Objective: to compare clinical and laboratory manifestations in 2 groups of patients with primary Sjogren’s syndrome (pSS): with and without anticentromere antibodies (ACA); compare the incidence, clinical and laboratory characteristics of lymphomas in these two groups.Materials and methods. We examined 119 patients with ACA-positive pSS (pSS-ACA+). pSS was diagnosed based on Russian 2001 criteria, systemic sclerosis (SSc) – criteria ACR/EULAR 2013. To diagnose liver diseases, the level of transaminases, alkaline phosphatase and antimitochondrial antibodies (AMA) was determined, as well as liver biopsy. The diagnosis of primary biliary cholangitis (PBC) was established according to the recommendations of the American Association for the Study of Liver Diseases, the Russian Gastroenterological Association and the Russian Society for the Study of the Liver. Lymphomas were diagnosed according to histological, immunohistochemical and molecular studies of affected organs biopsies, according to the classification of the World Health Organization. A combination of pSS and SSc was diagnosed in 37 patients, and they were excluded from further analysis. We compared clinical and laboratory features in patients with pSS-ACA+ (n=82) and ACA-negative pSS (pSS-ACA–, n=64) and characterized lymphomas in the pSS-ACA+ (n = 14) and pSS-ACA– (n=10) groups.Results and discussion. In patients with pSS-ACA+, a later age of disease onset was revealed, the duration of the disease before lymphoma development did not differ. In patients with pSS-ACA+, we found a lower frequency of rheumatoid factor (RF), antibodies to Ro (anti-Ro) and La (anti-La), decreased C3-complement, hypergammaglobulinemia, increased IgG concentration, CRP, increased ESR, leukopenia and anemia. 51.2% of patients with pSS-ACA+ were seronegative for anti-Ro, anti-La and RF. Patients with pSS-ACA+ had a higher frequency of AMA and elevated IgM. The incidence of cryoglobulinemia and paraproteinemia did not differ. The frequency of recurrent parotitis in pSS-ACA+ was significantly lower, there were no differences in the frequency and severity of other signs of salivary and lacrimal gland damage. PBC and epitheliitis of the biliary ducts in patients with pSS-ACA+ were detected significantly more often. Damage to the peripheral nervous system, lungs, hypergammaglobulinemic purpura, arthralgia and autoimmune thyroiditis were significantly more often detected in the group of patients with pSS-ACA–. In the pSS-ACA+ group, Raynaud’s phenomenon was significantly more frequent, mainly with scleroderma-type capillaroscopic abnormalities. There was no difference in the frequency of other signs characteristic of SSc. MALT lymphomas were diagnosed in the study groups with the same frequency. Patients with lymphomas in the pSS-ACA+ group were characterized by significantly higher laboratory activity. All patients with lymphomas in both groups showed persistent parotid salivary gland enlargement. Lymphomas in both groups developed in patients with late stage salivary and lacrimal gland damage, systemic manifestations of pSS in both groups were rare.Conclusion. pSS-ACA+ is an independent subtype of pSS, which has a number of significant clinical and laboratory differences from the “classic” variant of the disease. ACA in pSS are associated with a low frequency of anti-Ro, anti-La, and RF, as well as an increased risk of PBC and limited SSc. MALT lymphomas in the pSS-ACA+ and pSS-ACA– groups developed with the same frequency and were associated with the progression of glandular damage, regardless of the presence of systemic manifestations.

Primary Sjögren’s syndrome (pSS) is a chronic systemic autoimmune rheumatic disease characterized by lymphoplasmacytic infiltration of the salivary and lacrimal glands, whereby sicca syndrome and/or systemic manifestations are the clinical hallmarks, associated with a particular autoantibody profile. pSS is the most frequent connective tissue disease after rheumatoid arthritis, affecting 0.3–3% of the population. Women are more prone to develop pSS than men, with a sex ratio of 9:1. Considered in the past as innocent collateral passive victims of autoimmunity, the epithelial cells of the salivary glands are now known to play an active role in the pathogenesis of the disease. The aetiology of the “autoimmune epithelitis” still remains unknown, but certainly involves genetic, environmental and hormonal factors. Later during the disease evolution, the subsequent chronic activation of B cells can lead to the development of systemic manifestations or non-Hodgkin’s lymphoma. The aim of the present comprehensive review is to provide the current state of knowledge on pSS. The review addresses the clinical manifestations and complications of the disease, the diagnostic workup, the pathogenic mechanisms and the therapeutic approaches.

The aim of this retrospective, single-centre study was to investigate the clinical and laboratory features and disease outcomes of 547 patients diagnosed with primary Sjögren’s syndrome (pSS) between 1975 and 2010. The patients were followed up for11.4±6.2years. 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’s 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.
