Abstract | ||||
Background: Acne vulgaris is a common chronic inflammatory disease of the pilosebaceous unit, characterized by the formation of open and closed comedones, papules, pustules, nodules and cysts. It is the most common disorder treated by the dermatologists. This work aims to evaluate the role of Adapalene in treatment of acne vulgaris. Methods: The study was conducted on 20 patients with acne vulgaris. The age of patients ranged from 16 to 33 years, a 2mm punch biopsy was taken before and after the treatment. Results: Clinical improvement in most of cases which was in the form reduction in the count of acne lesions after 12 weeks of treatment and reduction in the inflammatory infiltrate in the skin biopsies. Conclusion: Adapalene is effective in treatment of acne vulgaris. | ||||
Highlights | ||||
Conclusion Acne vulgaris is a disease of the pilosebaceous unit, resulting from the interplay of different factors including; seborrhea, P. acnes coloni-zation, hyperkeratinization of the follicular duct and release of inflammatory mediators. Increased sebum lipogenesis by sebaceous gland is considered the major one involved in the pathophysiology of acne. And conclusion, the present study revealed that adapalene is effective in the treatment of acne vulgaris lesions with minimal downtime. | ||||

Introduction Acne is a chronic inflammatory condition of the pilosebaceous unit(1). It causes non inflam-matory lesions (open and closed comedones), inflammatory lesions (papules, pustules, and nodules), and varying degrees of scarring(2) Its pathophysiology involves three actors, increase sebum production, abnormal follicular keratini-zation and bacterial proliferation in the pilosebaceous unit(3). The initial acne lesion is the microcomedone, which is microscopic structure. During the course of acne, non-inflammatory lesions form, including closed (whiteheads) and open (blackheads) comedones, followed by inflam-matory lesions that include superficial lesions such as a papules and pustules (≤5mm in diameter) and deep pustules or nodules (4). Acne leads to significant morbidity that is associated with residual scarring and psychological disturbances such as poor self-image, depression, and anxiety, which leads to a negative impact on quality of life. (5) Treatment of acne vulgaris includes topical and systemic treatments. Topical modalities is useful in mild and moderate acne, as single agent treatment, in combination and also as maintenance therapy, while systemic treatment used in severe acne vulgaris (6). The aim is to evaluate the role of adapalene in treatment of acne valguris Subjects and Methods The present study has been conducted on 20 patients with mild to moderate acne vulgaris attending the outpatient clinic of the Depart-ment of Dermatology, STDs and Andrology, Minia University Hospital. All patients were females. The age of patients ranged from 16 to 33 years. They were attending the Dermatology outpatient clinic of Minia University Hospital in the period from January 2019 to June 2020.
All patients were subjected to full history taking, examination, photography and biopsy before and after the treatment The severity of inflammation was graded according to (Barakat et al., 2016)(7) as follows;
Statistical analysis Data were statistically analyzed using SPSS program. The statistical difference before and after treatment was expressed in p value which was considered significant when it was ˂ 0.05.
Results We noticed clinical improvement in most of cases which was in the form of decrease the number of non-inflammatory, inflammatory and total acne lesions after 12 weeks of treatment (fig1). Fig. (1): excellent improvement after the treatment. There was reduction percentage in the 3 forms of lesion as follows (0%, 63.3%, 55.6%) after the treatment and there was statistically significant difference before and after the treatment (p<0.001). After Adapalene treatment, the infiltrate score significantly decreased (P value = <0.001). Fig. (2): showing significant reduction in the inflammatory infiltrate after the treatment.
Discussion Acne vulgaris is a disease of the pilosebaceous unit, resulting from the interplay of different factors including; seborrhea, P. acnes coloni-zation, hyperkeratinization of the follicular duct and release of inflammatory mediators. Increased sebum lipogenesis by sebaceous gland is considered the major one involved in the pathophysiology of acne (8). Adapalene (ADP) is a representative of the third retinoids generation and successfully used in first-line acne treatment. ADP binds to retinoic acid nuclear receptors. The comedolytic, anti- inflammatory, antiproliferative, and immune-modulatory are the known ADP effects. Its safety profile is an advantage over other retinoids (9) | ||||
