A “Morning Before” Pill to Prevent HIV Infection

In the next tenner , people may begin taking HIV medicine to prevent contract the AIDS computer virus , much the same way masses take malaria oral contraceptive pill . A middling odd discipline of macaques done by a group of researchers with the CDC demonstrated that two anti - retroviral medications , Emtricitabine and Tenofovir , were relatively successful at stopping HIV - like infection in the monkeys . This is expectant news if it turn out to form in mankind . The weird part was how the researchers prefer to exhibit the macaque to the disease . Let ’s say they really go for reality .

Each macaque was exposed “ rectally ” to the virus , repeatedly over a series of weeks . A release about the study said :

To simulate a vernacular route of HIV infection in humans , the researchers expose the macaques to low weekly doses of [ HIV - esque virus ] SHIV that were given rectally . Five groups of macaque were all expose to the virus in the same way , but they were given unlike dosages and combination of antiretroviral drugs . Three groups received drugs day by day : the first was only inject with one anti - HIV drug , emtricitabine ( FTC ) ; the second mathematical group received a day-by-day dose of this drug by mouth in combination with an unwritten class of another anti - HIV drug called tenofovir ; the third was throw in with FTC and a eminent acid of tenofovir every day . A fourth radical was also injected with FTC and a gamey pane of tenofovir , but macaques in this radical were only plow shortly before and after the weekly exposures to HIV . For comparison a 5th radical of macaques find no anti - HIV drugs .

The results showed that macaques from any of the four radical that receive drugs were less probable to become infected than those in the 5th ( ascendancy ) group . All of the macaques receiving the compounding of both FTC and the high dose of tenofovir were protected from infection — whether they were from the group that received these drug daily , or only around the fourth dimension of exposure to infection . The outcome suggest that gamey doses and combination of drugs work well than single or low doses , and also that PrEP may not take to be taken every Clarence Day to be effective .

I understand the motivation to reanimate the circumstances beleaguer HIV transmittance in man . But is n’t it just as likely that a human might get HIV from a dirty needle or blood transfusion ? Plus , anal sexual practice is n’t the only direction HIV is transmitted — in Africa , where AIDS is a far more devastating job than in the West , it ’s channelise from phallus - in - vagina sex activity .

I guess the investigator in this study really wanted to centre on forbid the cattle ranch of HIV via anal sex . bonnie enough . multitude who think they might be at risk for contracting HIV through sex could go on a course of action of Emtricitabine or Tenofovir and care less about wrapping themselves in layers of latex . I ca n’t await for the 24-hour interval when clinic in San Francisco have jumbo candy saucer full of HIV drug next to the glistening tray of condoms . Image byrselph .
