Overwhelming sepsis remains a significant complication of asplenia and hyposplenia. The mainstays of prevention are education, immunization, and prophylactic antibiotics. Evidence to base recommendation and guidelines is lacking. Such decisions as the specific immunizations required, the timing of immunizations, the duration of antibiotic prophylaxis, and the prevention of overwhelming postsplenectomy sepsis in children undergoing splenectomy are often empiric. This article reviews the current literature on the prevention and management of severe infections in children with underlying asplenia or hyposplenia.

Sickle cell disease patients are prone to infection and overwhelming sepsis because an immunedeficient state arises from asplenia (autosplenectomy/surgical splenectomy) and functional hyposplenism. The common pathogen encountered in sepsis with asplenic/hyposplenism patients is encapsulated organism, gram-negative bacilli, but in developing countries like India, there are many possibilities of infection by an uncommon organism that make it difficult to diagnose. Here, we have described a case of sickle cell disease presented with persistent fever and later, found to have an atrophic spleen with involvement of respiratory system and osteoarticular system.

The spleen is located in the left upper quadrant of the abdominal cavity and has both immunological and haematological functions. A variety of quite different entities may be associated with sudden death due to splenic involvement. These range from simple traumatic disruption of the parenchyma of a normal spleen with marked intra-abdominal haemorrhage, to conditions such as malaria and infectious mononucleosis where splenomegaly predisposes to rupture.

Article Synopsis
- Functional hyposplenia/asplenia is often overlooked but leads to immunodeficiency and is diagnosed using technetium-99m scintigraphy.
- The presence of pitted erythrocytes or Howell-Jolly bodies indicates this syndrome and its association with a reduced spleen size.
- This review focuses on the benefits of B-mode and contrast-enhanced ultrasound for detecting immunodeficiency linked to functional hyposplenism.

Sickle cell disease (SCD) is caused by a point mutation in the beta-globin gene. SCD is characterized by chronic hemolytic anemia, vaso-occlusive events leading to tissue ischemia, and progressive organ failure. Chronic inflammatory state is part of the pathophysiology of SCD.

Purpura fulminans (PF) is a skin disorder with high morbidity and mortality which is characterized by microvascular thrombosis and development of hemorrhagic necrosis. PF can be caused by acute infection, most commonly due to , followed by . Prior reports describe cases of pneumococcal PF occurring in patients with asplenia or hyposplenia, though cases have also been reported in otherwise healthy adults without known splenic disease.
