Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention will be randomised between 3 possible interventions described below; children with 3 or less impetigo lesions will be enrolled and all lesions will be managed

1. Topical fusidic acid ointment 2% twice a day for 5 days - Fusidic acid 2% ointment (15g tube supplied) with single occasion wound cleaning by a nurse and topical fusidic acid ointment applied to each lesion then covered with occlusive dressing. Ongoing twice daily ointment and dressings twice daily will be done by parent/carer with instructions supplied with no adherence monitoring other than verbal review with nurse on Day 2 and day 7

Intervention 2. Topical hydrogen peroxide 1% (10g tube) applied twice a day for 5 days. Initial wound cleaning by nurse and H2O2 cream applied to each lesion then covered with an occlusive dressing. The topical antiseptic and sufficient dressings will be supplied to the family along with instructions with no adherence monitoring other than verbal review with nurse on Day 2 and day 7

Intervention 3: Wound care: the wound will be cleansed, scab softened and removed where possible, then covered with an occlusive dressing. Sufficient dressings will be supplied to the family along with instructions to cleanse and reapply dressing twice a day for 5 days with no adherence monitoring other than verbal review with nurse on Day 2 and day 7.

Assessment of lesions will be done ongoing at day 2 and day 7 after enrollment

Outcomes
Primary outcome [1] 297631 0
The primary outcome is treatment success as evaluated by review of digital images on day 0-7.
Independent reviewers (clinician including paediatrician x4, dermatologist x2) masked to treatment allocation will compare digital images of skin lesions from days 0 and 7. The order of the images when reviewed will be randomly assigned to ensure further blinding. Outcomes will be scored as success if they have healed or improved and failure if same or worse, or if the reviewer was unable to determine success or failure compared to day 0. Assessment criteria will be adapted from trial and methodology published by Bowen et al. Lancet ID 2014 Dec 13;384(9960):2132-40.
Timepoint [1] 297631 0
Primary time endpoint is outcome at Day 7
Digital images of skin lesions will be taken on Days 0 and 7
Secondary outcome [1] 321646 0
Secondary outcome
Number of treatment failures on both Day 2 and Day 7
This includes children assessed as needing change management of lesions such as escalation to oral antibiotics, visiting their general practitioner for concerns over the skin infection, or admission to hospital or medical review.

.

Timepoint [1] 321646 0
Treatment failures will be assessed by clinical review at day 2 and day 7 post treatment commencement by school/study nurse.
Secondary outcome [2] 321863 0
Clinical success at Day 7 based on nurse assessment using clinical notes, lesion size, patient report and clinical nursing assessment
Timepoint [2] 321863 0
Clinical success will be assessed by clinical review (at day 2) and day 7 post treatment commencement by school/study nurse.
Secondary outcome [3] 321864 0
Secondary outcome microbiologic based on detection of skin pathogens at Day 0 and Day 7 and comparison of antibiograms of isolated S.aureus and S.pyogenes from skin swabs
Timepoint [3] 321864 0
Swabs and cultured Day 0 and Day 7 of a single lesion

Efficacy
Statistical methods / analysis
To show no difference between treatment regimens and a predicted fusidic acid efficacy of 75% (as per previous published trials)we calculated that 160 participants per group are required: 480 children in total
This would provide 80% power and a one-sided a=0.05 to show non-inferiority (10% margin) between the groups

Summary
Brief summary
Skin sepsis is a common problem among children and severe skin infections are the most common reason for hospitalisation in NZ children. Pacific and Maori children are more likely to develop cellulitis than their NZ European counterparts and hospital admissions for skin sepsis occur at more than twice the rate in NZ compared with other developed countries. Evidence-based clinical guidelines for the treatment of mild to moderate impetigo recommend the use of fusidic acid cream, currently funded topical antimicrobial in NZ. Recent data, however, have identified a high rate of community resistance to this medication amongst Staphylococcus aureus (SA) ; resistance >30%. This is linked to widespread community use of this topical antibiotic. The evidence base for alternative treatment strategies for mild impetigo is limited and judicious use of topical antibacterials is needed. Alternative therapies must be urgently found to prevent increasing resistance.
The overall aim of the research is to compare two alternative treatments with the current standard of care treatment for mild-to-moderate impetigo among school children.
Aims To undertake a non-inferiority trial comparing topical fusidic acid with (i) topical hydrogen peroxide, and (ii) with simple wound care in a community with both high rates of impetigo and increasing fusidic acid resistance.
The results of this trial will inform evidence-based skin infection guidelines locally, nationally, and internationally including funding of best treatments.
