Background:
Hanifin and Rajka criteria are considered to be the gold standard for atopic dermatitis diagnosis. However, the exhaustive nature limits its use in clinical settings.
Objective:
To determine the frequency of Hanifin and Rajka criteria commonly found in Indian pediatric atopic dermatitis patients and variation from the findings of other studies.
Material And Methods:
An observational, descriptive study with a sample size of 52 pediatric atopic dermatitis patients. Patients were divided into infantile, childhood, and adolescent.
Results:
Overall, xerosis, early age of onset, Dennie-Morgan fold, aggravation because of environmental factors, palmar hyper-linearity, ichthyosis vulgaris, keratosis pilaris, pityriasis alba, and orbital darkening were found in more than 50% of patients. Dennie-Morgan fold was more commonly found in Indian pediatric atopic dermatitis patients. Peri-follicular accentuation was less prevalent in Indian patients as compared to other Asian studies. None of the parents reported food intolerance, which was seen in studies from other countries.
Limitations:
A small sample size and ophthalmological evaluation was not performed in all patients.
Conclusion:
The frequency of different Hanifin and Rajka minor criteria varies widely among different study populations. Hence, the criteria specifically applicable to the Indian population need to be derived for ease of diagnosis.
