title: [Aspects of phosphorus and carbohydrate metabolism in amyotrophic lateral sclerosis].
abstract: The behaviour of glycaemia, insulinaemia, phosphoraemia, somatotropinaemia,free glycerol and triglyceridaemia was studied in six patients with A.L.S. following sugar load (1 g/Kg) in fasting. The results of glycaemia and insulinaemia were in tune with published data which have pointed to reduced sugar tolerance and reduced insulin secretion in patients with A.L.S. In the present experiments, particularly significant were the phosphoraemia responses. The failure of inorganic phosphorus values to fall after glucose loading suggests that the glycidic intolerance of these patients is related above all to a reduction in functioning muscular mass rather than to insufficient insulin secretion. The reduction in nervous tissue may also be of importance in this sense. In fact, not all biohumoral parameters investigated were similar to those of diabetes because the behaviour of somatotropinaemia, free glycerol and plasma triglycerides was normal. The changed behaviour of phosphorus would thus indicate altered glucose uptake at peripheral tissue level.
