Sinusoid endotheliitis as a histological parameter for diagnosing acute liver allograft rejection

Abstract

AIMTo investigated the feasibility of using sinusoidal endotheliitis (SE) as a histological marker for liver allograft rejection.METHODSWe compared the histological features of 88 liver allograft biopsies with acute cellular rejection (ACR) and 59 cases with no evidence of ACR. SE was scored as: (1) focal linear lifting up of the endothelial cells by lymphocytes with no obvious damage to adjacent hepatocytes; (2) focal disruption of the endothelial lining by a cluster of subendothelial lymphocytes (a group of > 3 lymphocytes); and (3) severe confluent endotheliitis with hemorrhage and adjacent hepatocyte loss.RESULTSThe sensitivity and specificity of SE was 81% and 85%, respectively. Using SE as the only parameter, the positive predictive value for ACR (PPV) was 0.89, whereas the negative predictive value for ACR (NPV) was 0.75. The correlation between RAI and SE was moderate (R = 0.44, P < 0.001) (Figure 3A), whereas it became strong (R = 0.65, P < 0.001) when correlating SE with the venous endotheliitis activity index only.CONCLUSIONOur data suggest that SE scoring could be a reliable and reproducible supplemental parameter to the existing Banff schema for diagnosing acute liver allograft rejection.

An immunogenomic signature for molecular classification in hepatocellular carcinoma

“… 20 Immune system disorders are associated with lymphocyte infiltration of the liver. 21 , 22 Therefore, the liver is essential to the regulation of immune defense. 23 Thus, immune pathways in the liver may provide more refined prognostic prediction for liver diseases.…”
