ABSTRACT
Objective:
To investigate the clinical and laboratory characteristics of systemic sclerosis (SSc) patients at different age of onset.Methods:
Data of SSc patients with onset age ≥18 years old who were registered in the Peking Union Medical College Hospital and Chinese Rheumatism Data Center from August 2008 to June 2020 were included. Patients were divided into 3 groups by the age of onset according to the age segmentation of the World Health Organization. Counting variables were presented as frequency (percentage). Quantitative results were presented as mean±standard deviation, or median, inter quartile range. Differences between groups were analyzed by analysis of variance, the Mann-Whitney test or the chi-square test, depen-ding on the distribution of the variables.Results:
Six hundred and eighty-two SSc patients were included. Accor-ding to the age of onset, they were divided into three groups youth group (18-44 years old), middle-aged group (45-59 years old) and elderly group (over 60 years old). There were 361 patients in the youth group,245 patients in the middle age group and 76 patients in the elderly group. The mean age of onset was (43.8±12.1) years. The variables with significant different among the groups were as the following left ventricular diastolic dysfunction [14.0%(14/100), 38.8%(39/98), 65.4%(17/26); χ2=30.756, P<0.001]; cardiac arrhythmias [1.9% (7/361), 3.7% (9/361), 7.9% (6/76), χ2=7.38, P=0.024), Raynaud's phenomenon [94.7% (342/361), 89.4%(219/245), 89.5%(68/76), χ2=6.73, P=0.035], loss of finger pad substance [36.9%(133/360), 25.4% (62/244), 18.4% (14/76), χ2=15.184, P=0.001]; digital ulcer [31.0% (112/361), 23.0% (56/244), 15.8% (12/76), χ2=9.86, P=0.007]; arthritis [16.3%(59/361), 13.5%(33/245), 5.3%(4/76), χ2=6.49, P=0.039], digital contracture [11.6%(42/361), 5.7%(14/245), 9.2%(7/76), χ2=6.10, P=0.047]; positive anti-RNP antibody [32.3% (116/359), 20.7% (50/241), 17.3% (13/75), χ2=14.06, P=0.001]; and positive anti-centromere antibody [8.9% (32/351), 18.4%(45/239), 23.7%(18/76), χ2=17.78, P<0.001] were significantly different between the young age group and elder group.Conclusion:
The predominant age of disease onset of SSc is middle and young age. Elder onset SSc patients are more likely to have left ventricular diastolic dysfunction, and young onset patients are more likely to have microvascular lesions, which needs more attentions by clinicians.
