Giant cell (temporal) arteritis-polymyalgia rheumatica: a critical review
1Ipswich Hospitals, Suffolk.
Giant cell (temporal) arteritis is a common inflammatory condition affecting large arteries in individuals over 50. This review highlights controversies and neglected aspects, including its potential underdiagnosis and involvement of intracerebral vessels.
Area of Science:
- Rheumatology
- Vascular Medicine
- Epidemiology
Background:
- Giant cell (temporal) arteritis (GCA) is a prevalent vasculitis affecting medium and large arteries.
- Up to 50% of polymyalgia rheumatica (PMR) patients may develop GCA manifestations.
- GCA diagnosis can be challenging, with potential for underdiagnosis.
Purpose of the Study:
- To critically review controversial and neglected aspects of Giant Cell Arteritis.
- To emphasize the need for urgent clarification on intracerebral vessel involvement.
- To highlight the implications of symptomatically silent but active GCA.
Main Methods:
- Critical literature review.
- Analysis of epidemiological data, including autopsy statistics.
- Discussion of clinical implications and diagnostic challenges.
Main Results:
- Autopsy data suggest GCA is more common than clinically diagnosed.
- Uncertainty persists regarding intracerebral vessel involvement in GCA.
- GCA can be active and asymptomatic, posing diagnostic difficulties.
Conclusions:
- GCA diagnosis and management require further research into epidemiology and vessel involvement.
- Clinicians must consider the possibility of silent GCA, especially in at-risk populations.
- Urgent research is needed to address diagnostic gaps and treatment implications, particularly concerning stroke management.
