RESUMO

La miositis aguda benigna asociada a influenza es una complicación esporádica. En Argentina, en el año 2022, hubo un aumento temprano de la circulación de influenza y del número total de las notificaciones, con la aparición de miositis secundarias. Serie clínica retrospectiva de nueve pacientes pediátricos que consultaron por dolor e impotencia funcional de extremidades inferiores, y enzimas musculares elevadas, en el hospital Pedro de Elizalde de la Ciudad Autónoma de Buenos Aires, entre agosto y octubre del 2022. En todos se detectó infección por virus influenza y se recuperaron sin secuelas. La miositis aguda benigna es una entidad infrecuente en la infancia, cuyo diagnóstico es predominantemente clínico y de recuperación ad integrum. Debe ser sospechada en pacientes con clínica compatible en contexto de alta circulación viral. La vigilancia epidemiológica aporta herramientas para identificar los virus circulantes y sus posibles complicaciones.


Benign acute myositis associated with influenza is a sporadic complication. In Argentina, in 2022, there was an early increase in influenza circulation and the total number of notifications, with the appearance of secondary myositis. Retrospective clinical series of nine pediatric patients who consulted for pain and functional impotence of the lower extremities, and elevated muscle enzymes, at the Pedro de Elizalde hospital in the Autonomous City of Buenos Aires, between August and October 2022. In all of them, infection by influenza virus and recovered without sequelae. Benign acute myositis is a rare entity in childhood, whose diagnosis is predominantly clinical and recovery ad integrum. It should be suspected in patients with compatible symptoms in a context of high viral circulation. Epidemiological surveillance provides tools to identify circulating viruses and their possible complications.

RESUMO

The first experiences with a group of drugs called immune checkpoint inhibitors for the treatment of cancer were described in 2010. They are currently used in many tumours, with successful survival outcomes but a new profile of adverse events. This new spectrum of immune-mediated toxicities includes an exaggerated inflammatory response of T lymphocyte and the development of autoimmune diseases or similar pathologies. Of these, of particular note are the rheumatological toxicities. This review aims to alert internists and rheumatologists to their recognition and clinical management.

RESUMO

En 2010 se conocieron las primeras experiencias con un grupo de medicamentos denominados inhibidores de los puntos de control inmunitario (IPCI) para el tratamiento del cáncer. Actualmente se utilizan en diferentes tumores y estadios, mejorando la sobrevida de los pacientes pero generando un nuevo perfil de toxicidad. Este nuevo espectro de toxicidades inmunomediadas (irAE) es generado por una exagerada respuesta inflamatoria de linfocitosT que puede desarrollar enfermedades autoinmunes o patologías similares. Entre ellas se hallan las toxicidades reumatológicas. Esta revisión se propone alertar a los internistas y reumatólogos a reconocer las irAE reumatológicas y conocer su manejo clínico.(AU)

RESUMO

BACKGROUND: Fibrodysplasia ossificans progressiva (FOP) is a rare autosomal dominant disease affecting connective tissue, primarily caused by de novo mutations of the ACVR1 gene. FOP is a disease with congenital malformations of the toes and heterotopic ossification in characteristic patterns that progresses with flare-ups and remissions. Cumulative damage results in disability and, eventually, death. This report aimed to describe a case of FOP to highlight the importance of early diagnosis of this rare condition. CASE REPORT: We describe the case of a 3-year-old female diagnosed with congenital hallux valgus, who initially presented with soft tissue tumors, predominantly in the neck and chest, with partial remission. Multiple diagnostic tests were performed, including biopsies and magnetic resonance imaging, with nonspecific results. We observed ossification of the biceps brachii muscle during evolution. The molecular genetic study found a heterozygous ACVR1 gene mutation that confirmed FOP. CONCLUSIONS: Knowledge of this rare disease by pediatricians is critical for an early diagnosis and for avoiding unnecessary invasive procedures that may promote disease progression. In case of clinical suspicion, performing an early molecular study is suggested to detect ACVR1 gene mutations. The treatment of FOP is symptomatic and focused on maintaining physical function and family support.


