Neuropsychiatric events at the time of diagnosis of systemic lupus erythematosus: an international inception cohort study.

OBJECTIVE: To describe the prevalence, characteristics, attribution, and clinical significance of neuropsychiatric (NP) events in an international inception cohort of systemic lupus erythematosus (SLE) patients. METHODS: The study was conducted by the Systemic Lupus International Collaborating Clinics (SLICC). Patients were enrolled within 15 months of fulfilling the American College of Rheumatology (ACR) SLE classification criteria. All NP events within a predefined enrollment window were identified using the ACR case definitions of 19 NP syndromes. Decision rules were derived to determine the proportion of NP disease attributable to SLE. Clinical significance was determined using the Short Form 36 (SF-36) Health Survey and the SLICC/ACR Damage Index (SDI). RESULTS: A total of 572 patients (88% female) were recruited, with a mean +/- SD age of 35 +/- 14 years. The mean +/- SD disease duration was 5.2 +/- 4.2 months. Within the enrollment window, 158 of 572 patients (28%) had at least 1 NP event. In total, there were 242 NP events that encompassed 15 of 19 NP syndromes. The proportion of NP events attributed to SLE varied from 19% to 38% using alternate attribution models and occurred in 6.1-11.7% of patients. Those with NP events, regardless of attribution, had lower scores on the SF-36 and higher SDI scores compared with patients with no NP events. CONCLUSION: Twenty-eight percent of SLE patients experienced at least 1 NP event around the time of diagnosis of SLE, of which only a minority were attributed to SLE. Regardless of attribution, the occurrence of NP events was associated with reduced quality of life and increased organ damage.

The persistence of anticardiolipin antibodies is associated with an increased risk of the presence of lupus anticoagulant and anti-beta2-glycoprotein I antibodies.

OBJECTIVE: We studied antiphospholipid antibodies (aPL) in blood samples from a cohort of individuals followed for thrombosis to determine whether the persistent presence of anticardiolipin antibodies (aCL) is associated with a greater likelihood of having lupus anticoagulant and/or anti-beta2-glycoprotein I antibodies (LA/abeta2GPI). METHODS: Blood samples from 353 individuals who had been tested for aCL on at least two occasions were tested for abeta2GPI and LA. Two groups were defined: aCL-persistent, who tested aCL-positive on at least two occasions, and aCL non-persistent, who tested aCL-positive on fewer than two occasions. Multivariate logistic regressions were performed using LA/abeta2GPI, LA and abeta2GPI as outcome variables and the percentage of aCL-positive tests as the predictor variable, adjusted for age, gender, family history of cardiovascular disease (CVD), systemic lupus erythematosus (SLE), smoking and number of venous (VT) and arterial thromboses (AT). RESULTS: Sixty-eight (19%) individuals were aCL persistent and 285 (81%) were aCL non-persistent. LA/abeta2GPI was found in 36 (53%) of the aCL persistent group and 38 (13%) of the aCL non-persistent group. The two groups were similar for age, gender and smoking. Family history of CVD, SLE, VT and AT were more frequent in the aCL persistent group. Multivariate analyses revealed that odds ratios for LA/abeta2GPI, LA and abeta2GPI were 1.34 [95% confidence interval (CI) = 1.22-1.47], 1.36 (95% CI = 1.24-1.50) and 1.47 (95% CI = 1.31-1.65) respectively for each 10% increase in aCL-positive tests vs 0% positive tests. CONCLUSION: Persistence of aCL positivity is associated with an increased risk of LA/abeta2GPI.

Mortality in systemic lupus erythematosus.

OBJECTIVE: To examine mortality rates in the largest systemic lupus erythematosus (SLE) cohort ever assembled. METHODS: Our sample was a multisite international SLE cohort (23 centers, 9,547 patients). Deaths were ascertained by vital statistics registry linkage. Standardized mortality ratio (SMR; ratio of deaths observed to deaths expected) estimates were calculated for all deaths and by cause. The effects of sex, age, SLE duration, race, and calendar-year periods were determined. RESULTS: The overall SMR was 2.4 (95% confidence interval 2.3-2.5). Particularly high mortality was seen for circulatory disease, infections, renal disease, non-Hodgkin's lymphoma, and lung cancer. The highest SMR estimates were seen in patient groups characterized by female sex, younger age, SLE duration <1 year, or black/African American race. There was a dramatic decrease in total SMR estimates across calendar-year periods, which was demonstrable for specific causes including death due to infections and death due to renal disorders. However, the SMR due to circulatory diseases tended to increase slightly from the 1970s to the year 2001. CONCLUSION: Our data from a very large multicenter international cohort emphasize what has been demonstrated previously in smaller samples. These results highlight the increased mortality rate in SLE patients compared with the general population, and they suggest particular risk associated with female sex, younger age, shorter SLE duration, and black/African American race. The risk for certain types of deaths, primarily related to lupus activity (such as renal disease), has decreased over time, while the risk for deaths due to circulatory disease does not appear to have diminished.

