Thirteen patients with systemic lupus erythematosus and depression (Depressed-SLE), 10 Depressed-Control subjects, and 25
Healthy Control subjects completed cognitive testing and self-report questionnaires of pain, depression, and fatigue. The
Depressed-SLE group scored higher on the American College of Rheumatology Neuropsychological Battery for systemic lupus erythematosus
cognitive impairment index compared to Depressed-Control and Healthy Control subjects (p < 0.05 and p < 0.02, respectively). No correlations between cognitive impairment and pain, fatigue, or perceived cognitive failures were
observed in the Depressed-SLE participants. Moderate agreement (86.4%) was found between a comprehensive neuropsychology battery
cognitive impairment index and the ACR-SLE impairment index in the Depressed-SLE patients. Overall, the magnitude and pattern
of cognitive impairment in Depressed-SLE patients cannot be explained by depression alone. 相似文献

The study was made to evaluate bone turnover in systemic lupus erythematosus (SLE) patients undergoing long-term glucocorticoid therapy. Thirty-eight female patients with established SLE were compared with a control group consisting from 160 age-matched healthy women. Serum concentrations of proinflammatory cytokines: interleukin-1alpha, interleukin-6, tumor necrosis factor-alpha, granulocyte-macrophage colony stimulating factor (GM-CSF) and some biochemical markers of osteoporosis (osteocalcin, total and bone alkaline phosphatase, procollagen type I carboxyterminal propeptide, carboxyterminal telopeptides of type I collagen--CTx) were measured. Additionally, morning urine excretions of deoxypyridinoline and calcium/creatinin ratios were determined. The forearm densitometry (DXA) was performed in all patients. Bone mineral content (BMC) and bone mineral density (BMD) in the SLE group was not significantly different from the controls, and no relationship was found between the glucocorticoid exposure and the BMC/BMD. However, biochemical markers of bone resorption--CTx and calcium/creatinin ratio--were significantly increased in the patient group. Our results suggest that BMD/BMC is preserved in glucocorticoid-treated SLE patients despite accelerated bone turnover. 相似文献

To retrospectively evaluate safety and efficacy of long-term treatment with Cyclosporine A (CSA) in patients with systemic lupus erythematosus (SLE) poorly responsive to treatment with corticosteroids (CCS) and/or conventional disease-modifying anti-rheumatic drugs (DMARDs), SLE patients who had received CSA-based induction and maintenance regimens according to disease activity were recorded. Efficacy was assessed using the SLE Disease Activity Index (SLEDAI) and laboratory analyses. Forty SLE patients (including 18 with lupus nephritis, 11 with neurological involvement and 7 with overlap syndromes (4 Sj?gren's syndrome, 2 myasthenia gravis and 1 Beh?et's disease) were recorded. According to baseline SLEDAI, 30 patients had severe and 10 moderate SLE. Mean SLEDAI scores and relevant laboratory values significantly reduced from baseline (22?10 vs 5?6; P < 0.002) during the follow-up period (8?2 years; range 1-15). Twenty-three (57.5 percent) patients achieved excellent (improvement in the range 70-100 percent) response to treatment (10 of whom were subsequently maintained on CSA monotherapy), 14 (35 percent) had good-fair (improvement in the range 25-69 percent) response and 3 (7.5 percent) had to interrupt therapy (including CSA) for disease worsening. Mild and transient adverse events occurred in 15 (37 percent) patients, including hypertrichosis (17.5 percent), gum hypertrophy (17.5 percent) hypertension (12.5 percent), abdominal pain (7.5 percent), and dyslipidemia (5 percent), but treatment interruption was not required. Low-dose CSA together with other drugs is effective to induce, or as monotherapy to maintain, long-term (at least 2 years) remission, and is generally well tolerated in patients with moderate or severe SLE poorly responsive to CCS and/or conventional DMARDs. Furthermore, the favourable effect of CSA treatment may allow to spare more cytotoxic drugs. 相似文献

