Abstract
Objective. Children's vulnerability to drug-related side effects has been highlighted in several studies. However, there is no consensus on the risk factors associated with these side effects. This study aimed to investigate risk factors associated with drug-related side effects in children. Methods. This scoping review was conducted across multiple databases. The search strategy was created with a focus on drug-related side effects, as they are more predictable based on the pre-determined risk factors. Data were collected, and reported narratively. Results. The demographic, health, hospital, and drug-related risk factors may cause drug-related side effects in children. Among them, low age, sex, polypharmacy, length of hospitalization, and medications used for comorbidities may increase the risk. Conclusion. While most of the risk factors might be similar in adults and children, their impact might be different in these 2 groups. Therefore, future studies should identify more details about the impact of the risk factors in children.

Ital J Pediatr 2024; 50:127. [PMID: 39010141 PMCID: PMC11247891 DOI: 10.1186/s13052-024-01694-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2024] [Accepted: 06/25/2024] [Indexed: 07/17/2024] Open
Abstract
Drug hypersensitivity reactions are common in children. Risk factors predisposing to IgE-mediated drug allergies and delayed drug reactions are a matter of debate. Gender, age, previous reactions to the same drug or to another drug, reduced drug metabolism, chronic diseases, polypharmacy, drug doses are linked with the onset of hypersensitivity reactions in some children. Novel advances in genetic polymorphisms can rapidly change the approach to the prevention of reactions since gene testing can be a useful screening test for severe cutaneous adverse reactions. Viral infections may act as cofactors in susceptible individuals. Polypharmacy, high doses, repeated doses and parental route of administration are also risk factors. Clinicians should take into account risk factors to allow the risk-benefit balance to be maintained.

Adverse drug reactions in paediatric surgery: prospective study on frequency and risk related factors. BMC Pediatr 2024; 24:344. [PMID: 38760745 PMCID: PMC11102197 DOI: 10.1186/s12887-024-04803-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Accepted: 05/02/2024] [Indexed: 05/19/2024] Open
Abstract
BACKGROUND Paediatric patients are especially prone to experiencing adverse drug reactions (ADRs), and the surgical environment gathers many conditions for such reactions to occur. Additionally, little information exists in the literature on ADRs in the paediatric surgical population. We aimed to quantify the ADR frequency in this population, and to investigate the characteristics and risk factors associated with ADR development. METHODS A prospective observational study was conducted in a cohort of 311 paediatric patients, aged 1-16 years, admitted for surgery at a tertiary referral hospital in Spain (2019-2021). Incidence rates were used to assess ADR frequency. Odds ratios (ORs) were calculated to evaluate the influence of potential risk factors on ADR development. RESULTS Distinct ADRs (103) were detected in 80 patients (25.7%). The most frequent being hypotension (N = 32; 35%), nausea (N = 16; 15.5%), and emergence delirium (N = 16; 15.5%). Most ADRs occurred because of drug-drug interactions. The combination of sevoflurane and fentanyl was responsible for most of these events (N = 32; 31.1%). The variable most robustly associated to ADR development, was the number of off-label drugs prescribed per patient (OR = 2.99; 95% CI 1.73 to 5.16), followed by the number of drugs prescribed per patient (OR = 1.26, 95% CI 1.13 to 1.41), and older age (OR = 1.26, 95% CI 1.07 to 1.49). The severity of ADRs was assessed according to the criteria of Venulet and the Spanish Pharmacovigilance System. According to both methods, only four ADRs (3.9%) were considered serious. CONCLUSIONS ADRs have a high incidence rate in the paediatric surgical population. The off-label use of drugs is a key risk factor for ADRs development.

