Don’t discount ultrapotent topical corticosteroids for vulvar lichen sclerosus

Ultrapotent topical corticosteroids remain the core treatment for vulvar lichen sclerosus, although other therapies can be added, according to an expert speaking at the virtual conference on diseases of the vulva and vagina.

Dr. Libby Edwards

If needed, intralesional steroid injections or calcineurin inhibitors can be added to a topical corticosteroid regimen, Libby Edwards, MD, suggested at the meeting, hosted by the International Society for the Study of Vulvovaginal Disease. In addition, early reports indicate that newer interventions such as fractional CO2 laser treatments may help patients with refractory disease.

Still, “there is no question, there is no argument: First-, second- and third-line treatment for lichen sclerosus is an ultrapotent or superpotent topical corticosteroid,” she said. Steroids include halobetasol, clobetasol, or betamethasone dipropionate in augmented vehicle ointment once or twice per day. Patients should continue this regimen until the skin texture is normal or the disease is controlled as well as possible, which usually takes several months, said Dr. Edwards, of Southeast Vulvar Clinic in Charlotte, N.C.

Patients then should continue treatment, but less frequently or with a lower potency steroid.

Although corticosteroids are not Food and Drug Administration–approved for the treatment of lichen sclerosus, double-blind, placebo-controlled trials support their use, Dr. Edwards said.

Getting patients to use topical corticosteroids as directed can be a challenge, however, and patient education is crucial.

After about 10 days, many patients start to feel better and stop the medication prematurely, which may lead to recurrence.

“That is such an important counseling point,” Aruna Venkatesan, MD, chief of dermatology and director of the genital dermatology clinic at Santa Clara Valley Medical Center in San Jose, Calif., said during a panel discussion. “Tell them, listen, I may not see you back for a couple months, and you may start feeling better sooner. But I want you to keep using this at this frequency so that when you come back we can make a good decision about whether you’re ready” for a lower potency regimen.

To encourage daily use, Hope K. Haefner, MD, asks patients whether they brush their teeth every night. “When they say yes, I tell them to put the steroid ointment by their toothpaste and use it after brushing,” Dr. Haefner, the Harold A. Furlong Professor of Women’s Health at Michigan Medicine in Ann Arbor, said during the discussion. “But don’t mix up the tubes.”

Once lichen sclerosus is controlled, options include decreasing the superpotent steroid to once, three times per week or changing to a midpotency steroid such as triamcinolone ointment every day, Dr. Edwards said.

Evidence suggests that controlling lichen sclerosus may prevent squamous cell carcinoma and scarring. In a study of more than 500 patients, about 70% complied with treatment instructions, whereas about 30% were considered partially compliant (JAMA Dermatol. 2015 Oct;151[10]:1061-7.). Patients who adhered to their therapy were less likely to have cancer or ongoing scarring during an average of 4.7 years of follow-up.
 

Beyond topical steroids

“Almost always, topical steroids are all you need,” said Dr. Edwards. “Before I go beyond that, I think of other issues that may be causing symptoms,” such as atrophic vagina, steroid dermatitis, or vulvodynia.

For patients with refractory lichen sclerosus, other treatments “can add more oomph to your topical steroid, but they are not better,” she said.

Intralesional corticosteroid injections are one option.

Another option is adding a calcineurin inhibitor such as tacrolimus or pimecrolimus, although these medications can burn with application and irritate. In addition, they carry warnings about rare cases of cancer associated with their use.

Dr. Edwards also uses methotrexate, which is supported by case reports and an open-label study. In a recently published study that included 21 patients with vulvar lichen sclerosus and 24 patients with extragenital lichen sclerosus, about half improved after receiving methotrexate (Dermatol Ther. 2020 Apr 29;e13473.).
 

What about lasers?

Fractional CO2 laser treatments, which are pulsed to minimize damage from heat, have “a lot of providers very excited,” Dr. Edwards said. In one open-label study of 40 patients, most reported a decrease in symptoms. (J Low Genit Tract Dis. 2020 Apr;24[2]:225-8.)

“We’re awaiting blinded, controlled studies,” Dr. Edwards said. “We don’t have those available yet although they are in progress.”

Ten of Dr. Edwards’ patients who did not improve enough with medication have received laser treatments. One patient stopped laser therapy after one treatment. One did not improve. Two were completely cleared, and six had significant improvement.

If patients who improved stopped steroids against recommendations, lichen sclerosus recurred, Dr. Edwards said.

