8630631 A double-blind, three-week study to compare the efficacy and safety of meloxicam 7.5 mg an 1996 Apr A multicentre, double-blind, randomized study was conducted in patients with rheumatoid arthritis (RA) in order to compare the efficacy and safety of two different doses of meloxicam, a new preferential cyclooxygenase-2 (COX-2) inhibitor. Four hundred and twenty-three patients were randomized to receive once-daily oral meloxicam 7.5 mg (n = 216) or meloxicam 15 mg (n = 207) for 3 weeks. The Ritchie joint index and pain in the morning were significantly improved versus baseline (P < 0.001) in both groups. There were no significant differences between the effects of each dose with respect to these measures nor with respect to final assessment of global efficacy by the patients. However, the 15 mg dose was associated with a significantly (P < 0.05) better effect on morning stiffness and grip strength. No differences between the doses were observed with regard to the other secondary efficacy parameter (pain at night, body weight and erythrocyte sedimentation rate). Both doses of meloxicam were well tolerated. There were no differences between the doses with respect to global tolerance as assessed by the patient and the patients, 'general condition'. In conclusion, meloxicam at a once-daily dose of either 7.5 or 15 mg is well tolerated and effective in the treatment of patients with RA.
7983641 Decreased testosterone levels in men with rheumatoid arthritis: effect of low dose prednis 1994 Aug OBJECTIVE: To determine whether men with rheumatoid arthritis (RA) have abnormal hypothalamic-pituitary-gonadal axis function and to measure the effects of low dose prednisone therapy in these patients. METHODS: We measured testosterone, follicle stimulating hormone (FSH), and luteinizing hormone (LH) in 36 men aged 38-75 (mean age +/- 1 sd = 62 +/- 10 years) who had longstanding active RA (mean disease duration = 17 +/- 12 years) and in 70 healthy elderly male controls, aged 53-83 (mean age 68 = +/- 6 years). We divided the group with RA into those taking no prednisone (n = 12) and those taking 5 to 10 mg/day of prednisone (n = 24) and analyzed these groups separately to determine whether low doses of prednisone affected testosterone levels. RESULTS: Compared to the healthy controls, patients with RA not taking prednisone had normal testosterone levels but significantly elevated levels of FSH and LH (p < 0.01 for both comparisons). In contrast, patients with RA taking prednisone had significantly lower testosterone levels (p < 0.05), but levels of FSH and LH were only slightly elevated compared to controls. Compared to patients not taking prednisone, patients taking prednisone had lower levels of testosterone, FSH, and LH. CONCLUSION: Male patients with RA who are not taking prednisone have significantly elevated levels of FSH and LH with normal testosterone levels, suggesting a state of compensated partial gonadal failure. Male patients with RA taking low doses of prednisone have lower testosterone and gonadotropin levels, suggesting that prednisone may suppress the hypothalmic-pituitary-testicular axis. Since testosterone affects immune function as well as bone and muscle metabolism, androgen deficiency in some men with RA may predispose these patients to more severe disease and to increased complications of steroid therapy such as myopathy and osteoporosis.
