Which class in the Child-Turcotte-Pugh system is associated with the best prognosis?

  1. Class A

  2. Class B

  3. Class C

  4. Class D

The correct answer is: Class A

In the Child-Turcotte-Pugh system, Class A indicates mild liver disease with the best prognosis compared to the other classes. This classification system is used to assess the severity of liver disease and helps to predict the outcome of patients with chronic liver conditions. Class A signifies that the patient has well-preserved liver function and exhibits minimal impairment of synthetic capabilities, which is reflected in laboratory parameters such as bilirubin levels, albumin, and prothrombin time. Patients in Class A typically have fewer complications and a higher likelihood of surviving longer without the need for interventions like liver transplantation. The good prognosis associated with Class A is primarily due to their better liver function status and the less severe clinical signs of liver disease. In contrast, Class B suggests moderate liver dysfunction, and Class C indicates severe liver dysfunction, both of which correlate with poorer prognoses. Class D is not a recognized category in this classification, adding to the clarity that Class A is the best prognosis group within the established classification.
