T Tängdén, C G Giske
The prevalence of carbapenem-resistant Gram-negative bacilli is on the rise worldwide, posing a major public health threat. Previously, this was mostly a problem in Pseudomonas and Acinetobacter, but during the last decade, carbapenem resistance has escalated in medically important species such as Klebsiella pneumoniae and Escherichia coli. In particular, the rising trend in E. coli is of concern, as this may lead to almost untreatable community-acquired infections. Resistance is conferred by carbapenemases, which are beta-lactamases that can breakdown essentially all beta-lactams...

The dramatic increase in the prevalence and clinical impact of infections caused by bacteria producing carbapenemases is a global health concern. Carbapenemase production is especially problematic when encountered in members of the family Enterobacteriaceae. Due to their ability to readily spread and colonize patients in health care environments, preventing the transmission of these organisms is a major public health initiative and coordinated international effort is needed to contain the risk of infection...

Co-infection frequency and impact among influenza-associated acute respiratory distress syndrome (ARDS) patients requiring extracorporeal membrane oxygenation (ECMO) are not known. This retrospective, observational analysis concerned data prospectively collected from patients admitted to our medical intensive care unit (ICU) who received ECMO support for influenza-associated ARDS between 2009 and 2016. Co-infection was defined as occurring within 48 hours following ICU admission. Among the 77 ARDS patients requiring ECMO support, 39 (51%) developed co-infections, with Staphylococcus aureus (18 (46%) of the co-infected) being the most prevalent pathogen...

Methicillin-resistant strains of Staphylococcus aureus (MRSA) are of particular significance for the management of patients with airway infections, since the disease course is often complicated and treatment rendered difficult by multiple resistance. Their prevalence is now slowly declining, but still alarmingly high. Hospital-acquired infections are predominant, but hospital-associated and community-acquired infections do occur, as do rare infections with livestock-acquired strains. Non-nosocomial strains are characterized by different pathogenic factors and a different spectrum of antibacterial resistance; they often have a threatening disease course...

INTRODUCTION: Enterococci are recognized as opportunistic pathogens, as well as commensals in both humans and animals. They are an important cause of nosocomial infections, difficult to treat, as the organism have intrinsic and acquired resistance to many antibiotics. AIM: To isolate and identify clinically relevant Enterococcus up to species level from all the clinical samples processed in the microbiology laboratory and also to study their resistance pattern. MATERIALS AND METHODS: A prospective study was carried out for a period of one year from May 2014 to April 2015 at the Department of Microbiology, Subharti Medical College, Meerut, Uttar Pradesh, India...

REVIEW
Benoit Pilmis, Vincent Jullien, Alexis Tabah, Jean-Ralph Zahar, Christian Brun-Buisson
Several studies suggest that alternatives to carbapenems, and particulary beta-lactam/beta-lactamase inhibitor combinations, can be used for therapy of extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE)-related infections in non-ICU patients. Little is known concerning ICU patients in whom achieving the desired plasmatic pharmacokinetic/pharmacodynamic (PK/PD) target may be difficult. Also, in vitro susceptibility to beta-lactamase inhibitors might not translate into clinical efficacy. We reviewed the recent clinical studies examining the use of BL/BLI as alternatives to carbapenems for therapy of bloodstream infection, PK/PD data and discuss potential ecological benefit from avoiding the use of carbapenems...

Sepsis and septic shock remain serious infections with reported mortality rates in excess of forty percent. Timely antibiotic therapy in sepsis and septic shock is recognized as an important determinant of outcome. However, the administration of ineffective empiric treatment (IET) (an initial antibiotic regimen that is not active against the identified pathogen(s) based on in vitro susceptibility testing) is associated with excess mortality compared to effective empiric treatment (EET). We examined all hospitalized patients between January 2010 and October 2015 at Barnes-Jewish Hospital with the presence of a sterile site (blood, or pleural, abdominal, cerebrospinal, synovial, and pericardial fluid) culture positive for Gram-negative (GN) bacteria combined with primary or secondary ICD-9-CM codes for severe sepsis (995...

