Continuous use of glycomacropeptide in the nutritional management of patients w...
Pena, Maria João; Pinto, Alex; de Almeida, Manuela Ferreira; de Sousa Barbosa, Catarina; Ramos, Paula Cristina; Rocha, Sara; Guimas, ArlindoBackground: In phenylketonuria (PKU), modified casein glycomacropeptide supplements (CGMP-AA) are used as an alternative to the traditional phenylalanine (Phe)-free L-amino acid supplements (L-AA). However, studies focusing on the long-term nutritional status of CGMP-AA are lacking. This retrospective study evaluated the long-term impact of CGMP-AA over a mean of 29 months in 11 patients with a mean age at CGMP...
The Effect of Glycomacropeptide versus Amino Acids on Phenylalanine and Tyrosin...
Daly, Anne; Evans, Sharon; Chahal, Satnam; Santra, Saikat; Pinto, Alex; Gingell, Cerys; Rocha, Júlio César; van Spronsen, Francjan; Jackson, RichardIntroduction: In phenylketonuria (PKU), evidence suggests that casein glycomacropeptide supplemented with rate-limiting amino acids (CGMP-AA) is associated with better protein utilisation and less blood phenylalanine (Phe) variability. Aim: To study the impact of CGMP-AA on blood Phe variability using 3 different dietary regimens in children with PKU. Methods: This was a 6-week randomised controlled cross-over ...
Long-Term Growth in Phenylketonuria: A Systematic Review and Meta-Analysis
Ilgaz, Fatma; Pinto, Alex; Gökmen-Özel, Hülya; Rocha, Júlio César; van Dam, Esther; Ahring, Kirsten; Bélanger-Quintana, Amaya; Dokoupil, KatharinaThere is an ongoing debate regarding the impact of phenylketonuria (PKU) and its treatment on growth. To date, evidence from studies is inconsistent, and data on the whole developmental period is limited. The primary aim of this systematic review was to investigate the effects of a phenylalanine (Phe)-restricted diet on long-term growth in patients with PKU. Four electronic databases were searched for articles ...
Over Restriction of Dietary Protein Allowance: The Importance of Ongoing Reasse...
Pinto, Alex; Almeida, Manuela Ferreira; MacDonald, Anita; Ramos, Paula Cristina; Rocha, Sara; Guimas, Arlindo; Ribeiro, Rosa; Martins, EsmeraldaPhenylalanine (Phe) tolerance is highly variable in phenylketonuria (PKU) and rarely described in patients aged ≥12 years. Patients ≥12 years of age with PKU were systematically challenged with additional natural protein (NP) if blood Phe levels remained below 480 µmol/L (i.e., upper target blood Phe level for patients aged ≥12 years using Portuguese PKU guidelines). In PKU patients, NP tolerance was calculated...
Dietary practices in methylmalonic acidaemia: a European survey
Pinto, Alex; Evans, Sharon; Daly, Anne; Almeida, Manuela Ferreira; Assoun, Murielle; Bélanger-Quintana, Amaya; Bernabei, Silvia MariaBackground -The dietary management of methylmalonic acidaemia (MMA) is a low-protein diet providing sufficient energy to avoid catabolism and to limit production of methylmalonic acid. The goal is to achieve normal growth, good nutritional status and the maintenance of metabolic stability. Aim -To describe the dietary management of patients with MMA across Europe. Methods - A cross-sectional questionnaire was s...
