Demodicosis – pathophysiology, treatment and therapeutic efficacy of metronidazole ointment and mercury oxide ointment
Main Article Content
Abstract
Two species known to infest humans are Demodex folliculorum and Demodex brevis. Infestation by Demodex sp. is known as demodicosis. Demodicosis is currently typically managed with a metronidazole ointment, mercury oxide ointment, essential oils, ivermectin or Infectosab (permethrinum 5%). The aim of the study was to efficacy of mercury oxide ointment and metronidazole ointment in the treatment of patients with demodicosis. The therapeutic efficacy of mercury oxide ointment was tested in 49 patients and metronidazole ointment in 42 patients. Material for this study were eyelashes collected from patients. Treatment was considered effective when patient on the first or subsequent control visit did not have any Demodex mites in eyelashes. The efficacy of mercury oxide ointment and metronidazole ointment was demonstrated in 37% and 10% of cases, respectively.
