Principles of Treatment for Inborn Errors of Metabolism

This topic builds upon the diagnosis of inherited metabolic disorders (IMDs) by focusing on their management, a crucial area for advanced clinical biochemistry students in Zambia. It covers the therapeutic strategies used to mitigate the effects of enzyme defects, including dietary restriction of substrate precursors (e.g., low-phenylalanine diet for PKU), supplementation of deficient products (e.g., cortisol in congenital adrenal hyperplasia), removal of toxic metabolites (e.g., ammonia in urea cycle disorders), and the use of cofactors or enzyme enhancers. For Zambian university learners, understanding these principles is essential for comprehensive patient care and is often examined in final year assessments. This knowledge prepares graduates for roles in metabolic clinics, paediatric nutrition, and genetic counselling, contributing to improved outcomes for affected individuals in Zambia.
