| 61224 | Tolmetin sodium, a new anti-arthritis drug: double-blind and long-term studies. | 1976 Oct | The effectiveness of tolmetin sodium in the treatment of rheumatoid arthritis was evaluated by: 1) a 12-week, double-blind study with a dosage range of 800-1600 mg daily; and 2) an open 2-year study with a dosage range of 400-2400 mg daily. The double-blind study involved 14 patients (7 tolmetin sodium, 7 placebo), and the long-term study involved 24 patients. At frequent intervals, evaluations were made of joint pain, swelling, stiffness and inflammation; grip strength; walking time; and subjective well-being. Various laboratory tests were also performed. In the double-blind study, tolmetin sodium proved superior to placebo and produced moderate improvement. In the long-term study, 5 patients improved markedly, 14 moderately, and 3 minimally. Severe side effefts were notably absent. Some mild side effects occurred but they were transient and did not interfere with therapy. Tolmetin sodium seems effective and safe in the management of rheumatoid arthritis. | |
| 942502 | Serum immunoglobulins, rheumatoid factor, and pneumoconiosis in coal miners with rheumatoi | 1976 Jul | The occurrence and severity of pneumoconiosis were studied in 100 coal miners with rheumatoid arthritis (RA) and compared to findings in a geographically relevant survey of coal workers' pneumoconiosis. Contrary to European reports, miners with RA were not found to have an excessive frequency or severity of pneumoconiosis. In 55 of these men, serum immunoglobulin levels and rheumatoid factor were compared with data from matched RA patients with no history of silica exposure. The immunochemical results were unrelated to the stage of pneumoconiosis, nor did they differ from those in the control group. | |
| 6986118 | A syndrome of multiple immune autoreactivity. A breakdown in immune regulation. | 1980 Jan | The clinical findings of pemphigus vulgaris, rheumatoid arthritis, and Sjögren's syndrome were found in a patient displaying immunological abnormalities found in pemphigus vulgaris, systemic lupus erythematosus, rheumatoid arthritis, and Hashimoto's thyroiditis. Some of the antigen-antibody systems detected in this case were further identified. Our patient may be an example of severe failure in immune regulation. | |
| 1184638 | Arthroplasty of both hips and both knees in rheumatoid arthritis. | 1975 Oct | Eleven patients with rheumatoid arthritis underwent total joint replacement of both hips and both knees (four-joint arthroplasty). All patients had increased function and decreased pain. Severe rheumatoid arthritis in both hips and knees does not preclude a satisfactory result after replacement arthroplasty. | |
| 6707061 | The development of an unconstrained elbow arthroplasty. A clinical review. | 1984 Mar | This paper describes the development, operative technique and results of an unconstrained total elbow arthroplasty. Forty-seven elbow replacements were carried out in 44 patients between 1974 and 1982. There was a high rate of loosening in the early condylar replacements. The results in patients with post-traumatic arthritis were poor. The later design employs an ulnar stem, with a humeral stem if the distal humeral bone stock is poor. When used in carefully selected patients with rheumatoid arthritis, pain is reduced significantly, stability and movement are preserved and function is improved. | |
| 3901871 | On the structural and physiological basis of the influence of exercise, movement and immob | 1985 | In inflammatory joint diseases the protein concentration often is high in the synovial fluid and, in rheumatoid arthritis at least, probably also in the extra-articular connective tissue. This alters the Starling equilibrium. Peculiarities of the circulation of blood and lymph in articular units and basic physiological principles might explain not only why this readily manifests as joint effusions, but also the influence of exercise, movement, immobilization and posture on the activity of non-bacterial synovitides. | |
