Abstract
INTRODUCTION The morphology of high-grade squamous intraepithelial lesion (HSIL) on Papanicolaou (Pap) smears widely varied, including syncytial aggregates, sheets, and scattered single cells, and no particular cellular pattern is consistently observed. Therefore, this study aimed to determine whether the menstrual cycle affects the cellular pattern of HSILs, an effort to avoid false negatives due to the oversight of scattered small single HSIL cells in the cytological triage of human papillomavirus-positive women. METHODS A total of 147 HSIL samples of liquid-based cytology (LBC) in patients with cervical intraepithelial neoplasia grade 2 or 3 were obtained, and then, the relationship between cellular patterns, such as single-cell-like and syncytial aggregates, and menstrual cycles classified into six phases was analyzed. If a syncytial aggregate was present, the number of cells constituting the aggregate was visually counted under the microscope. RESULTS HSILs in scattered single cells and small sheets of <6 on LBC samples accounted for 43% (23/54) during the late proliferative phase of the menstrual cycle. A moderately strong statistically significant association was observed between cellular patterns and menstrual cycles (χ2 [3] = 9.423, p < 0.05) (Cramer's V = 0.253). The value of adjusted residuals showed a statistically significant increased proportion of single-cell-like patterns during the late proliferative phase (p < 0.01). CONCLUSIONS The present study demonstrated that HSIL cells in Pap smears in the late proliferation phase have a high frequency of single-cell-like patterns. In human papillomavirus-positive Pap smears with a clean background and predominantly superficial cells, careful microscopic observation by targeting single HSIL cells can potentially reduce false negatives.

Abstract
OBJECTIVES False-negatives on cytology may be observed during follow-up of patients with persistent cervical intraepithelial neoplasia (CIN); however, the underlying reasons are unknown, and the intra-individual variability of false-negatives and menstrual cycle has not been elucidated. Therefore, this study aimed to determine whether the menstrual cycle influences cytological results to maximize the accuracy. METHODS A total of 154 liquid-based cytological (LBC) samples during the follow-up of 26 patients with CIN were obtained, and then, the relationship between cytological results and menstrual cycles classified into six phases was analyzed. RESULTS All LBC smears were satisfactory, and 20 of 154 (13.0%) specimens were negative for intraepithelial lesions or malignancy (NILM). A statistically significant association was observed between the cytological results and menstrual cycles, χ2(2) = 19.322, p < 0.01. The association was moderately strong (Cramer's V = 0.354). The value of adjusted residuals showed a statistically significant increase in the NILM percentage as a cytological result at the early secretory phase (p < 0.01) and a statistically significant decrease in NILM at the menstrual and proliferative phases (p < 0.01). CONCLUSIONS The present study revealed that false-negative cytological results were found to more likely occur at the early secretory phase. More careful and precise microscopic observation of Pap smears collected at the early secretory phase may contribute to reducing the occurrence of false-negatives and improving the cytological sensitivity.

Effects of Menstrual Cycle on the Accumulation of Human Papillomavirus-Infected Cells Exfoliated from the Cervix That Drift into the Vagina. Microorganisms 2022; 10:microorganisms10040693. [PMID: 35456745 PMCID: PMC9029653 DOI: 10.3390/microorganisms10040693] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Revised: 03/15/2022] [Accepted: 03/23/2022] [Indexed: 11/17/2022] Open
Abstract
Human papillomavirus (HPV) testing using self-collected vaginal specimens is the preferred choice to increase screening uptake. Although the HPV testing results of these samples depend on the cells that naturally exfoliate from the cervical lesion and drift into the vagina, the mechanism of when and how these exfoliated cells mix with the self-collected sample remains unclear. Hence, the study aimed to clarify the relationship between the vaginal drift of HPV-infected cells exfoliated from the cervix, and the menstrual cycle. A total of 180 scraped samples of the cervix and vagina were examined. The exfoliated cells were classified into two categories according to the HPV genotyping results of each sample: sufficient accumulation (same HPV types in cervical and vaginal samples) and insufficient accumulation (fewer HPV types in vaginal samples than in cervical samples, or HPV positivity in cervical samples and HPV negativity in vaginal samples). A moderately strong statistically significant association was observed between exfoliated cell accumulation and the menstrual cycle, and insufficient accumulation was statistically significantly increased at the early proliferative phases. Self-collection of vaginal samples at the early proliferation phase indicates insufficient sample quantities or lower viral load, thereby affecting HPV genotyping.

