I'm glad to hear that he is being seen at a university hospital. It's good to be hopeful about his future health.

I hope that remission is a possibility for him in the future.

Here is some information from the Myositis Association. If you read the article, it does state that remission is possible. Here is a quote from the article,

"Antisynthetase syndrome can go into remission, especially for those with milder lung disease, but patients are more likely to remain symptom-free while continuing treatment. Flares tend to occur when medications are tapered too rapidly."

I would appreciate learning more about this disorder and your husband's response to the treatments. Will you continue to post updates?