| 6346870 | Hydroxychloroquine sulfate in rheumatoid arthritis: long-term response rate and predictive | 1983 Jul 18 | Review of the records of 108 patients with rheumatoid arthritis who were treated with hydroxychloroquine sulfate for at least six months revealed that 63 percent responded: 12 percent achieved complete remission (no joint pain or tenderness, two or less joints with trace swelling); 14 percent showed a 75 percent response (75 percent or greater reduction in active joint count and 50 percent or greater reduction in morning stiffness); and 37 percent had between 30 percent (30 percent or greater reduction in active joint count and morning stiffness) and 75 percent response. Once response was obtained, flare-up of rheumatoid arthritis was uncommon. Only two of 108 patients developed retinopathy (subclinical); it resolved with drug discontinuation and did not cause visual deficits. Better grip strength and radiographs showing little articular damage at baseline might predict response to treatment with hydroxychloroquine. However, even though early disease may be more responsive, long-term rheumatoid arthritis does not preclude a good response to hydroxychloroquine. | |
| 1084751 | Obstructive pulmonary disease in rheumatoid arthritis. | 1976 May | Twenty-six of 43 patients (60.5%) with classic rheumatoid arthritis (RA) participating in a controlled, prospective study were found to have maximal midexpiratory flow rates (MMEFs) suggestive of obstructive pulmonary disease. Cigarette smokers with RA had significantly lower MMEFs than either nonsmokers with RA or smokers with degenerative joint disease. There was an increased prevalence of the Pi phenotype MS among the RA patients. Interstitial fibrosis, tobacco smoking, and protease inhibitor deficiencies were all significant factors in producing airway obstruction in patients with RA. | |
| 728373 | Haem biosynthesis in rheumatoid disease. | 1978 Dec | The activities in blood of six enzymes of the haem biosynthetic pathway have been determined in 12 patients with rheumatoid disease, six of whom were anaemic. The porphyrin and porphyrin-precursor intermediary products of haem biosynthesis were also determined in blood, urine and faeces. No significant differences were found between anaemic and non-anaemic subjects. Failure of delta-amino-laevulinate synthase activity to increase in response to anaemia may be the nature of the marrow unresponsiveness suggested as one factor in the causation of the anaemia. Normal ferrochelatase activity and normal concentrations of free protoporphyrin support the view that iron is effectively unavailable although present in normal amounts. Coproporphyrinogen oxidase activity was significantly depressed. | |
| 6427355 | Immunoglobulin (Gm) markers and alpha 1-antitrypsin (PI) types in rheumatoid arthritis and | 1984 Apr | No Gm allotype, haplotype or phenotype was increased or decreased in frequency in two autoimmune diseases, rheumatoid arthritis (RA) or chronic active hepatitis (CAH) in comparison with control frequencies. The frequencies of the Gm haplotypes among 206 controls were 0.70, 0.19 and 0.11 for fb, ag and axg , respectively. Neither Gm heterozygosity nor homozygosity was associated with either disease. There was no interaction between alpha 1-antitrypsin (PI) and Gm type in the two diseases. | |
| 85283 | [The lupus erythematosus (LE) phenomenon. Status in 1978]. | 1978 Dec 29 | The results of 835 studies of LE cells carried out over 8 years in 563 clinical cases of various nature are reported. The LE phenomenon--i.e. LE cells, LE globs and rosettes--was encountered exclusively in patients with LES, whereas tart-cells, nucleophagocytosis A and nucleophagocytosis B, although present in initial LES, and particularly in regressing LES, were very frequent in many other conditions. It is therefore held that true LE phenomenon is pathognomonic of LES since so-called AR with LE cells can be considered a clinical variant of LES, whereas lupoid hepatitis remains a vague, uncertain syndrome. | |
| 302538 | [Two-phase course of IgM and rheumatoid factors during D-penicillamine therapy]. | 1977 May | 16 patients with definite and classical rheumatoid arthritis (A.R.A. criteria) were under regular control for 210 days. 11 of them were treated with D-penicillamine and 5 with gold. They were compared to a group of 34 healthy people. In addition to clinical observations the following investigations were carried out at intervals of 20 to 30 days: Latex-fixation test and Waaler-Rose, IgM, IgA, IgG, C3, C4, C3-proactivation, ESR, coeruloplasmin, iron, complete blood picture, gamma-GT, SGOT, SGPT, alk. phosphatase, creatinine, urea and full urinalysis. Furthermore antinuclear factors (ANF) and C-3 activating ANF were determined by indirect immunofluorescence. The following observations were made: 1. The serum level of immuno-globulins changed in a two-phase fashion during D-penicillamine treatment. Initially IgM decreased significantly until the 60th to 80th day. During the 80th to 210th day it tended to increase. Rheumatoid factors changed in a similar way. 2. There was a significant correlation between the IgM serum level and the average titer of the Latex-fixation and Waaler-Rose tests. 3. The other parameters did not change significantly. 4. In one case the ANF became positive and showed a tendency to increase in titre. With higher titres complement activation was demonstrated. The treatment was discontinued. Thereafter the ANF titres and complement binding decreased gradually. | |
