Depression is common and under-diagnosed in AFD. Proper assessment of and treatment for depression could improve the quality of life of these patients.
The approach to adult patients with OA has to be multidisciplinary, with the clinician and dietician as the core of the team, but with the collaboration of clinical nurses specialists, social workers and other specialist services and the support of a biochemical and molecular laboratory.
The findings suggest that the majority of patients with PKU were under-treated. The NHS cost of patient management should not be an obstacle to encouraging patients to remain on a restricted diet until further information becomes available about the long-term clinical impact of stopping such a diet. Nevertheless, patients require counselling and managed follow up regardless of the choices they make about their diet.
More women with phenylketonuria are becoming pregnant and need appropriate management to avoid the effects of raised phenylalanine on the fetus: facial dysmorphism, microcephaly, growth retardation, developmental delay and congenital heart disease. Here we describe our experiences from a single centre gained over almost three decades. A series of six cases is presented to illustrate key points in management. Ideally, phenylalanine-restricted diet is started before conception in a planned fashion, but some women present pregnant and blood phenylalanine must be lowered rapidly. The aims of management are to maintain blood phenylalanine concentration in the target range (100-250 micromol/L) before and throughout the pregnancy, and to ensure adequate maternal nutrition and appropriate weight gain. Blood phenylalanine is monitored twice, three times a week, before and after conception respectively. Weight is monitored on a weekly basis and key micronutrients are monitored every 6-8 weeks in clinic. From the second trimester onwards, dietary phenylalanine intake has to be promptly increased, as phenylalanine tolerance increases rapidly. Postnatal management includes a neurological assessment of the infant at 4-8 weeks and an echocardiogram for infants conceived off diet. Subsequently, offspring are seen at 1 year, 4 years, 8 years and 14 years for neuropsychometric evaluations. Regular follow-up of the mother remains important whether on or off a phenylalanine-restricted diet.
Fabry disease patients have increased risk of vascular disease despite cardioprotective increased HDL-cholesterol. Enzyme therapy does not significantly alter the lipid profile in the short term.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
