RESUMEN
Introducción. El ictus es una causa principal de mortalidad y discapacidad. El policosanol ha sido efi caz en modelos de isquemia cerebral. Este estudio investiga si el tratamiento a largo plazo con policosanol, añadido a la terapia con ácido acetilsalicílico (AAS), dentro de los 30 días posteriores a un ictus, es mejor que el placebo + AAS en la recuperación de los pacientes. Pacientes y métodos. Estudio aleatorizado, doble ciego, controlado con placebo. Se incluyeron 80 pacientes (edad media: 69 años) que sufrieron un ictus en los 30 días previos y con una puntuación de 2-4 en la escala de Rankin modifi cada(mRS). Se distribuyeron aleatoriamente en dos grupos y recibieron policosanol + AAS o placebo + AAS durante 12 meses. Resultados. El tratamiento con policosanol + AAS disminuyó signifi cativamente la puntuación en la mRS desde el primer control intermedio (1,5 meses). El efecto del tratamiento incluso mejoró con la terapia a largo plazo. El número de pacientes que alcanzaron valores de mRS menores o iguales a 1 fue superior en el grupo de policosanol + AAS (87,5%) que en el de placebo + AAS (0%). El tratamiento con policosanol + AAS aumentó signifi cativamente el índice de Barthel, disminuyó el colesterol LDL y aumentó el colesterol HDL frente a placebo + AAS. Conclusiones. El tratamiento a largo plazo (12 meses) con policosanol + AAS fue más efectivo que el tratamiento con placebo + AAS en la recuperación funcional de los pacientes después de sufrir un ictus isquémico no cardioembólico de moderada gravedad (AU)
Introduction. Stroke is a leading cause of mortality and disability. Policosanol has been eff ective in brain ischemia models. The aim of this study is to investigate whether policosanol, added to aspirin therapy within 30 days of stroke onset, is better than placebo + aspirine for the long-term recovery of non-cardioembolic ischemic stroke subjects. Patients and methods. Randomized, double-blind, placebo-controlled study. Eighty patients (mean age: 69 years) within 30 days of onset, with a modifi ed Rankin Scale score (mRS) 2 to 4, were included. They were randomized in two groups (policosanol + aspirine or placebo + aspirine) for 12 months. Results. Policosanol + aspirine decreased signifi cantly mean mRS from the fi rst interim check-up (1.5 months). The treatment even improved after long-term therapy. More policosanol + aspirin (87.5%) than placebo + aspirine (0%) patients achieved mRSs ≤ 1. Policosanol + aspirine increased signifi cantly Barthel Index, lowered LDL-cholesterol and increased HDL-cholesterol versus placebo + aspirin. Conclusions. Long-term (12 months) administration of policosanol + aspirin given after suff ering non-cardioembolic ischemic stroke was shown to be better than placebo + aspirin in improving functional outcomes when used among patients with non-cardioembolic ischemic stroke of moderate severity (AU)

Context ⢠Nonsteroidal, anti-inflammatory drugs effectively relieve osteoarthritis (OA) symptoms but also induce adverse effects (AEs) that limit their long-term use, which drives a search for safer treatments. D-002, a mixture of beeswax alcohols, and D-003, a mixture of sugarcane wax acids, have been effective in experimental and clinical studies for patients with OA. Objective ⢠The study intended to investigate the effects on OA symptoms of a combined therapy using D-002 and D-003 (D-002/D-003), which were administered for 6 wk. Design ⢠The study was a randomized, double-blind, placebo-controlled trial. Setting ⢠The study was conducted at the Surgical Medical Research Center in Havana, Cuba. Participants ⢠Participants were patients with mild-to-moderate OA. Intervention ⢠Participants were randomly assigned to 1 of 4 groups-(1) a control group, which received a placebo; (2) the D-002 group (intervention group), which received 50 mg/d of D-002; (3) the D-003 group (intervention group), which received 10 mg/d of D-003; or (4) the D-002/D-003 group (intervention group), which received a combined therapy of 50 mg/d of D-002 plus 10 mg/d of D-003. The control group received tablets that were indistinguishable in appearance from the D-002 and D-003 tablets and had a similar composition, except that the active ingredients were replaced by lactose. The groups took the medications once per day for 6 wk. Outcome Measures ⢠Symptoms were assessed using the Western Ontario and McMaster Individual Osteoarthritis Index (WOMAC) and a visual analogue scale (VAS). The primary outcome was the reduction in the total WOMAC score. The subscale scores on the WOMAC for pain, stiffness, and physical function, the VAS scores, and the use of rescue medications were secondary outcomes. Results ⢠Of the 120 enrolled participants, 116 completed the study. The treatments with D-002, D-003, and D-002/D-003 reduced the mean total WOMAC scores significantly from baseline to postintervention, by 75.1%, 72.8%, and 91.2%, respectively. Compared with the placebo, the treatments decreased the mean WOMAC scores for pain, joint stiffness, and physical function significantly. The VAS scores significantly decreased, showing a 71.4%, a 66.9%, and an 84.7% reduction for the D-002, D-003, and D-002/D-003 groups, respectively. All the reductions were significant from the first week and were enhanced during the trial. The D-002/D-003 treatment was more effective in improving all of the scores than either monotherapy. With respect to rescue medications, 3/30, 2/30, and 2/30 used the medications in the D-002, D-003, and D-002/D-003 groups, respectively, vs 17/30 in the control group. The treatments were well tolerated. Conclusions ⢠Administered for 6 wk, 50 mg/d of D-002 and 10 mg/d of D-003 ameliorated OA symptoms, but the combined therapy, D-002/D-003, was more effective than either monotherapy. All treatments were well tolerated.