| 6525784 | A comparison of therapies which may influence trace metals in rheumatoid arthritis. | 1984 Dec | Forty-five patients with active rheumatoid arthritis (RA) were treated with D-Penicillamine (DPA), zinc sulphate or trien for 24 weeks. Clinical and biochemical assessments were made on eight occasions during the treatment period. Results supported the view that DPA is efficacious causing both clinical and biochemical improvement, whereas zinc sulphate provided clinical benefit in some patients without improving the biochemistry, and trien was ineffective in both respects. The results indicate the need for more thorough investigations of the effect of drugs on trace metal distribution in RA. | |
| 6969974 | Circulating protein complexes in D-penicillamine therapy of rheumatoid arthritis. Correlat | 1980 | Eighteen of 24 patients with rheumatoid arthritis showed intermediate IgG-containing complexes on preparative ultracentrifugation before treatment with D-penicillamine. Serial analyses of these showed strikingly close correlation in reduction of IgG as well as alpha 1-antitrypsin-IgA complexes. Three patients did not respond to treatment clinically, and retained both types of complexes. Complexes virtually disappeared in all responders. Only small changes were found in total IgG or IgM levels and the reduction of IgA levels was moderate, except for one case who developed IgA deficiency. The importance of further analysis of non-responders is stressed. | |
| 6630253 | Two-stage reimplantation for the salvage of infected total knee arthroplasty. | 1983 Oct | The results of eleven two-stage reimplantations to salvage eleven infected total knee arthroplasties in ten women (seven with osteoarthritis and three with rheumatoid arthritis) were evaluated after an average follow-up of thirty-four months. The staged procedures included removal of all of the components of the prosthesis and all cement, then six weeks of parenteral antibiotic therapy (monitored by maintaining serum bactericidal levels at a peak dilution of 1:8), and finally reimplantation with a total condylar-type prosthesis. All antibiotics were discontinued after reimplantation. At follow-up, no patient had had a recurrence of the original infection, but one had a hematogenous infection with a different organism secondary to an infected bunion. The results after reimplantation were rated excellent in five knees, good in four, and fair in two. Weakness of the extensor mechanism with an extension lag was the most frequent complication. We do not believe that antibiotic therapy alone is adequate for the management of an infection around a prosthesis. The method described appears to be effective but it is costly and time-consuming. The surgical procedures and medical management are technically difficult, often special equipment and a custom-made prosthesis are required, and there are no shortcuts. | |
| 6585186 | Carpal tunnel syndrome and subsequent rheumatoid arthritis in the 'fibrositis' syndrome. | 1984 Apr | Eight of 11 patients who satisfy Smythe's criteria for the 'fibrositis' syndrome have subsequently developed carpal tunnel syndrome. Six of the 8 patients have gone on to develop an inflammatory polyarthritis, 3 of whom are seropositive and satisfy the criteria for classical rheumatoid arthritis. The relationship between the 'fibrositis' syndrome and rheumatoid arthritis is not clear, but the additional complication of carpal tunnel syndrome in 'fibrositis' points to certain patients with 'fibrositis' developing an inflammatory polyarthritis of rheumatoid type. Acceptance on a definition of 'fibrositis' would enable further prospective studies to take place, but at present the term is used to describe many other nonarticular conditions that do not satisfy Smythe's criteria. | |
