Abstract

Background

Phenylketonuria (PKU) is a metabolic disorder resulting in high phenylalanine (Phe) blood concentrations due to the deficiency of the hepatic enzyme Phe hydroxylase. High Phe levels are currently treated with diet, thus avoiding mental retardation, psychomotor delay, etc. The aim of this study was to find out the self-presentation of the disease by the patients.

Methods

A total number of 110 patients self-represented their disease: food allergy (Phe allergy) n = 34/110 (30.9%), health problems n = 31/110 (28.2%), severe health problems n = 26/110 (23.6%), very severe health problems n = 19/110 (17.3%). The Wechsler Intelligence Scale for Children (WISC III) psychometric test was utilized for the evaluation of IQ scores of each participant. A special questionnaire was used focusing on quality of life (QL), social discrimination (SD) and anxiety or depression (AD).

Results

IQ scores were found to be higher in food allergy self-represented patients than those of the other tested groups. The lowest IQ scores were observed in those who represented very severe disease. QL, SD and AD were not observed in the food allergy groups. On the contrary, those who self-presented as very severe diseased patients felt high a disturbance of QL, SD and AD.

Conclusions

The food allergy group seemed to be a very clever excuse for adhering to PKU treatment resulting in high IQ scores and absence of the mentioned upsets. In contrast, in the other groups of patients’ IQ scores were found to be lower than that of food allergy group. Damage of QL, SD, AD were also apparent.
