ABSTRACT

INTRODUCTION: The rates of cervical cancer screening in Cameroon are unknown and HPV vaccination coverage for age-appropriate youths is reported at 5%. OBJECTIVES: To implement the mother-child approach to cervical cancer prevention (cervical screening by HPV testing for mothers and HPV vaccination for daughters) in Meskine, Far North, Cameroon. METHODS: After the sensitization of the Meskine-Maroua region using education and a press-release by the Minister of Public Health, a 5-day mother-child campaign took place at Meskine Baptist Hospital. The Ampfire HPV Testing was free for 500 women and vaccination was free for age-appropriate children through the EPI program. Nurses trained in cervical cancer education conducted group teaching sessions prior to having each woman retrieve a personal sample. Self-collected samples were analyzed for HPV the same day. All women with positive tests were assessed using VIA-VILI and treated as appropriate for precancers. RESULTS: 505 women were screened, and 92 children vaccinated (34 boys and 58 girls). Of those screened, 401 (79.4%) were aged 30-49 years old; 415 (82%) married; 348 (69%) no education. Of the HPV positive cases (101): 9 (5.9%) were HPV 16, 11 (10.1%) HPV 18, 74 (73%) HPV of 13 other types. Those who were both HPV and VIA-VILI positive were treated by thermal ablation (63%) or LEEP (25%). CONCLUSION: The mother-child approach is an excellent method to maximize primary and secondary prevention against cervical cancer.

ABSTRACT

Importance: Although Africa has the highest burden of cervical cancer in the world, educational resources to achieve the 90-70-90 targets set by the World Health Organization in its strategy to eliminate cervical cancer are lacking in the region. Objectives: To adapt, implement, and evaluate the Project Extension for Community Health Care Outcomes (ECHO), an innovative learning tool, to build capacity of clinicians to better incorporate new evidence-based guidelines into cervical cancer control policies and clinical practices. Design, Setting, and Participants: This cross-sectional study assessed knowledge and practices of clinicians and support staff regarding cervical cancer prevention and control and compared them among respondents who had attended Project ECHO sessions (prior ECHO attendees) with those who had not but were planning on attending in the near future (newcomers) as part of the Cameroon Cervical Cancer Prevention Project ECHO. Satisfaction of prior ECHO attendees was also evaluated. Data were analyzed from January to March 2022. Main Outcomes and Measures: Main outcomes were practices and knowledge regarding cervical cancer education and prevention and preinvasive management procedures compared among prior ECHO attendees and newcomers. Results: Of the 75 participants (mean [SD] age, 36.4 [10.0] years; 65.7% [95% CI, 54.3%-77.1%] women) enrolled in this study, 41 (54.7%; 95% CI, 43.1%-66.2%) were prior ECHO attendees, and most were clinicians (55 respondents [78.6%; 95% CI, 68.7%-88.4%]). Overall, 50% (95% CI, 37.8%-62.2%) of respondents reported performing cervical cancer screening with visual inspection of the cervix after application of acetic acid (VIA) and/or visual inspection of the cervix after application of Lugol's iodine (VILI), 46.3% (95% CI, 34.0%-58.5%) of respondents reported performing human papillomavirus (HPV) testing, and 30.3% (95% CI, 18.9%-41.7%) of respondents reported performing cervical cytological examination in their practices, Approximately one-fourth of respondents reported performing cryotherapy (25.4% [95% CI, 14.7%-36.1%]), thermal ablation (27.3% [95% CI, 16.2%-38.3%]) or loop electrosurgical excisional procedure (LEEP, 25.0% [95% CI, 14.4%-35.6%]) for treatment of preinvasive disease. The clinical use of many of these screening and treatment tools was significantly higher among prior ECHO attendees compared with newcomers (VIA/VILI: 63.2% [95% CI, 47.4%-78.9%] vs 33.3% [95% CI, 16.0%-50.6%]; P = .03; cryotherapy: 40.5% [95% CI, 24.3%-56.8%] vs 6.7% [95% CI, 0.0%-15.8%]; P = .002; thermal ablation: 43.2% [95% CI, 26.9%-59.6%] vs 6.9% [95% CI, 0.0%-16.4%]; P = .002). Knowledge about cervical cancer education, prevention, and management procedures was satisfactory in 36.1% (95% CI, 23.7%-48.5%) of respondents; this proportion was significantly higher among prior ECHO attendees (53.8% [95% CI, 37.7%-69.9%]) compared with newcomers (4.5% [95% CI, 0.0%-13.5%]; P < .001). Approximately two-thirds of participants (68.8% [95% CI, 51.8%-85.8%]) reported that they had applied knowledge learned in our ECHO sessions to patient care in their practice or adopted best-practice care through their participation in this ECHO program. Conclusions and Relevance: These findings suggest that the Project ECHO e-learning and telementoring program was associated with improved skills for clinicians and support staff and enhanced quality of care for patients. In the COVID-19 era and beyond, reinforced efforts to strengthen cervical cancer knowledge and best practices through distance learning and collaboration are needed.

