Abstract
Aims We aimed to assess the scale of the problem of illiteracy among our hospital's general medical in-patients and investigate any influence on literacy from gender, age, socioeconomic status, disease process and number of prescribed medications. Methods We employed a shortened version of the previously validated Rapid Estimate of Adult Literacy in Medicine (REALM) tool with medical inpatients at Glasgow Royal Infirmary. We also recorded gender, date of birth and clinical problem. Socioeconomic status was estimated from the patient's postcode using the Scottish Index of Multiple Deprivation (SIMD). Results 60 patients were invited to participate, however six (10%) declined. We therefore gathered data for 54 patients (54% male) with a mean age of 67 years. The female group had a significantly higher mean age of 73 years versus 62 years in men. The mean SIMD quintile was 3.5 (1 least deprived, 5 most deprived) and the mean number of medications was 7. 55% of our patients had a mean score of<60 which represents low health literacy. There were no significant differences in literacy between men (median score 59) and women (median score 60). Reading ability was not found to be associated with socioeconomic group, diseased body system or number of medications on the drug chart (data not shown). Conclusions Low level health literacy is prevalent. Affected individuals may have difficulty understanding patient-orientated health literature, medication instructions, clinic appointment cards and hospital signage.

Abstract
Rheumatoid Arthritis (RA) is a common inflammatory arthritis' with pain and loss of function among its most disabling symptoms. These are mostly secondary to inflammation or mechanical damage to the joints. However it is also important to consider disease complications as a cause of symptoms, especially when the response to treatment is suboptimal. We report an RA patient whose symptoms were resistant to standard therapy, and were actually due to peripheral neuropathy.

Abstract
BACKGROUND A Mediterranean-type diet rich in fish, fruit and vegetables and low in saturated fats has been associated with health benefits, including improved cardiovascular profile and benefit in RA. OBJECTIVE To overcome obstacles to healthy eating by a community-based intervention promoting a Mediterranean-type diet in patients with RA living in socially deprived areas of Glasgow. METHODS 130 female patients with RA aged 30-70 years (median 55), disease duration 8 years were recruited from three hospital sites. The intervention group (n = 75) attended weekly 2-hour sessions for 6 weeks in the local community, including hands-on cooking classes backed up with written information. The control group (n = 55) were given dietary written information only. Both groups completed food frequency questionnaires (FFQs), and clinical and laboratory measures were assessed at baseline, 3 and 6 months. RESULTS Significant benefit was shown in the intervention group compared with controls for patient global assessment at 6 months (p = 0.002), pain score at 3 and 6 months (p = 0.011 and 0.049), early morning stiffness at 6 months (p = 0.041) and Health Assessment Questionnaire score at 3 months (p = 0.03). Analysis of the FFQs showed significant increases in weekly total fruit, vegetable and legume consumption and improvement in the ratio of monounsaturated:saturated fat intake and systolic BP in the intervention group only. The cooking classes were positively received by patients and tutors; cost/patient for the 6 week course was 84 pounds (124 euro). CONCLUSIONS Results demonstrate that a 6 week intervention can improve consumption of healthier foods. If implemented more widely it may prove a popular, inexpensive and useful adjunct to other RA treatment.

Abstract
BACKGROUND Evidence for disease modifying activity of low dose corticosteroid treatment in rheumatoid arthritis is contradictory. Studies showing radiological benefit suggest that continued treatment is required to sustain the effect. OBJECTIVE To evaluate the effect of low dose oral prednisolone in early rheumatoid arthritis on disease activity over two years. DESIGN Double blind placebo controlled trial. METHODS Patients with rheumatoid arthritis, duration <3 years (n = 167), were started on a disease modifying antirheumatic drug (DMARD; sulphasalazine) and allocated by stratified randomisation to prednisolone 7 mg/day or placebo. Primary outcome measure was radiological damage, assessed by the modified Sharp method. Clinical benefit was a secondary outcome. A proactive approach to identifying and treating corticosteroid adverse events was adopted. Patients who discontinued sulphasalazine were offered an alternative DMARD. RESULTS 90 of 257 patients eligible for the study refused to participate (more women than men). Of those enrolled, 84% were seropositive for rheumatoid factor, median age 56 years, median disease duration 12 months, female to male ratio 1.8:1. Prednisolone was given to 84 patients; of these 73% continued prednisolone and 70% sulphasalazine at 2 years. Of the 83 patients on placebo, 80% continued placebo and 64% sulphasalazine at 2 years. There were no significant differences in radiological score or clinical and laboratory measures at 0 and 2 years. CONCLUSIONS Low dose prednisolone conferred no radiological or clinical benefit on patients maintained on a DMARD over two years. Low dose corticosteroids have no role in the routine management of rheumatoid arthritis treated with conventional disease modifying drugs.

