In this study, we determined the adiponectin expression in the serum and lesional skin of patients with scleroderma (SSc). Serum adiponectin concentrations were measured in 32 patients with SSc, 10 patients with SLE, 12 patients with dermatomyositis patients and 13 healthy subjects with specific enzyme-linked immunosorbent assays. Adiponectin mRNA was determined in skin tissues of five patients with diffuse cutaneous SSc (dcSSc), seven patients with limited cutaneous SSc (lcSSc) and seven healthy subjects with real-time polymerase chain reaction. There was a significant reduction in serum adiponectin levels in patients with dcSSc. SSc patients with decreased serum adiponectin levels had higher total skin thickness score and higher incidence of pulmonary fibrosis. Adiponectin mRNA levels in skin tissues from patients with dcSSc were also reduced. Serum adiponectin levels may be a useful biomarker for fibrotic condition in patients with SSc. Clarifying the role of adiponectin in collagen diseases may lead to further understanding of the pathogenesis and new therapeutic approach. 相似文献

Undifferentiated connective tissue disease (UCTD, also named UCT syndrome, latent lupus or incomplete lupus) is regarded as an autoimmune disorder in which signs and symptoms are widely variable and evocative for connectivitis but not sufficiently evolved to fulfil any of the accepted classification criteria for the defined connective tissue diseases. In this paper we describe the case of a 47-year-old woman affected by UCTD according to the preliminary classification criteria supplied by Mosca et al. in 1999. 相似文献

Bullous systemic lupus erythematosus (BSLE) is a rare subepidermal blistering disorder characterized by an acute vesiculobullous eruption in a subset of individuals with systemic lupus erythematosus. BSLE most commonly affects young women and only rarely affects children. Herein we report a rare case of BSLE in a 6‐year‐old boy. 相似文献

BACKGROUND: Statins have been increasingly associated with drug-induced autoimmune reactions, including lupus erythematosus. OBJECTIVE: To identify and determine the clinical and biological characteristics of statin-induced autoimmune reactions. MATERIAL AND METHODS: The MEDLINE database (1966 to September 2005) was used to identify all reported cases of statin-induced autoimmune diseases. The keywords used were statins, 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, adverse effects, autoimmune disease, lupus erythematosus, dermatomyositis and polymyositis. RESULTS: Twenty-eight cases of statin-induced autoimmune diseases have been published so far. Systemic lupus erythematosus was reported in 10 cases, subacute cutaneous lupus erythematosus in three cases, dermatomyositis and polymyositis in 14 cases and lichen planus pemphigoides in one case. Autoimmune hepatitis was observed in two patients with systemic lupus erythematosus. The mean time of exposure before disease onset was 12.8+/-18 months; range 1 month-6 years. Systemic immunosuppressive therapy was required in the majority of cases. In many patients, antinuclear antibodies were still positive many months after clinical recovery. A lethal outcome has been recorded in two patients despite aggressive immunosuppressive therapy. CONCLUSION: Long-term exposure to statins may be associated with drug-induced lupus erythematosus and other autoimmune disorders. Fatal cases have been reported despite early drug discontinuation and aggressive systemic immunosuppressive therapy. 相似文献

Inhibition of transforming growth factor (TGF)‐β1 signalling may be one of the most reliable approaches to treat skin fibrosis of scleroderma. Although there have been many basic researches of TGF‐β blockade reagents, few of them were proved to have inhibitory effects on fibrosis both in vitro and in vivo. In this study, we randomly chose four commercially available low molecular weight compounds (Repsox, LY2109761, LY364947 and K02288) from TGF‐β1 inhibitor library, and compared their antifibrotic effects in vitro and in vivo. We demonstrated that Repsox has the most potent inhibitory effects on TGF‐β‐induced expression of CTGF and collagen of cultured normal dermal fibroblasts in vitro and their constitutive overexpression of scleroderma fibroblast in vitro. In addition, Repsox could attenuate skin fibrosis by bleomycin in vivo, via the downregulation of CTGF or collagen. Our results may facilitate clinical trial of Repsox against fibrotic diseases in future. 相似文献

Human milk fat globule‐EGF factor 8 (MFG‐E8), also known as lactadherin, is a secreted glycoprotein that plays essential roles in the clearance of apoptotic cells and angiogenesis. It has been reported that serum MFG‐E8 levels are higher in systemic lupus erythematosus (SLE) patients compared with in healthy controls; however, a previous study reported no correlation between serum MFG‐E8 levels and SLE disease activity. The objective of this study was to assess serum MFG‐E8 levels and their clinical associations in patients with SLE. Serum MFG‐E8 levels in 49 Japanese patients with SLE, eight with cutaneous LE, and 28 healthy controls were examined. Serum MFG‐E8 levels in SLE patients were significantly higher than those in cutaneous LE patients and healthy individuals. In addition, serum MFG‐E8 levels were positively correlated with the SLE Disease Activity Index score, which reflects the disease activity of SLE. Notably, the frequency of the presence of high‐intensity cerebral lesions on MRI in the SLE patients with elevated serum MFG‐E8 levels was significantly higher than that in SLE patients with normal serum MFG‐E8 levels. These findings suggest that elevated serum MFG‐E8 levels may be associated with cerebrovascular diseases or neuropsychiatric SLE in patients with SLE, and that the measurement of serum MFG‐E8 levels in SLE patients is useful for risk stratification of cerebrovascular disease or cerebrovascular disease‐related neuropsychiatric SLE. 相似文献