Abstract
BACKGROUND Post-marketing surveillance of drugs is a cornerstone of pharmacovigilance. This study was conducted to characterize patterns of adverse drug reactions (ADRs) reported in Jordan. RESEARCH DESIGN AND METHODS ADR reports submitted to the pharmacovigilance database of the Jordan Food and Drug Administration during 2015-2021 were retrospectively analyzed. The most commonly reported drugs, drug classes, ADRs, and ADRs consequences were explored. Logistic regression identified possible predictors of reporting serious ADRs. RESULTS A total of 2744 ADR reports were included, among which 28.4% were classified as serious. An annual increase in ADR reporting was observed. The most commonly implicated drug classes were antineoplastic and immunomodulating agents (24.0%), anti-infectives for systemic use (14.2%), and alimentary tract and metabolism (12.1%). Covid-19 vaccination was the most reported drug (22.8%). Fatigue (6.3%), injection site pain (6.1%), and headache (6.0%) were the top three common ADRs. Among ADRs with outcome information, 4.7% were fatal. Patient's age and intravenous medication use largely predicted reporting serious ADRs. CONCLUSIONS This study provides contemporary insights into the post-marketing surveillance of drugs in Jordan. The findings are foundational for future studies exploring drug-ADRs causality relationships. Efforts that promote pharmacovigilance concepts should be sustained and enhanced at the national level.

Abstract
Introduction Highly active antiretroviral therapy (HAART) is used to treat human immunodeficiency virus type 1 (HIV-1). Introduction of antiretroviral therapy (ART) has reduced the HIV/AIDS associated morbidity and mortality significantly. But 25% of all patients discontinue treatment because of adverse drug reactions (ADRs). Adverse cutaneous drug reactions (ACDR) are very common with ART regimens, which may range from mild pruritus, maculopapular rash to serious Steven Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN). ACDRs comprise 10%-30% of all reported ADRs. Aims and Objectives To assess the different types of cutaneous adverse drug reactions in immunocompromised children of less than 18years. Materials and Methods This is a retrospective record-based study, conducted at department of Dermatology, Venereology and Leprosy, Government Medical College (GMC)/Government General Hospital (GGH), Suryapet, Telangana, India. Data was collected from the records available at ART centre, from November 2018 to October 2021 GGH, Suryapet. All the HIV infected children ≤18 years who were on ART, were included in this study. Patients of more than 18 years and on other medications were excluded. Demographic data, socio economic status, vaccination status, height, weight, complete blood analysis, complete urine analysis, erythrocyte sedimentation rate, liver and renal function tests and CD4 counts were recorded before initiation of ART. Results A total of 330 children of less than 18 years were initiated for ART, at ART centre, Government General Hospital, Suraypet. Out of 330 children, 27.8% (92) children developed ACDRs. 58.7% (54) were males and 41.3% (38) were females. Maculopapular rash was seen in 65.2% (60) cases, urticaria was seen in 15.3% (14) cases, Steven Johnson Syndrome (SJS) was seen in 9.8% (9) cases, SJS/TEN overlap was seen in 6.5% (6) cases and toxic epidermal necrolysis (TEN) was seen in 3.2% (3) case. CD4 count was below 300 in 65.3% (60) cases above 300 in 34.7% (32) cases. Gap between initiation of the treatment and onset of reaction was less than one month in 65.3% (60) cases, and more than one month in 34.7% (32) cases.

Abstract
We report three preterm infants who were treated with paracetamol for hemodynamically significant patent ductus arteriosus and developed acute hemolysis. No other apparent cause of acute hemolysis was found during Neonatal Intensive Care Unit hospitalization. All three infants were born within 1 year. As this side effect of paracetamol has not been reported previously and many preterm infants receive paracetamol for PDA closure, we advocate awareness. We cannot be sure whether the hemolysis occurred due to an underlying cause that was augmented by paracetamol or whether the drug itself caused acute hemolysis in these preterm infants.

Abstract
BACKGROUND AND OBJECTIVE More than half of all drugs are still prescribed off-label to children. Pharmacokinetic (PK) data are needed to support off-label dosing, however for many drugs such data are either sparse or not representative. Physiologically-based pharmacokinetic (PBPK) models are increasingly used to study PK and guide dosing decisions. Building compound models to study PK requires expertise and is time-consuming. Therefore, in this paper, we studied the feasibility of predicting pediatric exposure by pragmatically combining existing compound models, developed e.g. for studies in adults, with a pediatric and preterm physiology model. METHODS Seven drugs, with various PK characteristics, were selected (meropenem, ceftazidime, azithromycin, propofol, midazolam, lorazepam, and caffeine) as a proof of concept. Simcyp® v20 was used to predict exposure in adults, children, and (pre)term neonates, by combining an existing compound model with relevant virtual physiology models. Predictive performance was evaluated by calculating the ratios of predicted-to-observed PK parameter values (0.5- to 2-fold acceptance range) and by visual predictive checks with prediction error values. RESULTS Overall, model predicted PK in infants, children and adolescents capture clinical data. Confidence in PBPK model performance was therefore considered high. Predictive performance tends to decrease when predicting PK in the (pre)term neonatal population. CONCLUSION Pragmatic PBPK modeling in pediatrics, based on compound models verified with adult data, is feasible. A thorough understanding of the model assumptions and limitations is required, before model-informed doses can be recommended for clinical use.

