Objective: To investigate the clinical characteristics of systemic juvenile idiopathic arthritis combined with coronary artery dilatation. Methods: A retrospective analysis was performed on the clinical data, including clinical manifestations, blood routine, inflammatory factors, echocardiography, vascular ultrasound and CT angiography, treatment and outcomes, etc, of 5 cases with systemic juvenile idiopathic arthritis combined with coronary artery dilation admitted to Department of Rheumatology in the affiliated Children's Hospital of Capital Institute of Pediatrics from May 2019 to June 2021. Results: There were 2 males and 3 females among 5 cases. The onset age ranged from 7 months to 4 years 7 months.The diagnostic time ranged from 1.5 months to 3.0 months.Four cases were diagnosed as atypical Kawasaki disease. Three cases showed unilateral coronary artery dilation.Two cases showed bilateral coronary artery dilation.Four cases developed multiple organ injuries.Three cases developed macrophage activation syndrome.Three cases developed lung injury.Two cases developed pericardial effusion.One case developed pulmonary hypertension.As for treatment, 3 cases treated with methylprednisolone pulse therapy and methotrexate combined with cyclosporine, improved after the final application of biological agents, and have stopped prednisone. The other 2 cases were treated with adequate oral prednisone and gradually reduced, and methotrexate was added at the same time, 1 case relapsed in the process of reduction. No other vascular involvement was found in 5 cases. Coronary artery dilation recovered completely after 1 to 3 months of treatment. Conclusions: Systemic juvenile idiopathic arthritis combined with coronary artery dilatation has the clinical characteristics of small onset age, long diagnostic time, prone to multiple organ injuries. Corticosteroids and conventional immunosuppressive agents are not sensitive, and biological agents should be used as soon as possible.The prognosis of coronary artery dilation is good after timely treatment.

Objective: To investigate the efficacy and safety of infliximab (IFX) therapy for children with Kawasaki disease. Methods: Sixty-eight children with Kawasaki disease who received IFX therapy in Children's Hospital of Fudan University from January 2014 to April 2021 were enrolled. The indications for IFX administration, changes in laboratory parameters before and after IFX administration, response rate, drug adverse events and complications and outcomes of coronary artery aneurysms (CAA) were retrospectively analyzed. Comparisons between groups were performed with unpaired Student t test or Mann-Whitney U test or chi-square test. Results: Among 68 children with Kawasaki disease, 52 (76%) were males and 16 (24%) were females. The age of onset was 2.1 (0.5, 3.8) years. IFX was administered to: (1) 35 children (51%) with persistent fever who did not respond to intravenous immunoglobulin (IVIG) or steroids, 28 of the 35 children (80%) developed CAA before IFX therapy; (2) 32 children (47%) with continuous progression of CAA; (3) 1 child with persistent arthritis. In all cases, IFX was administered as an additional treatment (the time from the onset of illness to IFX therapy was 21 (15, 30) days) which consisted of second line therapy in 20 (29%), third line therapy in 20 (29%), and fourth (or more) line therapy in 28 (41%). C-reactive protein (8 (4, 15) vs. 16 (8, 43) mg/L, Z=-3.38, P=0.001), serum amyloid protein A (17 (10, 42) vs. 88 (11, 327) mg/L, Z=-2.36, P=0.018) and the percentage of neutrophils (0.39±0.20 vs. 0.49±0.21, t=2.63, P=0.010) decreased significantly after IFX administration. Fourteen children (21%) did not respond to IFX and received additional therapies mainly including steroids and cyclophosphamide. There was no significant difference in gender, age at IFX administration, time from the onset of illness to IFX administration, the maximum coronary Z value before IFX administration, and the incidence of systemic aneurysms between IFX-sensitive group and IFX-resistant group (all P>0.05). Infections occurred in 11 cases (16%) after IFX administration, including respiratory tract, digestive tract, urinary tract, skin and oral infections. One case had Calmette-Guérin bacillus-related adverse reactions 2 months after IFX administration. All of these adverse events were cured successfully. One child died of CAA rupture, 6 children were lost to follow up, the remaining 61 children were followed up for 6 (4, 15) months. No CAA occurred in 7 children before and after IFX treatment, while CAA occurred in 54 children before IFX treatment. CAA regressed in 23 (43%) children at the last follow-up, and the diameter of coronary artery recovered to normal in 10 children. Conclusion: IFX is an effective and safe therapeutic choice for children with Kawasaki disease who are refractory to IVIG or steroids therapy or with continuous progression of CAA.

