Treatment of Proximal Renal Tubular Acidosis in Patients on Ongoing Alkali Therapy

Clinical Scenario

This protocol targets proximal renal tubular acidosis in patients already receiving alkali therapy. The clinical focus is on optimising bicarbonate handling and maintaining electrolyte balance within that treatment context.

Treatment Approach — Partial Overview

The approach involves adding a thiazide diuretic to the existing alkali regimen to support bicarbonate reabsorption, combined with measures directed at potassium balance. The complete clinical algorithm, decision points, and monitoring guidance are available in the full protocol.

Hydrochlorothiazide may be beneficial in increasing HCO3– reabsorption capacity, preventing volume expansion, and increasing the effectiveness of alkali therapy; however, supplemental K+ or K+-sparing diuretics are needed to prevent hypokalemia.
