Abbreviated medical protocols from EdREN, the website of the Renal Unit of the Royal Infirmary of Edinburgh

Important: Protocol superseded July 2009 - see new version here at www.edren.co.uk.
That website is in development - you can ignore the 'This website is not ready' signs ONLY for the Transplant protocols. Others are not updated or fully transferred.

Valganciclovir is prescribed for prevention of CMV disease in high risk transplant patients identified as follows:

Prescription is initiated in hospital within 10 days of transplantation.  Therapy will be continued in primary care for up to a total of 90 days treatment for which a shared-care protocol will be provided.

Valganciclovir is available as 450mg tablets (pink) and the brand name is Valcyte®.  The tablets should be taken with food and not broken or crushed.

The initial valganciclovir dose is dependent on renal function as shown in the table below:

Creatinine clearance (ml/min)

Prophylactic dose

>60

900mg od

40 to 59

450mg od

25 to 39

450mg every 2 days

10 to 24

450mg twice weekly

FBC and LFTs must be monitored daily during therapy.

 

Testing for CMV infection

Surveillance is not routine since introduction of valganciclovir. Investigate any episode of illness which might be CMV related, at any stage following a transplant operation.

Check CMV serology together with samples of EDTA bloodfor buffy coat culture and serum sample for PCR. These should be requested following discussion with the Virologist.

An EDTA (9 ml or 3 x 2.5 mls sample for CMV should be sent to Virology whenever is clinically relevant. ON request form include details of illness (e.g. pyrexia or hepatitis etc.) Request CMV PCR and CMV culture. Please try to ensure samples reach Virus Lab by midday, and within 2h. The rapid culture may provide an answer sooner than PCR in some cases.

It will often be appropriate to send respiratory or other samples to virology - bronchoalveolar lavage or induced sputum for investigation as usual or colon biopsies.
