Autologous blood donor screening indicated a lower prevalence of viral hepatitis in East vs West Germany: epidemiological benefit from established health resources.

Prevalence data concerning viral hepatitis and human immunodeficiency virus (HIV) in the general population are usually scarce. We aimed for a large cohort representative of the general population that required little funding. Autologous blood donors are relatively representative of the general population, and are tested for viral hepatitis and HIV in many countries. However, frequently these data are not captured for epidemiologic purposes. We analysed data from well over 35,000 autologous blood donors as recorded in 21 different transfusion centres for anti-hepatitis C virus (HCV), HBsAg and anti-HIV, as well as TPHA if available. We found a lower prevalence of hepatitis B virus and HCV in East vs West Germany, 0.2%vs 0.32% and 0.16%vs 0.32% respectively, which confirms earlier data in smaller cohorts, thus supporting the value of our approach. HIV was too rare to disclose significant differences, 0.01%vs 0.02%. TPHA was higher in East (0.34%) vs West Germany (0.29%) without significant differences. HCV was more frequent in women vs men. Transfusion institutes managing autologous blood donations should be used as a resource for epidemiological data relating to viral hepatitis and HIV, if such testing is performed routinely. This approach generates data relating to the general population with special emphasis on undiagnosed cases.

Efficacy and safety of G-CSF mobilized granulocyte transfusions in four neutropenic children with sepsis and invasive fungal infection.

BACKGROUND: Bacterial and fungal infections are serious complications of cancer therapy. Especially during longstanding neutropenia, patients are at risk for life-threatening infections. The aim of this study was to assess the effect and safety of G-CSF mobilized granulocyte transfusions (GTX) in four neutropenic pediatric patients with sepsis. PATIENTS AND METHODS: The patients were between 4.6-17.5 years old and their diagnoses included very severe aplastic anemia, non-Hodgkin's lymphoma (NHL) and acute myeloid leukemia. Before GTX, all patients had fever despite antibiotic and antimycotic therapy, neutropenia (absolute neutrophil count ANC < 500/microl), increasing C-reactive protein (CRP) values, hypotension requiring dopamine infusion and three patients needed supplemental oxygen. The granulocyte donors received G-CSF (Neupogen, 5 microg/kg body weight) 12 h prior to granulocyte apheresis. RESULTS: In total, 40 GTX were performed (range 2-28 per patient). The mean increase of the granulocyte count 1 h after GTX was 1,310/microl (range 200-2,950/microl). Within the period of GTX the CRP values decreased in all patients. During or 24 h after the last GTX, the hypotension resolved and supplemental oxygen was stopped. One GTX was discontinued because of oxygen desaturation. CONCLUSION: GTX were a safe therapeutic measure with beneficial effects on serious infections in neutropenic children.
