984905 | Serum immunoreactive gastrin in rheumatoid arthritis. Further observations on its identity | 1976 Jun | Serum immunoreactive gastrin is raised in some patients with rheumatoid arthritis (RA). In this paper paired samples taken within 30 minutes of each other show that this phenomenon is reproducible. Dilution curves show identity between gastrin from RA patients and from patients with no RA, and the raised immunoreactive gastrin concentration is demonstrable in patients who do not have chronic atrophic gastritis and in whom both basal and stimulated acid output concentrations are normal. Samples of gastric mucous membrane obtained from the body of the stomach and gastroscopy under direct vision in 18 patients with raised serum immunoreactive gastrin concentrations were normal. | |
800382 | A double-blind crossover comparison of Orudis (ketoprofen) and indomethacin in the treatme | 1976 | Twenty-three patients with rheumatoid arthritis participated in a double-blind crossover investigation of ketoprofen (Orudis) and indomethacin. Ratings which assessed the degree of joint involvement showed consistently greater improvement with Orudis, and side-effects occurred with less frequency. The majority of patients expressed a definite preference for Orudis. | |
313795 | Platelet aggregation and aggregation inhibition by different antiglobulins and antiglobuli | 1979 Aug | Antiglobulin complexes were isolated from rheumatoid arthritis (RA) sera in order to investigate their ability to aggregate human platelets and to influence platelet aggregation induced by heat-aggregated IgG. Eleven of 38 seropositive RA sera showed a significant platelet aggregation (PA) titer as compared to 40 normal control sera. No correlation was observed between sheep T cell agglutination titers and PA titers of individual sera. Ten of 22 RA antiglobulin preparations containing IgG, IgM, and IgA antiglobulins and antiglobulin complexes also showed positive PA tests. Such preparations were able to inhibit PA brought about by heat-aggregated human IgG. When IgG and IgM antiglobulins were tested separately, only IgM antiglobulins showed this inhibitory effect, whereas IgG antiglobulins were inactive. Neither IgG nor IgM antiglobulins induced PA alone. Reassociated IgG antiglobulin complexes consisting of carefully prepared IgG and isolated IgG antiglobulins were able to induce PA. Platelet aggregation by RA sera was thus shown to be due to IgG antiglobulin complexes present in the sera. It can be concluded from these experiments that the composition of antiglobulin complexes in individual sera comprised of antiglobulins of different classes and IgG "antigen" is responsible for PA results in vitro. In pathophysiologic terms, the reaction of IgG antiglobulin complexes with thrombocytes in vivo may be an important step in the chain of events leading to generalized vascular damage and deposition of immune complexes in vessel walls which is thought to be responsible for the development of generalized vasculitis in RA. | |
3907887 | Atopy and rheumatoid arthritis. | 1985 Nov | The prevalence of rheumatoid arthritis (RA) was studied among 266 atopic patients attending an allergy clinic. Two patients had definite RA, a prevalence similar to that seen in the general population. We also studied the prevalence of atopy (positive skin-prick tests) and diseases associated with atopy among forty patients with RA and forty age- and sex-matched controls. The two groups had a similar prevalence of atopy (5 RA patients, nine controls) and atopic diseases (fourteen RA patients, fourteen controls) and they did not differ with respect to blood eosinophil counts or total serum IgE. Positive RAST tests to inhaled allergens were found in three RA patients and five controls and all patients had negative RAST tests to milk and egg. It was concluded that patients with rheumatoid arthritis have a normal prevalence of atopy and atopic diseases and we found no evidence that allergic factors contributed to the arthritis of the forty RA patients in the study. | |
6508860 | Fractures after rheumatoid arthritis. A population-based study. | 1984 Dec | In a population-based study, the incidence of osteoporotic fractures in patients who have been diagnosed as having rheumatoid arthritis was investigated. This incidence was found to be increased, though not dramatically so: the relative risk for hip fracture, for example, was 1.5. Univariate analyses generally indicated increased risk associated with increasing age, earlier age at diagnosis of rheumatoid arthritis, disability, impaired ambulation, steroid use, and thinness, and decreased risk associated with obesity and estrogen use. In multivariate analyses, only aging, impaired ambulation, and thinness were identified as independent risk factors. | |
