Systemic lupus erythematosus (SLE) is a prototypical autoimmune disease characterized by production of autoantibodies and complex genetic inheritance. In a genome-wide scan using 85,042 SNPs, we identified an association between SLE and a nonsynonymous substitution (rs10516487, R61H) in the B-cell scaffold protein with ankyrin repeats gene, BANK1. We(More)
OBJECTIVE To determine whether specific isoforms of IRF5 are transcribed in patients with systemic lupus erythematosus (SLE) who have risk genotypes in the exon 1B donor splice site at single-nucleotide polymorphism (SNP) no. rs2004640. METHODS Peripheral blood mononuclear cells were obtained from SLE patients and healthy controls from Argentina, Spain,(More)
The association between polymorphisms in the programmed death (PD-1) gene and susceptibility to systemic lupus erythematosus (SLE) was determined using genomic DNA, isolated from a population-based cohort of 95 SLE patients and 155 healthy controls. Polymorphisms in the complete PD-1 gene except the large intron 1 were detected by sequencing. Furthermore,(More)
The serum concentration of YKL-40, a matrix protein of specific granules in neutrophils, was determined by RIA in 90 patients hospitalized with pneumonia of suspected bacterial origin. Of these, 64 were followed prospectively during antibiotic treatment with blood samples taken on day 0 (on admission and the start of treatment) and on days 1, 3, 5, 7, 10,(More)
OBJECTIVE To identify predictors of radiographic progression in a 2-year randomised, double-blind, clinical study (CIMESTRA) of patients with early rheumatoid arthritis (RA). METHODS Patients with early RA (n = 130) were treated with methotrexate, intra-articular betamethasone and ciclosporin/placebo-ciclosporin. Baseline magnetic resonance imaging (MRI)(More)
This study describes the importance of mannose-binding lectin (MBL) variant alleles for systemic lupus erythematosus (SLE) and accompanying infections in a population-based cohort. MBL alleles were determined in 99 SLE patients recruited from a representative Danish region. Patients were classified according to the 1982 revised ACR criteria as definite SLE(More)
A Danish multicentre study was undertaken of the manifestations, infections, thrombotic events, survival and predictive factors of survival in 513 Danish patients with systemic lupus erythematosus (SLE) according to the 1982 classification criteria of the American College of Rheumatology. The mean duration of follow-up was 8.2 years from diagnosis and 12.8(More)
SP-D is a lectin involved in the first line of defense against microorganisms. It is primarily found in the lung but also at extrapulmonary sites and in the circulation. An immunoassay for the quantification of SP-D in serum was established and the SP-D concentration was measured in consecutive blood samples from 61 patients hospitalized for(More)
Systemic lupus erythematosus (SLE) is an autoimmune disease mainly mediated by the deposit of immune complexes and defects in T lymphocytes and antigen-presenting cells along with a high production of T-helper 2 cytokines. A tolerance-inducible function of nonclassical class Ib human leukocyte antigen (HLA)-G molecule in innate and adaptive cellular(More)
Innate immune system abnormalities, e.g., mannan-binding lectin (MBL) genotype variants, have been demonstrated to modify the disease course of rheumatoid arthritis (RA). Surfactant protein D (SP-D) shares important structural and functional properties with MBL suggesting that SP-D may be an additional RA disease modifier. The Met11Thr polymorphism in the(More)
