RESUMO
OBJECTIVE: Juvenile systemic lupus erythematosus (j-SLE) is a rare chronic auto-immune disease involving several organs. Neuropsychiatric (NP) SLE (NPSLE) is frequent in j-SLE and associated with increased morbidity/mortality. Although NPSLE classification criteria exist, attributing NP features to j-SLE remains a major challenge. The study objective is to thoroughly describe j-NPSLE patients and assist in their diagnosis. METHODS: This is a 4-year retrospective monocentric study of j-SLE patients. NP events were attributed to j-SLE using standardised diagnostic criteria and multidisciplinary paediatric clinical expertise. Clinical features, brain magnetic resonance imaging (MRI)s and samples analysis including cerebrospinal fluid were assessed. A risk of j-NPSLE score was developed based on multivariable logistic regression analysis. RESULTS: Of 39 patients included, 44% were identified as having j-NPSLE. J-NPSLE diagnosis was established at the onset of j-SLE in 59% of patients. In addition to frequent kidney involvement (76%) and chilblains (65%), all j-NPSLE patients displayed psychiatric features: cognitive symptoms (82%), hallucinations (76%), depressed mood (35%), acute confused state (18%) and catatonia (12%). Neurological involvement was often mild and nonspecific, with headache (53%) in about half of the patients. The main features reported on brain MRI were nonspecific T2/FLAIR white matter hyperintensities (65%), and cerebral atrophy (88%). Upon immunosuppressive treatment, clinical improvement of NP features was observed in all j-NPSLE patients. The score developed to attribute j-NPSLE probability, guide further investigations and appropriate treatments is based on hallucinations, memory, sleep and renal involvement (Sensitivity: 0.95 Specificity: 0.85). Cerebrospinal fluid (CSF) neopterin assessment increases the score sensitivity and specificity. CONCLUSION: Physicians should carefully and systematically assess the presence of NP features at diagnosis and early stages of j-SLE. For j-NPSLE patients with predominant psychiatric features, a multidisciplinary collaboration, including psychiatrists, is essential for the diagnosis, management and follow-up.

RATIONALE: Use of life support with extracorporeal membrane oxygenation (ECMO) is associated with brain injury. However, the consequences of these injuries on subsequent neurologic development and health-related quality of life (HRQoL) are poorly described in children. OBJECTIVES: The aim of this preliminary study was to describe short- and long-term neurologic outcomes in survivors of ECMO, as well as their HRQoL. DESIGN: Retrospective identified cohort with contemporary evaluations. SETTING: Necker Children's Hospital academic PICU. PATIENTS: Forty survivors who underwent ECMO (October 2014 to January 2020) were included in follow-up assessments in May 2021. INTERVENTIONS: None. MEASUREMENT AND MAIN RESULTS: We first reviewed the outcomes of ECMO at the time of PICU discharge, which included a summary of neurology, radiology, and Pediatric Overall/Cerebral Performance Category (POPC/PCPC) scores. Then, in May 2021, we interviewed parents and patients to assess HRQoL (Pediatric Quality of Life Inventory [PedsQL]) and POPC/PCPC for children 3 years old or older, and Denver II test (DTII) for younger children. An evaluation of DTII in the youngest patients 1 year after ECMO decannulation was also added. Median age at ECMO was 1.4 years (interquartile range [IQR], 0.4-6 yr). Thirty-five children (88%) underwent a venoarterial ECMO. At PICU discharge, 15 of 40 patients (38%) had neurologic impairment. Assessment of HRQoL was carried out at median of 1.6 years (IQR, 0.7-3.3 yr) after PICU discharge. PedsQL scores were over 70 of 100 for all patients (healthy peers mean results: 80/100), and scores were like those published in patients suffering with chronic diseases. In May 2021, seven of 15 patients had a normal DTII, and 36 of 40 patients had a POPC/PCPC score less than or equal to 3. CONCLUSIONS: None of our patients presented severe disability at long term, and HRQoL evaluation was reassuring. Considering the risk of neurologic impairment after ECMO support, a systematic follow-up of these high-risk survivor patients would be advisable.

