- Risk stratification of microbial transmission from donor to recipient in liver transplantation (LT).
| Risk classification | Description |
|---|---|
| Unacceptable risk | Diseases with no definitive treatment, such as HIV, MDR bacterial infections, and some viral CNS infections. Encephalitis without proven cause falls in this category, as well as active tuberculosis |
| Increased but acceptable risk | Justified by the severity of the recipient condition and risk of death. Examples are HCV and HBV in the donor. |
| Calculated risk | When recipients have the same disease as the donor or in cases where the infection can be mitigated by antibiotics, such as septicemia and bacterial meningitis. |
| Non-assessable risk | When the risk cannot be estimated based on donor data, such as organs from donors with highly resistant bacteria or fungal infection. The use of these organs should be avoided. |
| Standard risk | Donors whose evaluation did not reveal transmissible disease. |
HIV: human immunodeficiency virus, MDR: multi drug-resistant, HCV: hepatitis C virus
