Brief Summary

Daily intake of extra virgin olive oil (EVOO), which is the major component of the Mediterranean diet and also a source of monounsaturated fat, may be partly responsible for the increased life expectancy of the Mediterranean people. A high dietary intake of EVOO is correlated with lower incidence of cancer, cardiovascular disease, metabolic diseases, Alzheimer's disease and osteoporosis Oleocanthal, a phenolic derivative of extra virgin olive oil, has important health promoting anti-cancerous properties, since it can inhibit the growth and promote the apoptosis of several cancer cells. The purpose of the present study was to investigate the effect of dietary intake of olive oil rich in oleocanthal on hematological, metabolical, cell progression markers and disease progression in patients with Chronic Lymphocytic Leukemia. The aim is also to study the possible association of apoptosis in the mechanism of action of virgin olive oil phenols in a patient with CLL in order to find the possible mechanism of the cellular action of oleocanthal in neoplasia. After the screening of \>300 EVOO samples the investigators selected an EVOO with high oleocanthal and oleacin concentration of 416 and 284 mg/Kg respectively (EVOO OC/OL). Pilot dietary intervention was made in a group of 21 patients with chronic lymphocytic leukemia (CLL) who did not follow any treatment. EVOO was administered 40 ml/day for six months. Biochemical, hematological and molecular markers were studied six month before the intervention and six month during the intervention

Outcome Measures

Primary Outcomes (2)

  • Effect of the dietary intake of high phenolic EVOO on hematologic profile

    The effect of the dietary intake of high phenolic EVOO on hematologic profile was investigated comparing the complete blood count before (6 and 3 months) at the starting point of the dietary intervention and during (3 and 6 months) the dietary intervention in order to evaluate possible sustained hematologic improvement according to Rai et al criteria. Whole cell blood account was evaluated by hematological analyzer.

    1 year

  • Effect of the dietary intake of high phenolic EVOO on apoptotic markers

    The effect of the dietary intake of high phenolic EVOO on apoptotic markers was investigated comparing the protein expression level on serum of the participants by ELISA. The apoptotic proteins Apo-1/Fas CD 95 (pg/ml) and CCK18 (U/L) and the antiapoptotic protein Survivin (pg/ml) were studied. The mentioned markers were evaluated at the starting point of the intervention, at 3 and 6 months during the dietary intervention with high phenolic EVOO in order to evaluate the in vivo the effect of high phenolic EVOO on protein expression of the studied apoptotic markers in CLL.

    6 month

Secondary Outcomes (4)

  • Effect of the dietary intake of high phenolic EVOO on fasting glucose and correlation with the clinical outcome of the patients with CLL

    1 year

Model Details: Twenty one patients with Chronic lymphocytic leukemia (CLL) from the hematologic clinic of the General hospital of LaKonia (Greece), were enrolled to participate in the dietary intervention. CLL diagnosis was confirmed by standard criteria. Patients were untreated, in Rai stage 0 to II, did not met criteria to initiate chemotherapy and had no neoplasmatic comorbidity. Subjects were randomly selected from the Hematology Department of the General Hospital of Lakonia. Exclusion criteria were neoplastic comorbidities or severe metabolic diseases. Only one group participates in this study, which performed dietary intervention consuming EVOO rich in oleocanthal and oleacin. Clinical and molecular markers were registered 6 months before the intervention and 6 months during the intervention.
