Efficacy of Listening to Music on Pain Reduction during Colposcopy-Directed Cervical Biopsy: A Randomized, Controlled Trial.

Background and Objective: To investigate the efficacy of listening to music on pain reduction during colposcopy-directed cervical biopsy (CDB). Materials and Methods: From June 2020 to November 2021, 240 women undergoing CDB were enrolled. The participants were randomized into three groups: Group 1, colposcopic examination while wearing headphones and listening to music; Group 2, colposcopy while wearing headphones but not listening to music; Group 3 (control group), colposcopy while neither listening to music nor wearing headphones. All participating women completed a 10 cm visual analog scale for subjective pain at three time points: baseline, immediately after cervical biopsy, and 15 min after the procedure. The primary endpoint was the biopsy pain score. Result: Of the 240 women, a sample size of 80 was randomly assigned per group. The clinical-pathological and procedure-related characteristics of the participants in all groups were similar. The mean baseline pain score between each group was not significantly different (2.83 in the music group, 2.54 in group 2, and 2.94 in the control group, p = 0.47). There were no significant differences between each group in terms of mean biopsy pain score (4.21 in the music group, 4.24 in group 2, and 4.30 in the control group, p = 0.98). The differences in changes between the baseline pain score and the biopsy pain score were not statistically significant (1.39 in the music group, 1.70 in group 2, and 1.36 in the control group, p = 0.69). In the multiple comparison analysis, the differences in changes between the biopsy pain score and the baseline pain score between each group were also not statistically significant. There were no complications with the intervention observed. Conclusion: This study demonstrated that there was no beneficial effect of listening to music on pain reduction during colposcopy-directed cervical biopsies.

Evidence to Support Change of Clinical Pathway Following Colposcopy Treatment for Cervical Intraepithelial Neoplasia in Canada.

OBJECTIVES: Human papillomavirus (HPV) testing can be incorporated into the post-treatment pathway of cervical intraepithelial neoplasia (CIN) to confirm disease-free status. To inform a post-treatment strategy based on risk of recurrence, we modelled disease and economic outcomes. METHODS: The current Alberta, Canada, post-treatment care pathway-cytology testing with colposcopy assessment-was compared with 6 other scenarios incorporating cytology, HPV testing, or both tests at different time points in a modelling study based on a microsimulation program. Input parameter values for the screening participation, screening age groups, and follow-up options and test compliance for HPV, cytology, and colposcopy were varied, based on Alberta cervical cancer screening program data. Health outcomes over the short- and long-term were projected, which incorporated the increasing population-level coverage of HPV vaccination. Lifetime incremental cost-effectiveness ratios (ICERs) were used to evaluate economic outcomes and descriptive statistics compared with numbers of tests, visits, and procedures as well as changes in incidence and mortality rates between the scenarios. RESULTS: At 5 years after implementation of the "HPV testing alone at 6 and 18 months" post-treatment pathway, the number of colposcopies dropped by 36% and the number of pre-cancer treatments, by 6%. Lifetime ICERs were CAD $6170 versus $248,495 per quality-adjusted life-year compared with the status quo pathway. Cervical cancer incidence and mortality rates decreased significantly and similarly in all scenarios. CONCLUSION: Strategies that involve HPV testing in CIN post-treatment follow-up care are expected to be more cost effective with improved clinical outcomes than traditional cytology and colposcopy-based follow-up.

Mechanical dilatation of the stenosed cervix under local anesthesia: A prospective case series.

