Where/why a 22 y/o may present with heavy menses (HMB)

Decreased platelet

number and/or function

Decreased or dysfunctional von Willebrand factor

1.Decreased fibrin generation from the initiation of tissue factor that combines with VIIa→activates X →Xa activates prothrombin → thrombin then generates fibrin clot through cleavage of fibrinogen 2. Decreased fibrin propogation via FXI, FIX and FVIII 3. Decreased fibrin cross-linking d/t FXIII deficiency

Increased plasmin generation due to decreased anti-plasmin

or PAI

In ED with heavy period & blood blisters

in mouth

Dx- ITP

Heavy menses past 2 periods with severe cramps on Motrin 800 qid

Dx- Drug-induced platelet dysfunction

HMB since menarche and freq. epistaxis & bruising; mother same sx

Dx - Inherited Platelet Function Disorder (e.g., dense granule deficiency)

HMB since menarche, epistaxis and easy bruising;

mother same sx

Dx - Von Willebrands,

Type 1

HMB since menarche, history of bleeding at time of umbilical cord separation, easy bruising and epistaxis, history of knee hemearthroses when she fell off skateboard age 11 , mother asymptomatic

Dx - Severe FVII deficiency or could also be any severe rare bleeding disorder like Fibrinogen (FI) deficiency or Prothrombin (FII) deficiency or Factor V deficiency or Factor VII deficiency or FVIII or FIX carrier who is lyonized or Factor XI deficiency or FXIII deficiency

HMB since menarche with easy brusing; mother asymptomatic Dx- Inherited anti-plasmin or

plasminogen activator inhibitor HMB progressively worse past 4-6 cycles, no epistaxis or easy

bruising or family history

Dx - idiopathic HMB- in up to

50% of cases of HMB!

Hemosta7c Therapy Beyond Tranexamic Acid DDAVP induces Endothelial cell (EC) via cAMP mediated Weibel- Palade Body secretion increasing membrane- bound and circulating VWF as well as FVIII

DDAVP also induces platelet release and membrane presentation of P-selectin which Mediates platelet rolling on ECs under high shear conditions through PSGL-1/P-selectin Interaction

DDAVP increases EC adhesiveness for platelets and platelet adhesion to collagen probably via VWF P.J.SvenssonBloodReviews28(2014)95–102
