Severity of dry eye syndrome was determined by corneal sensation (KSen), superficial punctuate Haloperidol D4′ keratopathy (SPK), Schirmer-I test (Schirmer), and tear film break-up time (TBUT). The autoantibodies and the dry eye parameters in each group were tested using the 2 2 test or the MannCWhitney test for normally distributed or skewed data, respectively. The anti-dsDNA showed significant correlations with KSen (= 0.042) but not TBUT. The C3 showed significant correlations with KSen Haloperidol D4′ (= 0.014) but not TBUT. No correlations of dry eye parameters were observed between C4, ESR, and ANA.

Dry vision parameters and the presence of different autoantibodies in each group were tested using the 2 2 test or the MannCWhitney test for normally distributed or skewed data respectively. Normality of the data was tested using Spearman’s correlation test. Analyses were performed using SPSS for Windows version 12.0 (SPSS, Inc., Chicago, IL).

Open in a separate Haloperidol D4′ window 4.?Conversation Due to the increased evidences that dry eye syndrome in SLE patients may not be as much associated with sSS,[18,23,25] we investigated the SLE patients who were anti-SSA/SSB negative without any oral symptoms to rule out sSS. The major finding of this study was that the severity of dry eye syndrome in these patients was strongly correlated with anti-dsDNA and C3 but not with C4, ESR, and ANA (Fig. ?(Fig.11).

Mouse monoclonal to CD34.D34 reacts with CD34 molecule, a 105-120 kDa heavily O-glycosylated transmembrane glycoprotein expressed on hematopoietic progenitor cells, vascular endothelium and some tissue fibroblasts. The intracellular chain of the CD34 antigen is a target for phosphorylation by activated protein kinase C suggesting that CD34 may play a role in signal transduction. CD34 may play a role in adhesion of specific antigens to endothelium.

Anti-dsDNA is regarded as highly specific for SLE because it has strong positive correlation with the commorbidities of SLE,[3C5,27C29] but its association with dry eye syndrome has not been clearly recognized. Our study found that anti-dsDNA was significantly correlated with KSen (= 0.042). Interestingly, Menendez et al[30] found that SLE patients with positive anti-SSA experienced lower levels of anti-dsDNA, but the results were not statistically significant. To the best of our knowledge, our study was the first to show that SLE patients with dry eye syndrome and unfavorable anti-SSA were associated with high levels of anti-dsDNA. And as anti-dsDNA is usually rarely found in other autoimmune diseases,[31] our result offered a new perspective on the cause of dry eye. Previous studies have already shown that anti-dsDNA was effective in monitoring lupus activity and that the rise of anti-dsDNA level could predict SLE relapse.[4,5] However, the role of anti-dsDNA around the pathogenesis of dry vision in SLE, or even kidney injury, remains to be elucidated. Likewise, the pathogenesis of dry vision in Sjogren syndrome is still ambiguous, but the targeting of glandular epithelial cells of the lacrimal glands by lymphocytes is usually thought to be one.
