ABSTRACT

Se realizó un ensayo clínico fase III, multicéntrico, abierto, paralelo, aleatorizado y controlado, para evaluar la eficacia y seguridad del OLEOZON® tópico (aceite de girasol ozonizado) en el tratamiento de pacientes con impétigo. Se conformaron 2 grupos: uno tratado con OLEOZON® y otro con crema de Mupirocina 2%. Ambos tratamientos se aplicaron de forma tópica, 3 veces al día hasta la cura de las lesiones o hasta un máximo de 10 días. Se incluyeron 136 niños de 0 a 14 años de edad con diagnóstico clínico y bacteriológico de impétigo, vírgenes de tratamiento o con al menos 72 horas sin tratamiento específico tópico o sistémico y con el consentimiento de sus padres. Para determinar la eficacia se realizó la prueba unilateral de equivalencia de las proporciones a la variable principal del estudio: respuesta clínica. La seguridad del tratamiento fue evaluada a través del tipo e intensidad del evento adverso. De acuerdo al análisis realizado la proporción de pacientes curados clínicamente en el grupo OLEOZON® no resultó inferior en un 20% a la proporción de pacientes curados en el grupo de Mupirocina, por lo que se consideran tratamientos equivalentes. Un 92.9% (39/42) de los pacientes del grupo OLEOZON® curaron, mientras que en el grupo de Mupirocina el 100% de los pacientes (59/59) lograron igual respuesta. Ambos tratamientos resultaron ser seguros a las dosis según el esquema de administración aplicados en el estudio.

ABSTRACT

Interferon alfa (IFN-alpha) is the only approved treatment for chronic hepatitis B (HBV) infection. In a non-controlled study 33 pediatric patients infected with HBV and in chronic phase of the disease were included and treated with 3 to 5 x 10(6) IU/m2 body surface of Interferon alpha 2b, 3 times per week, during 4 months. The objective was to evaluate the efficacy of the treatment in terms of the histological, biochemical and viral markers evolution of the patients. The patients were evaluated carrying out determinations of alanine aminotransferase (ALAT), HBsAg and HBeAg before treatment, at the end of the treatment and every 4 months during one year of follow-up. Liver biopsy and Knodell index determination were carried out at the beginning and upon concluding the follow-up. 39.3% of the patients concluded the treatment with normal ALAT values; 7% became HBsAg negative and 14.3% became HBsAg negative. These values ascended after follow-up to 51.5%, 11% and 37.5% respectively. The histological analysis evidenced a decrease of the Knodell index in 69% of the patients, an increase in 14.2%, and 13.8% did not show variation. Correlating the biochemical and histological responses, a favorable outcome was obtained in 36.4% of the patients, evidencing a remarkable reduction of the hepatic cytolysis. The treatment was well tolerated, being the fever the most frequent adverse events. The results confirm that interferon alfa seems to be an effective treatment for children with chronic hepatitis B
