| 4017316 | Gold nephropathy and renal amyloidosis in a patient with rheumatoid arthritis. | 1985 Apr | A 71-year-old Caucasian woman with rheumatoid arthritis, who had been treated with gold salts for 19 months, developed a significant proteinuria associated with nephrotic syndrome and renal impairment. Her renal biopsy revealed the unusual simultaneous occurrence of gold nephropathy and renal amyloidosis and she was treated by gold withdrawal, methylprednisolone pulses and azathioprine, with a good remission of symptoms. We describe the case and discuss the possible cause(s) of similar renal involvement and the results obtained with the combined therapy of steroids and cytotoxic drugs. | |
| 1166283 | Mycoplasma antibodies in rheumatoid arthritis. | 1975 | Sera of 100 patients under examination at the Outpatient Department of the Rheumatism Foundation Hospital were studied by the indirect hemagglutination technique, using both mycoplasma reference strains, and isolates from RA and SLE as antigens. The series consisted of five groups: I, definite RA (49 patients); II, probable RA (11); III, possible RA or nonspecific inflammatory arthritis (34); IV, osteoarthrosis (2); V, Reiter's disease (4). Mycoplasma antibodies in titres of 16 or higher were encountered in groups I-IV in 26, 8, 19, and one case respectively. Twenty-one out of 106 blood donors had antibodies against an isolate from RA and/or M. arthritidis strain PG 6. The titres found were 16 or 32, except in two cases, 128. In the definite RA group, 21 out of 26 patients possessing mycoplasma antibodies, showed titres of 16 or higher against isolates from RA and/or SLE, 12 against M. arthritidis strain PG 6 and/or Campo, 8 against M. fermentans, and 6 against a T-strain from NGU. Antibodies against M. arthritidis strain Campo were found more often than against strain PG 6. The longer the duration of the arthritic symptoms was, the more frequent seemed also to be the occurrence of mycoplasma antibodies. | |
| 609911 | Ulnar tunnel syndrome caused by anomalous muscles. Case report. | 1977 | Two cases of ulnar tunnel syndrome at the wrist are described. In both cases an anomalous hypothenar muscle, flexor digiti minimi brevis accessorius, was in part the causative factor. Contributing to the symptoms of nerve compression was swelling associated with rheumatoid disease and Colles' fracture, respectively. Decompression of the nerve including subtotal removal of the anomalous muscle effected complete recovery. Its phylogeny, morphology and clinical significance are discussed in relation to previously described anomalies of the hypothenar muscles. | |
| 4625157 | Studies on the first component of complement (C1) and the inhibitor of C1 esterase in rheu | 1972 Jun | The specific activity of C1 (haemolytic units per unit of C1q or C1s protein) was two to three times lower in synovial fluid of patients with sero-positive rheumatoid arthritis (RA) than in non RA or sero-negative RA fluids. These fluids contain a high ratio of C1s inhibitor to C1s. Experiments with radiolabelled C1s established that the C1s inhibitor in the synovial fluids of these patients is functional as it binds radiolabelled C1s. At the high ratios observed, it is possible that a complex of C1s and C1s inhibitor forms in these synovial fluids and alters the activation of the complement system. The potential for excess C1s inhibitor to slow or diminish complement utilization was shown by adding purified C1s inhibitor to serum in order to simulate the conditions in joint fluid (i.e. a high ratio of C1s inhibitor to C1s). Subsequent whole complement, C1 and C4 activites after incubation with selected immune complexes were higher as compared to controls without added inhibitor. | |
| 449407 | Synovial effusions containing cholesterol crystals report of 12 patients and review. | 1979 Jun | Cholesterol crystals were identified in 16 synovial fluids from 12 patients who were seen over the 14-year period 1964 through 1977. Ten of the 12 patients had rheumatoid arthritis of a median duration of 12 years. One patient had ankylosing spondylitis and another had iliopectineal bursitis without other joint disease. The fluids were usually turbid, white, or yellow in color and of thick consistency. When the synovial fluid concentration of cholesterol was determined, it was higher than the serum level. The swollen joints and bursae did not respond favorably to simple aspiration or corticosteroid injections but did to surgical synovectomy. No relationship was found between synovial fluid accumulation of cholesterol crystal and previous intra-articular corticosteroid therapy, serum lipoprotein abnormalities, intra-articular hemorrhage, or generalized arteriosclerosis. The results suggest that local factors are most important in the development of synovial fluid cholesterol crystals, but the exact mechanisms are unknown. The presence of cholesterol crystals in synovial fluid should suggest a severe persistent synovitis, knowledge of which may be helpful in diagnosis and planning therapy. | |
