ABSTRACT
En 35 pacientes que debían recibir terapia celular regenerativa se evaluó el efecto estimulante de 2 factores estimuladores de colonias de granulocitos de producción cubana: Hebervital y Leukocim, para la movilización de células madre hematopoyéticas hacia la sangre periférica. Los pacientes se seleccionaron de forma aleatoria en 2 grupos de tratamiento y se les suministró por vía subcutánea una dosis total de 40 mg/kg distribuidos en 4 subdosis de 10 mg/kg administrados cada 12 horas. Se realizó el conteo de las células mononucleares y células CD34+ en sangre periférica mediante citometría de flujo, antes y después de la estimulación. No se encontraron diferencias estadísticamente significativas en los conteos de las células CD34+ obtenidas posestimulación con el Hebervital y el Leukocim(AU)
In 35 patients who should have received regenerative cell therapy, it was evaluated the effect of 2 domestic production granulocyte colony stimulating factors: Leukocim and Hebervital for the mobilization of hematopoietic stem cells into peripheral blood. Patients were randomly selected into 2 treatment groups and were given a total dose of 40 mg/kg in 4 sub-doses of 10 mg/kg subcutaneously administered every 12 hours. Count was performed for mononuclear cells and CD34+ cells in peripheral blood by flow cytometry before and after stimulation. There were no statistically significant differences in the counts of CD34+ cells obtained after stimulation with Hebervital and Leukocim(AU)

To investigate the efficacy and safety of recombinant human epidermal growth factor (rhEGF) in advanced diabetic foot ulcers (DFU) A double-blind trial was carried out to test two rhEGF dose levels in type 1 or 2 diabetes patients with Wagner's grade 3 or 4 ulcers, with high risk of amputation. Subjects were randomised to receive 75 (group I) or 25 mug (group II) rhEGF through intralesional injections, three times per week for 5-8 weeks together with standardised good wound care. Endpoints were granulation tissue formation, complete healing and need of amputation. Safety was assessed by clinical adverse events (AEs) and laboratory evaluations. Forty-one patients were included. After 5-8 weeks of treatment, 83% patients in the higher dose group and 61% in group II achieved useful granulation tissue covering more than 98% of the wound area. At long-term assessment, 13 (56.5%) patients healed in group I and 9 (50%) in group II. The mean time to complete healing in group I was 20.6 weeks (95% CI: 17.0-24.2) and 19.5 weeks (16.3-22.7) in group II. After 1-year follow-up, only one patient relapsed. Amputation was not necessary in 65% and 66.7% of groups I and II, respectively. The AEs rates were similar. The most frequent were sepsis (33%), burning sensation (29%), tremors, chills and local pain (25% each). rhEGF local injection enhances advanced DFU healing and reduces the risk of major amputation. No dose dependency was observed.
