The Impact of Telemedicine for Monitoring and Treatment of Phenylketonuria Patients on Metabolic Outcome During Coronavirus Disease-19 Outbreak

摘要

Introduction: The prognosis of phenylketonuria (PKU) in terms of neurocognitive outcome is directly related to lifelong phenylalanine (Phe) levels and adherence to treatment. Monitoring and treatment of PKU patients can be complicated in challenging circumstances as pandemics. This study aims to evaluate the impact of telemedicine for monitoring and treatment of PKU patients on metabolic outcome during coronavirus disease-19 (COVID-19) outbreak.Materials and Methods: Patients who were diagnosed as PKU and treated with low Phe diet, tetrahydrobiopterin (BH4), or BH4 adjunct with low Phe diet were enrolled. Study period was divided into two periods: prepandemic period wherein patients were followed up in outpatients' clinic and during pandemic wherein telemedicine was used. Demographic findings, laboratory results, and therapy responses were reviewed retrospectively and compared between the two periods. All procedures were in accordance with the ethical standards of the local ethical committee of Cerrahpasa Medical Faculty (17/11/2020-151640) and with the Helsinki Declaration of 1975, as revised in 2013.Results: Ninety-three (n = 93) patients were enrolled to this study. The ratio of the samples with Phe levels in the recommended ranges was found to be statistically higher during the pandemic wherein an online monitoring system was used in all treatment modalities (ppConclusions: Telemedicine can be an appropriate and effective monitoring option for PKU patients during the COVID-19 pandemic.
