연구실 소개

구남수 교수의 연구실은 중증 감염, 특히 세균성 패혈성 쇼크와 다제내성 병원성 박테리아에 의한 감염에서의 생존 예측 및 치료 전략 개발을 핵심으로 합니다. 특히, 혈액 검사 지표인 CRP, 알부민, RDW 등이 패혈성 쇼크 환자의 180일 사망 예측에 어떻게 기여하는지 분석하며, 다제내성 아세티노박터 바우마니아 및 스테노트로포모나 말토필리아 등의 병원성 세균에 대한 신약 조합 치료의 효과를 동물 모델을 활용해 평가하고 있습니다. 또한 항생제 관련 부작용의 발생 원인과 영향을 분석하여 임상적 안전성을 높이기 위한 연구도 진행 중입니다.

SJR Q1PLoS ONEOA

BACKGROUND: Sepsis, including severe sepsis and septic shock, is a major cause of morbidity and mortality. Albumin and C-reactive protein (CRP) are considered as good diagnostic markers for sepsis. Thus, initial CRP and albumin levels were combined to ascertain their value as an independent predictor of 180-day mortality in patients with severe sepsis and septic shock. MATERIALS AND METHODS: We conducted a retrospective cohort study involving 670 patients (>18 years old) who were admitted to the

SJR Q1Shock

Red blood cell distribution width (RDW) is known to be a predictor of severe morbidity and mortality in some chronic diseases such as congestive heart failure. However, to our knowledge, little is known about RDW as a predictor of mortality in patients with Gram-negative bacteremia, a major nosocomial cause of intra-abdominal infections, urinary tract infections, and primary bacteremia. Therefore, we investigated whether RDW is an independent predictor of mortality in patients with Gram-negative

Stenotrophomonas maltophilia is a nosocomial pathogen associated with high morbidity and mortality, particularly in immunocompromised or critically ill patients. In this study, we investigated the risk factors for mortality in patients with S. maltophilia bacteremia.Retrospectively, medical records from all patients with S. maltophilia bacteremia between December 2005 and 2014 at Severance Hospital, a 2000-bed tertiary care hospital in Seoul, Korea, were reviewed.

SJR Q1Scientific ReportsOA

Unfortunately, the options for treating multidrug-resistant (MDR) Acinetobacter baumannii (A. baumannii) infections are extremely limited. Recently, fosfomycin and minocycline were newly introduced as a treatment option for MDR A. baumannii infection. Therefore, we investigated the efficacy of the combination of colistin with fosfomycin and minocycline, respectively, as therapeutic options in MDR A. baumannii pneumonia. We examined a carbapenem-resistant A. baumannii isolated from clinical speci

SJR Q1Scientific ReportsOA

Abstract Only a few observational studies investigated the association between hypochloremia and mortality in critically ill patients, and these studies included small number of septic patients. Also, no study has evaluated the effect of an increase in chloride (Cl − ) concentration in hypochloremia on the mortality. A total of 843 Korean septic patients were divided into three groups based on their baseline Cl − level, and Cox analyses were performed to evaluate the 28-day mortality. Moreover,

SJR Q2BioMed Research InternationalOA

BACKGROUND: Adverse drug reactions (ADRs) are any unwanted/uncomfortable effects from medication resulting in physical, mental, and functional injuries. Antibiotics account for up to 40.9% of ADRs and are associated with several serious outcomes. However, few reports on ADRs have evaluated only antimicrobial agents. In this study, we investigated antibiotic-related ADRs at a tertiary care hospital in South Korea. METHODS: This is a retrospective cohort study that evaluated ADRs to antibiotics th

SJR Q1HIV MedicineOA

OBJECTIVES: HIV-associated neurocognitive disorder (HAND) is an independent predictor of early mortality and is associated with many difficulties in activities of daily living. We sought to determine the prevalence of and risk factors for HAND in HIV-infected Koreans. In addition, we investigated the performance of screening tools and components of neuropsychological (NP) tests for diagnosing HAND.

In this study, the sensitivity of the GMA for the diagnosis of IA was very low in non-haematological patients. Although the GMA test is considered useful for the diagnosis of IA in haematological patients, it had low diagnostic value for IA in non-haematological patients.

SJR Q1Journal of Intensive Care MedicineOA

Purpose: The purpose of our study was to investigate whether a simple scoring system based on the red blood cell distribution width (RDW), delta neutrophil index (DNI), and platelet count was associated with the prognosis of patients with sepsis, and whether this scoring system was more useful than each individual parameter. Materials and Methods: We conducted a retrospective cohort study involving adult patients who received intensive therapy due to severe sepsis and septic shock from January 2

SJR Q1Journal of Cachexia Sarcopenia and MuscleOA

BACKGROUND: Despite medical advances, septic shock remains one of the main causes of high mortality in critically ill patients. Although sarcopenia is considered a predictor of mortality in septic shock patients, most studies have only investigated short-term mortality, and those on long-term prognosis are limited. We investigated the impact of sarcopenia on long-term mortality in a large patient population with septic shock. METHODS: A retrospective cohort study comprising 905 patients with sep

SJR Q1BMC Infectious DiseasesOA

BACKGROUNDS: Several studies have evaluated the impact of matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry (MS) combined with antimicrobial stewardship in patients with positive blood cultures; clinical outcomes improved. However, in many hospitals, antimicrobial stewardship is not available because of restricted medical resources. Thus, we investigated the impact of evaluation by MALDI-TOF MS on the clinical outcomes of patients with bacteremia and fungem
