In kidney transplant patients, chronic hepatitis B progresses more aggressively than in dialysis patients; this is due to the immunosuppression and the reduced activity of cytotoxic T lymphocyte, which increase viral replication.<a class="elsevierStyleCrossRef" href="#bib0130"><span class="elsevierStyleSup">3</span></a> Dialysis patients rarely present symptoms of acute hepatitis B and their transaminase levels are usually normal or mildly elevated during chronic infection.<a class="elsevierStyleCrossRefs" href="#bib0135"><span class="elsevierStyleSup">4,5</span></a> These differences may be explained by uraemia, vitamin B deficiency and the patient's nutritional status.

However, this is only achieved in a minority of immunocompetent patients and is rarely seen in immunocompromised patients. A more realistic objective is to suppress HBV replication efficiently and persistently to reduce hepatic necroinflammatory activity and halt or delay fibrosis progression to prevent the development of complications such as cirrhosis, decompensation of liver function and hepatocellular carcinoma.</p><p id="par0025" class="elsevierStylePara elsevierViewall">HBV infection treatment indications are based on viral load, transaminase levels and severity of liver failure. The dosage of all drugs given to patients with chronic kidney disease (CKD) must be adjusted and has to be administered with caution, serum creatinine and, in some cases, serum phosphorus levels should be monitorized. The use of interferon is contraindicated in kidney transplant patients due to risk of rejection.</p><p id="par0030" class="elsevierStylePara elsevierViewall">Universal vaccination of CKD patients, patients on dialysis and healthcare professionals are recommended.

This study, sponsored by the Spanish Liver and Kidney Association (AEHR) and the Dialysis Virus Group of the Spanish Society of Nephrology (SEN), is the first of its kind to incorporate the following objectives: (1) to determine the prevalence of chronic HBV infection in CRD patients undergoing renal replacement therapy with haemodialysis in Spain, and to evaluate liver disease-related aspects and their status in regard with kidney transplant; (2) to gain information about the immunisation against HBV in this population and the associated response factors.</p></span><span id="sec0010" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0070">Method</span><p id="par0045" class="elsevierStylePara elsevierViewall">A formulary comprising the study variables to be completed for every haemodialysis patient using their medical records.
