Maternal HPV Infection: Effects on Pregnancy Outcome.

The human papilloma virus (HPV) infection, caused by a ubiquitous virus typically transmitted through the direct contact of infected organs, either through the skin or mucosa, is the most common sexually transmitted infection, placing young women at a high risk of contracting it. Although the vast majority of cases spontaneously clear within 1-2 years, persistent HPV infection remains a serious concern, as it has repeatedly been linked to the development of multiple malignancies, including cervical, anogenital, and oropharyngeal cancers. Additionally, more recent data suggest a harmful effect of HPV infection on pregnancy. As the maternal hormonal environment and immune system undergo significant changes during pregnancy, the persistence of HPV is arguably favored. Various studies have reported an increased risk of adverse pregnancy outcomes among HPV-positive women, with the clinical impact encompassing a range of conditions, including preterm birth, miscarriage, pregnancy-induced hypertensive disorders (PIHD), intrauterine growth restriction (IUGR), low birth weight, the premature rupture of membranes (PROM), and fetal death. Therefore, understanding the mechanisms employed by HPV that negatively impact pregnancy and assessing potential approaches to counteract them would be of interest in the quest to optimize pregnancy outcomes and improve child survival and health.

HPV16 Entry into Epithelial Cells: Running a Gauntlet.

During initial infection, human papillomaviruses (HPV) take an unusual trafficking pathway through their host cell. It begins with a long period on the cell surface, during which the capsid is primed and a virus entry platform is formed. A specific type of clathrin-independent endocytosis and subsequent retrograde trafficking to the trans-Golgi network follow this. Cellular reorganization processes, which take place during mitosis, enable further virus transport and the establishment of infection while evading intrinsic cellular immune defenses. First, the fragmentation of the Golgi allows the release of membrane-encased virions, which are partially protected from cytoplasmic restriction factors. Second, the nuclear envelope breakdown opens the gate for these virus-vesicles to the cell nucleus. Third, the dis- and re-assembly of the PML nuclear bodies leads to the formation of modified virus-associated PML subnuclear structures, enabling viral transcription and replication. While remnants of the major capsid protein L1 and the viral DNA remain in a transport vesicle, the viral capsid protein L2 plays a crucial role during virus entry, as it adopts a membrane-spanning conformation for interaction with various cellular proteins to establish a successful infection. In this review, we follow the oncogenic HPV type 16 during its long journey into the nucleus, and contrast pro- and antiviral processes.

Detection of Human Papillomavirus in Papillary Thyroid Carcinoma and its Association with Tumor Staging and Pathologic Features.

Background: The role of human papillomavirus (HPV), as a common infection, has been evaluated in many cancers such as the cervix and squamous cell carcinoma of the head and neck. To the best of our knowledge, for the first time, the association of HPV with papillary thyroid carcinoma (PTC) and its pathologic features are investigated. Methods: A retrospective cross-sectional study was conducted from May 2014 to January 2018 in several hospitals affiliated to Shiraz University of Medical Sciences, Shiraz, Iran. Thyroid tissue specimens of patients diagnosed with PTC (n=82) and benign thyroid nodules (n=77) were collected using the consecutive sampling method. The presence of HPV in PTC, adjacent normal tissue, and benign thyroid nodules was evaluated using the polymerase chain reaction (PCR) method. The frequency of HPV positivity in PTC tissues was compared with benign thyroid nodules and adjacent normal tissue. Association of pathologic features of PTC with HPV positivity was also investigated. Data were analyzed using SPSS version 21.0, and P values less than 0.05 were considered statistically significant. Results: HPV PCR positivity was observed in 3.8% of benign thyroid nodules and 13.4% of PTC samples but in none of the adjacent normal tissues. After adjustment for age and sex, the prevalence of HPV PCR positivity in the PTC tissues was significantly more than the benign thyroid nodules (P=0.015). The prevalence was also significantly higher than the adjacent normal tissues (P<0.001). Conclusion: There was a significant association between PTC and HPV positivity. Further studies are required to determine the cause and effect of the association between these two conditions.

The prevalence of HR-HPV infection based on self-sampling among women in China exhibited some unique epidemiologic features.

