Standard Treatment Guidelines and Essential Medicines List for South Africa, Hospital Level, Adults 2019 Edition
L20.0/L20.8-9
DESCRIPTION
Eczema is a pruritic, inflammatory skin condition characterised by vesicles, weeping, and crusting in the acute phase; and thickened, scaly skin with increased skin markings known as lichenification in the chronic phase.
Assessing severity
1% of body surface is equal to the size of one hand (including the fingers) of the patient.
Mild
- Less than 5% body surface involved.
- No acute changes.
- No significant impact on quality of life.
Moderate
- 5-30% body surface involved.
- Mild dermatitis with acute changes.
- Mild dermatitis with significant impact on quality of life.
Severe
- More than 30% body surface involved.
- Moderate dermatitis with acute changes.
- Moderate dermatitis with significant impact on quality of life.
GENERAL MEASURES
- Avoid exposure to trigger or precipitating factors, where applicable.
- Avoid irritants such as strong detergents, antiseptics, foam (especially hot) baths, soaps and rough occlusive clothing (silk is better than cotton, which is better than nylon, which is better than wool).
- Good personal hygiene with once daily washing to remove crusts and accretions and avoid secondary infection.
- Keep fingernails short to minimise trauma from scratching.
- Respect patient preference for cream or ointment topical treatment.
- Wet wraps may help control eczema and pruritus but should not be used for infected eczema.
- Diet modification has no role in atopic eczema treatment unless double blind challenge testing proves food sensitivity.
- Avoid smoking.
