To the Editor,

A 32-year-old Japanese male presented to the emergency department with a history of diarrhea and high fever for four days. He had undergone living-donor kidney transplantation for unknown end-stage renal disease one year ago. He was a known case of complete visceral inversion. His immunosuppressive medications were methylprednisolone 2 mg, myco-phenolate mofetil 1000 mg, and extended-release tacrolimus (ER-TAC) 5 mg. Physical examination revealed no abdominal tenderness. His ascending colon was edematous on computed tomography. After three days, Campylobacter jejuni was detected on a blood culture. Intravenous ciprofloxacin 300 mg (b.i.d) was initiated. His renal function remained the same before and after diarrhea, with serum creatinine levels of 1.64 mg/dL. After treatment, the patient became afebrile, and diarrhea subsided. Therefore, we changed the route from intravenous to oral ciprofloxacin 500 mg (b.i.d) after one week.

The patient’s clinical course, including details about the TAC concentration, is shown in [Figure 1]. Before diarrhea, the TAC concentration was 5–8 ng/mL while the patient was taking ER-TAC 4.5–6.5 mg. At the time the patient developed diarrhea, the TAC concentration was very low (2.0 ng/mL) despite stable renal function. The patient had continued to take TAC as prescribed. At this point, the ER-TAC dose had to be 7 mg after concentration was attributable to Campylo-bacter colitis.

TAC is a key drug for renal transplant recipients, and the blood concentration is important to maintain. The TAC concentration is influenced by metabolism due to CYP3A4 of the small intestinal mucosa.[1] Diarrhea has been reported to be associated with an increase in TAC concentration.[2],[3] However, the TAC concentration does not increase in all patients with diarrhea. Clostridium difficile-associated colitis, which is a representative form of colitis, is not associated with an increase in the TAC concentration.[4] However, cryptosporidiosis, which is a representative form of enteritis, is associated with increased TAC levels and acute kidney injury.[5] Taken together, these previous reports indicate that an increased TAC concentration reflects drug metabolism in the small intestine. In the case presented here, a decreased TAC concentration was noted when the patient had diarrhea. The underlying mechanism is unclear; however, adherence as a potential cause was definitely ruled out. It is important to determine whether colitis or enteritis is the cause of diarrhea for adjusting TAC concentration in renal transplant recipients.

Informed consent was obtained from the patient before publishing the manuscript.

Conflict of interest: None declared.
