Coping with inverse psoriasis

Q: What would you suggest to patients who are dealing with itch from inverse psoriasis?

A: Itch is a big problem. Pain is a big problem, too, because the skin in these areas is torn or eroded or ulcerated, and many times, very painful to touch. So in addition to a gentle cleanser, maybe add a mild topical steroid with Eucerin moisturizer or plain Aquaphor. Sarna lotion is a very good anti-itch and cooling over-the-counter product along with a mild cortisone.

Q: Do you find that antihistamines are effective for itch related to inverse psoriasis?

A: I think it is effective in the same way it would be effective for other issues of the skin. I like to use both H1 and H2 antihistamines. I’ll use something like hydroxyzine at night, especially when a better night’s sleep is needed. In most cases, it won’t give you a hangover the next morning. Then, use a non-sedating antihistamine like Fexofenadine during the day.  

Q: Is it normal for inverse psoriasis to be weepy or moist? Is it okay to use products like baby powder or cornstarch to keep these areas dry?

A: Infection and weeping of skinfolds is a frequent and frustrating problem. I think baby powder and cornstarch are fine as long as the lesion is not too wet to where you get a lot of caking and buildup of debris. Putting a Kleenex or a washcloth in with it to help soak up any of the excessive moisture might help.

Q: Are there materials for undergarments that are better necessarily than others?

A: Well, I think cotton is the best way to go, and I think anything with fragrance or dyes that can act as an irritant might be a problem. This includes detergents, so watch for contact dermatitis or primary irritation. With laundering, double rinsing may be necessary to minimize irritation.

Q: Other than washing several times a day, what can you do about the smell or the odor?

A: Typically, body odors are generated by bacterial flora of different types. So the key approach I think is frequent bathing with gentle bathing methods that don’t irritate the affected areas and possibly some sort of an antibacterial topical agent. Neo-Synalar might be a good one to start with and, maybe, if the body odor continues, cultures of skin folds for possible unusual microbial flora would be in order.
