The separate impact of tight control schemes and disease activity on quality of life in patients with early rheumatoid arthritis: results from the CAMERA trials.

OBJECTIVES: To examine in patients with early rheumatoid arthritis (RA) whether quality of life (QoL), independently of disease activity, is affected by tight control treatment strategy schemes. METHODS: In the Computer Assisted Management in Early RA (CAMERA) trials, patients with early RA, disease duration <1 year, no prior use of DMARDs) had been randomised to a methotrexate (MTX)-based tight control strategy or usual care (CAMERA study) or to 10 mg/d prednisone or placebo both added from start to a MTX-based tight control strategy (CAMERA-II study). In either study, randomisation to the more intensive strategy resulted in lower disease activity. To assess QoL, the 'Influence of Rheumatic Diseases on General Health and Lifestyle' questionnaire (IRGL) was used. Baseline and 1- and/or 2-year measurements were analysed with regression analyses with the IRGL (sub)scales as outcome variables and treatment strategy and disease activity assessing 28 joints (DAS28) as independent variables, correcting for baseline values of each scale and possible confounders (gender, age, rheumatoid factor status). RESULTS: There was no clear association between either of the treatment strategies and QoL, but a decrease in DAS28 was associated with improvement in the majority of QoL (sub)scales. CONCLUSIONS: No independent effect of the specific tight control strategies schemes on QoL was found, while there was a clear disease activity related effect. Thus frequent outpatient visits or the inclusion of prednisone in a tight control strategy did not negatively influence QoL.

Lack of understanding in fibromyalgia and rheumatoid arthritis: the Illness Invalidation Inventory (3*I).

BACKGROUND: Patients with rheumatic diseases may face 'discounting' (denying and patronising) or 'lack of understanding' because of having symptoms without external clinical signs, but instruments to assess such invalidation experiences are lacking. OBJECTIVES: To develop and evaluate the Illness Invalidation Inventory (3*I), to compare invalidation experiences of two groups of patients who differ in visual signs and laboratory findings-rheumatoid arthritis (RA) and fibromyalgia-and to examine the association of invalidation with health status. METHODS: A questionnaire (eight items with respect to five sources: spouse, family, medical professionals, work environment and social services) was constructed. It was completed by 142 patients with RA and 167 patients with fibromyalgia. RESULTS: Principal axis factoring with oblimin rotation yielded two factors with high internal consistency (α>0.70): 'discounting' (five items) and 'lack of understanding' (three items). Patients with fibromyalgia experienced significantly more discounting and lack of understanding from their family, medical professionals, colleagues and social services than did patients with RA. Both patient groups experienced more invalidation from social services, colleagues and family than from medical professionals and spouses. More discounting and lack of understanding correlated with poorer mental well-being and social functioning in both patient groups. Discounting correlated with more physical disability and pain in patients with RA. CONCLUSIONS: The 3*I is a brief, reliable instrument for assessing patients' perceptions of invalidation from different sources, which differ between patient groups and are associated with health status. Future validation research should clarify the clinical impact of invalidation on treatment adherence and outcome.

Intensive treatment with methotrexate in early rheumatoid arthritis: aiming for remission. Computer Assisted Management in Early Rheumatoid Arthritis (CAMERA, an open-label strategy trial).

BACKGROUND: To investigate whether intensive treatment with methotrexate (MTX) according to a strict protocol and a computerised decision program is more beneficial compared to conventional treatment with MTX in early rheumatoid arthritis. METHODS: In a two-year multicentre open label strategy trial, 299 patients with early rheumatoid arthritis were randomly assigned to the intensive strategy group or the conventional strategy group. Patients in both groups received MTX, the aim of treatment being remission. Patients in the intensive treatment group came to the outpatient clinic once every month; adjustment of the MTX dosage was tailored to the individual patient on the basis of predefined response criteria, using a computerised decision program. Patients of the conventional strategy group came to the outpatient clinic once every three months; they were treated according to common practice. Cyclosporine was added if patients had an inadequate response to maximal tolerated MTX doses. RESULTS: Seventy six (50%) patients in the intensive strategy group achieved at least one period of remission during the two year trial, versus 55 patients (37%) in the conventional strategy group (p = 0.03). Areas under the curve for nearly all clinical variables were significantly lower-that is, there was a better clinical effect for the intensive treatment group compared with the conventional treatment group. CONCLUSION: The results of this study show that it is possible to substantially enhance the clinical efficacy early in the course of the disease by intensifying treatment with MTX, aiming for remission, tailored to the individual patient. Furthermore, participating rheumatologists indicated that the computerised decision program could be a helpful tool in their daily clinical practice.

