Dietary Intervention With High Phenolic EVOO in CLL

Effect of Dietary Intervention With High-Oleocanthal and Oleacin Extra Virgin Olive Oil in Patients With Chronic Lymphocytic Leukemia a Pilot Study

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.

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.

The effect of the dietary intake of high phenolic EVOO on fasting glucose (mg/dL), was investigated comparing the fasting glucose before the intervention (6 and 3 months) at the starting point of the intervention, at 3 and 6 months during the dietary intervention with high phenolic EVOO. The correlation of the changes on the fasting glucose during the survey with the hematological outcome of the patient with CLL was also investigated.

The effect of the dietary intake of high phenolic EVOO on lipidemic profile (cholesterol (mg/dl), Low density lipoprotein (LDL- mg/dl), Hight density lipoprotein (HDL mg/dl), tryglicerides (mg/dl) was investigated comparing the lipidemic profile before the intervention (6 and 3 months) at the starting point of the intervention, at 3 and 6 months during the dietary intervention with high phenolic EVOO. The correlation of the changes on the lipidemic profile during the survey with the clinical outcome of the patient with CLL was also investigated.

The effect of the dietary intake of high phenolic EVOO on liver function was investigated comparing the biochemical markers of the liver function (Serum glutamic pyruvic transaminase (SGPT (U/L)), Serum glutamic oxaloacetic transaminase (SGOT(U/L) ), lactate dehydrogenase (LDH(U/L)), alkaline phosphatase (ALP(U/L)), gamma-glutamyl transferase (γ-GT(U/L) before the intervention (6 and 3 months) at the starting point of the intervention, at 3 and 6 months during the dietary intervention with high phenolic EVOO. The correlation of the changes on the liver function during the survey with the clinical outcome of the patient with CLL was also investigated.

The effect of the dietary intake of high phenolic EVOO on kidney function was investigated comparing the conventional biochemical markers of the kidney function Urea(mg/dl) and creatinine (mg/dl ) before the intervention (6 and 3 months) at the starting point of the intervention, at 3 and 6 months during the dietary intervention with high phenolic EVOO. The correlation of the changes on the kidney function during the survey with the clinical outcome of the patient with CLL was also investigated.

There is not a plan to make Individual participant data (IPD) available.

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.

Virgin olive oil obtained by traditional procedures (VOO);

Optimized virgin olive oil with a high phenolic content (OHPCO);

Functional olive oil (FOO) with both high phenolic compounds and triterpene content.

Cardiovascular Diseases

VOO was sequentially administered over 3 periods of 3 weeks preceded by 2-week washout periods in which participants were requested to avoid olives and olive oil consumption. During intervention periods, they were requested to ingest a raw daily dose of 30 mL of VOO distributed over 3 meals. Daily doses of VOO were blindly prepared in special containers, with the corresponding 30 mL VOO daily dose were delivered at the beginning of each intervention period to the participants. The participants were instructed to return the containers when collecting the next daily doses for the amount of unconsumed VOO to be registered. During washout periods participants were provided of sunflower oil for raw and cooking purposes.

OHPCO was sequentially administered over 3 periods of 3 weeks preceded by 2-week washout periods in which participants were requested to avoid olives and olive oil consumption. During intervention periods, they were requested to ingest a raw daily dose of 30 mL of OHPCO distributed over 3 meals. Daily doses of OHPCO were blindly prepared in special containers, with the corresponding 30 mL OHPCO daily dose were delivered at the beginning of each intervention period to the participants. The participants were instructed to return the containers when collecting the next daily doses for the amount of unconsumed OHPCO to be registered. During washout periods participants were provided of sunflower oil for raw and cooking purposes.

Optimized High Phenolic Content Oil (OHPCO)

FOO was sequentially administered over 3 periods of 3 weeks preceded by 2-week washout periods in which participants were requested to avoid olives and olive oil consumption. During intervention periods, they were requested to ingest a raw daily dose of 30 mL of FOO distributed over 3 meals. Daily doses of FOO were blindly prepared in special containers, with the corresponding 30 mL FOO daily dose were delivered at the beginning of each intervention period to the participants. The participants were instructed to return the containers when collecting the next daily doses for the amount of unconsumed FOO to be registered. During washout periods participants were provided of sunflower oil for raw and cooking purposes.

measured with a mercury sphygmomanometer after a minimum of 10 minutes rest in the seated position; the average of two measurements was taken for analysis.

a potential confounder variable concerning oxidative and anti-inflammatory status was recorded at the beginning and at the of the study, and assessed by the Minnesota Leisure Time Physical Activity Questionnaire validated for its use in Spanish men and women

determined in plasma by ELISA using two antibodies against antigenic determinants of oxidized apolipoprotein B molecule (ox-LDL, Uppsala, Sweden)

measured spectrophotometrically at 234 nm and 300 nm after Cu++ oxidation

measured as markers of compliance of the intervention, will be determined by gas chromatography-mass spectrometry

Endothelial function was measured at baseline (0h) and at 4 and 6h after each olive oil administration. Peripheral arterial tonometry signals were obtained using a device. Finger probes were placed on the middle finger of each subject's hand. These probes comprised a system of inflatable latex air cuffs connected by pneumatic tubes to an inflating device controlled through a computer algorithm. A constant counter pressure (pre-determined by baseline diastolic blood pressure) was applied. There was no occlusion of arterial blood flow. Pulsatile volume changes of the distal digit induced pressure alterations in the finger cuff, which were sensed by pressure transducers and transmitted to and recorded by the device. A decrease in the arterial blood volume in the distal finger tip caused a decrease in pulsatile arterial column changes, reflected as a decrease in the measured PAT signal.
