Nobody can predict the future. However, new antiretroviral drugs are constantly being developed -- some that belong to existing classes of drugs and some that belong to entirely new ones. As this guide is being written, a new class of drugs called integrase inhibitors is already available both for people who are starting treatment for the first time and for those who are "treatment experienced," and studies are looking at drugs from other classes as first-time options as well. The more options, the more alternatives to switch to down the road. Having entirely new classes to work with makes it much easier for people whose HIV is resistant to multiple drugs to build effective combinations.
Caution is needed with any new drug: Drug toxicities do not always show up right away and may only become apparent after people have been on medications for some time. There may be longer-term problems with integrase inhibitors and other newer meds that we will only become aware of in the future. This tends to divide people with HIV and their doctors into more conservative and more adventurous camps. Some prefer to stay with more "tried and true" drugs, despite the drugs' known shortcomings. Others are more willing to try out newer options that appear to be safe and effective in the short term, despite not knowing the possible long-term risks.
In addition to antiretroviral drugs, other forms of treatment are being studied as well:
So far, the results of studies of immune boosters and therapeutic vaccines have been disappointing. Some people hope that, one day, these sorts of treatments might delay the need for antiretroviral drugs, by keeping the immune system strong for a longer period of time. Most experts do not believe they will ever replace antiretroviral drugs. Only time and further study will tell whether this turns out to be the case.
HIV treatment information changes regularly. By the time you read this, there may be new information that could affect your treatment choices. In this guide, we have tried to focus less on particular antiretroviral drugs and more on ways to go about making decisions, which should stay reasonably constant over time.
When you're looking for information about current treatment options, always reach for the very latest information -- via treatment newsletters (CATIE publishes TreatmentUpdate and CATIE News), websites (check us out at www.catie.ca), your local AIDS service organization and, of course, your doctor and other healthcare providers. You can also call CATIE's information support line at 1-800-263-1638 to speak with one of CATIE's knowledgeable educators. They can answer your questions about the prevention and treatment of HIV and hepatitis C.
With that, we hope you'll make the best possible treatment decisions. We wish you good luck and long-lasting good health.
