RESUMO

The risk of infection associated with immunomodulatory or immunosuppressive disease-modifying drugs (DMDs) in patients with multiple sclerosis (MS) has been increasingly addressed in recent scientific literature. A modified Delphi consensus process was conducted to develop clinically relevant, evidence-based recommendations to assist physicians with decision-making in relation to the risks of a wide range of infections associated with different DMDs in patients with MS. The current consensus statements, developed by a panel of experts (neurologists, infectious disease specialists, a gynaecologist and a neuroradiologist), address the risk of iatrogenic infections (opportunistic infections, including herpes and cryptococcal infections, candidiasis and listeria; progressive multifocal leukoencephalopathy; human papillomavirus and urinary tract infections; respiratory tract infections and tuberculosis; hepatitis and gastrointestinal infections) in patients with MS treated with different DMDs, as well as prevention strategies and surveillance strategies for the early identification of infections. In the discussion, more recent data emerged in the literature were taken into consideration. Recommended risk reduction and management strategies for infections include screening at diagnosis and before starting a new DMD, prophylaxis where appropriate, monitoring and early diagnosis.

RESUMO

BACKGROUND: Patients with multiple sclerosis (MS) are at increased risk of infection. Vaccination can mitigate these risks but only if safe and effective in MS patients, including those taking disease-modifying drugs. METHODS: A modified Delphi consensus process (October 2017-June 2018) was used to develop clinically relevant recommendations for making decisions about vaccinations in patients with MS. A series of statements and recommendations regarding the efficacy, safety and timing of vaccine administration in patients with MS were generated in April 2018 by a panel of experts based on a review of the published literature performed in October 2017. RESULTS: Recommendations include the need for an 'infectious diseases card' of each patient's infectious and immunisation history at diagnosis in order to exclude and eventually treat latent infections. We suggest the implementation of the locally recommended vaccinations, if possible at MS diagnosis, otherwise with vaccination timing tailored to the planned/current MS treatment, and yearly administration of the seasonal influenza vaccine regardless of the treatment received. CONCLUSION: Patients with MS should be vaccinated with careful consideration of risks and benefits. However, there is an urgent need for more research into vaccinations in patients with MS to guide evidence-based decision making.

RESUMO

STUDY OBJECTIVE: To investigate the clinical appearance and morphologic and ultrastructural aspects of the mucosa of the peritoneal neovagina after laparoscopic Davydov neovaginoplasty in patients with Mayer-Rokitansky-Küster-Hauser syndrome. DESIGN: The study group was a prospective, observational, experimental cohort of cases treated in the same institution between 2015 and 2019. Patients were followed up at 3, 6, and 12 months after surgery and then every 12 months. SETTING: Single-center academic institution and teaching hospital in Milan, Italy. PATIENTS: Fifty-one consecutive subjects with clinical and imaging diagnosis of Mayer-Rokitansky-Küster-Hauser syndrome surgically treated by the same team and postoperatively followed. INTERVENTIONS: All the subjects underwent the same standardized surgical procedure and thereafter were followed up at 3, 6, and 12 months after surgery and then every 12 months; a minimum follow-up of 12 months was achieved in all cases. Vaginoscopy and Schiller test were performed at each follow-up visit, and a biopsy specimen of the neovagina was obtained in a limited number of patients (6 out of 51) for light microscopy (LM) and scanning electron microscopy (SEM) analysis of the tissue. MEASUREMENTS AND MAIN RESULTS: In vaginoscopy, the neovaginal mucosa appeared homogeneous, smooth, and pink all along the neovaginal tract; the Schiller test detected iodine positivity at different degrees of extension upward from the hymenal ring, starting at 3 months postoperatively with almost complete positivity between 6 to 12 months in all cases. LM demonstrated adequate thickness and differentiation of the new mucosa along with the presence of glycogen storage; SEM revealed an ultrastructural surface appearance very close to normality. The main difference compared with a normal vagina was the reduced presence of vaginal mucosal folds. CONCLUSION: Under different techniques (vaginoscopy, Schiller test, LM, and SEM), a minimum of 6 months after surgery, the peritoneal neovagina epithelium showed aspects comparable to the natal mucosa of the vagina.

