Precancerous lesions of cervix among women infected with HIV in Referral Hospitals of Amhara Region, Northwest Ethiopia: a cross sectional study

Precancerous cervical lesions and associated factors among women on antiretroviral therapy at Dukem Health Center, Central Ethiopia: A cross-sectional study

Background and Aims

Cervical cancer is a global public health problem and the second most common cancer which leads to morbidity and mortality among women in developing countries like Ethiopia. In Ethiopia, annually 6294 new cervical cancer cases and 4884 deaths are estimated in 2018 alone. This study aimed to assess the prevalence and associated factors of precancerous cervical lesions among women on antiretroviral therapy (ART) at Dukem Health Center, Central Ethiopia.

Methods

An institution-based cross-sectional study was carried out among randomly selected 257 women receiving ART at Dukem Health Center. Data were collected using a pretested structured questionnaire, medical record review, and visual inspection with acetic acid. Collected data were entered into Epi-info 7.4 and exported to SPSS version 26 for analysis. The prevalence of precancerous cervical lesions and the characteristics of study participants were identified. Utilizing both binary and multivariable logistic regression models, the existence and degree of association with precancerous cervical lesions were determined with a p value < 0.05 and a 95% confidence interval.

Results

The prevalence of precancerous cervical lesions was 16% (95% CI: 11.7-20.6). Significant association was found between precancerous cervical lesions and a history of STIs (AOR = 4.30, 95% CI: 1.48-12.49), oral contraceptive use (AOR = 6.56, 95% CI: 2.10-20.50), having multiple lifetime sexual partners (AOR = 2.53: 95% CI: 1.05-6.10), and a recent CD4 count of less than 200 cells/mm3 (AOR: 11.33, 95% CI: 2.88-24.58).

Conclusion

In the study area, the prevalence of precancerous cervical lesions was relatively high. Therefore, concerned bodies are recommended to increase awareness of the prevention of sexually transmitted diseases and limit sexual partners.

Cervical Epithelial Abnormalities and Associated Factors among HIV-Infected Women in Lagos, Nigeria: A Cytology-Based Study

INTRODUCTION

As it may not be feasible to provide cervical cancer screening services to all HIV-infected women in most resource-limited settings, there is a need to identify those who are most at risk. We determined the prevalence, patterns, and associated factors of cervical cytological abnormalities among HIV-infected women in Lagos, Nigeria.

METHODS

This descriptive cross-sectional study was conducted among HIV-infected women at the adult HIV treatment and colposcopy clinics of a university teaching hospital in Lagos, Nigeria, between October 2018 and December 2019. A cervical sample was collected from each woman to detect cervical cytological abnormalities.

RESULTS

Of the 593 enrolled women, cervical cytological abnormalities were present in 40 (6.7%). Most (37.5%) of the women with cytological abnormalities had atypical squamous cells of undetermined significance. Age at coitarche (<20 vs. ≥20 years: adjusted odds ratio, 2.42; 95% confidence interval, 1.21-4.83, p = 0.01) was the only factor that was independently associated with cervical epithelial abnormalities.

CONCLUSION

The prevalence of cervical cytological abnormalities in our study is lower than most previous reports in Africa. Sexual debut at an early age was significantly associated with cytological abnormalities. It is necessary to confirm the findings of this study through a well-designed and adequately powered longitudinal study.

Precancerous Lesion of the Cervix and Associated Factors Among Women of West Wollega, West Ethiopia, 2022

Background

Precancerous cervical lesion is an abnormality in the cells of the cervix that could eventually develop into cervical cancer. Cervical cancer is a public health problem that contributes to the death of women worldwide. In line with the high burden of the issue, the Ethiopian government had attempted to expand cervical cancer screening centers and recommendation of services to age-eligible as well as high-risk groups of women. Therefore, the study aimed to assess the prevalence of precancerous lesions of cervix cancer among women aged 30-49 years and associated factors in West Wollega.

Method

Facility-based analytic cross-sectional study design was conducted in selected hospitals of West Wollega from January 1- February 20, 2022, among 339 women. A face-to-face interview was conducted and the presence or absence of precancerous cervical lesion was tested by visual inspection with acetic acid. Data were analyzed by SPSS version 25. Variable with P-value <.25 in the bi-variable analysis were entered into multivariable logistic regression. Results with a P-value ≤ .05 at 95% confidence level were considered for statistical significance.

Result

The prevalence of precancerous cervical lesions was 27.4% (95% CI: 22.7%32.1%). The mean standard deviation of participants was 35.22 +6.32 years. More than half (63.4%) and 67.6% of them were regarded as having good knowledge and a favorable attitude towards precancerous cervical lesions respectively. History of menstrual irregularity had two folds higher odds of being diagnosed with the precancerous cervical lesion when compared with counterparts at, [AOR = 2.29(95% CI:1.29-4.04]. Women with a history of STI had 3.5 times higher odds of developing precancerous cervical lesion compared to women with no history of STI [AOR)=3.46(95% CI:1.94-6.18)], history of bleeding after sexual intercourse was 2.88 times more likely to have precancerous cervical lesion compared to those without it at [AOR=2.88(95% CI:1.43-5.78)]. Parity greater than or equal to five had 2.4 times higher odds of developing precancerous cervical lesions compared to women with parity less than five at [AOR=2.41(95% CI: 1.23-4.75)]. History of steroid use had 3.5 times higher odds of developing precancerous cervical lesion compared with opponents at [AOR=3.5(95% CI: 1.32-9.34) and women with an Unfavorable attitude towards screening for Cervical cancer screening, prevention, and control methods had 2.2 times higher odds of developing precancerous cervical lesion compared their counterpart at [AOR=2.15(95% CI: 1.21-3.83)].

