    Abstract:
    The effectiveness of a tonsillectomy before kidney transplantation (KTx) in suppressing the recurrence of IgA nephropathy (IgAN) has never been studied. The aim of this study was to analyze the effectiveness of a preoperative tonsillectomy for preventing IgAN recurrence and to identify predictive risk factors for IgAN recurrence. Of the 462 recipients who underwent a KTx between 2006 and 2011, a total of 78 patients had biopsy-proven IgAN as their primary disease. Among these 78 patients, 28 patients (group 1) underwent a tonsillectomy and 50 patients (group 2) did not undergo a tonsillectomy before KTx. The time to recurrence was 15.5±8.7months, in group 1 and 20.2±18.6months in group 2. No significant difference was observed between the two groups (P=0.63). Using a multivariate Cox regression analysis, ABO incompatible KTx and acute rejection were associated with a lower incidence of recurrence (P=0.02 and 0.002 respectively). These results suggested that a preoperative tonsillectomy might not affect the recurrence of IgAN during a short-term follow-up period, whereas preoperative desensitization and the use of a higher steroid dose were effective for suppressing the recurrence of IgAN.