Abstract A 32-year-old man diagnosed with Kawasaki disease at the age of three years presented with coronary artery aneurysm (CAA). The aneurysm increased in size, and the patient was referred to our hospital for surgery. Preoperative computed tomography scan showed a super-giant right CAA and giant left CAAs; surgery was performed. The super-giant right CAA was resected, and the ostium of the right coronary artery was closed; then, coronary artery bypass grafting was performed. The left CAAs were not treated surgically because the risk of rupture was low. Here, we describe the successful surgical treatment of a right super-giant CAA.

Kawasaki disease (KD) can be a primary cause of an acute coronary syndrome in young adults, with or without a history of KD during childhood. We report a 31year old female, admitted for acute chest pain. She had negative T waves on DIII and AVF leads of the electrocardiogram. Troponins were positive. A cardiac magnetic resonance was compatible with an acute inferior myocardial infarction. In the coronary angiography she had a calcified complete occlusion of the proximal right coronary artery. The left coronary artery had no visible lesions. A computed angiogram showed an extensive calcified and thrombotic aneurysm of the right coronary artery, compatible with Kawasaki disease (KD). The patient was discharged seven days after admission in good conditions.

Se caracteriza por presentar compromiso multiorgánico con parámetros inflamatorios elevados y manifestaciones clínicas graves, siendo el corazón el órgano más severamente comprometido. OBJETIVO: Describir las características clínicas y de laboratorio de 23 pacientes con diagnóstico de PIMS con compromiso cardiovascular hospitalizados en un centro único. MÉTODO: Se efectuó un estudio retrospectivo analizando los hallazgos clínicos y de laboratorio junto a las manifestaciones cardiovasculares que presentaron estos pacientes. RESULTADOS: 23/29 pacientes con PIMS (78%) presentaron manifestaciones digestivas y mucocutáneas. Las manifestaciones cardiovasculares fueron: Síndrome Kawasaki y "Kawasaki like" sin compromiso coronario en 15/23 (65%) y con compromiso coronario en 3 (13%). Shock en 9 pacientes (39%), injuria miocárdica- miocarditis en 8 (35%) y derrame pericárdico en 13 (56%). Trastornos del ritmo cardíaco se observaron en 6 pacientes (26%). La terapia más utilizada fue inmunoglobulina y corticoides. 18 /23 requirieron manejo en unidades de intermedio y/o intensivo. Un 70% de los pacientes se recuperó del compromiso cardiovascular antes del alta. CONCLUSIÓN: El compromiso cardiovascular en PIMS es la complicación más frecuente de esta enfermedad, que se acompaña de manifestaciones inmunológicas y hematológicas graves lo que hace necesario un tratamiento multidisciplinario para un mejor manejo de estos pacientes.

