Abstract

Objectives

Relebactam is a diazabicyclooctane non-β-lactam inhibitor of Ambler class A and C β-lactamases that is in clinical development in combination with imipenem/cilastatin. The current study evaluated the in vitro activity of imipenem/relebactam against 5447 isolates of Pseudomonas aeruginosasubmitted to the SMART global surveillance programme in 2015–17 by 67 clinical laboratories in 22 European countries.

Methods

MICs were determined using the CLSI broth microdilution reference method (Eleventh Edition: M07, 2018). Relebactam was tested at a fixed concentration of 4 mg/L in combination with doubling dilutions of imipenem. MICs were interpreted using EUCAST clinical breakpoints (version 8.1); imipenem breakpoints were applied to imipenem/relebactam.

Results

Rates of susceptibility to imipenem and imipenem/relebactam (MIC ≤4 mg/L) were 69.4% and 92.4%, respectively, for all isolates of P. aeruginosa. Over one-third of all isolates (34.9%, 1902/5447) were MDR; lower respiratory tract isolates (38.3%, 1327/3461) were more frequently MDR than were intraabdominal (28.5%, 355/1245) or urinary tract (29.7%, 212/714) isolates. Of all MDR isolates, 78.2% were susceptible to imipenem/relebactam, a rate that was 50–77 percentage points higher than the rate of susceptibility to imipenem or any other β-lactam tested; rates of susceptibility to imipenem/relebactam were similar for MDR isolates from lower respiratory tract (77.8% susceptible), intraabdominal (80.3%) and urinary tract (76.4%) infections. Overall, relebactam restored imipenem susceptibility to 75.2% (1254/1668) of imipenem-non-susceptible isolates of P. aeruginosa and to 69.6% (947/1361) of imipenem-non-susceptible isolates with an MDR phenotype.

Conclusions

Relebactam restored in vitro susceptibility to imipenem for most imipenem-non-susceptible and MDR clinical isolates of P. aeruginosa from European patients.

Abstract

In Europe in 1918, influenza spread through Spain, France, Great Britain and Italy, causing havoc with military operations during the First World War. The influenza pandemic of 1918 killed more than 50 million people worldwide. In addition, its socioeconomic consequences were huge. “Spanish flu”, as the infection was dubbed, hit different age-groups, displaying a so-called “W-trend”, typically with two spikes in children and the elderly. However, healthy young adults were also affected. In order to avoid alarming the public, several local health authorities refused to reveal the numbers of people affected and deaths. Consequently, it was very difficult to assess the impact of the disease at the time. Although official communications issued by health authorities worldwide expressed certainty about the etiology of the infection, in laboratories it was not always possible to isolate the famous Pfeiffer’s bacillus, which was, at that time, deemed to be the cause of influenza. The first official preventive actions were implemented in August 1918; these included the obligatory notification of suspected cases and the surveillance of communities such as day-schools, boarding schools and barracks. Identifying suspected cases through surveillance, and voluntary and/or mandatory quarantine or isolation, enabled the spread of Spanish flu to be curbed. At that time, these public health measures were the only effective weapons against the disease, as no vaccines or antivirals were available. Virological and bacteriological analysis of preserved samples from infected soldiers and other young people who died during the pandemic period is a major step toward a better understanding of this pandemic and of how to prepare for future pandemics.

Abstract

Highly pathogenic avian influenza (HPAI) H5 clade 2.3.4.4 viruses were first introduced into Europe in late 2014 and re-introduced in late 2016, following detections in Asia and Russia. In contrast to the 2014-15 H5N8 wave, there was substantial local virus amplification in wild birds in Europe in 2016-17 and associated wild bird mortality, with evidence for occasional gene exchange with low pathogenic avian influenza (LPAI) viruses. Since December 2017, several European countries have again reported events or outbreaks with HPAI H5N6 reassortant viruses in both wild birds and poultry, respectively. Previous phylogenetic studies have shown that the two earliest incursions of HPAI H5N8 viruses originated in Southeast Asia and subsequently spread to Europe. In contrast, this study indicates that recent HPAI H5N6 viruses evolved from the H5N8 2016-17 viruses during 2017 by reassortment of a European HPAI H5N8 virus and wild host reservoir LPAI viruses. The genetic and phenotypic differences between these outbreaks and the continuing detections of HPAI viruses in Europe are a cause of concern for both animal and human health. The current co-circulation of potentially zoonotic HPAI and LPAI virus strains in Asia warrants the determination of drivers responsible for the global spread of Asian lineage viruses and the potential threat they pose to public health.

