Abstract
Background and objective The incidence of adverse drug reactions (ADRs) in hospitalized children varies from 0.6-16.8%. There is a lack of uniformity and an absence of quality reporting with respect to the collection of data on ADRs worldwide, resulting in a scarcity of data regarding ADRs in children. In light of this, we aimed to analyze various factors related to ADRs in the pediatric population in the ADR Monitoring Center (AMC) of a teaching hospital in Odisha, India. Methods This was a record-based study conducted by the department of pharmacology in collaboration with the department of pediatrics. Detailed information regarding all ADR cases in children (<14 years of age) was collected in a format designed by the Indian Pharmacopoeia Commission (IPC). A total of 105 ADRs reported during a five-year period (2015-20) were subjected to analysis. Results The largest number of ADRs were reported in the age group zero to five years (41%). Males were affected more compared to females (1.7:1). Cutaneous ADRs were the most common type (86.5%) followed by the involvement of the gastrointestinal system (10%); 21% of cases were serious in nature, i.e., they required either hospitalization or led to a prolonged hospital stay. Antibiotics were the major drug category involved in causing drug reactions (66%) and among them, ceftriaxone (24.6%) was the most common causative agent. Conclusions One-fifth of the pediatric cases of ADRs were serious in nature. The most common causative agent was antibiotics, especially beta-lactams. There is an urgent need to raise awareness among healthcare professionals by conducting training programs to encourage the spontaneous reporting of ADRs, which will help to ensure drug safety in the pediatric population.

Abstract
BACKGROUND The high incidence of adverse drug reactions (ADRs) in children is of global concern. Enhancing the reporting of ADRs could contribute to making safer medicines available to children. AIM To assess parents' awareness of reporting ADRs and their knowledge on the reporting procedures in South Africa. SETTING South African parents with online access. METHOD A quantitative descriptive study was conducted based on an anonymous voluntarily web-based self-administered questionnaire that was distributed through Facebook® and LinkedIn™ to parents in South Africa. RESULTS The questionnaire was completed voluntarily by 206 respondents. The majority of participants (70.9%) were aware of the term ADR. Significant associations between not being aware of the term ADR and single marital status, lower education level, not having private medical aid and accessing public clinics for medical services were found. The majority (66.5%) of participants did report an ADR to a healthcare professional whilst only 15% reported it to a product manufacturer. More than half of the participants (58.7%) knew how to report ADRs whilst 72.8% knew what type of ADRs to report. Almost a third (32.5%) did not know where more information on ADR reporting could be found or how ADRs could be reported (31.5%). CONCLUSION The majority of the respondents were aware of the term ADR, indicative of a good knowledge basis on which ADRs to report and the importance of reporting ADRs. However, gaps in the respondents' knowledge were identified which highlighted specific groups of individuals to be targeted to increase ADR awareness and improve the knowledge on the reporting process.

Abstract
Background WHO pharmacovigilance indicators have been recommended as a useful tool towards improving pharmacovigilance activities. Nigeria with a myriad of medicines related issues is encouraging the growth of pharmacovigilance at peripheral centres. This study evaluated the status of pharmacovigilance in tertiary hospitals in the South-South zone of Nigeria with a view towards improving the pharmacovigilance system in the zone. Methods A cross-sectional descriptive survey was conducted in six randomly selected tertiary hospitals in the South-South zone of the country. The data was collected using the WHO core pharmacovigilance indicators. The language of assessment was phrased and adapted in this study for use in a tertiary hospital setting. Data is presented quantitatively and qualitatively. Results A total of six hospitals were visited and all institutions had a pharmacovigilance centre, only three could however be described as functional or partially functional. Only one centre had a financial provision for pharmacovigilance activities. Of note was the absence of the national adverse drug reaction reporting form in one of the hospitals. The number of adverse drug reaction reports found in the databases of the centres ranged from none to 26 for the previous year and only one centre had fully committed their reports to the National Pharmacovigilance Centre. There were few documented medicines related admissions ranging from 0.0985/1000 to 1.67/1000 and poor documentation of pharmacovigilance activities characterised all centres. Conclusion This study has shown an urgent need to strengthen the pharmacovigilance systems in the South-South zone of Nigeria. Improvement in medical record documentation as well as increased institutionalization of pharmacovigilance may be the first steps to improve pharmacovigilance activities in the tertiary hospitals.

