  • Title: Alveolar macrophage gold retention in rheumatoid arthritis.
    Author: Garcia JG, Munim A, Nugent KM, Bishop M, Hoie-Garcia P, Parhami N, Keogh BA.
    Journal: J Rheumatol; 1987 Jun; 14(3):435-8. PubMed ID: 3114483.
    Abstract:
    Alveolar macrophages obtained by bronchoalveolar lavage (BAL) were evaluated by electron dispersive microanalysis (EDX) for the presence of elemental gold. EDX revealed gold in 90% (9/10) of patients with RA who were currently receiving chrysotherapy or who had discontinued chrysotherapy less than 24 months before BAL. All patients who had discontinued chrysotherapy more than 24 months before BAL (range: 3-14 years) were EDX negative (4/4), as were patients with RA who had never received gold therapy (5/5). Seven patients with RA (7/19) had clinical evidence of interstitial lung disease and 12 patients (12/19) had no interstitial lung disease. There was no correlation between chrysotherapy and the development of interstitial lung disease. These results demonstrate that gold is retained for prolonged periods in pulmonary tissue macrophages but do not identify any relationship between gold and chronic rheumatoid lung disease.
