Systemic lupus erythematosus in a multiethnic US cohort (LUMINA) XL II: factors predictive of new or worsening proteinuria.

OBJECTIVES: To determine the factors predictive of new or worsening proteinuria in a large multiethnic cohort of patients with systemic lupus erythematosus (SLE). METHODS: Five hundred and twenty-nine SLE patients from a multiethnic US cohort [LUpus in MInorities: NAture versus Nurture (LUMINA)] were evaluated for new or worsening proteinuria using the categories of the Systemic Lupus Activity Measure-Revised: (1), normal; (2), trace or 1+ proteinuria on the dipstick; (3), 2-3+ proteinuria and (4), > or =4+ proteinuria. A rise in urinary protein was considered a positive event visit. Basic demographic and socioeconomic variables were assessed at baseline (T0). Clinical and immunological variables including disease features, activity, duration, comorbidities (such as hypertension and diabetes), medications and autoantibodies were assessed at the visit preceding a positive event visit. Selected HLA-DR and HLA-DQ alleles, and FCGR receptor polymorphisms were assessed. Data were analysed using logistic regression analyses and generalized estimating equations. RESULTS: There were 243 patients (59.1% of 93 Texan Hispanics, 37.0% of 100 Puerto Rican Hispanics, 58.0% of 181 African Americans and 29.7% of 155 Caucasians) with new or worsening proteinuria, and 364 positive events in 2801 visits. Younger age [Odds ratio (OR) = 1.013, 95% confidence limits (CL) = 1.001-1.024, P < 0.0334], anti-dsDNA (OR = 1.554, CL = 1.149-2.100, P < 0.0042), and HLA-DRB1*1503 (OR = 1.746, 95% CL = 1.573-2.2673, P < 0.0103) were found to independently predict the occurrence of new or worsening proteinuria. CONCLUSION: The factors predictive of new or worsening proteinuria include traditional factors associated with lupus nephritis, such as age and anti-dsDNA, as well as HLA-DRB1*1503, which has not been previously described in association with lupus nephritis, new or worsening proteinuria.

Predictors of post-partum damage accrual in systemic lupus erythematosus: data from LUMINA, a multiethnic US cohort (XXXVIII).

OBJECTIVE: To determine the impact of pregnancy on systemic lupus erythematosus (SLE) outcome. METHODS: SLE patients, age >or=16 yrs, disease duration <or=5 yrs at enrolment in LUMINA, a multiethnic cohort (Hispanics, African-Americans and Caucasians), were studied. The first pregnancy after SLE diagnosis was examined. A good pregnancy outcome was a full-term delivery; an adverse outcome was a miscarriage, abortion, premature birth or stillbirth. Dependent variables were disease activity (Systemic Lupus Activity Measure-Revised, SLAM-R) and damage accrual [Systemic Lupus International Collaborating Clinics (SLICC) Damage Index, SDI]. Differences in these variables between the visit immediately prior to, and the first visit after, pregnancy and their relationship with pregnancy outcome were examined. Damage accrual due to pregnancy exposure was examined by a case-crossover design. RESULTS: Sixty-three SLE women from all ethnic groups were included. The mean (S.D.) age and disease duration at pregnancy outcome were 27.6 (6.5) yrs and 18.3 (22.5) months, respectively. Adverse pregnancy outcomes occurred in 76.2% women. The SLAM-R and SDI scores were statistically different after pregnancy (P = 0.050 and P < 0.001, respectively); the SDI score was independent of pregnancy outcome but strongly associated with pregnancy duration (P = 0.006), disease activity (P = 0.001), damage prior to pregnancy (P < 0.001) and total disease duration (P = 0.039) by multivariable analyses. Exposure to pregnancy itself did not impact on damage accrual in the case-crossover analyses of 142 patients (17 pregnancy exposures) (OR = 1.25; 95% CI 0.336-4.655; P = 0.480). CONCLUSIONS: Pregnancy duration, total disease duration, disease activity and damage immediately prior to pregnancy decisively impact on damage accrual after pregnancy in patients with SLE.

Systemic lupus erythematosus in a multiethnic US cohort LUMINA (XLI): factors predictive of self-reported work disability.

