Acute colonic pseudo-obstruction caused by mycophenolate mofetil in a kidney transplant recipient

Mycophenolate mofetil is a component of immunosuppressive regimens in solid-organ transplant recipients. Gastrointestinal symptoms such as nausea, abdominal pain, and diarrhea without fever are common in patients treated with mycophenolate mofetil. We treated a patient who had acute colonic pseudo-obstruction after kidney transplant that resolved after discontinuing mycophenolate mofetil. The disorder recurred soon after resuming mycophenolate mofetil, which is evidence for an association between mycophenolate mofetil and acute colonic pseudo-obstruction in this patient.
