Abstract:
Objective To investigate the relationship between the plasma neutrophil gelatinase-associated lipocalin (NGAL)and endothelin-1 (ET-1) levels and cognitive dysfunction in chronic obstructive pulmonary disease (COPD) patients.Methods A case-control study was performed,consisting of 128 patients with COPD(68 patients without cognitive dysfunction and 60 patients with cognitive dysfunction) and 70 normal controls.All patients with COPD were diagnosed by pulmonary function tests and plasma levels of NGAL and ET-1 were determined by enzyme immunoassay.The cognitive function was evaluated by the MMSE and MoCA.Results ①Compared with normal control,the levels of plasma NGAL and ET-1 were increased(NGAL:(2.20±0.60) μg/L vs (1.69±0.73) μg/L,P＜0.05;ET-1:(26.19± 10.55)pg/ml vs (13.05±2.37) pg/ml,P＜0.05) in COPD patients without cognitive dysfunction and in COPD patients with cognitive dysfunction(NGAL:(3.80±2.75) μg/L vs (1.69±0.73) μg/L,P＜0.01;ET-1:(37.82±0.29) pg/ml vs (13.05±2.37) pg/ml,P＜0.01).Compared with the COPD patients without cognitive dysfunction,the levels of plasma NGAL and ET-1 were also increased in COPD patients with cognitive dysfunction (all P＜0.05).②The plasma NGAL levels were correlated negatively with MMSE scores(r=-0.524,P＜0.05),and negatively correlated with MoCA scores (r=-0.527,P＜0.05).The plasma ET-1 levels were negatively correlated with MMSE scores(r=-0.549,P＜0.05),and negatively correlated with MoCA scores(r=-0.558,P＜0.05).The levels of NGAL and ET-1 were positively correlated(r=0.564,P＜0.05).Conclusion NGAL and ET-1 may be involved in the pathophysiological process of cognitive dysfunction in patients with COPD,which provides a certain clinical value for the assessment of cognitive dysfunction in patients with COPD.
