Expressions of plasma cystatin C, D-dimer and hypersensitive C-reactive protein in patients with intracranial progressive hemorrhagic injury after craniocerebral injury, and their clinical significance.

OBJECTIVE: To investigate the expressions of plasma cystatin C (Cys-C), D-dimer (D-D) and hypersensitive C-reactive protein (hs-CRP) in patients with intracranial progressive hemorrhagic injury (IPHI) after craniocerebral injury, and their clinical significance. METHODS: Forty-two IPHI patients and 20 healthy participants (control) were enrolled. The severity and outcome of IPHI were determined according to the Glasgow Coma Scale and Glasgow Outcome Scale, and the plasma Cys-C, hs-CRP and D-D levels were measured. RESULTS: The plasma Cys-C, D-D and hs-CRP levels in the IPHI group were significantly higher than those in the control group (p < 0.01). There were significant differences of plasma Cys-C, D-D and hs-CRP levels among different IPHI patients according to the Glasgow Coma Scale and according to the Glasgow Outcome Scale (all p < 0.05). In the IPHI patients, the plasma Cys-C, D-D and hs-CRP levels were positively correlated with each other (p < 0.001). CONCLUSION: The increase of plasma Cys-C, D-D and hs-CRP levels may be involved in IPHI after craniocerebral injury. The early detection of these indexes may help to understand the severity and outcome of IPHI.

RESUMO Objetivo Investigar as expressões da cistatina C plasmática (Cys-C), dímero-D (D-D) e proteína C-reativa hipersensível (hs-CRP) em pacientes com lesão hemorrágica progressiva intracraniana (IPHI) após lesão craniocerebral e seus significados clínicos. Métodos Quarenta e dois pacientes com IPHI e 20 indivíduos saudáveis (controle) foram incluídos. A gravidade e o resultado do IPHI foram determinados de acordo com a Escala de Coma de Glasgow (GCS) e Escala de Resultados de Glasgow (GOS), e os níveis plasmáticos Cys-C, hs-CRP e D-D foram detectados. Resultados Os níveis plasmáticos de Cys-C, D-D e hs-CRP no grupo IPHI foram significativamente maiores do que no grupo controle (P <0,01). Houve diferença significativa entre os níveis plasmáticos de Cys-C, D-D e hs-CRP entre os diferentes pacientes com IPHI de acordo com a GCS e entre os diferentes pacientes com IPHI de acordo com o GOS, respectivamente (todos P <0,05). Em pacientes com IPHI, os níveis plasmáticos de Cys-C, D-D e hs-CRP foram positivamente correlacionados entre si (P <0,001). Conclusão O aumento dos níveis plasmáticos de Cys-C, D-D e hs-CRP pode estar envolvido no IPHI após trauma crânio-encefálico. A detecção precoce desses índices pode ajudar a entender a gravidade e o resultado do IPHI.
