[Financial justification of investments into special diet for patients with phenylketonuria].

INTRODUCTION Phenylketonuria is a genetic disorder of metabolism of amino acid phenylalanine, which results in the absence of phenylalanine hydroxylase, an enzyme that catalyzes the conversion of phenylalanine into tyrosine. It is an autosomal recessive disorder. Screening for phenylketonuria in Voivodina started in 2003. Screening data are shown in this paper. Treatment of phenylketonuria is based on a strict, life long, low protein diet with the controlled phenylalanine intake. Diet must start early, in the first weeks of life. The aim of the diet is to reduce natural protein intake and to cover protein needs by special phenylalanine free protein products. There is a big variety of formulas found available on the market for treatment of phenylketonuria. All of them are free of phenylalanine and very expensive. DISCUSSION Till May 2005 there was no refunding for these products in our country. According to the decision made by the Provincial Secretariat for Health, providing all children with protein supplement in their first year of life started at the Institute for Child and Youth Healthcare. In September 2007 the Republic Fund for Health Insurance started to refund protein supplement and low protein products for all children up to the age of 18 years. CONCLUSION Besides all technical and organizational difficulties associated with this work, this paper also shows how, by good prevention of phenylketonuria complications, much more money can be saved than it has been invested, even in countries with low amounts of money allocated for this purpose (in absolute figures).
