Welcome back to the Forum Chris.  I remember our interchange as well as your earlier interaction with Dr. Handsfield.  The answers to your questions have not changes and I suggest you re-read your earlier posts rather than spending your hard earned money asking repetitive questions.  I say this because the answers will not change.  The official CDC and WHO recommendations remain that PEP follow-up testing should be done out to three months after completion of PEP.  As I explained, our belief is that these recommendations are overly conservative and we have complete faith that you did not get HIV from the event you described involving a needle stick with a needle used by a drug user but for whom you did not know if the person had HIV or not.  In fact, I have copied one of the statements I made to your earlier questions into this response.  It said- "Your chances of having contracted HIV are infinitesimal.  The RECOMMENDATION from the CDC and World Health Organization is that you should have a repeat test at three months.  This recommendation is likely to be overly conservative but that doesn't change the FACT that today that is the recommendation.  If I had a million dollars to bet, I would not hesitate to bet that any further follow-up tests related to the possible exposure you describe will be negative."  that is still my belief and your six week results only reinforce what I (and Dr. Handsfield) have already said.

There have been many studies of the risk of getting HIV following a needle stick from an infected person.  Estimates are, IF THE PERSON IS KNOWN TO BE INFECTED, are between one in 300 and 1 in a thousand (ie. between 0.3% and 0.1%).  As I understand it, you do not know that the person who had used the needle you were stuck with had HIV making the risk much lower, even before you took the PEP and with PEP the risk is lower still.  At this point, you are far more likely to be struck by lightening than to get HIV from the needle stick you have described. 

Reading through both this and your earlier questions however, I worry that about the psychological trauma of this exposure to you and wonder if yu have spoken with anyone about these concerns.  With all due respect, my sense is that you are having a lot of trouble moving forward from this event and could use a little bit of help by talking this through with someone.  I say this out of concern for you, not for any other reason.

Chris.  Your questions are repetitive and you do not appear to be hearing anything that I have said in this or prior threads.  Please read my reply above, as well as my earlier reply.  Your question was answered.

This is my third reply to your questions.  As a result this thread will be closed shortly.  EWH
