Fecal calprotectin levels in acute anterior uveitis in patients with spondyloarthritis / Níveis de calprotectina fecal na uveite anterior aguda em pacientes com espondiloartrites

ABSTRACT Purpose: This study measured fecal calprotectin levels in a series of patients with anterior uveitis in order to determine whether anterior uveitis patients with associated spondyloarthritis have higher levels of fecal calprotectin than patients with anterior uveitis of other etiologies. A third group of patients with spondyloarthritis without uveitis was also evaluated to understand the role of acute anterior uveitis in increasing fecal calprotectin. Methods: In this cross-sectional study, 28 patients were divided into three groups: (a) Group 1, spondyloarthritis and uveitis (n=9); (b) Group 2, spondyloarthritis without uveitis (n=10); and (c) Group 3, uveitis without spondyloarthritis (n=9). The levels of fecal calprotectin were determined. Results: Groups 1 and 2 showed higher median fecal calprotectin levels (101.0 and 93.0 µg/g, respectively) compared with Group 3 (9.0 µg/g) (p=0.02). However, no relationship between fecal calprotectin levels and the presence of uveitis with spondyloarthritis could be demonstrated. Conclusion: Patients with spondyloarthritis with or without acute anterior uveitis have significantly elevated levels of fecal calprotectin. This test may be useful for differentiating spondyloarthrit-associated uveitis from uveitis of other etiologies.

RESUMO Objetivo: Este estudo avaliou os níveis de calprotectina fecal em uma série de pacientes com uveíte anterior na tentativa de determinar se pacientes com uveíte associada com espondiloartrites apresentam níveis mais elevados desta proteína do que pacientes com uveíte anterior de outras etiologias. Um terceiro grupo com espondiloartrites sem uveíte também foi incluído na avaliação para entendimento do papel da uveíte anterior no aumento da calprotectina fecal. Métodos: Estudo transversal de 28 pacientes divididos em três grupos: (a) com espondiloartrites e uveíte (n=9); (b) com espondiloartrites sem uveíte (n=10) e (c) com uveíte sem espondiloartrites (n=9). A dosagem de calprotectina fecal foi avaliada. Resultados: Pacientes com uveíte anterior associada a espondiloartrites apresentaram valores medianos maiores de calprotectina fecal (101 µg/g) que os valores dos pacientes com uveíte sem espondiloartrites (9 µg/g), pacientes com espondiloartrites sem uveíte que também demonstraram valores maiores (93.0 µg/g) que os dos pacientes com uveíte sem espondiloartrites (p=0,02). Conclusão: Pacientes com espondiloartrites com e sem uveíte anterior aguda demonstraram níveis significativamente elevados de calprotectina fecal. Este teste pode ser útil na diferenciação entre uveítes associadas com espondiloartrites de uveítes de outras etiologias. Entretanto, não foi possível demonstrar associação entre o aumento dos níveis de calprotectina fecal e a presença da uveíte em espondiloartrites.

Ranking the importance of their own diseases: A positioning analysis in rheumatic patients and their proxies.

INTRODUCTION/OBJECTIVE: To assess the positioning that patients with systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), ankylosing spondylitis (AS) and their proxies give to their diseases. METHODS: Subjects completed a self-administered questionnaire to rank 11 diseases from "worst" to "least bad". Then they defined the "worst" disease and ranked 10 diseases from highest to lowest importance from a list including "my rheumatic disease/my relative's disease". The lists of the included diseases represented the mindshare from a sample of healthy adults. RESULTS: There were 570 respondents (104 SLE, 99 RA, 82 AS, and 285 proxies). Rheumatoid arthritis was considered the third-worst disease (recoded ranking first by 41% of patients and 43% proxies, second by 49% and 44%, and third by 10% and 13%). A disease that kills was the preferred definition for the worst disease. "My disease/my relative's disease" was ranked fourth in importance (first by 41% of patients, second by 38%, and third by 21%). Rankings were not associated with age, schooling, disease duration, or setting. DISCUSSION AND CONCLUSIONS: Most respondents ranked their own disease considerably lower than other non-rheumatic conditions.