Abstract
OBJECTIVE To assess the attitudes of rheumatoid arthritis (RA) patients to oral corticosteroid treatment, factors influencing these views and their likely clinical impact. METHODS A cross-sectional survey of 158 consecutive RA out-patients was carried out at two centres over 2 weeks. Demography, disease duration, function [Health Assessment Questionnaire (HAQ)], erythrocyte sedimentation rate (ESR), years of formal education and social deprivation index were noted. Prospective recruitment into the multicentre West of Scotland Early Rheumatoid Arthritis Corticosteroid Trial (WOSERACT) was monitored and reasons for refusal to participate (when available) were noted at three of the centres. RESULTS Forty-eight (32%) patients were willing to be treated with oral corticosteroid and 100 (68%) were not. The former were older (P = 0.002), had a higher ESR (P = 0.007), poorer function (P = 0.001) and greater previous exposure to disease-modifying anti-rheumatic drugs (P = 0.013). Ninety patients refused to participate in WOSERACT, in 46 cases (40 female, 6 male) the reason being concerns about corticosteroids. CONCLUSIONS This study shows a high level of concern about and refusal of corticosteroid treatment in RA, due mainly to patient concerns about adverse effects. Rheumatologists need to be aware of these attitudes as they are likely to affect prescribing.

Abstract
For the many patients who suffer chronic pain, we seek the most effective anti-inflammatory drug with the least side-effect profile and the greatest long-term safety. Etoricoxib, a selective COX2 inhibitor, has been shown to be as effective as non-selective non-steroidal anti-inflammatory drugs in the management of chronic pain in rheumatoid arthritis and osteoarthritis, for periods of up to one year. Data on etoricoxib efficacy in chronic low back pain is beginning to emerge. The side-effect profile of etoricoxib suggests it is well tolerated with similar adverse effects to non-selective NSAIDs. Larger studies are awaited, to see whether superior gastrointestinal tolerability can be proven. Further work will be required to show that etoricoxib is safe in patients with pre-existing cardiovascular or gastrointestinal comorbidity, and the potentially confounding role of aspirin still needs to be elucidated. However, etoricoxib shows promise as a new and effective COX2 inhibitor in clinical practice.

Abstract
OBJECTIVES To determine the proportion of patients attending a rheumatology clinic who have access to a computer with Internet capabilities, to establish how often they search for health information, and how difficult or useful they find this resource. METHODS We performed a questionnaire-based study of consecutive patients attending a rheumatology clinic in two city teaching hospitals over a 1 week period. Patients were asked if they owned or had access to a computer with Internet capabilities, and if they had searched for information on shopping, holidays, entertainment or health information. Further questions were then directed at the nature of the health information, how useful it was and how easy the patient found it to access the details. Patient demographic data were obtained by case record review. RESULTS One hundred and forty patients were approached; 138 completed questionnaires were collected. One hundred and one respondents (73%) were female. Median patient age was 58 yr (range 18-84). One hundred and seven (78%) had rheumatoid arthritis, with median disease duration of 8 yr (range 6 months to 49 yr). Sixty (43%) had access to the Internet, mostly at home, and used it most frequently for holiday information. Thirty-seven (27% of all respondents) reported that they had searched for medical information on a median of 2 (range 1-10) occasions in the previous 12 months. Of these, 83% perceived the information as useful, 54% discovered something they had not previously known and 31% reported it was easier than asking their doctor or nurse. Patients searched on-line for information on their arthritis (83%), drug treatment (54%), alternative therapies (31%), diet and arthritis (46%) and patient organizations (11%). No patients recalled being advised to search for information by their doctor or nurse. Patients who searched for medical information were younger (median age 48 vs 62 yr; P<0.001), more likely to be employed (32 vs 16%) and more likely to be married or in a stable relationship (84 vs 66%); there were no differences in sex distribution, diagnosis, disease duration or social deprivation. CONCLUSIONS One in four patients attending our rheumatology clinic had searched the Internet for medical information in the last 12 months. Almost one-third found it easier than asking their health-care professional. Further studies are required to explore the wider application of this resource and to determine the validity and reliability of the information obtained.

