Anti-inflamatory dose doxycycline in the treatment of rosacea.

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.

Helicobacter pylori and its eradication in rosacea

Rosacea is a common condition of unknown etiology usually accompanied by gastrointestinal symptoms and favorably responding to the treatment with antibiotics. This study was designed to examine the prevalence of gastric Helicobacter pylori (Hp) infection verified by 13C-UTB-test, CLO, Hp culture and serology (IgG) in patients with rosacea. Gastroduodenoscopy was combined with pentagastrin secretory test and antral and fundic biopsy samples were taken for histological evaluation (the Sydney system). Blood samples were also taken for the determination of plasma gastrin using RIA and plasma interleukin (IL)-8 and tumor necrosis factor alpha (TNFalpha) using ELISA. This study was performed in 60 patients, 31-72 year old, with visible papules and pustules associated with erythema and flushing on the face and on 60 age- and gender-matched patients without any skin diseases but with similar as in rosacea gastrointestinal symptoms but without endoscopic changes in gastroduodenal mucosa (non-...

Treatment Of Rosacea With Intense Pulsed Light

Rosacea is a common skin condition but the treatments currently available are not satisfactory. OBJECTIVES: To assess the efficacy of intense pulsed light (IPL) for treatment of stage I rosacea (flushing, erythema and telangiectasia). METHODS: Thirty-four patients were treated, 25 women and nine men, mean age 47 years. The treatment employed was IPL 515-1200 nm, with a 560 nm cut-off filter. The fluence range was 24-32 J cm(-2). Four treatments were administered on the face at 3-week intervals. Erythema values were measured at baseline and at the end of the treatment period on the cheeks and chin. Digital photographs were assessed by a consultant dermatologist on a 10-point visual analogue scale (VAS). Patients' assessments were also made using a 10-point VAS. Outcome measures were repeated 6 months after treatment. RESULTS: After four treatments the mean reduction of the erythema values was 39% on the cheeks (P The severity of rosacea was reduced on average by 3.5 points on the 10...

Periorbital Dermatitis-- A Recalcitrant Disease

Periorbital dermatitis is common and frequently recalcitrant to treatment . Due to the exposed and visible location, patients often suffer severely from periorbital dermatitis. OBJECTIVES: To determine the frequency and causes of periorbital dermatitis including contact sensitizers. METHODS: We investigated two cohorts of patients (Erlangen and IVDK without Erlangen) between 1999 and 2004. RESULTS: The differences between the two cohorts with periorbital dermatitis [Department of Dermatology at University Hospital Erlangen (n = 88) and the German Information Network of Departments of Dermatology (IVDK) collective (n = 2035)] were determined by the MOAHLFA (male, occupational dermatosis, atopic eczema, hand dermatitis, leg dermatitis, facial dermatitis, age > or = 40 years) index. Statistically significant factors for periocular eczema are female sex, atopic skin diathesis and age > or = 40 years. In both cohorts allergic contact dermatitis was the main cause of periorbital eczema...
