Systemic lupus erythematosus is a complex and potentially fatal autoimmune disease, characterized by autoantibody production and multi-organ damage. By a genome-wide association study (320 patients and 1,500 controls) and subsequent replication altogether involving a total of 3,300 Asian SLE patients from Hong Kong, Mainland China, and Thailand, as well as(More)
BACKGROUND The combination of cyclophosphamide and prednisolone is effective for the treatment of severe lupus nephritis but has serious adverse effects. Whether mycophenolate mofetil can be substituted for cyclophosphamide is not known. METHODS In 42 patients with diffuse proliferative lupus nephritis we compared the efficacy and side effects of a(More)
In this study, we compared the association of several newly discovered susceptibility genes for systemic lupus erythematosus (SLE) between populations of European origin and two Asian populations. Using 910 SLE patients and 1440 healthy controls from Chinese living in Hong Kong, and 278 SLE patients and 383 controls in Thailand, we studied association of(More)
The aims were to study the gender differences in clinical manifestations, disease course and organ damage in systemic lupus erythematosus (SLE). Clinical manifestations, autoantibody profile, relapses and damage scores were obtained from 51 Chinese males with SLE and compared with 201 consecutive female SLE controls. Fifty-one males were identified among(More)
OBJECTIVE The incidence and clinical significance of anti-cyclic citrullinated peptide (CCP) antibodies in a cohort of Chinese patients with juvenile idiopathic arthritis (JIA) and adults with rheumatoid arthritis (RA) were studied. METHODS Anti-CCP antibodies were determined by enzyme-linked immunosorbent assay (ELISA) in 59 patients with JIA, 129 adult(More)
Systemic lupus erythematosus (SLE) is a prototypic autoimmune disease with complex genetic inheritance. Recently, single nucleotide polymorphisms (SNPs) in BANK1 and TNFSF4 have been shown to be associated with SLE in Caucasian populations, but it is not known whether they are also involved in the disease in other ethnic groups. Recent data from our(More)
OBJECTIVE To study the predictive factors for avascular necrosis (AVN) of bone in patients with systemic lupus erythematosus (SLE). METHOD The records of 38 SLE patients who developed clinically apparent AVN during the course of their disease were reviewed. Information on clinical presentation, corticosteroid usage and autoantibody profiles was obtained,(More)
OBJECTIVE To determine the incidence of ovarian failure after cyclophosphamide (CYC) treatment for systemic lupus erythematosus (SLE) and to identify the risk factors for this complication. METHODS The records of 70 premenopausal female SLE patients treated with CYC were reviewed retrospectively. Information on demographic features, autoantibody profiles,(More)
OBJECTIVE To study the neuropsychiatric (NP) manifestations in a large cohort of southern Chinese patients with systemic lupus erythematosus (SLE) according to the new 1999 American College of Rheumatology (ACR) case definitions and their clinical associations. METHOD Patients with SLE who were followed from 1984 to 2000 were retrospectively reviewed.(More)
Systemic lupus erythematosus (SLE) is a prototype autoimmune disease with a strong genetic involvement and ethnic differences. Susceptibility genes identified so far only explain a small portion of the genetic heritability of SLE, suggesting that many more loci are yet to be uncovered for this disease. In this study, we performed a meta-analysis of(More)
