Management must be multidisciplinary, to avoid complications that are often serious. We report the case of a 20-year-old patient with no known cardiovascular history who consults for dyspnea, and retrosternal pain associated with a dry cough. On physical examination, she had tachycardia, swelling of the lower limbs, jugular turgidity, and deafening heart sounds. Cardiac Doppler ultrasound shows dilation of the right cavities, paradoxical septum and significant pulmonary arterial hypertension, pericardial effusion of medium abundance. On oral examination, it presents an ulceration of the lips, dermatological examination finds scattered hypo chromic spots in the body, more accentuated in the face. Before the hypo chromic dermatosis, a dermatological consultation was carried out with an autoimmune assessment that came back positive for systemic scleroderma.展开更多

Methods: ADSCs were isolated from pathogen-free female C57BL/6 mice and LS was induced in wild type (WT) C57BL/6 mice via daily injection of bleomycin (0.1 mL x 300 mu g/mL) for 4 weeks; then the ADSCs were subcutaneously injected into the dorsal area in the model treatment group, and 100 mu L of phosphate buffered saline (PBS) solution was injected into the same site in the model control group. Green fluorescent protein (GFP) was used to track the cells using an in vivo imaging system on days 7, 14, 21 and 28 after transplantation. All mice were sacrificed and histologic analyses were performed after 4 weeks, and the skin thickness, collagen deposition and the total content of hydroxyproline were evaluated. Additionally, immunohistochemistry were performed to compare the tissue expression and distribution of TGF-beta 1 and VEGF between the ADSCs treatment group and the treatment control group. Results: WT C57BL/6 LS mouse model were successfully established and GFP in vivo fluorescence imaging showed that the translated ADSCs survived at the local for at least 4 weeks. Compared with the control group, the ADSCs treatment group significantly attenuated bleomycin-induced dermal fibrosis, reduced the skin thickness and the total content of hydroxyproline (P<0.05). The ADSCs treatment group displayed significantly lower levels of TGF-beta 1 and higher levels of VEGF than the control group (P<0.05). Conclusions: ADSCs may provide a feasible and practical treatment for autoimmune diseases such as LS and ameliorate dermal fibrosis.展开更多

Monolayer from human fibroblasts was cultured in vitro, and a mouse model of scleroderma was established by subcutaneous injection of 100 μL of 400 μg/mL bleomycin into the back of BALB/c mice for 4 weeks. The mouse models and human fibroblasts were divided into UVA1- exposed (100, 60 and 20 J/cm2) and UVA-unexposed groups. At 0, 24 and 48 h after exposure, cell proliferation and levels of hydroxyproline and collagen were detected. UVA1 irradiation was performed 3 times weekly for 10 weeks, and the pathological changes of skin tissues, skin thickness and collagen level were observed after phototherapy. Cell proliferation and the levels of hydroxyproline and collagen were inhibited after phototherapy, and there was a significant difference between the UVAl-exposed cells and UVAl-unexposed cells (P 〈 0.001). In addition, UVA1 phototherapy improved dermal sclerosis and softened the skin, and there were significant differences between the high-dose UVA1 group and the model group, and the negative group (P 〈 0.05). It is concluded that UVA1 radiation can reduce cell proliferation, and decrease hydroxyproline and collagen levels in a dose-dependent manner in vitro. High-dose UVA1 phototherapy has marked therapeutic effect on scleroderma in the mouse model. Decreased collagen level may be related to the reduced number and activity of cells, as well as inhibition of collagen synthesis.展开更多

Methods: Thirty-three patients were treated with XFZY and Vit B 6, with 15 cases taking orally prednisone acetate and 20 healthy volunteers as the control. Their level of soluble interleukin-2 receptor (sIL-2R) and tumor necrosis factor-α (TNF-α) in the patients with LSD before and after treatment were observed. Results: The level of sIL-2R and TNF-α in the serum from the patients with LSD were higher than those of healthy volunteers ( P <0.01). After treatment with Vit B 6 and XFZY, the level of sIL-2R and TNF-α from the patients with LSD decreased significantly ( P <0.01), but there were no difference between the group taking Vit B 6 plus XFZY and the group given prednisone. Conclusion: The activating blood circulation to remove stasis approach in treating LSD with integrative Chinese and Western drugs got better results, and metabolic disorder of tryptophan might be correlated with the etiology of LSD.展开更多

