J Allergy Clin Immunol. 2009 Sep; 124(3S2): R13-R18Schauber J, Gallo RLOur skin is constantly challenged by microbes but is rarely infected. Cutaneous production of antimicrobial peptides (AMPs) is a primary system for protection, and expression of some AMPs further increases in response to microbial invasion. Cathelicidins are unique AMPs that protect the skin through 2 distinct pathways: (1) direct antimicrobial activity and (2) initiation of a host response resulting in cytokine release, inflammation, angiogenesis, and reepithelialization. Cathelicidin dysfunction emerges as a central factor in the pathogenesis of several cutaneous diseases, including atopic dermatitis, in which cathelicidin is suppressed; rosacea, in which cathelicidin peptides are abnormally processed to forms that induce inflammation; and psoriasis, in which cathelicidin peptide converts self-DNA to a potent stimulus in an autoinflammatory cascade. Recent work identified vitamin D3 as a major factor involved in the regulation of cathelicidin. Therapies targeting control of cathelicidin and other AMPs might provide new approaches in the management of infectious and inflammatory skin diseases.
The specific treatments for rosacea is determined by your physician based on: Your age, general health and medical history. How advanced is the eruption. Tolerance to specific medications, procedures or therapies. Their expectations for the trajectory of the eruption. Your opinion or preference. Treatments for rosacea may include : Modifications to diet Antibiotics. Cortisone ointment. Laser surgery Use sunscreen with a sun protection factor Currently there are several treatments for rosacea are used, depending on the events that it has. At the initial stage, to prevent the dilation of blood vessels and the consequent need to avoid red hot environments, exposure to sunlight, extreme changes in temperature and food hot or too much seasoning. When pustules that resemble pimples, prescribed oral antibiotics such as tetracycline. Another alternative treatments for rosacea is the topical antibiotics such as metronidazole. Also is using retinoids, which regulate the sebum production of the ...