| 942272 | Circulating immunoblasts in polymyalgia rheumatica. | 1976 Apr | The percentage of immunoblasts circulating in the peripheral blood has been examined in a group of 29 patients with polymyalgia rheumatica (PMR). Less than 0.5% of immunoblasts were found in healthy young controls, but 18 of 29 unselected patients with PMR were positive when first tested, a similar proportion to that found in rheumatoid arthritis. Raised immunoblasts were found in only one of 12 elderly controls. The presence of circulating immunoblasts correlated with the activity of polymyalgia both as assessed by the erythrocyte sedimentation rate (ESR) and as assessed by an independent clinical observer. This was true in the group overall and in those patients where serial studies were made. Patients studied from the time of disease presentation showed a concurrent fall in ESR and in immunoblasts on starting steroid therapy. Detection of circulating immunoblasts can be a useful additional test in the assessment of disease activity in PMR, especially in cases with a low ESR. The presence of circulating immunoblasts supports the concept of an immunological aetiology for PMR. This is strengthened by the finding that raised immunoglobulins were more common in patients with circulating immunoblasts. | |
| 6167524 | Polyclonal B cell activator associated with alpha-2-macroglobulin in the serum of patients | 1981 | We investigated whether patients with rheumatoid arthritis have a polyclonal B cell activator (PBA) in their serum by using three methods: (1) the ability of any PBA to maintain the surface Ig of rabbit or human B cells in vitro; (2) the induction of blast transformation in human B lymphocyte cultures, and (3) stimulation of nude mouse spleen cells in vitro. All three methods indicated that a PBA is present in the serum of patients with rheumatoid arthritis but not in normal individuals or in patients with arthritis in which autoimmune phenomena have not been demonstrated. The entire PBA activity in rheumatoid arthritis patient serum was found associated with the macroglobulin fraction obtained by Sephadex G-200 chromatography and was precipitated by rabbit anti-human alpha 2-macroglobulin, but not by rabbit anti-Ig antibody. When alpha 2-macroglobulin was purified from patient serum the entire PBA activity was recovered in this fraction. Normal alpha 2-macroglobulin prepared by the same procedure had no PBA activity. Thus, the existence of a PBA associated with alpha 2-macroglobulin was demonstrated in serum of patients with rheumatoid arthritis. | |
| 87776 | Defective reticuloendothelial system function in rheumatoid arthritis. | 1979 Jun 23 | The function of the splenic reticuloendothelial system in patients with rheumatoid arthritis (R.A.) was assessed by determining the clearance of autologous heat-damaged erythrocytes from the circulation. 11/13 patients with active R.A. had a defect in the clearance of red cells and there was a significant inverse correlation between splenic function and the level of circulating immune complexes detected by a Clq-binding assay. Splenic function was normal in 13 patients with inactive disease who had been treated with either gold or prednisone. A serial study on 1 patient with active R.A. showed a clear correlation between fluctuations in disease activity, splenic function, and the level of circulating immune complexes. | |
| 734314 | Indomethacin or prednisolone at night in rheumatoid arthritis? | 1978 Feb | Indomethacin, 100 mg orally, was compared with prednisolone, 5 mg, as addititional therapy at night, in a two-week, double-blind, between-patient study in twenty-four in-patients with rheumatoid arthritis. Both therapies proved equally effective, and significantly lessened morning stiffness and increased grip strenght. Two patients with dyspepsia were discontinued from the indomethacin group. Using indomethacin at night avoided the central nervous system side-effects frequently seen with this compound. | |
| 4821008 | Aspirin and analgesic nephropathy. | 1974 Mar 30 | Renal function was studied in 17 patients with rheumatoid arthritis who had each consumed between 5 and 20 kg of aspirin. After an interval of two years 14 of these patients-seven of whom had consumed a further mean of 2 kg of aspirin-had their renal function retested. No relation was found between total dose, rate, or duration of ingestion and any aspect of renal function that was studied. All patients had plasma creatinine levels within the normal range, though slight depression in creatinine clearance was not uncommon.From this study and other published data we conclude that aspirin rarely if ever causes analgesic nephropathy when prescribed alone in doses appropriate to the treatment of rheumatoid arthritis. | |
| 408555 | [Indomethacin induced corneal deposits (author's transl)]. | 1977 May | After a summary of corneal changes, caused by drugs (gold, Chloroquine, Phenothiazines, Amiodaron), a personal case of indomethacin induced deposits is described. The chief characteristic was was a ring-shaped formation of the grey-whitish lines in the epithelium. A retinopathy was not present. | |
| 1082751 | Cutaneous vessel immune deposits in rheumatoid arthritis. | 1976 Jan | A study to determine the presence of immune deposits in the cutaneous vessels of normal-appearing skin was made in 39 patients with rheumatoid arthritis. Immune deposits in skin vessels were found in 20 of the 32 patients with seropositive rheumatoid arthritis. The frequency of such immune deposits was only slightly higher in patients with clinical vasculitis than in those without such vasculitis. There was an association among the presence of immune deposits in skin vessels, presence of antinuclear antibodies, and elevated serum levels of IgM and IgA. The major immunoreactants detected were IgM and C3. The presence of immune deposits in skin vessels does not differentiate seropositive rheumatoid aptients who have clinical vasculitis from those who do not have clinical vasculitis. | |