Abstract
OBJECTIVES To determine the prevalence of illiteracy in a cohort of rheumatoid arthritis (RA) patients and the impact of illiteracy on disease severity and function. METHODS We performed a prospective cross-sectional study with case record review of 127 consecutive patients with RA attending one centre. All patients completed the Rapid Estimate of Adult Literacy in Medicine (REALM) screening test. This 66-word recognition test provides an estimate of reading level in less than 3 min. Demographic data were collected by interview and case record review. Function was assessed with the Health Assessment Questionnaire (HAQ) and depression with the Hospital Anxiety and Depression (HAD) scale, both sent prior to clinic attendance. Social deprivation was assessed with the Carstairs index. RESULTS Four patients refused to participate. Of these, three stated they were unable to read. Ninety-seven women and 26 men agreed to be interviewed. All but two were Caucasian. Median age was 56 yr (range 19-77 yr) and median disease duration was 10 yr (range 1-60 yr). Median number of previous disease-modifying anti-rheumatic drugs (DMARDs) was two. Eighteen (15%) patients were functionally illiterate, with a REALM score of less than 60. Sex, age, disease duration and numbers of joint replacements and previous DMARDs were not influenced by illiteracy. Illiteracy led to more anxiety (P=0.011), but did not affect HAQ score (P>0.5). Illiteracy was more common in the deprived (P=0.0064). Illiterate patients had three times more hospital visits compared with age- and sex-matched RA controls over the previous 12 months. CONCLUSIONS One in six of our patient population are illiterate and would struggle to cope with patient education materials and prescription labels. These patients had significantly more hospital visits but equal function, suggesting that additional resources be directed towards these individuals. The REALM test is quick and easy to administer and allows us to identify patients who may require more appropriate literature.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is associated with significant excess morbidity and mortality. Cardiovascular disease is the commonest cause of premature death in patients with RA. In recognition of this, blood pressure, weight, and smoking history are routinely ascertained in the clinic and appropriate advice and treatment started. AIMS To ascertain if attending a specialist nurse, in addition to routine medical care, would increase the success in dealing with lifestyle variables in a cohort of patients with RA. METHODS Twenty two consecutive patients starting treatment with the disease modifying antirheumatic drug (DMARD) sulfasalazine were invited to attend an additional clinic dealing with lifestyle factors every 12 weeks over a 48 week follow up. Smoking and alcohol history, baseline demographic and metrology assessments were determined for all patients. Body mass index (BMI) was calculated, blood pressure recorded, function assessed by the Health Assessment Questionnaire (HAQ), and social deprivation determined by the Carstairs Index. Patients were advised on exercise and diet, and serum cholesterol was measured. RESULTS Twenty women and two men, with a mean age of 52 years and mean disease duration of five years, were enrolled. Eight patients smoked and, unfortunately, none were persuaded to discontinue. Fifteen of the cohort were already taking regular exercise; one additional patient began swimming regularly. At baseline, 10 patients were found to have a high cholesterol, with a mean of 6.8 mmol/l. A 14% reduction in mean cholesterol was achieved by dietary modification, and three patients merited statin treatment. Obesity is a major problem in our population and 15 of the patients had grade I obesity with a mean BMI of 30.6; five of these gained a further 4.5 kg. Six patients with previously untreated hypertension were identified, but unfortunately five remained hypertensive and only two had received anti-hypertensive drugs. CONCLUSIONS Educating patients in order to change lifestyle habits and influence outcome is a long term challenge facing all healthcare workers. In our cohort, most adverse lifestyle factors had already been recognised and discussed by the general practitioner or at prior clinic visits. Additional advice and input led to only modest improvement.

Abstract
OBJECTIVE To identify the features of rheumatoid cervical spine disease associated with deterioration resulting in the need for surgical intervention or death. PATIENTS AND METHODS Patients with rheumatoid cervical myelopathy who underwent cervical spine magnetic resonance imaging (MRI) between 1991 and 1996 were identified. Patients requiring immediate surgical intervention were excluded. The remainder were divided into two groups. Deterioration group: patients requiring surgical intervention during the follow-up period and deaths resulting from cervical myelopathy. Conservative group: all other patients. Relevant clinical features and radiology reports were extracted retrospectively from the casesheet. RESULTS The deterioration group comprised 11 patients (12%), median time to deterioration 15 months (range 4-84 months). The conservative group included 82 patients. Initial clinical features did not differ significantly between the two groups. Sixty per cent of those patients with compression or impingement at the atlanto-axial level on first MRI deteriorated over a median of 12 months (range 4-36 months). CONCLUSION Deterioration is likely if there is evidence of cord compromise at the atlanto-axial level on MRI regardless of initial clinical and plain X-ray features.