Methods: 1145 SSc patients had ANA and ENA analyzed by indirect immunofluorescence on HEp-2 substrate at a screening serum dilution of 1/160. Most ENA antibodies [Sm. U1-RNP, Ro52, SS-A/Ro60, topoisomeraseI (Topo1), SS-B/La, chromatin, ribosomal P and Jo1] were measured by laser bead immunoassay;and RNA polymerase III (RNAP) by ELISA. Results: ANA was positive in 95% (same in lcSSc, and dcSSc). Centromere pattern was present in 34%, speckled 22%, nucleolar 18%, homogeneous and speckled (H&S) 16%, multiple nuclear dots 6%. Anti-centromere Ab (ACA) occurred in 46% of lcSSc and 11% of dcSSc (P = 0.0001). ENAs that differed between lcSSc and dcSSc subsets were Topo1 (OR 2.4, P = 0.0001) and RNAP (OR 5.6, P 0.0001) more common in dcSSc. Overall, 15% had positive Topo1;usually with a H&S pattern (67%);Topo1 was associated with ILD on CXR (OR 2.3;95% CI 1.5 - 3.5) and HRCT (OR 3.8;95% CI 1.8 - 8.2). RNAP occurred in 18.5% (35.4% in dcSSc vs. 8.9% in lcSSc). Scleroderma renal crisis (SRC) was 13 times more likely if RNAP positive;P = 0.0001. ACA was only weakly associated with sPAP > 50 mmHg (OR 1.8;95%CI 1.1 - 3.0). Conclusion: ANA homogeneous pattern alone is rare in SSc;ACA was significantly more common in lcSSc. Many ENAs are equal in lcSSc and dcSSc except RNAP and Topo1. RNAP has the highest OR of SRC. Topo1 is less strongly associated with ILD. Abstract word count: 249, Body word count 1246, Figures 2, Tables 2. Key Messages: 1) 95% of SSc has a positive ANA and ANA patterns in SSc include centromere, nucleolar, and homogeneous and speckled together;2) Most ENAs are equal in both dcSSc and lcSSc except anti RNA polymerase III and topoisomerase I;3) RNA polymerase III has the highest association (odds ratio) with scleroderma renal crisis, topoisomerase I is associated with interstitial lung disease;whereas anticentromere was not associated with elevated pulmonary arterial pressures on echocardiogram.展开更多

This study evaluated the radiological imaging in patients with digital gangrene associated with collagen disease and compared the images with those of PAD based on the results of laboratory and histopathological examinations. Methods: Angiography, MR angiography and/or CT angiography were performed on 6 patients with refractory gangrene or extensive ulcers accompanied by scleroderma-spectrum disorders;3 with diffuse systemic sclerosis, 1 with limited systemic sclerosis, 1 with overlap syndrome and 1 with Sj?gren’s syndrome. Results: Although the vascular alterations in collagen diseases were similar to those in PAD, the abnormal image findings (occlusion or stenosis of the arteries with smooth vessel walls) found in collagen diseases did not include atheromatous plaque, which are worm-like vessels that are characteristic of those observed in PAD. Conclusions: Some cases of digital gangrene seen in collagen diseases show similar vascular imaging patterns to those of PAD and comprehensive examinations including arterial imaging can be useful for the diagnosis of these unrecognized vascular changes other than vasculitis or digital thrombosis.展开更多

In a randomized controlled study from our research group it was shown that treatment with 2 courses of RTX leads to a significant improvement of lung function at 1 year compared to baseline. All relevant studies have so far reported clinical and/or histologic improvement of skin fibrosis something that adds further evidence in favor of a disease modifying role of RTX in SSc. It is more than obvious that novel therapies for SSc-associated lung disease are needed. A large scale, randomized, controlled study assessing the efficacy of RTX in SSc associated interstitial lung disease is warranted. If RTX turns out to be effective it would be a major therapeutic advance in SSc since it can be administered on a long term basis due to its acceptable safety profile.展开更多

Background: Prior studies have showed an increased risk of cardiovascular disease among patients with chronic inflammatory disorders, with chronic inflammation leading to atherosclerosis believed to be the culprit. Systemic sclerosis (SSc) is a chronic inflammatory disease characterized by diffuse fibrosis of the skin and internal organs. Previous studies have suggested a possible link between systemic sclerosis and macrovascular complications such as stroke. Methods: This is a retrospective chart review of patients treated within the University of Pennsylvania Health System from October 2015 to April 2019 with a diagnosis of SSc. Using ICD10 codes, we identified a cohort of SSc patients who suffered a stroke. Information regarding demographics and stroke risk factors were gathered from the charts of patients with a diagnosis of both SSc plus stroke and compared to a control group of randomly selected patients with SSc who never suffered a stroke. Continuous variables were conveyed using a mean plus a standard deviation. A two-sample t-test was used to compare the two groups of patients. Qualitative variables were compared using a two-tailed Fisher’s exact test. Results: Based on a large cohort of SSc patients (n = 2080) followed between October 2015 and April 2019, we identified 36 SSc patients who developed a subsequent stroke (1.7% of cohort). When looking at risk factors for stroke in SSc patients, we identified hypertension and atrial fibrillation to be associated with the diagnosis of stroke in such patients. Specifically, 28 of the 36 patients with both SSc and stroke also had a diagnosis of hypertension while in the control group, only 17 of 36 patients had hypertension. Atrial fibrillation was seen in 9 of 36 patients with both SSc and CVA while it was seen in only 2 of 36 patients in the control group. Conclusions: This case control study demonstrated that the presence of hypertension and atrial fibrillation had a statistically significant association with the diagnosis of CVA in patients with SSc.展开更多

Blood tests revealed sudden drop of haemoglobin and an urgent gastroscopy revealed gastric antral vascular ectasia (GAVE) or “watermelon stomach”. GAVE is a rare but well recognised cause of acute bleeding in systemic scleroderma patients and should be kept as a differential diagnosis in the work up of anaemia in these patients.展开更多

