Long-term secular trends in dermatomyositis and polymyositis mortality in the USA from 1981 to 2020 according to underlying and multiple cause of death mortality data. Arthritis Res Ther 2023; 25:16. [PMID: 36721230 PMCID: PMC9887902 DOI: 10.1186/s13075-022-02963-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 11/30/2022] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND People with dermatomyositis (DM) or polymyositis (PM) often die from cancer, pulmonary, cardiac complications, or infections. In such cases, DM or PM might not be designated as the underlying cause of death (UCD) for mortality tabulation. In this study, we investigated DM/PM mortality trends in the USA from 1981 to 2020 with respect to UCD and multiple causes of death (MCD) data. METHODS We used the MCD data to identify all deaths with DM or PM mentioned anywhere on the death certificate and as the UCD in the USA from 1981-1982 to 2019-2020. We calculated age-adjusted mortality rates (AAMRs) and annual percentage changes (APCs) based on joinpoint regression analysis. RESULTS We identified 12,249 (3985 with DM and 7097 with PM) and 23,608 (8264 with DM and 15,344 with PM) people who died between 1981 and 2020 according to the UCD and MCD data, respectively. For DM, the APC was - 6.7% (from 1981-1982 to 1985-1986), - 0.1% (from 1985-1986 to 2003-2004), and - 1.9% (from 2003-2004 to 2019-2020) according UCD and was - 1.2% (from 1981-1982 to 2003-2004), - 2.5% (from 2003-2004 to 2015-2016), and 2.8% (from 2015-2016 to 2019-2020) according MCD. For PM, the APC was 1.9% (from 1981-1982 to 1989-1990), - 2.3% (from 1989-1990 to 2005-2006), and - 5.2% (from 2005-2006 to 2019-2020) according UCD and was 1.3% (from 1981-1982 to 1991-1992) and - 4.1% (from 1991-1992 to 2019-2020) according MCD. CONCLUSION We identified two times as many DM/PM deaths using the MCD as those identified using the UCD. Similar downward DM/PM mortality trends were noted according to UCD and MCD. However, the year of significant decline in PM mortality was about 10 years earlier according to MCD than those according to UCD.

Assessment and management of the heightened risk for atherosclerotic cardiovascular events in patients with lupus erythematosus or dermatomyositis. Int J Womens Dermatol 2021; 7:560-575. [PMID: 35024413 PMCID: PMC8721062 DOI: 10.1016/j.ijwd.2021.08.015] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Revised: 08/27/2021] [Accepted: 08/31/2021] [Indexed: 01/05/2023] Open
Abstract
For patients with lupus erythematosus (LE) or dermatomyositis (DM), there is an urgent need to address a heightened risk of clinical events, chiefly heart attacks and strokes, caused by atherosclerotic cardiovascular disease (ASCVD). Patients with LE or DM frequently exhibit high levels of conventional risk factors for ASCVD events, particularly dyslipoproteinemia and hypertension; an amplified burden of atherosclerotic plaques; and increased age- and sex-adjusted rates of ASCVD events compared with the general population. The rate of ASCVD events exceeds what would be expected from conventional risk factors, suggesting that disease-specific autoimmune processes exacerbate specific, known pathogenic steps in atherosclerosis. Importantly, despite their heightened risk, patients with LE or DM are often undertreated for known causative agents and exacerbators of ASCVD. Herein, we propose an approach to assess and manage the heightened risk of ASCVD events in patients with LE or DM. Our approach is modeled in large part on established approaches to patients with diabetes mellitus or stage 3 or 4 chronic kidney disease, which are well-studied conditions that also show heightened risk for ASCVD events and have been explicitly incorporated into standard clinical guidelines for ASCVD. Based on the available evidence, we conclude that patients with LE or DM require earlier and more aggressive screening and management of ASCVD. We suggest that physicians consider implementing multipliers of conventional risk calculators to trigger earlier initiation of lifestyle modifications and medical therapies in primary prevention of ASCVD events, employ vascular imaging to quantify the burden of subclinical plaques, and treat to lower lipid targets using statins and newer therapies, such as PCSK9 inhibitors, that decrease ASCVD events in nonautoimmune cohorts. More clinical vigilance is needed regarding surveillance, prevention, risk modification, and treatment of dyslipidemias, hypertension, and smoking in patients with LE or DM. All of these goals are achievable.

Abstract
To assess whether polymyositis is associated with more complications and higher healthcare utilization after total knee or hip arthroplasty (TKA/THA). Using the 1998-2014 U.S. National Inpatient Sample data, we performed multivariable-adjusted logistic regression analyses to assess the association of polymyositis with in-hospital complications (implant infection, revision, transfusion, mortality) and healthcare utilization (hospital charges, length of hospital stay, discharge to non-home setting), controlling for important covariates and confounders. Sensitivity analyses additionally adjusted the main models for hospital location/teaching status, bed size, and region. Of the 4,116,485 THAs and 8,127,282 TKAs, 853 people with polymyositis had THAs (0.02%) and 1038 had TKAs (0.01%). In multivariable-adjusted analyses, compared to people without polymyositis, people with polymyositis had similar odds of hospital charges above the median, hospital stay > 3 days, and discharge to non-home setting post-TKA and post-THA. Polymyositis was associated with significantly lower odds ratio (OR; 95% confidence interval [CI]) of revision and mortality post-THA, 0.44 (0.36, 0.55) and 0.63 (0.48, 0.84), but not post-TKA, 2.98 (0.47, 18.95) and 4.40 (0.61, 31.64), respectively. Findings from the main analyses were confirmed in the sensitivity analyses. People with polymyositis had no increase in healthcare utilization post-TKA/THA. A lower revision rate and mortality post-THA in people with polymyositis need further confirmation. Study findings should reassure the key stakeholders about the benefits of TKA/THA, including people with polymyositis.

