Treatment Options in Vulvar Lichen Sclerosus: A Scoping Review

Vulvar lichen sclerosus (VLS) is a chronic inflammatory disorder, which affects women of all ages. The aim of this review is to focus on first-line, second-line, and maintenance therapies as well as follow-up of women with VLS. With numerous controversies, we decided to conduct a scoping review on this subject. A review protocol was developed, and the Knowledge Resource Services website was used to run a search of articles pertaining to VLS with keywords “Vulvar,” “Vulval,” and “Lichen Sclerosus.” The search was limited to published data from the last 10 years, i.e., July 2009 onward, and researches published in English language. A total of 338 articles pertaining to VLS were obtained. Out of this, 62 were original articles related to management of VLS. Effective treatments such as high-potency topical steroids are now the standard of care and first-line treatment. Follow-up may be done every three to six months for the first two years and then at least yearly to ensure adequacy of treatment and encourage compliance. Long-term follow-up in specialist clinics is recommended for women who have persistent complaints, thickened skin, or history of neoplastic lesion. Monitoring young patients yearly is recommended as there are chances of recurrence.

Anogenital Pruritus - An Overview

Anogenital pruritus is defined as intense itching, acute or chronic, affecting the anal, perianal, perineal and genital skin, which is a dominant problem in the course of various cutaneous and systemic conditions. It is one of the common, extremely annoying symptom for which patients attend the Dermatology Outpatient Department (OPD). Anogenital skin is highly sensitive to soaps, perfumes, clothing and superficial trauma and it is more prone for itchy dermatoses as a result of warmth, friction, lack of aeration, sweating and occlusive inner garments. Anogenital pruritus is associated with a wide spectrum of diseases which includes localized infections, infestations, inflammatory dermatoses, allergic and irritant conditions, anorectal diseases, systemic causes, nutritional disorders, psychological and when the cause cannot be found out it is often termed idiopathic. Patients are highly reluctant in consulting the physician for anogenital itch in the early stage, they usually present at a later stage with either atypical manifestations or depigmentation and lichenification, secondary to constant scratching. They often resort to over the counter topical agents, particularly combination products which contain topical steroids. The irrational use of such products results in complications like skin atrophy, striae, incognito etc. A proper clinical history, clinical examination, investigations like scrapping for fungus and itch mite, skin biopsy, patch test and relevant blood investigations to rule out systemic conditions should be carried out, when needed, to arrive at an accurate diagnosis, before treating the patient.

Resolution of Chronic Vulvar Pruritus With Replacement of a Neuromodulation Device

Vulvar pruritus is typically associated with fungal, bacterial, and/or dermatological conditions that routinely resolve with the use of topical medications. Pruritus rarely becomes chronic in nature without a definable pathological diagnosis. However, when this occurs, management is difficult and has limited treatment options. Few cases have reported resolution of vulvar pain or discomfort with sacral neuromodulation implantation. We report a case in which a patient experienced chronic vulvar pruritus that was refractory to medical treatments and did not have a pathological diagnosis. A neurological etiology was suspected, and upon replacement of the patient's sacral neuromodulation device, complete resolution of the vulvar symptoms occurred.

Efficacy of topical pimecrolimus in the treatment of chronic vulvar pruritus: A prospective case series – a non‐controlled, open‐label study

BACKGROUND

Chronic vulvar pruritus has been a most distressing physical and sociologic disorder for many patients, as well as for their physicians. Potent topical steroids are the conventional therapy for this distressing condition. Side effects or steroid resistance can be encountered. A second-line therapy is required.

OBJECTIVES

A single-centre, non-controlled, open-label study was designed to assess the efficacy of topical pimecrolimus in the treatment of chronic vulvar pruritus.

METHODS

Fifteen married adult women with symptoms of vulvar pruritus > or =4 months were included in the study. The patients did not have any relief with topical steroids. There were no objective physical findings. Topical pimecrolimus 1% cream (Elidel cream, Novartis) was applied twice daily to the vulvar region. Patients were followed up 4 weeks later. After the trial was stopped, the patients remained in regular review for 3 months.

RESULTS

Thirteen patients tolerated pimecrolimus. They showed a clinical response within 2-4 weeks. Ten patients showed a complete response, three showed a partial response. After the trial had stopped, the patients with complete response were followed-up by telephone for another 3 months, and were found to be in remission.

CONCLUSIONS

We found that topical pimecrolimus provides relief for chronic vulvar pruritus. Pimecrolimus can be chosen as the second-line therapy in patients with vulvar pruritus.

An approach to the treatment of anogenital pruritus

The anogenital area is a common location for pruritic complaints. Specific terms for chronic itch in this location have included pruritus vulvae, pruritus ani, lichen simplex chronicus, and neurodermatitis. A male counterpart to pruritus vulvae, pruritus scroti, is less common. Acute anogenital pruritus is usually caused by infections or contact dermatitis. In chronic pruritus, inflammatory dermatoses and malignancies must be ruled out. In idiopathic anogenital pruritus or neurodermatitis, the skin findings should be limited to lichenification and excoriations. Skin findings may be entirely absent. When treating anogenital pruritus, topic irritants and potential sensitizers must be eliminated. Cleansing and toilet habits must be addressed. A short course of a high-potency topical steroid should bring moderate to complete relief. Sedating antihistamines may limit nighttime symptoms. In some patients, psychotropic agents are required to achieve adequate sedation. Antidepressants may be required in patients refractory to treatment or with underlying psychiatric disorders.

Pruritus vulvae in prepubertal children

BACKGROUND

Vulvar pruritus is a common complaint in females of all ages. However, little has been published on pruritus vulvae in children as a primary symptom.

OBJECTIVE

Our purpose is to review the causes and treatments of vulvar pruritus in prepubertal girls and to retrospectively evaluate the causes and outcomes of the premenarchal children we studied.

METHODS

The records of 44 premenarchal girls with vulvar pruritus were reviewed, and follow-up interviews were performed by telephone.

RESULTS

Thirty-three patients (75%) had nonspecific pruritus. Lichen sclerosus, bacterial infections, yeast infection, and pinworm infestation were seen in a minority of patients. At follow-up, pruritus had cleared in 15 patients, been alleviated in 13, and remained the same in 4.

CONCLUSION

Most of our patients had nonspecific pruritus, which was alleviated by or cleared with better hygiene and avoidance of irritants. In prepubertal girls, poor hygiene and irritants such as soap are major contributors to pruritus vulvae. All patients may benefit from following hygienic measures and irritant precautions in addition to specific therapy directed at underlying causes.
