A comparative study of broccoli sprouts powder and standard triple therapy on cardiovascular risk factors following H.pylori eradication: a randomized clinical trial in patients with type 2 diabetes

Abstract

Abstract Background In this clinical trial we compared the effects of broccoli sprouts powder, as an alternative and complementary treatment, to those of standard triple therapy, as a common medical treatment, on cardiovascular risk factors following the H.pylori eradication in patients with type 2 diabetes. Methods Eighty-six type 2 diabetic patients with positive H.pylori stool antigen test (HpSAg) were randomized to receive one of the three following regimens: STT) Standard triple therapy (omeprazole 20 mg, clarithromycin 500 mg, amoxicillin 1000 mg, twice a day for 14 days), BSP) 6 g/d broccoli sprouts powder for 28 days, and combination of these as STT + BSP. After 4 weeks of treatment, H.pylori eradication rates were assessed by HpSAg. Anthropometric measures, blood pressure, serum lipids and lipoproteins as well as serum high sensitive- C reactive protein were also assessed at baseline and at the second examination. Results Seventy-seven participants completed the study [STT (n = 28), BSP (n = 25), STT + BSP (n = 24)]. The H.pylori eradication rates were 89.3%, 56.0% and 91.7% in STT, BSP and STT + BSP groups, respectively. After the treatment, both systolic and diastolic blood pressure significantly decreased in STT + BSP group (P < 0.05). Serum triglycerides and TG/HDL-C ratio increased in STT patients group (<0.05). Serum hs-CRP levels significantly decreased in the patients who were treated with BSP per se (3.0 ± 2.5 at baseline vs. 2.3 ± 2.1 after the treatment, P < 0.05). Conclusion Compared to standard triple therapy, BSP regimen in addition to considerable effects on H.pylori eradication had also favorable properties on cardiovascular risk factors following the H.pylori eradication.