Abstract
BACKGROUND Factors associated with survival in patients with idiopathic inflammatory myopathies are heterogeneous. OBJECTIVE This study aimed to describe clinical and prognostic factors associated with survival in Mexican patients with idiopathic inflammatory myopathies. METHODS Patients with dermatomyositis (DM) and polymyositis (PM) seen at a tertiary care center from 1985 to 2012 were included. Demographic and clinical characteristics, comorbidities, treatment, and the time to death were recorded. Patients with juvenile DM were excluded. Univariate and multivariate analyses were performed to identify factors associated with mortality. RESULTS A total of 264 patients with DM and 69 patients with PM were studied. Patients with DM had lower levels of creatine phosphokinase, less cumulative dose of prednisone, higher frequency of dysphagia, and no difference in frequency of interstitial lung disease compared with patients with PM. Patients with DM had lower survival during the first 4 years of disease (80%; 95% confidence interval [CI], 0.74-0.85 vs 89%; 95% CI, 0.78-0.95; P = 0.03 log-rank). Respiratory failure due to pulmonary infection was the main cause of death in patients with DM; miscellaneous causes were responsible for death in patients with PM. Muscular strength (hazard ratio [HR], 0.48; 95% CI, 0.27-0.83; P = 0.01), platelet count (HR, 0.98; 95% CI, 0.98-0.99; P = 0.002), as well as ever use of methotrexate (HR, 0.21; 95% CI, 0.07-0.65; P = 0.007) and azathioprine (HR, 0.21; 95% CI, 0.06-0.68; P = 0.009) were independent factors associated with mortality in patients with DM; in those with PM, only cancer was associated (HR, 8.0; 95% CI, 1.4-43.9; P = 0.01). CONCLUSIONS Patients with DM had lower survival during the first 4 years of disease than patients with PM. Factors associated with mortality differed in both groups.

Intervention to Improve Quality of life for African-AmericaN lupus patients (IQAN): study protocol for a randomized controlled trial of a unique a la carte intervention approach to self-management of lupus in African Americans. BMC Health Serv Res 2016; 16:339. [PMID: 27485509 PMCID: PMC4971708 DOI: 10.1186/s12913-016-1580-6] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2015] [Accepted: 07/22/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Systemic Lupus Erythematosus (lupus) is a chronic autoimmune disease that can impact any organ system and result in life-threatening complications. African-Americans are at increased risk for morbidity and mortality from lupus. Self-management programs have demonstrated significant improvements in health distress, self-reported global health, and activity limitation among people with lupus. Despite benefits, arthritis self-management education has reached only a limited number of people. Self-selection of program could improve such trends. The aim of the current study is to test a novel intervention to improve quality of life, decrease indicators of depression, and reduce perceived and biological indicators of stress in African-American lupus patients in South Carolina. METHODS/DESIGN In a three armed randomized, wait list controlled trial, we will evaluate the effectiveness of a patient-centered 'a-la-carte' approach that offers subjects a variety of modes of interaction from which they can choose as many or few as they wish, compared to a 'set menu' approach and usual care. This unique 'a-la-carte' self-management program will be offered to 50 African-American lupus patients participating in a longitudinal observational web-based SLE Database at the Medical University of South Carolina. Each individualized intervention plan will include 1-4 options, including a mail-delivered arthritis kit, addition and access to an online message board, participation in a support group, and enrollment in a local self-management program. A 'set menu' control group of 50 lupus patients will be offered a standardized chronic disease self-management program only, and a control group of 50 lupus patients will receive usual care. Outcomes will include changes in (a) health behaviors, (b) health status, (c) health care utilization, and (d) biological markers (urinary catecholamines). DISCUSSION Such a culturally sensitive educational intervention which includes self-selection of program components has the potential to improve disparate trends in quality of life, disease activity, depression, and stress among African-American lupus patients, as better outcomes have been documented when participants are able to choose/dictate the content and/or pace of the respective treatment/intervention program. Since there is currently no "gold standard" self-management program specifically for lupus, this project may have a considerable impact on future research and policy decisions.

