J Drugs Dermatol. 2009 Jul; 8(7): 664-8Del Rosso JQAnti-inflammatory dose doxycycline (ADD), which is the administration of doxycycline 40 mg extended-release capsule once daily, is the only oral therapy approved by the United States Food and Drug Administration (FDA) for treatment of rosacea. ADD once daily has been shown to exhibit anti-inflammatory activity while not demonstrating evidence of antibiotic effects, including with chronic administration. This article summarizes the clinical studies to date on the use of ADD once daily in papulopustular rosacea, including both monotherapy and combination therapy studies. The combination therapy approach of ADD once daily and metronidazole gel 1% once daily has been shown to exhibit a more rapid onset of therapeutic effect than topical therapy alone. ADD once daily has been demonstrated to be effective in adult subjects with moderate to severe rosacea, and exhibits a favorable safety profile coupled with absence of antibiotic selection pressure. Additionally, a much lower incidence of gastrointestinal side effects has been noted with ADD once daily as compared to doxycycline 100 mg once daily.
To estimate the prevalence of dry eye and to investigate its relationship with lifestyle and systemic factors in a general adult population in north-western Spain. METHODS: A dry eye questionnaire was administered and objective tests were performed in 654 individuals [mean age (Standard deviation): 63.6 (14.4) years, range: 40-96, 37.2% males]. Subjects were considered symptomatic when one or more of the symptoms of the questionnaire were present often or all the time. Schirmer test or= 3 and fluorescein staining >or= 1 were considered indicative of signs. Dry eye was defined as the simultaneous presence of symptoms and at least one sign. A design based analysis was performed and all calculations were weighted to give unbiased estimates. RESULTS: Dry eye prevalence was 11.0% (95%confidence interval [CI] 8.6-13.3). Dry eye was found to be more frequent in women (11.9%, 95%CI 8.8-15.1) than in men (9.0%, 95%CI 5.3-12.6), and was significantly associated with aging (p autoimmune diseas...
