Item Correlates of uptake of HIV testing among children and young adolescents in Akwa- Ibom state, Nigeria: a secondary data analysis of the Akwa-Ibom aids indicator survey, 2017(BMC Pediatrics, 2021) Adetoro, D.; Khamofu, H.; Badru, T.; Markson, J.; Adedokun, O.; Sandah-Abubakar, N.; Dafa, I.; Chen, M.; Chiegil, R.; Torpey, K.Background: In order to end the AIDS epidemic by 2030, there is a need to significantly reduce the rate of new infection among children and young adolescents. Identifying the correlates of testing behaviour is necessary to improve HIV testing campaigns by refining messages that target individuals in this age group. The objective of this study was to determine the correlates of HIV testing among children and young adolescents in Akwa-Ibom, Nigeria. Methods: The outcome was a secondary data analysis of the 2017 Akwa-Ibom AIDS Indicator Survey. Data of 4037 children and young adolescents aged 0–14 years was assessed in this study. Analysis was done using STATA version 16. Chi-squared test and logistic regression models were used to measure association and its strength between uptake of HIV testing and some independent variables (child/caregiver’s age, sex, educational status, child’s location, caregiver’s knowledge of HIV and caregiver ever tested for HIV) at 5% significance level. Results: Result showed that only 14.2% of the children and young adolescents have been tested for HIV. Previous history of blood transfusion (AOR = 5.33, 95%C.I = 2.60–10.92, P = < 0.001), caregiver’s level of education (AOR = 2.67, 95%C.I = 1.30–5.51, P = 0.008) and caregiver ever tested for HIV (AOR = 8.31, 95%C.I = 5.67–12.19, P = < 0.001) were significantly associated with uptake of HIV testing. Conclusion: This study concludes that a large proportion of children and young adolescents in Akwa-Ibom state have never been tested for HIV. There is a need for HIV testing interventions to be targeted towards this age groups and their parents/guardian. Addressing the knowledge gap amongst caregivers especially in rural areas is crucial towards improving the effectiveness of HIV testing interventions.Item The effects of centering pregnancy on maternal and fetal outcomes in northern Nigeria; a prospective cohort analysis(BioMed Central Ltd., 2018-05) Eluwa, G.I.; Adebajo, S.B.; Torpey, K.; Shittu, O.; Abdu-Aguye, S.; Pearlman, D.; Bawa, U.; Olorukooba, A.; Khamofu, H.; Chiegli, R.Background: Maternal and infant mortality remains high in Nigeria primarily due to low use of skilled birth attendants. Huge disparities exist between southern and northen Nigeria on use of skilled birth attendants with south significantly higher than the north. We assessed the effect of centering pregnancy group (CPG) antenatal care on the uptake of antenatal care (ANC), facility delivery and immunization rates for infants in Kano state. Methods: Between December 2012 and May 2014, pregnant women with similar sociodemographics and obstetric history were enrolled into intervention (CPG) and control groups and followed up prospectively. Chi-square tests were conducted to compare the differences between the intervention and the control groups with respect to background characteristics and intervention outcomes. Logistic regression was used to measure the associations between CPG and uptake of services for mother-baby pairs in care. Results: A total of 517 (260 in the control group and 257 in the CPG) pregnant women enrolled and participated in the study. Thirty-six percent of women in the control group attended ANC at least once in 2nd and 3nd trimester compared to 49% of respondents in the CPG (p < 0.01). Health facility delivery was higher among CPG (13% vs. 8%; p < 0.01). When controlled for age, number of previous pregnancies, number of term deliveries, number of children alive and occupation of respondent or their spouses, respondents who participated in the CPGs compared to those who did not, were more likely to attend at least one antenatal care (ANC) session in the third trimester [adjusted risk ratio (ARR):1.52; 95% CI:1.36-1.69], more likely to immunize their babies at six weeks [ARR: 2.23; 95% CI: 1.16-4.29] and fourteen weeks [ARR: 3.46; 95% CI: 1.19-10.01] and more likely to use health services [ARR: 1.50; 95% CI: 1.06-2.13]. Conclusion: Centering or group pregnancy showed a positive effect on the use of antenatal services, facility delivery and postnatal services and thus is a promising intervention to increase uptake of maternal health care services in northern Nigeria. The low facility delivery remains a cause for alarm and requires further investigation to improve facility delivery in northern Nigeria. © 2018 The Author(s).Item HIV comprehensive knowledge and prevalence among young adolescents in Nigeria: evidence from Akwa Ibom AIDS indicator survey, 2017(BMC Public Health, 