Homoseksuele mannen moeten toegang krijgen tot PrEP

LONDEN – In oktober hebben twee groepen die de effectiviteit onderzoeken van een geneesmiddel dat een potentiële doorbraak zou kunnen betekenen in de strijd tegen HIV iets ongebruikelijks gedaan. Zij kondigden aan dat het middel dat ze aan het beproeven waren, een medicijn tegen retrovirussen genaamd Truvada, effectief genoeg was gebleken om een einde te kunnen maken aan de testfase met placebo's, zodat ze de pil aan alle deelnemers van de onderzoeken zouden gaan aanbieden.

De onderzoekers hadden ontdekt dat homoseksuele mannen die Truvada slikken, en condooms gebruiken als ze seks hebben, veel minder kans hebben om HIV op te lopen. Dit duidt op de effectiviteit van 'pre-exposure prophylaxis' (PrEP), een techniek waarbij mensen die HIV-negatief zijn middelen tegen retrovirussen gebruiken om zichzelf tegen een mogelijke infectie te beschermen. In 2011 bleek uit een proef die door de Gates Foundation werd gefinancierd dat heteroseksuele stellen die Truvada gebruiken het risico op besmetting met HIV met 73% konden verlagen.

Degenen die proberen de verspreiding van HIV en AIDS tegen te gaan hebben dus een nieuw wapen in hun arsenaal. De vraag is nu hoe ze dit wapen het beste ten goede kunnen laten komen aan degenen die het het hardst nodig hebben: homoseksuele mannen in de ontwikkelingslanden.

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