Comparison between STIR and T2-weighted SPAIR sequences in the evaluation of inflammatory sacroiliitis: diagnostic performance and signal-to-noise ratio / Comparação do desempenho diagnóstico e da relação sinal-ruído das sequências SPAIR T2 e STIR na avaliação de sacroiliite inflamatória

Abstract Objective: To compare two different fat-saturated magnetic resonance imaging (MRI) techniques-STIR and T2 SPAIR-in terms of image quality, as well as in terms of their diagnostic performance in detecting sacroiliac joints (SIJ) active inflammation. Materials and Methods: We included 69 consecutive patients with suspected spondyloarthritis undergoing MRI between 2012 and 2014. The signal-to-noise ratio (SNR) was calculated with the method recommended by the American College of Radiology. Two readers evaluated SIJ MRI following ASAS criteria to assess diagnostic performance regarding the detection of active SIJ inflammation. T1 SPIR Gd+ sequence was used as the reference standard. Results: The mean SNR was 72.8 for the T1 SPIR Gd+ sequence, compared with 14.1 and 37.6 for the STIR and T2 SPAIR sequences, respectively. The sensitivity and specificity of STIR and SPAIR T2 sequences did not show any statistically significant differences, for the diagnosis of sacroiliitis with active inflammation. Conclusion: Our results corroborate those in the recent literature suggesting that STIR sequences are not superior to T2 SPAIR sequences for SIJ evaluation in patients with suspected spondyloarthritis. On 1.5-T MRI, T2-weighted SPAIR sequences provide better SNRs than do STIR sequences, which reinforces that T2 SPAIR sequences may be an advantageous option for the evaluation of sacroiliitis.

Resumo Objetivo: O objetivo deste estudo foi comparar a qualidade da imagem das técnicas de saturação de gordura T2 SPAIR e STIR e, adicionalmente, comparar o desempenho diagnóstico das duas sequências para detecção de inflamação ativa nas imagens de ressonância magnética (RM) das sacroilíacas. Materiais e Métodos: Foram incluídos 69 pacientes consecutivos que realizaram RM das articulações sacroilíacas no período de 2012 a 2014. O cálculo da relação sinal/ruído (RSR) foi realizado pelo método do Colégio Americano de Radiologia. O desempenho diagnóstico foi realizado utilizando os resultados da leitura das imagens da sequência T1 SPIR Gd+ como referência. Resultados: A avaliação da RSR mostrou média de 72,8 para a sequência T1 SPIR Gd+. A sensibilidade e a especificidade das sequências STIR e SPAIR 2 para o diagnóstico de sacroiliite com inflamação ativa não apresentaram diferenças estatisticamente significantes. Conclusão: Nossos resultados reforçam a literatura recente sugerindo que não há superioridade da sequência STIR em relação à sequência SPAIR T2 para a avaliação das sacroilíacas em pacientes com espondiloartrite. A sequência SPAIR T2 apresenta melhor RSR em relação à sequência STIR em imagens de RM de 1,5 T, o que reforça que a sequência SPAIR T2 possa ser utilizada como opção vantajosa na avaliação da sacroiliite inflamatória.

Homologies and heterogeneity between Rheumatology Congresses: Mexican, American College of Rheumatology and European League Against Rheumatism. / Análisis de homologías y heterogeneidad entre congresos de Reumatología: mexicanos, ACR y EULAR.