REVIEW

Iron is an essential trace metal for nearly all infectious microorganisms, and host defense mechanisms target this dependence to deprive microbes of iron. This review highlights mechanisms that are activated during infections to restrict iron on mucosal surfaces, in plasma and extracellular fluid, and within macrophages. Iron overload disorders, such as hereditary hemochromatosis or β-thalassemia, interfere with iron-restrictive host responses, and thereby cause increased susceptibility to infections with microbes that can exploit this vulnerability...

Severe malaria is common in tropical countries in Africa, Asia, Oceania and South and Central America. It may also occur in travelers returning from endemic areas. Plasmodium falciparum accounts for most cases, although P vivax is increasingly found to cause severe malaria in Asia. Cerebral malaria is common in children in Africa, manifests as coma and seizures, and has a high morbidity and mortality. In other regions, adults may also develop cerebral malaria but neurological sequelae in survivors are rare...

BACKGROUND AND OBJECTIVE: Urinary tract infection (UTI) is a frequent disorder of childhood, yet the proper approach for a child with UTI is still a matter of controversy. The objective of this study was to critically compare current guidelines for the diagnosis and management of UTI in children, in light of new scientific data. METHODS: An analysis was performed of the guidelines from: American Academy of Pediatrics (AAP), National Institute for Health and Care Excellence (NICE), Italian Society of Pediatric Nephrology, Canadian Paediatric Society (CPS), Polish Society of Pediatric Nephrology, and European Association of Urology (EAU)/European Society for Pediatric Urology (ESPU)...

Central venous catheters (CVC), used for the management of children with hemato-oncological disorders, are burdened by a significant incidence of mechanical, infective, or thrombotic complications. These complications favor an increasing risk in prolongation of hospitalization, extra costs of care, and sometimes severe life-threatening events. No guidelines for the management of CVC-related occlusion and CVC-related thrombosis are available for children. To this aim, members of the coagulation defects working group and the supportive therapy working group of the Italian Association of Pediatric Hematology and Oncology (AIEOP) reviewed the pediatric and adult literature to propose the first recommendations for the management of CVC-related occlusion and CVC-related thrombosis in children with hemato-oncological disorders...

Introduction of 13-valent pneumococcal conjugate vaccine in the United States was not associated with a significant change in prevalence of penicillin resistance in nonvaccine type serotypes because of the variable success of highly resistant serotypes. Differences in regional serotype distribution and serotype-specific resistance contributed to geographic heterogeneity of penicillin resistance.

PURPOSE OF REVIEW: Pneumococcal infections are a major cause of morbidity and mortality worldwide. In recent years, Streptococcus pneumoniae has shown increasing resistance to a several antibiotics, becoming a worldwide problem. The impact of antibiotic resistance of S. pneumoniae on clinical outcomes is still controversial. The principal reason for this controversy is the existence of several factors related to the patients and to the pathogen that may influence how antibiotic resistance patterns affect clinical outcomes...

Infections with Corynebacterium striatum have been described in the literature over the last 2 decades, with the majority being bacteremia, central line infections, and occasionally, endocarditis. In recent years, the frequency of C. striatum infections appears to be increasing; a factor likely contributing to this is the increased ease and accuracy of the identification of Corynebacterium spp., including C. striatum, from clinical cultures. The objective of this study was to retrospectively characterize C...

REVIEW
Alina Iovleva, Yohei Doi
Carbapenem-resistant Enterobacteriaceae (CRE) have emerged as a major threat. Commonly used antibiotics are generally inactive against CRE. Therefore, timely detection of CRE is of paramount importance. Among CRE, those producing carbapenem-hydrolyzing β-lactamase enzymes (carbapenemase-producing Enterobacteriaceae) are particularly of concern because they tend to spread, and treatment is difficult. The carbapenemase groups most commonly encountered include KPC, NDM, and OXA-48. Treatment options are limited and include combinations of polymyxins, tigecycline, aminoglycosides, or carbapenems; newer agents with activity against CRE and better safety profiles are becoming available and will likely emerge as the preferred therapy...