1393370 Detection of cytokines at the cartilage/pannus junction in patients with rheumatoid arthri 1992 Oct Cytokine release at the cartilage/pannus junction (CPJ) may be involved in cartilage destruction and tissue repair in rheumatoid arthritis (RA). Tissue samples of CPJ from 12 RA patients were examined for the presence of cytokines using immunohistochemical techniques with immunoaffinity purified F(ab')2 antibodies raised against recombinant human cytokines. Twenty-four areas of distinct CPJ at which a discrete junction between cartilage and overlying pannus exists were observed. In all specimens, tumour necrosis factor (TNF)-alpha, interleukin (IL)-1 alpha. IL-6, granulocyte-macrophage colony-stimulating factor (GM-CSF) and transforming growth factor (TGF)-beta 1 were detected in cells in pannus particularly along the surface of cartilage and at the site of cartilage erosion. Double immunofluorescence staining showed that most cytokine containing cells also labelled with a macrophage marker (CD68). About 50% of blood vessel endothelial cells stained for GM-CSF. Twelve areas of diffuse fibroblastic CPJ, at which an indistinct margin is seen between cartilage and pannus were examined. At this site, TGF-beta 1 was the only cytokine detected in fibroblast-like cells. None of these cytokines were detected in synovial tissue at the normal synovium/cartilage junction. Chondrocytes from all 11 normal specimens as well as those from RA patients stained for IL-1 alpha, TNF-alpha, IL-6, GM-CSF and TGF-beta 1, especially those close to subchondral bone. However, IL-1 beta, interferon-gamma and lymphotoxin were not detected in either the normal synovium/cartilage junction or rheumatoid CPJ.(ABSTRACT TRUNCATED AT 250 WORDS)
7553041 [Case report: rheumatoid arthritis complicated by chronic myelogenous leukemia treated wit 1995 Feb A fifty-six-year old man complained of arthralgia and swelling of both feet, morning stiffness in both hands and finger joints in March 1987, and was treated with non-steroidal anti-inflammatory agents at another hospital. He has been treated for chronic myelogenous leukemia (CML) since May 1990. He was admitted to our hospital in March 1991 because of worsening of his multiple arthralgias, and a diagnosis of rheumatoid arthritis (RA) (Stage I, Class 2) was made on the basis of gait disturbance, arthralgia persisting for more than 6 weeks, the presence of subcutaneous nodules and X-ray findings. CML was confirmed by peripheral blood and bone marrow findings and the presence of the Philadelphia chromosome and bcr gene rearrangement. High fever and dyspnea developed suddenly 3 days after administration of interferon in May 1991. In addition to pneumonia, a leucostasis was suspected and he was treated with high dose steroids and antibiotics. After improvement, the steroids were tapered and he was discharged from hospital in July 1991.
1306600 [Comparative efficacy of ketoprofen related to the route of administration (intramuscular 1992 Nov 30 Evidence of the analgesic effects of nonsteroidal antiinflammatory drugs in human diseases is easy to collect. However, demonstration of differences in the activity of NSAIDs according to the route of administration is considerably more difficult. Forty patients with rheumatoid arthritis were given either one intramuscular injection of 100 mg ketoprofen with two placebo capsules or one intramuscular injection of placebo with two 50 mg ketoprofen capsules. Analysis of changes in pain severity over the six-hour study period failed to disclose any statistically significant differences between the two groups. However, time to peak effectiveness (Tmax) was significantly shorter with the intramuscular route (194 +/- 118 minutes) than with the oral route (276 +/- 111 minutes) (p = 0.029). Although intramuscular NSAID therapy is rarely warranted in RA patients, these findings suggest that RA may serve as a clinical model for evaluating the effectiveness of a NSAID according to the route of administration.
8455764 The Halifax Interlaminar Clamp for posterior cervical fusion: initial experience in the Un 1993 Mar A retrospective review of patients who underwent posterior cervical stabilization with Halifax Interlaminar Clamps in four neurosurgical centers in the United Kingdom was performed. Satisfactory bone fusion without complication occurred in all patients in whom lower cervical spinal stabilization (C3-C7) was performed. Complications occurred in 14 of 45 patients undergoing atlantoaxial arthrodesis. In 10 patients, one of the screws loosened, and in 4 patients, one of the clamps disengaged; additional operations to achieve bone fusion were required in 9 patients (20%). The Halifax Interlaminar Clamp is safe and effective for posterior stabilization in the lower cervical spine; there is a significant failure rate associated with its use for atlantoaxial arthrodesis.
