Síndrome de solapamiento: polimiositis-esclerodermia. Presentación de un caso / Polymyosis-Sclerosis Overlap Syndrome. Case report and review of literature

Introducción: en el síndrome de solapamiento o superposición existen simultáneamente manifestaciones clínicas o serológicas de dos o más enfermedades autoinmunes sistémicas. Afectan al 5 por ciento de la población con predominio en mujeres. Presentación del Caso: hombre de 48 años, sin antecedentes patológicos personales. Acude con dolor en ambas manos, inflamación en las articulaciones metacarpo e interfalángicas proximales, bilateral y simétrica, acompañada de rigidez matinal que duraba casi todo el día desde hace 4 meses. Se le diagnostica artritis reumatoidea y se inicia tratamiento que abandonó. Luego aparece un cuadro que es interpretado como un solapamiento por lo que es ingresado con un cuadro clínico florido. En los exámenes de laboratorio: las transaminasas, la creatín fosfoquinasa, el lactato deshidrogenasa, se encontraban elevadas. Por la clínica y los complementarios se diagnosticó Síndrome de Solapamiento de polimiosistis-esclerodermia. Se comenzó tratamiento con inmunosupesores. El paciente evolucionó desfavorablemente y falleció. Discusión: el diagnóstico de este caso se realizó por las manifestaciones clínicas como fascie esclerodérmica, signo de sal y pimienta, fibrosis de predominio distal en ambas manos, telangiectasias peribucales. Los diagnósticos diferenciales son las enfermedades autoinmunes sistémicas cuando se presentan como cuadros únicos. El tratamiento de primera línea y el pronóstico dependen de las enfermedades que se solapen(AU)

Introduction: In the syndrome of overlap or overlap there are simultaneously clinical or serological manifestations of two or more systemic autoimmune diseases. They affect 5 percent of the population with predominance in women. Case Presentation: A 48-year-old man with no personal pathological history. He came with pain in both hands, inflammation in the metacarpal and interphalangeal proximal joints, bilateral and symmetrical, accompanied by morning stiffness that lasted almost all day for 4 months. He was diagnosed with rheumatoid arthritis and started treatment that he abandoned. Then a picture appears that is interpreted as an overlap so it is entered with a florid clinical picture. In laboratory tests: transaminases, creatine phosphokinase, lactate dehydrogenase, were elevated. Clinical and complementary diagnosis of Polymyosis-Sclerosis Overlap Syndrome was diagnosed. Treatment with immunosupers was started. The patient evolved unfavorably and died. Discussion: The diagnosis of this case was made by clinical manifestations such as sclerodermic fascia, salt and pepper sign, predominantly distal fibrosis in both hands, perioral telangiectasias. Differential diagnoses are systemic autoimmune diseases when presented as single frames. First-line treatment and prognosis depend on overlapping diseases(AU)

Analysis of sexual function of patients with dermatomyositis and polymyositis through self-administered questionnaires: a cross-sectional study / Análise da função sexual de pacientes com dermatomiosite e polimiosite através de questionários autoaplicados: um estudo transversal

Abstract Introduction: To date, there are no descriptions in the literature on gynecologic and sexual function evaluation in female patients with dermatomyositis (DM) and polymyositis (PM). Objective: To assess sexual function in female patients with DM/PM. Patients and methods: This is a monocentric, cross-sectional study in which 23 patients (16 DM and 7 PM), with ages between 18 and 40 years, were compared to 23 healthy women of the same age group. Characteristics on sexual function were obtained by applying the questionnaires Female Sexual Quotient (FSQ) and Female Sexual Function Index (FSFI) validated for the Brazilian Portuguese language. Results: The mean age of patients was comparable to controls (32.7 ± 5.3 vs. 31.7 ± 6.7 years), as well as the distribution of ethnicity and socioeconomic class. As for gynecological characteristics, patients and healthy controls did not differ with respect to age at menarche and percentages of dysmenorrhea, menorrhagia, premenstrual syndrome, pain at mid-cycle, mucocervical secretion, and vaginal discharge. The FSQ score, as well as all domains of the FSFI questionnaire (desire, arousal, lubrication, orgasm and satisfaction), were significantly decreased in patients vs. controls, with 60.9% of patients showing some degree of sexual dysfunction. Conclusions: This was the first study to identify sexual dysfunction in patients with DM/PM. Therefore, a multidisciplinary approach is essential for patients with idiopathic inflammatory myopathies, in order to provide prevention and care for their sexual life, providing a better quality of life, both for patients and their partners.