OBJECTIVE: To examine the risk factors for self-reported work disability in patients from the LUpus in MInorities: NAture vs. Nurture cohort with systemic lupus erythematosus (SLE). METHODS: Patients with SLE of Hispanic (Texas and Puerto Rico), African American and Caucasian ethnicity were studied. Work disability was defined by patients' self-report. Only patients known to be employed at the baseline visit were included. The probabilities of self-reporting work disability over time were examined by the Kaplan-Meier method; differences between ethnic groups were examined by the log-rank test. The relationship of baseline socioeconomic-demographic, clinical, behavioural and psychological features with work disability was examined by standard statistical tests. Variables with p<or=0.10 in these analyses were examined by logistic regression. RESULTS: The rate of self-reported work disability among the 273 patients studied was 19% at 5 years; it was numerically higher for the African Americans (25%) than for the Hispanics from Texas (19%) and the Caucasians (18%). The rate for the Hispanics from Puerto Rico was 7% at 2 years; 5-year rates could not be estimated for this ethnic subgroup (shorter follow-up in the cohort). In the regression analysis, age, male sex, poverty, total disease duration, disease activity and damage accrual were predictors of work disability. CONCLUSIONS: The rate of work disability was 19% at 5 years. Patients with SLE with more severe disease and with lower socioeconomic status are at high risk of becoming disabled. The toll SLE imposes could possibly be reduced in patients at risk if, in addition to medical treatment, services needed to overcome their disadvantageous socioeconomic status are provided.

Systemic lupus erythematosus in a multiethnic cohort: LUMINA XXXV. Predictive factors of high disease activity over time.

AIM: To ascertain the predictive factors of high levels of disease activity in systemic lupus erythematosus (SLE). PATIENTS AND METHODS: Patients with SLE (American College of Radiology criteria), aged >or=16 years, with disease duration 10). A basic multivariable model (including age, sex, ethnicity, health insurance, social support, abnormal illness-related behaviours, helplessness and prior disease activity) was first examined. Additional models were built by including other variables. RESULTS: 554 patients (100 Hispanics from Texas, 94 Hispanics from Puerto Rico, 199 African Americans, 161 Caucasians) and 2366 visits were analysed; 47% of the patients and 29% of the visits met the definition of high disease activity (more common among African Americans (72.0%) and Hispanics from Texas (71.3%) than among Caucasians (43.9%) and Hispanics from Puerto Rico (31.9%)). Variables found to predict high levels of disease activity were Hispanic (from Texas) and African American ethnicities, lack of health insurance, helplessness, abnormal illness-related behaviours and poor social support; age was negatively associated with high levels of disease activity. African admixture and anti-double-stranded DNA antibodies also predicted high levels of disease activity, as did prior disease activity. None of the human leucocyte antigen variables were retained in the models. CONCLUSIONS: Socioeconomic-demographic (age, ethnicity, health insurance), behavioural and psychological variables are important mediators of high levels of disease activity in SLE during its course. Interventions aimed at modifiable factors may improve the outcomes of SLE.

Systemic lupus erythematosus in a multiethnic U.S. cohort (LUMINA) XXVII: factors predictive of a decline to low levels of disease activity.

The objective of this study was to examine factors predictive of a decline to low levels of disease activity in a cohort of systemic lupus erythematosus (SLE) patients. Patients with SLE of Hispanic (from Texas or Puerto Rico), African-American or Caucasian ethnicity from a multiethnic cohort were included. A decline to low levels of disease activity was defined as a score < or =5 as per the Systemic Lupus Activity Measure-Revised (SLAM-R) at any annual study visit if preceded by a SLAM-R > or =8. Using Generalized Estimating Equation (GEE), socioeconomic-demographic, behavioral, function, psychological, laboratory and clinical data [disease manifestations, number of ACR criteria accrued at diagnosis and damage accrual as per the Systemic Lupus International Collaborating Clinics (SLICC) Damage Index (SDI)] from the visit preceding that meeting the definition were examined as predictors of decline to low levels of disease activity. Two-hundred and eighty-seven patients (67 Hispanics from Texas, 32 Hispanics form Puerto Rico, 120 African-Americans and 68 Caucasians), accounting for 632 visits were analyzed. In the GEE multivariable analysis, higher degrees of social support (OR = 1.208, 95% CI 1.059-1.379; P = 0.005) were predictive of a decline to low levels of disease activity, while the number of ACR criteria accrued at diagnosis (OR = 0.765, 95% CI 0.631-0.927; P = 0.006) and damage (OR = 0.850, 95% CI 0.743-0.972, P = 0.018) were negatively associated. These data suggest that a decline to low levels of disease activity in lupus patients seems to be multifactorial; this study also underscores the importance of social support for lupus patients.