INTRODUCCIÓN: La fibrodisplasia osificante progresiva (FOP) es una enfermedad autosómica dominante rara que afecta el tejido conectivo, cuya causa principal son mutaciones de novo del gen ACVR1. Se trata de una enfermedad con malformaciones congénitas de los primeros ortejos y osificación heterotópica en patrones característicos que progresa en empujes y remisiones. El daño acumulativo provoca discapacidad y, eventualmente, la muerte. El objetivo de este trabajo fue describir un caso de FOP para favorecer el diagnóstico precoz de esta enfermedad infrecuente. CASO CLÍNICO: Se describe el caso de una paciente de 3 años, portadora de hallux valgus congénito, que inicialmente presentó tumoraciones dolorosas de tejidos blandos, de predominio en cuello y tórax, con remisión parcial de las mismas. Se realizaron múltiples pruebas diagnósticas, incluyendo biopsias e imágenes de resonancia magnética con resultados inespecíficos. En la evolución se observó osificación de músculo bíceps braquial. El estudio genético molecular encontró una mutación del gen ACVR1 en heterocigosis que confirmó el diagnóstico de FOP. CONCLUSIONES: El conocimiento de esta enfermedad por los pediatras es clave para realizar un diagnóstico precoz y evitar procedimientos invasivos innecesarios que pueden promover la progresión de la enfermedad. Ante la sospecha clínica, se sugiere realizar tempranamente el estudio molecular para detectar mutaciones del gen ACVR1. El tratamiento de la FOP es sintomático, centrado en el mantenimiento de la función física y el apoyo familiar.

RESUMO

INTRODUCTION: There is a dearth of biomarkers in Idiopathic Inflammatory Myopathies (IIM) to recognize ongoing muscle inflammation and distinguish damage from activity. Since IIM is an autoantibody-mediated disease with tertiary lymphoid organogenesis reported in the diseased muscles, we aimed to study the peripheral blood T helper (Th) subset profiling as a plausible reflection of ongoing muscle inflammation. METHODS: Fifty-six patients of IIM were compared with 21 healthy controls (HC) and 18 patients with sarcoidosis. Th1, Th17, Th17.1, and Treg cells were identified after stimulation assays (BD Biosciences). Myositis autoantibodies were tested by line immunoassay (Euroimmune, Germany). RESULTS: All Th subsets were elevated in IIM as compared with HC. As compared to HC, PM had elevated Th1 and Treg while Th17 and Th17.1 populations were higher in OM. Patients with sarcoidosis had higher Th1 and Treg but lower Th17 population as compared to IIM {Th1(69.1% vs 49.65%, p<0.0001), {Treg (12.05% vs 6.2%, p<0.0001), {Th17 (2.49% vs 4.4%, p<0.0001)}. Similar results were obtained when sarcoidosis ILD was compared with IIM ILD with a higher Th1 and Treg population but lower Th17 population in the former. No difference in T cell profile was observed after stratification for MSA positivity, type of MSA, clinical features of IIM and disease activity. CONCLUSION: Th subsets in IIM are distinct from sarcoidosis and HC with a TH17 predominant paradigm, creating a case of exploring Th17 pathway and IL-17 blockers for the treatment of IIM. However, cell profiling cannot distinguish active from inactive disease limiting its predictive potential as a biomarker of activity in IIM.

Introducción: Hay una escasez de biomarcadores en las miopatías inflamatorias idiopáticas (MII) para reconocer la inflamación muscular en curso y distinguir el daño de la actividad. Dado que la MII es una enfermedad mediada por autoanticuerpos con organogénesis linfoide terciaria informada en los músculos enfermos, nuestro objetivo fue estudiar el perfil del subconjunto de linfocitos T helpers (Th) de sangre periférica como un reflejo plausible de la inflamación muscular en curso. Métodos: Se compararon 56 pacientes de MII con 21 controles sanos (CS) y 18 pacientes con sarcoidosis. Las células Th1, Th17, Th17.1 y Treg se identificaron después de los ensayos de estimulación (BD Biosciences). Los autoanticuerpos de miositis se analizaron mediante inmunoanálisis en línea (Euroimmune, Alemania). Resultados: Todos los subconjuntos de Th estaban elevados en las MII en comparación con los CS. En comparación con los CS, PM tenía Th1 y Treg elevados, mientras que las poblaciones de Th17 y Th17.1 eran más altas en OM. Los pacientes con sarcoidosis tenían una población Th1 y Treg más alta pero una población Th17 más baja en comparación con MII {Th1 (69,1% frente a 49,65%, p<0,0001), {Treg (12,05% frente a 6,2%, p<0,0001), {Th17 (2,49% frente a 4,4%, p<0,0001)}. Se obtuvieron resultados similares cuando se comparó la EPI de sarcoidosis con la EPI de las MII con una mayor población Th1 y Treg pero menor población Th17 en la primera. No se observaron diferencias en el perfil de células T después de la estratificación por positividad de MSA, tipo de MSA, características clínicas de las MII y actividad de la enfermedad. Conclusión: Los subconjuntos de Th en las MII son distintos de la sarcoidosis y los CS con un paradigma predominante TH17, lo que crea un caso de exploración de la vía Th17 y los bloqueadores de IL-17 para el tratamiento de las MII...(AU)

