Resumo: | Abstract Introduction: The presence of anti-Ro52 antibodies has been reported in a wide variety of autoimmune diseases, particularly in myositis, scleroderma and autoimmune liver diseases. Clinical significance of anti-Ro52 antibodies remains controversial. Studies are lacking in clarifying the association of anti-Ro52 with pulmonary involvement in scleroderma. Objectives: To determine if anti-Ro52 antibodies are associated with pulmonary involvement (interstitial, indirect pulmonary hypertension, or both) in scleroderma. Methods: Single center, retrospective study based on immunoblotting panel analysis and patients clinical records. Pulmonary manifestations were sub-grouped in: 1) interstitial (alveolitis and/or fibrosis), 2) pulmonary artery systolic pressure (PASP) ≥40 mmHg plus interstitial pulmonary disease, and 3) isolated PASP≥40 mmHg (purely vascular). Results: Our scleroderma cohort included 200 patients, of which 137 had immunoblotting panels with anti-Ro52 reactivity analysis. The search was conducted between January 2010 and July 2011. The frequency of pulmonary manifestations in patients with positive anti-Ro52 antibodies was 67.7% (n=31), and 60% (n=24) in the negative anti-Ro52 group, showing no significant differences between groups (p=0.621). Still no significant differences were found when pulmonary manifestations were evaluated according to the subgroups (p=0.525). Sensitivity, specificity, positive and negative predictive values of anti-Ro52 reactivity for determining pulmonary involvement in scleroderma were low. Conclusion: No association was found between positive anti-Ro52 antibodies and pulmonary involvement in scleroderma. |
