Clinical and biochemical diagnostic studies concerned 17 cases of galactosemia coming from 15 not consauguineous families. Galactosemia was diagnosed between 1-st day and 11-th month of life. Tentative diagnosis based on clinical picture was made in 12 infants, others were detected through family history of galactosemia and/or biochemical newborn screening carried out at the National Research Institute of Mother and Child since 1969. Clinical symptoms of galactosemia occurred in most patients in the first week of life. They were the following (tab. II): hepatomegaly (in 94%), jaundice (81%), splenomegaly (79%), vomitus (62%) and diarrhoea in 56% of patients. Cataract was found in 6 infants (38%). Biochemical diagnosis was based on the results of enzymatic estimation of galactose-1-phosphate uridyl transferase activity in blood, galactose-1-phosphate in red blood cells and galactose in blood and urine. No activity of galactose-1-phosphate uridyl transferase was found in all patients, and the concentration of galactose-1-phosphate was higher than 25 mg/100 ml of red blood cells. High galactose level was observed in blood and urine in all patients with typical clinical course of galactosemia. In 2 patients however without clinical symptoms of the disease only trace amounts of galactose was detected in blood and urine. All these patients were treated with galactose free diet.

It was recently shown in this laboratory that treatment of newborn animals with certain enzymic inducers causes stable changes in the activities of the inducible enzymes at a later adult stage. Cataracts, hepato-splenomegaly and other galactosemia symptoms in galactosemic W/SSM rats develop spontaneously. The increased uptake of galactose by erythrocytes, but not the decreased level of galactose-1-phosphate uridyl transferase (Gal-1-PUT) activity was assumed to be the major cause of the disease. The administration of galactose to the newborn W/SSM rats (2 mg/g of body weight for 14 days) resulted in a sustained decline in the uptake of 14C-galactose by erythrocytes at least for five months, in an increase of glucoso-6-phosphate dehydrogenase activity and in a continuous fall of Gal-1-PUT activity. The neonatal treatment of the galactosemic rats with galactose abolished the main symptoms of galactosemia (cararacts, hepato-splenomegally) in adult animals, perhaps ar a consequence of the stable changes in the galactose metabolism.
