Objective To investigate the clinical features of acute hepatitis B( AHB) and acute exacerbation of chronic hepatitis B( CHB)for differential diagnosis. Methods A retrospective analysis was performed on the clinical data of 96 AHB patients and 124 patients with acute exacerbation of CHB,who were admitted to the Public Health Clinical Center Affiliated to Fudan University from June to December,2014. Comparison of continuous data between the two groups was made by Mann Whitney U test,while comparison of categorical data was made by chi- square test. Results There were no significant differences in the age of onset and sex between the AHB group and the acute exacerbation of CHB group; the incidence was higher in males than in females. Sexual transmission and iatrogenic transmission were the main routes of transmission for AHB,while mother- to- child transmission was the main route of transmission for acute exacerbation of CHB. The sensitivity and specificity of alanine aminotransferase( ALT) level ≥1072 U / L for diagnosing AHB were 78. 6% and 79. 2%,respectively. The sensitivity and specificity of S / CO ≥13. 6 in the anti- HBc- Ig M test for diagnosing AHB were 94. 5% and 89. 3%,respectively. At week 2 after admission,the AHB group showed significantly greater decreases in levels of HBs Ag,HBe Ag,and hepatitis B virus( HBV) DNA than the acute exacerbation of CHB group( P < 0. 05). At week 8 after admission,the AHB group had significantly higher HBs Ag clearance rate,anti- HBs seroconversion rate,HBe Ag clearance rate,anti- HBe seroconversion rate,and HBV DNA clearance rate than the acute exacerbation of CHB group( P < 0. 05). Conclusion It is helpful for making the differential diagnosis between AHB and acute exacerbation of CHB to know the route of transmission,ALT level,anti- HBc- Ig M test result( S / CO value),HBV DNA clearance rate,and the seroconversion rates of HBV markers.
而BE在理论上可能降低PD术后DGE的发生,故近些年部分研究者[1-4, 7]将BE引入PD中。有研究[1-2, 7, 20]发现,BE方式可以降低PD术后DGE、碱性反流性胃炎或边缘性溃疡的发生。部分研究[7, 21]甚至报道其降低了胰瘘的发生率。在Hochwald等[7]的研究中,BE组在DGE总体发生率、尽早拔除胃管、尽早进食、尽早出院等方面与非BE组有统计学差异,而临床相关的DGE(B级+C级)差异更加明显(7% vs 31%,P<0.01)。Xu等[2]研究发现,BE组DGE发生率显著降低(6.7% vs 26.87%,P<0.001),且多因素分析显示BE是唯一的独立危险因素;同时BE组有着更低的临床胰瘘发生率(P<0.001)。Meng等[1]研究显示,胰腺残端连续缝合加BE能显著降低DGE(P<0.01)及临床相关PF发生率(P<0.05),但是该实验未能明确BE在结果中的具体作用,亦有可能是连续缝合降低了胰瘘的发生进而降低DGE的发生。部分循证学研究[22]同样支持BE可降低DGE发生率的观点。但是不同研究之间在重建消化道距离(BE口与胃肠吻合口)和BE吻合口径上不一致,并在术后治疗和护理方案上均存在差[1-4, 7],部分研究[3-4]结果并不支持BE可以降低DGE发生率的观点。
