Abstract:
Objective To explore the correlation between the distribution of uric acid (UA) level and the biochemical indicators which reflect the degree of organ lesions among hospitalized children.Methods Patients who were hospitalized to the Department of Pediatrics and received the blood UA test from June 2012 to October 2013 were included,23 217 cases in total.The biochemical analyzer-Japan's Olympus AU 2700 was used to detect blood biochemistry; and uricase-peroxidase coupling method was used to detect blood UA.Among these patients,2 099 cases whose UA level exceeded the normal level.Then the patients' gender,age,primary diagnosis and UA level were recorded; and the distribution of their UA level was described.The Chi-square or Fisher test was used to assess the incidence rate.At the same time,each blood biochemical indicators of the patients with high UA level were recorded ; and the relationships between the blood UA of the 1 650 patients with complete records and each blood biochemical indicator were analyzed with Pearson correlation analysis.Results The incidence rate of hyperuricemia among the hospitalized children was 9.04％(2 099/23 217).In particular,the incidence rate among boys and girls was 6.5t％(890/13 657) and 12.65％ (1 209/9 560) respectively (x2 =256.9,P＜0.05).The incidence rate of hyperuricemiin different diseases was as follows:in the critical illness 36.93％ (113/306),neonatal disease 20.34％ (922/4 533),urinary system diseases 12.08％ (47/389),circulatory system diseases 11.67％ (21/180),nervous system diseases 11.05％(112/1 014),digestive diseases 10.50％(190/1 810),infectious diseases 10.18％(120/1 179),blood diseases 7.58％ (55/726),endocrine system diseases 5.74％ (17/296),autoimmune diseases 4.24％ (48/1 131),respiratory diseases 3.90％ (454/11 653) respectively (x2=1423.0,P＜0.05).The incidence of hyperuricemia at younger than one month was 18.31％(929/5 075),younger than one year old was 4.22％ (359/8 501),younger than six years old was 10.68％(600/5 618),younger than 15 years old was 5.24％ (211/4 023) respectively (x2=858.5,P＜0.05).Blood UA was positively correlated to urea nitrogen,creatinine,lacticdehydrogenase,α-hydroxy-butyrate dehydrogenase,creatine kinase and creatine kinase-MB (r=0.426,0.44,0.324,0.367,0.413,0.431,P＜0.05).Blood UA was not correlated to fructosamine,blood glucose,triglycerides,total cholesterol,low-density lipoprotein and high density lipoprotein.Conclusion The incidence of hyper-uricemia among hospitalized children is high; and the incidence among children with severe diseases and newborn babies is high; followed by in children with urinary system and circulatory system diseases.The blood UA level is closely related to the blood biochemical indicators which reflect the lesions of heart and kidney.
