An oleuropein-based dietary supplement may improve joint functional capacity in older people with high knee joint pain: findings from a multicentre-RCT and post hoc analysis.

OBJECTIVES: To investigate a 6-month intervention with an olive leaf extract (OLE) on knee functionality and biomarkers of bone/cartilage metabolism and inflammation. DESIGN: This randomized, double-blind, placebo-controlled, multi-centric trial included 124 subjects with knee pain or mobility issues. Subjects received twice a day one capsule of placebo or 125 mg OLE (Bonolive™, an OLE containing 50 mg of oleuropein) for 6 months. The co-primary endpoints were Knee injury and Osteoarthritis Outcome Score (KOOS) and serum Coll2-1NO2. The secondary endpoints were the subscales of the KOOS, knee pain VAS at rest and at walking, OARSI core set of performance-based tests and multiple inflammatory and bone or cartilage remodeling serum biomarkers and concentration of oleuropein's metabolites in urine. RESULTS: At 6 months, OLE group was not efficient on global KOOS score, changes of inflammatory and cartilage remodeling biomarkers compared to placebo. Post hoc analyses demonstrated a large and significant treatment effect of OLE in a sub-group of subjects with high walking pain at baseline (p = 0.03). This was observed at 6 months for the global KOOS score, and each different subscale and for pain at walking (p = 0.02). OLE treatment was well tolerated. CONCLUSION: OLE was not effective on joint discomfort excepted in a sub-group of subjects with high pain at treatment initiation. As oleuropein is well tolerated, OLE can be used to relieve knee joint pain and enhance mobility in subjects with articular pain.

A Randomized Study to Compare a Monthly to a Daily Administration of Vitamin D3 Supplementation.

We aimed to determine whether a cumulative dose of vitamin D3 produces the same effects on the serum concentration of 25(OH)D3 if it is given daily or monthly. This is a monocentric, two-armed, randomized, interventional, open, and parallel study conducted from November 2016 to March 2017 in Belgium. We randomized 60 subjects with vitamin D deficiency to receive 2000 IU vitamin D3 daily or 50,000 IU monthly. The same cumulative dose of vitamin D3 was given to each treatment group (150,000 IU). The 25(OH)D3 serum concentrations from baseline to day 75 were 14.3 ± 3.7 to 27.8 ± 3.9 ng/mL in the monthly group and 14.1 ± 3.4 to 28.8 ± 5.4 ng/mL in the daily group. The mean change versus the baseline level was significantly different between the groups at day 2, 4, 7, and 14 and no longer different from day 25. One day after the intake of vitamin D3, as expected, serum 25(OH)D3 and 1,25(OH)2D3 increased significantly in the monthly group, whereas they did not change significantly in the daily group. The median time to reach the 20 ng/mL target concentration was significantly different in the two groups, in favor of the monthly regimen (1 day versus 14 days; p = 0.02). In conclusion, a monthly administration of 50,000 IU vitamin D3 provides an effective tool for a rapid normalization of 25(OH)D3 in deficient subjects. A daily administration of the same cumulative dose is similarly effective but takes two weeks longer to reach the desirable level of 20 ng/mL.

[Cardiorenal protection with SGLT2 inhibitors (gliflozins) : from EMPA-REG OUTCOME to CANVAS]. / Protection cardio-rénale par les inhibiteurs des SGLT2 (gliflozines) : d'EMPA-REG OUTCOME à CANVAS.

The cardiovascular (CV) and renal protection reported with empagliflozin in EMPA-REG OUTCOME is now confirmed with canagliflozin in CANVAS in patients with type 2 diabetes and high cardiovascular risk: similar and significant reductions in major CV events (-14 vs. -14%), in hospitalisations for heart failure (-35 vs. -33%) and in renal events (-39 vs. -40%). The greater reduction in CV mortality (-38 vs. - 13%) and all-cause mortality (-32 vs. -13%) in EMPA-REG OUTCOME than in CANVAS may be explained by the greater proportion of patients with CV disease (secondary prevention : 99 vs. 65%). In contrast to EMPA-REG OUTCOME, CANVAS did not show an increase in stroke (-10%, NS), but reported a higher rate of fractures and amputations with canagliflozin. Overall, these results support a class effect for the cardiorenal protection by inhibitors of sodium-glucose type 2 (SGLT2) cotransporters.

La protection cardiovasculaire (CV) et rénale rapportée avec l'empagliflozine dans EMPA-REG OUTCOME est confirmée avec la canagliflozine dans le programme CANVAS chez des patients diabétiques de type 2 à haut risque CV : réduction significative des événements CV majeurs (­ 14 vs ­ 14%), des hospitalisations pour insuffisance cardiaque (­ 35 vs ­ 33%) et des événements rénaux (­ 39 vs ­ 40%). La plus grande réduction de la mortalité CV (­ 38 vs ­ 13%) et de la mortalité globale (­ 32 vs ­ 13%) dans EMPA-REG OUTCOME que dans CANVAS pourrait être due à une proportion différente de patients en prévention secondaire (99 vs 65%). CANVAS n'a pas montré d'augmentation des accidents cérébrovasculaires (­ 10%), mais un risque accru de fractures et d'amputations. Globalement, ces résultats plaident pour un effet de classe des inhibiteurs des cotransporteurs sodium-glucose de type 2 (SGLT2).

