Cosentyx for psoriatic arthritis Fred's journey

[Caroline]

I've read that the body can develop antibodies to the biologics, but it takes a few years. DMF is yet to lose any efficacy for me.

Cheers,

Bill

Interesting, I'm guessing that is what has happened as Stelara has been gradually tailing off.

If I am interpreting Bill's sentence, I think I understand that Bill says that his DMF still works without hesitation.
If I than read the answer of Fred, then it seems as if he compares it with his Stelara that was slowly losing it efficacy.
So in my humble opinion, either you don't understand each other, your speak different types of english, your english is not good enough, or....... I totally don't understand anything of what you both are trying to say.
