Study Notes
Rosacea Classification
- Rosacea is a common chronic skin condition characterized by facial redness, flushing, papules, pustules, and telangiectasia.
- There are four main subtypes:
- Papulopustular rosacea: characterized by papules and pustules, often on the cheeks, nose, forehead and chin.
- Erythematotelangiectatic rosacea: characterized by persistent facial redness and visible blood vessels (telangiectasia), mostly on the cheeks, nose, and forehead.
- Phymatous rosacea: characterized by thickening of the skin, particularly on the nose, resulting in a bulbous appearance.
- Ocular rosacea: characterized by eye irritation, such as burning, stinging, dryness, and a feeling of grittiness.
Rosacea Pathophysiology
- The exact cause of rosacea is unknown, but it may involve a combination of factors, including:
- Genetics: Family history of rosacea is a risk factor.
- Environment: Triggers such as sun exposure, heat, wind, alcohol, spicy foods, and stress can worsen rosacea.
- Neurovascular dysregulation: Abnormalities in blood vessel responses to triggers may contribute to the flushing and redness.
- Immune system activation: The immune system may play a role in the inflammatory response seen in rosacea.
Rosacea Triggers
- External factors that can worsen rosacea:
- Sunlight
- Heat
- Wind
- Exercise
- Hot beverages
- Spicy foods, vinegar
- Alcohol
- Emotional stress
- Use of astringents (alcohol or acetone-based products)
- Medications that can worsen rosacea:
- Vasodilators, such as
- Calcium channel blockers
- Niacin (nicotinic acid)
- Nitrates
- Phosphodiesterase-5 inhibitors (e.g., sildenafil)
- Topical corticosteroids (except low-potency or for short periods)
- Medications causing dry eyes (e.g., anticholinergics) can aggravate ocular rosacea.
- Vasodilators, such as
Rosacea Diagnosis
- Diagnosis is mainly clinical based on medical history and physical examination.
- Family history of rosacea.
- Typical age of onset is in the late 20s to 40s.
- Recurrent facial papules, pustules, flushing, and persistent color changes.
- Eye irritation, grittiness, blepharitis, dry eyes, or recurrent styes.
- Flare-ups following sun exposure.
- Physical examination:
- Persistent erythema of the central face.
- Papules or pustules, absence of comedones.
- Telangiectasia.
- Conjunctivitis, blepharitis, stye formation, or dry eye complaints.
- Phymatous changes (rare).
Rosacea Treatment
- Non-pharmacologic Options:
- Sun protection: Avoid sun exposure during peak hours, wear broad-spectrum sunscreen with SPF 30 or higher daily.
- Environmental modifications: Minimize exposure to triggers such as heat, wind, and irritants.
- Lifestyle changes: Reduce stress, limit alcohol consumption, and eat a balanced diet.
- Skin care: Use gentle cleansers, avoid harsh scrubs, and moisturize regularly.
- Pharmacologic Options:
- Topical
- Metronidazole: Antibiotic that reduces inflammation and redness.
- Azelaic acid: Antibacterial and anti-inflammatory agent.
- Topical Ivermectin: Antiparasitic agent that may reduce Demodex mite infestation.
- Oral
- Oral tetracycline: Antibiotic that reduces inflammation.
- Oral doxycycline: Antibiotic that reduces inflammation.
- Oral Ivermectin: Antiparasitic that may reduce Demodex mite infestation.
- Topical
Ocular Rosacea Treatment
- Eyelid hygiene
- Artificial tears
- Oral antibiotics (may be used)
- Topical cyclosporine eye drops
Rosacea Treatment During Pregnancy and Breastfeeding
- Topical therapy is favored for rosacea during pregnancy.
- Oral isotretinoin should be stopped at least one month before pregnancy.
- Tetracyclines are cleared from the body within one week of discontinuation.
- Special considerations:
- Isotretinoin is present in semen, but there is no known risk of harm to a fetus from paternal exposure.
- Consult with your doctor for safe and effective treatment options during pregnancy and breastfeeding.