7818578 The role of T cell receptor beta chain genes in susceptibility to rheumatoid arthritis. 1995 Jan OBJECTIVE: To evaluate the role of the T cell receptor beta chain locus (TCRB) in genetic susceptibility to rheumatoid arthritis (RA). METHODS: Twenty-eight multiplex RA families were recruited from 3 rheumatology outpatient departments. All members were genotyped for a highly informative microsatellite (V beta 6.7), a V beta 12.2 SSCP marker, and a biallelic C beta restriction fragment length polymorphism. Data were analyzed by the SIBPAL program to assess identity-by-descent in affected sib-pairs. RESULTS: Using the V beta 12.2 marker, there was suggestive evidence of increased sib-pair sharing (P = 0.005) in affected offspring (a P value of 0.001 is generally taken to establish linkage). Data for V beta 6.7 and C beta yielded significance levels of 0.06 and 0.19, respectively. CONCLUSION: These data suggest that a gene in or linked to the TCRB complex may confer genetic susceptibility to RA in these families. Confirmation in a larger panel of families is required.
8164206 Autonomic nervous system involvement in rheumatoid arthritis. 50 cases. 1993 Sep OBJECTIVE: To investigate the involvement of the autonomic nervous system (ANS) in rheumatoid arthritis (RA), which is rarely discussed. METHODS: Fifty cases of RA were selected, excluding all patients liable to develop dysautonomia or having a treatment interfering with ANS. They were investigated by cardiovascular tests of heart rate variations in deep breathing, Valsalva maneuver and orthostatic change in posture. These quantified tests were reported as ratios: breathing, Valsalva and 30/15. A control series of 82 healthy subjects was tested to determine the abnormal threshold for each one of the 3 tests and allowed a correlative study. Dysautonomia was defined when 2 of the 3 tests were pathological. According to these criteria, 30 patients with RA with ANS dysfunction were retained. RESULTS: The clinical examination of these patients showed no neurological sign or autonomic sign but there was an inflammatory syndrome. Rheumatoid factors (RF) were frequently present as were slowly progressive articular destructions. The statistical study revealed a significant difference between the series of RA patients and the control series, only for the Valsalva maneuver (p < 0.01) and there was no obvious correlation between ANS dysfunction in RA and markers of inflammation, presence of RF, duration of disease or degree of articular destructive lesions. CONCLUSION: Our study is in agreement with the literature which reports an ANS involvement in RA with a same frequency but remaining primarily subclinical and probably isolated from other peripheral or central nervous system damage. The physiopathology of this form of dysautonomia is discussed and an immunological mechanism is suggested.
7722614 Breast implants, rheumatoid arthritis, and connective tissue diseases in a clinical practi 1995 Apr This study was designed to assess the relationship between breast implants and certain rheumatologic diseases (rheumatoid arthritis and diffuse connective tissue diseases). The study base was a rheumatological practice in Atlanta, Georgia that started in 1982 and began computerizing its records in 1985. The computerized records through May 1992 included 4229 women patients, 150 with breast implants and 721 with a diagnosis of rheumatoid arthritis (RA) and/or one of the connective tissue diseases (CTDs). Of the 721 patients who had been diagnosed as having rheumatoid arthritis (RA) and/or one of the connective tissue diseases (CTDs), 392 had rheumatoid arthritis, 344 had connective tissue disease, 15 had both rheumatoid arthritis and a connective tissue disease, and 33 had more than one connective tissue disease. Of the patients with connective tissue disease, 179 had systemic lupus erythematosus, 64 had scleroderma, 49 had Sjögren's syndrome, 36 had dermatomyositis or polymyositis, and 49 had mixed connective tissue disease. Data were analyzed by univariate and multivariate techniques including logistic regression. Significant variables included age at first visit, income strata, and period of first visit. Analyses were performed for each clinical diagnosis, for all connective tissue diseases together (CTDs), and for those with rheumatoid arthritis and/or connective tissue disease (RA/CTD). Analyses were performed on the total data base and on the records of new patients (1986-1992). The adjusted odds ratio for breast implants among women who entered the practice in 1986-1992 and were diagnosed as having rheumatoid arthritis and/or one of the connective tissue diseases (RA/CTDs) was 0.45 (0.22-0.90), for those with rheumatoid arthritis was 0.61 (0.28-1.49), for those with any of these specific diffuse connective tissue diseases was 0.34 (0.11-1.06) compared to those without the disease. For systemic lupus erythematosus, the odds ratio of 0.24 (0.03-1.75) was based on a single case who had the disease 5 yr before the implant. For Sjögren's syndrome, the odds ratio was 1.67 (0.39-7.13) based on two cases, one of whom had the disease 5 yr before the implant. The calculated odds ratios for scleroderma, dermatomyositis/polymyositis, and mixed connective tissue disease were zero since no cases were diagnosed among the patients with breast implants. This study found no evidence that women with breast implants are at an increased risk for having rheumatoid arthritis or other diffuse connective tissue disease.
