Dysgammaglobulinaemia in the Elderly - A Review and Case Studies |
|
An understanding of the possible causes of dysgammaglobulinaemia in the elderly helps to direct further investigation to establish a diagnosis. In this review we provide brief case studies to illustrate some of the disorders associated with dysgammaglobulinaemia in the elderly. We consider both hypergammaglobulinaemia (polyclonal, characteristic of chronic inflammatory disorders or autoimmunity, and monoclonal, often with an associated malignant disorder) and hypogammaglobulinaemia (including immunodeficiency, immune paresis secondary to malignancy and protein loss). Where dysgammaglobulinaemia is noted in the elderly the most useful laboratory tools to help discern the pathogenesis are serum and urine electrophoresis, autoantibody investigations and measurement of liver and renal function. |
