Protein intake and prevalence of overweight in patients with phenylketonuria: A...
Rodrigues, C; Barbosa, CS; de Almeida, MF; Bandeira, A; Martins, E; Rocha, S; Guimas, A; Ribeiro, R; Soares, A; Moreira-Rosário, A; Dias, CCBackground: Overweight has been identified as a comorbidity associated with phenylketonuria (PKU). A systematic review with meta-analysis found that although patients with PKU had a similar body mass index (BMI) when compared to non-PKU controls, there was a significantly higher BMI when measured in patients described as having classical PKU. Objective: The aim of this retrospective longitudinal study was to id...
Phenylketonuria in Portugal: Genotype–Phenotype Correlations Using Molecular, B...
Ferreira, F; Azevedo, L; Neiva, R; Sousa, C; Fonseca, H; Marcão, A; Rocha, H; Carmona, C; Ramos, S; Bandeira, A; Martins, E; Campos, T; Rodrigues, EBackground: The impairment of the hepatic enzyme phenylalanine hydroxylase (PAH) causes elevation of phenylalanine levels in blood and other body fluids resulting in the most common inborn error of amino acid metabolism (phenylketonuria). Persistently high levels of phenylalanine lead to irreversible damage to the nervous system. Therefore, early diagnosis of the affected individuals is important, as it can pre...

Congenital Disorders of Glycosylation in Portugal—Two Decades of Experience
Quelhas, D; Martins, E; Azevedo, L; Bandeira, A; Diogo, L; Garcia, P; Sequeira, S; Ferreira, AC; Teles, EL; Rodrigues, E; Fortuna, AM; Mendonça, CObjective: To describe the clinical, biochemical, and genetic features of both new and previously reported patients with congenital disorders of glycosylation (CDGs) diagnosed in Portugal over the last 20 years. Study design: The cohort includes patients with an unexplained multisystem or single organ involvement, with or without psychomotor disability. Serum sialotransferrin isoforms and, whenever necessary, a...
SLC35A2-CDG: Novel variant and review
Quelhas, D; Correia, J; Jaeken, J; Azevedo, L; Lopes-Marques, M; Bandeira, A; Keldermans, L; Matthijs, G; Sturiale, L; Martins, ESLC35A2 encodes the X-linked transporter that carries uridine diphosphate (UDP)-galactose from the cytosol to the lumen of the Golgi apparatus and the endoplasmic reticulum. Pathogenic variants have been associated to a congenital disorder of glycosylation (CDG) with epileptic encephalopathy as a predominant feature. Among the sixty five patients described so far, a strong gender bias is observed as only seven ...
Continuous use of glycomacropeptide in the nutritional management of patients w...
Pena, MJ; Pinto, A; de Almeida, MF; Barbosa, CD; Ramos, PC; Rocha, S; Guimas, A; Ribeiro, R; Martins, E; Bandeira, A; Dias, CC; MacDonald, ABackground 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-...
Interleukin-10 induces interferon-γ-dependent emergency myelopoiesis
Cardoso, A; Martins, AC; Maceiras, AR; Liu, W; Castro, I; Castro, AG; Bandeira, A; Di Santo, JP; Cumano, A; Li, Y; Vieira, P; Saraiva, MIn emergency myelopoiesis (EM), expansion of the myeloid progenitor compartment and increased myeloid cell production are observed and often mediated by the pro-inflammatory cytokine interferon gamma (IFN-γ). Interleukin-10 (IL-10) inhibits IFN-γ secretion, but paradoxically, its therapeutic administration to humans causes hematologic changes similar to those observed in EM. In this work, we use different in vi...

Pyruvate Dehydrogenase Complex Deficiency: Updating the Clinical, Metabolic and...
Pavlu-Pereira, H; Silva, MJ; Florindo, C; Sequeira, S; Ferreira, AC; Duarte, S; Rodrigues, AL; Janeiro, P; Oliveira, A; Gomes, D; Bandeira, ABackground: The pyruvate dehydrogenase complex (PDC) catalyzes the irreversible decarboxylation of pyruvate into acetyl-CoA. PDC deficiency can be caused by alterations in any of the genes encoding its several subunits. The resulting phenotype, though very heterogeneous, mainly affects the central nervous system. The aim of this study is to describe and discuss the clinical, biochemical and genotypic informatio...
Hematopoiesis: A Layered Organization Across Chordate Species
Elsaid, R; Soares-da-Silva, F; Peixoto, M; Amiri, D; Mackowski, N; Pereira, P; Bandeira, A; Cumano, AThe identification of distinct waves of progenitors during development, each corresponding to a specific time, space, and function, provided the basis for the concept of a “layered” organization in development. The concept of a layered hematopoiesis was established by classical embryology studies in birds and amphibians. Recent progress in generating reliable lineage tracing models together with transcriptional...
