This study aimed to determine the prevalence of HPV infection in women in the Lekoumou and Niari departments of Congo Brazzaville. The researchers collected samples from 100 women aged 16-73 and tested them for HPV. They found an overall HPV prevalence of 29%. Certain demographic factors like age, education level, marital status, age of first intercourse, number of sexual partners and parity did not show statistically significant associations with HPV infection status. The study provides baseline data on HPV prevalence in the region that can inform future cervical cancer prevention efforts.

Genotypes and Associated Risk Levels of Human Papilloma Virus among Female Pa...IIJSRJournal
Background: Human papillomavirus is the main factor in the etiology of cervical cancer, with over 99.7% of cases being associated with high-risk human papillomavirus infection. Although the majority of HPV infections are asymptomatic and self-limiting, persistent HPV infection can result in genital warts, oropharyngeal cancer, and cervical cancer in women, in addition to various anogenital malignancies and other genital warts in both men and women.
Method: This was a cross-sectional descriptive study which employed a convenience sampling technique where both qualitative and quantitative methods were used for data collection. A total of 374 participants were enrolled in the study and a semi structured questionnaire was administered to collect socio-demographic, reproductive and sexual history data. Laboratory analysis involved detection of HPV DNA hybrids with a chemiluminescent substrate, Digene Hybrid Capture 2 technology. Descriptive and inferential (logistic regression) analyses at level of significant (α=0.05) were used to summarize the data, and results illustrated using charts and tables.
Results: The study findings reported a significant risk level of human papillomavirus among female of age group 40-49 years (AOR; 0.15, 95% CI: 0.03-0.79; p = 0.026). Furthermore, in bivariate logistic regression the circulating HPV genotypes among the respondents was significantly characterized among women of the same age group (95% CI; 0.09-0.7; p = 0.008) as well as in the multivariate regression (AOR = 0.13; 95% CI: 0.02-0.72; p = 0.019).
Conclusion: The study thus concluded that there is 23/94 (25.67%) risk of developing cervical cancer due to high risk level HPV (with the presence of low risk level HPV 71/94 (74.33%) known for causing various forms of warts. Therefore, there is need for combined efforts from the Ministry of health and stakeholders to avail and train health care workers on the usage of HPV DNA kits to ensure timely detection of low and high-risk levels HPV. This will ensure timely identification of women at increased risk for the development of cervical cancer, thereby reducing mortality rate.

