The Role Of IL-4 And IL-8 In The Itiology Of Tinea Versicolor In Group Of Iraqi Patients


Background: Tinea versicolor is a common dermatological problem ,world wide distribution ,caused by a dimorphic fungus called Malassezia furfur ,it live normally on skin as a commensal .Many factors play a role in the etiology of TV among these could be the disturbed immune systemwhich may be related to the ability of TV alter the immune system by a process calledImmunomodulation leading to subsequent infection.Immuno-inflammatory activity mediated by different cytokines could have a role in the etiologyof TV.Objective: To evaluate the serum level of the inflammatory cytokines ,IL-4andIL-8,in patients withTV as compared to immunocompramized patients and healthy groups.Patients and methods: This study enrolled 50 total patients, 15 of them were as patients controlgroup who were immunocompramized with evident skin lesion ,to be compared serologically with 15patients who had TV and normal immunity, the control group composed of20 healthy volunteers.Using ELISA test technique the following tests were done :detection of IL-4 and IL-8 in the sera ofall groups.Results and discussion: The statistical differences in the rate of detectable IL-4 level between TVand healthy control p< 0.001,while the difference was a highly significant between the healthycontrol and immunocompramized patients with TV,P<0.00338.The difference between twodiseased groups was(p< 0.219)which is non significant , when p<0. 05 was considered significant.IL-8 the results of our study showed a significant difference between the healthy control and thepatients with tinea versicolor, p-value was( 0.05).In this study there was a nice findings by which the difference between the healthy control and theimmunocompramized patients was highly significant as ,p<0.005.Conclusion :The genus Malassezia is an immunological paradox. In some circumstances, it actsas an adjuvant, activates the complement cascade, and elicits both cellular and humoral immuneresponses in healthy individuals, among which IL8 and IL-4 were notably increased . In contrast,it also seems to have the ability not only to evade the immune system but actually to suppress theresponse directed against
