Effects of pindolol and propranolol on blood lipids in hypertensive patients.

Since beta-blockers could affect lipid levels at the therapeutic dose range in hypertensive patients, a parallel 6-month randomized trial with pindolol (PDL) (16 pts.) and propranolol (PPL) (23 pts.) was designed (mean age = 55 + 7.1 years and 57 + 8.0 years; 9 males, 7 females and 15 males, 8 females, respectively). Total cholesterol, LDL and HDL fractions, and triglycerides (TGs) were determined before (washout phase) and during 1, 3, and 6 months of therapy. Patients were instructed to maintain their usual dietary habits. Daily drug doses were adjusted step by step to attain an optimal hypotensive effect (PDL 15-45 mg, PPL 180-240 mg). In the PPL-treated group, total cholesterol and LDL did not change significantly, HDL decreased (from 45.2 to 40.5 mg/dl, p less than 0.05) and TG increased (from 133 to 169 mg/dl, p less than 0.05). In the PDL group total cholesterol and LDL did not change either, but HDL increased (35.9 to 44.7 mg/dl, p less than 0.01) and TGs, were reduced (from 169 to 131 mg/dl, p less than 0.05). No dose-effect relationship was recorded. It is concluded that pindolol does not negatively influence HDL nor the TG blood lipid profile as does PPL. Accordingly, pindolol might be preferred to propranolol in the treatment of hypertensive patients with an unfavorable lipid profile, but this assumption remains to be proven in larger, prospective, long-term followup trials.

Effects of pindolol and clopamide on blood lipids in arterial hypertensive patients.

The effects of clopamide, pindolol and its combination on plasma lipids in 49 hypertensive patients (WHO I-II), divided into three parallel randomized groups, were studied over a 6 months period. Total cholesterol, triglycerides, HDL and LDL cholesterol fractions were determined twice during an initial 4-week washout phase, and after a 1-, 3- and 6-month active hypotensive drug phase. Patients were instructed to maintain their usual dietary habits. Daily drug doses were adjusted progressively to attain optimal hypotensive effects. In the clopamide monotherapy group, total cholesterol increased significantly (p less than 0.05); triglycerides and LDL showed a tendency to increase while for HDL a tendency to decrease was observed. In the pindolol monotherapy group, a significant reduction of triglycerides (p less than 0.01) and a significant increase of HDL cholesterol (p less than 0.05) were recorded. No significant changes in total cholesterol or LDL fraction were observed. Combined pindolol-clopamide therapy decreased total triglycerides (NS), increased HDL significantly (p less than 0.05) and did not influence total cholesterol and LDL fraction. It is concluded that pindolol does not negatively influence blood lipids as the thiazide-type diuretic clopamide does, and that when both drugs are used together, the beta-blocker can probably counterbalance the diuretic-induced negative effects on blood lipids. Accordingly, it is suggested that pindolol could be a more favorable beta-blocker drug to be used on hypertensive subjects with metabolic coronary risk factors.

Glucose tolerance and the insulin response in recently drinking alcoholic patients: possible effects of withdrawal.

To investigate possible effects of withdrawal on carbohydrate metabolism in chronic alcoholic patients, intravenous glucose tolerance tests were performed in three periods in 11 alcoholic patients: early abstinence (less than three days), early abstinence plus ethanol (1 g/kg/BW IV), and late abstinence (three weeks later). According to liver biopsy results and laboratory tests, patients were classified as a group with liver damage (four cases) and a group without it (seven cases). In the group without damage, glucose tolerance expressed as K% and compared to a control group, was significantly decreased in early and late abstinence but not after the infusion of ethanol. Cases with damage also had glucose intolerance at admission. Plasma insulin levels after the glucose load were significantly lower at ten and 30 minutes in the group without damage, in early or late abstinence. They were normal in the presence of ethanol. Patients with liver damage presented higher basal and postglucose plasma insulin concentrations. It was concluded that glucose intolerance in alcoholic patients is a common finding that occurs in the presence or absence of liver damage. In cases with liver damage it seems to be due to peripheral insulin resistance. In those without damage it is related to low peripherovenous insulin levels.
