Peritoneal dialysis patients may need solute permeability transport evaluation during acute peritonitis. The aim of this study was to assess if the simplified mass transfer coefficient (MTCS) or the peritoneal equilibration test (PET) was equivalent to the complex MTC (MTCX) in solute transport evaluation during acute peritonitis in continuous ambulatory peritoneal dialysis (CAPD) patients. We studied 15 episodes of peritonitis (PTIS). Results were compared to a baseline patient study (PRE) and a control study done 30 days after diagnosis of peritonitis (POST). All peritoneal evaluation methods showed a significant increase in solute transport during acute peritonitis compared to baseline and control studies. There was an acceptable correlation between MTCX and simplified methods including the PET in the baseline and control studies. However, correlation between MTCX and simplified methods decreased during acute peritonitis. Likewise, the PET showed a better correlation with MTCX than MTCS. We conclude that the PET has an acceptable agreement with MTCX even during acute peritonitis, so the PET can be a useful tool in evaluating peritonitis-induced peritoneal permeability changes.
腹膜透析患者在急性腹膜炎期间可能需要进行溶质通透性转运评估。本研究的目的是评估在持续非卧床腹膜透析（CAPD）患者急性腹膜炎期间，简化质量传递系数（MTCS）或腹膜平衡试验（PET）在溶质转运评估方面是否等同于复杂的质量传递系数（MTCX）。我们研究了15例腹膜炎发作（PTIS）。将结果与患者基线研究（PRE）以及腹膜炎诊断后30天进行的对照研究（POST）进行比较。与基线和对照研究相比，所有腹膜评估方法均显示急性腹膜炎期间溶质转运显著增加。在基线和对照研究中，MTCX与包括PET在内的简化方法之间存在可接受的相关性。然而，在急性腹膜炎期间，MTCX与简化方法之间的相关性降低。同样，PET与MTCX的相关性优于MTCS。我们得出结论，即使在急性腹膜炎期间，PET与MTCX之间也具有可接受的一致性，因此PET可作为评估腹膜炎引起的腹膜通透性变化的有用工具。
