Risk of human papillomavirus infection in women with rheumatic disease: cervical cancer screening and prevention

Cervical cancer screening by cotesting method for Vietnamese women 25-55 years old: a cost-effectiveness analysis

BACKGROUND

Cervical cancer (CC) is preventable through regular screening and vaccination against human papillomavirus (HPV). However, CC remains a significant public health issue in low-income and middle-income countries (LMICs) like Vietnam, where financial constraints hinder the widespread implementation of HPV vaccination and screening programmes. Currently, Vietnam lacks both a national CC screening intervention and an HPV vaccination programme for women and girls. To date, cost-effectiveness studies evaluating CC screening methods in Vietnam remain limited.

OBJECTIVES

To evaluate the cost-effectiveness of two CC screening strategies for Vietnamese women aged 25-55 years: (1) cotesting combining cytology and HPV testing conducted three times at 5 year intervals (intervention) and (2) cytology-based screening conducted five times at 2 year intervals (comparator). The objective is to provide evidence to inform policy and clinical practice in Vietnam.

DESIGN

Cost-effectiveness analysis using a Markov model with 1 year cycles to simulate the natural progression of CC.

SETTING

The Vietnamese healthcare system, modelled from the provider's perspective, with parameters adapted to the local context through expert consultations.

PARTICIPANTS

A simulated cohort of Vietnamese women aged 25-55 years.

INTERVENTIONS

The intervention involved cotesting (cytology and HPV testing) three times at 5 year intervals. The comparator was cytology-based screening conducted five times at 2 year intervals.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome measure was quality-adjusted life years (QALYs). Costs and cost-effectiveness ratios were assessed using Vietnam's gross domestic product (GDP) per capita as the cost-effectiveness threshold (1-3 times GDP per capita). Sensitivity analyses (one-way deterministic and probabilistic) were conducted to account for uncertainties.

RESULTS

The cotesting strategy was less effective and more costly than cytology-based screening across all age groups. Cotesting resulted in higher costs and fewer QALYs than the comparator. Probabilistic sensitivity analyses confirmed that cotesting was not cost-effective under current conditions in Vietnam.

CONCLUSIONS

Cytology-based screening conducted five times at 2 year intervals is a more cost-effective option for CC screening in Vietnamese women aged 25-55 years. The cotesting strategy cannot be recommended due to its higher cost and lower effectiveness.

[Human papillomavirus and systemic lupus erythematosus: A systematic review]

BACKGROUND

Human papillomavirus (HPV) infections cause cancer of the cervix, vagina, vulva, anus, penis and upper respiratory tract. The prevention of HPV-induced cancers is a public health issue. Patients with systemic lupus are at increased risk of persistent HPV infection and cervical cancer due to treatment-induced immunosuppression. HPV vaccination and screening for precancerous lesions are two effective means of preventing cervical cancer. Despite the demonstrated safety and efficacy of the HPV vaccine, coverage of HPV vaccination in SLE adults remains low. Screening for cervical cancer is only carried out as recommended in one lupus patient in two. Catch-up HPV vaccination, therapeutic vaccination and vaginal self-sampling are innovative prevention strategies adapted to patients at risk of HPV-induced cancer.

CONCLUSIONS

Measures to prevent HPV-induced cancers are insufficiently implemented in patients managed for systemic lupus. Healthcare professionals and patients need to be made aware of the importance of HPV preventing vaccination.

Exploring the interaction mechanisms between cervical carcinoma in situ and antibody-mediated immune responses through Mendelian randomization analysis

OBJECTIVE

This study aims to investigate the causal relationship between cervical carcinoma in situ and antibody-mediated immune responses, providing a scientific basis for the prevention and treatment of cervical carcinoma in situ.

METHODS

A bidirectional Mendelian Randomization (MR) approach was utilized, leveraging two Genome-Wide Association Studies (GWAS) related to cervical carcinoma in situ and antibody-mediated immune responses to collect Single Nucleotide Polymorphism (SNP) data. Multiple statistical methods, including the inverse-variance weighted (IVW) method, MR-Egger regression, weighted median, and weighted mode, were utilized. Antibody-mediated immune response-related SNPs were used as instrumental variables (IVs) for a forward MR analysis of cervical carcinoma in situ, while cervical carcinoma in situ-related SNPs served as IVs for a reverse MR analysis of antibody-mediated immune responses.

