ABSTRACT

Objective:To explore the influence of hypercholesterolemia on the risk of chronic kidney disease (CKD) in the middle-aged and elderly population and the gender differences.Methods:The data came from the "Epidemiological Survey of Chronic Kidney Disease among Adults in Urban Communities in Henan Province". The subjects came from 20 communities in Henan Province, aged ≥45 years old. Groups were based on the quartile of total blood cholesterol level and gender. Multivariate logistic regression and Cochran-Armitage trend test were used to analyze the effect of hypercholesterolemia on the risk of CKD and its gender differences.Results:A total of 4 779 subjects were enrolled into the study, with 1 934 males (40.5%) and 2 845 females (59.5%). The age was (61.3±7.7) years old and the blood cholesterol was (5.0±1.0) mmol/L. The prevalence rates of hypercholesterolemia, albuminuria, and reduced estimated glomerular filtration rate (eGFR) were 10.7%(305/2 845), 6.4%(182/2 845) and 2.8%(79/2 845) in females and 12.7%(245/1 934), 6.9%(133/1 934) and 2.3%(45/1 934) in males respectively. Compared with Q1 group, the prevalence of reduced eGFR in females were higher in Q2 and Q4 groups (both P<0.05). Among males, the prevalence of albuminuria and reduced eGFR increased with increasing blood cholesterol quartile (Cochran-Armitage trend test Z=12.231, 8.862, both P<0.001). Multivariate logistic regression analysis showed that hypercholesterolemia was an independent influencing factor for albuminuria and reduced eGFR ( OR=1.49, 95% CI 1.08-2.07, P=0.016 and OR=1.65, 95% CI 1.03-2.65, P=0.037, respectively). In subgroup analysis of different genders, female hypercholesterolemia was an independent influencing factor for albuminuria and reduced eGFR, while male hypercholesterolemia was not an independent influencing factor ( OR=1.54, 95% CI 0.96~2.46, P=0.075; OR=1.89, 95% CI 0.93-3.89, P=0.082, respectively). Further subgroup analysis based on the interquartile range of serum cholesterol levels found that female hypercholesterolemia was an independent influencing factor for reduced eGFR in the Q2 and Q4 groups ( OR=2.35, 95% CI 1.29-7.61, P=0.003; OR=2.51, 95% CI 1.38-8.39, P=0.001). In males, hypercholesterolemia was an independent influencing factor for albuminuria in the Q2, Q3 and Q4 groups ( OR=1.80, 95% CI 1.01-3.41, P=0.047; OR=1.85, 95% CI 1.02-3.35, P=0.044; OR=2.33, 95% CI 1.33-4.33, P=0.002). Conclusions:Hypercholesterolemia is an independent risk factor for CKD in middle-aged and elderly population, and there are gender differences, which provides a new idea for clinical prevention and control of CKD.

ABSTRACT

Objective@#To investigate the risk factors of clinically diagnosed acute kidney injury (AKI) patients progressing to acute kidney disease (AKD).@*Methods@#The clinical data of AKI patients admitted to the First Affiliated Hospital of Zhengzhou University from January 1, 2018 to December 31, 2018 were retrospectively analyzed. According to the outcome of the patients, AKI patients were divided into non-acute kidney disease (NAKD) group and AKD group. Clinical characteristics and laboratory data of two groups were compared. The risk factors of AKD in patients with AKI were analyzed by logistic regression, and then the receiver operating characteristic curve (ROC) was drawn to evaluate the predictive value of these risk factors.@*Results@#A total of 254 patients with AKI were enrolled, and 186 patients developed AKD with an incidence of 73.2%. The incidences of AKD in stage 1, stage 2 and stage 3 of AKI were 20.0%, 46.7% and 83.5% respectively. Multivariate logistic regression analysis showed increased peak serum creatinine (within 7 days after AKI diagnosis) (OR=2.561, 95% CI 1.584-4.140, P<0.001), proteinuria (OR=2.952, 95% CI 1.162-7.500, P=0.023) and increased intact parathyroid hormone (OR=1.757, 95%CI 1.104-2.797, P=0.017) were independent risk factors for progression to AKD in patients with AKI. The ROC showed that increased peak serum creatinine (within 7 days after AKI diagnosis) was an important predictor of AKD in patients with AKI (AUC=0.798, P<0.001).@*Conclusion@#Increased peak serum creatinine (within 7 days after AKI diagnosis), proteinuria and increased intact parathyroid hormone are independent risk factors for progression to AKD in patients with AKI, providing new evidences and ideas for clinical preventions and treatments of AKD.
