Nutritional status in acute stage ischemic stroke and its relation to disease severity and prognosis of patients / 浙江大学学报·医学版

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the nutritional status in acute stage ischemic stroke and its relation to disease severity and prognosis of patients.</p><p><b>METHODS</b>Fifty patients with ischemic stroke were admitted in hospital within 48 h after onset. National Institute of Health stroke scale (NIHSS) was used to assess the severity of stroke. Physical index and laboratory index were measured on d1, d7 and d14 after admission. Physical index included body weight, body mass index, triceps skin folds, upper arm circumference and arm muscle circumference. Laboratory index included prealbumin, high sensitivity C-reactive protein (hs-CRP), complement C3 and cortisol. The severity of metabolic disturbance was expressed as the difference of biochemical indexes between the d7 and d1. All cases were followed up for 6 months. The prognosis of stroke was evaluated with modified Rankin (mRankin) scores.</p><p><b>RESULTS</b>No significant changes of physical indexes were found between d7 and d1. The levels of prealbumin and complement C3 on d7 after admission were significantly decreased compared to d1 (198.8 mg/L±20.3 mg/L vs 286.7 mg/L±23.8 mg/L and 0.6 g/L±0.1 g/L vs 1.0 g/L±0.1 g/L, respectively, both P<0.05). The levels of hs-CRP and cortisol at d7 were significantly increased compared to d1 (495.2 nmol/L±39.5 nmol/L vs 24.1 mg/L±5.2 mg/L and 396.4 nmol/L±41.3 nmol/L vs 5.1 mg/L±1.2 mg/L, respectively, both P<0.05). On d14 after admission hs-CRP (13.2 mg/L±4.5 mg/L) and cortisol levels (463.4 nmol/L±32.1 nmol/L) were still significantly higher than d1 (both P<0.05). However, there were no difference in prealbumin (259.2 mg/L±22.8 mg/L) and complement C3 (0.8 g/L±0.2 g/L) levels between d1 and d14 after admission. Correlation analysis revealed that the NIHSS scores and mRankin scores were correlated with nutrition metabolism disturbances (P<0.05).</p><p><b>CONCLUSION</b>Nutrition metabolism disturbances in patients with acute ischemic stroke are related to the disease duration, the severity and prognosis of stroke.</p>