8612028 A randomized double-blind controlled trial of sulphasalazine combined with pulses of methy 1996 Feb Thirty-eight patients with rheumatoid arthritis meeting American College of Rheumatism (ACR) criteria were entered in a randomized controlled trial (RCT) of 6 months to assess whether monthly treatment with i.v. methylprednisolone (MP) enhances or accelerates the efficacy of sulphasalazine (SSZ). All patients had failed at least one second-line agent and were randomized to receive SSZ (2g/day) and pulses of MP (5 mg/kg), or SSZ+ (2 g/day) and pulses of saline (SA). A single infusion of 2 h was carried out in both groups for a total of three times (0, 1 and 2 months). The two groups were comparable at baseline regarding their demographic and clinical characteristics. Disease activity was evaluated every 2 months by means of: (1) joint count; (2) morning stiffness; (3) grip strength; (4) visual analogue pain score; (5) health assessment questionnaire; and (6) erythrocyte sedimentation rate. All outcome measures improved significantly in both groups (P < 0.001). Evaluation at each follow-up visit showed no significant differences between the groups in any of the adverse effects attributable to SSZ therapy (one SA vs two MP). Adverse effects attributable to SA/MP therapy were rare and mild. We concluded that repeated pulses of MP during the first 3 months of treatment did not improve the efficacy of SSZ. Therefore, there is no justification for using MP in this way during the induction phase of SSZ therapy.
7920523 [Estimation of benefits and risks of the treatment of rheumatoid polyarthritis with glucoc 1994 Apr The purpose of this study was to use the utility approach to evaluate the risks and benefits of corticosteroid therapy in rheumatoid arthritis patients. The utility approach provides us with a quantitative measure of the value or preference a patient attaches to his overall health status defined on a scale from perfect health (1) to death (0). Benefits and toxicity are combined into a number reflecting the patients combined assessment of the benefits of treatment and the side-effects associated with it. Utility of 3 scenarios (rheumatoid arthritis patients treated respectively with no, 5 mg/day and 15 mg/day of prednisone) were determined through the time trade-off (TTO) and thermometer scale (TS) techniques. Twenty-five rheumatoid arthritis patients selected at random among subjects attending an outpatient clinic and 25 rheumatologists were interviewed using visual aids. Treatment with 15 mg/d prednisone was assigned the highest utilities by both patients and physicians. Coefficients of correlation between thermometer scale and time trade-off utilities were 0.675 (p < 0.01) for physician-assigned utilities and 0.518 (p < 0.05) for patient-assigned utilities. Medical decisions concerning rheumatoid arthritis patients should take into account the preferences of patients and physicians.
1613619 Adult-onset Still's disease with a significant rheumatoid factor: examining proper use of 1992 May A case is presented of a 32-year-old man with classic clinical adult-onset Still's disease, who had an initially elevated (1:320) but not persistently high rheumatoid factor. Since lack of a high rheumatoid factor is one feature in the proposed classification criteria for adult-onset Still's disease, the patient was given a diagnosis of rheumatoid arthritis. The faulty reasoning behind this diagnosis of rheumatoid arthritis is discussed, focusing on the inappropriate use of classification criteria for individual clinical diagnosis, as well as the occasional need for longitudinal diagnosis.
