RESUMEN
BACKGROUND@#As a large, prospective, multicenter study-based prognostic score for hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF), the Chinese group on the study of severe hepatitis B-acute-on-chronic liver failure score (COSSH-ACLFs), has been approved by some foreign scholars; however, its predictive value needs to be verified. This study investigated the predictive value of COSSH-ACLFs for short-term prognosis in Chinese patients with HBV-ACLF.@*METHODS@#This retrospective cohort study included 751 patients with HBV-ACLF admitted to the Fifth Medical Center of Chinese PLA General Hospital between January 2011 and December 2014. Spearman method was used to assess the correlation of COSSH-ACLFs with classical scores. Different COX multivariate regression models were used to confirm the relationship between COSSH-ACLFs and short-term prognosis in patients with HBV-ACLF, and stratified analysis was used to further verify the stability of this relationship. We compared the predictive powers of COSSH-ACLFs and other classical scores using area under the receiver operating characteristic curve (AUROC) and Z-test.@*RESULTS@#A total of 975 patients with HBV-ACLF were screened, and 751 were analyzed (623 male and 128 female). COSSH-ACLFs was the highest in patients with end-stage ACLF, followed by those with middle- and early-stage ACLF (H = 211.8, P < 0.001). In the fully adjusted model, COX multivariate regression analysis revealed that COSSH-ACLFs (as a continuous variable) was independently and positively correlated with mortality risk in patients with HBV-ACLF at 28 days (hazard ratio [HR]: 1.37 [1.22, 1.53], P < 0.001) and 90 days (HR: 1.43 [1.29, 1.58], P < 0.001). The same trend could be observed in the crude model and minimally adjusted model. The AUROCs of COSSH-ACLFs for 28-day and 90-day prognoses in patients with HBV-ACLF were 0.807 and 0.792, respectively, indicating a stronger predictive accuracy than those of classic models.@*CONCLUSIONS@#COSSH-ACLFs, with a superior predictive accuracy compared with other classical scores, can strongly predict short-term prognosis in Chinese patients with HBV-ACLF.

RESUMEN
<p><b>OBJECTIVE</b>To describe the outcomes and recurrence of autoimmune hepatitis (AIH) after liver transplantation.</p><p><b>METHODS</b>Clinical data of 16 patients with AIH who underwent liver transplantation were analyzed retrospectively. The postoperative cumulative survival rate of the patients was calculated. The postoperative rejections and AIH recurrence were analyzed. The Kaplan-Meier method was used for statistical analysis of survival.</p><p><b>RESULTS</b>All patients were female, with an average age of 52.6 years (range: 41-66 years), and an average MELD score of 21.4. According serological analysis, 15 patients were AIH type 1 and 1 patient was AIH type 2. Three patients died, including 2 of pulmonary infection and 1 of graft dysfunction.The 1-, 2-and 5-year cumulative survival rates were 93.8%, 87.1% and 79.1%, respectively. Five cases (31.3%) of recurrent AIH were diagnosed based on histological evidence. Acute rejection occurred in 6 (37.5%) patients, and de novo HBV infection occurred in 1 (6.3%) patient.</p><p><b>CONCLUSION</b>Liver transplantation is an effective treatment for end-stage AIH. Recurrence and rejection were commonly associated with AIH, but did not negatively impact patient survival.</p>

