Abstract:
Objectives To detect anti-basement membrane zone(BMZ)antibodies in systemic lupus ery-thematosus(SLE)patients and to explore its association with clinical manifestations.Methods Anti-BMZ anti-bodies were examined by indirect immunofluorescence in the sera of70patients with SLE.The correlation between anti-BMZ antibodies and clinical data of SLE was analyzed.Results Anti-BMZ antibodies could be found in the sera of about70%SLE patients,including IgG,IgM,IgA.They predominantly bound to the epidermis,but also bound to the dermis or both.The positive rate of anti-BMZ antibodies was significantly higher in patients with skin lesions than that of patients without skin lesions.There is no significant difference between the two groups in ac-tive and remission,kidney involvement,arthritis,alopecia,photoallergy,positive anti-dsDNA antibodies and the posi-tive rate of anti-BMZ antibodies.Conclusion Anti-BMZ antibodies presents in the sera of SLE patients with high positive rate.It is correlated with the development of skin lesions of SLE patients,but not with the activity of SLE,other clinical manifestations and anti-dsDNA antibodies.Anti-BMZ antibodies may be involved in the pathogenlic mechanism of the development of skin lesions in SLE patients.
