    Title Evidence-based Practice Guidelines for Plasma Transfusion.
    Date July 2010
    Journal Transfusion
    Excerpt

    There is little systematically derived evidence-based guidance to inform plasma transfusion decisions. To address this issue, the AABB commissioned the development of clinical practice guidelines to help direct appropriate transfusion of plasma.

    Title Platelet Function Testing to Assess Effectiveness of Platelet Transfusion Therapy.
    Date November 2004
    Journal Transfusion and Apheresis Science : Official Journal of the World Apheresis Association : Official Journal of the European Society for Haemapheresis
    Excerpt

    BACKGROUND: Posttransfusion corrected count increments (CCI) following administration of platelets is the standard method for assessing effectiveness of platelet transfusion therapy. However, improvement in platelet count following transfusion may not necessarily indicate improvement in platelet function or restoration of primary hemostatic capacity. To address this possibility, we investigated the effectiveness of platelet transfusion based on results of the Platelet Function Analyzer (PFA-100) and post-transfusion CCI. INVESTIGATION DESIGN AND METHODS: Platelet transfusion requests with different indications received at the blood bank were evaluated for inclusion in the investigation. Pre-transfusion, the following laboratory tests were performed: (1) PFA-100 assays (blood collected in 3.2% buffered sodium citrate) performed with CEPI and CADP test cartridges; (2) complete blood count (in EDTA) and platelet count; and (3) routine coagulation profile including PT, PTT, fibrinogen and D-Dimer. Only patients with normal coagulation profiles were included. The same set of tests were performed on a new blood sample collected 10-60 min post-transfusion. Chart review and clinical evaluation for response to platelet therapy were performed on each occasion of transfusion. RESULTS: Thirty-one patients, five of whom were transfused on more than one occasion were evaluated. Thirty-five transfusion incidents were included. Posttransfusion outcomes were divided into two groups--those that resulted in shortening (>40 s) or normalization of the closure time (Group A) and those that had no change or greater prolongation of the closure time (Group B) when compared to the pre-transfusion value. Seventeen and eighteen transfusion episodes were categorized as Groups A and B, respectively. In Group A with improved PFA testing, nine patients had bleeding as indication for transfusion and six of these had concomitant improvement in their clinical picture as confirmed by control of hemorrhage. In contrast in Group B with no improvement in PFA testing, seven patients had bleeding as indication for transfusion and none showed cessation of hemorrhagic symptoms. These findings were statistically significant (p=0.0114). Similar evaluation using the post-transfusion CCI showed no correlation to bleeding symptoms in these patients (p-=0.500). CONCLUSIONS: In this evaluation, platelet function testing using the PFA-100 provided a better indication of transfusion outcome than did the post-transfusion CCI. Using this approach, PFA-100 may be an effective aid for supporting platelet transfusion decisions and may further aid in improving management of the hospital blood bank platelet inventory.

    Title Treatment of Plasma Refractory Thrombotic Thrombocytopenic Purpura with Protein A Immunoabsorption.
    Date July 1997
    Journal American Journal of Hematology
    Excerpt

    The objective of this study was to assess the effect of protein A immunoabsorption in terms of response rate and toxicities in patients with classical thrombotic thrombocytopenic purpura (TTP) refractory to therapeutic plasma exchange. The study included nine females and one male with a diagnosis of classical TTP treated at multiple university hospital centers with protein A immunoabsorption (PAI) after having failed plasma exchange. The 10 patients had an age range 17-62 years. Prior to PAI, the patients had failed to respond to a mean of 15 (range 6-39) therapeutic plasma exchanges. Three patients had previous episodes of TTP. Evaluation for response to PAI included serial measurements of serum creatinine, lactate dehydrogenase (LDH), hemoglobin, hematocrit, and platelet count before, during, and up to 18 months post-PAI treatment. Seven of 10 study patients had resolution of their TTP. Six of the patients required six or fewer therapeutic PAIs and one required 12 treatments. All responding patients had evidence of improvement by the third PAI treatment. Three patients demonstrated no response to PAI, with two patients expiring from complications of TTP and one patient demonstrating a complete response to a subsequent therapy. No significant toxicity was noted with the use of PAI in this setting. Protein A immunoabsorption in patients with classical TTP refractory to plasma exchange can produce durable complete remissions and warrants comparative studies.

    Title An Introductory Orientation to Clinical Pathology Core and On-call Responsibilities.
    Date June 1994
    Journal Archives of Pathology & Laboratory Medicine
    Excerpt

    An introductory 4-week orientation for clinical pathology is described. There were 76 hours of lectures, 74 hours of conferences, and 68 hours of laboratories for a total of 221 hours. During the orientation, all calls handled by the residents were evaluated as to resolution, patient outcome, and interaction required. Eighty calls were received during the orientation from 57 technologists (71%), 16 physicians (20%), and seven nurses (9%). The calls originated concerning the following: blood banking, 37 (46%); hematology, 21 (27%); chemistry, 14 (18%); microbiology, five (6%); and administration, three (4%). Sixty percent of the calls were consultative and 40% were supervisory. Ninety-nine percent were handled appropriately by the residents. Patient outcome was moderately or significantly affected in 44% of all calls, divided between 67% of all consultative calls and 9% of all supervisory calls. Significant pathologist interaction was required in 49% of all calls, divided between 71% of the consultative calls and 16% of the supervisory calls. Using this integrated, dynamic system of resident instruction, on-call experience, and evaluation, residents quickly gain confidence in handling call, didactic clinical consultation, and patient management. The orientation and on-call system described provides for a relevant and dynamic system for resident education.
