RESUMO

Breast cancer is the most prevalent cancer among African women, with high mortality rates in Ghana. Nuclear factor kappa B (NF-kB) has been associated with tumor progression in breast cancer. However, its clinical validation is controversial and understudied with no known published data on NF-kB (p65) among breast cancer patients in Ghana and other African countries. This study assessed the prognostic significance of NF-kB(p65) expression and its association with various clinicopathological features in breast cancer patients. 90 formalin-fixed breast cancer tissues and 15 normal breast tissues were used to determine the expression of NF-kB (p65) using immunohistochemistry. We explored the correlation between expression of NF-kB (p65) and clinicopathological features. NF-kB (p65) was expressed in 86.7% of breast cancer tissues. There was a significant relationship between NF-kB (p65) expression and tumor grade, proliferation index (Ki67), and molecular subtype. High NF-kB (p65) expression in tumor grade 3 was about 10 times that of grade 1 (54.2% versus 5.1%), and Ki67 > 20 was 79.7% compared to 20.3% for Ki67 ≤ 20. Patients with triple-negative breast cancer (TNBC) had 49.1% overexpression of NF-kB (p65) compared to 17%, 25.4% and 8.5% for luminal A, luminal B, and HER 2 cases respectively. This study demonstrates that NF-kB (p65) was highly expressed among breast cancer patients at Cape Coast Teaching Hospital, Ghana especially in TNBC. NF-kB (p65) could serve as a biomarker for cancer stage, progression, prognosis, and as a therapeutic target.

RESUMO

BACKGROUND: Cervical cancer remains a disease of significant concern to women's health. The aim of this study was to identify predictors of knowledge of cervical cancer among women living with HIV and those with negative or unknown HIV status at the Cape Coast Teaching Hospital (CCTH). METHODS: This study was based on a larger hospital-based analytical cross-sectional study conducted at the antiretroviral therapy (ART) and gynaecology clinics of the Cape Coast Teaching Hospital in Ghana. Participants were women living with HIV (WLHIV) and women without HIV or whose status was unknown, aged 25 to 65 years, seeking healthcare. Data were collected with a questionnaire and analysed using frequencies, percentages, Chi-square test, binary logistic regression and multivariate analysis. RESULTS: The mean age was 39.5 years (± 9.8) and 47.2 years (± 10.7) for women without or unknown HIV and WLHIV, respectively. HIV-negative/unknown women were mostly nulligravida (76%) and nullipara (69%), while WLHIV mostly had pregnancies (76%) and children (84%) in excess of seven. Knowledge of cervical cancer was statistically significantly associated with HIV status (X2 = 75.65; P-value = 0.001). The odds of having knowledge of cervical cancer for women considered to be negative/unknown for HIV were about three times (AOR = 3.07; 95% CI = 1.47, 6.41) higher than their compatriots with HIV. Women with post-secondary/tertiary (AOR = 4.45; 95% CI = 2.11, 9.35) education had significantly higher odds of having knowledge of cervical cancer than those with no education or those with just primary education. CONCLUSIONS: To improve knowledge of cervical cancer among women, an intentionally structured health education programme is needed, particularly for WLHIV, those with lower levels of education and the unemployed.

