Immunobiological allassotherapy is performed with subcutaneous injections of a mixture of old tuberculin and blood of a healthy donor of the same blood group who is highly sensitive to tuberculin and additional BCG injections. The results and experience over 15 years with this treatment show the advantages of this method in a series of patients with proved resistance to therapy and a poor prognosis compared with methods previously possible.
