ABSTRACT
Objective To summarize the age-related changes and the risk factors of renal tubular function in the elderly male cases.Methods Totally 229 cases without chronic kidney disease were divided into two groupsgroup aged <80 years and group aged ≥80 years.We measured the urine routine,serum creatine,serum urea,urine β2-microglobin (β2-MG),urine α1-microglobin (α1-MG)and calculated the eGFR based on Cockcroft-Gault equation.Logistic regression was used to analyze the risk factors which may accelerate the progression of the renal tubular impairment.Results The average age of 229 cases was (76±10)years.There were 142 cases in the group of <80 years old and 87 cases in the group of ≥80 years old.The level of eGFR in the group of ≥80 years old was (55.0±12.7) ml/min,which was lower than that of the group of < 80 years old (80.3 ± 18.0 ml/min) (t =9.882,P<0.01).The level of urine SG was decreased in the group of ≥80 years old versus in the group of <80 years old(1.016±0.006 vs.1.013±0.006).The value changes of urine pH,urine β2-MG and urine α1-MG were of statistical differences between the two groups [(6.2±0.8) vs.(6.6±0.8),(0.96±1.02)mg/L vs.(2.08 ±3.56)mg/L,(6.67±3.57) mg/L vs.(8.71±6.59)mg/L].The correlation analysis showed that age correlated negatively with eGFR and urine SG(r =-0.692and r=-0.280,both P<0.01)and positively with urine pH(r=0.255),urine β2 MG(r=0.262),urine α1-MG(r=0.228)(all P<0.01).The Logistic regression analysis showed that coronary heart disease was an independent risk factor for the progression of renal tubular impairment (OR=4.251,P=0.002).Conclusions Renal tubular functions is decreased with ageing age in the elderly male,especially in the advanced elderly.The coronary heart disease is an independent risk factor of the progression of renal tubular impairment.
