Espondiloartrosis cervical e hipertrofia del ligamento amarillo / Cervical Spondyloarthrosis and Hypertrophy of the Yellow Ligament

RESUMEN Introducción: La espondiloartrosis cervical es una enfermedad articular crónica degenerativa, es la afección articular más frecuentemente observada en la población madura y una de las principales causas de discapacidad en todo el mundo, por lo que es importante el diagnóstico y tratamiento en las fases tempranas. Objetivo: Informar un caso clínico representativo de espondiloartrosis cervical e hipertrofia del ligamento amarillo. Presentación del caso: Paciente femenina de 49 años que seis años atrás sufrió una caída, y se golpeó el occipucio contra la pared, lo que le provocó pérdida transitoria del conocimiento y dolor en la región cervical; tres años después comenzó con limitación a los movimientos laterales del cuello, malestar y dolor sordo, referido a la nuca y al cuello. Conclusiones: El diagnóstico de espondiloartrosis cervical e hipertrofia del ligamento amarillo representa un desafío clínico, por lo poco común de la enfermedad a esta edad. El caso presentado es una paciente con alteraciones estructuradas en el esqueleto axial y gran repercusión anatómica y funcional debido a un relativo diagnóstico tardío, con evolución insatisfactoria. Por tanto, conviene conocer la enfermedad para realizar una detección precoz y ofrecer mejor atención terapéutica(AU)

ABSTRACT Introduction: Cervical spondyloarthrosis is a chronic degenerative joint disease, it is the most frequent joint condition in the mature population and one of the main causes of disability throughout the world, so diagnosis and treatment in the early stages are important. Objective: To report a representative clinical case of cervical spondyloarthrosis and hypertrophy of the yellow ligament. Case presentation: A 49-year-old female patient suffered a fall six years ago, hitting her occiput against the wall, causing her temporary loss of consciousness and pain in the cervical region. Three years later, she began with limitation of lateral neck movements, discomfort and dull pain, referred to the nape and neck. Conclusion: The diagnosis of cervical spondyloarthrosis and hypertrophy of the yellow ligament represents a clinical challenge, due to the rare nature of the disease at this age. The case reported is a patient with structured alterations in the axial skeleton and great anatomical and functional repercussions due to a relatively late diagnosis, with unsatisfactory evolution. Therefore, it is convenient to know the disease in order to early detect it and to offer better therapeutic care(AU)

The Brazilian Society of Rheumatology guidelines for axial spondyloarthritis - 2019

Abstract Spondyloarthritis is a group of chronic inflammatory systemic diseases characterized by axial and/or peripheral joints inflammation, as well as extra-articular manifestations. The classification axial spondyloarthritis is adopted when the spine and/or the sacroiliac joints are predominantly involved. This version of recommendations replaces the previous guidelines published in May 2013. A systematic literature review was performed, and two hundred thirty-seven studies were selected and used to formulate 29 recommendations answering 15 clinical questions, which were divided into four sections: diagnosis, non-pharmacological therapy, conventional drug therapy and biological therapy. For each recommendation the level of evidence supporting (highest available), the strength grade according to Oxford, and the degree of expert agreement (inter-rater reliability) is informed. These guidelines bring evidence-based information on clinical management of axial SpA patients, including, diagnosis, treatment, and prognosis.

Abordaje práctico de la espondiloartritis / Practical approach to spondyloarthritis

Introducción: la espondiloartritis, es una forma de artritis inflamatoria que, generalmente comienza entre los 17 y los 45 años. La inflamación sistémica es una característica clave que ayuda a distinguirla de otros tipos de artritis, incluida la artritis por desgaste y desgarro, como la osteoartritis. Objetivo: brindar información sobre el abordaje práctico de la espondiloartritis para contribuir a esclarecer puntos que, a juicio de los autores de este trabajo, son importantes para el manejo de la misma. Desarrollo: en poco tiempo han tenido lugar inusitados avances que abarcan todos los aspectos de su manejo, incluidos el diagnóstico y el seguimiento, pero sobre todo en su tratamiento. Algunas presentaciones engañosas son propias del comienzo retardado, como la espondiloartritis periférica de inicio tardío (LOPS), que se caracteriza por una oligoartritis inflamatoria que contrasta con los signos generales, un importante síndrome inflamatorio y, a veces, edema asimétrico de las extremidades inferiores. Conclusiones: el papel de los reumatólogos es esencial en el manejo de esta enfermedad, pues son los especialistas mejor calificados para tener a su cargo a estos pacientes, mientras que los generalistas participan más en la detección de la misma(AU)

