Insights
Severe protein-loss in atopic dermatitis (SPLAD) in infants can be managed effectively. Topical corticosteroid use can be significantly reduced within three years with appropriate skin treatment, improving prognosis.
Area of Science:
- Pediatric Allergy and Immunology
- Dermatology
- Clinical Nutrition
Background:
- Severe protein-loss in atopic dermatitis (SPLAD) is a serious complication in early infancy.
- Understanding the long-term prognosis of SPLAD is crucial for effective management.
Purpose of the Study:
- To investigate the prognosis of infants diagnosed with severe protein-loss in atopic dermatitis (SPLAD).
- To evaluate the long-term outcomes of SPLAD management, including topical corticosteroid (TCS) use and dietary changes.
Main Methods:
- A single-center, retrospective observational study involving 61 children with SPLAD.
- Analysis of patient records from 2002 to 2017, focusing on clinical characteristics, laboratory results, and treatment outcomes up to three years.
- Assessment of topical corticosteroid (TCS) frequency and food intake status.
Main Results:
- All patients showed improvement in hypoproteinemia and electrolyte imbalances with AD treatment alone.
- Proactive therapy led to sustained remission in 77% (1 year), 92% (2 years), and 95% (3 years) of patients using TCS twice weekly or less.
- After three years, 39% of patients achieved remission without TCS, and 29% of those under one year at admission could tolerate egg, milk, or wheat.
- No patients required systemic therapies.
Conclusions:
- Appropriate skin treatment can significantly reduce topical corticosteroid (TCS) use in severe protein-loss in atopic dermatitis (SPLAD) cases.
- SPLAD demonstrates a favorable prognosis with effective management, allowing for reduced medication dependence and potential tolerance of common allergens.
Background:
Atopic dermatitis (AD) in early infancy can lead to severe protein-loss in atopic dermatitis (SPLAD). The aim of this study was to elucidate the prognosis of SPLAD.
Methods:
This was a single-center, retrospective, observational study based on medical records. Participants comprised 61 children with SPLAD hospitalized at the Allergy Center, National Center for Child Health and Development, from 2002 to 2017. We examined patient characteristics, blood test results, and prognoses up to 3 years, including frequency of topical corticosteroid-(TCS) use and food intake status.
Results:
All participants improved hypoproteinemia and electrolyte abnormalities with AD treatment alone, without intravenous fluids. We performed proactive therapy to maintain remission by gradually decreasing the frequency of TCS-use. After 1, 2, and 3 years, 77%, 92%, and 95%, respectively, remission was maintained by using TCS 2 days a week or less, whereas 39% did not require TCS after 3 years. No participants received systemic therapy, including systemic steroids, immunosuppressants, or biologics. We observed that 29% of infants younger than 1 year at admission had eliminated one or more egg, milk, or wheat component after 3 years.
Conclusions:
Even in patients with SPLAD, the most severe AD, TCS-use may be reduced to 2 days per week or less after 3 years with appropriate skin treatment.
