In a sibship, 4 out of 5 children featured pseudo-hypoparathyroidism. The following points were verified: hypocalcaemia; increase of the serum level of PTH; normal response of bone and gut effectors to endegenous PTH; contrast between normal bone X-rays and lesions detected by histological studies.

Proximal renal tubular acidosis in vitamin D deficiency rickets.

A proximal renal tubular acidosis (RTA) is the mechanism underlying the systemic acidosis found in vitamin D deficiency rickets. Acidotic subjects have high levels of PTH. In non-acidotic subjects proximal bicarbonate wasting can be induced by exogenous PTH injection. Carbonic anhydrase activity is not involved in this process. Calcium infusion is able to suppress both the spontaneous and the PTH-induced bicarbonate leak. The development of RTA in vitamin D deficiency is related to a particular equilibrium between two antagonizing factors at tubular level, parathyroid hormone and calcium.

[Acute myeloblastosis in von Jaksch-Luzet syndrome].

A 7 month-old infant of Italian origin, who was given a vitamin-D deficient diet developed a Von Jaksch-Luzet syndrome with more than 20% myeloblasts in the bone marrow. Plasma levels of vitamin D metabolites wer low and parathormone levels were high. A low dose of vitamin D3 (2,000 IU cholecalciferol/day) resulted in the recovery of a normal phosphocalcic balance and in the disappearance of myeloblastosis.
