OBJECTIVES: There have been few clinical trials (CTs) on antibiotics that inform neonatal and paediatric drug labelling. The rate of unlicensed and off-label prescribing in paediatrics remains high. It is unclear whether the current neonatal and paediatric antibiotic research pipeline is adequate to inform optimal drug dosing. Using the ClinicalTrials.gov registry, this review aims to establish the current global status of antibiotic CTs in children up to 18 years of age. METHODS: Studies were identified using key word searches of the ClinicalTrials...

Background: The increase in antibiotic resistance in Gram-negative bacteria and the limited therapeutic options due to the shortage of new antibiotics have increased the interest of the 'old' antibiotic fosfomycin in the treatment of infections. However, there are contradictory reports on the pharmacodynamics of and emergence of resistance to fosfomycin. Methods: Time-kill assays were performed with 11 ESBL-positive and 3 ESBL-negative strains, exposing the bacteria to 2-fold static concentrations from 0...

Infections account for significant morbidity and mortality in liver cirrhosis and most are related to the gut microbiome. Fecal dysbiosis, characterized by an overgrowth of potentially pathogenic bacteria and a decrease in autochthonous non-pathogenic bacteria, becomes prominent with the progression of liver cirrhosis. In cirrhotic patients, disruption of the intestinal barrier causes intestinal hyperpermeability (i.e. leaky gut), which is closely related to gut dysmotility, dysbiosis and small intestinal bacterial overgrowth and may induce pathological bacterial translocation...

In September 2011, a total of 511 human cases of anthrax (Bacillus anthracis) infection and 5 deaths were reported in a game management area in the district of Chama, Zambia, near where 85 hippopotamuses (Hippopotamus amphibious) had recently died of suspected anthrax. The human infections generally responded to antibiotics. To clarify transmission, we conducted a cross-sectional, interviewer-administered household survey in villages where human anthrax cases and hippopotamuses deaths were reported. Among 284 respondents, 84% ate hippopotamus meat before the outbreak...

BACKGROUND: Rural residents have poorer oral health and more limited access to dental services than their city counterparts. In rural communities, health care professionals often work in an extended capacity due to the needs of the community and health workforce shortages in these areas. Improved links and greater collaboration between resident rural primary care and dental practitioners could help improve oral health service provision such that interventions are both timely, effective and lead to appropriate follow-up and referral...

Reclaimed water has emerged as a potential irrigation solution to freshwater shortages. However, limited data exist on the persistence of antibiotics in reclaimed water used for irrigation. Therefore, we examined the fate of nine commonly-used antibiotics (ampicillin, azithromycin, ciprofloxacin, linezolid, oxacillin, oxolinic acid, penicillin G, pipemidic acid, and tetracycline) in differentially treated wastewater and reclaimed water from two U.S. regions. We collected 72 samples from two Mid-Atlantic and two Midwest treatment plants, as well as one Mid-Atlantic spray irrigation site...

Background: Anti-infective shortages are a pervasive problem in the United States. The objective of this study was to identify any associations between changes in prescribing of antibiotics that have a high risk for CDI during a piperacillin/tazobactam (PIP/TAZO) shortage and hospital-onset Clostridium difficile infection (HO-CDI) risk in 88 US medical centers. Methods: We analyzed electronically captured microbiology and antibiotic use data from a network of US hospitals from July 2014 through June 2016...

BACKGROUND: Antibiotic resistance is a global public health crisis. In India alone, multi-drug resistant organisms are responsible for over 58,000 infant deaths each year. A major driver of drug resistance is antibiotic misuse, which is a pervasive phenomenon worldwide. Due to a shortage of trained doctors, access to licensed allopathic doctors is limited in India's villages. Pharmacists and unlicensed medical providers are commonly the primary sources of healthcare. Patients themselves are also key participants in the decision to treat an illness with antibiotics...

With an established role in cystic fibrosis and bronchiectasis, nebulized antibiotics are increasingly being used to treat respiratory infections in critically ill invasively mechanically ventilated adult patients. Although there is limited evidence describing their efficacy and safety, in an era when there is a need for new strategies to enhance antibiotic effectiveness because of a shortage of new agents and increases in antibiotic resistance, the potential of nebulization of antibiotics to optimize therapy is considered of high interest, particularly in patients infected with multidrug-resistant pathogens...

The predicted shortage in new antibiotics has prompted research for chemicals that could act as adjuvant and enhance efficacy of available antibiotics. In this study, we tested the effects of combining metals with aminoglycosides on Escherichia coli survival. The best synergizing combination resulted from mixing aminoglycosides with silver. Using genetic and aminoglycoside uptake assays, we showed that silver potentiates aminoglycoside action in by-passing the PMF-dependent step, but depended upon protein translation...

The objective of this meta-analysis was to assess the efficacy of the treatment of bovine metritis with common antibiotic and nonantibiotic treatment options. Acute puerperal metritis, a systemic and potentially painful illness with rectal temperature >39.5°C and signs of toxemia due to an infection of the uterus, occurs within 21 d after parturition. Because of the infectious nature, antibiotics are considered beneficial for the treatment of acute puerperal metritis. Each use of an antimicrobial drug, however, is associated with selective pressure for eventual emergence of resistant bacteria...

Background: There is real shortage of national data on antimicrobial resistance rates in Indian neonates and children. A descriptive review was conducted to determine the patterns of antimicrobial resistance in isolates of blood stream infection among hospitalized children in India. Methods: Published and gray literature on antibiotic resistance in children was searched using "Google Scholar", "Scopus", and "PubMed" databases between January 2000 and July 2015. Studies were included if they were original articles that reported a minimum of 10 pathogenic bacterial isolates from the bloodstream within a pediatric population in India, and studies were excluded if they reported studies done during an outbreak or epidemic...

Millions of patients are evaluated every year in the emergency department (ED) for bacterial infections. Emergency physicians often diagnose and prescribe initial antibiotic therapy for a variety of bacterial infections, ranging from simple urinary tract infections to severe sepsis. In life-threatening infections, inappropriate choice of initial antibiotic has been shown to increase morbidity and mortality. As such, initiation of appropriate antibiotic therapy on the part of the emergency physician is critical...

The emergence of multiresistant bacteria worldwide together with the shortage of effective antibiotics in the market emphasizes the need for the design and development of the promising agents for the treatment of superbug-associated infections. Antimicrobial peptides (AMPs) have been considered as excellent candidates to tackle this issue, and thousands of peptides of different lengths, amino acid compositions, and mode of action have been discovered and prepared to date. Nevertheless, it is of great importance to develop innovative formulation strategies for delivering these AMPs and to improve their low bioavailability and metabolic stability, particularly against proteases, if these peptides are to find applications in the clinic and administered orally or parenterally or used as dietary supplements...

We present the first description of an antimicrobial stewardship program (ASP) used to successfully manage a multi-antimicrobial drug shortage. Without resorting to formulary restriction, meropenem utilization decreased by 69% and piperacillin-tazobactam by 73%. During the shortage period, hospital mortality decreased (P=.03), while hospital length of stay remained unchanged. Infect Control Hosp Epidemiol 2017;38:356-359.

The development and rapid dissemination of antibiotic-resistant bacterial pathogens has tarnished the dream of a world without infectious diseases. However, our understanding of these processes, paired with sequence information from terrestrial bacterial populations, indicates that there is no shortage of novel natural products that could be developed into new medicines. Regardless, their therapeutic success in the clinic will depend on the introduction of mandatory controls and use restrictions.
