Abstract

Background: Acne is a common disorder, associated with inflammation of the sebaceous and bacterial hair follicle units and has diverse clinical manifestations. The most commonly mentioned causes and factors associated with the onset of acne in adulthood are hormones, antibiotic-resistant bacteria, and the use of drugs and cosmetics. In particular, the increase in the number of Demodex mites due to the habit of using cosmetics of unknown origin, has caused complicated clinical symptoms and difficulties in the treatment of acne today. Objectives: To determine the prevalence, clinical characteristics and some related factors in patients with acne vulgaris superinfected with Demodex. Materials and methods: A cross-sectional descriptive study with analysis was conducted on 154 acne vulgaris patients visiting medical facilities in Can Tho city in 2021-2023. Results: The study included 154 acne vulgaris patients with an average age of 22.16 ± 6.739 years old, with males constituting the majority. Among the patients, 29.87% had Demodex infestation, and 9.74% of them had a Demodex density of 5 or more mites. The majority of acne cases were of moderate or higher severity, with the most severe cases accounting for 85.7% of those with Demodex presence. Clinical features observed in patients with Demodex infestation included closed comedones (97.8%), open comedones (93.5%), papules (63%), pustules (60.9%), and cystic nodules (52.2%). Additionally, 93.5% and 91.3% of patients reported symptoms of peeling skin, but only 50% reported a feeling of ants, which appeared to be related to Demodex infection in acne patients. Furthermore, habits such as sharing towels, makeup, and wearing masks for more than 8 hours were identified as risk factors for Demodex infection. Conclusions: The presence of Demodex in acne patients is associated with a variety of clinical manifestations, including acne accompanied by skin peeling, scaling, and itching sensation. The relationship between Demodex infestation and the sensation of ants requires further investigation. Additionally, papules, pustules, and crawling sensations were also found to be related to Demodex infection. Moreover, certain habits, such as sharing towels, using makeup, and wearing masks for prolonged periods, appear to be risk factors for Demodex infection in acne patients
