Hypophosphatemic rickets developed after treatment with etidronate disodium in a patient with generalized arterial calcification in infancy

Ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) was originally reported as a responsible gene for generalized arterial calcification in infancy (GACI). Though the prognosis of GACI patients is poor because of myocardial infarction and heart failure in relation to medial calcification of the coronary arteries, some patients rescued by bisphosphonate treatment have been reported. Recen...

Effects of etidronate on the Enpp1−/− mouse model of generalized arterial calcification of infancy

Generalized arterial calcification of infancy (GACI) is an autosomal recessive disorder of spontaneous infantile arterial and periarticular calcification which is attributed to mutations in the ectonucleotide pyrophosphatase/phosphodiesterase 1 (Enpp1) gene. Whilst the bisphosphonate, etidronate, is currently used off-label for the treatment for GACI, recent studies have highlighted its detrime...

Tertiary hyperparathyroidism in a patient with X-linked hypophosphatemic rickets.

A 29-year-old female (Weight=50 kg, Height=152 cm, Body Mass Index= 21.6 Kg/m, target height: 151.5 cm) with symptomatic XLHR (X-linked Hypophosphatemic Rickets) since childhood was referred for evaluation of hypercalcemia. At the age of three years, during evaluation for growth retardation and features of rickets along with hypophosphatemia, she received the diagnosis of XLHR. Family history w...

Type 1 Tyrosinemia with Hypophosphatemic Rickets; a Case Report

Background: Tyrosinemia type 1 is an autosomal recessive metabolic disorder, which typically affects liver and kidneys. It is caused by a defect in fumarylacetoacetate hydrolase or fumarylacetoacetase (FAH) enzyme, the final enzyme in the tyrosine degradation pathway. The disease typically manifests as early onset type in early infancy with acute hepatic crisis with hepatomegaly and bleeding te...
