Aminopyrine breath test improves long-term prognostic evaluation in patients with alcoholic cirrhosis in Child classes A and B.

Abstract

In a 4-year survival study, we evaluated the prognostic value of the aminopyrine breath test and the Child-Turcotte-Pugh score in 190 alcoholic patients. Using aminopyrine breath test results, the patients were stratified into group 1 (aminopyrine breath test > 2%), group 2 (1% < or = aminopyrine breath test < 2%) and group 3 (aminopyrine breath test < 1%). Survival rates at 4 years were 68% in group 1, 35% in group 2 and 17% in group 3. Using the Child-Turcotte-Pugh score, survival rates at 4 years were 67% in Child-Turcotte-Pugh class A, 40% in class B and 7% in class C. To assess the value of aminopyrine breath test as an adjunct to Child-Turcotte-Pugh score in prognostic evaluation of patients with cirrhosis, two approaches have been used: a regression analysis using Cox's proportional hazard model by including the Child-Turcotte-Pugh score and aminopyrine breath test value, and the log-rank test to assess the prognostic value of aminopyrine breath test in each Child-Turcotte-Pugh class separately. The regression analysis showed that both parameters, the Child-Turcotte-Pugh score and the aminopyrine breath test results, were accepted in the model, suggesting that the aminopyrine breath test was still significantly related to survival once the Child-Turcotte-Pugh score had been entered into the model. Analysis of the prognostic value of the aminopyrine breath test in each Child-Turcotte-Pugh class separately indicated, however, that the contribution was negligible in the Child-Turcotte-Pugh class C.(ABSTRACT TRUNCATED AT 250 WORDS)