BACKGROUND: Medical meetings are a tool to help physicians advance and update their medical knowledge. Their quality is the responsibility of colleges and institutions. OBJECTIVE: To assess and compare the academic level of four different annual rheumatology meetings. MATERIAL AND METHODS: As a source of information, we used the abstracts published in the supplements of the journal Reumatología Clínica, SE1 Vol. 12, issued in February 2016, SE 1 Vol. 13 issued in February 2017, the electronic application of the 2016 ACR/ARHP of the 2016 American Congress of Rheumatology, devoted to the works presented at the 44th Mexican Congress of Rheumatology (CMR 44), the 45th Mexican Congress of Rheumatology (CMR 45), and the 2016 ACR/ARHP Annual Meeting (ACR 2016), as well as the Web page on the files and abstracts of EULAR 2017, respectively; from each work we compiled information on the major disease being referred to, the type of information provided and the type of report. We should point out that some were combined conditions or designs, from which we selected that which we considered to be the most important. RESULTS: In all, 275, 340, 3275 and 4129 studies were submitted to the XLIV Mexican Congress of Rheumatology, XLV Mexican Congress of Rheumatology, the 2016 ACR/ARHP Annual Meeting and EULAR 2017, respectively. Rheumatoid arthritis was the most common disorder, dealt with in 23%, 26%, 21% and 27% in CMR 44, CMR 45, 2016 ACR and EULAR 2017, respectively, followed by systemic lupus erythematosus; in third place, Mexican congresses reported trials related to systemic vasculitis, whereas spondylitis was the main subject of international congresses. In the case of rheumatoid arthritis, clinical topics accounted for 30% in the Mexican congresses and ACR, and nearly 20% in EULAR. Observational studies accounted for 40% in the Mexican congresses vs. 33% in 2016 ACR and 55% in EULAR 2017. Studies on basic science were minimal in the Mexican congress, whereas in 2016 ACR, they represented 21% and 12% in EULAR 2017. CONCLUSION: Rheumatology meetings constitute a tool to obtain adequate evidence-based medical knowledge in this important branch of medicine. For our Mexican Congress, we should encourage collaborative efforts between institutions, which will result in a greater number of controlled studies, clinical trials and basic studies that support the quality of the congress. We wish to emphasize that a greater diffusion of other musculoskeletal diseases is needed, not only autoimmune diseases, since the former represent an important percentage of the daily practice.

Necesidades de capacitación para el diagnóstico genético de espondiloartropatías en médicos del Hospital "Hermanos Ameijeiras" / Training needs for the genetic diagnosis of spondyloarthropathies in doctors of the "Hermanos Ameijeiras" Hospital

RESUMEN Fundamento: la exploración de necesidades de capacitación es esencial para el diseño de estrategias educacionales que eleven la formación cualitativa de los profesionales, la calidad de los servicios y la utilización racional de los recursos. Objetivo: identificar las necesidades de capacitación para el diagnóstico genético de espondiloartropatías y uveítis en médicos del Hospital Docente Clínico Quirúrgico "Hermanos Ameijeiras". Métodos: se realizó una investigación de tipo descriptiva cuanticualitativa, en la que se utilizaron métodos teóricos: análisis-síntesis, inducción-deducción e histórico-lógico; empíricos: revisión documental de indicaciones médicas y un cuestionario para clasificar las necesidades de capacitación en manifiestas y ocultas o encubiertas, y sentidas y no sentidas acerca de la correcta indicación del estudio genético para el diagnóstico de espondiloartropatías y uveítis; y matemático-estadísticos para el procesamiento de los datos. Resultados: la minoría de las indicaciones médicas mostró resultados positivos; es decir, los pacientes presentaron el alelo HLA B-27U. Las mayores insuficiencias de conocimientos sobre el tema las mostraron los residentes a diferencia de los especialistas que presentaron menos respuestas erróneas, aunque estos últimos manifestaron mayor percepción de necesidades de capacitación que los residentes, con lo que asumieron una actitud más abierta y flexible ante la superación. Conclusiones: se identificaron las necesidades de capacitación sobre el tema lo cual permite generar estrategias para lograr el uso racional de las herramientas moleculares en el diagnóstico genético de espondiloartropatías y uveítis en el personal médico.

ABSTRACT Background: the exploration of training needs is essential for the design of educational strategies that increase the qualitative training of professionals, the quality of services and the rational use of resources. Objective: to identify training needs for the genetic diagnosis of spondyloarthropathies and uveitis in physicians of the "Hermanos Ameijeiras" Clinical Surgical Teaching Hospital. Methods: a descriptive quantitative-qualitative research was carried out, in which theoretical methods were used: analysis-synthesis, induction-deduction and historical-logical; empirical ones: documentary review of medical indications and a questionnaire to classify the training needs in manifest and hidden or covert, and felt and not felt about the correct indication of the genetic study for the diagnosis of spondyloarthropathies and uveitis; and mathematical-statistics for data- processing. Results: the minority of the medical indications showed positive results; that is, the patients presented the HLA B-27U allele. The greatest knowledge shortcomings on the subject were shown by the residents, unlike the specialists who presented less wrong answers, although the latter expressed a greater perception of training needs than the residents, so they assumed a more open and flexible attitude towards overcoming. Conclusions: training needs on the subject were identified, which allows generating strategies to achieve the rational use of molecular tools in the genetic diagnosis of spondyloarthropathies and uveitis in medical personnel.

