Abstract:
Objective To investigate the clinical and prognosis characteristics of SLE patients whose initial clinical presentations were Sj(o)gren's syndrome (SS).Methods Medical charts of 41 consecutive SS/SLE inpatients admitted to Peking Union Medical College Hospital (PUMCH) from February 1998 to February 2008 were systematically reviewed,including demographic data,clinical features,laboratory findings,treatment as well as prognosis.Two hundred and fourteen cases were randomly selected as controls from 2331 non SS-onset lupus (NSs/SLE) inpatients weated in PUMCH at the same time period.Results There were significant differences between SS/SLE and NSS/SLE patients in the following aspects (P＜0.05):①gender composition:(F/M) (41/0 vs 184/30),age at the diagnosis of SLE [(43±41) yrs vs (32±31) yrs)],disease duration L(114±84) mollths vs (45±18) months];②clinical features:xerostomia (85.3% vs 6.1%),xerophthalmia (75.6% vs 2.3%),faeial rash (9.8% vs 46.3%),renal tubular acidosis (21.9% vs 0),nephrotic syndrome (7.3% vs 31.3%),central nervous system invoivement (4.9% vs 19.6%),interstitial lung disease (12.2% vs 2.8%);③labratory findings:ESR[(65±75) mm/1 h vs (46±34) mm/1 h)],patients with elevated IgG level (56.4% vs 29.9%) and IgA level (38.5% vs 20.4%),RF,prevalence of anti-SSA and anti-SSB antibodies (70.8% vs 20.3%,82.9% vs 43.4% and 39.0% vs 7.9%);④SLEDAI score (8±8 vs 10±10),glucocorticosteroid treatment (methylprednisolone bolus/1～2 mg·kg-1·d-1 prednisone/1 mg·kg-1·d-1 prednisone)(8/26/7 vs 91/102/21),and rate of death and/or severe irreversible organ failure (2.4% vs 14.9%).SS/SLE patients were followed up for (33±34) months,40 cases remained stable and only one patient died of acute pulmonary embolism.Conclusion Compared to NSS/SLE,SS/SLE patients ale older and have more insidious disease course.They have higher prevalence rate of anti-SSA and anti-SSB antibodies,renal tubular acidosis and interstitial lung disease,but less severe neuropsychiatric and renal involvements and much better prognosis.