Abstract
Great interest has been directed towards the use of first-void (FV) urine as a liquid biopsy for high-risk HPV DNA testing. The aim of this study was to investigate the potential effect of a first generation FV urine collection device on the detection of HPV DNA and to assess if the concentration of HPV DNA varies between FV urine collected in the morning and those collected later during the day. In this prospective cohort study, 33 self-reported HPV-positive women participated. An FV urine sample was collected by these women in the morning (first urine of the day) and another sample was collected later that day for four consecutive days using two different collection methods; i.e., the Colli-Pee® and a standard urine cup. Samples were collected at home and returned at ambient temperature to the laboratory by postal mail. HPV DNA testing was conducted with the Riatol qPCR HPV genotyping assay. Based on the combined generalized linear mixed model used, there was no significant impact of the timing of collection (morning versus later during the day) on copies of HPV DNA, whereas Colli-Pee® collected samples show higher HPV concentrations than cup collected samples. However, at high concentrations of hDNA, the benefit of the Colli-Pee® disappeared.

Daily self-sampling for high-risk human papillomavirus (HR-HPV) testing. J Clin Virol 2015; 73:1-7.

Abstract
BACKGROUND Self-sampling for HPV as part of primary screening is a well-tolerated method for women not attending organized Pap smear screening and could increase coverage of cervical cancer screening. OBJECTIVE To investigate if the prevalence of HR-HPV varies from day to day in infected women and if one single sample is reliable for detecting an ongoing infection. STUDY DESIGN This is a prospective cohort study on 12 premenopausal and 13 postmenopausal women performing daily self-sampling for HR-HPV testing. They were all HR-HPV-positive 1-3 months ago. Postmenopausal women were sampled for 28 days and premenopausal women sampled during bleeding-free days in one menstrual cycle. A possible difference in viral load between the estrogen-dominated proliferative phase and the progesterone-dominated secretory phase was analyzed. RESULTS AND CONCLUSIONS Consistent results throughout the sampling period were observed for 19 women, with either a daily presence of HPV (14 women) or no HPV at all during the sampling period (5 women). Of 607 samples from 25 women, 596 were consistently positive or negative for HPV during the sampling period and 11 were inconsistent (2%). There was no difference in HPV copy number between the estrogen dominated proliferative or progesterone dominated secretory menstrual cycle phases. The major finding was a high degree of consistency concerning HR-HPV positivity and negativity of HR-HPV in vaginal fluid during a sustained period of daily self-sampling. It does not appear to matter whether the sample is collected in the proliferative or secretory phase.

Abstract
BACKGROUND Current evidence on the relationship between human papillomavirus (HPV) DNA detection and menstrual cycle has been inconsistent. METHODS We included 21 nonoral contraceptive pill (non-OCP) users who self-collected vaginal samples twice per week for 16 weeks. We explored whether variable detection of HPV DNA exhibited cyclic or other structured temporal patterns. We also evaluated relationships between serial HPV prevalence, sexual behavior, and suspected bacterial vaginosis (BV) as defined by Nugent Gram stain score ≥7. RESULTS During follow-up, any-type HPV prevalence varied between 61.1% and 85.0%. Although not statistically significant, we observed a maximum autocorrelation in serial HPV prevalence lagging 14 days (correlation coefficient [ρ], -0.24). Any-type HPV detection had a periodic behavior, generally repeating every 28.0 days (bootstrapped interquartile range, 22.4-28.0) and peaking around the ovulation time (adjusted odds ratio, 1.96; 95% confidence interval [CI], 1.06-3.62) as compared to menstruation. We also showed that an increase in any-type HPV prevalence preceded the beginning of a menstrual cycle by 9-12 days. There was no evidence of relationships between HPV prevalence and sexual activity or Nugent score. CONCLUSIONS Serially detected any-type HPV DNA showed a periodic behavior and was likely to peak in the periovulatory phase among non-OCP users.