Conclusion

The precancerous cervical lesions continue to be a significant public health concern in Ethiopia. It will remain a significant cause of death of women unless effective screening methods like VIA and vaccination against HPV are scaled up. Furthermore, having a history of menstrual irregularities, STI, bleeding after coitus, parity greater than ≥5, steroid use, and having an unfavorable attitude towards screening factors are significantly associated with the occurrence of the precancerous lesion. Therefore, effective prevention approaches have to consider these factors for the control of cervical cancer in the early phase of the lesion.

Precancerous Lesions of the Cervix and Associated Factors among Women of East Gojjam, Northwest Ethiopia, 2020

BACKGROUND

Cervical cancer is the commonest cancer of women's reproductive system, and is caused by a progression of precancerous lesions of the cervix. Studies on the prevalence and associated factors of precancerous lesions of the cervix are very limited in Ethiopia, particularly in the study area.

OBJECTIVE

This study aimed to assess precancerous lesions of the cervix and associated factors among women of East Gojjam, northwest Ethiopia in 2020.

METHODS

A facility-based cross-sectional study was conducted on 340 cervical cancer-screened women in three hospitals of East Gojjam from February to April 2020. Data were collected by six BSc-qualified nurses who were working in the selected hospitals. EpiData Manager and SPSS 26 were used for data management and analysis. After the data had been clean, descriptive analysis was done and multivariate logistic regression used to identify predictors of precancerous lesions of the cervix. Statistical significance was taken to be P<0.05.

RESULTS

Of the 340 recruited women, 15.3% (95% CI 11.83%-19.54%) had precancerous cervical lesions. Mean age was 37.11±9.3 years. Age 46-55 (AOR 3.8, 95% CI 1.21-12.47) years, age 56-65 (AOR 12.26, 95% CI 3.18-47.18) years, residing rurally (AOR 2.04, 95% CI 1.12-3.7), prolonged use of oral contraceptive pills (AOR 9.11, 95% CI 1.14-72.8), history of sexual transmitted infection (STI; AOR 3.40, 95% CI 1.32-8.78), HIV-positive status (AOR 4.89, 95% CI 1.54-15.49), and number of lifetime sexual partners (AOR 9.87, 95% CI 1.38-70.4) were important factors associated with precancerous lesions of the cervix.

CONCLUSION

We found relatively high prevalence of precancerous cervical lesions. Age, rural residence, prolonged use of oral contraceptives, STI, multiple sexual partners, and being HIV-positive were important factors associated with precancerous cervical lesions. Women aged >46 years, with a history of STI, being HIV infected, and with a history of multiple sexual partners should be encouraged to get screened for cervical cancer.

Precancerous cervical lesion in Ethiopia: systematic review and meta-analysis

BACKGROUND

Though cervical cancer is largely preventable, it is still the second most common female cancer globally and the leading cause of cancer deaths among females in African. Though many efforts have been done to study the burden of the disease in Ethiopia, primary studies examining the prevalence of precancerous cervical lesions are fragmented. Hence, this systematic review and meta-analysis is aimed at estimating the pooled prevalence of precancerous cervical lesion and its trends in Ethiopia.

METHODS

This systematic review and meta-analysis was conducted using the following electronic databases. PubMed, Web of Science, SCOPUS, Science Direct, Google Scholar, African Index Medicus (AIM), African Journals Online databases, and Addis Ababa and Bahir Dar Universities research repositories were searched following the Preferred Items for Systematic Review and Meta-analysis (PRISMA) Guideline. STATA 15 statistical software was used to analyze the data. The quality of the included studies was assessed using the Joanna Briggs Institute (JBI) quality appraisal tool for meta-analysis. Heterogeneity between studies was assessed using the Cochrane Q test and I2 test statistics based on the random effects model. A random effects model was computed to estimate the pooled prevalence of precancerous cervical lesion in Ethiopia. Finally, the trend of precancerous cervical lesion in the country was presented.

RESULT

Seventeen studies with a total of 26,112 participants were included in the analysis. The pooled prevalence of precancerous cervical lesion was 15.16 (95% CI 10.16-19.70). The subgroup analysis by region showed the highest prevalence of precancerous cervical lesion at the Southern Nations and Nationalities Peoples Region (19.65%; 95% CI 15.51-23.80). The trend of precancerous cervical lesion prevalence showed an increased pattern over time.

CONCLUSION

Approximately one among six of the study participants had precancerous cervical lesion. The trend also showed that there is still an increasing precancerous cervical lesion in Ethiopia. Best practices in achieving high vaccination coverage shall be informed by practices in other successful countries.