<p><b>OBJECTIVE</b>To explore the distribution and clinical significance of HBV genotypes in patients with HBV infection in China.</p><p><b>METHOD</b>Serum samples were collected from 2922 patients with HBV infection. HBV genotyping was performed with type-specific primers polymerase chain reaction, and the virological and biochemical markers were detected, which differences in the genotypes distribution between various regions and liver function and virological markers between various HBV genotyping were analyzed.</p><p><b>RESULT</b>The genotype B, C, B + C, D of 2922 patients with HBV infection accounted for 15.9%, 83.5%, 0.41%, 0.21% respectively. In Northern China, genotype C was most prevalent, accounting for 90% of all cases, while it was less common in Southern China; genotype C was present in Zhejiang and Jiangsu provinces, but genotype B was comparatively more common in Guangdong, Hunan, Hubei, and Jiangxi provinces. B, C genotype HBV infection patients in the sex difference was not statistically significant; B genotypes compared with C genotype HBV infection patients, the average age of is less (P < 0.001); HBeAg positive rate of C genotype HBV infection patients are higher than that of B genotype (P = 0.023); Viral load of genotype C HBV infection patients is higher than that of genotype B (P = 0.038); Cholinesterase and Albumin levels of genotype C HBV infection patients are lower than that of genotype B (P values were 0.016, <0.001).</p><p><b>CONCLUSION</b>There were HBV genotype B, C, B + C and D in Chinese patients with HBV infection, with genotype B and C being the major ones. Mainly in northern regions of genotype C, C genotype significantly reduced the southern region, some of the southern region dominated by B genotype. Genotype C HBV infection patients are older, and their HBeAg-positive rate is higher, and their liver damage is more severe, but their viral load is less.</p>

<p><b>OBJECTIVE</b>To analysis the relationship between HBV BCP A1762T/G1764A double mutation with acute on chronic liver failure (ACLF).</p><p><b>METHODS</b>HBV BCP A1762T/G1764A double mutation was detected in 166 HBV chronic infection patients by nested PCR and direct DNA sequencing. The mutation rate was compared among the patients with different disease course.</p><p><b>RESULTS</b>Among 166 patients, 45 patients, 45 patients, 49 patients and 27 patients were diagnosed as chronic hepatitis B (CHB), liver cirrhosis (LC), ACLF and hepatocellular carcinoma (HCC), respectively. A1762T/G1764A double mutation rate was 40.0% (18/45), 84.4% (38/45), 73.5% (36/49) and 92.6% (25/27) respectively in different groups. However, A1762T/G1764A double mutation rate has no difference between ACLF based on CHB and LC (P = 0.502) and between patients with HBeAg positive and negative (P = 0.735). HBV DNA level (log) of patients with A1762T/G1764A double mutation was 5.68 +/- 1.36, lower than but having no significant statistic difference compared to patients without the double mutation (6.14 +/- 1.81, P = 0.075).</p><p><b>CONCLUSION</b>A1762T/G1764A double mutation has a close relationship with the progress of HBV-infection diseases, but is not specific to patients with ACLF. And patients with BCP double mutation have similar HBV DNA levels and HBeAg status with patients without the double mutation.</p>

<p><b>OBJECTIVES</b>To study the clinical characteristics of hepatic failure with aspergillosis.</p><p><b>METHODS</b>The data of hepatic failure patients with fungal infection hospitalized in our hospital form January 1985 to June 2006 were collected. This research mainly focused on the clinical characteristics of the patients co-infected with aspergillosis.</p><p><b>RESULTS</b>The occurrence of aspergillosis was 20.5% (104 cases) among 507 hepatic failure patients with fungal infection. Compared with other fungal infection in hepatic failure patients, the effective rate of antifungal therapy and the improvement rate of underlying disease were worse in patients with aspergillus infection (36.5% vs 57.8%, P = 0.000; 26.0% vs 36.7%, P = 0.049). Aspergillus fumigatus was the most common species among 108 fungal species. The species next to Aspergillus fumigatus were Aspergillus niger and Aspergillus flavus. The mainly infected organ was lung and its clinical manifestation was atypical. Liver function could be improved with effective anti-fungus therapy.</p><p><b>CONCLUSIONS</b>Diagnosis and treatment of aspergillosis is difficult in hepatic failure patients co-infected with aspergillosis. Early and effective antifungal therapy is helpful to the recovery of liver function in the hepatic failure patients suspected with aspergillosis co-infection.</p>
