| 1082388 | Enhanced uptake by guinea-pig macrophages of radio-iodinated human aggregated immunoglobul | 1975 Feb | A competitive radiobioassay method for soluble immune complexes in sera has been used to study sera from patients with rheumatoid arthritis. Twenty-eight out of sixty-two sera from selected seropositive rheumatoid patients were found to produce enhanced uptake of radio-iodinated human aggregated IgG by guinea-pig macrophages in contrast with the inhibition of uptake seen with SLE sera. Twenty-two out of the twenty-eight enhancing sera belonged to patients with cutaneous vasculitis. None of the twenty-two sera from seronegative rheumatoid patients possessed enhancing properties and none of these patients had clinical evidence of vasculitis. Three patients with seropositive SLE had sera with enhancing properties and had cutaneous vasculitis. We have shown that the enhancement is probably due to the presence in sera of immune complexes or altered IgG bound to rheumatoid factor. The possible mechanism has been investigated and it appears that there is increased binding of radio-iodinated aggregated IgG to free valencies on rheumatoid factor already bound to immune complexes. | |
| 169267 | Arthritic disorders of the adult radiocarpal joint: anatomic considerations and an evaluat | 1975 Jun | The anatomy and pathology of the radiocarpal compartment of the adult wrist are described in a study of human cadavers and 50 consecutive patients with radiocarpal joint abnormalities. The most frequently encountered diseases were adult onset rheumatoid arthritis (42) and calcium pyrophosphate deposition disease (22%). Features allowing radiographic diagnosis included the degree of symmetry and the presence of demineralization, sclerosis, joint space narrowing, subchondral cysts and erosions. Evaluation of abnormalities in other compartments of the wrist and the ulnar styloid is mandatory. | |
| 7191310 | [Controlled double blind comparison of acemetacin to indomethacin in patients with chronic | 1980 | In a double blind study [1-(p-chlorobenzoyl)-5-methoxy-2-methylindol-3-acetoxy] acetic acid (acemetacin, TV 1322, Rantudil¿) was compared with indometacin in 2 x 20 patients suffering from rheumatoid arthritis. The duration of the study was 3 weeks. The patients received 3 x 30 mg/d acemetacin or 3 x 50 mg indometacin in capsules. The therapy was controlled at accurately defined intervals. Statistical evaluation of the data regarding the influence on pain and motility did not reveal any significant differences between the two drugs. Neither the evaluation of the recorded side effects nor the laboratory tests showed any statistical difference between the two therapies. The gastrointestinal complaints occurred more frequently in the indometacin group (5 of 20, of these 3 withdrawals) than in the acemetacin group (3 of 20, of these 1 withdrawal). However, this difference was not statistically secured. Evaluation of the therapeutic effect did not reveal any significant differences between acemetacin and indometacin at the administered molar dose ratio of 1:2. However, the acemetacin therapy had a markedly improved gastrointestinal tolerability. | |
| 7439262 | Characterization of salicylate binding to synovial fluid and plasma protein in patients wi | 1980 Nov | Protein binding of salicylate in synovial fluid and plasma from patients with rheumatoid arthritis was studied by equilibrium dialysis. Protein binding in the synovial fluid was considerably lower at all salicylate concentrations studied (0.07 - 2.2 mM). Scatchard plots of the data were analyzed assuming binding to two classes of binding sites, each plasma sample being diluted to an albumin concentration equal to that in synovial fluid from the same patient. Binding to the primary binding sites was considerably decreased in synovial fluid in comparison with plasma. The affinity of the secondary binding sites was slightly lower. Thus, at a low therapeutic drug concentration, the decreased binding of salicylate to synovial fluid protein in patients with rheumatoid arthritis could mainly be accounted for by decreasing affinity of binding to the primary binding sites. | |
| 377472 | The use of penicillamine in the treatment of rheumatoid arthritis and scleroderma. | 1979 | The use of penicillamine in the treatment of rheumatoid arthritis and scheroderma is reviewed. Much of the worlds literature was collected including both open studies and control studies. Both types with over 1,300 patients in the open trials and as one would expect, a smaller group in the control trials, showed about 64 percent of the patients having good results. Side effects range from one quarter to one third of the treated patients. This seems to show penicillamine as an effective drug for the treatment of rheumatoid arthritis though with a multiplicity of side effects. Its use in the treatment of scleroderma is still uncertain. Because of the rarity of the disease the number of patients treated has been small and the data is conflicting. | |
