Tuberculosis screening after detection of a case in a paediatric haemato-oncology unit in a low prevalence country.

BACKGROUND: There are no guidelines to screen haemato-oncologic children when a tuberculosis (TB) outbreak is suspected. METHODS: After exposition to an adult with active TB, children exposed from a haemato-oncology unit were screened according to immunosuppression status and time of exposure. Until an evaluation after 8-12 weeks from last exposure, isoniazid was indicated to those with negative initial work-up. RESULTS: After 210 interventions, we detected a case of pulmonary TB, and another with latent TB infection. Pulmonary findings and treatment approach were challenging in some patients. CONCLUSIONS: The TB screening of oncologic children required a multidisciplinary approach, and clinicians managed challenging situations.

[Spanish consensus document on diagnosis, stabilisation and treatment of pediatric multisystem inflammatory syndrome related to SARS-CoV-2 (SIM-PedS)]. / Documento español de consenso sobre diagnóstico, estabilización y tratamiento del síndrome inflamatorio multisistémico pediátrico vinculado a SARS-CoV-2 (SIM-PedS).

A new paediatric multisystem inflammatory syndrome, linked to SARS-CoV-2, has been described. The clinical picture is variable and is associated with an active or recent infection due to SARS-CoV-2. A review of the existing literature by a multidisciplinary group of paediatric specialists is presented in this document. Later, they make recommendations on the stabilisation, diagnosis, and treatment of this syndrome.

Severe Rifampicin-induced Vitamin K Deficiency Coagulopathy in a Child.

An 8-month-old child under tuberculosis treatment presented with multiple ecchymotic lesions. A severe coagulopathy was evidenced compatible with vitamin K deficiency [II (3%), VII (2%), IX (3%) and X (1%)]. It was reversed with vitamin K and plasma administration. Rifampicin-induced vitamin K deficiency is very rare, reported only once before, possibly related to an inhibition of vitamin K cycle.

Epidemiological and clinical features of Kawasaki disease in Spain over 5 years and risk factors for aneurysm development. (2011-2016): KAWA-RACE study group.

BACKGROUND: Kawasaki disease (KD) is an acute self-limited systemic vasculitis of unknown etiology affecting mainly children less than 5 years of age. Risk factors for cardiac involvement and resistance to treatment are insufficiently studied in non-Japanese children. OBJECTIVE: This study aimed to investigate the epidemiology, clinical features and risk factors for resistance to treatment and coronary artery lesions (CAL) in KD in Spain. METHODS: Retrospective study (May 2011-June 2016) of all patients less than 16 years of age diagnosed with KD included in KAWA-RACE network (84 Spanish hospitals). RESULTS: A total of 625 cases were analyzed, 63% were males, 79% under 5 year-olds and 16.8% younger than 12 months. On echocardiographic examination CAL were the most frequent findings (23%) being ectasia the most common (12%). Coronary aneurysms were diagnosed in 9.6%, reaching 20% in infants under 12 months (p<0.001). A total of 97% of the patients received intravenous immunoglobulin (IVIG) with a median number of days from fever onset to IVIG administration of 7.2. A second dose was given to 15.7% and steroids to 14.5% patients. Only 1.4% patients received infliximab. No deaths were reported. A multivariate analysis identified anemia, hypoalbuminemia, hyponatremia, higher creatinine and procalcitonin as independent risk factors for treatment failure and length under 103 cm, hemoglobin < 10.2 mg/dL, platelets > 900,000 cells/mm3, maximum temperature < 39.5°C, total duration of fever > 10 days and fever before treatment ≥ 8 days as independent risk factors for developing coronary aneurysms. CONCLUSIONS: In our population, children under 12 months develop coronary aneurysms more frequently and children with KD with anemia and leukocytosis have high risk of cardiac involvement. Adding steroids early should be considered in those patients, especially if the treatment is not started before 8 days of fever. A score applicable to non-Japanese children able to predict the risk of aneurysm development and IVIG resistance is necessary.

[Previous or coincident infections with suspected Kawasaki disease. Should we change our approach?] / Infecciones previas o coincidentes con la sospecha de enfermedad de Kawasaki ¿debemos cambiar nuestra actitud?

INTRODUCTION: Kawasaki disease (KD) is a multisystem vasculitis associated with coronary artery abnormalities. Infections could be a trigger of the inflammation. The main aim of this study was to describe the presence of infections in children with KD, and to analyse the clinical characteristics and the presence of coronary abnormalities in these cases. PATIENTS AND METHODS: A retrospective study was performed within the Kawasaki Diseases Network (KAWA-RACE (2011-2016). An analysis was performed that included patients with positive microbiological findings (PMF) during the acute phase, as well as those with a previous recent infection (PRI) during the 4 weeks preceding KD diagnosis. RESULTS: The study included total of 621 children with KD, with PMF being found in 101 (16.3%) patients, and a PRI in 107 (17.2%). Significantly less echocardiographic abnormalities were found in the in the group with a PRI, when compared to those without a PRI (23 vs. 35%, P=.01) and also a lower proportion of overall coronary artery lesions (16 vs. 25%, P=.054). No significant differences were found in the proportion of aneurysms in either of these groups (PRI or PMF) when compared to those without infection. CONCLUSIONS: In the present study, no differences were found in the incidence of coronary aneurysms in either of the groups, with or without PRI or PMF. Therefore, if KD is suspected, appropriate treatment should be started despite having a confirmed infection.

INTRODUCCIÓN: La enfermedad de Kawasaki (EK) es una vasculitis multisistémica asociada a lesiones en las arterias coronarias. Las infecciones podrían ser un desencadenante de la inflamación. Nuestro objetivo fue describir la presencia de infecciones en los niños con EK y analizar las características clínicas y la presencia de alteraciones coronarias en estos casos. PACIENTES Y MÉTODOS: Análisis retrospectivo de los pacientes incluidos en la red KAWA-RACE entre 2011 y 2016. Se estudió tanto a los pacientes que tuvieron una identificación microbiológica confirmada (IMC) en el periodo agudo como a los que presentaron antecedente de infección previa reciente (IPR) las 4 semanas anteriores. RESULTADOS: Se incluyó a un total de 621 niños, de los cuales 101 (16,3%) tuvieron una IMC y 107 (17,2%) una IPR. Encontramos una significativa menor afectación ecocardiográfica en el grupo de IPR respecto a los niños sin infección previa (23 vs. 35%; p 0,01), con menor proporción no significativa de las alteraciones coronarias globales (16 vs. 25%; p 0,054). Sin embargo, no se detectaron diferencias en la proporción de aneurismas en ninguno de los 2 grupos (IMC o IPR) respecto al resto de los pacientes sin infecciones asociadas. CONCLUSIONES: En nuestro estudio no encontramos diferencias en la incidencia de aneurismas coronarios en niños con y sin IMC o IPR, por lo que ante la sospecha de EK debe iniciarse siempre tratamiento, aunque se tenga infección confirmada microbiológicamente.