6623007 | Nerve palsy after knee arthroplasty in patients with rheumatoid arthritis. | 1983 | Forty-two consecutive knee arthroplasties on rheumatoid knees (19 Attenborough, 20 Total Condylar, 3 Marmor) were examined pre- and postoperatively for signs of below-the-knee nerve lesions. Sixteen of these knees were also studied neurophysiologically (EMG). Four patients (knees) had peroneal nerve palsy, three early and one late. Three further knees had only EMG signs of nerve lesion. Predisposing factor was correction of flexion contracture of more than 10 degrees and especially when combined with varus change in alignment. Preoperative EMG could not predict nerve lesion. | |
357231 | A double-blind crossover evaluation of ketoprofen (Orudis) and placebo in rheumatoid arthr | 1978 | A two-week double-blind crossover study of ketoprofen, a non-steroidal antiinflammatory agent, and placebo was done in ten patients with active rheumatoid arthritis in order to obtain a preliminary efficacy estimate of this new drug. Even after only one week of treatment, joint activity was significantly reduced while other parameters of disease activity showed strong clinical trends in favour of the drug. Only one adverse reaction (mild nausea) was reported during ketoprofen therapy. At the conclusion of the double-blind study, seven patients volunteered to continue on ketoprofen to evaluate the tolerance of the drug during proptracted administration. All patients completed over twelve months of treatment. Overall, ketoprofen gave good control of pain and inflammation, gastro-intestinal disturbance was reported in a single instance and laboratory values were not adversely affected by the drug. | |
136263 | Kinetics of salicylate metabolism. | 1975 Jun | 1 Nine patients with rheumatoid arthritis or non-inflammatory backache were given soluble aspirin (65 mg/kg body weight) daily. There was no significant difference between the plasma salicylate of those with rheumatoid arthritis and those with backache. 2 Two patients had plasma salicylate values that differed significantly from the remainder but neither these results nor the marginal differences between plasma salicylate levels of the others could be explained by individual variations in the capacity for excreting salicyluric acid or salicyl phenolic glucuronide. 3 Increasing the dose of aspirin in four patients demonstrated the reduced proportions of salicyluric acid and salicyl phenolic glucuronide excreted at high doses and the increased importance of unchanged salicylic acid as an excretory pathway. These findings are consistent with a limiting capacity for salicyluric acid and salicyl phenolic glucuronide synthesis and excretion. 4 The findings in one patient suggested that inter-subject variations in the capacity for producing salicyl phenolic glucuronide and salicyluric acid may have an effect on plasma salicylate levels at high doses of aspirin. | |
7340448 | Effect of inflammatory arthritis on dexamethasone receptors in phagocytes--a possible role | 1981 Dec | Synovial tissue cells from patients with seropositive rheumatoid arthritis bind dexamethasone in a similar fashion to the classical steroid receptors on other cells. In contrast, synovial fluid cells and blood PMNLs from these patients bind dexamethasone with much reduced affinity. Some component of plasma may interfere with the binding of dexamethasone to its receptor. | |
7280482 | Expectations and outcome of total hip replacement. | 1981 May | The preoperative function, expectations of pain relief and expectations of improvement in activities of daily living were compared with the results nine months after total hip replacement in 145 patients with osteoarthrosis or rheumatoid arthritis. patients improved functionally and their expectations generally were met. They were most satisfied with improvements in pain relief and mobility but 28% still expressed disappointment because specific expectations were not fulfilled. The expectations of doctors were higher than those of occupational therapists. | |
3980505 | Cervical myelopathy and posterior atlanto-axial subluxation in patients with rheumatoid ar | 1985 Apr | Posterior atlanto-axial subluxation, which is uncommon and usually is considered a benign condition, was associated with cervical myelopathy in four patients with rheumatoid arthritis. The cause of the myelopathy appeared to be posterior kinking of the spinal cord without demonstrable compression. Contrast-enhanced sagittal imaging or computerized tomographic sagittal reconstruction provided the best means of demonstrating the abnormal configuration of the spinal cord. Halo traction and occipitocervical fusion yielded satisfactory results in all four patients after follow-up of one to two years. We developed a method to provide rigid fixation of an occipitocervical fusion in which a corticocancellous iliac-bone graft was backed with metal mesh, wired in place, and reinforced with methacrylate. | |