Comportamiento del síndrome poliglandular autoinmune tipo III en una cohorte de ocho casos / Behavior of autoimmune polyglandular syndrome type III in a cohort of eight cases

Introducción: el síndrome poliglandular autoinmune es una afección que se caracteriza por la presencia de varias afecciones entre las que destaca la presencia de diabetes insulinodependiente, enfermedad tiroidea y enfermedad autoinmune no tiroidea fundamentalmente. Pueden presentarse otras afecciones específicas como es el caso del vitiligo, la psoriasis, alopecia y anemia perniciosa entre otras. Objetivo: conocer el comportamiento clínico y epidemiológico del síndrome poliglandular autoinmune tipo III en pacientes con enfermedades reumáticas. Método: estudio de tipo descriptivo y retrospectivo, de una serie de 8 casos con presencia de enfermedades que permiten el diagnóstico de síndrome autoinmune tipo III. Se procedió a realizar una revisión exhaustiva de las historias clínicas que posibilitó la recogida de la información mediante un cuestionario creado específicamente para la investigación. La información recogida permitió describir las variables sociodemográficas, clínicas y de laboratorio planteadas para la investigación. Resultados: el promedio de edad fue de 47.34 ± 5 años. El 87.5 por ciento correspondió al sexo femenino y el 75 por ciento de los casos refirió algún hábito nocivo, de los cuales el de mayor representatividad (83,3 por ciento) fue el sedentarismo. El hipotiroidismo (87,5 por ciento) y el síndrome de Sjögren (37,5 por ciento) fueron las enfermedades que con mayor frecuencia se presentaron. Conclusiones: el síndrome poliglandular autoinmune es una afección múltiple que incluye diversas afecciones generando polifarmacia que pude incidir negativamente en la adherencia terapéutica de estos pacientes. La presencia de hábitos nocivos puede ser considerada como un posible agente desencadenante de muchas de las afecciones que componen el síndrome. Existe una tendencia a minimizar la importancia de las afecciones dermatológicas lo que genera un subregistro de las mismas(AU)

Introduction: autoimmune polyglandular syndrome is a condition that is characterized by the presence of several conditions among which the presence of insulin-dependent diabetes, thyroid disease and non-thyroid autoimmune disease is fundamental. There may be other specific conditions such as vitiligo, psoriasis, alopecia and pernicious anemia among others. Objective: to know the clinical and epidemiological behavior of type III autoimmune polyglandular syndrome in patients with rheumatic diseases. Methodo: estudio de tipo descriptivo y retrospectivo, de una serie de 8 casos con presencia de enfermedades que permiten el diagnóstico de síndrome autoinmune tipo III. Se procedió a realizar una revisión exhaustiva de las historias clínicas que posibilitó la recogida de la información mediante un cuestionario creado específicamente para la investigación. La información recogida permitió describir las variables sociodemográficas, clínicas y de laboratorio planteadas para la investigación. Results: the average age was 47.34 ± 5 years. 87.5 percent corresponded to the female sex and 75 percent of the cases reported some harmful habit, of which the one with the highest representation (83.3 percent) was a sedentary lifestyle. Hypothyroidism (87.5 percent) and Sjögren's syndrome (37.5 percent) were the diseases that most frequently occurred. Conclusions: autoimmune polyglandular syndrome is a multiple condition that includes various conditions generating polypharmacy that could negatively affect the therapeutic adherence of these patients. The presence of harmful habits can be considered as a possible triggering agent of many of the conditions that make up the syndrome. There is a tendency to minimize the importance of dermatological conditions, which causes underreporting(AU)

Electrocardiographic changes in spondyloarthritis and use of anti-TNF-α drugs: a retrospective study with 100 patients / Alterações eletrocardiográficas em espondiloartrites e uso de anti-TNF-α: estudo retrospectivo em 100 pacientes

