Sequential changes in the concentration of specific serum proteins during typhoid fever infection in man.
An automated immunoprecipitin system has been utilized to quantitate the concentration of 10 specific proteins in the plasma of man.  Values obtained by this technique are in agreement with the published concentrations for these specific plasma proteins.  This technique was utilized to determine the sequential change s in 10 individual plasma proteins of volunteers exposed to Salmonella typhi.  In those volunteers who developed typical typhoid fever, plasma concentrations of the acute phase proteins, alpha1-acid glycoprotein, alpha1-antitrypsin, and haptoglobin, as well as C3 complement were significantly increased with the onset of febrile illness.  In contrast, the concentration of plasma albumin and tranferrin were depressed while plasma IgM became elevated during early convalescence from this infection.  No significant changes were observed in the plasma concentrations of alpha2-macroglobulin, IgG, or IgA.  In the exposed volunteers who did not become ill, the only significant change was a brief depression of alpha1-antitrypsin.  During typhoid fever the patterns of change for individual plasma acute-phase globulins were different from those reported for patients with hepatitis, myocaridal infarction, or surgery.
