RESUMO
Studies were performed on 21 industry-products sellers suffering to recurrent infections of upper respiratory tract. Immunostimulating treatment was performed using Broncho-vaxom administered during 6 months. Drug was applied by 10 consecutive days every month, 1 tablet at the morning on empty stomach (before breakfast). During immunotherapy the decrease in work-absences and diminution of some pathological symptoms were noted. No additional chemotherapeutics were taken during Broncho-vaxom. Although the efficacy of immunostimulatory therapy with Broncho-vaxom is not certainly proved, treatment with this drug seems to present be an alternative for chemotherapeutics in recurrent infections of upper respiratory tract. That treatment is probably like the psychotherapy.
