Overview

Newborn screening for phenylketonuria (PKU) is key to early diagnosis but is not available globally. Discrepancies in newborn screening programs and their challenges in Brazil, Eastern Europe and Turkey will be explored. Successful case finding by newborn screening allows treatment to start early, and patients to develop with intelligence within normal limits, though often with some suboptimal neurocognitive function (van Spronsen, 2021). Treatment options, including dietary restriction of phenylalanine, tetrahydrobiopterin and pegylated phenylalanine ammonia lyase will be discussed. Advances in genetic research has shed light on how variants in the PAH gene impact the severity of an individual’s PKU [Hillert, 2020], and has emphasized the importance of personalized treatment. Research is also shedding light on the mechanisms of PKU neurotoxicity and how to prevent them. The lifelong effect of PKU on patients will be discussed, particularly a tendency in patients towards obesity and consequently hypertension, and how the condition effects diet, exercise and well-being. The webinar, which forms the core of this learning journey, will focus on current and future treatments for PKU, and also address some of the underlying metabolic and neurological problems associated with phenylalanine dysfunction.

Learning Objectives

After attending this educational programme, participants will be able to:

  • 1. Outline best practice for newborn screening for PKU
  • 2. Recognize the impact of exercise on health of patients with PKU
  • 3. Identify the key issues impacting adolescents with PKU
  • 4. Explain the impact of guidelines on patient outcome
  • 5. Understand how variants in the PAH gene impact the severity of an individual’s PKU
  • 6. Describe mechanisms of neurotoxicity in PKU
  • 7. Relate the need for personalized nutritional care with the use of adjunct drug treatment in PKU

Target Audience

Specialists in paediatric and adult inherited metabolic disorders, dietitians, nutritionists, clinical biochemists and geneticists, basic scientists, psychologists, gynaecologists and obstetricians, nurses and all healthcare professionals helping those with PKU.

Language

The official language of this educational programme will be English.

Continuing Medical Education

The PKU BLENDED LEARNING JOURNEY 2025 will be submitted for CME accreditation from the European Accreditation Council for Continuing Medical Education (EACCME) and/or the European Board for Accreditation of Continuing Education for Health Professionals (EBAC) and for Continuing Professional Development (CPD) credits.

He was head of the Paediatric Endocrine Unit at Barts and the London School of Medicine from 1982 to 2007. He has interests in growth disorders, specifically those with abnormalities in the GH-IGF-1 axis and in phenotype-genotype relationships of GH-IGF-1 axis defects, notably GH resistance. He published the first human case of an IGF-1 gene defect in the New England Journal of Medicine in 1996.  His other interests are Cushing’s syndrome and growth in chronic inflammatory diseases. He was General Secretary of the European Society for Paediatric Endocrinology (ESPE) from 1997 to 2004. He has lectured in 60 countries and has published 482 original articles, reviews, textbook chapters and books. In 2007, he was awarded the ESPE Andrea Prader Prize for contributions to paediatric endocrinology and in 2018 he received a Visionary Award from the American Human Growth Foundation.

He was the Head of the Laboratory for Tetrahydrobiopterin and Neurotransmitter Diseases at the University Children’s Hospital in Zürich, Switzerland, where his research group discovered several inborn errors of metabolism, including GTPCH, PCD and SR deficiencies. He established and curates the phenylalanine hydroxylase (PAH) locus-specific database, BIOPKU database of phenylketonuria (PKU) genotypes, database of tetrahydrobiopterin (BH4) deficiencies and the PNDdb database of mutations causing pediatric neurotransmitter disorders (www.biopku.org). With colleagues from Vancouver (BC, Canada), he developed the IEMbase, an online knowledgebase and diagnostic tool for inborn errors of metabolism (www.iembase.org). His current research focuses on epidemiology, population genetics, genotype-phenotype correlation, and genotypic phenotype prediction in PKU and other inherited metabolic diseases.

Prof. Blau is an honorary member of the Italian Society for Pediatrics. In 2001, he received the Horst­ Bickel-Award, in 2005 the Gowland Hopkins Award and in 2011 the Asbjørn Følling Award for his research in the field of tetrahydrobiopterin and PKU.

She was trained in Denmark, Italy, Great Britain, Qatar, USA and Japan.  Phenylketonuria and other inborn errors of metabolism were the subjects of her lectures given in many European countries, USA and Canada, South America, China, Japan, Australia and in the Middle East. On many occasions she was the presenter at the Metabolic University at Colorado Children’s Hospital in Denver where her lectures focused on phenylalanine neurotoxicity and untreated adults with phenylketonuria as well as inborn errors of metabolism with intoxication syndrome. From 2011 to 2021 professor Giżewska with her German partners (Universities in Greifswald and Medical University Charitè in Berlin) carried out two European Union transborder projects (Program Interreg IVA and VA) dedicated to the creation of Polish-German newborn screening programs aimed to early detection of newborns with rare genetic conditions, including inborn errors of metabolism, endocrinological disorders, cystic fibrosis and recently, severe combined immunodeficiencies (SCID). At the moment, she is a promotor of the National Center of Science grant:  Does a life-long low-phenylalanine diet have an impact on renal function in patients with phenylketonuria? Professor Giżewska is a member of SSIEM, ISNS, Polish Pediatric Societies, Polish Society of Pediatric Endocrinology and Polish Society of Inborn Errors of Metabolism. She is also a vice-chair of Polish Society of Phenylketonuria and a vice-chair of ESPKU Scientific Advisory Committee.