Resumo Introdução: Até o presente momento, não há descrições na literatura da avaliação ginecológica e da função sexual em pacientes do sexo feminino com dermatomiosite (DM) e polimiosite (PM). Objetivos: Avaliar a função sexual em pacientes do sexo feminino com DM/PM. Casuística e métodos: Estudo transversal unicêntrico em que 23 pacientes (16 DM e sete PM), entre 18 e 40 anos, foram comparadas com 23 mulheres saudáveis, com a mesma faixa etária. As características sobre a função sexual foram obtidas por meio da aplicação dos questionários Female Sexual Quotient (FSQ) e Female Sexual Function Index (FSFI) validados para a língua portuguesa do Brasil. Resultados: A média de idade das pacientes foi comparável à dos controles (32,7 ± 5,3 vs. 31,7 ± 6,7 anos), assim como a distribuição de etnia e da classe socioeconômica. Quanto às características ginecológicas, pacientes e controles saudáveis não apresentaram diferenças em relação à idade na menarca e às porcentagens de dismenorreia, menorragia, síndrome pré-menstrual, dor no meio do ciclo, secreção mucocervical e corrimento vaginal. O escore de pontuação do FSQ, assim como todos os domínios do questionário do FSFI (desejo, excitação, lubrificação, orgasmo e satisfação), estavam significantemente diminuídos nas pacientes comparativamente com os controles, 60,9% das pacientes apresentavam algum grau de disfunção sexual. Conclusões: Este foi o primeiro estudo que identificou disfunção sexual nas pacientes com DM/PM. Assim, uma abordagem multidisciplinar é essencial para pacientes com miopatias inflamatórias idiopáticas para fornecer medidas de prevenção e cuidados para sua vida sexual e propiciar uma melhor qualidade de vida das pacientes e de seus parceiros.

Desfechos da gestação em pacientes com dermatomiosite e polimiosite / Pregnancy outcomes in dermatomyositis and polymyositis patients

Introdução: Há poucos estudos que descrevem a gravidez em pacientes com dermatomiosite/polimiosite. São, em grande parte, limitados a relatos de casos ou estudos com amostras pequenas. Objetivos: Analisar a gestação em uma grande amostra de pacientes com dermatomiosite/polimiosite e os desfechos naquelas que engravidaram durante ou depois do início da doença. Métodos: Foram analisados 98 pacientes do sexo feminino com miopatias inflamatórias idiopáticas (60 com dermatomiosite e 38 com polimiosite). Elas foram entrevistadas entre junho de 2011 e junho de 2012 para coletar seus antecedentes obstétricos e dados demográficos. Resultados: Tinham antecedentes obstétricos 78 (79,6%) das 98 pacientes. Seis pacientes compolimiosite e nove com dermatomiosite engravidaram após o início da doença. O desfecho da gravidez nessas pacientes foi bom, exceto nos seguintes casos: um de reativação da doença, um de retardo do crescimento fetal, um de diabetes mellitus, um de hipertensão arterial, um de hipotireoidismo e dois de aborto (mesma paciente). Além disso, duas pacientes desenvolveram dermatomiosite durante a gravidez e quatro (duas polimiosite e duas dermatomiosite) durante o período pós-parto, com bom controle a seguir com glucocorticoidese terapia imunossupressora. Conclusões: Os eventos obstétricos adversos estiveram relacionados com as intercorrências clínicas e a gravidez não parece levar especificamente a um pior prognóstico na doença (por exemplo: recidiva). Além disso, a dermatomiosite ou polimiosite de início durante a gestaçãoou no período pós-parto apresentou boa evolução depois do tratamento farmacológico. .