Systemic lupus erythematosus in a multiethnic U.S. cohort (LUMINA) XXXI: factors associated with patients being lost to follow-up.

The objective of this study was to determine the frequency of loss to follow-up and the factors predictive of its occurrence in a systemic lupus erythematosus (SLE) multiethnic cohort. We studied SLE patients from the LUMINA cohort (Hispanics from Texas and from the Island of Puerto Rico, African-Americans and Caucasians). Loss to follow-up was defined as subjects who failed to attend two or more of the latest consecutive yearly study visits. The relationship between baseline features and loss to follow-up was examined by univariable and multivariable Cox regression analyses with loss to follow-up as the dependent variable. The retention rate in the cohort was estimated by the Kaplan-Meier method. Five-hundred and fifty-four patients with a mean (SD) follow-up of 3.4 (2.9) years were studied. One-hundred and fifty-eight (29%) met the definition of lost to follow-up. The cumulative loss to follow-up rate at five years was 36%. The cumulative loss to follow-up rate at five years was higher for the African-Americans. Patients lost to follow-up tended to be younger and more likely to have poor social support and higher levels of helplessness. They also tended to have more renal involvement and more active disease as per the Systemic Lupus Activity Measure-Revised. Disease activity (hazard ratio = 1.04, 95% confidence interval 1.01-1.07, P = 0.02) was the only variable independently contributing to loss to follow-up. Our data suggest that in longitudinal SLE studies, loss to follow-up does not occur at random and it differs between ethnic groups and is also particularly higher among patients with more active disease. Pro-active measures may need to be applied to decrease the probability of patients 'at risk' of becoming lost to follow-up and to preserve the integrity of the cohort.

Systemic lupus erythematosus in a multiethnic US cohort (LUMINA): XXIV. Cytotoxic treatment is an additional risk factor for the development of symptomatic osteonecrosis in lupus patients: results of a nested matched case-control study.

BACKGROUND: Osteonecrosis is common in systemic lupus erythematosus (SLE) and often disabling. The role of glucocorticoids in its development is well known. OBJECTIVE: To explore other possible risk factors for osteonecrosis in SLE. METHODS: A nested matched case-control study undertaken in the context of a large, longitudinal, multiethnic lupus cohort (LUMINA), currently formed of 571 SLE patients meeting American College of Rheumatology criteria. All those developing symptomatic osteonecrosis after the diagnosis of SLE were considered cases. Two controls matched for age, disease duration, ethnicity, and centre were selected for each case. Cases and controls were compared by univariable analyses using selected variables. Variables with p<0.10 and those thought clinically relevant were entered into conditional logistic regression models including either the average dose or the highest dose of glucocorticoids, with osteonecrosis as the dependent variable. RESULTS: 32 cases were identified and 59 matched controls selected (in five cases only one control could be found). By univariable analyses, both groups were largely comparable for socioeconomic-demographic, clinical, and laboratory variables. Cases were less exposed to hydroxychloroquine (as assessed by the percentage of exposure time) (p = 0.026), used higher doses of glucocorticoids (average and highest doses) (p = 0.011 and 0.001, respectively), and received cytotoxic drugs more often (p = 0.015). In the multivariable analyses only cytotoxic drug use (both models) and the highest dose of glucocorticoids remained associated with the occurrence of osteonecrosis. CONCLUSIONS: Cytotoxic drug use is a risk factor for the development of symptomatic osteonecrosis in SLE patients, along with glucocorticoids. No definite protective factors were identified.

Systemic lupus erythematosus in a multiethnic cohort (LUMINA): XXVIII. Factors predictive of thrombotic events.

