Retinal vein occlusion: C-reactive protein and arterial hypertension
Insights
Inflammation markers like C-reactive protein (CRP) are elevated in patients with hypertension or retinal vein occlusion. Hypertensive patients with high CRP may face a greater risk of developing retinal vein occlusion.
Area of Science:
- Ophthalmology
- Cardiovascular Medicine
- Clinical Immunology
Background:
- Retinal vein occlusion (RVO) and essential arterial hypertension are significant vascular conditions.
- Inflammatory markers are increasingly recognized as potential contributors to vascular diseases.
Purpose of the Study:
- To investigate serum C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and plasma viscosity in patients with RVO and hypertension.
- To determine if elevated inflammatory markers are associated with an increased risk of RVO in hypertensive individuals.
Main Methods:
- Serum CRP levels (log10 values), ESR, and plasma viscosity were measured.
- Patients with RVO (central and branch) and treated essential hypertension were compared to an age-matched control group.
- Statistical analysis was performed to compare marker levels between groups.
Main Results:
- Serum CRP levels were significantly elevated in both hypertension and RVO groups compared to controls (P < 0.001).
- Patients with both hypertension and RVO exhibited the highest mean CRP levels.
- ESR and serum CRP were significantly higher in hypertensive RVO patients compared to normotensive RVO patients and controls (P < 0.05 and P < 0.01, P < 0.001).
Conclusions:
- Increased inflammatory activity, indicated by elevated CRP and ESR, is associated with hypertension and RVO.
- Hypertensive patients with elevated serum CRP may have a heightened risk of developing retinal vein occlusion.
Abstract:
Eighty-six patients with retinal vein occlusion (37 with central, 49 with branch vein occlusion) and 31 patients with treated essential arterial hypertension were investigated for comparison to an age-matched control group. Serum C-reactive protein (CRP) levels, erythrocyte sedimentation rate (ESR) and plasma viscosity were measured. Serum CRP levels (log10 values) were significantly elevated in patients, with hypertension (P less than 0.001) or with retinal vein occlusion (P less than 0.001) compared to control. The highest mean value of serum CRP were found in patients with both hypertension and retinal vein occlusion, and the values of ESR and serum CRP were significantly higher in this group when compared to normotensive patients with retinal vein occlusion (P less than 0.05 and P less than 0.01, respectively) or to control (P less than 0.001). Increased inflammatory activity may be present in patients with hypertension or retinal vein occlusion. In particular hypertensive patients with elevated serum CRP levels may be more at risk of developing retinal vein occlusion.
