El péptido Pro-BNP como predictor de daño cardíaco en pacientes con esclerosis sistémica / Pro-BNP Peptide as a Predictor of Cardiac Damage in Systemic Sclerosis Patients

Introducción: La esclerosis sistémica es una enfermedad crónica del tejido conectivo de carácter autoinmune, de causa desconocida, que produce exceso de colágeno provocando fibrosis en la piel, con afectación de órganos internos. Los anticuerpos frecuentes son: antitopoisomerasa 1 y anticentrómero. Las formas clínicas son la cutánea difusa y cutánea limitada. La prevalencia de la afectación cardíaca varía entre un 8-28 por ciento y en fases tardías la presencia de signos y síntomas cardiovasculares es de mal pronóstico y una de las principales causas de mortalidad. Objetivo: Determinar la asociación entre afectación cardíaca y las formas clínicas, el pro-péptido natriurético cerebral N-terminal (NT-proBNP) y los autoanticuerpos en la esclerosis sistémica. Métodos: Se realizó un estudio descriptivo transversal de un universo de 140 pacientes, la muestra fue de 54 pacientes. Se le realizó ecocardiograma, niveles de NT-proBNP, anti-scl 70, anticentrómero y determinación de formas clínicas a todos los pacientes que cumplieron criterios de inclusión y que fueron atendidos en el Hospital: Hermanos Ameijeiras Habana-Cuba, entre julio de 2016 a diciembre de 2017. Resultados: La edad media fue 51,76 ± 12,82. Sexo femenino en un 96,3 por ciento. El 72,2 por ciento era piel blanca. La afectación cardíaca de la EScd fue de 77,5 por ciento, hormona NT-proBNP tuvo niveles elevados en un 55,0 por ciento. Los anti-scl-70 estuvieron negativos en el 70 por ciento (n = 28) de los pacientes con afectación cardíaca. El anti-centrómero estuvo negativo en el 95,0 por ciento (n = 38). Conclusiones: Se determinó que la afectación cardíaca en pacientes con esclerosis sistémica, es independiente de las formas clínicas y de la presencia de autoanticuerpos. Los pacientes que tuvieron los niveles séricos de NT-proBNP elevados presentaron afectación cardíaca(AU)

Introduction: Systemic sclerosis is a chronic autoimmune connective tissue disease of unknown cause, which produces excess collagen causing fibrosis in the skin, affecting internal organs. Common antibodies are antitopoisomerase 1 and anticentromere. The clinical forms are diffuse cutaneous and limited cutaneous. The prevalence of cardiac involvement varies between 8-28percent and in late stages the presence of cardiovascular signs and symptoms have poor prognosis and one of the main causes of mortality. Objective: To determine the association between cardiac involvement and clinical forms, N-terminal pro-brain natriuretic peptide (NT-proBNP) and autoantibodies in SSc. Methods: A cross-sectional descriptive study of a universe of 140 patients was carried out. Fifty four patients made up the sample. An echocardiogram, NT-proBNP, Anti-scl 70, anticentromere levels and determination of clinical forms were performed on all patients who met the inclusion criteria and who were treated at Hermanos Ameijeiras hospital in Havana, Cuba, from July 2016 to December 2017. Results: The mean age was 51.76 ± 12.82. Female sex accounted 96.3percent. 72.2percent were white skinned. Cardiac involvement of EScd was 77.5percent, NT-proBNP hormone had high levels in 55.0percent. Anti-scl-70 were negative in 70percent (n=28) of patients with cardiac involvement. Anti-centromere (ACT) was negative in 95.0percent (n=38). Conclusions: Cardiac involvement in patients with SS is independent of the clinical forms and the presence of autoantibodies. Patients with elevated NT-proBNP serum levels had cardiac involvement(AU)

Incidence and prevalence of systemic sclerosis in Campo Grande, State of Mato Grosso do Sul, Brazil / Incidência e prevalência de esclerose sistêmica em Campo Grande, Estado de Mato Grosso do Sul, Brasil

