#1
Matteo Bassetti, Alessia Carnelutti, Elda Righi
PURPOSE OF REVIEW: Methicillin-resistant Staphylococcus aureus (MRSA) has become a major public health issue worldwide over the last years. MRSA is frequently implicated in the development of skin and soft tissue infections, leading to significant increases in morbidity, mortality and overall healthcare costs. RECENT FINDINGS: In order to face the threat of MRSA, major changes in clinical management of skin and soft tissue infections are required. The identification of populations at risk for the acquisition of infections due to MRSA, together with the improvement of the diagnostic techniques, is paramount...

PURPOSE OF REVIEW: 18F-Fluorodeoxyglucose positron emission tomography/computed tomography is a well-established technique for diagnosis and management of a number of neoplastic conditions. However, in recent years the body of literature regarding its potential role in infectious diseases has progressively increased, with promising results. RECENT FINDINGS: So far 18F-fluorodeoxyglucose positron emission tomography/computed tomography has a well-established role and is recommended by guidelines only in a few settings, such as prosthetic valve endocarditis, vascular device infections, and chronic osteomyelitis...

Katerina Kaziani, Adamantia Sotiriou, George Dimopoulos
PURPOSE OF REVIEW: Increasing antimicrobial resistance is a worldwide phenomenon that is threatening public health. Lower respiratory infections are one of the leading causes of morbidity that contribute to antibiotic consumption and thus the emergence of multidrug-resistant microbial strains. The goal of shortening antibiotic regimens' duration in common bacterial infections has been prioritized by antimicrobial stewardship programs as an action against this problem. RECENT FINDINGS: Data coming from randomized controlled trials, meta-analyses, and systematic reviews support the shortening of antimicrobial regimens in community-acquired, hospital-acquired, and ventilator-associated pneumonia...

PURPOSE OF REVIEW: Discovery of a normal lung microbiome requires reassessment of our concepts of HAP/VAP pathogenesis and has important implications for clinical diagnosis and management. RECENT FINDINGS: Changes in the microbiome of dental plaque are associated with increased risk of HAP/VAP. A transition to a lung microbiome enriched with gut flora is found in ARDS with an increased inflammatory response in patients with this change in microbial flora. A characteristic microbiome pattern of higher amounts of bacterial DNA, lower community diversity, and greater relative abundance of a single species characterize pneumonia and occasionally identify bacteria not found in culture...

Mohd H Abdul-Aziz, Jeffrey Lipman, Jason A Roberts
PURPOSE OF REVIEW: Nosocomial pneumonia caused by multidrug-resistant pathogens is increasing in the ICU, and these infections are negatively associated with patient outcomes. Optimization of antibiotic dosing has been suggested as a key intervention to improve clinical outcomes in patients with nosocomial pneumonia. This review describes the recent pharmacokinetic/pharmacodynamic data relevant to antibiotic dosing for nosocomial pneumonia caused by multidrug-resistant pathogens. RECENT FINDINGS: Optimal antibiotic treatment is challenging in critically ill patients with nosocomial pneumonia; most dosing guidelines do not consider the altered physiology and illness severity associated with severe lung infections...

PURPOSE OF REVIEW: The pathogenesis and impact of coinfection, in particular bacterial coinfection, in influenza are incompletely understood. This review summarizes results from studies on bacterial coinfection in the recent pandemic influenza outbreak. RECENT FINDINGS: Systemic immune mechanisms play a key role in the development of coinfection based on the complexity of the interaction of the host and the viral and bacterial pathogens. Several studies were performed to determine the point prevalence of bacterial coinfection in influenza...

Zaid H Tafesh, Elizabeth C Verna
PURPOSE OF REVIEW: Nonalcoholic fatty liver disease (NAFLD) is common among patients living with HIV and may lead to liver-related morbidity and mortality. RECENT FINDINGS: The prevalence of NAFLD among patients with HIV is increasingly well described due to new noninvasive techniques to quantify hepatic steatosis and fibrosis. Patients with HIV may be at increased risk of disease progression, though high-quality natural history studies are not available. The high rates of metabolic syndrome, dyslipidemia and insulin resistance may partially account for this excess risk, though the impact of HIV itself, antiretroviral medications and dysregulation of the gut-liver axis likely play important roles...