RESUMO

INTRODUCTION: In sub-Saharan African (SSA) countries endemic for tuberculosis (TB), previous TB is a significant risk factor for non-tuberculous mycobacterial pulmonary disease (NTM-PD). The deployment of GeneXpert MTB/RIF in pulmonary TB diagnostic work-up regularly identifies symptomatic patients with a positive smear microscopy but negative GeneXpert, indicative of NTM presence. This scoping review outlines recent evidence for NTM-PD diagnosis and management in SSA. OBJECTIVE: The review's objective was to outline the risk factors, available diagnostics, management options and outcomes of NTM-PD in high-burden TB settings in SSA using the population-concept-context framework. DESIGN AND DATA SOURCES: We searched existing literature from PubMed, Web of Science, African Journals Online, Google Scholar and grey literature. Studies published between January 2005 and December 2022 were retained. Data were extracted into Rayyan software and Mendeley and summarised using Excel. RESULTS: We identified 785 potential articles, of which 105 were included in the full-text review, with 7 papers retained. Included articles used international criteria for diagnosing NTM-PD. Multiple papers were excluded due to non-application of the criteria, suggesting challenging application in the SSA setting. Identified risk factors include previous TB, smoking and mining. Most commonly, chest radiography and not CT was used for the radiological diagnosis of PD, which may miss early changes related to NTM-PD. Molecular methods for NTM species identification were employed in research settings, usually at referral centres, but were unavailable for routine care. Most studies did not report a standardised approach to treatment and they were not offered treatment for the specific disease, marking a lack of guidance in treatment decision-making. When treatment was provided, the outcome was often not reported due to the lack of implementation of standardised outcome definitions. CONCLUSIONS: These outlined challenges present a unique opportunity for researchers to undertake further studies in NTM-PD and proffer solutions more applicable to SSA.

RESUMO

BACKGROUND: Different countries in sub-Saharan Africa (SSA) have established guidelines to reduce HIV transmission and improve its management in prisons. This narrative review aimed to examine established literature on HIV care and management among incarcerated persons in SSA to identify successful interventions that could inform improved guidelines, policies, and practices related to the clinical care of this population. METHODS: We searched PubMed, Scopus, Web of Science, Embase, and TRIP Medical Databases in August 2022 for articles published between 1st January 2010 and 30th June 2022. We identified 27 eligible articles based on the Population/Concept/Context framework. RESULTS: HIV screening primarily involved mass campaigns rather than formal prison programmes, with limited implementation of universal testing and treatment. Although a few studies reported on access to antiretrovirals (ARVs), prisoners in urban areas and females had disproportionate access. Barriers identified include poor living conditions, high levels of stigma, and resource constraints. Inter-prison transfers, release from prison, and lack of established programmes hindered follow-up and linkage to care. CONCLUSIONS: The implementation of strategies such as universal testing and treatment, human resource strengthening, financing plans for testing, ARV care, and frequent assessment of risk could improve HIV care and management in prisons in SSA.

RESUMO

OBJECTIVE: We examined the effectiveness of a behavioral intervention in promoting cervical cancer screening among women living with HIV (WLWH) in Ghana. METHODS: A Mixed-methods study was conducted involving 83 WLWH, who were randomly assigned to an intervention group (n = 42) to receive voice-recorded messages based on the 3 R model (Reframing, Reprioritizing, and Reforming) or a control group (n = 41) to receive standard care. The primary outcomes were screening uptake and HPV prevalence. Other outcomes were the acceptability, appropriateness, and feasibility of the intervention. RESULTS: The intervention group had a 100% screening rate, and the control group had a 14.63% screening rate. The prevalent rate of high-risk (hr)-HPV genotypes among the women was 67.5% (95%C.I: 0.56-0.77). Over 48% of the participants had multiple hr-HPV genotypes, 64.29% had HPV16/18/45%, and 73.21% had HPV 31/33/45/52/58. Of the women (89.30%) who screened positive, 60% of them were diagnosed and treated for pre-cancer lesions. The intervention messages were acceptable (encourage proactive behavior), feasible (simple, easy to understand), and appropriate (helpful, informative). Facilitators and barriers to self-sampling were identified. CONCLUSION: Combining the 3 R model with self-sampling increases cervical cancer screening among WLWH. PRACTICE IMPLICATION: Healthcare professionals and policymakers can use this model to increase cervical cancer screening.

