The role of multiple high-risk human papillomavirus infection on the persistence recurrence of high-grade cervical lesions after standard treatment: A systematic review and a meta-analysis.

INTRODUCTION: The role of multiple high-risk human papillomavirus (HR-HPV) infections on the occurrence of persistence/recurrence of high-grade squamous intraepithelial lesion (HSIL) after conization/surgery for cervical intraepithelial neoplasia was evaluated. MATERIAL AND METHODS: A systematic search of Pubmed/Medine, Scopus, Cochrane databases from inception to June 30, 2023 was performed. Three reviewers independently screened the abstracts of the selected studies and extracted data from full-text articles. The data were subsequently tabulated and compared for consistency. The bias associated with each included study was evaluated according to the OSQE method. PROSPERO registration number CRD42023433022. RESULTS: Out of 1606 records screened, 22 full text articles met the inclusion criteria. A total of 8321 subjects treated (loop electrosurgical excision, laser or surgery) because of HSIL were followed-up and included in the meta-analysis. The pooled prevalence of overall persistence and/or recurrence was 17.6 (95% CI: 12.3-23.5) in multiple and 14.3 (95% CI: 10.1-19.2) in single HR-HPV infections detected shortly before or at surgery. The pooled rate of multiple HR-HPV infections was 25% (95% CI: 20.4-30). The odds ratio of histologically confirmed HSIL persistence and/or recurrence was significantly higher (OR: 1.38, 95% CI:1.08-1.75, p = 0.01, heterogeneity = 39%) among multiple than single HR-HPV infections. Increased risk of HSIL persistence/recurrence was more marked among studies with multiple HR-HPVs prevalence ≥25% (12 studies, N = 3476) (OR: 1.47, 95% CI: 1.18-1.84, heterogeneity = 0%) and in those evaluating true histologically confirmed recurrence after at least 6 months of negative follow-up (9 studies, N = 5073) (OR: 1.67, 95% CI: 1.17-2.37, heterogeneity = 37%). Multiple HR-HPVs infection detected during follow-up visits had no effect on the risk of recurrence although the number of included studies was small (4 studies, N = 1248) (OR: 0.98, 95% CI: 0.68-1.39, heterogeneity = 0%). The risk of bias was rated as high in 10 and low-moderate in 12 studies, respectively. In subgroup analysis, the risk of bias of the included studies (low/moderate vs. high), had a small, although not significant effect on the odds ratios of persistence/recurrence of HSIL (OR: 1.57, 95% CI: 1.23-2 for low-moderate risk of bias and OR: 1.06, 95% CI: 0.65-1.75 for high risk of bias; p-value for subgroup differences = 0.17). CONCLUSIONS: Multiple HR-HPVs infections at the time of standard treatment of HSIL entail a small but significant increased risk of persistence/recurrence of HSIL and should be taken into account in the follow-up plan.

The role of neutrophil-lymphocytes ratio (NLR) in the prognosis of CIN2+ 2 recurrence after excisional treatment.

OBJECTIVES: The main risk factor involved in CIN2+ recurrence after treatment is the HPV persistent infection. The dysregulation of the immune system permits only HR-HPVs to become persistent infections, to promote cancer development and to increase the risk of recurrence after treatment. Therefore, there is a shift to a Th2-type cytokine pattern during the carcinogenesis pathway; for this reason, the neutrophil-lymphocytes ratio (NLR) could be a marker of this immunological change. The study aims to analyse the predictive role of NLR in the recurrence of High-grade CIN (CIN2+) after excisional treatment in a real-world life setting of patients treated for CIN2+ Design: cross-sectional study Participants/Materials, Setting, Methods: We examined a retrospective database of 444 patients, who attended the Colposcopy Service of our Department from 2011 to 2020 due to an abnormal screening pap smear and we compared the clinical characteristics to NLR performed at the time of diagnosis. All analysed patients were treated according to an established protocol (colposcopy every 6 months for the first two years, and every year for the over three years,) and HPV-DNA test and cervical biopsy were performed at entry and the end of follow-up. All patients underwent a blood sample examination, including complete white blood cell counts and collecting neutrophil and lymphocyte values expressed as 103/ml. Results The sensitivity (SE) and specificity (SP) of the NLR cut-off point of 1.34 for the diagnosis of CIN2+ recurrence were 0.76 and 0.67, respectively. We found that CIN2+ recurrences were significantly higher in patients with NLR < 1.34 (3.7% vs. 0.6%, p = 0.033) and the 5-year recurrence-free survival was higher in patients with NLR ≥ 1.34 (97% vs. 93%, p=0.030). Limitations First, the retrospective analysis and low incidence of recurrence may limit the conclusions. Second, for the retrospective design of the study, we did not take into consideration the patient's comorbidities and habits (smoking), that may influence the NLR. On the other hand, the median duration of follow-up in our study was 26 months (IQR 22-31), which fully reflects the incidence of recurrences. Conclusions It is well known that CIN2+ lesions are sustained by deregulation of the immune system caused by persistent HPV infection, which may lead to cervical cancer. Among the actors underlying dysregulation of immunity, lymphocytes are involved in the permission of persistent infection and for this reason, NRL could be a reliable and cost-effective biomarker in predicting the risk of recurrence, especially for high-grade cervical lesions.

