Bleeding Disorders in Children: Types, Symptoms, Diagnosis and Treatment

Bleeding Disorders in Children

Our body has several essential mechanisms to prevent excessive bleeding when we’re injured. However, some children are born with a disorder that affects their ability to clot properly, leading to mild or severe bleeding after injuries or surgery.

Types of Bleeding Disorders in Children

Bleeding disorders occur in many different forms. A normal coagulation (blood clotting) process comprises up to 20 distinct plasma proteins, often known as clotting factors. A patient with an imbalanced clotting system may bleed too easily, or form improper clots, depending on the severity of the problem

Types 

Hemophilia

Von Willebrand disease

Platelet function disorders

Hypofibrinogenemia and dysfibrinogenemia

Certain clotting proteins are absent or insufficient in hereditary bleeding diseases. Hemophilia A (factor VIII deficiency), hemophilia B (factor IX deficiency), and von Willebrand disease are the three most prevalent inherited bleeding / coagulation disorders.

Hemophilia

haemophilia

Hemophilia is a disorder, in which there is inability of the body to coagulate blood. In hemophilia, the body does not produce enough of one of the clotting factors. Because of this, a person with hemophilia may experience prolonged internal bleeding in their muscles and joints after an injury or, even unprovoked. In severe cases, bleeding into the brain parenchyma is also observed.

When clotting factor VIII levels are low or nonexistent, hemophilia A is identified. Christmas disease, another name for hemophilia B, is less prevalent and is brought on by low or missing clotting factor IX levels. Hemophilia can be classified as mild, moderate or severe based on the blood’s level of factor activity. 

Symptoms 

Hemophilia symptoms

Hematomas are large bruises brought on by bleeding beneath the skin.

Bleeding into the muscles or joints, either naturally occurring or as a result of an accident, which results in stiffness and edema.

Bleeding in the gums and mouth after surgery or dental procedures

Bleeding after receiving a injection or vaccine

Blood in the feces or urine

Difficult-to-stop nosebleeds.     

Life threatening situations like bleeding into the brain.

Von Willebrand Disease

VWD

A genetic bleeding disorder called von Willebrand disease (VWD) is brought on by a malfunction in the von Willebrand factor (VWF), a protein that helps in blood coagulation. This protein plays a crucial role in the early stages of blood clot formation, helping to stop bleeding after an injury or surgery. Acting like adhesive, VWF helps platelets stick together to form a clot. It is one of several clotting proteins that must work in harmony to prevent excessive bleeding.

Symptoms

Frequent or prolonged nosebleeds

Prolonged or heavy menstrual bleeding in girls; 

Heavy or prolonged bleeding from the gums during dental procedures such as teeth cleaning and extractions etc.

Excess bleeding during or soon after surgery

Frequent or prolonged large bruises from minor bumps or injuries

Excessive bleeding from minor cuts

Thrombocytopenia

Thrombocytopenia

There are a number of factors that can lead to thrombocytopenia in children, but the most common ones are infections, particularly viral infections, and immune system destruction of platelets (also known as immune thrombocytopenia or ITP). Children with thrombocytopenia may also have reduced amounts of other blood cell types, including red and white blood cells, depending on the cause.

Platelet Function Disorders

Platelets are blood cells that help in blood clotting in order to stop bleeding. Children who have a platelet function problem are more likely to bleed as the initial step of platelet plug formation is improper. Genetic etiology could be the underlying reason of platelet function problems in children.

Symptoms 
Platelet function disorders

Nosebleeds

Purpura (a purplish discoloration of the skin caused by blood leaking beneath the surface, often without any apparent injury)

Petechiae (small red spots on the skin due to tiny blood vessels bleeding)

Bleeding in the mouth 

 Presence of blood in vomit, urine, or stool

Bleeding in the head

Hypofibrinogenemia and dysfibrinogenemia

A less severe form of fibrinogen deficit is called hypofibrinogenemia, which occurs when there is fibrinogen in the blood but not enough of it for appropriate coagulation to take place. 

An uncommon clotting condition called dysfibrinogenemia is brought on by an aberrant or reduced quantity of fibrinogen.

Diagnosis of bleeding disorders

Complete Blood Count (CBC): This test measures red blood cells, white blood cells, and platelets, all of which play essential roles in blood clotting.

Clotting Time Tests: These include Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT), used to evaluate how quickly blood clots form.
Bleeding Time and Clotting time : They are helpful to know platelet and clotting factor defects

Clotting Factor Levels: Also known as factor activity levels, this test assesses the amount of each clotting factor in the blood.

Genetic Testing: A DNA analysis to detect any abnormalities in the genes related to blood clotting.

Treatment of bleeding disorders

The conventional approach to treating haemophilia A and B focusses on replacing the missing clotting factor.

Newer haemophilia therapies are now available, such as longer-acting intravenous factor replacements that prevent bleeding with fewer doses and other non-replacement therapies such as usage of monoclonal antibodies.

Most children born with mild vWD will have minor bleeding issues, so regular medications are often not necessary. However, adolescents and adults with severe vWD disease,who menstruate may have heavy periods that require hormone control along with factor therapy.

The medications used to prevent or treat excess bleeding from surgeries, dental extractions, or injuries in children with vWD vary depending on the type of vWD and the specific symptoms.

Conclusion

Bleeding disorders in children require timely diagnosis and care to manage symptoms and prevent complications. Understanding the condition, its types, and available treatments is key to ensuring the best outcomes. With early intervention and expert guidance of Pediatric hematologist children with bleeding disorders can lead healthy, active lives.

FAQs for Bleeding Disorders in Children: Types, Symptoms, Diagnosis and Treatment

Bleeding disorders are conditions where a child’s blood doesn’t clot properly, leading to prolonged or excessive bleeding after an injury or surgery.

Ensure the child gets adequate sleep for their age group.

Promote regular physical activity to keep their immune system robust.

The common types include hemophilia, von Willebrand disease, platelet function disorders, and conditions like hypofibrinogenemia and dysfibrinogenemia.

Most bleeding disorders are genetic and inherited, though some may result from other medical conditions, infections, or immune system issues.

Symptoms include frequent nosebleeds, excessive bruising, prolonged bleeding after injuries or dental procedures, and in severe cases, blood in the stool or urine.

Hemophilia is caused by a deficiency of specific clotting factors (factor VIII or IX), while von Willebrand disease is due to a defect or deficiency in the von Willebrand factor, which helps platelets stick together.

Diagnosis involves tests like a Complete Blood Count (CBC), clotting time tests (PT, aPTT), clotting factor levels, and genetic testing to identify specific abnormalities.

Treatments may include clotting factor replacement, medications like monoclonal antibodies, hormone therapy for certain cases, and specialized care during surgeries or injuries.

Yes, with timely diagnosis, proper management, and expert care, children with bleeding disorders can lead healthy and active lives.

Pack non-perishable snacks like crackers, dried fruits, or protein bars, and make sure to carry enough baby food and formula for at least 24 hours in case of delays.

While most bleeding disorders are not curable, they can be effectively managed with modern treatments, allowing children to minimize complications.

Consult a doctor if your child has frequent or severe nosebleeds, unusual bruising, prolonged bleeding after injuries, or blood in their stool, urine, or vomit.
