What factors influence functional ability in patients with rheumatoid arthritis. Do they alter over time?

OBJECTIVES: To describe the changes in functional ability (FA) taking place over 5 yr in patients with rheumatoid arthritis (RA) starting disease-modifying anti-rheumatic drug (DMARD) therapy, to investigate the factors having most influence upon FA and to compare these factors at baseline and after 5 yr of treatment. METHODS: Three hundred and sixty-six patients with active RA were studied as part of a 5-yr randomized controlled study of DMARD therapy. FA was assessed by Health Assessment Questionnaire (HAQ) score every 6 months. Multiple linear regression was used to identify factors affecting FA at baseline and at 5 yr. The independent variables used were age, sex, visual analogue scale (VAS) pain, Ritchie articular index, C-reactive protein (CRP), Larsen score and log-transformed morning stiffness (EMS). RESULTS: Mean HAQ score was 1.64 at baseline, improved by 21% at 1 yr and gradually returned towards baseline levels by 5 yr. At baseline only 34% of variance in HAQ score could be explained; the most significant explanatory variables were the Ritchie articular index and CRP. At 5 yr the variance explained was 60%. The Ritchie articular index remained the strongest factor followed by VAS pain, log(10) EMS and Larsen score. CONCLUSIONS: Improvement in function did occur after commencement of the first DMARD therapy but was not maintained to 5 yr. The most consistent factor affecting function was joint tenderness. Global pain and duration of EMS were of lesser importance. Disease activity measures such as the CRP exerted an influence in the earlier, more active stages of disease: radiographic damage assumed greater importance as the arthritis progressed.     

An open, controlled, randomized comparison of cyclosporine and azathioprine in the treatment of rheumatoid arthritis: a preliminary report

Cyclosporine (10 mg/kg/day) and azathioprine (2.5-3 mg/kg/day) were compared for 26 weeks in an open, controlled, randomized study of 24 patients with rheumatoid arthritis. Each treatment group consisted of 12 patients. Those patients who took cyclosporine improved significantly in the 50-foot walk time, circumferences of proximal interphalangeal joints, Ritchie articular index, global assessment by investigator, and grip strength, when compared with baseline findings. In the azathioprine group, there was improvement only in grip strength.     

The safety and efficacy of cyclosporine (Neoral) in rheumatoid arthritis.

OBJECTIVE: To assess the safety and efficacy of cyclosporine (Neoral), its steroid sparing effect, and its usefulness in combination therapy with methotrexate (MTX) in the treatment of refractory rheumatoid arthritis (RA). METHODS: All patients given cyclosporine for refractory RA over a 21 month period were included in an open, prospective study. Patients were reviewed initially fortnightly then monthly with clinical evaluation and serum creatinine. There were no restrictions on the use of other disease modifying agents, nonsteroidal antiinflammatory drugs, or corticosteroids. RESULTS: Forty-six patients with severe RA were included in the study, 33 (72%) female and 13 (28%) male, with a mean age of 54.8 years (range 20-74). At the completion of the study 30 (65%) were still taking cyclosporine at a mean dose of 2.94 mg/kg/day for a mean duration of 10.5 months. Thirteen patients discontinued cyclosporine due to side effects, most commonly gastrointestinal, and 3 due to inefficacy. Thirty-seven of the 46 patients were taking prednisolone at the start of the study at a mean dose of 10.36 mg/day, which decreased to 7.068 mg/day at the end of the study (p < 0.001). Thirty patients used cyclosporine in combination with MTX. The mean dose of MTX decreased from 15.08 to 13.67 mg/wk (p = 0.02). The mean serum creatinine increased by 13% from 74 to 83.7 micromol/l. Patients who continued therapy had a shorter duration of disease, with a mean of 9.93 years compared to 15.73 years in those who stopped therapy (p = 0.004). CONCLUSION: Cyclosporine (Neoral) was a safe and effective therapy in this population of patients with RA refractory to standard therapy. We observed a significant steroid sparing effect and have shown that combination therapy with MTX does not increase side effects and allows for a decrease in MTX dose. Renal function is not adversely affected if guidelines are followed.     

Cyclosporine in rheumatoid arthritis.

