RESUMEN

The COVID-19 pandemic has reinforced the critical role of ethics and community engagement in designing and conducting clinical research during infectious disease outbreaks where no vaccine or treatment already exists. In reviewing current practices across Africa, we distinguish between three distinct roles for community engagement in clinical research that are often conflated: 1) the importance of community engagement for identifying and honouring cultural sensitivities; 2) the importance of recognising the socio-political context in which the research is proposed; and 3) the importance of understanding what is in the interest of communities recruited to research according to their own views and values. By making these distinctions, we show that current practice of clinical research could draw on anthropology in ways which are sometimes unnecessary to solicit local cultural values, overlook the importance of socio-political contexts and wider societal structures within which it works, potentially serving to reinforce unjust political or social regimes, and threaten to cast doubt on the trustworthiness of the research. We argue that more discerning anthropological engagement as well as wider collaboration with other social scientists and those working in the humanities is urgently needed to improve the ethics of current biomedical and pharmaceutical research practice in Africa.

RESUMEN

Conducting research during disease outbreaks can be ethically challenging as evidenced in the 2014-2016 Ebola outbreak in West Africa and COVID-19 pandemic. Yet, there has been little empirical research conducted for understanding the views and perspectives of different stakeholders regarding ethical issues in conducting research during disease outbreaks. This preliminary study was conducted to empirically explore African public health research stakeholders' views about research ethics issues during infectious disease outbreaks in Africa. We conducted an online survey of 330 participants attending the International Conference on Re-emerging and Emerging Infectious Disease (ICREID) meeting that took place from 13-15 March 2019 in Addis Ababa, Ethiopia to elicit their views on various research ethics complexities experienced in the 2014 Ebola outbreak. Study results revealed some divergent views on several ethical themes including: ethics of using unregistered interventions in outbreaks; acceptable study design; ethics review processes; risks-benefit assessment; exclusion of pregnant women and children; and biological sample and data sharing. Majority (76.3%) of respondents felt that in the absence of available standard treatments or prevention modalities, the use of investigational interventions can be ethically justifiable if there is a strong scientific rationale and favorable risk-benefit ratio. Regarding conventional placebo-controlled trials during outbreaks with high case fatality rates, respondents that considered this unethical were more than three times those that felt such design were ethically justifiable. We were somewhat surprised that a majority (almost 60%) of respondents were satisfied with the exclusion of pregnant women and children in clinical trials during outbreaks. All respondents concurred with the prioritization of informed consent for research during an outbreak. Based on our findings, research ethics guidance is needed to equip research stakeholders in dealing with ethical complexities arising in the conduct of research during emerging disease outbreaks-especially regarding using experimental interventions; placebo trial design; inclusion or justified exclusion of pregnant women and children; and biological sample/data sharing. The findings will be used in ongoing efforts of developing a consultative and coherent African-centric framework to support ethical conduct of research for future emerging infectious disease outbreaks in Africa.

RESUMEN

In South Africa, biomedical research cannot commence until it has been reviewed and approved by a local research ethics committee (REC). There remains a dearth of empirical data on the nature and frequency of ethical issues raised by such committees. This study sought to identify ethical concerns typically raised by two South African RECs. Meeting minutes for 180 protocols reviewed between 2009 and 2014 were coded and analyzed using a preexisting framework. Results showed that the most frequent queries involved informed consent, respect for participants, and scientific validity. Interestingly, administrative issues (non-ethical) such as missing researchers' CVs and financial contracts emerged more frequently than ethical questions such as favorable risk/benefit ratio and fair participant selection. Although not generalizable to all RECs, our data provide insights into two South African RECs' review concerns. More education and awareness of the actual ethical issues typically raised by such committees might help improve review outcomes and relationships between researchers and RECs.

RESUMEN

Research Ethics Committees (RECs) are mandated to protect human participants by conducting ethical reviews of biomedical research. To date, there is a dearth of information on the structure, functioning, and outcomes of RECs in Africa. This article reviews empirical studies investigating African RECs, with the aim of providing an overview of what is known and identifying gaps in our knowledge. We conducted a literature search of the EBSCO, PubMed, and Google Scholar electronic databases. Twenty-three empirical studies reporting on the structure, functions, and outcomes of African RECs were included in our analysis. The review yielded limited systematic data on RECs in Africa. Available empirical evidence suggests that challenges hampering the effective functioning of RECs included lack of membership diversity, scarcity of resources, insufficient training of members, inadequate capacity to review and monitor studies, and lack of national ethics guidelines and accreditation. Relatively little data on the review outcomes of African RECs were described. There is an ongoing need for concerted efforts from various stakeholders to support capacity development and enhancement of African RECs.

RESUMEN

The abundance of South African clinical and public health research data has the potential to unlock important and valuable future advances in biomedical science. Amid increasing calls for more effective sharing of individual-level data, commitment to promote access to research data is evident within South Africa's public research sector, but national guidance and regulation are absent. This qualitative study examined the perceptions, experiences and concerns of 32 research stakeholders about data-sharing practices. There was consensus about the utility of data sharing in publicly funded health research. However, disparate views emerged about the possible harms and benefits of sharing data and how these should be weighed. The relative dearth of policies governing data-sharing practices needs to be addressed and a framework of support developed that incentivizes data-sharing practices for researchers that are both ethical and effective.

RESUMEN

Mycobacterium tuberculosis complex (MTBC) causes tuberculosis (TB) in humans and animals. We investigated the presence of MTBC in cattle milk and its drug resistance using polymerase chain reaction (PCR). Two hundred samples (100 mL each) were obtained from a dairy farm in the Nkonkobe region of South Africa. The samples were processed using the modified Petroff method. DNA was isolated using a Zymo Bacterial DNA kit and amplified using Seeplex(®) MTB Nested ACE assay. The Genotype(®) Mycobacterium tuberculosis-multidrug resistantplus (MTBDRplus) assay was used to perform drug susceptibility and detection of mutations conferring resistance to isoniazid (INH) and rifampicin (RIF). Eleven samples tested positive for MTBC DNA using the Seeplex(®) MTB Nested ACE assay. The Genotype(®) MTBDRplus assay showed that 10/11 samples were resistant to both INH and RIF i.e., multi-drug resistant (MDR). The most and least frequent rpoB mutations detected in RIF resistant samples were H526Y (9/10) and D516V (2/10) respectively. None of the INH resistant samples harbored mutations in the katG gene. However, all of them harbored the T8A mutation in the inhA gene. These results have clinical and epidemiological significance and calls for further studies and necessary actions to delineate the situation.
