Özet

Because of the acute and life-threatening course of the hemophagocytic lymphohistiocytosis (HLH) syndrome, International Histiocyte Society guidelines recommend chemoimmune therapy for the treatment of both primary and secondary HLH (sHLH). To manage children with sHLH, instead of HLH-2004 protocol we considered less immunosuppressive/cytotoxic approach. We assessed 12 children who fulfilled the diagnostic criteria for sHLH between January 2009 and March 2015. Multivariate Cox regression analysis showed that ferritin levels (hazard ratio= 1.02, P = 0.006), pediatric logistic organ dysfunction scores (hazard ratio = 1.01, P = 0.001) were the predictors of the survival. The hospital survival was 83% for patients with sHLH who were treated with less immunosuppressive therapy. In conclusion initiation of HLH-specific therapy for the patients with hyperferritinemia-associated sHLH should be delayed while awaiting resolution of systemic inflammation with less immunosuppressive therapy.