Background: Currently, there are few studies that describe pregnancy in dermatomyositis/polymyositis patients, and they are largely limited to case reports or studies with few samples. Objectives: Therefore, we describe the pregnancy in a large sample of patients with dermatomyositis/polymyositis and to analyze the outcomes in those who became pregnant duringor after disease onset. Methods: The present single-center study analyzed 98 female patients with idiopathic inflammatory myopathies (60 dermatomyositis and 38 polymyositis patients). They wereinterviewed to obtain obstetric antecedent and demographic data from June 2011 to June 2012. Results: Seventy-eight (79.6%) of the 98 patients had obstetric histories. Six polymyositis and 9 dermatomyositis patients became pregnant after disease onset. The pregnancy outcomesin these cases were good, except in the following cases: 1 disease reactivation, 1 intrauterine growth retardation, 1 diabetes mellitus, 1 hypertension, 1 hypothyroidism, and 2 fetal losses (same patient). Moreover, 2 patients developed dermatomyositis during pregnancy and 4 (2 polymyositis and 2 dermatomyositis) during the postpartum period with good control after glucocorticoid and immunosuppressant therapy. Conclusions: The adverse obstetric events were related to clinical intercurrences and thepregnancy does not seem to carry a worse prognosis specifically in disease (for example:disease relapsing). Moreover, dermatomyositis or polymyositis onset during pregnancy orthe postpartum period had good outcome after drug therapy. .

Nefropatia por IgA e polimiosite: uma rara associação / IgA nephropathy and polymyositis: a rare association

A polimiosite é uma miopatia inflamatória idiopática sistêmica que, além da manifestação muscular, pode eventualmente cursar com acometimento respiratório, do trato gastrintestinal e, raramente, renal. Neste último caso, há descrição de apenas dois casos de nefropatia por IgA em pacientes com miopatia, ambos em dermatomiosite. Em contrapartida, relatamos pela primeira vez esta rara associação em polimiosite.

Polymyositis is a systemic and idiopathic inflammatory myopathy that, besides muscle manifestation, may occur with respiratory involvement, gastrointestinal tract and rarely renal involvement. In this latter, there are only two cases of IgA nephropathy, but both in dermatomyositis. On the other hand, we reported, for the first time, a case of IgA nephropathy in polymyositis.

Complex repetitive discharge on electromyography as a risk factor for malignancy in idiopathic inflammatory myopathy

BACKGROUND/AIMS: We investigated the electromyography (EMG) findings and demographic, clinical, and laboratory features that may predict the development of malignancy in patients with idiopathic inflammatory myopathy (IIM). METHODS: In total, 61 patients, 36 with dermatomyositis and 25 with polymyositis, were included. Patients were divided into those with and without malignancies, and comparisons were made between the groups in terms of their demographic, clinical, laboratory, and EMG findings. RESULTS: The frequencies of malignancies associated with dermatomyositis and polymyositis were 22% and 8%, respectively. Patients with malignancies showed a significantly higher incidence of dysphagia (odds ratio [OR], 21.50; 95% confidence interval [CI], 3.84 to 120.49), absence of interstitial lung disease (ILD; OR, 0.12; 95% CI, 0.01 to 0.98), and complex repetitive discharge (CRD) on the EMG (OR, 26.25; 95% CI, 2.67 to 258.52), versus those without. After adjustment for age, dysphagia and CRD remained significant, while ILD showed a trend for a difference but was not statistically significant. Multivariate analysis revealed that the CRD conferred an OR of 25.99 (95% CI, 1.27 to 531.86) for malignancy. When the frequency of malignancy was analyzed according to the number of risk factors, patients with three risk factors showed a significantly higher incidence of malignancy, versus those with fewer than two (p = 0.014). CONCLUSIONS: We demonstrated for the first time that CRD on the EMG was an additional independent risk factor for malignancy in IIM. Further studies on a larger scale are needed to confirm the importance of CRD as a risk factor for malignancy in IIM.

