What’s New in Psoriasis


Psoriasis is characterized by red scaly plaques, especially on the elbows and knees. However, it can affect anywhere on the body, including the private areas. This is part of the reason psoriasis patients suffer from a “very large negative effect” on their lives. This was seen in a 2011 study of the injectable medication Stelara when patients answered a standardized questionnaire (Dermatology Life Quality Index). The study was important in finding a 22.6% rate of impaired sexual function, seen more in females than males. Importantly, this rate decreased to 2.7% after 3 months of treatment. A more recent study of the yet-to-be-approved systemic medication ixekizumab (an easier to say brand name will be used once the medication is approved) found an even higher 32% rate of self-reported psoriasis-related sexual difficulties, decreasing to 7% after 4 months of treatment.

Overall, the takeaway message isn’t that a specific medication would be useful in assisting psoriasis patients who suffer from sexual dysfunction. However, it does seem that the better the psoriasis is controlled, whether by topicals (ie, creams/ointments), phototherapy (using the medical phototherapy booth we have in our office), or systemics (pills or injections), the better the quality of life for patients, including the private areas of their lives.

If you have psoriasis, of whatever severity, I look forward to seeing you. Please make an appointment for a dermatology consultation at (626) 331-6411.