Abstract
OBJECTIVE To compare the risk-benefit ratio of intramuscular gold (gold sodium thiomalate (GST)) and methotrexate (MTX) in a population with rheumatoid arthritis (RA) from a deprived area. METHODS Patients with active RA were randomly assigned to open treatment with GST or MTX. Clinical and laboratory assessment was performed at 0, 12, 24, and 48 weeks. Results were analysed on an intention to treat basis. RESULTS 141 patients were recruited-72 were randomly allocated to GST and 69 to MTX. There were no statistically significant differences found in either the clinical or demographic variables at baseline. At 48 weeks 31 (43%) patients continued to receive GST and 43 (62%) MTX. The median MTX dose achieved was 10 mg. Gold caused significantly more withdrawals for toxicity (43% GST v 19% MTX, p=0.0026, log rank test). Both groups experienced a significant improvement in erythrocyte sedimentation rate, C reactive protein, Ritchie Articular Index, and pain score by 24 weeks (p<0.001, Friedman test). Although a trend towards an improved Health Assessment Questionnaire (HAQ) score and global wellbeing was seen in both groups, this did not reach statistical significance. No differences in efficacy were found when the two groups were compared (Mann-Whitney). CONCLUSION GST and low dose MTX showed equivalent efficacy, but toxicity was more common in patients treated with GST. GST, although more toxic, remains a useful alternative for patients in whom MTX is contraindicated.

Abstract
The trend for more aggressive management of rheumatoid arthritis includes earlier introduction of disease modifying antirheumatic drugs (DMARD). As patients may continue their therapy for several decades instead of several years, the evaluation of benefit versus risk of DMARD with particular emphasis on longterm safety is essential. Longterm safety assessment is difficult for a number of reasons: there are relatively few trials that have followed patients beyond 5 years and the use of a combination of DMARD therapy with nonsteroidal antiinflammatory drugs and corticosteroids complicates the assessment of an observed adverse event with a particular drug. This review of longterm studies incorporating DMARD provides insight into adverse events associated with currently available DMARD.

Abstract
OBJECTIVE To compare prevalent cardiovascular disease, conventional cardiovascular risk factors and thrombotic variables in a cohort with well-controlled rheumatoid arthritis (RA) and in population controls. METHODS Seventy-six RA patients and 641 controls, randomly sampled from the local population in the North Glasgow MONICA study. Conventional cardiovascular risk factors (blood pressure, smoking, cholesterol) and thrombotic variables [fibrinogen, von Willebrand factor (vWF), tissue plasminogen activator antigen (t-PA), fibrin D-dimer, plasminogen activator inhibitor (PAI-1), plasma viscosity] were measured by standard procedures. RESULTS RA patients had a significantly higher prevalence of angina pectoris (P=0.03). Stroke also tended to be more common in the RA group, but the difference did not reach statistical significance (P=0.08). Diastolic blood pressure was significantly higher and serum cholesterol significantly lower in the RA group than in controls. Current smoking habits and exercise history were similar in the two groups, although RA patients were more likely to have previously smoked. Significant elevations in several thrombotic predictors of cardiovascular disease (fibrinogen, vWF, t-PA antigen and fibrin D-dimer) were found in the RA group. CONCLUSIONS In this RA patient population, diastolic blood pressure was higher than in controls and thrombotic variables were elevated compared with controls. These features are identified as potential additional cardiovascular risk factors in the RA patients studied. Prospective studies of risk modification may permit the identification of factors which could lead to a reduction in the known increased cardiovascular risk in RA.

Abstract
Functional status in rheumatoid arthritis (RA) as assessed by the HAQ is poorer in the West of Scotland than the USA or elsewhere. There is a possible link with social deprivation, which is common within the Greater Glasgow Healthboard area. Our aim was to determine if differences in lifestyle could contribute to the poorer functional outcome found in socially deprived patients.

Abstract
OBJECTIVES To determine the influence of interleukin 1alpha (IL1alpha), IL1beta, and IL1 receptor antagonist gene polymorphisms on disease outcome as assessed by the need for major joint surgery within 15 years of diagnosis. PATIENTS AND METHODS 50 patients with rheumatoid arthritis (RA) who required major joint surgery (hip, knee, or shoulder arthroplasty) within a 15 year period of disease diagnosis and 50 patients with RA with disease duration greater than 15 years and no major surgery were recruited together with 66 normal west of Scotland controls. Genomic DNA and polymerase chain reaction were used to determine polymorphisms in the genes for IL1alpha, IL1beta, and IL1 receptor antagonist. For all patients with RA recruited to the study, HLA-DR beta1 gene status was recorded as was the erythrocyte sedimentation rate (ESR) at the first ever clinic visit. RESULTS No difference in the allele frequencies or genotypes of the IL1alpha and IL1 receptor antagonist gene polymorphisms was found between the controls and patients with RA, with or without previous surgery. IL1beta allele 2 was overrepresented in patients with RA who had undergone surgery compared with patients who had not (40% v 27%, chi(2)=4, 1df, p=0.04). ESR at the first ever clinic visit was significantly higher in those carrying allele 2 (36 mm/1st h v 22 mm/1st h, p=0.04). When patients, with or without previous surgery, who did not carry two disease associated HLA-DR beta1 alleles were compared, an increase in allele 2 was observed in the surgery cohort (42% v 25%, chi(2)=4.8, 1df, p=0.03). CONCLUSIONS Patients who require major joint surgery were found to carry the IL1beta allele 2 more often than expected. Patients with this allele also had a higher initial ESR. This may be useful in predicting early surgery in patients who do not carry two disease associated HLA-DR beta1 alleles. Although these findings are interesting, further functional and epidemiological studies to confirm these observations are required.

