Neonatal erythroderma-autoinflammation-inflammatory bowel disease syndrome

What it is

From: Orphanet

Neonatal inflammatory skin and bowel disease is a rare, life-threatening, autoinflammatory syndrome with immune deficiency disorder characterized by early-onset, life-long inflammation, affecting the skin and bowel, associated with recurrent infections. Patients present perioral and perianal psoriasiform erythema and papular eruption with pustules, failure to thrive associated with chronic malabsorptive diarrhea, intercurrent gastrointestinal infections and feeding troubles, as well as absent, short or broken hair and trichomegaly. Recurrent cutaneous and pulmonary infections lead to recurrent blepharitis, otitis externa and bronchiolitis.

Reported clinical features and what the terms mean

The following findings are associated with this condition in Orphanet. They are not a checklist for diagnosing yourself, and they do not all occur in every affected person. Some are examination, imaging or laboratory findings that cannot be recognised at home.

The frequency labels describe how often a finding was reported among people with the condition in the source. They do not give the chance that a person with that symptom has the condition. Definitions below reproduce HPO terminology; they explain the term, not the likely severity in an individual.

Anal fissure · Frequent (79-30%)

A small tear in the thin, moist tissue (mucosa) that lines the anus. It appears as a crack or slit in the mucous membrane of the anus.

Blepharitis · Frequent (79-30%)

Inflammation of the eyelids.

Bloody diarrhea · Frequent (79-30%)

Passage of many stools containing blood.

Chapped lip · Frequent (79-30%)

Cracking, fissuring, and peeling of the skin of the lips.

Chronic monilial nail infection · Frequent (79-30%)

Chronic infection of the nails by Candida species.

Erythema · Frequent (79-30%)

Redness of the skin, caused by hyperemia of the capillaries in the lower layers of the skin.

Generalized abnormality of skin · Frequent (79-30%)

An abnormality of the skin that is not localized to any one particular region.

Horizontal eyebrow · Frequent (79-30%)

An eyebrow that extends straight across the brow, without curve.

Onychogryphosis · Frequent (79-30%)

Onychogryphosis is a disorder of nail plate growth that is clinically characterized by an opaque, yellow-brown thickening of the nail plate with associated gross hyperkeratosis, elongation, and increased curvature.

Otitis externa · Frequent (79-30%)

Inflammation or infection of the external auditory canal (EAC), the auricle, or both.

Perianal rash · Frequent (79-30%)

The presence of a rash (change of color and texture) of the perianal skin.

Psoriasiform dermatitis · Frequent (79-30%)

A skin abnormality characterized by redness and irritation, with thick, red skin that displays flaky, silver-white patches (scales).

Pustule · Frequent (79-30%)

A small elevation of the skin containing cloudy or purulent material usually consisting of necrotic inflammatory cells.

Recurrent bacterial skin infections · Frequent (79-30%)

Increased susceptibility to bacterial infections of the skin, as manifested by recurrent episodes of infectious dermatitis.

Other findings in the same source

From: Orphanet

Additional reported features include Recurrent gastroenteritis (Frequent (79-30%)); Scaling skin (Frequent (79-30%)); Slow-growing scalp hair (Frequent (79-30%)); Left ventricular hypertrophy (Occasional (29-5%)). This is a selected summary, not a complete description of the condition.

When it may begin

From: Orphanet

Infancy; Neonatal

Inheritance in the source

From: Orphanet

Autosomal recessive

Frequency and the population described

From: Orphanet

Reported case(s): 3.0; Worldwide. This is a published case count, not prevalence. Point prevalence: <1 / 1 000 000; Worldwide; Class only.

Understanding the inheritance label

From: MedlinePlus Genetics

An autosomal recessive pattern usually involves disease-causing changes in both copies of a gene. Parents may each carry one altered copy without having the condition themselves. A genetic counsellor can explain carrier testing and reproductive implications using the actual laboratory findings, rather than the condition name alone.

Which doctor should you see?

The suggested department for discussing Neonatal erythroderma-autoinflammation-inflammatory bowel disease syndrome is Gastroenterology, with a gastroenterologist as the relevant type of clinician. General physician / Family Medicine; paediatrician for children. Referral depends on symptoms.

Additional services that may be relevant, depending on the findings, include: Clinical Genetics.

This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.

How to prepare for an assessment

Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.

Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.

• Which digestive symptoms or nutritional changes matter most?
• What question would an endoscopy, scan or laboratory test answer if one is proposed?
• How should persistent pain, bleeding or difficulty eating be followed up?

Treatment discussions and follow-up

The material gathered for this draft does not provide a complete condition-specific treatment pathway for Neonatal erythroderma-autoinflammation-inflammatory bowel disease syndrome. That gap does not mean that treatment is unavailable. A clinician needs to establish the diagnosis and review current guidance before recommending medicines, procedures, rehabilitation or other support.

Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.

The collected references do not establish a complete prevention or long-term outlook section for this entry. Missing information should not be interpreted as proof that prevention is impossible or that a particular outcome is inevitable. Ask what is known for the exact subtype, stage and personal circumstances, and which uncertainties remain.

When to seek emergency help

Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
