Despite their unproven efficacy and safety concerns, complementary and alternative therapies (CAT) are used by a high proportion of patients with systemic lupus erythematosus (SLE). A prospective survey of past and present CAT use was done on 192 patients (36.5 +/- 12.7 years; 106 +/- 85 months of disease duration; 94% women) with an SLE diagnosis according to ACR criteria. Quality of life [Short Form 36 (SF-36)] and cumulated damage (SLICC/ACR) were compared between CAT users and non-users. In all, 103 (53.6%; 95% CI: 46.8-60.9) patients were CAT users (median: two remedies/patient): two (1%) in the alternative mode (CAT instead of allopathic treatment); 101 (52.6%) in the complementary mode (CAT in addition to allopathic treatment). A univariate analysis showed CAT users to have higher cumulated damage (P = 0.01) levels, as well as lower physical function (P = 0.05), social function (P = 0.05) and bodily pain (P = 0.02) domain scores in the SF-36 survey. After adjustment for disease duration with a linear model, only differences in bodily pain (P = 0.04) and cumulated damage (P = 0.05) remained statistically significant. CAT use is apparently associated with lower health status in patients with SLE from Yucatan, Mexico. Because the study was cross-sectional, more research is needed to define the directionality of this association.

Patients with SLE show in a variety of neuropsychiatric symptoms, although we could not use standardized methods for evaluating and making diagnosis of the syndromes. ACR felt to develop objective and valuable tools for the diagnosis and classification of neuropsychiatric lupus, therefore, they proposed a new tentative set of nomenclatures describing neuropsychiatric lupus syndromes in accordance with 4th edition of Diagnostic and Statistical Manual of Mental Disorders provided by American Psychiatric Association. For this purpose, The Ad Hoc Committee collected and evaluated 108 case presentations of neuropsychiatric lupus from USA, Canada, and UK. Re-evaluation of the tentative nomenclatures selected 19 neuropsychiatric syndrome to facilitate and enhance clinical research. They grouped into peripheral and central nervous system lupus, and central nervous system lupus was divided into neurologic syndromes and diffuse psychiatric/ neuropsychological syndromes. Instead of organic brain syndrome, a term of acute confusional state was introduced.

Systemic lupus erythematosus (SLE) is an autoimmune disease with highly variable clinical presentation. Patients suffer from immunological abnormalities that target T-cell, B-cell and accessory cell functions. B cells are hyperactive in SLE patients. An adapter protein expressed in B cells called BANK1 (B-cell scaffold protein with ankyrin repeats) was reported in a previous study to be associated with SLE in a European population. The objective of this study was to assess the BANK1 genotype-phenotype association in an independent replication sample. We genotyped 38 single nucleotide polymorphisms (SNPs) in BANK1 on 1892 European-derived SLE patients and 2652 European-derived controls. The strongest associations with SLE and BANK1 were at rs17266594 (corrected P-value=1.97 x 10(-5), odds ratio (OR)=1.22, 95% CI 1.12-1.34) and rs10516487 (corrected P-value=2.59 x 10(-5), OR=1.22, 95% CI 1.11-1.34). Our findings suggest that the association is explained by these two SNPs, confirming previous reports that these polymorphisms contribute to the risk of developing lupus. Analysis of patient subsets enriched for hematological, immunological and renal ACR criteria or the levels of autoantibodies, such as anti-RNP A and anti-SmRNP, uncovers additional BANK1 associations. Our results suggest that BANK1 polymorphisms alter immune system development and function to increase the risk for developing lupus.

Tumour necrosis factor-alpha (TNF-alpha) plays a major role in propagating the inflammatory processes responsible for tissue damage in systemic lupus erythematosus (SLE) and is overexpressed both systemically and locally in this disease. Hence, this pilot study was carried out to assess the safety and efficacy of TNF blockade in patients with active SLE. A total of 46 individuals (27 patients with active SLE and 19 healthy control volunteers) were the subjects of this study. Nine patients with SLE were allocated to treatment arm and 18 were allocated to control arm. In addition to conventional treatment, treatment arm received infliximab infusions 3 mg/kg body weight at 0, 2, 6 weeks and then q 8 weeks for a total of 24 weeks, that is, a total of five doses. Patients were closely monitored for infection. Clinical, laboratory and treatment data were entered into a pre-designed proforma. Health status (SF-36), patient global assessment (PGA) of disease activity, disease activity scores by SLEDAI and organ damage by SLICC/ACR-DI (American College Rheumatology) were measured at baseline and end of the study. Relevant immunological studies included serum levels of TNF-alpha and soluble TNF receptors-1 (p55 srTNF-alpha) and -2 (p75 srTNF-alpha), C3 and C4 complement levels, anti-dsDNA antibody titres (IgM, IgG and IgA isotypes), anti-cardiolipin titres (IgM, IgG and IgA isotypes) and anti-beta2GPI (Glycoprotein I) antibody titres (IgM, IgG and IgA isotypes). Four patients from treatment arm dropped out due to infliximab infusion reaction and 12 patients dropped out from the control arm. The treatment group showed significantly greater improvement in Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). Improvements in several SF-36 subscales, PGA and VAS-Fatigue (Visual Analogue Scale) were also greater in the treatment group but did not achieve statistical significance. The mean levels of TNF-alpha, soluble TNF receptors-1 (p55 srTNF-alpha) and -2 (p75 srTNF-alpha) were higher in the SLE group compared with the healthy controls but did not change significantly over the study period. We did not face any safety issues with infliximab in this study. In view of improvement in several SLE parameters and good safety profile of infliximab, anti-TNF-alpha therapy is an interesting candidate approach for treating SLE.

