To date, no study has precisely investigated the impact of carbapenem resistance in K. pneumoniae (CRKP) BSI on mortality. METHODS: This retrospective study included 87 patients with CRKP BSI and 321 patients with carbapenem-susceptible K. pneumoniae (CSKP) BSI from 2015 to 2020. Propensity score analyses with stabilized inverse probability of treatment weighting (IPTW-S) was applied to balance covariates...

INTRODUCTION: Peritoneal dialysis (PD)-associated peritonitis due to tuberculosis (TB) is associated with poor outcomes and optimal treatment strategies for this condition remain unknown. Our study aimed to: (i) systematically review the published literature on peritonitis caused by Mycobacterium tuberculosis in patients on PD and (ii) review cases of peritonitis due to M tuberculosis in patients on PD reported in Australia and New Zealand to determine the epidemiology, management strategies, and outcomes of this condition...

BACKGROUND: Central catheter-related bloodstream infections (CRBIs) can lead to severe complications, including suppurative thrombophlebitis, endocarditis, and metastatic infections. While complications due to CRBIs caused by Staphylococcus aureus (SA) are well-known, there are limited data regarding CRBIs caused by other bacteria. METHODS: This 2-year retrospective single-center study of patients with CRBIs from a tertiary care hospital examined the hematogenous complications associated with CRBIs according to patient characteristics, central venous catheter (CVC) types, and causative bacteria...

BACKGROUND: Pantoea agglomerans is an environmental pathogen known to cause infection in immunocompromised individuals, particularly after thorn injuries. However, previous data showed few cases of human disease caused by contaminated medical products such as parenteral nutrition, anesthetic agents, blood, and peritoneal dialysis solutions. Infection in hemodialysis patients is rare. In this study, we presented a detailed account of several hemodialysis patients infected with this contagious pathogen and compared them with noninfected dialysis patients...

BACKGROUND: Candida is one of the most important pathogens of hospital-acquired bloodstream infections. Its morbidity and mortality are still high, which is a serious global public problem.

The present study is the first report that aims to evaluate the epidemiological characteristics, causes, and dialysis-related factors associated with readmissions in ESRD patients who were going to routine hemodialysis. Patients and methods: This cross-sectional observational study enrolled 208 patients with ESRD...

INTRODUCTION: Staphylococcus aureus is a successful pathogen in hospital and community. Hemodialysis patients have high colonization rates. Interactions between them and their household contacts, are an opportunity to understand the S. aureus colonization between hospitals and community. This study aims to determine the clinical and epidemiological characteristics of S. aureus colonization in hemodialysis patients and their household contacts, as well as the genetic relationship between their isolates...

Patients in hemodialysis on central venous catheter as vascular access are at risk of infections. Catheter-related bloodstream infection is one of the most serious catheter-complications in hemodialysis patients. Its clinical and microbiological diagnosis is challenging. The implementation of empiric antibiotic therapy is based on old recommendations proposing the combination of a molecule targeting methicillin-resistant Staphylococcus aureus and a betalactamin active on P. aeruginosa, and also adapting this probabilistic treatment by carrying out a microbiological register on a local scale, which is rarely done...

RATIONALE & OBJECTIVE: Infections cause significant morbidity and mortality for children receiving maintenance hemodialysis (HD). The Standardizing Care to Improve Outcomes in Pediatric End-Stage Kidney Disease (SCOPE) Collaborative is a quality-improvement initiative aimed at reducing dialysis-associated infections by implementing standardized care practices. This study describes patient-level risk factors for catheter-associated bloodstream infections (CA-BSIs) and examines the association between dialysis center-level compliance with standardized practices and risk of CA-BSI...

RATIONALE & OBJECTIVE: Staphylococcus aureus (Saureus) bacteremia (SAB) is associated with morbidity and mortality in patients receiving maintenance hemodialysis (HD). We evaluated changes in clinical and bacterial characteristics, and their associations with clinical outcomes with SAB in this population over a 21-year period. STUDY DESIGN: Prospective cohort study. SETTING & PARTICIPANTS: 453 hospitalized, non-neutropenic adults receiving maintenance HD who developed monomicrobial SAB between 1995 and 2015...

BACKGROUND: Infective endocarditis (IE) is a rare complication following solid organ transplant (SOT); data on the clinical features and outcomes of IE in SOT recipients in the modern era are limited. METHODS: We conducted a single-center retrospective cohort study of IE diagnosed from 1/2008-12/2014 in SOT recipients, who were matched by age and microorganism to cases of IE in non-SOT, to describe the clinical features and outcomes. RESULTS: There were 14 cases of IE identified in SOT recipients matched to 56 non-SOT controls...

INTRODUCTION: The incidence of catheter-related bloodstream infections (CRBSI) ranges from 2.2 to 5.5 episodes per 1,000 catheter-days. Our aim was to evaluate the utility of a generalized and prolonged gentamicin-lock therapy in patients undergoing hemodialysis (HD) in a third-level hospital for the reduction in CRBSI. METHODS: A prospective cohort analyzed before and after intervention. During intervention periods after each HD-session, the catheter lumens were locked with gentamicin/heparin for all patients compared to nonintervention periods were the same procedure was performed without gentamicin...

OBJECTIVES: Methicillin-resistant Staphylococcus aureus (MRSA) infections in the hemodialysis (HD) population are epidemiologically classified as healthcare-associated infections. The data about the clinical impact and bacterial characteristics of hospital-onset (HO)- and community-onset (CO)-MRSA in HD patients are scarce. The current study analyzed the difference in the clinical and molecular characteristics of HO-MRSA and CO-MRSA. METHODS: We performed a retrospective review and molecular analysis of clinical isolates from 106 HD patients with MRSA bacteremia from 2009 to 2014...

STUDY DESIGN: A retrospective study of patients who were hospitalized for infectious spondylodiscitis over a 13-year period. OBJECTIVE: To elucidate the epidemiology and prognostic factors of infectious spondylodiscitis in hemodialysis (HD) patients and to identify the impact of HD on infectious spondylodiscitis. SUMMARY OF BACKGROUND DATA: Only a few case studies of infectious spondylodiscitis in HD patients can be found in the literature...

Hemodialysis catheters are associated with higher risks of complications compared to arteriovenous fistulas and grafts. Some common complications of dialysis catheters include infection, thrombus formation, central venous stenosis, and mechanical dysfunction. Rarely, catheters can become firmly adhered to a vessel wall. Catheter adhesion is a serious complication that can impact the delivery of safe and effective dialysis to affected patients. Adherent catheters commonly present insidiously with no overt diagnostic signs and symptoms or antecedent catheter malfunction...

Cryptococcosis is a lethal fungal infection mainly caused by Cryptococcus neoformans/C. gattii species. Currently, our understanding of cryptococcosis episodes in HIV-negative patients during renal dialysis remains scarce and fragmented. Here, we performed an analysis of pooled cases to systemically summarize the epidemiology and clinical characteristics of cryptococcosis among HIV-negative patients with renal dialysis. Using pooled data from our hospital and studies identified in four medical databases, 18 cases were identified and analyzed...

BACKGROUND AND OBJECTIVES: Persons receiving outpatient hemodialysis are at risk for bloodstream and vascular access infections.