RESULTS

The forward MR analysis revealed significant causal associations between two SNPs, GCST90006901 (P = 0.012, OR (95%CI) = 1.167(1.034-1.317)) and GCST90006909 (P < 0.001, OR (95%CI) = 1.805(1.320-2.467)), within antibody-mediated immune responses and the occurrence of cervical carcinoma in situ. The reverse MR analysis demonstrated that cervical carcinoma in situ exerts influence on multiple SNPs associated with antibody-mediated immune responses. Specifically, GCST90006891 (P = 0.018, OR (95%CI) = 1.164(1.027-1.319)) and GCST90006894 (P = 0.048, OR (95%CI) = 1.074 (1.001-1.153)) showed positive effects, while GCST90006899 (P = 0.022, OR (95%CI) = 0.935(0.882-0.990)) and GCST90006911 (P = 0.0193, OR (95%CI) = 1.226(1.034-1.454)) exhibited distinct trends of influence.

CONCLUSION

The Mendelian Randomization analysis indicates a clear causal relationship between antibody-mediated immune responses and the prevalence of cervical carcinoma in situ, with cervical carcinoma in situ also exerting a certain degree of influence on antibody-mediated immune responses. This finding provides important insights into the interaction mechanism between the two and suggests avenues for developing effective prevention and control strategies.

HPV Infection and Prevention in Patients With Immune-Mediated Inflammatory Diseases: A Scoping Review

BACKGROUND/HISTORICAL PERSPECTIVE

Human papillomavirus (HPV) infections are a significant public health concern as they cause various cancers, including those of the cervix, vulva, vagina, anus, penis, and oropharynx, in both women and men.

SUMMARY INTEGRATING THE CURRENT PUBLISHED LITERATURE

Individuals with immune-mediated inflammatory diseases, particularly systemic lupus erythematosus, have an increased risk of developing persistent HPV infection and subsequent precancerous lesions due to their immunosuppression.

MAJOR CONCLUSIONS

Vaccination and screening for precancerous lesions are 2 central management strategies that must be implemented in patients with immune-mediated inflammatory diseases. Although HPV vaccination has been proven to be safe and effective in these patients, coverage remains low and should be encouraged. Screening for cervical cancer should be more widely implemented in this population, as recommended in guidelines for other immunosuppressed patients.

FUTURE RESEARCH DIRECTIONS

Catch-up vaccination, vaginal self-sampling screening for HPV detection, and therapeutic vaccination are new options that should be considered.

Oral Mucosal Human Papillomavirus and Epstein-Bar Virus Rates in Patients with Dry Mouth and/or Sjögren's Syndrome in a Hungarian Cohort

PURPOSE

To find an association between oral mucosal human papilloma- and/or Epstein-Barr (HPV, EBV) virus infection in patients with dry mouth and/or Sjögren's syndrome (SS) compared to healthy controls and to find connections with salivary gland histopathological alterations.

MATERIALS AND METHODS

Ninety-two participants were divided into four groups: 1. healthy controls (n = 32); 2. xerostomia (n = 28); 3. hyposalivation (n = 22); and 4. SS groups (n = 10). To detect virus infection brush biopsy was outlined in all groups. Detections of virus-specific sequences were achieved with polymerase chain reaction (PCR). Lip biopsy and histopathological assessment was performed in groups 2, 3 and 4.

RESULTS

HPV positivity of oral mucosal cells was shown in group 1: 1 (3.12%); group 2: 3 (10.7%); group 3: 2 (8.26%); and in group 4: 0 of the samples. EBV was present in group 1: 14 (43.7%); group 2: 17 (60.7%); group 3: 6 (27.3%); and in group 4: 5 (50%) of the cases. There was no statistically significant difference between the attributes. Intact salivary gland in 28.2%, chronic sialadenitis in 28.2%, stromal fibrosis in 6.5%, lipomatous atrophy in 8.6%, fibrous atrophy in 6.5% and positive focus score (SS) in 26.1% were found in the subjects. Neither HPV nor EBV infection caused statistically significantly more histological abnormalities.