It is hypothesized that intense epithelial proliferation that is accompanied by the .brotic process increases the occurrence of carcinomatous changes. We report the case of a pa-tient who presented with 3-year history of Raynaud's phenomenon, gradual tightening of the skin which was ignored by the patient and her family members, and a 2-week history of severe respiratory dis-tress with left shoulder and upper back pain followed by the develop-ment of paraparesis. After a series of examinations, the patient was diagnosed with scleroderma and simultaneously with bronchogenic carcinoma and multiple distant metastases.展开更多

We present case of primary cardiac involvement and the diagnostic role of cardiac MRI. Cardiovascular magnetic resonance imaging (MRI) is an accurate, quantitative method for the non-invasive assessment of myocardial perfusion. The presence of clinically apparent myocardial involvement in scleroderma portends a very poor prognosis. One study of US veterans found that clinical cardiac disease in scleroderma was associated with a 70% mortality rate at five years. Management of heart failure and conduction system abnormalities in scleroderma is similar to other cardiac disease. It includes afterload reduction, beta-blockade, defibrillator placement, etc. Patients with reduced cardiac function and normal coronary arteries may benefit from increased immune suppresion.展开更多

Methods: 12 mice model of scleroderma was established by the injection of Bleomycin. The level of CTGF and COL-I were detected by immunohistochemical method. The relationship was analyzed between CTGF and COL-I level. As control group, 12 healthy mice were selected. Results: The levels of CTGF and COL-I in sclerotic models were higher than in normal controls (P 〈 0.05). It was found that there was a correlation between the level of CTGF and COL-I. Conclusion: CTGF and COL-I played an important role in the hardening process of the skin lesions of the mice model, which may be involved in the pathogenesis of scleroderma.展开更多

Methodology: We conducted a retrospective and descriptive study over a period of 10 years (September 15, 2008 to April 15, 2019) on the files of patients hospitalized for systemic scleroderma in the rheumatology unit of the UTH of Cocody. We used the classification criteria of the American Society of Rheumatology (1980) to retain the diagnosis. Results: Nineteen patients’ files had been collected, representing a hospital frequency of 0.32%. The average age was 37.25 ± 13.82 years old. There were 15 women and 4 men. The average consultation time was 26.44 months. The mode of revelation of the disease was mostly cutaneous and articular. All patients had cutaneous sclerosis (average Rodnan score = 27.63/11.61 (min = 4, max = 49).) Scleroderma was diffuse in 70.59% of cases;a Raynaud’s phenomenon was seen in 47.37%. The main clinical manifestations were: cutaneous (100%), articular (89.47%), pulmonary (57.89%) and digestive (63.16%). No renal damage was found. Pulmonary fibrosis (5 cases), pulmonary arterial hypertension (3 cases) and pericardial effusion (2 cases) were sometimes founded in explorations. The positivity of antinuclear antibodies (ANA) was seen in 72% of patients and anti scl70 antibodies in 42.85%. The treatment included corticosteroids and immunosuppressants, respectively used in 84.2% and 63.16% of cases. The outcome was marked by 5 cases of death attributed to respiratory distress. Conclusion: Systemic scleroderma seems to be a very rare condition in Ivorian rheumatology milieu. The main systemic manifestations were digestive and pulmonary. Treatment was very often symptomatic sometimes associated with D-penicillamine.展开更多

The aim of this study was to describe the epidemiological, clinical, therapeutic and evolutionary aspects of scleroderma at the Department of Dermatology-Venerology at Donka National Hospital. Methods: This was a descriptive cross-sectional study with a retrospective collection of data for a period of 11 years, from January 1, 2000, to December 31, 2010, covering all inpatient records of Scleroderma in the service. Results: We collected 17 cases of scleroderma out of 3289, a frequency of 0.04%. The average age of patients was 33.33 years with extremes of 10 and 60 years. A female predominance was noted with a sex ratio M/F of 0.13. Cutaneous induration was the main symptom associated with the phenomenon of Raynaud, and disorders of pigmentation. The extra-skin manifestations were mainly dominated by gastrointestinal involvement (32%), pulmonary involvement (24%), cardiac (20%), articular (20%) and renal (12%) involvement. The systemic form was the most common (99.45%). Corticotherapy was the most prescribed treatment (24.59%). Clinical improvement was noted in (93.2%) of the cases. Conclusion: Scleroderma, although rare, deserves special attention at all levels for early diagnosis.展开更多

Autoimmune diseases can develop in people living with HIV, most in a context of good immunological control (vasculitis, anti-phospholipid syndrome). Since the advent of antiretroviral therapy, an increasing number of autoimmune connective tissue diseases such as systemic lupus erythematosus, dermatomyositis, and syndromes of Sj?gren and scleroderma have been reported. Purpose: To describe this association’s not very common scleroderma and HIV infection. Observation: We report the case of a 56-year-old lady admitted into the service for functional impotence that would have been evolving for a week. Prior to her hospitalization, she presented edemas of the lower limbs associated with anesthesia of the lower limbs for 5 months. The painting is accompanied by a productive cough and an intermittent fever. At the physical examination a weight loss (BMI = 13.74 Kg/m2), fever (38.7°C): Oral candidiasis, lower lip ulceration, perlicking, undernutrition folds, sclerodactyly and homogeneous hepatomegaly was noted. The diagnosis of immunosuppression to HIV Stage 3 with TB co-morbidity and positive hepatitis B Serology was retained while diffuse Scleroderma was selected from the ACR/EULAR criteria of 2012 with a score of 10 (sclerodactyly = 4 point;Raynaud’s phenomenon = 3 point and Ac Anti Scl 70 positive = 3 point). Conclusion: These associations of chronic pathology must be described to improve the future treatment of our patients.展开更多