Introduction: spondyloarthritis, or SpA, is a form of inflammatory arthritis that usually begins between 17 and 45 years. Systemic inflammation is a key feature that helps distinguish it from other types of arthritis, including arthritis by tearing and tearing, such as osteoarthritis. Objective: to provide information on the practical approach of spondyloarthritis to help clarify points that, in the opinion of the authors of this work, are important for the management of it. Development: in a short time, there have been unusual advances that cover all aspects of its management, including diagnosis and monitoring, but especially in its treatment. Some deceptive presentations are typical of delayed onset, such as late-onset peripheral spondyloarthritis (LOPS), which is characterized by an inflammatory oligoarthritis that contrasts with the general signs, an important inflammatory syndrome and, sometimes, asymmetric edema of the lower extremities. Conclusions: the role of rheumatologists is essential in the management of this disease, as they are the best qualified specialists to be in charge of these patients, while the generalists participate more in the detection of it(AU)

Análise da frequência de uveítes em pacientes com espondiloartrites, suas complicações e associação com parâmetros clínicos da doença / Analysis of the frequency of uveitis in spondyloarthritis patients and associations with clinical parameters of the disease

Resumo Objetivo: A uveíte anterior aguda é a principal manifestação extra-articular na espondiloartrite. O objetivo deste estudo foi analisar se a presença da uveíte se associa com diferentes manifestações clínicas, laboratoriais, radiológicas e a terapêutica nos pacientes com espondiloartrite. Métodos: Estudo observacional retrospectivo realizado com 153 pacientes portadores de espondiloartrite atendidos no período de 1997 a 2017 na Grande Florianópolis, Brasil. Foram analisados dados demográficos, laboratoriais, clínicos e do tratamento de pacientes com espondiloartrite em relação a presença ou não de uveíte. Resultados: A uveíte foi encontrada em 26,8% dos pacientes. A presença de complicações foi rara, ocorrendo catarata em somente quatro pacientes e glaucoma em dois deles. Foi observada uma tendência a maior frequência de uveíte anterior aguda no sexo masculino (p=0,06), nos pacientes com história familiar (p=0,19) e HLA-B27 positivos (p=0,14). Pacientes com espondiloartrite e uveíte mais frequentemente usavam anti-TNF (p=0,04) e apresentavam sacroiliite em exames de imagem (p=0,02). Não observou-se associação entre a uveíte e o acometimento cardiovascular (p=0,44), cutâneo (p=0,13) ou gastrointestinal (p=0,10). Conclusão: A uveíte que ocorre em pacientes com espondiloartrite é comum, tem predomínio no sexo masculino e é mais frequente em pacientes com HLA-B27 positivo. O uso de imunobiológicos como o anti-TNF é frequente nos pacientes com uveíte.

Abstract Objective: Acute anterior uveitis (AAU) is the most common extra-articular manifestation of spondyloarthritis. The aim of this study is to analyze if the presence of uveitis is associated with a diferent clinical manifestation, laboratorial, radiological and therapetiuc among spondyloarthritis patients. Methods: This was a observational retrospective study with 153 patients with spondyloarthritis attended in the period from 1997 to 2017 in Florianopolis, Brazil. It was analyzed demografical, laboratorial, clinical and therapeutic data in spondyloarthritis patients with or without uveitis. Results: 26,8% of the patients with spondyloarthritis presented uveitis. The presence of complications was rare, with cataract occurring in only four patients and glaucoma in two of them. A higher frequency of acute anterior uveitis in males (p = 0.06) was observed in patients with a family history (p = 0.19) and HLA-B27 positive (p = 0.14). Patients with spondyloarthritis and uveitis more frequently used anti-TNF (p = 0.04) and presented sacroiliitis on imaging tests (p = 0.02). There was no association between uveitis and cardiovascular (p = 0.44), cutaneous (p = 0.13) or gastrointestinal involvement (p = 0.10). Conclusion: Uveitis in patients with spondylarthritis is common, predominantly in males, and more frequently in HLA-B27 positive patients. The use of immunobiological agents such as anti-TNF is common in patients with uveitis.

