Scientific title	Determining a viral load threshold for pre-emptive therapy for cytomegalovirus infection in transplant patients using real time PCR monitoring
Study objectives	The aim of this study is to determine if quantitative measures of CMV viraemia can be applied to improve the treatment of CMV infection, and to evaluate the threshold of CMV viral load for initiation or discontinuation of pre-emptive therapy.
Ethics approval(s)	Research Ethics Committee (REC), 20/11/2002, ref: 6077, re-approved on the 16th November following an MHRA audit
Health condition(s) or problem(s) studied	Cytomegalovirus (CMV) infection
Intervention	Group A: 72 patients with low level CMV reactivation Group B: 106 patients receiving pre-emptive therapy
Intervention type	Other
Primary outcome measure	Current information as of 29/07/2009: 1. The number of patients in Group A with a low level of CMV reactivation who subsequently develop a viral load greater than 3000 copies/ml. 2, The number of patients in Group B who develop a second episode of a viral load above 3000 copies/ml after therapy has been discontinued at the defined viral load cut-offs. Initial information at time of registration: Number of patients receiving another course of therapy because viral load increases above 3000 copies/ml.
Secondary outcome measures	Current information as of 29/07/2009: 1. The duration of antiviral therapy needed to treat CMV viraemia 2. The rate of increase in viral load prior to starting pre-emptive therapy 3. Correlation of viral loads with CMV-specific immune function
Overall study start date	05/12/2002
Completion date	01/04/2011
