[Circadian rhythms of the so-called inflammation proteins in healthy subjects]

Circadian rhythms for the factors listed below were investigated in 14 subjects hospitalized in apparently good health: total proteins, albumin, pre-albumin, alpha-1-antitrypsin, orosomucoid, ceruloplasmin, C3, C-reactive protein, haptoglobin and transferrin. Seven venous blood samples were taken from each subject over a 24 hour period. A circadian rhythm was detected for the total proteins, prealbumin, alpha-1-antitrypsin, orosomucoid, ceruloplasmin and transferrin. The acrophases occurred at about 12 hour intervals and the authors research group are already investigating these rhythms for the "inflammation proteins" and the transport proteins in cancer and inflammatory processes.