Pediatric Hemangiomas in the Female Genital Tract: A Literature Review.

BACKGROUND: Hemangiomas are aberrant proliferations of blood vessels and the most frequent benign pediatric soft tissue tumors. Although they are common, genital localization is rare. This study aimed to assist doctors in the diagnosis, management, and treatment of pediatric vulvovaginal hemangiomas by conducting a review of the literature. METHODS: We conducted a literature review including papers published between August 2009 and May 2023. RESULTS: While most hemangiomas are usually indolent and resolve with time, in some cases, especially cervicovaginal and uterine ones, they might present with severe symptoms like heavy bleeding and need further instrumental investigation for diagnosis, like CT or MRI. As for the treatment, many options are available, with medical therapy or expectant management being the first choice. CONCLUSIONS: Vulvovaginal pediatric hemangiomas are rare and require more research on how to detect and manage these lesions, especially the symptomatic and the psychologically impacting ones. For the time being, treatment should be personalized based on the patient's situation and clinician's expertise.

Neutrophil to lymphocytes ratio in deep infiltrating endometriosis as a new toll for clinical management.

Several mechanisms, including altered local and systemic immune system, apoptosis, and new angiogenesis, are responsible for the development and progression of endometriosis. Over the years many markers have been studied, like CA 125 and, recently, neutrophil-to-lymphocyte ratio (NLR). This tool is cost-effectiveness and non-invasiveness as a marker of systemic inflammatory diseases. The aim of this study is to assess the role of NLR in the real-life management of patients with endometriosis in order to evaluate the possible association between this value and symptoms. We performed a retrospective analysis of 199 premenopausal women affected by endometriosis, from January 2013 to December 2020, evaluating the characteristics of disease, the symptoms and the NLR. Analyzing the neutrophiles, the mean ± SD value was 6.1 ± 4.5 × 103/ul, while for lymphocytes mean ± SD value was 1.8 ± 0.7.NLR was categorized according to its median value (> 2.62 vs ≤ 2.62). The comparison between NLR values and CA 125, endometriosis stage, dysmenorrhea and presence of chronic pelvic pain, adjusting for previous therapy did not find a significant association. An interesting result, although not significant, was the association between NLR and chronic pelvic pain (OR = 1.9). In the sub-group of patients without previous therapy this association is even stronger (OR = 4.8, 95% CI 0.5-50.2, p = 0.190). The link between NLR and chronic pelvic pain can provide a further hint to the clinician even when taking symptoms into account to develop a particular therapeutic treatment related to the various expressions of NLR. Finally, NLR may enable the creation of customized follow-up protocols that divide patients into high- and low-risk categories for endometriosis recurrence.

Retrospective Investigation of Human Papillomavirus Cervical Infection and Lymphoma Incidence: A Clinical and Pathological Evaluation.

