Popis: Proximal renal tubular acidosis (pRTA) is a rare disorder. Hypokalemia may be associated with it; occasionally leading to features like hypokalemic periodic paralysis. Though pRTA is a tubulointerstitial kidney disease, glomerulonephritis may occasionally lead to pRTA by tubular damage through leaking proteins, cytokines or by inflammatory infiltrates. In our reported case a 27 year old male had recurrent episodes of hypokalemic quadriparesis. Investigations revealed features of pRTA including hypokalemia and non-anion-gap hyperchloremic metabolic acidosis. His urine pH dropped to 5 with NH4Cl loading test. Kidney biopsy showed membranoproliferative glomerulonephritis with tubulointerstitial damage. Hypokalemic periodic paralysis and pRTA are uncommon associations of membranoproliferative glomerulonephritis.
