Increased RSV-A Bronchiolitis Severity in RSV-Infected Children Admitted to a Reference Center in Catalonia (Spain) Between 2014 and 2018.

Between 2014 and 2018, we evaluated the severity of 687 cases of bronchiolitis caused by respiratory syncytial virus (RSV) in Catalonia, Spain. Compared to RSV-B, RSV-A cases required intensive care (adjusted relative risk (aRR) = 1.44, p < 0.01) and respiratory support (aRR = 1.07, p < 0.01) more often; hospital stay was one day longer (p < 0.01). Subgroup identification may aid clinical evaluation and seasonal healthcare planning.

SARS-COV-2 Infection in Children in Emergency Departments in Spain: A Multicenter Study.

OBJECTIVES: The first cases of infection by SARS-CoV-2 in the Spanish pediatric population were reported on early March 2020. Although most were mild or asymptomatic, new forms of clinical presentation and severity were reported with the evolution of the pandemic. We aimed to describe demographics, clinical features, and management of children with COVID-19 treated in Spanish emergency departments (EDs). METHODS: A multicenter registry including 15 pediatric EDs was carried out. Patients younger than 18 years with confirmed acute SARS-CoV2 infection diagnosed between March and August 2020 were included. RESULTS: Three hundred ninety-five patients were analyzed (median age, 4.3 years). Fifty-five (13.9%) had comorbidities, and 141 (35.7%) a household contact with confirmed COVID-19. The most reported symptoms were fever (85.2%) and cough (41.7%). Fifty (12.5%) were asymptomatic. Seventeen (4.9%) were not well-appearing at presentation. Children underwent a blood test in 26.7% and a chest X-ray in 21.4%; findings were often unremarkable. Symptomatic treatment was prescribed to 80%; 6 (1.7%) received antiviral treatment. Seventy-one (20.6%) were hospitalized, and 3 (0.9%) were admitted to the intensive care unit; no patient died. The main clinical diagnoses were fever without a source (38%) and upper respiratory tract infection (32.2%); 4 (1.1%) presented a multisystem inflammatory syndrome. CONCLUSIONS: Most pediatric COVID-19 cases in EDs during the first months of the pandemic were healthy, well-appearing children, presenting with fever +/- respiratory symptoms. In a significant number of cases, there was household transmission. Most children were managed as outpatients with symptomatic treatment, being exceptional the evolution to a serious illness.

The burden of non-SARS-CoV2 viral lower respiratory tract infections in hospitalized children in Barcelona (Spain): A long-term, clinical, epidemiologic and economic study.

BACKGROUND: Viral lower respiratory tract infections (LRTI) are the leading cause of hospitalization in children. In Catalonia (Spain), information is scarce about the burden of viral LRTIs in paediatric hospitalizations. The aim of this study is to describe epidemiological, clinical, virological and economic features of paediatric hospitalizations due to viral LRTI. METHODS: From October 2012 to December 2020, children aged <16 years admitted to a tertiary paediatric hospital in Catalonia (Spain) with confirmed viral LRTI were included in the study. Virus seasonality, prevalence, age and sex distribution, clinical characteristics, hospital costs and bed occupancy rates were determined. RESULTS: A total of 3,325 children were included (57.17% male, 9.44% with comorbidities) accounting for 4056 hospitalizations (32.47% ≤ 12 months): 53.87% with wheezing/asthma, 37.85% with bronchiolitis and 8.28% with pneumonia. The most common virus was respiratory syncytial virus (RSV) (52.59%). Influenza A was associated with pneumonia (odds ratio [OR] 7.75) and caused longer hospitalizations (7 ± 31.58 days), while RSV was associated with bronchiolitis (OR 6.62) and was the most frequent reason for admission to the paediatric intensive care unit (PICU) (11.23%) and for respiratory support (78.76%). Male sex, age ≤12 months, chronic conditions and bronchiolitis significantly increased the odds of PICU admission. From October to May, viral LRTIs accounted for 12.36% of overall hospital bed days. The total hospitalization cost during the study period was €16,603,415. CONCLUSIONS: Viral LRTIs are an important cause of morbidity, hospitalization and PICU admission in children. The clinical burden is associated with significant bed occupancy and health-care costs, especially during seasonal periods.

