Fecal microbiota transplant (FMT) has emerged as a highly efficacious treatment for difficult cases of refractory and/or recurrent Clostridium difficile infection (CDI). There have been many well-conducted randomized controlled trials and thousands of patients reported in case series that describe success rates of approximately 90% following one or more FMT. Although the exact mechanisms of FMT have yet to be fully elucidated, replacement or restoration of a 'normal' microbiota (or at least a microbiota resembling those who have never had CDI) appears to have a positive effect on the gut dysbiosis that is thought to exist in these patients...

REVIEW
Thomas V Riley, Tomomi Kimura
To increase understanding of the epidemiology, risks, consequences and resource utilization of Clostridium difficile infection (CDI) in Japan, a systematic literature review was undertaken of relevant publications from January 2006 to November 2017. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and methods, 55 articles met the criteria for full review. The majority (58%) of studies were from a single site, with the most recent data from 2015. The incidence, reported prevalence and recurrence rate of CDI in Japan were 0...

REVIEW
Kenneth V I Rolston, Lior Nesher
Published literature on post-obstructive pneumonia is difficult to find and consists mainly of case reports or small case series. This entity is encountered most often in patients with advanced lung malignancy but is also occasionally seen in patients with community-acquired pneumonia (CAP). There are substantial differences in the manifestations, treatment, and outcomes of post-obstructive pneumonia in these two settings. When obstruction is present in patients with CAP, it is almost always secondary to an underlying pulmonary malignancy...

INTRODUCTION: Physiologic changes during pregnancy may impact the pharmacokinetics of drugs. In addition, efficacy and safety/tolerability concerns have been identified for some antiretroviral agents. METHODS: Human immunodeficiency virus (HIV)-1-infected pregnant women (18-26 weeks gestation) receiving the non-nucleoside reverse transcriptase inhibitor rilpivirine 25 mg once daily were enrolled in this phase 3b, open-label study examining the impact of pregnancy on the pharmacokinetics of rilpivirine when it is given in combination with other antiretroviral agents...

REVIEW

Invasive aspergillosis (IA) is a serious opportunistic infection, which has increasingly been recognized as an emerging disease of non-neutropenic patients. In this group of patients, the diagnosis of IA can be challenging owing to the lack of specificity of symptoms, the difficulty in discriminating colonization from infection, and the lower sensitivity of microbiological and radiological tests compared with immunocompromised patients. The aim of this article is to present to clinicians a critical review on the management of IA in non-neutropenic patients...

INTRODUCTION: Varicella zoster virus (VZV) causes chicken pox and herpes zoster and is a self-limiting disease in healthy children. Vaccination is recommended for children, adolescents, and adults. This study discusses a healthy pediatric patient with negative immunoglobulin (Ig) G VZV antibody (Ab) status after two doses of varicella vaccine and then subsequently re-immunized. Since measurement of serum IgG titers alone may not reflect vaccine protection, we further evaluated cell-mediated and humoral immune responses before and after re-immunization...

INTRODUCTION: Antibiotic prescribing rates vary substantially across regions in the USA. Whether these differences are driven primarily by a greater tendency to treat certain infections (i.e., overtreatment) in certain regions or differences in the tendency to diagnose certain infections (i.e., overdiagnosis) is poorly understood. METHODS: We examined data from 2012 to 2013 using the National Ambulatory Medical Care Survey, which is a nationally representative sample of visits to office-based physicians...

Cytomegalovirus (CMV) is an agent of global infection, and its acquisition in a population is characterized by an age-dependent rise in seropositivity. After primary infection, CMV remains in the host cells in latent form, and it can reactivate in the case of immune suppression. The risk of CMV recurrence is dependent on the level of incompetency of the immune system, manifested as an impairment of T-cell immunity, including the presence and function of CMV-specific cytotoxic T lymphocytes. This article presents data on the incidence of CMV recurrence in groups of immunocompromised patients, including allogeneic hematopoietic stem cell transplantation (HSCT) patients and other groups of patients, based on a summary of reported data...

Although current therapies can be successful at suppressing hepatitis B viral load, long-term viral cure is not within reach. Subsequent strategies combining pegylated interferon alfa with nucleoside/nucleotide analogues have not resulted in any major paradigm shift. An improved understanding of the hepatitis B virus (HBV) lifec ycle and virus-induced immune dysregulation has, however, revealed many potential therapeutic targets, and there are hopes that treatment of hepatitis B could soon be revolutionized...