Abstract
INTRODUCTION The aims of this present study were firstly to assess the outcome, including functional course, in anti-Jo1 positive patients with antisynthetase syndrome (ASS), and secondly to determine predictive parameters of poor outcome in these patients. METHODS The medical records of 86 consecutive anti-Jo1 patients with ASS were reviewed in 4 academic centers. RESULTS 13 patients (15.1%) achieved remission of ASS, whereas 55 (63.9%) improved and 18 (20.9%) deteriorated in their clinical status. Both steroid and cytotoxic drugs could be discontinued in only 4.7% of patients. ASS was associated with decreased quality of life at long-term follow-up: only 69.2% of patients considered to be in remission experienced a return to previous normal activities; and 24.7% of other patients with non-remitting ASS still had a marked reduction of activities (as shown by the disability scale of the Health Assessment Questionnaire). Decreased quality of life was further due to calcinosis cutis (8.1%) and adverse effects of steroid therapy (36%). Factors associated with ASS deterioration were older age, pulmonary and esophageal involvement, calcinosis cutis and cancer. Higher anti-Jo1 levels were further associated with disease severity in ASS patients. CONCLUSIONS The present study shows high morbidity related to ASS. Furthermore, we suggest that patients with predictive factors of ASS deterioration may require more aggressive therapy. Our findings also suggest that in anti-Jo1 patients with severe esophageal manifestations, combined high dose steroids and intravenous immunoglobulins might be proposed as the first line therapy. Finally, as cancer occurred in 14% of anti-Jo1 patients, our findings underscore that the search for cancer should be performed in these patients.

Abstract
Before the use of corticosteroids, the prognosis for polymyositis/dermatomyositis (PM/DM) was extremely poor. To date, although overall prognosis appears to be better, PM and DM are still considered to be associated with increased morbidity, primarily related to severe muscle weakness and visceral involvement. Recent series underline that only 20% to 40% of treated patients will achieve PM/DM remission, whereas 60% to 80% will experience a polycyclic or chronic, continuous course of the disease. PM/DM further continues to have a great impact on life in medium- and long-term follow-up, as up to 80% of treated patients are still disabled (using Health Assessment Questionnaire scores). The overall mortality ratio in PM/DM patients also remains threefold higher compared with the general population, with cancer, lung, and cardiac complications and infections being the most common causes of deaths. Predictive factors for a poor prognosis in PM/DM patients are older age, involvement of lung and cardiac systems, dysphagia, cancer, and serum myositis-specific antibodies (including coexistent presence of anti-Ro52 and anti-Jo1 antibodies, anti-signal recognition particle antibody, anti-155/140, and anti-CADM-140 antibodies).

Abstract
BACKGROUND AND OBJECTIVE Polymyositis (PM) and dermatomyositis (DM) are idiopathic inflammatory myopathies that are associated with a variety of clinical manifestations including pulmonary complications. The objective of the present study was to determine the causes of deaths in this complex patient population. METHODS A computer-assisted search of medical and autopsy records identified a total of 39 patients with either PM or DM who underwent an autopsy at the Mayo Clinic (Rochester, MN, USA) over a 29-year period from 1 January 1981 to 31 December 2009. The immediate causes of death along with contributing causes were determined by reviewing all available clinical data and autopsy findings. We also analysed the discordance between ante-mortem clinical diagnoses provided by clinicians and the final diagnosis by the post-mortem analysis. RESULTS Respiratory (33%), infectious (28%) and cardiovascular diseases (26%) accounted for the majority of immediate causes of death. Acute exacerbation of chronic interstitial lung disease (15%) and bronchopneumonia (15%) were the most common specific causes. Immediate cause of death was not suspected in nearly one third of cases and included bronchopneumonia, sepsis, acute myocardial infarction, aspiration pneumonia, pulmonary embolism, aortic stenosis, mycotic aneurysm rupture and acute haemoperitoneum. CONCLUSIONS We conclude that pulmonary injury is the immediate cause of death in one third of patients with PM/DM; acute exacerbation of chronic interstitial lung disease and bronchopneumonia were the most common specific causes. Immediate cause of death was not established ante-mortem in nearly one third of cases, and some of these causes were treatable.

Abstract
OBJECTIVES The objective of this study was to assess the incidence and common types of concomitant malignancies and to define predictive factors of death in Korean patients with idiopathic inflammatory myopathy (IIM). METHODS From January 1989 to May 2011, 162 patients were diagnosed with IIM at a university hospital in Korea. The medical records were retrospectively reviewed. The clinical findings of the patients were compared for malignancy, and the prognostic factors predicting death were analyzed. RESULTS Malignancies were found in 17 patients (10.5 %), all of whom had a significantly lower frequency of interstitial lung disease (ILD) and an older age at onset. The main causes of death were ILD and malignancy. Older age at diagnosis, presence of malignancy, rapidly progressive ILD and minimal creatinine phosphokinase (CPK) elevation were independent risk factors for death. CONCLUSIONS Malignancy was one of the most serious risk factor for death in our patients with IIM. Early discovery of malignancy is important, and an extensive investigation for common malignancies in each region should be done at diagnosis and for a minimum of 2 years thereafter. As minimally elevated CPK levels in ILD patients may be associated with fatal ILD, an early evaluation and a more aggressive treatment of ILD should be considered in these patients.