ABSTRACT Objective To investigate the prevalence of electrocardiographic changes in patients with spondyloarthritis and to correlate these changes with use of anti-tumor necrosis factor-alpha (TNF-α) drugs and HLA-B27 positivity. Methods Retrospective study including 100 patients diagnosed with spondyloarthritis according to Assessment of SpondyloArthritis International Society (ASAS) criteria and 50 controls. Epidemiological and clinical features, results of inflammatory activity tests, HLA-B27 positivity, and medication use data were extracted from medical records. Disease activity was assessed using the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). All participants were submitted to electrocardiogram performed using a 12-lead device; rhythm, heart rate, conduction disorders and QT interval corrected using the Bazett formula were analyzed. Results Of 100 patients with spondyloarthritis, 51 were on anti-TNF-α drugs and 49 were not. HLA-B27 was detected in 53.1% of patients in the sample. Patients with spondyloarthritis had lower heart rate (p=0.06), longer QT interval (p<0.0001) and higher prevalence of right bundle branch block (p=0.014) compared to controls. Duration of disease was weakly correlated with heart rate (Rho=0.26; 95%CI: 0.06-0.44; p=0.008). The prevalence of right bundle branch block was positively correlated with HLA-B27 positivity. Use of Anti-TNF-α drugs did not interfere with electrocardiographic parameters. Conclusion Patients with spondyloarthritis had lower heart rate, longer QT interval and a higher prevalence of right bundle branch block compared to controls. HLA-B27 positivity was associated with the prevalence of right bundle branch block. Anti-TNF-α drugs had no impact on electrocardiographic findings.

RESUMO Objetivo Avaliar a prevalência de alterações eletrocardiográficas em pacientes com espondiloartrites, correlacionando-as com o uso de medicações antifator de necrose tumoral alfa (TNF-α) e presença do HLA-B27. Métodos Estudo retrospectivo com 100 pacientes com diagnóstico de espondiloartrites pelo critério Assessment of SpondyloArthritis International Society (ASAS) e 50 controles. Foram coletados nos prontuários dos pacientes, dados epidemiológicos, clínicos, exames de atividade inflamatória, presença do HLA-B27, e uso de medicamentos. A atividade de doença foi avaliada pelo Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Todos foram submetidos a eletrocardiograma realizado com aparelho de 12 derivações, sendo analisados ritmo, frequência cardíaca, distúrbios de condução e intervalo QT corrigido pela fórmula de Bazett. Resultados Dos 100 pacientes com espondiloartrites, 49 não usavam anti-TNF-α e 51 utilizavam este medicamento. O HLA-B27 estava presente em 53,1% da amostra. A frequência cardíaca foi mais baixa (p=0,06), o intervalo QT foi mais prolongado (p<0,0001) e existia mais perturbação de condução do ramo direito (p=0,014) nos pacientes com espondiloartrites do que nos controles. Uma modesta correlação de tempo de doença com frequência cardíaca foi encontrada (Rho=0,26; IC95%: 0,06-0,44; p=0,008). A presença do HLA-B27 aumentou a prevalência de perturbação de condução do ramo direito. Nenhum dos parâmetros eletrocardiográficos analisados alterou-se com uso de anti-TNF-α. Conclusão Pacientes com espondiloartrites tiveram frequência cardíaca menor, maior intervalo QT e prevalência maior de perturbação de condução do ramo direito do que controles. O HLA-B27 influi no aparecimento de perturbação de condução do ramo direito. O uso de anti-TNF-α não influiu nos achados eletrocardiográficos.

Screening of Inflammatory Bowel Disease and Spondyloarthritis for Referring Patients Between Rheumatology and Gastroenterology. / Criterios de cribado de enfermedad inflamatoria intestinal y espondiloartritis para derivación de pacientes entre Reumatología y Gastroenterología.