ABSTRACT

We investigated whether HIV-positive women differ from HIV-negative women in their fertility, fertility intentions, and use of family planning (FP) among 16,202 women who received services through the Cameroon Baptist Convention Health Services' Women's Health Program from 2015 to 2017. The 13% of women who were HIV-positive had similar rates of modern FP usage and unmet need compared to HIV-negative women (26% versus 29% for modern FP usage, and 20% versus 21% for unmet need). However, HIV-positive women were more likely to be satisfied with their FP method (aOR = 1.70, p < .001). There were no significant differences in usage by HIV status for most FP methods, but HIV-positive women were more likely to use condoms (aOR = 1.85, p < .01) and less likely to use IUDs (aOR = 0.77, p < .05). HIV-positive women had fewer living children and also desired fewer children (both associations significant at p < .001 in multivariate linear regression). These findings highlight low FP usage and high unmet need among all women, and the need for integrated HIV and FP services for HIV-positive women, particularly aimed at increasing use of more reliable FP methods in addition to condoms.

ABSTRACT

To achieve higher coverage and effectiveness in limited-resource settings, World Health Organization (WHO) guidelines for cervical cancer prevention recommend a screen-and-treat strategy with high-risk human papillomavirus (HPV) testing. We piloted a real-word project to examine the feasibility of this approach in rural Cameroon. Nurses from the Women's Health Program (WHP) of the Cameroon Baptist Convention Health Services (CBCHS) educated women in remote villages on cervical cancer prevention. At a follow-up visit, they explained to nonpregnant women aged 30-65 how to self-collect vaginal specimens for HPV testing with the careHPV assay. The cytobrush specimens were transported in coolers to a CBCHS laboratory for analysis. The nurses returned to villages to inform women of their results, examined HPV-positive women in the primary health centers (PHCs) using visual inspection with acetic acid and Lugol's iodine (VIA/VILI) enhanced by digital cervicography (DC) to guide treatment. Of the 1,270 eligible women screened (mean age: 44.7 years), 196 (15.4%) were HPV-positive, of whom 185 (94.4%) were examined, 16 (8.6%) were VIA/VILI-positive, 8 (4.3%) were VIA/VILI-inadequate, one (0.5%) was VIA/VILI-uncertain and 161 (87.0%) were treated with thermal ablation. One woman had LEEP, and another woman with invasive cancer was treated at a referral facility. The cytobrushes broke off in the vaginas of two women (removed in the village) and in the bladder of another (surgically removed). Community-based cervical cancer screening with self-collected specimens for HPV testing is feasible in rural Cameroon. Education on the proper sampling procedure and follow-up of women who are HPV-positive are essential.

ABSTRACT

OBJECTIVE: To evaluate group B streptococcus (GBS) colonization prevalence and feasibility of intrapartum GBS screening/antibiotic prophylaxis (IAP) in Cameroon, Africa. METHODS: Prospective cohort in the Cameroon Baptist Convention Health Services network. Maternity providers collected anogenital swabs from consenting term women in labor for testing by a rapid GBS-polymerase chain reaction (PCR) system. Positive tests (GBS+) resulted in initiation of intravenous ampicillin until delivery. Primary outcomes were GBS prevalence and proportion of GBS+ women receiving ampicillin before delivery and more than 4 hours before delivery. RESULTS: A total of 219 women were enrolled from January 10 to April 27, 2017. GBS prevalence was 12.3% (95% confidence interval [CI] 7.9-16.7) with GBS+ women more likely to reside in urban areas (19.6% vs 9.7%, P=0.004). Of 27 GBS+ women, 19 (70.4%) received ampicillin before delivery and 14 (51.9%) 4 hours or longer before delivery. A median two doses of ampicillin (interquartile range [IQR] 1-5) were given and started at a median of 105 minutes (IQR 90-155) after swab collection and 20 minutes (IQR 10-45) after GBS result. Of the 8 women who did not receive ampicillin, 7 (87.5%) delivered before test results. CONCLUSION: A GBS IAP protocol is feasible in Cameroon and should be evaluated for widespread implementation in Cameroon and other low-income countries to decrease GBS-related morbidity.

