We reassessed renal biopsy specimens from 116 patients with systemic lupus erythematosus and clinical manifestations of lupus nephritis to determine the contributions of the World Health Organization classification system, the activity and chronicity indexes of the National Institutes of Health scoring system, and various clinical parameters at the time of(More)
OBJECTIVE To determine the incidence and prevalence of ankylosing spondylitis (AS) over a prolonged period in the 2 northernmost counties of Norway, where HLA-B27 has a high prevalence in the population. METHODS We conducted a cohort study of all patients registered with a diagnosis of AS between 1960 and 1993 at the University Hospital of Northern(More)
Overexpression of B-lymphocyte activating factor (BAFF) results in arthritis, glomerulonephritis and autoantibody formation in mice, but its role in human autoimmune disease is less obvious. Serum BAFF levels in patients with systemic lupus erythematosus (SLE) (n=42) and rheumatoid arthritis (RA) (n=60) were related to levels of disease activity, anti-dsDNA(More)
BACKGROUND Combination therapy with cytotoxic drugs and corticosteroids reduces the risk for renal failure in patients with proliferative lupus nephritis (PLN), but uncertainty remains about the best mode of immunosuppression and its long-term effects. We report long-term results of combined azathioprine-prednisolone treatment for PLN, which has been the(More)
OBJECTIVE To determine survival, organ damage and predictors of these outcomes in a population-based, longitudinal cohort study of patients with Wegener's granulomatosis (WG). METHODS In a retrospective study, 56 WG patients (median age 50 yr) were followed for 56.5 months. Clinical and laboratory data, disease activity, organ involvement and the(More)
BACKGROUND Adult-onset Still's disease (AOSD) is considered a rare disease, but few data exist on the incidence and prevalence of AOSD. This study has analysed the epidemiology, disease presentation, and outcome of AOSD in a stable homogeneous population in Northern Norway. METHODS A retrospective cohort study of all AOSD patients registered in 1990-2000(More)
The classification of Spondyloarthritis (SpA) has been revised with the introduction of the ASAS classification criteria. Although this has best been described in ankylosing spondylitis and psoriatic arthritis, there are population studies evaluating the epidemiology of the different subgroups of SpA. In this paper, we present data on the incidence and(More)
PURPOSE To compare disease activity in patients with systemic lupus erythematosus (SLE) (1) before and after the onset of end-stage renal failure and (2) during hemodialysis and continuous ambulatory peritoneal dialysis (CAPD). PATIENTS AND METHODS Records of 55 patients with SLE currently being treated with dialysis were reviewed. Disease activity was(More)
Abnormal findings on salivary gland scintigraphy (SGS) are part of the classification criteria for Sjøgren’s syndrome (SS), but SGS is operator dependent and poorly standardised. We studied the use of quantitative data on the uptake, concentration and excretion of the four major salivary glands in the evaluation of sicca patients. During an initial clinical(More)
ANA testing by immunofluorescence technique (F-ANA) is nowadays still performed in much the same way as 45 years ago when the test was introduced. Due to its low specificity the F-ANA test has a poor predictive value for systemic autoimmune diseases and in addition has proven difficult to standardise. In the meantime, many of the nuclear and cytoplasmatic(More)
