Immunological features and factors associated with mucocutaneous bullous pemphigoid - a retrospective cohort study

BACKGROUND AND OBJECTIVES

The features of bullous pemphigoid (BP) patients presenting with mucosal lesions are not established. We aimed to elucidate the clinical and immunological features of BP patients with mucosal involvement, and to identify factors associated with mucosal lesions.

PATIENTS AND METHODS

A retrospective study encompassing all consecutive patients diagnosed with BP throughout the years 2009-2019 in a tertiary referral center.

RESULTS

The study encompassed 273 patients with BP, of whom 31 (11.4 %) presented with mucosal lesions. The oral mucosa was the most frequently affected mucosal surface (71.0 %), followed by the genital (25.8 %) and the nasal (22.6 %) mucosae. Relative to other patients with BP, patients with mucosal involvement had a more prominent palmoplantar involvement (67.7 % vs. 37.2 %; P = 0.001); lower seropositivity rate (18.2 % vs. 54.2 %; P = 0.027) and lower levels (29.3 ± 64.5 vs. 129.5 ± 304.4 U/ml; P = 0.016) of anti-BP230 autoantibodies; and decreased peripheral eosinophil counts (760.0 ± 638.6 vs. 1296.3 ± 1013.7; P < 0.001). Absence of anti-BP230 autoantibodies (OR, 5.32; 95 % CI, 1.07-26.32; P = 0.026) and lack of peripheral eosinophilia (OR, 4.31; 95 % CI, 1.14-16.39; P = 0.021) were associated with the presence of mucosal involvement in BP.

CONCLUSIONS

Mucosal involvement is present in a notable subgroup of patients with BP and is associated with the absence of both anti-BP230 antibodies and peripheral eosinophilia.

[Paediatric vulval clinic]

In 2008 a vulval clinic was established at the University Clinic of Schleswig Holstein, Campus Luebeck, Department of Dermatology. A total of 1227 patients were referred to the clinic between 2008 and October 2020, including 91 children (age range 1-13 years) and 17 adolescents (age range 14-17 years). The most common paediatric vulval conditions encountered were lichen sclerosus (33%), vulvitis (23%) and vulval psoriasis (7%). Quality of life was measured in 81 children using the paediatric version of the Dermatology Life Quality Index (DLQI). Of a maximum 30 points, the mean score was 7.2, confirming the association between vulval diseases and impaired quality of life in children and adolescents.

Glucocorticoid Receptor Beta and Its Prognostic Value on Treatment Response in Chronic Vulvar Dermatitis

BACKGROUND

Chronic vulvar dermatitis (CVD) is the most prevalent disease in gynecologic dermatology. The treatment mainly depends on topical glucocorticoids (TGC) but is challenged by insufficient treatment response. On a histological level, the upregulation of the glucocorticoid receptor β (GRβ), an inhibitor of the active glucocorticoid receptor α (GRα), is discussed as mechanism of glucocorticoid insensitivity.

OBJECTIVES

To analyze whether the expression of GRβ protein at baseline in keratinocytes may predict responsiveness to TGC in patients with CVD.

METHODS

In this retrospective cohort study, clinical and biological data of 25 women with a histological diagnosis of chronic vulvar eczema were analyzed. Randomization was done according to the responsiveness to TGC treatment (responsive vs. nonresponsive). Clinical data and the expression of GRβ in the immunohistochemical stained biopsies were examined.

RESULTS

Fifty-two percent of women with CVD were nonresponsive to TGC. GRβ was abundantly expressed in the cytoplasma of keratinocytes of the vulvar epithelium, but no difference in the level of expression was found among GC responsive and nonresponsive patients in the semiquantitative (p = 0.376) and quantitative analysis (p = 0.894).

CONCLUSION

GRβ is highly expressed in keratinocytes of the vulvar epidermis affected by CVD, but GRβ expression was not increased in patients nonresponsive to TGC compared to responsive patients. Thus, the failure mechanism in nonresponders still remains to be elucidated.

Algorithms for Managing Vulvovaginal Symptoms-a Practical Primer

PURPOSE OF REVIEW

To present a comprehensive systematic approach for diagnosing correctly the cause(s) of bothersome genital symptoms.

RECENT FINDINGS

We searched the PUBMED for practical clinical guidelines, written by a multidisciplinary team of healthcare providers directed for diagnosing bothersome genital symptoms. This search was performed by a professional information specialist using the keywords "vulvovaginal," "vulvar," "multidisciplinary diagnosis," "interdisciplinary consultation," and "vulvology." We found numerous publications defining the criteria for diagnosing specific disorders, but only a few publications presented a multidisciplinary clinical algorithm for diagnosing bothersome vulvovaginal symptoms. The authors, from three different specialities, gathered together (online), in aim to present a comprehensive systematic approach for accurate diagnosing of bothersome vulvovaginal symptoms. Six principles for accurately diagnosing a woman with bothersome genital symptoms were endorsed: (1) locate the discomfort (vulva, clitoris, vestibule, vagina, cervix, pelvis); (2) consider more than one entity; (3) evaluate each symptom separately (it is common to have more than one entity necessitating treatment for each); (4) use pH and wet mount microscopy; (5) obtain a follow-up visit in 2-4 weeks; (6) perform a biopsy for dermatological conditions that are resistant to treatment.

