Polyarteritis nodosa: an evolving primary systemic vasculitis.

Postgrad Med 2022 Jun 22:1-8. Epub 2022 Jun 22.

Department of Medicine, Division of Rheumatology and Immunology, Vanderbilt University Medical Center, Nashville, Tennessee, USA.

Polyarteritis nodosa (PAN) is a primary form of vasculitis characterized by inflammation of primarily medium-sized arteries. Several key events have shaped the current spectrum of the disease including the separation of a subgroup with microscopic polyangiitis, the discovery of the association of hepatitis B, and the discovery of adenosine deaminase 2 deficiency (DADA2). With the discovery of secondary causes of PAN and changing nomenclature, the incidence of PAN has declined over time. Read More

Different Course of SARS-CoV-2 Infection in Two Adolescents With Other Immunosuppressive Factors.

Cureus 2022 Feb 28;14(2):e22710. Epub 2022 Feb 28.

Pediatrics, Nutrition and Metabolic Disorders, Children's Memorial Health Institute, Warsaw, POL.

Even after two years of the Coronavirus Disease 2019 (COVID-19) pandemic, despite known risk factors, we are still unable to predict the severity of the infection in specific patients. Due to the contradictory data, the protective role of immunosuppression in preventing the severe course of the infection remains uncertain. Therefore, we want to discuss the influence of several immunosuppressive factors on the COVID-19 pattern in children, based on two case reports regarding 17-year-old boys with other immunosuppressive factors and a completely different course of the disease.

Mechanisms of vascular inflammation in deficiency of adenosine deaminase 2 (DADA2).

Semin Immunopathol 2022 05 17;44(3):269-280. Epub 2022 Feb 17.

The MOE Key Laboratory of Biosystems Homeostasis and Protection, Life Sciences Institute, Zhejiang University, Hangzhou, China.

Deficiency of adenosine deaminase 2 (DADA2) was first described as a monogenic form of systemic vasculitis that closely resembles polyarteritis nodosa (PAN). The phenotypic spectrum of DADA2 has vastly expanded in recent years and now includes pure red cell aplasia, bone marrow failure syndrome, lymphoproliferative disease, and humoral immunodeficiency. Vasculitis remains the most common presentation of DADA2, and treatment with tumor necrosis factor inhibitors (TNFi) has shown remarkable efficacy in preventing stroke and ameliorating features of systemic inflammation.
