Understanding Blood Pressure and Kidney Function in Children with Sickle Cell Anemia

Introduction: Sickle cell anemia (SCA) is a severe genetic blood disorder affecting millions worldwide, particularly in regions with high prevalence rates of the sickle cell gene. Among its numerous complications, renal (kidney) dysfunction is a major concern. A recent study conducted at Ekiti State University Teaching Hospital, Nigeria, investigates the patterns of blood pressure and kidney function in children diagnosed with SCA. Understanding these findings can contribute to early detection and management, ultimately improving patient outcomes.

Key Findings of the Study:

• The study involved 51 children aged 2-16 years diagnosed with SCA.
• Prevalence of Renal Impairment: 27.5% of participants had impaired kidney function, defined as an estimated glomerular filtration rate (eGFR) below 90mL/min/1.73m2.
• Blood Pressure Observations Most participants had blood pressure readings below the 50th percentile for their age and gender, aligning with previous research indicating lower blood pressure in SCA patients.
• Proteinuria and Kidney Damage: 11.8% of children exhibited proteinuria (protein in urine), a possible early sign of kidney disease progression.
• Glomerular Hyperfiltration Older children (≥14 years) showed elevated eGFR levels, suggesting early kidney damage and compensatory hyperfiltration.

Medical Insights on Kidney Function in SCA According to the National Kidney Foundation, early-stage kidney disease often progresses unnoticed in SCA patients. The presence of proteinuria and glomerular hyperfiltration highlights the importance of regular kidney function screening in affected children. Early interventions, including hydration, blood pressure control, and tailored medical treatments, are crucial for delaying progression to chronic kidney disease (CKD).

The Importance of Early Diagnosis and Management

• Routine screening for kidney function and blood pressure should be standard in SCA management.
• Parents and caregivers must be educated on symptoms of kidney dysfunction, including swelling, fatigue, and changes in urine output.
• More resources should be allocated for newborn screening programs to enable early diagnosis and treatment.