Camptocormia secundária à polimiosite / Camptocormia secondary to polymyositis

A camptocormia é uma doença postural caracterizada por flexão anormal da coluna toracolombar que surge na posição ereta, aumenta durante a caminhada e desaparece na posição supina. Na literatura, há descrição de apenas cinco casos de camptocormia secundária a miopatias inflamatórias idiopáticas. No presente relato de caso, descrevemos um paciente do sexo masculino, de 67 anos, com polimiosite há 18 anos, cursando com quadro compatível com camptocormia (estável e sem progressão do quadro clínico). A polimiosite é uma miopatia inflamatória idiopática caracterizada clinicamente por fraqueza muscular simétrica predominantemente proximal dos membros. Entretanto, sendo uma doença autoimune sistêmica, é plausível que ocorra acometimento de musculatura esquelética de forma difusa, incluindo a paravertebral, podendo manifestar-se com camptocormia.

Camptocormia is a postural affliction characterised by abnormal flexion of the thoracolumbar spine, which appears upon standing, increases with walking, and disappears in the supine position. Only five cases of camptocormia secondary to idiopathic infl ammatory myopathies have been described in the literature. In this case report, we describe the case of a male patient 67 years of age who suffered from polymyositis for 18 years, which was associated with manifestations compatible with camptocormia. The clinical manifestations were stable and did not progress. Polymyositis is an idiopathic inflammatory myopathy clinically characterised by symmetric weakness that predominantly affects the proximal muscles. Nevertheless, polymyositis is a systemic autoimmune disease; therefore, the skeletal muscles may be diffusely affected, including the paravertebral muscles, which may manifest as camptocormia.

Síndrome antifosfolípide e dermatomiosite/polimiosite: uma rara associação / Antiphospholipid syndrome and dermatomyositis/polymyositis: a rare association

A associação entre a síndrome antifosfolípide e as miopatias inflamatórias idiopáticas tem sido raramente descrita na literatura. No presente trabalho relatamos dois pacientes com síndrome antifosfolípide diagnosticados com dermatomiosite ou polimiosite. Realizamos também uma revisão da literatura acerca dessa sobreposição de duas entidades autoimunes sistêmicas.

The association between antiphospholipid syndrome and idiopathic inflammatory myopathies has been rarely reported in the literature. In this paper we report two patients with antiphospholipid syndrome diagnosed with concomitant dermatomyositis or polymyositis. We also reviewed the literature on this overlapping of two systemic autoimmune entities.

Prevalência de manifestações clínico-laboratoriais e comorbidades na polimiosite segundo o gênero / Prevalence of clinical and laboratory manifestations and comorbidities in polymyositis according to gender

OBJETIVO: Analisar a distribuição e a influência do gênero na polimiosite (PM), quanto às manifestações clínico-laboratoriais, evolução e comorbidades. MÉTODOS: Estudo de coorte retrospectivo, unicêntrico, em que foram avaliados 75 pacientes consecutivos com PM (Bohan e Peter, 1975) entre 1990 e 2010. Os exames complementares referem-se ao início do diagnóstico da PM. RESULTADOS: Este estudo avaliou 52 mulheres e 23 homens (razão 2,3:1), a maioria de cor branca (84,0 por cento), com média de idade de 42,7 ± 13,7 anos (16 a 67 anos), e duração média de doença de 6,9 ± 5,5 anos (0 a 20 anos). Aproximadamente 50 por cento apresentaram recidiva da doença durante o acompanhamento, com 4,0 por cento de óbitos. Apesar disso, dois terços encontravam-se em remissão no desfecho do estudo. Não houve diferença entre os gêneros quanto à distribuição das características demográficas, clínico-laboratoriais, evolução clínica e terapia medicamentosa instituída. Com relação às comorbidades, houve alta prevalência de hipertensão arterial sistêmica (38,7 por cento) e diabetes mellitus (17,3 por cento), igualmente distribuídas entre os gêneros. Verificou-se alta prevalência de depressão e fibromialgia, porém apenas no gênero feminino. CONCLUSÕES: A prevalência de PM entre mulheres foi maior (razão 2,3:1). A prevalência de comorbidades foi alta na casuística estudada, cabendo-nos priorizar seus controles e, assim, oferecer melhor qualidade de vida aos pacientes.