Abstract
We report a case of dermatomyositis associated with rheumatoid arthritis, Hashimoto thyroiditis, and diabetes mellitus responsive only to combination of rituximab with mycophenolate. A 42-year-old woman presented with proximal muscle weakness, myalgias, fever, night sweats, and shortness of breath. Creatinine kinase was 8155 IU/L, and muscle biopsy was diagnostic of dermatomyositis. She was started on glucocorticoids; her systemic symptoms improved, but her muscle weakness persisted. She was serially treated with intravenous immunoglobulin, azathioprine, and mycophenolate mofetil without improvement in her weakness. She responded dramatically to combination therapy with rituximab and mycophenolate, with improvement in strength and normalization of creatinine kinase. She has been well controlled on rituximab infusion every 6 months and maintenance mycophenolate mofetil.

Abstract
Juvenile dermatomyositis is a rare disorder, but remains the most commonly occurring chronic inflammatory myopathy among children. Other than the proximal muscles and skin, which are routinely affected, vasculopathy may affect other viscera and can be multisystemic. A redefinition of the diagnostic criteria is currently underway and is likely to lead to other clinical signs and to sensitive and non-invasive examinations such as MRI. The impact of juvenile dermatomyositis on health and quality of life remains significant despite systemic corticosteroid therapy and immunosuppressor treatment, which have considerably improved the prognosis. Numerous predictors for favourable and pejorative evolution have been identified. The standardisation and the generalisation of clinical assessment tools will make it possible to carry out the clinical trials required to determine the relevance of the new therapeutic options available for children.

BMC Public Health 2010; 10:597. [PMID: 20937106 PMCID: PMC3091559 DOI: 10.1186/1471-2458-10-597] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2010] [Accepted: 10/11/2010] [Indexed: 01/08/2023] Open
Abstract
BACKGROUND Dermatomyositis (DM) and polymyositis (PM) are rare systemic autoimmune rheumatic diseases with high fatality rates. There have been few population-based mortality studies of dermatomyositis and polymyositis in the world, and none have been conducted in Brazil. The objective of the present study was to employ multiple-cause-of-death methodology in the analysis of trends in mortality related to dermatomyositis and polymyositis in the state of São Paulo, Brazil, between 1985 and 2007. METHODS We analyzed mortality data from the São Paulo State Data Analysis System, selecting all death certificates on which DM or PM was listed as a cause of death. The variables sex, age and underlying, associated or total mentions of causes of death were studied using mortality rates, proportions and historical trends. Statistical analysis were performed by chi-square and H Kruskal-Wallis tests, variance analysis and linear regression. A p value less than 0.05 was regarded as significant. RESULTS Over a 23-year period, there were 318 DM-related deaths and 316 PM-related deaths. Overall, DM/PM was designated as an underlying cause in 55.2% and as an associated cause in 44.8%; among 634 total deaths females accounted for 71.5%. During the study period, age- and gender-adjusted DM mortality rates did not change significantly, although PM as an underlying cause and total mentions of PM trended lower (p < 0.05). The mean ages at death were 47.76 ± 20.81 years for DM and 54.24 ± 17.94 years for PM (p = 0.0003). For DM/PM, respectively, as underlying causes, the principal associated causes of death were as follows: pneumonia (in 43.8%/33.5%); respiratory failure (in 34.4%/32.3%); interstitial pulmonary diseases and other pulmonary conditions (in 28.9%/17.6%); and septicemia (in 22.8%/15.9%). For DM/PM, respectively, as associated causes, the following were the principal underlying causes of death: respiratory disorders (in 28.3%/26.0%); circulatory disorders (in 17.4%/20.5%); neoplasms (in 16.7%/13.7%); infectious and parasitic diseases (in 11.6%/9.6%); and gastrointestinal disorders (in 8.0%/4.8%). Of the 318 DM-related deaths, 36 involved neoplasms, compared with 20 of the 316 PM-related deaths (p = 0.03). CONCLUSIONS Our study using multiple cause of deaths found that DM/PM were identified as the underlying cause of death in only 55.2% of the deaths, indicating that both diseases were underestimated in the primary mortality statistics. We observed a predominance of deaths in women and in older individuals, as well as a trend toward stability in the mortality rates. We have confirmed that the risk of death is greater when either disease is accompanied by neoplasm, albeit to lesser degree in individuals with PM. The investigation of the underlying and associated causes of death related to DM/PM broaden the knowledge of the natural history of both diseases and could help integrate mortality data for use in the evaluation of control measures for DM/PM.

Abstract
Dermatomyositis (DM) is an idiopathic inflammatory myopathy with bimodal onset age distribution. The age of onset is between 5-18 yr in juvenile DM and 45-64 yr in adult DM. DM has a distinct clinical manifestation characterized by proximal muscle weakness, skin rash, extramuscular manifestations (joint contracture, dysphagia, cardiac disturbances, pulmonary symptoms, subcutaneous calcifications), and associated disorders (connective tissue disease, systemic autoimmune diseases, malignancy). The pathogenesis of juvenile and adult DM is presumably similar but there are important differences in some of the clinical manifestations, associated disorders, and outcomes. In this study, we investigated the clinical characteristics and outcomes of 16 patients with juvenile DM and 48 with adult DM. This study recognizes distinctive characteristics of juvenile DM such as higher frequency of neck muscle involvement, subcutaneous calcifications, and better outcomes.

