RESUMO

BACKGROUND: HIV molecular epidemiology is increasingly recognized as a vital source of information for understanding HIV transmission dynamics. Despite extensive use of these data-intensive techniques in both research and public health settings, the ethical issues associated with this science have received minimal attention. As the discipline evolves, there is reasonable concern that existing ethical and legal frameworks and standards might lag behind the rapid methodological developments in this field. This is a follow-up on our earlier work that applied a predetermined analytical framework to examine the perspectives of a sample of scientists from the fields of epidemiology, public health, virology and bioethics on key ethical issues associated with HIV molecular epidemiology in HIV network research. METHODS: Fourteen in-depth interviews were conducted with scientists from the fields of molecular epidemiology, public health, virology and bioethics. Inductive analytical approaches were applied to identify key themes that emerged from the data. RESULTS: Our interviewees acknowledged the potential positive impact of molecular epidemiology in the fight against HIV. However, they were concerned that HIV phylogenetics research messages may be incorrectly interpreted if not presented at the appropriate level. There was consensus that HIV phylogenetics research presents a potential risk to privacy, but the probability and magnitude of this risk was less obvious. Although participants acknowledged the social value that could be realized from the analysis of HIV genetic sequences, there was a perceived fear that the boundaries for use of HIV sequence data were not clearly defined. CONCLUSIONS: Our findings highlight distinct ethical issues arising from HIV molecular epidemiology. As the discipline evolves and HIV sequence data become increasingly available, it is critical to ensure that ethical standards keep pace with biomedical advancements. We argue that the ethical issues raised in this study, whether real or perceived, require further conceptual and empirical examination.

RESUMO

The reduced costs of DNA sequencing and the use of such data for HIV-1 clinical management and phylogenetic analysis have led to a massive increase of HIV-1 sequences in the last few years. Phylogenetic analysis has shed light on the origin, spread and characteristics of HIV-1 epidemics and outbreaks. Phylogenetic analysis is now also being used to advance our knowledge of the drivers of HIV-1 transmission in order to design effective interventions. However, HIV phylogenetic analysis presents unique ethical challenges, which have not been fully explored. This review presents an analysis of what appear to be key ethical issues in HIV phylogenetics in the hope of stimulating further conceptual and empirical work in this rapidly emerging area. We structure the review using the Emanuel Framework, a systematic, holistic framework, which has been adapted for use in developing countries, which bear the brunt of the HIV-1 pandemic.

RESUMO

: Participant safety and data integrity, critical in trials of new investigational drugs, are achieved through honest participant report and precision in the conduct of procedures. HIV prevention post-trial access studies in middle-income countries potentially offer participants many benefits including access to proven efficacious but unlicensed technologies, ancillary care that often exceeds local standards-of-care, financial reimbursement for participation and possibly unintended benefits if participants choose to share or sell investigational drugs. This case study examines the possibility that this combination of benefits may constitute an undue inducement for some participants in middle-income countries, where economic challenges are prevalent. A case study is presented of a single participant in a cohort of 382 participants who used concealment, fabrication and deception to ensure eligibility for a post-trial access study of an unlicensed HIV prevention technology at potential risk to her health and that of her fetus. A root cause analysis revealed her desire to access HIV prevention during an unplanned pregnancy with a partner whose faithfulness was in question. Researchers should consider implementation of systems to efficiently identify similar cases without inconveniencing the majority of participants TRIAL REGISTRATION NUMBER: NCT01691768.

RESUMO

Journal editors instruct authors to describe human participant protections in original research reports. However, little is known about African biomedical journal authors' adherence to such journal editors' instructions. This study investigated changes in editors' instructions to authors and authors' reporting of research ethics information in selected African biomedical journals between 2008 and 2017. Twelve selected journal websites and online articles were reviewed in Eastern, Southern, and Western African [ESWA] countries. A pre-tested schema and a checklist were used to collect data from journal websites and articles published in 2008 and 2017, and the data were analysed using descriptive and inferential statistics. Half of the journals requested prospective authors to disclose ethics approval and related issues in their manuscripts between 2008 and 2017. There was a significant increase in instructions to authors regarding information on the protection of research participants within this period; more authors complied with these requirements in 2017 than in 2007.

RESUMO

BACKGROUND: A recent paper presents an argument and mechanism for the possible stopping of clinical trials early based on opportunity costs. DISCUSSION: Although we agree that the costs and opportunity costs of clinical trials need to be reduced wherever possible, we raise concerns about the motivation and mechanism for stopping clinical trials early raised by Lavery et al. SUMMARY: We argue that there are already enough acceptable criteria and actors in the clinical trials arena to justify early stoppage of clinical trials, and argue that factors other than efficacy need to be carefully considered, especially in developing country contexts.

