Evaluation of patients suspected of having hypersensitivity pneumonitis induced by exposure to pigeon droppings - Clinical Significance:
Avian proteins, including antigens in pigeon droppings, are a causative agent of hypersensitivity pneumonitis (HP). While the immunopathogenesis of HP is not known, several immune mechanisms are postulated to play a role, including both cellular and humoral mechanisms. - Reference Range:
> or = 16 years: < or = 53.3 mg/L
Interpretive Data:
Elevated concentrations of IgG antibodies to pigeon droppings are consistent with the diagnosis of hypersensitivity pneumonitis caused by exposure to this antigen.Negative results do not rule out the disease.
Elevated concentrations of IgG antibodies to pigeon droppings were found in a small number of sera from patients with hypersensitivity pneumonitis (10%).
Cautions:
IgG antibodies to pigeon droppings are detectable in healthy individuals, and the presence of antibodies is not sufficient to establish the diagnosis of hypersensitivity pneumonitis (HP) caused by exposure to this antigen.The levels of antibodies decrease following successful treatment of HP; but, elevated levels may persist for long periods.
The measurement of IgG antibodies to pigeon droppings should not be relied upon exclusively to establish the diagnosis of HP.
