Patients and methods: Descriptive and analytical studies based on the retrospective collection of data on 125 patients’ records in the hepatogastroenterology unit of the University Hospital Campus of Lome (Togo) from January 1, 2008 to March 31, 2018 were included. Cirrhotic patients aged 15 years and older had performed cytochemical analysis of ascites fluid and upper gastrointestinal fibroscopy and had a protidogram. Statistical analysis was done by R Studio Software 3.4.2. Results: The mean age was 48.70 years;there was a male predominance (70.40%) with a sex ratio of 2.38. Protein levels in ascitic fluid was Conclusion: Our study noted that at an upper threshold of 1.10 g/dl, the SAAG significantly predicted the presence of EV.展开更多
目的:探讨血清-腹水白蛋白梯度(serum-ascites albumin gradient,SAAG)和腹水腺苷脱氨酶(adenosine deaminase,ADA)对结核性腹膜炎的诊断价值。方法:选取458例腹水患者进行回顾性分析,并将其分为4组:单纯渗出性结核性腹膜炎组(Ⅰa组)39...目的:探讨血清-腹水白蛋白梯度(serum-ascites albumin gradient,SAAG)和腹水腺苷脱氨酶(adenosine deaminase,ADA)对结核性腹膜炎的诊断价值。方法:选取458例腹水患者进行回顾性分析,并将其分为4组:单纯渗出性结核性腹膜炎组(Ⅰa组)39例,肝硬化合并结核性腹膜炎组(Ⅰb组)14例,肝硬化组(Ⅱa组)315例和其他原因组(Ⅱb组)90例。以所有患者血清白蛋白及腹水中的总蛋白浓度进行检测,计算出SAAG;并测定腹水中的ADA浓度。结果:Ⅰa组、Ⅰb组、Ⅱa组、Ⅱb组患者SAAG分别为6.97±1.81、8.24±2.15、20.32±5.24和17.40±4.83g/L;腹水ADA分别为55.06±12.34、49.21±9.96、10.24±3.65和16.88±5.72U/L。结果显示,SAAG和腹水ADA在Ⅰa组与Ⅱa组间,以及Ⅰb与Ⅱa组间比较差异均有显著性意义(P<0.01);而Ⅰa组与Ⅰb组间比较差异无显著性意义(P>0.05)。以SAAG<11g/L为临界值诊断结核性腹膜炎的敏感性为90.6%,特异性为95.6%,准确率为92.4%。以ADA>40U/L为临界值诊断结核性腹膜炎的敏感性为94.3%,特异性为95.6%,准确率为95.4%。结论:SAAG<11g/L,或腹水ADA>40U/L,尤其是后者,可作为诊断结核性腹膜炎的敏感指标。展开更多
