Novel Application of Extracorporeal Photopheresis as Treatment of Graft-versus-Host Disease Following Liver Transplantation.

A 48-year-old man with hepatitis C virus (HCV) cirrhosis complicated by hepatocellular carcinoma underwent liver transplantation. His course was complicated by fever, diarrhea, abdominal pain, and pancytopenia. He developed a diffuse erythematous rash, which progressed to erythroderma. Biopsies of the colon and skin were consistent with acute graft-versus-host disease. Donor-derived lymphocytes were present in the peripheral blood. The patient was treated with corticosteroids and cyclosporine; however, he had minimal response to intensive immunosuppressive therapy. Extracorporeal photopheresis was initiated as a salvage therapy. He had a dramatic response, and his rash, diarrhea, and pancytopenia resolved. He is maintained on minimal immunosuppression 24 months later.

Intravenous methylprednisolone versus therapeutic plasma exchange for treatment of anti-N-methyl-D-aspartate receptor antibody encephalitis: A retrospective review.

INTRODUCTION: Anti-N-methyl-d-aspartate (NMDA) receptor antibody encephalitis is an increasingly recognized form of autoimmune encephalitis. Conventional treatments include therapies such as corticosteroids, intravenous immunoglobulin (IVIg), and/or therapeutic plasma exchange (TPE). Although TPE is regularly used for treatment of anti-NMDA receptor antibody encephalitis, the American Society for Apheresis has given it a category III recommendation only. Earlier administered immunotherapies in tumor-negative patients may facilitate faster recoveries, but it remains unclear whether or not TPE is superior to steroids and/or IVIG. METHODS: We retrospectively evaluated 10 of 14 patients that received steroids and TPE with modified Rankin scores and subjectively assessed the point of largest sustained improvement in all 14 patients. RESULTS: In the patients that received both steroids and TPE at our institution during the same hospitalization (only 10 of 14 patients), 7/10 patients after TPE had improved with the modified Rankin score versus 3/10 patients after steroids. The average modified Rankin score improvement after steroids in this group was -0.1 as compared with 0.4 after TPE. Based on subjective chart review analysis during which all 14 patients were assessed, the largest sustained improvement occurred immediately following the third-fifth exchange in 9/14 patients, whereas only 2/14 patients appeared to have had significant benefit immediately following steroids. CONCLUSIONS: This is compelling preliminary data that suggests that corticosteroids may not be as effective compared to steroids followed by TPE. Given the importance of time-sensitive treatment, more formal studies may illuminate the ideal first-line treatment for anti-NMDA receptor antibody encephalitis.

Coagulation factor levels in neurosurgical patients with mild prolongation of prothrombin time: effect on plasma transfusion therapy.

OBJECT: Neurosurgical patients often have mildly prolonged prothrombin time (PT) or international normalized ratio (INR). In the absence of liver disease this mild prolongation appears to be due to the use of very sensitive PT reagents. Therefore, the authors performed relevant coagulation factor assays to assess coagulopathy in such patients. They also compared plasma transfusion practices in their hospital before and after the study. METHODS: The authors tested 30 plasma specimens from 25 patients with an INR of 1.3-1.7 for coagulation factors II, VII, and VIII. They also evaluated plasma orders during the 5-month study period and compared them with similar poststudy periods following changes in plasma transfusion guidelines based on the study results. RESULTS: At the time of plasma orders the median INR was 1.35 (range 1.3-1.7, normal reference range 0.9-1.2) with a corresponding median PT of 13.6 seconds (range 12.8-17.6 seconds). All partial thromboplastin times were normal (median 29.0 seconds, range 19.3-33.7 seconds). The median factor VII level was 57% (range 25%-124%), whereas the hemostatic levels recommended for major surgery are 15%-25%. Factors II and VIII levels were also within the hemostatic range (median 72% and 118%, respectively). Based on these scientific data, plasma transfusion guidelines were modified and resulted in a 75%-85% reduction in plasma orders for mildly prolonged INR over the next 2 years. CONCLUSIONS: Neurosurgical patients with a mild prolongation of INR (up to 1.7) have hemostatically normal levels of important coagulation factors, and the authors recommend that plasma not be transfused to simply correct this abnormal laboratory value.

Prospective monitoring of plasma and platelet transfusions in a large teaching hospital results in significant cost reduction.

BACKGROUND: Plasma and platelets (PLTs) are often transfused to correct mild to moderately abnormal laboratory values. Our objective was to reduce unnecessary plasma and PLT transfusions to nonbleeding patients by prospective triage and education of end users in evidence-based hemostasis and transfusion medicine practices. STUDY DESIGN AND METHODS: Using the Parkland Memorial Hospital's transfusion service and admission database as the data source, this study comprises the comparison of transfusion data on plasma and PLT use between pre- (2000-2002) and posttriage (2003-2006) periods. Yearly transfusion and wastage data on red blood cells (RBCs), plasma, and PLTs and yearly hospital admissions, trauma visits, and surgical procedures were extracted retrospectively for the study. RESULTS: The study revealed that implementation of triage resulted in a significant reduction of plasma (60%) and PLT (25%) transfusions, saving more than $3,000,000 over 4 years. CONCLUSIONS: Prospective triage and evidence-based transfusion practice education reduced unnecessary plasma and PLT transfusions and health care costs.
