Title: Bone mineral density test, phosphate deficiency and concern over Tenofovir
Post by: Jody on March 14, 2012, 01:57:51 pm
My doctor noted that I have a phosphorous level of 2.0 after it was 2.2 this past December.  A few years back he noted a one time level lower than the normal 2.5 as well.  So he wants me to have a blood and urine test at the lab for phosphorous excretion and a DEXA for a bone mineral density test at the radiologist.  My CD4 count went from 214 to 165 and the pct and ratio also dropped in three months from 17% and 0.45 to 13% and 0.33, perhaps just a blip.  His concern is phosphate wasting and possible bone issues of course.  He is concerned that perhaps the tenofovir in the Truvada I have been taking for a few years now as well as in Viread in my previous regimen may be the culprit.  Oddly I have had a slight pain in my right arm for a while now around the right elbow, I think it is more in the tendon than anything but will hope for the best.  This too shall pass.  Thanks for reading and I hope you are still awake. ;)

Hello Jody, I am awake, the tests seem sensible, hope you have options for when/in case you need to switch off tenofovir.

Thanks Matt, the doctor did say I had other regimen options for sure and none would need to include Fuzeon, thanks to the goddesses for that!  Thanks for your reply, you have imparted much wisdom to so many folks here over the years.

Hi, I was taken off of Viread after 5 years because my creatinine level was abnormally high (another indication of kidney function) & getting worse. After 8 months my creatinine came half way back down towards normal. Yes, there are many regimens that don't indude the tenofavir. I'm doing fine without it. I also saw a nephrologist & she said I don't need any meds or diet changes unless my creatinine level starts to go up again.
I would ask your doc, i thought if your kidneys weren't functioning that your blood  phosphorus level would get too high, not too low. Maybe it could go either too high or too low, neither one is good news. Best of luck. Hugs, Deibster

Hi Deibster, thanks for your response.  My creatinine level was normal at 1.03 and my kidney and liver numbers were in the normal range right now.

I got the results of my bone density test at the radiologist and the blood/urine tests at the lab.  My phosphorous level is 2.4, normal is 2.5 to 4.5.  My renal function is 0.97, considered good and the urine creatine is normal.  Regarding the bone test the spine was OK but the hip was a bit of a problem with the results: "based on the lowest T-score of -2.5 at the total right femur, this is considered osteoporotic, with a high risk of fracture".  I have never had a broken bone. 

So the doctor felt it best to alter my current regimen of Prezista, Norvir and Truvada and replace the Truvada with Isentress.  I will also add Oscal 500/Vitamin D  - 400 units and vitamin D3 -  2000 units daily and later add Fosomax.
