Treating DUPA with Dutasteride?

has there ever been a case in which somebody with DUPA (Diffuse Unpatterned Alopecia) has responded to dutasteride after trying propecia (finasteride)?

I have very little experience with Avodart (dutasteride), but I have seen some patients with Diffuse Unpatterned Alopecia (DUPA) respond somewhat to finasteride. In theory, dutasteride should be better than finasteride, but clearly the side effects are substantial with dutasteride (decreased sperm count, impotence, decreased libido). Unfortunately, we do not know a great deal about DUPA and what causes it.