RESUMO

Introducción: Las Enfermedades Pulmonares Intersticiales (EPI) afectan principalmente al intersticio pulmonar, con importante morbimortalidad asociada. Tienen un espectro de posibles etiologías que es cada vez más amplio. Hay una importante causalidad a partir de Enfermedades del Tejido Conectivo (ETC), describiéndose cada vez más casos asociados a Síndrome Antisintetasa, y con diversos patrones radiológicos según serología obtenida, agrupada en "Panel de Miositis" (PaM). El presente estudio de cohorte retrospectiva reúne PaMs realizados en el Hospital Santiago Oriente, correlacionando resultados con manifestaciones clínicas e imagenológicas. Material y Métodos: Se recuperaron 33 PaMs realizados entre 2017 y 2022, y a través de revisión de fichas de los pacientes de quienes provenían las PaMs se consignaron las principales manifestaciones clínicas, imagenológicas y de la serología reumatológica complementaria, estableciendo correlaciones entre múltiples variables. Resultados: Hubo 15 pacientes PaM positivos (45,4%), 8 de ellos (53%) ya contaban con alguna miopatía inflamatoria diagnosticada. Los principales hallazgos clínicos consignados fueron pápulas de Gottron, artritis, eritema heliotropo, Fenómeno de Raynaud y fiebre. El anticuerpo positivo más frecuente fue Ro-52. Se pudo objetivar ANA positivo en 10 casos (66,7%). Se identificó EPI en 66,7% de aquellos con PaM positivo, siendo la Neumonía Intersticial no específica fibrótica con Neumonía en Organización la manifestación más frecuente. No hubo asociación significativa entre manifestaciones imagenológicas y anticuerpos específicos. Se encontró ANA 1/80 en 66,7% de los casos, lo cual no se asoció a mayor riesgo de EPI. Conclusiones: Existe asociación entre varias ETC y las EPI. Destaca la importancia de los hallazgos clínicos para establecer un adecuado índice de sospecha, para dirigir oportunamente el estudio complementario (ej: PaM), y la eventual terapia específica.


Introduction: Interstitial Lung Diseases (ILD) mainly affect the pulmonary interstitium, with significant associated morbidity and mortality. They have a spectrum of possible etiologies that is increasingly broad. There is an important causality from Connective Tissue Diseases (CTD), describing more and more cases associated with Antisynthetase Syndrome, and with different radiological patterns according to the serology obtained, enclosed into "Panel of Myositis" (PaM). This retrospective cohort study gathers PaMs performed at Hospital Santiago Oriente, PaM results are correlated with clinical and imaging manifestations. Material and Methods: 33 PaMs performed between 2017 and 2022 were saved up and by reviewing the clinical records of the patients from whom the PaMs came, their clinical and radiological manifestations and the results of their complementary rheumatological serology were recorded to establish correlations between multiple variables. Results: There were 15 positive PaMs (45.4%), 8 (53%) of them already had some diagnosed inflammatory myopathy. The main clinical findings reported were Gottron's papules, arthritis, heliotrope erythema, Raynaud's phenomenon, and fever. The most frequent positive antibody detected was Ro-52. Positive ANA could be found in 10 cases (66.7%). PID was identified in 66.7% of those with a positive PaM, being non-specific fibrotic Interstitial Pneumonia with Organizing Pneumonia being the most frequent manifestation. There was no significant association between imaging manifestations and specific antibodies. ANA 1/80 was found in 6.7% of the cases, which was not associated with an increased risk of PID. Conclusions: There is association between several CTEs and EPIs. It is necessary to highlight the importance of the clinical findings to establish an adequate index of suspicion, in order to timely direct the complementary study (eg: PaM), and the eventual specific therapy.