Clinical and epidemiological profile of patients attended in a vulvar clinic of the dermatology outpatient unit of a tertiary hospital during a 4-year period

BACKGROUND

Vulvar complaints are among the most frequent causes for a woman to visit a healthcare provider. The diseases of this area of the body may be a challenge to diagnose. In this study, we assess epidemiologic and clinical data of patients in an outpatient vulvar clinic in the dermatology department of a tertiary hospital.

METHODS

We performed an observational retrospective study of patients who attended our consultation service for vulvar diseases at the Dermatology Division at Hospital das Clínicas da Faculdade de Medicina da USP during a 4-year period. Data were obtained by patient medical records and by phone.

RESULTS

During the 4-year period under study, a total of 136 patients were treated in the outpatient service specialized in vulvar care. All patients were included in the study. The most frequent diagnoses were lichen sclerosus et atrophicus (64.7%), lichen planus (8.8%), and vitiligo (8%). We registered that 26.7% of the patients showed extravulvar involvement.

CONCLUSIONS

Women with vulvar diseases need specific care, considering not only genital aspects but also all skin changes. In this context, the dermatologist is a very well trained professional to take good and complete care of these patients. However, ideally vulvar clinics should have a multidisciplinary team.

[Inflammatory Diseases of the Vulva - a Dermatologist's Point of View]

Inflammatory Diseases of the Vulva - a Dermatologist's Point of View Abstract. Inflammatory vulvar diseases include a variety of disorders - many of which have a chronic course with significant morbidity. Diagnosis and especially treatment can be challenging for the clinician and warrant an interdisciplinary approach. This review covers the most common non-infectious and non-malignant vulvar diseases - from a dermatological point of view. The typical clinical symptoms, clinical appearances, treatment modalities of the main non-infectious vulvar diseases are highlighted; additionally, important dermatological differential diagnoses which should not be forgotten will be mentioned.

Potential delay in the diagnosis of vulvar cancer and associated risk factors in women treated in German gynecological practices

The goal of this study was to estimate a potential delay in the diagnosis of vulvar cancer and identify associated risk factors in women treated in gynecological practices in Germany. The current study sample included 1,652 women from 218 gynecological practices who received an initial diagnosis of vulvar cancer (ICD 10: C51) between January 2000 and December 2015 (index date). After applying several exclusion criteria, 505 non-cancer controls were matched (1:1) to 505 vulvar cancer cases based on age, health insurance status, and index date. The primary outcome was the delay in vulvar cancer diagnosis in women who had received an initial diagnosis of diseases of Bartholin's gland, inflammation of vagina and vulva, or other specified noninflammatory disorders of vulva, including atrophy, hypertrophy, and cyst. A logistic regression model was used to estimate the association between vulvar cancer and pre-defined diagnoses. The mean age was 60.8 years (SD = 15.6 years), and 4.8% of women had private health insurance coverage. Inflammation of vagina and vulva was diagnosed 328 days (SD = 95 days) prior to the detection of vulvar cancer. This delay was 186 days (SD = 196 days) in patients affected by diseases of Bartholin’s gland and 300 days (SD = 116 days) in those with other specified noninflammatory disorders of vulva including atrophy, hypertrophy, and cyst. The risk of vulvar cancer was positively associated with inflammation of vagina and vulva (OR = 2.28) and other specified noninflammatory disorders of vulva (OR = 5.39). The mean potential delay of vulvar cancer diagnosis ranged from 186 to 328 days.

[Vulvar diseases]

Vulvar diseases might cause problems in the differential diagnosis, because the clinical presentation of inflammatory, infectious and neoplastic disorders may be quite similar. Itching and pain as well as dysuria and dyspareunia are the most common symptoms of vulvar diseases. Inflammatory dermatoses like atopic and contact dermatitis, lichen planus, lichen sclerosus and atrophic vulvitis account for the majority of cases in specialized clinics. Furthermore, neoplastic conditions such as vulvar carcinoma, vulvar intraepithelial neoplasia (VIN) and vulvar Paget's disease have to be considered. Another frequent group are infections. Candida spp., herpes simplex viruses and human papilloma viruses are common pathogens. Additionally, vulvodynia is a typical problem that is sometimes difficult to treat. Because of the wide spectrum of clinical symptoms, cooperation with gynaecologists and psychosomatic specialists should be considered in difficult cases. The typical clinical presentations, their specific signs and symptoms, and pitfalls in the dermatological consultation are discussed.
