[Renal acidification disturbance in vitamin D deficiency (author's transl)].
Extensive studies of renal acidification process have been performed in states of vitamin D deficiency. Results show that the process of hydrogen ion excretion is strongly impaired on the entire length of the nephron. Vitamin D and parathyroid hormone probably interfere within tubular cells regulating the concentration of calcium and cyclic AMP; the modification of such an equilibrium carried out by vitamin D deficiency would explain the renal dysfunction.