Candida arthritis in a patient diagnosed with spondyloarthritis

Abstract Candida arthritis is an unusual manifestation that usually affects the knees. A 35-year-old man presented with a 2-month history of pain and swelling in the right knee. Swelling persisted after anti-inflammatory treatment. Peripheric spondyloarthritis was considered, but methotrexate, sulfasalazine, and methylprednisolone did not reduce the swelling. Direct examination of synovial fluid and a culture were positive for Candida albicans. Intravenous and intra-articular amphotericin-B were administered. The arthritis regressed and a culture and direct staining showed negative results. Candida arthritis should be considered in patients with arthritis that is resistant to treatment and prolonged, even if risk factors are absent.

Espondiloartritis anquilosante: revisión de hallazgos imagenológicos en la columna / Ankylosing spondyloarthritis: review of spinal imaging findings

Abstract: Introduction. Ankylosing spondyloarthritis (AS) is the most common and representative of seronegative spondyloarthropathy. It is characterised by chronic inflammation of the axial skeleton, leading to chronic back pain and progressive stiffness. It typically occurs in young patients, with symptoms often appearing with peak onset between 20 and 30 years of age, and is strongly associated with human leukocyte antigen B-27 (HLA B-27). Current imaging techniques are central in the management of these patients. The recognition of its classic imaging findings and its complications is essential for radiologists. Objectives. To present a pictorial review of the spinal imaging findings in patients with AS. Methods and materials. An analysis will be made of the spinal imaging findings in conventional radiography, CT and MRI in multiple patients from our medical centre. The most representative findings, complications, differential diagnoses, and some radiological key points will be shown.

Resumen: Introducción. La espondilitis anquilosante (EA) es la artropatía seronegativa más común y representativa. Se caracteriza por inflamación crónica del esqueleto axial, dolor referido a la columna vertebral de tipo inflamatorio y rigidez progresiva. Típicamente se manifiesta en pacientes jóvenes que inician su sintomatología entre los 20-30 años de edad y está ligada al antígeno leucocitario humano B-27 (HLA B-27). Las imágenes son fundamentales en el manejo de estos pacientes. Es deber del radiólogo reconocer los hallazgos imagenológicos presentes. Objetivos. Realizar una revisión pictográfica de hallazgos imagenológicos presentes en la columna vertebral de pacientes portadores de EA. Material y método. Análisis de las manifestaciones imagenológicas de columna más representativas de la EA en pacientes de nuestro centro en radiografía convencional, TC y RM, junto con posibles complicaciones y diagnósticos diferenciales.

Mercury Exposure in a Riverside Amazon Population, Brazil: A Study of the Ototoxicity of Methylmercury

Introduction Mercury poisoning causes hearing loss in humans and animals. Acute and long-term exposures produce irreversible peripheral and central auditory system damage, and mercury in its various forms of presentation in the environment is ototoxic. Objective We investigated the otoacoustic emissions responses in a riverside population exposed to environmental mercury by analyzing the inhibitory effect of the medial olivocochlear system (MOCS) on transient otoacoustic emissions (TEOAE). Methods The purpose of the research was to evaluate the entire community independently of variables of sex and age. All of the participants were born and lived in a riverside community. After otolaryngologic evaluation, participants were received tympanometry, evaluation of contralateral acoustic reflexes, pure tone audiometry, and recording of TEOAEs with nonlinear click stimulation. Hair samples were collect to measure mercury levels. Results There was no significant correlation between the inhibitory effect of the MOCS, age, and the level of mercury in the hair. Conclusions The pathophysiological effects of chronic exposure may be subtle and nonspecific and can have a long period of latency; therefore, it will be important to monitor the effects of mercury exposure in the central auditory system of the Amazon population over time. Longitudinal studies should be performed to determine whether the inhibitory effect of the MOCS on otoacoustic emissions can be an evaluation method and diagnostic tool in populations exposed to mercury. .

