To study the cardiac and visceral signs of connective tissue dysplasia in children with juvenile rheumatoid arthritis, a comprehensive ultrasound examination of the abdominal cavity organs and echocardiography examination were conducted according to the standard protocol in 52 children aged from 5 to 16 years with the diagnosis of juvenile rheumatoid arthritis. The reference group consisted of 26 patients with autonomic dysfunction (vegetative-vascular dystonia). The incidence of such visceral dysplasia types as duodenogastric reflux, gastroesophageal reflux, and gallbladder malformations among children with juvenile rheumatoid arthritis was shown higher than in the reference group. The main cardiac sign of connective tissue dysplasia in patients with juvenile rheumatoid arthritis are an excessive chord of the left ventricle.

Aim. To assess adhesions of the abdominal cavity in children with varying degrees of connective tissue dysplasia (CTD) severity. Methods. A total of 91 children with average age of 10.6 1.4 years were observed from 2005 to 2019. Composed of 53 boys (58.2%) and 38 girls (41.8%). Patients were divided into two groups: group 1 (69 children without CTD) and group 2 (22 children with CTD). Clinical data and screening cards were used to diagnose DST. All patients underwent an assessment for the clinical course, a macroscopic visual assessment adhesive process severity in the abdominal cavity according to three different scales (Nair, F. Coccolini, N.I. Ayushinova). Immunohistochemistry was performed against collagen I, III, IV type, Laminin 1, angiogenesis factors, transforming growth factor beta (TGF-), and Fibroblast Growth Factor Receptor 1 (FGFR1). A semi-quantitative counting method was used to record the relative number of immunopositive structures. Statistical analysis was carried out by methods of variation statistics using the Chi-square test and MannWhitney U-tests, as well as the Spearman rank correlation method for the reliability of differences between groups. Results. In the adhesive process visualization, the N.I. Ayushinov scale was revealed to be the most informative, showing the average score of 7 0.8 points in group 2 and 14 1.2 in group 1 (rs 0.35; p 0.05). In group 2, the adhesive material showed no (56%) or chaotic fragments (44%) of type I collagen, and the ratio of type I to type III collagen is 2.7: 5.1. In group 1, the ratio of type I to type III collagen is 5.9:1.8. The ratio of collagen IV to type I is 6.5: 2.9. Both groups have a moderate (++) amount of TGF-. TGF- is positive with macrophages. FGFR1 was found in the control group (++++). A positive response was seen in fibroblasts and macrophages (U = 79.00; p = 0.006). Statistically significant analyzes of vascular endothelial growth factor in compared groups (rs = 0.632, p 0.001) had a positive correlation.. Conclusion. Thus, the study showed features of clinical course and morphological changes during the development of adhesions in the abdominal cavity in children with varying degrees of severity of CTD. Data obtained dictate the need for an individual approach in predicting adhesive disease, as well as targeted preventive care.

The aim: to improve the early diagnosis of arrhythmia in combination with gastroesophageal reflux disease (GERD) in children, by studying the risk of connective tissue dysplasia on the occurrence of this pathology. Materials and methods. We examined 100 children aged 8 to 18 years, mean age 13.7±2.7 years, of which 32 children with arrhythmias without combined pathology were group I, 36 children with concomitant GERD - group II and 32 children with GERD without concomitant arrhythmias - group III. Patients underwent clinical and instrumental studies (electrocardiography, Holter daily ECG monitoring, esophagogastroduodenoscopy and pH-metry) and evaluation of phenotypic signs of NDST according to the criteria of T. Milkovskaya-Dimitrova and A. Karkasho. Results. A risk factor for the formation of combined pathology in children in the form of arrhythmia and GERD was identified, namely the next main phenotypic feature of NDST (undifferentiated connective tissue dysplasia) – dysplastic tooth growth. Also, predictors of both an isolated variant of arrhythmia in children and arrhythmia in combination with GERD – high height and scoliotic posture were identified. In this case, the risk factor for an isolated variant of arrhythmia in children, according to the results of the study is asthenic constitution. The severity of NDST in the studied groups was determined. The analysis of the results revealed the absence of a statistically significant relationship between the severity of NDST and study groups, although it should be noted that in children of group III the first degree of NDST was not observed in general. Conclusions. It was found that asthenic constitution, dysplastic tooth growth, tall stature and scoliotic posture are statistically significant risk factors for the development of the studied pathologies. There were no statistically significant differences between the study groups regarding the severity of NDST, but there was a complete lack of detection in children of group III (children with isolated GERD without concomitant arrhythmia) of the first degree of NDST
