Clinical questionWhat is the role of drug interventions in the treatment and prevention of covid-19?RecommendationsThe first version on this living guidance focuses on corticosteroids. It contains a strong recommendation for systemic corticosteroids in patients with severe and critical covid-19, and a weak or conditional recommendation against systemic corticosteroids in patients with non-severe covid-19. Corticosteroids are inexpensive and are on the World Health Organisation list of essential medicines.Howthis guideline was created This guideline reflects an innovative collaboration between the WHO and the MAGIC Evidence Ecosystem Foundation, driven by an urgent need for global collaboration to provide trustworthy and living covid-19 guidance. A standing international panel of content experts, patients, clinicians, and methodologists, free from relevant conflicts of interest, produce recommendations for clinical practice. The panel follows standards, methods, processes, and platforms for trustworthy guideline development using the GRADE approach. We apply an individual patient perspective while considering contextual factors (that is, resources, feasibility, acceptability, equity) for countries and healthcare systems.The evidenceA living systematic review and network meta-analysis, supported by a prospective meta-analysis, with data from eight randomised trials (7184 participants) found that systemic corticosteroids probably reduce 28 day mortality in patients with critical covid-19 (moderate certainty evidence; 87 fewer deaths per 1000 patients (95% confidence interval 124 fewer to 41 fewer)), and also in those with severe disease (moderate certainty evidence; 67 fewer deaths per 1000 patients (100 fewer to 27 fewer)). In contrast, systemic corticosteroids may increase the risk of death in patients without severe covid-19 (low certainty evidence; absolute effect estimate 39 more per 1000 patients, (12 fewer to 107 more)). Systemic corticosteroids probably reduce the need for invasive mechanical ventilation, and harms are likely to be minor (indirect evidence).Understanding the recommendationsThe panel made a strong recommendation for use of corticosteroids in severe and critical covid-19 because there is a lower risk of death among people treated with systemic corticosteroids (moderate certainty evidence), and they believe that all or almost all fully informed patients with severe and critical covid-19 would choose this treatment. In contrast, the panel concluded that patients with non-severe covid-19 would decline this treatment because they would be unlikely to benefit and may be harmed. Moreover, taking both a public health and a patient perspective, the panel warned that indiscriminate use of any therapy for covid-19 would potentially rapidly deplete global resources and deprive patients who may benefit from it most as potentially lifesaving therapy.UpdatesThis is a living guideline. Work is under way to evaluate other interventions. New recommendations will be published as updates to this guideline.Readers noteThis is version 1 of the living guideline, published on 4 September (BMJ 2020;370:m3379) version 1.

Clinical question What is the role of drugs in preventing covid-19? Why does this matter? There is widespread interest in whether drug interventions can be used for the prevention of covid-19, but there is uncertainty about which drugs, if any, are effective. The first version of this living guideline focuses on the evidence for hydroxychloroquine. Subsequent updates will cover other drugs being investigated for their role in the prevention of covid-19. Recommendation The guideline development panel made a strong recommendation against the use of hydroxychloroquine for individuals who do not have covid-19 (high certainty). How this guideline was created This living guideline is from the World Health Organization (WHO) and provides up to date covid-19 guidance to inform policy and practice worldwide. Magic Evidence Ecosystem Foundation (MAGIC) provided methodological support. A living systematic review with network analysis informed the recommendations. An international guideline development panel of content experts, clinicians, patients, an ethicist and methodologists produced recommendations following standards for trustworthy guideline development using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Understanding the new recommendation The linked systematic review and network meta-analysis (6 trials and 6059 participants) found that hydroxychloroquine had a small or no effect on mortality and admission to hospital (high certainty evidence). There was a small or no effect on laboratory confirmed SARS-CoV-2 infection (moderate certainty evidence) but probably increased adverse events leading to discontinuation (moderate certainty evidence). The panel judged that almost all people would not consider this drug worthwhile. In addition, the panel decided that contextual factors such as resources, feasibility, acceptability, and equity for countries and healthcare systems were unlikely to alter the recommendation. The panel considers that this drug is no longer a research priority and that resources should rather be oriented to evaluate other more promising drugs to prevent covid-19. Updates This is a living guideline. New recommendations will be published in this article and signposted by update notices to this guideline. Readers note This is the first version of the living guideline for drugs to prevent covid-19. It complements the WHO living guideline on drugs to treat covid-19.