INTRODUCTION: Pediatric Multisystemic Inflammatory Syndrome (PIMS) has emerged as a new disease in children, secondary to SARSCoV-2 infection. It is characterized by multi-organ involvement with elevated inflammatory parameters and severe clinical manifestations, the heart being the organ most severely involved. OBJETIVE: to describe the clinical and laboratory characteristics of 23 patients diagnosed with PIMS with cardiovascular involvement hospitalized in a single center. METHOD: We conducted a retrospective study in which we analyzed the clinical and laboratory findings along with the cardiovascular manifestations presented by these patients. Results: 23/29 patients with PIMS and cardiovascular involvement were selected, 78% had digestive and mucocutaneous manifestations. Cardiovascular manifestations consisted of KawasakiKawasaki like syndrome without coronary involvement in 15/23 (65%) and coronary involvement in 3 (13%). Nine patients developed shock (39%), 8 (35%) myocardial injury in and 13 (56%) pericardial effusion.. Heart rhythm disorders were observed in 6 patients (26%). The main therapy was immunoglobulin and corticosteroids. 18 /23 required management in intermediate and/or intensive care unit. 70% of patients recovered from cardiovascular involvement before discharge. CONCLUSION: Cardiovascular involvement in PIMS is the most frequent complication of this disease, but it is associated with severe immunological and hematological manifestations, which makes necessary a multidisciplinary treatment for a better management

Abstract We report a case of a 23-year-old man who was diagnosed with Kawasaki disease that progressed to a coronary aneurysm in the left main coronary artery (LMA). He had suffered from acute coronary syndrome and then underwent an emergent percutaneous coronary angioplasty, in which a polyurethane-covered stent was placed inside the aneurysm. The stent was thrombosed one year later, despite the patient had been treated with anticoagulant and antiplatelet therapy. Emergency percutaneous intervention was then performed. LMA was reopened and stent malposition was observed. Therefore, urgent coronary bypass grafting was performed in which a high degree of competitive flow was observed through the reopened stent. LMA was ligated at the inflow of the aneurysm, resulting in an improvement of graft flow. Left main ligature has not been previously reported.

Resumen Objetivo: Describir las manifestaciones cardiacas en la etapa aguda de la enfermedad de Kawasaki en pacientes atendidos en un hospital de tercer nivel de la Ciudad de México, México. Métodos: Estudio retrospectivo, descriptivo en pacientes con diagnóstico de enfermedad de Kawasaki de agosto de 1995 a diciembre del 2016 en el Instituto Nacional de Pediatría, México. Se estudio la demografía de los pacientes, características clínicas, tratamiento empleado y desarrollo de complicaciones cardiacas en la etapa aguda de la enfermedad. Resultados: Se estudiaron 508 casos de enfermedad de Kawasaki. La edad media al diagnóstico fue de 37.64 ± 35.56 meses. Predominio de pacientes masculinos del 65.4%, con una relación masculino/femenino de 1.88:1. La mayoría de los casos (79.2%) tuvo una presentación completa. La gammaglobulina intravenosa fue administrada en 92.4% de los casos. Veintiocho pacientes (5.5%) desarrollaron arritmias, se presentaron cambios en el segmento ST en 29 pacientes (5.6%) y 5 pacientes desarrollaron isquemia miocárdica. En el ecocardiograma inicial, 51 pacientes (9.9%) presentaron datos de miocarditis, 72 pacien- tes (14%) datos de pericarditis y 77 casos tuvieron derrame pericárdico (15%). Se detectaron alteraciones en las arterias coronarias en 169 casos (32.9%). Cuatro pacientes fallecieron en la etapa aguda de la enfermedad por complicaciones cardiacas de la enfermedad de Kawasaki. Conclusiones: En México cada vez existen más casos de enfermedad de Kawasaki con un alto porcentaje de manifestaciones cardiacas al diagnóstico. Se requiere de un mayor conocimiento de la enfermedad en México, para poder establecer cuál es la evolución cardiológica de los pacientes en el país.

