Pathomorphosis of chronic gastroduodenitis in children against the background of selenium deficiency

Abstract

Purpose - to investigate the clinical and paraclinical features of the course of chronic gastroduodenitis (CGD) in children against the background of selenium deficiency. Materials and methods. Clinical and laboratory examination of 63 children (main group) aged from 7 to 18 years old, patients with CGD and 20 healthy children (comparison group) of the appropriate age was carried out. Quantitative determination of selenium in blood plasma was carried out using inductively coupled plasma mass spectrometry (ICP-MS) on an Optima 2000 DV spectrometer (Perkin Elmer, USA). Results. The average level of selenium in the blood plasma of children with inflammation of the gastric mucosa and duodenum was 73.45±4.21 μg/l, in children of the comparison group - 85.42±5.44 μg/l (p<0.05). 14 children had a selenium concentration within the normal range, and 49 patients had a significantly reduced selenium level (p<0.05), while 9 had the lowest level and was 57.2±3.5 ng/ml. Moderate erythema was recorded 3 times less often and a pronounced degree of erythema was recorded 4.6 times more often, in 4 people (8.1%) atrophy of the mucous membrane of the stomach and/or duodenum was detected, subatrophy was more often recorded (16.3%), 36.7% were diagnosed with the second degree of granularity. Was typicalhad nocturnal and «hungry» pain (22.4%). Conclusions. In the vast majority of children (77.7%), CGD occurs against the background of selenium deficiency in blood plasma. A direct correlation between the concentration of selenium in the blood plasma of sick children and the stage and activity of gastroduodenitis was established. The longer the course of the disease, the lower the levels of selenium in children's blood plasma. There is a pathomorphosis of CGD in children against the background of selenium deficiency: night and «hungry» pain, diffuse damage to the mucous membrane with erosions and subatrophy, a long course with high inflammatory activity are more common. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors.
