Markers of eosinophilic inflammation and risk prediction in patients with coronary artery disease.

BACKGROUND: The eotaxin family comprises three distinct peptides (eotaxin, eotaxin-2 and eotaxin-3) which have been implicated in eosinophilic inflammation. In vitro and clinical studies suggest that eotaxins could play a role in vascular inflammation, but no data are available on their prognostic significance in patients with angiographically documented coronary artery disease (CAD). MATERIALS AND METHODS: Baseline plasma samples were obtained from 1014 patients with documented CAD. We tested the predictive effect of markers of eosinophilic inflammation and C-reactive protein (CRP) on death from cardiovascular causes and nonfatal myocardial infarction over a 2.7-4.1-year follow-up period. RESULTS: Unexpectedly, lower eotaxin-3 concentrations were observed in patients with adverse cardiovascular events, whereas both eotaxin and eotaxin-2 showed no association with risk. After adjustment for most potential confounders, patients in the upper-quartile of eotaxin-3 levels had a 0.42 hazard-ratio (95% CI, 0.29-0.61, P < 0.001) for adverse events compared with subjects in the lower-quartile. The highest risk of future cardiovascular events was observed in subjects with combined elevation of CRP and reduction of eotaxin-3; 4.4 hazard-ratio (95% CI, 2.1-9.5, P < 0.001). Importantly, receiver-operating-characteristic curves analysis suggested a superior prognostic value of eotaxin-3 compared with CRP for predicting cardiac events in patients with CAD. CONCLUSIONS: Low levels of eotaxin-3 are an independent predictor of future adverse cardiovascular events in patients with CAD and may be useful for risk stratification.

Apo(a) size in ischemic stroke: relation with subtype and severity on hospital admission.

OBJECTIVE: To determine the distribution of apolipoprotein (a) (apo[a]) isoforms and their relation to the clinical severity of different ischemic stroke subtypes. METHODS: Ninety-four hospital cases with a first-ever ischemic stroke and 188 randomly selected control subjects matched for age, gender, and ethnicity were enrolled. Stroke etiology was defined according to Trial of Org 10172 in Acute Stroke Treatment criteria. NIH Stroke Scale (NIHSS) was used to assess the severity of stroke on admission. RESULTS: In univariate analysis, the presence of at least one small apo(a) isoform was associated with ischemic stroke in men (p = 0.02) but not in women (p = 0.33). After allowance for age, gender and traditional vascular risk factors, subjects carrying at least one small apo(a) isoform were at increased risk of atherothrombotic stroke (odds ratio [OR] 7.1, 95% CI 2.8 to 17.5, p = 0.00001) but not of lacunar infarction (OR 1.1, 95% CI 0.5 to 2.7, p = 0.78). Multivariate logistic regression analysis revealed that in the atherothrombotic stroke group, the presence of at least one small-sized apo(a) phenotype was associated with an NIHSS score > or =6 (OR 13.6, 95% CI 1.6 to 111.9, p = 0.015). CONCLUSION: Small apolipoprotein (a) isoforms distinguish atherothrombotic stroke from lacunar infarction and are associated with the severity of atherothrombotic stroke.

Apolipoprotein(a) size polymorphism is associated with coronary heart disease in polygenic hypercholesterolemia.

BACKGROUND AND AIM: In addition to high serum cholesterol levels, various cardiovascular risk factors may be involved in the development of coronary heart disease (CHD) in hypercholesterolemic subjects. As the levels of lipoprotein(a) [Lp(a)], an important and independent cardiovascular risk factor, are high in polygenic hypercholesterolemia (PH), we investigated plasma Lp(a) levels and apolipoprotein(a) [apo(a)] phenotypes in relation to occurrence of CHD events in PH patients. METHODS AND RESULTS: Lp(a) levels and apo(a) isoforms were determined in 191 PH patients, 83 normocholesterolemic subjects with CHD, and 94 normocholesterolemic controls without CHD. Lp(a) levels were similar in the hypercholesterolemic subjects with (n=100) or without CHD (n=91): 21.4 (range 6.6-59.23) vs 18.5 (range 5.25-57.25) mg/dL (p=NS). Low molecular weight apo(a) isoforms were more prevalent (55%) in the PH patients with CHD, whereas high molecular weight apo(a) isoforms were more prevalent (62.6%) in those without CHD: this difference was significant (p<0.05). A stepwise multiple-discriminant analysis made in order to determine the independence of common cardiovascular risk factors, Lp(a) levels and low molecular weight apo(a) isoforms in predicting CHD among hypercholesterolemic subjects showed that the presence of a positive family history of CHD, smoking, age, and the presence of at least one apo(a) isoform of low molecular weight were independently associated with CHD. CONCLUSIONS: Despite high Lp(a) levels, our findings do not support the hypothesis that Lp(a) plays an independent role in determining clinical CHD in PH subjects. However, the presence of at least one low molecular weight apo(a) isoform is an independent genetic predictor of CHD in hypercholesterolemic subjects. Together with other cardiovascular risk factors, apo(a) phenotypes should be assessed to evaluate the overall CHD risk status of all subjects with high serum cholesterol levels.

[Clinical comparison of different replacement milk formulas in children with allergies to cow's milk proteins. 24-month follow-up study].

The elective treatment for allergy to cow's milk protein is the elimination of these proteins from the diet. The present study with a follow-up of over two years took the form of a comparison between different replacement formulas based on soya (group A), hydrolysate of soya and bovine collagen (group B), and hydrolysate of casein (group C), randomly administered to 55 children (30 males and 25 females, aged between 2-48 months) with documented allergy to cow's milk proteins, but with different clinical symptoms. Tests to evaluate the acquisition of clinical tolerance to cow's milk proteins were performed using a day-hospital regime every 6 months. Sensitivity reactions were observed in 22% of cases in group A, 8% in group B and 37.5% in group C. It is worth underlining that 5 of the 6 children with reactions to soya protein then showed an excellent tolerance to hydrolysate of soya when it was administered subsequently until tolerance was achieved. Weight and statutory growth was uniformly good in all three groups. A high percentage of children achieved tolerance after 24 months (72%); the mean time taken to acquire clinical tolerance was 11.6 +/- 4.8 in group A, 11.6 +/- 6.02 in group B, and 14 +/- 5.6 in group C. No correlation was found between the type of initial symptoms, age at onset, method of response to first challenge and the time taken to acquire tolerance.

Erectile dysfunction and angiographic extent of coronary artery disease in type II diabetic patients.

Some studies observed an association between erectile dysfunction (ED) and coronary artery disease (CAD) extent in the general population, but others did not. There are no specific studies in diabetic populations. The aim of the present study was to evaluate whether ED is correlated with the extent of angiographic CAD in a large group of type II diabetic patients. We recruited 198 consecutive type II diabetic males undergoing an elective coronary angiography to evaluate chest pain or suspected CAD. Presence and degree of ED were assessed by the International Index Erectile Function - 5 (IIEF-5) questionnaire. ED was considered present, when IIEF-5 score was < or =21. Moreover, each domain of IIEF-5 was considered. Angiographic CAD extent was expressed both by the number of vessels diseased and by the Gensini scoring system. The percentage of subjects with ED was significantly higher (45.8 versus 15.8%; P=0.0120) in patients with (n=179) than in those without (n=19) significant angiographic CAD (stenosis of the lumen > or =50%). No significant association of CAD extent with presence of ED, total IIEF-5 score and each domain of IIEF-5 was observed. Our study shows that ED was significantly more prevalent in type II diabetic males with angiographic CAD than in those with normal arteries. However, no correlation was found between the extent of angiographic CAD and the presence or the severity of ED.