Interleukin 17 (IL-17) is a Th17 cytokine associated with inflammation, autoimmunity and defense against some bacteria, it has been implicated in many chronic autoimmune diseases including psoriasis, multiple sclerosis and systemic sclerosis. However, whether IL-17 plays a role in the pathogenesis of systemic lupus erythematosus (SLE) remains unclear. In the present study, we aimed to investigate the serum IL-17 level in patients with SLE and it’s associations with disease manifestations and activity. Fifty-seven patients with SLE and 30 healthy volunteers were recruited. Serum IL-17 levels were examined by enzyme linked immunosorbent assay (ELISA). Statistic analyzes were performed by SPSS 10.01. Results show that serum IL-17 levels were significantly elevated in SLE patients as compared with normal controls. Nevertheless, no associations of serum IL-17 level with clinical and laboratory parameters were found; no significant difference regarding serum IL-17 level between SLE patients with nephritis and those without nephritis was found; no significant difference was found between Less active SLE and More active SLE; Correlation analysis between serum IL-17 levels and SLEDAI showed no association. Taken together, our results indicate increased serum IL-17 levels in SLE patients, suggesting that this cytokine may trigger the inflammatory process in SLE. However, no associations of serum IL-17 level with disease manifestations were found. Therefore, further studies are required to confirm this preliminary data. 相似文献

Introduction
Glucocorticoid (GC) therapy is the main treatment for systemic lupus erythematosus (SLE). However, some patients are resistant to these agents. Abnormalities of glucocorticoid receptor (GR) seem to be related to steroid resistance. This study evaluated GRs in T lymphocytes and monocytes of SLE patients by flow cytometry (FCM) using a monoclonal antibody (mAb) and FITC-Dex probes. 相似文献7.

Systemic lupus erythematosus (SLE) is a disorder with a wide range of immunological abnormalities. The results of the studies undertaken in the last decade indicated that SLE pathogenesis was mainly connected with the breakdown of the activation control of B and T cells, generating humoral or cell-mediated responses against several self-antigens of affected cells. The last studies demonstrate that the role of gammadelta T lymphocytes in autoimmune diseases can be especially important. Flow cytometry techniques were used to investigate the number and percentage of TCR gammadelta T cells and their most frequent subtypes in peripheral blood of 32 patients with SLE and 16 healthy volunteers. We also correlated TCR gammadelta cells number with the level of T CD3+, T CD4+, T CD8+, and NK (CD16) cells (cytometric measurements) and SLE activity (on the basis of clinical investigations). Our studies were preliminary attempts to evaluate the role of that minor T cell subpopulation in SLE. Absolute numbers of cells expressing gammadelta TCR in most SLE blood specimens were significantly lower than in the control group (P<0.006). However, since the level of total T cell population was also decreased in the case of SLE, the mean values of the percentage gammadelta T cells of pan T lymphocytes were almost the same in both analysed populations (7.1% vs 6.3%, respectively). In contrast to Vdelta2+ and Vgamma9+ subtypes of pan gammadelta T cells, Vdelta3+ T cells number was higher in SLE patients (20 x 10 cells/microl) than in healthy control group (2 x 2 cells/microl) (P=0.001). However, we found no differences between the numbers of pan gammadelta T lymphocytes and studied their subtypes in the patients with active and inactive disease. These cell subpopulations were doubled in the treated patients with immunosuppressive agents in comparison with untreated ones; however, data were not statistically significant. Our study indicated that Vdelta3+ subtype of gammadelta T cells seems to be involved in SLE pathogenesis; however, we accept the idea that the autoimmunity does not develop from a single abnormality, but rather from a number of different events. 相似文献

Human cytomegalovirus is a common herpesvirus that is linked to autoimmunity, especially in genetically predisposed persons. The article by Hsieh and colleagues in a previous issue of Arthritis Research & Therapy suggests that a C-terminal peptide of the human cytomegalovirus protein pp65 is highly immunogenic in patients with systemic lupus erythematosus and that antibodies against this peptide cross-react with nuclear proteins and double-stranded DNA, which are highly frequent autoantibodies in systemic lupus erythematosus patients. These observations highlight the fact that immunization with one small cytomegalovirus-specific peptide results in multiple autoreactive antibodies, probably through molecular mimicry and epitope spreading, in genetically predisposed persons. 相似文献

