Therapeutic Apheresis and Dialysis最新文献

Introduction: Coronavirus disease 2019 (COVID-19) is associated with a marked increase in the inflammatory cytokines, IL-6 and IL-18. Blood purification therapy aimed at controlling cytokines is one treatment option; however, evidence of its effectiveness is needed. Plasma exchange with dialysis (PED) is a blood purification method involving selective plasma exchange with dialysate flowing through the outer hollow fiber of the plasma separator. In this retrospective study, we investigated the efficacy of continuous PED (cPED) over 48 h in five patients with severe COVID-19.

Methods: We assessed changes in IL-6 and IL-18, as well as adiponectin (APN).

Results: There were no significant differences in changes in IL-6 and IL-18, but there was a marked improvement in cases with abnormally high IL-6 and IL-18 levels at baseline. APN, which inhibits inflammatory cytokines, was significantly elevated post-cPED.

Conclusion: Our results suggest that cPED therapy is an effective treatment for COVID-19.

Objective: To investigate the effect of sodium thiosulfate (STS) on serum calcification factors in patients undergoing maintenance hemodialysis.

Methods: Forty-four Patients were randomly divided into control group (n = 22) and observation group (n = 22) by envelope method (block 4 randomization). The control group received routine treatment while observation group was treated with STS on the basis of routine treatment. The biochemical indicators, including BUN, UA, SCr, Ca²⁺ , P^3- , calcium-phosphorus product, PTH, hs-CRP, TG, TC, HDL, LDL, and serum calcification factor MGP, FA, FGF-23, and OPG levels were compared before and after treatment.

Results: Control group had no statistically significant difference in the levels of vascular calcification factors MGP, FA, FGF-23, and OPG before and after treatment (p > 0.05). Whereas observation group had higher levels of MGP and FA, and lower levels of FGF-23 and OPG after treatment than before treatment (p < 0.05). The levels of MGP and FA in observation group were higher than those in control group, and FGF-23 and OPG were lower than those in control group (p < 0.05).

Conclusion: It is speculated that sodium thiosulfate can alleviate the progression of vascular calcification by changing the levels of calcification factors.

Introduction: Indoxyl sulfate (IS) is a protein-bound uremic toxin that causes uremic sarcopenia. IS has poor dialysis clearance; however, the addition of a binding competitor improves its removal efficiency.

Methods: Dialysis experiments were performed using N-acetyl-l-tryptophan (L-NAT) instead of l-tryptophan (Trp) using pooled sera obtained from dialysis patients. The molecular structures of L-NAT and Trp were similar to that of IS. Therefore, we examined whether Trp and L-NAT were involved in muscle atrophy in the same manner as IS by performing culture experiments using a human myotube cell line.

Results: The removal efficiency of L-NAT was the same as that of Trp. However, L-NAT concentrations in the pooled sera increased at the end of the experiment. Trp (1 mM) decreased the area of human myocytes, similar to IS, whereas L-NAT did not.

Conclusion: L-NAT is a binding competitor with the ability to remove protein-bound IS while preventing sarcopenia.

Introduction: Plasma exchange therapy (PE) is useful for patients with primary macroglobulinemia and multiple myeloma who present with hyperviscosity syndrome. However, hyperviscous blood may coagulate in the circuit during treatment, and in that case necessitate discontinuation of the treatment. This time, we report that we were able to prevent coagulation in the circuit by adding some ideas during the membrane separation method.

Methods: Physiological saline is injected in front of the plasma separation membrane to pre-dilute the blood, followed by filtration through the plasma separation membrane.

Results: As a result of pre-diluting with physiological saline to reduce the viscosity entering the separation membrane, it was possible to process the planned target amount.

Conclusion: In patients with hyperviscosity syndrome who showed intracircuit coagulation during plasma exchange therapy, devising a predilution method should be considered as one of the ways to continue treatment.

Introduction: The purpose of this study was to ascertain the levels of anxiety, despair, avoidance, and obsessions that hemodialysis patients dealt with during the pandemic.

Methods: The study was conducted with 139 hemodialysis patients. Research data "Coronavirus Anxiety Scale (CAS)," "Hospital Anxiety and Depression Scale (HAD)," "COVID-19 Avoidance Scale" (AA-COVID-19) and "Coronavirus Obsession Scale (OCS)." The data obtained from the research were analyzed using the SPSS 21 package program.

Results: The average score of the patients on the CAS scale was 0.73 ± 1.17, on the HAD-A scale was 5.94 ± 3.67, and on the HAD-D scale was 7.06 ± 3.89. The COVID-19 outbreak has consequently had a severe impact on hemodialysis patients' mental health.

Conclusion: Covid 19 epidemic, the health sector failed to protect the mental health of patients. However, new epidemics and disasters await the world in the future. In these results show that new strategies need to be developed.