The efficacy and toxicity of cyclosporine in the treatment of patients with rheumatoid arthritis (RA) are reviewed. Most of the early trials were restricted to patients with intractable RA. The initial daily dose of cyclosporine was 5 to 10 mg/kg, which is now considered high. Of 283 cyclosporine-treated patients in nine studies, 8% discontinued the drug prematurely because of inefficacy and 17% because of adverse reactions. Cyclosporine improves clinical parameters but does not influence the erythrocyte sedimentation rate. The most important side effects are gastrointestinal intolerance and nephrotoxicity. The former is of minor importance with the present dosage schedule (starting daily dose, 2.5 mg/kg), and increments should follow the principle "go low, go slow." Guidelines are given to avoid or reduce nephrotoxicity. It may be beneficial to administer cyclosporine early in the course of RA.     

A clinical study of CPH 82 vs methotrexate in early rheumatoid arthritis

OBJECTIVES: The objectives of this study were to evaluate the therapeutic efficacy of CPH 82 in comparison with methotrexate (MTX) in adult patients with early, active rheumatoid arthritis (RA) and to compare the tolerance and safety profiles of the two drugs. METHODS: The study was a 24-week, double-blind, randomized study in 10 centres of 100 patients with active RA, with a disease duration of less than 2 yr at the start of treatment, which consisted of either CPH 82 300 mg/day or MTX 10 mg/week. The six primary effect variables were: number of swollen joints, Ritchie's articular index, patient's pain score, patient's global score, Health Assessment Questionnaire (HAQ) and C-reactive protein (CRP). Erythrocyte sedimentation rate (ESR), physician's global score and the efficacy according to the European League Against Rheumatism (EULAR) and American College of Rheumatology (ACR) response criteria were also analysed. RESULTS: There was a significant improvement for both drugs in all variables. Significant differences between the drugs in favour of MTX were found only in patient's pain score, CRP and ESR. By the EULAR criteria, 76% and 86% were judged to be responders in the CPH 82 and MTX groups, respectively. By the ACR criteria, the corresponding figures were 58% and 64%. The most common side-effects were gastrointestinal, which were similar in both groups. The numbers of treatment failures due to adverse events were two with CPH 82 and 14 with MTX. CONCLUSIONS: The clinical effect of CPH 82 in this study was comparable to that of MTX at a dose of 10 mg/week. Both drugs reduced acute-phase reactants, MTX more effectively than CPH 82. The safety profile of CPH 82 was more favourable than that of MTX without folic acid supplementation.     

In vitro migration of mononuclear cells towards synovial fluid and plasma from rheumatoid arthritis patients correlates to RANTES synovial fluid levels and to clinical pain parameters

OBJECTIVE: To evaluate in vitro migration of mononuclear cells towards synovial fluid (SF) and plasma in relation to RANTES synovial fluid levels and clinical disease activity. METHODS: 31 RA patients with synovitis in one knee were included. Modified Boyden chamber technique was used to determine a migratory index defined as: 'In vitro migrating cells towards SF' divided by 'In vitro migrating cells towards plasma'. RANTES was quantified by ELISA. Disease activity was assessed by the swollen joint count, the Ritchie articular index (RAI), global assessment, pain on VAS, HAQ, ESR and CRP. RESULTS: A positive significant correlation was found between the migratory index and the RANTES levels in SF (r=0.48, p=0.006), the RAI (r=0.56, p=0.0001) and pain on VAS (r=0.43, p=0.04). The in vitro migration could be inhibited in 3 of 4 SF samples by neutralising antibodies towards RANTES (12-18%). CONCLUSION: The migratory index correlate to SF levels of RANTES and parameters for joint pain.     

