Myocardial infarction and alcohol consumption: a population-based case-control study.

BACKGROUND AND AIM: Coronary heart disease (CHD) is the leading cause of death in industrialized societies. Identifying and characterizing modifiable variables associated with CHD is an important issue for health policy. The aim of the present study was to analyze the association of non-fatal myocardial infarction with total alcohol consumption and type of alcoholic beverage consumed. Preference of the subjects' consumption for beer, wine, or spirits was set at 80% or more of total alcoholic beverage consumption. METHODS AND RESULTS: A population-based case-control study (244 subjects and 1270 controls) was conducted. Male patients aged 25 to 74 years with first myocardial infarction (MI) were recruited in the same region as the healthy male controls, who were taken from a random sample representative of the Gerona population. Alcoholic beverage consumption during the preceding week was recorded. Multiple logistic regression analysis was performed to determine the association of alcohol consumption and non-fatal MI. Total alcohol consumption up to 30 g per day, adjusted for lifestyle and cardiovascular risk factors, was inversely associated (Odds ratio 0.14; 95% confidence interval 0.06-0.36) with the risk of non-fatal MI. Drinking up to 20 g of alcohol through wine, beer and spirits significantly decreased the adjusted risk of MI. Higher alcohol intake did not substantially reduce the risk. A preference for spirits was correlated with a significantly increased risk of non-fatal MI (P<0.05). CONCLUSION: Moderate alcohol consumption, independent of the type of alcoholic beverage, was associated with non-fatal MI risk reduction.

Long-term safety and efficacy of nevirapine-based approaches in HIV type 1-infected patients.

Using a multicenter, cross-sectional, observation study, the long-term safety, metabolic profile, and viral efficacy of nevirapine (NVP)-based approaches in HIV-1-infected patients treated for at least 2 years were assessed. For 4 months, all consecutive HIV-1-infected patients who had been receiving an NVP-containing regimen for at least 2 years were recruited. A total of 613 patients were included with a median follow-up period of 43 months (IQR: 31-51). At baseline, 24.5% (150 patients) were treatment naive, 41.5% (254 patients) switched for simplification purposes, and 34% (209 patients) were failing HAART. Increases by five times or more in AST/ALT values were observed in fewer than 2% of patients. Only 5.7% of all adverse events reported during the investigation were attributable to NVP. The percentage of patients with normal HDL cholesterol levels rose from 17.7% at baseline to 35.4% at the last visit. At the latest time point available for analysis, 76% of naive and 74% of those who had switched had HIV-1 RNA loads of <50 copies/ml, while 59% of salvage patients achieved this level of viral suppression. Factors associated with viral suppression at the latest visit were adequate adherence (OR: 2.58, 95% CI: 0.85-7.78, p < 0.001), first-line treatment (OR: 3.02, 95% CI: 1.52-6.00, p = 0.002), and baseline CD4 cells >400 cells/microl (OR: 2.34, 95% CI: 1.22-4.47, p = 0.010). Exposure to nevirapine for up to 4 years is safe. Liver toxicity is infrequent and generally mild. HDL cholesterol levels consistently increase over time and viral suppression is maintained.

[Clinical-epidemiological characteristics and antiretroviral treatment trends in a cohort of HIV infected patients. The PISCIS Project].

BACKGROUND AND OBJECTIVE: The aims of this study were to describe the process of implementation of the PISCIS cohort, and to describe the clinical and epidemiological characteristics and trends of antiretroviral treatment (ART) among patients enrolled from 1998 through 2003. PATIENTS AND METHOD: Prospective cohort study of HIV-infected patients aged > or = 16 years newly attended in 10 Catalonian hospitals and one Balearic Islands hospital. Analysis were done using the Mantel's chi2 test for trend. RESULTS: A total of 5,968 patients (mean age 39 yrs; 75% men) were recruited with a mean follow-up of 26.4 months (13,130 person-years). A total of 2,763 patients were newly diagnosed and among these, the most frequent transmission route was the heterosexual one (43%), followed by homosexual (31%). We observed an increasing trend in the proportion of persons < 35 years and immigrants. Among newly diagnosed, 43% had < 200 CD4 T cells/microl in the nearest determination from HIV diagnosis. In the year 2003, 83% of patients were on ART. A decrease of the protease inhibitor-based regimen (from 85% in 1998 to 25% in 2003; p < 0.001) and an increase of nucleoside and non-nucleoside analogue reverse transcriptase inhibitors-containing regimens were observed over time among naive patients who started ART with three or more drugs. CONCLUSIONS: HIV infected patients' cohorts are feasible in our setting and are an important tool in clinical and public health. The heterosexual route of transmission was the most frequent among newly diagnosed patients. The diagnosis delay is high and, on the other hand, ARV regimens have been changing according to the recommended guidelines.
