Description | Ig-G4 related disease is a heterogeneous disorder with multi-organ involvement recognised as a separate entity at the start of this century only. Almost all organs can be involved by this disease, but mostly is manifested in gastrointestinal trakt and pankreas. In some patients it can cause retroperitoneal fibrosis and in some patients may be present as lymfadenopathy. Diagnosis involves establishing high circulating levels of IgG4 > 135 mg/dL, increased serum IgG4 to IgG ratio of > 8%, immunohistochemistry showing dense lymphoplasmacellular inflammatory infiltrate consisting of IgG4-positive plasma cells with storiform fibrosis and obliterative phlebitis, and increased IgG4 positive plasma cell. Glucocorticoids are the primary form of therapy. Rituximab is the second line of therapy in case of no responce to kortikosteroids or intolerance of corticosteroids. |
