METHODSA cross-sectional study examining the results of upper endoscopy and colonoscopy in adults with dermatomyositis at an urban, university hospital over a ten year period was performed. Chart review was performed to confirm the diagnosis of dermatomyositis. Findings on endoscopy were collected and statistical analyses stratified by age and presence of symptoms were performed. RESULTSAmong 373 adult patients identified through a code based search strategy, only 163 patients had dermatomyositis confirmed by chart review. Of the 47 patients who underwent upper endoscopy, two cases of Barrett’s esophagus without dysplasia were identified and there were no cases of malignancy. Of the 67 patients who underwent colonoscopy, no cases of malignancy were identified and an adenoma was identified in 15% of cases. No significant differences were identified in the yield of endoscopy when stratified by age or presence of symptoms. CONCLUSIONThe yield of endoscopy is low in patients with dermatomyositis and is likely similar to the general population; we identified no cases of malignancy. A code based search strategy is inaccurate for the diagnosis of dermatomyositis, calling into question the results of prior population-based studies. Larger studies with rigorously validated search strategies are necessary to understand the risk of gastrointestinal malignancy in patients with dermatomyositis.展开更多

Methods: 30 consecutive patients with DM/PM and 23 healthy controls were recruited into current study. Anti-JO-1, anti-SSA, muscle enzymes, the data of chest HRCT and pulmonary function test were collected. 9 consecutive DM/PM-ILD patients underwent bronchoalveolar lavage (BAL). TGF-β1 and surfactant protein D (SP-D) in BAL fluid (BALF) and plasma were detected by ELISA. miR-125b and miR-200c in PBMCs and bronchoalveolar cells were detected by QRT-PCR. All patients were classified into three groups: Mild or non-ILD group, moderate ILD group, and severe ILD group. The correlations between miRNAs and the severity of ILD, the lung damage markers, auto-antibodies, were analyzed. Results: The levels of miR-125b and miR-200c in bronchoalveolar cells were higher than in PBMCs, and the levels of TGF-β1 and SP-D were higher in BALF than in plasma in DM/PM-ILD patients. There were positive correlations between miR-125b, miR-200c in bronchoalveolar cells and SP-D in BALF. The levels of miR-125b and miR-200c in severe ILD group were higher than in mild or non-ILD and moderate ILD groups. There were negative correlations between miR-125b, miR-200c, and FEV1, and between miR-200c and DLCO. The patients with anti-JO-1 antibody had higher levels of miR-125b and miR-200c, and had more severe condition of ILD. Conclusion: miR-125b and miR-200c were positively correlated with the lung damage and severity of ILD in DM/PM, which could be important markers for judgement of disease condition in clinic.展开更多

There have currently no studies that evaluated the safety and efficacy of tDCS in patients with dermatomyositis. Case-report: Three adult women with dermatomyositis were allocated randomly to intervention (i-tDCS, one patient) or not (sham-tDCS, two patients) of three consecutive days of tDCS and evaluated in four periods: before-tDCS (PRE), 15 minutes after-tDCS (0th POST), 15 days after-tDCS (15th POST), and 30 days after-tDCS (30th POST). The tDCS was safe throughout the protocol, without disease relapsing or adverse effects related to tDCS. Furthermore, the tDCS increased the muscle torque and total work of dominant and non-dominant elbow flexors in the patient with i-tDCS, when compared to two patients with sham-tDCS. Conclusions: The tDCS was safe and appeared to influence long-term strength in the limb of the patient with stable dermatomyo-sitis.展开更多

We describe a case index of 50-year-old female who presented with enlarged inguinal lymph nodes accompanied with symmetric proximal muscle weakness and erythematous plaques. Conventional basic work-up did not reveal the diagnosis,however,positron emission tomography-computed tomography and re-staining of the pathology specimen suggested the ovaries as the primary site. Chemotherapy including carboplatin paclitaxel and bevacizumab led to complete response of disease and improvement in the dermatomyositis. The present case emphasizes the importance of a thorough directed evaluation for the underlying cancer in patients with carcinoma of unknown primary presenting as dermatomyositis. We further provide an up-to-date detailed review of published data describing these clinical entities.展开更多

To corroborate the literature, we described a refractory dermatomyositis that had a good outcome with tofacitinib. Case Report: An adult female patient presented with definite dermatomyositis and with refractoriness to high doses of intravenous and oral glucocorticoids, intravenous human immunoglobulin, several immunosuppressive drugs (methotrexate, azathioprine, and leflunomide) and two previous immunobiological drugs (rituximab and abatacept). However, the patient had a good outcome with tofacitinib. Conclusions: Tofacitinib appears to be a promising alternative therapy for refractory dermatomyositis.展开更多