RESUMO

BACKGROUND: Diagnosing a life-threatening disease like the human immunodeficiency virus (HIV) can be unbearable to the individual, which has implications for their subsequent care-seeking decision-making. However, an essential element of HIV testing is identifying infected individuals and linking them with adequate care services, thus contributing to the UNAIDS 95-95-95 targets. The attainment of these targets has been particularly challenging for lower and middle-income countries (LMIC). This study explored the psychological reactions to a positive HIV status in a hospital treatment centre to provide insight into mental health interventions' role in improving HIV screening and early antiretroviral therapy (ART) initiation to enhance the quality of life. METHODS: An exploratory qualitative study was investigated among adults who were diagnosed as HIV positive. Participants were purposively recruited from an HIV Treatment Centre. Data were collected with semi-structured interviews that explored the interpretations and psychological reactions to their positive HIV status. Overall, 18 participants were interviewed to reach saturation. Data were transcribed verbatim and analysed thematically to produce findings that address the study's objective. RESULTS: Following analysis of participants' interpretations, understanding and implications of their HIV-positive diagnosis, two major themes emerged: (1) anxiety regarding the impact of the disease on self, family and society was overwhelming. Participants were anxious because of the stigma, fear, worry, shock, and shame they faced. (2) Participants expressed hopelessness and could not see meaning or purpose in life. Suicidal ideation, suicide plans and self-harm characterised hopelessness. CONCLUSIONS: The initial reaction to the diagnosis of HIV in this LMIC context has the potential to impact linkage to care negatively and, thus, the attainment of the global 95-95-95 targets. It is, therefore, essential that mental health and psychological support services are integrated with testing services to manage the initial reactions and support individuals to improve early linkage to care and thus improve overall outcomes for the infected individual and society.

RESUMO

Occult hepatitis B infection (OBI) is a public health problem in Burkina Faso. OBI represents a risk factor for the development of cirrhosis and hepatocellular carcinoma (HCC). OBI could be due to mutant viruses undetectable by HBsAg assays or a strong suppression of viral replication and gene expression under the pression of the host immune system. To investigate the role of killer cell immunoglobulin-like receptor (KIR) gene polymorphisms in patients with OBI in Burkina Faso compared to healthy and chronic hepatitis B subjects. A total of 286 participants was recruited, including 42 cases of OBI, 110 cases of chronic hepatitis B and 134 HBV negative subjects. SSP-PCR was performed to search for the presence of KIR genes. The HBV viral load was determined by qPCR. The frequencies of the activator gene KIR2DS5 (P=0.045) and the pseudogene KIR2DP1 (P<0.001) in patients with OBI were higher than those in patients with chronic hepatitis B. These genes are associated with susceptibility of occult hepatitis B infection. The frequencies of the inhibitory KIR gene KIR2DL3 (P=0.01) of patients with occult hepatitis B were lower than those in chronic hepatitis B patients. This gene KIR2DL3 is associated with protection against occult hepatitis B infection. Also, the frequencies of the inhibitory KIR genes KIR2DL2 (P<0.001), KIR2DL3 (P<0.001) and activators KIR2DS2 (P<0.001) in chronic hepatitis B patients were higher compared to the frequencies of the KIR genes in healthy subjects. These genes KIR2DL3, KIR2DL5 (A, B), KIR3DL3, KIR3DS1, KIR2DL2 and KIR2DS2 are thought to be genes associated with the susceptibility to OBI. The KIR2DS5 and KIR2DP1 genes could be associated with susceptibility to OBI. As for the KIR gene KIR2DL3 could be associated with protection against occult hepatitis B infection.

