    Notes: [Auszug] SIR-"Why aren't horses faster?" asks W. G. Hill in his comment1 on the study by Gaffney and Cunningham2 of a genetic trend in thoroughbred horse-racing performance. We suggest here that today's horses are faster and still improving, if only marginally. Figure 1 in the paper by Gaffney and ...

    Notes: Summary Optimal labelling conditions of human platelets with111In-oxine were determined in vitro. Based on this optimized technique, platelet mean life span (MLS) and platelet sequestration site were comparatively evaluated in 79 patients with two labels,51Cr (n=26) and111In (n=53). Patients were subgrouped according to clinical criteria as autoimmune thrombocytopenic purpura (AITP) (group 1;n=49), hypersplenism (2;n=12), impaired thrombopoiesis (3;n=3), unclassified thrombocytopenia (4;n=6), and nonthrombocytopenic patients (5;n=9). In patients with AITP and hypersplenism the mean values for the MLS determined either with51Cr or with111In were lowered but the difference was not statistically significant, neither for group 1 (18.6 h vs 17.3 h;P〉0.2) nor for group 2 (94.7 vs 122.3 h;P〉0.2). The correlation between MLS and platelet counts in patients with AITP was significant for both labels (P〈0.001). The 15 min recovery tended to be higher with111In in all groups, but the difference was significant (P〈0.05) only for group 1. The sequestration sites were similar with both labels. We conclude that, contrary to previous reports, platelet survival studies yield similar results with both the51Cr and111In methods. Due to its distinct advantages111In is the label of choice for investigation of platelet kinetics.

    Notes: Summary Thirteen cases of posttransfusion purpura (PTP) which were diagnosed in Germany and Austria from 1977–1985 are described. All patients were women with a mean age of 58.6 years (range, 36–77 years). All but one had been pregnant and received blood transfusions 2 to 12 days prior to the onset of PTP. The thrombocytopenic purpura was always severe with a nadir of platelet counts below 10×109/l and lasted between 3 and 60 days. All patients recovered from PTP. Optimal therapy consisted of administration of high-dose IgG. Twelve of the 13 patients had developed platelet-specific Zwa antibodies (eight of them together with HLA antibodies), in one Zwa positive individual only HLA antibodies were detectable. Five of six HLA-DR typed patients carried DR3 which is considered an immunogenetic risk factor in PTP. Clinical awareness of this rare, but serious iatrogenic transfusion complication is prerequisite for prompt diagnosis and improved therapy.

    Description / Table of Contents: Summary Two patients with post-transfusion thrombocytopenic purpura are described, the first cases recognized in Austria and Germany. Both patients were female, 51 and 60 years of age. The purpura was evoked by blood transfusions with a latent period of 2 and 7 days. The thrombocytopenic episode lasted for 22 and over 60 days. In one case, thrombocytopenia was associated with agranulocytosis due to transient bone marrow failure. Both patients were negative for the platelet-specific antigen PlA1 (= Zwa). Their sera contained PlA1 as well as potent HLA antibodies. Detailed clinical and serological data are presented. The literature with a total of 25 cases so far reported is surveyed.
    Notes: Zusammenfassung Es werden die ersten beiden Patienten mit posttransfusioneller thrombozytopenischer Purpura beschrieben, die in Österreich und in Deutschland diagnostiziert werden konnten. Beide Patienten waren Frauen im Alter von 51 und 60 Jahren. Die Purpura wurde durch Bluttransfusionen ausgelöst mit einer Latenzzeit von zwei bzw. sieben Tagen. Die thrombozytopenische Phase dauerte 22 bzw. länger als 60 Tage. In einem Fall bestand neben der Thrombozytopenie eine Agranulozytose infolge einer vorübergehenden Knochenmarksinsuffizienz. Beide Patienten waren negativ für das thrombozytenspezifische Antigen PlA1 (= Zwa). Ihr Serum enthielt sowohl PlA1- als auch starke HLA-Antikörper. Die klinischen und serologischen Befunde beider Patienten werden eingehend dargestellt. Eine Literaturübersicht mit bisher 25 beschriebenen Fällen ist angefügt.

    Description / Table of Contents: Summary The role of platelet alloimmunization in the survival of51Cr-labeled allogeneic platelets was investigated in 89 patients with severe thrombocytopenias. The serological analysis included HLA typing of patients, screening of their sera in the lymphocytotoxicity test (LCTT), the platelet complement fixation test(PCFT), and the platelet radioactive anti-IgG test (PRAT; N=38). Platelet donors were selected according to the best available HLA match and crossmatch in LCTT. Alloantibodies against HLA antigens were found in the sera of 17 patients (19.1%). No platelet-specific alloantibodies were detected. The use of compatible, allogeneic platelets permitted the discrimination of diminished platelet production from increased platelet turnover in thrombocytopenic patients with proven alloimmunization. Our results stress the necessity of a serological workup prior to platelet survival studies.
    Notes: Zusammenfassung Bei 89 Patienten mit hochgradigen Thrombozytopenien wurde der Einfluß einer möglichen Alloimmunisierung gegen Thrombozytenantigene auf die Bestimmung der Überlebenszeit von51Cr-markierten, allogenen Thrombozyten untersucht. Die serologische Analyse stützte sich auf die HLA-Typisierung der Patienten, Antikörpersuche im Lymphozytotoxizitätstest (LCTT), Plättchen-Komplementfixationstest (PCFT) und Plättchen-Radioimmun-Anti-IgG-Test (PRAT; N=38). Die Spenderauswahl erfolgte nach bestmöglicher Übereinstimmung der HLA-Antigene und dem crossmatch im LCTT. Bei 17 Patienten (19,1%) wurden Alloantikörper gegen HLA-Antigene, in keinem Fall thrombozytenspezifische Alloantikörper nachgewiesen. Durch HLA-kompatible Spenderauswahl war es möglich, auch bei nachweisbar vorimmunisierten thrombozytopenischen Patienten Bildungsvon Umsatzstörungen abzugrenzen. Diese Befunde weisen auf die Notwendigkeit serologischer Voruntersuchungen bei Überlebenszeitstudien mit allogenen Thrombozyten hin.