Mortality related to cerebrovascular disease in systemic lupus erythematosus.

The objective of this study was to examine mortality rates related to cerebrovascular disease in systemic lupus erythematosus (SLE) compared to the general population. Our sample was a multisite Canadian SLE cohort (10 centres, n = 2688 patients). Deaths due to cerebrovascular disease were ascertained by vital statistics registry linkage using ICD diagnostic codes. Standardized mortality ratio (SMR, ratio of deaths observed to expected) estimates were calculated. The total SMR for death due to cerebrovascular disease was 2.0 (95% confidence interval [CI] 1.0, 3.7). When considering specific types of events, the category with the greatest increased risk was that of ill-defined cerebrovascular events (SMR 44.9 95% CI 9.3, 131.3) and other cerebrovascular disease (SMR 8.4, 95% CI 2.3, 21.6). Deaths due to cerebral infarctions appeared to be less common than hemorrhages and other types of cerebrovascular events. Our data suggest an increase in mortality related to cerebrovascular disease in SLE patients compared to the general population. The large increase in ill-defined cerebrovascular events may represent cases of cerebral vasculitis or other rare forms of nervous system disease; alternately, it may reflect diagnostic uncertainty regarding the etiology of some clinical presentations in SLE patients. The suggestion that more deaths are attributed to cerebral hemorrhage, as opposed to infarction, indicates that inherent or iatrogenic factors (eg, thrombocytopenia or anticoagulation) may be important. In view of the paucity of large-scale studies of mortality attributed to neuropsychiatric outcomes in SLE, our findings highlight the need for additional research in large SLE cohorts.

The systemic lupus erythematosus tri-nation study: longitudinal changes in physical and mental well-being.

OBJECTIVE: We have shown that SLE patients in Canada and the UK incurred 20% and 13% lower health costs than those in the US, respectively, but did not experience worse outcomes as expressed by the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index. We now compare change in quality of life in these patients. PATIENTS AND METHODS: Seven hundred and fifteen SLE patients (Canada 231, US 269, UK 215) completed the SF-36 annually over four years. The annual change in the SF-36 Physical and Mental Component Summary (PCS and MCS) scores over the course of the study were summarized by estimating a linear trend for each individual patient using hierarchical modelling. Cross-country comparison of the slopes in the PCS and MCS scores was then performed using simultaneous regressions. RESULTS: The estimated mean annual changes (95% credible interval [CrI]) in the PCS scores in Canada, the US, and the UK were 0.18 (-0.07, 0.43), -0.05 (-0.27, 0.17), and 0.03 (-0.20, 0.27), respectively; the mean annual changes in the MCS scores were 0.15 (-0.04, 0.34), 0.23 (0.09, 0.37), and 0.08 (-0.10, 0.27), respectively. Regression results showed that the mean annual changes in PCS and MCS scores did not substantially differ across countries. CONCLUSION: Quality of life remained stable across countries. Despite Canadian and British patients incurring lower health costs, on average, patients experienced similar changes in physical and mental well-being.

An international cohort study of cancer in systemic lupus erythematosus.

OBJECTIVE: There is increasing evidence in support of an association between systemic lupus erythematosus (SLE) and malignancy, but in earlier studies the association could not be quantified precisely. The present study was undertaken to ascertain the incidence of cancer in SLE patients, compared with that in the general population. METHODS: We assembled a multisite (23 centers) international cohort of patients diagnosed as having SLE. Patients at each center were linked to regional tumor registries to determine cancer occurrence. Standardized incidence ratios (SIRs) were calculated as the ratio of observed to expected cancers. Cancers expected were determined by multiplying person-years in the cohort by the geographically matched age, sex, and calendar year-specific cancer rates, and summing over all person-years. RESULTS: The 9,547 patients from 23 centers were observed for a total of 76,948 patient-years, with an average followup of 8 years. Within the observation interval, 431 cancers occurred. The data confirmed an increased risk of cancer among patients with SLE. For all cancers combined, the SIR estimate was 1.15 (95% confidence interval [95% CI] 1.05-1.27), for all hematologic malignancies, it was 2.75 (95% CI 2.13-3.49), and for non-Hodgkin's lymphoma, it was 3.64 (95% CI 2.63-4.93). The data also suggested an increased risk of lung cancer (SIR 1.37; 95% CI 1.05-1.76), and hepatobiliary cancer (SIR 2.60; 95% CI 1.25, 4.78). CONCLUSION: These results support the notion of an association between SLE and cancer and more precisely define the risk of non-Hodgkin's lymphoma in SLE. It is not yet known whether this association is mediated by genetic factors or exogenous exposures.