RESUMO

BACKGROUND: For women living with HIV (WLHIV), the burden of persistent HPV infection, cervical pre-cancerous lesions and cancer have been demonstrated to be higher than among HIV-negative women. As Ghana and other lower-middle-income countries (LMIC) work toward developing national cervical cancer programmes, it is essential that local scientific evidence be provided to guide policy decisions, especially for such special populations. The objective of this study was to determine the distribution of high-risk HPV genotype and related factors among WLHIV and its implication for the prevention of cervical cancer prevention efforts. METHODS: A cross-sectional study was conducted at the Cape Coast Teaching Hospital in Ghana. WLHIV, aged 25-65 years, who met the eligibility criteria were recruited through a simple random sampling method. An interviewer-administered questionnaire was used to gather socio-demographic, behavioural, clinical and other pertinent information. The AmpFire HPV detection system (Atila BioSystem, Mointain View, CA was used to detect 15 high-risk HPV genotypes from self-collected cervico-vaginal samples. The data collected were exported to STATA 16.0 for statistical analysis. RESULTS: In all, 330 study participants, with mean age of 47.2 years (SD ± 10.7), were involved. Most (69.1%, n = 188/272) had HIV viral loads < 1000 copies/ml and 41.2% (n = 136) had ever heard of cervical screening. The overall hr-HPV prevalence was 42.7% (n = 141, 95% CI 37.4-48.1) and the five commonest hr-HPV types among screen positives were HPV59 (50.4%), HPV18 (30.5%), HPV35 (26.2%), HPV58 (17%) and HPV45 (14.9%). Most infected women (60.3%, n = 85) had multiple hr-HPV infections, with about 57.4% (n = 81) having 2-5 h-HPV types, while 2.8% (n = 4) had more than five hr-HPV types. A total of 37.6% (n = 53) had HPV16 and/or18, while 66.0% (n = 93) had the hr-HPV genotypes covered by the nonavalent vaccine. Women with HIV viral load ≥ 1000copies/ml (AOR = 5.58, 95% CI 2.89-10.78, p < 0.001) had a higher likelihood of being co-infected. CONCLUSION: This study found out that the prevalence of hr-HPV still remains high in women with HIV, with a notable occurrence of multiple infections and infection with genotypes 16 and/or18. Additionally, an association was established between hr-HPV and infection HIV viral load.. Therefore, comprehensive HIV care for these women should include awareness of cervical cancer, consideration of vaccination and implementation of screening and follow-up protocols. National programmes in LMIC, such as Ghana, should consider using HPV-based screen-triage-treat approach with partial genotyping.

RESUMO

BACKGROUND: Hepatitis B Virus (HBV) infection affect all social strata of humanity and in the absence of any management, this infection has a different outcome from one infected person to another. This suggests that there are specific individual factors that influence the outcome of the pathology. Sex, immunogenetics and age of contraction of the virus have been cited as factors that influence the evolution of the pathology. In this study, we looked at two alleles of the Human Leucocyte Antigen (HLA) system to measure their possible involvement in the evolution of HBV infection. METHOD AND RESULTS: We conducted a cohort study involving 144 individuals spread over 04 distinct stages of infection and then compared allelic frequencies in these populations. A multiplex PCR was conducted and the data obtained was analyzed using R and SPSS software. Our study revealed a predominance of HLA-DRB1*12 in our study population without, however, showing a significant difference between HLA-DRB1*11 and HLA-DRB1*12. The HLA-DRB1*12 proportion was significantly higher in chronic hepatitis B (CHB) and resolved hepatitis B (RHB) compared to cirrhosis and hepatocellular carcinoma (HCC) (p-value = 0,002). Carrying HLA-DRB1*12 has been associated with a low risk of complication of infection (CHB → cirrhosis; OR 0,33 p-value 0,017; RHB → HCC OR 0,13; p-value = 0,00,045) whereas the presence of HLA-DRB1*11 in the absence of HLA-DRB1*12 increased the risk of developing severe liver disease. However, a strong interaction of these alleles with the environment could modulate the infection. CONCLUSION: Our study shown that HLA-DRB1*12 is the most frequent and it's carriage may be protective in the development of infection.

