This study compares the clinical and serological differences between 17 PSS and 17 carefully matched CREST patients. Patients were matched for sex, age by decade, and, importantly, disease duration (11.2 +/- 9.2 vs. 12.0 +/- 9.3 years). Muscular and skin involvement were greater for the PSS groups (p less than 0.02) and pulmonary involvement was also greater (p less than 0.05), at least for non-smoking PSS patients. On the other hand no clinically significant differences were found between groups for other visceral involvement--including comparisons of gastrointestinal, cardiovascular, and renal involvement. There were also no laboratory differences except in anti-RNP antibody (p less than 0.04).
本研究比较了17例系统性硬化症(PSS)患者和17例精心匹配的CREST综合征患者的临床和血清学差异。患者在性别、按十年划分的年龄方面进行了匹配,重要的是,疾病持续时间也相匹配(分别为11.2±9.2年和12.0±9.3年)。PSS组的肌肉和皮肤受累情况更严重(p<0.02),肺部受累情况也更严重(p<0.05),至少对于不吸烟的PSS患者是这样。另一方面,在其他内脏受累方面,包括胃肠道、心血管和肾脏受累的比较,两组之间未发现临床上的显著差异。除了抗RNP抗体外,实验室检查也没有差异(p<0.04)。