OBJECTIVE: To determine the relationship between the presence of antiphospholipid (aPL) antibodies, hydroxychloroquine use and the occurrence of thrombotic events in patients with systemic lupus erythematosus (SLE). METHODS: Four hundred and forty-two SLE patients from the LUMINA (Lupus in Minorities: Nature vs Nurture) cohort, a multiethnic (Hispanics from Texas, n = 99 and Puerto Rico, n = 36; African Americans, n = 172; and Caucasians, n = 135) cohort, were studied by generalized estimating equation (GEE) to determine the relationship between antiphospholipid (aPL) antibodies (measured as IgG and IgM aPL antibodies and/or the lupus anticoagulant) at enrolment or historically prior to enrolment, hydroxychloroquine use (ever) and the occurrence of thrombotic (central and/or peripheral, arterial and/or venous) events after adjusting for known and possible confounders [socioeconomic-demographic features, smoking, disease activity and damage, serum cholesterol levels, anti-oxidized low-density lipoprotein IgG and IgM antibodies, and high-sensitivity (hs) C-reactive protein]. Postanalysis correlation between aPL and anticardiolipin (aCL) assays was attempted by performing aCL assays on random samples of patients whose aPL status was known. RESULTS: A number of clinical variables were significant in the univariable analyses; however, in the multivariable GEE analyses, only smoking [odds ratio (OR) 2.777, 95% confidence interval (CI) 1.317-5.852] and disease activity as measured by the SLAM (Systemic Lupus Activity Measure) (OR 1.099; 95% CI 1.053-1.147) were significant. In particular, hydroxychloroquine use, which appeared to be protective against thrombotic events in the univariable analyses, was not retained in the multivariable analyses. aPL antibodies were not significant in either analysis. Few additional aPL-positive patients emerged from the validation study. CONCLUSIONS: Smoking and disease activity emerged as important determinants in the occurrence of thrombotic events in our patients. Comprehensive treatment strategies should be directed to both smoking cessation and control of disease activity in patients with SLE.

Lack of recording of systemic lupus erythematosus in the death certificates of lupus patients.

OBJECTIVE: To determine to what extent the diagnosis of systemic lupus erythematosus (SLE) in deceased lupus patients is under-reported in death certificates, and the patient characteristics associated with such an occurrence. METHODS: The death certificates of 76 of the 81 deceased SLE patients from two US lupus cohorts (LUMINA for Lupus in Minorities: Nature vs Nurture and CLU for Carolina Lupus Study), including 570 and 265 patients, respectively, were obtained from the Offices of Vital Statistics of the states where the patients died (Alabama, Georgia, North Carolina, South Carolina, Tennessee and Texas). Both cohorts included patients with SLE as per the American College of Rheumatology criteria, aged > or =16 yr, and disease duration at enrolment of < or =5 yr. The median duration of follow-up in each cohort at the time of these analyses ranged from 38.1 to 53.0 months. Standard univariable analyses were performed comparing patients with SLE recorded anywhere in the death certificate and those without it. A multivariable logistic regression model was performed to identify the variables independently associated with not recording SLE in death certificates. RESULTS: In 30 (40%) death certificates, SLE was not recorded anywhere in the death certificate. In univariable analyses, older age was associated with lack of recording of SLE in death certificates [mean age (standard deviation) 50.9 (15.6) years and 39.1 (18.6) yr among those for whom SLE was omitted and included on the death certificates, respectively, P = 0.005]. Patients without health insurance, those dying of a cardiovascular event and those of Caucasian ethnicity were also more likely to be in the non-recorded group. In the multivariable analysis, variables independently associated with not recording SLE as cause of death were older age [odds ratio = (95% confidence interval) 1.043 (1.005-1.083 per yr increase); P = 0.023] and lack of health insurance [4.649 (1.152-18.768); P = 0.031]. CONCLUSIONS: A high proportion of SLE diagnoses are not recorded in death certificates. Older patients and those without health insurance are more prone to have SLE not recorded. These findings do have implications for the assessment of the impact of this disease in epidemiological studies conducted using vital statistics records.

Systemic lupus erythematosus in a multiethnic US Cohort (LUMINA). XXX: association between C-reactive protein (CRP) gene polymorphisms and vascular events.

