2856511 Enhanced oxidative response of polymorphonuclear leukocytes from synovial fluids of patien 1988 Polymorphonuclear leukocytes (PMN) isolated from the synovial fluid (SF) of patients with rheumatoid arthritis (RA) exhibited an enhanced oxidative response to heat aggregated IgG (Hagg) and N-formyl-methionyl-leucyl-phenylalanine (FMLP) as compared with either autologous or normal blood PMN. Normal blood PMN pretreated with synovial fluid showed a significantly increased response to FMLP which was unaffected by prior dialysis of SF. The degree of enhancement produced varied between SF's and was dependent on the period for which cells were incubated and on the concentration of SF used. In contrast there was no enhancement of the oxidative response when Hagg was used as a stimulus. Indeed, SF produced a dose dependent inhibition of Hagg stimulated superoxide production. These observations suggest that SF's from patients with RA contain factors which both enhance and inhibit the oxidative response of PMN depending on the subsequent stimulus.
1720991 Monoclonal antibody treatment in rheumatoid arthritis: the clinical and immunological effe 1991 Dec Six patients with rheumatoid arthritis were treated with a CD7 mouse monoclonal antibody, RFT2, daily for 15 days. Only two patients had a significant improvement in clinical disease activity which lasted 7-14 days. No serious adverse effects occurred although all patients developed antibodies against mouse immunoglobulin. During treatment T-lymphocyte numbers decreased and T-lymphocyte CD7 expression was absent in all but one patient.
2179550 Reversible nephrotoxicity of cyclosporine in rheumatoid arthritis. 1990 Jan Irreversible nephrotoxicity has limited the use of cyclosporine in rheumatoid arthritis (RA). In a randomized clinical trial we compared 26 weeks of cyclosporine (5 mg/kg) and D-penicillamine (250 mg) treatment in 92 patients with RA with a serum creatinine less than 100 mumol/l. We adjusted the starting dose according to clinical response and side effects. During cyclosporine treatment the serum creatinine increased by median 15% (p less than 0.0001 vs baseline), quickly reversible after stopping (median followup: 1.6 years). Six patients stopped cyclosporine prematurely because of nephrotoxicity. In the D-penicillamine group the values remained at baseline.
3236296 The presence of a myeloid cell population showing strong reactivity with monoclonal antibo 1988 Nov The presence of a specific type of cell, highly expressing difucosyl type 2 chain (dimeric Lex; FH-4 antigen), was found in the epiphyseal bone marrow cells of affected joints from patients with active severe rheumatoid arthritis (RA). The antigen was defined by monoclonal antibody FH-4 which was previously found to be directed to the oncofetal marker. The FH-4(+) cell population was identified as myeloid cell lineage with usual morphology specifically found in bone marrow of patients with severe RA, but is virtually absent in the same cell fraction of patients with osteoarthritis, infectious arthritis, and from normal adult subjects.
2290162 Fibromyalgia in human immunodeficiency virus infection. 1990 Sep Tenderness was assessed by point count and by scored palpation in 51 patients with human immunodeficiency virus (HIV) infection as well as 51 patients with rheumatoid arthritis (RA) and 50 patients with psoriatic arthritis (PsA). Fifteen of 51 (29%) patients with HIV infection met criteria for fibromyalgia, based on the presence of 10 tender (of 14) "fibrositic" points. Similar results were observed among patients with PsA (24%). The prevalence of fibromyalgia was higher among patients with RA (57%). Patients with HIV and PsA were less tender than patients with RA. Fibromyalgia in patients with HIV was significantly associated with myalgia and arthralgia, but not with age, duration of HIV infection, stage of HIV disease, or zidovudine therapy.
2259839 Lymphocyte infiltration and the synthesis of IgM and IgA rheumatoid factors by rheumatoid 1990 IgM and IgA rheumatoid factor (RF) synthesis by synovial membrane mononuclear cells was measured in 14 patients with rheumatoid arthritis (RA). The results were compared with blood mononuclear cell cultures and correlated with the intensity of lymphocyte infiltration of the synovium. IgM RF was produced by all synovial cultures compared with 56% of blood cultures; IgA RF was produced by 86% of synovial cultures and by 21% of blood cultures. A correlation was observed between synovial IgM RF synthesis, but not IgA RF synthesis, and the intensity of T cell and B cell infiltration of the synovial membrane.