Abstract Introduction: Systemic sclerosis is an autoimmune disease which shows extreme heterogeneity in its clinical presentation and that follows a variable and unpredictable course. Although some discrepancies in the incidence and prevalence rates between geographical regions may reflect methodological differences in the definition and verification of cases, they may also reflect true local differences. Objectives: To determine the prevalence and incidence of systemic sclerosis in the city of Campo Grande, state capital of Mato Grosso do Sul (MS), Brazil, during the period from January to December 2014. Methods: All health care services of the city of Campo Grande – MS with attending in the specialty of Rheumatology were invited to participate in the study through a standardized form of clinical and socio-demographic assessment. Physicians of any specialty could report a suspected case of systemic sclerosis, but necessarily the definitive diagnosis should be established by a rheumatologist, in order to warrant the standardization of diagnostic criteria and exclusion of other diseases resembling systemic sclerosis. At the end of the study, 15 rheumatologists reported that they attended patients with systemic sclerosis and sent the completed forms containing epidemiological data of patients. Results: The incidence rate of systemic sclerosis in Campo Grande for the year 2014 was 11.9 per million inhabitants and the prevalence rate was 105.6 per million inhabitants. Systemic sclerosis patients were mostly women, white, with a mean age of 50.58 years, showing the limited form of the disease with a mean duration of the disease of 8.19 years. Regarding laboratory tests, 94.4% were positive for antinuclear antibody, 41.6% for anti-centromere antibody and 19.1% for anti-Scl70; anti-RNA Polymerase III was performed in 37 patients, with 16.2% positive. Conclusions: The city of Campo Grande, the state capital of MS, presented a lower incidence/prevalence of systemic sclerosis in comparison with those numbers found in US studies and close to European studies’ data.

Resumo Introdução: A esclerose sistêmica (ES) é uma enfermidade autoimune, extremamente heterogênea na sua apresentação clínica e segue um curso variável e imprevisível. Embora algumas discrepâncias nas taxas de incidência e prevalência entre regiões possam refletir as diferenças metodológicas na definição e verificação dos casos, elas também podem refletir as verdadeiras diferenças locais. Objetivos: Conhecer a prevalência e incidência da ES na cidade de Campo Grande, capital do Estado de Mato Grosso do Sul (MS), Brasil, de janeiro a dezembro de 2014. Métodos: Todos os serviços de saúde de Campo Grande (MS) que tinham atendimentos na especialidade de reumatologia foram convidados a participar do estudo por meio de ficha padronizada de avaliação clínica e sociodemográfica. Médicos de qualquer especialidade poderiam reportar um caso suspeito de ES, mas obrigatoriamente o diagnóstico definitivo deveria ser feito por um reumatologista, para garantir a padronização dos critérios diagnósticos e excluir outras doenças que se assemelham à ES. No fim do estudo 15 reumatologistas relataram ter atendido pacientes com diagnóstico de ES e enviaram os formulários preenchidos com os dados epidemiológicos dos pacientes. Resultados: A taxa de incidência de ES em Campo Grande em 2014 foi de 11,9 por milhão/habitantes e a de prevalência foi de 105,6 por milhão/habitantes. Os pacientes com ES eram principalmente mulheres, da cor branca, média de 50,58 anos, forma limitada da doença e tempo de evolução médio da doença de 8,19 anos. Em relação aos exames laboratoriais, observou-se a positividade de 94,4% para o ANA, 41,6% para ACA e 19,1% para anti-Scl70, o anticorpo anti-POL3 foi feito em apenas 37 pacientes, com positividade de 16,2%. Conclusões: A capital do Estado de Mato Grosso do Sul, Campo Grande, apresentou dados de incidência e prevalência de ES inferiores aos encontrados em estudos americanos e próximos aos dados observados em estudos europeus.

Familial autoimmunity and polyautoimmunity in 60 Brazilian Midwest patients with systemic sclerosis / Autoimunidade familial e poliautoimunidade em 60 pacientes portadores de esclerose sistêmica da região Centro-Oeste do Brasil

