| 322268 | Immune deposits in the dermo-epidermal junction in rheumatoid arthritis. | 1977 | Skin biopsies from forty patients with rheumatoid arthritis were studied for presence of immune deposits in the dermo-epidermal junction zone. In about half of these unselected patients with classical and definite rheumatoid arthritis, IgM, complement components and fibrinogen antigenic material were found. A positive correlation is demonstrated between immune deposits and the presence of cryoglobulins in serum. The presence of complement components in the skin deposits was found to be clearly related to the clinical activity of the disease, as judged by Lansbury's index. | |
| 6334466 | [Significance of antinuclear anti-histone antibodies]. | 1984 | The results of routine antihistone antibody (AHA) assay in a preliminary series of 189 sera are presented. There were 23 positive tests (systemic lupus erythematosus, 8 cases; drug induced SLE, 4 cases; rheumatoid arthritis 7 cases; and multiple sclerosis, 1 case; chronic active hepatitis, 1 case; systemic sclerosis, 1 case and primary biliary cirrhosis 1 case). The results of routine assay in 5 other patients groups are reported: 30 spontaneous SLE (9 positive AHA), 63 rheumatoid arthritis (2 positive AHA), 19 Sjögren syndrome (no AHA), 11 primary biliary cirrhosis (1 positive AHA) and 7 mixed connective tissue disease (no AHA). | |
| 691197 | Toxicity of penicillamine. A serious limitation to therapy in rheumatoid arthritis. | 1978 Oct 20 | A retrospective study of penicillamine toxicity in 156 patients yielded a high incidence of toxic reaction (62%), necessitating discontinuation of the drug therapy in 36% of the patients. Of the total group, proteinuria occurred in 14%, hematologic toxic reaction in 11%, mucocutaneous toxic reaction in 28%, and gastrointestinal intolerance in 12%. | |
| 10877 | [Kates forefoot arthroplasty (author's transl)]. | 1976 Oct 25 | In a series of 93 forefoot arthroplasties (71 of them followed up), the majority of the cases showed good results of Kates' procedure. The most frequent sources of errors are inadequate treatment of the plantar skin and the formation of steps in the line of resection of the mid-tarsal bones. Rheumatic and degenerative forefoot deformities are equally well suited for this procedure. Forefoot deformities combined with pes equinus appear to be less suitable. | |
| 4078961 | Cricoarytenoiditis in rheumatoid arthritis: comparison of fibrolaryngoscopic and high reso | 1985 Dec | Cricoarytenoid involvement in rheumatoid arthritis has been assessed in 32 patients by combining clinical evaluation, direct fiberoptic laryngoscopy (DFL), and high resolution computerized tomography (CT). Symptoms were inconstant, variable, and rarely prominent. Absence of symptoms does not exclude an involvement. One case presented as an acute respiratory distress. The study showed an unexpected frequency of involvement with 75% of abnormal DFL and 72% of abnormal CT. Semiology of laryngoscopy and CT are described. | |
| 7279257 | [Gastrointestinal changes in mixed connective tissue disease. Apropos of a clinical case]. | 1981 Sep 22 | A case of mixed connective tissue disease is described. It began as chronic juvenile arthritis and progressed to acquire the typical features of SLE, PSS and PM. Dyspepsia and the patient's poor general condition, by focussing attention on the digestion and absorption functions, revealed the presence of the gastrointestinal alterations that often accompany SSP. | |
| 70840 | Immunoglobulin deposits in the dermo-epidermal junction zone in patients with systemic lup | 1977 | In biopsies from normal-looking skin, immune complexes in the dermo-epidermal junction zone were found by a direct immunofluorescence technique in 14 of 17 patients with systemic lupus erythematosus, in 6 of 12 patients with rheumatoid arthritis, but in none of 10 patients with temporal arteritis and 25 normal controls. Blood samples were obtained simultaneously from all patients and high titres of IgG organ-nonspecific antinuclear factors with complement-fixing properties were found to be closely related to systemic lupus erythematosus. IgG granulocyte-specific antinuclear factors were related with rheumatoid arthritis, while high concentrations of plasma fibrinogen were characteristic of temporal arteritis. No significant increases or differences in blood values of alpha2-macroglobulin were found between the groups and no correlation was found with deposits in the skin. | |
| 6589808 | Anti-type II collagen antibodies in rheumatoid arthritis. The influence of HLA phenotype. | 1984 May | Antibodies to native chick and bovine Type II collagen were measured by radio immunoassay, in 83 rheumatoid arthritis (RA) patients and 14 normal controls. Anti-chick Type II collagen and anti-bovine Type II collagen antibodies were found in 48% and 43% of RA patients, respectively. A strong correlation of antibodies to chick and antibodies to bovine collagen was described, suggesting cross-reactivity between different collagen species. There was an association between the presence of anti-native Type II collagen antibody and the expression of HLA-DR2. It is suggested that the production of anti-collagen antibody may be under genetic control in RA, but not associated with the major genetic marker of disease susceptibility, HLA-DR4. | |
