Does post-COVID reactive arthritis exist? Experience of a tertiary care centre with a review of the literature.

BACKGROUND: Rheumatological manifestations following COVID-19 are various, including Reactive Arthritis (ReA), which is a form of asymmetric oligoarthritis mainly involving the lower limbs, with or without extra-articular features. The current case series describes the clinical profile and treatment outcome of 23 patients with post-COVID-19 ReA. METHODS: A retrospective, observational study of patients with post-COVID-19 arthritis over one year was conducted at a tertiary care centre in India. Patients (n=23) with either a positive polymerase chain reaction test for SARS-CoV2 or an anti-COVID-19 antibody test were included. Available demographic details, musculoskeletal symptoms, inflammatory markers, and treatment given were documented. RESULTS: Sixteen out of 23 patients were female. The mean age of the patients was 42.8 years. Nineteen patients had had symptomatic COVID-19 infection in the past. The duration between onset of COVID-19 symptoms and arthritis ranged from 5 to 52 days with a mean of 25.9 days. The knee was the most involved joint (16 out of 23 cases). Seven patients had inflammatory lower back pain and nine had enthesitis. Most patients were treated with non-steroidal anti-inflammatory drugs (NSAIDs) and steroids - either depot injection or a short oral course. Three patients required treatment with hydroxychloroquine and methotrexate which were eventually stopped. No relapse was reported in any of the patients. CONCLUSION: On combining our data with 21 other case reports of ReA, a lower limb predominant, oligoarticular, asymmetric pattern of arthritis was seen with a female preponderance. The mean number of joints involved was 2.8. Axial symptoms and enthesitis were often coexistent. Treatment with NSAIDs and intra-articular steroids was effective. However, whether COVID-19 was the definitive aetiology of the arthritis is yet to be proven.

Antecedentes: Las manifestaciones reumatológicas posteriores al COVID-19 son diversas, entre ellas, la artritis reactiva, que es una forma de oligoartritis asimétrica que afecta principalmente a los miembros inferiores, con o sin características extraarticulares. La serie de casos actual describe el perfil clínico y el resultado del tratamiento de 23 pacientes con artritis reactiva posterior a COVID-19. Métodos: Se realizó un estudio observacional retrospectivo de pacientes con artritis post-COVID-19 durante un año en un centro de atención terciaria en India. Se incluyeron pacientes (n=23) con una prueba de reacción en cadena de la polimerasa positiva para SARS-CoV-2 o una prueba de anticuerpos anti-COVID-19. Se documentaron los detalles demográficos disponibles, los síntomas musculoesqueléticos, los marcadores inflamatorios y el tratamiento administrado. Resultados: Dieciséis de los 23 pacientes eran mujeres. La edad media de los pacientes fue de 42,8 años. Diecinueve pacientes habían tenido infección sintomática por COVID-19 en el pasado. La duración entre el inicio de los síntomas de COVID-19 y la artritis osciló entre 5 y 52 días, con una media de 25,9 días. La rodilla fue la articulación más comúnmente involucrada (16 de 23 casos). Siete pacientes tenían dolor lumbar inflamatorio y 9 tenían entesitis. La mayoría de los pacientes fueron tratados con medicamentos antiinflamatorios no esteroideos y esteroides, ya fuera una inyección de depósito o un ciclo oral corto. Tres pacientes requirieron tratamiento con hidroxicloroquina y metotrexato, que finalmente se suspendieron. No se reportaron recaídas en ninguno de los pacientes. Conclusión: Al combinar nuestros datos con otros 21 informes de casos de artritis reactiva, se observó un patrón de artritis oligoarticular asimétrico predominante en las extremidades inferiores con predominio femenino.(AU)

Artritis reactiva post-estreptocócica. Una revisión de literatura / Post-streptococcal reactive arthritis. A literature review

Introducción: existe un debate en la actualidad acerca de si la artritis reactiva post-estreptocócica es una entidad separada o una condición en el espectro de la fiebre reumática aguda. Objetivo: revisar la literatura existente sobre el tema artritis reactiva post-estreptocócica. Desarrollo : se realizó una búsqueda bibliográfica en Medline, Pubmed, Scielo y Dialnet, buscando como palabras clave: artritis y artritis reactiva post-estreptocócica. Además de la búsqueda computadorizada se realizó una búsqueda manual. Dichas bases de datos recogen las publicaciones más importantes en el campo científico de la medicina. La búsqueda se realizó en abril del 2018, y comprendió desde el año 1989 hasta la actualidad. Utilizamos el programa Reference Manager, versión 12, para crear una base de datos con las publicaciones, categorizarlas y filtrarlas de acuerdo a su relevancia para nuestro estudio. Se recabaron un total de 45 documentos en total, de los cuales fueron descartados unos 30, debido a su nivel de generalización y escasa especificidad en el tema abordado. Conclusiones: los signos clásicos de tumefacción, eritema, calor y dolor están presentes, siendo el dolor el más importante, está presente en reposo y aumenta con los movimientos. Como en la FR, la artritis postestreptocócica es una artritis reactiva caracterizada por una infección faríngeaestreptocócica, un intervalo libre y una posterior inflamación aséptica en una o más articulaciones(AU)

