The comparison in double immunodiffusion and western blotting methods of anti-SS-A/B antibodies in patients with Sj?gren's syndrome]

OBJECTIVE: To investigate the autoimmune responses against SS-A/B antigens by double immunodiffusion (DID) and western blotting (WB) in primary and secondary Sj?gren's syndrome (SS). PATIENTS: Forty-nine patients with primary SS (PSS), 28 patients with secondary SS (SSS) and control group that couldn't be diagnosed as SS were included in this study. RESULTS: In DID analysis, Anti-SS-A antibody was detected in 69% of PSS and 86% of SSS, and anti-SS-B antibody was found in 22% of PSS and 39% of SSS. No significant difference could be demonstrated between PSS and SSS concerning anti-SS-A/B antibodies. Conversely, WB studies disclosed evidences that 18% of PSS and no SSS reacted only with the 52 kD protein, and there was significantly increased in PSS. Sera reacting with the 60 kD antigen were found in 37% of PSS, 71% of SSS, and 75% of SSS with SLE, 63% of SSS with RA. The ratio of SSS, and SSS with SLE were particularly significantly higher than PSS. CONCLUSION: Our results revealed data that there are the difference of reactivity against SS-A/B antigens in WB between PSS and SSS.     

Selective decrease in antibody-dependent cell-mediated cytotoxicity in systemic lupus erythematosus and progressive systemic sclerosis.

With the use of two target cells (chicken erythrocytes and Chang cells), the antibody-dependent cell-mediated cytotoxicity (ADCMC) of peripheral blood mononuclear cells from patients with systemic lupus erythematosus (SLE) and progressive systemic sclerosis (PSS) was studied. Patients with active SLE had a significant reduction in ADCMC against Chang cells whereas cytotoxicity against chicken erythrocytes did not differ significantly from that of a control population. Similarly, a group of PSS patients with positive anti-DNP antibodies demonstrated a selective reduction in ADCMC against Chang cells. These findings support the concept that different effector cells mediate ADCMC against chicken erythrocytes and Chang cells, and indicate that in some patients with SLE and PSS there is a selective reduction or blockade of the ADCMC effector cell active against Chang cells.     

The Tie2 Receptor Antagonist Angiopoietin-2 in Systemic Lupus Erythematosus: Its Correlation with Various Disease Activity Parameters

Background: Systemic lupus erythematosus is one of the autoimmune diseases characterized by multisystem involvement associated with autoantibody and immune complex vasculitis along with endothelial cell damage. Objective: to study the possible role of Angiopoietin- 2 (Ang-2) as a recently highlighted inflammatory and angiogenic mediator in the pathogenesis of SLE and its correlation with the state of another inflammatory marker, P-Selectin, as well as with various markers of the disease activity. Patients and methods: The present study included 3 main groups: active SLE patients (group I), inactive SLE patients (group II) and healthy normal control subjects (group III). Groups I and II were subjected to disease activity assessment using the SLEDAI scoring system and measurement of plasma Ang-2 and P-Selectin by ELISA in addition to various laboratory investigations to assess disease activity as: Complete blood count, ESR, serum creatinine, C3, C4 and 24-h urinary proteins. Results: The mean level of Plasma Ang-2 and P-selectin showed a high significant increase in active group compared to inactive SLE patients and control subjects (p < 0.001).There was a significant positive correlation between Ang-2, P-Selectin, and each of SLEDAI score and 24-h urinary proteins in all SLE patients as well as in the active group, and Ang-2 was a significant independent marker for proteinuria. A significant negative correlation was found between Ang-2, P-Selectin and each of C3, C4. Ang-2 and P-Selectin showed a high sensitivity and specificity in the patients with SLE. Conclusion: Our study suggests that Ang-2 may be a more useful marker than P-Selectin, C3 and C4 in the assessment of disease activity.

Pathological significance and regulatory mechanism of lymphotoxin β receptor overexpression in T cells of patients with systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a typical autoimmune disease. Lymphotoxin β receptor (LTβR) signaling plays an important role in autoimmune inflammations. LTβR-Ig fusion protein, LTβR blocking agent, has been used to treat SLE, while its mechanism remains to be fully elucidated. In this study, to investigate the expression of LTβR in the T cells of SLE patients and its roles in the pathogenesis of SLE, we isolated the peripheral blood T cells of SLE patients and normal controls to detect expression of LTβR by flow cytometry and RNA assay. T cells were also stimulated with LIGHT, a ligand of LTβR, and then detected for their LTβR expressions and apoptosis by flow cytometry. Also, their expressions of inflammatory factors and receptors were determined by RNA assay. The results showed that LTβR positive cells were 22.75%
6.98% in CD3+ cells of SLE patients, while there were almost no LTβR positive cells in CD3+ cells of normal persons. Moreover, LTβR expression was remarkably higher in CD3, CD4 and CD8 positive T cells of active SLE patients than non/low active patients (all P < 0.05), and positively correlated with increased Ig level, decreased complement level and renal damage. Moreover, the stimulation of SLE T cells with LIGHT promoted higher expression of LTβR, IL-23R and IL-17A, and apoptosis of T cells. In conclusion, we demonstrated a high expression of LTβR in the T cells of SLE patients which may be associated with pathogenesis of SLE.