Juvenile systemic lupus erythematosus (JSLE) and autoimmune hepatitis (AIH) are both autoimmune disorders that are rare in children and have a widespread clinical manifestation. A few case reports have shown a JSLE-AIH associated disorder. To our knowledge, this is the first study that simultaneously evaluated the prevalence of JSLE-AIH in a large JLSE and AIH population in groups of Hepatology and Rheumatology of a tertiary Paediatric University Hospital. In a 24-year period, 228 patients were diagnosed with JSLE (ACR criteria). In the same period, 252 patients were diagnosed with AIH according to the International Autoimmune Hepatitis Group. In this article, we present the demographic data, clinical features, laboratory exams and treatment of four children with both the diseases. The prevalence was 1.8% in JSLE population and was 1.6% in AIH population. The current median age was 15.5 years and three were females. In three of them, the diagnosis of AIH preceded JSLE. All of them had increased liver enzymes with a characteristic liver biopsy of AIH and responded to the combination of prednisone, azathioprine and antimalarial drugs. In conclusion, the presence of AIH-JSLE associated disorder was rarely observed. The liver biopsy could be necessary in patients with JLSE with a persistent increase of liver enzymes.

The objective was to determine the prevalence of the metabolic syndrome (MS) in patients with systemic lupus erythematosus (SLE) in Argentina, to assess the factors associated to it, and to compare the results with a control group with non-inflammatory disorders. The study included 147 patients with SLE and 119 controls. MS was defined according to criteria by the American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI) Scientific Statement. Demographic characteristics, Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and Systemic Lupus International Collaborating Clinics/ACR Damage Index (SDI) were assessed as well as administration, maximum dose and cumulative dose of prednisone and hydroxychloroquine (HCQ). MS prevalence was 28.6% (CI 95%: 21.4-36.6) in patients with SLE and 16% in controls (P = 0.0019). Patients with SLE presented higher arterial hypertension frequency compared with controls (43 vs 25%, P = 0.007). When comparing lupus patients with MS (n = 41) and without MS (n = 106), no significant differences were observed regarding duration of the disease, SLEDAI or cumulative prednisone dose. Cumulative damage was associated independently with MS (OR 1.98; P = 0.021), whereas HCQ use was found to be protective (OR 0.13; P = 0.015). Patients with lupus presented higher MS prevalence than controls with non-inflammatory disorders, and occurrence of arterial hypertension was also higher. MS was associated with cumulative damage; the use of HCQ showed to be protective against presence of MS.

Gender may produce different characteristics in the manifestation of systemic lupus erythematosus (SLE). The present study investigated the influence of gender on clinical, laboratory, autoantibodies and histopathological classes of lupus nephritis (LN). As much as 81 patients diagnosed with SLE (ACR criteria) and active nephritis, who underwent renal biopsy between 1999 and 2004, and who had frozen serum samples and clinical data available from the time of biopsy, were selected for this study. The presence of anti-P and antichromatin antibodies was measured using ELISA, and anti-dsDNA was measured using indirect immunofluorescence. All of the renal biopsies were reviewed in a blinded manner by the same expert renal pathologist. The charts were extensively reviewed for demographic and renal features obtained at the time of the biopsy. Of the 81 patients (13.6%), 11 were male SLE patients. Both male and female lupus patients were of similar age and race, and had similar durations of lupus and renal disease. The female patients had more cutaneous (95.7 vs. 45.5%, P = 0.0001) and haematological (52.9 vs. 18.2%, P = 0.04) involvements than the male SLE patients. In addition, the articular data, central nervous system analyses, serositis findings and SLEDAI scores were similar in both experimental groups. Positivity for anti-dsDNA, anti-ribosomal P and antichromatin did not differ between the two groups, and both groups showed similarly low C3 or C4 serum levels. Our analysis indicated that no histopathological class of LN was predominant in both males and females. Interestingly, the serum creatinine levels were higher in the male SLE patients compared to the female SLE group (3.16 +/- 2.49 vs. 1.99 +/- 1.54 mg/dL, P = 0.03), with an increased frequency of high creatinine (81.8 vs. 47.1%, P = 0.04) as well as renal activity index (7.6 +/- 3.5 vs. 4.8 +/- 3.5, P = 0.02). In addition, whilst the mean levels of proteinuria, cylindruria and serum albumin were markedly altered, they were comparable between both lupus men and women. Moreover, the frequencies of dialysis, renal transplantation and death were similar between the two groups. These data suggest that male patients had a more severe LN compared to women diagnosed with this renal abnormality.

