Digital ischemia as the initial presentation of catastrophic antiphospholipid syndrome.

Catastrophic antiphospholipid syndrome is an infrequent disease in children, but of major relevance because of its high morbidity and mortality. We report the case of a child with digital ischaemia in whom, after aetiological screening, the diagnosis of catastrophic antiphospholipid syndrome was made.

Isquemia digital como forma de presentación de síndrome antifosfolípido catastrófico pediátrico / Digital Ischemia as the Initial Presentation of Catastrophic Antiphospholipid Syndrome

El síndrome antifosfolípido catastrófico es una entidad infrecuente en Pediatría, pero con importante relevancia dada la elevada morbimortalidad. Se expone el caso de un niño con isquemia digital en el que, tras realizar despistaje etiológico de diferentes entidades infecciosas e inflamatorias, se llegó al diagnóstico de síndrome antifosfolípido catastrófico primario.(AU)

Crohn's disease in a patient with systemic onset juvenile idiopathic arthritis. Association or associated side effect of treatment?

The progression of systemic-onset juvenile idiopathic arthritis (JIAs) to the different forms of presentation of inflammatory bowel disease is extremely rare. We present the first report of a patient with SJIA that progressed to Crohn's disease in which mutations have been detected in genes responsible for the adequate regulation of the innate immune system.

Adiposity Is Related to Inflammatory Disease Activity in Juvenile Idiopathic Arthritis.

OBJECTIVE: To identify factors associated with the higher proportion of fatty tissue and overweight/obesity observed in patients with juvenile idiopathic arthritis (JIA). PATIENTS AND METHODS: We performed a cross-sectional study of 80 JIA patients aged 4-15 years with 80 age- and sex-matched healthy controls. Body composition was assessed using dual-energy x-ray absorptiometry. The 27-joint Juvenile Arthritis Disease Activity score (JADAS27) was calculated. Two multivariate models were constructed to identify factors associated with overweight/obesity and fat mass index (FMI). RESULTS: No differences were found between cases and controls in body mass index (BMI) or body composition. However, compared with controls, patients with a high inflammatory activity (JADAS27 > 4.2 for oligoarticular JIA or >8.5 for polyarticular disease) had higher values for BMI (p = 0.006); total fat mass (p = 0.003); FMI (p = 0.001); and fat in the legs (p = 0.001), trunk (p = 0.001), and arms (p = 0.002). The factors associated with overweight/obesity in patients were the duration of therapy with biological drugs, measured in months (OR [95% CI] = 1.12 [1.02-1.04]; p = 0.037), and physical activity (OR [95% CI] = 0.214 [0.07-0.68]; p = 0.010), while the factors associated with FMI were age (ß [95% CI] = 0.30 [0.17-1.41]; p = 0.014), JADAS27 (ß [95% CI] = 0.45 [0.16-1.08]; p = 0.009), and physical activity (ß [95% CI] = -0.22 [-5.76 to 0.29]; p = 0.031). CONCLUSION: Our study revealed no differences between JIA patients with well-controlled disease and low disability and the healthy population in BMI or body composition. Furthermore, the association observed between inflammatory activity and adiposity could be responsible for poorer clinical course.

Características clínico-epidemiológicas de la neumonía por Pneumocystis jirovecii en un hospital de tercer nivel en España / Clinical-epidemiological characteristics of Pneumocystis jirovecii pneumonia in a tertiary hospital in Spain