RESUMO

Vaginal atrophy occurring during menopause is closely related to the dramatic decrease in ovarian estrogens due to the loss of follicular activity. Particularly, significant changes occur in the structure of the vaginal mucosa, with consequent impairment of many physiological functions. In this study, carried out on bioptic vaginal mucosa samples from postmenopausal, nonestrogenized women, we present microscopic and ultrastructural modifications of vaginal mucosa following fractional carbon dioxide (CO2) laser treatment. We observed the restoration of the vaginal thick squamous stratified epithelium with a significant storage of glycogen in the epithelial cells and a high degree of glycogen-rich shedding cells at the epithelial surface. Moreover, in the connective tissue constituting the lamina propria, active fibroblasts synthesized new components of the extracellular matrix including collagen and ground substance (extrafibrillar matrix) molecules. Differently from atrophic mucosa, newly-formed papillae of connective tissue indented in the epithelium and typical blood capillaries penetrating inside the papillae, were also observed. Our morphological findings support the effectiveness of fractional CO2 laser application for the restoration of vaginal mucosa structure and related physiological trophism. These findings clearly coupled with striking clinical relief from symptoms suffered by the patients before treatment.

RESUMO

OBJECTIVE: The present study aimed to assess long-term follow-up outcomes in women with in situ/microinvasive adenocarcinoma (AC) of the uterine cervix treated conservatively. METHODS: Retrospective multi-institutional study including women with early glandular lesions and 5-year follow-up undergoing fertility-sparing treatment. Independent variables associated with recurrence were evaluated. Logistic regression analysis and Kaplan-Meier survival analysis with Logrank test were performed. RESULTS: Of 269 women diagnosed with in situ/microinvasive AC, 127 participants underwent conservative treatment. During follow-up, recurrences were found in nine women (7.1%). The only factor associated with recurrence during follow-up was positive high-risk Human Papillomavirus (hr-HPV) testing (odds ratio 6.21, confidence interval 1.47-26.08, p = 0.012). HPV positivity in follow-up showed a recurrence rate of 21.7% against 3.8% in patients who were HPV-negative (p = 0.002, Logrank test). Among women with negative high-risk HPV tests in follow-up, recurrences occurred in 20.0% of non-usual-type histology vs. 2.1% of usual-type cases (p = 0.005). CONCLUSION: HPV testing in follow-up is of pivotal importance in women with early glandular lesions undergoing conservative treatment, given its recurrence predictive value. However, women who are high-risk HPV-negative in follow-up with non-usual-type histopathology may represent a sub-population at increased risk of recurrences. Further studies should confirm these findings.

RESUMO

The World Health Organization (WHO) set the goal of 90% HPV vaccination coverage in the population to eliminate cervical cancer. Opportunistic vaccination is performed outside the free vaccination or catch-up programs. Both free and opportunistic HPV vaccination programs experienced slowdowns during the COVID-19 pandemic. In this retrospective study, we aimed to identify the benefits and the obstacles of opportunistic vaccination among male and female individuals who took advantage of the "on-demand" service offered by San Raffaele Hospital in Milan from April 2018 to May 2023. The impact that the COVID-19 pandemic had on vaccination adherence was also analyzed. Data on a total of 527 subjects were collected from an in-house database and through personal interviews. Women in the cohort of older patients (over 25) adhered to the vaccination schedule more than younger women. Opportunistic vaccination request is influenced by the need of a gynecologist, a general practitioner, or public health clinic availability. Women also showed good adherence to screening, demonstrating awareness of the importance of cervical cancer secondary prevention despite vaccination. Opportunistic vaccination offers the possibility of including individuals excluded from the free vaccination campaigns, often already affected by lesions caused by HPV, providing increased viral clearance and faster lesion regression. The main limit remains the economic burden.

