The history of polymyalgia rheumatica/giant cell arteritis
1Arcispedale Santa Maria Nuova, Reggio Emilia, Italy.
Abstract:
Only two years separate the initial descriptions of polymyalgia rheumatica (PMR) by Bruce in 1888 and giant cell arteritis (GCA) by Hutchinson in 1890. However, the existence of an association between these two conditions was definitely accepted only in 1964. Even if PMR is generally accepted as a different disease from GCA, some authors deem PMR to be a manifestation of a generalised arteritis and use the term GCA to define PMR/GCA as a whole. The time has come to clarify this issue.
Insights
Polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) were described separately but linked in 1964. This review clarifies the relationship between PMR and GCA, addressing whether PMR is a distinct condition or part of a generalized arteritis.
Area of Science:
- Rheumatology
- Vasculitis Research
- Clinical Immunology
Background:
- Polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) share a historical timeline, with initial descriptions in 1888 and 1890, respectively.
- The association between PMR and GCA was formally recognized in 1964.
- Despite general acceptance of PMR as distinct, some propose it as a manifestation of generalized arteritis, leading to the umbrella term PMR/GCA.
Observation:
- The close temporal proximity of their initial descriptions suggests a potential link.
- The established association in 1964 marked a significant step in understanding these conditions.
- Ongoing debate exists regarding the precise nosological relationship between PMR and GCA.
Findings:
- This review aims to elucidate the current understanding of the relationship between PMR and GCA.
- It addresses the controversy surrounding whether PMR represents a distinct entity or a component of a broader arteritic process.
- The findings will contribute to clarifying the diagnostic and conceptual framework for these related vasculitides.
Implications:
- Clarifying the PMR-GCA relationship can refine diagnostic criteria and improve patient management.
- A clearer understanding may impact treatment strategies and prognostic assessments.
- This work seeks to resolve ambiguity in the classification and understanding of PMR and GCA.
