Both eczema, dental inflammation (gingivitis/periodontitis) and exercise have all been shown to trigger hepciden release. in addition to having hepcidin tested you could also get you calprotectin tested to rule out intestinal involvement.
The patent for adulimumab (humira) expires in 2016 so hopefully competition wil bring the price down and make it more viable. I am in the very fortunate position of living in the UK where my consultant virtually gave me a menu of treatments to choose from. We have no concept of factoring cost in to these choices.