OBJECTIVES: To determine if a polymorphic GTn repeat in the intron of the C-reactive protein (CRP) gene associates with occurrence of vascular arterial events in systemic lupus erythematosus (SLE). METHODS: We performed a nested case-control study on the LUMINA cohort of 546 Hispanic, African-American and Caucasian SLE patients. Twenty-five patients who developed vascular arterial events (i.e. myocardial infarction, angina, coronary artery bypass graft surgery, stroke, claudication, gangrene or significant tissue loss and/or arterial peripheral thrombosis) after enrolment were selected as cases and 32 ethnically matched patients with no previous vascular arterial events served as controls. Their CRP gene GTn polymorphism and plasma CRP was determined. RESULTS: Patients with vascular events had more severe SLE and were more likely to have plasma CRP in the highest quintile of measured values. The overall distribution of GTn alleles for patients with vascular events had a greater number of the GT20 variant compared with controls [26.0% of alleles (13/50) vs 15.6% (10/64)]. This greater number of GT20 in patients with vascular events was observed for African-Americans [29.2% (7/24) vs 21.0% (8/38)] and Hispanics [33.0% (4/12) vs 0% (0/16)] but not for Caucasians [14.3% (2/14) vs 20.0% (2/10)]. For African-Americans and Hispanics combined (45 patients), the frequency of GT20 in those with vascular events (30.6%, 11/36) was significantly higher than in those without them (14.8%, 8/54) (P<0.05, one-tailed test for difference in proportions). When patients were categorized according to the number of GT20 alleles they carried (thus GT20/GT20, GT20/GTx or GTx/GTx, where x is any allele other than GT20), for both African-Americans and Hispanics the likelihood of vascular arterial events increased in proportion with the GT20 dose, and all GT20-homozygous patients developed vascular arterial events. CONCLUSIONS: The CRP GT20 variant is more likely to occur in African-American and Hispanic SLE patients than in Caucasian ones, and SLE patients carrying the GT20 allele are more likely to develop vascular arterial events.

Lack of association of matrix metalloproteinase 3 (MMP3) genotypes with ankylosing spondylitis susceptibility and severity.

OBJECTIVE: To study the linkage and association of ankylosing spondylitis (AS) with genotypes for matrix metalloproteinase 3 (MMP3), a gene located at chromosome 11q22.3 and lying within the 101-124 cM region observed in a recent genome-wide scan as a region associated with AS susceptibility. METHODS: MMP3 genotypes were examined in 229 pedigrees with AS, 131 sporadic AS cases and 87 Caucasian controls. Eight single-nucleotide polymorphisms (SNPs) were selected and genotyped using Taqman. Non-parametric linkage (NPL) analysis was conducted between the eight MMP3 SNPs and AS using the NPL-all statistic and two-point parametric linkage analysis using GeneHunter Plus. Unrelated AS cases and controls were compared using chi2 statistics, and family-based controls using the transmission disequilibrium test and pedigree disequilibrium test. RESULTS: None of the eight MMP3 SNPs were significantly associated with AS, either using the 131 sporadic cases alone or in analyses which combined these cases with the 226 unrelated affected AS patients derived from the pedigrees. Analysis of linkage disequilibrium (LD) demonstrated that seven of the eight SNPs studied were in strong LD except for rs626750, which is about 6 kb upstream of the 5' end of the gene. No significant linkage was observed using NPL and LODs in the families. No association was seen of any of the MMP3 SNPs with disease severity (defined by patient functioning), as measured either by the Bath Ankylosing Spondylitis Functional Index or the modified Health Assessment Questionnaire. CONCLUSION: These data suggest that MMP3 genotypes are not involved in AS susceptibility or severity.

Predictive value of autoantibodies for activity of systemic lupus erythematosus.