ABSTRACT Introduction: Systemic sclerosis (SSc) is a connective tissue disease of unknown etiology, characterized by a triad of vascular injury, autoimmunity and tissue fibrosis. It is known that a positive family history is the greatest risk factor already identified for the development of SSc in a given individual. Preliminary observation of a high prevalence of polyautoimmunity and of familial autoimmunity in SSc patients support the idea that different autoimmune phenotypes may share common susceptibility variants. Objectives: To describe the frequency of familial autoimmunity and polyautoimmunity in 60 SSc patients in the Midwest region of Brazil, as well as to report the main autoimmune diseases observed in this association of comorbidities. Methods: A cross-sectional study with recruitment of 60 consecutive patients selected at the Rheumatology Department, University Hospital, Medicine School, Federal University of Mato Grosso do Sul (FMUFMS), as well as interviews of their relatives during the period from February 2013 to March 2014. Results: A frequency of 43.3% of polyautoimmunity and of 51.7% of familial autoimmunity in SSc patients was found. Patients with the presence of polyautoimmunity and familial autoimmunity presented primarily the diffuse form of SSc, but this indicator did not reach statistical significance. The autoimmune diseases most frequently observed in polyautoimmunity patients were: Hashimoto's thyroiditis (53.8%), Sjögren's syndrome (38.5%), and inflammatory myopathy (11.5%). The main autoimmune diseases observed in SSc patients' relatives were: Hashimoto's thyroiditis (32.3%), rheumatoid arthritis (22.6%), and SLE (22.6%). The presence of more than one autoimmune disease in SSc patients did not correlate with disease severity or activity. Conclusions: From the high prevalence of coexisting autoimmune diseases found in SSc patients, we stress the importance of the concept of shared autoimmunity, in order to promote a continued vigilance and promptly diagnose other possible autoimmune disease in patients, or in their kin.

RESUMO Introdução: A esclerose sistêmica (ES) é uma enfermidade do tecido conjuntivo de etiologia desconhecida, caracterizada pela tríade de injúria vascular, autoimunidade e fibrose tecidual. Sabe-se que uma história familiar positiva representa o maior fator de risco já identificado para o desenvolvimento da ES em um determinado indivíduo. Observação prévia de alta prevalência de poliautoimunidade e de autoimunidade familiar em pacientes com ES reforça a ideia de que fenótipos autoimunes distintos podem dividir variantes comuns de susceptibilidade. Objetivos: Descrever a frequência de autoimunidade familiar e de poliautoimunidade em 60 pacientes com ES da região Centro-Oeste do Brasil, bem como relatar as principais doenças autoimunes observadas nessa associação de comorbidades. Métodos: Estudo transversal com recrutamento de 60 pacientes consecutivos, selecionados no Serviço de Reumatologia do Hospital Universitário da Faculdade de Medicina da Universidade Federal de Mato Grosso do Sul (FMUFMS), bem como entrevista de seus parentes, de fevereiro de 2013 a março de 2014. Resultados: Foi encontrada uma frequência de 43,3% de poliautoimunidade e de 51,7% de autoimunidade familiar nos pacientes com ES. Os pacientes com presença de poliautoimunidade e de autoimunidade familiar eram principalmente da forma difusa de ES, porém esse índice não atingiu significância estatística. As doenças autoimunes mais comumente observadas nos pacientes com poliautoimunidade foram: tireoidite de Hashimoto (53,8%), síndrome de Sjögren (38,5%) e miopatia inflamatória (11,5%). As principais doenças autoimunes observadas nos parentes dos pacientes com ES foram: tireoidite de Hashimoto (32,3%), artrite reumatoide (22,6%) e LES (22,6%). A presença de mais de uma enfermidade autoimune em pacientes com ES não se correlacionou com maior gravidade ou atividade da doença. Conclusões: A partir da alta prevalência encontrada de doenças autoimunes coexistentes em pacientes com ES, salientamos a importância do conceito de autoimunidade compartilhada, de forma a promover uma vigilância constante e diagnosticar prontamente uma possível outra doença autoimune nos pacientes ou em seus parentes.

A Study on Pulmonary Complications of Systemic Sclerosis in Eastern India.

Aim. This study was undertaken to find out the characteristics of clinical, radiological and functional changes affecting the respiratory system in patients with systemic sclerosis (SSc) from eastern India, and the association of these characteristics with pulmonary hypertension. Methods. This was a cross-sectional, observational study involving 46 patients. Other than the routine tests, anti-nuclear antibody (ANA), spirometry, diffusing capacity of lung for carbon monoxide (DLCO) measurement, chest radiograph, highresolution computed tomography (HRCT) of thorax, 6-minute walk test and echocardiography were done. Results. Out of a total of 46 patients, 27 patients had diffuse cutaneous SSc (dcSSc) and 19 had limited cuteaneous SSc (lcSSc). Eleven patients had pulmonary hypertension. The HRCT revealed diffuse parenchymal lung disease (DPLD) in 32 (65%) cases. The ANA was positive in 83% cases. Anti-Scl70 was found in 41% of patients with dcSSc and anti-centromere antibody was found in 47% of patients with lcSSc. Spirometry revealed restrictive pattern in 30 patients; 9 had obstruction; and the rest were normal. The DLCO was abnormal in 38 patients. A strong correlation was found between reduction in DLCO and pulmonary artery systolic pressure (PASP). Also, a strong association was observed between a drop of >4% in oxygen saturation on 6-minute walk test and presence of pulmonary arterial hypertension (PAH). Conclusions. Majority of the patients with SSc had restrictive lung disease with abnormal DLCO and features resembling non-specific interstitial pneumonia. Nucleolar ANA was predominantly found in patients having PAH. Presence of DPLD had a negative association with presence of anti-centromere antibody. Reduction in DLCO and a fall of >4% in oxygen saturation on 6-minute walk test may be used as predictors of PAH in asymptomatic individuals.

