I'm the wife of a celiac diagnosed 8 years ago. He's doing great on the gluten free diet. I have 3 children, 12, 10 & 5. I had my 2 oldest tested for the antibodies (through blood test) and both were negative. No tests since then. My 10 year old now shows symptoms of psoriasis. It started on his scalp in August. Doctors first thought ringworm (yuck!) had the culture performed which takes weeks to grow. Then started the 8 week course of antibiotics. Throughout this time I also applied Elicon (leftover from my other son's mild exczema). That mild steroid was the only thing that would make these spots almost seem to heal. But after a few days of not using the Elicon, the spots would return to looking as they had before. Went back to the doc 6 weeks into treatment because my son now has more spots on his body. Doc now thinks psoriasis since it responded to the Elicon and he finally used the black light which showed no presence of ringworm (They glow under ultraviolet light)(Why didn't the first doc do this?!) . To me they don't look like the pictures I've seen of DH because his don't look fluid filled at all. Can DH be all over the body including scalp and penis? Or does anyone know about the relationship between celiac disease and psoriasis? Should I have blood tests performed again on all children even if they were initially negative?
