It's not completely implemented just now. The upfame/downfame you see in someone's profile isn't accurate. I think they're all stuck at 322 downfame, and you can't see the upfame.
For the 38 fame you have, it's related, but I don't think the link is established just yet. The 38 fame you obtained is from the achievements in which you could see by clicking on the "Fame Notification" at the top.