Abstract
OBJECTIVES (1) To compare clinical outcome and symptomatology of rheumatoid cervical myelopathy between patients managed conservatively and surgically. (2) To determine if surgical outcome has improved since the series published from this unit in 1987. (3) To examine the role of magnetic resonance imaging (MRI) in the diagnosis of cervical myelopathy. METHODS Patients undergoing MRI of the cervical spine between 1991 and 1996 were identified. Case records were reviewed retrospectively. RESULTS 111 patients with RA underwent 124 MRI scans. The median age at onset of cervical spine symptoms was 58 years (range 16-87) with median disease duration of 16 years (range 1-59). 18 (16%) required surgery immediately after MRI. 93 (84%) were managed conservatively, 9 of whom (10%) later required surgery. 2/7 deaths in the conservative group were directly related to cervical myelopathy. Patients requiring surgery were more likely to report paraesthesia, weakness, unsteadiness and to exhibit extensor plantar reflexes, gait disturbance, and reduced power. MRI findings did not correlate with clinical features. When compared with the 1974-82 cohort, fewer patients had severe myelopathy (Ranawat grade IIIB) before surgery (34% versus 7%). Early postoperative mortality improved from 9% to 0% and surgical complication rate fell from 50% to 22%. 89% of patients in the 1991-96 cohort reported subjective improvement in overall function. CONCLUSION In this series surgical outcome has improved. The major factor in this more favourable outcome is probably that patients presenting with rheumatoid cervical myelopathy are now referred for surgery at an earlier stage of disease. Clinical findings correlate poorly with MRI findings, therefore clinical history should remain the key to determining the need for MRI.

Abstract
BACKGROUND Socioeconomic deprivation is associated with increased mortality from cardiovascular causes and malignancy. The influence of disadvantage in patients with rheumatoid arthritis (RA), who are known to have premature mortality, has not been ascertained. AIM To assess the relation between the level of patient deprivation and mortality in RA patients. METHODS 200 RA patients, enrolled in a study comparing sulfasalazine and penicillamine in 1984-85, have been followed up prospectively for 12 years. Subjects were categorised into Carstairs groups with deprivation scores ranging from 1 (most affluent) to 7 (most deprived). Information about deaths was obtained from the Registrar General in Scotland, death certificates and GP/hospital records. RESULTS There were more RA patients in the deprived areas then expected compared with the West of Scotland and England and Wales. Some 47.5% of the RA patients had died by 12 years-the majority of cardiorespiratory causes or malignancy. There were no differences in the median age or disease duration in the various Carstairs groups at study entry, but the percentage of deaths was higher in the more deprived groups after 12 years (36% dead in most affluent area compared with 61% in the most deprived, that is, in groups 6 and 7). CONCLUSION In patients with RA increasing deprivation was associated with premature mortality. If confirmed elsewhere these findings have implications for rheumatological management strategies, for researchers involved in collaborative studies of patients from different socioeconomic backgrounds and for resource allocation.

Abstract
BACKGROUND Sulphasalazine (SSZ) has been reported to cause drug induced systemic lupus erythematosus (SLE), but diagnosis of this complication in the context of rheumatoid arthritis (RA) is difficult. OBJECTIVE To determine prospectively: (1) if patients become seropositive for antinuclear antibodies (ANA) during prolonged treatment with SSZ without clinical evidence of SLE; (2) if ANA positive patients develop more adverse reactions than ANA negative patients; (3) if drug induced SLE was identified in this cohort. METHODS 200 patients enrolled in a randomised prospective trial of SSZ and auranofin (AUR) were followed up for five years. Baseline and annual ANA results were collected along with information on drug toxicity and reasons for discontinuation of treatment. RESULTS Over five years 24 patients stopped taking SSZ and 49 AUR because of side effects. Of the features common to SLE, rash developed in nine SSZ patients and 11 AUR treated patients and mouth ulcers in three and four patients respectively. Six SSZ treated patients and three treated with AUR developed leucopenia, which promptly resolved with drug withdrawal. No adverse event was ascribed to drug induced SLE. Of the 72 SSZ treated patients who were ANA negative or weakly positive at outset, 14 (19%) became strongly ANA positive compared with 11 (14%) of 80 AUR patients. Patients ANA positive at baseline or who became ANA positive were not more likely to develop drug toxicity or to withdraw from treatment than those ANA negative throughout. CONCLUSION ANA positivity is common in patients with RA, but the presence or development of ANA did not increase the likelihood of withdrawing from treatment. No case of drug induced SLE was seen over five years in this study.