RESUMO

Introducción: Las manifestaciones clínicas del síndrome de Guillain Barré y de la miositis viral aguda son diferentes. Ambos cuadros suelen ser autolimitados y pueden manifestarse tras un cuadro infeccioso. Objetivo: Informar acerca de una presentación inusual de dos afecciones en un mismo paciente. Presentación del caso: Niña de 4 años de edad, quien presenta síntomas de una miositis viral aguda, la que al mejorar, hizo más evidente la sintomatología característica del síndrome de Guillain Barré. El caso se confirmó a través de estudios hematológicos, citología de líquido cefalorraquídeo y estudios neurofisiológicos. La paciente recibió tratamiento con inmunoglobulina G humana intravenoso durante 5 días, tras lo cual presentó mejoría de los síntomas neurológicos. Conclusiones: La afectación del músculo y del sistema nervioso periférico pueden coexistir en la población pediátrica, pero no es condición usual, por lo que se necesita realizar más investigación para poder describir mejor esta entidad y su pronóstico.


Introduction: The clinical manifestations of Guillain Barré syndrome and acute viral myositis are different. Both conditions are usually self-limiting and can manifest after an infectious process. Objective: To report an unusual presentation of two conditions in the same patient. Case presentation: A 4-year-old girl presented with symptoms of acute viral myositis, which, with improvement, made more evident the characteristic symptoms of Guillain Barré syndrome. The case was confirmed through hematological studies, cerebrospinal fluid cytology and neurophysiological studies. The patient was treated with intravenous human immunoglobulin G for 5 days, after which she showed improvement of the neurological symptoms. Conclusions: The involvement of the muscle and the peripheral nervous system may coexist in the pediatric population, but it is not a usual condition, so more research is needed to better describe this entity and its prognosis.

RESUMO

A case report is presented of a 50-year-old woman who was seen in Accident and Emergency because of pain in the lumbar area. She was subsequently diagnosed with septic arthritis of the left hip due to being Neisseria gonorrhoeae positive for beta-lactamase. She responded to treatment with ceftriaxone, but later required a total hip replacement.


Presentamos el caso de una mujer de 50 arios, sin antecedentes de importancia, a quien se le diagnosticó inicialmente lumbago e infección de vías urinarias. Por persistencia del dolor y limitación de la movilidad en la cadera izquierda se inicia el estudio de artritis séptica, que fue provocada por Neisseria gonorrhoeae betalactamasa positiva, sensible a tratamiento con ceftriaxona, con posterior deterioro articular, el cual requirió reemplazo total de cadera.

RESUMO

Introducción: la miositis aguda benigna de la infancia (MAB) es una enfermedad benigna y autolimitada, considerada en la actualidad como una secuela de enfermedades víricas. Su manifestación clínica típica son las mialgias en las extremidades inferiores acompañadas de rechazo a caminar. Pacientes y métodos: realizamos una revisión retrospectiva de los casos de MAB atendidos en nuestro servicio de urgencias pediátricas durante un periodo de 25 años. Obtuvimos datos demográficos, clínicos y de laboratorio a través de la revisión sistemática de historias clínicas. Se elaboraron estadísticas descriptivas y se efectuaron comparaciones entre grupos a través del test U de Mann-Whitney. Las correlaciones entre variables cuantitativas se realizaron mediante el análisis de rangos de Spearman. Resultados: se identificaron 139 casos de MAB (74,8% varones). La mayor incidencia se produjo en los meses de invierno y en niños de 4-8 años. Las mialgias bilaterales en miembros inferiores fueron el principal motivo de consulta. El 86,3% referían fiebre acompañada de síntomas respiratorios (88,5%), confirmándose en urgencias la infección por virus influenza en 37 casos (75,6% del serotipo B). En el momento del diagnóstico, la mediana de creatincinasa (CK) fue 1794 U/l, no existiendo diferencias significativas en función del sexo (p = 0,687). La función renal fue normal en todos los pacientes, ninguno necesitó hospitalización. Conclusiones: la MAB es una entidad fácilmente reconocible teniendo en cuenta sus manifestaciones clínicas y analíticas. A pesar de las masivas elevaciones de CK, sus complicaciones son excepcionales y la mayoría de los pacientes pueden ser dados de alta con tratamiento conservador (AU)