Abstract
Idiopathic inflammatory myopathies (IIMs) are systemic autoimmune diseases characterized by chronic muscle inflammation resulting in progressive weakness and frequent involvement of internal organs, mainly the pulmonary, gastrointestinal and cardiac systems which considerably contribute to the morbidity and mortality of the IIMs. Aim of this study was to present clinical characteristics, disease course, frequency of relapses and survival in patients with juvenile dermatomyositis (DM). A national registry of patients with juvenile IIMs was elaborated by the authors in Hungary. We have summarized data of the register according to signs and symptoms, disease course, frequency of relapses and survival of patients with juvenile IIM. Analysis was performed using data of 44 patients with juvenile DM diagnosed between 1976 and 2004 according to Bohan and Peter's criteria. Survival probability was calculated by Kaplan-Meier method. Data of patients with juvenile DM were compared with data of 66 patients with adult DM. The most frequent cutaneous features were facial erythema and heliotrope rash. Extramuscular and extraskeletal manifestations of the disease were more frequent in adult patients. The most common extramuscular feature was arthralgia in both groups of patients with juvenile or adult DM. Cardiac manifestation of the disease was not observed in juvenile patients. Respiratory muscle involvement and interstitial lung disease (ILD) were more frequent among adult DM patients than cardiac manifestation of the myositis. In view of the disease course, the authors found that frequency of polycyclic and monophasic subtypes of the disease were mainly similar. The hazard of relapse was found higher during the first year after the remission. None of the juvenile patients died. Among adult patients four disease-specific deaths occurred. There was no correlation between relapse free survival and initial therapeutic regimen. Many of our patients had polycyclic or chronic disease. As relapses can occur after a prolonged disease-free interval, patients should be followed up for at least 2 years. Although we found favourable survival probability, further investigations are needed to assess functional outcome.

Abstract
INTRODUCTION The idiopathic inflammatory myopathies are systemic autoimmune diseases characterized by chronic muscle inflammation resulting progressive weakness and frequent involvement of internal organs, mainly the pulmonary, gastrointestinal and cardiac systems. OBJECTIVE To present clinical characteristics, disease course, frequency of relapses and survival of 79 patients with juvenile or adult dermatomyositis. METHODS A national registry of patients with juvenile dermatomyositis was elaborated by the authors in Hungary. The authors summarize data of the register such as signs and symptoms, disease course, frequency of relapses and survival of patients with juvenile dermatomyositis. Analysis was performed using data of 44 patients diagnosed between 1976 and 2004 according to Bohan and Peter's criteria. Survival probability was calculated by Kaplan-Meier method. Data of patients with juvenile dermatomyositis were compared with data of 35 patients with adult dermatomyositis. RESULTS In view of the disease course, the authors found that more than the half of patients have monophasic disease, while one third of them suffered from polycyclic disease. The risk of the relapse was found to be higher during the first year after the remission. None of the juvenile patients died. Among adult patients, 4 disease-specific deaths occurred. DISCUSSION There was no correlation between relapse free survival and initial therapeutic regimen. Many of the patients had polycyclic or chronic disease. As relapses can occur after a prolonged disease-free interval, patients should be followed up for at least 2 years. Despite favourable survival probability, further investigations are needed to assess functional outcome.

Abstract
The objective of this study was to assess the long-term outcome of polymyositis (PM) and dermatomyositis (DM) and the factors predictive of this outcome in a nationwide series in Finland. One hundred and seventy-six patients with PM and 72 patients with DM diagnosed in Finland in 1969-1985 were selected from the national hospital discharge register according to the diagnostic criteria of Bohan and Peter and followed up until death or till the end of August 1995. Gender, age, delay of therapy, serum creatine kinase, erythrocyte sedimentation rate, initial dose of corticosteroids and duration of cytostatic therapy were assessed as factors prognostic of death. The 5-year survival rate for PM was 75% [95% confidence interval (CI): 68-81%] and that for DM 63% (50-73%), and the respective 10-year survival rates were 55% (47-62%) and 53% (41-64%). The median survival for polymyositis was 11.0 years (95% CI: 9.5-13.3) and that for DM 12.3 years (5.5-20.7). The standardized mortality ratio for the combined group of PM and DM showed approximately threefold mortality compared to the general population. Compared to PM patients, the subjects with DM had a 1.47-fold (95% CI: 0.99-2.12) age- and sex-adjusted risk of mortality. Except for age in both groups and the delay in diagnosis in the PM group, no other individual factor reached significance as a predictor of death. However, cancer had a hazard ratio (HR) of 2.16 for death (95% CI: 0.95-4.50) in the DM group and 1.99 (95% CI: 1.01-3.94) in the PM group. A comparison of the causes of death in the PM and DM groups showed that the patients with DM had a greater risk of dying from cancer (age-adjusted HR 5.11, 95% CI: 2.31-11.3). According to this nationwide analysis of survival and its prognostic factors in patients with PM and DM, the latter group had an increased age-adjusted risk for mortality compared to the former. The difference seems to be mostly explained by the fact that the patients with DM had a higher risk of dying from cancer.