Management of Hospitalized Respiratory Syncytial Virus Bronchiolitis in the Pediatric Ward in Spain: Assessing the Impact of a New Clinical Practice Protocol.

BACKGROUND: Bronchiolitis caused by the respiratory syncytial virus (RSV) is the main reason for hospitalization in infants. Supportive care is the mainstay of treatment, and tests are restricted to a few indications. During 2015, our hospital bronchiolitis protocol (2015 HBP) was updated according to the latest practice guidelines. OBJECTIVE: The objective of this study was to assess implementation of the 2015 HBP and the clinical outcome of children aged ≤ 24 months with RSV bronchiolitis admitted to a pediatric ward. METHODS: We compared the use of treatments and tests, hospital length of stay (LOS), and oxygen requirements before implementation of the 2015 HBP (2014-2015 and 2015-2016 seasons) and after implementation (2016-2017 and 2017-2018 seasons). RESULTS: The study population comprised 251 children (44.90%) in the first period and 308 (55.10%) in the second (median age 99 days, interquartile range 44-233). After implementation of the 2015 HBP, a statistically significant reduction was found in the percentage of patients undergoing the following treatments or diagnostic tests: salbutamol, from 57.77 to 31.17% (p < 0.001); epinephrine, from 61.75 to 1.30% (p < 0.001); 3% hypertonic saline, from 70.12 to 6.82% (p < 0.001); antibiotics, from 33.07 to 23.05% (p = 0.008); and chest X-ray, from 43.82 to 31.17% (p = 0.001). No statistically significant reductions were observed in the use of corticosteroids and blood tests. Hospital LOS and oxygen requirements were similar in each period. CONCLUSIONS: Appropriate implementation of the 2015 HBP in the pediatric ward improves the use of medication and chest X-ray without modifying clinical outcomes. However, further efforts are needed to reduce the use of salbutamol, corticosteroids, and blood tests.

Enterovirus-A71 Rhombencephalitis Outbreak in Catalonia: Characteristics, Management and Outcome.

BACKGROUND: Between April and June 2016, an outbreak of rhombencephalitis (RE) caused by enterovirus (EV) A71 was detected in Catalonia, Spain-the first documented in Western Europe. The clinical characteristics and outcome of patients with this condition differed from those reported in outbreaks occurring in Southeast Asia. METHODS: Observational, multicenter study analyzing characteristics, treatment and outcome of patients with EV-A71 rhombencephalitis diagnosed in 6 publicly funded hospitals within the Catalonian Health Institute. A review of clinical characteristics, diagnosis, treatment and outcome of these patients was conducted. RESULTS: Sixty-four patients met the clinical and virologic criteria for rhombencephalitis caused by EV-A71. All patients had symptoms suggesting viral disease, mainly fever, lethargy, ataxia and tremor, with 30% of hand-foot-mouth disease. Intravenous immunoglobulin therapy was given to 44/64 (69%) patients and methylprednisolone to 27/64 (42%). Six patients (9%) required pediatric intensive care unit admission. Three patients had acute flaccid paralysis of 1 limb, and another had autonomic nervous system (ANS) dysfunction with cardiorespiratory arrest. Outcome in all patients (except the patient with hypoxic-ischemic encephalopathy) was good, with complete resolution of the symptoms. CONCLUSIONS: During the 2016 outbreak, rhombencephalitis without ANS symptoms was the predominant form of presentation and most patients showed no hand-foot-mouth disease. These findings contrast with those of other patient series reporting associated ANS dysfunction (10%-15%) and hand-foot-mouth disease (60%-80%). Complete recovery occurred in almost all cases. In light of the favorable outcome in untreated mild cases, therapies for this condition should be reserved for patients with moderate-severe infection. The main relevance of this study is to provide useful information for setting priorities, management approaches and adequate use of resources in future EV-A71 associated rhombencephalitis outbreaks.

