The EuroQol (EQ-5D) generic health index comprises a five-part questionnaire and a visual analogue self-rating scale. The questionnaire may be used as a health index to calculate a 'utility' value or as a health profile. The validity, reliability and responsiveness of EQ-5D were tested in 233 patients with rheumatoid arthritis stratified by functional class. EQ-5D demonstrated moderate to high correlations with measures of impairment and high correlations with disability measures. Stepwise regression models showed that EQ-5D utility values and visual analogue scores were explained best as a function of pain, disability, disease activity and mood (R2 approximately 70%), although other variables (side-effects, years of education) were required to explain the visual analogue scores. The EQ-5D health index and visual analogue scale are more responsive than any of the other measures, except pain and doctor-assessed disease activity. The reliability of the EQ-5D index and EQ-5D visual analogue scale is as good or better than that of all other instruments except the Health Assessment Questionnaire. Some patients with severe long-standing disease had health states which attracted utility values below zero, i.e. from a societal perspective they were regarded as being in states 'worse than death'. The practical and ethical implications of these utility valuations are discussed, and at present the utility values should be used and interpreted with caution. With this caveat, EQ-5D is simple to use, valid, responsive to change and sufficiently reliable for group comparisons. It is of potential use as an outcome measure in clinical trials, audit and health economic studies, but further work is required on its performance in other clinical contexts and on the interpretation of the utility values.

The SF12 is a reliable, valid and responsive measure of health status in the majority of RA patients, and meets standards required for comparing groups of patients. Its application in the most severely disabled subjects is uncertain.

The main aim of this pilot study was to test the 'construct' validity of Euroqol, a new generic health status instrument which consists of a questionnaire and visual analogue scale. Its ability to measure both current health status and change in health status was assessed in 55 patients with RA. The Euroqol questionnaire and visual analogue scales showed significant and clinically relevant correlations with other condition-specific instruments measuring loss of function, joint pain, joint tenderness and mood; change in these symptoms as measured by the condition-specific instruments was also predictive of change in Euroqol scores. Either component of the Euroqol instrument provide an index of current clinical status and these data provide preliminary evidence for the 'construct' validity of Euroqol in RA. Further work is needed to evaluate more fully the sensitivity of Euroqol to change over time.

Results. Sixty-four patients were eligible for entry and were switched from oral MTX to 15 mg/week IM MTX. At baseline, the mean ؎ SD DAS28 was 5.6 ؎ 0.88; after 6 weeks of IM MTX, the DAS28 had improved by a mean of 0.42 (95% confidence interval [95% CI] 0.15-0.69). At 6 weeks, 54 patients still had a DAS28 of >3.2 and were therefore eligible for randomization. By 22 weeks, 1 patient (3.7%) in each group achieved the primary outcome of a DAS28 <3.2 (95% CI for the difference between the groups ؊15% to ؉15%). Five patients (18.5%) in each group showed an improvement of >1.2 in the DAS28 (95% CI for the difference between the groups ؊18% to ؉18%). One patient (3.7%) in each group achieved an ACR20 response, but none achieved a good response as defined by the EULAR response criteria. One patient in each group had a serious adverse reaction; minor adverse reactions were more frequently reported in the dose escalation group.Conclusion. Switching from oral to parenteral MTX 15 mg/week results in a minor improvement in disease control. For patients with active RA receiving 15

SUMMARY The accumulation of chloroquine and hydroxychloroquine in unfractionated mononuclear cells and in purified monocytes, lymphocytes, and neutrophil polymorphonuclear leucocytes (PMN) was measured in vitro. Accumulation of both drugs in leucocytes was time and dose dependent. Cellular levels comparable to those found during antirheumatic therapy were achieved by preincubation for 60 minutes with up to 0 1 mM chloroquine or hydroxychloroquine.

Health related quality of life can be improved over 6 months by provision of a nurse led counselling service but the effects are not sustained for 12 months.

Objective: To test the clinical equivalence and resource consequences of day care with inpatient care for active rheumatoid arthritis.