Non-Hodgkin's lymphoma in systemic lupus erythematosus.

BACKGROUND: Recent evidence supports an association between systemic lupus erythematosus (SLE) and non-Hodgkin's lymphoma (NHL). OBJECTIVES: To describe demographic factors, subtypes, and survival of patients with SLE who develop NHL. METHODS: A multi-site cohort of 9547 subjects with definite SLE was assembled. Subjects at each centre were linked to regional tumour registries to determine cancer cases occurring after SLE diagnosis. For the NHL cases ascertained, descriptive statistics were calculated, and NHL subtype frequency and median survival time of patients determined. RESULTS: 42 cases of NHL occurred in the patients with SLE during the 76,948 patient-years of observation. The median age of patients at NHL diagnosis was 57 years. Thirty six (86%) of the 42 patients developing NHL were women, reflecting the female predominance of the cohort. In the patients, aggressive histological subtypes appeared to predominate, with the most commonly identified NHL subtype being diffuse large B cell (11 out of 21 cases for which histological subtype was available). Twenty two of the patients had died a median of 1.2 years after lymphoma diagnosis. CONCLUSIONS: These data suggest aggressive disease in patients with SLE who develop NHL. Continuing work should provide further insight into the patterns of presentation, prognosis, and aetiology of NHL in SLE.

The systemic lupus erythematosus Tri-nation Study: absence of a link between health resource use and health outcome.

OBJECTIVE: Health consumption and health status in SLE in three countries with different health funding structures were compared. METHODS: Seven hundred and fifteen SLE patients (Canada 231, USA 269, UK 215) were surveyed semi-annually over 4 yr for health resource utilization and health status. Cross-country comparisons of (i) cumulative health expenditure (calculated by applying 2002 Canadian prices to resources in all countries) and (ii) disease damage (Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index, SLICC/ACR DI) at study conclusion were performed after adjustment. Missing expenditure and damage data were managed through multiple imputation using best predictive regressions with all available data from all patients as potential covariates. RESULTS: Four hundred and eighty-five patients provided data at study entry and conclusion and at least four resource questionnaires (Canada 162, USA 157, UK 166); 41 died (Canada 13, USA 18, UK 10); 189 withdrew, were lost to follow-up or provided data at entry and conclusion but fewer than four resource questionnaires (Canada 56, USA 94, UK 39). At conclusion, after imputation, in Canada, the USA and the UK respectively, mean cumulative costs per patient over 4 yr [95% confidence interval (CI)] were $15,845 (13,509, 18,182), $20,244 (17,764, 22,724) and $17,647 (15,557, 19,737) and mean changes in SLICC/ACR DI were 0.49 (0.39, 0.60), 0.63 (0.52, 0.74) and 0.48 (0.39, 0.57). After adjustment for baseline differences, on average (95% CI), Canadian and British patients utilized 20% (8%, 32%) and 13% (1%, 24%) less resources than patients in the USA respectively, but experienced similar health outcomes. CONCLUSION: Despite patients in the USA incurring higher health expenditures, they did not experience superior health outcomes.

Validation of a Systemic Lupus Activity Questionnaire (SLAQ) for population studies.

The goal of this work was to develop an economical way of tracking disease activity for large groups of systemic lupus erythematosus (SLE) patients in clinical studies. A Systemic Lupus Activity Questionnaire (SLAQ) was developed to screen for possible disease activity using items from the Systemic Lupus Activity Measure (SLAM) and tested for its measurement properties. The SLAQ was completed by 93 SLE patients just prior to a scheduled visit. At the visit, a rheumatologist, blinded to SLAQ results, examined the subject and completed a SLAM. Associations among SLAQ, and SLAM (omitting laboratory items) and between individual items from each instrument were assessed with Pearson correlations. Correlations between pairs of instruments were compared using Student's t-tests. The mean score across all 24 SLAQ items was 11.5 (range 0-33); mean SLAM without labs was 3.0 (range 0-13). The SLAQ had a moderately high correlation with SLAM-nolab (r = 0.62, P < 0.0001). Correlations between patient-clinician matched pairs of items ranged from r = 0.06 to 0.71. Positive predictive values for the SLAQ ranged from 56 to 89% for detecting clinically significant disease activity. In studies of SLE, symptoms suggesting disease can be screened by self-report using the SLAQ and then verified by further evaluation.

