Causes
Asplenia is caused by either congenital, acquired conditions, or functional.
Common Causes
Acquired
- Acquired asplenia associated after trauma or surgery, is one of the commonest cause of the absence of splenic tissue.[1]
- Functional asplenia include diseases such as sickle cell (SC) disease, hemoglobin SC disease and sickle beta-thalassemia.[2]
- Hyposplenia occurs due to medical conditions such as chronic liver disease, human immunodeficiency syndrome (HIV), malignancies, thalassemia, celiac disease, ulcerative colitis, sarcoidosis, amyloidosis, lupus, rheumatoid arthritis.[3]
Less Common Causes
Congenital
- Congenital asplenia may be isolated or usually seen as a clinical syndrome such as ivemark syndrome. This syndrome is classified under heterotaxy syndrome. It is associated with malformation of the heart, and abnormal arrangements of organs of the chest and abdomen along with asplenia or hypoplasia of the spleen.[4]
- Isolated asplenia are rare and etiology was genetic, due to mutations in the gene RPSA, which encodes ribosomal protein SA, cause more than half of the cases of isolated congenital asplenia, which was first discovered in 2013.
- In heterotaxy syndrome Two human genes, connexin 43 and ZIC3, have been shown to be involved.
- congenital asplenia a very rare anomaly that has been reported in both infants and adults.
- Infantile cases are almost invariably associated with serious congenital malformations of the cardiovascular, gastrointestinal, and pulmonary systems that are not compatible with long life.
- These include atrioventricular communist, pulmonary stenosis or atresia, anomalies of the aorta and great vessels, complete or partial situs in versus, anomalies of the mesenteric and accessory lobes of the lungs.
- In the adult splenic agenesis is usually an isolated and unexpected finding.
