OBJECTIVES: To study the role of plasma exchange combined with continuous blood purification in the treatment of refractory Kawasaki disease shock syndrome (KDSS). METHODS: A total of 35 children with KDSS who were hospitalized in the Department of Pediatric Intensive Care Unit, Hunan Children's Hospital, from January 2019 to August 2022 were included as subjects. According to whether plasma exchange combined with continuous veno-venous hemofiltration dialysis was performed, they were divided into a purification group with 12 patients and a conventional group with 23 patients. The two groups were compared in terms of clinical data, laboratory markers, and prognosis. RESULTS: Compared with the conventional group, the purification group had significantly shorter time to recovery from shock and length of hospital stay in the pediatric intensive care unit, as well as a significantly lower number of organs involved during the course of the disease (P<0.05). After treatment, the purification group had significant reductions in the levels of interleukin-6, tumor necrosis factor-α, heparin-binding protein, and brain natriuretic peptide (P<0.05), while the conventional group had significant increases in these indices after treatment (P<0.05). After treatment, the children in the purification group tended to have reductions in stroke volume variation, thoracic fluid content, and systemic vascular resistance and an increase in cardiac output over the time of treatment. CONCLUSIONS Plasma exchange combined with continuous veno-venous hemofiltration dialysis for the treatment of KDSS can alleviate inflammation, maintain fluid balance inside and outside blood vessels, and shorten the course of disease, the duration of shock and the length of hospital stay in the pediatric intensive care unit.

OBJECTIVE: To compare the effects of artificial liver treatment with double plasma molecular adsorption system(DPMAS) mode and traditional plasma exchange (PE) mode on platelets in patients, and to evaluate the clinical efficacy of recombinent human thrombopoietin (rhTPO) in the treatment of thrombocytopenia. METHODS: A total of fifteen patients undergoing artificial liver with DPMAS model admitted to the Fifth Affiliated Hospital of Guangzhou Medical University from January 2018 to November 2020 were selected and included in the DPMAS group, and another 15 patients receiving PE were selected and included in the PE group. The improvement of clinical symptoms, such as fatigue, jaundice, oliguria, edema, etc. before and after artificial liver treatment was compared between the two groups, and the trend of blood routine (especially platelet), coagulation function and other indexes before and after treatment were compared between the two groups. The use of rhTPO and the number of platelets were recorded during treatment. RESULTS: The improvement rate of clinical symptoms in DPMAS group was 86.67%, which was higher than that in PE group, but the difference was not statistically significant (P>0.05). There was no statistical significance in the outcome of the two groups within 90 days (P>0.05). There was no significant difference in white blood cell (WBC) and hemoglobin (HB) between the two groups after treatment (P>0.05). However, the level of platelet(PLT) in DPMAS group was significantly lower than that before treatment (P < 0.05), and was significantly lower than that in PE group (P < 0.05). After treatment, the international normalized ratio (INR) level in PE group was significantly improved (P < 0.05), but there was no significant difference in the INR level in DPMAS group (P>0.05). The patients in the DPMAS group received an average of (8.2±3.1) doses of rhTPO and (1.5±0.3) IU of platelet transfusions during hospitalization. In DMPAS group, platelets increased significantly after infusion of terbium. CONCLUSION Compared with PE mode, the artificial liver with DPMAS mode can reduce platelet levels in patients, but the application of rhTPO can stimulate platelet regeneration and increase platelet levels in the patients, thereby reducing the risk of bleeding due to platelet hypoplasia.

OBJECTIVES: To investigate the efficacy and application value of plasma exchange as an adjuvant therapy in children with hemophagocytic syndrome (HPS). METHODS: A prospective randomized controlled trial was designed. Forty children with severe HPS were enrolled, who were treated in the pediatric intensive care unit (PICU) of Hunan Children's Hospital from October 2018 to October 2020. The children were randomly divided into a plasma exchange group and a conventional treatment group using a random number table, with 20 children in each group. The children in the conventional treatment group received etiological treatment and conventional symptomatic supportive treatment, and those in the plasma exchange group received plasma exchange in addition to the treatment in the conventional treatment group. The two groups were compared in terms of general information, clinical symptoms and signs before and after treatment, main laboratory markers, treatment outcome, and prognosis. RESULTS: Before treatment, there were no significant differences between the two groups in gender, age, course of the disease before admission, etiological composition, pediatric critical illness score, involvement of organ or system functions, and laboratory markers (P>0.05). After 7 days of treatment, both groups had remission and improvement in clinical symptoms and signs. After treatment, the plasma exchange group had significantly lower levels of C-reactive protein, procalcitonin, and serum protein levels than the conventional treatment group (P<0.05). The plasma exchange group also had significantly lower levels of alanine aminotransferase and total bilirubin than the conventional treatment group (P<0.05). The length of stay in the PICU in the plasma exchange group was significantly shorter than that in the conventional treatment group (P<0.05). The plasma exchange group had a significantly higher treatment response rate than the conventional treatment group (P<0.05). There were no significant differences between the two groups in the total length of hospital stay and 3-month mortality rate (P>0.05). CONCLUSIONS Plasma exchange as an adjuvant therapy is effective for children with severe HPS. It can improve clinical symptoms and signs and some laboratory markers and shorten the length of stay in the PICU, and therefore, it may become an optional adjuvant therapy for children with severe HPS.