Prospective evaluation of the frequency and clinical significance of antineutrophil cytoplasmic and anticardiolipin antibodies in community cases of patients with rheumatoid arthritis

OBJECTIVES: To evaluate the frequencies of antineutrophil cytoplasmic (ANCA), anticardiolipin (aCLA) and anti-beta(2)-glycoprotein 1 antibodies (abeta(2)-GP1A) in rheumatoid arthritis (RA) of limited duration in patients recruited primarily from private practitioners (80%), and to attempt to correlate the presence of these antibodies with certain clinical and/or biological criteria. Patients and methods. Patients (n = 102) with RA evolving for <5 yr (mean 2.2 yr) were recruited. A home evaluation collected clinical data [Ritchie articular index, Health Assessment Questionnaire (HAQ) index, extra-articular manifestations] and blood for biological analyses [C-reactive protein (CRP), rheumatoid factor, ANCA, aCLA, abeta(2)-GP1A]. ANCA were detected by indirect immunofluorescence on neutrophils and their specificity was determined by enzyme-linked immunosorbent assay (ELISA) and confirmed by immunoblotting; aCLA and abeta(2)-GP1A were detected by ELISA. RESULTS: Patients had mild RA (Ritchie = 11/78 +/- 9.6; HAQ = 0.79/3 +/- 0.7), probably due to the recruitment procedure. ANCA, aCLA and abeta(2)-GP1A frequencies were 18.5, 7 and 0%, respectively. Titres of ANCA and aCLA were low. A perinuclear ANCA staining pattern was exclusively observed and lactoferrin was shown to be the major antigen recognized. No relationship was found between ANCA and aCLA and/or rheumatoid factor, or any clinical manifestations. ANCA were more common in RA of longer duration (cut-off: 4 yr; P = 0.05) and aCLA were correlated with the CRP level (P = 0.05). CONCLUSIONS: In RA of recent onset, ANCA and aCLA were detected at low titres and frequencies, and were not associated with any clinical manifestations. A longitudinal study is needed to determine whether their early appearance is predictive of subsequent disease severity.     

Radiologic evidence of disease modification in rheumatoid arthritis patients treated with cyclosporine. results of a 48-week multicenter study comparing low-dose cyclosporine with placebo

Objective. To evaluate the therapeutic efficacy of 46 weeks of treatment with cyclosporine (5 mg/kg/day) in patients with rheumatoid arthritis (RA). Methods. A 48-week randomized, double-blind, placebo-controlled, multicenter study of cyclosporine was conducted in 122 patients with active RA. Patients were evaluated by objective and subjective clinical and radiologic measurements at baseline and at the end of the study. Results. Statistically significant improvement and clinically important changes were seen for the number of tender joints, number of swollen joints, pain score, duration of morning stiffness, and Lee's functional index in the cyclosporine-treated group at the end of the study. Radiographic examination showed that cyclosporine was capable of retarding joint destruction. In the cyclosporine-treated group, serum creatinine levels increased by 17.5 μmoles/liter (23%) at week 24 and by 21.8 μmoles/liter (26%) at week 48. There was no significant difference in mean serum creatinine levels in patients treated with cyclosporine alone and those treated with cyclosporine plus nonsteroidal antiinflammatory drugs. Five patients had to be treated with antihypertensive drugs, and 2 patients were withdrawn from the study because of increased serum creatinine. Conclusion. The study shows that cyclosporine seems to have disease-modifying effects in RA.     

Cyclosporin treatment for rheumatoid arthritis: a placebo controlled, double blind, multicentre study.

The efficacy and safety of cyclosporin for patients with rheumatoid arthritis (RA) were assessed in a six month double blind, placebo controlled, multicentre study. The initial dosage of the drug was 10 mg/kg daily for two months. There were many discontinuations in both the cyclosporin group (eight out of 17) and the placebo group (six out of 19). Of the patients who completed the six months of therapy, those who had received cyclosporin showed a significant improvement in the number of swollen joints, the Ritchie articular index, and pain at active movement and at rest, compared not only with their condition at the start of the study, but also with the end results of the placebo group. Major adverse reactions to the drug were gastrointestinal disturbances and nephrotoxicity, which were probably due to the relatively high dosages of cyclosporin given in combination with non-steroidal anti-inflammatory drugs.     

Tolerance of cyclosporine A in children with refractory juvenile rheumatoid arthritis

In an open trial, tolerance and safety of cyclosporine A was studied in 14 patients with refractory juvenile rheumatoid arthritis (JRA). The doses varied from 4-15 mg/kg/day. Treatment lasted for greater than 12 months in 11 and 6 to 9 months in 3 patients. Eleven patients were withdrawn due to lack of efficacy (4) or side effects (7). A drop of greater than 2 g/l in hemoglobin and a marked rise in serum creatinine were the cause of withdrawal in 5 patients. The effect of cyclosporine on disease activity seemed to be mainly symptomatic and temporary. Probably, the dose should be kept below 5 mg/kg/day. Future controlled studies should be aware of a risk of aggravation of anemia in children treated with cyclosporine.     