AIM: Cervical stenosis is traditionally managed by mechanical dilatation under general anesthesia (GA). We aimed to assess the safety, effectiveness, and patient acceptability of dilatation in the outpatient setting under local anesthesia (LA). METHODS: Data were collected prospectively from all patients attending the outpatient department with cervical stenosis from March 20, 2015 to September 23, 2020. Mechanical dilatation of the cervix was performed using Hegar dilators under LA. Subsequent colposcopic assessment, cytology, histology, and management were recorded. RESULTS: One hundred forty-nine cases were referred for cervical dilatation, 63 (43%) of which had complete stenosis. One hundred eighteen (79%) patients had previously undergone cervical procedures. Successful dilatation under LA was achieved in 119 (83%) patients; 5 (3%) declined (requesting GA), 6 (4%) did not tolerate speculum examination, and 19 (13%) had unsuccessful procedures. The median Hegar size used was 8 mm. Dilatation under LA was acceptable in 93% attempted procedures. Thirteen episodes of restenosis were recorded with no major adverse events. Younger age (p = 0.045) and severe (compared to complete) stenosis (p < 0.0001) were associated with procedure success, with improved results over time (p = 0.003). Successful dilatation permitted cervical assessment; eight patients required cervical excisions, two underwent hysterectomies, with one confirmed case of adenocarcinoma. CONCLUSION: Rigid cervical dilatation in the outpatient setting provides effective, instantaneous treatment for women who have failed cytological or colposcopic assessment. For the vast majority of women, the procedure was well tolerated and preferred to using GA. However, given that 1 in 10 women experienced restenosis, patients should be counseled about the possibility of requiring further management.

Risk of cervical precancer and cancer among uninsured and underserved women from 2009 to 2017.

BACKGROUND: New guidelines for managing cervical precancer among women in the United States use risk directly to guide clinical actions for individuals who are being screened. These risk-based management guidelines have previously only been based on risks from a large integrated healthcare system. We present here data representative of women of low income without continuous insurance coverage to inform the 2019 guidelines and ensure applicability. OBJECTIVE: We examined the risks of high-grade precancer after human papillomavirus and cytology tests in underserved women and assessed the applicability of the 2019 guidelines to this population. STUDY DESIGN: We examined cervical cancer screening and follow-up data among 363,546 women enrolled in the Centers for Disease Control and Prevention's National Breast and Cervical Cancer Early Detection Program from 2009 to 2017. We estimated the immediate (prevalent) risks of cervical intraepithelial lesion grade 3 or cancer by using prevalence-incidence mixture models. Risks were estimated for each combination of human papillomavirus and cytology result and were stratified by screening history. We compared these risks with published estimates used in new risk-based management guidelines. RESULTS: Women who were up-to-date with their screening, defined as being screened with cytology within the past 5 years, had immediate risks of cervical intraepithelial neoplasia grade 3 or higher similar to that of women at Kaiser Permanente Northern California, whose data were used to develop the management guidelines. However, women in the Centers for Disease Control and Prevention's National Breast and Cervical Cancer Early Detection Program had greater immediate risks if they were never screened or not up-to-date with their screening. CONCLUSION: New cervical risk-based management guidelines are applicable for underinsured and uninsured women with a low income in the United States who are up-to-date with their screening. The increased risk observed here among women who received human papillomavirus-positive, high-grade cytology results, who were never screened, or who were not up-to-date with their cervical cancer screening, led to a recommendation in the management guidelines for immediate treatment among these women.

Syringe or mask? Loop electrosurgical excision procedure under local or general anesthesia: a randomized trial.

