Acute and late effects in the course of and after total body irradiation with following bone marrow transplantation in patients with different forms of leukaemia.

The acute reaction in the course of a total body irradiation (TBI) appears in an organ-specific damage of the stem cells. Moreover, there are unspecified central-nervous stress reactions. Clinical reactions are obtained by the study and symptomatic therapy is proposed. 90 patients with different forms of leukaemia were observed. We documented the course in a specific "protocol system". Reactions like an increase of body temperature, changes of pulse and blood pressure were registered. The occurrence of gastro-intestinal reactions is a typical symptom of the acute radiation syndrome e.g. vomiting and diarrhoea are demonstrated in dependence of the applicated dose of irradiation. Further symptoms of TBI appeared in the later period. Mucositis, parotitis, a decreased function of the salivary glands and diarrhoea as well as vomiting are characterized by different intensity and temporary termination. A difference between allogeneic and autologous transplantation is caused by a medicamental additional treatment. During the late period these symptoms will disappear completely. Moreover, after TBI and BMT late effects are a cataract and some changes in the hormonal system demanding a specific correction or substitution respectively.