Serum matrix metalloproteinase 3 levels during treatment with sulfasalazine or combination of methotrexate and sulfasalazine in patients with early rheumatoid arthritis

OBJECTIVE: To determine the effects of treatment with sulfasalazine (SSZ) or the combination of methotrexate (MTX) and SSZ on serum matrix metalloproteinase 3 (MMP-3) levels in patients with early rheumatoid arthritis (RA). METHODS: Eighty-two patients with early RA (symptoms < 1 year and DMARD-naive at presentation) were selected who had been treated with SSZ (2000 mg/day) or with the combination of MTX (7.5-15 mg/week) and SSZ. Serum MMP-3 levels, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), swollen joint count (SJC), tender joint count (TJC), Ritchie articular index (RAI), and the Disease Activity Score (DAS) were determined at 4 week intervals during a followup of 28 weeks for each treatment group. Response was based on clinical grounds and CRP at 12, 20, and 28 weeks. RESULTS: SSZ responders (n = 52) had lower baseline values of serum MMP-3, CRP, and ESR, compared to partial/nonresponders (n = 30), but did not differ in joint scores and DAS. In the SSZ responder group all variables decreased. In the SSZ partial/nonresponders, CRP, ESR, and SJC decreased in contrast to serum MMP-3, TJC. RAI, and DAS-3. After addition of MTX all variables decreased in 24 of the 30 patients who had shown a partial or no response taking SSZ. In the SSZ responders there was a delayed decrease in serum MMP-3 compared to CRP. CONCLUSION: Serum MMP-3 levels decrease in patients with early RA who respond to SSZ or to the combination of MTX and SSZ. In patients who respond to SSZ the changes in serum MMP-3 levels indicate a delayed response compared to CRP.     

Clinical Response Does Not Correlate with Intestinal or Blood Cyclosporine Concentrations in Patients with Crohn's Disease Treated with High-Dose Oral Cyclosporine

Objective : High-dose (>5 mg/kg/d) oral cyclosporine may be effective treatment for Crohn's disease, whereas low-dose oral cyclosporine (≤5 mg/kg/d) is not. This study determined the correlation between blood and intestinal tissue cyclosporine concentrations and clinical response in patients with Crohn's disease treated with cyclosporine 8 mg/kg/day. Methods : Twelve patients with inflammatory Crohn's disease were treated for 6 wk with oral cyclosporine 8 mg/kg/day, adjusted to a whole blood cyclosporine concentration (chromatography) of 200-300 ng/ml. Response was determined by the Crohn's disease activity index. Cyclosporine was measured in intestinal tissue biopsies obtained by colonoscopy at week 6 (chromatography). Results : Eight patients responded and four did not respond. There were no significant differences between the responders and non-responders in the mean whole blood or intestinal tissue cyclosporine concentrations. Similarly, there were no significant correlations between change in the Crohn's disease activity index score (baseline to week 6) and whole blood or intestinal tissue cyclosporine concentrations. Cyclosporine side effects, including nephrotoxicity and peroneal nerve palsy, were common. Conclusions: Clinical response did not correlate with whole blood or intestinal tissue cyclosporine concentrations in patients treated with high-dose cyclosporine for Crohn's disease. Cyclosporine side effects, including a significant decrease in renal function, were common.     

