Clinical characteristics and risk factors of patients with uremic encephalopathy / 中华急诊医学杂志

ABSTRACT

Objective:To analyze and compare clinical characteristics and risk factors of patients with uremic encephalopathy (UE).Methods:A retrospective analysis was performed from January 2014 to January 2019 in our hospital. Seventy patients diagnosed with chronic kidney disease (CKD) at the end stage (according to diagnosis standard of CKD) complicated with UE were classified into the UE group. In principle matching with sex, age and duration of disease, seventy patients with chronic kidney disease at the end stage but without UE were classified into the non-UE group (NUE group). The demographic data, laboratory examination, CT or MRI examination were recorded and analyzed by using t or χ 2 test. In addition, independent risk factors of patients with UE were analyzed by using Logistic model. Results:A total of 70 patients in the UE group and 70 patients in the NUE group were collected. The proportion of patients with a history of alcohol comsumption, chronic obstructive pulmonary disease and polycystic kidney disease were higher in the UE group than in the NUE group ( P<0.05). There were no significant differences in hypertension, diabetes, and coronary artery disease history between the two groups ( P>0.05). The proportion of cerebral focus and lesions for brain white matter revealed by head CT or MRI in the UE group were significantly higher than that in the NUE group ( P<0.05). The serum NLR and UA levels in the UE group were higher than those in the NUE group ( P<0.05), but the serum ALB and FT3 levels in the UE group were lower than those in the NUE group ( P<0.05). Logistic regression analysis showed that serum NLR, ALB and FT3 levels were independent risk factors for UE patients. Conclusions:Cerebral focus and lesions for brain white matter revealed by CT or MRI are typical abnormal in UE patients. The serum NLR, FT3 and ALB levels are independent risk factor for UE patients.