Objective To investigate the epidemiological characteristics of high-risk human papillomavirus(HR-HPV) infection based on vaginal self-collected samples. Study Design and Setting The pooled data of 3045 self-collected samples used for the analysis derived from four previous studies on cervical cancer screening(The Chinese Multi-Center Screening Trial, CHIMUST; The Shenzhen Cervical Cancer Screening Trial-2, SHENCCAST-2; The Chinese Cervical Cancer Prevention Study, CHIPCAPS; Pingshan trial, PINGSHAN)conducted across China by our team since 2011. These cases were evaluated for HR-HPV type prevalence relative to lesion grade and age. The occurrence of cervical intraepithelial neoplasia(CIN) with specific HPV types and the influence of co-infection is explored. Results The top three most common genotypes among the HR-HPV positives were HPV-52(23.4%), HPV-16(18.0%), and HPV-58(15.50%). For women with CIN2+, the most frequent genotypes were HPV-16, 58, 52, and 18 in sequence. HPV-16 accounted for the majority of CIN2/CIN3/Ca with attribution rate of 23.86%, 44.78% and 50.00% respectively. HPV-58 accounted for 19.48%, 16.79% and 13.46% respectively. CIN2+ was found in the following types most frequently: HPV-16(31.23%), HPV-33(24.03%), HPV-58(18.41%), HPV-31(11.76%), HPV-18(7.75%), and HPV-52(7.30%). HPV-16 showed preference for co-infection with HPV-52 and HPV-58. Conclusion The prevalence of HR-HPV infection based on self-sampling among women in China exhibited some unique epidemiologic features.

Effect of Training Pediatric Clinicians in Human Papillomavirus Communication Strategies on Human Papillomavirus Vaccination Rates: A Cluster Randomized Clinical Trial.

Importance: Missed opportunities for human papillomavirus (HPV) vaccination during pediatric health care visits are common. Objectives: To evaluate the effect of online communication training for clinicians on missed opportunities for HPV vaccination rates overall and at well-child care (WCC) visits and visits for acute or chronic illness (hereafter referred to as acute or chronic visits) and on adolescent HPV vaccination rates. Design, Setting, and Participants: From December 26, 2018, to July 30, 2019, a longitudinal cluster randomized clinical trial allocated practices to communication training vs standard of care in staggered 6-month periods. A total of 48 primary care pediatric practices in 19 states were recruited from the American Academy of Pediatrics Pediatric Research in Office Settings network. Participants were clinicians in intervention practices. Outcomes were evaluated for all 11- to 17-year-old adolescents attending 24 intervention practices (188 clinicians) and 24 control practices (177 clinicians). Analyses were as randomized and performed on an intent-to-treat basis, accounting for clustering by practice. Interventions: Three sequential online educational modules were developed to help participating clinicians communicate with parents about the HPV vaccine. Weekly text messages were sent to participating clinicians to reinforce learning. Statisticians were blinded to group assignment. Main Outcomes and Measures: Main outcomes were missed opportunities for HPV vaccination overall and for HPV vaccine initiation and subsequent doses at WCC and acute or chronic visits (visit-level outcome). Secondary outcomes were HPV vaccination rates (person-level outcome). Outcomes were compared during the intervention vs baseline. Results: Altogether, 122 of 188 clinicians in intervention practices participated; of these, 120, 119, and 116 clinicians completed training modules 1, 2, and 3, respectively. During the intervention period, 29 206 adolescents (14 664 girls [50.2%]; mean [SD] age, 14.2 [2.0] years) made 15 888 WCC and 28 123 acute or chronic visits to intervention practices; 33 914 adolescents (17 069 girls [50.3%]; mean [SD] age, 14.2 [2.0] years) made 17 910 WCC and 35 281 acute or chronic visits to control practices. Intervention practices reduced missed opportunities overall by 2.4 percentage points (-2.4%; 95% CI, -3.5% to -1.2%) more than controls. Intervention practices reduced missed opportunities for vaccine initiation during WCC visits by 6.8 percentage points (-6.8%; 95% CI, -9.7% to -3.9%) more than controls. The intervention had no effect on missed opportunities for subsequent doses of the HPV vaccine or at acute or chronic visits. Adolescents in intervention practices had a 3.4-percentage point (95% CI, 0.6%-6.2%) greater improvement in HPV vaccine initiation compared with adolescents in control practices. Conclusions and Relevance: This scalable, online communication training increased HPV vaccination, particularly HPV vaccine initiation at WCC visits. Results support dissemination of this intervention. Trial Registration: ClinicalTrials.gov Identifier: NCT03599557.

