Abstract

Background. Elimination of intoxication syndrome is one of the main components of sepsis treatment. The Rheo-STAT study is an interventional open multicenter randomized controlled trial of the efficacy of Reosorbilact (“Yuria-Pharm”) in the treatment of intoxication syndrome. The study was conducted in 7 countries, patients of the sepsis subgroup were recruited in 5 of them (Ukraine, Moldova, Georgia, Kazakhstan, Uzbekistan). Objective. To determine the efficacy and safety of Reosorbilact in patients with sepsis. Materials and methods. The study involved 628 adult patients with sepsis, peritonitis, pneumonia and burns. The subgroup of sepsis consisted of 180 people (72 % males, mean age – 41.3 years), the most common comorbidities were cardiovascular diseases (24 %), diabetes mellitus (15 %), and infectious diseases (8 %). The inclusion criteria were the following: age 18-60 years, diagnosis of sepsis, established by the ACCP/SCCM criteria ≤24 hours before the initial visit, obtaining of the informed consent, baseline SOFA scale value ≥2. The primary endpoint was the total score on the SOFA scale on the 3rd day of treatment compared to the baseline value. The secondary endpoints included the change in the overall score according to the APACHE II, SAPS II, MODS, PSI/PORT, CURB-65 scales; changes in biochemical, immunological and integral markers of endogenous intoxication. Results and discussion. Low-volume infusion therapy with Reosorbilact (200-400 ml per day) resulted in an increase in circulating blood volume and a decrease in the total volume of infusions required without the risk of volume overload, which is especially important for critically ill patients. Exogenous lactate in Reosorbilact did not increase the content of endogenous lactate (1st day – 2.27 mmol/L, 3rd day – 1.63 mmol/L), which indicates the high safety of the solution. In the complex of intensive care administration of Reosorbilact helped to reduce hyperthermia (1st day – 38.2 °C, 3rd day – 36.8 °C, p<0.001), heart rate (1st day – 95.43 beats/min, 3rd day – 81.13 beats/min, p<0.001) and the number of leukocytes (1st day – 14.5×109/L, 3rd day – 8.8×109/L) as a marker of endogenous intoxication. During 3 days of therapy Reosorbilact also normalized the acid-base composition of the blood. Conclusions. 1. Elimination of intoxication syndrome is one of the main components of sepsis treatment. 2. Reosorbilact infusion therapy increases the volume of circulating blood without the risk of volume overload. 3. The inclusion of Reosorbilact in the complex treatment of sepsis after 3 days provides a decrease in body temperature, heart rate, white blood cell count and normalization of the acid-base composition of the blood.
Reosorbilact对脓毒症患者的疗效和安全性的开放多中心随机对照试验的经验
背景。消除中毒综合征是脓毒症治疗的主要组成部分之一。Rheo-STAT研究是一项介入性开放多中心随机对照试验,研究Reosorbilact(“Yuria-Pharm”)治疗中毒综合征的疗效。该研究在7个国家进行,其中5个国家(乌克兰、摩尔多瓦、格鲁吉亚、哈萨克斯坦、乌兹别克斯坦)招募了脓毒症亚组患者。目标。目的:探讨Reosorbilact治疗脓毒症的疗效和安全性。材料和方法。这项研究涉及628名患有败血症、腹膜炎、肺炎和烧伤的成年患者。脓毒症亚组包括180人(72%男性,平均年龄- 41.3岁),最常见的合并症是心血管疾病(24%),糖尿病(15%)和传染病(8%)。纳入标准为:年龄18-60岁,诊断为脓毒症,就诊前≤24小时根据ACCP/SCCM标准确定,获得知情同意,基线SOFA量表值≥2。主要终点是治疗第3天SOFA量表的总得分与基线值的比较。次要终点包括APACHE II、SAPS II、MODS、PSI/PORT、CURB-65量表的总分变化;内源性中毒的生化、免疫学和整体标志物的变化。结果和讨论。Reosorbilact小容量输注治疗(每天200- 400ml)可增加循环血容量,减少所需输注总量,且无容量过载风险,这对危重患者尤为重要。外源乳酸加入Reosorbilact后,内源乳酸含量未增加(第1天- 2.27 mmol/L,第3天- 1.63 mmol/L),说明该溶液安全性高。在重症监护复诊中,给予Reosorbilact有助于降低高热(第1天- 38.2°C,第3天- 36.8°C, p<0.001),心率(第1天- 95.43次/分钟,第3天- 81.13次/分钟,p<0.001)和白细胞数量(第1天- 14.5×109/L,第3天- 8.8×109/L),这是内源性中毒的标志。在3天的治疗期间,Reosorbilact也使血液的酸碱组成正常化。结论:1。消除中毒综合征是脓毒症治疗的主要组成部分之一。2. Reosorbilact输注疗法增加了循环血容量而没有容量过载的风险。3.在脓毒症3天后的复杂治疗中加入Reosorbilact可以降低体温、心率、白细胞计数和血液酸碱组成的正常化。
