Cabenuva®: Differentiated service delivery and the community Pharmacists’ roles in achieving UNAIDS 2030 target in Nigeria

The approval of the novel long-acting HIV injection; Cabenuva®- Cabotegravir and Rilpivirine injectable formulation) and the recent call by the World Health Organization for promoting community-based ART management, underscore the remarkable progress towards meeting the Joint United Nations Programme on HIV/AIDS (UNAIDS) 95–95–95 targets by 2030.As the availability of antiretroviral therapy (ART) for the treatment of HIV/AIDS has increased in resource-limited settings, there has been a move to develop and implement alternative treatment delivery models such as Differentiated Service Delivery (DSD) in high prevalence countries to meet the global targets for HIV treatment while maintaining the quality of care. However, there is limited data on the involvement of community pharmacies in the delivery of ART within the community. Although, in western countries, several studies have documented the different roles community pharmacists can play in the management of HIV/AIDS. Community pharmacists are the most accessible and first points of health care for most clients. They are trusted, highly trained health care professionals. They should be incorporated and allowed to administer the Cabenuva® injection if the battle against the HIV pandemic is to be totally won. In this paper, we, therefore, aim to explore how the community pharmacist can be positioned in HIV service delivery regarding the administration of the Novel long-acting Cabenuva® injection formulation. It is therefore recommended that the Nigerian government embrace community pharmacy-led drug administration initiatives and embark on accredited training programmes for the profession in line with drug administration services. The government should also put in place necessary funding mechanisms for community pharmacists for the extra workload placed on them in administering injection drug formulation in their respective pharmacies.     

Prostate cancer health and cultural beliefs of black men: The Florida Prostate Cancer Disparity Project

Background

Since behavioral factors are significant determinants of population health, addressing prostate cancer (CaP)-related health beliefs and cultural beliefs are key weapons to fight this deadly disease. This study investigated the health beliefs and cultural beliefs of black men relative to CaP, and the key socio-demographic correlates of these beliefs.

Methods

The study design was a cross-sectional survey of 2,864 Florida black men, age 40 to 70, on their perceived susceptibility, perceived severity, attitude, outcomes beliefs, perceived behavioral control, CaP fatalism, religiosity, temporal orientation, and acculturation relative to CaP screening and prevention.

Results

The men reported favorable attitude and positive outcome beliefs, but moderate perceived behavioral control, CaP susceptibility and CaP severity. They also had low level of acculturation, did not hold fatalistic beliefs about CaP, had high religious coping skills and had high future time perspective. Several demographic variables were found to be associated with health beliefs and cultural beliefs.

Discussion

Our study provides rich data with regard to the health and cultural beliefs that might serve to inform the development of CaP control initiative for US-born and foreign-born black men.

The aim of this study was to examine the relationship between waist–hip ratio and the risk of breast cancer in an urban Nigerian population.     

Sexual behaviour and contraceptive practice of future doctors in Southwest Nigeria.

The sexual behaviour and contraceptive practice of 498 clinical students of a randomly selected medical college in Southwest Nigeria was studied in June 2003. More than two-thirds (67.5%) of the students had (ever had) sexual intercourse while 49.8% of them had ever used contraception. Only 26.1% of the 119 sexually active students used contraception during their last sexual intercourse. The most common contraceptive methods ever used by the students were the condom (54.6%) and rhythm method (39.5%) though a third of them incorrectly identified the limits of the fertile period. Contraception for single sexually active students was disapproved by 11.2% of the participants while 9.8% of them regarded avoidance of HIV patients in the hospital as a preventive measure against HIV infection. This survey reinforces the need for integration of a suitable sexuality course into our medical undergraduate curriculum in order to facilitate the delivery of reproductive health programmes in the future.     

In vitro and in vivo cytotoxic activity of native and ricin conjugated monoclonal antibodies to HBs antigen for Alexander primary liver cell carcinoma cells and tumours.

In in vitro and in vivo systems, native or ricin conjugated monoclonal anti-HBs, are capable of inhibiting or slowing the growth of Alexander primary hepatocellular carcinoma cells. Failure of the immune response to this component of the hepatitis B virus may be one permissive factor in the development of some primary liver cell carcinoma in chronic HBV carriers.     

Acceptability of prenatal HIV screening at the primary care level in Nigeria.

A survey of 333 pregnant women receiving antenatal care at the primary healthcare centres in Sagamu Local Government Area of Ogun State, southwest Nigeria was conducted between January and March 2005 to assess the acceptability of prenatal HIV screening among them. A total of 325 (97.8%) of the respondents were aware of HIV/AIDS but only 181 (54.3%) of them believed it is a problem in Nigeria. A total of 257 (77.2%) respondents agreed to undergo voluntary counselling and HIV testing (VCT). Multivariate logistic regression analysis of associated factors indicated that being married, self-perception of no risk of HIV infection, awareness of benefits of prenatal HIV testing and Christianity are independent predictors of acceptance of prenatal HIV testing in this population. Most of the respondents (78.9%) who were unwilling to take the test cited fear of being infected with its consequences of stigma and discrimination as the reason for their attitude. The survey suggests that a successful integration of VCT programme into the existing primary healthcare services for prevention of vertical HIV transmission is feasible in this part of Nigeria.     