Abstract
OBJECTIVE To test the hypothesis that B cells play a role in the pathophysiology of dermatomyositis (DM) by examining the effect of B cell depletion in patients with symptomatic DM. Patients were treated with rituximab, a CD20+ B cell-depleting monoclonal antibody. METHODS This was an open-label uncontrolled pilot trial in 7 adult patients with DM, 6 of whom had longstanding illness that was responding inadequately to a number of currently available immunosuppressive agents. All patients received 4 intravenous infusions of rituximab given at weekly intervals. Patients were followed up for up to 1 year without further treatment with rituximab. One patient was lost to followup. The principal efficacy outcome was muscle strength, measured by quantitative dynomometry. RESULTS All 6 evaluable patients exhibited major clinical improvement, with muscle strength increasing over baseline by 36-113%. Maximal improvements in muscle strength occurred as early as 12 weeks after the initial infusion of rituximab. CD20+ B cells were effectively depleted in all patients by 12 weeks. Four patients experienced a return of symptoms that coincided with the return of B cells before the 52-week end point. Two patients maintained their increased muscle strength at 52 weeks, and 1 of these patients maintained this strength even after the return of B cells. Other symptoms of DM, including rash, alopecia, and reduced forced vital capacity, improved markedly in patients with these symptoms. Rituximab was well tolerated, with no treatment-related severe or serious adverse events during the observation period of this study. CONCLUSION This small open-label study of DM patients treated with rituximab provided sufficiently encouraging results to justify a more formal evaluation of the value of B cell depletion therapy in the treatment of DM.

Abstract
The immune system undergoes continuous morphologic and functional changes throughout the years, and it is now believed that the immune response has its peak function in puberty and gradually decreases with age (immunosenescence). Recent studies in healthy octogenarian patients suggest that the immune system, instead of suffering a generalized deterioration, undergoes a remodelling/readjustment of its major functions. Increase in two contrasting phenomena coexist in immunosenescence: on the one hand, a decrease in the capacity of the immune response and, on the other hand autoantibody production. The possible consequences of this progressive 'ageing' of the immune system are the increase in autoimmune phenomena, incidence of neoplasia and predisposition to infections. The study of autoimmune manifestations in elderly populations should be considered a priority for future medical research because of increasing life expectancy, especially in developed countries. This review analyses the main immune disorders associated with immunosenescence, the prevalence and clinical significance of autoantibodies in the elderly and the clinical expression of the main autoimmune diseases in older patients.

Abstract
Electrodiagnostic studies are an important adjunct to the clinical examination of a patient with a suspected myopathy; however, the clinical examination is crucial in making an accurate diagnosis, because electrodiagnostic studies have only a limited role in delineating with certainty the underlying myopathic disorder. Hereditary and acquired myopathies are reviewed in this article, with particular emphasis on distinguishing clinical and electrodiagnostic features. The hereditary myopathies that are discussed include the muscular dystrophies and the congenital distal mitochondrial, and metabolic myopathies. Acquired myopathies, including inflammatory, endocrine, and toxic myopathies, as well as those associated with systemic illness, are briefly reviewed.

Abstract
Muscle disease symptoms and myopathies are not uncommon in the elderly. Inflammatory and noninflammatory myopathies lead to proximal extremity or axial weakness and are superimposed on the intrinsic changes that occur in muscle with aging (sarcopenia). This article surveys the more common myopathies in the elderly based on a review of the process of sarcopenia, and how these age-related changes in muscle structure and function affect the results of the standard assessments of muscle disease in the elderly.

Abstract
In a retrospective study of 79 consecutive patients, we evaluated characteristics of polymyositis (PM) and dermatomyositis (DM) and compared clinical presentation, biochemical findings, histologic changes, evolution, complications, and mortality rate of elderly patients (aged > or = 65 yr) and younger patients (aged < or = 64 yr) at the onset of PM/DM. We found a high prevalence of PM/DM in elderly patients: 23 patients (29%) were aged 65 years or over. We also found that esophageal involvement (34.8% versus 16.1%, respectively) and bacterial pneumonia related to both ventilatory insufficiency and esophageal impairment (21.7% versus 5.4%, respectively) were more common in elderly patients compared with younger patients, resulting in increased morbidity and mortality rates. Moreover, malignancy frequency was higher in elderly patients compared with younger patients (47.8% versus 9.1%, respectively, p = 0.0001), particularly patients with DM (10/11). Fifty percent of malignancies were colon malignancies in elderly patients. Erythrocyte sedimentation rate, C-reactive protein, fibrinogen, and ferritin levels were also higher in the elderly patient group compared with the younger group, and the presence of serum hypoprotidemia, hypoalbuminemia, and anemia was more frequent. Finally, PM/DM complete remission was less frequent (13.6% versus 41.1%) and the mortality rate (47.8% versus 7.3%) was higher in elderly patients than in younger patients. The main causes of death in elderly patients were bacterial pneumonia, due to ventilatory insufficiency and esophageal impairment, and malignancies. Our findings therefore indicate that PM/DM-related esophageal and lung involvement should be systematically searched for in elderly patients. Esophageal manometry and pulmonary function tests should become an integral part of initial evaluation in elderly patients for early detection of impairment. Moreover, as we observed a marked overrepresentation of colon cancer in elderly patients with DM, we suggest that the search for malignancies in elderly patients with DM should include lower gastrointestinal tract investigations.