BACKGROUND: Loop electrosurgical excision procedure may be performed under local anesthesia or general anesthesia, and practice patterns differ worldwide. No randomized head-to-head comparison has been published to confirm or refute either practice. OBJECTIVE: This study aimed to compare loop electrosurgical excision procedure under local anesthesia vs general anesthesia regarding patient satisfaction and procedure-related outcomes such as rates of involved margins, complications, pain, and blood loss. STUDY DESIGN: Consecutive women referred to our colposcopy unit were recruited. Loop electrosurgical excision procedure was performed under local anesthesia with 4 intracervical injections of bupivacaine hydrochloride 0.5% or under general anesthesia with fentanyl, propofol, and a laryngeal mask with sevoflurane maintenance. The primary endpoint was patient satisfaction assessed on the day of surgery and 14 days thereafter using a Likert scale (score 0-100) and a questionnaire. Secondary endpoints included rates of involved margins, procedure-related complications, pain, blood loss, and surgeon preference. Results were compared using nonparametric and chi-square tests. RESULTS: Between July 2018 and February 2020, we randomized 208 women, 108 in the local anesthesia arm and 100 in the general anesthesia arm. In the intention-to-treat analysis, patient satisfaction did not differ between the study groups directly after surgery (Likert scale 100 [90-100] vs 100 [90-100]; P=.077) and 14 days thereafter (Likert scale 100 [80-100] vs 100 [90-100]; P=.079). In the per-protocol analysis, women in the local anesthesia arm had significantly smaller cone volumes (1.11 cm3 [0.70-1.83] vs 1.58 cm3 [1.08-2.69], respectively; P<.001), less intraoperative blood loss (Δhemoglobin, 0.2 g/dL [-0.1 to 0.4] vs 0.5 g/dL [0.2-0.9]; P<.001), and higher satisfaction after 14 days (100 [90-100] vs 100 [80-100]; P=.026), whereas surgeon preference favored general anesthesia (90 [79-100] vs 100 [90-100], respectively; P=.001). All other secondary outcomes did not differ between groups (resection margin status R1, 6.6% vs 2.1% [P=.26]; cone fragmentation, 12.1% vs 6.3% [P=.27]; procedure duration, 151.5 seconds [120-219.5] vs 180 seconds [117-241.5] [P=.34]; time to complete hemostasis, 60 seconds [34-97] vs 70 seconds [48.25-122.25] [P=.08]; complication rate, 3.3% vs 1.1% [P=.59]). In a multivariate analysis, parity (P=.03), type of transformation zone (P=.03), and cone volume (P=.02) and not study group assignment, age, body mass index, and degree of dysplasia independently influenced the primary endpoint. CONCLUSION: Loop electrosurgical excision procedure under local anesthesia is equally well tolerated and offers patient-reported and procedure-related benefits over general anesthesia, supporting the preferred practice in some institutions and refuting the preferred practice in others.

An Alternative Treatment for Vaginal Cuff Wart: a Case Report.

Human papillomavirus (HPV) has been directly related to acuminate warts and cervical cancer, the second most common neoplasia among women. Given the lack of treatment against the virus itself, many medications have been utilised, mainly aiming in modifying the host's immunological response. We present the case of a 54 years old postmenopausal patient with a history of vaginal cuff wart and HPV persistence that we managed in our clinic for 6 months with a mix of curcumin, aloe vera, amla and other natural ingredients. As the patient was found to be intolerant to imiquimod (one of the most common conservative methods of treatment) we attempted the use of curcumin, which was applied to the area of the wart three times per week for 6 months. Both clinical and colposcopical improvement was noted in regular clinic visits with regression of the lesion. The outcome of this case encourages our view that curcumin should be considered as a significant treatment modality against HPV infection and acuminate warts.

Implementation of HPV-based Cervical Cancer Screening Combined with Self-sampling Using a Midwifery Network Across Rural Greece: The GRECOSELF Study.

Self-sampling for human papillomavirus (HPV) testing is an alternative to physician sampling particularly for cervical cancer screening nonattenders. The GRECOSELF study is a nationwide observational cross-sectional study aiming to suggest a way to implement HPV-DNA testing in conjunction with self-sampling for cervical cancer screening in Greece, utilizing a midwifery network. Women residing in remote areas of Greece were approached by midwives, of a nationwide network, and were provided with a self-collection kit (dry swab) for cervicovaginal sampling and asked to answer a questionnaire about their cervical cancer screening history. Each sample was tested for high-risk (hr) HPV with the Cobas HPV test. HrHPV-Positive women were referred to undergo colposcopy and, if needed, treatment according to colposcopy/biopsy results. Between May 2016 and November 2018, 13,111 women were recruited. Of these, 12,787 women gave valid answers in the study questionnaire and had valid HPV-DNA results; hrHPV prevalence was 8.3%; high-grade cervical/vaginal disease or cancer prevalence was 0.6%. HrHPV positivity rate decreased with age from 20.7% for women aged 25-29 years to 5.1% for women aged 50-60 years. Positive predictive value for hrHPV testing and for HPV16/18 genotyping ranged from 5.0% to 11.6% and from 11.8% to 27.0%, respectively, in different age groups. Compliance to colposcopy referral rate ranged from 68.6% (for women 25-29) to 76.3% (for women 40-49). For women residing in remote areas of Greece, the detection of hrHPV DNA with the Cobas HPV test, on self-collected cervicovaginal samples using dry cotton swabs, which are provided by visiting midwives, is a promising method for cervical cancer secondary prevention.