Traditional Framingham risk factors fail to fully account for accelerated atherosclerosis in systemic lupus erythematosus.

OBJECTIVE: The frequency of coronary heart disease (CHD) and stroke are increased in systemic lupus erythematosus (SLE), but the extent of the increase is uncertain. We sought to determine to what extent the increase could not be explained by common risk factors. METHODS: The participants at two SLE registries were assessed retrospectively for the baseline level of the Framingham study risk factors and for the presence of vascular outcomes: nonfatal myocardial infarction (MI), death due to CHD, overall CHD (nonfatal MI, death due to CHD, angina pectoris, and congestive heart failure due to CHD), and stroke. For each patient, the probability of the given outcome was estimated based on the individual's risk profile and the Framingham multiple logistic regression model, corrected for observed followup. Ninety-five percent confidence intervals (95% CIs) were estimated by bootstrap techniques. RESULTS: Of 296 SLE patients, 33 with a vascular event prior to baseline were excluded. Of the 263 remaining patients, 34 had CHD events (17 nonfatal MIs, 12 CHD deaths) and 16 had strokes over a mean followup period of 8.6 years. After controlling for common risk factors at baseline, the increase in relative risk for these outcomes was 10.1 for nonfatal MI (95% CI 5.8-15.6), 17.0 for death due to CHD (95% CI 8.1-29.7), 7.5 for overall CHD (95% CI 5.1-10.4), and 7.9 for stroke (95% CI 4.0-13.6). CONCLUSION: There is a substantial and statistically significant increase in CHD and stroke in SLE that cannot be fully explained by traditional Framingham risk factors alone.

The relationship between health related quality of life and disease activity and damage in systemic lupus erythematosus.

OBJECTIVE: To evaluate the relationship between self-reported quality of life and disease activity, damage, impairment, disability, and handicap in systemic lupus erythematosus (SLE). METHODS: In this cross sectional study disease activity was measured with the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and the Systemic Lupus Activity Measure (SLAM), and damage by the Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) damage index (SDI). Quality of life was assessed by the Medical Outcome Survey Short Form 36 (SF-36) and the EuroQol (EQ-5D). Multiple linear regression was used to identify significant associations of patients' health status, and logistic regression was used to evaluate the relationship of each of the 5 dimensions of the EQ-5D in terms of impairment, disability, and handicap. RESULTS: Damage was associated with the Physical Function (PF) and Social Function subscales of the SF-36. Disease activity was associated with the General Health (GH) subscale. Ability to carry out usual activities was strongly related to PF and GH as well as to global rating of the thermometer rating scale of the EQ-5D. Role Physical (RP) and Bodily Pain (BP) of the SF-36 were also associated with the EQ-5D rating scale. In addition, patients' ratings of anxiety and depression were strongly related to the Mental Health (MH) summary scale of the SF-36. CONCLUSION: Perceived health status of patients with lupus was associated with disease activity, damage, role physical, bodily pain, capacity for usual activity, and mobility. EQ-5D is a valid instrument for the measure of health related quality of life in SLE.

Adaptation and validation of the rheumatoid arthritis quality of life scale for use in Canada.

