The patients were followed up for<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mn>11.4<\/mml:mn><mml:mo>\u00b1<\/mml:mo><mml:mn>6.2<\/mml:mn><\/mml:math>years. We evaluated the clinical and laboratory features, and assessed their influence on the time of diagnosis, survival, and mortality ratios, and compared them within subgroups defined by gender, glandular and extraglandular manifestations (EGMs), associated diseases, and immunoserological abnormalities. The most frequent EGMs were polyarthritis, Raynaud\u2019s phenomenon, and vasculitis among our patients; the most common associated disease was thyroiditis. During the follow-up period, 51 patients died; the median survival time was 33.71 years. Our results revealed a negative effect of cryoglobulinemia on survival ratios; additionally, the presence of vasculitis and lymphoproliferative diseases at the time of diagnosis increased the risk of mortality. The development of vasculitis was the most powerful predictor of mortality. Mortality in the group of patients with extraglandular symptoms was two- to threefold higher than in the glandular group. Attention is drawn to the importance of close monitoring and targeted diagnostic approaches in those pSS subgroups with obviously increased mortality risk.<\/jats:p>","DOI":"10.1155\/2014\/647507","type":"journal-article","created":{"date-parts":[[2014,5,20]],"date-time":"2014-05-20T21:15:46Z","timestamp":1400620546000},"page":"1-8","source":"Crossref","is-referenced-by-count":36,"title":["Clinical
