Hiv And The Immune System
HIV: Hiv is the disease that destroys cd4 helper t-cells in our body. Aids is the final stage when HIV has won and overwhelmed the immune system. There are so many good treatments, you must see your infectious disease specialist to be placed on appropriate HIV therapy. ...Read moreSee 2 more doctor answers
Hiv infection is caused by a retrovirus....This retrovirus binds to CD4 cells (for the most part). You may detect the virus by several different methods. An elisa test (enzyme linked immunosorbent assay). You may also detect it by doing a test referred to as a western blot (a gel protein electrophoresis). Thirdly by pcr (polymerase chain reaction) which ...Read more
Yes: Very much so. During the acute illness, CD4 levels have dropped so low that quite a few people have gotten pneumocystis. Happily, they bounce back and hopefully the illness can be managed. Now why are you asking? I hope all's well. Your physician can help you if you're worried about having become infected, and I hope you'll be safe and not end up at risk. ...Read more
Does HIV evading the immune system support the idea of an evolutionary race between pathogens and hosts?
What are you asking?: WHEN you get infected by HIV? Hopefully, this will NEVER happen. You mean IF, correct? And the answer is, "Yes"; during the acute illness your T-cells will drop precipitously, then rebound. It sounds as it you need to talk with a reality-focused physician. If you are in a relationship with someone who is HIV+, you can be protected. ...Read more
HIV treatment: There are numerous classes of anti-retrovirals to treat HIV/AIDS. Their mechanisms of action are different, but the end result is the same. They all act to decrease viral replication, causing a decrease in the viral load in the blood as well as a gradual increase in the CD4 - T helper - cells. This helps to boost back the immune system. ...Read more
Hiding inside cells: The HIV is able to avoid the immune system because of its ability to hide inside the cells. The antibodies your body makes to prevent future infections cannot enter the cells, thus they are useless once the HIV is already inside. While inside, they can multiply and thus continue to cause disease for years. So, the best treatment we have =prevention. Live well, evangelineli1. Good luck. ...Read more
HIV: In a nutshell, attacks the T lymphocytes, one important white blood cell type, considered the master of the immune system, which also has many subtypes e.g.T helper cells, T suppressor cells, etc.., the virus attacks mainly the T helper cells thus disrupting the whole defense system, hope that helps ...Read more
Immune system attack: Good evening, it is an insightful question! HIV agent attacks the immune cells themselves while most other infectious agents are attacked by cells of immune system as soon as they enter our body. Hiv enters the immune cells, kills them, causes programmed cell death of cells, and we lose cell-mediated immunity. This makes us defenseless against other invading organism and normally harmless germs. ...Read more
HIV window period : Most people develop HIV antibodies within 2-8 weeks of their infection. The average is 25 days. 97% of people will develop detectable antibodies in the first 3 months. Rarely, it can take up to 6 months to develop antibody. If there's concern about acute hiv, a test that measures HIV RNA viral load can be done. The time between HIV infection and RNA detection is about 10 days. Talk with md. ...Read more
Human immunodeficiency virus (HIV) is a lentivirus (a member of the retrovirus family) that causes acquired immunodeficiency syndrome (aids),  a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections ...Read more
