Flashcard 563: Which **complement protein** level is characteristically **decreased** in **C1 esterase inhibitor deficiency**?
_____
Answer: C4
Extra: C1 esterase inhibitor deficiency leads to unregulated activation of the classical pathway, resulting in excessive consumption of **C4** (and C2).
The lack of kallikrein inhibition leads to increased **bradykinin**, which is the primary mediator of the associated angioedema.
Note: **C3** levels are typically **normal** in this condition, making the generation of C3a/C5a less significant than C4 consumption and bradykinin production.

Answer: normal
Extra: Bleeding in scurvy is characterized by petechiae, ecchymoses, and gingival bleeding. Because the defect is structural (collagen hydroxylation) rather than enzymatic (clotting factors), laboratory coagulation studies (PT/PTT) remain normal.
