Matching donor to recipient in liver transplantation: Relevance in clinical practice

Table 1 Risk stratification and need for cytomegalovirus prophylaxis

Donor CMV IgG status	Recipient CMV IgG status	Risk type1	Need for CMV prophylaxis
Positive	Positive	Low risk	Low
Positive	Negative	High risk	High
Negative	Positive	Low risk	Low
Negative	Negative	Low risk	Low

¹Patients needing induction with antithymocyte globulin and OKT3 or steroid boluses for acute rejection are considered high-risk irrespective of their CMV mismatch status. CMV: Cytomegalovirus.

Table 2 Risk of de novo hepatitis B in recipients receiving grafts from hepatitis B core antibody positive donors

Recipient status	Recipient HBVantibody status	Risk of de novo hepatitis
		No prophylaxis	With prophylaxis
HBV naive	HBcAb-, HBsAb-	58%	11%
No past infection, immunized	HBcAb-, HBsAb+	18%	2%
Past infection, immune	HBcAb+, HBsAb+	4%	3%
Past infection, not immune	HBcAb-, HBsAb+	14%	3%

Incidence in patients with or without prophylaxis is shown (Modified from Skagen et al[40]). HBV: Hepatitis B virus.