OBJECTIVE: To assess gender distribution in polymyositis (PM) and its influence on disease, regarding clinical and laboratory manifestations, outcome and comorbidities. METHODS: Retrospective single-center cohort study assessing 75 consecutive patients with PM (Bohan and Peter, 1975) from 1990 to 2010. Complementary tests were related to early diagnosis of PM. RESULTS: The study assessed 52 women and 23 men (ratio 2.3:1), most of whom white (84.0 percent), with a mean age of 42.7 ± 13.7 years (16 to 67 years), and mean disease duration of 6.9 ± 5.5 years (0 to 20 years). Approximately 50 percent experienced disease relapse during follow-up. Nevertheless, two thirds were in remission at the end of this study, with 4.0 percent of deaths. There was no difference between genders regarding demographic, clinical and laboratory characteristics, clinical outcome and the drug therapy instituted. Regarding comorbidities, there was a high prevalence of hypertension (38.7 percent) and diabetes mellitus (17.3 percent), equally distributed between genders. There was also a high prevalence of depression and fibromyalgia, which were only observed among females. CONCLUSIONS: The prevalence of PM was higher among women than among men (2.3:1). Because the prevalence of comorbidities was high in the case series studied, it is worth emphasizing the need for their control to provide better quality of life for patients with PM.

Polymyositis presenting with respiratory failure.

Polymyositis is a systemic autoimmune disorder characterised by inflammatory myopathy of the skeletal muscles predominantly affecting the proximal muscles and associated with extra-muscular manifestations like dysphagia and skin involvement. In this case report, we describe the occurrence of diaphragmatic weakness and respiratory failure due to polymyositis with relatively well preserved power in limb muscles.

A Case of Pneumatosis Cystoids Intestinalis with Polymyositis / 대한소화기학회지

Pneumatosis cystoides intestinalis (PCI), characterized by presence of intramural gas cyst in the intestinal wall is associated with various medical condition. Polymyosistis, however, is rarely associated with PCI. Few cases are reported in the world, and none has not been reported previously in Korea. A 67-year-old woman with polymyositis developed mild abdominal pain and abdominal distension during treatment with steroid and azathioprine. Radiographic findings including CT scan showed intraperitoneal free gas and intramural air, compatible with PCI. The patient's symptom and clinical findings improved after the treatment with antibiotics and high-dose oxygen therapy.

Malignancies in Korean Patients with Inflammatory Myopathy

The aim of this study was to assess the prevalence and the common type of malignancies in Korean patients with polymyositis (PM) and dermatomyositis (DM) and to evaluate the differences of clinical and laboratory findings between patients with malignancy and those without malignancy. Forty-one Korean patients, who were diagnosed as PM or DM, were enrolled in this study. They fulfilled the Bohan and Peter's criteria for a definite diagnosis of PM and DM. Patients with PM were 25 and those with DM were 16. Eleven out of 41 patients (26.8%) had malignancies. The malignancy was diagnosed simultaneously or later in 81.8% of patients with inflammatory myopathy (IM). The breast cancer was the most common malignancy. In this study, forty three years old as a screening age for malignancy had 88.9% sensitivity and 50.2% specificity. The serum levels of creatine kinase (CK) were significantly lower in patients with malignancy than those without malignancy.