OBJECTIVE: The Rheumatoid Arthritis Quality of Life questionnaire (RAQoL) was developed simultaneously in the UK and the Netherlands to measure quality of life in patients with RA. We adapted and validated the RAQoL for the English-Canadian and French-Canadian languages and culture. METHODS: The UK RAQoL was translated into French-Canadian by a bilingual translation panel. Separate lay panels were then used to ensure that this and the English-Canadian instruments were appropriate for use with Canadian patients. Interviews were conducted with 15 French-Canadian and 15 English-Canadian patients with RA to determine the content validity. Reliability and construct validity were established by means of test-retest mail surveys conducted with 92 French-Canadian and 87 English-Canadian RA patients. The survey consisted of the adapted RAQoL, the Health Assessment Questionnaire (HAQ), and a demographic questionnaire. RESULTS: The RAQoL was successfully adapted for both the French and English-Canadian cultures. Field testing showed both versions to be well received by respondents. Of the French-Canadian patients included in the postal survey, 52 responded at Time 1 and 50 at Time 2. For the English-Canadian sample, 54 responded at both time points. Missing data rates for the RAQoL were low and floor and ceiling effects were minimal. Test-retest reliability was good for both versions: 0.87 for the French-Canadian and 0.95 for the English-Canadian. Alpha coefficients (0.92 for the French-Canadian, 0.93 for the English-Canadian) showed the items to be adequately interrelated and scores on the measure showed moderate to high correlations with the HAQ, confirming construct validity. Both versions of the RAQoL were also able to distinguish patient groups that differed according to perceived health status and perceived severity of RA. In addition, the French-Canadian version was able to distinguish patients who rated today as bad or very bad from those who rated today as good or very good. CONCLUSION: The new versions of the RAQoL were well received by both French and English speaking Canadians. The psychometric quality of the adapted questionnaires means they are suitable for inclusion in clinical trials involving patients with RA.

Living with lupus: a prospective pan-Canadian study.

OBJECTIVE: To portray life with lupus for women affected by this disease and to identify predictors of fatigue, a common symptom that compromises patients' quality of life. METHODS: A sample of 120 female patients (mean age 42.5 yrs) with systemic lupus erythematosus (SLE) from 9 rheumatology clinics across Canada were followed prospectively for 15 months. Assessments of psychosocial functioning took place at baseline, and at 3, 9, and 15 months. Physician examinations were conducted at baseline and 15 months. RESULTS: Significant time effects were found for: global psychological distress (p < 0.001), stress (p < 0.01), emotion-oriented coping (p < 0.001), physical health status (p < 0.001), and fatigue (p < 0.001), indicating that patients improved from baseline to 15 months. Disease activity worsened for 40.3%, improved for 50.8%, and remained the same for 8.8% of the patients from baseline to 15 months. Controlling for baseline disease activity and fatigue, and considering sleep problems, decreases in stress and depression predicted less fatigue at 15 months (p < 0.001; adjusted R2 = 0.43). CONCLUSION: Despite fluctuations in disease activity, patients with SLE, as a group, cope adequately with their disease over time. There is, nonetheless, a subset of patients (about 40%) who remain distressed and who may benefit from psychosocial interventions.

The use of alternative medical therapies in patients with systemic lupus erythematosus. Trination Study Group.

OBJECTIVE: As part of an ongoing study of health resource utilization and diminished productivity in patients with systemic lupus erythematosus (SLE), the use of alternative medical therapies was assessed. METHODS: A cohort of 707 patients with SLE from 3 countries completed questionnaires on demographics, social support, health status (using the Short Form 36 health survey), satisfaction with health care, health resource utilization (conventional resources and alternative therapies), and time losses in labor market and non-labor market activities. Annual direct and indirect costs (1997 Canadian dollars) were calculated and compared for users and nonusers of alternative medical therapies. RESULTS: Among the 707 patients, 352 (49.8%) were found to use alternative therapies and at similar rates across Canada, the United States, and the United Kingdom. Users were younger and better educated than nonusers, exhibited poorer levels of self-rated health status and satisfaction with medical care, and had minimal to no objective evidence of worse disease (according to the revised Systemic Lupus Activity Measure instrument). The mean of log direct medical costs for conventional resources was higher for users of select alternative therapies compared with nonusers. In a logistic regression, neither the number of alternative therapies used nor the individual therapy increased the probability of incurring indirect costs. CONCLUSION: The use of alternative medical therapies is common in patients with SLE. Users of many alternative medical therapies accrue greater conventional medical costs compared with nonusers. The use of alternative medical therapy may be a marker for care-seeking behavior associated with higher consumption of conventional medical resources in the absence of demonstrable additional morbidity and should be considered in future cost analyses of patients with SLE.

Association between IgM response to IgG damaged by glyoxidation and disease activity in rheumatoid arthritis.

