title: [Antiviral prophylaxis and pre-emptive therapy for the prevention of Cytomegalovirus infection in renal transplant recipients: guideline from the Italian Society of Nephrology].
abstract: BACKGROUND
  The current 3rd edition of the Italian Society of Nephrology guidelines has been drawn up to summarize evidence of key intervention issues on the basis of systematic reviews (SR) of randomized trials (RCT) or RCT data only. In the present guideline, evidence of antiviral prophylaxis and pre-emptive treatment for preventing cytomegalovirus (CMV) infection in kidney transplant recipients is presented.
  
  
  METHODS
  SR of RCT and RCT on antiviral prophylaxis and pre-emptive treatment for CMV infection in kidney transplant recipients were identified referring to a Cochrane Library and Renal Health Library search (2005 update).
  
  
  RESULTS
  Evidence from 4 SR of RCT was gathered to address this issue. Methodological quality of available RCT included in these SR was suboptimal. Antiviral prophylaxis is associated with a significant reduction in the risk of CMV infection and all-cause mortality in CMV-negative and CMV-positive renal transplant recipients from CMV-positive donors, regard-less of the immunosuppressive treatments used (evidence from SR). Pre-emptive therapy has been found to be effective in preventing CMV disease but not all-cause mortality in these patients, even if evidence is less satisfactory compared to data on antiviral prophylaxis (evidence from SR). There is insufficient evidence of conclusive recommendations on treatment of CMV-negative recipients of renal transplants from CMV-negative donors.
  
  
  CONCLUSIONS
  In kidney transplant patients current available evidence supports the hypothesis that antiviral prophylaxis and pre-emptive therapy are effective in preventing CMV disease; but antiviral should be the treatment of choice. Further studies are necessary on the treatment of CMV-negative recipients from CMV-negative donors.
