Not undetectable yet...
Mar 23, 2011
Hi Doc, I am starting to be worried cause I just got my results and not undetectable yet. here they go (after 6 weeks of Atripla treatment): Week 6: VL 100 copies (still not undetectable). CD4 306 & 22%. Triglicerydes 224 mg/dl. VLDL 44 mg/dl. Uric Acid 7.2 mg/dl. M.C.H.C. 35.1 g/dl. Week 4: VL 118 copies. CD4 276 & 21%. Triglicerydes 173 mg/dl. VLDL 34 mg/dl. Uric Acid 7.2 mg/dl. M.C.H.C. 34.1 g/dl. I started my treatment with a VL of 66,000 and CD4 of 250. I am worried that i am not undetectable yet. I take my Atripla always between 10pm and 12 (midnight). Never missed a dose. Should I start being concerned about treatment failure? I got a Genotype and no resistance detected. The tests were made with different test kits but same laboratory(first with <40 copies, second with a <20 copies. First with Abbot m2000 and second one with Cobas Taqman v2 Roche). Any advices please? Can I be still undetectable? what's the window period to achieve undetectable? THank you very much.

Assuming there was no baseline resistance then your experience is not all that unusual. There is typically a large initial drop in viral level which often flattens out for several months until reaches undetectable status. Some of the newer HIV RNA assays have some technical issues at low levels (including the Roche TaqMan assay) so that < 200 copies is commonly considered undetectable and you are already in that range which is good. Window to achieve undetectability with Atripla often 1-3 months unless HIV level > 100,000 at baseline in which case it many take 1-5/6 months. KH
