Treatment for AIDS
- Anti-Retroviral Therapy:
- It is a combination of daily medications that stop the virus from reproducing.
- The therapy helps in protecting CD4 cells thus keeping the immune system strong enough to fight off the disease.
- It, besides reducing the risk of transmission of HIV, also helps in stopping its progression to AIDS (a spectrum of conditions caused by infection due to HIV).
- Stem Cell Transplant:
- Under this, an infected person is treated with stem cell transplant from donors carrying a genetic mutation that prevents expression of an HIV receptor CCR5.
- CCR5 is the most commonly used receptor by HIV-1. People who have mutated copies of CCR5 are resistant to HIV-1 virus strain.
- It has been reported that till now, only two people have been cured of HIV by experts using this method of treatment. The first person is Timothy Ray Brown (Berlin Patient) who was cured in 2007 and the second is known as London Patient, who just got cured of HIV.
- The difference in the treatment of both patients is that the Berlin Patient was given two transplants and he underwent total body irradiation while the London Patient received just one transplant and also less intensive chemotherapy.
- Researchers find this method very complicated, expensive and risky.
