Insights
Giant cell arteritis (GCA) patients with transient cerebro-ophthalmic ischemic episodes (COIEs) and without systemic symptoms face higher risks of cranial ischemic complications (CICs). Early CICs and later COIEs predict new CICs during follow-up.
Area of Science:
- Rheumatology
- Neurology
- Ophthalmology
Background:
- Cranial ischemic complications (CICs) are significant manifestations of giant cell arteritis (GCA).
- CICs can occur at presentation or develop later, even with steroid treatment.
- Identifying risk factors is crucial for managing GCA and preventing CICs.
Purpose of the Study:
- To identify risk factors for CICs at GCA presentation.
- To determine risk factors for new-onset CICs during GCA follow-up.
- To review existing literature on GCA-related CICs.
Main Methods:
- Retrospective chart review of 175 GCA patients.
- Follow-up data analyzed for 166 patients.
- Multivariate analysis to assess associations between CICs and clinical variables.
Main Results:
- At presentation, 24.6% of patients had CICs. Risk factors included transient cerebro-ophthalmic ischemic episodes (COIEs) and male sex. Systemic symptoms were protective.
- During follow-up, 8.4% developed new CICs. Risk factors were prior CICs and new COIEs. Low-dose aspirin showed a protective effect.
- Patients with COIEs and lacking systemic symptoms were at higher risk for presenting CICs.
Conclusions:
- Transient COIEs and absence of systemic symptoms are key risk factors for presenting CICs in GCA.
- Previous CICs and developing COIEs during follow-up increase the risk of late-onset CICs.
- Low-dose aspirin may offer protection against late-onset CICs in GCA patients.
Abstract:
Cranial ischemic complications (CICs) are among the presenting manifestations of giant cell arteritis (GCA). Yet patients with GCA may develop CICs at a later stage, despite steroid therapy. In the current report we delineate risk factors for CICs, both at presentation and during follow-up, and review the relevant literature. We reviewed charts of 175 patients with GCA. Follow-up data were available for 166 patients. CICs at presentation or developing within 2 weeks of GCA diagnosis were considered GCA related. CICs developing later were considered GCA related only when associated with other GCA-related manifestations or acute-phase reactions. Associations between CICs and other variables were tested by multivariate analysis. At presentation, 43 patients (24.6%) had CICs. Risk factors were transient cerebro-ophthalmic ischemic episodes (COIEs) (odds ratio [OR] 4.3) and male sex (OR 2.5), while the presence of systemic symptoms was "protective" (OR 0.3). During follow-up 8.4% of patients with GCA developed new CICs. Risk factors in these cases were previous CICs at presentation (OR 5.6) and transient COIEs developing during follow-up (OR 14.8). The use of low-dose aspirin was protective (OR 0.2). These data, together with data from the literature review, suggest that GCA patients with transient COIEs and without fever or other systemic symptoms are at increased risk of presenting with CICs. Risk factors for late-developing CICs were CICs at presentation and late-developing transient COIEs.
