Response from Dr. Sherer

While most patients achieve an undetectable viral load after 4 months, some take longer, 6 months or more, and those that require more time are those with the highest baseline viral loads, e.g. >100,000. So it is not unusual that you did not achieve full suppression after 4 months.
Your last two viral load values, both the absolute number and the log value, were the same, i.e. you did NOT experience a meaningful or significant increase from one value to the next. A real change by log value is a > 0.3 log change, or a >3x change in the absolute value of the viral load. You did not have either of those, so the two last values were essentially the same.
Still, as you suggest, it is disappointing that there was not a further decline to an undetectable level. With the regimen you are taking, >80% of patients achieve a viral load below detection after 6 months, even among those with a high baseline viral load.
The very positive response in your CD4 cell count and the excellent decline of almost 2 logs suggests that your regimen is working for you, and that you will continue to decline to below detection soon. You and your doctor can also look back at the resistance test to be sure that there were no other resistance mutations that might impair the activity of either Truvada or Kaletra.
I suggest that you talk to your doctor about your concerns, and take a copy of these observations with you.