RESUMO

INTRODUCTION: Botulinum toxin (BoNT) administration has been proposed in the gynecologic field for pelvic, vulvar and vaginal disorders. On this regard, we aimed assessing the therapeutic effectiveness and safety of BoNT usage in the treatment of vaginal, vulvar and pelvic pain disorders. METHODS: We searched for all the original articles without date restriction until 31.12.2021. We included all the original articles which administered botulinum toxin in the vulva or vagina of women suffering from vaginismus, dyspareunia, and chronic pelvic pain. Only English language studies and those performed in humans were eligible. We excluded all case reports and pilot study from the qualitative analysis, although we accurately evaluated them. 22 original studies were finally included in the systematic review. RESULTS: Botulinum toxin injection was found to be effective in improving vulvar and vaginal dyspareunia, vaginismus, and chronic pelvic pain. No irreversible side effects were detected. Major side effects reported were transient urinary or fecal incontinence, constipation and rectal pain. The risk of bias assessment proved original articles to be of medium quality. No metanalysis could have been performed since lack of congruency in the definition of pathology and methods of botulinum toxin administration. CONCLUSION: Data extraction pointed out different endpoints and different methods of analysis. Studies focus on different types of participants and use various techniques and timing. According to the best evidence available, different techniques provide evidence about positive outcomes, with the need for a standardized protocol.

RESUMO

Quality Control (QC) and Quality Assurance (QA) principles are essential for effective cervical cancer prevention. Being a crucial diagnostic step, colposcopy's sensitivity and specificity improvements are strongly advocated worldwide since inter- and intra-observer differences are the main limiting factors. The objective of the present study was the evaluation of colposcopy accuracy through the results of a QC/QA assessment from a survey in Italian tertiary-level academic and teaching hospitals. A web-based, user-friendly platform based on 100 colposcopic digital images was forwarded to colposcopists with different levels of experience. Seventy-three participants were asked to identify colposcopic patterns, provide personal impressions, and indicate the correct clinical practice. The data were correlated with a panel of experts' evaluation and with the clinical/pathological data of the cases. Overall sensitivity and specificity with the threshold of CIN2+ accounted for 73.7% and 87.7%, respectively, with minor differences between senior and junior candidates. Identification and interpretation of colposcopic patterns showed full agreement with the experts' panel, ranging from 50% to 82%, in some instances with better results from junior colposcopists. Colposcopic impressions correlated with a 20% underestimation of CIN2+ lesions, with no differences linked to level of experience. Our results demonstrate the good diagnostic performance of colposcopy and the need for improving accuracy through QC assessments and adhesion to standard requirements and recommendations.

RESUMO

OBJECTIVE: To evaluate the impact of healthcare reorganization during the severe acute respiratory syndrome coronavirus 2 pandemic on Italian colposcopy clinic activities, focusing on cervical excision procedures, follow-ups for conservative management of low-grade lesions, and follow-ups post cervical excision. METHODS: Retrospective study conducted in 14 Italian colposcopy clinics. The number and clinical characteristics of cervical excisions, follow-ups for conservative management of low-grade lesions, and follow-ups after cervical excision were compared between the period March 1, 2019 to February 29, 2020 (pre-pandemic) and March 1, 2020 to February 28, 2021 (pandemic) with a Poisson regression analysis. RESULTS: In the pandemic period, the number of cervical excisions was reduced by 8.8% (95% confidence interval [CI]=-15.6% to -2%; p=0.011). Excisions were less frequently performed in the operating room (-35.1%; 95% CI=-47.6% to -22.6%; p<0.001), the number of patients from spontaneous screening was reduced by -14.0% (95% CI=-23.4% to -4.6%; p=0.003), and the CO2-laser technique was used less frequently (-30%; 95% CI=-45.1% to -15.0%; p<0.001). As compared to the pre-pandemic period, the number of follow-ups for conservative management of low-grade lesions was reduced by -26.7% (95% CI=-39.0% to -14.4%; p<0.001), and the follow-up appointments after cervical excision were reduced by -51.0% (95% CI=-58.1% to -43.9%; p<0.001). CONCLUSION: The most significant impact of the healthcare reorganization during the coronavirus disease 2019 pandemic was on follow-ups after cervical excision. The resumption of disrupted activities should follow a risk-based prioritization, starting from women in follow-up after cervical excision. It is advisable that the trend of performing cervical excision as an outpatient procedure is maintained in the post-pandemic period.