CONCLUSION

Orofacial mucosal HPV and/or EBV DNA rates did not differ statistically significantly in patients with xerostomia or hyposalivation or SS compared to healthy controls, therefore, it cannot prove the provocative role of these viruses in dry mouth and/or SS. Neither dry mouth nor SS were accompanied by statistically significantly more salivary gland alterations in HPV- and/or EBV-positive subjects; these alterations are frequent in the virus-negative cases too.

Nature of the Association between Rheumatoid Arthritis and Cervical Cancer and Its Potential Therapeutic Implications

It is now established that patients with rheumatoid arthritis (RA) have an increased risk of developing cervical cancer (CC) or its precursor, cervical intraepithelial neoplasia (CIN). However, the underlying mechanisms of this association have not been elucidated. RA is characterized by unresolved chronic inflammation. It is suggested that human papillomavirus (HPV) infection in RA patients exacerbates inflammation, increasing the risk of CC. The tumor microenvironment in RA patients with CC is also marked by chronic inflammation, which aggravates the manifestations of both conditions. Gut and vaginal dysbiosis are also considered potential mechanisms that contribute to the chronic inflammation and aggravation of RA and CC manifestations. Numerous clinical and pre-clinical studies have demonstrated the beneficial effects of various nutritional approaches to attenuate chronic inflammation, including polyunsaturated fatty acids and their derivatives, specialized pro-resolving mediators (SPMs), probiotics, prebiotics, and certain diets. We believe that successful resolution of chronic inflammation and correction of dysbiosis, in combination with current anti-RA and anti-CC therapies, is a promising therapeutic approach for RA and CC. This approach could also reduce the risk of CC development in HPV-infected RA patients.

Prevalence and correlates of Human Papillomavirus infection in females from Southern Province, Zambia: A cross-sectional study

BACKGROUND

Human papillomavirus (HPV) infection is strongly associated with cervical cancer with almost all cases being associated with the infection. Cervical cancer is the leading cause of cancer death among women in Zambia and the fourth leading cause of cancer death in women worldwide. However, there is limited data on the burden and associated factors of HPV in sub-Saharan Africa. This study therefore aimed to determine the prevalence and correlates of HPV infection in the Southern province of Zambia.

METHODS

This was a cross-sectional study conducted at Livingstone University Teaching Hospital (LUTH) among 4,612 women from different districts of the southern province being screened for HPV infection between September 2021 and August 2022. Demographic and clinical data were collected from an existing laboratory programmatic database. Multivariable logistic regression was used to estimate the factors associated with HPV infection.

RESULTS

The study participants had a median age of 39 years [interquartile range (IQR) 30, 47]. The prevalence of HPV infection was 35.56% (95%CI). At multivariable analysis, the factors associated with a positive HPV result were younger age (adjusted odds ratio (AOR) 0.98; 95% confidence interval (CI) 0.98-0.99; p. value 0.001), having provider collected sample (AOR 2.15; 95%CI 1.66-2.79; p. value <0.001) and living with HIV (AOR 1.77; 95%CI 1.22-2.55; p. value <0.002).

CONCLUSION

The prevalence of HPV in women in the southern province of Zambia is high, and likely influenced by age and HIV status. Additionally, the outcome of the HPV test is affected by the sample collection method. Therefore, there is a necessity to enhance HPV and cervical cancer screening, especially among people with HIV.

Questionnaire survey on the prevention and development of cervical cancer in patients with systemic lupus erythematosus in Japan

OBJECTIVES

The aim is to evaluate the prevention and development of cervical cancer in systemic lupus erythematosus (SLE) patients in Japan and its background based on a questionnaire survey.

METHODS

The questionnaire was handed to 460 adult female SLE patients at 12 medical institutions. The participants were grouped by age, and data related to their human papillomavirus vaccination status, age at first coitus, cervical cancer screening, and diagnosis of cervical cancer were analysed.