There is no standard curative treatment for calcinosis but different agents were used with variable efficacy. We report the favorable outcome of rituximab on severe calcinosis in 4 JDM patients and present their clinical data. Patients and Methods: A retrospective chart review of 4 children with JDM and severe calcinosis who received rituximab for relapsing or polycyclic JDM course. Diagnosis and follow up of calcinosis was clinically and by X-ray. Review data included: age of patients at onset of JDM symptoms and diagnosis, clinical and laboratory criteria at diagnosis, disease course and duration of follow up. Data about calcinosis onset, sites, severity and its progression were also included. Further data about rituximab therapy included: dosage, side effects, other treatment used before, during or after this drug and outcome and duration of follow up of calcinosis after therapy. Results: 4 patients (2 male, 2 female), interval between onset of symptoms and diagnosis was 6 - 12 months, course of JDM was polycyclic or relapsing, duration of follow up was 5 - 7 years. Calcinosis was severe causing ulceration, recurrent skin infections and joint limitation. It was not improving despite treatment with different DMARDs and/or bisphosphonates, colchicine and warfarin. Reason to start rituximab was inadequate disease control with conventional DMARDs. All patients received steroids and more than one DMARD before starting rituximab and were continued thereafter, follow up after rituximab was 3 to 5 years. All patients had improvement in disease activity and frequency of admission especially due to complications of calcinosis. One patient had complete clearance of calcinosis for the last 5 years. Others had significant improvement in calcinosis with no new lesions, decreased sites and density and decreased calcinosis related contractures. There were no serious side effects to rituximab. Conclusion: Our study showed the favorable effect of rituximab in treatment of calcinosis in 4 patients with JDM-associated severe calcinosis when it was used with other conventional DMARDs.展开更多

In addition, our results showed that tDCS sessions are safe and do not lead to disease relapse. Therefore, despite the limitations of being a case report, this study provides encouraging results that need to be widely explored in studies with a representative number of patients and with an appropriate design for patients with this systemic rheumatic autoimmune disease.展开更多

文摘BACKGROUND Joint,skin,oral cavity,and eye lesions are the most common extraintestinal manifestations of ulcerative colitis that can occur before or after its onset.The cases of ulcerative colitis with dermatomyositis(DM)are rare.In this study,we report a rare case of ulcerative colitis with DM that was effectively treated with infliximab.CASE SUMMARY The patient was a 57-year-old female with a 2-year history of DM.The patient was admitted to hospital with abdominal pain,diarrhea,and blood in stool lasting for more than 2 mo.Colonoscopy revealed multiple erosions and ulcers in the entire colon and rectum.Pathological sections showed chronic inflammatory cell infiltration,especially neutrophil infiltration,in the colonic mucosa;therefore,the patient was diagnosed with ulcerative colitis.Preparations of 5-aminosalicylic acid was added to her treatment based on the original treatment for DM,but its effect was unsatisfactory.The patient’s discomfort was relieved after infliximab treatment.CONCLUSION Infliximab can improve DM in the treatment of ulcerative colitis.Specialists need to raise awareness about patients with inflammatory bowel disease who have rare extraintestinal manifestations.
文摘Objective: To explore the correlations between miR-125b, miR-200c, and the severity of interstitial lung disease associated with dermatomyositis/polymyositis (DM/PM-ILD). Methods: 30 consecutive patients with DM/PM and 23 healthy controls were recruited into current study. Anti-JO-1, anti-SSA, muscle enzymes, the data of chest HRCT and pulmonary function test were collected. 9 consecutive DM/PM-ILD patients underwent bronchoalveolar lavage (BAL). TGF-β1 and surfactant protein D (SP-D) in BAL fluid (BALF) and plasma were detected by ELISA. miR-125b and miR-200c in PBMCs and bronchoalveolar cells were detected by QRT-PCR. All patients were classified into three groups: Mild or non-ILD group, moderate ILD group, and severe ILD group. The correlations between miRNAs and the severity of ILD, the lung damage markers, auto-antibodies, were analyzed. Results: The levels of miR-125b and miR-200c in bronchoalveolar cells were higher than in PBMCs, and the levels of TGF-β1 and SP-D were higher in BALF than in plasma in DM/PM-ILD patients. There were positive correlations between miR-125b, miR-200c in bronchoalveolar cells and SP-D in BALF. The levels of miR-125b and miR-200c in severe ILD group were higher than in mild or non-ILD and moderate ILD groups. There were negative correlations between miR-125b, miR-200c, and FEV1, and between miR-200c and DLCO. The patients with anti-JO-1 antibody had higher levels of miR-125b and miR-200c, and had more severe condition of ILD. Conclusion: miR-125b and miR-200c were positively correlated with the lung damage and severity of ILD in DM/PM, which could be important markers for judgement of disease condition in clinic.
文摘A case of dermatomyositis associated with hepatocellular carcinoma is reported in a 43-year-old man,in which removal of the tumor resulted in great improvement of dermatomyositis.The patient had shown aggravating symptoms of dermatomyositis including manifestations of typical skin rashes and muscle weakness six months before he came to our hospital.He had no history of drug allergy and took no medicine in these days.When first visiting the dermatological clinic,he complained of discomforts in skin and muscle manifestation and was diagnosed as having dermatomyositis.At the same time,A CT scan discovered a resectable liver tumor in the right lobe.Then he came to our hospital and asked for surgical treatment.Removal of the tumor resulted in great improvement of dermatomyositis and recurrence of liver tumor was followed by resumption of dermatomyositis.