OBJECTIVE: Human papillomavirus (HPV) persistence is considered the main risk factor for neoplastic progression, and evidence suggests that regulatory T cells play an important role in the failure of viral elimination. Regulatory T cells may be involved in maintaining a microenvironment favourable for viral persistence and neoplasticity, through a deregulation of the local immune response. The association between altered immune function and the development of chronic infections, cancer (solid and haematological), and autoimmune diseases is documented in the literature. The purpose of this retrospective analysis was to evaluate the possible correlation between HPV cervical infection and lymphoma incidence in women attending colposcopy due to an abnormal Pap smear during a period of 15 years. DESIGN: This is a cross-sectional study. PARTICIPANTS: We investigated retrospectively the incidence of haematological diseases in women aged 21-84 with an abnormal Pap smear who referred to our centre between 2004 and 2019. SETTING: This study was conducted at the university hospital. METHODS: In our analysis, we included women with diagnoses of HL and NHL after the detection of abnormal Pap smears and HPV infections. We excluded patients with a diagnosis of lymphoma preceding the date of the abnormal Pap smear and HPV test. RESULTS: We divided the patients into two groups in order to analyse the standard incidence ratio (SIR): HL patients (19/7,064, 0.26%) and NHL patients (22/7,064, 0.31%). In our sample, we reported a significant risk of developing lymphoma compared to the general population, both for HL and NHL disease, at age <45 years. Regarding HL, the SIR of disease in women <45 years was 4.886 (95% CI 2.775-9.6029) and in women between 45 and 59 years was 2.612 (95% CI 0.96-7.108804). On the other hand, for NHL in women <45 years, we reported an SIR of about 3.007 (95%, CI 1.273-7.101575), in women aged 45-59 years, the SIR was 4.291 (95% CI 2.444-7.534399), and in women aged 60-74 years, the SIR was 3.283 (95% CI 1.054-10.22303). LIMITATIONS: This retrospective analysis was conducted in a single centre in Northern Italy and did not consider all interregional differences existing in the country in terms of HPV genotypes, ethnicity, and population characteristics. Regarding the analysis of SIR for HL and NHL, we did not divide the disease into subtypes because of the small sample of cases. Finally, we considered in our analysis only women with an abnormal Pap smear and not the general population. CONCLUSIONS: Women with chronic and persistent HPV infections may have a higher relative risk of developing lymphoma. This possible association may be caused by the deregulation of the immune system response against HPV and the failure of viral clearance, especially in younger women.

Lipschütz Ulcer and SARS-CoV-2: What We Currently Know?

BACKGROUND: In recent years, several interesting case reports have been published which describe the possible role of SARS-CoV-2 infection or vaccination in the etiopathogenesis of Lipschütz ulcer. Our aim is to analyze this association and provide a rapid algorithm that is of support to gynecologists and dermatologists both in the diagnosis and in setting up the therapy. To do so, in this paper, we describe an interesting case of acute vulvar ulcer triggered by SARS-CoV-2 infection and review the related literature. METHODS: We conducted a literature review including papers published between October 2021 and April 2023, and we described the case of a patient referred to our clinic with Lipschütz ulcer and SARS-CoV-2 infection. RESULTS: In almost all cases analyzed, a correlation with SARS-CoV-2 infection or vaccination was found; ulcers usually manifest after 2 to 4 weeks and are associated with flu-like symptoms. A concordance in review papers, as well as in our case report, was also found about the treatment, which is mainly symptomatic. CONCLUSIONS: Previous infection or vaccination for SARS-CoV-2 should be included as possible etiopathogenetic factors in the onset of Lipschütz ulcer.

Aromatase inhibitors in the pharmacotherapy of endometriosis.

INTRODUCTION: Endometriosis is a benign chronic inflammatory disease responsible for debilitating pain and decreased quality of life. The traditional treatment is based on estroprogestins, progestins, GnRH analogs, and surgery. Recently, aromatase inhibitors (AIs) demonstrated good efficacy in controlling symptoms and size of endometriotic implants, mostly because they suppress extraovarian estrogen synthesis, which can enhance the hypoestrogenic state ameliorating symptoms of endometriosis. AREAS COVERED: Phase I, II, III and IV trials, on the use of AIs used for the treatment of endometriosis, have been retrieved. The pharmacokinetics and pharmacodynamics of third-generation non-steroidal AIs have also been investigated. A MEDLINE search has been performed using the following MeSH keywords: 'endometriosis,' aromatase inhibitors,' 'therapy,' and 'treatment'. The timeframe was from 2010 up to November 2022 including reviews, systematic reviews, reports, case series, and retrospective or prospective trials. EXPERT OPINION: AIs have shown good clinical efficacy in combination with hormonal therapy in disease control, and they represent a promising second-line therapy in selected patients, yet more research is needed on alternative drug delivery systems and better control of adverse effects. In postmenopausal women in which surgery is contraindicated, AIs represent an excellent treatment option. Their application in routine clinical practice remains limited by adverse effects.

Microbiota Ecosystem in Recurrent Cystitis and the Immunological Microenvironment of Urothelium.

