Abstract:
Objective:To investigate the clinical features and etiology of 176 children with liver dysfunction, and to provide reference for the diagnosis and treatment of children with liver dysfunction.Methods:From April 2017 to February 2019, 176 children with liver function abnormalities from 2 months to 13 years old who were admitted to Hangzhou Children's Hospital were selected inthe study.The pathogens of the children's secretions were detected by fluorescence quantitative method.The blood was tested for hepatitis B virus, hepatitis C antibody and hepatitis A antibody, and blood culture method was used to detect and identify bacteria, and blood genetic metabolism and coagulation function were also screened.According to the age of the children, they were divided into infant group, toddlergroup, preschool group and school age group.Results:Among the 176 children, the infants had the most abnormal liver function, 93 cases(52.84%), followed by 43 children (24.43%) in the toddler group.Causes of the disease: 138 cases (78.41%) of the original diseases, 8 cases (4.55%) of non-infectious diseases, 30 cases (17.04%) of the undetected pathogens.Among the 138 cases with liver function abnormality due to infectious diseases, 123 cases (89.13%) were infected with virus, 8 cases (5.80%) were infected with bacteria, 6 cases (4.35%) were infected with mycoplasma, and 1 case (0.72%) was infected with Toxoplasma gondii.Among the 123 cases of liver dysfunction caused by viral infection, cytomegalovirus was detected in 62 cases (50.41%), followed by EB virus in 38 cases (30.89%), rotavirus in 10 cases (8.13%), and EV71 virus in 5 cases (4.07%), 4 cases of common enterovirus (3.25%), 2 cases of respiratory syncytial virus (1.63%), 1 case of herpes simplex virus and Coxsackie A16 virus (0.81%). Pre-school and above were mainly infected with EB virus; the age>1 year-old liver function abnormality was 37.10% (23/62) due to cytomegalovirus, and the proportion of EB virus infection was 92.11% (35/38). Compared with 62.90% and 7.89% of age 2 months to 1 year, the difference was statistically significant (χ 2=29.27, P=0.00). Eightcases of liver infection caused by bacterial infection: 3 cases of Staphylococcus aureus, 2 cases of Streptococcus pneumoniae, 2 cases of Escherichia coli, and 1 case of Pseudomonas aeruginosa.There were 3 cases of genetic metabolic diseases, including 2 cases of hepatolenticular degeneration and 1 case of glycogen accumulation.Characteristics of liver function abnormalities in children: the main clinical manifestations of children were jaundice, splenomegaly and hepatomegaly, cough, diarrhea, etc.Outcome: 98 cases (55.68%) were healed, 60 cases (34.09%) were improved, and 17 cases (9.66%) were aggravated, 1 case of death (0.57%). Conclusion:The abnormal liver function of infants was mainly caused by virus infection, especially cytomegalovirus.Infants and young children have no obvious symptoms in the early stage of the disease, severe cases can be manifested as jaundice and hepatosplenomegaly, mainly mild, with a good prognosis.
