Efficacy and safety of cefditoren pivoxil for exacerbations of chronic obstructive pulmonary disease: A prospective multicenter interventional study.

J Infect Chemother 2019 Apr 11. Epub 2019 Apr 11.

Department of Respiratory Medicine, Nagasaki University Hospital, Nagasaki, Japan.

Oral antibiotic therapy for patients with acute exacerbations of chronic obstructive pulmonary disease (COPD) usually involves an aminopenicillin with clavulanic acid, a macrolide, or a quinolone. To date, however, the clinical efficacy and safety of the oral cephalosporin cefditoren pivoxil has not been evaluated in Japanese patients with acute exacerbations of COPD. We conducted a prospective, multicenter, single arm, interventional study from January 2013 to March 2017 to determine the efficacy and safety of oral administration of 200 mg cefditoren pivoxil three times daily for 7 days in a cohort of 29 eligible patients from 15 hospitals.

Electronic address:

Currently, combinations of typical types of antiretroviral agents have been adopted as chemotherapy for human immunodeficiency virus (HIV) infection, comprising two nucleoside analogue reverse transcriptase inhibitors plus one of a non-nucleoside reverse transcriptase inhibitor, an integrase strand-transfer inhibitor, and a protease inhibitor. Although several meta-analyses have been conducted to determine first-line combination antiretroviral therapy, this has yet to be confirmed due to the technical limitation associated. In the present study, we applied a model-based meta-analysis (MBMA) approach, because it allows integration of information from clinical trials with varying dosing, duration, and sampling time points, resulting in enlargement of available data sources.

Investigation of the susceptibility trends in Japan to fluoroquinolones and other antimicrobial agents in a nationwide collection of clinical isolates: A longitudinal analysis from 1994 to 2016.

J Infect Chemother 2019 Apr 3. Epub 2019 Apr 3.

Department of Microbiology and Infectious Diseases, Toho University School of Medicine, Japan.

The susceptibilities of clinical isolates to fluoroquinolones and other antimicrobial agents were surveyed to obtain an accurate understanding of trends in incidence and antimicrobial resistance. The samples were collected from across Japan, biennially or triennially, between 1994 and 2016 and a defined level of resistance to fluoroquinolone was determined. Streptococcus pneumoniae, Streptococcus pyogenes and Haemophilus influenzae exhibited stable and high rates of susceptibility to fluoroquinolones over the period examined. Read More

Fungemia due to Fusarium solani under low-dose liposomal amphotericin B in a patient after cord blood transplantation.

J Infect Chemother 2019 Mar 23. Epub 2019 Mar 23.

Department of Hematology/Oncology, The Institute of Medical Science, The University of Tokyo, Tokyo, Japan.

The introduction of the prophylactic use of antifungal drugs caused the increased occurrence of invasive fungal infections due to previously rare molds, such as fusariosis, after allogeneic hematopoietic stem cell transplantation. We herein report the case of a patient with diffuse large B-cell lymphoma who developed fungemia due to Fusarium solani during liposormal amphotericin B on day 25 after cord blood transplantation (CBT). Because Fusarium species might differ in virulence and drug susceptibility, the sequencing of the internal transcribed spacer region of the ribosomal RNA gene accurately identified Fusarium solani to be the cause of fungemia at the species level.

Pre-transfusion testing for Ebola virus disease patients in serious communicable infectious diseases hospitals in Tokyo: A cross-sectional study.

J Infect Chemother 2019 Feb 28. Epub 2019 Feb 28.

Department of Transfusion Medicine, Tokyo Metropolitan Bokutoh General Hospital, Tokyo, Japan.

Background: Ebola virus disease (EVD) was endemic to Africa in 2014-2016. Supportive therapies have been shown to improve the outcome of EVD, and additional supportive therapy including blood transfusion therapy and external circulation could be needed in the event of a future global outbreak. However, pre-transfusion testing policies and guidelines have not yet been established in Japan. Read More

Diversity of carbapenemases in clinical isolates: The emergence of bla in Bangladesh.

