In approximately 51–70% of people with this disease, serum Ig G4 concentrations are elevated during an acute phase. It is a relapsing–remitting disease associated with a tendency to mass forming, tissue-destructive lesions in multiple sites, with a characteristic histopathological appearance in whichever site is involved.

IgG4-related disease IgG4-RD is considered a systemic, chronic and inflammatory disorder that is characterized by the enlargement of involved organs, elevated levels of IgG4 and abundant infiltration of plasmacytes with IgG4 and fibrosis in involved organs. Hydroxychloroquine Plaquenil is considered a disease-modifying anti-rheumatic drug DMARD. It can decrease the pain and swelling of arthritis. It may prevent joint damage and reduce the risk of long-term disability. Hydroxychloroquine is in a class of medications that was first used to prevent and treat malaria. Ig G4-related disease has been described as an indolent condition. Inflammation and the deposition of connective tissue in affected anatomical sites can lead to organ dysfunction, or even organ failure, if not treated.

IgG4-Related Disease IgG4-RD is an emerging disorder often associated with exuberant hypergammaglobulinemia, and this review of seven cases establishes IgG4-RD as an important cause of polyclonal HVS. IgG4-related disease IgG4-RD, formerly known as IgG4-related systemic disease, is a chronic inflammatory condition characterized by tissue infiltration with lymphocytes and IgG4-secreting plasma cells, various degrees of fibrosis scarring and a usually prompt response to oral steroids.