Diagnosis, treatment and follow-up control in 124 patients with basal cell carcinoma of the maxillofacial region treated from 1992 to 1997.

AIM: The aim of this study was to analyze diagnostic and therapeutic procedures and the outcome of patients treated for the most common malignant tumor of the facial skin, basal cell carcinoma. PATIENTS AND METHODS: The files of patients with basal cell carcinoma (BCC) treated over a period of 6 years were evaluated. Emphasis was placed on the frequency of second interventions, local recurrences and histological subtyping of tumors. RESULTS: One-hundred and twenty-four patients were treated for 216 basal cell carcinomas (solitary: 67%, multiple: 33%). The tumors were predominantly located in the skin covering the middle third of the face. The tumors were 30 mm or less in diameter in 86%. Treatment was exclusively surgical. Histopathological subtyping revealed solid (83%), sclerodermiform (10%), metatypical (4%) and multicentric (3%) tumors. Resection of adjacent bone was mandatory in 12 patients and orbital exenteration in 2. Further local resections were necessary after thorough histological investigation in 71% of patients. Local recurrences occurred in 14 patients, predominantly within the first year after ablative surgery. Relative to the small number of sclerodermiform BCC, this subtype was the most frequent tumor that developed local recurrences. CONCLUSION: Basal cell carcinoma is a malignant tumor, slowly growing and often showing wide extension to macroscopically non-affected sites. Resection of tumors is delicate in the maxillofacial region due to the predilection for sites of origin adjacent to structures of eminent importance for facial appearance. The sclerodermiform subtype is prone to local recurrence and these patients should be followed up carefully.

A good response to early DMARD treatment of patients with rheumatoid arthritis in the first year predicts remission during follow up.

OBJECTIVE: To describe the frequency and duration of remission in the Utrecht rheumatoid arthritis cohort of patients followed since diagnosis, and the clinical and treatment characteristics of patients with remission v those without. METHODS: In 1990 the Utrecht rheumatoid arthritis cohort study group started a clinical trial in which patients with recent onset of rheumatoid arthritis (<1 year) were randomised into four treatment groups: hydroxychloroquine (n = 169); intramuscular gold (n = 163); methotrexate (n = 166); and pyramid (n = 64). After two years, rheumatologists were allowed to prescribe any disease modifying antirheumatic drug. Remission was defined as: duration of morning stiffness < or =15 min, mean VAS pain < or =10 mm, Thompson joint score < or =10, and ESR < or =30 mm/h during at least six months. Cox regression analysis was used to determine baseline clinical, demographic, and treatment predictors of remission. RESULTS: Mean follow up duration was 62 months. Thirty six per cent achieved at least one period of remission. Median duration between diagnosis and the first remission period was 15 months for the intramuscular gold group, 18 months for the methotrexate and hydroxychloroquine groups, and 24 months for the pyramid group (NS). Predictors of remission were early response to initial treatment, less pain, rheumatoid factor negativity, and lower joint score at baseline. CONCLUSIONS: After a mean follow up duration of 62 months, only 36% of the patients had fulfilled the remission criteria at least once. A good response to treatment during the first year seems to be independently associated with remission rather than initial treatment alone.

Working status among Dutch patients with rheumatoid arthritis: work disability and working conditions.

OBJECTIVES: To assess work disability and variables associated with work disability among Dutch patients with rheumatoid arthritis (RA). METHODS: A questionnaire on working status was filled out by 296 patients of working age. Employment and work disability rates adjusted for age and sex from the Dutch population were determined using indirect standardization. Cox proportional hazard analysis was used to assess baseline predictors of work disability in a subgroup of patients (n = 195). RESULTS: After a mean disease duration of 4.3 yr, patients had a 0.78 (95% CI 0.67-0.88) chance of being employed and a 2.14 (95% CI 1.75-2.54) risk of being work disabled when compared with the Dutch population. Functional disability and job type at the start of the disease were predictors of future work disability. In total, 48 (37%) currently employed patients had changed their working conditions, of which reduced working hours (46%), reduced pacing of work (42%) and help from colleagues (49%) were the most important alterations. Of the 60 work disabled patients without a paid job, only 11 patients (18%) would be willing to work again. CONCLUSION: This study shows that the adjusted employment rates were lower and that work disability rates were higher in patients with RA when compared with the general Dutch population. In addition, a substantial number of employed patients had to change their working conditions due to RA. Only a minority of work disabled RA patients was willing to return to the paid labour force.

The course of radiologic damage during the first six years of rheumatoid arthritis.