Malaria parasitaemia and socioeconomic status of selected residents of Emohua...IOSRJPBS
In Nigeria, malaria consistently ranks among the five most common cause of death in children. This study investigated the prevalence of malaria and socioeconomic status of someresidents of Emohua Community, Rivers State, Nigeria.Following ethical clearance which was obtained from the University of Port Harcourt and the parents of the subjects who gave their written consents, blood samples were collected through vein puncture from 200 subjects within the age 0-17years, from July 2014-February 2015. Structured questionnaire were administered to the subjects and parents provided answers for younger children.Thick and Thin films were examined microscopically using oil immersion objective following the standardparasitological method. The thin films were fixed with methanol and all films were stained with 10% Giemsa stain diluted with 7.2 buffer water for 10 minutes. The demographic characteristics of 200 subjects examined in Emohua showed that 120(60%) were females and 60(40%) were males. Sex related prevalence showed that more females were infected with 66(62.3%) and had higher parasite density of 144720/ul than males with 40 (37.7%) and parasite density of 106160/ul though the difference was not significant (P>0.05). Out of the 200 subjects examined, 106(53.0%) were positive for Plasmodium falciparum. Age related prevalence showed that subjects within the age 0-3years and 4-6years had higher prevalence of 62 (31%) followed by those within the age 7-9years with 31(15.5%) and the least with zero prevalence was within the age 16-18 years. Those within the age of 4-6years had higher parasite density of 71680/ul followed by 0-3years of age with parasite density of 63360/ul while those within the age 16-18yrs had none (0). The difference in prevalence of malaria in relation to age was significant (P<0.05).>0.05). Subjects that used treated net were more with 117(58.5%), followed by those that do not use net at all with 54(27%) and those whose nets were untreated with 28(14%). Only 1(0.5%) person believed in the potency of prayer as a preventive measure against malaria while none trusted environmental sanitation. Subjects that are non- net users had higher prevalence of 46(85.2%) and more parasite density of 98080/ul followed by the untreated net users with 22(78.6%) and parasite density of 77280/ul while the least prevalence was recorded among the treated net users with 38(32.5%) and parasite density of 75520/ul. The differences in prevalence of infection in relation to preventive measures was significant (P<0.05).more><0.05).There is need to improve socio-economic status and awareness for total compliance to preventive measures among the subjects so as to reduce the malaria prevalence rate to the desired zero level
Factors Associated with Human Papilloma Virus Vaccine Uptake amongst Girls Ag...PUBLISHERJOURNAL
Human papillomavirus (HPV) infection is a sexually transmitted infection. HPV vaccine since its first licensure in 2006 has proven to be safe, highly immunogenic, and induces strong direct and indirect protection against HPV and its sequelae. The study was designed to determine the socio-demographic, health care, and parental factors associated with human papillomavirus vaccine uptake amongst girls aged 9-14 years. The study was a cross-sectional study employing a simple random sampling method and a total of 364 girls were interviewed following the set criteria using questionnaire data. Data were cleaned, coded, and analyzed using SPSS version 22.0. Findings were presented as frequencies, percentages, odd ratios, and p-values using univariate, bivariate, and multivariate analysis. From the study, statistically significant sociodemographic factors such as age (p=0.0000), schooling status (p=0.0000), level of education (p=0.007442), attitudes towards the HPV vaccine (p=0.005175), Receiving vaccine doses from different vaccination sites (p=0.0000), and Ethnicity (p=0.0000), healthcare factors such as outreaches in communities (p=0.0000), information received (p=0.0000), encouragement from health workers (p=0.0000), availability of vaccines (p=0.0000) and parental factors such as knowledge about HPV vaccine(p=0.001), parental hesitancy (p<0.001), level of education (p=0.0000), social economic status (p=0.001), attitudes towards HPV vaccine, (p=0.0000) and HPV vaccine awareness (p=0.0000) were found statistically associated with HPV vaccine uptake amongst girls aged 9-14 years. From the study findings, the study variables such as sociodemographic, and health-related factors were found to be statistically associated with HPV vaccine uptake amongst girls aged 9-14 years. Therefore, effort should be brought to all levels of intervention so that HPV uptake is taken into consideration if the need for good health among girls needs to be achieved.

Helicobacter Pylori is a bacterium involved in the genesis of precancerous lesions of the stomach. This infection is universally
prevalent but is higher in developing countries. A retrospective
study spread over 3 years (2018-2019-2020) was conducted at the
pathological anatomy laboratory of the Chadli Bendjedid Hospital
in El Tarf, northeast Algeria. All patients were submitted to a fiberscope, and the diagnosis was established by histological examination. The results show that of the 134 patients examined, 100%
were diagnosed with chronic gastritis. The prevalence of H. pylori
infection was 61.94%; 63.86% of women were affected, and the
most susceptible age group was 50-59 years; 36.14% of men were
affected, mainly in the age group 30-39 years. Locally, the fundic antrum area appeared to be the most affected (81.93%) with
moderate chronic atrophic gastritis (78.57%) and silent activity
(94.28%), which favors the development of cancer cells.

Knowledge, Attitude and Practice toward Cervical Cancer and Cervical Cancer S...ijtsrd
BACKGROUND Invasive Cervical Cancer ICC has been identified as the second most common cause of morbidity and mortality compared to other cancers among women in Cameroon. Cervical cancer can be treated e ectively if diagnosed early. Less than half the number of participants presented with good practice.The correlation between participants’ knowledge, attitude and practice showed that there was a significant association which therefore provides sufficient evidence to reject the null hypothesis. The result obtained in this study indicates how useful it will be to establish health education programs to increase women’s awareness and knowledge about cervical cancer.

