目的研究老年人。肾功能损害与罹患肺部感染的关系。方法选择年龄〉65岁老年患者224例,根据慢性肾脏病分期及估算肾小球滤过率(eGFR)分为5组:〉t90ml/(min·1.73m2)为对照组(A组)65例、60~89ml/(min·1.73m2)组(B组)55例、30~59ml/(min·173m。)组(C组)27例、15—29ml/(min·1.73m2)组(D组)28例和〈15ml/(min·1.73m2)组(E组)49例。采用Logistic回归分析肾功能与肺部感染之间的关系。结果与A组比较10.8%(7/65),C组63.0%(17/27)(χ2=26.95,P〈0.05),D组85.7%(24/28)(χ2=49.46,P〈0.05)及E组100%(49/49)(χ2=89.00,P〈0.01)患者肺部感染发生率均明显升高,差异均有统计学意义。吸烟(Waldχ2=17.66,P〈0.01),呼吸道基础疾病(Waldχ2=14.38,P〈0.01),侵袭性操作史(Waldχ2=4.50,P〈0.05),糖尿病(Waldχ2=3.86,P〈0.05),住院满2周(Waldχ2=18.18,P〈0.001),性别(Waldχ2=4.12,P〈0.05),eGFR(Waldχ2=13.57,P〈0.01)是老年人患呼吸道感染的危险因素。Logistic回归分析显示,调整影响肺部感染危险因素后,eGFR水平≥90ml/(min·1.73m2)(Waldχ2=0.053,P〉0.05),60~89mV(min·1.73m2)(Waldχ2=0.046,P〉0.05),30~59ml/(minl·1.73m2)(Waldχ2=7.61,P〈0.05),15—29ml/(min·1.73in。)(Waldχ2=4.38,P〈0.05),〈15ml/(min·1.73m。)(Waldχ2=13.57,P〈0.01),罹患肺部感染风险随eGFR的降低而增加。结论年龄〉65岁老年患者肾功能损害是其患肺部感染的一个独立危险因素。
Objective To study the relation between kidney function impairment and respiratory tract infections( RTI ) in the elderly. Methods Two hundred and twenty-four patients above 65 years old were divided into five groups according to stages of chronic renal disease and estimated glomerular filtration rate (e GFR):(Agroup,n=65):l〉90ml/(min·1.73 m2),(B group,n=55):60-89 ml/(min · 1.73 m2),(C group, n = 27 ) : 30 - 59 ml/( min · 1.73 m2 ) , ( D group, n = 28 ) : 15 - 29 ml/( min · 1.73 m: ) and ( E group, n =49) : 〈 15 ml/( min · 1.73 m2 ). Taking A group as the control baseline. Logistic regression was employed to analyze the relationship between kidney function and RTI. Results Compare with A group (10. 8% 3/65 ) ,the incidences of RTI in three groups( C group, D group and E group were 63.0% ( 17/27 ), 85.7% (24/28) and 100% (49/49) respectively. The incidence in these groups was higher than that in A group( χ2 = 26. 95,49.46 and 89. 00 respectively,P 〈 0. 05 ). We identified the risk factors with RTI were smoking( Waldχ2 = 17. 66, P 〈 0. 01 ), respiratory underlying diseases (Waldx2 = 14. 38, P 〈 0.01 ), invasive operation history ( Waldχ2 = 4. 50, P 〈 0.05 ), diabetes ( Waldχ2 = 3.86, P 〈 0.05 ), stay in hospital for above 2 weeks ( Waldx2 = 18. 18, P 〈 0.01 ), Gender( Waldχ2 = 4. 12, P 〈 0. 05 ), eGFR ( Waldx2 = 13.57, P 〈 0. 01 ). After adjusting for other risk factors of RTI, Logistic regression analysis showed that the risk of RTI still increased with the decrease of eGFR ( eGFR I〉 90 ml/( rain · 1.73 m2 ) : ( Waldχ2 = 0. 053, P 〉 0. 05 ) ; 60 - 89 ml/(mm· 1.73 m2 ) : ( Waldx2 = 0. 046 ,P 〉 0.05 ) ;30 - 59 ml/( min·1.73 m2 ) : ( Waldχ2 = 7. 61 ,P 〈 0. 05 ), 15 - 29 ml/( min· 1.73 m2) : (Waldχ2 =4.38,P〈0.05) ; 〈15 ml/(min · 1.73 m2) : (Waldx2 =13.57,P〈0.01)). Conclusion Kidney function impairment in patients above 65 years old is an independent risk factor for RTI.