OBJECTIVE: To describe the radiologic course in a large cohort of patients with early rheumatoid arthritis (RA) and to analyze individual components of damage. METHODS: Five hundred two patients with recent-onset RA (disease duration <1 year) underwent annual radiologic assessment for a maximum of 6 years in this longitudinal prospective study. The study was designed to investigate the efficacy of 3 different therapeutic strategies. For the assessment of radiologic damage, radiographs of the hands and feet were scored according to the modified Sharp/van der Heijde method (SHS; range 0-448). A mean of 2.9 (range 1-7) radiographs was read per patient. RESULTS: Stable rates of progression of the SHS, erosion score, and narrowing score were found over the course of RA: the mean rates were 8.6, 5.4, and 3.2 modified Sharp units per year, respectively. The rate of progression of newly (not previously) damaged joints declined, and the rate of progression of already damaged joints (which became more damaged) increased during followup, leading to an equal contribution to progression of the SHS at 5 years. The joints of the feet, especially the fifth metatarsophalangeal joint, generally became eroded earlier and more of them became eroded compared with the joints of the hands. CONCLUSION: Radiologic damage progresses at a constant rate. In advanced disease, monitoring the progression of previously existing damage is as important as assessing new abnormalities in previously undamaged joints. Radiographs of the feet should be included in assessments of radiologic damage that are used in clinical intervention trials and daily practice.

Aggressive treatment in early rheumatoid arthritis: a randomised controlled trial. On behalf of the Rheumatic Research Foundation Utrecht, The Netherlands.

OBJECTIVES: To compare three therapeutic strategies using slow acting antirheumatic drugs (SAARDs) in early rheumatoid arthritis (RA), for their disease modifying properties, toxicity, and lag time until treatment effect. METHODS: Patients with recent onset RA from six hospitals were randomly assigned to immediate initiation of one of three treatment strategies: (I) a "mild SAARD with a long lag time" (hydroxychloroquine, if necessary replaced by auranofin); (II) a "potent SAARD with a long lag time" (intramuscular gold, if necessary replaced by D-penicillamine); (III) a "potent SAARD with a short lag time" (methotrexate, if necessary replaced by sulfasalazine). Comparisons included two years of follow up. RESULTS: All SAARD strategies reduced mean disease activity. A greater percentage of patients improved clinically with strategies II and III than with strategy I: percentages of patients improved on joint score with strategies II and III (79% and 82%, respectively), which was statistically different from strategy I (66%). The same was true for remission percentages: 31% and 24% v 16%, respectively). Longitudinal analysis showed significantly less disability with strategy III, and a lower erythrocyte sedimentation rate with strategy II than with strategy I. In addition, radiological damage after one and two years, was significantly lower in strategies II and III (at two years median scores were 11 and 10 v 14 in strategy I, p<0.05). Toxicity was increased in strategy II compared with the other strategies. CONCLUSION: Strategy III, comprising methotrexate or sulfasalazine, produced the best results weighing effectiveness and toxicity. Strategy I (hydroxychloroquine or auranofin) was slightly less effective, and strategy II (intramuscular gold or D-penicillamine) was associated with increased toxicity.

Toxicity of anti-rheumatic drugs in a randomized clinical trial of early rheumatoid arthritis.

OBJECTIVE: To evaluate the toxicity of slow-acting anti-rheumatic drugs (SAARDs) and non-steroidal anti-inflammatory drugs (NSAIDs) in early rheumatoid arthritis. METHODS: Patients were randomized to receive a SAARD-hydroxychloroquine (HCQ; n=120), i.m. gold (n=114) or methotrexate (MTX; n=118)-or a NSAID only (n=67). Patients in the three SAARD groups were allowed to take NSAIDs. Follow-up included 545 patient-years (p-yr). Adverse effects were attributed to specific medications using the Naranjo scoring method. RESULTS: Fifty-five per cent of the patients suffered from adverse effect(s). Adverse effects were most common during i.m. gold therapy (87 per 100 p-yr), which led to permanent discontinuation of this treatment in 31 cases. The incidences of adverse effects that were probably attributable to NSAIDs in patients treated simultaneously with a SAARD were similar for the three SAARD groups. The mean period until the first adverse effect was longer in the MTX group (39 weeks) than in the HCQ group (27 weeks). Baseline clinical and sociodemographic parameters were not predictive of the occurrence of adverse effects. CONCLUSION: No adverse effect could be classified as definitely related to either SAARDs or NSAIDs by the Naranjo scoring method. The incidence of possible adverse effects of NSAIDs and SAARDs was 72 per 100 p-yr, and adverse effects led to permanent discontinuation of the therapy in 56 cases (13%) (31 patients receiving i.m. gold, 12 receiving MTX, 10 receiving HCQ and three receiving NSAID only).

The effectiveness of early treatment with "second-line" antirheumatic drugs. A randomized, controlled trial.

