Abstract:
OBJECTIVES:To study the efficacy of a low-copper diet guidance based on food exchange portions in children with hepatolenticular degeneration.
METHODS:A self-controlled study was conducted from July 2021 to June 2022, including 30 children under the age of 18 who were diagnosed with hepatolenticular degeneration and poorly controlled with a low-copper diet. During the medical visit, personalized low-copper diet guidance was provided to the children and their parents using a copper-containing food exchange table and a copper food exchange chart. During home care, compliance with the low-copper diet of the children was improved by recording dietary diaries and conducting regular follow-ups. The changes in 24-hour urine copper level, liver function indicators, and the low-copper diet knowledge of the children's parents were observed before and after the intervention, with no change in the original drug treatment.
RESULTS:After 8, 16, and 24 weeks of intervention, the 24-hour urine copper level decreased significantly compared to before intervention (P<0.05). When compared to 8-week intervention, the urine copper level decreased significantly after 16 and 24 weeks of intervention. The 24-hour urine copper level after 24 weeks of intervention decreased significantly compared to 16 weeks of intervention (P<0.05).After 24 weeks of intervention, the alanine aminotransferase and aspartate aminotransferase levels decreased significantly compared to before intervention (P<0.05). Additionally, in 16 of the cases (53%), alanine aminotransferase and aspartate aminotransferase returned to normal levels. Following 8 weeks of intervention, the low-copper diet knowledge of the children's parents increased significantly (P<0.05).
CONCLUSIONS:A low-copper diet guidance based on food exchange portions can effectively decrease the urine copper level and improve liver function in children with hepatolenticular degeneration. Furthermore, it can increase the low-copper diet knowledge of the children's parents.
