title: [A case of hemophagocytic lymphohistiocytosis syndrome caused by severe tuberculosis and literature review].
abstract: OBJECTIVE
  To investigate the clinical features of a case of hemophagocytic lymphohistiocytosis syndrome (abbreviated as hemophagocytic syndrome, HPS) caused by severe tuberculosis and therefore to improve early diagnosis of this condition.
  
  
  METHODS
  The clinical features and process of diagnosis and treatment of a case with HPS caused by severe tuberculosis in July 2011 were analyzed, and the reported literatures of the disease were reviewed.
  
  
  RESULTS
  The patient was a 16-year-old male. The primary manifestations were fever, cough, abdominal distention and edema. Laboratory analysis indicated pancytopenia (WBC 3.0×10(9)/L, Hb 98 g/L, PLT 34×10(9)/L), liver dysfunction (ALT 51.5 U/L, AST 211 U/L, TBIL 20 µmol/L, DBIL 17.6 µmol/L), coagulation abnormalities (extension of TT and APTT, FIB 0.56 g/L), high level of ferritin (662 µg/L), and hemophagocytosis in bone marrow. Sputum smear was positive for tubercule bacillus. After 2 months of antituberculous therapy with ethambutol, streptomycin and sodium aminosalicylate, along with administration of prednisolone, human immunoglobulin, and thymic peptide α(1), the patient's body temperature, function of coagulation and liver abnormalities all returned to normal, and repeated sputum smears became negative.
  
  
  CONCLUSIONS
  Tuberculosis is a cause of reactive hemophagocytic syndrome. Patients with hemophagocytic symptom should be rigorously screened for tuberculosis, and antituberculous therapy should be initiated early to improve prognosis.