BACKGROUND/AIMS: Nonalcoholic fatty liver disease (NAFLD) is intimately related to insulin resistance and ranges from a benign course to liver fibrosis and cirrhosis. NAFLD management mainly involves dietary modification and weight loss. Although no fully successful pharmacological intervention is available, alternative therapies to treat NAFLD have shown promising results. Experimental studies have shown that D-002, a mixture of beeswax alcohols with antioxidant effects, is hepatoprotective. The aim of this study was to investigate the efficacy and safety of D-002 in patients with NALFD. METHODS: Fifty patients with NAFLD were randomized to receive a placebo or D-002 (100 mg/day) for 24 weeks. The primary endpoint was a significant ultrasonography-detected reduction of liver fat infiltration versus a placebo. Secondary endpoints were decreases in the homeostatic model assessment (HOMA) index, insulin levels, serum liver enzymes, increases in plasma total antioxidant status (TAS) and improved clinical symptoms versus the placebo recipients. RESULTS: At randomization, all indicators were comparable in both groups. At study completion, seven (28.0%) D-002-patients, but none of the placebo recipients, exhibited a normal liver echo pattern on ultrasonography (p < 0.01). Also, D-002 significantly reduced (p < 0.01 vs. baseline and placebo) the HOMA index and insulin levels and increased the TAS, but did not affect other parameters. The proportion of D-002-patients (12/25, 48.0%) showing symptom improvement was higher (p < 0.001) than that of the placebo group (1/25, 4.0%). The treatment was safe and well tolerated. Three patients in each group withdrew from the study. CONCLUSIONS: D-002 (100 mg/day) improved ultrasonographic findings, indicators of insulin resistance, plasma TAS and clinical evolution on NAFLD patients. Further studies, however, are needed to confirm these results.

The aim of this study was to conduct a randomized, double-blind and placebo-controlled study to investigate the effects of D-004, a lipid extract of the Roystonea regia fruit that prevents testosterone- and phenylepinephrine-induced prostate hyperplasia in rodents, on plasma oxidative markers in healthy men. We enrolled male volunteers (2055 years) in good health and without lower urinary tract symptoms. Thirty-four eligible participants were randomized to placebo or D-004 (320 mg) capsules administered daily for 6 weeks. An interim check-up and a final visit were conducted after 3 and 6 weeks of therapy, respectively. Physical examinations were performed at each visit, and laboratory tests were performed at baseline and at treatment completion. Oxidative variables included plasma malondialdehyde (MDA), total hydroxyperoxides (TOH), sulphydryl (SH) groups and total antioxidant status (TAS). We assessed treatment compliance and addressed adverse experiences (AEs) at weeks 3 and 6. At week 6, with D-004, the mean reductions of plasma MDA (26.7 percent), TOH (18.8 percent) and SH groups (31.6 percent), and the mean increase of TAS (35.3 percent) were significantly different from those of placebo (P < 0.001 for plasma TAS, P < 0.0001 for all other comparisons). D-004 did not differ from the placebo in safety indicators. There were two withdrawals (both in the D-004 group), with one due to dyspepsia (the only AE during the trial). In conclusion, D-004 displayed antioxidant effects on plasma oxidative markers in healthy men, which was consistent with findings from laboratory experimental studies(AU)
