AI Article Synopsis
- This study examined bacteremia in patients who underwent simultaneous pancreas-kidney transplantation (SPKT), focusing on the types of microorganisms found in blood and catheter samples.
- Out of 66 samples collected from 26 patients, the majority of microbial isolates were Gram-positive bacteria (73.9%), particularly staphylococci, with a smaller presence of Gram-negative bacteria and yeast-like fungi.
- The findings highlight a concerning trend of multi-drug-resistant strains, possibly linked to the frequent use of antibiotics for infection prevention in these transplant patients.
Article Abstract
Background: Bacteremia is among the known complications in simultaneous pancreas-kidney transplantation (SPKT). This study evaluated the frequency of microbial isolates and their susceptibility profiles among cultures of clinical samples obtained from blood and from the tips of blood vessel catheters of 26 SPKT recipients suspected of bacteremia in the early posttransplant period.
Patients And Methods: Data on microbiologic blood cultures of 26 adult patients undergoing SPKT were collected prospectively from 2001 to the end of 2006. The isolation and identification of cultured microorganisms were performed according to standard microbiological procedures and commercially available tests. The susceptibility of the strains to antibacterial agents was established by the Clinical and Laboratory Standards Institute guidelines.
Results: All patients were followed prospectively for the first 4 weeks after surgery. Among 66 clinical samples, there were 23 microbial isolates from blood samples of 17 recipients and catheter tips of 12 recipients. The most common isolates were Gram-positive bacteria (73.9%) with domination of staphylococci (64.7%) and MRCNS strains (81.8%). Gram-negative bacteria comprised 17.4% of positive cultures, whereas yeast-like fungi, 8.7% with a predominance of Candida glabrata.
Conclusion: Our study showed predominately Gram-positive bacteria in 73.9% of isolates. The increased proportion of multi-drug-resistant bacteria and fungi to antimicrobial agents may be due to the frequent use of these agents for prophylaxis of bacterial infections in patients.

Impact of vancomycin area under the curve in early or later phase on efficacy and nephrotoxicity in patients with enterococcal bloodstream infections: a multicenter study.

Department of Pharmaceutical Care, Faculty of Pharmacy, Silpakorn University, Nakhon Pathom, 73000, Thailand.
Background: The optimal pharmacokinetic and pharmacodynamic (PK/PD) parameters of vancomycin that can improve outcomes in enterococcal infections remain controversial. To clarify the therapeutic target for this antibiotic, this study aimed to determine vancomycin PK/PD parameters associated with efficacy in the early (during 72 h) or later (after 72 h) phase of treatment and nephrotoxicity in enterococcal bloodstream infection patients.
Methods: This multicenter retrospective study reviewed medical records of patients with enterococcal bloodstream infections treated with intravenous vancomycin infusion for at least 72 h between January 2016 and March 2024 at Phramongkutklao Hospital or Nopparatrajathanee Hospital in Bangkok, and Rachaburi Hospital in Rachaburi Province, Thailand.

Background/purpose: Early detection of severe dengue (SD) and appropriate management are crucial in reducing the case fatality rate. The objective of this study was to investigate the clinical characteristics of SD and identify independent risk factors associated with mortality among SD patients.
Methods: A retrospective study was conducted at two medical center hospitals between 2002 and 2019, involving patients aged ≧18 years with laboratory-confirmed SD.

Department of Medical Ultrasonics, the First Affiliated Hospital of Sun Yat-Sen University, Guangzhou, China.
Background: Transcatheter valve-in-valve replacement (TMViVR) is an alternative option for patients with bioprosthetic valve failure (BVF) who are at high surgical risk. Although infective endocarditis (IE) after transcatheter mitral valve-in-valve replacement is unusual, it is associated with significantly high mortality.
Case Presentation: An 81-year-old male patient was admitted with intermittent thoracic tightness, chest pain persisting for 3 years, and shortness of breath with nausea for 1 week.

Thoracic aortic pseudoaneurysms are a rare but serious complication of infectious processes, often resulting from mycotic (infectious) aneurysms, occurring when the vessel wall is compromised by an infection, leading to the formation of a pseudoaneurysm [1]. Mycotic aneurysms typically result from bacteremia or fungemia, with common sources being infective endocarditis or other systemic infections. Tuberculosis, though a common infectious disease worldwide, is an unusual cause of aortic pseudoaneurysm formation.

Objectives: Antibacterial-resistant gram-negative hospital-acquired infections result in significant morbidity and mortality. In clinical trials, ceftolozane/tazobactam (C/T) has been effective against these infections; however, real-world findings are limited.
Methods: SPECTRA was a global, retrospective, observational inpatient study of adults treated with C/T for ≥48 hours, conducted between 2016 and 2020.
