6940531 Oral ulceration and neutropenia associated with naproxen. 1980 Dec A case history of oral ulceration associated with the use of naproxen has been presented. A woman, 33 years of age, was first treated with indomethacin then naproxen for rheumatoid arthritis. The ulcers which occurred initially during indomethacin therapy worsened when naproxen was substituted and abated when it was suspended. This side effect of naproxen has not previously been reported. The possible mechanism which could have caused this side effect has been discussed.
6623017 Vitamin B12 binding proteins (transcobalamin and haptocorrin) in serum and synovial fluid 1983 The vitamin B12 (cobalamin) binding proteins, transcobalamin and haptocorrin, were measured in serum and synovial fluid of 12 patients with rheumatoid arthritis (RA) and 11 patients with traumatic synovitis (TS). Levels of both the cobalamin-binding proteins of synovial fluid were markedly elevated in RA compared with TS. In serum, the haptocorrin concentrations were significantly increased in RA vis-à-vis TS. In synovial fluid of RA patients, the transcobalamin and haptocorrin concentrations were positively correlated to the concentrations of macrophages and polymorphonuclear granulocytes, respectively. The demonstration of increased synovial fluid transcobalamin/total protein and haptocorrin/total protein ratios in RA vis-à-vis TS provides further evidence of a local production or liberation of the cobalamin-binding proteins in synovial fluid of patients with RA.
7282112 Myasthenia gravis as a complication of D-penicillamine therapy in rheumatoid arthritis. 1981 May During the period 1971-79, 301 patients in the Voivodeship Integrated Hospital in Szczecin were treated with D-penicillamine (D-PCN). The complications observed included two cases of myasthenia gravis (MG), both in rheumatoid arthritis (RA) patients, one a 41-year-old man given the drug for 8 months, the other a 50-year-old woman treated in the same way for 4 months. In both patients, pneumomediastinography revealed enlargement of the thymus. Thymectomy followed by histological examination in both cases showed the existence of germinal centres and Hassall's bodies in the typical glandular texture. Follow-up examination 3 years later confirmed complete healing in the male patient and a marked improvement in the female patient.
7009858 The simultaneous assessment of four nonsteroidal antiinflammatory drugs in rheumatoid arth 1980 Nov We compared naproxen and sulindac with salicylates, ibuprofen and placebo in the treatment of rheumatoid arthritis. The active medications were significantly more effective than placebo but not different from one another. Both naproxen and sulindac appeared to be more effective in the higher doses studied but a considerable variation in response emphasizes the need to individualize the dose requirements. A single-blind, non cross-over trial technique utilizing entirely subjective measurements in the form of self-assessment charts is presented. The method is simple and rapid and can be used for the simultaneous comparison of a number of antirheumatic drugs.
81282 The geographical distribution of multiple sclerosis, rheumatoid arthritis, rheumatic heart 1978 Sep 12 The comparative geography of multiple sclerosis (MS) and nonneurological diseases considered to be autoimmune is of great interest. But there are few appropriate investigations. Some have found an increase in the frequency of MS, rheumatoid arthritis and rheumatic heart disease depending on the geographic latitude. Nevertheless, the significance of the latitude effect as an indicator of a possible etiological relationship between MS and these conditions has been questioned. In this paper, the frequency of MS, rheumatoid arthritis, rheumatic heart disease and poststreptococcal nephritis is reported from Sardinia where appreciable differences in climatic and socioeconomic conditions exist. There was a positive correlation of the distribution of MS with the distribution of rheumatic heart disease and poststreptococcal nephritis. On the other hand, no correlation was found with the distribution of rheumatoid arthritis.
853224 A simple method for detection of IgG rheumatoid factor. 1977 A simple method for detection of IgG rheumatoid factor (RF) in sera and joint fluid is described. The technique is based on the action of 0.1 M 2-mercaptoethanol mixed directly with the material. After 2 h of incubation determinations of human anti-IgG were performed by latex agglutination test. Comparison with data obtained by using the conventional method, sequential 24 h treatment with 0.1 M 2-mercaptoethanol and 0.01 M iodoacetamide, shows similar results for both methods. A correlation was observed between the presence of IgGRF in synovial fluid and a severe clinical course with invalidating forms in patients suffering rheumatoid arthritis.
