Proximal renal tubular acidosis (proximal RTA) in the paediatric population presents distinct clinical concerns compared with adult disease. Children face higher risks of impaired skeletal development and growth retardation, making timely and appropriately dosed management essential.
This protocol addresses proximal RTA specifically in children, where the metabolic demands of active growth mean that the approach to correction differs substantially from adult management. The priorities centre on protecting bone health and supporting normal growth trajectories.
Children with proximal RTA often require aggressive alkali therapy (5–15 mmol/kg/day) to mitigate bone disease and growth retardation, whereas alkali therapy is typically administered in adults with serum HCO3– concentrations of less than 18 mmol/L to prevent severe acidosis.
