6979628 | T lymphocyte subpopulations in rheumatoid arthritis. | 1982 Jan | The number of various lymphocyte subpopulations in the peripheral blood of 28 patients with definite rheumatoid arthritis (RA) were studied. The results were correlated with the disease activity, as assessed by the Ritchie index, erythrocyte sedimentation rate and clinical impression. Patients with active RA showed decreased numbers of T mu lymphocytes, strongly increased numbers of Tnull lymphocytes and slightly increased percentages of Fc gamma lymphocytes as compared to 22 healthy donors. Patients with inactive RA had similar, less striking, but significant changes in T mu and Tnull lymphocytes, but in contrast to patients with active RA had Increased numbers of T gamma lymphocytes. The imbalances in T mu and Tnull cells in patients with RA might be explained by endogenous T mu cell activation, resulting in increased numbers of Tnull cells. | |
464783 | Arthritic hand response to pressure gradient gloves. | 1979 Aug | Five women with osteoarthritis and 10 with rheumatoid arthritis and finger joint involvement wore a pressure gradient glove, a control glove, or no glove in a randomly assigned sequence. All were outpatients. Each patient wore the assigned glove nightly for 1 week, after which a battery of subjective and objective data, including number of tender joints, ring size, grip strength, palmar temperature, and hand function were obtained. In all, 105 separate examinaion sessions were completed over 7 visits, with each hand serving as its own control in the experimental design. The palmar skin temperature was elevated in both patient groups when either a pressure gradient or control glove was worn. In patients with rheumatoid arthritis, the only significant difference was that the pressure gradient glove reduced ring size when compared to the control glove or no glove. No differences were detected in the patients with osteoarthritis. | |
6507107 | Azathioprine as single drug in the treatment of rheumatoid arthritis induces complete supp | 1984 Aug | Natural killer (NK) activity against K 562 target cells was studied in 60 patients with definite or classic rheumatoid arthritis (RA), grouped by medication into 1) Controls not in remission-inducing therapy, 2) Patients treated with penicillamine, and 3) Patients treated with azathioprine. NK activity was found to be completely suppressed in the azathioprine group as compared with the controls (3.2 +/- 4.2% versus 35.9 +/- 14.8% specific lysis; p less than 0.01) except for one patient who received incomplete azathioprine treatment. The NK activity was not suppressed in the penicillamine group. | |
7018409 | Double-blind trial of dapsone against placebo in the treatment of rheumatoid arthritis. | 1981 Jun | Dapsone given over 14 weeks in a dose of 50 mg a day for 1 week and thereafter 100 mg a day was found to have a beneficial effect in rheumatoid arthritis when compared with placebo administration to a matched group of patients. Significant improvement in 5 out of 7 clinical measurements and in erythrocyte sedimentation rate, viscosity, C-reactive protein was found in those patients taking dapsone. There was significant improvement compared to the placebo group in 2 out of the 7 clinical measurements and again in all 3 acute-phase reactants. The drug was quite well tolerated over the 14-week duration of the trial. The tendency to cause haemolysis will be its main limiting factor as a practical alternative to other suppressive agents currently in use. | |
409749 | A quantitative evaluation of rheumatoid arthritic activity with Tc-99m HEDP. | 1977 Oct | In an attempt to develop a quantitative method of evaluating rheumatoid arthritic activity, Tc-99m HEDP joint uptake values and joint-to-bone ratios were studied in ten adult rheumatoid arthritic patients and 17 nonarthritic patients. A joint-to-bone activity ratio of 1.8 at the fourth hour after injection (RA Index) discriminated clinically active rheumatoid arthritic joints from control joints with 95% accuracy. Serial studies on five patients during drug trial demonstrated a positive correlation between RA Index and the clinical manifestations of rheumatoid arthritic activity. The RA Index may be a useful quantitative parameter for evaluation of rheumatoid arthritic activity following therapy. | |