Abstract Objectives: To describe the cardiac manifestations in the acute phase of patients with Kawasaki disease treated in a third level Children's hospital in Mexico City, Mexico. Methods: A cross-sectional study was conducted in patients with a diagnosis of Kawasaki disease treated in this hospital from August 1995 to December 2016. Information included patient demographics, clinical features, treatment used, electrocardiographic findings, extra-coronary echocardiographic findings, and the development of coronary artery aneurysms in the acute phase of the disease. Results: The study included 508 cases of Kawasaki disease, with a mean age at diagnosis of 37.64 ± 35.56 months (range from 2 to 200 months). Almost two-thirds (65.4%) of the patients were male, with a male/female ratio of 1.88:1. Complete Kawasaki disease was diagnosed in 79.2% of cases. Almost all cases (92.4%) received intravenous immunoglobulin. Twenty-eight patients (5.5%) developed arrhythmias, ST changes developed in 29 patients (5.6%), and 5 patients presented with ischaemic changes. In the initial echocardiographic evaluation, 51 patients (9.9%) were diagnosed with myocar- ditis, 72 patients (14.0%) with pericarditis and 77 cases (15.0%) developed pericardial effusion. Coronary artery anomalies were detected in 169 cases (32.9%). 32 cases were diagnosed as giant coronary aneurysms. Four patients died from cardiac complications in the acute phase of the disease. Conclusions: There has been an increase in the diagnosis of Kawasaki disease in Mexico. They presented with more cardiac complications than reported in literature. An increased knowledge of Kawasaki disease is required in Mexico in order to establish the cardiac outcomes of this group of patients.

Introduction Chronic otomastoiditis causes pain, otorrhea, and hearing loss resulting from the growth of tissue within the normally hollow mastoid cavity. Objectives In this report, we used a lipidomics approach to profile major mastoid bone and tissue lipids from patients with and without otomastoiditis. Methods The bone dust created during mastoidectomy, as well as the mastoid tissue, was analyzed from seven patients. Bone dust was also collected and analyzed in an additional four otologic cases (parotidectomy requiring mastoidectomy). Samples were subjected to a modified Bligh/Dyer lipid extraction, then high-performance thin-layer chromatography (HPTLC), combined gas chromatography/electron impact-mass spectrometry (GC/EI-MS), and flow-injection/electrospray ionization-tandem mass spectrometry (FI/ESI-MSMS). Data were analyzed for identification and profiling of major lipid components. Results HPTLC revealed the presence of various lipid classes, including phosphatidylcholines, cholesterol, and triacylglycerols. GC/EI-MS analysis revealed the presence of cholesterol and several fatty acids. FI/ESI-MSMS analysis revealed a host of phosphatidylcholines, phosphatidylethanolamines, and cholesteryl esters. Conclusion We used a lipidomics approach to develop an efficient (both in time and tissue amount) methodology for analysis of these tissues, identify the most abundant and common lipid species, and create a base of knowledge from which more focused endeavors in biomarker discovery can emerge. In an effort toward improved patient categorization and individualized intervention, the ultimate goal of this work is to correlate these lipid molecules to disease state and progression. This is the first reported study of its kind on these tissues. .

El pseudo-aneurisma de arteria coronaria es extremadamente raro. Su historia natural es poco conocida y su tratamiento discutido. Se presenta el caso de un paciente con pseudo-aneurisma de tronco de la coronaria izquierda e infarto antero-apical del ventrículo izquierdo cinco años después de un paro cardíaco secundario a un traumatismo no penetrante de tórax. Se consideró entonces que la lesión no era pasible de corrección percutánea o quirúrgica por lo que se optó por tratamiento médico conservador. Una angiografía coronaria por tomografía computarizada multicorte realizada 10 años después del evento inicial mostró ausencia de progresión de la lesión.

Coronary pseudo-aneurysm is an extremely rare entity. Its natural history is scarcely known and its treatment is controversial. We report a case of pseudo-aneurysm of the left main coronary artery associated with an antero-apical infarct of the left ventricle diagnosed five years after a cardiac arrest following a non-penetrating thoracic trauma. The patient was treated conservatively because percutaneous or surgical correction were not considered suitable for this lesion. A multidetector computed tomography coronary angiogram performed 10 years after the initial event showed no evidence of progression.