Introduction: there is currently debate about whether post-streptococcal reactive arthritis is a separate entity or condition in the spectrum of acute rheumatic fever. Objective: to review the existing literature on the topic post-streptococcal reactive arthritis. Development: a bibliographic search was carried out in Medline, Pubmed, Scielo and Dialnet, searching as keywords: arthritis and post-streptococcal reactive arthritis. In addition to the computerized search, a manual search was carried out. These databases collect the most important publications in the scientific field of medicine. The search was conducted in April 2018, and ran from 1989 to the present. We use the Reference Manager program, version 12, to create a database with publications, categorize them and filter them according to their relevance to our study. A total of 45 documents were collected, of which about 30 were discarded, due to their level of generalization and lack of specificity in the topic addressed. Conclusions: the classic signs of swelling, erythema, heat and pain are present, with pain being the most important, it is present at rest and increases with movements. As in RF, post-streptococcal arthritis is a reactive arthritis characterized by a pharyngeal-streptococcal infection, a free interval and subsequent aseptic inflammation in one or more joints(AU)

Enfermedad de Poncet: manifestación inusual de tuberculosis / Poncets disease: unusual manifestation of tuberculosis

Resumen LA enfermedad de Poncet es una poliartritis aséptica reactiva poco frecuente que ocurre durante cualquier etapa de una infección activa pulmonar o extrapulmonar por Mycobacterium tuberculosis. Existen apenas 200 casos descritos en la bibliografía y hasta el momento permanece como diagnóstico de exclusión sin patogenia bien definida. Suele responder rápida y satisfactoriamente al tratamiento antituberculoso sin dejar secuelas. Este artículo revisa la epidemiología, patogenia, manifestación clínica, diagnóstico, tratamiento y pronóstico de la enfermedad de Poncet.

Abstract Poncet's disease is a rarely reported aseptic reactive polyarthritis associated to active pulmonary or extrapulmonary infection caused by Mycobacterium tuberculosis. There are no more than 200 cases reported in the literature and still remains as a diagnosis of exclusion with unknown pathogenesis. It quickly and remarkably resolves with antituberculous drugs, has usually a good prognosis and does not turn into chronic arthritis. This article reviews the epidemiology, pathogenesis, clinical presentation, diagnosis, treatment options and prognosis of Poncet's disease.

Chronic arthritis in chikungunya virus infection. / Artritis crónica en la infección por virus de Chikunguña.

INTRODUCTION: Chikungunya virus infection causes arthralgia and arthritis in the acute phase of the disease but, in more than half of the cases, musculoskeletal manifestations can be prolonged over time and, in some cases, become chronic. Although polyarthralgia is the most frequent chronic manifestation, forms with polyarthritis, tenosynovitis and enthesopathy are also common. OBJECTIVE: To analyze the clinical characteristics of patients with persistent articular manifestations after infection with the Chikungunya virus. PATIENTS: Report of 3 cases of chronic arthritis after infection with chikungunya virus diagnosed at outpatient care in a university hospital of Catalonia, all of them imported after exposure in areas of epidemic infection between 2013-2015. RESULTS: All three patients had inflammatory joint pain for more than one year after acute disease (3, 2 and 1 years, respectively). In all cases, it appeared as polyarthritis with involvement of small joints of hands and feet (pseudorheumatoid arthritis-like). Laboratory tests showed a slight elevation of acute phase reactants, and analyses for immune markers were negative. Two of the patients required treatment with glucocorticoids and hydroxychloroquine. The course led to slow clinical improvement, but only one of them came to be completely asymptomatic. CONCLUSION: In the differential diagnosis of chronic polyarthritis, Chikungunya virus disease should also be considered in areas in which it is not endemic.

Evolution over thirty years of the profile of inpatients with reactive arthritis in a tertiary rheumatology unit.