6772463 | Synovial membrane in rheumatoid arthritis: determination of glycosaminoglycans and age-dep | 1980 | From 16 synovial membranes patients with rheumatoid arthritis morphological parameters as well as the GAG distribution pattern have been determined using 2 methods each. The results were checked by discriminant and regression analysis: The total GAG concentration of the synovialis was significantly correlated with the sum of the parameters "fibrin in organization", "granulocytes" "nad "necroses" (acute activity). A highly significant correlation between the age of patients and the severity of chronic morphological alterations (basic activity, especially proliferation) was found. The percentage of CS plus DS was positively correlated with the age of patients as well as with the basic activity of the disease, especially with the proliferation. - Contrary to this, HA was significantly decreased when related to the "chronic" parameters. No correlation could be demonstrated between the GAG components and criteria of the acute activity. The evaluating system of STIEHL and GEILER is to be preferred for obtaining morphologic-biochemical correlations. Furthermore, a diagram is proposed demonstrating the cumulative progression of rheumatoid arthritis in the synovialis as related to the GAG pattern. Its combination with morphological data (scars, proliferation, exudation) may help to describe the development of the disease more acurately. | |
7125714 | Serum copper and erythrocyte superoxide dismutase in rheumatoid arthritis. | 1982 Oct | Serum copper and thiol levels an caeruloplasmin activity were determined and compared with measurements of articular index, erythrocyte sedimentation rate, and zinc and haemoglobin levels in patients with rheumatoid arthritis. Superoxide dismutase activity, thiol, zinc, and copper levels of haemolysate were measured and compared with each other and to the above parameters. In serum, caeruloplasmin activity increased and thiol levels decreased, whereas in the haemolysate superoxide dismutase activity decreased and thiol levels increased. It is suggested that the changes in copper levels and in the activities of process which may be copper-dependent between plasma and cytosol in patients with rheumatoid arthritis reflect a change in oxidative status of the blood which may have implications in the pathogenesis of the disease. | |
6520829 | Lymphocyte subsets and inflammatory indices in synovial fluid and blood of patients with r | 1984 Dec | Lymphocyte subsets defined by monoclonal antibodies, C reactive protein (CRP), immune complexes (IC), rheumatoid factor (RF), C3, C4 and neutrophil and lymphocyte numbers were measured in synovial fluid (SF) and blood samples from 11 patients with rheumatoid arthritis. SF showed an increased percentage of T cells, Ia+ cells and OKT8+ cells and a reduced percentage of B cells and OKT4+ cells, when compared with blood. Reduced levels of CRP, RF, C3 and C4 were found in SF compared with blood. Comparisons between cellular subsets and other indices in SF revealed a positive correlation between neutrophil numbers and IC, CRP, and RF with a negative correlation between neutrophil numbers and numbers of T cells and OKT8+ cells. A similar negative correlation was found in blood between OKT8+ cells and both CRP and RF. These results indicate an association between increasing disease activity and a lack of suppressor/cytotoxic cells in both circulating and intraarticular compartments. An additional important finding was the lack of correlation of Ia+ cells in both SF and blood with neutrophil numbers, CRP, IC, C3 and C4 or RF. | |
2906452 | Plasma and synovial fluid concentrations of sulphasalazine and two of its metabolites in r | 1985 | A study was made of plasma and synovial fluid levels of sulphasalazine, one of its dissociation products--sulphapyridine and a metabolite of the latter--acetyl sulphapyridine in patients with rheumatoid arthritis (RA) who were in a steady state on sulphasalazine therapy. Combined sulphapyridine levels were significantly higher than those of sulphasalazine both in plasma and synovial fluid. Synovial fluid levels of both drugs correlated with their plasma levels and were generally slightly lower. Some patients accumulated sulphasalazine and sulphapyridine in the synovial fluid and the mean concentration of sulphasalazine was higher in the fluid than in the plasma. The explanation for this is uncertain. The concentration of combined sulphapyridine in synovial fluid was related to local joint inflammation and more active systemic disease. No consistent association was found between sulphasalazine levels and local or systemic activity. The higher sulphapyridine levels in synovial fluid found in this study suggest the possibility that this moiety could play a more active role in RA than it does in inflammatory bowel disease. | |
