    Abstract:
    The long term efficacy of granulated guar gum, 15-30 g per day, was studied in 23 patients with severe hypercholesterolaemia (serum cholesterol concentration between 8.0 and 14.3 mmol/l). Originally, 29 patients participated in the study. Two patients dropped out because of gastrointestinal side effects, two others were not willing to complete the study without any given reason, and two discontinued the study because of hospitalization. A 1-month placebo period preceded the guar gum treatment, and another 1-month placebo period followed after 50 weeks of active treatment. The serum total cholesterol concentration (mean +/- SEM) was reduced from 10.0 +/- 0.4 mmol/l to 8.2 +/- 0.3 mmol/l (P less than 0.001) after 8 weeks and to 9.0 +/- 0.4 mmol/l (P less than 0.001) after 50 weeks on guar gum. During the second placebo period serum cholesterol returned to the pretreatment level. After 34 weeks of active treatment the serum LDL-cholesterol concentration had fallen by 15% and that of apoprotein B by 14% from the baseline. The changes in lipid and lipoprotein levels were independent of the initial values and the type of hypercholesterolaemia. Serum triglycerides, HDL-cholesterol, body weight and blood pressure showed no significant changes during the trial. Of the study subjects, 20 reached the maximum intended dose of 30 g per day guar gum between 8 and 14 weeks and thereafter 11 subjects continued the dose of 30 g/day while 12 subjects reduced the dose to 15-25 g/day.(ABSTRACT TRUNCATED AT 250 WORDS)
