RESUMO
According to the WHO, sexual health is not merely the absence of disease. Sexual dysfunction may be present in 40.8% of psoriasis patients, furthermore, 68% prevalence was found in Brazilian women with psoriasis. The moderate prevalence of psoriatic lesions in the genital area (35%-42%) does not explain the alarming prevalence of sexual dysfunction. Other factors, such as anxiety, depression, and also psoriasis treatment may contribute to its development. Likewise, atherosclerosis of the pelvic vasculature is involved in the pathogenesis of erectile dysfunction. Risk factors for erectile dysfunction tend to be confused with the comorbidities seen in psoriasis patients. We also highlight that it may serve as a marker of cardiovascular risk.
RESUMO
The treatment effect against psoriasis of an antigen (delipidated, deglycolipidated form of M. vaccae-PVAC) was investigated. One hundred and sixty-five patients were enrolled in three arms (50 or 15 microg or placebo), each receiving a total of two intradermal injections (days 0 and 21). At week 12, a 75% decrease in psoriasis area and severity index was similar among the studied groups (13, 9 and 18%, p=0.429). The overall incidence of adverse events was significantly higher in the PVAC treated groups when compared to placebo (98.2, 87.3 and 70.9%; p<0.001) largely due to local reactions that were limited for the most part to grades 1 and 2 in severity and were self-limiting. Despite its overall safety, PVAC was not clearly indicated to be superior to placebo in the treatment of psoriasis in this study.