4746132 | Painful feet in rheumatoid arthritis. | 1973 Oct 20 | Pain in the feet is an important diagnostic feature and a major management problem of rheumatoid arthritis. Of 50 hospitalized patients, 28% recalled painful feet as the sole presenting symptom of their disease.RHEUMATOID DISEASE COMMONLY AFFECTS THE FEET: 90% of the patients studied complained of foot pain at some time during the course of their disease, 86% had clinical involvement and 92% had radiological changes in their feet.The forefoot is most frequently involved. Midfoot involvement was noted in 68% but was symptomatic in only 22%. Changes in the ankle were least common but always symptomatic. | |
7038361 | Laser therapy of rheumatoid arthritis. | 1980 | Thirty people with classical or definite rheumatoid arthritis received laser exposure to a Q-switch neodymium laser that operated at 1.06 micrometer with an output of 15 joules/cm2 for 30 nsec. One hand was lased at the proximal interphalangeal (PIP) and metacarpal phalangeal (MCP) joints, whereas the other hand was sham lased. The patient, physician, and occupational therapy evaluators did not know which hand was being lased. Twenty-one patients noted improvement of both their MCP and PIP joints of both hands during laser therapy. Twenty-seven noted improvement of their PIP joints and 26 noted improvement of the MCP joints during therapy. Heat, erythema, pain, swelling, and tenderness all improved with time in both hands, but the lased hand had more significant improvement in erythema and pain. There was also significant improvement in grasp and tip pressure on the lased side. The level of circulating immune complexes as measured by platelet aggregation decreased during lasing. The improvement may be related to laser exposure. The exact role that laser radiation has upon rheumatoid arthritis and its mechanism of action remain to be elucidated. | |
1190849 | The foot in chronic rheumatoid arthritis. | 1975 Aug | The feet of 200 consecutive admissions with classical or definite rheumatoid arthritis were studied. 104 were found to have pain or deformity. Clinical involvement of the joints was seen more often than radiological joint damage in the ankle, but the reverse was the case in the midtarsal joints. The metatarsophalangeal joints were involved most frequently both clinically and radiologically. Sixty per cent of the patients required modified shoes but only a third of these had received them. The need for more shoes is clear, and although this is a highly selected group of patients they were all under specialist care. The increased expenditure on special footwear would benefit the patient, firstly by improving ambulation, and secondly perhaps by reducing the number of operations necessary. Hallux valgus was very common and occurred with similar frequency to disease in the other metatarsophalangeal joints. Although not exclusive to rheumatoid arthritis, hallux valgus must have been caused for the most part by the rheumatoid arthritis and if so, then it is suggested that the provision of suitable shoes for patients may be less costly than subsequent surgical treatment. | |
394279 | A double-blind comparison of diclofenac sodium (Voltarol) and placebo in inpatients with r | 1979 | This preliminary study compared placebo with diclofenac (50 mg, rising to 150 mg per day) in a crossover study for seven days in thirteen inpatients. Regardless of the marked overall effect of hospitalization, an additional effect of diclofenac on grip strength and p.i.p. joint swelling was demonstrated, as well as a significant reduction in pain and in analgesic requirements. In addition, an improved technique for assessing the effect of NSAI drugs on p.i.p. joint swelling is described. | |
897733 | Polycentric total knee arthroplasty. | 1977 Sep | Polycentric total knee arthroplasty in 56 patients provided significant relief of pain in 90.7% and a stable knee in 92.7%. Postoperative increase in range of motion averaged 13.7 degrees for all patients (18.5 degrees in rheumatoid arthritis and 8.7 degrees in degenerative arthritis). This increase in excursion is attributed to the design of the prosthesis, a vigorous postoperative rehabilitation program, and careful surgical technic. A failure rate of 12.7% was due to infection, mechanical instability and unexplained pain. Contraindications to surgery and technical recommendations are noted. | |

