“Ibrexafungerp, an inhibitor of beta (1-3)–glucan synthase, is important for many reasons,” Dr. Venkatesan, chief of dermatology and director of the genital dermatology clinic at Santa Clara Valley Medical Center, San Jose, Calif., said during the annual meeting of the Pacific Dermatologic Association. “It’s one of the few drugs that can be used to treat Candida glabrata when C. glabrata is resistant to azoles and echinocandins. As the second-most common Candida species after C. albicans, C. glabrata is more common in immunosuppressed patients and it can cause mucosal and invasive disease, so ibrexafungerp is a welcome addition to our treatment armamentarium,” said Dr. Venkatesan, clinical professor of dermatology (affiliated) at Stanford (Calif.) Hospital and Clinics, adding that that vulvovaginal candidiasis can be tricky to diagnose. “In medical school, we learned that yeast infection in a woman presents as white, curd-like discharge, but that’s actually a minority of patients.”
For a patient who is being treated with topical steroids or estrogen for a genital condition, but is experiencing worsening itch, redness, or thick white discharge, she recommends performing a KOH exam.
“Instead of using a 15-blade scalpel, as we are used to performing on the skin for tinea, take a sterile [cotton swab], and swab the affected area. You can then apply it to a slide and perform a KOH exam as you normally would. Then look for yeast elements under the microscope. I also find it helpful to send for fungal culture to get speciation, especially in someone who’s not responding to therapy. This is because non-albicans yeast can be more resistant to azoles and require a different treatment plan.”
Often, patients with vulvovaginal candidiasis who present to her clinic are referred from an ob.gyn. and other general practitioners because they have failed a topical or oral azole. “I tend to avoid the topicals,” said Dr. Venkatesan, who is also president-elect of the North American chapter of the International Society for the Study of Vulvovaginal Disease. “If the culture shows C. albicans, I usually treat with oral fluconazole, 150 mg or 200 mg once, and consider repeat weekly dosing. Many patients come to me because they have recurrent refractory disease, so giving it once weekly for 6-8 weeks while they work on their potential risk factors such as diabetic blood sugar control is sensible.”
Non-albicans yeast can be resistant to azoles. If the fungal culture shows C. glabrata in such patients, “consider a course of intravaginal boric acid suppositories,” she advised. “These used to be difficult to give patients, because you would either have to send the prescription to a compounding pharmacy, or have the patients buy the capsules and boric acid crystals separately and make them themselves. That always made me nervous because of the chance of errors. The safety and the concern of taking it by mouth is an issue.” But now, intravaginal boric acid suppositories are available on Amazon and other web sites, and are relatively affordable, she said, adding, “just make sure the patient doesn’t take it by mouth as this is very toxic.”
Dr. Venkatesan reported having no financial disclosures.