Abstract
OBJECTIVES In many settings, human papillomavirus (HPV) DNA testing already plays an important role in cervical cancer screening. It is unclear whether hormonal fluctuations associated with menstrual phase or oral contraceptive (OC) use have any effect on HPV detection. We evaluated the effects of OC use and timing of cervical sampling in relation to women's last menstrual period (LMP) on HPV detection, and viral load in the Brazilian Ludwig-McGill cohort study. METHODS Women in the cohort were followed every 4-6 months, and at each clinic visit they were asked to complete a questionnaire and to provide a cervical sample for HPV testing. Specimens from 6093 patient visits (n=2209 women) were categorised according to date of LMP into four distinct phases: follicular (days 5-9), midcycle (days 10-15), luteal (days 16-22), or late luteal (days 23-31). RESULTS Compared with follicular phase (referent group), HPV detection did not differ according to reported LMP for midcycle (OR=1.14, 95% CI 0.95 to 1.37), luteal (OR=1.03, 95% CI 0.85 to 1.25), or late luteal menstrual phase (OR=1.01, 95% CI 0.83 to 1.24), and was also not influenced by OC use. Analyses restricted to high-risk HPV types (grouped) and HPVs 16 and 18 (separately), produced similar non-significant associations. For HPV-positive samples, we found that the menstrual phase did not influence the total viral load. CONCLUSIONS These results indicate HPV detection is not associated with menstrual phase. Our findings suggest that standardising the timing of specimen collection for HPV testing is not necessary.

Abstract
OBJECTIVE To estimate the effect of the menstrual cycle and oral contraceptive pill (OCP) use on the prevalence, incidence, and persistence of human papillomavirus (HPV). METHODS A longitudinal study was conducted among 2,065 women aged 18-29 years. The women returned a self-collected cervicovaginal sample and filled out a questionnaire. A total of 1,812 women participated at all three time points, month 0, month 6, and month 12. RESULTS Low- and high-risk HPV prevalence at study entry was 8.9% and 11.8%, respectively. The annual incidence of low-risk HPV infections was 12.5% and the persistence was 2.0%. For high-risk HPV, the incidence and persistence was 12.1% and 4.5%, respectively. These results did not differ between OCP users and nonusers. A significant relationship between high-risk HPV detection and the timing of sampling was found when OCP users and nonusers were analyzed separately. In the second half of the menstrual cycle, high-risk HPV detection decreased in nonusers (P=.007) and increased in OCP users (P=.021). When women used OCPs continuously, high-risk HPV detection returned to the level of the first half of the menstrual cycle. CONCLUSION High-risk HPV detection was significantly influenced by sample timing in the menstrual cycle when analyzed separately for OCP users and women with a natural menstrual cycle. This may have implications in the future, when high-risk HPV detection may become a primary screening tool in cervical cancer prevention. LEVEL OF EVIDENCE II.

Abstract
OBJECTIVE To provide updated management guidelines according to cervical cytology specimen adequacy and techniques to optimize adequacy based on literature review and expert opinion. MATERIALS AND METHODS Selected members of the American Society for Colposcopy and Cervical Pathology committee and invited experts conducted a literature review and discussed appropriate management and areas for future research emphasis. RESULTS The guidelines recommend a repeat Pap test in a short interval of 2 to 4 months for most women when the cytology result is unsatisfactory. The preferred follow-up for women with a negative cytology result lacking an endocervical/transformation zone component or showing other quality indicators is a repeat Pap test in 12 months. Indications for an early repeat Pap test in 6 months are provided, and the influence of human papillomavirus testing results on management is discussed. Techniques for optimizing specimen adequacy are provided in detail. CONCLUSION The specimen adequacy management guidelines will help promote uniform and optimal follow-up of patients receiving cervical cytology screening. The topics for future research emphasis will be helpful in promoting studies in needed areas.