Reactive arthritis (ReA) is sterile arthritis occurring after extra articular bacterial infection. The aim of this study was to analyze, over 30 years, clinical, biological and imaging characteristics as well as therapeutic management of new cases of ReA, comparing two periods. METHODS: retrospective monocentric study, data of all the patients followed in our unit between January 1st 1984 and April 2014 with the diagnosis or ReA were analyzed (clinical and biological features, management and outcome), and compared between two periods: from January 1984 to December 1993, and from January 2004 to December 2013. RESULTS: Sixty two patients fulfilling international diagnosis criteria were analyzed. There was no significant difference between the two periods in number of new cases, clinical presentation, biological data or outcome. Changes in therapeutic management were obvious with occurrence of anti TNF in the recent period. CONCLUSION: Reactive arthritis is still a current rheumatologic problem in a developed country, with a need of early and tailored rheumatologic management.

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.

[Tuberculous rheumatism "Poncet's disease". Case report]. / Reumatismo tuberculoso "enfermedad de Poncet". Reporte de caso.

BACKGROUND: Deaths due to tuberculosis have reached 2.5 million cases per year worldwide. Poncet's disease is an infrequent form of tuberculosis characterised by a clinical picture of polyarthritis. CLINICAL CASE: A 24-year-old male presented with morning stiffness, arthralgias, bilateral symmetric arthritis of the proximal interphalangeal joints, wrists, knees, ankles, and shoulders, and adenomegalies at the cervical, submandibular, left supraclavicular, axillary and inguinal levels, without fever. Laboratory results were as follows: ESR 44mm/h, C-reactive protein 4.35, normal levels of complement C3 and C4, negative rheumatoid factor and anticyclic citrullinated peptide antibodies, positive antinuclear antibodies with fine speckled pattern (1:320) and cytoplasm (1:160) pattern and negative anti-Smith, -double-stranded DNA, Sjogren's syndrome-antigen A and Sjogren's syndrome-antigen B. Histological report of cervical node tissue revealed granulomatous lesions compatible with tuberculosis. Rheumatoid arthritis and systemic lupus erythematosus were ruled out. Anti-tuberculosis agents were initiated that resolved the clinical picture. Diagnosis of Poncet's disease was confirmed. CONCLUSION: The differential diagnosis between tuberculosis and autoimmune inflammatory joint diseases is a clinical challenge.

Factores de riesgo de las enfermedades reumáticas en niños atendidos en el Hospital Pediátrico Provincial Mártires de Las Tunas / Risk factors of rheumatic diseases in children treated in Mártires de Las Tunas Provincial Pediatric Hospital

Fundamento: las afecciones reumáticas son enfermedades inflamatorias crónicas que producen invalidez y en ocasiones conducen a la muerte del paciente. En el Hospital Pediátrico Provincial Mártires de Las Tunas no existen antecedentes de estudios analíticos sobre las colagenosis, sin embargo, el número de casos ingresados por estas afecciones ha aumentado progresivamente, por esta razón se estudiaron los factores de riesgo con asociación causal de las colagenosis más frecuentes: artritis reactiva, lupus eritematoso y esclerodermia (AU)

Background: rheumatic affections are chronic inflammatory diseases that cause disability and occasionally lead to the patient's death. There are no records of analytical studies about collagenosis in Mártires de Las Tunas Provincial Pediatric Hospital; however, the number of cases admitted because of these affections has increased progressively; therefore, the risk factors with causal association of the most frequent collagenosis such as reactivated arthritis, lupus erythematosus and scleroderma were studied (AU)

Of bugs and joints: the relationship between infection and joints.

The association between microbes and joints has existed since antiquity, and remains complex. Diagnosis is often times difficult to determine despite highly suspicious clinical characteristics for the presence of an underlying infection. Over the several past decades, considerable advances have occurred in diagnostic methodologies and therapy. However, the morbidity and mortality of septic arthritis remains high. Great advances have occurred in the diagnosis, pathogenesis, and therapeutic management of reactive arthritis, and there is evidence that when the responsible microorganism is Chlamydia trachomathis, complete remission and cure is possible. Emergent infections, especially viral, has been recognized, i.e. HIV, hepatitis C, and most recently Chikengunya virus, and in the case of HIV associated articular manifestations, the introduction of HAART has resulted in a decrease in the incidence and development of newer complications such as the immune reconstitution syndrome. The infectious etiology of rheumatoid arthritis is being strongly considered once again, and the exciting association with periodontal disease is at the forefront of intense research. The gut microbiota is also being investigated and new and most interesting data is being gathered of the potential role of commensal gut organisms and the pathogenesis of rheumatoid arthritis.