INTRODUCTION: Juvenile systemic lupus erythematosus (j-SLE) is a rare chronic autoimmune disease affecting multiple organs. Ranging from minor features, such as headache or mild cognitive impairment, to serious and life-threatening presentations, j-neuropsychiatric SLE (j-NPSLE) is a therapeutic challenge. Thus, the diagnosis of NPSLE remains difficult, especially in pediatrics, with no specific biomarker of the disease yet validated. OBJECTIVES: To identify central nervous system (CNS) disease biomarkers of j-NPSLE. METHODS: A 5-year retrospective tertiary reference monocentric j-SLE study. A combination of standardized diagnostic criteria and multidisciplinary pediatric clinical expertise was combined to attribute NP involvement in the context of j-SLE. Neopterin and interferon-alpha (IFN-α) protein levels in cerebrospinal fluid (CSF) were assessed, together with routine biological and radiological investigations. RESULTS: Among 51 patients with j-SLE included, 39% presented with j-NPSLE. J-NPSLE was diagnosed at onset of j-SLE in 65% of patients. No specific routine biological or radiological marker of j-NPSLE was identified. However, CSF neopterin levels were significantly higher in active j-NPSLE with CNS involvement than in j-SLE alone (p = 0.0008). Neopterin and IFN-α protein levels in CSF were significantly higher at diagnosis of j-NPSLE with CNS involvement than after resolution of NP features (respectively p = 0.0015 and p = 0.0010) upon immunosuppressive treatment in all patients tested (n = 10). Both biomarkers correlated strongly with each other (Rs = 0.832, p < 0.0001, n = 23 paired samples). CONCLUSION: CSF IFN-α and neopterin constitute promising biomarkers useful in the diagnosis and monitoring of activity in j-NPSLE.

OBJECTIVES: To describe the policies about parent visiting and involvement in care during admission to French PICUs. DESIGN: A structured questionnaire was emailed to the chief of each of 35 French PICUs. Data about visiting policies, involvement in care, evolution of policies, and general characteristics were collected from April 2021 to May 2021. A descriptive analysis was conducted. SETTING: Thirty-five PICUs in France. PATIENTS: None. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Twenty-nine of 35 (83%) PICUs replied. Twenty-four-hour access for parents was reported for all PICUs responding. Other allowed visitors were grandparents (21/29, 72%) and siblings (19/29, 66%) with professional support. Simultaneous visits were restricted to two visitors in 83% (24/29) of PICUs. Family presence was always permitted during medical rounds for 20 of 29 (69%) PICUs. Most of the units rarely or never allowed parental presence during the most invasive procedures, such as central venous catheter placement (18/29, 62%) and intubation (22/29, 76%). CONCLUSIONS: Unrestricted access to the PICU, for both parents, was available in all responding French units. There were, however, restrictions on the number of visitors and the presence of other family members at the bedside. Moreover, permission for parental presence during care procedures was heterogenous, and mainly restricted. National guidelines and educational programs are needed to support family wishes and promote acceptance by healthcare providers in French PICUs.

Whilst upregulation of type I interferon (IFN) signaling is common across the type I interferonopathies (T1Is), central nervous system (CNS) involvement varies between these disorders, the basis of which remains unclear. We collected cerebrospinal fluid (CSF) and serum from patients with Aicardi-Goutières syndrome (AGS), STING-associated vasculopathy with onset in infancy (SAVI), presumed monogenic T1Is (pT1I), childhood systemic lupus erythematosus with neuropsychiatric features (nSLE), non-IFN-related autoinflammation (AI) and non-inflammatory hydrocephalus (as controls). We measured IFN-alpha protein using digital ELISA. Eighty-two and 63 measurements were recorded respectively in CSF and serum of 42 patients and 6 controls. In an intergroup comparison (taking one sample per individual), median CSF IFN-alpha levels were elevated in AGS, SAVI, pT1I, and nSLE compared to AI and controls, with levels highest in AGS compared to all other groups. In AGS, CSF IFN-alpha concentrations were higher than in paired serum samples. In contrast, serum IFN was consistently higher compared to CSF levels in SAVI, pT1I, and nSLE. Whilst IFN-alpha is present in the CSF and serum of all IFN-related diseases studied here, our data suggest the primary sites of IFN production in the monogenic T1I AGS and SAVI are, respectively, the CNS and the periphery. These results inform the diagnosis of, and future therapeutic approaches to, monogenic and multifactorial T1Is.