There is no serologic test that reliably measures disease activity in systemic lupus erythematosus (SLE). The 'gold standard' is the anti-dsDNA antibody test, which has been used as a marker of disease activity by clinicians in SLE for over 35 years. Anti-dsDNA antibodies perform best in those with lupus nephritis, specifically in the presence of a proliferative lesion [World Health Organization (WHO) class III or IV] on renal biopsy. In one recent meta-analysis, the mean positive likelihood ratio of anti-dsDNA antibodies as a marker of disease activity in SLE was 4.14, implying the overall predictive effect was small. More recently autoantibody assays have been developed that show greater promise in gauging SLE disease activity, specifically anti-nucleosome and anti-C1q antibodies (especially with renal disease activity). Other tests thought previously to be lacking in specificity that refinements in ELISA technology now render possibly useful include anti-heparan sulfate, anti-ssDNA and anti-Scl-70 autoantibodies. Other tests that as yet have not been shown to be as reliable (and therefore are not as useful in clinical practice for serial determination to measure disease activity) include other anti-extractable nuclear antibodies (anti-Ro, La, Sm, RNP), anti-cardiolipin antibodies, and anti-nuclear cytoplasmic antibodies (ANCA). New technologies using proteomic determinations show promise as aids in the search for more reliable and feasible autoantibody determinations of disease activity in SLE.

Relationship between adherence to study and clinic visits in systemic lupus erythematosus patients: data from the LUMINA cohort.

The aim of this study was to examine the relationship between nonadherence with study visits and with regularly scheduled clinic visits after adjusting for other patient and disease characteristics. One hundred and forty-one LUMINA patients with appointment data in the institutions' computerized systems (UAB and UTH) were studied. 'No shows' were assessed as the percentage of appointments not attended for either rheumatology, other clinics and LUMINA visits (from zero to 100%). Eighty-nine percent of the patients were women, 40% were Caucasians, 55% African-Americans and 5% Hispanics. 'No shows' to rheumatology were associated with non-Caucasian ethnicity, younger age, single marital status, lack of home ownership, 'no shows' to other clinics and to the LUMINA study, greater disease activity and to some disease manifestations (serositis, renal involvement, positive anti-dsDNA antibodies). In multivariable analyses, features predictive of rheumatology 'no shows' were lack of home ownership, 'no shows' to LUMINA study visits, renal involvement and serosal manifestations. Nonadherence with study visits and with regularly scheduled care at rheumatology clinics were associated. Other factors predictive of nonadherence to recommended care were lack of home ownership (a measurement of low socioeconomic status) and the presence of disease manifestations (i.e., renal or serosal involvement). These data should be considered when caring for patients with SLE.

Early clinical manifestations, disease activity and damage of systemic lupus erythematosus among two distinct US Hispanic subpopulations.

OBJECTIVES: To compare the baseline clinical manifestations, immunological features, disease activity and damage accrual in systemic lupus erythematosus (SLE) patients from two US Hispanic subgroups. METHODS: A total of 105 Hispanic SLE patients from Texas (a population of Mexican or Central American ancestry) and 81 from the island of Puerto Rico (all Puerto Ricans) participating in a longitudinal study of outcome were examined. The socio-economic/demographic, clinical and immunological variables were obtained at the time of enrollment (T(0)). Disease activity was determined with the Systemic Lupus Activity Measure (SLAM), and disease damage with the Systemic Lupus International Collaborating Clinics (SLICC) Damage Index (SDI). Disease activity was also determined at the time of diagnosis (T(D)). RESULTS: At T(0) Hispanics from Texas were younger than those from Puerto Rico (33.1 +/- 12.0 vs 37.5 +/- 11.6 yr, P = 0.0125). Both groups were similar with regard to gender distribution (92.4 vs 95.1% females) and disease duration (1.4 +/- 1.4 vs 1.7 +/- 1.3 yr). Hispanics from Texas were more likely to have serositis (60.0 vs 8.6%, P < 0.0001), renal involvement (41.0 vs 13.6%, P < 0.0001), psychosis (5.7 vs 0.0%, P = 0.0365) and thrombocytopenia (21.0 vs 3.7%, P = 0.0006). On the other hand, Hispanics from Puerto Rico were more likely to have photosensitivity (81.5 vs 41.0%, P < 0.0001), malar rash (65.4 vs 45.7%, P = 0.0074) and discoid rash (13.6 vs 2.9%, P = 0.0060). At baseline, the presence of anti-dsDNA antibodies was higher in Hispanics from Texas (69.5% vs 46.9%, P = 0.0018) while anti-Ro antibodies were more frequent in Hispanics from Puerto Rico (24.7 vs 11.4%, P = 0.0175). Mean SLAM scores at T(D) (12.9 +/- 6.4 vs 9.1 +/- 4.6, P < 0.0001) and T(0) (10.9 +/- 6.3 vs 6.6 +/- 3.8, P < 0.0001) were significantly higher in Hispanics from Texas. Similarly, mean SDI scores at T(0) were higher in Hispanics from Texas (0.67 +/- 1.08 vs 0.26 +/- 0.54, P = 0.0026). By stepwise Poisson regression, SDI scores were associated with older age, disease activity and ethnicity (Hispanics from Texas). CONCLUSIONS: Early in SLE, marked differences are observed between Hispanics from Texas and Puerto Rico. Higher disease activity, more major organ involvement, higher frequency of anti-dsDNA antibodies and more damage accrual occur in Hispanic lupus patients from Texas than in those from Puerto Rico.