RESUMO

The use of phylogenetics in HIV molecular epidemiology has considerably increased our ability to understand the origin, spread, and characteristics of HIV epidemics. Despite its potential to advance knowledge on HIV transmission dynamics, the ethical issues associated with HIV molecular epidemiology have received minimal attention. In-depth interviews were conducted with scientists from diverse backgrounds to explore their perspectives on ethical issues associated with phylogenetic analysis of HIV genetic data as applied to HIV transmission dynamics studies. The Emanuel framework was used as the analytical framework. Favorable risk-benefit ratio and informed consent were the most invoked ethical principles and fair participant selection the least. Fear of loss of privacy and disclosure of HIV transmission were invariably cited as key ethical concerns. As HIV sequence data become increasingly available, comprehensive guidelines should be developed to guide its access, sharing and use, cognizant of the potential harms that may result.

RESUMO

HIV prevention trials provide a prevention package to participants to help prevent HIV acquisition. As new prevention methods are proven effective, this raises ethical and scientific design complexities regarding the prevention package or standard of prevention. Given its high HIV incidence and prevalence, South Africa has become a hub for HIV prevention research. For this reason, it is critical to study the implementation of relevant ethical-legal frameworks for such research in South Africa. This qualitative study used in-depth interviews to explore the practices and perspectives of eight members of South African research ethics committees (RECs) who have reviewed protocols for HIV vaccine trials. Their practices and perspectives are compared with ethics guideline requirements for standards of prevention.

RESUMO

The Emanuel, Wendler, and Grady framework was designed as a universal tool for use in many settings including developing countries. However, it is not known whether the work of African health research ethics committees (RECs) is compatible with this framework. The absence of any normative or empirical weighting of the eight principles within this framework suggests that different health RECs may raise some ethical issues more frequently than others when reviewing protocols. We used the Emanuel et al. framework to assess, code, and rank the most frequent ethical issues considered by a biomedical REC during review of research protocols for the years 2008 to 2012. We extracted data from the recorded minutes of a South African biomedical REC for the years 2008 to 2012, designed the data collection sheet according to the Emanuel et al. framework, and removed all identifiers during data processing and analysis. From the 98 protocols that we assessed, the most frequent issues that emerged were the informed consent, scientific validity, fair participant selection, and ongoing respect for participants. This study represents the first known attempt to analyze REC responses/minutes using the Emanuel et al. framework, and suggests that this framework may be useful in describing and categorizing the core activities of an REC.

RESUMO

HIV disproportionately affects women in developing countries, especially in Southern Africa. Women thus stand to benefit most from a successful HIV vaccine and must participate in trials to test appropriate, gender-specific products. Several HIV vaccine efforts are currently underway in Africa. Participation in HIV vaccine trials requires that participants not only understand the complex nature of trial procedures, but that they also have autonomous decisional capacity to enroll. Given that the risk factors inherent in women's greater vulnerability constitute an intricate mix of biological, economic and social variables, will women's very vulnerability to HIV be an obstacle to ethical participation in vaccine development? This paper addresses some of the challenges underlying the successful recruitment of women into vaccine research and makes research and policy recommendations for the ethical inclusion of women in HIV vaccine trials in Africa.

RESUMO

The new National Health Act has clarified that children may take part in "non-therapeutic" research (NTR) and the age at which they may provide independent consent to such research, viz. at legal majority. However, the Act will require consent from the Minister of Health for all research classed as NTR and involving minors regardless of the level of risk. This requirement is overly broad. It will require that low-risk research without direct benefits, which might be adequately reviewed by an accredited research ethics committee (REC), must also be reviewed by the Minister. As it currently stands this requirement serves no plausible ethical purpose, will cause delays and discourage essential research on the needs of children, and may inspire researchers and RECs alike to "foil the system". We argue that in the long term there should be comprehensive law reform for child research. However, in the short term, amendments should be made to the Act to narrow the scope of this provision. The amendment should require ministerial consent for research that is currently not approvable by an REC in terms of national ethical guidelines, namely, research that does not hold out direct benefit but presents more than a minor increase over minimal risk. If our law reform recommendations are rejected, we favour the delegation of this task to RECs because, if they receive appropriate training, they should be competent to conduct it. We accept the disadvantages, namely that the same body will review protocols twice from slightly different perspectives and that certain categories of research will remain unapprovable.
