Abstract

SANCILIO, Andrea et al. Unusual presentation of SARS-CoV-2 infection simulating Schönlein Henoch purpura (immunoglobulin A vasculitis). Rev. argent. reumatolg. [online]. 2022, vol.33, n.2, pp.90-96. ISSN 0327-4411.  http://dx.doi.org/10.47196/rar.v33i2.475.

Immunoglobulin A vasculitis, previously called Henoch Schonlein purpura (IgAV/HSP), is the most common systemic vasculitis in childhood. The most common trigger is a previous upper respiratory infection. It is characterized by palpable non-thrombocytopenic purpura with arthralgia and/or arthritis, gastrointestinal and kidney involvement.

SARS-CoV-2 is an RNA virus that causes COVID-19 disease. It frequently affects the respiratory system with presentations ranging from rhinitis to severe conditions such as respiratory distress syndrome, septic shock, or multi-system inflammation syndrome (MIS).

We describe the case of a 5-year-old boy with symptoms of IgAV/HSP as the initial form of presentation and subsequent diagnosis of SARS-CoV-2 infection, being referred to a more complex hospital with hypertensive encephalopathy, presenting a favorable evolution and complete restoration of the clinical picture.

Keywords : IgA vasculitis; COVID-19; SARS-CoV-2; Henoch Schonlein purpura; pediatrics.
