The diagnosis and treatment analysis of abdominal involvement in 229 children with IgA vasculitis / 中国小儿急救医学

ABSTRACT

Objective:To summarize the diagnosis and treatment process of abdominal involvement in 229 children with IgA vasculitis and to provide reference for clinic treatment.Methods:A total of 229 pediatric patients, diagnosed as IgA vasculitis with abdominal involvement admitted to the Department of Pediatric Nephrology of Shengjing Hospital, China Medical University from January 1st 2018 to December 31st 2019, were retrospectively analyzed in the study and were divided into three groups according to Numerical Rating Scale to compare indexes in different degrees of abdominal pain.Results:The duration of hospitalization was related with degree of abdominal pain, as the more severe the abdominal pain was, the longer the hospitalization time was( P<0.001). The incidence of bloody stool were also proportionate to the degree of abdominal pain( P<0.001). With the aggravation of abdominal pain, the proportion of intestinal wall edema increased, as the highest proportion was severe group( P<0.001). The proportion of renal involvement in severe group was significantly higher than that in non-severe group( P<0.001). Twenty cases of intestinal wall edema with decreasing of albumin were treated by intravenous hormone therapy after albumin infusion as the results of no intestinal complications occurred.Compared with the mild and moderate groups, the white blood cells of the severe group were higher( P<0.001)and the albumin was lower( P<0.05). It was no significant difference in hemoglobin, serum amylase and serum lipase among three groups.The mean value of CRP had no difference among three groups and was higher than that of normal.Interleukin(IL)-6 in severe group was higher than that in other two groups( P<0.05), but there was no significant difference in IL-2, IL-4, IL-10, IL-17 and tumor necrosis factor.In terms of treatment, 40 cases were treated with immunoglobulin and four cases with hemoperfusion.The average duration of intravenous glucocorticoid application was related to the degree of abdominal pain among three groups.The longest duration was severe group(16.00±6.91)d and the shortest one was mild group(6.71±3.75)d. Conclusion:Pediatric patients diagnosed as IgA vasculitis with severe abdominal pain whose part of inflammatory indexes increased and albumin decreased obviously should complete imaging examinations to evaluate the extent of intestinal wall edema.If diagnosed as hypoalbuminemia and intestinal wall edema distinctly, hormone therapy should be given after albumin infusion to prevent severe complications such as intestinal perforation.For pediatric patients of IgA vasculitis with severe abdominal symptoms, on the basis of hormone therapy, immunoglobulin and hemoperfusion could be used to quickly remove abnormal immune substances to slow down the disease.