Performance of a rapid antigen test for the diagnosis of congenital malaria

OBJECTIVE: To assess the performance of OptiMAL, a rapid malaria antigen capture dipstick, in diagnosing congenital malaria. METHODS: Live newborns aged 0-3 days, delivered at Olabisi Onabanjo University Teaching Hospital, Sagamu, Nigeria between August 2004 and January 2005, were screened for malaria parasitaemia with an immunochromatographic test (OptiMAL) and blood film microscopy. OptiMAL detects plasmodium lactate dehydrogenase (pLDH). RESULTS: Twenty-one of 192 newborns (10.9%) were diagnosed with congenital malaria by blood film microscopy. The OptiMAL test was negative in all infants. CONCLUSION: OptiMAL rapid malaria antigen capture dipstick might not be useful for diagnosing malaria parasitaemia in newborns. Blood film microscopy remains the gold standard for the diagnosis of congenital malaria.     

Genetic polymorphisms in uridine diphospho-glucuronosyltransferase 1A1 and breast cancer risk in Africans

The UDP-glucuronosylatransferase 1A1 (UGT1A1) gene is involved in the metabolism of estrogen and detoxification of potential carcinogens. The number of TA repeats in the promoter region of UGT1A1 has been linked to breast cancer risk, but results varied by race. We performed a comprehensive assessment of genetic polymorphisms in the UGT1A1 gene, and examined these polymorphisms and TA repeats in relation to breast cancer risk in a case-control study in Nigeria. 512 breast cancer cases and 226 community controls were genotyped for UGT1A1. Compared with high-activity TA repeat genotypes, the odds ratios (OR) for low-activity and moderate-activity genotypes were 0.47 (95% confidence interval CI, 0.26-0.83) and 0.64 (95% CI, 0.39-1.06), respectively, in premenopausal women (P = 0.009 for trend), but no association was observed in postmenopausal women (P = 0.24). The effect of TA repeats was also differentiated by age: the OR was 0.39 (95% CI 0.21-0.71) for low-activity genotypes and 0.58 (95% CI 0.33-1.00) for moderate-activity genotypes in women <45 years old (P = 0.002 for trend), but no association was observed in women >/=45 years old (P = 0.15). Haplotype analysis showed that UGT1A1 haplotypes were highly diverse with blocked structures. We found a specific haplotype in block 2 that was significantly associated with a 2.1-fold elevated risk (95% CI 1.05-4.39; P = 0.04). In contrast with previous studies, we found low-activity TA repeat alleles were protective against breast cancer among premenopausal indigenous Africans, suggesting that the role of UGT1A1 in breast cancer development may vary by population, presumably due to different environmental and genetic modifier effects.     

National data system on near miss and maternal death: shifting from maternal risk to public health impact in Nigeria

Background

The lack of reliable and up-to-date statistics on maternal deaths and disabilities remains a major challenge to the implementation of Nigeria's Road Map to Accelerate the Millennium Development Goal related to Maternal Health (MDG-5). There are currently no functioning national data sources on maternal deaths and disabilities that could serve as reference points for programme managers, health advocates and policy makers. While awaiting the success of efforts targeted at overcoming the barriers facing establishment of population-based data systems, referral institutions in Nigeria can contribute their quota in the quest towards MDG-5 by providing good quality and reliable information on maternal deaths and disabilities on a continuous basis. This project represents the first opportunity to initiate a scientifically sound and reliable quantitative system of data gathering on maternal health profile in Nigeria.

Objective

The primary objective is to create a national data system on maternal near miss (MNM) and maternal mortality in Nigerian public tertiary institutions. This system will conduct periodically, both regionally and at country level, a review of the magnitude of MNM and maternal deaths, nature of events responsible for MNM and maternal deaths, indices for the quality of care for direct obstetric complications and the health service events surrounding these complications, in an attempt to collectively define and monitor the standard of comprehensive emergency obstetric care in the country.

Methods

This will be a nationwide cohort study of all women who experience MNM and those who die from pregnancy, childbirth and puerperal complications using uniform criteria among women admitted in tertiary healthcare facilities in the six geopolitical zones in Nigeria. This will be accomplished by establishing a network of all public tertiary obstetric referral institutions that will prospectively collect specific information on potentially fatal maternal complications. For every woman enrolled, the health service events (care pathways) within the facility will be evaluated to identify areas of substandard care/avoidable factors through clinical audit by the local research team. A summary estimate of the frequencies of MNM and maternal deaths will be determined at intervals and indicators of quality of care (case fatality rate, both total and cause-specific and mortality index) will be evaluated at facility, regional and country levels.

Management

Overall project management will be from the Centre for Research in Reproductive Health (CRRH), Sagamu, Nigeria. There will be at least two meetings and site visits for efficient coordination of the project by regional coordinators and central coordinating staff. Data will be transferred electronically by hospital and regional coordinators and managed at the Data Management Unit of CRRH, Sagamu, Nigeria.

Expected outcomes

The outcome of the study would provide useful information to the health practitioners, policy-makers and international partners on the strengths and weaknesses of the infrastructures provided for comprehensive emergency obstetric care in Nigeria. The successful implementation of this project will pave way for the long-awaited Confidential Enquiries into Maternal Deaths that would guide the formulation and or revision of obstetric policies and practices in Nigeria. Lessons learnt from the establishment of this data system can also be used to set up similar structures at lower levels of healthcare delivery in Nigeria.