The ISSVD does not recommend laser for the routine treatment of lichen sclerosus because of a lack of adequate studies and long-term safety data and biologic implausibility, Dr. Edwards noted (J Low Genit Tract Dis. 2019 Apr;23[2]:151-60.) Laser treatments for lichen sclerosus should not be used outside of clinical trials or without special arrangements for clinical governance, consent, and audit, according to a consensus document from the society.

“I mostly agree with that,” Dr. Edwards said. “But I now think that this is a reasonable thing to use when other treatments have been exhausted.”

Dr. Edwards and Dr. Venkatesan had no conflicts of interest. Dr. Haefner is an author for UpToDate.

Consider switching up treatment regimens for recurrent bacterial vaginosis

Article Type

Mon, 09/28/2020 - 10:00

Limited data are available to guide treatment of recurrent bacterial vaginosis, but behavioral changes and switching between approved medication regimens may help, according to a presenter at the virtual conference on diseases of the vulva and vagina, hosted by the International Society for the Study of Vulvovaginal Disease.

Dr. Debra L. Birenbaum

Investigational treatments – such as a live biotherapeutic product delivered vaginally or vaginal microbiome transplantation – could someday be additional options if they prove safe and effective. “The current research is emphasizing biofilm disruption and products that will reestablish normal acidic vaginal pH,” said Debra L. Birenbaum, MD, assistant professor of obstetrics and gynecology at Dartmouth-Hitchcock Medical Center in Lebanon, N.H.

As for home remedies, Dr. Birenbaum and another presenter at the conference, Cynthia Rasmussen, MD, urged caution during a panel discussion.

“I think the vagina knows its business, and the more you mess with it, the more you invite trouble,” said Dr. Rasmussen, director emerita of vulvovaginal services at Atrius Health in Burlington, Mass. For instance, tea tree oil, often cited as a home remedy, can be an allergen and very irritating.

“I want to know what women are using, but I try and dissuade them,” said Dr. Birenbaum. “I have to be careful what I say, because you’ll antagonize patients” if you come out strongly against home treatments. “I try to encourage them not to go by things they read on the Internet, because I think that’s where many people are finding their home remedies.”

When counseling patients, an analogy shared during the meeting – the vagina is a self-cleaning oven – may help get the point across. “I love the comment,” Dr. Birenbaum said. “I’ve never used that before. I’m going to start saying that.”
 

Possible causes and risk factors

Bacterial vaginosis, also known as vaginal dysbiosis, is the most common cause of discharge in women of reproductive age worldwide. Growth of a biofilm may cause the condition, which is characterized by a shift in vaginal flora from a Lactobacilli-dominant environment to one of other bacterial types.

Risk factors include douching, smoking, sex with an uncircumcised partner, and having multiple sexual partners. Bacterial vaginosis may be associated with various complications and infections, including increased risk of preterm delivery, postpartum endometritis, postabortal infection, Trichomonas, chlamydia, and HIV.

Unlike recurrent yeast, which is characterized by four or more episodes per year, recurrent bacterial vaginosis has no official criteria, Dr. Birenbaum said. However, recurrence of bacterial vaginosis “is extremely common,” she said. “Up to 30% of women with [bacterial vaginosis] may recur within 3 months, and up to 50% after 12 months.”
 

Lifestyle changes and treatments

Recommendations to use condoms, stop smoking, and not douche are important.

In addition, 11 treatment regimens for four drugs – metronidazole, clindamycin, tinidazole, or secnidazole – are available for the treatment of bacterial vaginosis. For recurrent cases, adjusting and switching between the drugs and modes of delivery may help. If a patient started with vaginal gel, they can try an oral medication, or vice versa.

“There’s very little data to guide the optimal therapy for this,” Dr. Birenbaum said. “All of this is worth a try to see if you can beat this before this becomes an ongoing issue.”

As an example of one possible regimen for recurrent bacterial vaginosis, Dr. Birenbaum suggested that a patient could complete a 2- to 4-week course of oral metronidazole instead of the usual 1-week course. The regimen could incorporate boric acid vaginal suppositories 600 mg nightly for 21 days, followed by metronidazole gel 0.75% (one applicator twice per week for 6 months).
 

 

 

New therapies may be on the horizon

In a randomized, double-blind, phase 2b trial published in the New England Journal of Medicine that included more than 220 participants, patients who received an investigational product containing Lactobacillus crispatus CTV-05 (Lactin-V) were less likely to have recurrent bacterial vaginosis at 12 weeks, compared with those who received placebo (30% vs. 45%).

A product in development known as TOL-463, a boric acid–based vaginal anti-infective enhanced with ethylenediaminetetraacetic acid, may be safe and effective, a phase 2 study published in Clinical Infectious Diseases suggests.