The side‐effects and efficacy of leflunomide in Japanese patients with rheumatoid arthritis

Aims: To investigate the efficacy and safety of leflunomide, including the side‐effects, we assessed 84 rheumatoid arthritis (RA) patients who received leflunomide treatment. Methods: We analyzed the C‐reactive protein (CRP), white blood cell count (WBC), KL‐6, and visual analogue scale (VAS) scores, modified Stanford Health Assessment Questionnaire (MHAQ) score, American Rheumatism Association score (ACR20 and ACR50) within a time course after treatment with leflunomide. We treated 84 RA patients, 12 male and 72 female from 28 to 81‐years‐old, with an average age of 63.5 years. The patients were divided into three groups: a group consisting of 38 patients who received 100 mg/day of leflunomide for 3 days followed by 20 mg/day thereafter; a second group of 11 patients who received a no‐loading dose of 10 mg/day; and a third group of 35 patients who received a no loading dose of 20 mg/day. Results: The 50% decrease of CRP seen in 2 weeks was 52% of the total of 84 patients. The WBC score did not change significantly after the medication was given. The KL‐6 score did not change significantly, either. The VAS pain score improved 4 weeks later, and then further improved 8 weeks later. Therefore, RA patients using leflunomide obtained pain relief 4 weeks after commencing medication. The MHAQ score did not change significantly until 8 weeks after the patients started the medication. ACR20 was 62% and ACR50 was 38% at 8 weeks after treatment. The side‐effects of leflunomide observed in our patients were rash, respiratory infection, diarrhea, nausea, alopecia, muscle pain, headache, dizziness and general fatigue. Twenty‐three out of 84 patients experienced side‐effects (27%), and 48/84 (57%) experienced withdrawal. In our hospital, there were no patients who developed severe interstitial pneumonia (IP) or who died after taking leflunomide; however, the incidence of side‐effects of the 100 mg/day loading dose (42.1%) was 2.5 times higher than in the patients who received 20 mg/day (17.1%) of a no‐loading dose. Conclusion: Because of this, it is possible that a 100 mg/day loading dose is a relatively high risk dose in terms of causing side‐effects, especially for severely ill RA patients with a high CRP level.     

SULPHASALAZINE IN PSORIATIC ARTHRITIS: A RANDOMIZED, MULTICENTRE, PLACEBO-CONTROLLED STUDY

A prospective double-blind, placebo-controlled, randomized studyof 24 weeks duration was carried out comparing the efficacyand tolerability of sulphasalazine (SSZ) versus placebo in patientswith psoriatic arthritis. A total of 120 patients were includedin nine centres. All patients had active disease and fulfilledthe criteria of definite psoriatic arthritis of at least 3 monthsduration. They received either SSZ (2.0 g/day) or placebo. Efficacyvariables included pain, patient's overall assessment of jointand skin improvement, morning stiffness, Ritchie articular index,ESR and CRP. An intention-to-treat (TTT) analysis was performedfor the 117 patients who qualified (three patients did not qualifydue to missing data after baseline). A per-protocol analysiswas performed for the 81 patients who completed the 6 monthsstudy period (SSZ = 38, placebo = 43). Major reasons for withdrawalwere inadequate response (SSZ = 4, placebo = 7) and adverseevents (SSZ = 8, placebo = 12). Pain was the only statisticallysignificantly different primary outcome variable at end pointin favour of SSZ in the ill analysis. No significant differenceswere present in other clinical or biological variables, althoughthere was a trend in favour of SSZ for some variables. SSZ,at a dose of 2.0 g/day, appeared to be a safe treatment in patientswith psoriatic arthritis. At this dosage, its efficacy was onlydemonstrated for the pain variable.

Subcutaneous administration of polymerized-type I collagen for the treatment of patients with rheumatoid arthritis. An open-label pilot trial

OBJECTIVE: To determine the efficacy, tolerance and safety of subcutaneous injections of porcine type I collagen-polyvinylpyrrolidone (PVP) in patients with rheumatoid arthritis (RA). METHODS: Eleven patients with active RA on stable therapy with methotrexate (MTX) were enrolled in a 3 month prospective and longitudinal study. Patients were treated weekly with subcutaneous injections of 0.2 ml of collagen-PVP (1.7 mg of collagen) in the 8 most painful joints. The primary endpoints included the Ritchie index (RI), swollen joint count, disease activity score (DAS), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP). The secondary endpoints included morning stiffness, pain intensity on a visual analog scale (VAS), and the Spanish-Health Assessment Questionnaire Disability Index (HAQ-DI). Improvement was determined using American College of Rheumatology (ACR) response criteria. RESULTS: Collagen-PVP was safe and well-tolerated and there were no adverse events. Patients had a statistically significant improvement (p < 0.05) in basal versus 3 month's treatment in morning stiffness (Delta -32.3, -68.6%), RI (Delta -10.2, -46.4%), swollen joint count (Delta -10.7, -71.8%), VAS (Delta -39.9, -63.8%), HAQ-DI (Delta -0.5, -48.5%), DAS (Delta -1.35, -70.5%) and ACR20, 50, and 70 (80.0%; 60.0% and 20.0% respectively). We found no differences in serologic or hematologic variables. CONCLUSION: Collagen-PVP was a safe and well-tolerated drug for the short term treatment of RA. The combination of collagen-PVP plus MTX was more efficacious than MTX alone. However, double-blind placebo-controlled phase II and III clinical trials are necessary to determine whether this drug could be useful in the longterm treatment of RA.     