Abstract
Dermatomyositis, polymyositis, and inclusion body myositis are the major categories of idiopathic inflammatory myopathy. These inflammatory myopathies are distinct clinically, histologically, and pathogenically. Features of dermatomyositis and polymyositis can overlap with those of other autoimmune connective tissue diseases. In this article, the authors review the characteristic features of these myopathies, update the recent developments in this area, and provide a framework for treatment.

Abstract
OBJECTIVE To review mortality data in published studies of various rheumatic diseases. METHODS A MEDLINE search of the literature on the rheumatic diseases, including osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, systemic lupus erythematosus, scleroderma, polymyositis, and vasculitis. RESULTS Mortality rates higher than expected have been reported in most rheumatic conditions, considerably higher for inflammatory rheumatic diseases. The mortality rates in patients with systemic lupus erythematosus, scleroderma, polymyositis, and vasculitis are often comparable to mortality rates seen in patients with neoplastic or cardiovascular diseases, although the causes of death often are not identified as the rheumatic disease. CONCLUSION Mortality has been found to be predicted in most instances by more severe clinical status, and therefore death should not be considered as "unrelated" to the rheumatic disease. These observations may have important implications for clinical care and health policies regarding patients with rheumatic diseases.

Abstract
In summary, the child who develops the symptoms of the specific rash, proximal muscle weakness, or fatigue should seek medical care promptly. With the advances in physical and medical therapy, many of the consequences of the disease can now be ameliorated. Data suggest that JDMS and PM may each have a different pathophysiology, but more evidence is needed. The next few years will be exciting as there is a national effort by an increased number of investigators to determine the epidemiologic and genetic factors that influence JDMS disease susceptibility and severity.

Abstract
The purpose of this article is to illustrate with a case study the process through which a patient with polymyositis taking part in an occupational therapy program achieved functional improvement in spite of persistent muscle weakness. Although the focus is on the occupational therapy program, close monitoring of patient improvement or regression by the total rehabilitation team was essential in order to adjust the patient's weekly activity level for maximum benefit.

Abstract
OBJECTIVES To determine possible similarities and differences in clinical and laboratory features and treatment response between patients in Singapore with polymyositis (PM) and dermatomyositis (DM) and reported series. METHODS Case records of adult patients (16 years old and above) referred to the 3 main electromyographic (EMG) laboratories in Singapore between 1 June 1986 and 31 May 1991 were reviewed if the referring diagnosis was myositis or myopathy for investigation. A computer search for adult patients with a diagnosis of PM/DM (ICD codes 710.3, 710.4, 517.8) who attended the main rheumatology and neurology centre during this period was also carried out. The criteria for PM/DM proposed by Bohan and Peter was adopted. RESULTS The incidence of PM/DM was 7.7 cases per million population per year. There were 35 PM and 40 DM cases with a median age at diagnosis of 50.7 years (SD: 16.7) and significantly more females in the PM group (p < 0.05). At presentation, 86.7% had proximal myopathy, 34.7% had arthralgia/arthritis and 18.7% had cutaneous vasculitis. The creatine kinase level was elevated in 89.3% of patients and positive EMG and muscle biopsy in 79.4% and 76.4% respectively. Systemic lupus erythematosus was the commonest associated connective tissue disease. The percentage of patients with malignancy was higher in DM compared with PM (p < 0.01) and they were significantly older (mean age 61.8 years) (p < 0.001). Patients who achieved remission were significantly younger (mean age 46.4 years, p < 0.05). The overall mortality rate was 26.7% with infection and malignancy as the main causes of death. CONCLUSION The results of the study suggest ethnicity does not influence the expression of PM/DM in view of the considerable similarities in frequency and clinical expression of disease in the population studied compared with series from other countries.

Abstract
By sending questionnaires to the major dermatological clinics in Japan, we examined the outcome and causes of death in 182 cases of dermatomyositis (DM) observed between 1983 and 1987. The mortality rate in adults was 26.7%. Associated malignancy occurred in 47 cases (25.8% of adults), and 16 of them died of neoplasms. In contrast to 43 carcinomas, only 1 patient died of lymphoma. Associated interstitial pneumonitis (IP) appeared in 31 cases. IP started simultaneously or within 6 months after the diagnosis of DM in the majority of these cases. Of the 13 fatal cases due to IP, 8 died of respiratory failure within two months of the onset of lung disease. In the malignancy group, periungual erythema was noted in a higher proportion. Raynaud's phenomenon was more frequently noted in the IP group. DM overlapped with other collagen diseases in 14 cases.

Abstract
A retrospective study of 25 patients with polymyositis-dermatomyositis (PM-DM) is analyzed with special attention to the effects of therapy and follow-up. All patients (100%) complained of muscle weakness and 68% of these demonstrated typical skin changes of DM. All patients, except 2, received corticosteroids at the onset of the disease, 23 were treated with azathioprine, 7 received cyclophosphamide, 4 methotrexate, and 1 had total body irradiation. Among the patients adequately treated with azathioprine, 75% had a good response, but 5 patients did not improve. Cyclophosphamide was used subsequently in 2, with a satisfactory response in 1. Another patient had a striking response to oral methotrexate, and total body irradiation helped to improve another patient. Although high dose corticosteroids were the preferred starting medication for the treatment of PM-DM, it is important to detect those patients who do not respond adequately and/or develop side effects. In these circumstances, the prompt use of immunosuppressive agents appears justified.