OBJECTIVE: To define clinical screening criteria for spondyloarthritis (SpA) in patients with inflammatory bowel disease (IBD) and vice versa, which can be used as a reference for referring them to the rheumatology or gastroenterology service. METHOD: Systematic literature review and a two-round Delphi method. The scientific committee and the expert panel were comprised of 2 rheumatologists and 2 gastroenterologists, and 7 rheumatologists and 7 gastroenterologists, respectively. The scientific committee defined the initial version of the criteria, taking into account sensitivity, specificity, standardization and ease of application. Afterwards, members of the expert panel assessed each item in a two-round Delphi survey. Items that met agreement in the first or second round were included in the final version of the criteria. RESULTS: Positive screening for SpA if at least one of the following is present: onset of chronic low back pain before 45 years of age; inflammatory low back pain or alternating buttock pain; HLA-B27 positivity; sacroiliitis on imaging; arthritis; heel enthesitis; dactylitis. Positive screening for IBD in the presence of one of the major criteria or at least two minor criteria. Major: rectal bleeding; chronic diarrhea with organic characteristics; perianal disease. Minor: chronic abdominal pain; iron deficiency anemia or iron deficiency; extraintestinal manifestations; fever or low grade fever, of unknown origin and duration >1week; unexplained weight loss; family history of IBD. CONCLUSION: Screening criteria for IBD in patients with SpA, and vice versa, have been developed. These criteria will be useful for early detection of both diseases.

Spondyloarthropathy: diagnostic imaging criteria for the detection of sacroiliitis / Espondiloartropatias: critérios de ressonância magnética na detecção da sacroileíte

Abstract Diagnostic imaging is crucial to the diagnosis and monitoring of spondyloarthropathies. Magnetic resonance imaging is the most relevant tool for the early detection of sacroiliitis, allowing the institution of therapeutic strategies to impede the progression of the disease. This study illustrates the major criteria for a magnetic resonance imaging-based diagnosis of spondyloarthropathy. The cases selected here present images obtained from the medical records of patients diagnosed with sacroiliitis over a two-year period at our facility, depicting the active and chronic, irreversible forms of the disease. Although computed tomography and conventional radiography can also identify structural changes, such as subchondral sclerosis, erosions, fat deposits, and ankylosis, only magnetic resonance imaging can reveal active inflammatory lesions, such as bone edema, osteitis, synovitis, enthesitis, and capsulitis.

Resumo A avaliação por imagem é fundamental para o diagnóstico e acompanhamento clínico dos pacientes com espondiloartropatias. A ressonância magnética é o método de imagem mais importante para a detecção precoce de sacroileíte, permitindo a instituição de terapias que podem impedir a progressão da doença. Este estudo ilustra os principais critérios de ressonância magnética na definição de sacroileíte nas espondiloartropatias, com imagens selecionadas dos prontuários dos pacientes diagnosticados no nosso serviço, demonstrando tanto os achados da doença em atividade como as alterações crônicas de caráter irreversível. Embora a tomografia computadorizada e a radiografia convencional possam identificar lesões estruturais crônicas, tais como esclerose subcondral, erosões, depósitos de gordura e anquilose, apenas a ressonância magnética é capaz de demonstrar lesões inflamatórias ativas, tais como edema ósseo, osteíte, sinovite, entesite e capsulite.

Inmunogenética de las espondiloartropatías / Immunogenetics of spondylo-arthropathies

Las espondiloartropatías son la segunda causa más frecuente de artritis inflamatorias autoinmunes en los humanos. Los antígenos HLA-B27, codificados por genes ubicados en el brazo corto del cromosoma 6, han sido señalados como un marcador genético diagnóstico de estas enfermedades, por su alta asociación; sin embargo, su papel en la inmunopatogenia ha sido polémico y contradictorio, ya que siendo elementos claves en la defensa frente a agentes externos, o extraños al organismo, se involucran en una respuesta autoinmune. Se realizó una revisión bibliográfica con el objetivo de profundizar en la inmunogenética de las espondiloartropatías, haciendo énfasis en el papel del HLA-B27. Se presentan las hipótesis más documentadas de la participación de este antígeno en la patogenia de las espondiloartropatías, teniendo en cuenta enfoques que van desde la genética hasta la bioquímica; así como, propiedades dinámicas estructurales del complejo HLA-B27-péptido. La revisión permite un mejor entendimiento de la etiopatogenia de las espondiloartropatías, sus manifestaciones clínicas y, de manera especial, la apertura de perspectivas terapéuticas (AU)

Spondylo-arthropathies are the second most frequent cause of autoimmune inflammatory arthritis in human beings. HLA-B27 antigens, coded by genes located in the shorter arm of chromosome 6, have been pointed out as a genetic marker for the diagnosis of these diseases because of its high as sociation. However, its role within immuno-pathogenesis has been controversial and contradictory; based on the fact of being key elements in the defense against bodies foreign to the organism, they are involved in an autoimmune response. This literature review has been carried out with the objective to deepen into the immunogenetics of spondylo-arthropathies, making emphasis on the role of HLA-B27. The most documented hypotheses on the presence of HLA-B27 in the pathogenesis of spondylo-arthropathies were presented, taking into account approaches ranging from genetics to biochemistry, as well as the structural dynamic properties of the HLA B27-peptide complex.

