<<Disclaimer: Verify this information before applying it to your situation.>> First, let me thank all of you who responded to my post regarding DH. Several of you indicated that my husband has a "severe" case. This thinking got the ball rolling. He has been seeing his new dermatologist every week for the past 4 weeks. He has had two more skin biopsies and today the new verdict came in. It appears when he was first diagnosed in July 1998 (which we have just found out that he never was officially diagnosed-his medical reports stated "could be DH") the pathology reports were conflicting. The first test showed positive for DH, the second test showed negative. The new dermatologist redid the biopsy on his leg and received the same report. Postive-Negative. Still not convinced, he again took a biopsy of a new blister from his arm. He sent this one to Vanderbilt University. He has now been diagnosed with Linear IgA disease. It is a fairly new disease-(first reported case in 1979). Dapsone is the treatment used but I am receiving conflicting reports as to the gluten free diet treatment. The dermatologist said to stay on the diet and continue the dapsone. He didn't have any info available but will have some sent from Vanderbilt. My question is: What is this disease? I haven't found any sites with information that has proven useful. Most just give medical terminology and treatment. I want to know what causes this condition, what is the outlook, is this curable or tolerable. Any information would be greatly appreciated. If you know of any on line groups for this, please let me know. Again, thanks for all of your information and support. BTW-his Dapsone dosage has been increased to 200 mg per day. Thank you, Jamie Knight
