Background and purpose: Seborrhoeic dermatitis (SD) is a common skin disorder. Malassezia yeasts have an important role in the etiology of SD. Since anti-fungal agents, especially in azoles are effective for treating SD, in this study, the effect of ketoconazole 2% solution on clinical signs and Malassezia in SD patients were assayed.
Materials and methods: 100 patients with SD were enrolled in this study. Patients were scored in regard to the severity of lesions at the initial evaluation and every 2 weeks for a 1 month period. Microscopic examination and culture of patients scale in days 0 and 28 were used for isolation and identification of Malassezia species. Patients were divided into two groups (ketoconazole 2% solution and shampoo) and followed after 14 and 28 days, and then clinical response was graded.
Results: 58% of patients showed lesions on their heads. In day 0, 51% of patients showed > 7 yeasts in each microscopic field. 77% of scale samples were positive to Malassezia spp. Growth and M. globosa (57.1%) had the most frequency. In day 28, 89.6% and 82.6% of treated patients with solution and shampoo showed 1-3 yeast in within entire smear, respectively. 94.8% and 82.6% of scale samples were negative to Malassezia spp growth, respectively. In day 0, patients with moderate SI had the most prevalence, whereas in day 28, patients with mild SI were predominant. Statistical test showed the correlation is significance only between SI and treatment with solution.
Conclusion: The results of our study showed that according to decrease of yeast load and increase of improvement of SD signs after treatment with ketoconazole 2% solution, compared with ketoconazole 2% shampoo, 2% ketoconazole solution can be considered as an appropriate agent in treatment of Sd.