Despite efforts to use culturally appropriate, understandable terms for sexual behavior in HIV prevention trials, the way in which participants interpret questions is underinvestigated and not well understood. We present findings from qualitative interviews with 88 women in South Africa, Uganda, and Zimbabwe who had previously participated in an HIV prevention trial. Findings suggested that participants may have misinterpreted questions pertaining to penile–anal intercourse (PAI) to refer to vaginal sex from behind and subsequently misreported the behavior. Three key issues emerge from these findings: first, the underreporting of socially stigmatized sexual behaviors due to social desirability bias; second, the inaccurate reporting of sexual behaviors due to miscomprehension of research terms; and third, the ambiguity in vernacular terms for sexual behavior and lack of acceptable terms for PAI in some languages. These findings highlight methodological challenges around developing clear and unambiguous definitions for sexual behaviors, with implications not only for clinical trials but also for clinical practice and sexual risk assessment. We discuss the challenges in collecting accurate and reliable data on heterosexual PAI in Africa and make recommendations for improved data collection on sensitive behaviors.
Despite significant progress in paediatric HIV treatment, optimal antiretroviral formulations for infants, children and adolescents remain limited. The paediatric antiretroviral drug optimization group regularly reviews medium-and long-term priorities for antiretroviral drug development, to guide industry and other stakeholders on formulations most needed for low-and middle-income countries. Ongoing medium-term priorities include a scored dispersible dolutegravir tablet (10mg), a dolutegravir-containing fixed-dose combination, and fixed-dose combinations containing tenofovir alafenamide. Darunavir/ritonavir combination tablet remain a priority for second-line treatment. Future treatment options of potential interest for paediatrics include broadly neutralizing antibodies, long acting/extended release formulations, and novel technologies. Issues specific to neonatal prophylaxis and treatment, and to the investigation of novel antiretrovirals in adolescents and pregnant and lactating women are also discussed. Continued focus on identifying, prioritizing and ensuring access to optimal formulations suitable for infants, children and adolescents is key to ensuring that global HIV treatment targets can be met.
Introduction The unexpected identification of a neural tube defect (NTD) safety signal with preconception dolutegravir (DTG) exposure in the Botswana Tsepamo birth outcomes study brought into sharp focus the need for reliable data on use of new antiretrovirals in pregnancy, improved pharmacovigilance systems to evaluate safety of new drugs being introduced into populations including women of reproductive potential, and balanced risk‐benefit messaging when a safety signal is identified. Discussion The Tsepamo study NTD safety signal and accompanying regulatory responses led to uncertainty about the most appropriate approach to DTG use among women of reproductive potential, affecting global DTG roll‐out plans, and limiting DTG use in adolescent girls and women. It also revealed a tension between a public health approach to antiretroviral treatment (ART) and individual choice, and highlighted difficulties interpreting and messaging an unexpected safety signal with uncertainty about risk. This difficulty was compounded by the lack of high‐quality data on pregnancy outcomes from women receiving ART outside the Tsepamo surveillance sites and countries other than Botswana, resulting in a prolonged period of uncertainty while data on additional exposures are evaluated to refute or confirm the initial safety signal. We discuss principles for evaluating and introducing new drugs in the general population that would ensure collection of appropriate data to inform drug safety in adolescent girls and women of reproductive potential and minimize confusion about drug use in this population when a safety signal is identified. Conclusions The response to a signal suggesting a possible safety risk for a drug used in pregnancy or among women who may become pregnant needs to be rapid and comprehensive. It requires the existence of appropriately designed surveillance systems with broad population coverage; data analyses that examine risk‐benefit trade‐offs in a variety of contexts; guidance to transform this risk‐benefit balance into effective and agreed‐upon policy; involvement of the affected community and other key stakeholders; and a communication plan for all levels of knowledge and complexity. Implementation of this proposed framework for responding to safety signals is needed to ensure that any drug used in pregnancy can be rapidly and appropriately evaluated should a serious safety alert arise.
