Retrospective observational study of changes in serum cytokines and adiponectin with continuous plasma exchange with dialysis therapy for severe COVID-19.

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.

Application of Traditional Japanese Drug Jidabokuippo in a Modern Society.

Background: Jidabokuippo (JDI) () has been used in Japan to alleviate contusion-induced swelling and pain since medieval times. Method: This review investigated the effects of JDI on various symptoms in patients with trauma or static blood[TM1]. The PubMed and Igaku Chuo Zasshi databases were searched until 24 December 2021. We summarize the benefits of applying JDI to inflammatory conditions, including bruises. Results: JDI has been used to resolve blood [TM1] stasis, regulate qi in trauma patients, and treat inflammatory swelling and pain caused by rheumatoid arthritis and cellulitis. As the adverse event rate associated with JDI is low (1.3%), JDI is considered a safe drug. Conclusion: JDI can be used to resolve blood[TM1] stasis in trauma patients without adverse events associated with nonsteroidal anti-inflammatory drugs.

Continuous plasma exchange with dialysis for thrombotic microangiopathy in intensive care unit: Retrospective observational study.

Continuous plasma exchange with dialysis is a novel method of blood purification and is a modification of the plasma exchange. Technically, this process suggests a reduction in adverse events, cost-effectiveness, and compatibility with hemodynamic instability. The therapeutic effect of plasma exchange on thrombotic microangiopathies has been established. We present three clinical cases in the intensive care unit that illustrate continuous plasma exchange with dialysis as a flexible blood purification therapy for critically ill patients; a radical treatment, thrombotic microangiopathies; supportive therapy, multiple organ failure; and fluid balance regulator. The retrospective analysis of 13 continuous plasma exchange with dialysis sessions showed that the platelet count increased significantly (p = 0.0096) after its administration. The total protein, albumin, fibrinogen, or calcium did not decrease significantly after continuous plasma exchange with dialysis, suggesting therapeutic efficacy and fewer adverse events. A prospective study on thrombotic microangiopathies for continuous plasma exchange with dialysis is currently underway.

Continuous Plasma Exchange With Dialysis for Severe Sepsis: Case Series of a Novel Blood Purification Method.

Sepsis is associated with life-threatening organ dysfunction. Drastic treatment methods such as antimicrobials and surgical control have been used to manage sepsis. However, there are currently no other sepsis-specific treatments capable of improving mortality rates. Plasma exchange (PE) for the removal of toxic substances and the replacement of consumed bioprotective proteins has been advocated as a potential treatment for sepsis. Although the evidence for the efficacy of PE for sepsis is quite limited, in a recent finding, sepsis patients treated with PE showed improvement in fluid balance and organ damage. Continuous PE with dialysis (cPED), which is a modified version of PE, is a novel blood purification method. cPED is a combination of selective PE and hemodialysis and operates slowly in a simple circuit that can potentially provide powerful supportive care for patients with multiple organ failure. In this report, we present two cases of treatment with cPED in patients with severe sepsis and organ damage. Both patients were discharged alive without any adverse events from cPED. cPED improved fluid balance as well as laboratory parameters that had reflected multiple organ failure. This suggests a possible reduction in side effects such as leakage of bio-essential proteins and citric acid reactions to large doses of fresh frozen plasma. The clinical course of these two patients may be useful for setting outcomes in future clinical studies regarding the effectiveness of cPED for severe sepsis.

A case of cardiac arrest due to a ruptured renal artery pseudoaneurysm, a complication of renal biopsy.

Renal artery pseudoaneurysms (RAPs) are a rare complication of percutaneous kidney biopsies that generally present as hematuria and back pain and are treated with angioembolization. A 60-year-old man was admitted to our emergency department for sudden left back pain. He was taking an oral anticoagulant for atrial fibrillation. He had undergone an ultrasound-guided percutaneous renal biopsy 26 days prior. We diagnosed him with hemorrhagic shock from the renal artery. Although he received a massive rapid blood transfusion, he went into cardiac arrest. Resuscitative endovascular balloon occlusion of the aorta (REBOA) was performed and, within 10 min, the patient achieved return of spontaneous circulation and regained consciousness. Subsequently, angioembolization was successfully performed for a 12.5 mm × 5.9 mm pseudoaneurysm in the left renal inferior pole close to the site of the renal biopsy. A total of 1680 mL of red blood cells and fresh frozen plasma were administered respectively until hemostasis was completed. He was then treated with continuous hemodialysis in the intensive care unit (ICU) for 6 days. He stayed in the ICU for 9 days and was moved to the general ward with full neurological recovery and a sufficiently stable condition to be able to walk. In conclusion, clinicians should be aware of the possibility of severe hemorrhagic shock due to RAPs after renal biopsy. Moreover, even if the patient goes into cardiac arrest, there is a possibility of full recovery if REBOA is performed and angioembolization is completed.

A Case of Fatal Asthma: Rapid Transition to Cardiac Arrest and Rapid Recovery of Respiratory Status.

The global mortality of bronchial asthma continues to decrease, with a reported 57% decline in age-standardized mortality rates between 1993 and 2006.Asthma may rarely be encountered as a cause of cardiac arrest on arrival in the emergency department these days, especially in high-income countries. Rapid worsening of symptoms and rapid improvement in respiratory status after initiation of treatment have been noted as a hallmark of cardiac arrest due to asthma. A 62-year-old male was admitted to our emergency department after dyspnea and dry coughing attack lasting approximately 15 minutes and resulted in cardiopulmonary arrest. His arterial blood gas analysis showed mixed acidosis with pH 7.00, partial pressure of oxygen (PaO2) 184, partial pressure of carbon dioxide (PaCO2) 90 mmHg, HCO3 - 22.2, lactate 104 mg/dL. He returned to spontaneous circulation after about 30 minutes of cardiopulmonary arrest. The very slight wheeze on expiration was heard in the left lung and his chest x-ray showed increasing permeability of the lung, which suggested air trapping. Based on his history of asthma, the background of medication discontinuation, and physical findings, the diagnosis of cardiac arrest due to an asthma attack was made. Two hours after admission, PaCO2 normalized and his respiratory condition stabilized rapidly. However, epileptic seizures due to hypoxic encephalopathy were prolonged. Although he was then managed in the intensive care unit, he was diagnosed with irreversible brain damage due to hypoxic encephalopathy and shifted to palliative care. Asthmatic cardiac arrest is now rare, but still important. And it may be difficult to identify asthma as a cause of cardiac arrest if the respiratory status improves rapidly. Therefore, keeping in mind the presence of asthma cases of rapid deterioration to cardiopulmonary arrest and case of rapid treatment response may lead to a correct diagnosis.

[A case of simultaneous bilateral metastatic ovarian tumor of colon cancer followed by FOLFOX4 Regimen and oral tegafur/uracil+oral leucovorin after R0 operation].

The patient was a 41-year-old female, who underwent histectomy and sdnexopexy due to perforated ovarian tumor. One month later, she was diagnosed with simultaneous bilateral metastatic ovarian tumor of colon cancer, and right hemicolectomy (D3) was performed. After surgery, the patient was treated with 10 courses of therapy with the FOLFOX4 regimen. No recurrence was recognized, and the patient was treated with 12 courses of therapy with oral tegafur/ uracil (UFT)+oral Leucovorin (LV). The patient evidenced no tumor recurrence 2 years after the initial treatment. We consider oral UFT+oral LV therapy was useful for post FOLFOX4 therapy after R0 surgery.