Dysregulation of autophagy-associated microRNAs in condyloma acuminatum.

Condyloma acuminatum, which is caused by low-risk human papillomavirus (lrHPV) infection, is one of the most common sexually transmitted diseases. Autophagy is thought to be associated with condyloma acuminatum, but how the autophagy process is regulated remains unclear. MicroRNAs (miRNAs) are important regulators of gene transcription that play a central role in many biological processes, including autophagy and viral infection. This study was designed to identify autophagy-related miRNAs and their targets in condyloma acuminatum and to validate their expression. The levels of the autophagy proteins microtubule-associated protein 1 light chain 3 (LC3) and P62/SQSTM1 (P62) were abnormally increased in the local lesion tissue of condyloma acuminatum patients compared with healthy controls. MiRNAs and their target mRNAs in condyloma acuminatum patients were analyzed by bioinformatics. Eighty-one differentially expressed miRNAs were identified, of which 56 were downregulated and 25 were upregulated. Two of the differentially expressed miRNAs associated with autophagy, miRNA-30a-5p and miRNA-514a-3p, were analyzed further, and their target genes were identified as autophagy-related protein (Atg) 5 and Atg12 and Atg3 and Atg12, respectively. The expression levels of miRNA-30a-5p and miRNA-514a-3p were decreased and those of Atg5, Atg12 and Atg3 were increased in condyloma acuminatum patients compared with healthy controls. In addition, miRNA-30a-5p and miRNA-514a-3p expression correlated with the proliferation index Ki-67 in condyloma acuminatum. Taken together, our results suggest that the changes in autophagy levels in patients with condyloma acuminatum may be related to the changes in miRNA-30a-5p and miRNA-514a-3p expression. This study provides a theoretical basis for identifying new mechanisms that link miRNAs, HPV infection and host autophagy in vivo.

Viral infections and implications for male reproductive health.

Viral infections have haunted humankind since times immemorial. Overpopulation, globalization, and extensive deforestation have created an ideal environment for a viral spread with unknown and multiple shedding routes. Many viruses can infect the male reproductive tract, with potential adverse consequences to male reproductive health, including infertility and cancer. Moreover, some genital tract viral infections can be sexually transmitted, potentially impacting the resulting offspring's health. We have summarized the evidence concerning the presence and adverse effects of the relevant viruses on the reproductive tract (mumps virus, human immunodeficiency virus, herpes virus, human papillomavirus, hepatitis B and C viruses, Ebola virus, Zika virus, influenza virus, and coronaviruses), their routes of infection, target organs and cells, prevalence and pattern of virus shedding in semen, as well as diagnosis/testing and treatment strategies. The pathophysiological understanding in the male genital tract is essential to assess its clinical impact on male reproductive health and guide future research.

Longitudinal Voice Outcomes Following Serial Potassium Titanyl Phosphate Laser Procedures for Recurrent Respiratory Papillomatosis.

OBJECTIVE: Repeated surgical interventions are usually required to control recurrent respiratory papillomatosis (RRP), but at considerable risk of worsened postoperative voice quality. Potassium titanyl phosphate (KTP) laser has been reported to effectively manage RRP; however, voice quality after repeated procedures has not been investigated. METHODS: This study recruited 16 patients with RRP treated using KTP laser between 2013 and 2019. KTP laser procedures were performed under general anesthesia via direct suspension laryngoscope or under local anesthesia via flexible endoscope, depending on the need for pathological proof, patient tolerance, and lesion size and location. Disease control was investigated by videolaryngostroboscopy. Voice outcome was evaluated using a 10-item voice handicap index (VHI-10), acoustic and perceptual analyzes. RESULTS: We reviewed the medical records of 11 male and 5 female patients with RRP (age range: 23-73 years). Five patients received KTP laser once, six patients received it 2 to 5 times, and five patients received 6 to 15 procedures. Median VHI-10 decreased from 28.3 to 12.0 points after the initial procedure and were maintained at 10.1 to 11.0 points following subsequent procedures (P < .01, generalized estimating equation). Acoustic and perceptual analysis of voice quality also revealed significant improvements (P < .01), which remained stable even after 6 to 10 KTP laser procedures. Minor adverse events included slight fibrotic change of vocal folds and glottic web, but these did not significantly alter postoperative voice quality. CONCLUSION: This longitudinal follow-up study revealed that serial KTP laser procedures can effectively control RRP while preserving phonatory function and maintaining adequate voice quality. LEVEL OF EVIDENCE: 4.

