Measurement of the severity of rosacea.

BACKGROUND: There are no standardized measures for the severity of rosacea. OBJECTIVES: To determine what clinical signs correlate best with global severity of rosacea, and to examine inter-rater reliability. Methods Four clinicians each made 82 assessments of rosacea patients. Each assessment used 60 0-to-10 Likert-like scales for the signs of rosacea. Subjects also assessed the severity of their rosacea. RESULTS: The clinicians' assessment of global severity correlated strongly with erythema, especially on the cheeks. Subjects' assessment of global severity correlated more strongly with papules/pustules. Different methods of assessing severity--estimation of area involved, intensity, or lesion counts--did not produce significantly different results. Inter-rater reliability was low on 11-point (0-10) scales, but improved when scales were collapsed to 5 or 4 points. CONCLUSIONS: Clinicians and patients assess severity of rosacea differently, with clinicians focusing on erythema and patients focusing on papules/pustules. New instruments for assessing severity must address inter-rater reliability.

Rosacea: current thoughts on origin.

Rosacea is a clinical pattern beginning and evolving in the genetically susceptible individual in response to a host of exposures. It produces a variety of clinical presentations, which vary over time and with age. Recently, many specific mediators of rosacea development have been described. A primary genetic cause for rosacea is suggested as single genes often control such mediators: enzymes, neuroendocrine transmitters, and cytokines are found in pathways to rosacea signs and symptoms. Currently, neither a specific cause nor a laboratory indicator of rosacea has been suggested. However, broadening interest in rosacea portends future increase in knowledge.

Tacrolimus ointment for the treatment of steroid-induced rosacea: a preliminary report.

BACKGROUND: Excessive topical corticosteroid application to facial areas commonly leads to steroid-induced rosacea. This may be a recalcitrant problem that requires months of antibiotic and anti-inflammatory therapy before it resolves. OBJECTIVE: The purpose of this article is to review the use of tacrolimus ointment, a macrolide anti-inflammatory ointment for the treatment of 3 patients with steroid-induced rosacea. METHODS: Three patients with steroid-induced rosacea applied tacrolimus ointment, 0.075% twice daily for 7 to 10 days. Patients were also instructed to avoid topical corticosteroid use and other rosacea-aggravating substances including caffeine, spicy foods, alcohol, hot fluids, and fluoride. Patients were observed for tenderness, erythema, and relief of pruritus. RESULTS: Pruritus, tenderness, and erythema were resolved in all 3 patients after 7 to 10 consecutive days' use of tacrolimus 0.075% ointment in conjunction with avoidance of topical steroids, caffeine, spicy food, alcohol, hot fluids, and fluoride. CONCLUSION: This preliminary study demonstrates that tacrolimus 0.075% ointment may be effective for patients with steroid-induced rosacea, when combined with avoidance of topical steroid use, as well as avoidance of other agents known to aggravate rosacea (caffeine, spicy foods, alcohol, hot fluids, and fluoride).

Efficiency of benzoyl peroxide-erythromycin gel in comparison with metronidazole gel in the treatment of acne rosacea.

Oral wide-spectrum antibiotics are the linchpin of rosacea treatment. Oral and topical metronidazole, topical tretinoin, and topical benzoyl peroxide may also be used in the treatment of rosacea. We aimed to show that benzoyl peroxide-erythromycin gel is efficient in the treatment of acne rosacea. Fifty-six patients with acne rosacea were enrolled in our study. We administered benzoyl peroxide-erythromycin gel to 27 patients and metronidazole gel to 29 patients. In all the patients, the intensities of erythema, telangiectasia, papules/pustules, and nodules were evaluated before, during and after the treatment. The positivity of Demodex folliculorum from skin scratches was compared between the two groups at each visit. At the end of the therapy on the third examination, in the benzoyl peroxide-erythromycin group, 91.7% of the patients showed marked clinical improvement, and 8.3% of them showed complete remission. In the metronidazole group, 73.3% showed marked clinical improvement, and 26.7% of them showed complete remission. Clinical improvement in the papular component was 65.2% for the benzoyl peroxide-erythromycin group, and 81.5% for metronidazole group. In the first examination, the clinical results of the agents were similar. Although both of the drugs were found to be effective in the second and third examinations, metronidazole gel was more effective than benzoyl peroxide-erythromycin. Both of the drugs were found to be significantly effective especially in treating the papular component of rosacea. Demodex folliculorum was found to be positive in 74.1% of the benzoyl peroxide-erythromycin group and in 62.1% of the metronidazole group at the beginning. In the benzoyl peroxide-erythromycin group, 40.7% of Demodex folliculorum positive patients, became negative by the first examination. This was 17.2% for the metronidazole group. In the benzoyl peroxide-erythromycin group, among the patients who were positive for Demodex folliculorum in the first examination, 37.5% of them became negative. This was 36.7% for the metronidazole group. Benzoyl peroxide-erythromycin gel was superior to metronidazole gel in decreasing Demodex folliculorum by the first examination, but the effect of the two drugs on Demodex folliculorum was similar by the second examination. As a result, topically applied combined benzoyl peroxide-erythromycin gel may be an alternative choice of treatment for acne rosacea.