David B Gootenberg, Jeffrey M Paer, Jesus-Mario Luevano, Douglas S Kwon
PURPOSE OF REVIEW: Despite HIV therapy advances, average life expectancy in HIV-infected individuals on effective treatment is significantly decreased relative to uninfected persons, largely because of increased incidence of inflammation-related diseases, such as cardiovascular disease and renal dysfunction. The enteric microbial community could potentially cause this inflammation, as HIV-driven destruction of gastrointestinal CD4 T cells may disturb the microbiota-mucosal immune system balance, disrupting the stable gut microbiome and leading to further deleterious host outcomes...

Diarmuid Nugent, Richard Gilson
PURPOSE OF REVIEW: Controlling the HIV epidemic remains a major public health challenge, and there is an urgent need for novel prevention strategies. Preexposure prophylaxis (PrEP) refers to the use of antiretrovirals in HIV-negative people at high risk to prevent infection and has the potential to be an important component in the global effort to end the HIV epidemic by 2030. We review the current evidence for the safety and efficacy of PrEP in its different forms and address emergent issues and concerns regarding its implementation...

Joseph Kamtchum-Tatuene, Benjamin L Makepeace, Laura Benjamin, Matthew Baylis, Tom Solomon
PURPOSE OF REVIEW: Wolbachia is a genus of Gram-negative intracellular bacteria that is naturally found in more than half of all arthropod species. These bacteria cannot only reduce the fitness and the reproductive capacities of arthropod vectors, but also increase their resistance to arthropod-borne viruses (arboviruses). This article reviews the evidence supporting a Wolbachia-based strategy for controlling the transmission of dengue and other arboviral infections. RECENT FINDINGS: Studies conducted 1 year after the field release of Wolbachia-infected mosquitoes in Australia have demonstrated the suppression of dengue virus (DENV) replication in and dissemination by mosquitoes...

T Charles Witzel, Alison J Rodger
PURPOSE OF REVIEW: The purpose of this review is to describe the most recent literature on outcomes and issues associated with HIV self-testing (HIVST). RECENT FINDINGS: HIVST is acceptable to a range of populations in a variety of contexts, particularly if users' values and preferences are taken into account in intervention development. Approaches being explored in ongoing and planned studies are the efficacy of HIVST to increase diagnosis of long-standing prevalent infections and to reduce the interval between HIV transmission and diagnosis, particularly in high-incidence groups...

PURPOSE OF REVIEW: Anal cancer is a serious health problem in HIV-positive men who have sex with men, and precursor lesions, anal intraepithelial neoplasia, are well defined. Given the similarities with cervical cancer, screening for and treatment of anal intraepithelial neoplasia might prevent anal cancer. Screening programmes should meet the Wilson and Jungner criteria. We used these criteria to evaluate the current body of evidence supporting a screening programme for anal dysplasia...

PURPOSE OF REVIEW: Bacterial meningitis is a medical emergency and is associated with a high disease burden. We reviewed recent progress in the management of patients with community-acquired bacterial meningitis. RECENT FINDINGS: The worldwide burden of disease of bacterial meningitis remains high, despite the decreasing incidence following introduction of routine vaccination campaigns. Delay in diagnosis and treatment remain major concerns in the management of acute bacterial meningitis...

PURPOSE OF REVIEW: HIV replication and immunodeficiency are important risk factors for chronic kidney disease (CKD). Widespread use of antiretrovirals that may affect kidney function underscores the need for monitoring kidney function, allowing early detection of drug-induced kidney injury and identification of patients who may benefit from antiretroviral therapy switches. RECENT FINDINGS: Several cohorts have reported an increased incidence of CKD with tenofovir [tenofovir disoproxil fumarate (TDF)], atazanavir, and lopinavir, and CKD risk scores have been developed to identify those most at risk of kidney disease progression while receiving these agents...
