A Longitudinal Multiinstitutional Study of Vulvar Lichen Sclerosus: From Childhood to Perimenopause.

OBJECTIVE: The main outcome of this study was the evaluation of clinical characteristics, comorbidities, and therapeutic approaches in patients with vulvar lichen sclerosus (VLS) aged from childhood to perimenopause. Secondly, it was intended to compare these characteristics according to the menarchal status. METHODS: Patients less than 45 years of age with a diagnosis of VLS from January 2002 to June 2022 in 10 referral centers were included in this retrospective longitudinal study. The univariate analysis compared the dependent variables according to menarchal status. RESULTS: One hundred eighty-six patients met the inclusion criteria. At diagnosis, between 25% and 40% of premenarchal patients reported signs related to subepithelial hemorrhage. A significantly greater presence of bleeding ( p < .005), easy bruising ( p = .028), fissures ( p = .008), petechiae/splinter hemorrhages ( p < .001), and bleeding/blistering or open sores ( p = .011) was observed in premenarchal patients with respect to the postmenarchal group. The perineum ( p = .013) and the perianal region ( p < .001) were significantly more involved in the premenarchal group. Topical calcineurin inhibitors were more used in the premenarchal population ( p = .004), whereas vitamin E oil and moisturizers were more used in the postmenarchal population ( p = .047). CONCLUSIONS: Vulvar lichen sclerosus is a chronic condition that can cause vulvar changes that result in severe morbidity and affects sexual function and quality of life, even before menopause. Vulvar lichen sclerosus continues to be misdiagnosed in this population. This may lead to an average delay from symptom onset to diagnosis. Evaluating clinical manifestations of VLS in premenarchal and postmenarchal age allowed us to find different clinical characteristics between the 2 periods suggestive of the diagnosis.

Therapeutic Efficacy of a Coriolus versicolor-Based Vaginal Gel in Women with Cervical Uterine High-Risk HPV Infection: A Retrospective Observational Study.

INTRODUCTION: A Coriolus versicolor-based vaginal gel is available for treating women with cervical uterine high-risk human papillomavirus (HPV) infection through re-epithelizing and re-balancing microbiota actions. METHODS: A longitudinal retrospective observational study was performed to evaluate efficacy and safety of the gel. Women treated with Coriolus versicolor-based vaginal gel were compared with women not treated with the gel. Both groups were monitored for HPV infection by an HPV DNA test, Pap smear (cytology) and colposcopy at baseline and after 6 months. RESULTS: Overall, 183 high-risk HPV positive women were enrolled (97 treated and 86 controls). After 6 months, the HPV DNA test became negative in 67.0% versus 37.2% of treated and controls, respectively (p < 0.0001). Furthermore, 76.1% versus 40.8% registered a colposcopy improvement (p = 0.0005) and 60.4% versus 40.8% showed a remission (p = 0.05), for treated versus controls, respectively. Regarding to cytology, 78.5% of treated versus 37.7% of controls registered an improvement, while 70.8% of treated versus 34.8% of controls had a remission (p < 0.0001 for both variables). At multivariate analyses adjusted for age, smoking habit, and use of estroprogestinic pill, compared to controls, women treated with the gel showed a significantly higher likelihood to experience the clearence of HPV DNA (OR 4.81; 95% 2.43-9.53), and remission at colposcopy (OR 2.30; 95% 1.00-5.31), and cytology (OR 5.13; 95% 2.40-10.96) at 6 months. No adverse event was reported during the follow-up. CONCLUSIONS: The use of a Coriolus versicolor-based vaginal gel in high-risk HPV patients is safe and effective based on all examined tests.

Ellagic acid and Annona muricata in the chemoprevention of HPV-related pre-neoplastic lesions of the cervix.

Ellagic acid is a phenolic compound naturally present in nuts and berries. Several studies have demonstrated that this bioactive compound has antioxidant, chemopreventive and antiviral activity. Annona muricata is a type of fruit tree with a long history of traditional use. A number of properties have been attributed to different parts of the plant, including anticancer and antioxidant activities. In the current study, a complex based on ellagic acid, Annona Muricata and antioxidant factors (an ellagic acid complex) was administered to a group of human papilloma virus (HPV) infected women with and without cervical lesions, for 12 months. Its effect on HPV clearance and cervical cytological outcomes was assessed and a group of women with the same clinical features who did not receive the ellagic acid complex served as a control. A positive correlation was observed between intake of ellagic acid complex and negative Pap test following 6 and 12 months of treatment (χ2 test: 0.041 and 0.014, respectively). Women treated with the ellagic acid complex were less likely to be diagnosed with an abnormal Pap smear at 6 months [Odds ratio (OR): 0.39; 95% confidence interval (CI) 0.14-1.06] and 12 months (OR: 0.35; 95% CI 0.13-0.89), compared with the control group. After adjusting for confounding factors including age and smoking habit, this association remained significant. No effect was observed on HPV clearance or viral integration. The data from the current study suggest a protective effect of the ellagic acid complex on cervical cells, possibly through apoptosis, cell cycle arrest and repair mechanisms.

