Tuberculosis kills more people than any other infectious disease. Three pivotal trials testing 4-month regimens failed to meet non-inferiority margins; however, approximately four-fifths of participants were cured.

Through a pooled analysis of patient-level data with external validation, we identify populations eligible for 4-month treatment, define phenotypes that are hard to treat and evaluate the impact of adherence and dosing strategy on outcomes.

In 3,405 participants included in analyses, baseline smear grade of 3+ relative to <2+, HIV seropositivity and adherence of ≤90% were significant risk factors for unfavorable outcome.

Four-month regimens were non-inferior in participants with minimal disease defined by <2+ sputum smear grade or non-cavitary disease. A hard-to-treat phenotype, defined by high smear grades and cavitation, may require durations >6 months to cure all.

Regimen duration can be selected in order to improve outcomes, providing a stratified medicine approach as an alternative to the ‘one-size-fits-all’ treatment currently used worldwide…

Abstract

We examined the relationship between maternal depressive symptoms in late pregnancy and Epstein-Barr virus reactivation before delivery. In this prospective observational study, prevalence of Epstein-Barr virus reactivation within one week before delivery was compared between 163 pregnant women with depressive symptoms at 33 to 34 weeks of gestation and a computer-generated control group of 163 pregnant healthy women without depressive symptoms. Depressive symptoms at 33 to 34 weeks of gestation were significantly related to the prevalence of Epstein-Barr virus reactivation before delivery after adjustment for potential confounders (adjusted OR = 2.74, 95%CI: 1.23-6.08). Compared to that in the control group, the prevalence of Epstein-Barr virus reactivation was higher in women with depressive symptoms accompanied by higher negative coping (24.2% compared with 7.9%; adjusted OR = 3.67, 95%CI: 1.47-9.16). Maternal depressive symptoms in late pregnancy are associated with Epstein-Barr virus reactivation, and this association could be moderated by maternal coping style.

Attributable deaths and disability-adjusted life-years caused by infections with antibiotic-resistant bacteria in the EU and the European Economic Area in 2015: a population-level modelling analysis

LANCET Infectious Diseases November 5, 2018

Background

Infections due to antibiotic-resistant bacteria are threatening modern health care. However, estimating their incidence, complications, and attributable mortality is challenging. We aimed to estimate the burden of infections caused by antibiotic-resistant bacteria of public health concern in countries of the EU and European Economic Area (EEA) in 2015, measured in number of cases, attributable deaths, and disability-adjusted life-years (DALYs).

Methods

We estimated the incidence of infections with 16 antibiotic resistance–bacterium combinations from European Antimicrobial Resistance Surveillance Network (EARS-Net) 2015 data that was country-corrected for population coverage. We multiplied the number of bloodstream infections (BSIs) by a conversion factor derived from the European Centre for Disease Prevention and Control point prevalence survey of health-care-associated infections in European acute care hospitals in 2011–12 to estimate the number of non-BSIs. We developed disease outcome models for five types of infection on the basis of systematic reviews of the literature.

Findings

From EARS-Net data collected between Jan 1, 2015, and Dec 31, 2015, we estimated 671 689 (95% uncertainty interval [UI] 583 148–763 966) infections with antibiotic-resistant bacteria, of which 63·5% (426 277 of 671 689) were associated with health care. These infections accounted for an estimated 33 110 (28 480–38 430) attributable deaths and 874 541 (768 837–989 068) DALYs. The burden for the EU and EEA was highest in infants (aged <1 year) and people aged 65 years or older, had increased since 2007, and was highest in Italy and Greece.

Interpretation

Our results present the health burden of five types of infection with antibiotic-resistant bacteria expressed, for the first time, in DALYs. The estimated burden of infections with antibiotic-resistant bacteria in the EU and EEA is substantial compared with that of other infectious diseases, and has increased since 2007. Our burden estimates provide useful information for public health decision-makers prioritising interventions for infectious diseases.

IMAGES IN CLINICAL MEDICINE – Spinal Brucellosis

N Engl J of Med October 25, 2018 V.379 P.e28

Christine Cho, M.D., and Michihiko Goto, M.D.

A 62-year-old man presented to the emergency department with a 6-month history of worsening low back pain, fevers, chills, night sweats, and weight loss. He regularly traveled to Mexico and had occasionally consumed unprocessed dairy products. He had no history of tuberculosis infection or known exposure. Laboratory studies revealed a white-cell count of 10,600 per cubic millimeter (reference range, 3700 to 10,500) and an erythrocyte sedimentation rate of 65 mm per hour (reference range, 0 to 15)…..

Should Acute Q-Fever Patients be Screened for Valvulopathy to Prevent Endocarditis?

Clinical Infectious Diseases August 1, 2018 V.67 N.3 P.360-366

Marit M A de Lange; Laura E V Gijsen; Cornelia C H Wielders; Wim van der Hoek; Arko Scheepmaker

We found no difference in occurrence of chronic Q-fever between patients with or without a newly detected valvulopathy at time of acute Q-fever diagnosis. Thus, universal screening is not justified and would lead to unnecessary and undesirable long-term antibiotic use.

Gepotidacin for the Treatment of Uncomplicated Urogenital Gonorrhea: A Phase 2, Randomized, Dose-Ranging, Single-Oral Dose Evaluation

Clinical Infectious Diseases August 15, 2018 V.67 N.4 P.505-512

Stephanie N Taylor; David H Morris; Ann K Avery; Kimberly A Workowski; Byron E Batteiger

In this phase 2 study, single oral doses of gepotidacin were ≥95% effective for bacterial eradication in culture-proven uncomplicated urogenital gonorrhea. New antibiotics for drug-resistant Neisseria gonorrhoeae are urgently needed. With additional evaluation, gepotidacin may provide an alternative therapeutic option.

Abstract

Representatives of the Argentine Society of Infectious Diseases (SADI) and the Argentine Society of Intensive Therapy (SATI) worked together on the development of specific recommendations for the diagnosis, treatment and prevention of ventilator-associated pneumonia (VAP). The methodology used was the analysis of the literature published in the last 15 years, complemented with the opinion of experts and local data. This document aims to offer basic tools to optimize diagnosis based on clinical and microbiological criteria, orientation in empirical and targeted antibiotic schemes, news on posology and administration of antibiotics in critical patients and to promote effective measures to reduce the risk of VAP. It also offers a diagnostic and treatment algorithm and considerations on inhaled antibiotics. The joint work of both societies -infectious diseases and intensive care- highlights the concern for the management of VAP and the importance of ensuring improvement in daily practices. This guideline established recommendations to optimize the diagnosis, treatment and prevention of VAP in order to reduce morbidity and mortality, days of hospitalization, costs and resistance to antibiotics due to misuse of antimicrobials.