910089 Repeated corticosteroid injections into knee joints. 1977 Aug The effect of intra-articular injections of corticosteroids repeated over a period extending from four to 15 years on the radiological appearances of knee joints affected by rheumatoid arthritis and osteoarthritis has been studied. In 65 cases, the X-ray films of 15 showed no deterioration, 38 showed minimal or moderate deterioration, 10 showed marked deterioration and only 2 showed gross deterioration. The results do not support the contention that repeated intra-articular injections of corticosteroids will inevitably lead to rapid joint destruction. The authors are of the opinion that intraarticular injections of corticosteroids, if used judiciously, have an important part to play in the management of chronic arthritis.
6116280 Neurological complications of connective tissue and other "collagen-vascular" diseases. 1981 Aug A variety of neurological complications may occur in the various connective tissue and "collagen-vascular" diseases. Most of these complications are due to vasculitis affecting various sites in the central or peripheral nervous system. While the evidence for definitive vasculitis in SLE is not strong, small vessel damage usually is present in anatomic sites which correlate well with clinical features. Although patients with rheumatoid arthritis also may have vasculitis, neurological complications are usually related to nerve compression by rheumatoid nodules or the arthritic process itself. Considerable controversy exists regarding the accuracy of various diagnostic tests. While corticosteroids are the mainstay of therapy for these conditions, there are no definitive studies proving their efficacy.
3970591 Use of simple analgesics in rheumatoid arthritis. 1985 Jan The usefulness of anti-inflammatory drugs in rheumatoid arthritis (RA) is beyond dispute. The role of simple analgesics is less clear and has been disputed. A survey of 21 rheumatologists indicated that a majority sometimes supplemented anti-inflammatory treatment of RA with simple analgesics. A random sample of 120 RA patients treated by the same doctors revealed that 47% ranked pain relief as the most desirable objective of their treatment and 54% were taking analgesics regularly. Of those receiving analgesics as well as non-steroidal anti-inflammatory drugs 48% considered the former to be the more effective preparations. Almost half the patients on analgesics were taking drugs without the knowledge of the rheumatologists, who may have underestimated their patients' desire for pain relief.
6856162 [Proglumetacine in rheumatoid arthritis]. 1983 Jun 23 Proglumetacin, 450 mg/day, was administered during 1 month to 32 rheumatoid arthritis patients in anatomical and functional stage II or III. Overall, more than 50% of pts responded to the treatment, in particular those in stage II, in whom Ritchie's articular index, nightly and daily pain significantly decreased. Those pts in stage III who did not respond to proglumetacin even when administered at high dose, did not respond to indomethacin, either. Tolerance resulted very good, as only 3 complaints of mild and transient epigastric pain and 1 of skin rash were observed, but no one related to the C.N.S. High efficacy and good tolerance set therefore proglumetacin aside from indomethacin, A.S.A. and most of the recent non steroidal anti-inflammatory agents.
6970551 In-vitro T cell mediated function in patients with active rheumatoid arthritis. 1981 Feb In-vitro synthesis of peripheral blood lymphocytes from patients with rheumatoid arthritis was measured after stimulation with phytohaemagglutinin (PHA) in a short-term, serum-free culture system. Diminished responses were found in 16 out of 17 consecutive patients with active disease. Normal PHA responsiveness was recovered by assaying Ficoll-Hypaque isolated E rosette forming cells in serum-free medium, indicating basically normal T cell function in RA. Preincubation of normal peripheral blood lymphocytes (or isolated E rosette forming cells) with sera obtained from patients with active RA for 30 minutes at 4 degrees C or 37 degrees C blocked PHA responsiveness in 34 out of 43 tests. This suggests that serum blocking factors may be responsible for reduced T cell reactivity in RA.