Bucillamine-Induced Pemphigus Vulgaris in a Patient with Rheumatoid Arthritis and Polymyositis Overlap Syndrome

Bucillamine is a disease modifying anti-rheumatic drug, structurally similar to D-penicillamine. Although D-penicillamine-induced pemphigus has been not infrequently demonstrated, pemphigus associated with bucillamine was rarely reported. We describe a patient complicating pemphigus vulgaris after bucillamine treatment in rheumatoid arthritis (RA) and polymyositis (PM) overlap syndrome. PM and RA overlap syndrome was diagnosed three years ago and bucillamine was administrated for 20 months. Skin lesions including erythematous flaccid blisters on her chest, axillae, and back were occurred and were compatible with pemphigus vulgaris by typical pathology. Withdrawal from bucillamine and prednisolone treatment made rapid improvement of pemphigus lesions.

Hepatocellular Carcinoma, Polymyositis, Rhabdomyolysis, and Acute Renal Failure

A 55 yr-old man presented with progressive muscle weakness and oliguria for 5days. Laboratory findings suggested rhabdomyolysis complicated with acute renal failure. A diagnosis of polymyositis was based upon the proximal muscle weakness on both upper and lower limbs, elevated muscle enzyme levels, muscle biopsy findings and the needle electromyography findings. The muscle biopsy showed extensive muscle necrosis and calcification. Investigations for underlying malignancy demonstrated hepatocellular carcinoma. The patient was managed with hemodialysis and high dose prednisolone. His renal function was fully recovered and his muscle power did improve slightly, but he died of a rupture of the hepatic tumor. In our view, this is an interesting case in that the hepatocellular carcinoma was associated with polymyositis and fulminant rhabdomyolysis-induced acute renal failure requiring hemodialysis.

Tuberculous pyomyositis.

Tuberculosis, caused by Mycobacterium tuberculosis is a common infection both in immunocompromised and normal hosts. Its clinical manifestation can by divided as pulmonary and extrapulmonary form. Pyomyositis caused by M. tuberculosis is extremely rare. The authors report 2 patients, one with underlying dermatomyositis, and the other with polymyositis. The diagnosis was delayed according to nonspecific symptoms and masking effect of steroid therapy, which led to complications. Microscopy and culture of the pus confirmed the diagnosis. Surgical drainage was done and antituberculous therapy was given. The patient with dermatomyositis was complicated by drug induced hepatitis and died but the other was cured. Tuberculous pyomyositis should be considered in patients who are immunocompromised hosts.

Diagnosis of dermatomyositis and polymyositis: a study of 102 cases

Patients with dermatomyositis (DM) or polymyositis (PM) were studied retrospectively. The patients were divided into four groups: definite PM 24, probable PM 19, definite DM 34 and mild-early DM 25 cases. PM patients complained more often proximal muscle weakness [p <0.01]. DM patients complained more arthralgia [p <0.05], dysphagia [p <0.03] and weight loss [p <0.04]. Five patients had a malignant neoplasm and 9 had other connective-tissue disease. DM presented higher ESR than PM [p <0.002]. PM presented more significant increase in creatine kinase (CK) [p <0.02] and in alanine aminotransferase (ALT) [p <0.001] levels. Electromyography showed myopathic pattern in 76 percent. Muscle biopsy was the definitive test. Perifascicular atrophy was more frequent in definite DM than in mild-early DM group [p <0.03]. CONCLUSION: A small association with connective-tissue diseases and neoplasms was found. DM and PM are clinically different. DM presents systemic involvement affecting the skin, developing more severe arthralgia, dysphagia and weight loss and presenting higher values of ESR. PM presents a restricted and more significant involvement of muscles generating more weakness complaints and higher levels of serum muscle enzymes

Toxoplasmosis-dermatomiositis: una asociación fortuita? / Toxoplasmosis-polymiositis-dermatomyositis: a fortuitous association?

Se describe el caso de una paciente de veinte años de edad con dermatopolimiositis (DM/PM) y toxoplasmosis (Tx). El tratamiento para Tx instituido precozmente mejoró la respuesta de la enferma. Los pacientes con DM/PM deberían ser estudiados para Tx a través de la detección de IgG, IgM y también IgA específica