文摘BACKGROUND Eosinophilic fasciitis(EF)is a rare connective tissue disease that can cause swelling and sclerosis of the extremities,and special attention is needed to differentiate EF from systemic sclerosis.Misdiagnosis or omission markedly delays treatment of EF,and severe skin sclerosis in advanced stages can cause joint contracture and tendon retraction,worsening the patient's prognosis and quality of life.CASE SUMMARY We report a case of EF in a young woman diagnosed by tissue biopsy,confirming the difficulty of differential diagnosis with scleroderma.CONCLUSION Focusing on skin manifestations,completing tissue biopsy and radiography can help diagnose EF effectively.Clinicians should enhance their understanding of the differences between EF and scleroderma,and early diagnosis and standardized treatment can improve the prognosis of patients with EF.
文摘Scleroderma (or systemic sclerosis) is a disease characterized by abnormalities in the functioning of small blood vessels and the immune system, ultimately leading to inflammation and excessive fibrosis of the skin and various organs, including the heart. Management must be multidisciplinary, to avoid complications that are often serious. We report the case of a 20-year-old patient with no known cardiovascular history who consults for dyspnea, and retrosternal pain associated with a dry cough. On physical examination, she had tachycardia, swelling of the lower limbs, jugular turgidity, and deafening heart sounds. Cardiac Doppler ultrasound shows dilation of the right cavities, paradoxical septum and significant pulmonary arterial hypertension, pericardial effusion of medium abundance. On oral examination, it presents an ulceration of the lips, dermatological examination finds scattered hypo chromic spots in the body, more accentuated in the face. Before the hypo chromic dermatosis, a dermatological consultation was carried out with an autoimmune assessment that came back positive for systemic scleroderma.

