Sleep‐related breathing disorders and cardiometabolic risk factors in pediatric kidney transplant recipients

Abstract

Background SRBDs have been shown to increase the risk of cardiovascular disease, which is a significant cause of mortality in kidney transplant recipients. Few studies have investigated the association between SRBDs and cardiometabolic risk factors in pediatric kidney transplant recipients. Methods This was a cross‐sectional study of pediatric kidney transplant recipients using baseline cardiometabolic data from a previous clinical trial (NCT01007994). Parents/guardians of pediatric kidney transplant recipients filled out 22‐item PSQ. A score greater than 33% was defined as a diagnosis of a SRBD. Fisher's exact test, Mann–Whitney U test, and regressions were used to determine associations. Results Among the 58 transplant recipients enrolled, 14.80% (n = 8) of participants identified as Black and 40.7% (n = 22) were male. The median age was 13 (IQR 8.25, 17) years and median number of years post‐transplant for participants was 2 (IQR 1, 4). The prevalence of SRBDs was 26% (n = 14). The presence of a SRBD was associated with abnormalities in multiple cardiometabolic risk factors including total cholesterol level (β = 23.63; 95% CI 3.58–43.67), LDL level (β = 24.94; 95% CI 6.37–43.50), triglyceride level (β = 54.62; 95% CI 8.74–100.50), and LVH (OR = 5.12; 95% CI 1.12–23.45) when adjusted for age, sex, and race. Conclusions Similar to associations reported in the general pediatric and general CKD populations, SRBD is associated with increased cardiometabolic risk in pediatric kidney transplant recipients.

Fatigue and Quality of Life in Children with Chronic Kidney Disease

“…Similar data are limited in pediatric patients. According to a recent study, sleep-related breathing disorders were remarked in 26% of pediatric kidney-transplant recipients, and were associated with cardiometabolic risk factors, including altered lipid profiles and left ventricular hypertrophy [ 30 ]. Conclusively, our results highlight that attention should be paid for the evaluation of sleep disturbances in both CKD 5D and KTx patients, and further studies are required to explore the triggering factors in both patient groups.…”