Cyclosporine A in rheumatoid arthritis: randomized, placebo controlled dose finding study.

OBJECTIVE: To determine the lowest effective starting dose and residual benefit of cyclosporine A (CSA) in patients with rheumatoid arthritis (RA) refractory to other agents. METHODS: In a double blind (masked observer), controlled, multicenter study, patients with RA started CSA 0 (placebo; n = 61), 1.5 (n = 89), or 2.5 (n = 94) mg/kg/day in a 21 week study that permitted dose escalation after 8 weeks, 1 week tapering of dose at 16 weeks, and post-therapy observation for 4 weeks. RESULTS: Patients with RA taking CSA 2.5 mg/kg/day fared better than those in the placebo or CSA 1.5 mg/kg/day groups in Patient Global Assessment, Examiner Global Assessment, Pain/Tender Joint Count and Index, Swollen Joint Count, and the "Ability at this moment" part of a modified Health Assessment Questionnaire. There was no difference in response between CSA 1.5 mg/kg/day and placebo groups. In the CSA 2.5 mg/kg/day group: improvement occurred between 8 and 12 weeks of therapy; average CSA dose escalation resulted in CSA 2.85 mg/kg/day by Week 16; benefit was not maintained during post-therapy observation and 7 patients discontinued the study because of an adverse event. Adverse events were common in all groups and included gastrointestinal discomfort, hypertension, and increased creatinine. Adverse events remitted with adjustment of dose or after washout in most patients. CONCLUSION: In RA, treatment of patients with CSA 2.5 mg/kg/day, but not 1.5 mg/kg/day, resulted in improvement of 4 of 5 primary efficacy variables when compared to placebo. Adverse events were mostly manageable. CSA was an effective therapy for patients with RA who had failed at least one second line agent.     

Reversible nephrotoxicity of cyclosporine in rheumatoid arthritis

Irreversible nephrotoxicity has limited the use of cyclosporine in rheumatoid arthritis (RA). In a randomized clinical trial we compared 26 weeks of cyclosporine (5 mg/kg) and D-penicillamine (250 mg) treatment in 92 patients with RA with a serum creatinine less than 100 mumol/l. We adjusted the starting dose according to clinical response and side effects. During cyclosporine treatment the serum creatinine increased by median 15% (p less than 0.0001 vs baseline), quickly reversible after stopping (median followup: 1.6 years). Six patients stopped cyclosporine prematurely because of nephrotoxicity. In the D-penicillamine group the values remained at baseline.     