RESUMO

It is unknown whether human papillomavirus (HPV) status impacts the prognosis of early stage cervical glandular lesions. This study assessed the recurrence and survival rates of in situ/microinvasive adenocarcinomas (AC) according to HPV status during a 5-year follow-up. The data were retrospectively analyzed in women with available HPV testing before treatment. One hundred and forty-eight consecutive women were analyzed. The number of HPV-negative cases was 24 (16.2%). The survival rate was 100% in all participants. The recurrence rate was 7.4% (11 cases, including four invasive lesions (2.7%)). Cox proportional hazards regression showed no difference in recurrence rate between HPV-positive and HPV-negative cases (p = 0.148). HPV genotyping, available for 76 women and including 9/11 recurrences, showed a higher relapse rate for HPV-18 than HPV-45 and HPV-16 (28.5%, 16.6%, and 9.52%, p = 0.046). In addition, 60% and 75% of in situ and invasive recurrences, respectively, were HPV-18 related. The present study showed that most ACs were positive for high-risk HPV, and the recurrence rate was unaffected by HPV status. More extensive studies could help evaluate whether HPV genotyping may be considered for recurrence risk stratification in HPV-positive cases.

RESUMO

AIM: To report the debate on the relationship between overactive bladder (OAB) in children and adults during the ICI-RS meeting in 2010. METHODS: Literature supporting or being against the theory that OAB in children and adults represents the same condition has been reviewed and debated. RESULTS: Growing evidence is showing a strong link between urinary symptoms in childhood, such as nocturnal enuresis (NE) and OAB symptoms, and OAB in adulthood. Behavioral and environmental factors may have an important role in predisposed subjects. Studies on familial and genetic factors have been reported. CONCLUSION: It might be inappropriate to state that OAB in children and adults represents the same condition. However, epidemiological and genetic findings demonstrate a strong link between OAB symptoms in these two different ages of life. Predisposing factors and behavioral and/or environmental elements may lead to OAB occurrence in adults.

RESUMO

Objective: The objective of the present study was to investigate the potential prognostic role of neutrophil-lymphocyte ratio (NLR) in comparison with known parameters of prediction for the detection of recurrences of cervical intraepithelial neoplasia (CIN) after treatment. Methods: We retrospectively evaluated patients who underwent surgical treatment for CIN2, CIN3, and carcinoma in situ (CIN2+) between 2010 and 2019. NLR was recorded before surgery, and the follow-up records of patients were analyzed. Cases were splitted into two subgroups according to baseline NLR-low-NLR for <2 and high-NLR for ≥2 values of the index-and correlated with recurrences. Results: 428 cases fulfilled the criteria and were included in the study. Recurrence rate in patients with NLR <2.0 and NLR ≥2.0 was 15.2% and 27.3%, respectively, being the odd ratio for recurrence significantly higher in patients with NLR ≥2 (OR = 2.09; 95% CI 1.28-3.41; p = 0.003). A highly significant statistical difference in recurrence rate was demonstrated, in both univariate and multivariate, for surgical margins, follow-up HPV-DNA status, and NLR values. Conclusion: Preoperative NLR categorization is a strong independent prognostic factor for recurrences after surgical excision of CIN. NLR evaluation is a simple, reproducible, and cost-effective clinical instrument that could optimally be introduced in clinical practice in every setting.

