A retrospective analysis of bleeding complications in 438 patients with acute leukaemia during the years 1972–1991

: The incidence and mortality of bleeding complications have been investigated in 438 patients with acute leukaemia consolidated either by chemotherapy (n = 241) or by bone marrow transplantation (n = 197). Bleeding signs on admission were found in 38% of the chemotherapy-treated group. Haemorrhagic deaths during the 1st month were seen in 10%. The majority of the major bleedings were localized intracranial, but gastrointestinal haemorrhages were also common. The platelet count was significantly lower (40 × 109/1 versus 69 × 109/1, p < 0.001) and the leukocyte count significantly higher (31.2 × 109/1 versus 11.6 × 109/1, p<0.001)in the group with bleeding complications than in those without. The haemorrhagic mortality in patients consolidated with chemotherapy compared with transplant patients was similar, 23% and 19%. The majority of the lethal haemorrhages in the latter group were observed in patients undergoing allogenic bone marrow transplantation after engraftment. Septicaemia, graft-versus-host and venous occlusive disease were contributing factors.