2020-01-13) Mwaisaka, J.; Badru, T.; Khamofu, H.; Agbakwuru, C.; Adedokun, O.; Pandey, S.R.; Essiet, P.; James, E.; Chen-Carrington, A.; Mastro, T.D.; Aliyu, S.H.; Torpey, K.Background: Despite the recent increase in HIV infections among adolescents, little is known about their HIV knowledge and perceptions. This study, therefore, sought to examine the factors associated with comprehensive HIV knowledge, stigma, and HIV risk perceptions among young adolescents aged 10–14 years in Akwa Ibom State, Nigeria. Additionally, consenting parents and assenting young adolescents were tested for HIV. Methods: We used cross-sectional data from the 2017 Akwa Ibom AIDS Indicator Survey to analyze comprehensive HIV knowledge, stigma, and HIV risk perceptions among young adolescents. Demographic characteristics of young adolescents were summarized using descriptive statistics. Chi-square test (or Fisher’s exact test in cases of small subgroup sample sizes) was used to elicit associations between demographics and study outcomes. Separate multivariable logistic regression models were then conducted to determine associations with the study outcomes. Sampling weights were calculated in order to adjust for the sample design. P-values less than 0.05 were considered to be significant. Results: A total of 1818 young adolescents were interviewed. The survey highlighted significant low levels of comprehensive HIV knowledge (9.4%) among young adolescents. Adolescent-parent discussions [AOR = 2.19, 95% C.I (1.10–4.38), p = 0.03], schools as sources of HIV information [AOR = 8.06, 95% C.I (1.70–38.33), p < 0.001], and sexual activeness [AOR = 2.55, 95% C.I (1.16–5.60), p = 0.02] were associated with comprehensive HIV knowledge. Majority (93%) of young adolescents perceived themselves not to be at risk of HIV. Overall, 81.5% of young adolescents reported stigmatizing tendencies towards people living with HIV. HIV prevalence among young adolescents was 0.6%. Conclusions: Results indicate low comprehensive HIV knowledge among young adolescents. Our findings suggest that there is a need for increased attention towards young adolescents particularly in the provision of comprehensive, functional sexuality education, including HIV at the family- and school-levels. Consequently, age appropriate interventions are needed to address the epidemiological risks of young adolescents that are influenced by a myriad of social issuesItem Integrating cervical cancer screening with HIV care in a district hospital in Abuja, Nigeria(Nigerian Medical Journal, 2013) Odafe, S.; Torpey, K.; Khamofu, H.; et al.Background: Human immunodeficiency virus positive (HIV+) women have a higher risk of developing invasive cervical cancer compared with uninfected women. This study aims to document programmatic experience of integrating cervical cancer screening using Visual Inspection and Acetic Acid (VIA) into HIV care as well as to describe patients’ characteristics associated with positive VIA findings amongst HIV+ women. Materialsand Methods:Across‑sectional study analysed routine service data collected at the antiretroviral therapy (ART) and cervical cancer screening services. Our program integrated screening for cervical cancer using VIA technique to HIV care and treatment services through a combination of stakeholder engagement, capacity building for health workers, creating a bi‑directional referral between HIV and reproductive health (RH) services and provider initiated counselling and screening for cervical cancer. Information on patients’ baseline and clinical characteristics were captured using an electronic medical records system and then exported to Statistical Package for the Social Sciences (SPSS). Logistic regression model was used to estimate factors that influence VIA results. Results: A total of 834 HIV+ women were offered VIA screening between April 2010 and April 2011, and 805 (96.5%) accepted it. Complete data was available for 802 (96.2%) women. The mean age at screening and first sexual contact were 32.0 (SD 6.6) and 18.8 (SD 3.5) years, respectively. VIA was positive in 52 (6.5%) women while 199 (24.8%) had a sexually transmitted infection (STI). Of the 199 who had a STI, eight (4.0%) had genital ulcer syndrome, 30 (15.1%) had lower abdominal pain syndrome and 161 (80.9%) had vaginal discharge syndrome. Presence of lower abdominal pain syndrome was found to be a significant predictor of a positive VIA result (P = 0.001). Women with lower abdominal pain syndrome appeared to be more likely (OR 47.9, 95% CI: 4.8‑480.4, P = 0.001) to have a positive VIA result. Conclusion: The high burden of both HIV and cervical cancer in developing countries makes it a necessity for integrating services that offer early detection and treatment for both diseases. The findings from our study suggest that integrating