RESUMO

OBJECTIVE: To analyze the clinical management, the outcomes, and the trend in hysterectomy rates (HR) in patients who underwent this procedure for cervical intraepithelial neoplasia (CIN). METHODS: Multicentric retrospective observational study conducted on 242 patients who underwent hysterectomy for CIN between 2010 and 2020 in nine Italian institutions. Hysterectomy for invasive or micro-invasive neoplasia, sub-total hysterectomy, or trachelectomy were excluded. RESULTS: A significant increase in the trend of HR for CIN was recorded (P = 0.002, r = 0.81; C.I. 95%: 0.415-0.949); HR increased from 0.46% in the year 2010 to 3.32% in 2020. The mortality rate was 0.4%, and 5% had operative complications. On definitive histopathology examination, a CIN of any grade was recorded in 71.5% of cases, and an occult invasive cancer in 1.24%. No pathology or CIN1 was found in 26.8% of cases, suggesting over treatment. During follow-up, a vaginal lesion was recorded in 5% of cases. CONCLUSION: A significant increase in the number of hysterectomies performed for CIN in the last 10 years was recorded. Hysterectomy for CIN can lead to complications, risk of the onset of vaginal lesions, and risk of overtreatment, and remains, in the first instance, an unacceptable treatment, to be proposed only after adequate counseling.

RESUMO

Primary cervical melanocytic schwannomas, arising from the sympathetic chain, are very rare pigmented neural sheath tumors that, both grossly and clinically, are often misdiagnosed with other more frequent lesions of the uterine cervix. Literature review accounts for seventeen published cases of schwannomas of the cervix, ten of which are malignant and seven benign. Pathological examination with immunostaining techniques is essential for the correct diagnosis of these tumors. We report a case of primary cervical schwannoma in a 32-year-old female who was referred to our department at 13 weeks of gestation with a diagnosis of malignant melanoma of the cervix. Pathological review detailed a neoplasm with a myxoid spindle cell component and a minority of small epithelioid cells, with a low-malignant potential proliferation index: morphological and immunocytochemical findings were compatible with the diagnosis of nerve sheath tumor, type schwannoma. The patient underwent a vaginal trachelectomy and a prophylactic Shirodkar's cerclage. Pregnancy was carried on without any negative event. The patient delivered by a caesarean section a healthy female newborn. Placental histology was negative. After 6 years from the first diagnosis, the patient is healthy and disease free.

RESUMO

BACKGROUND: Efficacy of the nine-valent human papillomavirus (9vHPV; HPV types 6/11/16/18/31/33/45/52/58) vaccine was demonstrated in a phase 3 study in women 16-26 years of age. We present a phase 3 immunogenicity and safety study of the 9vHPV vaccine in women 27-45 versus 16-26 years of age. METHODS: This international, open-label study (NCT03158220) was conducted in women 16-45 years of age. Participants (16-26 years, n = 570 and 27-45 years, n = 642) received a three-dose 9vHPV vaccination regimen (day 1, month 2, month 6). Month 7 geometric mean titers (GMTs) and seroconversion percentages to anti-HPV 6/11/16/18/31/33/45/52/58 were assessed. Participants were followed for safety throughout the study. RESULTS: At month 7, anti-HPV 6/11/16/18/31/33/45/52/58 GMTs in women 27-45 years were compared to those in women 16-26 years of age. The primary hypothesis of non-inferiority of anti-HPV 16/18/31/33/45/52/58 GMTs in older versus younger women was met. The lower bound of the GMT ratio 95% confidence interval (27-45 years to 16-26 years) was 0.60-0.67 depending on HPV type, exceeding the non-inferiority margin of 0.5 for all HPV types. Month 7 seroconversion percentages in women 27-45 years of age were >99% for all HPV types. Injection-site and vaccine-related systemic adverse events (AEs) were observed in 87.5% and 25.1% of women 16-26 years, and 85.2% and 24.1% of women 27-45 years of age, respectively; no vaccine-related serious AEs were reported and no deaths occurred during the study. CONCLUSIONS: The 9vHPV vaccine elicited non-inferior anti-HPV GMTs in women 27-45 years compared with women 16-26 years of age for HPV 16/18/31/33/45/52/58. The vaccine was generally well tolerated with a similar AE profile across the age groups. These data support bridging 9vHPV vaccine efficacy findings in women 16-26 years to women 27-45 years of age. Clinical trial registration NCT03158220.