Epithelial barrier function and atopic diathesis in rosacea and perioral dermatitis.

BACKGROUND: Rosacea and perioral dermatitis (PD) are common dermatoses, the aetiology and pathogenesis of which remain speculative. Objectives To investigate skin barrier function and features of atopy in both diseases. METHODS: We studied 75 patients with rosacea and 75 with PD. Transepidermal water loss (TEWL) was measured in three regions of the face (lateral chin, perinasal cheek, side of the nose) and the patients were assessed for atopy by clinical criteria, prick tests and specific IgE against a mixture of aeroallergens (CAP SX1). The control group consisted of 125 individuals with no history of rosacea, PD or active atopic disease. RESULTS: In patients with PD, TEWL was significantly increased (P < 0.001) at all measurement points in comparison with the rosacea and control groups. Significantly (P < 0.001) higher values were also found regarding history and clinical signs of an atopic diathesis, prick test reactivity and specific IgE against aeroallergens. CONCLUSIONS: PD is characterized by a skin barrier disorder of facial skin. It differs from rosacea in that it involves a significantly increased TEWL and features of an atopic diathesis. However, it remains disputed as to whether PD is an individual skin disease or a subtype of rosacea in atopic patients.

Double-blind, randomized, vehicle-controlled clinical trial of once-daily benzoyl peroxide/clindamycin topical gel in the treatment of patients with moderate to severe rosacea.

BACKGROUND: Systemic antibiotics such as tetracycline are well accepted as effective in treating the inflammatory papular/pustular phase of rosacea but may be associated with systemic side-effects. Few controlled data on the use of topical antibiotics in rosacea are available. OBJECTIVE: We evaluated the efficacy and tolerability of a fixed combination of 5% benzoyl peroxide and 1% clindamycin in a topical gel for the treatment of rosacea. Methods This was a 12-week, double-blind, vehicle-controlled, randomized, prospective, parallel-group study in 53 patients with moderate to severe rosacea. RESULTS: The mean percentage reduction in papules and pustules from baseline to the end of treatment was 71.3% in the benzoyl peroxide/clindamycin group (n = 26) and 19.3% in the vehicle group (n = 26; P = 0.0056). A significant (P = 0.0141) difference in favor of benzoyl peroxide/clindamycin was evident by the third week of treatment. Severity scores for erythema, papules/pustules, and flushing/blushing decreased more with benzoyl peroxide/clindamycin than with vehicle. Overall rosacea severity, Physician Global Assessment, and Patient's Global Assessment at the end of treatment were all significantly improved with benzoyl peroxide/clindamycin compared with vehicle (P = 0.0101, 0.0026, and 0.0002, respectively). Application site reactions were reported in four patients (14.8%) in the benzoyl peroxide/clindamycin group. CONCLUSION: A once-daily topical application of a combination of 5% benzoyl peroxide and 1% clindamycin is effective and well tolerated in patients with moderate to severe rosacea.

Randomized placebo-controlled trial of a flavonoid-rich plant extract-based cream in the treatment of rosacea.

BACKGROUND: Biological research suggests that vascular changes may play a major role in rosacea pathogenesis. Chrysanthellum indicum is a plant-based extract containing a unique combination of phenylpropenoic acids, flavonoids and saponosids, and has a well-documented effect on vascular wall permeability and increase of the mechanical resistance of capillaries. OBJECTIVE: To determine the efficacy and safety of a cream containing 1%C. indicum extract with vitamin P properties in the treatment of rosacea. METHODS: This study included 246 patients diagnosed clinically as having moderate rosacea. Patients were randomly allocated to C. indicum extract-based cream (n = 125) and placebo (n = 121) groups. Patients were advised to apply the products on their face twice a day for a 12-week period. The patients were examined at the end of each 4-week period. Severity of erythema (graded by reference to six photographs), surface of erythema and rosacea overall severity scores were recorded at each visit on days 0, 28, 56 and 84. Investigators carried out a final efficacy assessment at the end of week 12. Volunteers' final overall efficacy assessment was recorded in a self-administered questionnaire. Adverse events were identified through examination, interview and collection of comments in patients' questionnaires. RESULTS: Treatment with the C. indicum extract-based cream resulted in significant improvement (P < 0.05) in severity of erythema, overall rosacea severity compared to baseline and placebo, and investigator and patient overall efficacy assessment scores (P = 0.046 and P = 0.001, respectively) compared with placebo scores. Adverse reactions were mild, and did not differ between the C. indicum extract-based cream and the placebo groups. CONCLUSION: Chrysanthellum indicum extract-based cream is an effective and well-tolerated topical agent for the treatment of moderate rosacea. The mode of action of the active ingredient suggests that additional efficacy might be expected from combination with other topical treatments.

