Atopy and alopecia areata in North Indians.
The study was undertaken with the aim of evaluating the effect of associated atopy on severity and age at onset of alopecia areata in north Indians. Presence of atopy was elicited by detailed history, examination and intracutaneous tests. Chi square test was carried out to evaluate statistical significance. One hundred patients (76 males and 24 females) with alopecia areata were evaluated. Historical evidence of atopy was present in 50 including patients alone (23), patients and first degree relatives (11) and first degree relatives alone (16). Intracutaneous tests were positive in 23 out of 50 patients tested randomly. There was a trend towards increasing frequency of severe alopecia as evidence of atopy became stronger e.g. both patient and first degree relatives with atopy or positive intracutaneous test but the results did not attain statistical significance. Similarly the age at onset and duration of alopecia areata was not significantly related to the presence of atopy. It is concluded that in north Indians with alopecia areata, the presence of atopy is not significantly associated with severe alopecia or onset at younger age.
