The Retrospective Analysis of Demodex spp. Results in Aydın Adnan Menderes University Faculty of Medicine Hospital Parasitology Laboratory.

Abstract

Demodex spp. is one of the most common ectoparasites in humans. The aim of the present study is to evaluate the positivity of Demodex spp. in our Parasitology Laboratory, retrospectively. The study included Demodex spp. suspected cases from different departments between 2008 and 2017. The link between Demodex spp. and demographics and symptoms was investigated. In addition, Demodex spp. was evaluated regarding symptoms and distribution pattern (U, T and diffuse region). Demodex spp. was detected in 576 (78%) of 738 cases. There was no relationship between sex and parasite positivity, but frequency was lower in cases below 19 years. There was a relationship between presence of parasite and redness, itching, burning and rash. The parasite density was higher in U region (n=335, 58.2%). When clinical findings and parasite number were statistically compared; itching, burning and rash were significantly higher in patients with parasite density ≥5 parasites/cm2, while a similar result was not observed in patients with redness. Given its prevalence and its relationship with the clinical findings; we believe that Demodex is an important parasitic disease for our province and should be evaluated in cases with various dermatological complaints in the face.
