Abstract

ObjectiveTo investigate the effects of rabbit anti-human thymocyte globulin (R-ATG) and Jurkat cell-reactive anti-T lymphocyte globulin (ATG-F) in the treatment of childhood aplastic anemia (AA) and compare their efficacy and side effects. Patients and MethodsA total of 53 children with AA were analyzed in the present study, including 32 cases of severe AA (SAA), 10 cases of very severe AA (VSAA) and 11 cases of transfusion-dependent non-severe AA (NSAA). While receiving immunosuppressive therapy (IST), 29 and 24 patients, with long-term oral supplement with cyclosporin A (CSA), androgen and traditional Chinese medicines, were treated with R-ATG and ATG-F, respectively. If necessary, the patients were also given supportive cares such as component transfusion and/or infection control. Absolute counts of peripheral blood lymphocyte (ALC) in various time points were dynamically measured after ATG therapy. ResultsAccording to the International AA Treatment and Effect standards, we found that there were no statistically significant differences in the response rate (70.83% vs.68.97%, P>0.05) and the overall survive rate (83.33% vs.82.76%, P>0.05) between the ATG-F and R-ATG groups. In addition, no obvious differences were observed between these two groups in the response time, efficacy of SAA and VSAA, or the incidence rates of ATG-related adverse reactions. After ATG treatment, the extent of ALC reduction and duration in peripheral blood were similar between the ATG-F and R-ATG groups. ConclusionThe results of this study showed that ATG-F and R-ATG, had similar efficacy and adverse reactions in the first-line treatment of childhood AA, despite they are derived from different immunogens. .
