[show abstract] [hide abstract]
ABSTRACT: BACKGROUND: Inflammation plays a crucial role in the pathogenesis and prognosis of stroke. We studied the behavior of lipoprotein(a) [Lp(a)], ferritin, and albumin as acute phase reactants and their roles in the severity and mortality of stroke. METHODS: We recruited 100 consecutive patients with acute ischemic stroke and 120 controls. Blood samples were drawn on days 1 and 7 and at both 3 and 6 months. Stroke was classified using Trial of Org 10172 in Acute Stroke Treatment classification. Stroke severity was assessed using the National Institutes of Health Stroke Scale. Prognosis at 6 months was assessed using the modified Rankin Scale, and mortality was assessed using the Kaplan-Meier analysis. Serum levels of interleukin-6 (IL-6), Lp(a), ferritin, and albumin were measured using enzyme-linked immunosorbent assay, immunoturbidimetry, and chemiluminescence commercial kits, respectively. RESULTS: Levels of IL-6, Lp(a), and ferritin were consistently higher among cases than controls (P < .0001). Serum Lp(a) levels peaked at day 7 after stroke and tapered thereafter. Albumin levels were lower than controls on admission day and increased subsequently. In our study, Lp(a) acted as an acute phase reactant while albumin acted as a negative acute phase reactant. There was no association between Trial of Org 10172 in Acute Stroke Treatment subtype and elevated serum levels of Lp(a), albumin, and ferritin. Lp(a) and ferritin were high in patients with severe stroke. Albumin was negatively correlated with stroke severity. Serum levels of Lp(a) ≥77 mg/dL, albumin ≤3.5 g/dL, and ferritin ≥370 ng/dL is associated with a significantly increased risk of having a poorer outcome in stroke. Serum levels of Lp(a) >77 mg/dL and albumin <3.5 g/dL were also associated with increased mortality. CONCLUSIONS: High levels of Lp(a) and ferritin and low levels of albumin are associated with increased severity and poorer long term prognosis of stroke. Patients with admission levels of Lp(a) >77 mg/dL and albumin <3.5 g/dL had increased mortality.Journal of stroke and cerebrovascular diseases: the official journal of National Stroke Association 12/2012; -
Article: Interleukin-6 Gene -174 G/C Promoter Polymorphism Predicts Severity and Outcome in Acute Ischemic Stroke Patients from North India.

ABSTRACT: BACKGROUND: A guanine/cytosine (G/C) substitution occurring in position -174 of the interleukin-6 (IL-6) gene promoter changes the expression of IL-6 circulating proteins. We evaluated the occurrence of IL-6 -174 G/C polymorphism in patients with acute ischemic stroke and studied its association with stroke severity, outcome, and mortality. METHODS: One hundred patients with acute ischemic stroke and 120 age and sex-matched healthy controls were studied. Genotyping was performed using polymerase chain reaction and restriction enzyme analysis. Serum levels of IL-6 were measured using enzyme-linked immunosorbent assay. Stroke was classified using Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification. Severity was assessed by the National Institutes of Health Stroke Scale. Outcome measures included modified Rankin Scale (mRS) and Barthel Index (BI) scores at 7 days and 3 and 6 months. Mortality/survival was assessed using the Kaplan-Meier analysis. RESULTS: The frequency of GG, GC, and CC genotypes did not differ significantly between cases and controls. No association was seen between TOAST subtype and genotype. At the time of admission, stroke was more severe in patients with the GC genotype (P = .03) and less severe in the GG genotype (P = .04). The GC genotype was also associated with higher serum IL-6 levels and poor short-term (BI P = .001; mRS P = .003) and long-term outcomes (BI P = 9 × 10(-5); mRS P = 9 × 10(-5)), while the GG genotype had significantly lower serum IL-6 levels and better short and long-term outcomes (BI P = 3 × 10(-5); mRS P = 2 × 10(-4)). There was significantly lesser mortality in the GG genotype and more in the GC genotype based on the Kaplan-Meier analysis. CONCLUSIONS: Patients with the GC genotype had more severe strokes with poorer short and long-term outcomes and increased mortality. The GG genotype was associated with less severe strokes, better short and long-term prognosis, and survival. The GG genotype appears to be protective against stroke severity, outcome, and mortality.Journal of stroke and cerebrovascular diseases: the official journal of National Stroke Association 03/2012; -
Article: Comparison of the various lipid ratios and indices for risk assessment in patients of myocardial infarction.
[show abstract] [hide abstract]
ABSTRACT: Coronary artery disease (CAD) has emerged as the major cause of morbidity and mortality among Asian Indians in the recent past. The following study was undertaken to assess the predictive value of novel biomarkers of dyslipidemia for risk assessment for CAD in the Indian population. The study group comprised of 100 clinically assessed patients of myocardial infarction and 100 age and sex matched healthy controls. Apolipoprotein-A (Apo-AI) and Apolipoprotein-B (Apo-B) were estimated and small dense LDL was derived mathematically. The cases showed significantly high levels of total serum cholesterol, triglycerides, LDL cholesterol, Apo-B, sdLDL, and non-HDL cholesterol. On carrying out multivariate regression analysis, Lp(a)/HDL ratio emerged as the best determinant of CAD risk The above data clearly underlines the role of these novel biomarkers in the risk assessment for CAD in the Indian context.Clinical biochemistry 01/2012; 45(6):445-9. · 2.02 Impact Factor
