Long-term Follow-up of Patients with Hepatitis-Associated Aplastic Anemia / 中国实验血液学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the clinical characteristic, therapeutic efficacy and prognosis of patients with hepatitis-associated aplasitc anemia (HAAA).</p><p><b>METHODS</b>the clinical data and labrotatory examination results of 30 cases of HAAA were analyzed retrospectively, the 6-month response ratio and overall survival (OS) were assessed.</p><p><b>RESULTS</b>HAAA most commonly occured in males, with the occurence rate of males and females was 41, the median onset age was 16 (4-43) years old, HAAA oriented focus on sever aplastic anemia (SAA)(4 cases,13%) and very sever aplastic anemia (VSAA)(22 cases,73%). Aplastic anemia (AA) could be seen on occurence of hepatitis (accompanied aplastic anemia) (7 cases,23%), or after the onset of hepatits (delayed aplastic anemia) (23 cases,77%), but more often occured in the latter. Statistical analysis showed that when compared with the patients of delayed aplastic anemia, patients accompanied aplastic anemia possesses lower levels of glutamic-pyruvic transaminase(ALT), aspertate aminotransferase (AST) and total bilirubin (TBIL)(P=0.042,0.012,0.001), and possessed a more obvious lymphoid cell disorder when AA occured, with more lower peripheral blood CD19B cells proportion (P=0.046) and more obvious imbalance of CD4/CD8ratio, but the difference was no statistical significant (P=0538). Factors affecting the 6-month respose were the severity of AA (P=0.044), the peak level of bilirubin of hepatitis (P=0.006) and the propotion of mature monocyte in bone marrow (P=0.034). The long-term follow-up showed that the 2-year OS of HAAA was 64.3±9.2%, the 6-month curative efficacy significantly affect the prognosis (P<0.001).</p><p><b>CONCLUSION</b>HAAA more often occur in young male, HAAA is mainly SAA and VSAA and mostly non-A-C hepatitis associated aplastic anemia, patients usually have a high incidence of early infection. Patients acompanied with aplastic anemia possess more obvious immunological derangement; the treatment efficacy for HAAA is poor, patients who haven't obtained 6-month response indicate a sinister prognosis, allogeneic hematopoietic stem cell transplantion is a better choice for these patients.</p>