RESUMO

BACKGROUND: Sub-Saharan Africa (SSA) has the highest cervical cancer (CC) burden globally-worsened by its HIV epidemics. In 2020, the World Health Organization (WHO) introduced a CC elimination strategy with goals for vaccination, screening, and treatment. To benchmark progress, we examined temporal trends in screening coverage, percent screened at least twice by the age of 45, screening coverage among women living with HIV (WLHIV), and pre-cancer treatment coverage in SSA. METHODS AND FINDINGS: We conducted a systematic analysis of cross-sectional population-based surveys. It included 52 surveys from 28 countries (2000 to 2020) with information on CC screening among women aged 25 to 49 years (N = 151,338 women). We estimated lifetime and past 3-year screening coverage by age, year, country, and HIV serostatus using a Bayesian multilevel model. Post-stratification and imputations were done to obtain aggregate national, regional, and SSA-level estimates. To measure re-screening by age 45, a life table model was developed. Finally, self-reported pre-cancer treatment coverage was pooled across surveys using a Bayesian meta-analysis. Overall, an estimated 14% (95% credible intervals [95% CrI]: 11% to 21%) of women aged 30 to 49 years had ever been screened for CC in 2020, with important regional and country-level differences. In Eastern and Western/Central Africa, regional screening coverages remained constant from 2000 to 2020 and WLHIV had greater odds of being screened compared to women without HIV. In Southern Africa, however, screening coverages increased and WLHIV had equal odds of screening. Notably this region was found to have higher screening coverage in comparison to other African regions. Rescreening rates were high among women who have already been screened; however, it was estimated that only 12% (95% CrI: 10% to 18%) of women had been screened twice or more by age 45 in 2020. Finally, treatment coverage among 4 countries with data was 84% (95% CrI: 70% to 95%). Limitations of our analyses include the paucity of data on screening modality and the few countries that had multiple surveys. CONCLUSION: Overall, CC screening coverage remains sub-optimal and did not improve much over the last 2 decades, outside of Southern Africa. Action is needed to increase screening coverage if CC elimination is to be achieved.

RESUMO

Background: The objective of this study is to search for mutations in the BRCA1 (c.5177_5180delGAAA and c.4986+6T>C) and BRCA2 genes (c.6445_6446delAT) in a population of women diagnosed with breast cancer. Methods: This is a case-control study that involved 140 participants, including 70 patients with histologically diagnosed breast cancer and 70 healthy women without breast cancer. Mutations in the BRCA1 (rs80357867, rs80358086) and BRCA2 (rs80359592) genes were tested by real-time PCR. The 95% confidence interval Odds Ratio (OR) was used to estimate the associations between specific genotypes and breast cancer. Results: The study revealed that no mutations were detected for rs80359592. Similarly, no reference allele (TTTC/TTTC) of rs80357867 was found in this study. However, the homozygous double mutant (-/) genotype of this rs80357867 was observed in 11.43% and 1.43% of patients and controls respectively, while 88.57% of patients and 98.57% of controls had a heterozygous deletion (TTTC/-). Concerning rs80358086, 8.57% of the patients had a heterozygous mutation (A/G) with no significantly risk association with occurrence of breast cancer (OR = 6.46; 95% CI: 0.75-55.21; p = 0.11). In addition, this heterozygous mutation was significantly associated with a family history of breast cancer (OR=128; 95% CI: 9.46-1730.93) and breast cancer risk in nonmultiparous women (OR=6; 95% CI: 1-35.90; p= 0.05) but no association with overweight/obesity (OR=1.66; 95% CI: 0.18-15.35; p=1). Conclusion: This study shows high frequencies of heterozygous mutation of rs80357867 and rs80358086 from patients. In Burkina Faso, these results could help with early diagnosis of breast cancer in patients.

RESUMO

INTRODUCTION: Self-sampling has the potential to increase cervical cancer (CC) screening among women with HIV in low- and middle-income countries (LMICs). However, our understanding of how HPV self-collection studies have been conducted in women with HIV is limited. The purpose of this scoping review was to examine the extent to which the HPV self-sampling has been applied among women with HIV in LMICs. METHOD: We conducted multiple searches in several databases for articles published between 2000 and January 2022. With the combination of keywords relating to HPV self-sampling, LMICs, and women with HIV, we retrieved over 9000 articles. We used pre-defined inclusion and exclusion criteria to select relevant studies for this review. Once a study met the inclusion criteria, we created a table to extract each study's characteristics and classified them under common themes. We used a qualitative descriptive approach to summarize the scoping results. RESULTS: A total of 12 articles were included in the final review. Overall, 3178 women were enrolled in those studies and 2105 (66%) of them were women with HIV. The self-sampling participation rate was 92.6%. The findings of our study show that 43% of the women with HIV in 8 of the studies reviewed tested positive for high-risk HPV (hr-HPV) genotypes, indicating 4 out of 10 women with HIV in the studies are at risk of cervical cancer. The prevalence of the hr-HPV in women with HIV was 18% higher than that of HIV-negative women. Most women in the study found the self-sampling experience acceptable, easy to use, convenient, and comfortable. Self-sampling performance in detecting hr-HPV genotypes is comparable to clinician-performed sampling. However, limited access (i.e., affordability, availability, transportation), limited knowledge about self-screening, doubts about the credibility of self-sampling results, and stigma remain barriers to the wide acceptance and implementation of self-sampling. In conclusion, the findings of this review highlight that (a) the prevalence of hr-HPV is higher among women with HIV than HIV-negative women, (b) self-sampling laboratory performance is similar to clinician-performed sampling, (c) the majority of the women participated in self-sampling, which could likely increase the cervical cancer screening uptake, and (d) women with HIV reported a positive experience with self-sampling. However, personal, environmental, and structural barriers challenge the application of self-sampling in LMICs, and these need to be addressed.