HPV infection, cervical abnormalities, and cancer in HIV-infected women in Mu...Dr.Samsuddin Khan
Background: HIV-infected women are at a higher risk of cervical intraepithelial neoplasia (CIN) and cancer than women in the general population, partly due to a high prevalence of persistent human papillomavirus (HPV) infection. The aim of the study was to assess the burden of HPV infection, cervical abnormalities, and cervical cancer among a cohort of HIV-infected women as part of a routine screening in an urban overpopulated slum setting in Mumbai, India.
Methods: From May 2010 to October 2010, Médecins Sans Frontières and Tata Memorial Hospital Mumbai offered routine annual Pap smears and HPV DNA testing of women attending an antiretroviral therapy (ART) clinic and a 12-month follow-up. Women with abnormal test results were offered cervical biopsy and treatment, including treatment for sexually transmitted infections (STIs).
Results: Ninety-five women were screened. Median age was 38 years (IQR: 33–41); median nadir CD4-count 143 cells/µL (IQR: 79–270); and median time on ART 23 months (IQR:10–41). HPV DNA was detected in 30/94 women (32%), and 18/94 (19%) showed either low-grade or high-grade squamous intraepithelial lesions (LSIL/HSIL) on Pap smear. Overall, >50% had cervical inflammatory reactions including STIs. Of the 43 women with a cervical biopsy, eight (8.4%) had CIN-1, five (5.3%) CIN-2, and two (2.1%) carcinoma in situ. All but one had HPV DNA detected (risk ratio: 11, 95% confidence interval: 3.3–34). By October 2011, 56 women had completed the 12-month follow-up and had been rescreened. No new cases of HPV infection/LSIL/HSIL were detected.
Conclusion: The high prevalence of HPV infection, STIs, and cervical lesions among women attending an ART clinic demonstrates a need for routine screening. Simple, one-stop screening strategies are needed. The optimal screening interval, especially when resources are limited, needs to be determined.
Anemia is a common condition of cancer patients. This is because cancers cause inflammation that decrease red blood cell production. In addition, many chemotherapies are myelosuppressive, meaning they slow down the production of new blood cells by the bone marrow.

HPV infection, cervical abnormalities, and cancer in HIV-infected women in Mu...Dr.Samsuddin Khan
Background: HIV-infected women are at a higher risk of cervical intraepithelial neoplasia (CIN) and cancer than women in the general population, partly due to a high prevalence of persistent human papillomavirus (HPV) infection. The aim of the study was to assess the burden of HPV infection, cervical abnormalities, and cervical cancer among a cohort of HIV-infected women as part of a routine screening in an urban overpopulated slum setting in Mumbai, India.
Methods: From May 2010 to October 2010, Médecins Sans Frontières and Tata Memorial Hospital Mumbai offered routine annual Pap smears and HPV DNA testing of women attending an antiretroviral therapy (ART) clinic and a 12-month follow-up. Women with abnormal test results were offered cervical biopsy and treatment, including treatment for sexually transmitted infections (STIs).
Results: Ninety-five women were screened. Median age was 38 years (IQR: 33–41); median nadir CD4-count 143 cells/µL (IQR: 79–270); and median time on ART 23 months (IQR:10–41). HPV DNA was detected in 30/94 women (32%), and 18/94 (19%) showed either low-grade or high-grade squamous intraepithelial lesions (LSIL/HSIL) on Pap smear. Overall, >50% had cervical inflammatory reactions including STIs. Of the 43 women with a cervical biopsy, eight (8.4%) had CIN-1, five (5.3%) CIN-2, and two (2.1%) carcinoma in situ. All but one had HPV DNA detected (risk ratio: 11, 95% confidence interval: 3.3–34). By October 2011, 56 women had completed the 12-month follow-up and had been rescreened. No new cases of HPV infection/LSIL/HSIL were detected.
Conclusion: The high prevalence of HPV infection, STIs, and cervical lesions among women attending an ART clinic demonstrates a need for routine screening. Simple, one-stop screening strategies are needed. The optimal screening interval, especially when resources are limited, needs to be determined.
Anemia is a common condition of cancer patients. This is because cancers cause inflammation that decrease red blood cell production. In addition, many chemotherapies are myelosuppressive, meaning they slow down the production of new blood cells by the bone marrow.

