Pre-transplant diabetes significantly increases the risk of urinary tract infections (UTIs) after kidney transplantation. Post-transplant diabetes mellitus also elevates UTI risk in these patients.
Area of Science:
- Nephrology
- Transplantation Immunology
- Infectious Diseases
Background:
- Urinary tract infections (UTIs) are a frequent complication following kidney transplantation.
- Diabetes mellitus, both pre-existing and post-transplant, may influence UTI development in kidney transplant recipients.
Purpose of the Study:
- To assess the impact of pre-existing diabetes mellitus and post-transplant diabetes mellitus (PTDM) on the incidence of pyelonephritis in kidney transplant recipients.
- To identify risk factors associated with UTIs in kidney transplant recipients.
Main Methods:
- Retrospective analysis of 299 adult kidney transplant recipients from 2018-2022.
- Patients classified into three groups: pre-transplantation diabetics, PTDM, and non-diabetics.
- Exclusion of asymptomatic bacteriuria and lower UTIs.
Main Results:
- A total of 100 UTIs occurred during a median follow-up of 31 months.
- Cumulative UTI incidence at 48 months was 34.9% (no diabetes), 56% (pre-transplant diabetes), and 47.3% (PTDM).
- Pre-transplant diabetes independently associated with a 79% increased UTI risk (aHR=1.79); female gender increased risk by 85%.
Conclusions:
- Pre-transplant diabetes mellitus is a significant risk factor for developing UTIs post-kidney transplantation.
- PTDM also contributes to increased UTI risk, though pre-transplant diabetes shows a stronger independent association.
