Therapeutic modification of membrane lipid abnormalities in juvenile neuronal ceroid-lipofuscinosis (Batten disease)
Abstract
Five patients with juvenile neuronal ceroid-lipofuscinosis, who were shown to have absent or reduced serum prebetalipoprotein and a deficiency of polyunsaturated fatty acids in erythrocyte membrane lipids, were treated for a period of one year with supplements of fish oil extract (rich in omega-3 fatty acids) and encouraged to increase dietary intake of corn oil lipid (rich in omega-6 fatty acids) in an attempt to promote incorporation of these fatty acids into membranes. After one year there was a significant increase in omega-3 fatty acids (P less than 0.05) and in the total polyunsaturated fatty acids (P less than 0.02) in erythrocyte membranes but no change in the incorporation of omega-6 fatty acids. The patients were assessed clinically, psychometrically and neurophysiologically before and after the supplementation. No significant changes were noted after one year of treatment.
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