ABSTRACT

OBJECTIVE: We examined patterns of contraceptive utilization by HIV status among women in Cameroon, hypothesizing that women living with HIV would utilize contraception at higher rates than their HIV-negative peers. METHODS: Deidentified, clinical data from the Cameroon Baptist Convention Health Services (2007-2013) were analyzed (N = 8995). Frequencies compared outcomes between women living with HIV (15.1%) and uninfected women. Multivariate analyses examined associates of contraceptive utilization and desire to become pregnant. RESULTS: Contraceptive utilization was associated with higher education, living with HIV, monogamy, and higher parity ( P < .001). Women living with HIV had 66% higher odds of using contraceptives than their negative peers (odds ratio [OR]: 1.66, confidence interval [CI]: 1.45-1.91, P < .001). Polygamous women had 37% lower odds of using contraceptives compared to monogamous women (OR: 0.63, 95% CI: 0.52-0.75, P < .001). CONCLUSION: Increasing contraceptive utilization in resource-constrained settings should be a priority for clinicians and researchers. Doing so could improve population health by reducing HIV transmission between partners and from mother to child.

ABSTRACT

OBJECTIVE: The World Health Organization (WHO)'s cervical cancer screening guidelines for limited-resource settings recommend sequential screening followed by same-day treatment under a "screen-and-treat" approach. We aimed to (1) assess feasibility and clinical outcomes of screening HIV-positive and HIV-negative Cameroonian women by pairing visual inspection with acetic acid and Lugol's iodine enhanced by digital cervicography (VIA/VILI-DC) with careHPV, a high-risk human papillomavirus (HR-HPV) nucleic acid test designed for low-resource settings; and (2) determine persistence of HR-HPV infection after one-year follow-up to inform optimal screening, treatment, and follow-up algorithms. METHODS: We co-tested 913 previously unscreened women aged ≥30years and applied WHO-recommended treatment for all VIA/VILI-DC-positive women. Baseline prevalence of HR-HPV and HIV were 24% and 42%, respectively. RESULTS: On initial screen, 44 (5%) women were VIA/VILI-DC-positive, of whom 22 had HR-HPV infection, indicating 50% of women screened false-positive and would have been triaged for unnecessary same-day treatment. VIA/VILI-DC-positive women with HIV infection were three times more likely to be HR-HPV-positive than HIV-negative women (65% vs. 20%). All women positive for either VIA/VILI-DC or HR-HPV (n=245) were invited for repeat co-testing after one year, of which 136 (56%) returned for follow-up. Of 122 women who were HR-HPV-positive on initial screen, 60 (49%) re-tested negative, of whom 6 had received treatment after initial screen, indicating that 44% of initially HR-HPV-positive women spontaneously cleared infection after one year without treatment. Women with HIV were more likely to remain HR-HPV-positive on follow-up than HIV-negative women (61% vs. 22%, p<0.001). Treatment was offered to all VIA/VILI-DC positive women on initial screen, and to all women screening VIA/VILI-DC or HR-HPV positive on follow-up. CONCLUSIONS: We found careHPV co-testing with VIA/VILI-DC to be feasible and valuable in identifying false-positives, but careHPV screening-to-result time was too long to inform same-day treatment.