| 6660242 | Azathioprine and cyclophosphamide as slow-acting drugs for rheumatoid arthritis. | 1983 Dec 30 | Therapy with azathioprine and cyclophosphamide is described as reducing disease activity in rheumatoid arthritis. The well recognized untoward effects are tractable save for the definite augmentation of carcinogenesis, a measurable risk that is regarded as acceptable in treating rheumatoid arthritis with azathioprine and rheumatoid arteritis with cyclophosphamide. | |
| 304735 | An account of pleural effusions, pulmonary nodules and cavities attributable to rheumatoid | 1978 Jan | Nine case histories and references to published reports are used to illustrate the manifestations and management of pleural effusions, lung nodules and lung cavities which may occur in cases of rheumatoid disease. Repeated aspiration of effusions seldom is useful. They often are chronic and symptomless. What is taking place in some turbid and purulent effusions is debatable, since there can be an associated leucocytosis without infection. In the presence of acute symptoms, such as rigors, careful evaluation of such effusions is required, since there have been fatal examples with rather uncertain bacteriological findings. Lung nodules ordinarily cause a radiographic blemish without symptoms but may predispose to small haemoptyses or may rupture into the pleural cavity to cause a pneumothorax, usually requiring surgical resection of the nodule, whether or not a pleural effusion is present. Some nodules and lung cavities do not have the histology of the typical necrobiotic nodule but it is unlikely that they are fundamentally different. Large cavitated lung lesions which closed on azothioprine treatment are described, together with similar untreated cavities which became secondarily infected with a fatal outcome. It is suggested that the history of possible rheumatoid disease, even of 'aches and pains' must be sought if this aetiology for pleural effusions, lung nodules and unusual lung cavities is not to be overlooked, with the penalty of diagnostic thoracotomy or wrong treatment for the patient. | |
| 3894257 | A controlled trial of tiaprofenic acid against indomethacin in patients with rheumatoid ar | 1985 | A multicentre double-blind crossover study of tiaprofenic acid 600 mg daily against indomethacin 75 mg daily was carried out in 68 patients with rheumatoid arthritis to compare short-term efficacy and tolerance. There were no significant differences in efficacy between the two treatments, but significantly fewer C.N.S. side-effects were associated with tiaprofenic acid treatment. Five patients withdrew during the course of the study due to side-effects and all were receiving indomethacin. | |
| 6318348 | [Clinical study of Bi-Profenid in rheumatologic practice]. | 1983 Dec 12 | The effectiveness and tolerance of Bi-Profenid as 150 mg tablets were analyzed in a multicenter study. Each of the 288 patients entered in the study had one of the main conditions found in rheumatologic practice: arthrosis of the hip or knee, rheumatoid arthritis or ankylosing spondylarthritis. Each patient was given one 150 mg Bi-Profenid tablet twice daily for 30 days. Overall effectiveness, as assessed by the pain scale test, produced improvement in 87.3% of cases. In degenerative rheumatic diseases, nocturnal pain, pain upon mobilization and walking distance were very significantly improved. In inflammatory rheumatic diseases, the significantly improved parameters were nocturnal pain, morning stiffness and functional indexes of rheumatoid arthritis. Tolerance was outstanding or very good in 77.1% of cases and the dropout rate was only 7.6%. | |
| 7389203 | Humoral and cellular immune mechanisms of neutropenia in patients with Felty's syndrome. | 1980 Feb | The objective of these studies was to assess the relative role of humoral or cellular immune mechanisms in the neutropenia of Feltry's syndrome. The amounts of neutrophil-bound IgG were measured by a sensitive antiglobulin inhibition assay. These values were increased in eight out of seventeen patients with Felty's syndrome over the highest values seen with seventeen patients with rheumatoid arthritis without leukopenia or twenty-six normal individuals. The levels of serum IgG neutrophil-binding activity from thirteen out of twenty-one patients with Felty's syndrome were greater than the highest values seen with normal sera compared to six out of thirty sera from patients with rheumatoid arthritis alone. A strong correlation was observed between the levels of direct neutrophil-bound IgG and the serum IgG neutrophil-binding activity for the seventeen patients with Felty's syndrome. Inhibition of normal marrow granulocyte colony growth greater than 40% was seen with the peripheral blood mononuclear leucocytes from five out of eleven patients with Feltry's syndrome. All five patients had normal levels of neutrophil bound IgG and normal to moderately increased levels of serum IgG neutrophil binding activity. In contrast, of the six patients whose mononuclear leucocytes did not inhibit granulocyte colony growth, three had markedly elevated levels of neutrophil-bound IgG and four had elevated levels of serum IgG neutrophil binding activity. These results suggest that humoral and cellular immune mechanisms of neutropenia may be present in different subsets of patients with Felty's syndrome. | |