Urinary tract infections (UTIs) represent one of the most frequent low genital tract diseases in the female population. When UTIs occur with a frequency of at least three times per year or two times in the last six month, we speak of recurrent UTI (rUTI) and up to 70% of women will have rUTI within 1 year. It was previously thought that antibiotic resistance was principally responsible for the recurrence of UTIs, but nowadays new diagnostic technologies have shown the role of microbiota in the pathophysiology of these diseases. Much research has been conducted on the role of gut microbiome in the development of rUTI, while little is known yet about vaginal and urinary microbiome and the possible immunological and microscopical mechanisms through which they trigger symptoms. New discoveries and clinical perspectives are arising, and they all agree that a personalized, multi-modal approach, treating vaginal and urinary dysbiosis, may reduce rUTIs more successfully.

Risk Analysis Stratification of CIN 2+ Development in a Cohort of Women Living with HIV with Negative Pap Smear and HR-HPV Test during a Long-Term Follow-Up.

BACKGROUND: Women living with Human Immunodeficiency Virus are at higher risk of cervical cancer and precancer compared to women without HIV infection. The aim of the study is to evaluate the risk factors for the development of CIN2+ in a cohort of WLWH with negative colposcopy and cytology during a long follow-up period. METHODS: We enrolled, in a multicentric retrospective cohort study, WLWH who attended the colposcopic services from 1999 to 2019. Patients with a normal Pap smear, a negative HR-HPV test, and at least one year of follow-up were considered for the anlysis. RESULTS: The five-year cumulative incidence of histologically confirmed HSIL was 8.3% (95% CI = 2.6-13.6) among subjects with a CD4+ cell count of <200 cells/µL at any visit and 2.1% (95% CI = 0.7-3.4, p = 0.001) in women with a CD4+ cell count of persistently >200 cells/µL. In women with persistent HR-HPV infection, the five-year cumulative incidence of CIN 2+ was 6% (95% CI = 1.6-10.2) versus 2% (95% CI = 0.4-3.6, p = 0.012) in women without HPV infection. An HIV viremia of >200 copies/mL, a CD4+ cell count of <200 cells/µL, persistent HR-HPV infection, and smoking ≥10 cigarettes/day were all independent and statistically significant risk factors associated with the development of CIN2+ during follow-up. CONCLUSIONS: WLWH with good immune status and negative Pap smear and HR-HPV test have a low risk for CIN2+.

Low-Grade Cervical Intraepithelial Neoplasia (CIN1) Evolution: Analysis of Opportunistic Preventive Vaccination Role.

BACKGROUND: Low-grade cervical lesions have a high percentage of clearance in young women, even if 71-82% of low-grade intraepithelial lesion/atypical squamous cells of undetermined significance (LSIL/ASCUS) reported a High-Risk Human Papillomavirus (HR-HPV) infection, which correlates with an increased risk of Cervical Intraepithelial Neoplasia (CIN)2+. The immunogenic effect of the anti-HPV vaccine appears to be significant. The aim of the study is to evaluate the effect, two years after the diagnosis, of the anti-HPV preventive vaccination on patients with low-grade cervical lesions. METHODS: We collected clinical, colposcopic, histological, and virological data from patients aged 21-45 years who attended the colposcopy service of the department of Obsetrics and Gynecology of IRCCS Foundation Policlinico San Matteo, Pavia, Italy. In the 2005-2019 period and had a low-grade pap-smear. RESULTS: We enrolled 422 women consecutively, divided into two groups (vaccinated and not vaccinated) for the retrospective analysis. The rate of persistence and progression of CIN were higher in the not-vaccinated group (p = 0.019). The relative risk (RR) to develop CIN2+ during follow-up vs. the the CIN1 persistence was 1.005 (95% Confidence Interval-CI 0.961-1.051) vs. 0.994 (95% CI 0.994-1.018) for age, 3.472 (95% CI 1.066-11.320) vs. 1.266 (95% CI 0.774-2.068) for non-vaccinated, 0.299 (95% CI 0.088-1.018) vs. 0.518 (95% CI 0.242-1.109) for HIV status negative, respectively. Analyzing the time to negativity, the odds ratio (OR) was 1.012 (95% CI 1-1.024) for age and 1.591 (95% CI 1.223-2.069) for vaccination; on the other hand, considering the relationship between the time to negative and the HPV genotypes contained in the 9-valent HPV vaccines, the OR was 1.299 (95% CI 1.026-1.646) for at least one of these at recruitment and 0.631 (95% CI 0.471-0.846) at follow-up. Furthermore, the presence of at least one of the HPV genotypes targeted by the HPV nonavalent vaccine is a key indicator of the risk of progression to CIN2+: OR was 3.443 (95% CI 1.065-11.189) for the presence of at least one HPV genotype at enrollment and 5.011 (95% CI 1.899-13.224) for the presence of at least one HPV genotype at follow-up, respectively. CONCLUSIONS: We reported in a retrospective study the benefit of anti-HPV vaccination in promoting negativity and increasing low-grade cervical lesions regression.

