title: The Association between ESR and CRP and Systemic Hypertension in Sarcoidosis.
abstract: Introduction. The association between the level of systemic inflammation and systemic hypertension (sHTN) among subjects with sarcoidosis has not been previously explored. Methods. A retrospective study was conducted to investigate the relation between the level of systemic inflammation in sarcoidosis, measured by various serum inflammatory markers, and sHTN. Results. Among a total of 108 cases with sarcoidosis (mean age: 53.4 years, 76.9% females), 55 (50.9%) had sHTN and 53 (49.1%) were normotensive. ESR was highly associated with sHTN. The patients with sHTN had higher mean ESR levels compared with normotensives (48.8 ± 35 versus 23.2 ± 27 mm/hr, resp.; P = 0.001). ROC curve analysis for ESR revealed an AUC value of 0.795 (95% CI: 0.692-0.897; P = 0.0001). With regard to CRP, there was a trend towards higher mean values in sHTN group (3.4 versus 1.7 mg/L; P = 0.067) and significantly higher prevalence of sHTN in the highest CRP quartile compared to the lowest one (69.6% versus 30%; OR 4.95; P = 0.017). ROC curve analysis for CRP revealed an AUC value of 0.644 (95% CI: 0.518-0.769; P = 0.03). On multivariate analysis, ESR and the CRP remained independent predictors for sHTN among subjects with sarcoidosis. Conclusion. Systemic inflammation is associated with the presence of sHTN in sarcoidosis.
