ABSTRACT
Objectives:
Endothelial injury may promote declining lung function. We aimed to investigate in well-treated persons living with HIV (PLWH) whether elevated levels of thrombomodulin (TM) and syndecan-1 (SDC1) are associated with excess lung function decline and worsening dyspnea.Methods:
A prospective cohort study comprising patients from the Copenhagen municipality. We included 698 PLWH with undetectable viral load. Biomarkers and demographics were measured at baseline, spirometry [forced expiratory volume in one second (FEV1) and forced vital capacity (FVC)] and dyspnea score both at baseline and 2-year follow-up.Both biomarkers were dichotomized at the 3rd quartile. Decline in lung function was estimated using a linear mixed model with patient-specific random effect. Increase in dyspnea score was estimated using a general mixed logistic regression model.Results:
We did not find an association between elevated SDC1 or TM and an excess decline in neither FEV1 SDC1 4.5 mL/year (95% CI -3.9-12.9, p = 0.30), TM 2.2 mL/year (95% CI -6.0-10.4, p = 0.60) nor FVC SDC1 4.1 mL/year (95% CI -6.0-14.2, p = 0.42), TM 1.4 mL/year (95% CI -8.3-11.1, p = 0.78). A subgroup analysis of never-smokers was consistent with the main analysis.Likewise, we did not find any association between elevated SDC1 and TM and increase in dyspnea score SDC1 OR 1.43 (95% CI 0.89-2.30, p = 0.14), TM OR 1.05 (95% CI 0.65-1.71, p = 0.26).Conclusion:
We did not find a significant association between elevated biomarkers of endothelial injury and decline in lung function nor dyspnea.