Matrix metalloproteinase‐13 (MMP‐13), a member of the collagenase family, has been implicated in the pathogenesis of connective tissue diseases characterized by extracellular matrix remodeling. Since serum MMP‐13 levels reflect disease severity of systemic sclerosis and localized scleroderma, we evaluated the clinical significance of serum MMP‐13 levels in eosinophilic fasciitis (EF). All the EF patients had serum MMP‐13 levels lower than the mean – 2SD of healthy controls. Serum MMP‐13 levels were also significantly decreased in EF patients compared with diffuse cutaneous systemic sclerosis, limited cutaneous systemic sclerosis, and generalized morphea patients. Although serum MMP‐13 levels did not reflect any clinical and serological features of EF, these results indicate that MMP‐13 may be involved in the development of this disease. 相似文献

Ultra violet radiation (UVR) is an important feature for the development or aggravation of several dermatologic diseases. In autoimmune skin diseases it has been suggested as an important cofactor in autoimmune bullous skin diseases and more importantly cutaneous lupus erythematosus (CLE). The pathophysiological role of UVR in CLE is a result of several effects which are triggered by UVR. In detail UVR induces apoptosis of keratinocytes and an abnormal local immune response which triggers inflammation in the skin. These findings result in the clinical approach of a stringent UVR protection in affected patients. Currently UVR protection is advised to patients as a supportive measure but cannot be prescribed to patients as these products are not licensed. Well-defined prospective placebo controlled studies regarding UVR protection are missing. 相似文献

An understanding of the differences in clinical manifestations and laboratory abnormalities between subtypes of cutaneous lupus erythematosus (CLE) is still lacking. The purpose of this study was to analyze demographic, clinical and histological features of CLE according to three main presentation subsets: acute (ACLE), subacute (SCLE) and chronic (CCLE). A 10‐year retrospective analysis was performed on data from patients who were diagnosed with CLE between March 2005 and September 2015 in a Korean tertiary referral dermatology clinic. We compared demographic data and clinical and histological findings between three different CLE groups. An overall sample of 220 patients with CLE consisted of 67 patients with ACLE, 25 patients with SCLE and 135 patients with CCLE. Patients with CCLE regardless of systemic lupus erythematosus (SLE) presence had lower prevalence of anemia, urinary abnormalities and elevated erythrocyte sedimentation rate. Furthermore, CCLE patients who only had skin lesions showed lower female predominance, lower extracutaneous manifestation, fewer laboratory and immunological abnormalities including low antinuclear antibody titers and the lowest positivity for C3, C4 and anti‐dsDNA, anti‐Ro, anti‐Sm and anti‐RNP antibodies, and more prominent perieccrine inflammation and dermal fibrosis in histological findings. Considering distinct cutaneous manifestations of LE, a comprehensive awareness of each CLE subtype is important for achieving a favorable prognosis through appropriate diagnosis and management. This study provides comparative clinical and histological profiles of patients with different CLE subtypes in Korea. 相似文献

BACKGROUND: The therapy of cutaneous lupus erythematosus (CLE) is often challenging, especially in patients resistant to topical treatment and established first-line systemic drugs such as antimalarials. Systemic corticosteroids are effective, but their use is limited due to well-known side-effects, especially in long-term treatment. In recent years several other immunosuppressive agents have been successfully applied in CLE. However, there are no large studies or explicit guidelines on the use of these drugs in CLE. OBJECTIVES: To perform a retrospective investigation of the efficacy of low-dose methotrexate (MTX) in the treatment of CLE. METHODS: One hundred and thirty-nine patients with CLE were seen at our department between 2001 and 2003, of whom 43 patients required low-dose MTX. All had histologically confirmed CLE lesions. Clinical data including disease activity, additional treatment, laboratory parameters and side-effects were recorded carefully at the time of presentation. Statistical analyses were performed by paired nonparametric Wilcoxon test and Student's t-test using SPSS 11 software. RESULTS: MTX led to a highly significant (P < 0.01) decline in disease activity. An improvement of the cutaneous lesions was recorded in nearly all patients treated with MTX (42 of 43; 98%). Severe side-effects necessitating discontinuation of MTX treatment were recorded in seven patients (16%), which quickly resolved when MTX was discontinued. Life-threatening complications were not observed. Intravenous application was tolerated better than oral administration. Interestingly, we observed a significant increase in circulating lymphocyte numbers in patients with lymphopenia (< 1.0 x 10(9) cells L(-1)) prior to MTX treatment. CONCLUSIONS: Our study supports earlier findings reporting the efficacy of low-dose MTX in CLE lesions, particularly in recalcitrant clinical courses. MTX treatment appears to be safe if patients are carefully selected and monitored, with particular attention to side-effects and contraindications. 相似文献

