Relationship between serum ferritin level and outcomes in patients with acute spontaneous intracerebral hemorrhage / 国际脑血管病杂志

ABSTRACT

Objective To investigate the change regulation of the serum ferritin level and its correlation with the clinical outcomes.Methods The patients with spontaneous intracerebral hemorrhage were enrolled.Their clinical data were collected.The serum ferritin levels were detected within 24 h after admission and on day 3,7,and 14,respectively.The modified Rankin Scale (mRS) were used to evaluate the clinical outcomes at day 90 after onset.mRS 0 to 2 was defined as good outcome and ＞ 2 was defined as poor outcome.Results A total of 32 patients with spontaneous intracerebral hemorrhage were enrolled,including 18 in the good outcome group and 14 in the poor outcome group.There were significant differences in age (66.33 ±12.57 years vs.76.50 ±6.55 years;t =-2.908,P =0.007),baseline National Institutes of Health Stroke Scale (NIHSS) scores (median [interquartile range];9.50 [4.75-11.25] vs.15.00 [11-20];Z=-3.499;P=0.001),diastolic blood pressure (82.16± 13.79 mmHg vs.94.76± 12.17mmHg,1 mmHg=0.133 kPa);t=-1.145,P=0.045),amount of bleeding (4.50 [2.75-9.00] mlvs.11.00 [7.50-15.00] ml;Z=-2.613,P=0.008],blood glucose (5.82±0.87 mmoFL vs.7.09±1.72 mmoFL;t =-2.548,P =0.020),and white blood cell count ([7.26 ± 2.36] × 109/L vs.[10.94 ±5.83] × 109/L;t =-2.440,P =0.021) between the good outcome group and the poor outcome group.The serum ferritin levels of the good outcome group were 139.81 ± 98.50 μg/L,181.77 ± 97.29 μg/L,198.17 ±96.63 μg/L,and 159.59 ±72.43 μg/L,respectively,within 24 h on admission and at day 3,7,and 14.There were no significant differences at each time point (F=1.397,P =0.251),and those of the poor outcome group were 226.07 ± 119.22 μg/L,297.36 ± 81.48 μg/L,305.45 ± 97.05 μg/L,and 307.74 ± 82.54 μg/L,respectively,and they increased progressively over time (F =4.245,P =0.044);at each time point,the good outcome group was significantly lower than the poor outcome group (within 24 hon admissiont =-2.242,P=0.033;at 3 days after onsett =-3.234,P =0.003;at 7 days after onsett =-3.149,P =0.004;at 14 days after onsett =-3.628,P =0.001).Multivariate logistic regression analysis showed that the serum ferritin level within 24 h on admission (odds ratio 1.048,95％ confilence interval 1.004-1.095;P=0.034)and baseline NIHSS score (odds ratio 1.021,95％ confidence interval 1.004-1.039;P =0.016) were the independent risk factors for affecting the outcomes in patients with acute intracerebral hemorrhage.Conclusions The serum ferritin level increases in the poor-outcome patients with acute intracerebral hemorrhage.The increased serum ferritin level is an independent risk factor for poor outcome in patients with acute intracerebral hemorrhage.
