Abstract:
Objective:To improve the understanding of Takayasu′s arteritis (TA) and its diagnosis and treatment by analyzing and summarizing the clinical characteristics of TA in children at different ages.Methods:Clinical and follow-up data of 41 children with TA admitted in Children′s Hospital, Capital Institute of Pediatrics between January 2010 and May 2020 were retrospectively analyzed.Based on the cut-off age of 3 years, children with TA were divided into older group and younger group.Clinical characteristics, involvement of the coronary artery, blood pressure control and growth restriction between 2 groups were analyzed.Counting data were expressed as percentage and case, and compared by the Chi- square test. Results:Among the 17 children with TA in younger group, there were 8 males and 9 females.There were 6 males and 18 females in older group.The general type was most common in younger group, with 10 cases (58.8%). In older group, thoracic and abdominal aortic type was the most common, with 13 cases (54.2%). The most common clinical manifestation in younger group was fever, with 13 cases (76.5%). In older group, 19 patients (79.2%) had hypertension.Lower hemoglobin (Hb) was detected in younger group.Leukocyte count, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) increased in all patients (100.0%). In older group, leukocyte count increased in 6 cases (25.0%), ESR increased in 13 cases (54.2%), and CRP increased in 11 cases (45.8%). The coronary artery and its branches (anterior descending branch and circumvolute branch) were the mostly affected in younger group, with 16 cases (94.1%). The subclavian artery was the most commonly involved in older group (15 cases, 62.5%). All TA children in younger group were in the active stage.Among them, 8 cases were treated with biological agents alone, 3 cases were treated with glucocorticoid alone, 5 cases were treated with the combination of glucocorticoid and biological agents, and 1 case was treated with glucocorticoid first, and then transferred to biological agents due to the poor effect.In older group, there were 18 active-stage patients (75.0%), and 2 refused treatment.Sixteen active patients and 6 inactive patients were treated with glucocorticoid, involving 19 cases treated with glucocorticoid combined with Cyclophosphamide, and 3 cases treated with glucocorticoid combined with biologics.There were 16 cases of coronary artery involvement in younger group and only 1 case in older group ( P<0.01). In younger group, 9 patients had growth restriction, while none was detected in older group ( P<0.01). The blood pressure of younger group was all controlled, which was not satisfactorily controlled in 16 cases of older age ( P<0.01). The incidence of general type and active stage in younger group was higher than that of older group without significant difference ( P>0.05). Conclusions:The clinical characteristics of TA vary at different ages.TA progresses more rapidly in younger children, which are more prone to the involvement of extensive vessels, the coronary arteries and other vessels, and the effects of drugs on growth and development should be well concerned.Older TA patients can be alleviated into the inactive phase by themselves, which is mainly characterized as the involvement of large vessels and hypertension sequelae.