[Parameters for programming line of care procedures for cervical cancer in Brazil]. / Parâmetros para a programação de procedimentos da linha de cuidado do câncer do colo do útero no Brasil.

The study estimated parameters for planning and programming the supply of procedures for screening, diagnostic workup, and treatment of precursor lesions of uterine cervical cancer. These estimates were used as the basis for assessing the adequacy of Brazil's production of procedures performed by the Brazilian Unified National Health System (SUS) in 2017. Estimates were calculated using as the reference the recommended management in the national screening guidelines. Data on screening tests were obtained from the Information System on Uterine Cervical Cancer and the follow-up data from patient charts in a referral center for cervical pathology. Brazil's production of procedures was obtained from data in the Outpatient and Hospital Information Systems of the SUS. For every one hundred thousand women in the target age bracket for screening (25 to 64 years) there was an estimated annual need for 44,134 cytopathology tests, 1,886 colposcopies, 275 biopsies, 236 type 1 and 2 outpatient exicision procedures, 236 type 2 and 3 hospital exicision procedures, and 39 high-complexity referrals for surgery, chemotherapy, and/or radiotherapy. Applying the estimated parameters to the number of women screened in Brazil in 2017, a deficit was identified in all the procedures for adequate follow-up of the women with altered test results, varying from 7% in colposcopies to 74% in type 3 excisions. The results point to the need to expand and upgrade the supply of line of care procedures for cervical cancer. The estimated parameters can support policymakers in programming and implementing organized screening programs.

Effect of music in reducing patient anxiety during colposcopy: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Music therapy has been used greatly in various medical procedures to reduce associated anxiety and pain. OBJECTIVE: to evaluate the evidence from published randomized clinical trials (RCTs) about the effect of music intervention in reducing patient's anxiety during the colposcopy. SEARCH STRATEGY: Electronic databases included PubMed, Cochrane Library, Scopus and Web of Science were searched using the relevant MeSH terms. SELECTION CRITERIA: All RCTs assessing the effect of music therapy versus no music in reducing anxiety during colposcopy were considered. Eighty-five studies were identified of which five studies deemed eligible for this review. DATA EXTRACTION: The extracted outcomes were; anxiety, pain during and after the procedure, and satisfaction levels. They were pooled as mean difference in a fixed-effects model, using Review Manager 5.3 software for windows. MAIN RESULTS: We found no effect of music therapy in reducing the anxiety levels when compared with the control group (SMD= -0.11, 95% CI [-0.36, 0.14], p=0.4). No difference between music and control groups regarding pain during and after the procedure respectively (SMD= -0.20, 95% CI [-0.58, -0.18], p=0.31) and (SMD=-0.10, 95% CI [-0.30, -0.10], p=0.33). CONCLUSIONS: Music therapy had no positive effect in reducing anxiety, pain and satisfaction levels during colposcopy.

Effect of Immunomodulatory Supplements Based on Echinacea Angustifolia and Echinacea Purpurea on the Posttreatment Relapse Incidence of Genital Condylomatosis: A Prospective Randomized Study.

