Evaluation of the use of combined extracorporeal detoxification in patients with severe acute pancreatitis: a retrospective cohort study

INTRODUCTION: Morbidity and mortality of severe acute pancreatitis (SAP) remains high. The most important direction of therapy is the relief of endotoxicosis. The use of extracorporeal detoxification (ECD) is a debatable problem. OBJECTIVE: Improving the results of treatment of patients with SAP, through the use of ECD methods. MATERIALS AND METHODS: The study included 25 patients. Group 1: ECD included 9 patients who used standard therapy with selective hemoperfusion (HP) and continuous veno-venous hemofiltration (CVVHF). Group 2 (control) 16 patients received standard therapy. We performed a comparative analysis of the main clinical and laboratory parameters and treatment outcomes between the groups. RESULTS: The use of ECD allowed to reduce the number of leukocytes from 14.9 to 8.6 × 109/l by 5 days of therapy in group 1, and from 17.6 to 16.1 × 109/l in group 2, respectively. The dynamics of CRP concentration from 1 to 5 days changed from 315.6 to 184.6 mg/ml and 274.2 to 352.9 mg/ml in groups 1 and 2, respectively. The level of PCT concentration on days 1–5 decreased from 4.5 to 2.1 ng/ml and 3.95 to 6.9 ng/ml in groups 1 and 2, respectively. The concentration of IL-6 decreased from 1624.3 to 914.3 pg/ml in group 1, and increased from 1529.8 to 1861.8 pg/ml in group 2, respectively. The dynamics of pH in group 1 was from 7.14 to 7.4 by the 5th day of therapy and 7.13 to 7.22 in group 2, respectively. SOFA by day 5 in group 1 was 4 points and 11 points in group 2, respectively. CONCLUSIONS: The use of HP and CVVHF in complex intensive care is accompanied by a significant regression of markers of endogenous intoxication, resolution of the acid-base state and reduces the severity of organ dysfunction and the risk of adverse outcomes, compared with standard treatment.
