RESUMO

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) encompasses a spectrum of diseases ranging from steatosis to steatohepatitis and cirrhosis. Given the increasing incidence of NAFLD and the long-term consequences of this disease, it is important to identify the risk factors and therapeutic measures. Abexol is a mixture of beeswax alcohols with antioxidant, gastro-protective and anti-inflammatory effects. The aim was to conduct a pooled analysis of clinical trials data of the effects of Abexol treatment in patients with NAFLD. METHODS: The present analysis includes the data of all patients with NAFLD obtained from medium-term randomized, double-blinded, placebo controlled clinical studies with Abexol. One hundred patients with NAFLD received Abexol (100 mg/day) or placebo for 6 months. Significant changes in the ultrasound analysis of the liver were considered a primary efficacy variable. Secondary endpoints were decreased homeostasis model assessment (HOMA) index and insulin levels, and improved clinical symptoms. Statistical analysis of all data was according to the intention-to-treat method. RESULTS: Both groups were statistically homogeneous at baseline conditions. At 6 months of treatment, the number of Abexol-treated patients exhibiting a normal liver echo pattern on ultrasonography was greater than that of the placebo patients (P < 0.05). Abexol significantly reduced (P < 0.05) insulin levels and HOMA index. The proportion of Abexol patients showing symptom improvement was higher (P < 0.01) than that of the placebo group. Treatments were safe and well tolerated. CONCLUSIONS: Treatment of Abexol during 6 months significantly ameliorates liver fat accumulation and insulin resistances, meanwhile improving clinical evolution in patients with NAFLD. The treatment was safe and well tolerated in these patients.

RESUMO

Introducción: el proyecto Determinantes individuales y sociales de salud en la medicina familiar, concebido con una duración de dos años, se propone desarrollar la opción de evitar la aparición de enfermedades crónicas no trasmisibles interviniendo en los determinantes sociales e individuales de la salud. Objetivo: describir los resultados preliminares después de un año de trabajo en el citado proyecto. Métodos: estudio descriptivo prospectivo en 1 496 individuos dispensarizados en el policlínico universitario Tomás Romay. La muestra se dividió en dos grupos homogéneos: el grupo intervenido, cuyos miembros fueron invitados cuatro veces en el año a una consulta salutogénica y un grupo control, al que se le realizó dos consultas, una al inicio y otra al final del mismo año. Se utilizó una entrevista que actualiza el estado de los determinantes individuales y sociales y permite ofrecer orientaciones salutogénicas. Resultados: en el grupo intervenido disminuyó la frecuencia del tabaquismo (p< 0,0001), el bebedor de riesgo (p< 0,05), el peso (p< 0,05) y el valor del índice de masa corporal (p< 0,05), así como el número de personas con sobrepeso (p< 0,001), la presión arterial diastólica (p< 0,05), y la presión arterial sistólica (p< 0,001). Por otro lado, durante el período de intervención, aumentó la incidencia de diabetes mellitus en el grupo control en comparación con el grupo intervenido (p< 0,05). Conclusiones: los resultados son aun modestos, pero avalan una posibilidad racional para disminuir el riesgo de la aparición de enfermedades crónicas no trasmisibles...

Introduction: the project Individual and social determinants of health in family medicine conceived for two years, is aimed at developing the option of preventing the occurence of non-communicable chronic diseases by intervening in the individual and social determinants of health. Objective: to describe the preliminary results after one-year work in the mentioned project. Methods: prospective and descriptive study of 1 496 subjects classified in Tomas Romay university polyclinics. The sample was divided into two homogeneous groups: the intervened group whose members were invited to salutogenic consultation four times a year, and a control group which went to two consultations, one at the beginning and other at the end of the year. An interview was made to update the state of the individual and social determinants and allowed providing salutogenic guiding. Results: the intervened group reduced the frequency of smoking (p< 0.001), risky drinking (p< 0.05), weight (p< 0.05) and the body mass index (p< 0.05) as well as the number of overweighed persons (p< 0.001), diastolic blood pressure ((p< 0.005), and systolic blood pressure (p< 0.001). On the other hand, the incidence of diabetes mellitus rose during the intervention period in the control group compared with that of the intervened group (p< 0.05). Conclusions: the results are still modest, but they support a rational possibility to diminish the risk of emergence of non-communicable chronic diseases...

RESUMO

El D-002 es una mezcla de 6 alcoholes alifàticos de alto peso molecular purificada de la cera de abejas (Apis mellifera). Este estudio tuvo como objetivo investigar los efectos del tratamiento por vía oral con D-002 sobre las contorsiones abdominales inducidas por àcido acético y en el modelo del plato caliente en ratones. Los animales se distribuyeron aleatoriamente en 5 grupos (10-20 animales/grupo): uno control que recibió el vehículo goma acacia/H2O, tres tratados con D-002 (25, 125 y 250 mg/kg) y uno con aspirina (modelo de contorsiones abdominales) o morfina (plato caliente). El D-002 (25-250 mg/kg) inhibió significativamente las contorsiones inducidas por àido acético en un 44,5; 44,8 y 47,1 por ciento respectivamente; sin embargo, no modificó la latencia de la respuesta en el modelo del plato caliente. Estos resultados muestran que el tratamiento por vía oral con D-002 (25-250 mg/kg) es capaz de inhibir de forma moderada las contorsiones abdominales por àcido acético sin afectar la respuesta al plato caliente. Esto sugiere que el D-002 ejerce una acción analgésica periférica pero no a nivel central.

The D-002 is a mixture of 6 high molecular weight aliphatic acids purified from bee wax (Apis mellifera). The aim of present study was to research the effects of an oral treatment using D-002 on the acetic acid- induced abdominal writhings and in the hot plate model in mice. Animals were randomized distributed to 5 groups (10-20 animals/group): a control one received the Gum Arabic vehicle/H(2)0, three received D-002 (25, 125 and 250 mg/kg), and another received aspirin (abdominal contortions model) or morphine (hot plate). The D-002 inhibited the above mentioned writhings in a 44,5; 44,8 and 47,1 respectively; however, not modified the response latency in the hot plate model. These results demonstrate that the D-002 (25-250 mg/kg) oral treatment may to inhibit in a moderate way the above mentioned writhings without to affect the response to hot plate. It suggests that the D-002 exerts a peripheral analgesic action but not a central level.
