Preexisting comorbidities are associated with the mortality rate as well as the predialysis adverse events in incident dialysis patients

Impact of risk factors on the incidence of tunneled dialysis catheter infections: a systematic review and meta-analysis

INTRODUCTION

Tunneled dialysis catheters (TDCs) are important for hemodialysis in patients awaiting a permanent surgical solution, kidney transplantation or without feasible surgical access. Infection of a TDC is a common and severe complication, which often requires removal of the TDC and causes high morbidity and mortality. To date, several risk factors for TDC infections have been reported. This systematic review and meta-analysis aim to provide an overview of currently known risk factors.

METHODS

A systematic literature search was conducted, including all studies describing patient-, catheter-, and dialysis-related risk factors for TDC infections. In case sufficient data was available for a risk factor, a meta-analysis with random effects model was performed.

RESULTS

Out of 1273 studies, 30 were included describing a total of 71 risk factors. A meta-analysis was conducted for 26 risk factors. The average incidence of TDC infections was 1.16 ± 0.70/1000 catheter days. Diabetes (odds ratio, OR 1.96), coronary artery disease (OR 2.16), peripheral artery disease (OR 2.28), history of sepsis (OR 2.79), and the number of prior TDCs (OR 1.24) were the most significant risk factors for infection.

CONCLUSION

Several risk factors are associated with increased TDC infection rates. Most of these risk factors are also linked with infection in other populations and most likely reflect the general frailty of hemodialysis patients. The association between many risk factors and TDC infections was often unclear due to the low number of studies available. Additional large cohort studies are necessary to demonstrate the relevance of these risk factors.

Hemodialysis-Related Pericarditis With Cardiac Tamponade

Pericarditis can cause chest symptoms in dialysis patients. Moreover, it tends to present with various symptoms other than chest pain in patients with end-stage renal disease (ESRD) than in non-ESRD patients. Here, we present the case of an 86-year-old man on maintenance dialysis who was admitted to the hospital with chest discomfort and dyspnea, which led to cardiac tamponade due to unexplained pericardial effusion. The patient underwent pericardial drainage with an epigastric approach. Based on his medical history and pericardial fluid examination, his condition was diagnosed as dialysis-related pericarditis. Non-steroidal anti-inflammatory drugs and prednisolone administration improved the patient’s condition. There are various causes of pericarditis in patients undergoing hemodialysis. It is crucial to examine the patient’s clinical presentation and pericardial fluid volume to clarify the cause of the disease.
