Treatment Adherence and Psychological Wellbeing in Maternal Carers of Children with Phenylketonuria (PKU).

ABSTRACT: Phenylketonuria (PKU), a rare metabolic disorder, causes cognitive impairment unless treated with a strict, protein-restricted diet, but few studies have examined the relationship between treatment compliance and parental wellbeing. In the present study, 46 primary caregivers of children with PKU completed measures of psychological distress, parenting stress (related to caring for a child with an illness), resilience, perceived social support and child dependency. Treatment adherence was assessed using the proportion of blood phenylalanine concentrations within target range in the preceding year. Results indicated that 59% of caregivers showed clinical levels of psychological distress, which was predicted by their parenting stress and resilience. Whilst the proportion of blood phenylalanine concentrations in range was not associated with parental distress, it was predicted by child age and caregiver's perceived support from family. Despite experiencing high levels of distress, the results indicated that caregivers' ability to adhere to treatment was not affected. Interventions to reduce parenting stress and boost caregiver resilience may have a positive effect on parental wellbeing. Additionally, interventions to promote treatment adherence benefit parents of older children, with a focus on promoting support from family members. Further research with larger sample sizes and longitudinal designs is needed to further establish causal mechanisms.

Project description:BackgroundInsufficient metabolic control during pregnancy of mothers with phenylketonuria (PKU) leads to maternal PKU syndrome, a severe embryo-/fetopathy. Since maintaining or reintroducing the strict phenylalanine (Phe) limited diet in adults with PKU is challenging, we evaluated the most important dietary and psychosocial factors to gain and sustain good metabolic control in phenylketonuric women throughout pregnancy by a questionnaire survey with 38 questions concerning therapy feasibility. Among them, the key questions covered 5 essential items of PKU care as follows: General information about maternal PKU, PKU training, diet implementation, individual metabolic care, personal support. In addition, all participating PKU mothers were asked to estimate the quality of their personal metabolic control of the concluded pregnancies. 54 PKU mothers with 81 pregnancies were approached at 12 metabolic centers in Germany and Austria were included. According to metabolic control, pregnancies of PKU women were divided in two groups: group "ideal" (not more than 5% of all blood Phe concentrations during pregnancy > 360 µmol/l; n = 23) and group "suboptimal" (all others; n = 51).ResultsThe demand for support was equally distributed among groups, concerning both amount and content. Personal support by the direct social environment (partner, family and friends) ("suboptimal" 71% vs "ideal" 78%) as well as individual metabolic care by the specialized metabolic center (both groups around 60%) were rated as most important factors. The groups differed significantly with respect to the estimation of the quality of their metabolic situation (p < 0.001). Group "ideal" presented a 100% realistic self-assessment. In contrast, group "suboptimal" overestimated their metabolic control in 53% of the pregnancies. Offspring of group "suboptimal" showed clinical signs of maternal PKU-syndrome in 27%.ConclusionThe development of training programs by specialized metabolic centers for females with PKU in child bearing age is crucial, especially since those mothers at risk of giving birth to a child with maternal PKU syndrome are not aware of their suboptimal metabolic control. Such programs should provide specific awareness training for the own metabolic situation and should include partners and families.

Project description:BACKGROUND: Phenylketonuria (PKU) is an autosomal recessive disorder of phenylalanine metabolism. The inability to convert phenylalanine (Phe) into tyrosine causes Phe to accumulate in the body. Adherence to a protein restricted diet, resulting in reduced Phe levels, is essential to prevent cognitive decline. Frequent evaluation of plasma Phe levels and, if necessary, adjustment of the diet are the mainstay of treatment. We aimed to assess whether increased self-management of PKU patients and/or their parents is feasible and safe, by providing direct online access to blood Phe values without immediate professional guidance. METHODS: Thirty-eight patients aged ≥ 1 year participated in a 10 month randomized controlled trial. Patients were randomized into a study group (1) or a control group (2). Group 2 continued the usual procedure: a phone call or e-mail by a dietician in case of a deviant Phe value. Group 1 was given a personal "My PKU" web page with a graph of their recent and previous Phe values, online general information about the dietary treatment and the Dutch PKU follow-up guidelines, and a message-box to contact their dietician if necessary. Phe values were provided on "My PKU" without advice. Outcome measures were: differences in mean Phe value, percentage of values above the recommended range and Phe sample frequency, between a 10-month pre-study period and the study period in each group, and between the groups in both periods. Furthermore we assessed satisfaction of patients and/or parents with the 'My PKU' procedure of online availability. RESULTS: There were no significant differences in mean Phe value, percentage of values above recommended range or in frequency of blood spot sampling for Phe determination between the pre-study period and the study period in each group, nor between the 2 groups during the periods. All patients and/or parents expressed a high level of satisfaction with the new way of disease management. CONCLUSIONS: Increased self-management in PKU by providing patients and/or parents their Phe values without advice is feasible and safe and is highly appreciated. TRIAL REGISTRATION: The trial was registered with The Netherlands National Trial Register (NTR #1171) before recruitment of patients.
