Henoch-Schönlein purpura synonyms

Henoch-Schönlein purpura, now formally referred to as IgA vasculitis, is a systemic small-vessel vasculitis characterized by the deposition of IgA-dominant immune complexes. Due to its historical classification based on clinical observation rather than pathophysiology, Henoch-Schönlein purpura is frequently referred to by several synonymous names in medical literature and patient records.

What are the primary synonyms for Henoch-Schönlein purpura?

While the medical community is moving toward the nomenclature "IgA vasculitis," many clinicians still use the term Henoch-Schönlein purpura in practice. You may encounter the following names in your medical records or older literature:

• IgA vasculitis (The current preferred clinical term)


• Anaphylactoid purpura


• Allergic purpura


• Rheumatic purpura


• HSP (The common abbreviation)

Why does Henoch-Schönlein purpura have so many names?

The naming of Henoch-Schönlein purpura reflects the evolution of medical diagnostics. Originally named after physicians Eduard Henoch and Johann Lukas Schönlein, who described the condition in the 19th century, the name was purely descriptive of the skin findings (purpura). As researchers discovered that the disease involves the deposition of immunoglobulin A (IgA) in the blood vessels, the International Chapel Hill Consensus Conference on the Nomenclature of Vasculitis officially recommended the term "IgA vasculitis" to better reflect the underlying pathology.

How is the condition classified internationally?

Standardized medical databases use specific codes to identify Henoch-Schönlein purpura to ensure consistency across global healthcare systems:

1. ICD-10/11: Classified under D69.0 (Allergic purpura) or equivalent vasculitis codes.


2. Orphanet: Listed as ORPHA:76116, consistently updating to reflect the IgA vasculitis transition.


3. OMIM: Often referenced in the context of systemic vasculitis research.