OBJECTIVE: To compare two therapeutic strategies for patients with recent-onset rheumatoid arthritis. DESIGN: Open, randomized clinical trial. SETTING: Outpatient clinics of six clinical centers. PATIENTS: 238 consecutive patients with recently diagnosed rheumatoid arthritis. INTERVENTIONS: Delayed or immediate introduction of treatment with slow-acting antirheumatic drugs (SAARDs). MEASUREMENTS: Primary end points were functional disability, pain, joint score, and erythrocyte sedimentation rate at 6 and 12 months and progression of radiologic abnormalities at 12 months. RESULTS: Statistically significant advantages at 12 months for patients receiving the SAARD strategy (immediate treatment with SAARDs) with regard to all primary end points that may be clinically important are indicated by the differences in improvements from baseline and their 95% CIs. These differences were 0.3 (95% CI, 0.2 to 0.6) for disability (range, 0 to 3), 10 mm (CI, 1 to 19 mm) for pain (range, 0 to 100 mm), 39 (CI, 4 to 74) for joint score (range, 0 to 534), and 11 mm/h (CI, 3 to 19 mm/h) for erythrocyte sedimentation rate (range, 1 to 140 mm/h), all in favor of SAARD treatment. The SAARD strategy also appears to be advantageous at 6 months. Radiologic abnormalities progressed at an equal rate in the SAARD and the non-SAARD groups; the difference in progression (range, 0 to 448) was 1 (CI, -3 to 5). Analyses were based on the intention-to-treat principle and thus included 29% of patients in the non-SAARD group who discontinued the non-SAARD treatment strategy; treatment was usually discontinued because of insufficient effectiveness. The SAARD strategy including two alternative SAARDs could not be continued by 8% of patients, usually because of adverse reactions. CONCLUSIONS: Early introduction of SAARDs may be more beneficial than delayed introduction for patients with recently diagnosed rheumatoid arthritis.

Endpoint measures in rheumatoid arthritis clinical trials: group summary and individual patient analysis.

OBJECTIVE: To evaluate the responsiveness of measures of disability, discomfort, and disease process in rheumatoid arthritis (RA) clinical trials, when used as group summary variables and as variables of individual patient improvement. METHODS: Disease outcome and process measures were assessed in 97 patients with RA of recent onset, who were participating in a prospective trial comparing the effectiveness of several drug treatment strategies. Measurements were done after 3 and 6 months of treatment. Group summary analysis was performed with tests of statistical significance of changes, and by calculating effect sizes (i.e., mean change in an endpoint divided by its standard deviation). Individual patient improvement was defined as improvement of > or = 33% compared to baseline, according to recommendations of the recently held Conference on Outcome Measures in Rheumatoid Arthritis Clinical Trials. RESULTS: Almost all mean group changes in endpoints were statistically significant (p < 0.001). Effect sizes and figures on individual patient improvement provided additional information: physical discomfort measures were rapidly responding measures that did not further improve after 3 months; disease process measures, joint count, erythrocyte sedimentation rate and C-reactive protein also responded quickly and kept improving up to 6 months; the disability measures were relatively unchanged at 3 months, and only the self-report questionnaire score showed considerable improvement at 6 months. CONCLUSION: Effect sizes and data on patients who showed clinical improvement in disease process or outcome measures offset the strongly significant p values of statistical tests for almost all endpoint measures. Although discomfort measures rapidly responded to therapy, disability and disease process measures may not reach optimal improvement within 6 months.

Methylprednisolone pulse therapy in conjunction with azathioprine in rheumatoid arthritis.

In the management of rheumatoid arthritis two potentially useful roles for methylprednisolone (MP) pulse therapy are presently recognised: in patients in whom second line drugs have not led to a satisfactory remission or have caused side effects, and in bridging the gap between the start and the delayed onset of effect of a slow-acting antirheumatic drug. Recently it was shown that MP-pulse therapy was effective in accelerating the response to sulphasalazine and D-penicillamine. Nineteen patients with a persistently active rheumatoid arthritis, who had failed to respond to at least two slow-acting antirheumatic drugs, were treated with MP-pulse therapy in conjunction with azathioprine. Twelve patients continued this treatment for 6 months and 8 for 12 months. MP-pulse therapy resulted in an immediate improvement in Ritchie articular index, grip strength, ESR and CRP. However, this improvement lasted less than six weeks. After 6 months some improvement due to the effect of azathioprine became apparent. Some rather serious side effects were noted. It is concluded that MP-pulse therapy has a (short lasting) beneficial effect in persistently active rheumatoid arthritis. However MP-pulse therapy is not suitable to bridge the gap between the introduction of azathioprine-treatment and the delayed response to this drug.
