[The epidemiological trends connected with detection of HIV, HCV, HBV and syphilis markers in blood donors in the years 2006-2009]. / Trendy epidemiologiczne zwiazane z wykrywaniem markerów zakazenia HIV, HCV, HBV i kily u dawców krwi w latach 2006-2009.

UNLABELLED: In the recent years a great progress has been documented in infection prevention. There is more possibilities responsible for infection and its transmission. THE AIM OF THE STUDY: To analyze obtained epidemiological data concerned to detected infection in blood donors in the area of Blood Bank in Katowice in the years 2006-2009. MATERIAL AND METHODS: Statistic calculations taking account of confirmed infections in the years 2006-2009 were analyzed in first-time donors and multiple donors, and for all donors. RESULTS: Tests confirming infection were performed in the IHiT in Warsaw, in RBC in Katowice, confirmation test for syphilis in the RBC in Warsaw. Only the positive confirmed results are taken into account and presented in summary. In first-time donors more frequently the markers of infection: HCV and HBV dozens of times, HIV and syphilis several times were detected. In the group of first-time donors a downward trend was detected in the number of detected infections HBV and HCV In the group of multiple donors the downward trend was documented in the number of detected antibodies associated to syphilis. In the group of multiple donors the number of detected HIV infections has been increased in the years 2008 and 2009. CONCLUSIONS: For monitoring trends of each type of infections, a period of four-years is not sufficiently long. This data needs a further observations.

The adverse transfusion reaction is usually defined as an unwanted reaction occurring in a recipient during or after a blood transfusion or its components. Adverse reaction can occur even in 10% of recipients. The after transfusion reactions can be divided with regard to its causes: infectious and non-infectious, of immunologic and non-immunologic.

[Leukapheresis in children with chronic myeloid leukemia and pulmonary leukostasis]. / Leukafereza u dzieci chorych na przewlekla bialaczke szpikowa z objawami leukostazy plucnej.

We present two patients with chronic myeloid leukemia and hyperleukocytosis above 350 x 10(9)/l causing the symptoms of pulmonary leukostasis. Therapeutic leukapheresis procedures with concomitant chemotherapy were initiated within 12 hours from the diagnosis. After the therapy commencement the general condition of the patients systematically improved and leukocytosis gradually decreased from the second day of treatment with disappearance of pulmonary leukostasis symptoms. Thanks to application of such treatment procedures during the cytoreductive period, severe complications related to leukostasis could be prevented.
