title: [Cytomegalovirus infection, a risk factor for acute graft rejection in renal transplant recipients. A case-controlled study].
abstract: OBJECTIVE
  We studied the relationship between cytomegalovirus infection and episodes of acute rejection after infection in renal graft recipients at the Reims University Hospital from 1989 to 1995.
  
  
  METHODS
  Two exposed versus nonexposed analyses were conducted, one (series 1) for CMV infection and the other (series 2) for CMV disease. For each analysis, exposed recipients were matched with nonexposed recipients for date of graft (+/- 6 months). Risk of acute rejection was assessed with univariate analysis then with multivariate analysis using logistic regression.
  
  
  RESULTS
  Among the 192 graft recipients included, 64 developed CMV infection, 77 had an infection (series 1) and 51 had CMV disease (series 2). In series 1, only failure of renal graft was a significant risk factor of acute rejection (OR = 10.4; 95% Cl 1.9-56.3). CMV infection was not a significant risk factor (OR = 1.06; 95% Cl 0.2-5.6). Conversely, in series 2, there was a 6-fold increase in the risk of acute rejection in recipients who developed CMV disease (OR = 5.98; 95% Cl 1.21-29.4).
  
  
  CONCLUSIONS
  The fact that CMV disease and not CMV infection is a risk factor of acute rejection in renal transplant recipients is an argument for implicating a general inflammatory reaction characteristic of CMV disease in the pathogenesis of acute rejection. This finding favors preventive treatment of CMV infection.