文摘Background:Juvenile Localized Scleroderma(JLS)is a rare pediatric rheumatic disease characterized by inflammation and skin sclerosis.The side effect of consensus-recommended medications and the risk of disability posed challenges to the JLS treatment.We intend to demonstrate the potential of traditional Chinese medicine in treating JLS with skin ulcers and reducing the dose of glucocorticoid.Method:Here we report a case of a 13-year-old male with JLS who took oral methotrexate tablets of 10 mg/week and methylprednisolone of 6 mg/day for over six months without significant effect and suffered from skin ulcers on the dorsal feet one month after drug cessation.Subsequently,the patient was treated with integrated traditional Chinese and Western medicine of low-dose glucocorticosteroid,adjusted Shenqi Huoxue formula and Jinshe Xiaoyan formula,etc.Results:After integrated treatment,the patient’s dorsal feet ulcers healed and the skin sclerosis and hyperpigmentation improved significantly.Conclusions:This case report suggests that integrated traditional Chinese and Western medicine can be used as an effective treatment for JLS.
文摘Background:Systemic sclerosis is a connective tissue disease characterized by fibrosis of the skin and organs,marked changes in microvascular structure,cellular and humoral immune disorders.Renal involvement is more frequent and mainly characterized by moderate proteinuria,elevated serum creatinine levels,and hypertension.The most common kidney involvement in SSc is scleroderma renal crisis(SRC)that is fatal without prompt intervention.Case report:A 52-year-old Caucasian male with known diffuse cutaneous systemic sclerosis was hospitalized with communityacquired pneumonia.On the fifth day after appropriate antibiotic therapy and 60 mg/day methylprednisolone,decreased urine output,arterial hypertension,decreased renal function and pulmonary edema developed.The patient was diagnosed with a scleroderma renal crisis.Emergency hemodialysis was applied to the patient,and captopril 6×25 mg/day and nifedipine 2*60 mg/day treatment were given.He received a routine hemodialysis program for about three months.The hemodialysis program was terminated when the patient’s urine quality and quantity increased.Conclusions:SRC,characterized by malignant hypertension,azotemia,microangiopathic hemolytic anemia,and kidney failure,is one of the most important complications of systemic sclerosis with a poor prognosis without prompt intervention.Steroid use is one of the important risk factors that precipitate SRC development.With angiotensin-converting enzyme inhibitors,survival increased after SRC,the need for dialysis decreased,and usually allowed the discontinuation of dialysis treatment within about 6-18 months.Suspicion of SRC in the presence of the above-mentioned findings in patients with a diagnosis or suspected systemic sclerosis can be considered the most important treatment step.
文摘Objective: To investigate the therapeutic potential of adipose-derived stern cells (ADSCs) for limited cutaneous scleroderma (LS) in mouse models. Methods: ADSCs were isolated from pathogen-free female C57BL/6 mice and LS was induced in wild type (WT) C57BL/6 mice via daily injection of bleomycin (0.1 mL x 300 mu g/mL) for 4 weeks; then the ADSCs were subcutaneously injected into the dorsal area in the model treatment group, and 100 mu L of phosphate buffered saline (PBS) solution was injected into the same site in the model control group. Green fluorescent protein (GFP) was used to track the cells using an in vivo imaging system on days 7, 14, 21 and 28 after transplantation. All mice were sacrificed and histologic analyses were performed after 4 weeks, and the skin thickness, collagen deposition and the total content of hydroxyproline were evaluated. Additionally, immunohistochemistry were performed to compare the tissue expression and distribution of TGF-beta 1 and VEGF between the ADSCs treatment group and the treatment control group. Results: WT C57BL/6 LS mouse model were successfully established and GFP in vivo fluorescence imaging showed that the translated ADSCs survived at the local for at least 4 weeks. Compared with the control group, the ADSCs treatment group significantly attenuated bleomycin-induced dermal fibrosis, reduced the skin thickness and the total content of hydroxyproline (P<0.05). The ADSCs treatment group displayed significantly lower levels of TGF-beta 1 and higher levels of VEGF than the control group (P<0.05). Conclusions: ADSCs may provide a feasible and practical treatment for autoimmune diseases such as LS and ameliorate dermal fibrosis.
文摘The purpose of the present study was to compare the effects of different doses of ultraviolet radiation A1 (UVA1) on human fibroblast proliferation and collagen level in a mouse model of scleroderma, so as to identify appropriate irradiation doses for clinical treatment of scleroderma. Monolayer from human fibroblasts was cultured in vitro, and a mouse model of scleroderma was established by subcutaneous injection of 100 μL of 400 μg/mL bleomycin into the back of BALB/c mice for 4 weeks. The mouse models and human fibroblasts were divided into UVA1- exposed (100, 60 and 20 J/cm2) and UVA-unexposed groups. At 0, 24 and 48 h after exposure, cell proliferation and levels of hydroxyproline and collagen were detected. UVA1 irradiation was performed 3 times weekly for 10 weeks, and the pathological changes of skin tissues, skin thickness and collagen level were observed after phototherapy. Cell proliferation and the levels of hydroxyproline and collagen were inhibited after phototherapy, and there was a significant difference between the UVAl-exposed cells and UVAl-unexposed cells (P 〈 0.001). In addition, UVA1 phototherapy improved dermal sclerosis and softened the skin, and there were significant differences between the high-dose UVA1 group and the model group, and the negative group (P 〈 0.05). It is concluded that UVA1 radiation can reduce cell proliferation, and decrease hydroxyproline and collagen levels in a dose-dependent manner in vitro. High-dose UVA1 phototherapy has marked therapeutic effect on scleroderma in the mouse model. Decreased collagen level may be related to the reduced number and activity of cells, as well as inhibition of collagen synthesis.