Abstract
Advances in cancer molecular profiling have enabled the development of more effective approaches to the diagnosis and personalized treatment of tumors. However, treatment planning has become more labor intensive, requiring hours or even days of clinician effort to optimize an individual patient case in a trial-and-error manner. Lessons learned from the world cancer programs provide insights into ways to develop approaches for the treatment strategy definition which can be introduced into clinical practice. This article highlights the variety of breakthroughs in patients' cancer treatment and some challenges that this field faces now in Russia. In this report, we consider the key characteristics for planning an optimal clinical treatment regimen and which should be included in the algorithm of clinical decision support systems. We discuss the perspectives of implementing artificial intelligence-based systems in cancer treatment planning in Russia.

Abstract
IMPORTANCE Pharmacogenomic (PGx) testing provides preemptive pharmacotherapeutic guidance regarding the lack of therapeutic benefit or adverse drug reactions of PGx targeted drugs. Pharmacogenomic information is of particular value among children with complex medical conditions who receive multiple medications and are at higher risk of developing adverse drug reactions. OBJECTIVES To assess the implementation outcomes of a PGx testing program comprising both a point-of-care model that examined targeted drugs and a preemptive model informed by whole-genome sequencing that evaluated a broad range of drugs for potential therapy among children in a pediatric tertiary care setting. DESIGN, SETTING, AND PARTICIPANTS This cohort study was conducted at The Hospital for Sick Children in Toronto, Ontario, from January 2017 to September 2020. Pharmacogenomic analyses were performed among 172 children who were categorized into 2 groups: a point-of-care cohort and a preemptive cohort. The point-of-care cohort comprised 57 patients referred to the consultation clinic for planned therapy with PGx targeted drugs and/or for adverse drug reactions, including lack of therapeutic benefit, after the receipt of current or past medications. The preemptive cohort comprised 115 patients who received exploratory whole-genome sequencing-guided PGx testing for their heart conditions from the cardiac genome clinic at the Ted Rogers Centre for Heart Research. EXPOSURES Patients received PGx analysis of whole-genome sequencing data and/or multiplex genotyping of 6 pharmacogenes (CYP2C19, CYP2C9, CYP2D6, CYP3A5, VKORC1, and TPMT) that have established PGx clinical guidelines. MAIN OUTCOMES AND MEASURES The number of patients for whom PGx test results warranted deviation from standard dosing regimens. RESULTS A total of 172 children (mean [SD] age, 8.5 [5.6] years; 108 boys [62.8%]) were enrolled in the study. In the point-of-care cohort, a median of 2 target genes (range, 1-5 genes) were investigated per individual, with CYP2C19 being the most frequently examined; genotypes in 21 of 57 children (36.8%) were incompatible with standard treatment regimens. As expected from population allelic frequencies, among the 115 children in the whole-genome sequencing-guided preemptive cohort, 92 children (80.0%) were recommended to receive nonstandard treatment regimens for potential drug therapies based on their 6-gene pharmacogenetic profile. CONCLUSIONS AND RELEVANCE In this cohort study, among both the point-of-care and preemptive cohorts, the multiplex PGx testing program provided dosing recommendations that deviated from standard regimens at an overall rate that was similar to the population frequencies of relevant variants.

