Stroke is the third major cause of death and foremost cause of disability worldwide. Cerebrovascular stroke remains largely a clinical diagnosis. The use of biomarkers in diagnosing stroke and assessing prognosis is an emerging and rapidly evolving field. The study aimed to investigate the predictive value of neurobiochemical marker of brain damage (neuron-specific enolase [NSE]) with respect to degree of disability at the time of admission and neurological worsening in acute ischemic stroke patients. We investigated 150 patients with cerebrovascular stroke who were admitted within 72 h of onset of stroke in the Department of Neurology at SAIMS. Venous blood samples were taken after admission and NSE was analyzed by solid enzyme linked immunosorbent assay using Analyzer and microplate reader from Biored: Code 680. In all patients, the neurological status was evaluated by a standardized neurological examination and the National Institutes of Health Stroke Scale on admission and on day 7. Serum NSE concentration was found to significantly correlate with both degree of disability and neurological worsening in acute ischemic stroke cases in the present study. The maximum serum NSE level within 72 h of admission was significantly higher in patients with greater degree of disability at the time of admission. Serum NSE levels were also found to be significantly elevated in patients with bad neurological outcome. Our study showed that serum NSE has high predictive value for determining severity and early neurobehavioral outcome after acute stroke.

Background:This study was undertaken to evaluate and establish the role of total sialic acid (TSA) and highly sensitive C-reactive protein (hs-CRP) in type 2 diabetes mellitus (T2DM) and its correlation with complications such as diabetic nephropathy.Materials and Methods:One hundred fifty-seven patients with T2DM with nephropathy (DN) and 162 patients of T2DM without nephropathy (DM) along with 165 unrelated age and sex-matched healthy controls were included in the study. Serum glucose (fasting and postprandial) levels, renal profile, and lipid profile were done as per standard protocol. Serum TSA test levels and hs-CRP level were evaluated using thiobarbituric acid assay and immunoturbidimetric method respectively.Results:We observed a higher concentration of serum TSA (82.67 ± 6.63 mg/dl) and hs-CRP (3.2 ± 1.44 mg/L) in diabetic nephropathy than the diabetes mellitus group (73.83 ± 6.90 mg/dl and 2.07 ± 1.32 mg/L, respectively). Both TSA and hs-CRP levels were found significantly correlated with fasting and postprandial blood sugar, hemoglobin A1c, and urine microalbumin levels in both DM and DN groups. Multinomial logistic regression analysis showed that both TSA and hs-CRP was independently associated with diabetic nephropathy.Conclusion:High serum TSA and hs-CRP levels may increase the microangiopathic (diabetic nephropathy) complications of T2DM.

Stroke is the third major cause of death worldwide. Elevated plasma concentration of low density lipoproteins and low plasma concentration of high density lipoprotein concentration are associated with an increased risk of atherosclerosis and coronary heart disease but the relation between serum lipids, and cerebrovascular disease is less clear. The aim of this study was to investigate the reliability and accuracy of serum lipid profile in assessing the prognosis/neurological worsening in patients with ischemic and hemorrhagic cerebrovascular stroke. The subjects in the present study comprised of 101 healthy controls and 150 cerebrovascular stroke patients (including 90 with ischemic stroke and 60 with intracerebral hemorrhagic stroke). In both the groups fasting lipid profile was determined within 72 h of the stroke. A statistically significant association was observed (p \ 0.001) between the parameters of lipid profile of cases and healthy controls, and also with the prognosis of the stroke.

Background:A study to investigate the level of the neurobiochemical marker, Neuron-Specific Enolase (NSE), at the time of admission and its correlation with the blood sugar level in ischemic stroke patients.Patients and Methods:We investigated 90 patients with complete stroke who were admitted to the Stroke Unit of the Department of Neurology at Sri Aurobindo Institute of Medical Sciences. NSE was measured with commercially available quantitative ‘sandwich’ enzyme-linked immunosorbent assay kits obtained from R and D Systems. Hyperglycemia was defined as blood glucose concentration ≥ 7 mmol / L, and measured using the glucose oxidase method immediately.Results:Significantly increased NSE and lipid profile levels were found in ischemic stroke patients as compared to the control. Hyperglycemic ischemic stroke patients had increased levels of NSE, lipid profile, and National Institute of Health stroke scale scores (NIHSS score) compared to normoglycemic ischemic stroke patients. In addition the serum NSE level of hyperglycemic stroke patients was also positively correlated with the blood sugar level (r = 0.734 P < 0.001).Conclusions:Hyperglycemia predicts an increased risk of poor outcome after ischemic stroke and it is reflected by a significantly increased level of Neuron-Specific Enolase.

Stroke being the third leading cause of death and foremost cause of disability, if potential diagnostic utility of blood borne protein biomarkers in predicting acute stroke is established, it would be a substantial adjunct to computerized tomography and magnetic resonance imaging which have their own limitations. This study was done to correlate serum Interleukin 6, high sensitivity C reactive protein at the time of admission with neurological worsening assessed by NIHSS at the time of admission and 7 days after admission. 46 Patients admitted in neurology department SAIMS, Indore with first ever ischemic stroke within 72 h of onset were included in the study. All patients with history of stroke of more than 72 h onset, Infection & peripartum stroke were excluded from the study. Disability scoring was done by NIHSS and their serum samples assayed for hsCRP, IL6 by commercially available quantitative sandwich enzyme-linked immunoadsorbent assay kits. Serum samples of 50 control cases which included healthy volunteers and staff from SAIMS were also analyzed for hsCRP, IL6 for comparative study.A significant correlation was observed between NIHSS scoring and serum hsCRP and IL6 at the time of admission. Patients with initial high serum IL6 and hsCRP also showed significant clinical deterioration as assessed by NIHSS scoring 7 days after admission. Elevated hsCRP and IL6 within 72 h of admission strongly correlated with functional disability in study population in India and may serve as useful adjunct to CT Scan in emergency setting.
