Abstract. There is a tendency to an increase in the frequency of hospitalization of children with mixed forms of IgA-vasculitis with pronounced abdominal syndrome and involvement in the pathological process of the kidneys, which is possibly associated with an increase in the level of comorbid pathology of the gastrointestinal tract, and with a premorbid state of the mucosa membranes of the digestive system. There is a need to study the course and evolution of IgA vasculitis in children with gastrointestinal manifestations in order to improve the diagnostic search, accurate prognosis and create a standardized treatment protocol for IgA vasculitis in children. Objective. To investigate the clinical and diagnostic manifestations and evolution of IgA vasculitis in children with lesions of the gastrointestinal tract. Materials and method. The surveys of patients and their parents and retrospective analysis of 58 maps of inpatients with IgA vasculitis and digestive lesions aged 0 to 18 years, who were hospitalized in the somatic departments of the National Children's Specialized Hospital " OKHMATDYT" Kyiv, Ukraine in the period from 2008 to 2018. Results. The mean age of children with IgA vasculitis was 8,03 years, and the ratio of boys to girls was 1,32: 1. Skin syndrome occurred in 58/58 patients (100%), and joint symptoms were observed in 34/58 (58,62%) patients. There were 29/58 patients (50,0%) with kidney disease. The incidence of renal pathology was higher in children with severe symptoms of the digestive system and in persons older than 7 years. 23/29 (79,31%) patients had manifestations of kidney damage in the first month after the onset of IgA vasculitis with gastrointestinal symptoms. Conclusions. In the study among hospitalized children, clinical and laboratory features and the evolution of IgA vasculitis in children with gastrointestinal lesions were similar to the literature. In 79,31% of patients, the onset of renal syndrome occurred in the first month after the onset of IgA vasculitis. In 20,69% of patients there was an evolution of kidney damage into chronic kidney disease. Therefore, careful monitoring of renal impairment should be performed to assess the progression of chronic kidney disease in patients who develop IgA vasculitis over 7 years of age and in those children who have severe symptoms of gastrointestinal damage. |