64650 Cell electrophoretic analysis of lymphocytes and polymorphonuclear cells from patients wit 1977 Jan 15 Cell electrophoresis was performed on peripheral-blood lymphocytes obtained from 11 patients with rheumatoid arthritis (R.A.) and 16 normal controls. On the basis of cell frequency/mobility histograms each subject's lymphocyte electrophoretic profile was resolved into a bimodal distribution of fast and slow cells. The mean electrophoretic mobility (E.P.M.) of the fast-cell population was similar in controls and in R.A. patients but the mean E.P.M. of the slow population was significantly slower in R.A. than in the controls. In the R.A. patients the E.P.M. of the polymorphonuclear cell population was significantly slower than that of P.M.N. cells in the peripheral blood of controls.
1264654 [Rheumatoid polyarthritis: should corticotherapy be interrupted in case of gastro-duodenal 1976 Jan 17 The possibility of healing of a corticosteroid-induced ulcer depsite the continuation of the treatment, is now an established fact. It is thus reasonable to continue corticosteroids in those cases where interupption severely compromises the prognosis. The chances of healing of the ulcer would appear to be great, especially when corticosteroids are being used in low dosage, but the exact frequency of healing remains unknown, just as the frequency of ulcers due to corticosteroid therapy has not been accurately established.
574689 [A new acute-phase protein. II. Quantitative determination in the serum of patients with r 1979 Sep 15 An antigen (SF1 or TSGA) originally found in the inflammable synovial fluid of man, which comes from the cytoplasm of neutrophils, possesses the properties of an acute-phase-protein. The production of a specific antiserum against this antigen and the method of its quantitative determination by means of the Mancini-technique are described. In 89 sera of patients with rheumatoid arthritis the antigen was determined. First results of this investigation which speak for a dependence of the antigen concentration in the serum on activity and progression of the disease are reported.
908172 Increased EA-rosette formation by lymphocytes from patients with rheumatoid arthritis. 1977 Aug A modified method for estimating erythrocyte-antibody (EA) rosette formation of human peripheral blood lymphocytes (PBL) reveals consistent differences between rheumatoid arthritis (RA) patients tested and healthy control subjects. Using this method we find an average of 27 +/- 0-8% (standard error of mean) of PBL from 120 RA patients forming EA rosettes in contrast to only 6 +/- 0-6% of PBL from ninety-five healthy controls, and 7 +/- 0-9% from eighteen patients with systemic lupus erythematosus (SLE). This difference is not due to monocytes forming EA rosettes or to T-cell sheep red blood cell (SRBC) binding. The concentration of antibody used in our assay appears to highlight the RA-control differences--suggesting a possible qualitative difference in EA-binding capacity. We find no correlation between EA binding and disease duration or rheumatoid factor titre. The assay is susceptible to technical variation, and the effects of antibody concentration, lymphocyte to SRBC ratio, method of blood collection and lymphocyte-separation procedure have all been evaluated.
4081662 Plasma amino acids in rheumatoid arthritis. 1985 Plasma amino acid concentrations have been investigated in 12 female patients with rheumatoid arthritis (RA), who were hospitalized for two 14-day periods, one of which included 7 days of total fasting, whereas the other served as control period with normal food intake. All medical treatment was stopped on admission to the hospital. Plasma amino acid levels were repeatedly determined during both periods. Another group, consisting of 8 healthy volunteers, also underwent total fasting, for 6 days. The response to food deprivation with regard to plasma amino acid levels was compared with that in the RA patients. The results obtained from the control period were compared with those derived from age and sex matched healthy controls. RA disease was not characterized by a typical amino acid pattern. Major increases were seen in the concentrations of taurine, aspartate, glutamate, glycine, 1-methyl histidine, isoleucine and arginine. Rather smaller yet significant elevations could be observed in the levels of cystein, threonine, serine, citrulline, methionine and leucine. The only amino acid to show a lowered concentration was alpha-aminobutyrate. Most of the alterations induced by fasting were similar to those in healthy volunteers. An exception was the levels of taurine, which evidenced in RA patients a further increase during starvation, not observed in healthy volunteers, and valine which exhibited, a smaller increment than that apparent in healthy controls. The increase in sulphur-containing amino acids might be interpreted as a sign of an enhanced glutathione (GSH) catabolism, whereas the differing metabolic behaviour of branched chain amino acids (BCAA) suggests a specific reaction of valine in RA disease, similar to that in other catabolic diseases.