Introduction. HPV infection is a highly infectious disease; about 65% of partners of individuals with genital warts will develop genital condylomatosis. Only in 20-30% it regresses spontaneously and relapse rates range deeply (9-80%). Echinacea extracts possess antiviral and immunomodulator activities. The aim of this study was to evaluate the efficacy of the therapy, using a formulation based on HPVADL18® (on dry extracts of 200 mg Echinacea Purpurea (EP) roots plus E. Angustifolia (EA)), on the posttreatment relapse incidence of genital condylomatosis. Materials and Methods. It is a prospective single-arm study. Patients with a satisfactory and positive vulvoscopy, colposcopy, or peniscopy for genital condylomatosis were divided into two random groups and subjected to destructive therapy with Co2 Laser. Group A (N=64) immediately after the laser therapy started a 4-month treatment with oral HPVADL18®; Group B (N=61) did not undergo any additional therapy. Patients were subjected to a follow-up after 1, 6, and 12 months. Differences in relapse incidence between the two groups during follow-up controls were evaluated by χ2-test; the groups were stratified by age, gender, and condylomatosis extension degree. Results and Discussion. Gender, age, and condyloma lesions' extension degree showed no statistically significant differences between the two trial groups. The relapse incidence differs statistically between the two studied groups and progressively decreases during the 12 months after treatment in both groups. Statistically significant reduction of relapse rates has been shown in Group A in patients over 25 years old. This difference is significant for both men and women. The relapse incidence is superior in case of extended condylomatosis. Conclusions. In conclusion, the presence of a latent infection causes condylomatosis relapse; in order to reduce the relapse risk an induction of a protective immune response seems to be essential to allow rapid viral clearance from genital areas surrounding lesion and treatment zones. Echinacea promotes this process. EP and EA dry root extracts seem to be a valid adjuvant therapy in reducing relapse incidence of lesions in patients treated for genital condylomatosis.

The Relationship between the Serum Level of Selenium and Cervical Intraepithelial Neoplasia: A Comparative Study in a Population of Nigerian Women

Objective: To determine the relationship between the serum level of selenium and cervical intraepithelial neoplasia (CIN). Methods: A case controlled study that compared the serum level of selenium in 45 women with CIN (cases) to 45 women (age matched controls) with normal cervical cytology. Socio-demographic data and information on known risk factors for cervical cancer among the sample was compared between both groups using inferential statistics. Results: There was no significant difference in the mean selenium values between the cases and controls [p- 0.076, 95% CI (-15.08 ­ 0.76)]. However, subgroup analysis showed a statistically significant difference between patients with normal cervical cytology, CIN I, II and III (p= 0.021). In addition, there was also significant difference in the selenium level between women with normal cervical cytology and CIN III (p value = 0.016) with a significant inverse linear trend (p= 0.025). Conclusion: With increasing severity of CIN, a significant reduction in the level of selenium in serum was observed. This reducing value of serum selenium, a surrogate marker for increased oxidative stress, may be important factor for the development of persistent HPV infection and in particular high grade CIN III lesions. This observation requires further research.

Adenocarcinoma cervical: diagnóstico na atenção primária e secundária à saúde / Cervical adenocarcinoma: diagnosis in primary and secondary health care

O adenocarcinoma cervical é uma patologia grave cuja incidência tem aumentado, principalmente em pacientes jovens. Um diagnóstico oportuno, na assistência primária e secundária à saúde, com métodos convencionais, melhora sobremaneira o prognóstico da paciente, a um custo tolerável para países em desenvolvimento.(AU)

The cervical adenocarcinoma is a serious pathology whose incident has increased mainly in young patients. One opportunistic diagnosis, in primary and secondary health care, with conventional methods, greatly improves the prognosis of the patients, at a cost tolerable to developing countries.(AU)

Management and treatment of cervical intraepithelial neoplasia in the Netherlands after referral for colposcopy.

