A randomized controlled trial of efficiency and safety of liquid powder containing tapioca starch stimutex AS, aloe barbadensis, rose hip oil and allantoin comparing with topical 1% hydrocortisone cream for the treatment of intertrigo

Intertrigo is an inflammatory dermatosis involving body folds that develops through friction of skin to skin and is influenced by moist conditions. The prevalence of intertrigo was reported to be 2.5% for adults with an average age of 41.5 years. Prevalence of intertrigo in the large skin folds varies from 6% in hospital patients to 17% in nursing home clients and 20% in home care patients. The inframammary fold was most often affected (9.9%), followed by the inguinal region (9.4%), axilla (0.5%) and abdominal region (0.5%). Intertrigo may be mild and asymptomatic, but also may lead to intense erythema and desquamation. The affected skin may have a foul odor and may be macerated and ulcerated with copious or purulent discharge. The conventional therapy for simple intertrigo is minimizing moisture and friction. Some suggest the use of absorptive powders, such as talc and cornstarch, or barrier creams. These topical treatments such as topical steroid, however, have little or no proven benefit and may cause irritation or facilitate yeast colonization. This study aims to evaluate the efficacy and safety of liquid powder containing tapioca starch stimutex AS, aloe barbadensis, rose hip oil and allantoin comparing with topical 1% hydrocortisone cream of mild to moderate intertrigo patients.

Inclusion Criteria:

1. Patients who had age more than 18 years
2. One intertrigo lesion at inframammary fold, inguinal region, interdigital, axilla or abdominal region with mild to moderate which only has erythema no epidermal loss
3. Being diagnosed intertrigo by dermatologist. Patients will be clinical and investigational with KOH preparation and Wood's lamp diagnosed with intertrigo by dermatologist.

Exclusion Criteria:

1. Patients receive topical steroids, topical anti-fungal drugs within 2 weeks prior the study
2. Patients with skin conditions including fungal/bacterial infection, Hailey-Hailey disease, pemphigus, granuloma, psoriasis, acanthosis, or Darier disease on intertriginous areas within 2 weeks prior to the study
3. Patients with an allergic to tapioca starch และ stimutex AS, aloe Barbadensis, rosa hip oil และ allantoin, or topical hydrocortisone
4. Pregnant or breastfeeding women
5. Patients with severe intertrigo treated with high potent topical steroid or systemic corticosteroid

the two interventions were prepared in an identical neutral package. The same investigator evaluated the skin condition at each follow-up visit. Patients were followed up at 2 weeks.
