VERA FRANCO, Víctor Jonathan et al. Schönlein-Henoch purpura in an adult patient. Rev. virtual Soc. Parag. Med. Int. [online]. 2022, vol.9, n.2, pp.153-159. ISSN 2312-3893.

Schönlein-Henoch purpura is an immune-mediated leukocyte fragmentation vasculitis that affects small blood vessels. The four essential clinical components are purpura, abdominal pain, arthralgia, and renal involvement. This case concerns a 50-year-old woman who is admitted due to abdominal pain and hematochezia of 72 hours of evolution, after an exploratory laparotomy. On physical examination, she presents purpuric lesions on the trunk and lower extremities of 2 months of appearance. In paraclinical tests, a blood count with normal platelets, urine protein 500 mg/dL, and proteinuria 2.4 g/24 hours are observed. Suspecting vasculitis with plausible cutaneous-renal inclusion, antinuclear antibodies and ANCA are requested, and a skin biopsy is performed, showing necrotizing neutrophilic vasculitis of small vessels. In the renal biopsy, IgA deposit, C3 positive is observed in the direct immunofluorescence. In the clinical relationship of proteinuria and skin involvement together with the confirmation of renal biopsy, the diagnosis of Schönlein-Henoch purpura is concluded. The interest of this case lies in the inconsistency of this pathology in adults, despite the fact that it could be more serious given that there is a greater risk of persistent renal failure.