Differential Wnt-ß- catenin pathway activation in HPV positive and negative oral epithelium is transmitted during head and neck tumorigenesis: clinical implications.

The aim of this study is to understand the association of HPV infection and wnt-ß-catenin self-renewal pathway in development of head and neck squamous cell carcinoma (HNSCC). For this reason, the molecular profiles (methylation/deletion/expression) of antagonists (SFRP1/2 and DKK1), agonists (FZD7 and LRP6) and effector protein ß-catenin of the pathway were analyzed in HPV positive/negative oral epithelium at first, followed by its changes during development of the tumor along with correlations with different clinico-pathological parameters. HPV infection alone or in combination with tobacco habit could activate p- ß-catenin expression in basal/parabasal layers of oral epithelium through high expression of FZD7 and significant down regulation of SFRP1/2 through promoter hypermethylation due to over expression of DNMT1 with ubiquitous down regulation of DKK1 and up-regulation of LRP6. This phenomenon has been seen in respective HPV positive and negative HNSCC tumors with additional deletion/microsatellite size alterations in the antagonists. Overall alterations (methylation/deletion) of SFRP1/2, DKK1 gradually increased from Group I (HPV-/Tobacco-) to Group IV(HPV+/Tobacco+) tumors, leading to the worst prognosis of the patients. Thus, the transmission of differentially activated wnt-ß-catenin pathway from HPV positive/negative basal/parabasal layers of oral epithelium to HNSCC tumors determines differences in molecular pathogenesis of the disease.

Effectiveness of an Educational Intervention to Increase Human Papillomavirus Knowledge and Attitude in Staff and Nursing Students.

PURPOSE: To evaluate the effect of education about human papilloma virus and its vaccine on awareness and attitude of healthcare workers and nursing students. DESIGN: This was a quasi-experimental study. METHODS: The sample size was 250 (155 healthcare workers and 95 students), and both groups received educational intervention. Questionnaires were used to collect data before, after, and also 3 months following the intervention. FINDINGS: The mean age of participants was 30.1 ± 10.23 years. Results showed a significant increase in knowledge (P < .001), overall attitude (P = .000), and perceived behavior (P < .001) of the participants after the educational intervention. CONCLUSION: Educational intervention was effective in knowledge, attitude, and behavior of students and healthcare workers. CLINICAL EVIDENCE: Educational intervention can be one of the strategies to prevent individuals from acquiring the virus and to increase vaccine compliance.

The relationship between the presence of HPV infection and biofilm formation in cervicovaginal smears.

PURPOSE: To demonstrate and understand the association of HPV infection and biofilm formation. METHODS: The study consisted of cervicovaginal samples of 72 women who were evaluated at the colposcopy unit. Papanicolaou staining was used for cytological examination while "Crystal Violet Binding" assay was performed to detect biofilm formation. RESULTS: HPV-DNA was positive in 55.5% (n = 40) of the patients. The biofilm formation rate was statistically significantly higher in the HPV-positive women (45%) compared to HPV-negative women (21.9%) (P < 0.05). There was a statistically significant relationship between the presence of single HPV and "high-risk HPV" types and biofilm formation (P < 0.05). Biofilm formation was found in 80% of women with abnormal smear demonstrating atypical epithelial cells (P < 0.05). CONCLUSION: Biofilm formation is more frequent at the cervicovaginal microbiota of patients with HPV infection. This finding is especially important in cases with atypical epithelial cells at their cervicovaginal smears.

Effects on Vaginal Microbiota Restoration and Cervical Epithelialization in Positive HPV Patients Undergoing Vaginal Treatment with Carboxy-Methyl-Beta-Glucan.

