8-epi-muralioside, an iridoid glucoside from Linaria arcusangeli

A new polyhydroxylated iridoid glucoside, 1, was isolated from Linaria arcusangeli. The structure of 1 could arise from a regioselective acid-catalyzed-like opening of the epoxide ring of antirrhinoside, the main iridoid constituent of the plant. Compound 1 is the 8-epimer of muralioside, previously isolated from Cymbalaria muralis

Effectiveness and Safety of Novel Nutraceutical Formulation Added to Ezetimibe in Statin-Intolerant Hypercholesterolemic Subjects with Moderate-to-High Cardiovascular Risk

The effectiveness of statins in the primary and secondary prevention of cardiovascular (CV) diseases has been widely proven. However, the onset of adverse events associated with their use prevents to achieve the therapeutic targets recommended by the guidelines (GL) for the management of dyslipidemia. In the event of statin intolerance, the GL recommend to use bile acid sequestrants, fibrates, and ezetimibe in monotherapy, but their benefits in improving lipid pattern are quite modest. This study aims at evaluating the effectiveness and safety of a nutraceutical compound (NC) associated with ezetimibe (EZE) on the lipid profile in statin-intolerant patients with moderate-to-high CV risk. Ninety-six statin-intolerant hypertensive and hypercholesterolemic subjects treated pharmacologically with EZE 10 mg daily were randomized in open label (n = 48) to take for 3 months a NC containing Monacolin-K (MK), Berberine Hydrochloride (BC), t-Resveratrol (RES), Quercetin (QUER), and Chromium (CH) in the form of a gastro-resistant tablet that improves enteric bioaccessibility and bioavailability of these substances. The control group (n = 48) took only EZE in monotherapy at the same dosage; both groups followed a standardized lipid-lowering diet. The total serum cholesterol (TC), low density lipoprotein cholesterol (LDLC), high density lipoprotein cholesterol (HDLC), triglycerides (TG), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and creatinine phosphokinase (CPK) levels were compared at the follow-up in both groups using Student's t-test. TC and LDL levels reduced in both groups, but were lower in the group treated with EZE + NC (-25.9% vs. -15%, P < .05 and -38.7% vs. -21.0%, P < .05, respectively). No changes were observed in either group regarding a decrease in TG (-9.4% vs. -11.7%, NS) and an increase in HDLC (+4.2% vs. +1.1%, NS). The AST, ALT, and CPK levels increased in the group treated with the EZE + NC compared to the control group, but were still within the acceptable range. There was no difference concerning the lipid-lowering treatment between gender, and no patient withdrew from the study. In the short term, the EZE + NC combination therapy is well tolerated and effective in improving TC and LDLC levels in statin-intolerant patients with moderate-to-high CV risk

Lactobacillus Kefiri LKF01 (Kefibios^®) for Prevention of Diarrhoea in Cancer Patients Treated with Chemotherapy: A Prospective Study

Diarrhoea is one of the main side effects that cancer patients face. The literature showsthat the incidence of chemotherapy (CT)-induced diarrhoea (grade 3–4) in treated patients is in the range of 10–20%, particularly after 5-fluorouracil (5-FU) bolus or some combination therapies of irinotecan and fluoropyrimidines. The aim of the present study was to evaluate the clinical effectiveness of Lactobacillus kefiri LKF01 (Kefibios®) in the prevention or treatment of CT-related diarrhoea in the cancer population. We conducted a prospective observational study. Patients enrolled were adults treated for at least four months with 5-FU-based CT. Kefibios® was administered to patients every day. The primary outcome was the evaluation of the incidence of grade 3–4 CT-induced diarrhoea. We included 76 patients in the final analysis. A 6.6% incidence of high-grade diarrhoea was found in the evaluated population (4.7% of patients treated with 5-FU-based therapy and 8.5% of patients treated with capecitabine-based CT). The overall incidence of high-grade diarrhoea observed was higher in the 1st and 2nd cycles (3.9%), with a subsequent sharp reduction from the 3rd cycle (1.3%) and negativisation from the 5th cycle. Lactobacillus kefiri LKF01 (Kefibios®) is safe and effective in preventing severe diarrhoea in cancer patients receiving 5-FU or capecitabine-based treatment
