PURPOSE: To investigate the relationship between serologic markers and dry eye severity in subjects with primary Sjögren syndrome (SS).
METHODS: This study evaluated 64 patients diagnosed with primary SS according to the 2012 Sjögren's International Collaborative Clinical Alliance (SICCA) classification criteria. Serum anti-Ro/SSA, anti-La/SSB, rheumatoid factor (RF), and antinuclear antibody (ANA) levels, Ocular Surface Disease Index (OSDI), Schirmer I test values, tear film breakup time, and SICCA ocular staining score (OSS) were determined.
RESULTS: The conjunctival staining scores were 3.3 ± 1.9, 3.6 ± 2.0, 3.4 ± 1.9, and 3.5 ± 1.9 in the positive anti-Ro (≥25 EU), positive anti-La (≥25 EU), positive RF (≥20 IU/mL), and positive ANA (≥1:320) group, respectively. Subjects with positive anti-Ro, anti-La, RF, or ANA had significantly higher conjunctival staining scores compared with those with negative levels (P < 0.05). The total OSS in the positive ANA group was 5.5 ± 3.0, which was significantly higher than the total OSS (3.4 ± 2.1) in the negative ANA group (P = 0.005). Serum RF and ANA levels had strong correlations with conjunctival staining scores and the total OSS but not with corneal staining scores (r = 0.53, P < 0.001 and r = 0.382, P = 0.002). Other ocular parameters (OSDI, Schirmer I test values, and tear film breakup time) did not differ by the serologic marker level. Interestingly, the OSDI was positively correlated with the corneal staining score and total OSS (r = 0.646, P < 0.001 and r = 0.476, P < 0.001).
CONCLUSIONS: Serum RF and ANA levels are associated with conjunctival staining scores and the total OSS according to the SICCA OSS in primary SS.
