congenital analbuminemia: DISCUSSION (part 1)

Individuals with CAA undergo a series of compensatory mechanisms including an increase in alternative proteins, an increase in protein half-life and adjustments to the osmotic and hydrostatic pressure gradients. In the absence of serum albumin, hepatic cells compensate by increasing the biosynthesis of other plasma proteins, including а, в and у proteins. These compensatory proteins raise serum total protein levels and contribute to osmotic pressure and also assume some of the roles of albumin. For example, bilirubin will alternatively bind to high-density lipoproteins in the absence of albumin.If serum albumin levels are restored to their normal range, by albumin infusion, this compensatory up-regulation stops and compensatory protein levels return to normal. Studies have found that the half-life of infused albumin in individuals with CAA is prolonged by up to four-times, with the rate of degradation slowing as serum albumin levels decrease. The osmotic pressure gradient is maintained by the compensatory increase in plasma proteins, as well as by increased transcapillary fluid filtration and lymph drainage, and the reduced hydrostatic pressure gradient is achieved by lowered capillary blood pressure and increased interstitial hydrostatic pressures.

Existing literature provides little information on the effect of fetal CAA in pregnancy, with reports including SGA, placental edema or infarction, and frequent miscarriage.