OBJETIVO: Chamar a atenção para as complicações, que podem surgir em qualquer fase da Doença de Kawasaki (DK), para os fatores de risco que contribuem para o aparecimento dessas complicações e para as possíveis sequelas da doença, sejam elas transitórias ou permanentes. MÉTODOS: Estudo prospectivo (coorte clínica) realizado entre abril de 2002 e abril de 2009 de 115 pacientes com DK internados no serviço de Reumatologia Pediátrica do Hospital Geral do Distrito Federal. Todos os pacientes foram sequencialmente avaliados com exames clínicos e laboratoriais, ecocardiogramas com Doppler, imitanciometria, potenciais evocados auditivos, avaliação psicológica, exame oftalmológico e, em um paciente com coreia, angiorressonância magnética cerebral. Em todos os pacientes foram aplicados questionários avaliando a possível presença de dificuldades cognitivas, emocionais, comportamentais e sociais. RESULTADOS: Vinte e cinco pacientes (21,7 por cento) apresentaram aneurismas de coronárias. Trinta e oito pacientes (33 por cento) apresentaram perda auditiva neurossensorial durante a doença aguda e subaguda, e 13 pacientes (11,3 por cento) mantiveram a perda auditiva seis meses após a primeira avaliação. Outras complicações observadas foram: paralisia facial em um paciente (0,9 por cento), ataxia na fase aguda e subaguda em 11 pacientes (9,5 por cento), complicações oftalmológicas em 15 pacientes (13,2 por cento), constatando-se uveíte em 13, edema de papila em um paciente e hemorragia conjuntival em outro. Um paciente apresentou coreia (0,9 por cento) sendo que a angioressonância magnética evidenciou alterações compatíveis com isquemia cerebral. Em um paciente constatou-se a presença de aneurisma de aorta torácica (0,9 por cento), e outro apresentou vasculite necrosante que evoluiu com gangrena periférica e perda da ponta da língua (0,9 por cento). Alterações de comportamento durante a convalescença (20 por cento) foi observada em 23 crianças. CONCLUSÃO: A DK pode evoluir com complicações diversas, mesmo meses após a fase aguda da doença, eventualmente resultando em sequelas permanentes. Quanto mais precoce forem o diagnóstico e a intervenção terapêutica com a administração de IgG IV, menor será a ocorrência de complicações. Presença de trombocitose, anemia e de atividade inflamatória elevada e por tempo prolongado são fatores de risco para o aparecimento de complicações.

OBJECTIVE: To draw attention to complications that might arise in any Kawasaki disease (KD) stage, risk factors contributing to the onset of complications and possible transient or permanent disease sequelae. METHODS: Prospective study (clinical cohort) conducted between April 2002 and April 2009 of 115 patients with KD admitted to the Pediatric Rheumatology Clinic of the General Hospital of the Federal District, Brazil. All patients were sequentially assessed with clinical and laboratory examinations, Doppler echocardiography, imitanciometry, auditory evoked potentials, psychological evaluation, ophthalmologic examination and, in one patient with chorea, cerebral magnetic resonance angiography. In all patients, a questionnaire assessing the possible presence of cognitive, emotional, behavioral and social disorders was applied. RESULTS: Twenty-five patients (21.7 percent) had coronary aneurisms. Thirty eight patients (33 percent) had a sensorineural auditory loss during the acute and subacute phases of the disease and 13 patients (11.3 percent) maintained the auditory loss six months after the first assessment. Other complications observed were as follows: facial palsy in one patient (0.9 percent), ataxia in acute and subacute phases in 11 (9.5 percent); 15 patients had ophthalmologic complications (13.2 percent), with uveitis in 13, papilledema in one patient, and conjunctival hemorrhage in another patient. One patient experienced chorea (0.9 percent), with a magnetic resonance angiography showing changes consistent with cerebral ischemia. In one patient, a thoracic aorta aneurism was found (0.9 percent) and another patient had a necrotizing vasculitis progressing to peripheral gangrene and tongue tip loss (0.9 percent). Behavioral changes over convalescence were observed in 23 children. CONCLUSION: KD may progress with several complications even within months of the disease acute phase, eventually resulting in permanent sequelae. The earlier the diagnosis and therapeutic intervention with IV IgG administration are, the lower will be the occurrence of complications; the presence of thrombocytosis, anemia and elevated and extended inflammatory activity are risk factors for complication arising.

