Anti-SARS-CoV-2 nucleocapsid antibody positivity 3 years after COVID-19
This study aimed to comprehensively assess anti-nucleocapsid antibody positivity using diverse commercial and in-house immunoassays among individuals who contracted COVID-19 more than 3 years ago. We enrolled 44 participants with laboratory-confirmed COVID-19 between January and May 2020 from Seoul National University Hospital and its community treatment centers. The results showed anti-nucleocapsid antibody positivities ranged from 45.5% to 87.9% depending upon the immunoassay used. The study highlights the importance of considering the limited anti-nucleocapsid antibody positivity in participants with a distant COVID-19 ...

Helicobacter cholecystus bacteremia in an adult with acute cholecystitis
We report the isolation of Helicobacter cholecystus from a positive blood culture from a 58-year-old man in China who had bacteremia and acute cholecystitis. The patient's condition improved after symptomatic support treatment and subtotal cholecystectomy. This finding suggests that H. cholecystus should be considered as potential human pathogens.PMID:38684428 | DOI:10.7883/yoken.JJID.2023.468 (Source: Japanese Journal of Infectious Diseases)

Clinical Efficacy of Therapeutic Agents for Clostridioides difficile Infection Based on Four Severity Classifications
Jpn J Infect Dis. 2024 Mar 29. doi: 10.7883/yoken.JJID.2023.483. Online ahead of print.ABSTRACTThe Japanese guidelines for the management of Clostridioides difficile infection (CDI) recommend metronidazole (MNZ) for non-severe cases and vancomycin (VCM) for severe cases. Here, we investigated the use of CDI antimicrobials and evaluated their clinical efficacy in four severity classifications and the validity of these classifications. A retrospective chart review was conducted on 137 inpatients with an initial positive C. difficile toxin test and initiation of CDI antimicrobials between April 2015 and March 2019. For the cl...

Association of CovRS two-component regulatory system with NADase induction by Clindamycin treatment in Streptococcus pyogenes
Jpn J Infect Dis. 2024 Mar 29. doi: 10.7883/yoken.JJID.2023.451. Online ahead of print.ABSTRACTThe administration of high-dose clindamycin (CLI) along with penicillin is recommended for the treatment of streptococcal toxic shock syndrome (STSS). However, CLI-resistant strains have been identified worldwide. Firstly, in this study, some CLI-resistant strains showed increased extracellular activities of the NAD- glycohydrolase (NADase) exotoxin after CLI treatment. This result supported our previous conclusion that not only CLI-susceptible but also CLI-resistant S. pyogenes strains show the CLI-dependent NADase induction. Se...

Usefulness of a pluralistic approach in sentinel surveillance: seasonal influenza activity based on case counts per sentinel site in the National Epidemiological Surveillance of Infectious Diseases Program and test counts, case counts, and test positivity from the National Hospital Organization
Jpn J Infect Dis. 2024 Mar 29. doi: 10.7883/yoken.JJID.2023.368. Online ahead of print.ABSTRACTIn Japan, based on the National Epidemiological Surveillance of Infectious Diseases (NESID) Program, influenza cases from ~5,000 sentinel sites are monitored weekly as part of influenza surveillance (as number of influenza cases/sentinel site). One limitation is that the number of influenza tests conducted is not reported. Separately, the National Hospital Organization (NHO), with ~140 hospitals, routinely publishes three indicators: number of influenza tests, influenza-positive case counts, and test positivity. We used NESID and...