Systemic lupus erythematosus in three ethnic groups. XX. Damage as a predictor of further damage.

OBJECTIVE: To examine the predictors of damage in a multiethnic cohort of systemic lupus erythematosus (SLE) patients with a specific focus on damage at baseline. PATIENTS AND METHODS: SLE patients from a multiethnic US (Hispanic, African-American and Caucasian) cohort (LUMINA: Lupus in Minority populations, Nature versus nurture) were included if they had > or =6 months of follow-up in the cohort. Damage was measured with the Systemic Lupus International Collaborating Clinics (SLICC) Damage Index (SDI). The dependent variable was the change in SDI score between study visits. Predictors were from the preceding visit. Variables known to affect damage accrual in SLE were included in the analyses. RESULTS: Three hundred and fifty-two patients (82 Hispanics, 153 African-Americans and 117 Caucasians) representing 1795 patient visits were included. Previous damage was found to be a significant predictor of subsequent damage accrual (P < 0.0001). Other variables predictive of subsequent damage accrual were disease activity (P < 0.0001), older age (P = 0.041) and use of corticosteroids (P = 0.0048). CONCLUSIONS: Once damage occurs in SLE, further damage is expected to occur. This is more likely to be the case if disease activity persists. These data have clinical implications for the management of SLE patients.

Systemic lupus erythematosus in three ethnic groups: XV. Prevalence and correlates of fibromyalgia.

The purpose of this study was to determine the prevalence and correlates of fibromyalgia (FM) in a prospective, multiethnic systemic lupus (SLE) cohort. A total of 266 SLE patients with disease duration of < or = 5 years at study entry were evaluated longitudinally for the presence of FM (per ACR criteria). Sociodemographic factors, behavioral/psychological variables, clinical features, serologic factors (autoantibodies), and self-reported functioning (MOS SF-36) were ascertained in all patients. Subjects were evaluated at study entry and annually thereafter. The prevalence of FM was then calculated, as was the prevalence of FM-like manifestations (widespread pain with at least 6, but fewer than 11/18 tender points). Variables were evaluated for association with FM or FM-like manifestations by univariate and stepwise logistic regression analyses. FM was present in 14 patients (5%; 9/92 Caucasians (C), 4/109 African Americans (AA), 1/65 Hispanics (H)) and FM/FM-like manifestations in 35 (13%; 16 C, 9 AA, 10 H). There was no difference noted between those with and without FM with respect to gender, education level, income below poverty level, disease activity or damage. By stepwise logistic regression analyses, the strongest association with both FM and FM/FM-like manifestations was a self-reported history of anxiety or affective disorder (P = 0.0237, OR = 4.6 and P = 0.0068, OR = 3.4, respectively). Caucasian ethnicity was strongly associated with FM (P = 0.0066, OR = 7.5) and African American ethnicity was negatively associated with FM/FM-like (P = 0.0204, OR = 0.3). Poorer self-reported physical functioning was associated with FM/FM-like (P = 0.0443, OR = 0.96). FM and FM-like manifestations correlate best with the presence of Caucasian ethnicity, concomitant anxiety or affective disorder, and to a lesser extent with poorer self-reported physical functioning. African American ethnicity is negatively associated with the combination of FM and FM-like manifestations. Clinical measures of disease activity, disease damage, specific organ dysfunction, sociodemographic factors and serologic features are not correlated with FM in this early SLE cohort.