| 6966152 | Lymphocyte transformation to denatured type I collagen and B lymphocyte alloantigens in rh | 1980 Apr | Peripheral blood lymphocytes transformed significantly to denatured type I collagen in 22 of 38 patients with rheumatoid arthritis (58%), 1 of 9 patients with Reiter's disease (P less than 0.05), and 9 of 32 controls (28%) (P less than 0.01). Determination of HLA antigens revealed significant differences between 24 rheumatoid arthritis (RA) patients and a control population for HLA-DRw4 (75% versus 23%). No correlation was observed between lymphocyte transformation to collagen and antibodies to collagen, rheumatoid factor, stage or duration of RA, or HLA antigens. | |
| 6373053 | A new assay for rheumatoid factor. | 1984 Jun | This solid-phase immunoassay for detection of rheumatoid factor involves a specially prepared indium surface that renders protein layers visible and therefore does not require tagged protein. Using appropriate discriminatory values, we found agreement with results of a standard latex-fixation test in controls and patients with rheumatoid arthritis. About half of the patients with rheumatoid arthritis that were seronegative by this latex fixation test had positive tests by the present assay. Rheumatoid factor of both the IgM and IgA class may be easily assessed. | |
| 7161788 | JPC-80, a new slow acting antirheumatoid drug. | 1982 Nov | JPC-80 has been administered to man for the first time. Twelve patients received doses up to 300 mg daily for up to 12 weeks. Three suffered significant, but not serious, side effects: 1 skin rash, 1 elevation of liver enzymes, 1 diarrhea. All signs or symptoms returned to normal on discontinuation of drug. Four of 8 patients receiving cumulative doses of over 20 g showed moderate or major improvement. In patients with clinical improvements the mean erythrocyte sedimentation rate fell from 51 to 21, and rheumatoid factor titers fell from 1444 to 647. This pilot study justifies additional controlled studies. | |
| 205952 | Collagenase immunolocalization in cultures of rheumatoid synovial cells. | 1978 May 19 | Cultures of rheumatoid synovial cells that have been enzymatically dissociated and are adherent to a culture vessel are morphologically heterogeneous. When these cells are cultured on a collagenous substrate for 2 to 6 days at 37 degrees C in serum-free medium, they produce collagenase. A monospecific antibody to human collagenase has localized the enzyme extracellularly around cytoplasmic extensions of dendritic cells and intracellularly within a few macrophage-like and fibroblast-like cells. | |
| 188134 | Collagenase production by rheumatoid synovial cells: stimulation by a human lymphocyte fac | 1977 Jan 14 | Human peripheral blood lymphocytes incubated in culture for 1 to 3 days at 37 degree C, but not at 4 degree C, release a soluble factor which can stimulate, up to 400-fold, collagenase production by isolated, adherent, rheumatoid synovial cells. Production of lymphocyte factor is enhanced by phytohemagglutinin or concanavalin A. By gel filtration the factor has an apparent molecular weight of about 12,000. | |
| 54168 | Electron microscopic demonstration of immunoglobulin deposition in rheumatoid cartilage. | 1975 Nov | Horseradish peroxidase (HRPO) conjugated with goat antihuman IgG, goat antihuman IgM, and aggregated human IgG has been used as a enzymatic marker to stain IgG, IgM, and rheumatoid factor in rheumatoid cartilage. When Hrpo-anti IgG and HRPO-anti IgM were used, immunoglobulin deposits were not observed in nonrheumatoid cartilage. However 7 of 8 rheumatoid cartilage specimens stained with HRPO-anti IgG showed electron-dense deposits. Three rheumatoid specimens stained with HRPO-anti IgM showed similar findings. Both of 2 rheumatoid specimens also stained positively with HRPO conjugated with aggregated IgG, a finding indicating that rheumatoid factor was present. The deposits were seen between the collagen fibers of the superficial layer of the cartilage to a maximal depth of 22 mu from the surface (average: 7 mu). The amorphous fibrinous material on the surface of the cartilage was also stained. The demonstration of IgG, IgM, and rheumatoid factor in the superficial zone of rheumatoid cartilage suggests that immune complexes are deposited in the cartilage in this disease. | |
| 6332690 | Generation of interleukin-2-dependent T cell lines from synovial fluids in rheumatoid arth | 1984 Oct | Synovial fluids from rheumatoid arthritis (RA) patients were found to contain activated T lymphocytes that could be maintained as continuous T cell lines (CTCL) in the presence of the T cell growth factor, interleukin (IL)-2. The CTCL predominantly expressed the OKT8 phenotype and were Ia antigen positive. IL-2-dependent RA CTCL could be maintained in an active dividing state by the presence of RA synovial fluids, whereas IL-2-dependent CTCL from mitogen stimulated PBL failed to respond to the fluids, which were shown to contain IL-2. This suggested that RA CTCL exhibit unique properties not possessed by normal PBL CTCL. The CTCL generated from activated synovial T lymphocyte populations in RA may be used to assess the functions of these cells and their responses to regulatory factors. |