ABSTRACT

BACKGROUND: Cervical cancer screening is one of the most effective cancer prevention strategies, but most women in Africa have never been screened. In 2007, the Cameroon Baptist Convention Health Services, a large faith-based health care system in Cameroon, initiated the Women's Health Program (WHP) to address this disparity. The WHP provides fee-for-service cervical cancer screening using visual inspection with acetic acid enhanced by digital cervicography (VIA-DC), prioritizing care for women living with HIV/AIDS. They also provide clinical breast examination, family planning (FP) services, and treatment for reproductive tract infection (RTI). Here, we document the strengths and challenges of the WHP screening program and the unique aspects of the WHP model, including a fee-for-service payment system and the provision of other women's health services. METHODS: We retrospectively reviewed WHP medical records from women who presented for cervical cancer screening from 2007-2014. RESULTS: In 8 years, WHP nurses screened 44,979 women for cervical cancer. The number of women screened increased nearly every year. The WHP is sustained primarily on fees-for-service, with external funding totaling about $20,000 annually. In 2014, of 12,191 women screened for cervical cancer, 99% received clinical breast exams, 19% received FP services, and 4.7% received treatment for RTIs. We document successes, challenges, solutions implemented, and recommendations for optimizing this screening model. CONCLUSION: The WHP's experience using a fee-for-service model for cervical cancer screening demonstrates that in Cameroon VIA-DC is acceptable, feasible, and scalable and can be nearly self-sustaining. Integrating other women's health services enabled women to address additional health care needs. IMPLICATION FOR PRACTICE: The Cameroon Baptist Convention Health Services Women's Health Program successfully implemented a nurse-led, fee-for-service cervical cancer screening program using visual inspection with acetic acid-enhanced by digital cervicography in the setting of a large faith-based health care system in Cameroon. It is potentially replicable in many African countries, where faith-based organizations provide a large portion of health care. The cost-recovery model and concept of offering multiple services in a single clinic rather than stand-alone "silo" cervical cancer screening could provide a model for other low-and-middle-income countries planning to roll out a new, or make an existing, cervical cancer screening services accessible, comprehensive, and sustainable.

ABSTRACT

BACKGROUND: In 2007, the Cameroon Baptist Convention Health Services (CBCHS) implemented a screen-and-treat cervical cancer prevention program using visual inspection with acetic acid enhanced by digital cervicography (VIA-DC). METHODS: We retrospectively analyzed 46,048 medical records of women who received care through the CBCHS Women's Health Program from 2007 through 2014 to determine the prevalence and predictors of positive VIA-DC, rates of same day treatment, and cohort prevalence of invasive cervical cancer (ICC). RESULTS: Of the 44,979 women who were screened for cervical cancer, 9.0% were VIA-DC-positive, 66.8% were VIA-DC-negative, 22.0% were VIA-DC-inadequate (normal ectocervix, but portions of the transformation zone were obscured), and 2.2% were VIA-DC-uncertain (cervical abnormalities confounding VIA-DC interpretation). Risk factors significantly associated with VIA-DC-positive screen were HIV-positivity, young age at sexual debut, higher lifetime number of sexual partners, low education status and higher gravidity. In 2014, 31.1% of women eligible for cryotherapy underwent same day treatment. Among the 32,788 women screened from 2007 through 2013, 201 cases of ICC were identified corresponding to a cohort prevalence of 613 per 100,000. CONCLUSIONS: High rate of VIA-DC-positive screens suggests a significant burden of potential cervical cancer cases and highlights the need for expansion of cervical cancer screening and prevention throughout the 10 regions of Cameroon. VIA-DC-inadequate rates were also high, especially in older women, and additional screening methods are needed to confirm whether these results are truly negative. In comparison to similar screening programs in sub-Saharan Africa there was low utilization of same day cryotherapy treatment. Further studies are required to characterize possible program specific barriers to treatment, for example cultural demands, health system challenges and cost of procedure. The prevalence of ICC among women who presented for screening was high and requires further investigation.