Abstract
BACKGROUND Adverse drug reactions (ADRs) in children recorded in national pharmacovigilance databases in high-income countries have been analysed. Nigeria has a population of 31 million children and became a member of the WHO Programme for International Drug Monitoring in 2004 since when it has been submitting reports of suspected ADRs to the WHO Global Individual Case Safety Report database, VigiBase. OBJECTIVE To gain information on reported ADRs in Nigerian children aged 0-17 years in VigiBase from 2005 to 2012. METHODS The data were analysed for annual reports, age and sex of patients, type of reporters, suspected drugs and adverse reactions. The most commonly reported ADRs and suspected drugs were ranked, and drugs associated with the fatalities were evaluated. RESULTS A total of 297 reports of 473 ADRs in 297 children were received from doctors, pharmacists, other health-care professionals and consumers during the period. ADRs were most frequently reported for anti-retrovirals (74, 24%), antibiotics (71, 23%) and anti-malarials (60, 20%). The most frequently reported ADRs were rash (15.2%), fever (10.3%) and pruritus (6.8%). Anti-infective agents were responsible for more than half of the reports. Twenty-one children (7%) died, eight from acute renal failure. Seven of the cases of acute renal failure were associated with contaminated paracetamol/diphenhydramine hydrochloride and herbal medicines used for teething problems. In the majority of cases, the products were contaminated with diethylene glycol. There were 14 cases of Stevens-Johnson syndrome, three of which were fatal. CONCLUSION Anti-infective agents (antibiotics, anti-malarials and anti-retrovirals) were associated with a majority of the ADRs. Stevens-Johnson syndrome was the most frequent severe ADR. Some of the fatalities were associated with sub-standard and herbal medications.

Abstract
PURPOSE Drug-related problems (DRPs) are common in paediatric pharmacotherapy, but few studies describe them from the parents' perspective. In the present survey, we have investigated the lifetime prevalence and type of DRPs in children in Finland. METHODS This was a population-based survey of a random sample of 6,000 children below 12 years of age in 2007. A questionnaire was sent to their parents. The final response rate was 67% with a study population of 4,032. The main outcome measure was the lifetime prevalence and type of DRPs. RESULTS The lifetime prevalence of DRPs was 21% (95% CI 20-22). The most common (82%) of the 1,346 reported DRPs were adverse drug events (ADEs). The prevalence of ADEs was 17% (95% CI 16-19), that of other DRPs 5.2% (95% CI 4.5-5.9). The prevalence of serious ADEs was 0.4% and that of unexpected ADEs was 0.8%. The most common system involved in the ADEs was the gastrointestinal tract, comprising 34% of the 1,106 ADEs. The most common of the 240 other DRPs were problems with the administration and dosing of medicine (86%). Overall, 64% of DRPs were related to anti-infectives. CONCLUSIONS One fifth of the Finnish children below 12 years of age had experienced DRPs. Appropriate counselling, including possible adverse drug reactions and dosing directions, is important for parents and children at both the prescribing and dispensing of medicines for paediatric patients. Reporting of any suspected serious or unexpected ADEs is an essential part of efficient pharmacovigilance in paediatrics.

Abstract
The wide-scale roll-out of artemisinin combination therapies (ACTs) for the treatment of malaria should be accompanied by continued surveillance of their safety. Post-marketing pharmacovigilance (PV) relies on adverse event (AE) reporting by clinicians, but as a large proportion of treatments are provided by non-clinicians in low-resource settings, the effectiveness of such PV systems is limited. To facilitate reporting, AE forms should be easily completed; however, most are challenging for lower-level health workers and non-clinicians to complete. Through participatory research, we sought to develop user-friendly AE report forms to capture information on events associated with ACTs. Following situation analysis, we undertook workshops with community medicine distributors and health workers in Jinja, Uganda, to develop a reporting form based on experiences and needs of users, and communication and visual perception principles. Participants gave feedback for revisions of subsequent versions. We then conducted 8 pretesting sessions with 77 potential end users to test and refine passive and active versions of the form. The development process resulted in a form that included a pictorial storyboard to communicate the rationale for the information needed and facilitate rapport between the reporter and the respondent, and a diary format to record the drug administration and event details in chronological relation to each other. Successive rounds of pretesting used qualitative and quantitative feedback to refine the form, with the final round showing over 80% of the form completed correctly by potential end users. We developed novel AE report forms that can be used by non-clinicians to capture pharmacovigilance data for anti-malarial drugs. The participatory approach was effective for developing forms that are intuitive for reporters, and motivating for respondents. The forms, or their key components, could be adapted for use in other low-literacy settings to improve quality and quantity of drug safety reports as new medicines are scaled-up.