Avaliação do desempenho do BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) numa coorte brasileira de 1492 pacientes com espondiloartrites: dados do Registro Brasileiro de Espondiloartrites (RBE) / Evaluation of performance of BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) in a Brazilian cohort of 1492 patients with spondyloarthritis: data from the Brazilian Registry of Spondyloarthritides (RBE)

Objetivo Avaliar os resultados da aplicação do Índice de Atividade de Doença da Espondilite Anquilosante de Bath (BASDAI) numa série de pacientes brasileiros com EpA e estabelecer suas correlações com as variáveis específicas do grupo. Métodos Um protocolo comum de investigação foi prospectivamente aplicado em 1.492 pacientes brasileiros classificados como EpA pelos critérios do Grupo Europeu de Estudo das Espondiloartropatias (ESSG), acompanhados em 29 centros de referência em reumatologia no Brasil. Variáveis clínicas, demográficas e índices de doença foram colhidos. Os valores totais do BASDAI foram comparados com a presença das diferentes variáveis. Resultados O valor médio do BASDAI foi de 4,20 ± 2,38. Os escores médios do BASDAI foram mais elevados nos pacientes com forma clínica combinada, comparado às formas axiais e periféricas isoladas, nos pacientes do sexo feminino e nos sedentários. Com relação ao componente axial, valores mais altos do BASDAI estiveram significativamente associados à lombalgia inflamatória, à dor alternante em nádegas, à dor cervical e ao acometimento de coxofemorais. Houve associação estatística entre os valores do BASDAI e o comprometimento periférico, relacionado ao número de articulações inflamadas, tanto dos membros inferiores quanto dos membros superiores, e às entesites. A positividade do HLA-B27 e a presença de manifestações extra-articulares não estiveram correlacionadas com os valores médios do BASDAI. Valores mais baixos do BASDAI estiveram associados ao uso de agentes biológicos (p < 0,001). Conclusão Nesta série heterogênea de pacientes brasileiros com EpA, o BASDAI conseguiu demonstrar “atividade de doença” tanto nos pacientes com acometimento axial quanto naqueles com envolvimento periférico. .

Objective To analyze the results of the application of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) in a large series of Brazilian patients with the diagnosis of SpA and establish its correlations with specific variables into the group. Methods A common protocol of investigation was prospectively applied to 1492 Brazilian patients classified as SpA according to the European Spondyoarthropathies Study Group (ESSG), attended at 29 referral centers of Rheumatology in Brazil. Clinical and demographic variables, and disease indices (BASDAI, Basfi, Basri, Mases, ASQol) were applied. The total values of BASDAI were compared to the presence of the different variables. Results The mean score of BASDAI was 4.20 ± 2.38. The mean scores of BASDAI were higher in patients with the combined (axial + peripheral + entheseal) (4.54 ± 2.38) clinical presentation, compared to the pure axial (3.78 ± 2.27) or pure peripheral (4.00 ± 2.38) clinical presentations (P < 0.001). BASDAI also presented higher scores associated with the female gender (P < 0.001) and patients who did not practice exercises (P < 0.001). Regarding the axial component, higher values of BASDAI were significantly associated with inflammatory low back pain (P < 0.049), alternating buttock pain (P < 0.001), cervical pain (P < 0.001) and hip involvement (P < 0.001). There was also statistical association between BASDAI scores and the peripheral involvement, related to the lower (P = 0.004) and upper limbs (P = 0.025). The presence of enthesitis was also associated to higher scores of BASDAI (P = 0.040). Positive HLA-B27 and the presence of cutaneous psoriasis, inflammatory bowel disease, uveitis and urethritis were not correlated with the mean scores of BASDAI. Lower scores of BASDAI were associated with the use of biologic agents (P < 0.001). Conclusion In this heterogeneous Brazilian series of SpA patients, BASDAI was able to demonstrate “disease ...

Artrite enteropática no Brasil: dados do registro brasileiro de espondiloartrites / Enteropathic arthritis in Brazil: data from the brazilian registry of spondyloarthritis

