Diagnosis and treatment of rosacea: state of the art.
Rosacea is a common disorder that is both under recognized and undertreated. Prevalence figures indicate that it may be present in 1 of every 10 adults in a primary care waiting room. Untreated, patients with rosacea can suffer significant emotional, workplace, and social impairments. While rosacea has been recognized since ancient times, only recently have investigators begun to identify the pathophysiologic elements responsible for the characteristic erythema, flushing, dysesthesias, and papulopustular manifestations of the disease. Although the etiology of rosacea is unclear, inflammation appears to be a central element. Experimental evidence suggests that abnormalities of the skin's innate and adaptive immune responses may play pivotal roles. Once recognized, effective topical and systemic therapies can be prescribed to lessen the impact of the disease on the patient's life. Although initially administered in an empiric fashion, it now seems clear that the role of antibiotics in patients with rosacea depends upon their anti-inflammatory rather than their antimicrobial properties. Consequently, practitioners have the opportunity to practice good antibiotic stewardship when treating the disease, particularly with systemic therapies. Therapy with subantimicrobial dosing and with topical treatments can modulate the inflammation of rosacea without exerting antibiotic pressure responsible for the emergence of antibiotic resistance.