Investigators in the United Kingdom designed a trial to compare lactic acid gel and metronidazole, and the findings published in the Trials journal may clarify inconsistent results from prior studies.

Furthermore, preclinical research in Pathogens and Disease has identified cationic amphiphiles that might help fight the biofilm that is formed with Gardnerella vaginalis in patients with bacterial vaginosis, Dr. Birenbaum said.

Finally, an exploratory study in Israel published in Nature Medicine evaluated vaginal microbiome transplants in five patients, three of whom required repeat transplantation. Four patients had long-term remission, and one had a reduction in symptoms

Three-step approach may help relieve one of the itchiest vulvar conditions

Article Type

A three-step approach may help relieve itch in patients with lichen simplex chronicus, “one of the itchiest conditions that we ever see on the vulva,” an expert advised at the virtual conference on diseases of the vulva and vagina, hosted by the International Society for the Study of Vulvovaginal Disease.

For some patients, such as those with excessive sweating or underlying psoriasis, seeing a dermatologist may be beneficial, physicians at the meeting suggested.

Treatment should aim to optimize epithelial barrier function, reduce inflammation, and stop scratching, Lynette Margesson, MD, said in a lecture at the biennial meeting, which is held by the International Society for the Study of Vulvovaginal Disease (ISSVD). “With this condition, please look always for more than one problem.”

Lichen simplex chronicus is a thick, hyperkeratotic, firm, itchy rash that can develop on top of any dermatitis. “It doesn’t show up out of nowhere,” said Dr. Margesson, an obstetrician and gynecologist at Geisel School of Medicine at Dartmouth in Hanover, N.H. “It is because of chronic rubbing and scratching on top of something else.”

It may develop on top of atopic dermatitis, psoriasis, or contact dermatitis, as well as infection, lichen sclerosus, lichen planus, or neoplasia.

Lichen simplex chronicus is characterized by years of relentless itching, and patients may wake up at night scratching. The skin looks and feels leathery, and the condition can be localized or around the entire vulva. Heat, humidity, stress, and irritants may exacerbate the condition.

Patients often try to wash the rash away with scrubbers and cleansers, which only makes it worse, Dr. Margesson said.

To get patients better, improve barrier function, such as by controlling infections, reducing sweating, avoiding irritants, and stopping excessive hygiene. Immediate therapy may include soaks, cool compresses, and ointments.

A superpotent steroid taper (e.g., clobetasol 0.05% ointment), a prednisone taper, or intramuscular triamcinolone may reduce inflammation. Dr. Margesson usually uses clobetasol, although this treatment or halobetasol can burn if patients have open skin. In such cases, she uses prednisone or intramuscular triamcinolone.

Sedating medications may help patients stop scratching, especially at night. Hydroxyzine, doxepin, or amitriptyline 2-3 hours before bedtime can help. Scratching can be a form of obsessive-compulsive disorder, and a small dose of citalopram may help during the day. Patients with significant psychological factors can be difficult to manage and tend to relapse easily, Dr. Margesson said.

If lichen simplex chronicus recurs, test for infections and allergies. “Maybe they need a mild corticosteroid all the time, like 2.5% hydrocortisone to alternate with your superpotent steroid so you can use it longer without thinning the skin,” she suggested.

Although Dr. Margesson does not often treat hyperhidrosis, addressing excessive sweating can make a big difference for patients, she said.

If a gynecologist identifies a patient who may benefit from treatment of hyperhidrosis but has limited experience with medications for this condition, it might make sense to work with a dermatologist, Aruna Venkatesan, MD, chief of dermatology and director of the genital dermatology clinic at Santa Clara Valley Medical Center in San Jose, Calif., suggested during a panel discussion. Most dermatologists treat hyperhidrosis regularly, she said.

Dermatologists also may help treat patients with psoriasis who need systemic medication, Dr. Margesson said.

“In terms of ... doing the lab monitoring and knowing what side effects to look out for, your colleagues who use these medicines more are going to be more comfortable with that,” Dr. Venkatesan said. They also may have more experience navigating insurance denials to obtain a therapy. “Don’t think you are passing the buck to someone else. Sometimes that is the right thing to do, to get that help from someone else.”

A three-step approach may help relieve itch in patients with lichen simplex chronicus, “one of the itchiest conditions that we ever see on the vulva,” an expert advised at the virtual conference on diseases of the vulva and vagina, hosted by the International Society for the Study of Vulvovaginal Disease.

For some patients, such as those with excessive sweating or underlying psoriasis, seeing a dermatologist may be beneficial, physicians at the meeting suggested.
