Hi, I am new to this forum, as my son was diagnosed with Crohn's of the stomach, duodenum, and cecum this May. He is on Pentasa, prilosec, vitamin d, iron (newly deficient), and a probiotic. He did 2 months of steroids over the summer which worked wonders. The daily vomiting stopped completely. In August his cal protectin was down from 650 to 70. Now its back up to 550, and he occasionally complains of stomach pain, but no vomiting. The np told me to be prepared with questions about Imuran/Remicade for our appt next week. Is this a necessary next step? I really dont want to use these drugs unless necessary and hes feeling ill routinely. Is this calprotectin level enough to base this treatment on? Any other parents with young kids have any advice??