Helicobacter Pylori (HP) infection is prevalent among patients with dyspepsia in developing countries with low socioeconomic status. The gold standard investigation is invasive method gastric biopsy through upper GI endoscopy, however non-invasive methods (stool for HP antigen) are not reliable up to the mark also need to wait for two weeks without symptomatic treatment. It is important to have a reliable, cost effective and easily accessible non-invasive marker to diagnose patients with H. pylori infection. Several non-invasive laboratory have been predicted in having the role in diagnosis of H.pylori infection. Therefore, the aim of our study was to determine the diagnostic accuracy of platelet to lymphocyte ratio in predicting H.Pylori infection in patients with dyspepsia.

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

countries, the incidence of cervical cancer continues to decrease,
unlike in developing countries, especially in Africa. sub-Saharan
region where the incidence is increasing exponentially mainly be-
cause of the poor organization of screening and prevention policies
[4]. In Congo, cervical cancer is the second most common cancer
in women in terms of incidence and the second in terms of mor-
tality [5]. Some epidemiological and molecular studies related to
HPV and CCU have been carried out in certain departments of the
country Ebatetou E.A. [6] and Boumba A. [7] showed the direct
involvement of HPV 16, 18, 33 and 31 in the development of pre-
cancerous lesions of the cervix, respectively. In the departments
of Niari and Lékoumou, as well as all the other departments of the
Congo, no studies have been carried out. It is in this context that
we set ourselves the objective of determining the prevalence of
HPV infection in the departments of Lékoumou and Niari.
3. Patients and Methods
We conducted a descriptive and cross-sectional study over a period
of 7 months from January to July 2019 in the departments of Lek-
oumou and Niari. The analyzes were carried out in the Laboratory
of Medical and Morphological Analysis of the General Hospital
of Loandjili (HGL) and the Laboratory of Virology, Microbiology
and Quality / Eco-toxicology and Biodiversity (LVMQ / ETB) of
the Faculty of Sciences and Techniques du Maroc (FSTM). Our
study involved a population of 100 women ranging in age from 16
to 73 years old. All of these women voluntarily benefited from a
cervico-uterine sample. Sexually active patients aged 16 and over
who have given informed consent for adults and parental consent
for minors were included. We did not include patients who had
undergone total hysterectomy as well as those who were menstru-
ating. We carried out a simple random draw to constitute the size
of our sample.
3.1. Sampling method
Each patient was placed in a gynecological position. After placing
a sterile disposable speculum, two samples were taken:
• The first sample was taken using an Ayre spatula from the exo
and endocervix. The collected cells were spread evenly and in a
thin layer on a glass slide, then fixed with a cytological fixative
spray (Spray name). Each blade was numbered.
• The 2nd sample was taken using a cytobrush from the exo and
endocervix. The detachable head of the cytobrush was immersed
in a vial containing a 10% buffered formaldehyde solution. Each
bottle was numbered.
3.2. Storage and transport of samples
After collection at the Sibiti base hospital, Komono and Mayéyé
CSIs, the samples were transported to the Pointe-Noire LGH. Stor-
age was at -20 ° C.
The transport to Morocco was done in dry ice by plane, in the
hold, according to the WHO recommendations for the transport
of biological samples. In Morocco, the samples were immediately
returned to -20 ° C in order to maintain the cold chain.
3.3. Molecular analysis
The molecular analysis took place in 4 steps:
• DNA extraction
• The evaluation of the DNA extract
• The detection of HPV viral DNA
• HPV genotyping
3.4. DNA extraction
The DNA extraction took place in 5 phases
• First phase: sample pretreatment
The cells were collected in a 1.5 mL eppendorf tube, to which were
added 250 μL of phosphate buffered saline (PBS). We carried out
two successive washes with PBS, by centrifugation at 12,000 rpm
for 15 min at 4 ° C.
• Second phase: enzymatic digestion
• Third phase: purification with phenol chloroform
• Fourth phase: precipitation
• Fifth phase: washing and rehydration
3.5. Evaluation of the DNA extract
4-2-1-Qualitative evaluation of the DNA extract by β-globin PCR
All PCR amplifications were done in a GeneAmp ® PCR thermal
cycler
3.6. Detection of HPV viral DNA
4-3-1-Revelation
3.7. HPV genotyping by specific PCR
3-4-1-Analysis of specific PCR products
The variables studied were as follows:
- age,
- marital status,
- the level of education,
- the age of first sexual intercourse,
- the number of sexual partners,
- parity,
-the frequency of HPV infection
Bivariate analysis was done between age, education level, age at
first intercourse, number of sexual partners, marital status and par-
ity.
4. Statistical Analysis
All the results of this study were statistically analyzed from the
Chi-square test or Fisher's exact test using Epi-InfoTM software
version 7.1.1.14, USA (http://www.epiinfo.com). For all tests, the
association between two variables was considered statistically sig-

