The effect of Cistus incanus herbal tea supplementation on oxidative stress markers and lipid profile in healthy adults.

BACKGROUND: Oxidative stress and dyslipidemia play a critical role in the development of cardiovascular disease (CVD). Regular intake of polyphenol-rich diets is associated with a reduced risk of CVDs. METHODS: The present study was a pilot study with 24 healthy volunteers and was designed to determine if a 12-week administration of Cistus incanus herbal tea, containing phenolic acids and flavonoids, reduces cardiovascular risk factors including oxidative stress and dyslipidemia in healthy adults. Phenolic compounds profile and antibacterial activity of Cistus incanus infusion were also measured. RESULTS: Herbal infusion led to improvement in lipid profile by increase (D4%, p = 0.033) high-density lipoprotein cholesterol concentration and decrease triglyceride (D14%, p = 0.013) concentrations. In addition, the Cistus incanus diet was associated with decreased serum concentrations of malondialdehyde (D16%, p < 0.01) and advanced oxidation protein products (D18%, p < 0.001). CONCLUSIONS: Cistus incanus administration decreases cardiovascular risk factors including oxidative stress and dyslipidemia and this action supports the idea of using Cistus incanus tea on a daily basis as an effective dietary component for prevention of atherosclerotic CVD.

Enteric rods are the microorganisms most commonly isolated from blood of hospitalized patients. Bloodstream infections caused by them are associated with significant patient mortality. The aim of the study was analysis of clinical course and evaluation of clinical response on bloodstream infection caused by Escherichia coli. Microorganisms were evaluated for sensibility for antibacterial drugs. For that reason MIC (Minimal Inhibitory Concentration) of antibiotics from different groups was determined for E. coli strains isolated from patients with different clinical stage of infection. No significant differences were shown in sensitivity for antibiotics and MIC among the E. coli strains in correlation with clinical condition of studied patients.
