D3 supplemets and Tenofovir-containing ART
Apr 27, 2011

Dear Nelson,

I had seroconversion illness about two years ago. I started meds, Isentress (2 tablets/d) + Truvada (1 tablet/d), 10 months ago No significant side effects, except for muscle and leg pain sometimes. My concern is about my kidneys (and my bones too). I was reading that there have been several case reports of kidney damage caused by Tenofovir. Also, asymptomatic renal tubule damage may affect people taking Tenofovir even if they have a normal glomerular filtration rate. In a recent presentation at CROI 2011 some researchers showed that Vit. D3 supplementation would increase tubular reabsorption of phosphate (TRP) and decrease serum parathyroid hormone (PTH). This mechanism is not clear to me but... does it mean that an increase of D3 vitamin could help to clean renal tubules for people on TDF-containing ART? Second, does taking ALSO calcium supplements (with D3) is safe to my kidneys? Thank you for your kind help, in any case.

Alex Tota
