In this retrospective study 103 serum samples from 16 females with systemic lupus erythematosus (SLE), obtained during a mean follow-up time of 2 years, were investigated for the presence of anti-denatured [single-stranded (ss)] DNA antibodies of the IgG, IgM, and IgA classes. The anti-ssDNA antibodies were determined by an enzyme-linked immunosorbent assay (ELISA), and the results were expressed in three ways: as units derived from a single serum dilution and as two parameters,E andA, calculated from the dose-response curve,E being an estimate of the effective amount of antibodies andA a function of the reaction constant between the antigen and the antibody. The simultaneous occurrence of anti-ssDNA antibodies of all three immunoglobulin classes was seen most often in the patients with the shortest duration of the disease. Clinically active disease was found to correlate with high reaction constants of the IgA anti-ssDNA antibodies. There was also an association between the IgA anti-ssDNA antibody levels and the presence of nephritis. Great fluctuations in the amounts of effective antibodies of the IgG class were seen in seven patients, in six of whom changes in the disease activity also were seen. Changes in the disease activity were unaccompanied by fluctuations in the IgG anti-ssDNA levels in four patients; two of these patients were positive for antibodies against extractable nuclear antigens. We conclude that it is of value to express the results of the anti-ssDNA ELISA as a function of the dose-response curve when monitoring patients with SLE and that immunoglobulin class-specific determinations of anti-ssDNA antibodies may provide information about the disease activity in many patients with SLE. 相似文献

Neutrophils purified from peripheral blood of patients with the Shwachman syndrome show enhanced chemiluminescence (CL) and depressed chemotaxis. Here we present data showing that the increased CL response can be demonstrated by using a whole blood CL assay. This assay is well-suited for studies in infants, because the blood sample volumes needed are small. Increase in CL was most distinct in the initial (1 min) activation induced by N-formyl-methionyl-leucyl-phenylalanine. The 1-min response is considered to derive from extracellular production of oxygen radicals. Such an extracellular oxygen radical production may render the patients susceptible to undue oxidant stress. We therefore treated the patients with two antioxidants, thiamine and -tocopherol, for 3 months. This supplementation, however, failed to exert any significant effect on either whole blood CL or migration of the patients' neutrophils under agarose. 相似文献

Abstract Maria Pachalska's approach to aphasia rehabilitation is from a holistic perspective. Traditionally, aphasia therapists have tried to promote communicative ability using several methods. Pachalska has combined the most important approaches and created a model which she calls the Complex Aphasia Rehabilitation Model (CARM). She offers this model as an example of a holistic approach to aphasia rehabilitation. It stresses the importance of taking into account both psychological and social factors in aphasia rehabilitation. 相似文献

Synovial fluid cells in Reiter's syndrome were studied by cell subset specific monoclonal antibodies and avidin-biotin-peroxidase complex staining. Mean leucocyte count was 9842/mm3 (9.842 X 10(9)/l), and 71% of all cells were polymorphonuclear leucocytes. 26 +/- 11 (SEM)% and 47 +/- 5% of all mononuclear cells in synovial fluid were M1+ monocytes and Ia+ cells, respectively. T11+ T lymphocyte was the predominant synovial fluid mononuclear cell (61 +/- 8%) but, in contrast to the inflammatory joint effusions in rheumatoid arthritis, T4+ cells clearly outnumbered T8+ cells in Reiter's syndrome. Thus the synovial fluid in Reiter's syndrome contains the immunocompetent and accessory cells required for immune response, which in fact is activated as suggested by lymphocyte Ia expression. Furthermore, in contrast with rheumatoid arthritis inducer/helper cells with T4 phenotype seem to be involved preferentially in the local pathogenetic mechanisms in Reiter's syndrome. 相似文献

Outcomes of a multicentre randomised clinical trial of etanercept to treat ankylosing spondylitis 总被引:5,自引:0,他引:5 下载免费PDF全文

OBJECTIVE: A double blind, randomised, placebo controlled study to evaluate the safety and efficacy of etanercept to treat adult patients with ankylosing spondylitis (AS). METHODS: Adult patients with AS at 14 European sites were randomly assigned to 25 mg injections of etanercept or placebo twice weekly for 12 weeks. The primary efficacy end point was an improvement of at least 20% in patient reported symptoms, based on the multicomponent Assessments in Ankylosing Spondylitis (ASAS) response criteria (ASAS 20). Secondary end points included ASAS 50 and ASAS 70 responses and improved scores on individual components of ASAS, the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), acute phase reactants, and spinal mobility tests. Safety was evaluated during scheduled visits. RESULTS: Of 84 patients enrolled, 45 received etanercept and 39 received placebo. Significantly more etanercept patients than placebo patients responded at the ASAS 20 level as early as week 2, and sustained differences were evident up to week 12. Significantly more etanercept patients reported ASAS 50 responses at all times and ASAS 70 responses at weeks 2, 4, and 8; reported lower composite and fatigue BASDAI scores; had lower acute phase reactant levels; and had improved spinal flexion. Etanercept was well tolerated. Most adverse events were mild to moderate; the only between-group difference was injection site reactions, which occurred significantly more often in etanercept patients. CONCLUSIONS: Etanercept is a well tolerated and effective treatment for reducing clinical symptoms and signs of AS. 相似文献

OBJECTIVE: To ascertain the occurrence and characteristics of uveitis in sibling pairs affected with juvenile idiopathic arthritis (JIA). METHODS: The sibling series comprised 80 JIA patients from 37 families with two or three JIA children, seen at the paediatric department of the Rheumatism Foundation Hospital in Heinola, Finland. An ophthalmologist examined the children for uveitis two to four times a year and the course of the condition was recorded during the follow-up. RESULTS: Uveitis was diagnosed in 21 of the 80 patients (26%). Three pairs (3.4 pairs expected) were concordant for the presence of asymptomatic uveitis. Two patients with enthesitis-related arthritis had acute unilateral uveitis. Among the remaining cases, uveitis was chronic and continuously active at the end of follow-up in 13 instances, but in spite of this only one patient had impaired vision. HLA allele B27 occurred more frequently in patients with uveitis than in those without uveitis (52 vs 30%, P=0.073) and all six subjects in the pairs concordant for chronic uveitis carried this allele. CONCLUSIONS: The observed concordance rate for uveitis did not differ from that expected. Although the uveitis was chronic in most instances, its course was usually mild. 相似文献

OBJECTIVE: The rarity of reports on extended multiplex families points out that the genetic component in juvenile idiopathic arthritis (JIA) might not be particularly strong. Our objective was to determine the frequency of chronic inflammatory rheumatic diseases among the parents who had two or more offspring affected by JIA. METHODS: During the last 17 years patients with JIA treated at the Rheumatism Foundation Hospital in Heinola and their parents have been systematically asked about the familial occurrence of rheumatic diseases. A total of 45 families with more than one sibling affected by JIA were found among about 2,300 JIA cases. In these "multicase families", 9 parents from 8 families also had a diagnosis of chronic inflammatory rheumatic disease. Their case histories were studied. RESULTS: Four of the parents had had JIA (one subsequently developed ankylosing spondylitis), and 4 had rheumatoid factor-negative chronic arthritis (one had also had chronic iritis since the age of 10, resembling that seen in JIA). Three of them had features of JIA and only one met the classification criteria for rheumatoid arthritis. One had ankylosing spondylitis. CONCLUSIONS: Since the expected number of JIA cases among the 90 parents was about 0.2, there was drastic increase in JIA frequency among the parents in families with multiple offspring also affected by JIA. These results suggest that JIA susceptibility genes may likely be clustered in these families. 相似文献
