What is Polycythaemia Vera Follow-Up?

Polycythaemia vera (PV) is a chronic myeloproliferative neoplasm caused by JAK2 V617F or exon 12 mutations and characterised by erythrocytosis, leukocytosis and thrombocytosis.

Lifelong follow-up aims to maintain haematocrit below 45%, reduce thrombotic risk with low-dose aspirin and apply hydroxyurea or ruxolitinib cytoreduction in high-risk patients.

Symptoms

Aquagenic pruritus (worse after a hot shower)
Headache, dizziness, blurred vision
Erythromelalgia (burning pain in extremities)
Splenomegaly (early satiety)
Thrombosis (DVT, cerebrovascular event)

Risk Factors

Age >60 (high-risk classification)
Previous thrombosis history
JAK2 V617F allele burden >50%
Cardiovascular risk factors (HT, DM, smoking)
Leukocytosis (WBC >11,000)

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Symptoms suggesting thrombosis (sudden swelling, neurological deficit)
  • Headache or visual disturbance with HCT >45%
  • Splenomegaly progression or transformation symptoms (fatigue, weight loss)
  • Suspected hydroxyurea resistance/intolerance

Treatment Methods

01
Phlebotomy (target HCT <45% in men and women)
02
Low-dose aspirin (81-100 mg/day)
03
Hydroxyurea (first-line cytoreduction in high-risk patients)
04
Ruxolitinib (in hydroxyurea-resistant or intolerant cases)
05
Pegylated interferon alpha (option in young patients and pregnancy)
06
JAK2 allele burden monitoring (every 6-12 months)
07
Annual bone marrow biopsy (in suspected myelofibrotic transformation)

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
