ABSTRACT

BACKGROUND: The objective of our study was to determine the serum concentrations of protein S100B and neuron specific enolase (NSE) as well as their ability and accuracy in the prediction of early neurological outcome after a traumatic brain injury. METHODS: A total of 130 polytraumatized patients with the associated traumatic brain injuries were included in this prospective cohort study. Serum protein S100B and NSE levels were measured at 6, 24, 48 and 72 hours after the injury. Early neurological outcome was scored by Glasgow Outcome Scale (GOS) on day 14 after the brain injury. RESULTS: The protein S100B concentrations were maximal at 6 hours after the injury, which was followed by an abrupt fall, and subsequently slower release in the following two days with continual and significantly increased values (p<0.0001) in patients with poor outcome. Secondary increase in protein S100B at 72 hours was recorded in patients with lethal outcome (GOS 1). Dynamics of NSE changes was characterized by a secondary increase in concentrations at 72 hours after the injury in patients with poor outcome. CONCLUSION: Both markers have good predictive ability for poor neurological outcome, although NSE provides better discriminative potential at 72 hours after the brain injury, while protein S100B has better discriminative potential for mortality prediction.

ABSTRACT

AIM: To assess IL-10 serum concentration according to outcome of severe trauma treatment and influence of short nuclear polymorphism (SNP) 1082G/A within IL-10 gene on treatment outcome of patients with severe trauma. METHODS: Forty-seven patients with major trauma were prospectively recruited, and they were divided into two groups according to outcome (survivors and non-survivors). The IL-10 gene polymorphisms were genotyped using restriction fragment length polymorphism analysis. Serum IL-10 levels were determined with enzyme-linked immunosorbent assay. Association between IL-10 serum concentration, IL-10 SNP type and IL-10 serum concentration in groups of patients with different SNPs with outcome after severe trauma was evaluated. RESULTS: Mean age of patients was 35.53±14.53 years. The major mechanism of injury was traffic, and the mean injury severity score was 35.47±11.23. Despite higher values of IL-10 serum concentrations in patients with lethal outcome, the difference was not statistically significant. In 40 (85%) patients no gene polymorphism for IL-10 was recorded. No statistical significance in frequency of IL-10-1082 gene polymorphism was observed between the patients with different outcomes of polytrauma. No statistically significant difference in IL-10 values was evidenced between the subjects with and without polymorphisms in any of the observed times of measurement, although a trend toward the higher values may be observed in patients with polymorphism in heterozygous form. CONCLUSION: The patients with IL-10 SNP gene polymorphism despite no proven statistical significance appeared to have higher values of IL-10 and consequently worse outcome.

ABSTRACT

In polytrauma, injuries that may be surgically treated under regular circumstances due to a systemic inflammatory response become life-threatening. The inflammatory response involves a complex pattern of humoral and cellular responses and the expression of related factors is thought to be governed by genetic variations. This aim of this paper is to examine the influence of interleukin (IL) 6 single nucleotide polymorphism (SNP) -174C/G and -596G/A on the treatment outcome in severely injured patients. Forty-seven severely injured patients were included in this study. Patients were assigned an Injury Severity Score. Blood samples were drawn within 24 h after admission (designated day 1) and on subsequent days (24, 48, 72 hours and 7 days) of hospitalization. The IL-6 levels were determined through ELISA technique. Polymorphisms were analyzed by a method of Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR). Among subjects with different outcomes, no statistically relevant difference was found with regards to the gene IL-6 SNP-174G/C polymorphism. More than a half of subjects who died had the SNP-174G/C polymorphism, while this polymorphism was represented in a slightly lower number in survivors. The incidence of subjects without polymorphism and those with heterozygous and homozygous gene IL-6 SNP-596G/A polymorphism did not present statistically significant variations between survivors and those who died. The levels of IL-6 over the observation period did not present any statistically relevant difference among subjects without the IL-6 SNP-174 or IL- 6 SNP -596 gene polymorphism and those who had either a heterozygous or a homozygous polymorphism.
