The study has shown that the strengthening program applied to the families of children diagnosed with phenylketonuria (PKU) and the education given; It will be conducted in order to examine the effect of the family's coping attitudes, knowledge scores about the disease and its management. The research is of the randomized controlled experimental type. Children from PKU constitute the universe in the city center of Van. The families of children between the ages of 0-3 who were diagnosed with PKU will form the sample of the study. A nursing strengthening program will be applied to families in the experimental group for 10 weeks. The scope of this program; It consists of face-to-face training on disease management, giving the educational guide (booklet) for the families of babies diagnosed with PKU, telephone calls during the education process and counseling services. No application will be made to the families in the control group. After the application of the last tests to the control group; Face-to-face training and a booklet will be given to the experimental group. Data; It will be collected with 'Child and Family Introductory Information Form', 'Parents' Information Level Assessment Form about Phenylketonuria' and 'Coping Attitudes Assessment Scale'. In the literature, there is no study showing the effect of the education given to the families of babies diagnosed with PKU on their coping attitudes. Based on the need to fill this knowledge gap in the literature, it is thought that the study will contribute to the field of child health and disease nursing.
In the UK, some fruits and vegetables are permitted without measurement in the diets of people with phenylketonuria (PKU). It is proven that fruits and vegetables containing phenylalanine (Phe) up to 75mg/100g (e.g. carrots, sweet potato, tomatoes) do not affect blood Phe control but it is unknown to what extent fruits and vegetables containing Phe from 76-100mg/100g (e.g. cauliflower, broccoli, beansprouts and asparagus) increase blood Phe levels. In addition, there is very little information about how differently animal and vegetable protein affect blood Phe levels. It is believed that plant protein may have less bioavailability and therefore have less impact on blood Phe control. The investigators aim is to perform a randomized controlled study over 21 weeks in children (5-12y) with PKU. Children will be studied during five different time periods, examining the effect on blood Phe control when increasing Phe intake from vegetables/fruits containing Phe from 76-100 mg/100g vs. animal sources. At the end of the study, fruits and vegetables containing 76- 100mg Phe/100g will continue to be given as "exchange-free" for 6 months. This is a practical, cost effective study and should bring benefit to all people with PKU following a very restrictive diet both within the UK and throughout the world.
The main purpose of this trial is to evaluate the efficacy of PTC923 in reducing blood phenylalanine (Phe) levels in participants with phenylketonuria as measured by mean change in blood Phe levels from baseline to Weeks 5 and 6 (that is, the average of each respective treatment dose 2-week period of double-blind treatment).
PKU Sphere Liquid is a prospective, open-label, acceptability study to evaluate PKU sphere liquid in up to 15 participants aged 3 and above for the dietary management of PKU over 31 days.
PKU is a rare autosomal recessive condition associated with disruption in dopamine synthesis. Although early diagnosis and treatment prevent the severe impairments associated with untreated PKU, individuals with early-treated PKU (ETPKU) nonetheless experience significant sequelae, including impaired working memory and increased risk for anxiety problems. Past research with other clinical populations (e.g., generalized anxiety disorder) suggests that the two phenomena may be linked, with increased anxiety contributing to poorer WM performance. Currently we propose to initiate an exciting new line of research examining the potential relationship between anxiety and WM in ETPKU. The proposed study will also apply remote neuropsychological performance-based assessment to the study of ETPKU and thus overcoming the geographical limitations/challenges associated with recruitment of participants with this rare disease.
Patient suffering from phenylketonuria have chronic hyperphenylalaninemia. Hyperphenylalaninemia is known to be toxic to central nervous system and cardiovascular system in particular through oxydative stress. In this context, research of low grade systemic inflammation through cytokine assay appears legitimate. The primary outcome of this study is to describe inflammation profile of patients with phenylketonuria.
20 participants with PKU will build-up their dietary intake of PKU sphere over 2-16 weeks, depending on their level of metabolic control whilst doing so. Participants will complete a gastrointestinal specific and PKU specific questionnaire at the Baseline clinic visit and record the amount of PKU sphere taken each day. Dried blood spots are taken twice per week. Once built up to a clinically appropriate intake of PKU sphere, or after 16 weeks, participants enter a 4-week Evaluation Period. The amount of PKU sphere taken per day continues to be recorded by participants. Gastrointestinal tolerance over the preceding seven days is recorded at the end of each week. Evaluations of PKU sphere's palatability are made at the end of weeks two and four of the Evaluation Period. Dried blood spots are taken once per week. The participant attends an End of Study Visit at the clinic and the investigator decides whether they should continue taking PKU sphere.
This Phase 2 study in patients with phenylketonuria (PKU) will be an open-label, dual-arm study of either a SYNB1618 or SYNB1934 dose-ramp regimen. All evaluations and assessments throughout this study may be conducted either at the clinical site or by a home healthcare professional at an alternative location (e.g., patient's home, hotel).
This is a study for adults and children ≥ 14 years old who have Phenylketonuria (PKU) with uncontrolled plasma Phe levels. No clinical intervention or study drug is provided by BioMarin in this study.