BACKGROUND: Current data suggest that COVID-19 is less frequent in children, with a milder course. However, over the past weeks, an increase in the number of children presenting to hospitals in the greater Paris region with a phenotype resembling Kawasaki disease (KD) has led to an alert by the French national health authorities. METHODS: Multicentre compilation of patients with KD in Paris region since April 2020, associated with the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ('Kawa-COVID-19'). A historical cohort of 'classical' KD served as a comparator. RESULTS: Sixteen patients were included (sex ratio=1, median age 10 years IQR (4·7 to 12.5)). SARS-CoV-2 was detected in 12 cases (69%), while a further three cases had documented recent contact with a quantitative PCR-positive individual (19%). Cardiac involvement included myocarditis in 44% (n=7). Factors prognostic for the development of severe disease (ie, requiring intensive care, n=7) were age over 5 years and ferritinaemia >1400 µg/L. Only five patients (31%) were successfully treated with a single intravenous immunoglobulin (IVIg) infusion, while 10 patients (62%) required a second line of treatment. The Kawa-COVID-19 cohort differed from a comparator group of 'classical' KD by older age at onset 10 vs 2 years (p<0.0001), lower platelet count (188 vs 383 G/L (p<0.0001)), a higher rate of myocarditis 7/16 vs 3/220 (p=0.0001) and resistance to first IVIg treatment 10/16 vs 45/220 (p=0.004). CONCLUSION: Kawa-COVID-19 likely represents a new systemic inflammatory syndrome temporally associated with SARS-CoV-2 infection in children. Further prospective international studies are necessary to confirm these findings and better understand the pathophysiology of Kawa-COVID-19. Trial registration number NCT02377245.

BACKGROUND: Iatrogenic induced hypothyroidism had been described in newborns and more particularly in preterm infants after cutaneous or intravenous exposure to iodine. CASE-DIAGNOSIS : We reported a new risk of iodine intoxication with the cases of two newborns who developed hypothyroidism after intra vesical iodine injection during a cystography, which was performed to confirm antenatal diagnosis of posterior urethral valves (PUV). The newborns both developed transient hypothyroidism due to an iodine overdose. CONCLUSIONS: These two observations suggest that voiding cystourethrography (VCUG) should be carefully considered in newborns with severe uropathy, particularly in the case of renal insufficiency. If indicated, thyroid function should be monitored in the following weeks, and in case of hypothyroidism treatment should be started.

OBJECTIVE: It is now well established that post-intensive care syndrome is frequent in critically ill children after discharge from the pediatric intensive care unit (PICU). Nevertheless, post-intensive care follow-up is highly heterogenous worldwide and is not considered routine care in many countries. The purpose of this viewpoint was to report the reflections of the French PICU society working group on how to implement post-PICU follow-up. METHODS: A working group was set up within the Groupe Francophone de Reanimation et d'Urgences Pédiatriques (GFRUP) to provide conceptual and practical guidance for developing post-PICU follow-up. The working group included psychologists, PICU physicians, physiotherapists, and nurses, from different French PICUs. Five virtual meetings have been held. RESULTS: First, we described in this work the objectives of the follow-up program and the population to be targeted. We also provided a framework to implement post-PICU follow-up in clinical practice. Finally, we detailed the potential obstacles and challenges to consider. CONCLUSION: Although implementing a post-PICU follow-up program is a challenge, the benefits could be significant for both patient and relatives, as well as for the health care professionals involved.