J Infect Chemother 2019 Feb 26. Epub 2019 Feb 26.

Department of Microbiology, University of Dhaka, Dhaka, 1000, Bangladesh. Electronic address:

Global emergence and dissemination of carbapenemases are clinically threatening, notably in countries with endemic bla. To analyze the extent of carbapenemases in Bangladesh, 71 isolates were collected from 7 different clinical sources: wound swab (n = 38), pus (n = 13), urine (n = 9), blood (n = 4), tracheal aspirate (n = 3), pleural fluid (n = 1) and vaginal swab (n = 3) from Dhaka Medical College Hospital, Bangladesh. Among the isolates, 25 were resistant to at least one of the three carbapenems (imipenem, meropenem and doripenem), including 15 being resistant to all. Read More

Viral load and inflammatory cytokine dynamics associated with the prognosis of severe fever with thrombocytopenia syndrome virus infection: An autopsy case.

J Infect Chemother 2019 Feb 26. Epub 2019 Feb 26.

Department of Respiratory Diseases National Institute of Infectious Diseases, Tokyo, Japan.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging tick-borne disease caused by a novel bunyavirus. The mechanism underlying disease progression remains unknown, and effective treatment strategy for SFTS is yet to be completely established, making its increasing incidence and subsequent mortality a great concern. Here, we present the autopsy case of a patient with rapidly progressed, fatal SFTS infection. Read More

Electronic address:

Patients with invasive fungal diseases (IFDs) generally have a high mortality rate, and resistance to antifungal drugs and the high costs associated with it have led to recent problems, necessitating the appropriate use of antifungals. To this end, we launched Antifungal Stewardship Programs (AFSPs) in our hospital. Patients who were systemically administered antifungals from January 2011 to December 2016 were enrolled this study and divided into pre-intervention and intervention groups. Read More

A novel disk-based detection method with superior sensitivity for β-lactamase production in third-generation cephalosporin-resistant Enterobacteriaceae.

J Infect Chemother 2019 May 21;25(5):330-336. Epub 2019 Feb 21.

Department of Infection Control and Prevention, Aichi Medical University Hospital, Aichi, Japan; Department of Clinical Infectious Diseases, Aichi Medical University Hospital, Japan. Electronic address:

Objective: Current phenotypic methods for extended-spectrum β-lactamase (ESBL), AmpC β-lactamase (AmpC), and carbapenemases fail to detect isolates that co-produce other classes of β-lactamases. In this study, we have developed a novel assay (Applied Multiplex Disk Method: AMU-DM) for the phenotypic detection and identification of β-lactamases produced by Enterobacteriaceae.

Methods: We evaluated the performance of the method by comparison with PCR results for 78 Enterobacteriaceae clinical isolates that were positive by the ESBL screening test and negative by the ESBL confirmation test. Read More

Clinical differentiation of infectious mononucleosis that is caused by Epstein-Barr virus or cytomegalovirus: A single-center case-control study in Japan.

J Infect Chemother 2019 Feb 15. Epub 2019 Feb 15.

Department of General Medicine and Emergency Care, Toho University School of Medicine, Japan.

Introduction: Infectious mononucleosis (IM) is a common viral infection that typically causes fever, pharyngitis, and lymphadenopathy in young patients. The Epstein-Barr virus (EBV) is the most common cause of IM, followed by cytomegalovirus (CMV). Given that serological testing is associated with limitations regarding its accuracy, availability, and time to receive results, clinical differentiation based on symptoms, signs, and basic tests would be useful.

J Infect Chemother 2019 Feb 6. Epub 2019 Feb 6.

Department of Infectious Diseases, The University of Tokyo Hospital, Tokyo, Japan.

Bacterial peritonitis, an infection of the ascitic fluid, can be classified etiologically as spontaneous or secondary bacterial peritonitis. The former is mainly caused by portal hypertension and its subsequent effects, whereas the latter is caused by the direct dissemination of bacteria into the peritoneal cavity. Previous reports have described some distinguishing features of these two entities. Read More