Acute myopericarditis as primary manifestation of urogenital reactive arthritis by Staphylococcus haemolyticus metilcilino resistant / Miopericarditis aguda como manifestación primaria de artritis reactiva urogenital por Staphylococcus haemolyticus resistente a meticilina

Reactive arthritis describes the relationship between the host and the environment. This leads to urogenital or gastrointestinal infections. It clinically presents with inflammatory lumbosacral pain, asymmetric oligoarthritis and enthesitis of the Achilles tendon and plantar fascia. Among the extra-articular manifestations are acute anterior uveitis, skin lesions, genital lesions, and oral ulcers, with the rarest being cardiovascular. A case is presented of a patient with a urogenital infection and cardiovascular manifestations, interpreted and managed as acute coronary syndrome. After further studies an acute myopericarditis was considered as a primary manifestation of reactive arthritis.

La artritis reactiva describe la interrelación entre el hospedero y el medio ambiente. Aparece después de infecciones urogenitales o digestivas. Clínicamente presenta dolor lumbosacro inflamatorio, oligoartritis asimétrica y entesitis del tendón de Aquiles y la fascia plantar. Entre las manifestaciones extraarticulares, se encuentran la uveítis anterior aguda, lesiones en piel, lesiones genitales y úlceras orales. Las más infrecuentes son las cardiovasculares. Describimos el caso de un paciente con infección urogenital y manifestaciones cardiovasculares interpretadas y manejadas como síndrome coronario agudo, pero que a la luz de estudios posteriores se consideró finalmente una miopericarditis aguda como manifestación primaria de una artritis reactiva.

Introdução: As espondiloartropatias formam um grupo de doenças distintas com características comuns, entre elas estão a espondilite anquilosante, artrite psoriática, artrite reativa e artrite enteropática. Caracterizam-se como doenças crônicas inflamatórias, e incluem uma variedade de características clínicas e genéticas, dentre essas está a associação com o antígeno HLA-B27. Objetivos: O estudo objetivou revisar na literatura informações sobre a abordagem fisioterapêutica na dor crônica nos indivíduos portadores de espondiloartropatias. Métodos: 26 artigos foram selecionados manualmente nas línguas portuguesa e inglesa indexados nas bases de dados eletrônicos SciELO, LILACS, e Pubmed partindo dos descritores Espondiloartropatias, Espondilite Anquilosante, Artrite Reativa, Artrite Psoriásica em cruzamento com a palavra chave Fisioterapia, de acordo com os Descritores em Ciências da Saúde (DeCS). Resultados: Foram analisados 178 artigos dos quais 147 artigos foram excluídos por não se enquadrarem nos critérios de seleção e 26 preencheram os critérios de inclusão, permitindo a fundamentação teórica e problemática do assunto pesquisado. Conclusão: O diagnóstico precoce juntamente com a cinesioterapia - com ênfase à hidrocinesioterapia - demonstra redução da dor, melhora na capacidade funcional, melhora da amplitude de movimento, diminuição do quadro inflamatório e melhora da qualidade de vida.

Introduction: Spondyloarthropathies form a group of different diseases with common characteristics, among them are ankylosing spondylitis, psoriatic arthritis, reactive arthritis and arthritis enteropathic. Are characterized as chronic inflammatory diseases, including a variety of clinical and genetic characteristics, among these is the association with the HLA-B27 antigen. Objectives: The aim of this study was to review the literature about the physical therapy approach to chronic pain in patients with spondyloarthritis. Méthods: We selected 26 articles, which were manually consulted in Portuguese and English indexed in electronic databases SciELO, LILACS and PubMed starting from descriptors Espondiloartropatias, Espondilite Anquilosante, Artrite Reativa, Artrite Psoriásica crossed with keyword Fisioterapia, all according to the Descriptors in Health Sciences (DeCS). Results: We analyzed 178 articles of which 147 articles were excluded because they do not fit the selection criteria and 26 met the inclusion criteria, allowing the theoretical foundation and problems of researched subject.

