Abstract:
Objective:To explore the clinical characteristics of juvenile-onset ankylosing spondylitis.Methods:Clinical data of 350 cases of ankylosing spondylitis diagnosed in Beijing Jishuitan Hospital from January 2014 to December 2019 were collected. There were 75 cases with the symptom onset in age ≤16 years (juvenile-onset ankylosing spondylitis, JoAS), and 275 cases with the symptom onset in age>16 years (adult-onset ankylosing spondylitis, AoAS). The clinical characteristics of two groups were analyzed.Results:Compared with AoAS, JoAS had a higher proportion of males [98.7% (74/75) vs. 79.6% (219/275); χ 2=15.65, P<0.01] and longer course of disease [11(8,15) vs. 8(4,15) years; Z=-3.09, P<0.01]. Compared with AoAS, JoAS was more prone to have peripheral joint swelling and pain [45.3%(34/75) vs. 18.9%(52/275), χ 2=22.20, P<0.01], hip pain [26.7%(20/75) vs. 15.3%(42/275), χ 2=5.25, P=0.03] or heel pain [9.3%(7/75) vs. 2.9%(8/275), χ 2=5.93, P=0.02] as the first clinical manifestation. Compared with AoAS, JoAS had a higher incidence of radiological hip involvement [77.3%(58/75) vs. 43.3%(119/275), OR=4.71, Wald=25.60, P<0.01], lower bone mineral density than peers [34.7%(26/75) vs. 23.3%(64/275), OR=2.23, Wald=7.20, P<0.01], higher incidence of malnutrition [25.3%(19/75) vs. 13.8%(38/275), OR=2.16, Wald=5.84, P=0.02] and higher incidence of acute uveitis [17.3%(13/75) vs. 6.5%(18/275), OR=2.72, Wald=6.24, P=0.01] after adjusting the course of disease. Conclusion:Compared with adult-onset ankylosing spondylitis, juvenile-onset ankylosing spondylitis is more prone to have peripheral joint swelling or hip pain as the first clinical manifestation; the radiological hip involvement, lower bone mineral density than peers, malnutrition and uveitis are more likely to occur.
