ABSTRACT
Ninety-two children 5 to 14 years of age living in areas exposed to the radioactive fallout from Chernobyl with recurrent respiratory infections (RRIs) were treated after randomization with either Viscum album praeparatum mali or pini (Iscador M or P). The dosage was two subcutaneous injections a week for 5 weeks with individual doses of 0.001 mg to 1.0 mg. Both Viscum album preparations were effective in significantly reducing clinical symptoms. One year after a single treatment course, the frequency of RRI relapses decreased by 78% and 73%, respectively. Immunomodulatory effects were assessed by investigation of lymphocyte subsets, natural killer (NK) cell activity, phagocytic and oxidative activity of polymorphonuclear leukocytes, and antiviral activity of serum before and 1 week after treatment. Viscum album therapy resulted in normalization of initial immune indices either below or above the normal ranges. High levels of antiviral activity before treatment were significantly decreased by Viscum album mali. Viscum album treatment should be studied further in children with RRI.
