A double-blind placebo controlled trial of efamol marine on skin and joint symptoms of psoriatic arthritis

Fish oil may be beneficial in the treatment of psoriasis and in RA. We examined the potential benefit of Efamol Marine, a combination of evening primrose oil and fish oil in the treatment of 38 patients with PsA. Patients with PsA were entered in a double-blind placebo controlled study and received either 12 Efamol Marine capsules or 12 placebo capsules daily for 9 months. All patients received placebo capsules for a further 3 months. At month 3 of the study patients were asked to reduce their intake of NSAIDs and maintain that decrease provided there was no worsening of their joint symptoms. Clinical assessments of skin and joint disease severity and activity were performed at 0, 1, 3, 6, 9 and 12 months
