RESUMO

The objectives of this study were to describe the clinical features and evaluate the utility of immunological features as predictors of organ involvement and disease severity in patients with primary Sjogren's syndrome (pSS). In this single-center observational cross-sectional study, subjects fulfilling the 2012 AECG criteria or 2016 ACR/EULAR criteria for pSS were included. Details of glandular, extra-glandular manifestations, ESSDAI, ESSPRI, ANA, anti-Ro/La antibodies, rheumatoid factor (RF), complement (C3 and C4) levels and hyperglobulinemia were noted. Chi-square and Mann-Whitney U tests were performed for determining associations and relative risk (RR) was calculated. Sixty-four subjects with pSS were included in the study. Females constituted 92% and median age at onset was 37.5 (15-74) years. Ocular or oral sicca was noted in 61 (95.3%) subjects and parotidomegaly was noted in 17 (26.5%) subjects. Extra-glandular manifestations noted were: constitutional (85.9%), articular (65.6%), renal (29.6%), hematological (26.6%), cutaneous (12.5%), peripheral nerves (9.3%) and pulmonary (4.7%). Immunological features noted were: ANA (85.9%), anti-Ro (81.3%), anti-La (60.9%), RF (84.4%), hypocomplementemia (39.1%) and hyperglobulinemia (62.5%). Median ESSDAI was 6 (0-23) and ESSPRI was 7 (0-10). ANA was associated with younger age and renal involvement (RR 1.25). Anti-Ro was associated with younger age, renal involvement (RR 1.36) and high ESSDAI. Anti-La was associated with high renal (RR 3.4) and low articular involvement (RR 2.75). RF was associated with hematological involvement and hyperglobulinemia was associated with younger age. Certain immunological features can help predict the organ involvement in patients with pSS. Larger, prospective follow-up studies are needed to clearly understand these associations.