BACKGROUND: Kawasaki disease is an acute febrile systemic childhood vasculitis, which is suspected to be triggered by respiratory viral infections. We aimed to examine whether the ongoing COVID-19 epidemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is associated with an increase in the incidence of Kawasaki disease. METHODS: We did a quasi-experimental interrupted time series analysis over the past 15 years in a tertiary paediatric centre in the Paris region, a French epicentre of the COVID-19 outbreak. The main outcome was the number of Kawasaki disease cases over time, estimated by quasi-Poisson regression. In the same centre, we recorded the number of hospital admissions from the emergency department (2005-2020) and the results of nasopharyngeal multiplex PCR to identify respiratory pathogens (2017-2020). These data were compared with daily hospital admissions due to confirmed COVID-19 in the same region, recorded by Public Health France. FINDINGS: Between Dec 1, 2005, and May 20, 2020, we included 230 patients with Kawasaki disease. The median number of Kawasaki disease hospitalisations estimated by the quasi-Poisson model was 1·2 per month (IQR 1·1-1·3). In April, 2020, we identified a rapid increase of Kawasaki disease that was related to SARS-CoV-2 (six cases per month; 497% increase [95% CI 72-1082]; p=0·0011), starting 2 weeks after the peak of the COVID-19 epidemic. SARS-CoV-2 was the only virus circulating intensely during this period, and was found in eight (80%) of ten patients with Kawasaki disease since April 15 (SARS-CoV-2-positive PCR or serology). A second peak of hospital admissions due to Kawasaki disease was observed in December, 2009 (six cases per month; 365% increase ([31-719]; p=0.0053), concomitant with the influenza A H1N1 pandemic. INTERPRETATION: Our study further suggests that viral respiratory infections, including SAR-CoV-2, could be triggers for Kawasaki disease and indicates the potential timing of an increase in incidence of the disease in COVID-19 epidemics. Health-care providers should be prepared to manage an influx of patients with severe Kawasaki disease, particularly in countries where the peak of COVID-19 has recently been reached.

OBJECTIVE: Traveller's diarrhoea (TD) is one of the most frequent illnesses affecting children returning from tropical countries. The purpose of this study was to assess the distribution of pathogens associated with TD in children using a multiplex PCR assay on stool samples. DESIGN: All the children admitted for TD in two university hospitals from 1 August to 15October during 2014 and 2015 were included in a prospective study. Stool samples were tested by a multiplex PCR FilmArray GI panel detecting 22 pathogens. Performances for the detection of major enteropathogenic bacteria (Salmonella, Shigella and Campylobacter spp) by multiplex PCR and conventional culture methods were compared. The prevalence of extended spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae was also determined. RESULTS: Fifty-nine children were included. In 58 cases (98%), at least one pathogen was identified, including 9 different enteropathogenic bacteria, 5 viruses and 2 parasites. Multiplex PCR enhanced the enteropathogenic bacteria detection by 25%. The most frequent pathogens were enteroaggregative Escherichia coli (n=32), enteropathogenic E. coli (n=26), enterotoxigenic E. coli (n=19), Salmonella enterica, enteroinvasive E. coli/Shigella (n=16 each), Cryptosporidium, sapovirus (n=11 each), Campylobacter jejuni, norovirus (n=10 each), rotavirus (n=9), Giardia (n=8) and Shiga-toxin-producing E. coli (n=4). Fifty-two coinfections were observed, notably including bacteria and viruses (n=21), multiple bacteria (n=14), or bacteria and parasites (n=10). ESBL were detected in 28 cases. Multiplex PCR could optimise the number of treated patients by 27% compared with stool cultures. CONCLUSION: Multiplex PCR on stools revealed a high prevalence of diverse enteric pathogens and coinfections in children with TD. Major enteropathogenic bacteria were more frequently detected by multiplex PCR compared with conventional culture. Finally, this technique allows the start of appropriate and early antibiotic treatment and seems to optimise the number of correctly treated patients.
