Detection and of peripheral blood B cell activating factor in warm autoimmune hemolytic anemia patients and its implication / 中华血液学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To detect the B cell activating factor (BAFF) and explore its significance in patients with warm autoimmune hemolytic anemia (WAIHA).</p><p><b>METHODS</b>The levels of serum soluble BAFF (sBAFF) and BAFF mRNA in peripheral blood mononuclear cells (PBMCs) in 30 healthy volunteers (control group) and 43 patients with WAIHA were measured by ELISA and real-time quantitative polymerase chain reaction (RT-qPCR) respectively.</p><p><b>RESULTS</b>The levels of serum sBAFF and BAFF mRNA in PBMCs in pretreatment group \[2311 (825 approximately 6523) ng/L and 884 (463 approximately 2346) ng/L\] was significanly higher than those in posttreatment group\[1205(358 approximately 5014) ng/L and 446(138 approximately 2699) ng/L\] and control group\[1128 (590 approximately 3201) ng/L and 341 (102 approximately 965) ng/L\] (both P < 0.01), the difference between the posttreatment group and control group was not statistically significant. There was no significant difference between therapy responsive and nonresponsive groups before treatment. There was a significant difference between the pre- and post-treatment resuets in responsive group (P < 0.01), but not in nonresponsive group (P > 0.05). The serum levels of sBAFF was positively correlated with the levels of the BAFF mRNA in PBMCs both in pre- and post therapy group (both P < 0.05).</p><p><b>CONCLUSION</b>The levels of serum sBAFF and BAFF mRNA in PBMCs are increased in patients with WAIHA, their dynamic alterations may contribute to the development of WAIHA.</p>
