PurposeThis study aimed to evaluate the clinical effects of hemoperfusion plus continuous veno-venous hemofiltration in the treatment of patients with multiple organ failure after wasp stings and investigate its impacts on cytokines.MethodsA total of 12 patients with multiple organ failure after wasp stings admitted to Xijing Hospital were included in the present study between January 2017 and January 2019. All patients received hemoperfusion plus continuous veno-venous hemofiltration treatment in addition to conventional treatment after admission. Procedure of treatment was conducted as the following: hemoperfusion (2 h/day) and followed by continuous veno-venous hemofiltration (22 h/day) for at least 5 days. Patients' clinical features, serum laboratory tests, and hemodynamic variables were monitored. The blood samples were taken to measure the changes of plasma cytokines.ResultsAll 12 patients survived in the observation period. After hemoperfusion plus continuous veno-venous hemofiltration treatment, there were significant improvements in indicators of liver function, renal function, state of consciousness, and mediators in blood circulation, including alanine transaminase, aspartate transaminase, creatine kinase, blood urea nitrogen, serum creatinine, myoglobin, C-reactive protein, and so on. In these patients, acid-base metabolism returned to normal levels; Acute Physiology and Chronic Health Evaluation II score, Simplified Acute Physiology Score II score, and Sequential Organ Failure Assessment score lowered markedly. Furthermore, the plasma levels of interleukin 1β, interleukin 4, interleukin 6, interleukin 8, and interleukin 10 in these patients were significantly decreased; no significant change was shown in the level of tumor necrosis factor α.ConclusionOur results revealed that hemoperfusion plus continuous veno-venous hemofiltration was effective in the management of patients with multiple organ failure after wasp sting via the non-specific removal of the wasp venom and inflammatory cytokines.