6708845 Do we get too much iron? 1984 Jan Iron in hemoglobin of 14 gm/100 ml, which is considered normal, may predispose to malignancies and to rheumatoid, heart, bacterial and other infective diseases. Conversely, a mild state of iron-deficiency anemia as presented by hemoglobin of 10 gm/100 ml may be an affordable price for protection from these disease states. The harm due to too much iron is discussed.
919558 [Rheology and hyaluronic acid in inflammatory joint effusions (author's transl)]. 1977 Nov 11 The Weissenberg rheogoniometer was used to measure viscosity, normal force and the number of molecular entanglements, calculated from a shear modulus obtained by prestationary experiments, in inflammatory and non-inflammatory synovial fluid effusions. The rheological properties show greater pathological change in the inflammatory synovial fluid samples than in the non-inflammatory. Variation in the hyaluronic acid concentration is only partly responsible for the pathological rheology. Initial experiments with a normalization method for the viscosity flow curves suggest the possibility of determining changes in polymerization or structure of the hyaluronic acid by rheological measurements.
6090311 The inactivation of the polymorphonuclear leukocyte by non-steroidal anti-inflammatory dru 1984 Jun When human neutrophils (PMNs) are activated by appropriate stimuli, they aggregate, generate superoxide anion (O2-) and secrete lysosomal enzymes. Pre-incubation of PMNs in vitro with the cyclo-oxygenase (COx) inhibitor piroxicam (50 microM) before stimulation with the chemotactic peptide f-met-leu-phe (FMLP, 10(-7)M) inhibited all of these responses. The COx inhibitor ibuprofen inhibited FMLP-induced aggregation and lysozyme secretion, leaving O2- generation unaffected. Binding of 3H-FMLP was inhibited by piroxicam. When the plant lectin concanavalin A (Con-A, 30 micrograms/ml) or the tumor promoter phorbol myristate acetate (PMA, 50 micrograms/ml) was used as a stimulus, ibuprofen had no effect on PMN response, while piroxicam inhibited only O2- generation. To determine whether such inhibition might also occur in vivo, we tested neutrophil aggregation and O2- generation in response to FMLP in 26 normal subjects. These subjects were then administered therapeutic doses of piroxicam (20 mg/day), ibuprofen (2400 mg/day) or indomethacin (100 mg/day), and neutrophil functions were retested after 3 days. Piroxicam inhibited FMLP-induced aggregation by 31% (5.2 cm2/min versus 3.6 cm2/min, P less than 0.004) and O2- generation by 35% (15.8 nmol cytochrome c reduced versus 10.2 nmol, P less than 0.002). Ibuprofen inhibited FMLP-induced aggregation by 44% (5.2 versus 3.0, P less than 0.03) but had no effect on O2- production. Indomethacin inhibited FMLP-induced aggregation (6.4 versus 2.9, P less than 0.01) but had no effect on O2- generation.(ABSTRACT TRUNCATED AT 250 WORDS)
7384725 [Tiopronine: new basic treatment for rheumatoid arthritis. Open study of 158 cases]. 1980 Mar A study of patients with rheumatoid arthritis permitted us to note the interest of tiopronine (sulfhydryl compound of the d-penicillamine type) in the basic treatment of rheumatoid arthritis. The dose of the drug was on average, 1 gram daily, which, in one series of patients, was administered at the start of treatment and in another series, with an increase of dosage of 250 mg every 20 days. The results, judged by the reduction of the Ritchie and Lee index, of the E.R.S. and the steroid and non-steroid anti-inflammatory requirements, are good (very good and good) in 47% of cases. These patients were in an advanced stage of the disease and there had been numerous therapeutic failures. Side effects similar to those observed during treatment with D-penicillamine were present in 38% of cases, and in 31% required stopping treatment. It is likely that the frequency of stopping treatment for side effects was definitely exaggerated. The place of this new drug in the basic treatment of rheumatoid arthritis requires further study by a double blind test with D-penicillamine, and this is at present in progress.
