[Maternal PKU syndrome as an obstetric problem: literature review and own clinical experience].
Maternal phenylketonuria (M-PKU) is a syndrome of embryo- and fetopathy observed in the offsprings of mothers with increased blood level of phenylalanine. These women fall into two groups: phenylketonuria (PKU) and mild hyperphenylalaninemia (MHP). The Phe--level safe for the fetus is 4-6 mg%. Typical for M-PKU syndrome is: microcephalia, mental retardation, intrauterine growth retardation, congenital heart diseases and other anomalies like esophageal atresia, meningocoele, Pierre-Robin syndrome, cataract. The only way to prevent this syndrome is Phe--restricted diet that should be initiated before conception. We reviewed updated literature on the pathogenesis of this syndrome, clinic, possibility of prophylaxis and treatment. We present also 5 pregnancies of 3 patients with PKU, treated in National Research Institute of Mother and Child in Warsaw. On that ground we propose the scheme of prevention of maternal PKU syndrome.
