Proteinurea a real risk with Tenofovir

Besides interfering with mitochondrial DNA synthesis the tenofovir in the Truvada that a lot of us take, carries the risk of proteinuria; the consequences of which have yet to be firmly elucidated. Unfortunately there is no perfect drug.

Proteinuria a Risk With Tenofovir, Study Confirms
   
 
NEW YORK (Reuters Health) Aug 15 - Proteinuria occurs in roughly one quarter of HIV-infected patients taking the antiretroviral tenofovir and the odds increase with cumulative exposure to the drug and concomitant protease inhibitor therapy. In most cases, proteinuria subsides when tenofovir is stopped.

The observations of Dr. Mark D. Kelly and colleagues at Brisbane Sexual Health and HIV Service, Queensland, Australia, confirm and extend prior studies on tenofovir and proteinuria.

While proteinuria is known to be associated with tenofovir therapy, the prevalence, predictors and outcomes of those who develop it are not well described, Dr. Kelly and colleagues say in a Research Letter online August 7 in the journal AIDS.

At the Brisbane clinic, all patients are screened for proteinuria annually. This is performed by calculating the protein:creatinine ratio on a random urine specimen.

When Dr. Kelly and colleagues retrospectively reviewed the medical records of 153 HIV-infected patients who received tenofovir for more than one year, they found that 47 (27%) had proteinuria.........

Would be interesting to see if there was anything else linked to the proteinuria in this 27%.

It begs the question, why did 73% not have any proteinuria?

Case notes of 153 patients is not enough to estalish either cause or effect. The phenomenon is well known already, but 25% WTF! Getting % like this after many years of tenofovir use suggests your science is rubbish. The mitchondrial toxicity assertion is dubious too, very dubious given that the test tube studies demonstrating this effect used very much higher doses than will ever be achieved in your body if taking this med.
