[Clinical analysis on 28 patients with hemophagocytic lymphohistiocytosis syndrome].
In order to profoundly understand the clinical and laboratorial characteristics and inducing factors of hemophagocytic lymphohistiocytosis syndrome (HLH), 28 HLH patients received from 2004 to 2009 years in our hospital were analyzed retrospectively. The results indicated that all of the patients had a history with prolonged fever (more than 1 week), pancytopenia, hepatosplenomegaly, elevated ferritin level, hypofibrinogen, and hemophagocytosis in bone marrow. HLH was the first characteristic sign of malignant lymphoma in 9 patients; 1 patient had a clinical manifestation similar to fulminant hepatic failure; severe psycho-abnormality occurred in 1 HLH patient and pronounced hemophagocytosis were detected in his cerebrospinal fluid; 1 patient was eventually diagnosed as having HLH by the findings in a lymph node biopsy showing obvious hemophagocytosis. Additionally, the analysis of underlying factors in 28 patients with HLH indicated 11 patients with EB virus-associated HLH, 11 with lymphoma-associated HLH, 2 with Leishmania-associated HLH, and 3 with autoimmune disease-associated HLH. It is concluded that HLH disease is characterised with high heterogenicity in both clinical features and inducing factors; in addition, the patients from a pasturing area should be paid attention to parasite infection such as leishmania.
