Should meds be NOW considered? (WHEN TO BEGIN TREATMENT)
Dec 26, 2008
Hello Dr. Bob.. Happy Holidays.. and may your coming year be as bright as a shining star.. I recently did my labs on received my results..CD4..453 and viral load 44,000. I have some minor discomfort such as swollen lymph nodes in the groin area and infrequent joint pains in elbow and knees. Do u recommend and consider the start of ARV treatment? Please give me your feedback because I am getting worried whether my immune system is rapidly degenerating.

The optimal time to begin antiretroviral therapy remains a hotly debated topic as we learn more about HIV pathogenesis and natural history and develop new, more potent, less toxic medications. I'll try to give you an update on where things stand at the moment, but I would strongly suggest you discuss your situation with your HIV physician specialist, as there are many variables that must be taken into consideration for each individual situation. There is no one right answer for everyone. When it comes to beginning antiretroviral therapy it's a case of "one size fits one!"
A new study presented at the recent AIDS meetings in Washington, D.C. suggested HIV-positive folks should begin antiretroviral therapy sooner than the guidelines currently recommend (CD4 count of 350). The large study found that delaying the start of treatment until the CD4 count falls to 350 nearly doubles the risk of death during the next few years when compared to the risk of death in patients who began treatment earlier (CD4 count under 500). The survival benefit, however, must be weighed against the chances of drug toxicities and side effects. There is also the risk that poor regimen adherence could breed a drug-resistant strain of virus. There are, however, now three recent studies all showing that HIV-positive folks who begin antiretrovirals while CD4 counts are above 350 have a better chance of their counts returning to the normal range (600-1,200) than those who delay treatment until the CD4 count falls below 350.
Personally, as an immunologist, I strongly recommend early intervention with antiretrovirals if the person is ready, willing and motivated to begin taking the medications.
I should also mention there are situations in which we currently start antiretroviral therapy immediately despite CD4 cell counts. These conditions include patients with concurrent hepatitis and certain types of kidney disease and those who are pregnant.
Ultimately, I'm confident there will come a day when any HIV positive patient diagnosed will be advised to begin antiretroviral therapy as soon as they are diagnosed. This year we've seen treatment guidelines for beginning antiretrovirals increase from a CD4 count of 200 to 350. I think it's likely that this trend will continue with a formal recommendation to consider treatment at a CD4 count of 500 in the near future. Stay tuned to The Body. We'll keep you posted as the guidelines are revised. My personal recommendation is to begin antiretroviral therapy as early as possible in most situations, being fully cognizant that there are risks involved and that our scientific knowledge is still incomplete.
Hope that helps.
