• So – answers?
– Phlebotomy goal should be a hematocrit of less than 45%
– In women, generally aim for even lower than that, 42-43%
• Frequency varies – but as often as needed
• Sometimes medication also needed, but you have to give phlebotomy a chance

• 57 yo man with Essential
Thrombocythemia
– Incidentally discovered two years ago
– No symptoms, no history of blood clots
– Platelet count of 1,380 k/uL
– Now with found to occult + stools
– Colonscopy normal, but stomach ulcers noted on endoscopy
We Practice What We Teach Milwaukee
• Not as common as clotting problems
• Often manifest with
– Nosebleeds
– Gum bleeding
– Menorrhagia
– Less likely to be deep tissue bleeding
• Rarely can be life threatening
• Risk increases with
Platelets>1,000,000/uL

• What can we do about his nose bleeds?
– Normalization of platelet count
– Medication vigilance combos in particular
• Anagrilide + Aspirin
• Plavix or Aspirin + heparin products
– Predictable bleeding
• i.e. interventions to prevent menorrhagia
– Special care in individuals with gastric ulcers or esophageal varices

• 67 years old with PV
• TIA in her late 50s
• Treatment: HU and aspirin
• Recently diagnosed with small left-sided breast cancer, has opted for mastectomy
• What are my surgical risks?
• Surgery and VTE
• Increased risk for patients with MPN
• Likely due to differences in the
– Blood vessels
– Platelets
– Clotting factors?

• Does the disease occur more frequently in one sex vs. the other?
– Diagnostic bias?
– Due to exposure?
– Due to genetic predisposition?
• Does the disease behave differently in one sex vs the other?
– Modulated hormones? Gender-based lifestyle differences?
– Interactions that we don’t understand?

• 37 yo woman with a history of thrombosis in her right calf while on birth control
• Found to have JAK2 mutation and a slightly elevated platelet count
• She asks you:

• ET – most common MPN in fertile women
• Hormonal contraception +
ET = hypercoaguable state
• Pregnancy + ET = hypercoaguable state
• Thrombosis -- #1 cause of maternal death
We Practice What We Teach Milwaukee
• Contraception
– Combination hormones
>progesterone only OCPs
– General population have a 3–6-fold increased risk of venous thrombosis with OCPs
• One retrospective study of >300 patients. Subset on OCPs
– ET + OCPs = 23% VTE
– ET no OCPs = 7% VTE
We Practice What We Teach Milwaukee

• Pregnancy outcomes likely impacted
– Live birth rate 50-70%
– First trimester loss 10-20%
– Late pregnancy loss 10%
– Increased rates of placental abruption, intrauterine growth restriction
• Can we change those outcomes?
We Practice What We Teach Milwaukee
• Risk Assessment
– Prior VTE or arterial clot
– Prior hemorrhage
– Prior pregnancy complication
– Diabetes or Hypertension requiring treatment
– Platelet count of >1500 X 10 9 before or during pregnancy

• Multidisciplinary approach
• Discussion of teratogenic drugs
• Therapeutic options
– Aspirin
– LMWH
– Cytoreductive therapy
• Delivery and post-partum plan
• Breastfeeding information
We Practice What We Teach Milwaukee
Antiplatelet agents reduce risk of VTE in ET patients
Pregnancy is thrombotic
Aspirin is likely safe in pregnancy (APLA pts)
• Generally
– Continue low-dose aspirin
– Monitor platelet or Hct
• Keep HCT under 45%
• Consider venesection if necessary
– Increased plasma volume of pregnancy means no set targets
We Practice What We Teach Milwaukee
• Remove possible teratogeneic drugs
– Taper off hydrea or anagrilide 3-6 months prior to conception
– Hydrea likely contraindicated, men and women
– Anagrilide crosses the placenta
• Cytoreduction
– Interferon-alpha -- Case reports indicating likely safe
• Prevent Clotting
– LMWH
– Prophylactic or, in some cases, therapeutic doses
We Practice What We Teach Milwaukee
• Some symptoms can be addressed with a palliative approach
• Some require that the disease be treated
• Target Hgn, PV
• Preventing Bleeding
• Undergoing Surgery
• Gender-specific issues: Contraception, Fertility and Pregnancy
• Modifying risk – lifelong effort for all patients
– Cholesterol, Blood pressure, SMOKING