| 334473 | Steroid-sparing action of flurbiprofen: use of an additional parameter of joint scans with | 1977 | A double-blind placebo controlled trial was carried out in 14 steroid-dependent patients with rheumatoid arthritis to assess the effectiveness and steroid-sparing action of flurbiprofen over a 4-week period. During the first week, the patients' steroid dosage was stabilized at the minimum necessary to control symptoms. They were then treated with either 100 mg flurbiprofen or placebo 3-times daily for 3 weeks. Steroid dosage was initially reduced to 50% of the stabilized dose and reduced further if practicable, depending on therapeutic response. Clinical assessments were made, at weekly intervals, of pain, swelling, tenderness, erythema, range of movement, grip strength, walking time, and duration of morning stiffness. Joint scanning of 99mTc uptake was also measured before and after treatment in 11 patients. The results showed that whereas 3 out of 6 patients on placebo has distinct inflammatory flare-up, this did not occur in any of the 8 patients on flurbiprofen. Moreover, 3 of the flurbiprofen group showed improvement and a further reduction in steriod dosage was possible in 3 patients. Improvements in joint scans correlated well with the clinical findings in 6 of 11 patients. | |
| 6407306 | Association of IgE antibodies to sodium aurothiomalate and adverse reactions to chrysother | 1983 Jun | The relationship between adverse reactions to chrysotherapy and specific IgE antibodies to sodium aurothiomalate (auIgE) was studied in 67 patients with rheumatoid arthritis (62) or psoriatic arthritis (5). Thirty patients (45 percent) had such antibodies versus none of the 27 control patients. Of the 34 patients in whom reactions to chrysotherapy developed, 23 (68 percent) had auIgE versus 7 (21 percent) without reactions (p less than 0.001). Mucocutaneous lesions were significantly associated with auIgE (p less than 0.001). All five patients with thrombocytopenia, but only one of five with the nephrotic syndrome, had auIgE. The patients with IgE response had higher total serum IgE levels (p less than 0.005), were more likely to be atopic (four to one), and had more recently received chrysotherapy (mean 2.8 +/- 1.95 years versus 7.0 +/- 5.75 years, p less than 0.001) than those without response, but did not differ by either the gold product or the total dose used. Chrysotherapy is associated with the production of specific IgE antibodies to a gold salt, and some mucocutaneous and hematologic reactions may be immunologically mediated. | |
| 6091700 | Cyclic nucleotides and calcium transport in cultured dermal fibroblasts from progressive s | 1984 Oct | Levels of cAMP were decreased and cGMP increased in progressive systemic sclerosis (PSS) fibroblasts compared with normal fibroblasts. PSS cells took up unusually large quantities of Ca++. The epinephrine-induced increases in cAMP were diminished sixfold and epinephrine-induced Ca++ uptake was abnormal in PSS cells. Considerable heterogeneity was observed in rheumatoid arthritis fibroblasts. Membrane-bound abnormalities in (PSS) cells may be of importance in the defective control of collagen production in progressive systemic sclerosis. | |
| 7433928 | Liver function in some common rheumatic disorders. | 1980 | Liver function was studied primarily by determination of serum gamma glutamyl transferase and alkaline phosphatase. In subsamples of patients the investigation was extended by determination of serum amino-transferases, isoenzyme analysis of alkaline phosphatase, 99mtechnetium scintigraphy, and liver biopsy. In 183 in-patients with rheumatoid arthritis, the serum gamma glutamyl transferase level was elevated in 47% and serum alkaline phosphatase (of liver origin) in 24%. A concomitant increase in serum aminotransferases was found in 15% of patients with elevated gamma glutamyl transferase level. A closely similar pattern was found in 45 patients with non-rheumatoid arthritis (ankylosing spondylitis, psoriatic arthritis, reactive arthritis, and undefined arthritis), and in 5 patients with polymyalgia rheumatica. In 23 patients with non-rheumatic inflammation (pneumonia), liver dysfunction was common, though the pattern of serum enzyme changes was different. In rheumatoid arthritis, liver scanning showed irregular or low uptake, but biopsy only indicated reactive hepatitis. Hepatotoxicity could not be traced to any single drug or combination of drugs given. On the contrary, chloroquine appeared to reduce serum gamma glutamyl transferase, and corticosteroids had a similar effect on serum alkaline phosphatase. In patients not treated with corticosteroids, both serum gamma glutamyl transferase and alkaline phosphatase were weakly to moderately correlated with laboratory indices of disease activity (ESR and serum orosomucoid). The frequently occurring isolated increase of serum gamma glutamyl transferase and/or serum alkaline phosphatase in arthritis may be an unspecific reaction to inflammation. | |
