Calcium metabolism was studied prospectively in 12 patients with amyotrophic lateral sclerosis. Two patients showed mild hypocalcemia, malabsorption of calcium, and elevated plasma parathyroid hormone concentrations. Serum 25-hydroxyvitamin D was decreased in one and low-normal in the second. These two patients and a third showed aminoaciduria on thin layer chromatography. Calcium metabolism was apparently restored to normal by dihydrotachysterol, a vitamin D analog, but no improvement in neurologic function resulted. Bone radiographs taken in search of metabolic bone disease showed a significant increase in the incidence of congenital vertebral anomalies in the ALS patients (50% versus 8%). The relationship of the abnormalities in calcium metabolism and in vertebral structure to the etiology of motor neuron disease is not known.
