Auto Nofollow attribute in custom field links. How?

Question

I have a wordpress network. All the contents in my network are user generated. All posts links are now dofollow. I want to change it to nofollow. My site uses plugin for custom fields. I removed the default description area. So i cannot use the_content function. I use custom fields for all.

I tried many auto nofollow plugins. But its not working in my custom fields. Can anyone help me?

Is there any function code available?

I just want

<a href="http://domain.com">My Link</a> 

to

<a href="http://domain.com" rel="nofollow">My Link</a> 

Thanks