Entesis, entesopatía y espondiloartritis / Entheses, enthesopathy and spondyloarthritis

Las espondiloartritis (SpA) comprenden un grupo heterogéneo de enfermedades inflamatorias articulares que comparten varias características clínicas y de laboratorio, una fuerte tendencia a la asociación familiar dada por una susceptibilidad genética relacionada con la presencia del antígeno de histocompatibilidad HLA-B27, compromiso de las entesis, afectación predominante del esqueleto axial, artritis asimétrica de grandes articulaciones en los miembros inferiores y relación con la infección como factor desencadenante de las mismas. Las SpA incluyen varios subtipos: la artropatía psoriásica (PsA), las espondiloartritis no definidas (uSpA), la artritis asociada a enfermedades inflamatorias intestinales (EII), la artritis reactiva (ReA) y la espondilitis anquilosante (EA). La característica histopatológica fundamental de las SpA es la entesitis, la cual está dada por la inflamación patológica de las entesis comprometidas, que son los sitios de inserción de los tendones, ligamentos, fascias y cápsulas articulares al hueso; así como también el sitio de unión del cartílago al hueso subcondral.

Spondyloarthritis are a heterogeneous group of inflammatory joint diseases, which share clinic and laboratory characteristics, a strong relation to hereditary factors (mainly antigen HLA-B27), enthesesitis (most commonly affecting axial skeleton), large joints asymmetric arthritis mostly in lower limbs, and its relationship with infections as a triggering factor. Spondyloarthitis include various subtypes: Psoriatic Arthropathy (PsA), Undifferentiated Spondiloarthritis (uSpA), Arthritis related to inflammatory bowel disease (IBD), Ankylosing Spondylitis (AS) and Reactive Arthritis (ReA). Fundamental histopathologic characteristic of the Spondyloarthritis is enthesitis on the sites of attachment of tendons, ligaments, joint capsules and fascias to the bone, but also over the cartilage at the subchondral bone.

Artritis reactiva secundaria a fiebre por mordedura de rata: reporte de un caso clínico / Reactive arthritis secondary to rat-bite fever: report on a clinical case

Caso clínico: Paciente de sexo masculino, de 69 años, sin otros antecedentes. Debuta con dolor en zona de la cadera derecha transitorio, evolucionando con cuadro de seis días de desarrollo de fiebre hasta 39,2ºC, calofríos, artralgias en tarso derecho, rodillas, hombros y astenia, por lo que fue hospitalizado. Al examen destacaba aumento de volumen doloroso en rodilla izquierda y hombro derecho. El estudio de líquido articular descartó artritis infecciosa y presencia de cristales intraarticulares. Los exámenes séricos mostraban parámetros inflamatorios alterados con leucocitosis, VHS y PCR elevados. Panel viral negativo. Sin otro foco inflamatorio evidente, se inició manejo antibiótico empírico con Ceftriaxona y Cloxacilina, con buena respuesta, mejorando su sintomatología y parámetros inflamatorios. Cultivos articulares negativos. El Gram de hemocultivos demostró la presencia de bacilos Gram negativos, aislando en los hemocultivos Streptobacillus moniliformis. El paciente evoluciona favorablemente, con regresión total de su cuadro articular. Discusión y conclusión: La Fiebre por Mordedura de Rata es una enfermedad sistémica que típicamente se presenta con fiebre, rash cutáneo y poliartralgias migratorias. Uno de sus principales agentes causales es el Streptobacillus moniliformis, que coloniza la nasofaringe de ratas y otros roedores. Casos aislados han sido reportados en Chile. En la Fiebre por Mordedura de Rata hasta un 50 por ciento de los pacientes desarrolla artritis con derrame articular o sin él. Puede afectar cualquier articulación, pero la más comúnmente comprometida es la rodilla. El dolor articular disminuye en las primeras tres semanas del uso de antibióticos, pero la articulación en ocasiones puede llegar a ser destruida. En sujetos sanos se han reportado tasas de mortalidad de 10 por ciento a 15 por ciento. Mientras todos los síntomas se resuelven puede haber recaídas con graves complicaciones, como meningitis, endocarditis...

