RESUMO

Introduction: Multisystem inflammatory syndrome in children associated with coronavirus disease 2019 (MIS-C), a novel hyperinflammatory condition secondary to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, is associated with severe outcomes such as coronary artery aneurysm and death. Methods: This multicenter, retrospective, observational cohort study including eight centers in Mexico, aimed to describe the clinical characteristics and outcomes of patients with MIS-C. Patient data were evaluated using latent class analysis (LCA) to categorize patients into three phenotypes: toxic shock syndrome-like (TSSL)-MIS-C, Kawasaki disease-like (KDL)-MIS-C, and nonspecific MIS-C (NS-MIS-C). Risk factors for adverse outcomes were estimated using multilevel mixed-effects logistic regression. Results: The study included 239 patients with MIS-C, including 61 (26%), 70 (29%), and 108 (45%) patients in the TSSL-MIS-C, KDL-MIS-C, and NS-MIS-C groups, respectively. Fifty-four percent of the patients were admitted to the intensive care unit, and 42%, 78%, and 41% received intravenous immunoglobulin, systemic glucocorticoids, and anticoagulants, respectively. Coronary artery dilatation and aneurysms were found in 5.7% and 13.2% of the patients in whom coronary artery diameter was measured, respectively. Any cause in-hospital mortality was 5.4%. Hospitalization after ten days of symptoms was associated with coronary artery abnormalities (odds ratio [OR] 1.6, 95% confidence interval [CI] 1.2-2.0). Age ≥10 years (OR: 5.6, 95% CI: 1.4-2.04), severe underlying condition (OR: 9.3, 95% CI: 2.8-31.0), platelet count <150,000 /mm3 (OR: 4.2, 95% CI: 1.2-14.7), international normalized ratio >1.2 (OR: 3.8, 95% CI: 1.05-13.9), and serum ferritin concentration >1,500 mg/dl at admission (OR: 52, 95% CI: 5.9-463) were risk factors for death. Discussion: Mortality in patients with MIS-C was higher than reported in other series, probably because of a high rate of cases with serious underlying diseases.

RESUMO

La enfermedad de Kawasaki es una vasculitis aguda, sistémica, de curso autolimitado que afecta con más frecuencia a lactantes y preescolares, y constituye la principal causa de cardiopatía adquirida en los países desarrollados. En Colombia se presentan múltiples casos que son diagnosticados y tratados en hospitales de segundo y tercer nivel de complejidad, los cuales en algunas oportunidades son remitidos a evaluación cardiológica por ecocardiografía. En la actualidad no se cuenta con estadísticas nacionales ni locales, lo cual puede favorecer que muchos de los casos no sean diagnosticados oportunamente, pues se confunde con facilidad con enfermedades exantemáticas. En este artículo se hace una revisión sobre los principales aspectos de la enfermedad.


Kawasaki disease is an acute, systemic, self-limited vasculitis. Affects most commonly infants and preschoolers, and is the leading cause of acquired heart disease in developed countries. In Colombia, there are multiple cases that are diagnosed and treated in hospital of second and third level of complexity, which are referred to cardiac evaluation by echocardiography, in some cases. At present we have no national or local statistics and this is one factor why, many cases are not diagnosed promptly, because it is easily confused with rash diseases there is no clear criteria of the principal diagnosis of the disease. This article is a review on the main aspects of the disease.

RESUMO

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.

RESUMO

We report a 16 year old male with a history of angina on exertion. A treadmill exercise test was positive for ischemia in concordance with a Thallium-201 scintigraphy showing a septal and infero-posterior reversible myocardial perfusi¢n defect. Coronary angiography disclosed severe aneurysmal coronary artery disease. Bilateral internal mammary coronary artery bypass grafting was successfully performed. Kawasaki disease is the most likely etiology, although not confirmed.