2204217 [Long-term drug treatment of chronic polyarthritis: current status and perspectives]. 1990 Jun 30 The therapeutic repertoire for the treatment of rheumatoid arthritis has been expanded to new disease-modifying antirheumatic drugs (DMARDs), like Auranofine, Sulfasalazine, and Methotrexate. Rheumatoid arthritis is not only a highly disabling disease but is now recognized to be related with increased mortality. Therefore, the aim of therapeutic strategies is the early induction of remission. The strategy for treatment of rheumatoid arthritis should be based on an analysis of the individual risk of a patient to develop severe illness. A concept of "risk-oriented DMARD-therapy" of rheumatoid arthritis is proposed.
1855813 [Three cases of chronic polyarthritis after silicon implantation (breast augmentation): ca 1991 Apr We describe three women with rheumatoid arthritis after augmentation mammoplasty with silicone implants. The possibility for a causal relationship between silicone implantation and arthritis as examples of a "human adjuvant disease" is discussed.
1842206 Comparison of four articular indices for use in clinical trials in rheumatoid arthritis: p 1991 May Using a Latin square design, 4 patients were examined by 4 rheumatologists. Joints were scored for tenderness and inflammation. The Ritchie, the index of the American Rheumatism Association (ARA), the Hart modified Ritchie and a simplified Lansbury index were calculated from the raw data. The results suggest that an articular index consisting of a simple count of tender joints (Hart modified Ritchie) or a simple count of tender or swollen joints (ARA index) are the most reproducible with multiple observers. We suggest that these indices would be most appropriate for multicenter clinical trials.
1701997 Association of HLA-Dw16 with rheumatoid arthritis in Yakima Indians. Further evidence for 1991 Jan Rheumatoid arthritis (RA) is prevalent in Yakima Indians, a Native American tribe. HLA-DR4, the HLA specificity commonly associated with RA in Caucasians, is rare among the Yakima. Using a specific oligonucleotide probe that recognizes DR4 nucleotide sequences associated with RA, a rare HLA-Dw16 gene was identified in 83% of Yakima patients with RA and in 60% of Yakima control subjects. This shared sequence encodes a discrete class II epitope that is highly correlated with RA in both DR4 positive and DR4 negative individuals.
2787185 Effects of aminobisphosphonate infusion on biochemical indices of bone metabolism in rheum 1989 Aug In a phase 1 study, seven patients with classical rheumatoid arthritis were treated with intravenous 3-amino-1-hydroxypropylidene-1-1-bisphosphonate (APD). Following this treatment, bone resorption as measured by fasting urine calcium/creatinine and hydroxyproline/creatinine ratios, was reduced. This was sustained for 6 months in only three patients. Elevations of these ratios often coincided with flares of active arthritis in the remaining four patients. Bone turnover as measured by serum osteocalcin levels was reduced in all patients but serum alkaline phosphatase levels remained unchanged. There was no consistent improvement in clinical indices of disease activity.
2053307 [Plasma iron levels in patients with rheumatoid arthritis]. 1991 Apr In 50 patients with confirmed or classical rheumatoid arthritis the serum iron level (FeS) was examined (in some repeatedly), the total number of examinations being 82. In 51.1% reduced values were recorded. In 27 subjects of the group the total iron binding capacity was assessed. In none of the patients reduced values were found, in 24 the values were at the upper borderline of normal values and in one instance the value was elevated. In 13 patients with a low FeS with a normal or elevated total iron binding capacity Ferronat Retard was administered. The FeS level reached relatively rapidly normal values which in the author's opinion is rather a manifestation of receding activity of rheumatoid arthritis. They consider administration of iron preparations even in patients with a relatively high total iron binding capacity problematical, except when there is justified suspicion of iron ion losses via the gastrointestinal tract or in malnutrition. Iron administration did not cause deterioration of the rheumatic process.
2558409 Pathogenesis of lentivirus-induced arthritis. A review. 1989 While it has been known for some years that there is an association between lentiviruses and slowly progressive joint diseases in ruminants, the realization that the human immunodeficiency virus, the cause of AIDS, is a lentivirus has made this group of virus the focus of a considerable research effort. The manifestations of lentivirus infection in animals are discussed and reference is made to the possibility of using them as models for human rheumatoid arthritis and for AIDS.