Introducción: La infección por VIH era el principal factor de riesgo para presentar neumonía por Pneumocystis jirovecii (NPJ). En la actualidad, las características clínico-epidemiológicas de la NPJ en niños han cambiado, existiendo pocos estudios en este sentido. Métodos: Realizamos un estudio observacional retrospectivo en pacientes pediátricos diagnosticados de NPJ durante 17 años en un hospital de tercer nivel en España. Resultados: Se recogió a 23 pacientes, de los que 11/23 (47,8%) presentaban enfermedad hematológica, 5/23 (21,7%) inmunodeficiencia primaria y 4/23 (17,4%) infección por VIH. Recibían profilaxis con trimetoprima-sulfametoxazol (TMP-SMX) 11/23 pacientes (47,8%). Todos recibieron tratamiento con TMP-SMX y 18/23 (78,3%), glucocorticoides sistémicos. Fallecieron 6/23 pacientes (26,1%), de los que 1/6 (16,7%) presentaba infección por VIH. En los pacientes no VIH con mayor leucocitosis, mayor retención de CO2 y mayor frecuencia cardíaca al inicio, se evidenció mayor mortalidad, diferencias no objetivadas en pacientes con VIH. No se encontraron diferencias en mortalidad en relación con el factor predisponente, empleo de TMP-SMX ni tratamiento con glucocorticoides. Conclusiones: En la actualidad, los pacientes pediátricos con neoplasias hematológicas constituyen el principal grupo de riesgo de desarrollar NPJ en este grupo etario. No hemos encontrado diferencias de mortalidad entre pacientes con o sin infección por VIH como factor predisponente. Entre los pacientes no VIH la mortalidad fue mayor en aquellos que presentaron mayor leucocitosis, mayor retención de CO2 y mayor frecuencia cardíaca al inicio. No se objetivó mejor pronóstico en pacientes que recibían profilaxis con TMP-SMX previamente al desarrollo de la NPJ ni en los que recibieron glucocorticoides sistémicos como parte del tratamiento.

Introduction: HIV infection was the main risk of suffering Pneumocystis jirovecii pneumonia (PJP). The clinical-epidemiological characteristics of PJP have currently changed, with there being few studies on this. Methods: A retrospective observational study was carried out on paediatric patients diagnosed with PJP over a 17 year period in a third level hospital in Spain. Results: A total of 23 patients were included, of whom 7/23 (47.8%) suffered a haematological disease, 5/23 (21.7%) a primary immunodeficiency, and 4/23 (17.4%) an HIV infection. Prophylaxis with trimethoprim-sulfamethoxazole (TMP-SMX) was received by 11/23 (47.8%) patients. All were treated with TMP-SMX and 18/23 (78.3%) with systemic glucocorticoids. There were 6(26.1%) deaths, of which one of them (16.7%) suffered an HIV infection. A higher mortality was seen in the non-HIV patients with greater leucocytosis, greater CO2 retention, and a higher heart rate at onset, differences not observed in HIV patients. No differences were found in mortality in relation to the predisposing factor, use of pTMP-SMX, or treatment with glucocorticoids. Conclusions: Paediatric patients with haematological cancers are currently the main risk group of developing PJP in this age group. No differences were found in mortality between patients with or without HIV infection as predisposing factor. The mortality among non-HIV patients was higher in those that had greater leucocytosis, greater CO2 retention, and increased heart rate at onset. A better prognosis was not seen in patients that received prophylaxis with TMP-SMX prior to the development of the PJP, or in those that received glucocorticoids as part of the treatment. (AU)

Skin manifestations during the COVID-19 pandemic in the pediatric emergency department.

BACKGROUND: The role of SARS-CoV-2 as the cause of chilblains in children remains a matter of debate but it is important to elucidate it for patient isolation and contact tracing. We sought to define the etiology, clinical presentation, time course, and outcomes of children presenting to the emergency department (ED) with cutaneous manifestations shortly after the first pandemic peak of COVID-19 in Spain. METHODS: A prospective, observational study in children <15 years of age evaluated for skin lesions in the EDs of three pediatric hospitals. Children underwent a comprehensive work-up including tests for SARS-CoV-2 antibodies and polymerase chain reaction (PCR), and serology and PCR tests for other viruses and bacteria. A 1 month follow-up visit was conducted. RESULTS: From April 14 through May 8, 2020, we enrolled 62 children. Of those, 34 had acro-ischemic skin lesions and 28 had a variety of skin rashes. Overall, 40% of children had mild systemic symptoms. Children with chilblains were older, had pain more frequently and a more prolonged duration of skin lesions, while those with non-specific rashes had fever more frequently. Lesions were resolved in 75% of children at follow up. Five patients demonstrated SARS-CoV-2 antibodies, and none tested positive with PCR. Three additional patients tested positive with PCR for rhinovirus, Mycoplasma pneumoniae and Chlamydia pneumoniae. CONCLUSIONS: The number of ED visits for chilblains, which are rare in pediatrics, was high soon after the first peak of COVID-19 in Spain. The disease course was self-limited, outcomes were favorable, and the possibility of viral transmission was negligible as all patients tested negative for SARS-CoV-2 by PCR.
