Abstract

Rotavirus enteritis (RVE) is increasingly recognized as a cause of small bowel allograft dysfunction but its significance in adult patients is unknown. We have studied 23 adult small bowel transplant patients aged 19.8-59 years (mean = 38.2 years), who were presented with diarrhea and tested positive for rotavirus by enzyme-linked immunosorbent assay methods. Serial follow-up biopsies, as well as clinical data, are documented and analyzed. These patients were followed up for an average of 168 days (range 33-534 days). Mean time of rotavirus diagnosis from transplant day was 794 days (range 38-2907 days). Self-limited diarrhea lasting 6-13 days (mean = 9 days) was the main presentation. Sixteen (69.6%) patients developed acute cellular rejection either concurrently with (i.e. six patients) or after (10 patients) RVE, often characterized by prominent mucosal plasmacytosis at an average of 22 days (range 0-94 days) from the day RVE was diagnosed. One-third of patients with acute rejection (i.e. five out of 16) required muromonab-CD3 rescue therapy. Two patients experienced graft loss (one from chronic rejection, another from sepsis). Rotavirus infection is a cause of diarrhea in adult small bowel transplant patients. The infection appeared to trigger cellular rejection that was associated with mucosal plasmacytosis, and sometimes required aggressive rescue therapy.
