Linear IgA disease can cause severe conjunctivitis and corneal perforation. Early diagnosis and multidisciplinary care are crucial for managing this rare autoimmune condition.
Area of Science:
- Ophthalmology
- Dermatology
- Immunology
Background:
- Linear IgA disease is a rare autoimmune blistering disease.
- It can manifest with ocular symptoms, including chronic cicatrizing conjunctivitis.
Observation:
- A 65-year-old woman presented with rapidly progressive cicatrizing conjunctivitis and corneal perforation.
- She had a history of undiagnosed gingivitis, palatal ulceration, and vitamin C deficiency.
- Conjunctival biopsy revealed linear IgA deposits along the epithelial basement membrane.
Findings:
- The patient was diagnosed with linear IgA disease.
- Corneal perforation was successfully treated with a conjunctival pediculate flap.
- Systemic prednisolone and cyclophosphamide were required to control inflammation, despite significant side effects.
Implications:
- Linear IgA disease necessitates ophthalmological awareness due to its potential for severe ocular complications.
- Physicians should consider linear IgA disease in patients with cicatrizing conjunctivitis, especially with concurrent mucosal or skin involvement.
- Multidisciplinary management is essential for optimizing patient outcomes in complex cases.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