ABSTRACT

OBJECTIVE: The World Health Organization recommends visual inspection with acetic acid (VIA) for cervical cancer screening in resource-limited settings. In Cameroon, we use digital cervicography (DC) to capture images of the cervix after VIA. This study evaluated interobserver agreement of DC results, compared DC with histopathologic results, and examined interobserver agreement among screening methods. METHOD: Three observers, blinded to each other's interpretations, evaluated 540 DC photographs as follows: (1) negative/positive for acetowhite lesions or cancer and (2) assigned a presumptive diagnosis of histopathologic lesion grade in the 91 cases that had a histopathologic diagnosis. Observer A was the actual screening nurse; B, a reproductive health nurse; C, a gynecologic oncologist; and D, the histopathologic diagnosis. We compared inter-rater agreement of DC impressions among observers A, B, and C, and with D, with Cohen kappas. RESULTS: For interpretations of DC, (negative/positive) strengths of agreement of paired observers were the following: A/B, moderate [K, 0.54; 95% confidence interval (CI), 0.47-0.61], A/C, fair (K, 0.37; 95% CI, 0.29-0.44), and B/C, moderate (K, 0.45; 95% CI, 0.37-0.53). For presumptive pathologic grading, strengths of agreement for weighted Ks were as follows: A/B, moderate (K, 0.42; 95% CI, 0.28-0.56); A/C, fair (K, 0.33; 95% CI, 0.20-0.46); B/C, fair (K, 0.54; 95% CI, 0.40-0.67); A/D, moderate (K, 0.59; 95% CI, 0.45-0.74); B/D, moderate (K, 0.58; 95% CI, 0.46-0.70); and C/D, moderate (K, 0.50; 95% CI, 0.37-0.63). CONCLUSIONS: Interobserver agreement of DC interpretations was mostly moderate among the 3 observers, between them and histopathology, and comparable to that of other visual-based screening methods, i.e., VIA, cytology, or colposcopy.

ABSTRACT

BACKGROUND: Cameroon has the highest age-standardized incidence rate of cervical cancer (30/100,000 women) in Central Africa. In 2010-2011, the Cameroon Baptist Convention Health Services (CBCHS) received donated human papillomavirus (HPV) vaccine, Gardasil, from Merck & Co. Inc. through Axios Healthcare Development to immunize 6400 girls aged 9-13 years. The aim was to inform the Cameroon Ministry of Health (MOH) of the acceptability, feasibility, and optimal delivery strategies for HPV vaccine. METHODS AND FINDINGS: Following approval by the MOH, CBCHS nurses educated girls, parents, and communities about HPV, cervical cancer, and HPV vaccine through multimedia coverage, brochures, posters, and presentations. Because educators were initially reluctant to allow immunization in schools, due to fear of adverse events, the nurses performed 40.7% of vaccinations in the clinics, 34.5% in community venues, and only 24.7% in schools. When no adverse events were reported, more schools and communities permitted HPV vaccine immunization on their premises. To recover administrative costs, CBCHS charged a fee of US$8 per 3-dose series only to those who were able to pay. Despite the fee, 84.6% of the 6,851 girls who received the first dose received all three doses. CONCLUSIONS AND LESSONS LEARNED: With adequate education of all stakeholders, HPV vaccination is acceptable and feasible in Cameroon. Following this demonstration project, in 2014 the Global Access to Vaccines and Immunization (GAVI) Alliance awarded the Cameroon MOH HPV vaccine at a price of US$4.50 per dose to immunize sixth grade girls and girls aged 10 years who are not in school in two districts of Cameroon.

ABSTRACT

OBJECTIVES: We assessed the knowledge and awareness of cervical cancer, HPV and HPV vaccine, and willingness and acceptability to vaccinate in sub-Saharan African (SSA) countries. We further identified countries that fulfill the two GAVI Alliance eligibility criteria to support nationwide HPV vaccination. METHODS: We conducted a systematic review of peer-reviewed studies on the knowledge and awareness of cervical cancer, HPV and HPV vaccine, and willingness and acceptability to vaccinate. Trends in Diphtheria-tetanus-pertussis (DTP3) vaccine coverage in SSA countries from 1990-2011 were extracted from the World Health Organization database. FINDINGS: The review revealed high levels of willingness and acceptability of HPV vaccine but low levels of knowledge and awareness of cervical cancer, HPV or HPV vaccine. We identified only six countries to have met the two GAVI Alliance requirements for supporting introduction of HPV vaccine: 1) the ability to deliver multi-dose vaccines for no less than 50% of the target vaccination cohort in an average size district, and 2) achieving over 70% coverage of DTP3 vaccine nationally. From 2008 through 2011 all SSA countries, with the exception of Mauritania and Nigeria, have reached or maintained DTP3 coverage at 70% or above. CONCLUSION: There is an urgent need for more education to inform the public about HPV, HPV vaccine, and cervical cancer, particularly to key demographics, (adolescents, parents and healthcare professionals), to leverage high levels of willingness and acceptability of HPV vaccine towards successful implementation of HPV vaccination programs. There is unpreparedness in most SSA countries to roll out national HPV vaccination as per the GAVI Alliance eligibility criteria for supporting introduction of the vaccine. In countries that have met 70% DTP3 coverage, pilot programs need to be rolled out to identify the best practice and strategies for delivering HPV vaccines to adolescents and also to qualify for GAVI Alliance support.