A randomized controlled trial of homeopathy in rheumatoid arthritis

OBJECTIVE: To test the hypothesis that homeopathy is effective in reducing the symptoms of joint inflammation in rheumatoid arthritis (RA). METHOD: This was a 6-month randomized, cross-over, double-blind, placebo-controlled, single-centre study set in a teaching hospital rheumatology out-patient clinic. The participants of the study were 112 patients who had definite or classical RA, were seropositive for rheumatoid factor and were receiving either stable doses of single non-steroidal anti-inflammatory drugs (NSAIDs) for > or =3 months or single disease-modifying anti-rheumatic drugs (DMARDs) with or without NSAIDs for > or =6 months. Patients who were severely disabled, had taken systemic steroids in the previous 6 months or had withdrawn from DMARD therapy in the previous 12 months were excluded. Two series of medicines were used. One comprised 42 homeopathic medicines used for treating RA in 6cH (10(-12)) and/or 30cH (10(-30)) dilutions (a total of 59 preparations) manufactured to French National Pharmacopoeia standards, the other comprised identical matching placebos. The main outcome measures were visual analogue scale pain scores, Ritchie articular index, duration of morning stiffness and erythrocyte sedimentation rate (ESR). RESULTS: Fifty-eight patients completed the trial. Over 6 months there were significant decreases (P<0.01 by Wilcoxon rank sum tests) in their mean pain scores (fell 18%), articular indices (fell 24%) and ESRs (fell 11%). Fifty-four patients withdrew before completing the trial. Thirty-one changed conventional medication, 10 had serious intercurrent illness or surgery, 12 failed to attend and three withdrew consent. Placebo and active homeopathy had different effects on pain scores; mean pain scores were significantly lower after 3 months' placebo therapy than 3 months' active therapy (P=0.032 by Wilcoxon rank sum test). Articular index, ESR and morning stiffness were similar with active and placebo homeopathy. CONCLUSIONS: We found no evidence that active homeopathy improves the symptoms of RA, over 3 months, in patients attending a routine clinic who are stabilized on NSAIDs or DMARDs.     

Effect of age on 3 year outcome in early rheumatoid arthritis

OBJECTIVE: To investigate the effect of age on clinical and radiological outcome and on efficacy and tolerance of antirheumatic therapy in early rheumatoid arthritis (RA). METHODS: In a prospective 3 year study 113 patients (83 women, 30 men) were divided into 2 groups according to age at onset of disease: before (n = 55) and after 55 years of age (n = 58). For clinical outcome, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor, Ritchie index, and number of swollen joints were measured. Radiological progression was analyzed by Larsen score. The principles of the "sawtooth" strategy were applied in the treatment of all patients. RESULTS: At baseline, inflammatory activity (ESR, CRP) and the Larsen score for hands were significantly higher in patients with late onset RA (LORA) and they also developed more extraarticular symptoms compared to patients with early onset RA (EORA). However, no differences were found in Ritchie index, number of swollen joints, or CRP values between the groups. Also during the followup there was a trend toward increased inflammatory activity (ESR) among LORA patients. After the initiation of antirheumatic therapy a parallel improvement in clinical activity was observed in the 2 groups. The frequencies of remissions, side effects, and withdrawals due to drug inefficacy did not differ significantly between the 2 groups. The radiological progression was also comparable. CONCLUSION: The onset of RA was more active in patients with LORA. However, the clinical course and the radiological progression were parallel in LORA and EORA patients. The "sawtooth" therapy was equally tolerated in both patient groups.     

Combined suppressive drug treatment in severe refractory rheumatoid disease: an analysis of the relative effects of parenteral methylprednisolone, cyclophosphamide, and sodium aurothiomalate.

A trial was designed to assess the effects of intramuscular sodium aurothiomalate or intravenous cyclophosphamide, or both, in combination with intravenous 'pulse' methylprednisolone in severe intractable rheumatoid arthritis. Thirteen patients with severe, active rheumatoid arthritis, unresponsive to conventional therapeutic regimens showed improvement in synovitis after receiving a single intravenous bolus of methylprednisolone (15 mg/kg). Early morning stiffness and Ritchie articular index remained improved over pretreatment values after 12 weeks. There was an early fall in the erythrocyte sedimentation rate, which returned to baseline levels by four weeks. A concomitant intravenous pulse of cyclophosphamide (1 g/m2 body surface area) given to eight patients did not confer any additional benefit. Six patients received sodium aurothiomalate, up to 100 mg intramuscularly a week, and in these patients the early improvement in synovitis induced by methylprednisolone was maintained. Thus between 12 and 24 weeks the Ritchie articular index, visual analogue pain score, erythrocyte sedimentation rate, haemoglobin, and immunoglobin G were significantly better in the patients treated with gold and methylprednisolone than in those treated with methylprednisolone alone, irrespective of whether they had received cyclophosphamide. Methylprednisolone pulse therapy given at the start of gold treatment results in early improvement in synovitis, maintained until the usual delay in achieving a therapeutic effect from gold has elapsed.
