Burrill Bernard Crohn published paper was "Regional Ileitis: A Pathologic and Clinical Entity". Crohn's work helped correct the thinking that the ailment was actually a form of tuberculosis rather than an inflammatory disease of the gastrointestinal tract. Crohn's work built on the work of Dr. Kennedy Dalziel of Glasgow into regional enteritis twenty years earlier. Crohn always preferred the medically descriptive terms "regional ileitis" and "regional enteritis" to "Crohn's disease", but he was not able to prevent the appropriation of his name for the disease. Some of Crohn's initial research into the causes of the Crohn's disease was centered around his personal conviction
Chronic granulomatous disease from the name of the disease as children survived into adulthood. Gene therapy is currently being studied as a possible treatment for chronic granulomatous disease. CGD is well-suited for gene therapy since it is caused by a mutation in single gene which only affects one body system (the hematopoietic system). Viruses have been used to deliver a normal gp91 gene to rats with a mutation in this gene, and subsequently the phagocytes in these rats were able to produce oxygen radicals. In 2006, two human patients with X-linked chronic granulomatous disease underwent gene therapy and blood cell precursor stem cell
