Cholesterol control in stroke prevention in Italy: a cross-sectional study in family practice.

BACKGROUND: Stroke represents worldwide the second and seventh cause of death and invalidity, respectively. Patients with ischaemic stroke or transitory ischaemic attack (TIA) are at high risk of recurrence, therefore requiring intensive treatment. Hypercholesterolaemia is a modifiable risk factor for stroke. The general practitioners attitude towards detection and treatment of dyslipidaemia among patients with stroke or TIA in Italy is unknown; we therefore aimed to address this issue taking advantage of the database of The Italian College of General Practitioners. METHODS: Prevalence of the monitored factors (lipid levels, statin prescription, and lipid level control with hypolipidaemic agents prescription) were analysed on a patient population of 465 061. RESULTS: A total of 2555 (49% women and 51% men) patients with a diagnosis of stroke and 2755 patients (52% women and 48% men) with a diagnosis of TIA were included in the study. Total plasma cholesterol (TC) was reported in more than 60% of the patients and low-density lipoprotein cholesterol (LDLc) and high-density lipoprotein cholesterol (HDLc) in less than half. Total plasma cholesterol and LDLc were controlled in 70.3 and 72.8% of the patients, respectively. The percentage of controlled patients decreased to 64% when both LDLc and TC were considered. Statins and fibrates were prescribed in a small proportion of patients (16.9 and 3.5%, respectively). An acceptable control of blood lipids was achieved in a majority of those patients (60.2%). However a relatively large number of patients (646) with high plasma lipids remained untreated. CONCLUSIONS: Monitoring and intervention strategies on plasma lipid levels in patients with a diagnosis of stroke or TIA need to be improved.

Does gabexate mesilate affect serum concentrations of acute phase proteins after endoscopic retrograde cholangiopancreatography examination?

BACKGROUND/AIMS: To explore the possibility that the preventive effect of gabexate mesilate on endoscopic retrograde cholangiopancreatography-related acute pancreatitis may be mediated by its modulation of acute phase proteins. METHODOLOGY: Thirty consecutive patients who underwent endoscopic retrograde cholangiopancreatography were randomly assigned to receive 1g of gabexate mesilate (13 patients) or a placebo (17 patients) by continuous i.v. infusion starting 30 minutes before the endoscopy session and continuing for 12 hours afterward. In all patients, C-reactive protein, serum amyloid A and interleukin 6 serum concentrations were determined before endoscopy and 4, 8, 12 and 24 hours afterward. RESULTS: Interleukin 6 basal serum concentrations were not statistically different between patients who had been treated with gabexate mesilate and those who had received the placebo (P = 0.279), whereas C-reactive protein (P = 0.033) and serum amyloid A (P = 0.022) basal values were significantly lower in the gabexate mesilate group than in the placebo group. Compared to basal values, serum interleukin 6 concentrations significantly increased at 4 (P = 0.048) and at 8 (P = 0.025) hours; the increase of serum interleukin 6 concentrations was not significant at 12 (P = 0.092), but became significant at 24 (P = 0.025) hours. C-reactive protein and serum amyloid A serum concentrations increased significantly only at 12 (P = 0.001, P = 0.012, respectively) and 24 (P < 0.001, P = 0.013, respectively) hours. The modifications of serum concentrations of interleukin 6, C-reactive protein and serum amyloid A were not significantly different between the gabexate mesilate and the placebo groups. CONCLUSIONS: Gabexate mesilate does not affect serum concentrations of acute phase proteins after endoscopic retrograde cholangiopancreatography examination and it is able to prevent acute pancreatitis related to endoscopic retrograde cholangiopancreatography via a different mechanism than that explored in this study.