INTRODUCTION: The aim of this study was to describe trends in the diagnosis and treatment of women referred from the national screening program with cervical intraepithelial neoplasia (CIN) in the Netherlands, and to compare these trends with national guidelines and identify potential areas for improvement for the new primary high-risk HPV screening program. MATERIAL AND METHODS: We conducted a population-based cohort study using data from the Dutch pathology archive. Women aged 29-63 years who took part in the Dutch cervical screening program between 1 January 2005 and 31 December 2014 were selected. Three referral groups were identified: direct referrals and those referred after either one (first indirect referrals) or two (second indirect referrals) repeat cytology tests, totaling 85 239 referrals for colposcopy. The most invasive management technique and the most severe diagnosis of each screening episode was identified. Rates of management techniques were calculated separately by referral type, highest CIN diagnosis and age group. RESULTS: In all, 85.1% of CIN 3 lesions were treated with excision (either large excision or hysterectomy) and 26.4% of CIN 1 lesions were treated with large excision. Rates of overtreatment (CIN 1 or less) in see-and-treat management were higher for indirect referrals than for direct referrals and increased with age. Large excision rates increased with CIN diagnosis severity. CONCLUSIONS: Despite guideline recommendations not to treat, CIN 1 lesions were treated in just over 25% of cases and approximately 15% of CIN 3 lesions were possibly undertreated. Given the expected increase in CIN detection in the new primary high-risk HPV screening program, reduction in CIN 1 treatment and CIN 2 treatment in younger women is needed to avoid an increase in potential harm.

Organized Cervical Cancer Screening Program in Barretos, Brazil: Experience in 18 Municipalities of São Paulo State.

OBJECTIVES: The aim of this report is to demonstrate the Barretos Cancer Hospital initiative of organizational, laboratorial, and human resources training in the implementation of an organized cervical screening program in low-resource settings. METHODS: We developed a computational program to report all epidemiological, clinical, and laboratorial findings, and to trace all necessary information to recruit women for regular screening or for referral for complementary exams after liquid-based Pap test analyses. RESULTS: All Pap tests were collected in liquid medium and in 2014 more than 160,000 tests were analyzed and 2,900 colposcopy examinations were performed. From 2012 to 2015, the percentage of exams collected increased from 54.6% in 2012 to 62.4% in 2013, 68.4% in 2014, and 71% in 2015. Per 1,000 Pap tests, 0.4 cases of invasive cancer were diagnosed; for in situ carcinoma, 1.9 cases were identified. More importantly, between 2011 and 2015, 89.4% of all carcinomas were detected at clinical stage 0 or I (in situ carcinoma), and only 5% at stages III and IV. CONCLUSIONS: Since the organized system was implemented, 98% of women have attended their recall for colposcopy.

Effect of Several Negative Rounds of Human Papillomavirus and Cytology Co-testing on Safety Against Cervical Cancer: An Observational Cohort Study.

Background: Current U.S. cervical cancer screening and management guidelines do not consider previous screening history, because data on multiple-round human papillomavirus (HPV) and cytology "co-testing" have been unavailable. Objective: To measure cervical cancer risk in routine practice after successive negative screening co-tests at 3-year intervals. Design: Observational cohort study. Setting: Integrated health care system (Kaiser Permanente Northern California, Oakland, California). Patients: 990 013 women who had 1 or more co-tests from 2003 to 2014. Measurements: 3- and 5-year cumulative detection of (risk for) cervical intraepithelial neoplasia grade 3, adenocarcinoma in situ, and cervical cancer (≥CIN3) in women with different numbers of negative co-tests, overall and within subgroups defined by previous co-test results or baseline age. Results: Five-year ≥CIN3 risks decreased after each successive negative co-test screening round (0.098%, 0.052%, and 0.035%). Five-year ≥CIN3 risks for an HPV-negative co-test, regardless of the cytology result, nearly matched the performance (reassurance) of a negative co-test for each successive round of screening (0.114%, 0.061%, and 0.041%). By comparison, ≥CIN3 risks for the cytology-negative co-test, regardless of the HPV result, also decreased with each successive round, but 3-year risks were as high as 5-year risks after an HPV-negative co-test (0.199%, 0.065%, and 0.043%). No interval cervical cancer cases were diagnosed after the second negative co-test. Independently, ≥CIN3 risks decreased with age. Length of previous screening interval did not influence future ≥CIN3 risks. Limitation: Interval-censored observational data. Conclusion: After 1 or more negative cervical co-tests (or HPV tests), longer screening intervals (every 5 years or more) might be feasible and safe.

Pain Sensation During Colposcopy and Cervical Biopsy, With or Without Local Anesthesia: A Randomized Trial.

