BACKGROUND: There are very few options to treat multidrug-resistant bacterial infections in children. A major barrier is the duration and complexity of regulatory trials of new antibiotics. Extrapolation of safety data from adult trials could facilitate drug development for children. OBJECTIVE: We performed a systematic review on the safety of antibiotic clinical trials (CTs) in children (0-18 years) to evaluate the overall quality of safety trials conducted in children and to determine if age-specific adverse events (AEs) could be identified for specific antibiotic classes...

South Africa has been engaged in pharmacovigilance (PV) activities to assess the impact of adverse drug reactions on public safety and health for 40 years. Activities have evolved from passive regulatory reporting to encompass active surveillance systems. The HIV and AIDS and TB epidemics stimulated pharmacoepidemiological research into the risks associated with medicines used in the standardised regimens of mass treatment programmes. Specific safety concerns, supported by robust local cohort data, have prompted major changes to national and international treatment policies...

BACKGROUND/AREA OF UNCERTAINTY: Statins, which reduce cardiovascular risk in both primary and secondary prevention, are one of the most widely prescribed therapeutic classes in the world. Usually well-tolerated, statin-associated muscle symptoms are a well-known adverse effect. Fusidic acid (FA) is a bacteriostatic antibiotic of interest in the treatment of methicillin-resistant Staphylococcus aureus infections. Cases of rhabdomyolysis, sometimes fatal, have been reported after coprescription of FA and a statin...

BACKGROUND: Biosimilars have the potential to create competition, lower costs, and increase patient access to biological medications. However, biological medications are sensitive to their manufacturing processes and difficult to precisely characterize, leading to questions about substitution and interchangeability among products. METHODS: This article reviews the role of biosimilars in patient access to therapeutic antibodies. RESULTS: Although pathways for the approval of biosimilars have been developed, important issues remain unresolved...

Biological drugs like therapeutic antibodies are widely used for the treatment of various diseases like inflammatory disorders and cancer. A drawback of these novel treatments is the substantial proportion of patients experiencing adverse reactions such as loss-of-drug effect or hypersensitivity reactions. These reactions are associated with pre-existing and/or developing anti-drug antibodies. Especially IgE development is a risk factor for life-threatening systemic anaphylaxis. METHODS: In order to characterize the individual drug-specific serum IgE, an IgE cross-reactivity immune profiling (ICRIP) assay was developed...

REVIEW
Silvio Garattini, Vittorio Bertele'
Consideration of drug benefits and harms is asymmetric. Approval of drugs is mainly based on efficacy, while the assessment of their safety is left to post-marketing commitments or spontaneous reporting. Benefits are overestimated as a result of pharmaceutical companies' advertisements, the paucity of independent information, and the scant understanding of the effectiveness of medicines in real life. Polypharmacy in older adults-even during the last period of their life-reflects the tendency to assign priority to efficacy and overlook harms, although nobody knows what happens when three or more drugs are given chronically...

Udo Bonnet, Norbert Scherbaum
In the last ten years, the prescriptions of the gabapentinoids gabapentin and pregabalin increased largely also in Germany. Since several national and international pharmacovigilance-databases have warned for abuse liabilities and overdose fatalities in association with both gabapentinoids, which moreover, became to be sold on internet and black-markets, their addictive power has been subject to an ongoing clinical debate. As pre- and post-approval clinical trials did not reveal significant signs of dependence on gabapentin or pregabalin, we systematically searched in PubMed and Scopus for clinical studies and case reports being associated with abuse of and dependence on these drugs...

Jean-Luc Faillie
Case-non case studies belongs to the methods assessing drug safety by analyzing the disproportionality of notifications of adverse drug reactions in pharmacovigilance databases. Used for the first time in the 1980s, the last few decades have seen a significant increase in the use of this design. The principle of the case-non case study is to compare drug exposure in cases of a studied adverse reaction with that of cases of other reported adverse reactions and called "non cases". Results are presented in the form of a reporting odds ratio (ROR), the interpretation of which makes it possible to identify drug safety signals...

BACKGROUND AND AIMS: We assessed post-marketing safety of sodium-glucose co-transporter-2 inhibitors (SGLT2-Is) by analyzing adverse events (AEs) reported in international pharmacovigilance databases. METHODS AND RESULTS: Eudravigilance, WHO-Vigibase (as of Feb 25, 2017) and the FDA Adverse Event Reporting System (FAERS, from 2004 to 2016 second quarter) were queried to extract AEs recording SGLT2-Is as suspect. Disproportionality analyses (case/non-case method) were performed in FAERS by calculating the reporting odds ratios (RORs) from System Organ Classes (SOCs) to Preferred Terms (PTs) (precise clinical entities)...

It is important that systems are in place to ensure that appropriate and comprehensive records are kept for use of all medications. It is fundamental to an effective pharmacovigilance system that patient medical records contain sufficient information to identify which medication has been prescribed, when it was administered, and at what dose. The availability of biologics from multiple sponsors has raised questions by some health care providers about the ability of current pharmacovigilance systems to trace specific biologics...

INTRODUCTION: In view of the underdeclaration of adverse drug reactions (ADRs), there is a need for optimizing their reporting. To improve our declaration, a pharmacovigilance program was started in 2006 at our center and measures were progressively started (weekly patient rounds, monthly report, etc.). The objectives of the study were to describe and compare the annual average incidence of the ADRs coded by the medical archivists from 1 April 1989 to 31 March 2010 (period 1) and from 1 April 2010 to 31 March 2015 (period 2), to determine the therapeutic classes of drugs associated with ADRs according to age and determine the percentage of ADRs that are declared to Health Canada...
