Early Impact of Severe Acute Respiratory Syndrome Coronavirus 2 on Pediatric Clinical Research: A Pan-European and Canadian Snapshot in Time.

OBJECTIVE: To capture the early effects of the coronavirus disease 2019 (COVID-19) pandemic on pediatric clinical research. STUDY DESIGN: Pediatric clinical research networks from 20 countries and 50 of their affiliated research sites completed two surveys over one month from early May to early June 2020. Networks liaised with their affiliated sites and contributed to the interpretation of results through pan-European group discussions. Based on first detection dates of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), countries formed 1 early detecting and 1 late detecting cluster. We tested the hypothesis that this clustering influenced clinical research. RESULTS: Research sites were first impacted by the pandemic in mid-March 2020 (March 16 ± 10 days, the same date as lockdown initiation; P = .99). From first impact up until early June, site initiation and feasibility analysis processes were affected for >50% of the sites. Staff were redirected to COVID-19 research for 44% of the sites, and 75.5% of sites were involved in pediatric COVID-19 research (only 6.3% reported COVID-19 cases in their other pediatric trials). Mitigation strategies were used differently between the early and late detecting country clusters and between countries with and without a pediatric COVID-19 research taskforce. Positive effects include the development of teleworking capacities. CONCLUSIONS: Through this collaborative effort from pediatric research networks, we found that pediatric trials were affected and conducted with a range of unequally applied mitigations across countries during the pandemic. The global impact might be greater than captured. In a context where clinical research is increasingly multinational, this report reveals the importance of collaboration between national networks.

Method of Blood Pressure Measurement in Neonates and Infants: A Systematic Review and Analysis.

OBJECTIVES: To determine the recommended blood pressure (BP) measurement methods in neonates after systematically analyzing the literature regarding proper BP cuff size and measurement location and method. STUDY DESIGN: A literature search was conducted in MEDLINE, PubMed, Embase, Cochrane Library, and CINAHL from 1946 to 2017 on BP in neonates <3 months of age (PROSPERO ID CRD42018092886). Study data were extracted and analyzed with separate analysis of Bland-Altman studies comparing measurement methods. RESULTS: Of 3587 nonduplicate publications identified, 34 were appropriate for inclusion in the analysis. Four studies evaluating BP cuff size support a recommendation for a cuff width to arm circumference ratio of approximately 0.5. Studies investigating measurement location identified the upper arm as the most accurate and least variable location for oscillometric BP measurement. Analysis of studies using Bland-Altman methods for comparison of intra-arterial to oscillometric BP measurement show that the 2 methods correlate best for mean arterial pressure, whereas systolic BP by the oscillometric method tends to overestimate intra-arterial systolic BP. Compared with intra-arterial methods, systolic BP, diastolic BP, and mean arterial pressure by oscillometric methods are less accurate and precise, especially in neonates with a mean arterial pressure <30 mm Hg. CONCLUSIONS: Proper BP measurement is critical in neonates with naturally lower BP and attention to BP cuff size, location, and method of measurement are essential. With decreasing use of intra-arterial catheters for long-term BP monitoring in neonates, further studies are urgently needed to validate and develop oscillometric methodology with enhanced accuracy.

Suspected adverse drug reactions reported for Brazilian children: cross-sectional study / Suspeitas de reações adversas a medicamento relatadas em crianças brasileiras: estudo transversal

ABSTRACT Objective: To assess spontaneous reports of suspected adverse drug reactions in children aged 0-12 years from the Brazilian Health Regulatory Agency between 2008 and 2013. Methods: A cross-sectional study on suspected adverse drug reactions reports related to medicines and health products in children was carried out for a six-year period (2008-2013). Year of report, origin of report by Brazilian state, gender, age, suspected drug, adverse reaction description and seriousness were included in the analysis. The data obtained was compared to the number of pediatric beds in health services and to global data from the VigiBase (World Health Organization). Results: A total of 3330 adverse drug reactions were reported in children in Brazil in the investigated period (54% were in boys). About 28% of suspected adverse drug reactions reports involved 0 to 1-year-old children. Almost 40% of reports came from the Southeast region. Approximately 60% were classified as serious events. There was death in 75 cases. Nearly 30% of deaths involved off-label use; 3875 medicines (465 active substances) were considered suspected drugs. Anti-infective (vancomycin, ceftriaxone, oxacillin, and amphotericin), nervous system (metamizole) and alimentary tract and metabolism medicines were more frequent in reports. Conclusions: The distribution of suspected adverse drug reactions reports by sex and age group corresponded to the profile of children hospitalized in Brazil. Data about seriousness and medicines reported may be useful to encourage regulatory actions and improve the safe use of medicines in children.