Autoanticorpos em esclerodermia e sua associação ao perfil clínico da doença: estudo em 66 pacientes do sul do Brasil / Autoantibodies in scleroderma and their association with the clinical profile of the disease: a study of 66 patients from southern Brazil

FUNDAMENTOS: A esclerodermia é uma colagenose relativamente rara, cujo perfil de autoanticorpos está associado a diferentes manifestações clínicas. A prevalência de autoanticorpos na esclerodermia sofre influência racial e genética. OBJETIVO: Estudar a prevalência dos anticorpos anti-Scl-70, anticentrômero e anti-U1-RNP em pacientes com esclerodermia do sul do Brasil e verificar suas associações às manifestações clínicas. MÉTODOS: Estudo retrospectivo de análise de 66 pacientes com esclerodermia para presença de anti-Scl-70, anticentrômero (ACA) e anti-U1-RNP e de manifestações clínicas como: Raynaud, cicatrizes estelares, necrose digital, telangiectasias, calcinose, fibrose pulmonar, pleurites, pericardites, miocardiopatias, artralgias e artrites, grau de esclerose da pele, contraturas articulares e atritos de tendão, hipertensão pulmonar, manifestações esofágicas e crise renal. RESULTADOS: A prevalência do anti-Scl-70 foi de 17,8 por cento, a do ACA, de 33,3 por cento, e a do U1 RNP foi de 11,8 por cento. O anti-Scl-70 estava associado à forma difusa da doença (p=0,015), presença de miocardiopatias (p=0,016) e de cicatrizes estelares (p=0,05); o anticentrômero foi mais comum na forma limitada, embora sem significância estatística e mostrou-se protetor para as miocardiopatias (p=0,005). O anti-U1-RNP foi mais comum nas formas de superposição (p=0,0004). CONCLUSÃO: A prevalência e o perfil de associações clínicas dos autoanticorpos em esclerodermia de pacientes brasileiros assemelham-se aos da literatura mundial.

BACKGROUND: Scleroderma is a fairly rare connective tissue disease whose autoantibody profile is associated with different clinical manifestations. The prevalence of autoantibodies in scleroderma is influenced by race and genetics. OBJECTIVE: To study the prevalence of anti-Scl-70, anti-centromere (ACA) and anti-U1-RNP antibodies in patients with scleroderma in southern Brazil and verify their association with clinical manifestations of the disease. METHODS: A retrospective study involving 66 patients with scleroderma for the presence of anti-Scl-70, anti-centromere and anti-U1-RNP and of clinical manifestations such as Raynaud's phenomenon, digital micro scars, digital necrosis, telangiectasias, calcinosis, pulmonary fibrosis, pleuritis, pericarditis, cardiomyopathy, arthralgia and arthritis, skin sclerosis, joint contractures, tendon friction rubs, pulmonary hypertension, esophageal disorders and renal crisis. RESULTS: The prevalence of anti-Scl-70 was 17.8 percent , that of ACA was 33.3 percent and the prevalence of U1 RNP was 11.8 percent. Anti-Scl-70 was associated with the diffuse form of the disease (p = 0.015), presence of cardiomyopathies (p = 0.016) and digital micro scars (p = 0.05). Anti-centromere was more common in the limited form, although it was not statistically significant, and had a protective role associated with cardiomyopathies (p = 0.005). Anti-U1-RNP was more common in the overlap forms (p = 0.0004). CONCLUSION: The prevalence and profile of clinical associations of autoantibodies in Brazilian patients with scleroderma are similar to those found in the literature.