Abstract
OBJECTIVE To determine the value of HLA DR beta 1 disease associated epitope (DAE) and erythrocyte sedimentation (ESR) in predicting the need for major joint replacement in rheumatoid arthritis (RA). METHODS Sixty five RA patients who had undergone hip, knee or shoulder arthroplasty within 15 years of disease onset and 65 who had not. HLA DR beta 1 genotype was determined by polymerase chain reaction. ESR at first hospital visit was noted. RESULTS Significantly more patients with two DAE required surgery, (32% v 9%), chi 2 = 13.9, p = 0.001, odds ratio = 5.4 (95% CI: 1.8, 16). Sensitivity was poor, 32%, specificity high, 91%. Presentation ESR was higher in surgery patients compared with non-surgery patients, 52 mm 1st h v 25 mm 1st h, p < 0.001, but was independent of DAE status. Sensitivity of an ESR of 30 mm 1st h was 75%, specificity 53%. CONCLUSION The presence of two DAE is a risk factor for major joint surgery in RA and is independent of ESR, whereas in those with one or no DAE, a high ESR is an important predictor.

Abstract
BACKGROUND Substantial hematologic toxicity limits the use of azathioprine. OBJECTIVE To evaluate 1) polymorphic inactivation of azathioprine by thiopurine methyltransferase and 2) clinical toxicity. DESIGN Prospective cohort study. SETTING Two rheumatology units. PATIENTS 67 patients for whom azathioprine was prescribed as second-line therapy for rheumatic disease. MEASUREMENTS Polymerase chain reaction-based assays were used to detect mutations in thiopurine methyltransferase. The primary end point was discontinuation of azathioprine therapy because of toxicity. RESULTS Six of 67 patients (9%) were heterozygous for mutant thiopurine methyltransferase alleles. Five of the 6 patients discontinued therapy within 1 month of starting treatment because of low leukocyte counts. The sixth patient did not adhere to treatment. Patients with wild-type thiopurine methyltransferase alleles received therapy longer than did patients with mutant alleles (median duration of therapy, 39 weeks [range, 6 to 180 weeks] and 2 weeks [range, 2 to 4 weeks], respectively; P = 0.018). CONCLUSION Analysis of thiopurine methyltransferase genotype is a quick way to identify patients at risk for acute toxicity from azathioprine.

Abstract
OBJECTIVE To assess existing disease modifying antirheumatic drugs (DMARD) using a strategy aiming for sustained suppression of inflammation. METHODS We conducted intention-to-treat analysis of open randomized study [sulfasalazine (SASP) or penicillamine (PEN)], followup 12 years, conducted at specialist rheumatology clinics in Glasgow, Scotland. Subjects were 200 patients with rheumatoid arthritis (RA) with established disease. In this "true to life" approach, comorbidity was not an exclusion criterion unless it prejudiced assessment of drug toxicity. The main outcome measure was the Health Assessment Questionnaire (HAQ) functional score. RESULTS Over 12 year followup 95 (47.5%) patients died; this was the commonest reason for study groups being unfulfilled. There was one drug related death (methotrexate). Patients who were socially disadvantaged were more likely to die prematurely. HAQ did not deteriorate significantly in those who continued taking their original DMARD, or in the SASP intention-to-treat group over 12 years. Sustained suppression of disease activity was possible in the entire group available for followup at 12 years. Most toxicity occurred early and no unexpected side effects were observed. CONCLUSION High premature mortality in RA was confirmed and an association between mortality and deprivation was demonstrated. Sustained reduction in acute phase response was possible using sequential single DMARD. This study provides useful baseline and longterm information against which to evaluate combination therapy or new agents.

Abstract
OBJECTIVE Social deprivation is now recognised to have an important impact on morbidity and mortality. This study sought to ascertain the effect of deprivation, if any, on disease severity, functional disability, and outcome in rheumatoid patients in Glasgow. METHODS 814 patients with rheumatoid arthritis (RA) were assessed for clinical, functional, and laboratory indices of disease activity. Deprivation categories for individual patients were determined using the Carstairs index. Five year follow up is available for 440 patients. RESULTS The study population of RA patients live largely in the most deprived areas. Patients from deprived areas have significantly poorer function at outset and at five years as defined by the Health Assessment Questionnaire (HAQ) score. This is not attributable to differences in disease duration in patients from the most deprived regions or compliance with treatment. Furthermore, these patients do not achieve over five years the initial functional level of those living in the most advantaged localities. CONCLUSION RA patients from deprived areas have poorer function, which is associated with greater need--medical, social, and paramedical. Strategies and resources for healthcare need to be adjusted according to this variation.

