title: Effect of age and disease on two drug binding proteins: albumin and alpha-1- acid glycoprotein.
abstract: The influence of age and disease on serum albumin and alpha-1-acid glycoprotein was studied in 126 subjects (69 M, 57 F) presenting with tuberculosis and after recovery. Albumin concentration fell with age in both disease and healthy states, and alpha-1-acid glycoprotein concentration rose with age in the healthy state. Age-related differences were less marked in the disease state. During recovery from illness, serum albumin concentration rose and alpha-1-acid glycoprotein concentration fell. The mean concentration difference in the latter was lower in the older age groups. The clinical consequences of changes in binding protein concentrations as a result of ageing and disease need to be studied further for individual drugs.