6432414 | Comparison of auranofin and aurothioglucose in the treatment of rheumatoid arthritis: a si | 1984 Mar | Fifty-two patients with rheumatoid arthritis were studied in a single blind trial comparing aurothioglucose and auranofin. The duration of the study was 52 weeks. Twenty-six patients, 13 in each treatment group, dropped out during the first year of treatment. The main reason for discontinuing treatment with aurothioglucose was adverse reactions and, in the auranofin group, lack of efficacy. In those patients who continued therapy the results of treatment were comparable; patients on aurothioglucose improved slightly more than auranofin treated patients, although the difference was not statistically significant. | |
1221923 | Wrist cysts and fistulae. An arthrographic study of the rheumatoid wrist. | 1975 Oct | An arthrographic study of the wrist joint, in which 65 rheumatoid wrist joints were satisfactorily shown, gave a high incidence of significant abnormalities even in the absence of clinical signs of wrist involvement. Several synovial protrusion cysts were shown and corresponded to localized clinical swellings on the volar aspect of the wrist joint. These cystic swellings may be apparent before the onset of polyarthritis and may be differentiated from ganglia arthrographically by their association with other features suggesting erosive synovitis. Cystic swelling over the lower end of the ulna is shown to be frequently due to synovial hypertrophy of the inferior radioulnar joint in either a dorsal or volar direction. In one case a fistulous tract was delineated connecting the midcarpal joint with the volar surface of the wrist by a flexor tendon sheath. | |
7021072 | A single-dose analgesic study of naproxen sodium and soluble aspirin in patients with rheu | 1981 | Nineteen patients with moderate or severe pain due to rheumatoid arthritis were entered into a double-blind, crossover comparison of single doses of 550 mg naproxen sodium and 900 mg soluble aspirin. Pain relief, measured on a visual analogue scale, showed a rapid onset of action of both drugs. Pain relief reached 50% of its maximum within 1 hour on both drugs. There were no significant differences in the pain relief/time curves. Five patients found no relief of pain with either drug but of the remaining 14 patients 10 reported an onset of action of both drugs within half an hour. Nine patient on naproxen sodium and 7 on soluble aspirin rated pain relief as good or very good. At the end of the study, 7 patients preferred soluble aspirin, 4 preferred naproxen sodium and the remainder gave no preference. There were no side-effects on eigher drug. | |
6713800 | Rheumatoid arthritis of the crico-arytenoid and crico-thyroid joints: a radiological and c | 1984 May | Low-voltage neck radiography and indirect laryngoscopy was performed in 22 randomly selected rheumatoid patients with the purpose of detecting intralaryngeal arthritis. Radiographic evidence of erosive arthritis of the crico-arytenoid (CA) joints was found in 45% of the patients. Clinical acute CA arthritis without erosive changes was present in two patients, the overall incidence of CA arthritis being 55%. The incidence was higher in females (65%) than in males (20%). The CA arthritis was asymptomatic in 58% of the patients. Radiography revealed osseous destruction at the crico-thyroid joint in four females. | |
6884397 | Role of penicillamine for the induction of myasthenia gravis. | 1983 | Penicillamine and derivatives of this drug were tested for lymphocyte-activating properties. D- as well as L-penicillamine induced in vitro DNA synthesis in mouse splenocytes, whereas D-penicillamine methyl ester, N-acetyl-D-penicillamine and D-penicillamine disulfide were devoid of stimulatory properties. Lymphocytes from athymic mice were also responsive. However, we were unable to detect an increased antibody secretion in mouse spleen cell cultures exposed to penicillamine. Human peripheral blood lymphocytes from healthy individuals as well as from patients with penicillamine-induced myasthenia gravis only gave minor proliferative responses after in vitro penicillamine exposure. Furthermore, there were no differences in proliferative capacity between these two groups. Cultivated human peripheral blood or spleen cells were not activated to antibody secretion in the presence of penicillamine. There were no signs of myasthenia gravis using single-fiber electromyography recordings in patients with rheumatoid arthritis being on penicillamine treatment or in mice from several different mouse strains receiving penicillamine in their drinking water. However, NZB/NZW hybrid mice receiving penicillamine had increased amounts of antinuclear and anti-dsDNA antibodies. | |
