Abstract

Background: Topical corticosteroids are the most commonly used drug and mainstay of dermatotherapeutics for many dermatoses. Topical corticosteroids are irrationally combined with other medications and widely available as the over the counter preparations (OTC) and are widely misused for various conditions. Dermatophytosis is a superficial fungal infection which is becoming resistant and difficult to treat because of inappropriate usage of irrational combination of topical corticosteroid
containing preparations (ICSP).
Aims and Objective: To study the prevalence and factors which promotes the abuse of Irrational combination of topical corticosteroid containing preparations(ICSP) in dermatophyte infection.
Materials and Methods: A Prospective observational study conducted at department of Dermatology, Venereology & Leprosy in a tertiary care centre, South India. The sample size of this study is n=55.
Results: Out of 55 patients most common age group is 15 -30 years (n=16,29.09%).Females (n=30,54.54%) predominated over males with male:female ratio of 0.83:1.The most common complaint was intractable itching (n=46,83.64%) .The majority of study group had disease duration was 0-1 months (n=27,49.1 %) with mean duration of 4 months. The main source of referral was Over the counter (OTC) (n=32,58.18%). The most common irrational combination was FDC 3 combination (30.9%). Most commonly abused brand was betnovate GM(n=17,30.9%).Most of the patients used Clobetasol propionate 0.05% (n=25,45.5%).Patients were using ICSP mostly for less than 1 month (n=27,49.1%),with intermittent(n=19,34.5%) frequency of application. Most common side effect was tinea incognita (n=33,60%).Potassium hydroxide mount was positive in 25 patients(45.45%).Fungal culture was done in all patients and 12 patients(21.81%) showed growth. The commonest organism isolated among culture positive specimen was Trichophyton rubrum(12.72%).
Conclusion: Inappropriate usage of irrational combination of topical corticosteroid containing preparations (ICSP) in dermatophyte infection induces short term clearance whereas the long term side effects results in variable presentation. Awarness of this problem leads to prevention of steroid modified dermatophytosis which is the rising menace.
