Topical treatment of recurrent vulvovaginal candidiasis: an expert consensus

Article

A study published in Women’s Health Reports suggests best practices for treating recurrent vulvovaginal candidiasis.

A new consensus, published in Women’s Health Reports, offers a clear roadmap to mycologic (fungal) cure for the 1 in 10 women who suffer recurrent vulvovaginal candidiasis (RVVC)1 3 or more times yearly.

A panel of 5 ob-gyns2 specializing in RVVC met to develop guidelines for the condition’s effective and safe maintenance, given the lack of one offered by the US Centers for Disease Control and Prevention.

“The CDC does not provide recommendations for the type or frequency of topical maintenance, leaving clinicians without templates regarding best practice,” says lead author Nancy A. Phillips, MD,3 of Topical Treatment of Recurrent Vulvovaginal Candidiasis: An Expert Consensus.4

The group concluded that women with RVVC should be treated longer than those with non-recurrent VVC, starting with initial treatment of 7 to 14 days of topical therapy—versus 1-7 days—or 3 doses of fluconazole, with 100-, 150- or 200-mg. taken by mouth once every 3 days.

The type of yeast should be confirmed before treatment. Oral flucoconazole is ineffective against nonalbicans yeast, the cause of 1 in 5 fungal infections.

The doctors suggest 6 months of maintenance doses 1 to 3 times weekly—usually twice weekly—of topical azoles (clotrimazole, miconazole and terconazole) against C. albicans fungi and nonterconazole azole for nonalbicans fungi, unless terconazole worked for the patient previously.

Contributing factors to recurrent infections also should be addressed, such as intrauterine devices and diabetes. Ideally, diabetic patients should control blood sugar with drugs other than sodium glucose cotransporter two inhibitors (SGLT2).5 Corticosteroids and antibiotics should be minimized.

The panel also raised risks of some drugs.

Oral fluconazole can endanger women who are on statin drugs, have kidney disease or are at risk for arrhythmias.

It also can cause miscarriages. Indeed, a 2015 nationwide cohort study in Denmark showed a significantly higher chance of miscarriage and stillbirths in women taking oral fluconazole versus those who did not or who used a topical azole.6

Intravaginal boric acid and ibrexafungerp, an oral drug the US Food and Drug Administration approved last June,7 also can cause miscarriages.

Only 7-day azoles should be used during pregnancy or in women planning to become pregnant.

The 30-50% of women who continue to have recurrent infections after six months of maintenance treatment should see a RVVC specialist, the panel concludes.