Clinical case: Male patient, 69 years old and no previous record. First episode with transitory pain in the right hip zone, going on to 6 days of fever that evolves to 39.2 ºC, shivers, articular pain in the right tarsus, knees, shoulders and asthenia, so he was hospitalized. Upon examination, painful swellings of the left knee and right shoulder stood out. A study of synovial fluid ruled out infectious arthritis and presence of intra-articular crystals. Blood tests showed altered inflammatory parameters with high leukocytes, VHS and CRP. Negative viral panel. Without another evident inflammatory focus, an empirical management was initiated by means of antibiotics with Ceftriaxone y Cloxaciline, which had a good response relieving symptoms and inflammatory panels. Negative articular culturing. The blood culture Gram showed presence of negative Gram bacilli, with the isolation of Streptobacillus moniliformis in the blood cultures. Patient evolves favorably, with full regression of his articular symptoms. Discussion and conclusion: Rat-bite fever is a systemic sickness that typically presents itself with high fever, skin rash and migratory poly-articular pain. One of its main causing agents is the Streptobacillus moniliformis that colonize the nasopharynx of rats and other rodents. Isolated cases have been reported in Chile. In Rat-bite Fever up to 50 percent of patients develop arthritis with and without joint effusion. It may affect any joint, but that most commonly compromised is the knee. Articular pain subsides in the first 3 weeks of use of antibiotics, but the joint may sometimes even be destroyed. Mortality rates in healthy individuals have been reported at 10 percent to 15 percent. While all symptoms disappear there might be relapses with serious complications such as meningitis, endocarditis, myocarditis, pneumonia and fulminant sepsis that may cause the patient to die. Timely diagnose and treatment are paramount to avoid its serious...

Artritis reactiva asociada con bacteriemia por Brevundimonas diminuta / Reactive arthritis associated with Brevundimonas diminuta bacteremia

Dentro del grupo de las espondiloartritis, la artritis reactiva se define como una inflamación articular desencadenada por una infección bacteriana extra-articular. Existen pocos reportes de artritis reactiva asociada con bacteriemia simultánea causada por patógenos diversos. Brevundimonas diminuta es un bacilo Gram negativo aislado ocasionalmente de especímenes clínicos. Reportamos el caso de una paciente, sin inmunodeficiencia conocida, con artritis reactiva y bacteriemia simultánea por B. diminuta.Palabras clave: artritis reactiva, Brevundimonas diminuta, bacteriemia.

Within the group of spondyloarthritis, reactive arthritis is defined as a joint inflammation triggered by an extra-articular bacterial infection. There are few reports of reactive arthritis associated with bacteremia caused by different pathogens. Brevundimonas diminuta is a Gram-negative bacillus isolated occasionally from clinical specimens. We report a patient with reactive arthritis and concurrent B. diminuta bacteremia, without known immune deficiency.Key words: reactive arthritis, Brevundimonas diminuta, bacteremia.

Espódilo Artropatía indiferenciada, espondilitis anquilosante y artropatia psoriasica: descripcion clinica, diagnostica y radiologica / Espódilo undifferentiated arthropathy, ankylosing spondylitis and psoriatic arthropathy: clinical description, diagnostic and radiological

La espondilitis anquilosante, artritis reactiva, artritis psoriásica, artritis enteropática, espondilitis anquilosante juvenil y espondiloartropatía indife-renciada, conforman el grupo de Espóndilo artropatías seronegativas. Como síndrome clínico comparten signos y síntomas inflamatorios, compromiso articular y extra articular, HIA-B27 positivo, factor reumatoide negativo y curso crónico; debiendo ser incluidas como diagnósticos diferenciales del síndrome de dolor lumbar y cervical crónico, especialmente cuando es de tipo inflamatorio o maligno. Se realizó un estudio descriptivo, transversal y retrospectivo, elaborando una descripción clínica, diagnóstica y radiológica de pacientes incluidos en la base de datos de la unidad de reumatología de la Clínica Universitaria Bolivariana con diagnósticos de espondilitis anquilosante, espondiloanropatía indiferenciada y artritis psoriásica, atendidos entre septiembre de 2002 y julio de 2004, aplicando el formato de Espóndilo artropatías diseñado para esta investigación. Se evaluaron 27 pacientes: 55.6% hombres y 44.4% mujeres, entre 20 y 56 años. La Espóndilo artropatías serone-gativas más frecuente fue la espondilitis anquilosante (70.3%), seguida de artritis psoriásica (22.2%) y espon-diloartropatía indiferenciada (7.4%). Los síntomas más frecuentes se registraron en la región lumbar y en los talones (51.9%), rigidez artricular en la región lumbar (59.3%) y localización de la artritis en los hombros (11.1%). Los signos más frecuentes fueron Patrick y Sch6ber (62.9%).La sacroileitis bilateral y enteritis piramidal fueron los hallazgos radiológicos más frecuentes (48.1%). Para el presente estudio, la espondilítis anquilosante fue la entidad más frecuente y cursó con mayores signos y síntomas inflamatorios, predominó el compromiso del esqueleto axial, evolucionó de manera crónica y progresiva y cursó con mayor evidencia de compromiso radiológico, comparado con la anritis psoriásica y espondiloanropatía indiferenciada.
