may resond to dietary therapy alone. [[Gastroprotective Drugs|gastroprotectants]] such as sucralfate and cimetidine may be beneficial.
[[Steroids|corticosteroids]] can be used in moderate-severe cases as a means of immunomodulation.
**azathioprine may be used in conjunction with corticosteroids in cases that fail to respond to corticosteroids alone. The white cell count should be monitored from 2 weeks after the first dose and treatment should be stopped if the count falls to less than 4x10e9/L.