OBJECTIVE: The aim of the study was to determine whether an injection of a local anesthetic is more painful than a cervical punch biopsy without local anesthesia. MATERIALS AND METHODS: The study was a randomized controlled trial, conducted at the Helsinki University Central Hospital. It consisted of 204 women referred for colposcopic assessments. Half of them were randomized to receive local anesthesia before their cervical punch biopsies. After the injection of the local anesthetic, the cervical punch biopsy, and the endocervical curettage, the women scored their actual pain using a 10-cm visual analog scale (VAS).To measure the difference in VAS scores between two groups, a linear regression model was used. Binomial regression model was applied for comparing the probability of experiencing unbearable pain between the groups. Applying modeling approach allowed also for proper adjustment for other potential risk factors. RESULTS: The mean VAS score for the injection of the local anesthetic was 2.7, the VAS score for the cervical punch biopsy without local anesthesia was 3.5, and the difference was 0.8 (p = .017; 95% CI = 0.1-1.5). The mean VAS for the biopsy with local anesthesia was 0.8, which was significantly lower than the mean VAS for the biopsy without local anesthesia (difference = 2.7; p < .001; 95% CI = 2.2-3.3). The relative risk for experiencing moderate or severe pain (VAS ≥ 5) was 0.6 (p = .03; 95% CI = 0.3-0.9) for the injection of local anesthetic versus the biopsy without local anesthesia. CONCLUSIONS: Injection of a local anesthetic for colposcopy is less painful than biopsies without local anesthesia, and local anesthesia decreases the pain perceived.

Effects of Long-Term Vitamin D Supplementation on Regression and Metabolic Status of Cervical Intraepithelial Neoplasia: a Randomized, Double-Blind, Placebo-Controlled Trial.

We are not aware of any study examining the effects of long term vitamin D administration on regression and metabolic status of patients with cervical intraepithelial neoplasia grade 1 (CIN1). This study was performed to evaluate the effects of long-term vitamin D administration on regression and metabolic status of patients with CIN1. This randomized, double-blind, placebo-controlled trial was performed among 58 women diagnosed with CIN1. CIN1 diagnosis was performed based on specific diagnostic procedures of biopsy, pathological diagnosis, and colposcopy. Patients were randomly allocated into two groups to take 50,000 IU vitamin D3 supplements (n = 29) or placebo (n = 29) every 2 weeks for 6 months. Fasting blood samples were taken at the beginning of the study and end-of-trial to measure related markers. After 6 months of vitamin D administration, greater percentage of women in the vitamin D group had regressed CIN1 (84.6 vs. 53.8%, P = 0.01) than those in the placebo group. Long-term vitamin D supplementation increased serum-25(OH) vitamin D levels in the intervention group compared to the placebo group (+12.3 ± 11.4 vs. -0.1 ± 3.7 ng/mL, P < 0.001). In addition, vitamin D intake led to significant decreases in serum insulin levels (-5.3 ± 7.3 vs. +2.4 ± 5.9 µIU/mL, P < 0.001), homeostasis model of assessment-insulin resistance (-1.2 ± 1.6 vs. +0.5 ± 1.2, P < 0.001), homeostatic model assessment-Beta cell function (P = 0.005) and a significant elevation in quantitative insulin sensitivity check index (+0.03 ± 0.04 vs. -0.007 ± 0.02, P < 0.001) compared with the placebo group. Additionally, significant increases in plasma nitric oxide (NO) (+15.5 ± 10.3 vs. +4.0 ± 13.4 µmol/L, P = 0.001), total antioxidant capacity (TAC) (P = 0.04), total glutathione (GSH) (+11.8 ± 153.5 vs. -294.2 ± 595.1 µmol/L, P = 0.01) and a significant reduction in plasma malondialdehyde (MDA) levels (-0.8 ± 1.0 vs. -0.03 ± 1.4 µmol/L, P = 0.03) were observed following the administration of vitamin D supplements compared with the placebo group. In conclusion, vitamin D3 administration for 6 months among women with CIN1 resulted in its regression and had beneficial effects on markers of insulin metabolism, plasma NO, TAC, GSH and MDA levels.