Introduction: benign acute childhood myositis (BACM) is a benign, self-limiting disease currently believed to be a sequela of viral infections. The typical clinical presentation is myalgia in the lower extremities accompanied by refusal to walk.Patients and methods: we did a retrospective review of all the cases of BACM managed in our paediatric emergency department over a 25-year period. We collected data on demographic, clinical and laboratory variables through the systematic review of health records. We performed a descriptive statistical analysis, followed by comparison of groups with the Mann-Whitney U test. The correlation between quantitative variables was assessed by means of the Spearman rank coefficient.Results: we identified 139 cases of BACM (74.8% in male patients). The highest incidence corresponded to children aged 4 to 8 years and the winter months. Bilateral lower limb myalgia was the most frequent presenting complaint. Fever was reported in 86.3% of cases, accompanied by respiratory symptoms (88.5%); influenza virus infection was confirmed in 37 cases (75.6% serotype B). At diagnosis, the median creatine kinase (CK) level was 1794 U/l, with no significant differences between the sexes (p=0.687). All patients had normal renal function, and none required hospitalization.Conclusions: based on its clinical and analytical manifestations, BACM is easy to recognise. Although massive elevation of CK is common, complications are rare, and most patients can be discharged with conservative treatment. (AU)

RESUMO

Se describe el caso de una paciente de 9 años que presenta, durante el seguimiento por infección por SARS-CoV-2, incapacidad para la deambulación por dolor de extremidades inferiores. Ante una clínica y exploración compatible con miositis, se realiza analítica sanguínea en la que se observa una elevación de creatinfosfoquinasa (CPK). La paciente presenta buena evolución con tratamiento sintomático. A propósito del caso se realiza una revisión bibliográfica de los casos pediátricos de miositis asociados a la infección por SARS-CoV-2 (AU)


We describe the case of a 9-year-old patient who presented with inability to walk due to lower extremity pain in the follow-up of infection by SARS-CoV-2. Since the manifestations and findings of the examination were compatible with myositis, a blood test was performed that evinced elevation of creatine phosphokinase. The patient had a favourable outcome with symptomatic treatment. In the context of this case, we conducted a literature review of paediatric cases of myositis associated with SARS-CoV-2 infection.

RESUMO

BACKGROUND AND OBJECTIVES: ILD patients can be positive to highly specific autoantibodies of connective tissue diseases (CTD). Among them stand out myositis-specific and associated autoantibodies (MSA/MAA). There is limited knowledge about treatment response and prognosis of ILD patients positive to MSA/MAA (MSA/MAA-ILD). Our aim was to describe clinical, radiological and pulmonary function (PF) of MSA/MAA-ILD Latin-American patients and risk factors associated to PF at onset and long term follow up. METHODS: Multicentric retrospective study of MSA/MAA-ILD patients evaluated between 2016 and 2018 in 3 ILD clinics in Latin America. Clinical, functional and tomographic variables were described. Variables associated with poor baseline PF and associated with functional improvement (FI) were analyzed in a multivariate logistic regression model. RESULTS: We included 211 patients, 77.4% female, mean age 57 years old. Most frequent MSA/MAA were Ro-52 and Jo-1. Poor baseline PF was associated to ILD as initial diagnosis and NSIP/OP HRCT pattern. 121 patients were included in the follow up PF analysis: 48.8% remained stable and 33% had a significant FI. In multivariate analysis, OP pattern on HRCT was associated with FI. Systemic symptoms from the beginning and the absence of sclerodactyly showed a trend to be associated with FI. CONCLUSIONS: Worse baseline PF could be related to the absence of extra-thoracic symptoms and "classic" antibodies in CTD (ANA), which causes delay in diagnosis and treatment. In contrast, FI could be related to the presence of extra-thoracic signs that allow timely diagnosis and therapy, and more acute and subacute forms of ILD, such as OP pattern.