RESULTS

A total of 320 responses were received. Patients aged 35-54 years included a higher proportion of patients whose age at first coitus was <20 years. This group also showed a higher rate of cervical cancer/dysplasia. Only nine patients had a human papillomavirus vaccination history. Adequate frequency of cervical cancer screening was slightly higher (52.1%) among SLE patients than in the Japanese general population. However, 23% of the patients had never undergone examination, primarily because of a feeling of troublesome. The incidence of cervical cancer was significantly higher among SLE patients. One reason for this may be associated with the use of immunosuppressants, although the difference was not significant.

CONCLUSIONS

SLE patients are at a higher risk of cervical cancer and dysplasia. Rheumatologists should proactively recommend vaccination and screening examinations for SLE female patients.

Canadian Guideline on the Management of a Positive Human Papillomavirus Test and Guidance for Specific Populations

The purpose of this paper is to provide evidence-based guidance on the management of a positive human papilloma virus (HPV) test and to provide guidance around screening and HPV testing for specific patient populations. The guideline was developed by a working group in collaboration with the Gynecologic Oncology Society of Canada (GOC), Society of Colposcopists of Canada (SCC), and the Canadian Partnership Against Cancer. The literature informing these guidelines was obtained through a systematic review of relevant literature by a multi-step search process led by an information specialist. The literature was reviewed up to July 2021 with manual searches of relevant national guidelines and more recent publications. The quality of the evidence and strength of recommendations were developed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework. The intended users of this guideline include primary care providers, gynecologists, colposcopists, screening programs, and healthcare facilities. The implementation of the recommendations will ensure an optimum implementation of HPV testing with a focus on the management of positive results. Recommendations for appropriate care for underserved and marginalized groups are made.

Risk of primary Sjogren's Syndrome following human papillomavirus infections: a nationwide population-based cohort study

Introduction

Viral infection is an exogeneous factor for primary Sjogren's syndrome (pSS). This study investigated the association between human papillomavirus (HPV) infections and pSS through a nationwide population based cohort study.

Methods

Patients with HPV infections between January, 1999 and December, 2013 were included. The incidence of new-onset pSS in patients with HPV infections and non-HPV controls were derived. The multiple Cox regression model derived the risk of pSS in patients with HPV infections. Subgroup analysis and sensitivity analysis were performed to validate the association.

Results

During a follow-up period of 12 years, the adjusted hazard ratio (aHR) of pSS in patients with HPV infections was significantly higher than that in non-HPV controls (aHR=1.64, 95% CI=1.47-1.83, P<0.001). The risk of pSS increased with age and the risk increased by 2.64-fold (95% CI= 2.37-2.93) for those older than 45 years. The significant association between HPV infections and the risk of pSS persisted in the sensitivity analysis restricted in HPV infections that lasted over 12 months (aHR=1.63, 95%CI=1.45-1.83, P<0.0001). Subgroup analyses revealed that both male (aHR=1.83, 95%CI=1.47-2.28, P<0.0001) and female (aHR=1.58, 95%CI=1.40-1.79, P<0.0001) patients with HPV infections and HPV-infected patients aged between 16 and 45 years (aHR=1.60, 95%CI=1.34-1.91, P<0.0001) and over 45 years (aHR=1.67, 95%CI=1.46-1.91, P<0.0001) were associated with a significantly greater risk of pSS.

Conclusion

Patients with HPV infections presented with a significantly higher risk of pSS, regardless of age and sex.

Human Papilloma Virus Vaccination in Patients with Rheumatic Diseases in France: A Study of Vaccination Coverage and Drivers of Vaccination

