A drug used to treat the symptoms of skin psoriasis may also help to reduce symptoms of nail psoriasis, a new study has suggested.
According to a report in the March issue of Archives of Dermatology, low-dose acitretin may help to treat irregular pitting, salmon-coloured patches on the nails and onycholysis, which involves the separation of the nail from the nail bed.
The study's authors, who were led by Antonella Tosti, of the University of Bologna, Italy, noted that, of all the participants whose conditions improved, the pre-treatment conditions did not return.
"Although more studies are required to thoroughly assess the effectiveness in larger controlled subject populations, our observations suggest that low-dose systemic acitretin should be considered in the therapeutic armamentarium in the treatment of nail psoriasis," the authors concluded.
Up to three-quarters of psoriasis patients (78 per cent) suffer from nail psoriasis, which is also defined by erythematous - reddened and inflamed borders on a number of fingernails or toenails.
People suffering from psoriasis have skin cells that reproduce in three to four days instead of the usual 28 to 30 days.
