Systemic lupus erythematosus (SLE) is an inflammatory rheumatic disease characterized by production of autoantibodies and organ damage. Elevated levels of cytokines have been reported in SLE patients. In this study we have investigated the effect of proinflammatory cytokines (IL-6, TNF-α, and IL-1β) on clinical manifestations in 145 Indian SLE patients. One(More)
Systemic lupus erythematosus (SLE) is a prototype autoimmune disease, characterized by immune complex formation and systemic inflammation. Complement components such as C1q and mannose-binding lectin (MBL) play an important role in the clearance of immune complexes. Anti-C1q antibodies are associated with lupus nephritis and reduced levels of the complement(More)
BACKGROUND An autoimmune cause and related immunological alterations resulting in recurrent spontaneous abortion (RSA) have been suggested in patients with unknown etiology. MATERIALS AND METHODS This study evaluated the autoantibody profile and other immunological parameters among RSA patients and normal pregnant women from Mumbai western India. Fifty(More)
Systemic lupus erythematosus (SLE) is characterized by over production of autoantibodies. C-reactive protein (CRP) is a phylogenetically highly conserved plasma protein that participates in the systemic response to inflammation. Anti-CRP antibodies might have biological functions of pathogenetic interest in SLE. We evaluated anti-CRP antibodies in Indian(More)
BACKGROUND & OBJECTIVES Receptors for the Fc fragment of immunoglobulin G (Fc γ Rs) represent the link between humoral and cellular immune responses. Polymorphisms in Fc γ Rs have been identified as genetic factors influencing susceptibility to various autoimmune diseases. This study was aimed to identify Fc γ R IIB genotypes in Indian systemic lupus(More)
To identify Fc γ RIIA genotypes in Systemic Lupus Erythematosus (SLE) patients and their association with anti-C1q antibodies. Methods. Fc γ RIIA genotyping was done in eighty Indian SLE patients and eighty healthy controls using allele-specific PCR. Anti-C1q antibodies were measured by ELISA. Results. LN patients showed higher SLEDAI (6-32) as compared to(More)
Systemic lupus erythematosus (SLE) is an autoimmune disorder affecting multiple organ systems. It is characterized by the presence of autoantibodies reactive against various self-antigens. Susceptibility to SLE is found to be associated with many major histocompatibility complex (MHC) and non-MHC genes, one of which is APO-1/Fas gene, which is present on(More)
BACKGROUND & OBJECTIVES Systemic lupus erythematosus (SLE) is a prototypical autoimmune disease characterized by production of autoantibodies. Mannose binding lectin (MBL) is an important element of the innate defense system. t0 he present study was undertaken to determine whether variant alleles in MBL2 gene were associated with disease severity in SLE(More)
Receptors for the Fc domains of IgG (Fc gamma R) play a critical role in linking humoral and cellular immune responses. The various Fc gamma R genes may contribute to differences in infectious and immune related diseases in various ethnic populations. Polymorphisms of Fc gamma R mainly Fc gamma R IIA, IIB, IIIA, IIIB have been identified as genetic factors(More)