Espondiloartropatía juvenil: una visión desde la pediatría / Juvenile spondyloarthropathy: a view from pediatrics

La espondiloartropatía juvenil (EAPj) representa un grupo de artropatías crónicas que se inician en la infancia y que corresponden a entidades cuyas clasificaciones se han modificado en el transcurso de las décadas. Las clasificaciones actuales las incluyen sólo parcialmente. Las manifestaciones clínicas incluyen compromiso articular periférico asimétrico, entesis, sacroilíaco y menos frecuentemente de columna han permitido agruparlas en cinco categorías entre el que se encuentra la forma anquilosante juvenil relacionada con HLA B27 (+), el prototipo de EAPj y que podría representar a la forma de inicio de espondiloartropatía anquilosante del adulto. Los recientes avances en los estudios genéticos, en la patogenia, el desarrollo de mejores técnicas de imagenología tales como la ecografía musculo-esquelética y resonancia magnética aplicada a la Reumatología pediátrica podrían contribuir a generar criterios de clasificación de manera tal que faciliten la comunicación científica con los Reumatólogos de adultos. Un diagnóstico precoz, la aplicación de medidas de actividad de la enfermedad validadas y el oportuno manejo terapéutico obtendrán un pronóstico más favorable. Los resultados terapéuticos en EAPj presentan evidencia limitada aún requiriéndose mayor tiempo de evolución para obtener resultados a largo plazo.

Juvenile spondyloarthropathy (EAPj) represents a heterogeneous group of juvenile articular inflammatory entities and their classification have been changed during the last decades. The current classifications include only partially. The clinical manifestations of diseases involves peripheral joints, enthesis, sacroiliac and less frequently spine and they are classified in five specific subgroups among which is the juvenile ankylosing HLA B27 (+); the EAPj’s prototype and that may represent one of ankylosing spondyloarthropathy adult diseases. Recently, novel insights into the epidemiology, pathogenesis, and development of the imaging techniques such as muscle-skeletal ultrasound and magnetic resonance applied to pediatric rheumatology could be contributing to new classification criteria in order to facilitate the scientific communication with Rheumatologist of adult patients. An early diagnosis a validated measures of disease activity and treatment can change the course and outcome of disease.

[Effects of an exercise and relaxation aquatic program in patients with spondyloarthritis: A randomized trial]. / Efectos de un programa de ejercicio físico y relajación en el medio acuático en pacientes con espondiloartritis: ensayo clínico aleatorizado.

BACKGROUND AND OBJECTIVE: Spondyloarthritis is a general term referring to a group of chronic rheumatic illnesses that share clinical, genetic, radiological and epidemiological features. The clinical presentation of spondyloarthritis is characterized by the compromise of both the axial and peripheral articular skeleton. We aimed to evaluate the efficacy of an aquatic exercise plus relaxation program in patients with spondyloarthritis. PATIENTS AND METHOD: This was a randomized single blind study including 30 patients with spondylitis who were randomly assigned to an experimental or control group. For 2 months, the experimental group underwent an aquatic fitness plus relaxation program (3 sessions per week). Evaluations were also performed in the control group the same days as the experimental group but they did not participate in any supervised exercise program. The following data were obtained at baseline and immediately after application of the last session: Bath Ankylosing Spondylitis Functional Index, Bath Ankylosing Spondylitis Disease Activity Index, Health Questionnaire SF-12 and Sigma PC3(®) (Sigma-Elektro GmbH, Neustadt, Germany) Heart Rate Monitor. RESULTS: The Mann-Whitney test showed statistically significant differences in the quality of life (physical function [P=.05]), Bath Ankylosing Spondylitis Functional Index (P=.015), Bath Ankylosing Spondylitis Disease Activity Index (fatigue [P=.032], neck pain, back and hips [P=.045], pain or swelling in other joints [P=.032] and in waking morning stiffness [P=.019]). CONCLUSIONS: The results of the present study suggest that therapy with physical exercise plus relaxation provides benefits to spondyloarthritis patients and these are advised as a part of their usual treatment.
