The relationship between hepatocellular carcinoma recurrence and hepatitis B virus recurrence after liver transplantation / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To investigate the relationship between hepatocellular carcinoma (HCC) recurrence and hepatitis B virus (HBV) recurrence.</p><p><b>METHODS</b>The clinical data of 340 patients underwent liver transplantation due to HBV related end-stage liver disease and received long-term follow up in our hospital from Jan 2004 to Dec 2008 were retrospectively analyzed. All patients received nucleoside analogues therapy formally before entering into the waiting list and nucleoside analogues combined low-dose HBIG therapy during and after transplantation. Patients were regularly followed up at the outpatient, monitoring the HBV recurrence and survival. Multivariate Cox regression analysis was used to evaluate the risk factors for hepatitis recurrence.</p><p><b>RESULTS</b>33 patients suffered from HBV recurrence post transplantation. The 1-, 3- and 5- year recurrence rates were 7.0%, 10% and 13% respectively. The median HBV recurrence time was 5 months (1-21 months). COX regression analysis revealed that risk factors for HBV recurrence were HCC (HR = 2.98; 95% CI 1.08-8.25; P < 0.05) and pre-transplantation HBV-DNA load over 5 log10 copies/ml (HR = 3.99; 95% CI 1.85-8.62; P < 0.01). Further stratified analysis showed that patients who suffered from carcinoma recurrence had a higher incidence of HBV recurrence than those who did not, which were 27.9% and 8.7% (HR = 4.58;95% CI 1.88-11.12; P < 0.01) respectively. 12 patients suffered from both HCC and HBV recurrence. Spearman correlation analysis demonstrated a strong correlation between HBV and HCC recurrence times (r = 0.583, P < 0.05).</p><p><b>CONCLUSIONS</b>Post transplantation HCC recurrence is a risk factor for HBV recurrence.</p>

Application of somatostatin combined with oral vancomycin in the treatment of intestinal obstruction after liver transplantation / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the effect of somatostatin combined with oral vancomycin in the treatment of intestinal obstruction after liver transplantation.</p><p><b>METHODS</b>Fifty-eight cases of intestinal obstruction after liver transplantation from Jan. 2005 to Dec. 2006 were divided into two groups: Group A (from Jan. 2005 to Dec. 2005) received traditional treatment, including fasting,gastrointestinal decompression, maintaining electrolyte and acid-base balance, enteral and parenteral nutrition support and antibiotics; Group B (from Jan. 2006 to Dec. 2006) received somatostatin combined oral vancomycin in addition to the above mentioned traditional treatment.</p><p><b>RESULTS</b>Fifty-eight cases out of 441 patients (13%) suffered from intestinal obstruction after liver transplantation. Group B had a better outcome as compared with Group A, including a quick recovery of flatus and stool, [(7.1+/-2.0) d and (8.4+/-2.4) d vs (9.1+/-3.0) d and (10.8+/-3.4) d] (P<0.05), less amount of gastric drainage [(298+/-58) ml/d vs (485+/-106) ml/d](P<0.05). The rate of intestinal flora imbalance in Group B was 55%, which was significantly less than the 77% in Group A(P<0.05).</p><p><b>CONCLUSION</b>The application of somatostatin combined with oral vancomycin can improve the symptoms of intestinal obstruction after liver transplantation and decrease the rate of intestinal flora imbalance.</p>

The distribution and pathogen of bacteria infection in patients after liver transplantation / 中华外科杂志

<p><b>OBJECTIVE</b>To find out the epidemiology of bacteria infection after orthotopic liver transplantation (OLT).</p><p><b>METHOD</b>Postoperative bacteria infection of 451 OLT cases were retrospectively analyzed.</p><p><b>RESULT</b>Bacteria infection were detected in 239 OLT cases, and the infection rate was 52.9%. Sum up to 304 bacilli lines were separated from all above cases. Among them, the detectable Gram-positive bacilli (G(+)) accounted for 59.9% (182/304), while Gram-negative bacilli (G(-)) accounted for 40.2% (122/304). The impressionable organ were respiratory tract and bile duct, which occupying 81.5% (248/304) and 15.1% (46/304) among all infective cases respectively. The main infected strain were G(+) bacteria in respiratory tract, account for 65.3%; while G(-) bacteria were mainly in bile duct, account for 60.9%. There was significant difference between each other (P = 0.018).</p><p><b>CONCLUSIONS</b>The bacteria infection rate was high after OLT, and the main infected strain was the G(+) bacteria. Most fo them were the opportunistic pathogenic bacteria and the antibiotic multi-resistant bacteria. The bacteria category was significantly related to the infected tissue, according to which we could adopt corresponding antibacterial approach.</p>