OBJECTIVE: To determine the association of serum IgG advanced glycation endproducts (AGE) and IgM anti-IgG-AGE antibodies with clinical measurements of rheumatoid arthritis (RA) disease activity. METHODS: The study group consisted of 62 patients with RA and 16 control patients with osteoarthritis. Patient derived variables included perceived disease activity (10 cm visual analog scale, VAS) and Health Assessment Questionnaire (HAQ) results. Clinical measures of RA activity consisted of tender and swollen joint counts and a physician evaluation of disease activity (by VAS) as well as history of nodules, bone erosions, Sjogren's syndrome, and vasculitis documented by chart review. Patient sera were evaluated for glucose, glycosylated hemoglobin, and presence of RF, IgG-AGE and IgM anti-IgG-AGE. The nitroblue tetrazolium colorimetric and aminophenyl boronic acid methods were used for measurement of IgG-AGE, along with an ELISA for measurement of IgM anti-IgG-AGE. RESULTS: Significant correlations were found between the presence of IgM anti-IgG-AGE and clinical measurements of swollen joint count and physician VAS. CONCLUSION: IgM anti-IgG-AGE appears to be associated with clinical measurements of RA activity and represents a new marker of more active disease in RA.

Determinants of health status in fibromyalgia: a comparative study with systemic lupus erythematosus.

OBJECTIVE: To compare perceived health status in women with fibromyalgia (FM) and systemic lupus erythematosus (SLE) using the Medical Outcomes Study (MOS) Short Form Health Survey (SF-36); and to identify determinants of physical and mental health in each patient group. METHODS: A cross sectional study of 46 women with FM (mean age 48.13 yrs, SD 9.40) and 59 women with SLE (mean age 42.36 yrs, SD 11.31). Patients with FM were recruited from a rheumatology clinic and a rheumatology practice, while patients with SLE were recruited from 4 rheumatology clinics. Clinical examination determined disease activity (by Systemic Lupus Activity Measure) in SLE and a tender point count was used for FM. Patients completed questionnaires assessing health status (SF-36), stress (Hassles), social support (Social Support Questionnaire 6), and coping (Coping Inventory for Stressful Situations). RESULTS: Patients with FM reported more impairment on the following SF-36 subscales: physical function (p < 0.001), role physical (p < 0.001), bodily pain (p < 0.001), and vitality (p < 0.001). Physical component summary scores were also significantly lower (p < 0.001) for the FM group. Four hierarchical regression analyses were computed to determine factors related to physical and mental health in each patient group, with the following variables in the equation: age, income, disease activity (Step 1), hassles (Step 2), emotional and task coping, and social support (Step 3). Better physical health in FM was related to higher income (R2 = 0.17, p < 0.05). In the SLE group, better physical health was associated with younger age, less disease activity, and lower hassles (R2 = 0.37, p < 0.0001). Worse mental health among women with FM was associated with more hassles, more emotional coping, and less satisfaction with social support (R2 = 0.64, p < 0.0001), while lower income, higher hassles, and more emotional coping were linked to worse mental health in SLE (R2 = 0.46, p < 0.0001). CONCLUSION: Health related quality of life (HRQL) is impaired among women with FM and SLE, with FM patients reporting greater impairment along several dimensions. Enhancing the HRQL of patients with FM and SLE requires targeting specific modifiable psychosocial factors.

Learning from discordance in patient and physician global assessments of systemic lupus erythematosus disease activity.

OBJECTIVE: Differences have been described between patient and physician assessments of well being in several chronic illnesses, and these differences may affect outcome. Disagreement may lead to dissatisfaction and to behaviors with dangerous consequences. We describe and identify predictors of patient-physician differences on ratings of disease activity in systemic lupus erythematosus (SLE). METHODS: Data collected on 154 patients included age, education, disease duration, and patient and physician global assessments of lupus activity on a 10 cm visual analog scale (VAS), the Health Assessment Questionnaire (HAQ), the Medical Outcome Study Short-Form 36 (SF-36), the Systemic Lupus Disease Activity Index (SLEDAI), the Systemic Lupus Activity Measure (SLAM-R), and the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI). Multiple linear regression models were performed using patient VAS scores, physician VAS scores, and patient minus physician VAS scores as the dependent variables, and age, disease duration, selected SF-36 and SLAM-R subscales, and SDI as independent variables. RESULTS: Patients were 90% female and 80% Caucasian, with a mean education of 13 +/- 2.8 years and a mean age of 43.1 +/- 13.6 years. The overall mean disease duration was 10.5 +/- 7.8 years. Physicians overscored patients by 2.5 cm in 6% of the cases and patients overscored physicians in 16% of the cases. The best multivariate model to predict overall differences included SF-36 mental health and SLAM-R kidney scores. CONCLUSION: Patient-physician differences may result from a divergence in focus. Patients score lupus activity based on their psychological status, while physicians rely more heavily on the physical effect of the disease.
