Remisión de la psoriasis luego de bypass gástrico

psoriasis is a frequent skin disease affecting 1-3% of the population. recent studies have found that psoriasis is linked to higher rate of obesity, and that obesity itself is a risk factor for the development and severity of psoriasis. the common link between psoriasis and obesity may be a state of chronic inflammation, including elevated serum levels of cytokines such as tumor necrosis factor. consequently, weight loss has been proposed as a useful adjunctive therapy for obese patients with psoriasis. we present a 43-year old man with body mass index greater than 40kg/m2 who had marked improvement in his psoriasis after roux-en-y gastric bypass surgery. weight loss following bariatric surgery could play a role on the treatment for psoriasis on morbid obese patients.
