What is Transfusion Reactions and Management?

Transfusion reactions are adverse events that occur during or after the administration of blood and blood products. Acute reactions appear during transfusion or within 24 hours, while delayed reactions develop days to weeks later.

Acute hemolytic transfusion reaction is the most serious complication and is caused by ABO-incompatible transfusion. Transfusion-related acute lung injury (TRALI) is a noncardiogenic pulmonary edema mediated by donor antibodies. Febrile non-hemolytic and allergic reactions are the most common complications.

Transfusion safety relies on patient identity verification, crossmatch compatibility, appropriate storage, and continuous vital sign monitoring. When a reaction develops, the transfusion must be stopped immediately, the blood bank notified, and supportive treatment started promptly.

Symptoms

Fever and chills (febrile reaction)

Urticaria, itching, and rash (allergic reaction)

Back pain, dark urine, and hypotension (hemolytic reaction)

Dyspnea and hypoxia (TRALI)

Anaphylaxis (severe allergic reaction)

Volume overload (TACO)

Risk Factors

Multiple prior transfusions

Pregnancy history with potential alloimmunization

IgA deficiency (anaphylaxis risk)

Heart failure (TACO risk)

Immunocompromised patients (CMV, TA-GVHD risk)

When to See a Doctor?

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

Fever, chills, or rash develop during transfusion
Dyspnea or hypotension occur
Dark urine and back pain begin

Treatment Methods

Stop the transfusion when a reaction develops

Hemolytic reaction: IV hydration and diuretics

Allergic reaction: antihistamines plus epinephrine for anaphylaxis

TRALI: oxygen support and mechanical ventilation

TACO: diuretics and upright positioning

Notify the blood bank and send samples for investigation

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.