5. Results
During this study we collected 100 women. The mean age of the
patients was 34.6 ± 11.9 years with ranges ranging from 16 to 73
years. The most represented age groups were that of 20-29 years
(31%) and that of 30-39 years (29%) (Table 1). The most repre-
sented level of education was the college level in 53% of cases
monitoring of the level of primary education in 25% of cases
(Figure 1). Almost ¾ of our study population were married wom-
en (74%). Singles represented only 22% of the study population
(Figure 2). The mean age at first intercourse was 16.4 ± 2.3 with
extremes ranging from 12 to 25 years Almost all of the women
(97%) constituting our study population had had their first sex-
ual intercourse before age 20 (Figure 3). The average number of
sexual partners was 5.3 ± 3.2 with extremes ranging from 1 to 15
partners, 53% of the women had at least 5 sexual partners (Table
2). The mean number of deliveries was 3.6 ± 2.4 with extremes
ranging from 0 to 12 deliveries. 36% of our study population had
between 4 and 7 deliveries (Figure 4). Out of 100 cases of women
studied, HPV viral DNA was identified in 29 cases, for an overall
prevalence of infection of 29%. (Table 3). HPV infection was ob-
served in 58.3% in women aged 50 and over while only 12.5%
of
cases in women under 20 were infected (Figure 5). No difference
significant was observed. p = 0.15; chi2 = 2.073 between the level
of instruction and the infection with HPV (Figure 6). Although
50% of the widows of our population are infected by HPV, we did
not observe a significant difference between the carrying of the
infection and marital status. P = 0.91; chi2 = 0.013. (Figure 7).
There was no association between age at first intercourse and HPV
infection (Figure 8). No significant difference was observed (p =
0.47). Chi2 = 0.522 between the number of sexual partners and
HPV infection in (Figure 9). There was no association between the
distribution of HPV infection by number of deliveries. The differ-
ence was not significant with a p = 0.16. Chi2 = 1.985 (Figure 10).

6. Discussion
6.1. Analysis of the methodology
6.2. Type and period of the study
The descriptive and transversal nature of this study ensures an op-
timal quality of the results, because the collection of information
was contemporaneous with the events described. The homogene-
ity of our study sample allowed us to make a simple analysis of
the results obtained, representative of the general population of
the study area.
6.3. Study population
The selection criteria were established in order to avoid bias in the
interpretation of the results. We performed cervico-uterine smears
(CDU) in women aged 16 years or older. For adolescents aged 16
to 18, informed consent from a parent or guardian was required to
be part of the study, while those over 18 had to consent themselves.
Quite similar criteria were also used by Xavier Castellsagué in
2006 [8], in a study on the detection of the HPV genotype in rural
areas in Mozambique. The mean age of women in our study popu-
lation was lower than that observed in the Louie study population
in 2009 [9] which was estimated to be 33.9 years.
6.4. Sampling strategy
The constitution of the sample consisted in making a simple ran-
dom selection of women from the entire rural area of
the Kouilou
department, representing our sampling territory. The purpose of
this random selection was to obtain a number of cases representa-
tive of the general population, in order to ensure statistical signifi-
cance of the results. In total, we selected 100 cases for our cytolog-
ical and molecular studies of HPVs. Elsewhere, but close to us in
Kinshasa, in the Democratic Republic of Congo (DRC), Ali-Risasi
in 2008 [10] using the same methodology, had recruited 272 cases
to carry out this type of molecular study of HPV identification in
the area. urban.
6.5. Sampling method
Like the other teams, including Ali-Risasi in 2008 [10], we used
liquid phase cervico-uterine smear samples. It consisted of rotating
the cytobrush 3 times for each sample and this allowed us to have a
homogeneous study sample, collected under the same conditions.
The density of the cells obtained was perfect in all the samples,
between 1.8 and 2. Currently, the liquid phase smear with the
marketing of transport and preservation media has improved the
conventional smear. The advantage of the liquid phase smear with
cytobrush sample is that it allows both cytomorphological and mo-
lecular study to be done without having to use a second sample.
6.6. Choice of study methodology
According to Mougin in 2001 [11], epidemiological studies car-
ried out around the world have shown that HPV research should
take place well upstream of screening for dysplastic lesions and
the revelation of cervical cancer. Indeed, the detection of HPV in-
fections makes it possible to better identify populations at risk,
with the aim of carrying out better surveillance, and therefore good
prevention against this scourge. Currently, in the absence of a sero-
logical test, molecular biology techniques remain the only reliable
tools for detecting viral DNA in a biological sample.
The genotyping technique was motivated by the objective and pur-
pose of our study: that of studying the genomic variability of HPV
16 strains in our study population. Despite many existing genotyp-
ing techniques, only sequencing can achieve this goal by studying
mutations directly on a fragment of the sequenced gene. Indeed,
sequencing remains the genotyping technique par excellence today
and is used in several studies around the world,