3872100 | Circulating immune complexes and rheumatoid arthritis: a comparison of different assay met | 1985 Feb | The performance of four different assays for circulating immune complexes-the C1q solid phase method, one using protein A and one using anti-IgG, C1q PEG, and the 2% PEG method-were compared in 61 patients with early rheumatoid arthritis followed up for two years. There were weak but statistically significant correlations between the results from some of the pairs of assays, but the changes over time from any single assay did not correlate with those from any of the other assays. None of the assays predicted either future disease activity, as measured by subsequent ESR, CRP, and articular index; or functional outcome, as measured by wrist extension, Steinbocker functional capacity, and the Stanford health assessment questionnaire. It is unlikely therefore that the measurement of immune complexes is of value in predicting early outcome in patients with rheumatoid arthritis. | |
1110997 | Multicentric reticulohistiocytosis: a rare cause of destructive polyarthritis. | 1975 Feb | A case is described of multicentric reticulohistiocytosis or lipid dermatoarthritis with early radiographic findings of subchondral erosions of the distal interphalangeal joint space, more marked that the erosions of the proximal interphalangeal joint space. The clinical and pathologic findings are reviewed. | |
1101352 | [Systematic study of sequential salivary gland scintigraphy during rheumatoid arthritis an | 1975 Mar | Sequential salivary scintigraphy has been practised systematically in 130 patients hospitalized in a rheumatology unit. These patients were suffering from typical, classical rheumatoid arthritis, rheumatoid arthritis with high positivity for anti-nuclear antibodies, clearly defined polyarthritis, systemic scleroderma, other types of collagenosis, forms of inflammatory polyarticular rheumatism other than rheumatoid arthritis and collagenosis, and from different degenerative diseases. The scintigraphic anomalies were divided in three stages according to a personal classification. Nine patients presented a patend Gougerot-Sjögren syndrome. All of them had abnormal or very abnormal scintigraphy. However, the patients with classical rheumatoid arthritis without signs of the Gougerot-Sjögren syndrome, also showed a high frequency of isotopic anomalies that were equally severe. These were clearly connected only with the particular diagnosis (with classical rheumatoid arthritis, but not with clearly defined polyarthritis or collagenosis). No other direct relationship could be established between these diseases and the clinical, radiological, laboratory, or therapeutic aspects of the case. On the other hand, they were often associated with a reduction in lacrymal and salivary secretion. These isotopic studies, in combination with other findings shed a new light on the Gougerot-Sjögren syndrome, taking into account the diffusion of the exocrine lesions and of the contributions of the most modern methods of investigation. | |
6306848 | Digitalgia paresthetica with digital neuropathy in rheumatoid arthritis. | 1983 Jul | Two cases demonstrate the digital neuropathy of rheumatoid arthritis with hyperpathia. This phenomenon occurs in types II and IV, but the paresthetic character has not been emphasized previously. | |
6205815 | A study of IgM rheumatoid factors in a middle-aged population of Northern Norway. | 1984 Jun | A random selection of 8807 blood samples was analysed for the presence of IgM rheumatoid factor (RF). The sera were obtained from an epidemiological survey of rheumatoid arthritis in a middle-aged population of Northern-Norway. The prevalence of IgM-RF was 1.36% for the total population, but a prevalence of IgM RF in healthy individuals between 0.48-0.49% was found with no significant difference between males and females. The majority of RF positive sera were low titred. Only 11.4% of the persons possessing serum IgM RF suffered from classical or definite rheumatoid arthritis. Eighty-one per cent of the IgM RF positive individuals converted to seronegativity in the course of 3.5 years. |
