Asplenic patients are at significant risk of infectious complications. The most prevalent pathogens causing infections in this high-risk group include encapsulated bacteria, especially Streptococcus pneumonia.
The most serious form of infection in asplenic patients is septic syndrome, commonly referred to as "overwhelming post-splenectomy infection". All asplenic patients are at the risk of this infection characterised by a highly dramatic clinical course.
However, patients splenectomised for haematological diseases are those at greatest risk in this group. Moreover, the risk of infection is increased by ongoing oncological treatment or immunosuppressive therapy.
The risk of infection can be reduced by simple preventive measures: Adequate patient education and emergency antibiotics, vaccination against selected pathogens according to current recommendations and antibiotic prophylaxis in indicated cases. Based on the updated international recommendations, especially in the field of vaccination, new recommendations of the CzEch Leukemia Study Group for Life (CELL) for the prevention of infectious complications in haematological patients after splenectomy have been drawn up and are presented in this paper.