RESUMO

Introduction: Human herpesvirus type 8 (HHV-8) is the main etiological agent of Kaposi's sarcoma. This virus is frequently associated with immunocompromision. This study aimed to detect HHV-8 in people with compromised immune system. Patients and Methods: This is a cross-sectional study that included 180 subjects: 179 HIV-infected patients and 1 patient with bullous pemphigoid. Blood samples were taken from all subjects, and swabs of lesions were then taken from individuals with symptoms of Kaposi's sarcoma. Viral load and CD4+ T lymphocytes count were performed for persons living with HIV and real-time PCR detection of HHV-8 DNA was performed in all subjects in the study. Results: Among HIV-infected persons, 13.41% had a viral load of more than 10,000 copies/mL, and 22.91% had a CD4+ T lymphocytes count of fewer than 350 cells/µL. A total of four (three HIV-1 infected patients and one patient with bullous pemphigoid) patients (2.22%) had apparent lesions of Kaposi's sarcoma. In the plasmas and swabs from associated lesions, HHV-8 DNA was found in only two individuals, with an HHV-8 prevalence of 1.11% (2/180) with 0.55% (1/179) in an HIV-infected patient on antiretroviral therapy. Conclusion: These results exposing low prevalence levels of HHV-8 in HIV-infected patients could be due to the beneficial effect of antiretroviral drugs.

RESUMO

BACKGROUND: The World Health Organisation's efforts to eliminate cervical cancer by 2030 with a target of 70% screening coverage using a high-performance test demand that women increase participation in screening. Factors that impact uptake of screening must therefore be identified and bottlenecks addressed, especially in lower- and middle-income countries where cervical cancer incidence remains high. This study investigated Muslim women, participation in, intention to engage in and self-efficacy about cervical cancer screening. METHODS: An analytical cross-sectional study was conducted among Muslim women aged 18 years and above in the Cape Coast Metropolis of Ghana using an interviewer-administered questionnaire. Data were analysed using appropriate descriptive statistics, Chi-square test, point biserial correlation and binary logistic regression analysis. RESULTS: The mean age of participants was approximately 31 years (M = 30.9, SD = 10.4). Out of the 431 women, 21 (4.9%) had ever participated in cervical cancer screening. Participants demonstrated very low knowledge about cervical cancer and screening, with a mean knowledge score of 3.68 out of 15. Knowledge about cervical cancer was associated with increased odds of participating in cervical cancer screening (aOR = 1.32, 95%CI 1.11, 1.56). Concerns about similarity with health provider in terms of gender and faith was associated with decreased odds of cervical cancer screening self-efficacy (aOR = 0.81, 95% CI 0.67). Islamic modesty (aOR = 0.88, 95%CI 0.81, 0.96) was associated with decreased self-efficacy about seeking cervical cancer screening, whereas attitude (aOR = 1.32, 95%CI 1.14, 1.53) was significantly associated with increased self-efficacy about seeking cervical cancer screening. Again, Islamic modesty (aOR = 0.88, 95%CI 0.80, 0.97) was associated with decreased intention to participate in screening, whereas attitude (aOR = 1.42, 95%CI 1.20, 1.68) was associated with increased intention to participate in screening. CONCLUSIONS: There are gaps in knowledge of cervical cancer among Muslim women in this study as less than 5% had participated in screening. A positive attitude was found to influence intention to screen and actual participation in screening programmes. Islamic modesty and commitment to the Islamic faith decreased intention and self-efficacy regarding screening. Therefore, comprehensive and appropriate socio-cultural and religion-specific interventions aimed at addressing the barriers to screening are important in improving uptake among Muslim women.