Precancerous Cervical Lesions Among HIV-Infected Women Attending HIV Care and Treatment Clinics in Southwest Ethiopia: A Cross-Sectional Study

Background

Despite being one of the few cancers that can be prevented with simple testing, cervical cancer is the fourth most common cancer in women. HIV-positive women showed a median three-fold higher incidence of cervical lesions.

Aim

This study aims to assess the prevalence and factors associated with precancerous cervical lesions among HIV-infected women attending care and treatment clinic in selected hospitals of Southwestern Ethiopia.

Methods

Institution-based cross-sectional study was conducted from February 1 to July 30, 2018. A systematic random sampling technique was employed to select 454 HIV-infected women. Pretested interviewer-administered questionnaire and medical record review were used for data collection. Visual inspection with Acetic acid was done for participants to detect precancerous cervical lesions. Data were analyzed by SPSS version 20. Binary and multiple logistic regression analyses were done. The presence and strength of association were determined using AOR with its 95% CI. Variables with a P value of less than 0.05 were considered as statistically significant.

Results

The prevalence of precancerous cervical lesion was 18.7% [95% CI; (15.1–22.4%)]. Currently, not being on highly active antiretroviral treatment [AOR= 2.31, 95% CI: 1.23–4.39], age (20–29 years) [AOR= 0.185, 95% CI: 0.036,0.939], has no history of sexually transmitted infection [AOR=0.026, 95% CI: 0.006–0.116], has no history of genital wart [AOR= 0.261, 95% CI: 0.073–0.934] and having one lifetime sexual partner [AOR=0.133, 95% CI: 0.024–0.726] were found to be significantly associated with precancerous cervical lesion.

Conclusion

The prevalence of Precancerous Cervical lesion was found to be high in this study. Expansion of screening services and undertaking preventive measures against sexually transmitted infection need to be emphasized.

Bioinformatics Analysis of Key Genes and Pathways of Cervical Cancer

Background and Objective

Globally, cervical cancer (CC) is the fourth most common cancer affecting women. Although effective screening reduces its incidence, it remains one of the most serious cancers threatening the health of women. Therefore, the purpose of this study is to find new genes that can be used as potential biomarkers for the prognosis of CC.

Methods and Results

After downloading three datasets such as GSE6791, GSE63678, and GSE63514 from the Gene Expression Omnibus (GEO), we combined the expression matrixes and analyzed them to obtain the differential expressed genes (DEGs). Next, using the STRING website, we performed the protein interaction network analysis. Subsequently, hub genes were screened using the R and Cytoscape software. Then, the expression difference and survival analyses of the hub genes were confirmed using GIPIA. Here, we established that the KNTC1 gene was correlated to the overall survival prognosis of CC. Besides, the expression of the KNTC1 gene in the GSE63514 dataset was significantly different from that of the normal cervix, cervical pre-cancerous lesions, and CC. Consequently, immunohistochemistry analysis showed that the results have a definite diagnostic value.

Conclusion

The KNTC1 gene could be linked with the pathophysiology of CC and maybe one of the early diagnostic markers for the diagnosis of cervical pre-cancerous lesions.

Precancerous lesions of the cervix and its determinants among Ethiopian women: Systematic review and meta-analysis

Introduction

Precancerous lesions of the cervix are changes in cervical cells that make them more likely to develop into cancer. Understanding the prevalence and determinants of the precancerous lesions of the cervix among women helps to take an action like vaccination programs, improving screening coverage, and close management and follow-up which could decrease the morbidity and mortality caused by cervical cancer.

Materials and methods

The international databases, PubMed/MEDLINE, Web of Science, EMBASE, CINAHL, Google Scholar, Science Direct and Cochrane Library and unpublished reports were systematically searched. Two authors independently extracted all necessary data using a standardized data extraction format. STATA 14 statistical software was employed to analyse the data. The Cochrane Q test statistics and I² tests were used to assess the heterogeneity between the studies. A random-effect model was computed to estimate the pooled prevalence of precancerous lesions of the cervix in Ethiopia. Determinants of the precancerous lesion of cervix (early initiation of sexual intercourse, multiple sexual partners, and history of sexually transmitted infection) were analysed.

Results

Thirteen studies fulfilled the inclusion criteria and included in the meta-analysis. The I² test result showed high heterogeneity (I2, 93.2%, p = <0.001). Using the random effect analysis, the pooled prevalence of precancerous lesions of the cervix among women in Ethiopia was 14.21% (95% CI (10.49, 17.94). After adjusting of publication bias using trim-and-fill method, the pooled prevalence was 9.43% (95% CI (5.23, 13.62). Women who had multiple sexual partners in their lifetime (OR:2.67 CI: 1.49,4.79) and had a history of sexually transmitted infections (OR:6.22 CI: 2.99,12.92) were more likely to have a precancerous lesion of the cervix.

Conclusion

The pooled prevalence of the precancerous lesions of the cervix among Ethiopian women was 9.43%. It was associated with having multiple sexual partners and a history of sexually transmitted infections.
