Undifferentiated connective tissue dysplasia in adolescents
Abstract
Objective: to study the spectrum and frequency of dysplasia-dependent and connective tissue dysplasia-associated disorders in adolescents. One hundred and ten 10-to-14-year-old pupils of one of the Leninsk-Kuznetsky schools were examined. The presence and degree of undifferentiated connective tissue dysplasia (UCTD) were established according to the phenotypic characters; joint mobility was rated using the standard Beighton methods. The adolescents showed a high prevalence of the signs of UCTD whose degree corresponded to that of joint hypermobility. The latter was accompanied by joint pain in 89 (33,3%) adolescents in the study group or concurrent with scoliosis in 77,8% and platypodia in 22,2%. In a control group (я=29), scoliosis and platypodia were 2 and 3,3 times rarer, respectively; complaints of arthralgia were absent. After 3 years, the number of adolescents with platypodia increased up to 33,3% in the study group and up to 10,3% in the control group; that of teenagers with scoliosis did up to 81,5and 41,4%, respectively. A larger number of adolescents with CTD were noted to have vegetovascular disorders, more commonly with parasympathotonia with insufficient autonomic performance support. A great difference was retained in the frequency of myopia and biliary dyskinesia and in the incidence of respiratory infections. Thus, the high prevalence of dysplasia-dependent disorders in adolescents suggests that there is a need for the early detection of the signs of CTD in children to timely implement a package of prevention and health-improvement measures.
