AIDS: to disable anti-drug control?

"Bible" forecast the end of last century will be a full human beings can not resist the new disease that is not only against humanity but also the destruction of all mankind. It is said that the disease is AIDS. It is true that the outbreak of AIDS 20 years, scientists have realized that invented the drug to cure the disease is still very little opportunities, the main reason is that all the integrated treatment of AIDS drugs have side effects, so that AIDS has become increasingly difficult to control. At present, the treatment of AIDS drugs a total of 15. Well-known AIDS scientist David Ho invented the drug cocktail is more successful drugs in recent years. There are side effects of the cocktail This therapy is the main carrier to reduce AIDS mortality and morbidity, but will not completely eradicate the virus from patients, and there is a serious, potentially fatal side effects. Although the AIDS virus HIV can avoid the rapid mutation of the drug, but at the same time in three or more types of anti-retroviral cocktail of drugs can be successfully controlled in many patients with HIV in the blood concentration and thus further reduce or prevent Many of the opportunistic infections. Some diseases such as pneumonia, tuberculosis and skin cancer, is ultimately lead to AIDS the leading cause of death. The cocktail, so that about 80% of AIDS patients can survive for at least 10 years or more. Prior to that, only about 55 percent of patients survive 10 years or more. Stop drugs HIV virus, the rapid rebound However, this success has been not a small price to pay. Some scientists pointed out that the cocktail will cause many side effects, including lipid malnutrition, back abnormal accumulation of abdominal fat, abnormal blood lipid levels increased, which is the most serious liver failure and diabetes. In addition, the scientists found, HIV virus in drug control, will be hidden in some organs. Once the role of the cessation of drug, HIV virus will rebound quickly. Studies have shown that even if the drug has the blood of patients in the control of the virus is almost impossible to detect the levels, HIV virus is still in some organs such as lymph nodes and reproductive tract to conduct the reproduce slowly. The role of drug cessation, HIV virus, the rapid rebound, but also brought another ray of hope for AIDS patients. A few years ago, the United States a doctor observed that one of his AIDS patients in the drug repeatedly, and eventually quit after treatment, their immune system has succeeded in maintaining the virus under control in the area, and lasted for over three years. This phenomenon is found, the medical profession started to look into the possible interruption of the treatment of the negative effect of the treatment. The early studies have shown repeatedly interrupted treatment can strengthen some of its own in patients with the HIV virus immunity.
