Potential value of autoantibodies as biomarkers of chronic graft-versus-host disease after allogeneic stem cell transplantation / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

We investigated the value of autoantibodies as biomarkers of chronic graft-versus-host disease (cGVHD) by analyzing the autoantibody profiles of 65 patients (34 cGVHD and 31 non-cGVHD) surviving longer than three months after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Autoantibodies to at least one antigen were detected in 45 patients (70.8%), with multiple autoantibodies detected in 30 patients (46.2%). Antinuclear antibodies (ANAs) were the most frequently detected autoantibodies, with a significantly higher prevalence in non-cGVHD patients and cGVHD patients than that in healthy controls (HCs). ANA-nucleolar (ANA-N) was the main immunofluorescence pattern of ANA-positivity in both the non-cGVHD and cGVHD groups. There was a higher prevalence of anti-Ro52-positivity in non-cGVHD and cGVHD patients than in HC. Liver cGVHD was significantly associated with anti-Ro52-positivity. However, cGVHD activity and severity were not associated with the presence of autoantibodies. Similarly, there were no significant differences in overall survival or relapse among the four groups of patients expressing autoantibodies. Our results suggest that autoantibodies have limited value in predicting cGVHD.

The study on high-resolution HLA and human cytomegalovirus (HCMV) viremia in bone marrow transplantation recipients / 中华实验和临床病毒学杂志

<p><b>OBJECTIVE</b>To study the correlation between high-resolution HLA-A * 1101, HLA-A * 0201, HLA-A * 2402, HLA-B * 4001, HLA-DRB1 * 0901 with HCMV pp65 antigenemia after bone marrow transplantation (BMT) in China.</p><p><b>METHODS</b>48 recipients doing BMT during 2009. 2-2010. 10 were selected in my hospital; HCMV pp65 was detected by ELISA or immunohistochemical methods. The frequency of HLA-A * 1101, HLA-A * 0201, HLA-A * 2402, HLA-B * 4001, HLA-DRB1 * 0901 alleles were determined by Polymerase chain reaction-sequence based typing (PCR - SBT).</p><p><b>RESULTS</b>(1) The BMT recipients were HCMV pp65 antigenic positive(100%); (2) The positive rate of HLA-A * 1101, HLA-A * 0201, HLA-A * 2402, HLA-B * 4001 showed no obvious difference between 12 lower antigenemia group and 36 higher antigenemia group, the positive rate: HLA-A * 1101 were 33.3% (8/24) and 20.8% (15/72), HLA-A * 0201 were 4.2% (1/24) and 13.9% (10/72), HLA-A * 2402 were 12.5% (3/24) and 19.4% (14/72), HLA-B* 4001 were 16.7% (4/24) and 12.5% (9/72); (3) HLA-DRB1 * 0901 positive rate in higher antigenemia group was higher than the lower (P = 0.048), the positive rate were 4.2% (1/24) and 19.4% (14/72); (4) HLA-DRB1 * 0901 recipients were higher pp65 antigenemia than HLA-A * 2402 recipients (P = 0.007) and HLA-A * 1101 recipients (P = 0.028), HLA-A * 0201 recipients were higher pp65 antigenemia than HLA-A * 2402 (P = 0.02), the pp65 antigenemia showed no obvious difference among the rest of high-resolution HLA groups (P > 0.05).</p><p><b>CONCLUSION</b>HLA-DRB1 * 0901 alleles might be correlated with BMT recipients happened higher pp65 antigenemia, HLA-A * 2402 alleles might be correlated with BMT recipients happened lower pp65 antigenemia.</p>