文摘Objective: To investigate the therapeutic effects of vitamine B 6 (Vit B 6) and Xuefu Zhuyu Decoction (血府逐瘀汤,XFZY, for activating blood circulation to remove stasis) in patients with localized scleroderma(LSD). Methods: Thirty-three patients were treated with XFZY and Vit B 6, with 15 cases taking orally prednisone acetate and 20 healthy volunteers as the control. Their level of soluble interleukin-2 receptor (sIL-2R) and tumor necrosis factor-α (TNF-α) in the patients with LSD before and after treatment were observed. Results: The level of sIL-2R and TNF-α in the serum from the patients with LSD were higher than those of healthy volunteers ( P <0.01). After treatment with Vit B 6 and XFZY, the level of sIL-2R and TNF-α from the patients with LSD decreased significantly ( P <0.01), but there were no difference between the group taking Vit B 6 plus XFZY and the group given prednisone. Conclusion: The activating blood circulation to remove stasis approach in treating LSD with integrative Chinese and Western drugs got better results, and metabolic disorder of tryptophan might be correlated with the etiology of LSD.
文摘Objective: Serum from SSc patients was analyzed centrally to determine ANA patterns and extractable nuclear antigens (ENAs) between lcSSc and dcSSc and associations with organ involvement. Methods: 1145 SSc patients had ANA and ENA analyzed by indirect immunofluorescence on HEp-2 substrate at a screening serum dilution of 1/160. Most ENA antibodies [Sm. U1-RNP, Ro52, SS-A/Ro60, topoisomeraseI (Topo1), SS-B/La, chromatin, ribosomal P and Jo1] were measured by laser bead immunoassay;and RNA polymerase III (RNAP) by ELISA. Results: ANA was positive in 95% (same in lcSSc, and dcSSc). Centromere pattern was present in 34%, speckled 22%, nucleolar 18%, homogeneous and speckled (H&S) 16%, multiple nuclear dots 6%. Anti-centromere Ab (ACA) occurred in 46% of lcSSc and 11% of dcSSc (P = 0.0001). ENAs that differed between lcSSc and dcSSc subsets were Topo1 (OR 2.4, P = 0.0001) and RNAP (OR 5.6, P 0.0001) more common in dcSSc. Overall, 15% had positive Topo1;usually with a H&S pattern (67%);Topo1 was associated with ILD on CXR (OR 2.3;95% CI 1.5 - 3.5) and HRCT (OR 3.8;95% CI 1.8 - 8.2). RNAP occurred in 18.5% (35.4% in dcSSc vs. 8.9% in lcSSc). Scleroderma renal crisis (SRC) was 13 times more likely if RNAP positive;P = 0.0001. ACA was only weakly associated with sPAP > 50 mmHg (OR 1.8;95%CI 1.1 - 3.0). Conclusion: ANA homogeneous pattern alone is rare in SSc;ACA was significantly more common in lcSSc. Many ENAs are equal in lcSSc and dcSSc except RNAP and Topo1. RNAP has the highest OR of SRC. Topo1 is less strongly associated with ILD. Abstract word count: 249, Body word count 1246, Figures 2, Tables 2. Key Messages: 1) 95% of SSc has a positive ANA and ANA patterns in SSc include centromere, nucleolar, and homogeneous and speckled together;2) Most ENAs are equal in both dcSSc and lcSSc except anti RNA polymerase III and topoisomerase I;3) RNA polymerase III has the highest association (odds ratio) with scleroderma renal crisis, topoisomerase I is associated with interstitial lung disease;whereas anticentromere was not associated with elevated pulmonary arterial pressures on echocardiogram.
文摘Objectives: Digital refractory gangrene is rarely found in collagen diseases, including systemic sclerosis and is possibly caused by similar underlying vascular damage in peripheral arterial disease (PAD) such as arteriosclerosis obliterans (ASO) and/or thromboangiitis obliterans (TAO) by unclarified mechanisms other than vasculitis and thrombosis. This study evaluated the radiological imaging in patients with digital gangrene associated with collagen disease and compared the images with those of PAD based on the results of laboratory and histopathological examinations. Methods: Angiography, MR angiography and/or CT angiography were performed on 6 patients with refractory gangrene or extensive ulcers accompanied by scleroderma-spectrum disorders;3 with diffuse systemic sclerosis, 1 with limited systemic sclerosis, 1 with overlap syndrome and 1 with Sj?gren’s syndrome. Results: Although the vascular alterations in collagen diseases were similar to those in PAD, the abnormal image findings (occlusion or stenosis of the arteries with smooth vessel walls) found in collagen diseases did not include atheromatous plaque, which are worm-like vessels that are characteristic of those observed in PAD. Conclusions: Some cases of digital gangrene seen in collagen diseases show similar vascular imaging patterns to those of PAD and comprehensive examinations including arterial imaging can be useful for the diagnosis of these unrecognized vascular changes other than vasculitis or digital thrombosis.
文摘Evidence suggests that B cells may participate in the fibrotic process Based on this experimental evidence, treatment with rituximab(RTX) has been tried in systemic sclerosis(SSc) with promising results. In a randomized controlled study from our research group it was shown that treatment with 2 courses of RTX leads to a significant improvement of lung function at 1 year compared to baseline. All relevant studies have so far reported clinical and/or histologic improvement of skin fibrosis something that adds further evidence in favor of a disease modifying role of RTX in SSc. It is more than obvious that novel therapies for SSc-associated lung disease are needed. A large scale, randomized, controlled study assessing the efficacy of RTX in SSc associated interstitial lung disease is warranted. If RTX turns out to be effective it would be a major therapeutic advance in SSc since it can be administered on a long term basis due to its acceptable safety profile.
文摘Scleroderma(or systemic sclerosis) is a rare disease associated with significant morbidity and mortality.Although previously thought to have a uniformly poor prognosis,the outlook has changed in recent years.We review recent insights into the pathogenesis,clinical features,assessment and management of scleroderma.