Genital perception and vulvar appearance after childbirth: a cohort analysis of genital body image and sexuality.

PURPOSE: The mode of delivery influences the genital image and perception, especially regarding the effects of delivery on sexual life and intercourse. The current literature has not adequately investigated the relationship between delivery and genital appearance. The aim of the study is to determine whether the mode of delivery changes the genital perception of the woman and, in doing so, influences their acceptance. The secondary aim is to analyze the impact of genital appearance on sexuality. METHODS: A prospective survey regarding genital appearance and the impact of delivery mode on vulvar perception was conducted in patients 6 weeks after childbirth. We enrolled 365 women for evaluation, divided into three groups: spontaneous vaginal delivery (SVD 295 women 80.82%), operative vaginal delivery (OVD 36 women 9.86%) and cesarean section (CS 34 women 9.31%). RESULTS: There was a statistically significant difference in the frequency of vulva inspection and in the perception of genital modifications among the groups (p < 0.001 and p < 0.001, respectively). The perception of overall genital modifications was significantly correlated with the frequency of inspection (p = 0.004) and the delivery mode (p = 0.0002). CONCLUSION: Mode of delivery may influence the genital perception and appearance of genitalia without a decrease of sexual life and daily activity in childbirth.

The Complex Interplay between Vaginal Microbiota, HPV Infection, and Immunological Microenvironment in Cervical Intraepithelial Neoplasia: A Literature Review.

BACKGROUND: in recent years, many studies were carried out to explore the role of vaginal microbiota in HPV infections and cervical intraepithelial neoplasia (CIN) progression. The aim of this study was to conduct a review of the literature to analyze the interaction between the vaginal microbiota, the CIN, and the immunological response. METHODS: we performed a literature search, considering papers published between November 2015 and September 2021. RESULTS: despite significant evidence suggesting a role of vaginal microbiota in the pathogenesis of HPV-related lesions, some studies still struggle to demonstrate this correlation. However, the vaginal microbiota of HPV-positive women shows an increased diversity, combined with a reduced relative abundance of Lactobacillus spp. and a higher pH. In cervical dysplasia progression, a strong association is found with new bacteria, and with the deregulation of pathways and hyperexpression of cytokines leading to chronic inflammation. CONCLUSIONS: in HPV progression, there is a strong correlation between potential biomarkers, such as Sneathia and Delftia found in community state types IV and II, and chronic inflammation with cytokine overexpression. Better analysis of these factors could be of use in the prevention of the progression of the disease and, eventually, in new therapeutic strategies.

New Perspectives in Therapeutic Vaccines for HPV: A Critical Review.

Human Papillomavirus is the main cause of cervical cancer, including squamous cell carcinoma of the oropharynx, anus, rectum, penis, vagina, and vulva. In recent years, considerable effort has been made to control HPV-induced diseases using either prophylactic or therapeutic approaches. A critical review of the literature about the therapeutic Human Papillomavirus vaccine was performed to analyze its efficacy in the treatment of female lower genital tract lesions and its possible perspective application in clinical practice. The most important medical databases were consulted, and all papers published from 2000 until 2021 were considered. We retrieved a group of seven papers, reporting the role of anti HPV therapeutic vaccines against the L2 protein in the order of their efficacy and safety in female lower genital tract disease. In addition, the immune response due to vaccine administration was evaluated. The development of therapeutic vaccines represents an interesting challenge for the treatment of HPV infection of the lower genital tract. Literature data underline that the L2 protein may be an interesting and promising target in the development of therapeutic HPV vaccines, but the possible strengths and the unclear longevity of L2 immune responses are factors to be considered before clinical use.

Human Papillomavirus Cervical Infection: Many Ways to a Single Destination.

Human papillomavirus (HPV) infection represents the most diffuse sexually transmitted disease of the lower genital tract, with an estimated risk of infection in the general population of 80% over the course of the lifetime [...].
