The correlation analysis between clinical biochemical indexes and cataract of middle aged and senior / 中华检验医学杂志

ABSTRACT

Objective A large sample of multi-factor Logistic analysis of clinical biochemical indicators from elderly cataract patients were done to find the characteristics of possible changes in potential factors for cataract-related indicators and explore the pathogenesis of cataract from the perspective of laboratory diagnosis.Methods A retrospective case control study was conducted .Cataract patients from Eye-Ear Nose Throat Hospital of Fudan University were collected during June 2011 to July 2015 and routinely tested for 14 clinical biochemistry indicators including ALB , GLU, TP, GLB, BUN, URCA, Cr, LDH, ALP, Ca, Na, K, Cl, and P.The mean age of the 3 527 cataract patients (1 804 males, 1 723 females) was (64.47 ±11.29) years.Those data were reserved by LIS (Laboratory Information System) system and were retrieved for large data analysis . The control group was filtered from hospitalized patients besides cataract patients during January 2014 to July 2015.The mean age of the 3 333 control subjects ( 1 770 males, 1 563 females ) was ( 64.04 ±9.03 ) years.Biochemical indicators between cataract group and control group were analyzed by independent student′s t-test and Logistic regression .Meanwhile , the objects were divided into 3 groups according to the age (40-59 years,60-79 years,≥80 years) for independent student′s t-test with the control group respectively .Results There are no statistical difference in age ( t=1.663,P=0.096) and gender ( t=2.63,P=0.105 0) between cataract group and control group ( P>0.05).The results of Logistic regression between cataract group and control group were as follow : ALB (OR=1.053,95%CI=1.019-1.088),BUN(OR=1.113,95% CI=1.076-1.152),Cr(OR=1.007, 95%CI=1.003-1.010),GLB(OR=1.049,95% CI=1.018 -1.081),GLU(OR=1.175,95% CI=1.139-1.211),Cl(OR=1.059,1.032 -1.088),Na(OR=1.180,95% CI =1.150 -1.212).Those might be enrolled as risk factors for cataract (P<0.05).The level of ALB, GLU, Na and Cl in cataract group according to different age groups were significantly higher ( t=8.780,t=4.670, t=9.695, t=6.415, P<0.05) than that of control in 40-59 age group;the level of ALB, BUN, Cr, GLU, Na and Cl in cataract group was significantly higher ( t=4.974, t=9.414, t=4.123, t=6.906, t=14.741, t=9.212, P<0.05) than control in 60 -79 age group; the level of BUN, Cr, GLU, Na and Cl in cataract group was significantly higher (t=6.077, t=4.906, t=2.626, t=5.459, t=3.424, P<0.05) than control in 80-age group.Conclusions The level of ALB, BUN, GLB, Cr, GLU, Na and Cl in peripheral blood of cataract patients was significantly increased which suggested that those change might associated with the pathogenesis of cataract .