文摘Aim: The aim of this study is to describe the clinical characteristics of patients with a diagnosis of systemic sclerosis who later suffer a stroke and to identify associations for this relationship. Background: Prior studies have showed an increased risk of cardiovascular disease among patients with chronic inflammatory disorders, with chronic inflammation leading to atherosclerosis believed to be the culprit. Systemic sclerosis (SSc) is a chronic inflammatory disease characterized by diffuse fibrosis of the skin and internal organs. Previous studies have suggested a possible link between systemic sclerosis and macrovascular complications such as stroke. Methods: This is a retrospective chart review of patients treated within the University of Pennsylvania Health System from October 2015 to April 2019 with a diagnosis of SSc. Using ICD10 codes, we identified a cohort of SSc patients who suffered a stroke. Information regarding demographics and stroke risk factors were gathered from the charts of patients with a diagnosis of both SSc plus stroke and compared to a control group of randomly selected patients with SSc who never suffered a stroke. Continuous variables were conveyed using a mean plus a standard deviation. A two-sample t-test was used to compare the two groups of patients. Qualitative variables were compared using a two-tailed Fisher’s exact test. Results: Based on a large cohort of SSc patients (n = 2080) followed between October 2015 and April 2019, we identified 36 SSc patients who developed a subsequent stroke (1.7% of cohort). When looking at risk factors for stroke in SSc patients, we identified hypertension and atrial fibrillation to be associated with the diagnosis of stroke in such patients. Specifically, 28 of the 36 patients with both SSc and stroke also had a diagnosis of hypertension while in the control group, only 17 of 36 patients had hypertension. Atrial fibrillation was seen in 9 of 36 patients with both SSc and CVA while it was seen in only 2 of 36 patients in the control group. Conclusions: This case control study demonstrated that the presence of hypertension and atrial fibrillation had a statistically significant association with the diagnosis of CVA in patients with SSc.
文摘We hereby present a case of anaemia in a 73 years old patient with known past medical history of diffuse systemic scleroderma, who presented with acute onset of dizziness and haemetemesis. Blood tests revealed sudden drop of haemoglobin and an urgent gastroscopy revealed gastric antral vascular ectasia (GAVE) or “watermelon stomach”. GAVE is a rare but well recognised cause of acute bleeding in systemic scleroderma patients and should be kept as a differential diagnosis in the work up of anaemia in these patients.
文摘IntroductionThe association between pulmonary interstitial fibrosis and the development of bronchogenic carcinoma in a patient with scleroderma has been reported rarely. It is hypothesized that intense epithelial proliferation that is accompanied by the .brotic process increases the occurrence of carcinomatous changes. We report the case of a pa-tient who presented with 3-year history of Raynaud's phenomenon, gradual tightening of the skin which was ignored by the patient and her family members, and a 2-week history of severe respiratory dis-tress with left shoulder and upper back pain followed by the develop-ment of paraparesis. After a series of examinations, the patient was diagnosed with scleroderma and simultaneously with bronchogenic carcinoma and multiple distant metastases.
文摘Systemic sclerosis (scleroderma) is a connective tissue disease characterized by vascular dysfunction and fibrosis that can affect multiple organ systems. We present case of primary cardiac involvement and the diagnostic role of cardiac MRI. Cardiovascular magnetic resonance imaging (MRI) is an accurate, quantitative method for the non-invasive assessment of myocardial perfusion. The presence of clinically apparent myocardial involvement in scleroderma portends a very poor prognosis. One study of US veterans found that clinical cardiac disease in scleroderma was associated with a 70% mortality rate at five years. Management of heart failure and conduction system abnormalities in scleroderma is similar to other cardiac disease. It includes afterload reduction, beta-blockade, defibrillator placement, etc. Patients with reduced cardiac function and normal coronary arteries may benefit from increased immune suppresion.
文摘Objective: To investigate the effects of connective tissue growth factor(CTGF) and collagen type I(COL-I) on the pathogenesis of scleroderma and explore the relationship between the level of COL-I and CTGF. Methods: 12 mice model of scleroderma was established by the injection of Bleomycin. The level of CTGF and COL-I were detected by immunohistochemical method. The relationship was analyzed between CTGF and COL-I level. As control group, 12 healthy mice were selected. Results: The levels of CTGF and COL-I in sclerotic models were higher than in normal controls (P 〈 0.05). It was found that there was a correlation between the level of CTGF and COL-I. Conclusion: CTGF and COL-I played an important role in the hardening process of the skin lesions of the mice model, which may be involved in the pathogenesis of scleroderma.
文摘Objective: The aim of this study was to describe the epidemiological, clinical and therapeutic features of systemic scleroderma at Cocody UTH. Methodology: We conducted a retrospective and descriptive study over a period of 10 years (September 15, 2008 to April 15, 2019) on the files of patients hospitalized for systemic scleroderma in the rheumatology unit of the UTH of Cocody. We used the classification criteria of the American Society of Rheumatology (1980) to retain the diagnosis. Results: Nineteen patients’ files had been collected, representing a hospital frequency of 0.32%. The average age was 37.25 ± 13.82 years old. There were 15 women and 4 men. The average consultation time was 26.44 months. The mode of revelation of the disease was mostly cutaneous and articular. All patients had cutaneous sclerosis (average Rodnan score = 27.63/11.61 (min = 4, max = 49).) Scleroderma was diffuse in 70.59% of cases;a Raynaud’s phenomenon was seen in 47.37%. The main clinical manifestations were: cutaneous (100%), articular (89.47%), pulmonary (57.89%) and digestive (63.16%). No renal damage was found. Pulmonary fibrosis (5 cases), pulmonary arterial hypertension (3 cases) and pericardial effusion (2 cases) were sometimes founded in explorations. The positivity of antinuclear antibodies (ANA) was seen in 72% of patients and anti scl70 antibodies in 42.85%. The treatment included corticosteroids and immunosuppressants, respectively used in 84.2% and 63.16% of cases. The outcome was marked by 5 cases of death attributed to respiratory distress. Conclusion: Systemic scleroderma seems to be a very rare condition in Ivorian rheumatology milieu. The main systemic manifestations were digestive and pulmonary. Treatment was very often symptomatic sometimes associated with D-penicillamine.