| 6214847 | Lymphocyte studies in rheumatoid arthritis. V. Suppressor cell function in peripheral bloo | 1982 | Peripheral blood lymphocytes from 30 patients with rheumatoid arthritis and 14 controls were examined for suppressor activity by two different assays. These were the Concanavalin-A-induced and the short-lived suppressor cell assays. There was no difference in suppressor activity between patients and controls, the suppressor activity of HLA-DR3 positive patients was no less than that of non-DR3 patients. However, patients with nodules showed reduced suppression in the short-lived suppressor cell assay when compared with patients without nodules. | |
| 991669 | [Total shoulder endoprosthesis design St. Georg]. | 1976 Oct | Experiences with shoulder replacement in 40 cases since 1966 and the development of a nonblocked total prosthesis are described. The replacement of both joint surfaces according to the principles of low friction arthroplasty ist needed to obtain relief of pain. The nonblocked system corresponds in a high degree to physiologic conditions. The shape of the implant and the meticulous reconstruction of the inner and outer rotator cuffs reduce the danger of dislocation considerably. Only small bone resection is necessary. In cases of dislocated compound fractures and of painful posttraumatic and rheumatic arthrosis, total replacement could be an alternative to resection of the humeral head as well as to shoulder arthrodesis. | |
| 1084008 | [New research on synovial enzymology]. | 1976 May | After reviewing previous work on the subjects, the authors show that the synovial fluid in subjects with inflammatory rheumatism contained higher levels of lysozyme and of beta-glucuronidase comparable with those of the acid phosphatases and of lacto-dehydrogenase that they were interested in previously. | |
| 1141284 | Metatarsal osteotomy for metatarsalgia. | 1975 May | An oblique osteotomy in the distal half of the metatarsal shaft is described for the treatment of metatarsalgia due to prolapse of one or more of the middle three metatarsal heads. Thirty-eight patients who have had this operation have been followed up for a period of from two to five years. The operation is simple, recovery is rapid and symptoms have been well relieved. | |
| 6373897 | The use of radionuclide bone and joint imaging in arthritic and related diseases. | 1984 Mar | Patients with arthritic complaints are seen frequently by podiatrists, who must establish a differential diagnosis. When combined with the patient's history, physical examination, joint aspiration, laboratory data, and radiographs, bone and joint scans provide a sensitive and objective means of arriving at an accurate diagnosis. | |

| 59385 | Multi-variate analysis of serum protein rheumatoid arthritis. | 1976 | The content of IgG, IgA, IgM, transferrin, haptoglobin, alpha2 macroglobulin, alpha1 acid glycoprotein, alpha1 antitrypsin, beta1C/1A globulin and beta1E globulin in the sera of 172 female rheumatoid patients and 132 female non-rheumatoid subjects was measured by the single radial immunodiffusion method. Rheumatoid patients were classified into 3 groups according to their stage and class. Canonical discriminant analysis revealed that the alpha1 acid glycoprotein and beta1C/1A globulin was of assistance in differentiating the rheumatoid and non-rheumatoid groups. There is no significant difference in serum protein levels between rheumatoid factor positive and negative groups, whereas IgA and beta1E globulin levels exhibited certain differences between these two groups. Among the results of other clinical tests, the correlation observed between ESR and serum protein levels in rheumatoid arthritis should be mentioned. | |
| 6721883 | Extracellular presence of the lysosomal proteinase cathepsin B in rheumatoid synovium and | 1984 May | The presence of the lysosomal proteinases cathepsin B and cathepsin D at extracellular sites in rheumatoid synovium was demonstrated using the antibody capture technique. Unlike cathepsin D, the cysteine proteinase cathepsin B was commonly detected only at the edges of the synovial explants. Radioimmunoassay and enzyme activity assay of these proteinases demonstrated that both were released from rheumatoid synovial cells in comparable amounts. Since lysosomal cathepsin B is unstable and denatured at physiologic pH and the antibody used only recognizes inactivated enzyme, we believe the selective detection of cathepsin B at the edge of the synovium may be due to the proteinase maintaining a native conformation within the explant, where the pH may be low enough to permit this. By use of a fluorescent substrate in a sensitive, continuous enzyme assay, cathepsin B was shown to express significant activity at neutral and alkaline pH before being inactivated. This and earlier work from this laboratory indicate that cathepsin B secreted by rheumatoid synovial cells may possess extracellular activity in vivo and be involved in the degradation of connective tissue macromolecules. |