ABSTRACT

BACKGROUND: While it is known that sub-Saharan African countries face multiple obstacles such as cost in adopting vaccination against human papillomavirus (HPV), the crucial role nurses can play in implementing such programs has not been adequately examined. OBJECTIVES: To investigate the knowledge and awareness of HPV, primary cause of cervical cancer and HPV vaccine among nurses working at four Cameroon Baptist Convention Health Services facilities, and to explore what factors influence nurses' willingness to inform and recommend HPV vaccine to adolescents and parents attending clinics. DESIGN AND SETTING: A structured questionnaire survey was administered to a convenience sample of nursing staff working at the four health facilities. RESULTS: Of 192 eligible nurses 76 (39.6%) participated in the study. There were moderately low levels of knowledge about HPV infection and prevention of cervical cancer, but a moderately high level of knowledge about HPV vaccine. Although 90.8% acknowledged that cervical cancer is directly linked to HPV infection, nearly 32% failed to identify it as a sexually transmitted infection (STI), while 43.4% believed it is an uncommon infection. Willingness to recommend the HPV vaccine was moderate, with 69.7% intentionally initiating discussions with patients about the subject. The most important factors considered when deciding to recommend the vaccine included effectiveness (56.6%) and side effects/safety (11.8%). Cost was less of a concern (6.6%), likely due to the availability of donated vaccine. CONCLUSION: Despite high awareness about HPV, more education about the virus, cervical cancer and the vaccine are required to further increase nurses' willingness to recommend the vaccine and strengthen strategies for reaching adolescents through nurses in Cameroon.

The purpose of this study is to assess awareness, knowledge and beliefs about HPV, cervical cancer HPV vaccine and willingness to vaccinate among adolescent females aged 12-26 years at clinics and schools in the North West Region of Cameroon where the Cameroon Baptist Convention Health Services (CBCHS) conducted a sensitization and education campaign. A questionnaire survey was administered among female adolescents in schools and clinics. Descriptive statistics including frequencies, percentages and proportions were generated for independent variables and bivariate analyses (Chi square test) were used to assess the relationship between independent and outcome variables. Data were analyzed using SAS Version 9.2. Out of a sample of 650 adolescent girls 553 willingly participated in this anonymous survey. Awareness of HPV (86.8%), cervical cancer (82.3%), and prevention of HPV infections through vaccination (75.9%) was significantly higher than in previous studies conducted in Cameroon and other developing countries. Higher perceptions of risk were associated with being sexually active (p = 0.0013), age (p = 0.0031) and level of education (p = 0.0274). Age and educational level were associated with HPV knowledge (p = 0.007 and p = 0.0008), respectively. The mean level of interest in HPV vaccination was 4.0 (SD = 1.27), which is above the mean. Our data indicate high awareness about HPV, cervical cancer and HPV vaccine among adolescents, and interest in receiving the vaccine and learning about the disease. CBCHS' community education strategy effectively raised acceptability and generated demand for HPV vaccine, making it a potential model for HPV immunization in Cameroon and other developing countries.

