Article Synopsis
  • In South Korea, the population at risk for pneumococcal diseases is highly vaccinated, but the distribution of pneumococcal serotypes is changing, complicating vaccine administration.
  • A cohort study analyzed 5,009 patients with community-acquired pneumonia (CAP), revealing serotype 3 as the most prevalent, even among fully vaccinated individuals, with advanced age and other health factors increasing the risk of 30-day mortality.
  • The findings indicate that while vaccination with the 23-valent pneumococcal polysaccharide vaccine (PPSV23) can lower mortality rates, serotypes 3 and 19A remain common causes of pneumococcal infections, challenging the effectiveness of current vaccination strategies.

Article Synopsis
  • - The study investigated invasive pneumococcal disease (IPD) in adults during the late stage of the PCV13 vaccine era, finding a significant prevalence of specific serotypes and high rates of antibiotic resistance.
  • - Among 160 IPD cases analyzed, serotypes related to the pneumococcal vaccines (PCV13 and PPSV23) were identified, with serotype 3 and 19A being the most common, highlighting the ongoing risk to older and chronically ill individuals.
  • - Notably, over 32% of pneumococcal isolates showed non-susceptibility to the antibiotic ceftriaxone, particularly in specific serotypes, indicating a concerning trend in antimicrobial resistance that may impact

Background: Critically ill patients in intensive care units (ICUs) often acquire opportunistic infections or are colonized by vancomycin-resistant enterococci (VRE), which limits therapeutic options and results in high case-fatality rates. In clinical practice, the beneficial effects of universal chlorhexidine gluconate (CHG) bathing on the control of VRE remain unclear. This study aimed to investigate whether 2% CHG daily bathing reduced the acquisition of VRE in the setting of a medical ICU (MICU) with VRE endemicity.

During the 2019 domestic measles outbreak in Korea, measles occurred in healthcare workers with two doses of the measles, mumps and rubella vaccine, and the strict application of the Occupational Safety and Health Act required medical institutions to identify healthcare workers' immunity to measles and vaccinate the susceptible pockets. In response to the frontline medical institutions' request to review the measles recommendations and guidelines, the Korean Society of Infectious Diseases held a roundtable discussion on the causes of measles outbreak, timing of vaccinations, antibody tests, and booster vaccinations for healthcare workers, and financial support from the government and municipality as well as response strategies against the outbreak in healthcare settings. In Korea, the seroprevalence of measles is decreasing in the vaccine-induced immunity group during the maintenance of measles elimination over several years.

Hospital-based surveillance for adverse events was conducted on healthcare workers after they received the first dose of coronavirus disease 2019 (COVID-19) vaccine. Among the two new platform vaccines (messenger RNA- and adenoviral vector-based vaccines), the rates of systemic adverse events were significantly higher among adenovirus-vectored vaccine recipients.

Background: The massive outbreak of the novel coronavirus disease 2019 (COVID-19) in Daegu city and Gyeongsangbuk-do, Republic of Korea (ROK), caused the exponential increase in new cases exceeding 5000 within 6 weeks. Therefore, the community treatment center (CTC) with a digital health care monitoring system based on the smartphone application and personal health record platform (PHR) was implemented. Thus, we report our experience in one of the CTCs to investigate the role of CTC and the feasibility of the digital health care monitoring system in the COVID-19 pandemic.

Purpose: In the recent antiretroviral therapy (ART) era, a large proportion of Korean patients with human immunodeficiency virus (HIV) infection were shown to have low CD4 cell counts at diagnosis and during ART initiation. We investigated the survival trends in patients living with HIV/acquired immunodeficiency syndrome (AIDS) in Korea who started ART in the 2000s, and evaluated the risk factors for mortality to elucidate the association between survival and low CD4 cell counts at ART initiation.

Materials And Methods: Patients with HIV infection who were aged >18 years and had started ART between 2001 and 2015 in the Korean HIV/AIDS cohort study were enrolled.

Background: Echinocandins are recommended for the treatment of invasive candidiasis and candidemia. However, there are few studies comparing anidulafungin and micafungin in terms of efficacy and safety. The objective of this study was to evaluate the clinical efficacy and safety between anidulafungin and micafungin treatment for adult patients with candidemia.

Background: Even though Korea was known to have the highest number of coronavirus disease-2019 (COVID-19) infection in the early phase of the pandemic, Korea was able to successfully flatten the curve in a short period of time without extreme measures. We compared the status of cancer management before and after COVID-19 and analysed how cancer care continuity was maintained in Korea.

Patients And Methods: We investigated the medical records on the number of cancer diagnosis, cancer surgery, radiation therapy and scheduled chemotherapy conducted in Korea University Anam Hospital from January 1 to April 30, 2019 and from the same period in 2020.

To overcome increasing bacterial resistance to conventional antibiotics, many antimicrobial peptides (AMPs) derived from host defense proteins have been developed. However, there are considerable obstacles to their application to systemic infections because of their low bioavailability. In the present study, we developed an AMP derived from Romo1 (AMPR-11) that exhibits a broad spectrum of antimicrobial activity.

Sepsis is one of the significant causes of morbidity and mortality. The burden caused by sepsis has continued to increase in recent years in the Korea, highlighting the urgent need for the implementation of strategies to improve sepsis treatment outcomes. We therefore designed a web-based sepsis registry system ("Korean Registry for Improving Sepsis Survival" [KISS]) protocol to be used in hospitals in the Korea for evaluation of the epidemiology and clinical characteristics of patients with sepsis, via an analysis of outcome predictors.

Leptospirosis is a widespread worldwide zoonosis. Human leptospirosis was first identified in the Korea in 1984 as the cause of "epidemic pulmonary hemorrhagic fever of unknown etiology" that occurred sporadically or in outbreaks. The major outbreaks, leading to some deaths, mainly involved rice field farmers who worked in wet and muddy rice paddies following floods or heavy rainfalls.

Background: While herd effects and serotype replacement by childhood pneumococcal protein conjugated vaccines (PCVs) continues to accumulate worldwide, direct effectiveness of 23-valent pneumococcal polysaccharide vaccine (PPV23) against pneumococcal diseases in the elderly has been challenged. We estimated the direct effectiveness of PPV23 in the elderly population.

Methods: For a hospital-based case-control study, cases of invasive pneumococcal disease (IPD) and non-bacteremic pneumococcal pneumonia (NBPP) (adults ≥ 65 years) were identified in 14 hospitals participated in the pneumococcal surveillance program from March 2013 to October 2015, following implementation of PPV23 national immunization program (NIP) for the elderly in the Republic of Korea.