Microbiological Infections in Women With Cervical Cytological Reports of Atypical Squamous Cells of Undetermined Significance.

OBJECTIVE: To study the role of cervicovaginal infections in women with cytological reports of atypical squamous cells of undetermined significance (ASC-US). MATERIALS AND METHODS: The study included 220 women admitted to the Clinic of Microscopy, Cervicovaginal and Vulvar Pathology of the Department of Gynecology and Obstetrics of the Tor Vergata University Hospital, Rome, Italy, enrolled between October 2012 and July 2013. RESULTS: Among the enrolled women, 105 women (47.7%) had ASC-US cytology, whereas 115 women (52.3%) had negative cytology. Microscopy showed infections more frequently in women with ASC-US than in those with negative cytology: 70.5% (74/105) vs 36% (41/115); p < .001. Cocci were present in 73.3% (77/105) of the women with ASC-US and in 43.5% (50/115) of those with negative cytology; p < .001. According to Ison score, 84% (88/105) of ASC-US was grade 0 vs 22% (25/115) of negative cytology, p < .001. Human papillomavirus was detected in 35% of the women with ASC-US. A statistically significant correlation between high pH and vaginal infections was found in women aged 20 to 29 (p = .003) and those 50 years or older in both cytological report groups; p < .001. CONCLUSIONS: Cervicovaginal infections are associated with a cytological report of ASC-US. Direct microscopy of vaginal specimens allowing immediate evaluation of the vaginal microflora and infectious agents may be a useful tool in managing women with cytological reports of ASC-US.

Human papillomavirus molecular testing in women with low grade cervical lesions: experience from an Italian hospital.

BACKGROUND: In recent years, efforts have been made to identify molecular markers as potential screening tools in the early detection of cervical cancer precursors. PATIENTS AND METHODS: One-hundred-eighty-two women admitted to the Colposcopy Unit of Tor Vergata University Hospital were enrolled in this study. The inclusion criteria were: i) Pap test with atypical squamous cells of undetermined significance (ASCUS) or low-grade squamous intraepithelial lesion (LSIL); ii) normal cytology but human papillomavirus (HPV) DNA test positive for at least one of the most frequently detected five high-risk HPV types (16, 18, 31, 33 and 45). HPV DNA was detected with the HPV Sign kit and the type was assigned by pyrosequencing using the PyroMark ID System. E6/E7 transcripts of the high-risk HPV types 16, 18, 31, 33 and 45 were detected by the NucliSense EasyQ HPV kit. RESULTS: Overall, 90 (49.5%) patients were HPV-DNA negative, whereas 92 (50.5%) were HPV-DNA positive. Single infections were detected in 55 women: HPV 16 ranked first (56.4%), followed by HPV 18 (21.8%), HPV 31 (9%), HPV 33 (7.3%), and HPV 45 (5.5%). Co-infections were detected in 37/92 (40.2%) positive cases; HPV 16 was detected most frequently (27/37), followed by HPV 18 and 31. All patients underwent HPV RNA testing: 47/182 (25.8%) tested positively while 135/182 (74.2%) were negative. HPV 16 E6/E7 transcripts was the most frequently detected. CONCLUSION: Detection of HPV E6/E7 oncogenic transcripts may be used as a molecular biomarker in women with ASCUS or LSIL to help identify women at risk of disease progression.

New site of modification of 23S rRNA associated with clarithromycin resistance of Helicobacter pylori clinical isolates.

Resistance of Helicobacter pylori to clarithromycin occurs with a prevalence ranging from 0 to 15%. This has an important clinical impact on dual and triple therapies, in which clarithromycin seems to be the better choice to achieve H. pylori eradication. In order to evaluate the possibility of new mechanisms of clarithromycin resistance, a PCR assay that amplified a portion of 23S rRNA from H. pylori isolates was used. Gastric tissue biopsy specimens from 230 consecutive patients were cultured for H. pylori isolation. Eighty-six gastric biopsy specimens yielded H. pylori-positive results, and among these 12 isolates were clarithromycin resistant. The latter were studied to detect mutations in the 23S rRNA gene. Sequence analysis of the 1,143-bp PCR product (portion of the 23S rRNA gene) did not reveal mutation such as that described at position 2142 to 2143. On the contrary, our findings show, for seven isolates, a T-to-C transition at position 2717. This mutation conferred a low level of resistance, equivalent to the MIC for the isolates, selected using the E-test as well as using the agar dilution method: 1 micro g/ml. Moreover, T2717C transition is located in a highly conserved region of the 23S RNA associated with functional sites: domain VI. This fact has a strong effect on the secondary structure of the 23S RNA and on its interaction with macrolide. Mutation at position 2717 also generated an HhaI restriction site; therefore, restriction analysis of the PCR product also permits a rapid detection of resistant isolates.
