Referral to nephrologist or
internist
< 60 cc/min* < 30 cc/min*
CaPO4 Renal ultrasound
* If GFR < 50 cc/min: consider adjusting the dose of certain ARV and concomitant medications
** Test for tubulopathy if GFR declines > 10 cc/min while on tenofovir

• Do you d/c metformin? • Do you d/c NSAIDs?
• Do you d/c statin?
• Do you Need to dose Adjust ARVs?
• Should you Change ARVs?
• Do you Hold Ace Inhibitor?
• Do you ensure BP/BS well controlled?
• Do Nothing?
Management Options?

• BP well controlled
• Hga1c 0.062, therefore Metformin stopped
• Asked not to take any NSAIDS
• ARV regimen continued at same doses
• Continued same dose of statin, ACEi
• Cr monitored closely in range of 118-130 (eGFR 55-60 range)
