Plain English Summary

Background and study aims
Steroids are important medications, but they are associated with side effects, the most serious is suppression of the adrenal glands. Adrenal suppression can be life threatening so people taking steroid medicines are given a 'Steroid Treatment Card' to help everyone know that they are at risk. Very high doses of steroid cream may cause adrenal suppression although the amount of cream that causes this problem is not well known. Recently we have been advised to give steroid treatment cards to all children given steroid cream to treat abnormal genital skin, even though the amount of cream used is quite small. This is because genital skin is thin and may absorb more steroid medicine compared to other parts of the body. There are no research studies looking at how much cream would cause a problem though blood tests in a small number of girls treated for Lichen sclerosus (who need to use more cream) do suggest a problem.

Steroid treatment cards may cause worry, some patients may not use the cream as advised because of that. This study will measure the level of children's own steroid hormones before, during and after a course of treatment with steroid cream to their genitalia. The tests will be done in a non-invasive way (no blood tests!) by measuring cortisol and cortisone in saliva. The aim is to see if the amount of cream used to treat a common problem in boys (non-retractile foreskin) and an uncommon but related condition in girls (lichen sclerosus) causes adrenal suppression. The study will recruit 50 boys and 5 girls over 1 year, if there is no sign of a problem then the study will end but if there is any suspicion of adrenal suppression then a substantive study will be designed.

Who can participate?
Any boy or girl over the age of 5 who is given steroid cream to treat a problem with their genital skin can participate in the study.

What does the study involve?
The study involves giving some spit (saliva) samples before, during and after treatment. The samples are collected early in the morning, before breakfast, on nine days in total. The samples are stored in the participants home freezer until they next come to the hospital.

What are the possible benefits and risks of participating?
There are no direct benefits from taking part but participating will help other children who need the same treatment in the future. There are no risks to taking part but it may be inconvenient to take the samples before eating or cleaning your teeth.

Where is the study run from?
Alder Hey Children's Hospital (UK)

Scientific titleMonitoring Of Salivary cortisol in Anogenital skin Inflammation treated with topical Corticosteroids
Study acronymMOSAIC
Study hypothesisTo determine whether potent, topical steroid creams, applied to genital skin in children, result in significant changes in early morning salivary cortisol and cortisone concentrations from baseline measurements.
Ethics approval(s)

Approved 26/07/2023, Stanmore REC (2 Redman Place, Stratford, London, E20 1JQ, United Kingdom; +44 207 104 8194; stanmore.rec@hra.nhs.uk), ref: 23/PR/0764

ConditionTreatment of lichen sclerosus or non-retractile foreskin in children.
InterventionChildren who need to use steroid creams on genital skin will give saliva samples by chewing on a cotton wool roll and their salivary steroid levels will be measured. Girls and boys will take part but the reason for their treatment may be different.

In the study the girls will give saliva samples just before they start treatment, part way through and just after treatment to see if the saliva test is just as good as the blood tests.
Treatment takes 3 months and the study is complete once the treatment course is finished and the final set of saliva samples has been collected.

Boys, on the other hand, only need to use a small amount of steroid cream and they do not have to have routine blood tests. Boys and girls get given a ‘steroid alert card’, the card warns they might have a fall in steroid levels. In girls that can happen so the card is important but in boys the chance is very low and the card can cause a lot of worry. If the natural body steroid levels do not actually fall in boys then boys do not need to have a card. In the study boys will give saliva before their treatment, just after the treatment (after 6 weeks) and a month later, then the study is complete.
Intervention typeOther
Primary outcome measure1. BOYS - change in EMSC and EMSCn from baseline to end of treatment (after 6 weeks) and one month following treatment measured by a laboratory test of salivary cortisol and cortisone
2. GIRLS - change in EMSC and EMSCn from baseline to the end of the first 4 weeks of treatment and at the end of treatment (after 3 months) measured by a laboratory test of salivary cortisol and cortisone
Secondary outcome measures1. Number of patients with EMSC or EMSCn >2 standard deviations below the mean of a cohort of healthy child volunteers measured by a laboratory test of salivary cortisol and cortisone at the end of the study
2. Percentage change in EMSC/EMSCn measured by a laboratory test of salivary cortisol and cortisone at the end of the study
3. Amount of steroid used according to age and sex measured in grams of cream used from the prescribed tube at the time of returning samples
4. Acceptability of and compliance with the study protocol measured through number of samples returned and informal discussion with participants at the time of returning samples
5. Protocol completion measured by number of children completing study and number of samples actually taken compared to number expected at the end of the study
6. Adequacy of samples measured by a laboratory test of salivary cortisol and cortisone at the time of analysis
7. Number of children requiring referral to endocrinology for further evaluation measured using patient records at the end of the study

Target number of participants55
Participant inclusion criteriaBOYS: Males 5-15 years who are treatment naïve (no steroid medication of any kind in the previous 3 months) receiving potent topical steroid for pathological or physiological phimosis.

GIRLS: Pre-pubertal females aged 5-15 years who are treatment naïve (no steroid medication of any kind in the previous 3 months) receiving very potent topical steroid for LS following diagnosis made in the paediatric gynaecology/dermatology clinics.
Participant exclusion criteria1. Patients with oral conditions which could contaminate saliva samples with blood, such as current mouth ulcers or gingivitis.
2. Patients taking additional medications which are likely to impact on cortisol levels e.g. glucocorticoids, sex steroids, thyroxine, growth hormone, insulin, metformin, opiates, loperamide and azole compounds.
3. Children with a family history of adrenal insufficiency due to an inherited condition, including congenital adrenal hyperplasia.
4. Children <5 years of age and children at high risk of choking on the cotton wool roll used to collect the saliva.
5. The treating clinician does not consider it appropriate to delay treatment whilst the family consider the study and take the pre-treatment samples.
6. Recent (within 3 weeks) ingestion of liquorice
