Diagnosis and Treatment of Acne

Acne can cause significant embarrassment and anxiety in affected patients. It is important for family physicians to educate patients about available treatment options and their expected outcomes. Topical retinoids, benzoyl peroxide, sulfacetamide, and azelaic acid are effective in patients with mild or moderate comedones. Topical erythromycin or clindamycin can be added in patients with mild to moderate inflammatory acne or mixed acne. A six-month course of oral erythromycin, doxycycline, tetracycline, or minocycline can be used in patients with moderate to severe inflammatory acne. A low-androgen oral contraceptive pill is effective in women with moderate to severe acne. Isotretinoin is reserved for use in the treatment of the most severe or refractory cases of inflammatory acne. Because of its poor side effect profile and teratogenicity, isotretinoin (Accutane) must by prescribed by a physician who is a registered member of the manufacturer's System to Manage Accutane-Related Teratogenicity program.

Acne is a disease of pilosebaceous units in the skin. It is thought to be caused by the interplay of four factors. Excessive sebum production secondary to sebaceous gland hyperplasia is the first abnormality to occur.1 Subsequent hyperkeratinization of the hair follicle prevents normal shedding of the follicular keratinocytes, which then obstruct the follicle and form an inapparent microcomedo.2 Lipids and cellular debris soon accumulate within the blocked follicle. This microenvironment encourages colonization of Propionibacterium acnes, which provokes an immune response through the production of numerous inflammatory mediators. Inflammation is further enhanced by follicular rupture and subsequent leakage of lipids, bacteria, and fatty acids into the dermis.

Diagnosis

The diagnosis of acne is based on the history and physical examination. Lesions most commonly develop in areas with the greatest concentration of sebaceous glands, which include the face, neck, chest, upper arms, and back.

Acne vulgaris may be defined as any disorder of the skin whose initial pathology is the microscopic microcomedo.3 The microcomedo may evolve into visible open comedones ("blackheads") or closed comedones ("whiteheads"). Subsequently, inflammatory papules, pustules, and nodules may develop. Nodulocystic acne consists of pustular lesions larger than 0.5 cm. The presence of excoriations, postinflammatory hyperpigmentation, and scars should be noted.

Acne may be triggered or worsened by external factors such as mechanical obstruction (i.e., helmets, shirt collars), occupational exposures, or medications. Common medications that may cause or affect acne are listed in Table 1.4 Cosmetics and emollients may occlude follicles and cause an acneiform eruption. Topical corticosteroids may produce perioral dermatitis, a localized erythematous papular or pustular eruption.5

Endocrine causes of acne include Cushing's disease or syndrome, polycystic ovary syndrome, and congenital adrenal hyperplasia.6 Clinical clues to possible hyperandrogenism in women include dysmenorrhea, virilization (i.e., hirsutism, clitoromegaly, temporal balding), and severe acne.

Classification

In 1990, the American Academy of Dermatology developed a classification scheme for primary acne vulgaris.7 This grading scale delineates three levels of acne: mild, moderate, and severe. Mild acne is characterized by the presence of few to several papules and pustules, but no nodules . Patients with moderate acne have several to many papules and pustules, along with a few to several nodules . With severe acne, patients have numerous or extensive papules and pustules, as well as many nodules.

Acne also is classified by type of lesion-comedonal, papulopustular, and nodulocystic. Pustules and cysts are considered inflammatory acne.
