U.S. anti-AIDS drugs were a major breakthrough in the risk of infection to drop gay
Global Times special correspondent Li Xue reported according to the U.S. "Business Week" on November 23 reported that researchers at the University of California, a recent "New England Journal of Medicine," published the latest results of a study, the results show that the world's largest AIDS drug manufacturers Gilead Sciences, Inc. production of a conventional tablet Truvada, to help prevent infection in homosexual or bisexual men, HIV, AIDS is no longer the end of a dream. Analysts pointed out that this kind of pills will increase the company of $ 1,000,000,000.
44% lower risk of HIV infection
The researchers tracked Peru, Ecuador, South Africa, Brazil, Thailand and the United States and other six countries tested negative for AIDS 2499 men, their ages ranging from 18 to 67 years old. Take the test need to take anti-AIDS drugs for 14 months, monthly access to condoms, sexual security consulting services, AIDS and other sexually transmitted diseases testing.
Studies have shown that inhibition of 2004 as the spread of the virus have been infected with AIDS drugs, Truvada can be 44% lower risk of HIV. University of California, who led the study Gladstone Institute of Virology and Immunology, Associate Professor, Robert - Grant, said that those who regularly take Truvada drugs, their risk of new HIV infections can be reduced by 73%. While 91% of new infections in the blood there is no such medicines.
This study is the third time over the past 14 months, testing for HIV prevention, AIDS has greatly increased the beating of human hope. Prior to that, although the medical profession has been a decades-long efforts, but until now still not developed an effective vaccine. In addition, there are eight research is evaluating the drug's safety and efficacy, as well as the drug is suitable for heterosexuals and drug users to prevent AIDS.
The end of AIDS is no longer a dream
Center for Disease Control and Prevention predicted that, after the announcement of the results of this study, many men will immediately ask for Truvada. But the agency noted that condoms prevent HIV infection is still the most effective way, and Truvada has not yet been approved for the prevention of AIDS drug use. National Institute of Allergy and Infectious Diseases Director Anthony - Fauci also said the data is impressive, there will be more and more people require such medication.
New York-based AIDS Vaccine Advocacy Coalition executive director Mitchell - Warren said: "The end of AIDS is no longer a dream, but in my eyes. We have a counter weapon AIDS plague." Obama said in a statement: "HIV prevention research breakthrough that I am encouraged, although much work to do, but these studies mark the beginning of a new era of AIDS prevention."
Kevin Washington, DC, AIDS Center - Fenton said that this was a major breakthrough, but for those gay men, now is not the time to abandon condoms. UNAIDS chief technology officer Gate - Hankins said, the test results are lower than we hoped, but has been very encouraging.
22 UNAIDS said in a report released in 2009, 180 million people worldwide died of AIDS infection. WHO data also show that more than tuberculosis and malaria, AIDS has become the most deadly infectious diseases.
Efficacy and risk must be tested in practice
Deutsche Bank Securities analyst Robin said that the effectiveness and risks of this drug should be tested in practice, including the long-term use would affect the patient's kidney, will lead to other side effects, or lead to drug resistance. Currently, no reports of resistance phenomenon. However, the test men taking Truvada the first four weeks, there will be nausea reaction, and weight will be reduced.
In addition, the study raised another issue is that the Government and insurance companies are willing for this to pay for drugs to prevent HIV infection. Through the health care system, Truvada 5000-7000 U.S. dollars per year, the private purchase may cost more. The money is beyond the capacity of some people. Kevin Washington, DC, AIDS Center - Fenton said they were preliminary discussions with the insurance company, seek to develop a reasonable plan.
