Biological effects of a dietary omega-3 polyunsaturated fatty acids supplementation in cystic fibrosis patients: a randomized, crossover placebo-controlled trial.

Background And Aims: Various anti-inflammatory therapies, including dietary omega-3 polyunsaturated fatty acids (PUFA) supplementation, have been investigated in cystic fibrosis (CF) patients. To further explore this nutritional approach, biological effects of an omega-3 PUFA oral liquid supplementation were measured in 17 CF patients in a double-blind, randomized, crossover without a washout period and placebo-controlled study.

Methods: CF patients (age: 18+/-9 year; weight: 43+/-13 kg) received a liquid dietary supplementation either enriched or not in omega-3 PUFA (390-1170 mg/day according to patient weight) during two 6-month periods.

Polyunsaturated fatty acid deficiency reverses effects of alcohol on mitochondrial energy metabolism.

Background/aims: Polyunsaturated fatty acids (PUFA) deficiency is common in patients with alcoholic liver disease. The suitability of reversing such deficiency remains controversial. The aim was to investigate the role played by PUFA deficiency in the occurrence of alcohol-related mitochondrial dysfunction.