8974919 [Analysis of linkage of HLA antigens and rheumatoid arthritis]. 1996 Jul Based on consistent associations of rheumatoid arthritis (RA) with some HLA antigens several authors hypothesized the existence of a gene of susceptibility to RA, linked closely with the HLA loci and in disequilibrium with associated alleles. Data on six pedigrees (four of these involved three generations) with recurrent diseases (in total, 45 individuals, 13 of whom were affected with RA) were used in the linkage analysis. The data on allelic typing of HLA-A and -B loci were combined to form a "superlocus" that enabled more accurate determination of an individual genotype for the marker. Previously obtained parameters of disease inheritance were used to test the locus: a frequency of the abnormal allele of 2.14%, and the penetrances of abnormal homozygotes, heterozygotes, and normal homozygotes of 100, 2.1, and 0% in men and 100, 6, and 0.3% in, respectively. A softwares package developed in the Department of Epidemiology and Genetics of the Institute of Rheumatology, Russian Academy of Medical Sciences, was used in the linkage analysis. This work resulted in two-dimensional tables of Lod score values at different recombination frequencies (RF), changing with a step of 0.05 in men and women. The minimal Lord score value at RF = 0 is -2.11, which is higher than the critical value (-2.0) and serves as an indication of the absence of close linkage between the analyzed loci.
8052924 [Recombinant human erythropoietin (KRN5702) therapy for autologous blood transfusion in pa 1994 Jun In order to evaluate the effect of recombinant human erythropoietin (rHuEPO) on autologous blood transfusion in patients with rheumatoid arthritis (RA), we performed a phase II clinical trial in 65 RA patients undergoing elective surgery. rHuEPO was administered subcutaneously once a week and after observing erythropoiesis, autologous blood was collected. Fifty-seven of the 58 patients who completed treatment responded to rHuEPO and could donate more than 400 ml of autologous blood. Among them, 23 out of 28 patients undergoing total hip arthroplasty, 27 out of 28 undergoing total knee arthroplasty and 1 out of 1 undergoing spinal surgery did not need homologous blood transfusion perioperatively. During rHuEPO treatment, no significant changes of clinical parameters of RA activity were observed. Two patients discontinued the treatment because of mild and transient side effects. These results indicate that subcutaneous rHuEPO is safe and effective in eliminate the need for homologous blood transfusion, even in anemic RA patients undergoing elective orthopedic surgery.
8774167 Further evidence for genetic anticipation in familial rheumatoid arthritis. 1996 Jul OBJECTIVE: To determine whether preliminary evidence supporting features of genetic anticipation in familial rheumatoid arthritis (RA) could be replicated in independent and larger samples. METHOD: Data were obtained from records of 59 multicase families from the Arthritis and Rheumatism Council (ARC) National Repository in Manchester, 65 multicase families from Cleveland, Ohio, USA, and 253 consecutive patients with RA attending clinics in Nottingham. RESULTS: Mean ages of disease onset in the parents affected with RA were consistently greater than those in the probands. In the ARC data, the mean age difference in disease onset between the affected mother and proband pairs was 16.0 years (95% confidence interval (CI) 7.2 to 24.8 years, n = 11); in the Cleveland data it was 7.8 years (95% CI 0.9 to 14.7 years, n = 24), and in the Nottingham data it was 10.4 years (95% CI 2.8 to 18.0 years, n = 28). Similar results were found in the limited number of father-proband pairs. Unlike the findings of earlier work, there was no correlation between proband age at disease onset and age of the parent at conception of the proband. CONCLUSION: In independent and larger familial RA data sets, features of genetic anticipation were replicated. Our findings support the case for further research at a molecular level into genetic anticipation in those families with two successive generations affected by RA.
8147927 Association of TAP2 polymorphism with rheumatoid arthritis is secondary to allelic associa 1994 Apr OBJECTIVE: To study polymorphisms of the newly described TAP2 locus in rheumatoid arthritis (RA) and to analyze their relationship with HLA-DRB1 alleles previously implicated in the development of the disease. METHODS: TAP2 polymorphic residues at 3 sites, Val/Ile-379, Ala/Thr-565, and Ala/Thr-665, were characterized by amplification refractory mutation system polymerase chain reaction in 185 RA patients and 48 HLA-DR4 positive healthy controls. HLA-DR4 subtypes were determined by sequence-specific priming and oligonucleotide hybridization. RESULTS: The frequencies of Ile-379, Thr-565, and Thr-665 were significantly increased in DR4 positive versus DR4 negative RA patients. TAP2 genotype distributions also differed between the patient groups stratified by DR4 status. However, no significant differences in TAP2 polymorphisms were observed between DR4 positive RA patients and DR4 positive controls, although relationships between specific DR4 subtypes and TAP2 variants were identified. CONCLUSION: Particular TAP2 polymorphisms are associated with distinct HLA-DR specificities in both normal and RA populations. Thus, the prevalence of specific TAP2 residues and genotypes in RA appears to be secondary to the HLA-DR frequencies and genotypic combinations that are typical of RA.
