• Infectious Mononucleosis

  The EBV causes several disorders, including infectious mononucleosis. Also, natural killer cells do not function. [msdmanuals.com]

  Thirty-four patients died of infectious mononucleosis, 8 had fatal infectious mononucleosis with immunoblastic sarcoma, 9 had depressed immunity following Epstein-Barr virus infection, and 8 developed lymphoma. [lymphedemapeople.com]

  This X-linked immunodeficiency becomes evident when the patients are infected with Epstein Barr virus (EBV) and develop a fulminant form of infectious mononucleosis leading to a lymphoproliferative syndrome that is often fatal (X-linked lymphoproliferative [pesquisa.bvsalud.org]

  Although hypogammaglobulinemia and malignant lymphoma were associated with longer survivals, no patient had been documented as living into the fifth decade of life. [lymphedemapeople.com]

  Further medical history revealed that the patient received treatment for abdominal Burkitt lymphoma including intravenous immunoglobulins for hypogammaglobulinemia after administration of Rituximab. [thieme-connect.com]

Better treatments are needed urgently. How could this research help? “We are in the laboratory stages of developing a new treatment for XLP,” says Dr Booth. [action.org.uk]

X-linked lymphoproliferative disease is a life-threatening condition that has few treatment options. [sciencedaily.com]

X-linked lymphoproliferative disorder typically presents as an Epstein-Barr virus-specific immune defect with a poor prognosis. [ncbi.nlm.nih.gov]

XLP is a disease with a poor prognosis. Over 70% of patients die by the age of 10 due to fatal infectious mononucleosis. [jstage.jst.go.jp]

Prognosis for those patients has dramatically improved over the decades due to improved lymphoma chemotherapy protocols. [6] Jin YY, Zhou W, Tian ZQ, Chen TX. [emedicine.medscape.com]

Therefore the defect in XLP converts normally activating signals into inhibitory signals. [7, 8, 9, 10] An XLP syndrome caused by mutations in the inhibitor-of-apoptosis gene XIAP has also been reported. [11, 12] Etiology Mutations in the SH2D1A and XIAP [emedicine.medscape.com]

Pathophysiology: In XLP syndrome, the most striking manifestation is that EBV triggers an initial episode of IM that causes death, usually by liver failure secondary to hepatic necrosis, in more than 50% of infected children. [lymphedemapeople.com]

The substantial progress in understanding the XLP pathophysiology was made with revealing the molecular basis of this immunodeficiency. [exp-oncology.com.ua]
