Hi Dr Bob,
Three weeks ago I came down with Shingles. A small patch on the back of my neck and a little across my chest all on the left side. I went to my local GP and he gave me Valtrex ( the 7 day shingle pack)Since then the pain has gone and the Shingles have crusted over ...yet are still present albeit not as visible. Ive been POZ since 20th july 2007 and am NOT ON HAART....do you think having Shingles is a sign that my CD4T cells have fallen below 500???
I have a meeting with my HIV Dr in 1 months time for my usual LABS (cd4 & viral load) Do you think if my CD4 T cells have fallen below 500( even though experts say below 350) i should start treatment?
Also im seeing dark circles appear under my eyes...Im 33 yrs old ..is this simply age related or Low CD4 T cells and high viral load?? I drink plenty of water and have no family background of "dark circles /bags " under eyes...maybe its AGE ..aaarrrggghh And Mardi Gras is only a few weeks away...HELP!?!?!

G'day Aussie Drew,
Relax mate! Approximately 95% of healthy adults are seropositive for varicella zoster virus (VZV), the virus that causes shingles. Of this 95%, about 5% of healthy adults develop zoster (shingles). The risk for those of us with HIV is between 15 and 25 times greater. However, getting shingles (unlike many opportunistic infections) does not correlate with CD4 counts.
As for what your next CD4 count and/or HIV plasma viral load will be, I really have no way of predicting. (I don't know what your previous counts have been.) It's a good idea to wait a month or so after an intercurrent infection (like shingles) before checking your counts, because viral loads may well rise transiently and CD4 counts fall transiently as a consequence of any infection.
As for the optimal time to begin antiretrovirals, having just returned from the HIV/AIDS meetings in Montreal, I can advise you this topic continues to stimulate lively debate among HIV specialists. Recent studies, such as the North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD), which included more than 8,000 patients from 22 North American prospective clinical cohorts, are designed to answer the question of when to start therapy. The investigators in this study found a 70% greater mortality in patients who deferred beginning treatment until their counts dropped to 350 compared to those who started treatment with counts between 350 and 500. This study was an "observational" cohort study and therefore there is the possibility of selection bias, etc. However, the results are certainly intriguing. It's also worth noting there are now several other studies that have also found lower mortality, morbidity, drug toxicity and/or improved CD4 counts with initiation of antiretroviral therapy at CD4 counts above 350. Current guidelines, as you mention, recommend treatment for all patients with CD4 counts below 350. However, with results of large studies suggesting earlier treatment is better coupled with the recent approval of new and novel antiretroviral therapies which appear to be better tolerated, less toxic, more convenient and less risky if adherence is not perfect, the treatment pendulum certainly seems to be swinging back in the direction of early intervention. Personally, I encourage earlier intervention if the HIVer is willing and motivated to begin. Ultimately, I think we'll be discussing "when not to start" rather than "when to start" treatment.
Would I recommend treatment if your counts are 500 or less at your next blood draw? I certainly would discuss the option of starting with you to ascertain if indeed you were ready, willing and motivated to do so. If so, yes, I'd recommend you start.
As for the dark circles, no, that's not HIV related. You've just probably had too many Fosters at the pub plus too many late nights at the Midnight Shift.
Enjoy Mardi Gras, Drew. I've got plenty of fond memories of the many Sydney Mardi Gras that I attended! I've even toyed with the idea of heading to Oz for this year's party as well. (Save me a dance, OK?)