Causality and avoidability of adverse drug reactions of antibiotics in hospitalized children: a cohort study. Int J Clin Pharm 2021; 43:1293-1301. [PMID: 33656658 DOI: 10.1007/s11096-021-01249-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2020] [Accepted: 02/12/2021] [Indexed: 10/22/2022]
Abstract
BACKGROUND Adverse drug reactions are a problem in healthcare systems worldwide. Children are more susceptible than adults, especially when exposed to specific drug classes, such as antibiotics. OBJECTIVE To assess the incidence, causality, severity, and avoidability of antibiotic-associated adverse drug reactions in hospitalized pediatric patients. SETTING Pediatric ward of a high-complexity public hospital in northeast Brazil. METHODS A prospective cohort study was conducted over six months, including children aged between 28 days and 12 years, hospitalized for more than 48 h, and receiving antibiotics. Liverpool's causality and avoidability assessment tools were used. Primary outcome measures: Incidence of adverse drug reactions, causality, severity, and avoidability, major antibiotics implicated, risk factors. RESULTS A total of 183 patients were followed, and 35 suspected adverse drug reactions were recorded overall incidence equal to 14.7%. Most adverse drug reactions were classified as moderate severity (76.7%), probable (57.1%) and defined (28.6%) causality, and unavoidable (66.7%). The affected organs were the gastrointestinal system (74.1%) and skin (25.9%). Major antibiotics implicated were ceftriaxone (40.7%), azithromycin (25.9%), and crystalline penicillin (11.1%). The number of antibiotics prescribed per patient during hospitalization and the length of stay were the risk factors identified. CONCLUSION Causality and severity assessment indicated that most adverse drug reactions were probable and moderate. Possibly avoidable reactions occurred due to inappropriate prescribing when preventive measures were not implemented. Monitoring the use of antibiotics in children is essential to ensure the safety of these patients.

Abstract
The relationship between the Naranjo scaling system and pediatric adverse drug reactions (ADR) is poorly understood. We performed a retrospective review of 1,676 pediatric ADRs documented at our hospital from 2014–2018. We evaluated patient demographics, implicated medication, ADR severity, calculated Naranjo score, associated symptoms, and location within the hospital in which the ADR was documented. ADR severity was poorly correlated with Naranjo interpretation. Out of the 10 Naranjo scale questions, 4 had a response of “unknown” greater than 85% of the time. Cardiovascular and oncological/immunologic agents were more likely to have a probable or definite Naranjo interpretation compared to antimicrobials. Further strategies are needed to enhance the causality assessment of pediatric ADRs in clinical care.

Abstract
The drug allergy "label" may have a lifetime of consequences for a child. Many children with alleged drug allergies are proven to be tolerant to the culprit medication when challenged. The field of drug hypersensitivity is a recently evolving field of research, but studies on its epidemiology and diagnostic tools are lacking in children. Clinical history is significant in the diagnosis and classification of drug hypersensitivity in children. Diagnostic tools have been evaluated in a limited number of children; therefore, the guidelines are mainly in line with those for adults. Here, we review the clinical characteristics, main drugs, risk factors, and diagnosis of drug hypersensitivity to aid in its accurate diagnosis in children.

Abstract
Background and Objectives: Over-the-counter (OTC) medication use has increased safety risks for adults older than 65. Most older adults purchase OTC medications from community pharmacies, where the considerable distance or visual obstructions between the prescription area and OTC aisles undermine pharmacists’ ability to assist patients with OTC medication decisions. An innovative redesign of an abbreviated medication section specifically for older adults (called the Senior SectionTM ) can facilitate pharmacy staff/patient interaction, potentially improving safe medication selection and use. This study evaluated the impact of the Senior Section on the frequency and content of OTC encounters between pharmacy staff and patients. Research Design and Methods: An intervention mixed-methods design generated data from patient OTC encounters, and interviews with two pharmacists and two technicians, throughout the study. NVivo was used to code interview transcripts, and frequencies and chi-square analyses demonstrated pre/post-intervention comparisons for the OTC encounter variables. Results: After Senior Section implementation, pharmacy staff were more likely to initiate (and be involved in) patient encounters, address more topics or problem/symptoms, provide details about OTC products, discuss appropriateness of OTC use, and discuss medication classes highlighted in the Senior Section. Pharmacy staff were less likely to need to leave the prescription department for extended periods; they also had fewer prolonged encounters or encounters about product location. Importantly, the Senior Section did not impede pharmacy workflow. Discussion and Implications: The Senior Section prompted more frequent, effective, and efficient engagements between pharmacy staff and patients, which may substantially reduce OTC-related harms among older adults.