RESUMO Objetivo: Analisar relatos espontâneos de suspeitas de Reação Adversa a Medicamento (RAM) em crianças de 0 a 12 anos notificadas pela Agência Nacional de Vigilância Sanitária entre 2008 e 2013. Métodos: Um estudo transversal a partir de notificações de suspeitas de RAM relacionadas a medicamentos e produtos para a saúde em crianças foi realizado por um período de seis anos (2008-2013). O ano da notificação, a origem do relato por estado brasileiro, sexo, idade, o medicamento suspeito, a descrição da reação adversa e a gravidade foram incluídos na análise, bem como o número de leitos nos serviços de saúde e dados global da VigiBase. Resultados: Um total de 3330 reações adversas foram relatadas em crianças no Brasil no período investigado (54% em meninos). Cerca de 28% dos relatos de suspeitas de RAM envolveram crianças de 0 a 1 ano de idade. Quase 40% dos relatos vieram da região Sudeste. Aproximadamente 60% foram classificados como eventos graves. Houve ocorrência de morte em 75 casos. Quase 30% das mortes envolveram o uso off-label dos medicamentos. Um total de 3875 medicamentos (465 substâncias ativas) foram considerados fármacos suspeitos. Medicamentos anti-infecciosos (vancomicina, ceftriaxona, oxacilina e anfotericina), com ação no sistema nervoso (dipirona) e no trato digestivo foram os mais frequentemente notificados. Conclusões: As notificações de suspeitas de RAM por sexo e faixa etária corresponderam ao perfil de crianças hospitalizadas no Brasil. Os dados sobre gravidade e medicamentos relatados podem ser úteis para encorajar ações reguladoras e melhorar o uso seguro de medicamentos em crianças.

rhIGF-1/rhIGFBP-3 in Preterm Infants: A Phase 2 Randomized Controlled Trial.

OBJECTIVE: To investigate recombinant human insulin-like growth factor 1 complexed with its binding protein (rhIGF-1/rhIGFBP-3) for the prevention of retinopathy of prematurity (ROP) and other complications of prematurity among extremely preterm infants. STUDY DESIGN: This phase 2 trial was conducted from September 2014 to March 2016. Infants born at a gestational age of 230/7 weeks to 276/7 weeks were randomly allocated to rhIGF-1/rhIGFBP-3 (250 µg/kg/ 24 hours, continuous intravenous infusion from <24 hours of birth to postmenstrual age 296/7 weeks) or standard neonatal care, with follow-up to a postmenstrual age of 404/7 weeks. Target exposure was ≥70% IGF-1 measurements within 28-109 µg/L and ≥70% intended therapy duration. The primary endpoint was maximum severity of ROP. Secondary endpoints included time to discharge from neonatal care, bronchopulmonary dysplasia, intraventricular hemorrhage, and growth measures. RESULTS: Overall, 61 infants were allocated to rhIGF-1/rhIGFBP-3, 60 to standard care (full analysis set); 24 of 61 treated infants achieved target exposure (evaluable set). rhIGF-1/rhIGFBP-3 did not decrease ROP severity or ROP occurrence. There was, however, a 53% decrease in severe bronchopulmonary dysplasia in the full analysis set (21.3% treated vs 44.9% standard care), and an 89% decrease in the evaluable set (4.8% vs 44.9%; P = .04 and P = .02, respectively) for severity distribution between groups. There was also a nonsignificant trend toward decrease in grades 3-4 intraventricular hemorrhage in the full analysis set (13.1% vs 23.3%) and in the evaluable set (8.3% vs 23.3%). Fatal serious adverse events were reported in 19.7% of treated infants (12/61) and 11.7% of control infants (7/60). No effect was observed on time to discharge from neonatal care/growth measures. CONCLUSIONS: rhIGF-1/rhIGFBP-3 did not affect development of ROP, but decreased the occurrence of severe bronchopulmonary dysplasia, with a nonsignificant decrease in grades 3-4 intraventricular hemorrhage. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01096784.

Toxic excipients in medications for neonates in Brazil.

UNLABELLED: The aim was to describe the exposure to excipients among neonates hospitalised in the neonatal intensive care unit (NICU) of a public hospital in Brasilia, Brazil. This was a retrospective study based on medicines that were prescribed electronically to neonates (≤28 days) who were admitted to the NICU of a hospital in Brasilia between January 1 and March 31, 2012. Excipients were identified from the medicine package leaflets and were classified according to toxicity. Seventy-nine infants received a total of 1,303 prescriptions comprising 77 formulations and 70 active drugs. Eighty-six excipients were identified, of which, 9 were harmful excipients (HE) and 48 were potentially harmful excipients (PHE). Almost all the neonates (98.7 %) were exposed to at least one HE and PHE. Preterm neonates (n = 64; 1,502 neonate days) presented high risk of exposure to polysorbate 80 (3.26/100 neonate days), sodium hydroxide (3.39), PG (3.19) and propylparaben (3.06). Full-term neonates (n = 15; 289 neonate days) presented risks in relation to phenol (4.84), ethanol (3.8) and sodium citrate (3.46). CONCLUSION: Neonates in NICUs in Brazil are exposed to a wide variety of HE and PHE with unpredictable results. Safer alternatives are needed, as well as further studies on the subject.
