Here's what is posted on the Microscopic Colitis Foundation website, regarding LDN:

Some cases are unresponsive to conventional treatments. There can be many reasons for this, but it can be especially problematic when additional autoimmune (AI) diseases are present. There doesn't seem to be any medical research available to either support or disprove this observation, but epidemiological evidence appears to suggest that in cases where various conventional treatments have been tried without success, there is a possibility that one or more issues associated with other AI diseases may be preventing remission of MC symptoms.
Low dose naltrexone
In situations such as this, some patients have been able to resolve their MC symptoms by the use of low-dose naltrexone (LDN). While still in the experimental stages, and not yet accepted by most mainstream medical practitioners, treatments using LDN have established a surprisingly good success rate among many AI diseases that are otherwise refractory to treatment.
This is an off-label treatment for naltrexone, using doses that are only a small fraction of the amount normally prescribed for it's labeled uses. But if taken properly, it is said to reset the immune system nightly, resulting in the suppression of autoimmune-induced inflammation. Since LDN does not appear to be effective for patients who have only MC (and no additional AI diseases), and yet it does seem to be effective at relieving MC symptoms for many patients who also have other AI diseases, it seems likely that LDN may be capable of resolving MC symptoms by virtue of effectively treating other AI issues (other than MC) that have been preventing the remission of MC symptoms, despite a treatment program that would normally be expected to resolve the MC symptoms.
Currently, there aren't enough people who have tried it (who are members here) to allow a respectable number of responses to a poll, but we will probably try a poll at some point in the future, after enough people have tried it so that a poll might provide some meaningful results.
