Diagnosis and management
Without definitive laboratory tests, it’s essential that the clinical diagnosis takes into account not only the physical examination findings, but also patient history, the authors stressed, since “some features may not be visually evident or present at the time of the patient’s visit.”
The authors also recommend taking into account patients’ perception and response to their appearance and its effects on their emotional, social, and professional lives when selecting interventions.
“Rosacea’s unsightly and conspicuous appearance often has significant emotional ramifications, potentially resulting in depression or anxiety, and frequently interferes with social and occupational interactions,” the authors wrote. “It may also be advisable to remind patients that normalization of skin tone and color is the goal rather than complete eradication of facial coloration, which can leave the face with a sallow appearance.”
Therapy will often require multiple agents, such as topical and oral agents for inflammatory papules/pustules of rosacea. If insufficient, adjunctive therapy with oral antibiotics or retinoids may be options, though the latter requires prevention of pregnancy during treatment. The authors also discussed pharmacological treatments for facial erythema and flushing, with all these drugs organized in tables according to symptoms and their levels of evidence and effectiveness.
Despite limited clinical evidence, the authors noted success with two types of laser therapy – pulsed-dye and potassium titanyl phosphate – for telangiectasia and erythema. They also noted the option of intense pulsed light for flushing, ocular symptoms, and meibomian gland dysfunction, and of ablative lasers for rhinophymatous nose. But they highlighted the importance of being cautious when using these therapies on darker skin.
In their discussion of ocular rosacea, the authors described the various manifestations and the two “mainstays” of treatment: “eyelash hygiene and oral [omega-3] supplementation, followed by topical azithromycin or calcineurin inhibitors.” In addition to pharmacological and light therapy options, attention to environmental contributors and conscientious skin care regimens can benefit patients with rosacea as well.
“Clinicians may advise patients to keep a daily diary of lifestyle and environmental factors that appear to affect their rosacea to help identify and avoid their personal triggers,” the authors wrote. “The most common factors are sun exposure, emotional stress, hot weather, wind, heavy exercise, alcohol consumption, hot baths, cold weather, spicy foods, humidity, indoor heat, certain skin-care products, heated beverages, certain medications, medical conditions, certain fruits, marinated meats, certain vegetables, and dairy products.”
The paper also emphasizes the importance of gentle skin care given the highly sensitive and easily irritated skin of patients with rosacea. Sunscreen use, particularly with mineral sunscreens that provide physical barriers and reflect ultraviolet light, should be a key aspect of patients’ skin care, and clinicians should advise patients to seek out gentle, nonirritating cleansers.
