VL and vaccines
Jan 10, 2003
How long after receiving a vaccination should i wait to get a vl test? I had a flu shot Nov 1st and Pneumonea and Hep A. shots on Dec 10th. Also, on Dec 10th my Dr. gave me 40 mg of prednisone per day for 10 days to help clear up a skin rash. Does prednisone effect any lab? Lastly, could my skin problems be MAC? I am taking azythromycin twice a week to keep from getting MAC but if I do have MAC now, is that profolactic dose doing more damage than good? I guess i biopsy of my rash should be done but recall seeing discussion or some concern of an accurate biopsy after receiving prednisone.
Response from Dr. Holodniy
Most people would recommend waiting at least 2 weeks, and probably 4 weeks after receiving a vaccination before getting a viral load and CD4 count. Prednisone might affect the CD4 count, either up or down. Since prednison is an immunosuppressant drug, it is usually not a good idea to biopsy skin when people are receiving it, because it could mask what is causing the skin reaction. I doubt the skin condition is related to MAC, but it could be related to a drug reaction from azithromycin or any other medication you are taking.