Objectives: To describe human papillomavirus (HPV) vaccination practices in adolescent girls with systemic lupus erythematosus (SLE) and juvenile idiopathic arthritis (JIA) and to identify barriers to and motivators for vaccination. Methods: Cross-sectional, multicenter study on girls aged 9 to 19 years and their accompanying adults. The measurement criteria were the proportion of girls who were vaccinated against HPV, compliance with the vaccination schedule, factors associated with vaccination, and reasons for vaccination and non-vaccination through a self-administered questionnaire. Results: Seventy-one patients (16 with SLE and 55 with JIA) were included with a mean age of 13 years old (rank 11−18). According to parental questioning, 39% of patients were vaccinated against HPV or in progress (44% and 38% of SLE and JIA, respectively). This rate was 82% for the 22 patients ≥ 15 years of age. The vaccine was administered as often by a general practitioner (39%) as by a hospital pediatrician (also 39%). Two factors were significantly associated with vaccination: Older age (OR 53.68, 95% CI 5.85−429.29, p < 0.001) and previous hepatitis B vaccination (OR 4.97, 95% CI 1.03−24.01, p = 0.040). Recommendation of the vaccine by a health professional and fear of HPV-related diseases were the main facilitators. Lack of knowledge about the vaccine, lack of recommendation by a health professional, and fear of vaccine side effects were the main barriers. Conclusions: HPV vaccination coverage remains insufficient among patients with autoimmune disease. Education and awareness of health professionals about HPV infections are crucial elements in vaccine acceptance.

Development and Validation of a Prognostic Signature Based on Immune Genes in Cervical Cancer

BACKGROUND

Cervical cancer is one of the most common types of gynecological malignancies worldwide. This study aims to develop an immune signature to predict survival in cervical cancer.

METHOD

The gene expression data of 296 patients with cervical cancer from The Cancer Genome Atlas database (TCGA) and immune-related genes from the Immunology Database and Analysis Portal (ImmPort) database were included in this study. The immune signature was developed based on prognostic genes. The validation dataset was downloaded from the Gene Expression Omnibus (GEO) database.

RESULT

The immune signature namely immune-based prognostic score (IPRS) was developed with 229 genes. Multivariate analysis revealed that the IPRS was an independent prognostic factor for overall survival (OS) and progression-free survival (PFS) in patients with cervical cancer. Patients were stratified into high IPRS and low IPRS groups, and those in the high IPRS group were associated with better survival, which was validated in the validation set. A nomogram with IPRS and stage was constructed to predict mortality in cervical cancer.

CONCLUSIONS

We developed a robust prognostic signature IPRS that could be used to predict patients' survival outcome.

Chronic treatment with hydroxychloroquine and SARS-CoV-2 infection

Hydroxychloroquine sulfate (HCQ) is being scrutinized for repositioning in the treatment and prevention of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. This antimalarial drug is also chronically used to treat patients with autoimmune diseases. By analyzing the Portuguese anonymized data on private and public based medical prescriptions we have identified all cases chronically receiving HCQ for the management of diseases, such as systemic lupus erythematosus, rheumatoid arthritis, and other autoimmune diseases. Additionally, we have detected all laboratory confirmed cases of SARS-CoV-2 infection and all laboratory confirmed negative cases in the Portuguese population (mandatorily registered in a centrally managed database). Cross linking the two sets of data has allowed us to compare the proportion of HCQ chronic treatment (at least 2 grams per month) in laboratory confirmed cases of SARS-CoV-2 infection with laboratory confirmed negative cases. Out of 26 815 SARS-CoV-2 positive patients, 77 (0.29%) were chronically treated with HCQ, while 1215 (0.36%) out of 333 489 negative patients were receiving it chronically (P = .04). After adjustment for age, sex, and chronic treatment with corticosteroids and/or immunosuppressants, the odds ratio of SARS-CoV-2 infection for chronic treatment with HCQ has been 0.51 (0.37-0.70). Our data suggest that chronic treatment with HCQ confer protection against SARS-CoV-2 infection.

[Human papillomavirus and systemic lupus erythematosus]

Infection with human papillomavirus (HPV) is one of the most widespread sexually transmitted diseases and the main risk factor for cervical cancer. Underlying conditions, like immunosuppression, favour the persistence and the progression of cervical lesions to an aggressive form. Patients with autoimmune diseases, and particularly systemic lupus erythematosus (SLE), may be prone to HPV infection and cervical dysplasia. However, the risk factors for developing persistent HPV-related infection, dysplasia and cancer are not identified for patients with SLE. The existence of an increased risk of cervical cancer compared to the general population remains debated. Thus, HPV vaccine is recommended for SLE patients as well as for the general population. Vaccine coverage of SLE patients is not known in France. Adolescents with chronic health condition seem to be insufficiently vaccinated regarding their vulnerability to infectious diseases. Strategies are required to decrease HPV vaccination barriers.
