[Question #1172] Prednisone use affecting HIV Test 18 weeks after exposure

49 months ago
Dear Doctors,
I had a risky experience receiving an unprotected BJ from a CSW around 19 weeks ago.
Recently, more precisely last week, I have been diagnosed with Bell Palsys, which may be caused by HIV infection. This drove me very crazy.  After 4 days of 15 taking prednisone, I went to a Rapid Test  which gave me a Negative for HIV infection.
Checking the Forum, it wasn't clear if Prednisone would or not affect this result by such period of exposure. My dosage is 60mg/day due to my body weigh (around 125kg or 276lb). Can I believe in this result?
Thanks in Advance.

 Welcome to our forum. I will be happy to comment.   Indeed, HIV is on the long list of  infections which are associated with Bell's palsy. However HIV is a rare cause of Bell's palsy  and many cases of the syndrome have no obvious cause.   As you may know, no one has ever been proven to get HIV from receipt of oral sex  and I expect that your Bell's palsy is unrelated to your earlier encounter with a commercial sex worker.   I would have complete faith that the results of your recent rapid HIV test are reliable and indicate that you did not acquire infection from the encounter you described.   If you had acquired HIV 19 weeks ago your HIV test would certainly have been positive within eight weeks of exposure, long before you began taking prednisone.    Antibodies formed in response to an infection 19 weeks ago would still be present despite recently beginning prednisone and your test would still be positive,    You can certainly trust your test results. 

 I hope this information is helpful to you and that you were bells palsy resolves soon. EWH
