VAIs in CKD Patients on Dialysis: Low Incidence
Okay, here’s a breakdown of the provided text, summarizing the key information about vascular Access Infections (VAIs) in Chronic Kidney Disease (CKD) patients in Japan:
Main Topic: The epidemiology and risk factors for Vascular Access Infections (vais) in patients with Chronic Kidney Disease (CKD) undergoing hemodialysis in Japan.
Key Findings:
* CKD & VAI Susceptibility: Patients with CKD, especially those on hemodialysis, are more prone to infectious diseases, including VAIs.
* Study Methodology: Researchers in Japan used a voluntary surveillance network (DSN-J) to collect data from 52 hospitals between January 2008 and December 2023, analyzing over 5.9 million dialysis sessions.
* Overall Incidence: The overall incidence of VAI was 0.23 per 1000 dialysis sessions. This incidence has been decreasing over time.
* Access Type & Risk:
* Non-cuffed catheters (NCCs) carried the highest risk of VAI (7.75 per 1000 sessions, accounting for 663 infections). This was significantly higher than all other access types:
* Arteriovenous fistula (AVF): 0.05
* Superficialization of brachial artery: 0.10
* Arteriovenous graft: 0.49
* Cuffed catheter (CC): 1.39
* Dominant Pathogens:
* Staphylococcus aureus (methicillin-susceptible) was the most common cause of VAIs (306 cases).
* Methicillin-resistant staphylococcus aureus (MRSA) was also meaningful (227 cases).
* Diabetes & Risk: Patients with CKD and diabetes had a significantly higher risk of VAI when using NCCs (RR 1.24). this increased risk was not observed with cuffed catheters.
* Femoral Site: NCCs inserted at the femoral site had a significantly higher risk (the text cuts off here, but implies this is a negative finding).
Background Information (about CKD):
* CKD is a gradual loss of kidney function.
* Kidneys filter waste and fluids.
* Advanced CKD can lead to dangerous build-up of toxins.
* End-stage kidney failure requires dialysis or a transplant.
* Treatment focuses on slowing progression, but damage may continue even with treatment.
