CHAPLE syndrome (CD55 Deficiency with Hyperactivation of Complement, Angiopathic Thrombosis, and Protein-Losing Enteropathy) is a rare inherited genetic disorder caused by mutations in the CD55 gene. The condition disrupts the regulation of the complement system, leading to excessive immune activation, recurrent infections, protein loss from the intestines, blood clotting problems, and poor growth. Early diagnosis and appropriate treatment are essential to reduce complications and improve long-term health outcomes.

What are the Types of Chaple Syndrome?

CHAPLE syndrome is a single genetic disorder rather than a condition with multiple recognized clinical types. However, it can present with varying manifestations depending on disease severity.

Classical CHAPLE Syndrome: Characterized by protein-losing enteropathy, recurrent infections, edema, and complement system overactivation.
Severe Early-Onset CHAPLE Syndrome: Presents during infancy or early childhood with severe gastrointestinal symptoms, poor growth, recurrent infections, and thrombotic complications.
Milder CHAPLE Syndrome: Some individuals develop less severe symptoms later in childhood or adulthood with variable disease progression.

What are the Symptoms of Chaple Syndrome?

The symptoms of CHAPLE syndrome primarily affect the digestive, immune, and circulatory systems.

Recurrent Bacterial Infections
Chronic Diarrhea
Protein-Losing Enteropathy
Swelling (Edema) of the Face, Legs, or Abdomen
Poor Growth or Failure to Thrive
Abdominal Pain
Fatigue and Weakness
Blood Clot Formation (Thrombosis)

What are the Causes of Chaple Syndrome?

CHAPLE syndrome is caused by inherited mutations in the CD55 gene, resulting in uncontrolled activation of the complement immune pathway.

Inherited Mutations in the CD55 Gene
Autosomal Recessive Genetic Inheritance
Excessive Activation of the Complement System

When to See a Doctor for Chaple Syndrome?

If your child experiences recurrent severe bacterial infections, persistent swelling, unexplained inflammation, delayed growth, or signs of immune system dysfunction, consult a Pediatrician. Early diagnosis and treatment can help reduce infections, prevent complications, and improve your child's overall health and quality of life.

If your child has frequent or recurrent bacterial infections.
If there is persistent swelling of the face, limbs, or other parts of the body.
If your child develops unexplained fever, fatigue, or poor growth.
If infections are severe, difficult to treat, or keep returning despite treatment.
If there is a family history of CHAPLE syndrome or inherited immune disorders.
If your child experiences abdominal pain, chronic diarrhea, or signs of protein loss.
If blood tests show abnormalities related to the immune or complement system.
If your child's symptoms persist or worsen, consult a Pediatrician for a comprehensive evaluation, diagnostic testing, and a personalized treatment plan.

How is Chaple Syndrome Diagnosed?

Diagnosis is based on clinical findings, laboratory investigations, and genetic confirmation.

Genetic Testing for CD55 Gene Mutations
Physical Examination and Medical History
Blood Tests to Assess Complement System Activity
Protein Level Measurements and Stool Tests for Protein Loss
Imaging Studies When Required

How is Chaple Syndrome Treated?

Treatment focuses on controlling complement activation, managing symptoms, and preventing complications.

Complement Inhibitor Therapy: Medications such as eculizumab may help control excessive complement activation.
Supportive Medical Care: Treats infections, edema, and nutritional deficiencies.
Nutritional Therapy: High-protein diets and nutritional supplementation help replace protein losses.
Physical Therapy: Supports mobility and overall physical health when needed.
Regular Monitoring: Ongoing follow-up helps detect complications early and optimize treatment.