INTRODUCTION: Approximately 30% of all outpatient antimicrobials are inappropriately prescribed. Currently, antimicrobial prescribing patterns in emergency departments (ED) are not well described. Determining inappropriate antimicrobial prescribing patterns and opportunities for interventions by antimicrobial stewardship programs (ASP) are needed. METHODS: A retrospective chart review was performed among a random sample of non-admitted, adult patients who received an antimicrobial prescription in the ED from January 1 to December 31, 2015...

INTRODUCTION: Respiratory syncytial virus (RSV) is the leading cause of hospitalization among infants in the United States, and the risk for RSV hospitalizations is greater for infants born preterm. Recent studies in preterm and term infants have shown that RSV hospitalization rates vary considerably depending on infant chronologic age. This study sought to aggregate the data available from published literature and from nationally representative databases of US infant hospitalizations to generate a composite description of the effect of young chronologic age on RSV hospitalizations among US preterm and term infants by individual month of age...

INTRODUCTION: Lower respiratory tract infections (LRTIs) are a major cause of morbidity and death. Because of changes in how LRTIs are defined coupled with the increasing prevalence of drug resistance, there is a gap in knowledge regarding the current burden of antimicrobial use for Centers for Disease Control and Prevention (CDC)-defined LRTIs. We describe the infection characteristics, antibiotic consumption, and clinical and economic outcomes of patients with Gram-negative (GN) LRTIs treated in intensive care units (ICUs)...

INTRODUCTION: Palivizumab is indicated for the prevention of respiratory syncytial virus (RSV) infection in high-risk children. Previous palivizumab utilization studies examined prior authorization claims but did not examine utilization within insured populations as a whole. This study describes outpatient palivizumab utilization trends and characterizes high-risk infants receiving palivizumab within Medicaid- and commercially insured populations. METHODS: Infants born July 1, 2003 through June 30, 2013 were identified in the MarketScan(®) Multistate Medicaid and Commercial claims databases...

INTRODUCTION: Vancomycin remains one of our essential antibiotics after fifty years of treating serious infections such as methicillin-resistant Staphylococcus aureus. Vancomycin, unlike many other antibiotic agents, requires individualized dosing and monitoring of serum drug levels to ensure it is efficacious, to minimize toxicity, and to limit the development of antibiotic resistance. These issues have led to numerous vancomycin clinical practice guidelines being published in recent years including several key national guidelines...

INTRODUCTION: Mucoid Pseudomonas aeruginosa (MP) strains in cystic fibrosis (CF) patients are thought to initiate the chronic infection stage of CF and are associated with pulmonary function decline. OBJECTIVES: The purpose of this study was to assess the susceptibility of MP strains to ceftolozane/tazobactam and the efficacy of ceftolozane/tazobactam against MP strains compared with those for standard-of-care antipseudomonal antibiotics. METHODS: Ten clinical isolates of MP from CF patients were tested for susceptibility with Etest and time-kill analysis with ceftolozane/tazobactam compared with ceftazidime, cefepime, ciprofloxacin, meropenem, tobramycin, and polymyxin B...

INTRODUCTION: Infection is a major threat to wound healing and a leading cause of graft loss in patients undergoing meshed skin grafts (MSGs). Therefore, topical antisepsis is important in the overall treatment scheme. METHODS: An exploratory satellite group of 14 patients with infected MSGs were enrolled as part of a prospective, randomized, controlled, parallel-group, open-label, pilot Phase II study that investigated the efficacy and tolerability of 3% liposomal povidone-iodine hydrogel (PVP-ILH, Repithel(®); RepiGel(®)) versus chlorhexidine gauze in non-infected MSGs...

INTRODUCTION: The current extent of migration to the European continent is associated with exceptional humanitarian challenges. In 2015, Western Europe faced an enormous immigration of refugees with largely unknown protection status against communicable diseases. To adapt vaccination strategies, we aimed at assessing seroprevalences against three of the most relevant vaccine preventable diseases (VPD) in a large representative cohort. METHODS: IgG seroprevalences for rubella, varicella (n = 554) and measles (n = 552) were analyzed in inhabitants of a Northern German refugee camp in the summer of 2015...