ABSTRACT

In 2010, the Cameroon Baptist Convention Health Services (CBCHS) received a donation of HPV vaccine (Gardasil®) to immunize girls of ages 9-13 years in the North West Region of Cameroon. We evaluated the effectiveness of the CBCHS campaign program in sensitizing parents/guardians to encourage HPV vaccine uptake, identified factors that influence parents' decisions to vaccinate girls, and examined the uptake of cervical cancer screening among mothers. We conducted a cross-sectional survey in four healthcare facilities run by CBCHS, churches and other social settings. A total of 350 questionnaires were distributed and 317 were used for the analysis. There were high levels of awareness about cervical cancer, HPV and HPV vaccine. 75.5% understood HPV is sexually transmitted and 90.3% were aware of the use of vaccine as a preventive measure. Effectiveness of the vaccine (31.8%) and side effects/safety (18.4%) were the major barriers for parents to vaccinate their daughters. Bivariate analysis further revealed that the level of education (p = 0.0006), income level (p = 0.0044) and perceived risks (p = 0.0044) are additional factors influencing parents' decisions to vaccinate girls. 35.3% of women had sought a cervical cancer screening, significantly higher than the general estimated rate of screening (<10%) in other parts of Cameroon and sub-Saharan Africa. These results support the viability of a community-tailored sensitization strategy to increase awareness among the targeted audience of parents/guardians, who are critical decision-makers for vaccine delivery to children.

ABSTRACT

BACKGROUND: HPV types vary by country and HIV status. There are no data on the prevalent HPV genotypes from Cameroon. METHODS: We conducted a cross-sectional, observational study on 65 Cameroonian women. Samples were sent for HPV genotyping and Thin Prep analyses. RESULTS: 41 out of 61 samples tested (67.2%) had HPV subtypes detected. The most common high risk types encountered were: 45 (24.6%) and 58 (21.5%). HIV-positive women were more likely to test positive for any HPV (P = .014), have more than one HPV subtype (P = .003), and to test positive for the high risk subtypes (P = .007). Of those with high risk HPV, HIV-positive women were more likely to have Thin Prep abnormalities than HIV-negative women (P = .013). CONCLUSIONS: Oncogenic HPV subtypes 45 and 58 were more prevalent than those subtypes carried in the quadrivalent vaccine. Further studies are needed to assess whether the current vaccine will be effective in this region.

ABSTRACT

With funds from Elizabeth Glaser Pediatric AIDS Foundation, the Cameroon Baptist Convention Health Board implemented a program to prevent mother-to-child transmission of HIV-1 (PMTCT) as part of its routine antenatal care, with single-dose maternal and infant peripartum nevirapine (NVP) prophylaxis of HIV-positive mothers and their babies. Nurses, midwives, nurse aides, and trained birth attendants counseled pregnant women, obtained risk factor data, and offered free HIV testing with same-day results. From February 2000 through December 2004, this program rapidly expanded to 115 facilities in 6 of Cameroon's 10 provinces, not only to large hospitals but to remote health centers staffed by trained birth attendants. We trained 690 health workers in PMTCT and counseled 68,635 women, 91.9% of whom accepted HIV testing. Of 63,094 women tested, 8.7% were HIV-1-positive. Independent risk factors for HIV-1 infection included young age at first sexual intercourse, multiple sex partners, and positive syphilis serology (P < 0.001 for each). We counseled 98.7% of positive and negative mothers on a posttest basis. Of 5550 HIV-positive mothers, we counseled 5433 (97.9%) on single-dose NVP prophylaxis. Consistent training and programmatic support contributed to rapid upscaling and high uptake and counseling rates.

ABSTRACT

Pregnant women (n = 859) in rural Cameroonian prenatal clinics were screened by two rapid human immunodeficiency virus (HIV) antibody tests (rapid tests [RT]) (Determine and Hema-Strip) using either whole blood or plasma. One additional RT (Capillus, HIV-CHEK, or Sero-Card) was used to resolve discordant results. RT results were compared with HIV-1 enzyme immunoassay (EIA) and Western blot (WB) results of matched dried blood spots (DBS) to assess the accuracy of HIV RTs. DBS EIA/WB identified 83 HIV antibody-reactive, 763 HIV antibody-nonreactive, and 13 indeterminate specimens. RT results were evaluated in serial (two consecutive tests) or parallel (two simultaneous tests) testing algorithms. A serial algorithm using Determine and Hema-Strip yielded sensitivity and specificity results of 97.6% and 99.7%, respectively, whereas a parallel RT algorithm using Determine plus a second RT produced a sensitivity and specificity of 100% and 99.7%, respectively. HIV RTs provide excellent alternatives for identifying HIV infection, and their field performance could be monitored using DBS testing strategies.