Abstract
Human immunodeficiency virus (HIV)-positive women have high rates of cervical squamous intraepithelial lesions (SIL) and concurrent human papillomavirus (HPV) infections with a variety of genotypes whose oncogenic risk is poorly documented. The prevalence and persistence of HPV genotypes and HPV16 variants were analysed in 112 HIV-positive and 115 HIV-negative Italian women. HIV-positive women were more likely than HIV-negative women to be infected by HPV at the initial examination (39.3 vs 13.9 %, P<0.001) and to have a higher period prevalence of HPV infection over a 3-year follow-up (43.8 % vs 17.4 %, P<0.001), regardless of CD4+ cell counts and anti-retroviral therapy. 'High-risk' and 'probable high-risk' HPVs (types 16, 18, 31, 33, 35, 45, 52, 58 and 66), among the 20 different viral genotypes identified, were predominant in HIV-positive (33.9 %) compared with HIV-negative (13.9 %) women. Among HIV-infected women, with normal cytology as well as with SIL of any grade, the most common genotypes were HPV16 followed by HPV81, -58, -72, -33 and -62. HPV16 isolates from 18 HIV-positive and eight HIV-negative women were classified into variant lineages based on sequencing analysis of E6 and E7 genes and the long control region. Whilst the HPV16 G350 European variant was prevalent in both HIV-positive (10.7 %) and -negative women (3.5 %), HPV16 African 2 variant was only detected in HIV-positive women (3.6 %), suggesting different sexual mixing behaviours. The increased prevalence of uncommon viral genotypes and HPV16 variants in HIV-positive Italian women underscores the need to target a wide range of HPV types in cervical screening of high-risk women.

Abstract
INTRODUCTION The Hybrid Capture II (HC II, Digene) high-risk human papilloma virus (HPV) (hrHPV) DNA test is an in vitro nucleic acid hybridization assay that uses enhanced chemiluminescence for the qualitative and semiquantitative detection of hrHPV in cervical samples. Patient samples are concomitantly tested with positive and negative DNA controls and results reported as positive or negative on the basis of a ratio of relative light units to a cutoff value derived from the positive control (RLU/CO). Samples with a ratio <1.0 RLU/CO are expressed as negative for hrHPV, samples with a ratio >2.5 RLU/CO are expressed as positive for hrHPV, and samples with a ratio between these numbers are submitted for retesting. These "equivocal" values are resulted as positive for hrHPV if either of 2 subsequent test values equals or exceeds 1.0 RLU/CO. Samples that show <1.0 RLU/CO after 2 repeat tests are resulted as negative for hrHPV. METHODS In this study, we evaluated all hrHPV test results over a 17-month period in our institution. Initial tests showing an equivocal result were analyzed for final retesting result, and for all corresponding and subsequent cytology and histology results. All hrHPV tests were conducted on SurePath (TriPath) or ThinPrep (Cytyc) cervical cytology specimens using the HC II hrHPV DNA test. Subsequent hrHPV tests also were correlated with incident and follow-up findings. RESULTS A total of 4792 hrHPV test results were evaluated. Of these, 191 (4%) showed equivocal initial results. When retested, 178 of the 191 samples (93%) resulted positive for hrHPV on first retest and an additional 8 resulted positive for hrHPV on the second retest, bringing the total positive tests to 186 out of 191 (97.4%). Five samples (2.6%) out of 191 were finally expressed as negative for hrHPV. Corresponding cytologic interpretations for the 191 specimens were as follows: NILM-30, atypical squamous cell of undetermined significance (ASC-US)-138, atypical squamous cells--cannot exclude HSIL-13 (ASC-H-13), LSIL-9, and high-grade squamous intraepithelial lesion (HSIL)-1. Follow-up histology was available for 60 of the 191 equivocal cases and showed cervical intraepithelial neoplasia (CIN) II or CIN III in 7 cases, CIN I in 13 cases, and negative or reactive changes in 40 cases. CONCLUSIONS On the basis of the results, repeat testing of equivocal specimens might not be necessary as these specimens are overwhelmingly found to be positive for hrHPV. Additionally, hrHPV tests falling in the equivocal range should be considered as definite positive tests, as follow-up results in this cohort demonstrate that significant histologic abnormalities are associated with 10.5% of these cases (20/191), and with 33% of those biopsied (20/60) cases.