As doenças inflamatórias intestinais (doença de Crohn e retocolite ulcerativa) apresentam manifestações extraintestinais em um quarto dos pacientes, sendo a mais comum a artrite enteropática. MÉTODOS: Estudo prospectivo, observacional e multicêntrico, realizado com pacientes de 29 centros de referência participantes do Registro Brasileiro de Espondiloartrites (RBE), que se incorpora ao grupo RESPONDIA (Registro Ibero-americano de Espondiloartrites). Dados demográficos e clínicos de 1472 pacientes foram colhidos, e aplicaram-se questionários padronizados de avaliação de mobilidade axial, de qualidade de vida, de envolvimento entesítico, de atividade de doença e de capacidade funcional. Exames laboratoriais e radiográficos foram realizados. Objetivamos, neste presente artigo, comparar as características clínicas, epidemiológicas, genéticas, imagenológicas, de tratamento e prognóstico de enteroartríticos com os outros espondiloartríticos nesta grande coorte brasileira. RESULTADOS: Foram classificados como enteroartrite 3,2% dos pacientes, sendo que 2,5% tinham espondilite e 0,7%, artrite (predomínio periférico). O subgrupo de indivíduos com enteroartrite apresentava maior prevalência de mulheres (P < 0,001), menor incidência de dor axial inflamatória (P < 0,001) e de entesite (P = 0,004). O HLA-B27 foi menos frequente no grupo de enteroartríticos (P = 0,001), mesmo se considerado apenas aqueles com a forma axial pura. Houve menor prevalência de sacroiliíte radiológica (P = 0,009) e também menor escore radiográfico (BASRI) (P = 0,006) quando comparado aos pacientes com as demais espondiloartrites. Também fizeram mais uso de corticosteroides (P < 0,001) e sulfassalasina (P < 0,001) e menor uso de anti-inflamatórios não hormonais (P < 0,001) e metotrexato (P = 0,001). CONCLUSÃO: Foram encontradas diferenças entre as enteroartrites e as demais espondiloartrites, principalmente maior prevalência do sexo feminino, menor frequência do HLA-B27, associados a uma menor gravidade do acometimento axial.

Inflammatory bowel diseases (Crohn's disease and ulcerative rectocolitis) have extraintestinal manifestations 25% of the patients, with the most common one being the enteropathic arthritis. METHODS: Prospective, observational, multicenter study with patients from 29 reference centers participating in the Brazilian Registry of Spondyloarthritis (RBE), which incorporates the RESPONDIA (Ibero-American Registry of Spondyloarthritis) group. Demographic and clinical data were collected from 1472 patients and standardized questionnaires for the assessment of axial mobility, quality of life, enthesitic involvement, disease activity and functional capacity were applied. Laboratory and radiographic examinations were performed. The aim of this study is to compare the clinical, epidemiological, genetic, imaging, treatment and prognosis characteristics of patients with enteropathic arthritis with other types of spondyloarthritis in a large Brazilian cohort. RESULTS: A total of 3.2% of patients were classified as having enteroarthritis, 2.5% had spondylitis and 0.7%, arthritis (peripheral predominance). The subgroup of individuals with enteroarthritis had a higher prevalence in women (P < 0.001), lower incidence of inflammatory axial pain (P < 0.001) and enthesitis (P = 0.004). HLA-B27 was less frequent in the group with enteroarthritis (P = 0.001), even when considering only those with the pure axial form. There was a lower prevalence of radiographic sacroiliitis (P = 0.009) and lower radiographic score (BASRI) (P = 0.006) when compared to patients with other types of spondyloarthritis. They also used more corticosteroids (P < 0.001) and sulfasalazine (P < 0.001) and less non-steroidal anti-inflammatory drugs (P < 0.001) and methotrexate (P = 0.001). CONCLUSION: There were differences between patients with enteroarthritis and other types of spondyloarthritis, especially higher prevalence of females, lower frequency of HLA-B27, associated with less severe axial involvement.

Patología inflamatoria de columna en niños y adolescentes / Inflammatory spine pathology in children and adolescents

Chronic inflammatory axial pain is an uncommon pediatric syndrome, brings a number of diseases affecting the axial skeleton. It is characterized by unknown etiology, with recognizing genetic susceptibility factors. The medical clinician should be performed to establish the diagnosis, making accurate therapy for long-term success and working to get a good quality of life. Current classifications established for children and young patients forms are limited by the pediatric medical short follow-up age. Two international classifications (a) International League of Associations for Rheumatology and (b) Classification of juvenile spondyloarthropathies Spondylarthropathy European group Study Group to achieve approximate diagnosis for pediatric rheumatology forms. The adult rheumatologist usually who will establish the definitive diagnosis and prognosis. The chronic inflammatory axial pain needs an unification of classification criteria for children and adults in order to facilitate the scientific communication and medical transition.