RESUMO

Objetivos: Describir la metodología del Registro de pacientes con miopatía inflamatoria idiopática (MII) de España (Myo-Spain), así como sus fortalezas y limitaciones. El objetivo principal del proyecto es analizar la evolución y el manejo clínico de una cohorte de pacientes con MII. Material y método: Estudio observacional, longitudinal, ambispectivo y multicéntrico de una cohorte de pacientes con MII atendidos en servicios de reumatología de España. Se incluirán todos los pacientes con diagnóstico de MII en seguimiento habitual por los centros participantes, sin tener en cuenta la edad de inicio del proceso. Los casos incidentes serán todos los pacientes que al inicio del estudio en cada centrosu estén diagnosticados desde hace menos de 12 meses y casos prevalentes desde hace más de 12 meses. Se construirá un registro en el que se incluirán los datos de la visita basal, del año y dos años. Se recogerán variables sociodemográficas, clínicas, analíticas, complicaciones, comorbilidad, asociación con otras enfermedades reumáticas, ingresos hospitalarios, mortalidad y tratamientos. Además, se determinarán índices, escalas y cuestionarios de actividad, afectación muscular, daño, discapacidad y calidad de vida. El periodo de reclutamiento será de 23 meses. El propósito es conseguir una cohorte de 400 pacientes con MII. Conclusion: esEl estudio Myo-Spain constituye la oportunidad para desarrollar una cohorte de pacientes incidentes y prevalentes con MII en España. Myo-Spain permitirá evaluar en detalle, las características clínicas de la enfermedad en diferentes momentos. Se espera que la información exhaustiva recogida en las visitas suponga una amplia fuente de datos para futuros análisis.(AU)


Objectives: To describe the methods of the Spanish Registry of patients with idiopathic inflammatory myopathy (IIM) (Myo-Spain), as well as its strengths and limitations. The main objective of the project is to analyse the evolution and clinical management of a cohort of patients with IIM. Methods: Observational, longitudinal, ambispective and multicentre study of a cohort of patients with IIM seen in rheumatology units in Spain. All patients with a diagnosis of IMM will be included in the regular follow-up of the participating centres, regardless of age on initiation of the process. Incident cases will be all patients who at the beginning of the study have been diagnosed for less than 12 months and prevalent cases for more than 12 months. The registry will include data from the visit at baseline, one year and two years. Socio-demographic, clinical, analytical variables, complications, comorbidities, association with other rheumatic diseases, hospital admissions, mortality and treatments will be collected. In addition, indices, scales and questionnaires of activity, muscle involvement, damage, disability, and quality of life will be determined. The recruitment period will be 23 months. The purpose is to obtain a cohort of 400 patients with IMM. Conclusions: Myo-Spain registry provides the opportunity to develop a cohort of incident and prevalent patients with IMM in Spain. Myo-Spain will be able to assess in detail the clinical characteristics of the disease at different times. The comprehensive information collected during the visits is expected to provide a broad source of data for future analysis.(AU)

Antecedentes y objetivos: Los pacientes con enfermedad pulmonar intersticial (EPI) pueden presentar positividad para autoanticuerpos específicos de enfermedades autoinmunes, como los anticuerpos mioespecíficos (AME) o mioasociados (AMA). Existe escasa información disponible sobre pronóstico y respuesta al tratamiento de estos pacientes. Nuestro objetivo fue describir las características clínicas, radiológicas, funcionales y pronósticas de una cohorte latinoamericana de pacientes con EPI y AME/AMA. Métodos: Estudio retrospectivo multicéntrico de una cohorte pacientes con EPI y AME/AMA, evaluados en tres centros latinoamericanos entre 2016 y 2018. Describimos variables clínicas, tomográficas y funcionales. Analizamos variables asociadas con valores funcionales bajos al inicio y mejoría funcional mediante regresión logística. Resultados: Incluimos 211 pacientes, 77,4% mujeres, con una media de edad de 57 años. Los anticuerpos más frecuentes fueron Ro-52 y Jo-1. Valores funcionales bajos al inicio se asociaron con la presencia de EPI desde el debut y con un patrón de neumonía intersticial no específica (NINE)/neumonía organizativa (NO) en la tomografía computarizada de alta resolución (TACAR). Se analizó la evolución funcional en 121 pacientes: 48% permanecieron estables y 33% presentaron mejoría. El patrón de NO en TACAR, se asoció significativamente con mejoría funcional, mientras que la presencia de EPI desde el debut y la ausencia de esclerodactilia mostraron una tendencia en el análisis multivariado. Conclusiones: Valores funcionales bajos al debut podrían asociarse con la ausencia de síntomas extratorácicos al inicio, por llevar a un diagnóstico y tratamiento tardíos. Por el contrario, la presencia de síntomas sistémicos al debut, junto con formas más agudas de EPI como NINE/NO podrían asociarse con mejoría funcional por permitir un diagnóstico y tratamiento precoz.(AU)