VIA screening into the package of care offered to HIV+ women is feasible and acceptable.Item Performance evaluation of BD FACSPresto™ point of care CD4 analyzer to enumerate CD4 counts for monitoring HIV infected individuals in Nigeria(Public Library of Science, 2017) Negedu-Momoh, O.R.; Jegede, F.E.; Yakubu, A.; Balogun, O.; Abdullahi, M.; Badru, T.; Oladele, E.A.; Agbakwuru, C.; Khamofu, H.; Torpey, K.Background: Despite the upsurge in support and intervention of donor agencies in HIV care and treatment programing in Sub-Sahara African, antiretroviral (ART) programs are still confronted with access and coverage challenges which influence enrolment of new patients. This study investigated the validity of point of care BD FACSPresto™ CD4 analyzer for CD4+ cell count, overall agreement, correlation, sensitivity, and specificity in comparison to a reference standard flow cytometry method. We also assessed the feasibility of use among nonlaboratorians. Methods Blood samples from 300 HIV infected individuals were analyzed for CD4+ T cell and CD4%, using finger prick capillary sample from 150 PMTCT clients and 150 ART clients at Murtala Mohammed Specialist Hospital, Kano, Nigeria. Their venous samples were compared on a flow cytometry reference method using BD FACSCount CD4+ count system. The accuracy of the BD FACSPresto machine in comparison to BD FACSCount was evaluated. Statistical analysis was carried out using STATA (version 12). Bland-Altman method and correlation analysis were used to analyze agreement between both measurements. In addition, sensitivity and specificity of both measurements were determined. Statistical significance was set at p-value <0.05. Results The mean bias and limit of agreement for CD4+ count between BD FACSPresto and BD FACS count machine were 7.49 (95% CI: 2.44 to 12.54) and -8.14 to 96.39 respectively. Further analysis revealed close agreement between BD FACSPresto and BD FACSCount with no significant difference between the two methods (p = .0.95). Using a threshold of 500 cells/μL, sensitivity and specificity of BD FACSPresto were 95.1% and 97.1% respectively, compared to BD FACSCount. There was no statistically significant difference in the misclassification between BD FACSPresto and BD FACSCount results (p = 0.23). Furthermore, sensitivity and specificity were similar when BD FACSPresto machine was operated by a nurse or laboratory scientist, there was no substantial difference in testing variability observed between laboratory and non-laboratory operators using the BD FACSPresto analyzer. Conclusions Overall, BD FACSPresto Point of Care CD4+ count finger stick capillary blood results is a reliable method in comparison to venous sample cytometry method and no significant difference variability observed between laboratory personnel and non-laboratory operators. The BD FACSPresto is simple, more robust and easy to use equipment without significant variability in reliability by non-laboratory health care workers hence will be a valuable instrument in increasing access and coverage of CD4 estimations in developing countries. The introduction of the BD FACSPresto POC analyzer has a high potential in reducing patients waiting time and improving the overall quality of ART service and clients' satisfaction especially in rural settings. © 2017 Negedu-Momoh et al.

In order to address this, scale-up was planned with activities organized into 3 phases. This paper describes the process undertaken in eight high burden Nigerian states to rapidly close PMTCT coverage gaps at facility and population levels between February 2013 and March 2014. Methods Activities were grouped into three phases-pre-assessment phase (engagement of a wide range of stakeholders), assessment (rapid health facility assessment, a cross sectional survey using mixed methods conducted in the various states between Feb and May 2013 and impact modelling), and post-assessment (drawing up costed state operational plans to achieve eMTCT by 2015, data-driven smart scale-up). Results Over a period of 10 months starting June 2013, 2044 facilities were supported to begin provision of PMTCT services. This increased facility coverage from 8% to 50%. A 246% increase was also recorded in the number of pregnant women and their families who have access to HIV testing and counselling in the context of PMTCT. Similarly, access to antiretrovirals for PMTCT has witnessed a 152% increase in these eight states between October 2013 and October 2014 Conclusion A data-driven and participatory approach can be used to rapidly scale-up PMTCT services at community and facility levels in this region. These results present us with hope for real progress in Nigeria. We are confident that the efforts described here will contribute significantly to eliminating new pediatric HIV infection in Nigeria.