| 6162149 | [Beta-2-microglobulin and rheumatoid factor levels in the synovial fluid (author's transl) | 1980 Mar 29 | The object of this study was to determine whether levels of beta-2-microglobulin and of rheumatoid factor measured by an enzyme-immunoassay allowed good discrimination between inflammatory and degenerative arthropathies. A multiparametric study of synovial fluid was performed on 85 specimens from patients with rheumatoid arthritis, chondrocalcinosis, mechanical arthritis and traumatic arthopathies. A beta-2-microglobulin level of less than 4 mg/l is a result very mich in favor of a non-inflammatory arthropathy (48/49 cases). The quantification of intra-articular rheumatoid factor allows for reclassification in the context of sero-negative rheumatoid arthritis. | |
| 3875719 | Synovial fluid analysis--another look at the mucin clot test. | 1985 Apr | We analyzed the relationship between the mucin clot test and the synovial fluid (SF) leukocyte count in osteoarthritis, rheumatoid arthritis (RA), gout, and calcium pyrophosphate dihydrate crystal deposition disease. Except for RA there was no statistically significant relationship between white count and a tight mucin determination within the disease categories. For low (2 X 10(9) cells/l or less) leukocyte counts, the crystal induced arthropathies had a significantly greater proportion showing a tight reaction than found in the osteoarthritic and rheumatoid fluids. We propose that mucin clot determinations may reflect synovial membrane activity rather than SF leukocyte counts. | |
| 6182075 | Physical modalities for treating the foot affected by connective tissue diseases. | 1982 Jul | Physical therapy is often necessary in the optimum treatment of foot and ankle disorders associated with connective tissue diseases, particularly rheumatoid arthritis. Thermal modalities and transcutaneous electrical nerve stimulation use for pain control are described, as well as a therapeutic exercise, ambulatory assistive devices, below the knee bearing braces, and the prescription of appropriately supportive and corrective footwear and shoe modification are discussed in the context of increasing comfort and minimizing deformity and disability. | |
| 921346 | Xeroradiography in assessment of the rheumatoid hand. | 1977 Oct | Comparable conventional x-rays had xeroradiographs were obtained of the hands of 22 patients with rheumatoid arthritis. Each metacarpophalangeal and proximal interphalangeal joint was scored for juxta-articular osteoporosis, erosions, loss of joint space, soft tissue thickening, joint deformity, and osteophytes on a 0-3 scale. For 10 hands the films were reported again after 3 months, and each technique was reproducible. Comparison between the 2 radiographic techniques showed that overall they gave similar results, although osteoporosis was reported more frequently on conventional x-rays, and loss of joint space and synovial thickening on xeroradiographs. | |
| 6607820 | A multi-centre study of piroxicam in the treatment of osteoarthritis and rheumatoid arthri | 1983 | An open, multi-centre, non-comparative study was carried out in general practice to assess the efficacy and tolerance of piroxicam in 159 patients with osteoarthritis and 27 patients with rheumatoid arthritis. Initial dosage ranged from 10 to 40 mg piroxicam and all but a few patients continued treatment with 20 mg once daily. Mean duration of treatment was 47.5 days in the osteoarthritis group and 38.4 days in the rheumatoid arthritis group. Marked or moderate improvement was reported at the final visit by 68.6% and 87.7% of osteoarthritis and rheumatoid arthritis patients, respectively. The attending physician's assessment of efficacy indicated an excellent or moderate response in 89.3% of osteoarthritis patients and 84.7% of rheumatoid arthritis patients, with 71.2% of the former and 51.9% of the latter patients preferring piroxicam to the medication which was taken prior to the onset of the study. Highly significant numbers in each group reported an improvement in all parameters of disease activity. Side-effects, predominantly gastro-intestinal, were reported in 54 patients, but cessation of medication was required in only 14 patients. | |