Abstract
Aim: To study the adverse drug reaction (ADR) pattern in a pediatric population in a tertiary care hospital. Materials and Methods: An observational study was done in the department of pediatrics in a tertiary care hospital. The ADRs occurring in the inpatient wards and outpatient department of pediatrics were actively monitored. The collected reports were analyzed for ADR pattern, drug groups, demographic profile, causality, severity, and preventability of the ADR. Results: A total of 30 ADRs were documented during the mid period of 2009 among pediatric patients. Most of the ADRs (60%) occurred below the age of 1 year. Antibiotics comprised the major group of drugs causing ADRs (67%). Rashes and urticaria were the most common type of ADR (37%) followed by fever, anaphylactic shock, vomiting, chills, and rigors. A single case of death had been reported in the study period. There were more occurrences of ADRs with multiple drugs compared to single drug therapy. About 80% of the ADRs were of probable causality and 87% were of probable preventability. There were no mild reactions, with 77% of reactions being moderate and 23% of reactions being severe in the severity scale. Conclusions: ADRs occur more among infants and antibiotics were more commonly implicated. Most of the reactions were of moderate severity. This indicates the need for a rigid ADR monitoring among pediatric patients to ensure safety of drug therapy.

Abstract
CONTEXT AND OBJECTIVES Adverse drug reactions (ADRs) may cause prolonged hospital admissions with high treatment costs. The burden of ADRs in children has never been evaluated in Nigeria. The incidence of pediatric ADRs and the estimated cost of treatment over an 18-month period were determined in this study. DESIGN AND SETTING Prospective observational study on children admitted to the pediatric wards of the Lagos State University Teaching Hospital (LASUTH) in Nigeria, between July 2006 and December 2007. METHODS Each patient was assessed for ADRs throughout admission. Medical and non-medical costs to the hospital and patient were estimated for each ADR by reviewing the medical and pharmacy bills, medical charts and diagnostic request forms and by interviewing the parents. Cost estimates were performed in 2007 naira (Nigeria currency) from the perspectives of the hospital (government), service users (patients) and society (bearers of the total costs attributable to treating ADRs). The total estimated cost was expressed in 2007 United States dollars (USD). RESULTS Two thousand and four children were admitted during the study; 12 (0.6%) were admitted because of ADRs and 23 (1.2%) developed ADR(s) during admission. Forty ADRs were suspected in these 35 patients and involved 53 medicines. Antibiotics (50%) were the most suspected medicines. Approximately 1.83 million naira (USD 15,466.60) was expended to manage all the patients admitted due to ADRs. CONCLUSIONS Treating pediatric ADRs was very expensive. Pediatric drug use policies in Nigeria need to be reviewed so as to discourage self-medication, polypharmacy prescription and sales of prescription medicines without prescription.

Abstract
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT Drug safety in paediatric medication is a public health concern. According to previous studies, the incidence of adverse drug reactions (ADRs) varies greatly from 0.7% to 2.7% among paediatric outpatients and from 2.6% to 18.1% among paediatric inpatients. Little has been reported on the risks of drug use in the general child population. WHAT THIS STUDY ADDS Our study showed that the prevalence of perceived ADRs in Germany was 0.9% among non-institutionalized children in general and 1.7% among children who had used at least one medicine within the 7 days before the medical interview. Perceived ADRs in the general child population were clustered with gastrointestinal disorders and subcutaneous tissue disorders. They appeared to be mild and at the lower limits of the range reported in other studies. Health surveys covering the use of a diverse range of drugs might be suitable for computing ADR prevalence and for identifying risk factors among non-institutionalized children. They should be taken into account together with other pharmacovigilance systems. AIMS Little has been reported on the risks of drug use in the general child population. This study investigated perceived adverse drug reactions (ADRs) among non-institutionalized children in Germany. METHODS All medicines used in the last 7 days before the medical interview were recorded among the 17 450 children aged 0-17 years who participated in the 2003-06 German Health Interview and Examination Survey for Children and Adolescents (KiGGS). Perceived ADRs were reported by the children's parents and confirmed by trained medical professionals during the medical interview. RESULTS One hundred and fifty-seven medicines were involved in the occurrence of 198 perceived ADRs in 153 patients. This corresponded to 1.1% of total used drugs, 0.9% (95% confidence intervals 0.7, 1.1%) of all children, and 1.7% (1.4, 2.1%) of children treated with medications. About 40% of all perceived ADRs involved gastrointestinal disorders and 16% involved skin tissue disorders. Perceived ADRs were most frequently reported in relation to drugs acting on the nervous system (25.8%), followed by systemic anti-infectives (18.7%) and drugs acting on the respiratory system (16.2%). Risk factors for perceived ADRs included older age groups, polypharmacy (>or=2) and a poor health status. CONCLUSION Perceived ADRs in the general child population were clustered with gastrointestinal disorders and subcutaneous tissue disorders. They appeared to be mild and at the lower limits of the range reported in other studies. Health surveys covering the use of a diverse range of drugs might be suitable for computing ADR prevalence and identifying risk factors among non-institutionalized children. They should be taken into account together with other pharmacovigilance systems.