| 6232028 | Distribution of activated B lymphocytes in the circulation and synovial fluid in rheumatoi | 1984 May | The circulating peripheral blood of 13/28 patients with definite or classical rheumatoid arthritis (RA) had increased numbers of spontaneous in vivo active immunoglobulin-producing B lymphocytes detected by a reverse hemolytic PFC assay (mean = 3000 (1310-7920) Ig PFC/10(6) B cells) compared to an age/sex-matched control population (mean = 550 (300-900) Ig PFC/10(6) B cells). Among the remaining 16 RA patients who had normal numbers (less than 900 Ig PFC/10(6)) of such circulating B cells, 5 patients had increased numbers of activated B cells in the synovial fluid and 6 patients had no increase. Extraarticular features (nodules and vasculitis) in 11/13 patients and advanced but relatively inactive synovitis characterized those RA patients with increased numbers of active circulating B cells. In contrast, extraarticular features were seldom observed (1/16) among the remaining patients with normal numbers of active circulating B cells. Among these patients, more active generalized synovitis characterized those patients with increased numbers of active synovial fluid B cells compared to those patients with normal numbers. These studies imply that in RA patients, whose disease is primarily articular, active Ig synthesis is limited to the synovial compartment, while in those with extraarticular features active Ig-producing B cells also appear in the circulation. | |
| 526442 | Neutrophil marrow profiles in patients with rheumatoid arthritis and neutropenia. | 1979 Dec | Neutrophil marrow cellularity was determined in 14 neutropenic patients with rheumatoid arthritis (RA) from measurements of neutrophil-normoblast ratios in marrow biopsies and ferrokinetic estimates of marrow normoblasts. A marrow profile was developed for each patient comprising the numbers of promyelocytes and myelocytes, of metamyelocytes and bands, and of segmented neutrophils in whole marrow. In each case a maturation ratio was calculated by dividing the number of metamyelocytes and bands by the number of promyelocytes and myelocytes. The physiologic marrow response to loss of neutrophils from circulation was assumed to be an increase in promyelocytes and myelocytes due to proliferation and influx, a reduction in segmented cells due to early release, and a normal maturation ratio. The results were interpreted in the light of the 95% confidence limits for data previously obtained from 13 normal subjects: in patients with neutropenia reduced or basal numbers of promyelocytes and myelocytes were interpreted as absence of the anticipated proliferative response; increased numbers of marrow segmented cells were attributed to failure of release; a low maturation ratio was assessed to reflect intramedullary cell loss. The pattern in two patients with Felty's syndrome was consistent with a physiological response to neutrophil destruction. The other 12 patients had neutrophil marrow abnormalities. Seven patients with Felty's syndrome and four patients without splenomegaly had absolute or relative hypoplasia of neutrophil marrow or low maturation ratios. One patient with a normal spleen size had an increased number of marrow segmented cells yet failed to mobilize cells normally in response to dialysis coil-activation of C3. Abnormalities of neutrophil marrow may contribute to neutropenia in RA irrespective of the presence of splenomegaly. Recognition of neutrophil marrow abnormalities in these patients may be of value in prognosis and management. | |
| 162670 | Long-term tolerability study of Voltaren. | 1975 | Clinical and laboratory examinations were conducted in order to assess the long-term tolerability of Voltaren, a new anti-inflammatory and analgesic agent. Pre-treatment, repeated on-treatment and after-treatment investigations of haemoglobin, erythrocyte count, total and differential leucocyte count, platelet count, SGOT, SGPT, alkaline phosphatase, total serum proteins and urinary protein and sugar were conducted in 13 patients. The period of treatment with Voltaren was 110 to 559 days. In all these tests, there were no unwanted effects attributable to long-term treatment with Voltaren. Our study would indicate that Voltaren is a safe drug which has no effect on the organs of haemopoiesis, nor on hepatic or renal function, even in long-term therapy. Therefore, Voltaren can be used as an anti-inflammatory and analgesic agent not only in short-term therapy but also in the long-term treatment of chronic diseases. | |
| 496454 | Constrictive pericarditis, pyopericardium, and tamponade with rheumatoid arthritis. | 1979 Aug | Constrictive pericarditis and pyopericardium with tamponade in a patient and rheumatoid arthritis is described. No fever was recorded despite a litre of pus in the pericardial sac, perhaps because of previous treatment with hydrocortisone. Echocardiography is a diagnostic advance. |
