Cardiovascular disease (CVD) is the main cause of mortality among chronic kidney disease (CKD) patients, both in adults and in children. Hypertension is one of the risk factors of CVD. For early detection of subclinical CVD in pediatric CKD, 24 h ambulatory blood pressure monitoring (ABPM), cardiosonography, and arterial stiffness assessment were evaluated. CAKUT (congenital anomalies of the kidney and urinary tract) are the main etiologies of pediatric CKD. Previously, by a proteomic approach, we identified complement factor H (CFH) and related proteins differentially expressed between children with CAKUT and non-CAKUT CKD. In this study, we aimed to evaluate whether CFH, CFH-related protein-2 (CFHR2), and CFH-related protein-3 (CFHR3) were related to CVD risk in children with CKD. This study included 102 subjects aged 6 to 18 years old. The non-CAKUT group had higher plasma CFHR3 levels than the CAKUT group (p = 0.046). CFHR3 was negatively correlated with LV mass (p = 0.009). CFHR2 was higher in children with CKD with 24 h hypertension in the ABPM profile (p < 0.05). In addition, children with non-CAKUT CKD with day-time hypertension (p = 0.036) and increased BP load (p = 0.018) displayed a lower plasma CFHR3 level. Our results highlight that CFH and related proteins play a role for CVD in children with CKD. Early assessment of CFH, CFHR2, and CFHR3 may have clinical utility in discriminating CV risk in children with CKD with different etiologies.

Obesity is a rapidly growing health problem worldwide, affecting both adults and children and increasing the risk of chronic diseases such as type 2 diabetes, hypertension and cardiovascular disease (CVD). In addition, obesity is closely linked to chronic kidney disease (CKD) by either exacerbating diabetic complications or directly causing kidney damage. Obesity-related CKD is characterized by proteinuria, lipid accumulation, fibrosis and glomerulosclerosis, which can gradually impair kidney function.

Background: We investigated factors associated with post-transplant growth in pediatric kidney transplant (KTx) recipients with a focus on plasma bicarbonate (HCO3) and estimated the effect of alkali treatment on growth.
Methods: In this study of the CERTAIN Registry, data were collected up to 5 years post-transplant. Generalized Additive Mixed Models were applied to assess the association between post-transplant growth and covariates.

Background: Chronic kidney disease (CKD) is a burden on children and their caregivers, especially in advanced stages requiring different renal replacement modalities (peritoneal/hemodialysis and renal transplant). The aim of the study is to measure the health-related quality of life (HRQOL) of children and their caregivers for each renal replacement modality, specifically dialysis and transplant.
Methods: This study is a single-center cross-sectional study that was carried out at King Fahad Specialist Hospital in Dammam (KFSH-D).

Background: Chronic kidney disease (CKD) is a prevalent global health issue affecting millions of patients worldwide, impacting quality of life, impeding physical and psychological well-being, causing financial stress, and increasing mortality rates. This study aimed to highlight the prevalence of CKD and its associated risk factors across Saudi Arabia.
Method: This is a cross-sectional study conducted from 2015 to 2022, using data from 42 branches of a major network of diagnostic laboratories in Saudi Arabia, covering the country's 13 administrative areas.
