Correlation of coagulation indicators with inflammatory markers for sepsis in the patients with hematological malignancies

Abstract

This study was aimed to investigate the correlation of coagulation indicators [prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and fibrinogen (FIB), antithrombinIII (ATIII), D-dimer (D-D) levels] with inflammatory markers [procalcitonin (PCT), C reactive protein (CRP), interleukin-6 (IL-6), serum amyloid A (SAA)] for sepsis in hematologic malignancy patients. A total of 326 febrile in patients with hematologic diseases from 2062 patients in West China Hospital, Sichuan University from March 2011 to April 2013 were retrospectively analyzed. The patients were divided into sepsis group(n = 72), non-sepsis group(n = 176) and non-sepsis with low Alb group (n = 78) according to blood culture. The results showed that the values of PT, APTT, D-dimer, Plt in sepsis group were higher than those in non-sepsis group, and the difference between them was statistically significant. While the ATIII level in the sepsis group was lower than that in non-sepsis group, and the difference between them was statistically significant (P < 0.05). And the four inflammatory biomarkers in the sepsis patients were higher than those in non-sepsis patients (P < 0.05). TT and FIB level were not significantly different (P > 0.05). There was not a significant difference in these indicators between non-sepsis group and non-sepsis with low Alb group. The correlation analysis suggested that the level of PCT positively correlated with APTT, D-dimer level (P < 0.05); and negatively correlated with the ATIII (P < 0.05). It is concluded that sepsis results in the concurrent activation of inflammatory and procoagulant pathways. The hematologic malignancy patients with sepsis have an obviously higher systemic inflammatory response, and accompanied with coagulation dysfunction.
