objective: to compare immunogenicity of a recombinant hepatitis b (hb) vaccine in two groups of neonates born in two cities of iran with different geographic and ethnic backgrounds. materials and methods: ten micrograms of a recombinant hb vaccine was administered under field condition to iranian healthy neonates at 0, 1.5 and 9 months intervals. the subjects consisted of two groups of 290 an...
background: in spite of available, and sensitive screening assay for detection of hepatitis b virus surface antigen (hbsag), occasional cases of post-transfusion hepatitis b virus infection are still observed. the aim of the present study was to assess the prevalence of positive anti hepatitis b core (anti-hbc) and presence of hbv-dna in serum sample of healthy blood donors negative for both hb...
Through living-donor liver transplantation (LDLT) from a human leukocyte antigen (HLA)-matched sibling donor, it may be possible to stop the use of immunosuppressants. It is that acute antibody-mediated rejection and chronic active through positivity donor-specific anti-HLA antibodies and/or T cell-mediated affect prognosis transplantation. The etiologies diseases recipient also post-transplant...
Human leukocyte antigen (HLA) class I molecules on hematopoietic cancers and melanomas inhibit attack by natural killer lymphocytes, but previous studies have not consistently demonstrated that carcinoma cells are protected by HLA class I expression. We investigated whether HLA class I molecules protect oral and pharyngeal squamous cell carcinoma cells from natural killer lymphocyte attack. Squ...
BACKGROUND Chronic humoral rejection is a progressive form of graft injury, with defined diagnostic criteria, the crucial one being the evidence of circulating anti-donor antibodies. These antibodies are mainly directed against human leucocyte antigens (HLA), but other targets have also been described. We previously reported that antibodies against the Glutathione S-transferase T1 (GSTT1) enzym...
Abstract Not all anti‐HLA donor‐specific antibodies (HLA‐DSAs) are detrimental to renal allograft. In this context, the C1q complement activating ability of appears be an important parameter distinguish clinically inert versus DSAs. We evaluated sera 206 consecutive primary live donor transplant recipients before and at post‐operative day 7, 30, 90, 180 time graft dysfunction for quantifying HL...
Background and Purpose : The prevalence of Hepatitis B in ÜSÂ was reported 0.5- 0.1 % while in Ïran is 1.6- 6.5 %. Ït was reported that the titer of antibody three days after vaccination was 79-90 %. The titer of antibody decreases with the pass of time, and age has a significant role in the respones to vaccination. This study was performed in order to evaluate the HBS titer after vaccination...
BACKGROUND Neonatal alloimmune thrombocytopenia is most commonly due to transplacental passage of maternal anti-HPA 1a antibodies. A prospective study was carried out to evaluate the pattern and quantity of maternal anti-HPA 1a antibodies in order to predict the level of thrombocytopenia in the neonates. DESIGN AND METHODS A monoclonal antibody immobilization of platelet antigen assay was use...
The histopathology of antibody-mediated rejection in lung allografts, outside of classical hyperacute rejection, has been poorly defined, in part because of the difficulty in identifying potential alloantibodies and in separating alloreactive and nonspecific complement-mediated reactions. In this study, we looked at lung biopsies coinciding with the development of anti-human leukocyte antigen (...
We report a 37-year-old female HTLV-I carrier with complicating primary biliary cirrhosis (PBC) and mixed connective tissue disease (MCTD). Serum anti-HTLV-I antibody titer was x256. Flower cells (4.5%) were found in the peripheral blood. Southern blot analysis showed no clonal integration in peripheral blood lymphocyte (PBL) DNA. Polymerase chain reaction showed the HTLV-I genome in PBL DNA. A...
