Did the vet mention how her teeth looked? FIV+ kitties notoriously have problems with gingivitis and their teeth. In fact, they really ought to go for dentals every 6 months.
Here are some links that may help you be able to discuss with your vet (though if your vet is calling it Feline AIDS and your kitty is not at the terminal stage, you may want to find another vet) treatment options:
This is an article about Bud (FIV+ kitty), to put Bud's FIV therapy into context:

Bud's Therapy (BTW, none of these supplements should be given without vet participation. If there is a holistic DVM in your area, you may want to investigate that route) :

There is a Yahoo Group for FIV+ Kitties:

Our FIV+ kitty, Chumley, is having problems being very itchy/scratchy. We thought we eliminated food triggers as a source of the apparent allergic reactions - though the vet cautioned these are usually environmental, not food related. We put him on the Hill's z/d diet. Turns out the dry z/d has Brewers Rice as its main ingredient, and this is a known allergan. So we've now got him on a wet-food only diet (for the past three days), as we're revisiting the food as a trigger.
In the meantime, a number of people have recommended extra virgin, cold pressed coconut oil (from fresh coconuts). It has antiviral, antibacterial, and antifungal properties in addition to antihistamine properties. It's also an anti-inflammatory. The brand Nutiva is available at most Walmarts. You can read about it here:

We're working on getting his intake up to 1 - 2 tablespoons a day. Unhydrogenated Coconut oil is like crisco (sort of) - he didn't like it mixed into his food just like that. But once I melt it, I'm able to mix it into his food and he eats it like normal. I started REALLY small, and have worked up to a teaspoon. But someone on the FIV Yahoo group have brought up questions about feeding cats plant fat (cats are carnivores and their digestive systems aren't really designed for it)... I'm really not sure what to think.
But I'm at the holistic vet we found in our area this Friday - first visit with our Chumley.
I just know I don't want to sit back and do nothing. I want to first and foremost solve this problem with what appear to be allergies (he isn't congested and doesn't have runny eyes - he's itching and scratching a lot, and has two small bare spots on his front legs). We were using zyrtec, which definitely lessened the amount of itching/scratching, but it seems to have flared up (thus we're back to the food elimination thing).