Thrombotic thrombocytopenic purpura (TTP) is a thrombotic microangiopathy, in which a severe deficiency of von Willebrand factor lyase results in thrombocytopenic clots that block blood vessels and eventually lead to terminal organ failure. Therapeutic plasma exchange is the cornerstone of TTP treatment which can greatly improves the survival rate of the patients. With the further exploration to the pathophysiological mechanism of TTP, other alternative therapies, new immunosuppressive agents, targeted antagonists, gene therapy and other emerging means gradually emerge, which are expected to further reduce the mortality and recurrence rate of the patients. In this review, the new developments in TTP treatment were summarized briefly.

OBJECTIVES: To study the indication for therapeutic plasma exchange (TPE) and related complications in children admitted to the pediatric intensive care unit. METHODS: A retrospective analysis was performed on the medical records of the children who received TPE in the Pediatric Intensive Care Unit, Hunan Children's Hospital, from March 2015 to March 2021. The indication for TPE and related complications were analyzed and compared with the American Society for Apheresis (ASFA) indication categories. RESULTS: A total of 405 TPE treatment sessions were performed for 196 children, among whom 76 children (38.8%) also received continuous renal replacement therapy and 147 children (75.0%) survived. The children with neurological diseases had the highest survival rate of 93.1% (27/29). The top three indications for TPE were hematologic diseases (61/196, 31.1%), sepsis with multiple organ dysfunction (41/196, 20.9%), and liver diseases (36/196, 18.4%). The children with hematologic diseases received the highest number of 129 TPE treatment sessions. The subjects with ASFA category Ⅲ indications accounted for the highest proportion of 76.5% (150/196), followed by those with ASFA category Ⅰ indications (11.2%, 22/196), ASFA category Ⅱ indications (7.1%, 14/196), and unknown category (5.1%, 10/196), and no ASFA category Ⅳ indications were observed. The incidence rate of TPE complications was 12.3% (50/405), and the most common complications were pipeline coagulation (4.2%, 17/405) and hypotension (3.7%, 15/405). No serious adverse events were observed. CONCLUSIONS TPE can be safely used for the treatment of critically ill children with indications in an experienced pediatric intensive care unit.

OBJECTIVE: To observe the efficacy of plasma exchange in the treatment of patients with immune thrombocytopenic purpura (ITP), and to analyze the factors influencing the efficacy of plasma exchange in the treatment of ITP. METHODS: The medical records of 39 ITP patients who were treated effectively by plasma exchange in Huai'an First People's Hospital from January 2013 to January 2021 were retrospectively analyzed, and they were set as the effective group. In addition, the medical records of 39 ITP patients who were treated ineffective by plasma exchange during the same period in our hospital were collected, and they were set as the ineffective group. The general data such as sex and age of patients and laboratory indicators on admission were collected and recorded. The possible influencing factors were included, and Logistic regression analysis was used to examine the influencing factors of efficacy of plasma exchange in the treatment of ITP. RESULTS: The serum levels of IL-6, IL-18 and B lymphocyte activating factor (BAFF) on admission in the ineffective group were significantly higher than those in the effective group, and the proportions of Helicobacter pylori (HP) infection and splenomegaly were significantly higher than those in the effective group (P<0.05). There was no statistical significantly difference in sex, age and other data between the two groups (P>0.05). After single factor analysis, multiple regression model was established, which showed that splenomegaly, HP infection and the over expression of serum IL-6, IL-18 and BAFF on admission might be the influencing factors of ineffective treatment of ITP by plasma exchange (OR>1, P<0.05). CONCLUSION The over expression of serum IL-6, IL-18, BAFF, splenomegaly and HP infection on admission may be the influencing factors resulting in the ineffective treatment of plasma exchange in ITP.

This report presents the case of a 59-year-old man with severe COVID-19 that gradually progressed to cytokine release syndrome and then acute respiratory distress syndrome; he was successfully treated via integration of therapeutic plasma exchange and traditional Chinese medicine. The patient initially presented with a sore throat, severe muscle aches, productive cough and fever. On the worsening of symptoms, remdesivir was administered. However, as the symptoms continued to worsen and a cytokine release syndrome was suspected, oxygen was provided through a high-flow nasal cannula (50 L/min) and therapeutic plasma exchange was performed to prevent worsening of the acute respiratory distress syndrome. On the same day, a course of traditional Chinese medicine was introduced in consultation with the infectious house staff. The patient's symptoms gradually improved; the levels of C-reactive protein and D-dimers reduced, and the patient was weaned to a simple oxygen mask and eventually to room air. This is the first reported case of the integration of these treatments. Together, they prevented the patient from requiring intubation, played a role in cytokine management, and also improved the clinical symptoms, including productive purulent sputum, cough, frequent stool passage and intermittent fever, with no adverse effects. As a result, the patient was discharged within two weeks of the integration of these treatments. Therefore, the integration of therapeutic plasma exchange and traditional Chinese medicine is an effective therapy for patients with severe COVID-19.
