Amyloidosis was produced in mice by repeated subcutaneous injections of 0.5-or 0.005-milligram amounts of Escherichia coli endotoxin. Of the two strains of mice examined, amyloidosis was induced more readily in one than in the other. The ability of endotoxin to induce amyloidosis lends support to the view that stimulation of reticuloendothelial cells leads to amyloid formation.

We performed human lymphocyte alloantigen determinations in patients with psoriatic arthritis (PsPA) who were clinically classified into arthritic subtypes and disease severity. The total PsPA group demonstrated elevations of HLA-BW38, CW6, DR4 when compared with controls (p less than 0.001). Severe arthritics have increased DR4 frequency when compared with less severe arthritics (p less than 0.02). Those with mild disease have increased A3, B7 frequency which was absent in patients with moderate or severe arthritis. Rheumatoid-like PsPA patients have increased DR4, B40 frequencies; those with spondylitis, B27, CW1. PsPA is associated with many genes in the major histocompatibility complex. Distinct groups of patients with PsPA as determined by type and severity are identifiable by the presence of specific human lymphocyte antigens.

A patient with symptoms of respiratory insufficiency was found to have interstitial lung disease, polymyositis, and breast carcinoma. Signs and symptoms of pulmonary disease rapidly reversed with prednisone and cytotoxic drug therapy. This is the 1st such case reported and stresses the need for careful evaluation of similar patients.
