The following is a summary of “Characterization of non-IgA vasculitis: Demographic, clinical, and treatment-related features in a retrospective analysis of 28 biopsy-confirmed cases from a German university hospital,” published in the November 2024 issue of Dermatology by Hansen-Abeck et al. 

Non-IgA vasculitis is a rare small-vessel vasculitis with limited published data due to current nomenclature and classification changes.    

Researchers conducted a retrospective study to describe non-IgA vasculitis as an independent entity based on demographic, clinical, and treatment-related features.    

They analyzed data from 28 individuals with biopsy-confirmed non-IgA vasculitis, cured at the Department of Dermatology at the University Medical Center Hamburg-Eppendorf between January 1, 2018, and December 31, 2022.    

The results showed that 28 patients with non-IgA vasculitis were included, with 53.6% (15/28) women and 42.9% (12/28) older than 71 years. Previous infections were identified as triggers in 42.6% (12/28) of cases. Palpable purpura was the most familiar skin finding (78.6%, 22/28), and 28.6% (8/28) had lesions above the waist. C3 deposition was most frequent on direct immunofluorescence (89.3%, 25/28), followed by fibrinogen (71.4%, 20/28) and IgM (53.6%, 15/28). Hospitalization was required for 85.7% (24/28) with a mean stay of 9.4 ± 4.1 days with no fatalities.    

Investigators concluded that non-IgA vasculitis, primarily affecting older patients, is an independent entity with identifiable triggers and extended cutaneous manifestations, requiring hospitalization but not leading to fatal outcomes with proper treatment.
