BACKGROUND: Information on peripheral neuropathy in children with cystic fibrosis is scanty. The etiology can be multifactorial (micronutrient deficiency, chronic hypoxia, impaired glucose tolerance, immunological, vasculopathic, critical illness). METHODS: Forty five cystic fibrosis children aged 1-18 years on vitamin E supplementation for at least 6 months underwent detailed neurological examination, serum vitamin E, vitamin B12, folate, copper levels and detailed nerve conduction studies. RESULTS: The mean age of the study population was 8.35 years (±4.9 years) with 62.2% being males. Overall 22 out of 45 (48.88%,CI: 33.7-64.2) had electrophysiological evidence of peripheral neuropathy which was predominantly axonal (86.4%), sensory (50%), and polyneuropathy (95.45%). There was no significant association between status of serum micronutrients and electrophysiological evidence of peripheral neuropathy. CONCLUSION: Patients with cystic fibrosis have electrophysiological evidence of peripheral neuropathy (predominantly axonal, sensory and polyneuropathy). There is significant association of higher chronological age with occurrence of peripheral neuropathy.
