What is Immune Cytopenias in Hematology?

Immune cytopenias are disorders in which the body produces autoantibodies against its own blood cells. The result may be immune thrombocytopenia (ITP), autoimmune hemolytic anemia (AIHA, warm or cold type), autoimmune neutropenia, or several lineages affected simultaneously (Evans syndrome).

These conditions can be primary (idiopathic) or secondary to lymphoproliferative disease, connective tissue disease such as lupus, common variable immunodeficiency, infection, or drugs. A careful history, peripheral smear, and targeted serology distinguish primary disease from a secondary cause that requires treating the underlying problem.

Modern treatment is shaped by mechanism. ITP responds to corticosteroids, IVIG, thrombopoietin receptor agonists (eltrombopag, romiplostim), and rituximab. Warm AIHA is treated with steroids and rituximab; cold agglutinin disease responds to sutimlimab or rituximab-bendamustine. Splenectomy is reserved for refractory cases.

Symptoms

Easy bruising, petechiae, mucosal bleeding (ITP)
Fatigue, jaundice, dark urine (hemolytic anemia)
Recurrent infections (autoimmune neutropenia)
Pallor and exertional dyspnea
Splenomegaly in some patients
Acrocyanosis on cold exposure (cold agglutinin disease)

Risk Factors

Underlying lymphoma or chronic lymphocytic leukemia
Systemic lupus erythematosus and other autoimmune disease
Common variable immunodeficiency
Recent viral infection (EBV, CMV, parvovirus B19)
Certain drugs (heparin, beta-lactams, methyldopa)

When to See a Doctor?

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

  • Spontaneous bruising or mucosal bleeding
  • Sudden pallor with dark urine
  • Unexplained recurrent infections
  • Persistent low blood counts on routine testing

Treatment Methods

01
Corticosteroids as first-line for ITP and warm AIHA
02
Intravenous immunoglobulin for rapid platelet rise
03
Rituximab for refractory or relapsed disease
04
Thrombopoietin receptor agonists (eltrombopag, romiplostim) in ITP
05
Sutimlimab for cold agglutinin disease
06
Treatment of any underlying secondary cause
07
Vaccination and infection prevention before splenectomy

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.
