Hypertension in hemodialyzed children

Area of Science:

• Pediatric Nephrology
• Cardiovascular Health in CKD
• Dialysis Management

Background:

• Hypertension (HTN) is a frequent complication in pediatric chronic kidney disease (CKD).
• Dialysis-related HTN is often linked to fluid overload, manageable with improved fluid and salt balance.
• Understanding HTN prevalence and contributing factors in children on hemodialysis (HD) is crucial.

Purpose of the Study:

• To determine the prevalence of hypertension among pediatric patients undergoing maintenance hemodialysis.
• To investigate the correlation between hypertension and various demographic and clinical factors in this population.

Main Methods:

• A prospective study involving forty pediatric patients with CKD on maintenance HD across three Baghdad centers.
• Hypertension defined as blood pressure (BP) at or above the 95th percentile for age, height, and sex, or current use of antihypertensive medication.
• Data collected on patient demographics, CKD etiology, HD parameters, and serum albumin levels.

Main Results:

• Hypertension was prevalent in 67.5% (27/40) of pediatric HD patients.
• No significant correlation was found between HTN and gender, age, CKD etiology, HD session duration, frequency, total duration, or blood flow rate.
• Serum albumin levels demonstrated a significant correlation with blood pressure.

Conclusions:

• A high prevalence of hypertension exists in pediatric patients on hemodialysis.
• Serum albumin level is a significant correlating factor for hypertension in this cohort.
• Further research into managing fluid balance and nutritional status (serum albumin) is warranted for controlling HTN in pediatric CKD patients on HD.
