Abstract

Docosahexaenoic acid (DHA) deficiency has recently been documented in several children with long-chain L-3-hydroxyacyl-coenzyme A dehydrogenase deficiency (LCHADD). We studied a 13-year-old boy with LCHADD who had limb girdle myopathy, recurrent myoglobinuria, and progressive sensorimotor axonopathy with demyelination. At 11 years of age, he was started on cod liver oil extract, high in DHA content. Over 12 months, he demonstrated a marked clinical recovery. Nerve conduction studies (NCS) demonstrated reappearance of previously absent posterior tibial and peroneal nerve responses and the amplitudes on motor ulnar and median NCS markedly increased from 7- to 14-fold, respectively.