El dolor axial inflamatorio crónico es una entidad infrecuente en Pediatría, y agrupa una serie de patologías que afectan el esqueleto axial. este grupo de enfermedades son de etiología aún desconocida, reconociendo factores de susceptibilidad genética en ellas. Su importancia está en el enfoque que el clínico debe realizar para establecer el diagnóstico, realizar una terapia precoz para obtener buenos resultados a largo plazo y procurar que el paciente obtenga una buena calidad de vida. Las clasificaciones actuales establecidas para las formas infantojuveniles se ven limitadas por lo breve del periodo de seguimiento etario, además que se hace necesario aplicar dos clasificaciones internacionales (a) International League of Associations for Rheumatology y (b) Clasificación de Espondiloartropatías Juveniles del European Spondyloarthropathy Study Group para lograr el diagnóstico aproximado. Es necesario considerar que en muchos casos será el reumatólogo de adultos quien establecerá el diagnóstico y pronóstico definitivo. Se reconoce que este grupo de patología inflamatoria crónica requiere unificación de criterios de clasificación en niños y adultos para facilitar la comunicación científica y de transición.

Baixa prevalência das manifestações extra-articulares renais, cardíacas, pulmonares e neurológicas nas espondiloartrites: análise do Registro Brasileiro de Espondiloartrites / Low prevalence of renal, cardiac, pulmonary, and neurological extra-articular clinical manifestations in spondyloarthritis: analysis of the Brazilian Registry of Spondyloarthritis

OBJETIVO: Descrever as manifestações extra-articulares (cardíacas, renais, pulmonares e neurológicas) geralmente não relacionadas às espondiloartrites (EpA) em uma grande coorte de pacientes brasileiros. MÉTODOS: Este estudo retrospectivo analisou 1.472 pacientes com o diagnóstico de EpA atendidos em 29 centros distribuídos pelas cinco principais regiões geográficas do Brasil, integrantes do Registro Brasileiro de Espondiloartrites. Todos os pacientes foram avaliados para a prevalência das principais manifestações extra-articulares (cardíacas, renais, pulmonares e neurológicas), divididas por diagnóstico [espondilite anquilosante (EA), artrite psoriásica (AP), artrite reativa (ARe), artrite associada a doença inflamatória intestinal (DII), EpA indiferenciada (EI) e EpA juvenil] e por forma clínica (axial, periférica, mista e entesítica). RESULTADOS: Dentre os pacientes avaliados com EpA, 963 apresentavam EA, 271 AP, 49 ARe, 48 artrite associada a DII, 98 EI e 43 EpA juvenil. Acometimento cardíaco foi observado em 44 pacientes (3,0%), seguido por acometimento pulmonar em 19 (1,3%), renal em 17 (1,2%) e neurológico em 13 pacientes (0,9%). A maioria dos casos de acometimento visceral ocorreu nos pacientes com EA ou AP e naqueles com forma clínica mista (axial e periférica) e/ou predominantemente axial. CONCLUSÃO: As manifestações extra-articulares cardíacas, renais, pulmonares e neurológicas são muito pouco frequentes nas EpA, variando de 0,9%-3% nesta grande coorte brasileira, estando mais associadas a EA e AP.

OBJECTIVE: To describe the extra-articular manifestations (cardiac, renal, pulmonary, and neurological), usually not related to spondyloarthritis (SpA), in a large cohort of Brazilian patients. MATERIALS AND METHODS: This retrospective study analyzed 1,472 patients diagnosed with SpA and cared for at 29 health care centers distributed in the five major geographic regions in the country, participating in the Brazilian Registry of Spondyloarthritis (BRS). All patients were assessed for the prevalence of major extra-articular manifestations (cardiac, renal, pulmonary, and neurological), classified according to the diagnosis [ankylosing spondylitis (AS), psoriatic arthritis (PsA), reactive arthritis (ReA), arthritis associated with inflammatory bowel disease (IBD), undifferentiated spondyloarthritis (uSpA), and juvenile SpA], and according to the clinical presentation (axial, peripheral, mixed, and enthesitis). RESULTS: Of the patients with SpA assessed, 963 had AS, 271 PsA, 49 ReA, 48 arthritis associated with IBD, 98 uSpA, and 43 juvenile SpA. Cardiac involvement was reported in 44 patients (3.0%), pulmonary involvement in 19 (1.3%), renal involvement in 17 (1.2%), and neurological involvement in 13 patients (0.9%). Most patients with visceral involvement had AS or PsA, and the mixed (axial + peripheral) and/or predominantly axial clinical form. CONCLUSION: Cardiac, renal, pulmonary, and neurological extra-articular manifestations are quite infrequent in SpA, ranging from 0.9% to 3% in this large Brazilian cohort, and affected predominantly patients with AS and PsA.
