This X-linked inherited disorder (thus affecting boys) resulting from a defective gene at Xq25 is characterised by a severe susceptibility to Epstein-Barr virus (EBV) infections.
Following exposure, 75% of patients develop a severe or fatal infectious mononucleosis. Survivors may go on to develop an acquired hypogammaglobulinaema, red cell aplasia, aplastic anaemia or lymphomatoid granulomatosis.[2, 3]
Patients present in childhood (mean age 3-5 years) with signs of EBV infection:
- Respiratory: pharyngitis, lymphoid granulomatosis of lung.
- Abdomen: hepatomegaly, fulminant hepatitis and liver failure, splenomegaly.
- Haematological: atypical mononucleosis (lymphocytosis); thrombocytopenia or bone marrow failure.
- CNS: meningitis or encephalitis, hepatic encephalopathy.
Bone marrow transplant is the definitive treatment.[4, 5] Transplantation of cord-blood stem cells from an HLA-identical sibling has also been successful.
There is research into the use of anti-CD20 rituximab (monoclonal antibody) in the acute phase of EBV infection which shows promise, and cytotoxic chemotherapy may also have a role.
Genetic testing can identify affected individuals and carriers, and antenatal diagnosis is possible.
Without transplant, 70% of patients will not survive beyond 10 years of age.
