Abstract:
Objective To assess the clinical features of newly diagnosed primary Sjogren's syndrome (pSS). Methods Patients were diagnosed according to the international consensus criteria for Sjogren's Syndrome published in 2002. Clinical manifestations and laboratory tests of 86 pSS cases hospitalized in Nanjing Drum Tower Hospital in the past two years were reviewed. Results Among the 86 patients, 95.3% were female and the average disease onset age was 38.6 years. The median time from disease onset to diagnosis was 6 months. Dry mouth, dry eyes and arthralgia were the most common symptoms. Hematologic involvement was found to be prominent in these patients (69.8%). The incidence of abnormal liver function, interstitial lung disease and pulmonary arterial hypertension was 19.8%, 8.2% and 5.8% simultaneously. Younger patients (less than 18 years old) had lower frequency of dry mouth and dry eyes but higher ffrequency of fever and lymph nodes enlargement than the elderly patients (P<0.05). Patients with positive anti-SSA or anti-SSB antibodies had higher incidence of hematological changes as well as ESR than those with negative auto-antibodia. Elevated globulin/IgG and positive antinuclear antibody or rheumatoid factor (P< 0.05). Conclusion pSS is not always a benign disease. Some patients will develop vital organ damages very early and thus need to be identified and treated in time. It should not be overemphasize the importance of dry mouth and dry eyes for the diagnosis of pSS, especially in young patients. Those patients who have fever, high globulin level and positive rheumatoid factor of unknown origin should be screened for pSS.