| 6435987 | Oral gold in arthritis. | 1984 Oct | There are few drugs available with purported disease-modifying or healing effects in rheumatoid arthritis. The two agents that have gathered the most support in favor of these effects are parenteral gold and cyclophosphamide; however, both can produce intolerable toxicity. A new oral gold compound (auranofin; Ridaura) is being investigated in rheumatoid arthritis. Available studies suggest that auranofin may be slightly less effective than parenteral gold, but is significantly less toxic, the main side effect being diarrhea. There is evidence to suggest auranofin slows radiologic progression of the disease, but further studies are indicated. If further studies demonstrate a healing effect of the drug, comparable with data suggesting this effect for parenteral gold, auranofin may become a first-line agent in rheumatoid arthritis. | |
| 7409617 | Perichondrial grafting in rheumatoid metacarpophalangeal joints. | 1980 Jun | A pilot study of perichondrial grafting in rheumatoid metacarpophalangeal joints is presented. Eighteen separate joints have been grafted with a mean follow-up time of eighteen months. Results and indications for this method of joint reconstruction in rheumatoid patients are discussed. | |
| 6476733 | Wrist deformity in rheumatoid arthritis extensor carpi ulnaris tendon transfer. | 1984 Aug | A procedure designed to correct volar subluxation of the ulnar carpus in patients with rheumatoid wrist deformity is described. Twenty-five patients were treated with synovectomy, distal ulna resection, and transfer of the distal extensor carpi ulnaris to the extensor carpi radialis longus. Comfort and improved function were reported, and no significant complications were noted. Follow-up during the 14-month study period demonstrated improvement in volar-carpal subluxation confirmed on x-ray films, stability of metacarpal-phalangeal alignment, and no deterioration of the ability to ulnar deviate. | |
| 338391 | The effect of fenoprofen calcium (Nalfon) on levels of rheumatoid factor in patients with | 1977 | In 88.9% of a group of 18 patients with rheumatoid arthritis participating in an open-label study with fenoprofen calcium (Nalfon), there was observed a mean titre decrease in level of rheumatoid factor as compared to baseline levels. In follow-up, three months to one year later, a uniform titre increase above the mean level of the study period had occurred. In all cases the titre returned to baseline levels or higher. | |
| 7240427 | Nephelometry v differential agglutination titre in the measurement of rheumatoid factors. | 1981 Apr | IgM rheumatoid factors have been measured in 92 patients by both laser nephelometry and the traditional hospital procedure of a latex slide test followed by differential agglutination titre (DAT). Of the results 86% were in accordance by both methods, but seronegative patients with a high nephelometry score all showed, after reference to their clinical state and previous investigations, that the nephelometry result more accurately represented their clinical state than the DAT, which was shown to be in error in five out of the six cases. Six seropositive patients with low nephelometry scores were also studied; three were in complete remission on gold or penicillamine therapy. Nephelometry is both technically simpler and more reliable than the traditional DAT method, and our results suggest that it has some advantages over the DAT in routine use. | |
| 6611576 | The analgesic effects of transcutaneous electrical nerve stimulation and placebo in chroni | 1984 | The analgesic effects of high frequency transcutaneous electrical nerve stimulation (TNS), "acupuncture-like" TNS and placebo TNS were evaluated in 33 patients with rheumatoid arthritis and chronic hand pain using a randomized, double-blind, non-crossover design. An oscilloscope was employed to monitor the stimulator output in the TNS treatment groups and to provide strong suggestion and a focus of attention in the placebo treatment group. The two forms of TNS were applied at the highest intensity that could be tolerated by patients. Assessments of resting pain, joint tenderness, grip strength and grip pain were made before and after treatment. The pain and joint tenderness measurements showed high frequency TNS, "acupuncture-like" TNS and placebo TNS to be equally effective in producing analgesia of similar degree and trend over time. The grip strength measurements showed no significant change. The results obtained with placebo are probably due to the suggestion and attention effects of the visual stimulus. The implications of these results in respect to pain control pathways are discussed. Although TNS given at high intensity was shown to be no better than placebo applied with strong suggestion, this does not preclude its use as a method of pain control in rheumatoid arthritis. |
