title: Adenosine deaminase activity in normal pregnancy and pregnancy associated disorders.
abstract: Adenosine deaminase (ADA) is an enzyme of purine salvage pathway and has two important isoenzymes ADA1 and ADA2. The activity of ADA has been changed in diseases characterized by altered cell-mediated immunity. It was observed that total serum ADA activity was decreased during normal pregnancy compared with non-pregnant women. However, total serum ADA activity and serum ADA2 activity was increased in hyperemesis gravidarum and pre-eclampsia in pregnant women. Less information is available regarding role of ADA in abortions (recurrent and missed) and anembryonic pregnancies. Here, we review the activity of ADA and its isoenzymes. Despite these findings, it will be interesting to know whether activity of ADA will be same if ADA is estimated throughout the pregnancy and in pregnancy related complications from early first trimester to third trimester, as all studies until now were carried out at a particular stage of pregnancy.