El desarrollo de aneurismas en el tronco coronario izquierdo es una patología rara con una incidencia de 0,1% y cuya etiología puede ser congénita o adquirida. La importancia clínica de los aneurismas coronarios estriba en el riesgo de ruptura coronaria espontánea y de infarto de miocardio por trombosis, embolismo o espasmo. Este reporte describe el caso de un paciente de 26 años de edad, estudiante de licenciatura en educación física, con un aneurisma gigante sacular del tronco coronario izquierdo asociado con estenosis suboclusiva posaneurismática que condicionó la presencia de manifestaciones de isquemia miocárdica de alto riesgo. Presentamos la imaginología y una revisión sobre la etiología, los aspectos clínicos, diagnósticos y terapéuticos de los aneurismas del tronco coronario izquierdo.

The development of the left main coronary artery aneurysms is a rare pathologic process with an incidence of 0.1% and whose etiology can be either congenital or acquired. The clinical importance of the aneurysms of the left main coronary artery is based in the potential risk of spontaneous dissection and rupture and myocardial infarction for thrombosis, embolism or spasm. We report the case of a 26-year-old athlete with agiant aneurysm of the left main coronary artery associated with suboclusive stenosis and clinical manifestations of myocardiali schemia. We present the imagenological characteristics and bibliographic review about the clinical, diagnostic and therapeutic aspects of the left main coronary artery aneurysm.

A dissecção de aorta pode ocorrer tardiamente após cirurgia de troca de valva aórtica e raramente no primeiro mês pós-operatório. A dissecção de artéria coronariana é rara e normalmente ocorre depois de angiografia coronariana. Relata-se um caso raro de dissecção de artéria coronária, seguido de infarto do miocárdio, no pós-operatório imediato de troca de valva aórtica com correção e evolução bem-sucedidas.

Late aortic dissection can occur after aortic valve replacement surgery, but rarely in the first postoperative month. Coronary artery dissection is rare and usually occurs after coronary angiography. We report a rare case of coronary artery dissection followed by myocardial infarction in the immediate postoperative period of a successful aortic valve replacement with a good postoperative evolution.

A dissecção coronária iatrogênica apresenta alta morbidade e mortalidade. Diante da oclusão aguda do fluxo coronariano, é fundamental a restauração imediata da perviabilidade do vaso para limitar a extensão e duração da isquemia. Nesta situação, pode estar indicada a revascularização cirúrgica do miocárdio de emergência. Os autores apresentam caso de um paciente com dissecção iatrogênica do tronco de coronária esquerda durante angioplastia transluminal percutânea, que foi solucionada pela realização de revascularização completa do miocárdio, com resultado satisfatório.

Coronary dissection has a significant morbity and mortality. The ideal management of acute coronary occlusion is the prompt restoration of the vessel patency to limit the extent and duration of ischemia. In the setting of dissection during percutaneous procedure, the usual approach has been emergency aortocoronary bypass surgery. The authors present a case of a patient with left main dissection during percutaneous transluminal coronary angioplasty. This problem was successfully managed with emergent aortocoronary bypass surgery.

A utilização de stents com eluição de fármacos com a finalidade de contornar as desvantagens dos stents não farmacológicos tem sido associada a trombose tardia após a retirada dos agentes antiplaquetários. Relatamos aqui o caso de outra complicação, a formação de aneurisma coronário adjacente ao stent farmacológico, após mais de três anos de implante. As respostas inflamatórias arteriais crônicas locais podem ser as responsáveis pelo enfraquecimento, erosão e formação aneurismática.

The use of drug-eluting stents aiming at by-pass the disadvantage of stainless steel stents have been associated to late thrombosis after withdrawal of anti-platelet agents. We report a case with another complication, the development of a coronary aneurysm in the stent area more than three years after index procedure. Late chronic local inflammatory responses may be responsible for the weakening, erosion and aneusrysm formation.