OBJECTIVE: Evaluate the effects of carboxy-methyl-beta-glucan on cervical epithelialization and on the vaginal microbiota in patients with HPV infection or low-grade cervical preneoplastic lesion (CIN 1). MATERIALS AND METHODS: Seven-hundred eighty-four women with positive HPV tests or diagnosed with CIN 1 were enrolled in a retrospective case-control study. All the recruited women performed, at baseline and after 6 months, Pap test, HPV test, evaluation of vaginal health according to the Amsel criteria, colposcopy, and punch biopsy. The study population was then divided into 2 groups in relation to the therapy performed during the follow-up period. Group A performed treatment with vaginal gel based on carboxy-methyl-beta-glucan (1 application/day for 20 days per month for 3 months). Group B was the control group. RESULTS: The patients of group A had a significant improvement in the ectopia pattern and a greater number of cases with metaplasia in the maturation phase with a significant increase in Lugol uptake. In the experimental group, a significant improvement in the pH indices, a negative Swift test and a resolution of the leucorrhoea were observed. A negative result of the 37.1% Pap test and the 39.9% HPV test (vs. 15.2% and 16.5%, respectively) were demonstrated in the treatment group with respect to the control group. A negativization of the colposcopic pictures was observed with a reduction in the amount of CIN 1 found higher in the treatment group. CONCLUSIONS: Vaginal therapy based on carboxy-methyl-beta-glucan has been able to improve overall vaginal health; this effect seemed to positively impact the risk of persistence and progression of CIN.

Fifteen new nucleotide substitutions in variants of human papillomavirus 18 in Korea : Korean HPV18 variants and clinical manifestation.

High-risk human papillomavirus (HPV) infection is an essential factor for the development of cervical cancer. HPV18 is the second most common carcinogenic HPV type following HPV16, but the lineages of HPV18 have been less well studied than those of HPV 16. The purpose of this study was to analyze the nucleotide variants in the E6, E7, and L1 genes of HPV18, to assess the prevalence of HPV18 variants in Korea and to explore the relationship between HPV18 genetic variants and the risk for cervical cancer.A total of 170 DNA samples from HPV18-positive cervical specimens were collected from women admitted to a secondary referral hospital located in Seoul. Among them, the lineages of the 97 samples could be successfully determined by historical nomenclature.All the studied HPV 18 variants were lineage A. Sublineages A1 and A4 comprised 91.7% (89/97) and 1.0% (1/97), respectively. Sublineages other than A1 or A4 comprised 7.2% (7/97). We identified 15 new nucleotide substitutions among 44 nucleotide substitutions: C158T, T317G, T443G, A560G, A5467G, A5560C, A5678C, A6155G, G6462A, T6650G, G6701A, T6809C, A6823G, T6941C and T6953C. Among them, 6 substitutions at positions 317, 443, 5467, 5560, 6462, and 6823 resulted in amino acid changes (E6: F71L and N113K; L1: H13R, H44P, A345T, and N465S, respectively). The pathologic results were classified as normal in 25.8% (25/97) of the women, atypical squamous cells of undermined significance (ASCUS) in 7.2% (7/97), cervical intraepithelial neoplasia (CIN) 1 in 36.1% (35/97), CIN2/3 in 19.6% (18/97), and carcinoma in 12.4% (12/97). There was no significant association between the HPV18 sublineages and the severity of pathologic lesion or the disease progression.This study is the first to analyze the distribution of HPV18 variants in Korean and to associate the results with pathologic findings. Although the HPV18 variants had no significant effect on the degree and progression of the disease, the newly discovered nonsynonymous mutation in L1 might serve as a database to determine vaccine efficacy in Korean women.

Quality of Life for Women with Human Papillomavirus-induced Lesions.

OBJECTIVE: To reveal the changes in the quality of life reported by women with Human papillomavirus (HPV)-induced lesions. METHODS: This is a cross-sectional, descriptive-exploratory study of a qualitative approach performed from June to August 2016. Semi-structured face-to-face interviews based on five questions on the concept of quality of life were used. The data were submitted to thematic analysis. All ethical aspects have been contemplated. RESULTS: A total of 20 women aged between 25 and 59 years old were interviewed. From the analysis of the data, the following thematic units emerged: physical and emotional changes, especially complaints of pruritus, discharge and pain, worry, fear, shame and sadness; changes in sexual and affective relationships with decreased libido, dyspareunia and interruption of sexual activity; changes in social relationships resulting in absenteeism at work. CONCLUSION: Human papillomavirus infection impairs the quality of life of women as it significantly affects sexual, affective, physical, emotional, and everyday habits. Therefore, HPV infection can lead to exponential changes in the quality of life of women, which can be mitigated by the availability of sources of support such as family, friends and the multi-professional team, helping to improve knowledge and cope with HPV.

Portanto, a infecção pelo HPV pode acarretar mudanças exponenciais na qualidade de vida de mulheres, as quais podem ser amenizadas pela disponibilidade de fontes de apoio, como família, amigos e equipe multiprofissional, que auxiliam no nível de conhecimento e enfrentamento do HPV.