Abstract
OBJECTIVE To determine the effect of intramuscular gold and oral hydroxychloroquine (HCQ) on the lipid profile of patients with rheumatoid arthritis (RA). METHOD A prospective randomised clinical trial of 12 months' duration was performed in 100 RA patients. Data on clinical and laboratory parameters of disease activity, and fasting serum lipid samples was collected at baseline and at three monthly intervals over one year. RESULTS The expected second line response was seen with no significant difference in efficacy between the groups at 12 months. The HCQ group had a significant overall improvement in their lipid profile while there was a trend for lipid profiles in the gold group to worsen. CONCLUSIONS HCQ is an effective second line agent that has beneficial effects on serum lipids. This should be taken into account when choosing a disease modifying anti-rheumatic drug in patients who suffer from RA and who have significant cardiovascular risk factors.

Abstract
The aim of the study was to see whether rheumatoid arthritis (RA) is becoming a milder disease. Information on the initial disease activity and patient function (modified Health Assessment Questionnaire-HAQ) was collected in all RA patients enrolled into studies of sulphasalazine since 1980 in two Glasgow teaching hospitals. Patients (352) were enrolled in trials in the decade 1980-1989, and were compared to 374 patients enrolled in 1990-1994. Patients recruited in the 1980s were significantly younger, but had a similar disease duration to the 1990s patients. The 1980s patients had more active disease as measured by erythrocyte sedimentation rate (61 vs 44, P < 0.0001) and C-reactive protein (40 vs 26, P < 0.0001), and significantly worse function (HAQ 2.3 vs 1.9, P < 0.001). The response to sulphasalazine was very similar in the two cohorts, in terms of the percentage of patients remaining on therapy for 6 months, and the percentage improvement in measures of disease activity. Patients with milder disease were enrolled into the more recent trials of sulphasalazine. This may be because RA is becoming a milder disease, but other possible explanations are discussed.

Abstract
OBJECTIVE To compare results of medium to longterm sulfasalazine and auranofin treatment in active rheumatoid arthritis (RA). METHODS 200 patients with active RA were enrolled in a prospective, randomized trial comparing sulfasalazine (target dosage, 40 mg/kg/day) with auranofin (6-9 mg/day). Patients were assessed annually for 5 years, using clinical and laboratory measures of disease activity. Risk of discontinuing treatment was compared using life table analysis. RESULTS 31% of patients continued sulfasalazine for at least 5 years, compared to only 15% continuing auranofin (p < 0.05). Patients previously given intramuscular (i.m.) gold did particularly badly during auranofin treatment (only 1/26 continued therapy for 5 years), but after excluding all patients previously treated with i.m. gold from both groups more patients continued sulfasalazine for > 5 years (p < 0.05). Patients continuing therapy at 5 years had significantly milder disease at enrollment than those who did not. The patients continuing auranofin treatment at 5 years were no better than at the outset of the trial, and may represent a subgroup of patients with a good prognosis. Patients continuing sulfasalazine, however, showed sustained response over the 5 year period. CONCLUSION Sulfasalazine therapy was more likely to be continued for 5 years, suggesting better tolerability and/or efficacy than auranofin, and produced evidence of continuing benefit. Patients previously withdrawn from i.m. gold therapy because of inefficacy or minor toxicity should not be given auranofin therapy.

Abstract
Cervical myelopathy is a recognized complication of rheumatoid arthritis and other inflammatory arthropathies. In a significant proportion of patients, surgical stabilization of the cervical spine offers the best opportunity for improvement of symptoms and long-term survival. We report two cases that illustrate some potential complications of cervical spine surgery and which also emphasize the need for vigilance when caring for patients in this group.

Abstract
Antimalarial drugs are effective disease modifying agents in RA with a low incidence of serious toxic effects. Recently, combinations of second-line agents have been used in RA in attempts to treat patients with no response to a number of single agents, or suboptimal response to a single agent. Combinations of drugs have been selected for maximum efficacy and minimum toxicity, but clinical trials are difficult to design and interpret. In particular, ensuring adequate power to detect small differences in response poses a major problem. Antimalarials are an attractive choice for combination therapy due to their efficacy, mechanisms of action and toxicity profile. In this review, the evidence for the use of antimalarials in combination in RA is examined. No advantage has been shown in combining antimalarials with gold, penicillamine or sulphasalazine compared with monotherapeutic regimens. There is some evidence to suggest a beneficial combination of antimalarials with methotrexate, but this is as yet inconclusive. Open non-randomised uncontrolled studies have shown that antimalarials combined with cytotoxic agents are effective but highly toxic. The authors conclude that there is little good evidence to support the introduction of combination second-line drug therapy for RA into widespread therapeutic use.

