Objective:To evaluate the predictive value of the neutrophil⁃to⁃lymphocyte ratio(NLR)and the systemic immune⁃inflammation index(SII)in predicting patients with anti⁃melanoma differentiation⁃associated gene 5⁃positive(anti⁃MDA5+)dermatomyositis(DM)develop into the rapidly progressive interstitial lung disease(RPILD).Methods:We retrospectively analyzed the clinical and laboratory data of 124 anti⁃MDA5+DM patients from the First Affiliated Hospital of Nanjing Medical University between March 2019 and September 2023.We identified independent risk factors associated with the development and mortality of RPILD with the Cox regression analysis,and determined the optimal cut⁃off values for predicting adverse outcomes with the receiver operating characteristic(ROC)curve analysis.Results:Among the 124 patients,36 patients(29.03%)developed RPILD,and 39 patients(31.45%)died during the follow⁃up period.The results of multivariate Cox regression analysis showed that the elevated NLR was an independent risk factor for RPILD development,while the elevated SII expression was independently associated with the increased mortality of RPILD.Based on the ROC curve analysis,NLR>6.12 was a predictor for RPILD,and SII>875.79 was associated with increased mortality risk of RPILD.Conclusion:Both NLR and SII are accessible,cost⁃effective,and reliable prognostic indicators for the prognosis of patients with anti⁃MDA5^(+)DM,providing a valuable guidance for clinical management and risk stratification of the disease. 展开更多

BACKGROUND Twenty percent of patients infected with hepatitis B virus(HBV)develop extrahepatic manifestations with HBV detected in the lymph nodes,spleen,bone marrow,kidneys,and skin.HBV infection has been associated with some autoimmune disorders.Dermatomyositis(DM)is an idiopathic inflammatory myopathy,which involves a viral infection,and DM has been identified in patients infected with HBV,but there is no direct histological evidence for an association between HBV and DM.CASE SUMMARY We describe a familial HBV-infected patient admitted with liver function abnormality,rashes,a movement disorder,and an elevated level of creatine kinase(CK).A computed tomography scan of the lung showed pulmonary fibrosis,and a liver biopsy identified nodular cirrhosis.An electromyogram revealed myogenic damage,and a muscle biopsy showed nuclear migration in local sarcolemma and infiltration of chronic inflammatory cells.Immunohistochemical staining showed negative results for HBsAg and HBcAg.Fluorescence in situ hybridization showed a negative result for HBV DNA.The patient was diagnosed with HBV-related liver cirrhosis complicated with DM and was treated with methylprednisolone,mycophenolate mofetil,and lamivudine.Eight months later,the patient was readmitted for anorexia and fatigue.The blood examination showed elevated levels of aminotransferases and HBV DNA,however,the CK level was within the normal range.The patient developed a virological breakthrough and lamivudine was replaced with tenofovir.CONCLUSION DM in chronic HBV-infected patients does not always associate with HBV.Antiviral and immunosuppressive drugs should be taken into consideration. 展开更多

She refused therapy for HCC. Nine months after the diagnosis, she developed dermatomyositis when the HCC enlarged to a diameter of 6.0 cm. She underwent therapy for dermatomyositis, and then transcatheter arterial chemoembolization for HCC. Although the manifestations of dermatomyositis improved and entire tumor necrosis was achieved, she died of pneumonia 2 mo after the treatment of HCC. HCC and/or chronic hepatitis C virus infection might be involved in the pathogenesis of dermatomyositis. 展开更多

Patients with gallbladder carcinoma can present with a variety of paraneoplastic syndromes,including Cushing's syndrome,hypercalcemia,acanthosis nigricans,bullous pemphigoid,dermatomyositis and the sign of Leser-Trélat.Surgical resection of the primary tumor results in resolution of these paraneoplastic syndromes.We present a 67-year old female with facial and cervical erythema who was initially diagnosed with dermatomyositis.However,an abdominal computed tomography(CT)and positron emission tomographyCT scan was suspicious for gallbladder carcinoma with lymph node metastasis.After surgical resection,her dermatomyositis was resolved.This case demonstrates that dermatomyositis may be a manifestation of preexisting gallbladder carcinoma. 展开更多

To determine the prevalence of gastrointestinal neoplasia among dermatomyositis patients who underwent an esophagogastroduodenoscopy and/or colonoscopy. 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

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. 展开更多

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. 展开更多

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. 展开更多

Dermatomyositis(DM)is an idiopathic inflammatory myopathy characterized by prominent skin lesions,muscle weakness,and clinically heterogeneous systemic manifestations.Among patients with DM,the male-to-female ratio is 2:1.Juvenile dermatomyositis(JDM)is most prevalent between the ages of 4 and 14 years,while adult-onset dermatomyositis typically occurs between the ages of 40 and 60 years.In a population-based study conducted in Olmsted County,Minnesota,USA,the risk of DM was found to increase with age across different age groups stratified by decade.The incidence rate of DM in individuals aged≥80 years was 3.2 per 100,000 person-years.Dermatomyositis in elderly patients is characterized by unique clinical manifestations,pathogenic mechanisms,and therapeutic approaches.However,discussions regarding geriatric dermatomyositis are currently limited.Therefore,this article aims to review the epidemiology,clinical features,histopathology,and pathogenesis of dermatomyositis,with a particular focus on the unique clinical characteristics of geriatric dermatomyositis. 展开更多

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. 展开更多

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. 展开更多

AIM:To evaluate detailed anterior segment parameters of patients with idiopathic inflammatory myopathies(IIM),including polymyositis(PM),and dermatomyositis(DM),and to clarify the associations between these data and clinical variables of IIM.METHODS:Totally 57 PM,41 DM patients and 62 controls were enrolled in this cross-sectional,observational,case-control study.All study participants underwent Pentacam evaluation.Laboratory investigations consisted of different antibody assays,while extramuscular clinical assessments included Raynaud’s phenomenon,dysphagia,interstitial lung disease,arthritis/arthralgia,and weight loss.Objective signs and subjective symptoms of dry eye disease(DED)were also evaluated.RESULTS:All pachymetric parameters[center,apex,thinnest and maximal keratometry(Kmax)]and corneal volume(CV)of both sides of PM patients proved to be significantly lower.Some pachymetric data were also noticed as significantly decreased compared to those of controls.Several significant differences were traced between anterior segment values and extramuscular manifestations of myositis,largely in case of arthritis/arthralgia and weight loss,whereas associations between anterior segment parameters and antibodies were weak.Objective clinical tests of DED were also significantly decreased in IIM patients.CONCLUSION:The results suggest that all IIM patients have thinner corneas compared with those of controls,and decreased corneal parameters are significantly associated with the occurrence of some extramuscular manifestations.In addition,IIM patients tend to develop objective signs of DED. 展开更多
