Diagnostic methods Diagnosis is based on family history, physical examination and laboratory investigations that reveal severe thrombocytopenia with reduced platelet size with enfermedsd usually normal number of megakaryocytes, as well as altered antibody production mainly antipolysaccharidic antibodies.

In most cases the first clinical features are hemorrhagic manifestations with petechiae, bruising, purpura, epistaxis, oral bleeding, bloody diarrhea and intracranial bleeding. Severe eczema requires treatment with topical or short-term systemic steroids. Gene therapy, still experimental to date, may be a promising approach for patients lacking a suitable donor.

Agonists of the thrombopoietin receptors such as romiplostim and eltrombopag can be used to increase the platelet count in severe refractory thrombocytopenia cases that are awaiting HSCT or gene therapy. Purine nucleoside phosphorylase deficiency Hyper IgM syndrome 1. Decreased levels of WASp are typically observed.