文摘BACKGROUND Dermatomyositis(DM) is a rare autoimmune disease involving the connective tissue.The association between DM and gastric cancer remains unclear.Patients with DM have an increased risk of cancer and higher mortality.It requires immunosuppressive therapy,heightened surveillance,and immunologic response to internal malignancy.CASE SUMMARY Two cases of gastric cancer with DM as the first symptom in Zhongshan Hospital,Fudan University(Shanghai,China) were reported.Two patients had a typical skin rash.The rash in the first patient involved mainly bilateral upper limbs and neck,while the second patient manifested rash associated mainly with the face,neck,and back.Both manifested muscle weakness in the extremities and elevated serum creatine kinase.Radical resection of the tumor dramatically improved DMrelated symptoms in the two patients.The literature review showed that gastric cancer is more commonly associated with DM in middle-aged and older male populations.CONCLUSION The findings suggest the need for comprehensive screening for malignant tumors in patients with DM refractory to long-term pharmacotherapy or hormone manipulation.

文摘BACKGROUND Pneumocystis jiroveci pneumonia(PJP)is a serious opportunistic infection that occurs mostly in patients with immunodeficiency and long-term immunosuppressive therapy.In non-human immunodeficiency virus-infected patients,the most important risk factor for PJP is the use of glucocorticoids in combination with other immunosuppressive treatments.The management of glucocorticoids during the perioperative period in patients with dermatomyositis requires special care.CASE SUMMARY We report a case of PJP in the perioperative period.A 61-year-old woman with a history of anti-melanoma differentiation-associated gene 5(MDA5)-positive dermatomyositis and interstitial pneumonia was administered with long-term oral methylprednisolone and cyclosporine.The patient underwent right total hip arthroplasty in the orthopaedic department for bilateral osteonecrosis of the femoral head.She was given intravenous drip hydrocortisone before anesthesia and on the first day after surgery and resumed oral methylprednisolone on the second postoperative day.On the fifth day after surgery,the patient suddenly developed dyspnea.The computed tomography scan showed diffuse grid shadows and ground glass shadows in both lungs.Polymerase chain reaction testing of bronchoalveolar lavage fluid was positive for Pneumocystis jiroveci.The patient was eventually diagnosed with PJP and was administered with oral trimethoprim-sulfamethoxazole.At the 6-mo review,there was no recurrence or progression.CONCLUSION Continued perioperative glucocorticoid use in patients with anti-MDA5-positive dermatomyositis may increase the risk of PJP.