Abstract
Children with PM/DM differ in many respects from adults with PM/DM. The most characteristic and distinctive feature is the presence of a widespread vasculopathy. Although the pathogenesis is unknown, roles for both humoral and cell-mediated immunity have been proposed. Most intriguing is the evidence for a viral agent that is capable of precipitating an ongoing, immunologically mediated reaction damaging muscles and endothelial cells. Much remains to be discovered, however, regarding the pathogenesis of this disease.

Abstract
Dermatomyositis and polymyositis are related disorders of unknown cause in which immunologic changes may be important. They sometimes overlap with other collagen vascular diseases, and not infrequently are associated with malignancy. The clinical features of the adult and juvenile forms of the disorder and the visceral manifestations of DM-PM are outlined, along with enzymatic, electromyographic, and histologic aids to diagnosis. While the cutaneous lesions often are resistant to treatment, systemic involvement may respond to corticosteroids or to immunosuppressive drugs. Treatment definitely alters the prognosis in cases not associated with malignancy.

Abstract
Myositis in childhood is characterized by elevated serum levels of muscle-derived enzymes, proximal symmetrical muscle weakness, abnormal EMG findings, and a muscle biopsy, which frequently documents an inflammatory process. In the pediatric age group, JDMS, which has characteristic cutaneous involvement in addition to myositis, is much more common than PM and is more common among female patients. With the use of steroids, mortality has been reduced from 33 per cent to 7 per cent. The development of calcifications can be the most debilitating consequence of JDMS. It is our premise that JDMS is a distinct disease entity and that the increase in HLA-B8 and DR3 in JDMS suggests that genetic background may predispose to disease development. There are conflicting data concerning immunologic abnormalities in JDMS, but there appears to be impairment of natural killing and evidence of complement activation. Results of tests for ANA frequently are positive in JDMS, but Jo-1 antibody, found in some adults with PM, has not been found in JDMS. Most newly diagnosed JDMS patients have antibodies to coxsackie B that may be related to the pathogenesis of this disease. Specific pathologic findings of endothelial cells containing reticulotubular inclusions are associated with small vessel occlusion, subsequent obliteration, and increased factor VIII levels in clinically active disease. In addition to physical therapy, steroids are used most frequently, but other immunosuppressive agents and plasmapheresis have been tried in severely ill children. Rigorous evaluation of the efficacy of these modalities is needed.

Abstract
The inflammatory myopathies have diverse clinical and pathological features and multiple etiologies. Some are confined to a single muscle or group of muscles (e.g., orbital myositis and localized nodular myositis) while others are diffuse. Infective forms may be due to viral, bacterial, fungal, protozoal, or parasitic organisms. Viruses may cause acute self-limited forms of myositis and have been isolated from muscle in some cases of acute rhabdomyolysis and inclusion body myositis. They have also been implicated in some cases of congenital myopathy and in polymyositis and dermatomyositis, but there is no evidence of viral invasion of muscle in these conditions. In polymyositis and dermatomyositis there are derangements in humoral and cellular immune function, and recent evidence suggests an underlying disturbance of immunoregulation. The roles of genetic factors, drugs, and Toxoplasma infection have been under scrutiny. There is increasing recognition of immunological and pathological differences in polymyositis and juvenile and adult dermatomyositis, and in cases with associated connective tissue diseases, suggesting different underlying pathogenetic mechanisms. Inclusion body myositis, eosinophilic myositis, and granulomatous myositis can be separated from the other idiopathic inflammatory myopathies because of distinctive clinical and pathological features and this may also reflect different mechanisms of muscle injury. Recent developments in the treatment of the idiopathic inflammatory myopathies include the use of plasmapheresis and total-body irradiation in cases that are resistant to corticosteroids and immunosuppressive drugs.

Abstract
The incidence of systemic lupus erythematosus, based on first hospital discharge diagnosis, in Baltimore, Maryland for the years 1970 through 1977 was determined for individual sex-race groups and the total population. Age-specific incidence rates were consistently highest among black females and lowest among white males: rates for white females exceeded those for black males through age 54, but then declined for ages greater than or equal to 55. Mean age at diagnosis was significantly lower for black females versus white females (35.5 versus 41.7 years, P = 0.005) and for all females versus all males (37.2 versus 44.2 years, P = 0.012). There were no temporal trends noted in yearly age-adjusted incidence rates during the 8-year study period. The overall population incidence of systemic lupus erythematosus was 4.6 per 100,000 per year, representing a twofold increase over a comparable study done in New York City 15 years ago.

Abstract
Mortality from polymyositis and dermatomyositis was estimated between 1968 and 1978. Age-specific average annual mortality rates showed unimodal distributions for all sex-race groups. Synergistic interaction was demonstrated between female sex and nonwhite race, greatest mortality being in nonwhite females through age 74. Increases in annual death rates occurred among both white males and white females during the interval. Finally, the increase in mean age at death among all sex groups correlated with improved prognosis as well as decreased mortality among younger persons over time.
