High Trygs

Nov 16, 2011

Dear Dr McGovern

As a follow-up to your query about the lipids, the figures are:

12-2007 09-2008 10-2010* 02-2011* 05-2011 08-2011

Total Chol. 163 200 243 230 366 250 HDL Chol. 35 56 46 50 54 45 LDL Chol. 100 117 163 149 136 140 Trygs 100 133 172 210 255 355

10-2010 > Test done after adding Norvir to unboosted ATV 02-2011 > Test done after switching ATV/R to DRV/R

A major concern is the ever-increasing trygs. He eats healthy almost vegetarian diet and in very moderate quantities since decades ago. Questions are :

a) Which statin, if any, would add to regime ?

b) Would a switch back to ATV/r, despite minor biluremia, also be preferable to current DRV/r to help lower lipids ( besides the switch from Kivexa to Truvada )?



Temporary Meds Switch Sep 29, 2011

Dear Dr McGovern,

The patient's data: HIV+, CD4 600, VL hovering between UD and low viremia ( 50 to 100 ), mid-fifties, in good health. On meds. The current regime is : Darunavir/Norvir/Kivexa. Resistances : K65R, K103N,G190S. A previous regime, abandoned a year ago, was Reyataz/Norvir/Kivexa; it was similarly effective but switched just to get rid of minor biluremia. The new regime has, however, considerably raised lipids ( trygs & chol ).

The questions are : 1) A small stock of previous meds is left over. He does not wish to waste it by throwing it away. Would there be any negative consequence if one temporarily switches to the previous equally effective regime till the stock is exhausted to switch then back to the current one ?

2) Most of the previous meds have not expired yet, but a few bear the expiration date of 03/2010. Can the latter ones still be used ? ( btw : they have been kept in a refrigerator ).

3) He is considering switching next from Darunavir/Norvir to Etravirine to avoid current high lipids. A recent study presented at ICAAC 2011 has established such switch maintains efficacy and safety and lowers lipids. Further, a switch from Kivexa is also in order given that the patient's resistances render it only of intermediate efficay. The only fully effective option left in the NRTIs group is AZT but he wishes to avoid it on account of the anemia it causes. Given the said conditions, which other med(s) would you suggest to couple with etravirine to form a fully effective and safe regime ?

Your volunteer professional advisory assistance is greatly appreciated and you can be sure it has an enormous positive impact worldwide.


Response from Dr. McGowan Anthony,

Thanks for your questions:

1) No negative downside since the switch was not made for virologic failure, you may substitute one potent regimen for another.

2) Most drugs have adequate potency and safety even up to a few years after the posted expiration date (see: If they have been properly stored they should be safe to use, especially if cost is an issue. Keep a close eye on the viral load, especially if their will be an extended use of these.

3) Most studies show that changes in ART to help normalize the lipids are not very effective. How bad are the values? Would prefer a lipid lowering therapy if that is an option. G190S is a mutation taht can have some effect on etravirne susceptibility (carries a weighted score of 1.5, with decreased responses seen with 2.5 weight or higher). I agree that the kivexa may be contributing little and may be adding to the lipid abormality. Truvada may be the better option (keeping norvir and prezista at first), since tenofovir will be more lipid friendly than abacavir and tenofovir will maintain phenotypic susceptibility despite K65R alone. Also, the norvir/darunavir can be dosed once daily (100mg/800mg, if not done already) since their are no PI mutations. That will lower the ritonavir exposure and may help the lipids. If you really want to avoid the PIs altogether and Zidovudine, then you will need 3 new active drugs: etravirine, raltegravir and ....maraviroc (if tropism testing shows R5 tropic), or perhaps (but probably not) fuzeon. No other real options...can't use unboosted reyataz with etravirine due to the drug-drug interaction. I would try to work with the PI combo and add a statin.

Best, Joe

Response from Dr. McGowan


The trend of increasing triglycerides seems to have started before the switch in meds. In fact all of the parameters (HDL--good; LDL and total cholestrol) have trended up. The most worrisome (LDL) as far as risk for heart disease or stroke has actually stabilized a bit after the switch. It is importatnt that all of these tests have been done fasted (not eating for over at least 8 hours). The triglycerides should not be measured after eating.

Has there been any weight gain? This pattern can be seen in people who are recovering after a period of wasting.

I would put it into the context of his other risk factors for heart disease: does he have high blood pressure? high sugar (or diabetes)? any kidney problems? Does he smoke? any family history of heart attacks at a young age? If any of these are issues they may need to be addressed primarily, especially to stop smoking. The triglycerides would not need treatment at this level, but a review of diet and excercise routine should be done. I don't see any benefit in switching back to atazanavir.

Best, Joe
