Abstract

Objective. To determine the prognostic significance of beta2 microglobulin β2-m concentrations in patients with hemophagocytic lymphohistiocytosis HLH, a rare disorder caused by pathologic activation of the immune system. Patients and Methods. The study population consisted of 74 patients diagnosed with HLH and 35 healthy controls. Serum β2-m levels were measured using a latex agglutination photometric immunoassay. Results. Median serum β2-m levels were significantly higher in HLH patients than in healthy controls 4.05 versus 1.5 mg-L; and were significantly higher in patients with lymphoma associated hemophagocytic syndrome LAHS than in patients with benign disease-associated HLH 4.2 versus 3.3 mg-L; . Higher serum β2-m levels were positively correlated with LAHS , abnormal lactate dehydrogenase concentrations , and hypoalbuminemia . ROC analysis showed that overall survival OS was significantly shorter in LAHS patients with serum β2-m levels ≥4.03 mg-L compared to <4.03 mg-L . Moreover, multivariate analysis showed that serum β2-m level was an independent prognostic of OS in patients with LAHS. Conclusion. High serum β2-m levels and LAHS were associated with markedly poorer OS in patients with HLH. Serum β2-m concentration was a powerful and independent prognostic factor for OS in patients with LAHS.
