HIV and Corticosteroids

I've had a rough year.  It started with a bad chest cold that would not go away and was over treated with too many antiboitics and corticosteroids. I've had bad fatigue all year and haven't felt like myself. My question is this.  Back in July of 05 I met a girl at a bar.  We preformed oral sex on eachother with no protection and put a condom on while having sex but it broke.  3 months later I had a HIV test which was negative.  6 months later I had another HIV test which was also negative. Dure the past year I have had One oral corticosteroid, Adavair which is a coriticosteroid, Nasacort nose spray, and a Kenalog shot in September. All of the were given to me because of allergies. I've seen on some sites that corticosteroids could cause a false-negative reading on a HIV test. My last corticosteroid was in September of 05 and I was tested in January of 06.  Would these be able to effect my HIV test.  Do you know where I can find information on the effects of corticosteroids on HIV testing.  I feel like my good test results are no good because of this information.  Please Help.

You are one of many people who seem to believe (or worry) that other illnesses, medications, and so on can prevent accurate HIV testing.  Not true.  That includes corticosteroid therapy.  You can rely with absolute, unshakable certainty on your negative HIV test results.

Good luck--  HHH, MD

Even if you had gotten the virus from the single sexual encounter with a woman, a 4 month period of time passing since last taking immunity suppressing drugs I would think to provide sufficient time for HIV antibodies to develop to detectable levels. Even with the potent PEP regimens (viral suppression), I have read after 3 months from discontinuation of the drugs a test should be valid. And has often been noticed well before.
Testing at 3 months will be picking up those that are previously immunity suppressed from another disease, and always by 6 months. I think you are clean, I am sure our good Dr. will agree.

I have seen this interference with seroconversion suggested MANY TIMES, perhaps it was being presented as an extra precaution to influence extended testing. But the only 2 legitimate sources I can find do not present real evidence, and they are old. Sorry, if I have mislead anyone by stating this. Good thing we have a real doctor here to correct me.  


Delayed seroconversion has been associated with simultaneous exposure to hepatitis C in two cases (Ridzon)

"Our data suggest that zidovudine prophylaxis does not delay the development of HIV antibodies beyond 6 months.."

Perhaps a concern if you are an Asian monkey;

"The observation of this delayed infection in our model (~3 months later than in untreated controls) and recent human evidence (21) further support the need for adequate follow-up periods after PEP administration to monitor for delayed seroconversions."