1123721 | A sensitive method for the comparative bioassay of nonsteroidal anti-inflammatory compound | 1975 Jan | A method for the comparative bioassay of nonsteroidal anti-inflammatory agents is presented which exploits the early inflammation induced by injection of adjuvant into the plantar surface of a hind paw of the rat. The inflammation reaches a peak on the 4th postinjection day. Daily treatment with nonsteroidal anti-inflammatory agents reduces paw volumes and the associated impairment of body growth with optimal improvement on the 4th postinjection day. In this model, phenylbutazone has shown significant activity at doses as low at 1.33 mg/kg/day. Statistically valid comparative assays conducted at dose levels equivalent to or below those used in human therapy yield potency ratios with relatively narrow confidence limits. Potencies relative to phenylbutazone for inhibiting primary adjuvant-induced inflammation are: aminopyrine, 0.066 (0.36-0.11)95%; aspirin, 0.087 (0.039-0.19)95%; mefenamic acid, 0.98 (0.64-1.6)95%; flufenamic acid, 13 (7.4-26)95%; meclofenamic acid, 23(16-33)95%; and indomethacin, 53 (35-82) 95%. Ancillary and sometimes quantitative information is also provided by the improvement in well being of the animals as reflected in body weight changes with treatment. | |
6657873 | Pathological mourning: a key factor in the psychopathogenesis of autoimmune disorders. A s | 1983 | Prolonged mourning has been recorded as a precipitant life event in RA and other autoimmune disorders, but other events such as retirement, redundancy and injury have also been identified. The author's submission is that pathological mourning is present in all patients with AI disease, and that other events such as those mentioned are only precipitant because they uncover mourning until then kept in check by occupation and use of work as a drug. When time for reflection and loneliness allows long suppressed ambivalent feelings, guilt and bitterness to surface, remorse over 'unfinished business' increasingly dominates the patient's thoughts. Children and young people rarely have the opportunity to mourn, thus early loss is often paramount and is awakened from the unconscious years later when further losses of key figures or surrogates, including pets, occur or are anticipated. Psychotherapy involves helping patients resolve their pathological mourning. | |
6339966 | Extracapillary glomerulonephritis with necrotizing vasculitis in D-penicillamine-treated r | 1983 | Rapidly progressive glomerulonephritis occurred in a woman with rheumatoid arthritis (RA) who had been treated with D-penicillamine for 3 months. Light microscopy study of the kidney showed severe glomerulonephritis with crescent formation in 50% of glomeruli and necrotizing vasculitis. Immunoflurescence revealed IgA and C3 granular deposits diffusely distributed along the capillary walls. The patient was treated with steroid 'pulse', antiplatelet agents and heparin and a partial recovery of renal function was observed after 2 months of anuria. This renal picture is unlike that reported in RA and a causative role for D-penicillamine is suggested. | |
6275861 | Titers of antibodies to RANA in rheumatoid arthritis and normal sera. Relationship to Epst | 1981 Dec | The disease specificity of antibodies to rheumatoid arthritis nuclear antigen (RANA) was examined by comparing anti-RANA titers in sera from 100 patients with rheumatoid arthritis (RA) with sera from 93 healthy controls. Anti-RANA antibodies were found in 86% of the RA sera and 56% of the controls. The higher titers in the RA sera were unrelated to clinical features or to measurements of circulating immune complexes or rheumatoid factors. To study the relationship of these antibodies to previous Epstein-Barr virus (EBV) infection, antibodies to the EB virus capsid antigen (VCA) were examined and found in 94% of the RA sera and 97% of the adult controls. Four of the six RA sera without anti-VCA antibodies had detectable anti-RANA antibodies, so that we might suggest anti-RANA can arise in the absence of EBV infection. From absorption experiments with non-EBV transformed extracts, we inferred that high anti-RANA titers could be due to reactions with non-Epstein-Bar virus related nuclear antigens. These data cast doubt on current speculation about a possible pathogenic role for Epstein-Barr virus in this disease. |