RESUMO

Breast cancer is the leading cause of death among women in both developed and developing countries. It is multifactorial, including genetic predispositions such as oncogenic mutations on BRCA1 and 2 genes. The objectives of the present study were to identify oncogenic mutations in exon 11 of the BRCA1 gene and to determine the risk factors for breast cancer among women population in Burkina Faso. This study involved 100 women, including 50 cases of breast cancer and 50 controls (no clinical signs and no family history of breast cancer or other cancers). Mutations in the BRCA1 gene were detected by PCR using sequence primers specific for exon 11 fragments (11.1 and 11.2). In our study population, age (OR=22.40; CI: 4.33-115.82; p<0.001) and obesity (OR=4.23; CI: 1.64-10.92; p=0.003) were risk factors while multiparity was a protective factor for breast cancer (OR=0.35; CI: 0.15-0.81; p=0.02). A mutation was found on both fragments 11.1 and 11.2 of the BRCA1 gene exon 11 in 04/50 (8.0 %) of patients. No mutations were observed in controls. The present study revealed high frequency of oncogenic mutations in exon 11 fragments (11.1 and 11.2) of the BRCA1 gene. These mutations on exon 11 are and involved in the occurrence of breast cancer in our population. Age and obesity were also risk factors for breast cancer among women population in Burkina Faso.

RESUMO

INTRODUCTION: Hepatitis C virus (HCV) infection remains a major public health problem worldwide. In Burkina Faso, nearly 720,000 people are living with HCV, and each year about 900 people die from complications of cirrhosis or hepatocellular carcinoma. This study was planned to determine the HCV seroprevalence, characterize circulating genotypes, and monitor HCV viral loads in patients under treatment with antivirals. METHODS: A total of 4,124 individuals and 167 patients in the pre-therapy program were recruited. The "SD Bioline HCV" kit was used for rapid screening of anti-HCV antibodies. Viral load and genotyping were performed in 167 HCV patients on antivirals using the "Iontek HCV Quant" and "Iontek genotyping" kits. RESULTS: Prevalence of HCV was 1.65% (68/4,124), and the median viral load of participants was 5.37 log10/mL (1.32-7.67 log10/mL). Genotype 2 was predominant with a frequency of 86.23% (144/167) and appeared to be more active with higher viral load compared to 13.77% (23/167) for genotype 1 (p < 0.001). After 24 weeks of pan-genotypic direct-acting antivirals, such as sofosbuvir/daclatasvir and sofosbuvir/velpatasvir, the viral loads of all patients became undetectable. CONCLUSION: The responses to antivirals by the circulating genotypes indicate that the results are very satisfactory. Therefore, the prevalence of HCV in the population can be reduced through identification of cases and treatment.

RESUMO

INTRODUCTION: Genital human papillomavirus (HPV) infection is widespread among sexually active individuals. Several factors may contribute to increased risk of infection in pregnant women. The objective of this study was to determine the high-risk (HR-HPV) and low-risk (LR-HPV) oncogenic HPV genotypes among pregnant women in Ouagadougou. METHODOLOGY: In this study, 100 endocervical samples were collected using a sterile swab on the sterile examination glove used during vaginal examination in pregnant women. DNA from each sample was amplified by PCR followed by hybridization using the HPV Direct Flow Chips kit detecting 36 HPV genotypes. RESULTS: Twenty-three percent (23%) of pregnant women had HPV infection. Of the 36 genotypes tested, 29 genotypes had been identified with a predominance of HPV 52 (10.34%), HPV 35 (6.89%), and HPV 82 (6.89%) for high risk and HPV 43 (10.34%), HPV 44/55 (6.90%), and HPV 62/81 (6.89%) for low risk. CONCLUSION: HPV is common among pregnant women in Burkina Faso. However, the available vaccines do not cover the frequent genotypes found in this study. HPV could therefore constitute a threat for pregnant women and a risk of infection for the newborn.

