Sağlıklı Kişilerin Kirpiklerinde Demodex folliculorum ve Demodex brevis Görülme Sıklığı

Demodex folliculorum ve Demodex brevis sadece insanlarda parazitlenen akarlardır. Genellikle hastaların yüzünde yaygın olup, kaşlarda, kirpiklerde, meibomian bezlerde, hatta vücudun diğer bölgelerinde rastlanabilmektedir. Fazla sayıda Demodex ile oluşan göz tutulumu sonrası blefarit görülebilmektedir. Çalışmada sağlıklı kişilerin kirpiklerinde Demodex türlerinin yaygınlığının belirlenmesi amaçlanmıştır. Herhangi bir kirpik enfeksiyonu geçirmemiş ve şikayeti olmayan 131 kişiden kirpik epilasyonu ile örnek alınmıştır. 17 (%12.97) kişide D. folliculorum saptanırken 4 (%3.05) kişide D. brevis görülmüştür. Fark istatistiksel olarak anlamlı bulunmuştur. Parazit varlığının cinsiyete göre değişmediği gözlenmiştir. Sağlıklı kişlerin kirpiklerinde D. brevis'e az rastlanması nedeniyle blefarit olgularına D. brevis'in D. folliculorum ile birlikte bulunmasının neden olabileceği düşünülmüştür

Prevalence of Demodex folliculorum and Demodex brevisin the Eyelash Follicles of Healthy Subjects

Demodex folliculorum and Demodex brevis mites are parasites of humans only. These mites are usually found on face, eyebrows, eyelashes and meibomian glands. When they appear in large numbers in eyelashe follicules, they may cause Demodex blepharitis. The aim of this study was to determine the prevalence of Demodex species on eyelashes of healthy individuals. Eyelashes were collected from 131 healty individuals who did not have a history of blepharitis. While D. folliculorum was detected in 17 (13.0%) people, D. brevis was only seen in four individuals (3.1%), the differences being statistically significant. It was observed that D. folliculorum occurs more commonly in older people and male/female rates were not different. Since the D. brevis was rarely found in eyelashes, cases of blepharitis are believed to be the result of the co-existance of D. brevis and D. folliculorum
