ABSTRACT
BACKGROUND: The COVID-19 pandemic has led to emergency approval of treatment modalities unusual for viruses, such as therapeutic cytokine Hemadsorption(HA). This study aims to investigate the experience of salvage HA therapy and the effect of HA on routine laboratory tests. METHODS: Life-threatening COVID-19 patients followed up between April 2020 and October 2022 who underwent HA salvage therapy were retrospectively enrolled. Data derived from the medical records were evaluated to meet the assumptions of statistical tests, and those that met the relevant statistical rules were selected for further analysis. Tests of Wilcoxon, Paired-T, and repeated measures-ANOVA were used to analyse the laboratory tests performed before and after HA among the surviving and nonsurviving patients. P < 0.05 was selected for the statistical significance of the alpha. RESULTS: A total of 55 patients were enrolled in the study. Fibrinogen (p = 0.007), lactate dehydrogenase (LDH) (p = 0.021), C-reactive protein (CRP) (p < 0.0001), and platelet (PLT) (p = 0.046) levels showed a significant decrease with the HA effect. WBC (p = 0.209), lymphocyte (p = 0.135), procalcitonin (PCT) (p = 0.424), ferritin (p = 0.298), and D-dimer (p = 0.391) levels were not affected by HA. Ferritin level was significantly affected by survival status (p = 0.010). All patients tolerated HA well, and 16.4 % (n = 9) of the patients with life-threatening COVID-19 survived. CONCLUSION: HA is well tolerated even when used as a last option. However, HA may not affect WBC, lymphocyte, and D-dimer levels. In contrast, the effect of HA could limit the benefits of LDH, CRP, and fibrinogen in various clinical assessments. This study suggests that HA treatment could be beneficial even if selected as a salvage therapy.

The outbreak of corona virus disease 2019 (COVID-19) has spread to more than 70 countries worldwide and there was a higher mortality in those who developed serious illness.Cytokine storm syndrome is an important pathophysiological basis for COVID-19 patients developing into severe or critical conditions. It was indicated in the diagnosis and treatment scheme, by the National Health Commission of the People's Republic of China, that blood purifications such as plasma exchange, plasma adsorption, hemoperfusion, hemofiltration and plasmafiltration could be considered for use in the critical patients with cytokine storm syndrome. This expert consensus, proposed by the Chinese Society of Nephrology and the Nephrology Committee of Chinese Research Hospital Association, is to guide and standardize the clinical application of blood purifications in the treatment of severe or critical patients with COVID-19.

The real issue with the COVID-19 pandemic is that a rapidly increasing number of patients with life-threatening complications are admitted in hospitals and are not well-administered. Although a limited number of patients use the intensive care unit (ICU), they consume medical resources, safety equipment, and enormous equipment with little possibility of rapid recovery and ICU discharge. This work reviews effective methods of using filtration devices in treatment to reduce the level of various inflammatory mediators and discharge patients from the ICU faster. Extracorporeal technologies have been reviewed as a medical approach to absorb cytokines. Although these devices do not kill or remove the virus, they are a promising solution for treating patients and their faster removal from the ICU, thus relieving the bottleneck.