文摘Transcranial direct current stimulation (tDCS) has emerged as a nonpharmacological tool in physical rehabilitation. There have currently no studies that evaluated the safety and efficacy of tDCS in patients with dermatomyositis. Case-report: Three adult women with dermatomyositis were allocated randomly to intervention (i-tDCS, one patient) or not (sham-tDCS, two patients) of three consecutive days of tDCS and evaluated in four periods: before-tDCS (PRE), 15 minutes after-tDCS (0th POST), 15 days after-tDCS (15th POST), and 30 days after-tDCS (30th POST). The tDCS was safe throughout the protocol, without disease relapsing or adverse effects related to tDCS. Furthermore, the tDCS increased the muscle torque and total work of dominant and non-dominant elbow flexors in the patient with i-tDCS, when compared to two patients with sham-tDCS. Conclusions: The tDCS was safe and appeared to influence long-term strength in the limb of the patient with stable dermatomyo-sitis.
文摘NASOPHARYNGEAL carcinoma (NPC) is a raredisease in North America and Western Europe,but is common in Asia and North Africa.1,2 Asmall percentage of NPC patients present withparaneoplastic syndrome and less than 0.1% with dermatomyositis.2 No prospective case-control double-blindedstudies of immunosuppressive therapy in dermatomyositishave been performed, let alone in paraneoplastic dermatomyositis.
文摘Dermatomyositis is known to be associated with neoplastic disorders,however the presentation of carcinoma of unknown primary as dermatomyositis is rare. We describe a case index of 50-year-old female who presented with enlarged inguinal lymph nodes accompanied with symmetric proximal muscle weakness and erythematous plaques. Conventional basic work-up did not reveal the diagnosis,however,positron emission tomography-computed tomography and re-staining of the pathology specimen suggested the ovaries as the primary site. Chemotherapy including carboplatin paclitaxel and bevacizumab led to complete response of disease and improvement in the dermatomyositis. The present case emphasizes the importance of a thorough directed evaluation for the underlying cancer in patients with carcinoma of unknown primary presenting as dermatomyositis. We further provide an up-to-date detailed review of published data describing these clinical entities.
文摘In very scarce case reports and case series, tofacitinib has been a therapeutic alternative for dermatomyositis. To corroborate the literature, we described a refractory dermatomyositis that had a good outcome with tofacitinib. Case Report: An adult female patient presented with definite dermatomyositis and with refractoriness to high doses of intravenous and oral glucocorticoids, intravenous human immunoglobulin, several immunosuppressive drugs (methotrexate, azathioprine, and leflunomide) and two previous immunobiological drugs (rituximab and abatacept). However, the patient had a good outcome with tofacitinib. Conclusions: Tofacitinib appears to be a promising alternative therapy for refractory dermatomyositis.
文摘Background: Calcinosis is an important sequela of JDM which may cause significant morbidity and mortality. There is no standard curative treatment for calcinosis but different agents were used with variable efficacy. We report the favorable outcome of rituximab on severe calcinosis in 4 JDM patients and present their clinical data. Patients and Methods: A retrospective chart review of 4 children with JDM and severe calcinosis who received rituximab for relapsing or polycyclic JDM course. Diagnosis and follow up of calcinosis was clinically and by X-ray. Review data included: age of patients at onset of JDM symptoms and diagnosis, clinical and laboratory criteria at diagnosis, disease course and duration of follow up. Data about calcinosis onset, sites, severity and its progression were also included. Further data about rituximab therapy included: dosage, side effects, other treatment used before, during or after this drug and outcome and duration of follow up of calcinosis after therapy. Results: 4 patients (2 male, 2 female), interval between onset of symptoms and diagnosis was 6 - 12 months, course of JDM was polycyclic or relapsing, duration of follow up was 5 - 7 years. Calcinosis was severe causing ulceration, recurrent skin infections and joint limitation. It was not improving despite treatment with different DMARDs and/or bisphosphonates, colchicine and warfarin. Reason to start rituximab was inadequate disease control with conventional DMARDs. All patients received steroids and more than one DMARD before starting rituximab and were continued thereafter, follow up after rituximab was 3 to 5 years. All patients had improvement in disease activity and frequency of admission especially due to complications of calcinosis. One patient had complete clearance of calcinosis for the last 5 years. Others had significant improvement in calcinosis with no new lesions, decreased sites and density and decreased calcinosis related contractures. There were no serious side effects to rituximab. Conclusion: Our study showed the favorable effect of rituximab in treatment of calcinosis in 4 patients with JDM-associated severe calcinosis when it was used with other conventional DMARDs.
文摘To the best of our knowledge, this is the first report in the literature showing the efficacy of transcranial direct current stimulation (tDCS) in treating refractory post-herpetic neuralgia in a patient with dermatomyositis. In addition, our results showed that tDCS sessions are safe and do not lead to disease relapse. Therefore, despite the limitations of being a case report, this study provides encouraging results that need to be widely explored in studies with a representative number of patients and with an appropriate design for patients with this systemic rheumatic autoimmune disease.
文摘A 51-year old male who presented at our hospital for recurrent palpitation for several months was diagnosed dermatomyositis ten years ago and had interstitial lung disease since two years ago. Recently, he was admitted for atypical hepatitis, and received maintenance treatment of oral corticosteroids.
文摘We report a case of a 56-year-old female with a confirmed diagnosis of Dermatomyositis on muscle biopsy, which was refractory to 5 different disease modifying drugs as well as intravenous immunoglobulins and symptoms improved dramatically with a single course of Rituximab. We hereby wish to highlight the importance of Rituximab in this highly resistant case and that anti CD 20 biologic drugs can be considered as standard treatment protocol in refractory Dermatomyositis.