1765972 A study of the longterm efficacy and toxicity of cyclosporine A in rheumatoid arthritis. 1991 Oct We determined the longterm efficacy and toxicity of cyclosporine A in rheumatoid arthritis (RA) in an open clinical trial, at a single centre, outpatient rheumatology clinic. The initial dose was 5 mg/kg/day increased to 10 mg/kg/day with adjustments for toxicity and plasma cyclosporine A levels. We measured efficacy by the Ritchie articular index, pain and function on a 10 cm visual analog scale, C-reactive protein (CRP) and erythrocyte sedimentation rate. Toxicity was evaluated by patient reports, serum creatinine, cyclosporine A levels and liver function tests. Median treatment duration was 29 months (16.5-38). At 24 months median reduction in Ritchie articular index was 50% (9-79); pain: 49% (21-77), with a 50% (4-76) improvement in function; and CRP fell by 72.5% (22-87). The main side effect was a 40% (27-47) decline in estimated creatinine clearance. We conclude that cyclosporine A at doses below 5 mg/kg/day is associated with clinically significant improvements in indices of disease activity in RA. Renal dysfunction was the most frequent side effect.
1969007 [Surgical correction of an unusual forefoot deformity in a patient with rheumatoid arthrit 1990 Authors report on a foot deformity, that can be considered as literary rarity and on its operative treatment. The alteration described was unusual because of the flexion contracture beside the valgus position of the hallux. The aim of the operative procedure described was the correction of the position of the hallux and the improvement of the metatarsalgia, causing nearly complete inability of walk.
1824546 Capitellocondylar total elbow replacement for rheumatoid arthritis. 1991 Apr In all, 23 capitellocondylar total elbow replacements were performed in 18 patients with rheumatoid arthritis. Follow-up was for a mean (range) of 3 (1.5-5) years. Pain relief was achieved in all patients and the postoperative range of movement showed an improvement in all directions. No evidence of radiological loosening has been seen. Complications consisted of a transient ulnar nerve palsy in 15 elbows (65%) and a permanent ulnar nerve palsy in one elbow (4%). In two elbows there was delayed wound healing.
2101412 A case of rheumatoid arthritis which developed after recovery from adult respiratory distr 1990 Nov A 53-year-old previously healthy woman suddenly developed adult respiratory distress syndrome (ARDS) of unknown etiology. High-dose corticosteroid pulse therapy and artificial ventilation were started immediately and she dramatically responded to the treatment. However, soon after recovery from ARDS, she developed typical rheumatoid arthritis (RA). Although no apparent relationship between RA and ARDS was clear, this case is quite suggestive in the consideration of the etiology of ARDS.
3337934 Determinants of disability in rheumatoid arthritis. 1988 Feb The longitudinal determinants of disability were studied in a group of 30 patients with rheumatoid arthritis over a 3-year period. The patients were investigated on two occasions using quantitative measures of disease activity and disability as well as a series of reliable psychometric instruments. Both longitudinal and cross-sectional data analyses were performed. Psychological factors consistently predicted more of the variance of disability than disease activity. These factors were associated with the tendency to deny the emotional dilemmas caused by having a chronic illness, difficulty in accepting doctors' reassurances and clinical depression. Such psychological variables required specific attention in rehabilitation programmes.
3560090 Patient, observer and instrument variation in the measurement of strength of shoulder abdu 1986 Dec We describe the use of a modified sphygmomanometer to measure the strength of shoulder abductor muscles. Using a 5 x 5 Greco-Latin square design we compared the measurements of 5 physical therapists taken on 5 patients with rheumatoid arthritis with 2 cuff adaptations. The design variables explained 96.4% of the pressure readings, with patients accounting for 76.6%. There was no significant variation due to order of testing, cuff preparations or observers. The method is simple, portable, inexpensive, comfortable and safe to use. It can also be applied to 26 different muscle groups.
2784307 Alpha 1 antitrypsin (PI) phenotypes in two rheumatic diseases: a reappraisal of the associ 1989 Jan alpha 1 Antitrypsin phenotypes were determined by isoelectric focusing in 225 adult white patients with rheumatoid arthritis (RA), 60 patients with severe rheumatoid arthritis (grade III and IV), 17 sibling pairs--HLA identical but discordant for rheumatoid arthritis, and 122 random patients with Sjögren's syndrome. No significant increase in non-M phenotypes was found in either of the groups of patients with RA, but the association between M subvariants was striking. There was a significant increase in M1M2 phenotype and M2 allotype in both the RA and severe RA groups. This increase in M1M2 was also supported by DR4 positive patients with RA compared with DR4 positive siblings without RA. No apparent association of variant phenotype was found in four subgroups of patients with Sjögren's syndrome.
