Background The prevalence of anti-centromere antibodies (ACA) among patients with primary Sjögren's syndrome (pSS) varies from 3,7% till 10,9% [1;2]. They have special course of the disease: 1) with some features of systemic sclerosis (SSc), but rarely evolve to it, 2) higher prevalence of hepatitis and primary biliary cholangitis - PBC.

Objectives to describe the peculiarities of this subgroup; to evaluate it's conformity to the latest classification criteria for pSS (2012, 2016) [3;4] and prevalence of SSc with ACR2013 criteria [5].

Methods From 2012 to 2016 in a single rheumatic center 50 ACA positive patients (47 female; 3 male) national (Russian) criteria (1987) and in 68%cases - AECG 2002 criteria for pSS (SSc excluded) [Tabl.1]. The mean age was 59,2±9,6 yrs. All diagnostics methods are listed in the table 1, lymphomas were verified pathomorphologicaly with immunohystochemical staining.

Results In our study 2/3 (64%) ACA+pts with pSS did't fulfill ACR2012 criteria, because of the lack of aRo or aLa or combination of RF+ANA. According to the criteria, 2016 [4] also just 60–68% pts will have ≥4scores for diagnosing pSS. SSc (limited form) due to new criteria [5] might be revealed in 11/50 (22%) cases. MALT lymphoma of salivary glands arised in 5/6 pts with visible enlargement of parotid glands.

Characteristics of pSS patients with positive ACA

Conclusions pSS with positive ACA is challenging for diagnostics with comprehensive classification criteria (32–64% doesn't meet it [3;4]). These patients overlaps SSc, some PBC. PBC is not rare among, but biliary tract lesions (AMA+(rarely absent, 2% in our study) with slightly elevated liver enzymes, esp.GGT, and stage 1 typical to PBC without progression) are more common.