RESUMO

La miositis de origen vírico o bacteriano es frecuente en la edad pediátrica. Causa dolor muscular y debilidad, con fiebre y malestar general. Una causa es la infección por Bartonella henselae, bacteria implicada en la enfermedad por arañazo de gato que, a veces, causa afectación multisistémica. Se presenta el caso de una adolescente que acudió al servicio de urgencias por mialgia intensa, malestar, adelgazamiento y esplenomegalia. En el labortorio se observaron parámetros inflamatorios elevados. Refería contacto con un gato. Entre los estudios realizados, la resonancia magnética (RM) de miembros inferiores mostró una imagen compatible con miositis inflamatoria bilateral. En la RM abdominal, se observaron tres lesiones esplénicas no detectadas previamente y el fondo de ojo mostraba una lesión compatible con oclusión arterial retiniana o vasculitis. Se indicó tratamiento antibiótico por vía intravenosa durante 21 días con cefotaxima y cloxacilina, tras los cuales desaparecieron los signos y síntomas, aunque los reactantes inflamatorios persistieron elevados. Con base en el cuadro clínico (miositis + coriorretinitis + absceso esplénico) se pensó en una posible infección por B. henselae y se inició tratamiento oral con azitromicina y rifampicina durante 14 días. Luego del tratamiento, los valores de laboratorio fueron normales, así como la RM de control, y se constató una IgG positiva para la bacteria


Infectious myositis, whether viral or bacterial, is frequent in pediatric age. It causes muscle pain and weakness, associated with fever and general malaise. One cause is Bartonella henselae, responsible for cat scratch disease, which sometimes causes systemic symptoms. We report the case of an adolescent who came to the emergency room with intense myalgia, malaise, weight loss and splenomegaly. Blood tests showed high inflammatory markers. She had been in touch with a cat. Studies were carried out including: lower limbs MRI suggestive of bilateral inflammatory myositis, abdominal MRI with three previously undetected splenic lesions and dilated fundus examination that showed possible retinal arterial occlusion or vasculitis. After 21 days of intravenous antibiotic therapy (cefotaxime + cloxaciline), she became asymptomatic, but inflammatory markers remained high. Suspecting Bartonella henselaeinfection (myositis + chorioretinitis + splenic abscess), oral azithromycin and rifampicin were prescribed for 14 days. Blood tests and control MRI became normal, and IgG was positive.

RESUMO

INTRODUCTION: Despite the current trend toward less aggressive therapeutic approaches, acute haematogenous osteomyelitis (AHO) continues to be a challenge and is associated with significant morbidity worldwide. Our aim was to assess whether compliance with the current protocol was achieved in 80% of cases, to identify complications and the associated risk factors, and to analyse trends in the aetiology and management of AHO in the paediatric population. METHODS: We conducted a longitudinal, observational, single-centre study in patients with AHO aged less than 18 years admitted to a paediatric hospital between 2008 and 2018 divided in 2 cohorts (before and after 2014). We analysed data concerning demographic and clinical characteristics and outcomes. RESULTS: The study included 71 children with AHO, 56% male, with a median age of 3 years (interquartile range, 1-11). We found a 1.8-fold increase of cases in the last 5 years. The causative agent was identified in 37% of cases: MSSA (54%), MRSA (4%), S. pyogenes (19%), K. kingae (12%), S. pneumoniae (8%), and N. meningitidis (4%). Complications were identified in 45% of patients and sequelae in 3.6%. In recent years, there was an increase in myositis (30% vs 7%; P=.02), septic arthritis (68 vs 37.2%; p=0.012) and in the proportion of patients treated for less than 4 weeks (37 vs 3.5%; p=0.012), with a similar sequelae rates. The risk factors associated with complications were age 3 or more years, C-reactive protein levels of 20mg/L or higher, time elapsed between onset and admission of 5 or more days and positive culture, although the only factor that continued to be significantly associated in the multivariate analysis was positive culture. The presence of complications was a risk factor for sequelae at 6 months. CONCLUSIONS: Our study confirms that AHO can be aggressive. The identification of risk factors for complications is essential for management.