RESUMO

BACKGROUND: Nigeria has a high burden of hepatitis B virus (HBV) infection, commonly acquired through vertical transmission. However, there is a lack of an efficient surveillance system for monitoring and understanding the epidemiology of HBV among pregnant women. Building on a previous review on the prevalence of HBV in Nigeria (2000-2013), we conducted a systematic review and meta-analysis of HBV prevalence among pregnant women in Nigeria. METHODS: Four electronic databases PubMed, Embase, Global Health, and Scopus were systematically searched from January 2014 to February 2021. We also searched the African Journal Online and manually scanned the reference lists of the identified studies for potentially eligible articles. Observational studies that reported the prevalence of HBsAg and/or HBeAg among pregnant women in peer-reviewed journals were included in the study. We performed a meta-analysis using a random-effects model. We defined HBV infection as a positive test to HBsAg. RESULTS: From the 158 studies identified, 20 studies with a total sample size of 26, 548 were included in the meta-analysis. The pooled prevalence of HBV infection among pregnant women across the studies was 6.49% (95% confidence interval [CI] = 4.75-8.46%; I2 = 96.7%, p = 0.001; n = 20). The prevalence of HBV was significantly lower among pregnant women with at least secondary education compared with those with no education or primary education (prevalence ratio = 0.7, 95% CI = 0.58-0.87; n = 10). However, the prevalence of HBV was not significantly different by age, religion, marital status, or tribe. The prevalence of HBV was not significantly different among pregnant women with previous surgery, blood transfusion, multiple lifetime sex partners, tribal marks, tattoos, scarification, or sexually transmitted infections, compared with those without these risk factors. From a total sample size of 128 (n = 7), the pooled prevalence of HBeAg among HBV-infected pregnant women was 14.59% (95% CI = 4.58-27.99%; I2 = 65.5%, p = 0.01). Subgroup analyses of HBV infection by study region and screening method, and meta-regression analysis of the study year, sample size, and quality rating were not statistically significant. CONCLUSIONS: There is an intermediate endemicity of HBV infection among pregnant women in Nigeria. Interventions, such as routine antenatal HBV screening, antiviral prophylaxis for eligible pregnant women, and infant HBV vaccination should be scaled up for the prevention of perinatal transmission of HBV infection in Nigeria.

RESUMO

Viral and bacterial infections represent an occupational risk for female sex workers. This study aimed at determining HPV coinfection with genital pathogens among female sex workers in West and Central Africa and identifying antibiotic resistance genes. A total of 182 samples from female sex workers were analyzed by real-time PCR and classic PCR. For the molecular diagnosis of HPV, the real-time multiplex amplification kit "HPV Genotypes 14 Real-TM Quant" from SACACE Biotechnologies®, detecting 14 high-risk HPV genotypes, was used, while for other pathogens, the real-time multiplex amplification kit N. gonorrhoeae/C. trachomatis/M. genitalium/T. vaginalis Real-TM, allowing their simultaneous detection, was used. The women were aged 17-50 years with an average age of 27.12 ± 6.09 years. The pathogens identified were HPV 54.94% (100/120), Neisseria gonorrhoeae (13.74%), Chlamydia trachomatis (11.54%) and Mycoplasma genitalium (11.54%). The most common HPV genotypes were HPV68, HPV38 and HPV52. The antibiotic resistance genes identified were bla QNR B 24.00%, bla GES 22.00%, bla SHV 17.00%, blaCTX-M 13.00% and bla QNR S 1.00%. This study revealed the presence of various HPV genotypes associated with other pathogens with problems of antibiotic resistance among sex workers of West and Central African origin working in Ouagadougou.