ABSTRACT

Enmetazobactam, formerly AAI101, is a novel penicillanic acid sulfone extended-spectrum β-lactamase inhibitor. The combination of enmetazobactam with cefepime has entered clinical trials to assess safety and efficacy in patients with complicated urinary tract infections. Here, the in vitro activity of cefepime-enmetazobactam was determined for 1,993 clinical isolates of Enterobacteriaceae and Pseudomonas aeruginosa collected in the US and Europe during 2014 and 2015. Enmetazobactam at a fixed concentration of 8 μg/ml lowered the cefepime MIC90from 16 to 0.12 μg/ml for Escherichia coli, >64 to 0.5 μg/ml for Klebsiella pneumoniae, 16 to 1 μg/ml for Enterobacter cloacae, and 0.5 to 0.25 μg/ml for Enterobacter aerogenes. Enmetazobactam did not enhance the potency of cefepime against P. aeruginosa. Applying the CLSI ‘susceptible-dose dependent’ (SDD) breakpoint of 8 μg/ml to cefepime-enmetazobactam for comparative purposes resulted in cumulative inhibitions of 99.9% for E. coli, 96.4% for K. pneumoniae, 97.0% for E. cloacae, 100% for E. aerogenes, 98.1% for all Enterobacteriaceae surveilled, and 82.8% for P. aeruginosa. Comparator susceptibilities for all Enterobacteriaceae were 99.7% for ceftazidime-avibactam, 96.2% for meropenem, 90.7% for ceftolozane-tazobactam, 87% for cefepime (SDD breakpoint), 85.7% for piperacillin-tazobactam, and 81.2% for ceftazidime. For the subset of ESBL-producing K. pneumoniae isolates, addition of 8 μg/ml enmetazobactam to cefepime lowered the MIC90 from >64 to 1 μg/ml, whereas the shift for 8 μg/ml tazobactam was from >64 to 8 μg/ml. Cefepime-enmetazobactam may represent a novel carbapenem-sparing option for empiric treatment of serious Gram-negative infections in settings where ESBL-producing Enterobacteriaceae are expected.

Abstract

Introduction:

Isoniazid (INH) is an essential drug for tuberculosis (TB) treatment. Resistance to INH may increase the likelihood of negative treatment outcome.

Aim:

We aimed to determine the impact of INH mono-resistance on TB treatment outcome in the European Union/European Economic Area and to identify risk factors for unsuccessful outcome in cases with INH mono-resistant TB.

Methods:

In this observational study, we retrospectively analysed TB cases that were diagnosed in 2002–14 and included in the European Surveillance System (TESSy). Multilevel logistic regression models were applied to identify risk factors and correct for clustering of cases within countries.

Results:

A total of 187,370 susceptible and 7,578 INH mono-resistant TB cases from 24 countries were included in the outcome analysis. Treatment was successful in 74.0% of INH mono-resistant and 77.4% of susceptible TB cases. In the final model, treatment success was lower among INH mono-resistant cases (Odds ratio (OR): 0.7; 95% confidence interval (CI): 0.6–0.9; adjusted absolute difference in treatment success: 5.3%). Among INH mono-resistant TB cases, unsuccessful treatment outcome was associated with age above median (OR: 1.3; 95% CI: 1.2–1.5), male sex (OR: 1.3; 95% CI: 1.1–1.4), positive smear microscopy (OR: 1.3; 95% CI: 1.1–1.4), positive HIV status (OR: 3.3; 95% CI: 1.6–6.5) and a prior TB history (OR: 1.8; 95% CI: 1.5–2.2).

Conclusions:

This study provides evidence for an association between INH mono-resistance and a lower likelihood of TB treatment success. Increased attention should be paid to timely detection and management of INH mono-resistant TB.

Challenges and opportunities for the management of infectious diseases in Europes’ prisons: evidence-based guidance

Summary

People in prison have multiple complex health and social care needs. These are likely to be the result of a combination of overlapping, and sometimes interlinked, risk factors for infection, ill-health, and incarceration, such as problem drug use. Incarceration can represent a unique opportunity to make high-quality health care available to people in prison and to target socially deprived groups who are often medically underserved when living in the community they originate from. In recent years, international and European institutions have increasingly acknowledged the importance of treating prison health as an inseparable component of public health. However, numerous challenges hamper the successful implementation of such a concept, including the need for evidence-based decision making, intersectoral partnerships, and better monitoring systems. New initiatives are ongoing in the EU that might contribute to bring about positive changes, such as the publication of the first evidence-based public health guidance on prevention and control of communicable diseases in prison settings.

Highlights

  • The epidemiology of arboviral infection in the Mediterranean region is changing.
  • 2018 was a record year for West Nile virus infections.
  • Crimean-Congo hemorrhagic fever emerged in the Western Europe.
  • Autochthonous chikungunya and dengue cases occurred in the Mediterranean countries.
  • The “One Health” initiative is required for tackling the emerging diseases.

 

Abstract

The epidemiology of viral infections transmitted by arthropods is changing due to a variety of parameters related to the virus, the host and the environment. The Mediterranean region is highly affected by changes in the intensity and extension of global-scale climate patterns, and, due to its location, provides a vulnerable environment for emergence of arboviral diseases. The main arboviruses that pose currently a public health threat in the Mediterranean region are West Nile virus and Crimean-Congo hemorrhagic fever virus and, in less extend, tick-borne encephalitis virus. Usutu virus that affects mainly birds can infect also humans, while Dengue and Chikungunya viruses showed that they are capable to cause sporadic autochthonous cases, and even outbreaks in the Mediterranean region. Sandly-transmitted viruses continue to have a public health impact, and novel ones have been identified. The presence of competent vectors (mainly mosquitoes), combined by arbovirus introduction through viremic travelers returning from endemic regions, prompt for increased surveillance to mitigate the risk for local transmission. In order to tackle efficiently and effectively the emerging arboviral diseases, an integrated “One Health initiative” is required to be maintained, involving public health, animal health and environmental authorities. Awareness of medical and veterinary staff and laboratory capacity are crucial for the early detection of pathogens, while reporting the unusual and enhance surveillance are important.