IntroductionNeuropsychiatric systemic lupus erythematosus (NPSLE), a serious organ disorder with a variety of symptoms, has diverse therapeutic outcomes because of the variability of NPSLE manifestations. A comprehensive association study of NPSLE among clinical and immunopathogenic aspects and outcomes has not been conducted.MethodsWe analyzed the laboratory data, NPSLE symptoms, and clinical outcomes at 1 yr post-treatment and the profiles of 27 cytokines, chemokines and growth factors in cerebrospinal fluid (CSF) samples using the Bio-Plex Human 27-plex panel from 28 NPSLE patients. Univariate and multivariable competing risks regression analyses were used to determine the predictive factors of clinical response. We also tried to predict the outcome of NPSLE by the 27 cytokines/chemokines/growth factors using a weighted-voting (WV) algorithm.ResultsOf the two males and 26 females (92.9%), 16 were non-responders at 1 yr post-treatment; in the final model, the independent predictors of non-responders were longer disease durations of SLE (odds ratio [OR]: 1.490, 95% confidence interval [CI]: 1.143–2.461, p = 0.0003) and patients with more than one NPSLE symptom types (OR: 15.14, 95% CI: 1.227–452.1, p = 0.0334). The pretreatment CSF interleukin (IL)-6, IL-10, interferon-gamma (IFN-γ) and tumor necrosis factor-alpha (TNF-α) levels were significantly higher in the non-responders (p = 0.0207, p = 0.0054, p = 0.0242 and p = 0.0077, respectively). We identified six “minimum predictive markers:” IL-10, TNF-α, IL-6, IFN-γ, IL-4 and IL-13 by a WV algorithm that showed the highest accuracy (70.83%) and highest Matthews correlation coefficient (54.23%).ConclusionsWe have devised a numerical prediction scoring system that was able to separate the non-responders from responders. The patients with longer disease durations of SLE and those with more than one NPSLE symptom types had poorer outcomes. Our findings may indicate both the importance of making a diagnosis at an earlier phase for better therapeutic response and the usefulness of measuring multiple cytokines to predict NPSLE therapeutic outcomes. 相似文献

The frequency of sister-chromatid exchanges (SCEs) was investigated in peripheral lymphocytes of lupus erythematosus patients and compared with values obtained for healthy controls. Irrespective of the kind of medical treatment, an increased level of spontaneously occurring SCEs could be demonstrated in lupus patients. In addition to spontaneously occurring SCEs, mitomycin C (MMC)-induced SCEs were evaluated. No difference between patients and controls was found with respect to MMC-induced SCEs. 相似文献

Introduction
Systemic lupus erythematosus (SLE) is an autoimmune disease accompanied by a disturbed T-cell balance skewed towards effector T-cells, in particular Th17-cells. The novel cytokine interleukin-21 (IL-21) is suggested to be crucial for triggering T-cell responses towards IL-17 producing cells. Thus, we aimed to investigate the ability of T-cells to produce IL-21 and IL-17 in SLE patients. 相似文献14.

Warts were found in 25 out of 56 patients with definite or probable systemic lupus erythematosus (SLE) but in only 19 out of 160 control patients. Warts were particularly prevalent in elderly patients with SLE. The corticosteroid and antimalarial drugs used to treat SLE did not influence the frequency of warts. Wart-virus antibodies were found significantly less often in patients with SLE than in controls: antibodies were detected in 23 out of 51 patients and in 40 out of 54 controls. Ihe findings suggest that some deficiency in the immune mechanisms of patients with SLE predisposes them to develop warts. There was an inverse correlation among the patients with SLE between the occurrence of warts and rheumatoid factor activity. This suggests that rheumatoid factor may interfere with resistance to warts. 相似文献

Introduction
Dendritic cells (DCs) are capable of inducing immunity or tolerance. Previous studies have suggested plasmacytoid DCs (pDCs) are pathogenic in systemic lupus erythematosus (SLE). However, the functional characteristics of directly isolated peripheral circulating blood pDCs in SLE have not been evaluated previously. 相似文献17.

Dendritic cells are a complex group of mainly bone-marrow-derived leukocytes that play a role in autoimmune diseases. The total number of circulating dendritic cells (tDC), and their plasmacytoid dendritic cell (pDC) and myeloid dendritic cell (mDC1 and mDC2) subpopulations were assessed using flow cytometry. The number of tDC and their subsets were significantly lower in systemic lupus erythematosus patients than in the control group. The count of tDC and their subsets correlated with the number of T cells. The number of tDC and pDC subpopulation were lower in the patients with lymphopenia and leukopenia than in the patients without these symptoms. Our data suggest that fluctuations in blood dendritic cell count in systemic lupus erythematosus patients are much more significant in pDC than in mDC, what may be caused by their migration to the sites of inflammation including skin lesions. Positive correlation between dendritic cell number and TCD4+, TCD8+ and CD19+ B cells, testify of their interactions and influence on SLE pathogenesis. The association between dendritic cell number and clinical features seems to be less clear. 相似文献
