Préparer les homosexuels à la prophylaxie pré-exposition

LONDRES – En octobre dernier, deux groupes de chercheurs menant des essais cliniques sur l’efficacité d’un médicament potentiellement révolutionnaire dans la lutte contre le VIH ont pris une décision inhabituelle. Ils ont annoncé que le traitement qu’ils testaient, au moyen d’un médicament antirétroviral appelé Truvada, s’était révélé suffisamment efficace pour mettre fin à la période d’essais cliniques randomisés et que ce médicament serait mis à la disposition de tous les participants à l’étude.

Les chercheurs ont découvert que les homosexuels qui prenaient régulièrement du Truvada, tout en utilisant des préservatifs lors des rapports sexuels, avaient beaucoup moins de chances de contracter le VIH. Ce fait confirme l’efficacité de la prophylaxie pré-exposition (PrEP) dont le principe consiste à proposer à des personnes non infectées d’utiliser des traitements antirétroviraux pour se protéger du risque de contracter le VIH. En 2011, un essai clinique mené par la Fondation Gates a montré que la prise de Truvada par les couples hétérosexuels réduisait de 73 pour cent le taux de transmission du VIH.

Les acteurs de la lutte contre la propagation du VIH/sida ont donc un nouvel outil à leur disposition. La question qui se pose maintenant est comment le mettre à la disposition de ceux qui en ont le plus besoin : les homosexuels des pays en développement.

    China in the Lead?

    For four decades, China has achieved unprecedented economic growth under a centralized, authoritarian political system, far outpacing growth in the Western liberal democracies. So, is Chinese President Xi Jinping right to double down on authoritarianism, and is the “China model” truly a viable rival to Western-style democratic capitalism?

    Whither the Multilateral Trading System?

    The global economy today is dominated by three major players – China, the EU, and the US – with roughly equal trading volumes and limited incentive to fight for the rules-based global trading system. With cooperation unlikely, the world should prepare itself for the erosion of the World Trade Organization.

    The Globalization of Our Discontent

    Globalization, which was supposed to benefit developed and developing countries alike, is now reviled almost everywhere, as the political backlash in Europe and the US has shown. The challenge is to minimize the risk that the backlash will intensify, and that starts by understanding – and avoiding – past mistakes.

    A Better British Story

    Despite all of the doom and gloom over the United Kingdom's impending withdrawal from the European Union, key manufacturing indicators are at their highest levels in four years, and the mood for investment may be improving. While parts of the UK are certainly weakening economically, others may finally be overcoming longstanding challenges.

    The UK’s Multilateral Trade Future

    With Brexit looming, the UK has no choice but to redesign its future trading relationships.