RESUMO

Cervical neoplastic lesions are associated with infection by high-risk human papilloma-viruses (HPV). The two genotypes most frequently found in the lesions are HPV-16 and HPV-18 with a prevalence of 50-60% and 15-18%, respectively. The E6 and E7 viral oncoproteins are involved in the transformation process and represent foreign antigens for the host. We previously reported that anti-HPV-18 E6 CD4(+) T cells are present in patients with high-grade HPV-18-expressing cervical lesions but also in 50% of the total consecutive patients tested, independently of the HPV type carried. These results indicated that HPV-18 E6 is immunogenic and suggested that all responsive patients, irrespective of the HPV expressed, had encountered HPV-18 and cleared the infection. Here, we investigated anti-HPV-18 E7 CD4(+) T-cell immunity in a cohort of 23 HPV-18 E6-responsive patients. We found that, although E7-specific CD4(+) T cells were present in all women, a robust T helper type (Th1)/Th2 type response against E7 was associated with HPV-18-negative status, suggesting that indeed these patients might have cleared the virus. In agreement with this hypothesis, we found strong anti-E7 CD4(+) T-cell immunity in 20% of 24 healthy donors without evidence of disease. In contrast, a robust Th1/Th2 type response against E6 but not E7 correlated with a lack of disease relapse and/or infection recurrence but did not discriminate between HPV-18-positive and HPV-18-negative patients. Collectively, our data suggest different roles for anti-HPV-18 E6 and E7 CD4(+) T cells in anti-viral and anti-tumour immunity.

RESUMO

HPV vaccination has been introduced in clinical practice in recent years and represents the most effective strategy of primary prevention of cervical carcinoma and of female genital preneoplastic conditions. One of the major issues of the subject is represented by vaccination coverage of the target population. Since its introduction, HPV vaccine efficacy has been progressively demonstrated also towards extragenital HPV-correlated conditions and in males too. Moreover, even subjects of older age groups or subjects who already had HPV infections have been demonstrated to received benefits from vaccination, due to improvements of their immunological response. Recently, vaccine efficacy has also been investigated in terms of adjuvant administration after treatments of preneoplastic or benign conditions of the female lower genital tract caused by HPVs; preliminary results indicate an interesting and promising field of application. On this basis, in this article an analysis of the state of the art has been performed, with specific regard to the Italian scenario and with the focus of future perspectives of implementation of the HPV vaccination policy. From the available evidences, the Italian HPV Study Group recommends the extension of systematic HPV vaccination to males too, to adult subjects and also after conservative treatment of genital HPV correlated conditions.

RESUMO

OBJECTIVE: Because the interaction between viral DNA products and cellular regulatory mechanisms is the first step leading to cancerous transformation, the detection of its presence in histologically negative lymph nodes may represent a very early biological step in cancer spread. The quantitative estimate may represent and an indirect sign of active cellular replication. MATERIALS AND METHODS: Cervical and lymph nodes tissues of 13 cases of invasive cervical cancer were analyzed for human papillomavirus (HPV)-DNA presence and viral load by HPV typing and quantification by real-time polymerase chain reaction. RESULTS: HPV-DNA was demonstrated in all tissue samples (primary tumor, positive lymph nodes, negative lymph nodes) with the most prevalence of HPV 16 (61.5%) and single-type infection (69.3%), whereas viral load (mean quantity of DNA copies) is statistically different in negative versus positive lymph nodes (p =.005). CONCLUSIONS: Concordance of viral type and lymph nodes viral load may represent as a useful tool in identifying early metastatic risk of tumor spread.