文摘Objective:To investigate the effect of cetirizine on the fibrosis of skin tissue in systemic sclerosis(SSc)mice and its mechanism of action.Methods:Thirty-two BALB/C mice were randomly divided into a blank group,a model group,a cetirizine low-dose group,and a cetirizine high-dose group,with eight in each group.The blank group was injected with normal saline on the back,and the other three groups were injected with bleomycin on the back to prepare SSc mouse models.The mice were injected once a day for 28 consecutive days,while the normal group and the model group were given saline.The dose group was administrated intragastrically at 2 mg/kg and 5 mg/kg,respectively,for 28 consecutive days.Detect the thickness of the dermis by taking the skin tissue in the back injection area of each group.Hematoxylin-eosin staining(HE)and Masson staining.Sample hydrolysis method to detect hydroxyproline(HYP)content in skin tissue.Immunohistochemical detection ofα-smooth muscle actin(α-SMA)expression in skin tissues.Enzyme-linked immunosorbent assay(ELISA)to detect serum interleukin(IL-6,IL-10)and transforming growth factor(TGF-αand TGF-β1).Quantitative real-time PCR(qRT-PCR)was used to detect the expression levels of collagen type I(COL1A1),type III collagen(COL3A1),Smad homolog 3(Smad3),and TGF-β1 mRNA.Western blot was used to detect the expression levels of COL1A1,COL3A1 and p-Smad3.Results:Compared with the blank group,the dermis thickness and HYP content of the model group increased,the skin tissue lesions and fibrosis were more severe,theα-SMA positive expression intensity in the skin tissue was higher,and the serum IL-6,IL-10,TGF-α,TGF-β1 content increased,COL1A1,COL3A1,Smad3,TGF-β1 mRNA expression levels increased in skin tissues,COL1A1,COL3A1,p-Smad3 protein expression increased,the differences were statistically significant(P<0.05).Compared with the model group,the dermal thickness and HYP content of the low and high dose cetirizine groups were reduced,the degree of skin tissue lesions and fibrosis was improved,the expression ofα-SMA in skin tissues was weakened,the levels of IL-6,IL-10,TGF-α,TGF-β1 in serum were reduced,the expression levels of COL1A1,COL3A1,Smad3 and TGF-β1 in skin tissues were reduced,and the expression levels of COL1A1,COL3A1,and p-Smad3 proteins were reduced,the decrease in the high-dose group was more significant,and the differences were statistically significant(P<0.05).Conclusion:Cetirizine can improve the degree of fibrosis of skin tissue in SSc mice and reduce the immune inflammation response.The mechanism of action is related to the TGF-β1/Smad3 signaling pathway.
文摘Introduction: Scleroderma is a generalized condition of the connective tissue, arterioles and micro-vessels characterized by tissue fibrosis, vascular obliteration and abnormal humoral and cellular immune responses. The aim of this study was to describe the epidemiological, clinical, therapeutic and evolutionary aspects of scleroderma at the Department of Dermatology-Venerology at Donka National Hospital. Methods: This was a descriptive cross-sectional study with a retrospective collection of data for a period of 11 years, from January 1, 2000, to December 31, 2010, covering all inpatient records of Scleroderma in the service. Results: We collected 17 cases of scleroderma out of 3289, a frequency of 0.04%. The average age of patients was 33.33 years with extremes of 10 and 60 years. A female predominance was noted with a sex ratio M/F of 0.13. Cutaneous induration was the main symptom associated with the phenomenon of Raynaud, and disorders of pigmentation. The extra-skin manifestations were mainly dominated by gastrointestinal involvement (32%), pulmonary involvement (24%), cardiac (20%), articular (20%) and renal (12%) involvement. The systemic form was the most common (99.45%). Corticotherapy was the most prescribed treatment (24.59%). Clinical improvement was noted in (93.2%) of the cases. Conclusion: Scleroderma, although rare, deserves special attention at all levels for early diagnosis.
文摘Introduction: Acquired immunodeficiency syndrome (AIDS) linked to HIV infection is accompanied by auto-immune phenomena. Autoimmune diseases can develop in people living with HIV, most in a context of good immunological control (vasculitis, anti-phospholipid syndrome). Since the advent of antiretroviral therapy, an increasing number of autoimmune connective tissue diseases such as systemic lupus erythematosus, dermatomyositis, and syndromes of Sj?gren and scleroderma have been reported. Purpose: To describe this association’s not very common scleroderma and HIV infection. Observation: We report the case of a 56-year-old lady admitted into the service for functional impotence that would have been evolving for a week. Prior to her hospitalization, she presented edemas of the lower limbs associated with anesthesia of the lower limbs for 5 months. The painting is accompanied by a productive cough and an intermittent fever. At the physical examination a weight loss (BMI = 13.74 Kg/m2), fever (38.7°C): Oral candidiasis, lower lip ulceration, perlicking, undernutrition folds, sclerodactyly and homogeneous hepatomegaly was noted. The diagnosis of immunosuppression to HIV Stage 3 with TB co-morbidity and positive hepatitis B Serology was retained while diffuse Scleroderma was selected from the ACR/EULAR criteria of 2012 with a score of 10 (sclerodactyly = 4 point;Raynaud’s phenomenon = 3 point and Ac Anti Scl 70 positive = 3 point). Conclusion: These associations of chronic pathology must be described to improve the future treatment of our patients.