Abstract
OBJECTIVE To examine the proposal that pretreatment low dose desensitisation may reduce the incidence of toxicity of sulphasalazine in the treatment of rheumatoid arthritis (RA). METHODS A double blind, placebo controlled trial was performed with 422 patients satisfying the American College of Rheumatology criteria for RA who required sulphasalazine treatment because of increased disease activity. Patients received either sulphasalazine desensitisation, or placebo, for three weeks before commencement of sulphasalazine treatment. The frequency and nature of adverse effects and changes in clinical and laboratory parameters of disease activity were measured after three and six months. RESULTS Improvement in the efficacy of sulphalasazine (measured by clinical and laboratory parameters) was significant and similar in magnitude in both groups. There was no significant difference between actively and placebo desensitised patients as regards the incidence or profile of adverse effects (toxicity). CONCLUSION Pretreatment low dose desensitisation is unhelpful in reducing the toxicity associated with sulphasalazine treatment of RA.

Abstract
This review of the use of sulphasalazine (SASP) in the therapy of rheumatoid arthritis refers to the placebo-controlled trials of SASP and the randomized comparative studies with other second-line drugs that have been published over the past decade. The questions relating to appropriate selection of patients for this treatment and the possible relevance of drug interactions are addressed. The favourable effect of SASP on functional, radiological and extra-articular outcome measures is highlighted, as is the reproducibility of published studies. Finally, the results from combination studies and meta-analyses are outlined.

Abstract
OBJECTIVE To compare the efficacy, tolerance and safety of 50-150 micrograms orally administered iloprost given twice a day versus placebo in patients with Raynaud's syndrome. METHODS The study was multicentre (n = 3), double blind and placebo controlled. Sixty three patients who had eight or more vasospastic attacks per week were enrolled. After a one week run-in period, all patients received either iloprost or placebo treatment to a maximum tolerated dose of 150 micrograms twice a day for 10 days. Diary cards assessed the duration and severity of the vasospastic attacks. Side effects were monitored by direct questioning. A global assessment of treatment efficacy was made by the patient at the end of treatment and two weeks later. RESULTS Patient opinion tended to favour iloprost at the end of the 10 day treatment phase (p = 0.09) and this was significant at day 24 (the follow up visit) (p = 0.011). Although the duration and severity of attacks tended to decrease in the iloprost treated group, these results tended not to reach statistical significance (for severity p = 0.06 at end of treatment, p = 0.09 on day 24). CONCLUSION Iloprost administered intravenously has been shown to be of benefit in the treatment of the Raynaud's syndrome associated with systemic sclerosis, but this route of administration is inconvenient. This study evaluated the use of iloprost administered orally to patients with Raynaud's syndrome. Patient documented improvement was significantly improved by iloprost. Diary card analysis showed a trend in favour of iloprost, but these results did not reach statistical significance.

Abstract
OBJECTIVE To investigate the effect of oral methotrexate (MTX) on circulating levels of interleukin 6 (IL-6) and soluble IL-2 receptor (sIL-2R) in patients with rheumatoid arthritis (RA). METHODS We measured serum concentrations of IL-6 (n = 20) and sIL-2R (n = 16) before MTX therapy and again after 12 weeks. RESULTS MTX significantly reduced IL-6 and sIL-2R after 12 weeks of therapy, and although the levels remained low at 24 weeks of therapy, the reduction was not significant. Reduction in cytokine levels was paralleled by an improvement in clinical indices. Placebo treatment did not significantly alter IL-6 or sIL-2R. CONCLUSION MTX appears capable of cytokine modulation, although the mechanism is not clear.

Abstract
OBJECTIVE To investigate the effect of cyclosporin A (CyA) therapy on circulating concentrations of interleukin-6 (IL-6) and soluble interleukin-2 receptor (sIL-2R) in patients with rheumatoid arthritis (RA). METHODS Twenty four RA patients with active disease were studied. Plasma was collected before and after 16 weeks of CyA treatment. IL-6 was measured by B9 bioassay and sIL-2R by enzyme linked immunosorbent assay (ELISA). RESULTS The initial median IL-6 concentration of 165 IU/ml decreased significantly to 71 IU/ml after 16 weeks (p < 0.05). Similarly, the initial median plasma sIL-2R value of 665 U/ml decreased significantly to 570 U/ml (p < 0.05). This decrease was accompanied by an improvement in clinical parameters of disease activity. Some association between sIL-2R, IL-6, haemoglobin, and platelets was also observed. CONCLUSIONS This study has demonstrated that, in vivo, CyA therapy in RA can significantly reduce circulating concentrations of IL-6 and sIL-2R. Modulation of both T and non-T cell derived cytokines may be one mechanism by which CyA improves rheumatoid disease. Whether this is a direct effect of CyA on the cells within the rheumatoid joint producing these cytokines or an indirect effect mediated by other cytokines which can influence IL-6 and Il-2R values remains to be determined.