Drug‐induced lupus erythematosus (DILE) is a less severe variant of systemic lupus erythematosus (SLE) that generally resolves within weeks or months after the withdrawal of the implicated drug. DILE is unusual during childhood, with the most frequent age of presentation being at 50–70 years of age. Among different drugs, most commonly procainamide and hydralazine have been implicated as a cause of DILE. However carbamazepine (CBZ) is considered a low‐risk drug and very few cases have been reported in children. We describe the case of CBZ‐induced SLE in a 9‐year‐old girl following 3 years of CBZ therapy. This case report shows that drug‐induced SLE is an important side‐effect to be considered, even after long‐term treatment with CBZ, and also during childhood. 相似文献

Interleukin (IL)‐34 is a hematopoietic cytokine promoting proliferation and differentiation of macrophages. Because abnormal activation of macrophages is involved in the development of systemic sclerosis (SSc), we investigated serum IL‐34 levels in patients with SSc. Serum IL‐34 levels were significantly increased in diffuse cutaneous SSc compared with limited cutaneous SSc and healthy controls, while there were no significant differences between limited cutaneous SSc and healthy controls. In addition, SSc patients with increased serum IL‐34 levels more often had interstitial lung disease (ILD) than those with normal levels. Moreover, in SSc patients, serum IL‐34 levels negatively correlated with the percentage of predicted vital capacity, while they positively correlated with ground‐glass opacity score and fibrotic score on chest computed tomography. Collectively, increased serum IL‐34 levels were associated with greater frequency and severity of ILD in SSc patients. Serum IL‐34 levels may be a useful serological marker for SSc‐associated ILD. 相似文献

The Japanese Dermatological Association prepared guidelines focused on the treatment of skin ulcers associated with connective tissue disease/vasculitis practical in clinical settings of dermatological care. Skin ulcers associated with connective tissue diseases or vasculitis occur on the background of a wide variety of diseases including, typically, systemic sclerosis but also systemic lupus erythematosus (SLE), dermatomyositis, rheumatoid arthritis (RA), various vasculitides and antiphospholipid antibody syndrome (APS). Therefore, in preparing the present guidelines, we considered diagnostic/therapeutic approaches appropriate for each of these disorders to be necessary and developed algorithms and clinical questions for systemic sclerosis, SLE, dermatomyositis, RA, vasculitis and APS. 相似文献

Background Lupus erythematosus tumidus (LET) is a rare disease which was first described in 1909 but has not always been considered as a separate entity of cutaneous lupus erythematosus (CLE) in the international literature.
Objectives To compare characteristic features of different subtypes of CLE and to analyse whether LET can be distinguished as a separate entity in the classification system of the disease.
Methods The study involved 44 patients with CLE, including 24 patients with LET, 12 with discoid lupus erythematosus (DLE) and eight with subacute CLE (SCLE), from two centres in Germany. A core set questionnaire and an SPSS database were designed to enable a consistent statistical analysis.
Results Location of skin lesions did not differ significantly between the CLE subtypes; however, the activity score was significantly lower in LET than in DLE ( P < 0·01), and the damage score was significantly lower in LET than in SCLE ( P < 0·01) and DLE ( P < 0·01). Photosensitivity and antinuclear antibodies were confirmed to be different in LET compared with SCLE and DLE but without statistical significance. Moreover, histological analysis of skin biopsy specimens showed that abundant mucin deposition is significantly more present in LET compared with SCLE ( P < 0·01) and DLE ( P < 0·01) while prominent interface dermatitis and alteration of hair follicles were absent in LET.
Conclusions Several significant differences were found between LET and other subtypes of CLE with regard to clinical, histological and laboratory parameters. These data strongly indicate that LET should be defined as a separate entity in the classification of CLE. 相似文献

Previous studies have demonstrated that B cells play critical roles in autoimmune disorders including systemic sclerosis (SSc) and systemic lupus erythematosus (SLE). However, the effectiveness of rituximab (RTX), a chimeric anti‐CD20 antibody, for SSc‐associated interstitial lung disease (ILD) or SLE disease activity remains controversial. We herein report an SSc patient with severely progressed ILD and concomitant SLE treated by two cycles of RTX at baseline and half a year later. This treatment improved ILD and SLE activities, along with reduction of dermal sclerosis and serum anti‐topoisomerase I antibody levels. In addition, our detailed time‐course data indicate that half a year may be appropriate as an interval between each cycle of RTX therapy aimed at SSc‐associated ILD or SLE. Overall, the current report could pave the way to establish RTX as a disease‐modifying drug for patients with SSc and/or SLE showing resistance to other already approved medications. 相似文献