Our objectives were to examine the prevalence of work disability (WD) and factors associated with job loss in systemic lupus erythematosus (SLE) in a large, multi-centered Canadian sample to determine the current prevalence of WD and identify the contribution of disease activity, damage, and co-morbidities with respect to WD in this cohort. Cross-sectional data on WD status from the 1000 Canadian Faces of Lupus database (a multi-center multi-ethnic cohort of SLE patients) along with clinical measures (number of ACR criteria ever, SLICC Damage Index, SLAM, SLEDAI, SF-36 and Charlson Co-morbidity Index scores), demographic features (age, sex, high school education, household income, marital status, disease duration, employment status) and co-morbidities (including self-reported fibromyalgia, arthralgias, depression and fatigue) were used in bivariate and logistic regression analyses. The 1137 SLE patients had a mean age of 50 years (SE 0.75) and mean disease duration was 18 years (SE 0.70); 19.09% were work disabled and 49.78% were employed. Those with WD were more likely than non-WD SLE patients to have: a higher number of ACR criteria for SLE; not completed high school; older age; single marital status; a lower household income; longer disease duration; higher SLICC Damage Index and SLAM scores; lower SF-36 PCS and SF-36 MCS scores; less vigorous activity per week; and fibromyalgia, arthralgias, fatigue and depression (p < 0.05). This contemporary rate of WD is lower than many past reports. Socio-demographic factors, co-morbidities (fibromyalgia and fatigue) and disease related factors were strongly associated with WD. We cannot determine cause and effect as the study was cross-sectional.

Our objective was to evaluate the relevance of traditional and disease-related cardiovascular risk factors and of bone mineral density for premature coronary artery calcification in young patients with systemic lupus erythematosus. Ninety-four female patients with systemic lupus erythematosus with disease durations >5 years and <45 years were consecutively selected. Cardiovascular risks (diabetes mellitus, arterial hypertension, dyslipoproteinemia, smoking, family history, body mass index, ovarian and renal insufficiency) and systemic lupus erythematosus-related risk factors (disease duration, ACR criteria, modified SLICC/ ACR, SLEDAI and treatment) were evaluated. Bone mineral density was assessed by dual X-ray absorptiometry. Coronary artery calcification was determined by computed tomography. Coronary artery calcification was identified in 12 (12.7%) patients and was associated with a higher frequency of patients with cardiovascular risks (p = 0.001), higher number of cardiovascular risks (p = 0.002), age (p = 0.025), disease duration (p = 0.011) and SLICC (p=0.011). Individual analysis of cardiovascular risks demonstrated that menopause (p = 0.036), dyslipidemia (p = 0.003) and hypertension (p = 0.006) were significantly associated with coronary artery calcification. In addition, coronary artery calcification was associated with a lower whole body bone mineral density (p = 0.013). Multiple logistic regression analysis using cardiovascular risks, age, disease duration, SLICC and whole body bone mineral density revealed that only disease duration (p = 0.038) and whole body bone mineral density (p = 0.021) remained significant for coronary artery calcification. In conclusion, we found that disease duration and decreased bone mineral density are independent predictors for premature coronary calcification in young women with systemic lupus erythematosus, suggesting a common underlying mechanism.

The objective of this study was to determine the frequency of Metabolic Syndrome (MetS) in patients with SLE and to analyze the association of MetS with traditional risk factors for CHD and lupus characteristics. In this cross-sectional study the frequency of MetS was determined according to the National Cholesterol Education Program Adult Treatment Panel III in patients with SLE. The association of MetS with the traditional risk factors for CHD not included in the syndrome definition, and with lupus characteristics was examined. The mean age (sd) of the 162 females patients was 38.8(11.2) years. The frequency of MetS was 32.1%. Abdominal obesity and hypertension were the two most common components of the syndrome (86.5% each) followed by low levels of HDL-cholesterol (84.6%), hypertriglyceridemia (69.2%) and hyperglycemia (15.4%). MetS was significantly associated with older age, family history of CHD, obesity, postmenopausal status, LDL-c > or =100mg/dl, and higher Framingham risk score. Lupus characteristics associated with MetS were history of nephrotic proteinuria during follow-up and current cyclophosphamide use, higher modified SLEDAI-2k, higher damage index score (SLICC/ACR), and older age at lupus diagnosis. In the logistic regression analysis, obesity, LDL-c > or =100mg/dl, older age at lupus diagnosis, higher damage index and nephrotic proteinuria were independently associated with MetS. We conclude that MetS diagnosis was frequent in patients with lupus. The syndrome was associated not only with traditional risk factors for CHD, confirming the clustering of those risk factors, but also with lupus characteristics. Some of those factors, especially LDL-c > or =100mg/dl and age at lupus diagnosis, have been associated with atherosclerosis in lupus patients. Lupus (2010) 19, 803-809.
