ABSTRACT
To analyze the clinical characteristics of juvenile gout,101 gout patients in Affiliasted First Hospital of Wanan Medical College from 2016 January to Decemder were divided into juvenile group (≤ 20 years,n=41) and adult group (＞20 years,n=60),the clinical data and related biochemical tests were collected.The body mass index (BMI),fasting blood glucose (FBG),TC,TG,uric acid,urea nitrogen,creatinine,cystatin C,glomerular filtration rate (GFR) and C-reactive protein (CRP),the first gout position,the duration of disease,the family history,the number of involved joints and the tophi were compared between two groups.Compared with the adult group,the juvenile group had significantly higher BMI [(25.6± 1.3) vs.(22.8± 1.0),t=-12.51)],TC [(5.55±0.51) vs.(5.07±0.54),t=-4.44),TG [(2.04±0.32) vs.(1.83±0.39),t=-2.92),uric acid[606.0 (541.0,641.0) vs.502.5 (447.5,542.2),Z=-5.65land C-reactive protein[68.0(57.0,83.5) vs.46.0 (36.0,59.8),Z=-4.64],while lower FBG [(4.83±0.68) vs.(5.74± 1.23),t=4.31)] and the number of involved joints[1(1,1) vs.2(1,4),Z=5.45].The GFR was higher in the juvenile group [(140.4± 31.0) vs.(77.7±22.5),t=-ll.81,P＜0.001)],while the urea nitrogen [6.3 (5.8,6.9) vs.7.6 (6.8,8.4),Z=5.89],creatinine [65.1 (56.2,75.1) vs.87.4 (78.5,98.4),Z=7.18] and cystatin C[1.0(0.9,1.1) vs.1.9(1.5,2.0),Z=7.66]were lower than those in adult group(all P＜0.01).The incidence of the first metatarsophalangeal joint involvement and the ankle joint involvement had no statistical difference between two groups (x2=3.434,P＞0.05).The proportion of family history of gout was higher in juvenile group (x2=6.174,P＜0.05)but the proportion of tophi was lower (x2=16.564,P＜0.01) than those in adult group.The characteristics of juvenile gout are significantly different with those of adult gout patients,so the juvenile patients should be managed differently from the adult patients.
