Summary
Giant cell arteritis (GCA) can present with normal inflammatory markers, posing diagnostic challenges. Early combined treatment with steroids and cyclophosphamide improved vision in a GCA patient with initially normal ESR.
Area of Science:
- Rheumatology
- Ophthalmology
- Internal Medicine
Background:
- Giant cell arteritis (GCA) is a prevalent systemic vasculitis affecting individuals over 50.
- Typical GCA symptoms include headache, jaw claudication, visual disturbances, and polymyalgia rheumatica, often with elevated erythrocyte sedimentation rate (ESR).
- Prompt steroid treatment is crucial to prevent irreversible blindness.
Observation:
- A case of GCA is presented in a patient with initially normal ESR levels.
- The patient experienced severe visual impairment, perceiving only light in the left eye at treatment initiation.
- ESR levels rose to 80 mm/h immediately before initiating combined therapy.
Findings:
- Combined treatment with high-dose oral steroids and cyclophosphamide was administered.
- Significant visual improvement was observed four months post-treatment.
- This case highlights GCA's potential to occur with normal ESR, complicating early diagnosis.
Implications:
- GCA diagnosis should be considered even with normal ESR, especially in symptomatic older adults.
- Aggressive immunosuppressive therapy may be beneficial in GCA cases presenting atypically.
- Further research is warranted to understand GCA presentations with normal inflammatory markers.