Protein Phosphorylation in Serine Residues Correlates with Progression from Precancerous Lesions to Cervical Cancer in Mexican Patients.

Protein phosphorylation is a posttranslational modification that is essential for normal cellular processes; however, abnormal phosphorylation is one of the prime causes for alteration of many structural, functional, and regulatory proteins in disease conditions. In cancer, changes in the states of protein phosphorylation in tyrosine residues have been more studied than phosphorylation in threonine or serine residues, which also undergo alterations with greater predominance. In general, serine phosphorylation leads to the formation of multimolecular signaling complexes that regulate diverse biological processes, but in pathological conditions such as tumorigenesis, anomalous phosphorylation may result in the deregulation of some signaling pathways. Cervical cancer (CC), the main neoplasm associated with human papillomavirus (HPV) infection, is the fourth most frequent cancer worldwide. Persistent infection of the cervix with high-risk human papillomaviruses produces precancerous lesions starting with low-grade squamous intraepithelial lesions (LSIL), progressing to high-grade squamous intraepithelial lesions (HSIL) until CC is generated. Here, we compared the proteomic profile of phosphorylated proteins in serine residues from healthy, LSIL, HSIL, and CC samples. Our data show an increase in the number of phosphorylated proteins in serine residues as the grade of injury rises. These results provide a support for future studies focused on phosphorylated proteins and their possible correlation with the progression of cervical lesions.

Use of intralesional cidofovir in the recurrent respiratory papillomatosis: a review of the literature.

OBJECTIVE: Recurrent respiratory papillomatosis (RRP) is characterized by exophytic, benign, and papillary lesions infected by the virus in the epithelium of the upper aerodigestive tract. RRP is caused by persistent infection of the respiratory epithelium by human papillomavirus (HPV) HPV6 and-11. The clinical course of RRP is unpredictable, frequently relapsing, and may be lifelong. The aim of this study is to evaluate the efficacy and safety of the use of intralesional Cidofovir in the treatment of RRP. PATIENTS AND METHODS: We have selected articles on the use of cidofovir as adjuvant therapy in laryngeal papillomatosis. We reviewed 20 reports that enrolled 185 patients with "adult onset recurrent respiratory papillomatosis" (AORRP) and 85 patients with "juvenile onset recurrent respiratory papillomatosis" (JORRP). We evaluated concentration of cidofovir, number of injections, injection interval, therapeutic response, side effects, and progression to dysplasia. RESULTS: The mean concentration of cidofovir was 7.5 mg/ml at injection. The mean number of injections per patient is 6 with 26 days between injections. The percentage of patients with dysplasia after use of cidofovir is 1.48%. The AORRP response to cidofovir is better with a 74% complete response rate, compared to 56.5% of the JORRP. CONCLUSIONS: Intralesion use of cidofovir has a good adjuvant action in RRP increasing the complete remission of the disease. The treatment does not increase the risk of laryngeal dysplasia.

Twelve-Year Trend in the Prevalence of High-Risk Human Papillomavirus Infection Among Rwandan Women Living With HIV.

BACKGROUND: We examined the trend in prevalence of high-risk human papillomavirus (hrHPV) cervical infection among Rwandan women living with HIV (WLWH) over 12 years. METHODS: Prevalence of cervical hrHPV DNA was measured in 3 studies at 3 different time periods in 3 different groups of WLWH using 3 different but comparable hrHPV tests: a MY09/MY11 PCR test in 2005 (RWISA; n = 497), careHPV in 2009-2010 (HPV Demonstration; n = 1242), and Xpert HPV test in 2016-2018 (U54; n = 4734). Prevalences were adjusted for age and CD4 cell count. RESULTS: HrHPV prevalence decreased over time from 42.5% to 32.2% to 26.5% (P < .001). CD4 cell counts improved over time (Ptrend <.001) so that the percentage of WLWH with CD4 counts of ≥500 cells/µL increased from 7.7% in 2005 to 42.2% in 2009-2010 and 61.1% in 2016-2018. Thus, after adjustment for differences in CD4 counts and age, hrHPV prevalences were more similar over time: 32.6% for RWISA, 30.6% for HPV Demonstration, and 27.1% for U54 (P = .007). CONCLUSIONS: Prevalence of hrHPV among WLWH has decreased over the past decade, most likely the result of improved immune reconstitution due to better HIV care and management in Rwanda.
