recurrent attacks of abdominal pain 2 years earlier. One month before the presentation, he developed perforative peritonitis, which was treated with right hemicolectomy.

Misdiagnosed for 14 Years: Adenosine Deaminase 2 (ADA2) Deficiency in a Teen Mimicking Polyarteritis Nodosa.

The deficiency of adenosine deaminase 2 (DADA2) is an autosomal recessive disorder caused by loss of function mutations in the ADA2 gene (previously the CECR1 gene) on chromosome 22q11. The clinical spectrum of the disease is remarkably broad, and its presentations mimic features of polyarteritis nodosa, such as livedoid rash, hematological abnormalities (e.g.

Mechanisms and Screening for Atherosclerosis in Adults With Vasculitis.

Vascular inflammation is a hallmark of both primary systemic vasculitis and atherosclerosis. As such, cardiovascular events are common in patients with vasculitis and likely due to both direct vascular inflammation and accelerated atherosclerosis. Direct cardiac involvement is possible in all vasculitides, though more commonly described in Takayasu arteritis, polyarteritis nodosa, and eosinophilic granulomatosis with polyangiitis.

Long-term follow-up of anti-TNF treatment in adult and pediatric DADA2 patients: Insights from real-world data.

Background/purpose: Our objective was to investigate real-world outcomes and treatment strategies in individuals affected by DADA2 using over 10-year period real-life experience.

Methods: This descriptive analysis encompassed all adult/pediatric patients with DADA2 from our Vasculitis Research Center prospective database. Patients on anti-TNF therapy have been specifically examined, analyzing the treatment's duration, indications, and outcomes.

Hospitalist-performed skin biopsy in the diagnosis of skin disease.

In hospitalized patients, dermatologist intervention can lead to rapid identification and treatment of skin disease. However, many medical centers lack a specialized dermatologist, so skin biopsies might instead be performed by hospitalists. We aimed to determine the impact of skin biopsies performed by hospitalists on the diagnosis of skin conditions.

Deficiency of adenosine deaminase 2 (DADA2) presented with bilateral renal subcapsular hematoma: a case report and literature review.

Introduction And Importance: Adenosine deaminase 2 (DADA2) deficiency is a monogenic autoinflammatory disease caused by biallelic mutations in the ADA2 gene. Small- and medium-sized vessels may be involved and can cause various clinical symptoms, including features resembling polyarteritis nodosa (PAN). In this article, the authors discuss a unique case of DADA2 disease in which a patient presented with a bilateral renal subcapsular hematoma.

Successful treatment of cutaneous polyarteritis nodosa with baricitinib.

Polyarteritis nodosa (PAN) is a rare systemic necrotizing vasculitis preferentially targeting medium-sized arteries. PAN has two clinical entities: systemic PAN (sPAN) and cutaneous PAN (cPAN). cPAN is a skin-limited vasculitis, while ulcerative cPAN often predicts a higher risk of recurrence and a worse prognosis.

18 F-FDG PET/CT in the Evaluation of Polyarteritis Nodosa.

A 61-year-old man with a medical history of human immunodeficiency virus well controlled on antiretroviral therapy presented for distal sensorimotor symptoms, fatigue, and recurrent fevers. Erythrocyte sedimentation rate and C-reactive protein were both elevated. Antineutrophilic cytoplasmic antibody and antinuclear antibodies were negative.

Polyarteritis nodosa mimics Kawasaki disease.

Polyarteritis nodosa (PAN) is a rarely seen vasculitis that often affects small-sized and medium-sized arteries. PAN can present with diverse clinical features depending on the organs involved, including potential cardiac involvement. Typical cardiac manifestations of PAN in the paediatric age group include pericarditis, valvular heart disease and coronary artery aneurysms.

Uncommon triple vessel spontaneous coronary artery dissection in the setting of polyarteritis nodosa: a case report.

Introduction And Importance: Spontaneous coronary artery dissection is a rare cause of acute coronary syndromes not related to atherosclerosis. It involves the sudden tearing of the coronary artery wall, separating the inner intimal lining from the outer vessel wall, typically affecting a single coronary vessel. In 20% of cases, the cause of spontaneous coronary artery dissection is unknown.

Critical Limb Threatening Ischemia Due to Severe Polyarteritis Nodosa-A Case Report.

A delayed diagnosis of polyarteritis nodosa may lead to critical limb-threatening ischemia (CLTI). A 74-year-old woman presented with left-foot pain and was treated with oral vasodilators and antiplatelet agents. However, the distal ischemia progressed to CLTI, including gangrene of the fingers and toes, and bilateral foot dropping appeared because of peroneal nerve paralysis.