1617896 Management of proteinuria secondary to penicillamine therapy in rheumatoid arthritis. 1992 Jun To determine if a policy of continuing penicillamine therapy in successfully treated patients with rheumatoid arthritis in the presence of persistent proteinuria, was associated or not with resolution of this adverse effect, a computer record of patients receiving penicillamine for rheumatoid arthritis was searched for patients with persistent proteinuria and the case notes of these patients reviewed. Eleven patients with persistent proteinuria were identified, eight of whom did not have nephrotic syndrome and were continued on penicillamine with close monitoring. In 5 patients proteinuria resolved after 16-21 months; 3 developed peripheral oedema (2) or worsening of pre-existing hypertension and proteinuria (1). In one of these the proteinuria subsequently resolved and one died of unknown cause. Of the 3 initially nephrotic patients, two had resolved at the time of the study. Persistent proteinuria in penicillamine-treated patients with rheumatoid arthritis resolves with continued therapy in the absence of nephrotic syndrome but vigilance is required for the development of any complications.
8468730 Total ankle replacement: preliminary report of 3 cases. 1993 Jan Total Ankle Replacement has been quite limited used currently and ankle arthrodesis is still the treatment of choice for most disabling arthritic disease of the ankle because of the generally poor long term results of ankle replacement. In spite of its popularity, ankle arthrodesis has many disadvantages, including long immobilization, high pseudoarthrosis rate, and load shift with increased stress on the neighboring joints of ankle. Total ankle replacement may be tried on some selected cases, such as on older patients or on patients with bilateral ankle lesions, multiple joints involved arthritis, such as rheumatoid arthritis etc. This paper reports three ankle replacements with a two year follow up, and they all have encouraging short term results. In the future, the development of a more effective ankle replacement seems to be likely. But at the present time, only carefully choosing the available prosthesis and strictly selecting the indicated patient can make the total ankle replacement acceptable.
8450614 [Primary splenic lymphoma complicated by malignant rheumatoid arthritis and bladder cancer 1993 Jan A 64-year-old man had been found to have primary splenic lymphoma (stage III) seven years after the diagnosis of rheumatoid arthritis (RA). Histological diagnosis of the lymphoma was diffuse, medium sized cell type (LSG) or intermediate lymphocytic lymphoma (ILL). Splenectomy and ten courses of CHOP regimen produced continuing remission. After tow years, he suffered from peripheral neuropathy due to vasculitis of polyarteritis nodosa (PN) type. He was treated with prednisolone (PSL) and cyclophosphamide (CPM) for malignant rheumatoid arthritis. One year later, evaluation for intermittent hematuria revealed bladder cancer and he underwent total cystectomy. He has been treated with small doses of PSL under observation. The high incidence of ILL in lymphomas developing in patients with autoimmune diseases of the thyroid and salivary glands has been reported. This case suggests an association between antecedent RA and splenic lymphoma, the influence of splenectomy and chemotherapy on occurrence of rheumatoid vasculitis, and a causal relationship between CPM and bladder cancer.
8244590 The Blauth total knee endoprosthesis. Eighteen years' experience in practice. 1993 Aug A distinction must be drawn between the older constrained prostheses, in which load was transferred via metal-coated hinges, and later models using the low-friction principle, where the axle is not load bearing. The latter show good long-term results. The greater stability of constrained prosthesis allows earlier and less complicated mobilization even of elderly patients.