A Randomised, Cross-Over Study to Estimate the Influence of Food on the 25-Hydroxyvitamin D3 Serum Level after Vitamin D3 Supplementation.

Vitamin D3 is known to be liposoluble and its release could be a factor limiting the rate of absorption. It was presumed that the presence of fat could favor absorption of vitamin D3. However, as bioavailability is related not only to the active molecules but also to the formulations and excipients used, the optimization of the pharmaceutical form of vitamin D3 is also important. The objective of this study was to evaluate if there is a food effect on absorption when a high dose of vitamin D3 is completely solubilized in an oily solution. In the present cross-over study, 88 subjects were randomized and received a single dose of 50,000 IU of vitamin D3 in fasting state or with a standardized high-fat breakfast. Assessment of serum concentrations of 25 hydroxyvitamin D3 (25(OH)D3) was performed three, five, seven, 14, 30 and 60 days after supplementation. In fed and fast conditions, the 25(OH)D3 serum concentrations were significantly higher than the baseline value three days after administration and remained significantly higher during the first month. No significant difference between fasting vs. fed conditions was observed. It is therefore concluded that the vitamin D3 absorption from an oily solution was not influenced by the presence or absence of a meal.

[Cardiovascular protection of patients with type 2 diabetes : from EMPA-REG OUTCOME to LEADER]. / Protection cardiovasculaire du patient diabétique de type 2 : d'EMPA-REG OUTCOME à LEADER.

Two clinical trials demonstrate the superiority versus a placebo of two antidiabetic drugs in patients with type 2 diabetes and high cardiovascular risk. Empagliflozin, an inhibitor of sodium-glucose type 2 (SGLT2) cotransporters, in EMPA-REG OUTCOME, and liraglutide, an agonist of glucagon-like peptide-1 (GLP-1) receptors, in LEADER, showed a significant reduction in major cardiovascular events (- 14 and - 13 %, respectively), cardiovascular mortality (- 38 and - 22 %, respectively) and all-cause mortality (- 32 and - 15 %, respectively). A lower progression of kidney disease and less renal events were also reported. The underlying protective mechanisms remain controverted as the discussion whether the benefits are specific to each medication or could be extended to other molecules of these two pharmacological classes.

Deux essais cliniques ont démontré la supériorité versus un placebo de deux médicaments antidiabétiques chez des patients diabétiques de type 2 à haut risque cardiovasculaire. L'empagliflozine, un inhibiteur sélectif des cotransporteurs sodium-glucose de type 2 (SGLT2), dans l'étude EMPA-REG OUTCOME, et le liraglutide, un agoniste des récepteurs du glucagon-like peptide-1 (GLP-1), dans l'étude LEADER, ont montré une réduction significative des événements cardiovasculaires majeurs (respectivement, ­ 14 et ­ 13 %), de la mortalité cardiovasculaire (­ 38 et ­ 22 %) et de la mortalité globale (­ 32 et ­ 15 %). Les mécanismes sous-jacents expliquant le meilleur pronostic avec ces deux médicaments restent discutés, de même que le fait de savoir s'il s'agit d'un effet propre à chacune des molécules ou d'un effet attribuable à la classe pharmacologique.

A Randomized, Double-Blind, Parallel Study to Evaluate the Dose-Response of Three Different Vitamin D Treatment Schemes on the 25-Hydroxyvitamin D Serum Concentration in Patients with Vitamin D Deficiency.

Many people worldwide are vitamin D (VTD) deficient or insufficient, and there is still no consensus on the dose of VTD that should be administered to achieve a 25(OH)D concentration of 20 or 30 ng/mL. In this study, we aimed to determine an adapted supplementation of VTD able to quickly and safely increase the vitamin D status of healthy adults with low 25(OH)D. One hundred and fifty (150) subjects were randomized into three groups, each to receive, orally, a loading dose of 50,000, 100,000 or 200,000 IU of VTD3 at Week 0, followed by 25,000, 50,000 or 100,000 IU at Week 4 and Week 8. Whereas 25(OH)D baseline values were not different between groups (p = 0.42), a significant increase was observed at Week 12 (p < 0.0001) with a mean change from baseline of 7.72 ± 5.08, 13.3 ± 5.88 and 20.12 ± 7.79 ng/mL. A plateau was reached after eight weeks. No related adverse event was recorded. This study demonstrated a linear dose-response relationship with an increase in 25(OH)D levels proportional to the dose administered. In conclusion, a loading dose of 200,000 IU VTD3 followed by a monthly dose of 100,000 IU is the best dosing schedule to quickly and safely correct the VTD status.
