Plasma exchange as rescue therapy in multiple organ failure including acute renal failure.

OBJECTIVE: To describe the outcome of using a rescue therapy including plasma exchange given to patients with a progressive acute disseminated intravascular coagulation and multiple organ dysfunction syndrome. STUDY DESIGN: Retrospective study. SETTING: University and county hospital. PATIENTS: Included were 76 consecutive patients (41 men and 35 women) treated with plasma exchange as rescue therapy besides optimal conventional therapy during a progressive course of disseminated intravascular coagulation and multiple organ dysfunction syndrome, including acute renal failure. Of the 76 patients, 66% needed dialysis. The distribution was hemodialysis in 76%, continuous arteriovenous hemofiltration in 36%, continuous venovenous hemodialysis in 12%, and peritoneal dialysis in 24%. The median organ-failure score was 5 (range, 1-6). Seventy-two percent required mechanical ventilation; septic shock was present in 88%. The median septic shock score was 4 (range, 2-4). Nine patients had another reason than sepsis for the multiple organ dysfunction syndrome. INTERVENTION: Plasma exchange (centrifugation technique) was performed until disseminated intravascular coagulation was reversed (median, two times; range, 1-14). Besides antibiotics and fluid administration, most patients received heparin or low molecular weight heparin (77%), steroids (87%), and inotropes (88%). More than one vasoactive drug was used in 57% of the patients. MEASUREMENTS AND MAIN RESULTS: Eighty-two percent of the patients survived and could leave the hospital. The previously observed survival rates by others for this category of patients would be <20%, and thus, the outcome in this study is significantly better. CONCLUSION: Plasma exchange using plasma as replacement may, in addition to conventional intensive care, help to reverse severe progressive disseminated intravascular coagulation and multiple organ dysfunction syndrome and improve survival.

Disseminated intravascular coagulation in patients with multiple organ failure of non-septic origin.

Disseminated intravascular coagulation (DIC) and associated multi-organ failure are serious and often terminal events of a variety of non-septic conditions. For the most part, these conditions are a result of tissue factor (thromboplastin) release from damaged tissues creating situations that favor thrombin formation. Thrombin's role in this process is critical and serves to induce the coagulopathy, as well as many of the other aspects of inflammation that contribute to the associated morbidity and mortality. Clinical disorders giving rise to DIC fall into categories of trauma, obstetrical complications, malignancies and a variety of inflammatory conditions. Diagnostic patterns for these disorders are well established with an expected decrease in platelets and fibrinogen, as well as antithrombin III, in addition to elevated levels of thrombin-antithrombin III complex, prothrombin fragment 1 + 2, and D-dimer; all of which serve to identify the hypercoagulable state. Management of these coagulopathies requires attention to the bleeding diathesis and the ongoing thrombotic complication. Supportive therapy usually is required to provide hemostasis. However, control of the coagulopathy is of equal importance and requires not only early intervention, but also administration of sufficient antithrombotic agents to reduce thrombin's ability to consume coagulation factors, as well as to stimulate inflammatory processes. Heparin has been employed effectively in many of these situations, but suffers from its potential to induce hemorrhage. Antithrombin III concentrate, however, is devoid of this risk and provides a unique alternative that has had a limited, but effective record of benefits. Further proof of its efficacy in multi-organ failure disorders is awaited.
