Amino acid composition of amniotic fluid in intrahepatic cholestasis of pregnancy, pre-eclampsia and rhesus incompatibility.
The levels of free amino acids in amniotic fluid were determined in twenty patients with normal pregnancy, five with intrahepatic cholestasis of pregnancy, twelve with pre-eclampsia, and four with rhesus incompatibility. In pre-eclampsia there was no significant change in the amino acid composition of the amniotic fluid. In recurrent intrahepatic cholestasis the concentration of 15 out of the 22 amino acids studied was significantly higher than normal and the mean concentration of 4 others was more than 20 per cent above normal without this being statistically significant. In rhesus incompatibility there was a significant decrease in the concentration of 13 amino acids, and a decrease of more than 20 per cent in the mean concentration of 5 others.