Clinical and epidemiological characteristics of patients with influenza A (H1N1) 2009 attended to at the emergency room of a children's hospital.

In June 2009, the first influenza pandemic of the twenty-first century, due to the swine origin influenza A (H1N1) 2009 virus, was declared. This study aimed to describe the epidemiological and clinical features, complications, lethality and risk factors for hospital admission of microbiologically confirmed cases of influenza A (H1N1) 2009 infection seen at the emergency department of a children's hospital. All cases of children with influenza A (H1N1) 2009 viral infection, confirmed microbiologically by real-time reverse transcription polymerase chain reactions and treated in the emergency room between July and December 2009, were prospectively included. Patients were compared according to admission requirement to study variables associated with the risk of hospitalisation. Oseltamivir was the antiviral used for the treatment and its safety was analysed. Four hundred and twelve patients with influenza A (H1N1) 2009 infection were included. The most frequent symptoms were: fever (96%), cough (95%) and coryza (90%). Eighty-five patients (20.6%) were admitted: three to the paediatric intensive care unit and two died. Hospitalised children were younger than those not admitted (median age 5 vs 8 years; p = 0.001). Age under 1 year (OR 6.01; CI 95% 2.77-13.05), pneumonia (OR 7.99; CI 95% 3.50-18.22) and haemoglobinopathy or underlying blood disorders (OR 5.99; CI 95% 1.32-27.30) were statistically significant risk factors for admission. No differences were observed regarding onset of antiviral treatment among admitted and non-admitted patients. Treatment with oseltamivir was well tolerated. In conclusion, the incidence of severe cases and lethality of influenza A (H1N1) 2009 infection were low in our setting, even in a population with risk factors for developing complications.

Debut precoç de malaltia inflamatòria intestinal / Early onset of inflammatory bowel disease

Introducció. La incidència de la malaltia inflamatòriaintestinal està incrementant, així com el nombre de casosde presentació precoç. Per aquest motiu presentem un casde malaltia inflamatòria intestinal de debut el primer anyde vida.Observació clínica. Nen de 15 mesos amb hematoquèziade 5 mesos d’evolució associada a retard pondoestatural.Inicialment, es van dur a terme exploracionscomplementàries dirigides a descartar tant l’etiologia infecciosacom l’al·lèrgica. Analíticament presenta anèmia isignes inflamatoris. Es practica una endoscòpia digestivaalta i baixa amb biòpsies on s’objectiva la presència d’uninfiltrat limfoplasmocitari compatible amb colitis indeterminada.S’inicia tractament amb corticoides, amb ràpidamillora clínica i analítica; posteriorment, un tractament demanteniment amb mesalazina permet la correcció en eldesenvolupament pondoestatural.Comentaris.

Introduction. The incidence of inflammatory bowel disease(IBD), as well as the cases of early presentation, areincreasing. For this reason, we present a case of IBD whichonset occurred during the first year of life.Clinical observation. A 15 mo child presented with a 5-month history of hematochezia and failure to thrive. Initialevaluations included studies for infectious etiologiesand food allergies. The patient had anemia and inflammatorysigns. Upper and lower endoscopies, with multiplebiopsies were performed. Pathology showed the presenceof a lymphoplasmocytic infiltrate consistent with colitis.Treatment with steroids was started, with rapid clinical improvementand normalization of the laboratory parameters.The patient was then started on maintenance withmesalazine, with normalization of the weight and height.Comments. IBD has a nonspecific presentation in earlychildhood. Thus, in cases of gastrointestinal problems oftorpid evolution in which other common etiologies havebeen ruled out, IBD must be considered. Lack of early diagnosismay result in worsening morbidity, such in the caseunder discussion, where the failure to thrive was not correcteduntil appropriate treatment was administered
