[Association factors analysis of diarrhea in patients receiving kidney transplantation]

To investigate the factors in association with colorectal disorders in adult renal transplant recipients.

A retrospective cohort study was carried out with clinical, microbiological and management data regarding diarrhea in 513 renal transplant recipients from Jan. 2007 to Dec. 2012.

Of the 513 patients, 118(23.00%) with no history of ulcerative colitis, were found to have diarrhea after kidney transplantation. In the 118 patients, diarrhea was probably caused by administration of immunosuppressive agents in 65 cases (55.08%), in 30 cases (25.42%) diarrhea was antibiotics associated, and in 23 cases (19.49%) it was due to infections, including bacterial, fungal and viral infections. Diarrhea occurred soon after transplantation in most cases. Of the 118 patients, the symptom of diarrhea occurred in the first 1 month in 84 cases (71.19%), and in the next 5 months in 16 cases (13.56%), and the other 18 cases (15.05%) occurred after 180 days after transplantation. Of the 118 patients, 84 cases (71.19%) were relieved or cured after proper diets, the symptomatic therapy or the adjust meat of the doses of immunosuppressive agents: 18 cases (15.25%) needed to use or adjust the antibiotics , 16 cases (13.56%) had to stop mycophenolate mofetil and convert to other drugs.

Immunosuppressive agents, antibiotics and infection are the common causes of diarrhea after kidney transplantation. The outcome is good with appropriate conservative management.
