Aim: The aim of the study was to explore the potential of phytotherapy with artichoke leaf extract in the management of functional dyspepsia symptoms, a disorder notoriously recalcitrant to pharmacotherapy.
Methods: A cohort of outpatients with a clinical diagnosis of functional dyspepsia and deemed suitable candidates for non-pharmacologic treatment was prospectively observed for 60 days by 33 physicians. Treatment consisted of Cinarepa, a commercial mixture of dry extracts of artichoke leaf (Cynara scolymus) 15% of chlorogenic acid (150 mg per capsule), dandelion radix (Taraxacum officinalis) 2% of inulin, turmeric rhizome (Curcuma longa) 95% of curcumin and rosemary bud essential oil microencapsulated (Rosmarinum officinalis). The severity of 8 dyspepsia symptoms was self-evaluated on a 10-point scale. Blood chemistry testing of lipid profile and liver function was discretionary.
Results: Of the 311 patients in the cohort, the data from 305 (98%) were included in the analysis of dyspepsia symptoms and the data from 50-73 (16-23%) were entered into the analysis of blood chemistry results. A statistically significant gradual reduction in symptom severity was noted at day 30 and further improvement was observed at day 60. Global clinical response, defined as a 50% reduction in the total scores of all symptoms, was recorded in 38% of patients at 30 days and in 79% at 60 days. At 60 days, total cholesterol, LDL and triglyceride levels had decreased by 6-8% over baseline values (P < or = 0.001); transaminase (AST, ALT), and gamma GT concentrations had diminished by 13-20 U/L (P<0.01) in patients with relatively elevated baseline values.
Conclusion: Phytotherapy with Cinarepa holds promise as an alternative option in the relief of functional dyspepsia symptoms and merits further investigation in controlled studies.