6.7. Prevalence of HPV infection
In a sample of 100 women, our study found a prevalence of HPV
infection of 29%, of which 18% were HPV type 16 (HPV-HR).
In Africa, the work carried out on the genotyping of HPV strains
has found very high frequencies; indeed, Castellsagué et al [8] in
Mozambique found a prevalence of 36% in 2001 with respective-
ly frequencies for subtypes 16, 18 and 45 of 15%, 13% and 8%,
Didelot-Rousseau et al [12] in Burkina-Faso found frequencies of
HPV infection of 62.7% including 36.4% of high-risk subtypes
(7.8% for HPV 16 and 6.4% for HPV 18) and a meta-analysis pub-
lished by Clifford et al [13] noted a frequency of HPV infections
in sub-Saharan Africa of 25.6% including 68.6% of HR HPV (8%
for HPV 16, 4 % for HPV 18 and 6% for HPV 45) in women with
normal cytology.
In our study, the HPV-HR consisted exclusively of type 16. This
rate remains within the limit of most studies carried out in Africa
on the general population which is 54.6% according to Munoz et
al in 2003 [14] and 52 , 9% according to Didellot-Rousseau et al
in 2006 [12]. In Congo, the only molecular studies on HPV have
been carried out by Boumba [7], he focused on the genotyping
of oncogenic HPV in circulation in Congo-Brazzaville, with the
result of a prevalence of HPV 16 of 62.12% in an urban population
of the city of Pointe-Noire. We note that this prevalence is close
to that which we observed, thus confirming the high prevalence
of HPV 16, a high risk oncogenic virus in the rural population of
Kouilou. We were thus able to conclude that the HPV 16 virus in
these two areas (urban in the study by Boumba , rural in ours) is
present at high rates.
6.8. Analysis of HPV infection and associated risk factors
Several studies have shown that certain factors such as sexual be-
havior, parity, pregnancy, age, marital status, level of education
are the risk factors most involved in the development of precan-
cerous and cancerous lesions of the cervix. uterus. In our study,
the statistical analysis between the majority of these risk factors
(in particular parity, age, marital status and level of education) and
HPV infection (viral DNA positivity) n 'showed no significant dif-
ference. This result, although contrary to most studies around the
world, does not call into question the association between these
risk factors and the carriage of HPV infection. Indeed, these risk
factors are reported in the literature as risk factors associated with
HPV infection and these complications [15]. The non-significance
of certain risk factors in our study could be explained on the one
hand by the fact that certain risk factors require a very large sam-
ple to be significant and on the other hand by the fact that some
of these factors are markers of sexual activity more than cervical
HPV lesions according to Mougin in 2001 [16] and Woodnam in
2001 [17]. Only the age of the first sexual intercourse (less than
20 years) is statistically significant for all the risk factors studied,
these observations have been noted in several studies in the world,
those of Castellsague [8] and Munoz [14] for example.
7. Conclusion
Cervical cancer is a public health problem apart from HPV in-
fection which is the risk factor there are some co-factors such as
parity, age at first intercourse. The prevalence of HPV infection
is relatively high in the Lékoumou and Niari regions. This high
prevalence may justify primary and secondary prevention against
cervical cancer in our resource-constrained setting.
