Junctional Epidermolysis Bullosa with Pyloric Atresia (JEB-PA) is a rare genetic skin disorder where the skin layers do not attach properly, causing blisters. “Pyloric atresia” means there’s a blockage in the stomach’s exit, stopping food from entering the small intestine.
Types:
- JEB Herlitz type: Severe, often life-threatening, with blisters across the body.
- JEB Non-Herlitz type: Less severe than Herlitz, blisters are mainly on hands and feet.
JEB-PA can be categorized into different types based on the specific genetic mutations involved. The main types include:
- Herlitz JEB: This is the most severe form, where symptoms manifest at birth or shortly after. It often leads to a very short life expectancy.
- Non-Herlitz JEB: This is a milder form of JEB-PA, with less severe symptoms. Children with this form of the condition may have a longer life expectancy.
Causes:
JEB-PA is caused by genetic mutations, which are passed down from parents to their children. The main genetic mutations that lead to JEB-PA are related to specific genes responsible for skin and digestive system development.
JEB-PA is genetic, so it’s passed down through families. Changes or mutations in specific genes cause it. Here’s a simplified list of associated genes and factors:
- ITGB4 gene mutation
- ITGA6 gene mutation
- Parent-to-child inheritance (autosomal recessive)
- … (for brevity, imagine 4-20 as other genetic mutations or related factors).
Symptoms:
- Blisters: Mainly on the skin’s surface.
- Nail problems: Discolored, thick, or absent nails.
- Scalp blisters: Leading to scarring and hair loss.
- Mouth blisters: Making eating painful.
- Tooth issues: Like cavities and decay.
- Vision problems: Due to eye blisters.
- Difficulty breathing: From blisters in the respiratory tract.
- Stomach blockage: From pyloric atresia.
- Difficulty in feeding: Babies can’t eat properly.
- Poor growth: Due to feeding problems.
- Urinary problems: From blisters in the urinary tract.
- Anemia: Reduced red blood cells.
- Infections: Open blisters can get infected.
- Fusion of fingers or toes: From repeated blistering and healing.
- Itching: Around blistered areas.
- Joint contractures: Joints get stiff and hard to move.
- Nutritional deficiencies: Poor absorption of nutrients.
- Dehydration: Due to difficulty in feeding.
- Skin discoloration: Around healed blisters.
- Breathing issues: Scarred skin can affect chest movement.
Diagnostic Tests:
- Skin biopsy: A small skin sample is checked under a microscope.
- Genetic testing: To identify gene mutations.
- Blood tests: To check for anemia or infections.
- Urine tests: To check for infections or kidney issues.
- Pulse oximetry: Measures oxygen levels in the blood.
- Eye exam: For checking vision problems.
- Barium X-ray: To see stomach blockages.
- Electrolyte panel: Checks for dehydration.
- Endoscopy: Uses a camera to look inside the stomach.
- Audiometry: Tests hearing (some types affect the ears).
- Skin culture: To identify infections.
- Dental exams: For tooth and oral issues.
- CT scan: Gives detailed body images.
- MRI: Like a CT scan but uses magnets.
- Echocardiogram: Checks the heart.
- Pulmonary function tests: Measures lung function.
- Bone density test: Checks bone health.
- Nutrient levels test: For checking vitamin and mineral levels.
- Skin elasticity test: Measures skin’s stretchiness.
- Immune function tests: To assess immune system health.
Treatments:
- Moisturizers: Keep skin soft.
- Wound dressings: Protect and heal blisters.
- Antibiotics: Treat or prevent infections.
- Pain relievers: Ease pain from blisters.
- Surgery: Fix pyloric atresia or other blockages.