Effective treatment of rosacea using intense pulsed light systems.

BACKGROUND: To date, a variety of lasers have been used for treating vascular skin lesions. Intense pulsed light (IPL) is a proven technology for vascular lesion management, such as rosacea. OBJECTIVES: The aim of this study was to test the effectiveness of IPL in treating vascular facial lesions in rosacea patients. METHODS: Sixty patients presenting with telangiectasia owing to facial rosacea were selected randomly from the patient population in the Department of Laser Therapy at the Medical Centre Maastricht, the Netherlands. Patients of various skin types (Fitzpatrick I-IV) were selected with an average age of 44.2 years. Five hundred eight sites were treated, with a mean of 4.1 treatments per site and an IPL spectrum ranging from 515 to 1,200 nm with different pulse durations between 4.3 and 6.5 milliseconds. The energy density varied from 25 to 35 J/cm2. RESULTS: Patients were assessed clinically and photographically. A mean clearance of 77.8% was achieved and was maintained for a follow-up period averaging 51.6 months (range 12-99 months). No correlation was found between the clearance of rosacea and patient-related or technical data. For approximately 3 years post-treatment, lesion recurrence was noted in 4 of the 508 treated facial sites. DISCUSSION: This study demonstrated that IPL treatment of facial rosacea is effective in obtaining clearance of 77.8%, with minimal side effects, and that treatment effects are maintained. CONCLUSION: The IPL system, with its broad range of technical variables, is an effective tool in achieving meaningful and lasting rosacea clearance.

Rosacea: a clinicopathological approach.

BACKGROUND: There are few reports of the histological changes in rosacea, and little attempt has been made to correlate such changes with clinical findings. In the present study, we describe in detail the histopathological features of rosacea in a large number of patients and simultaneously investigate the aetiopathogenesis of the disease based on the comparative assessment of epidemiological, clinical and histological findings. METHODS: The study included 73 patients with rosacea. A skin biopsy with a 4-mm punch was performed in each case. All biopsy specimens included subcutaneous tissue. In 10 randomly selected patients, facial biopsy specimens were obtained from both involved and uninvolved (non-lesional) skin. Demodex mite presence was estimated semi-quantitatively under light microscopy. Patients with self-reported gastro-intestinal symptoms were submitted to upper gastro-intestinal endoscopy, and a rapid urease test was performed. Serological antibodies, IgG and IgA, against Helicobacter pylori were also detected. RESULTS: The patients had a broad clinical spectrum of lesions. No specific histological features associated with either erythematous-telangiectatic or papulopustular clinical forms were noticed. Histological examination showed that there is no histological pattern unique to rosacea. Three different types of granulomas were observed: small palisaded ones around altered collagen and other granulomas of elastolytic and non-specific epithelioid type, all coexisting in 5 cases. The deep dermis and subcutis were frequently involved. Comparative study in 10 rosacea patients between lesional and non-lesional skin biopsies revealed almost the same histological changes to the latter biopsies, to a lesser degree though. CONCLUSION: Rosacea seems to be a reaction pattern to which a variety of pathogenetic routes may lead.

Medical treatment of rosacea with emphasis on topical therapies.

Due to the development and release of newer topical formulations, the diagnosis and treatment of rosacea has received renewed attention over the past 3-5 years both in the literature and at medical symposia. Rosacea is a very common facial dermatosis. In the US, rosacea is estimated to affect > 14 million people, predominantly adults with approximately 60% of cases diagnosed before the age of 50. A frustrating aspect of the disease is its inherent chronicity punctuated with periods of exacerbation and relative remission. A variety of subtypes have been identified which correlate with clinical presentation. Although the pathogenesis of rosacea is poorly understood, multiple topical agents are available. The efficacy of topical therapy for rosacea relates primarily to reduction in inflammatory lesions (papules, pustules), decreased intensity of erythema, a reduction in the number and intensity of flares and amelioration of symptoms, which may include stinging, pruritus and burning. The list of main topical agents utilised for the treatment of rosacea include metronidazole, sulfacetamide-sulfur, azelaic acid and topical antibiotics (clindamycin, erythromycin). Depending on the severity at initial presentation, topical therapy may be combined with systemic antibiotic therapy (e.g., oral tetracycline derivative). Newer therapeutic choices primarily involve improved vehicle formulations, which demonstrate favourable skin tolerability and cosmetic elegance.

Relationship between Helicobacter pylori and rosacea: it may be a myth.

Although it is debatable whether Helicobacter pylori may play a role in the pathogenesis of rosacea, some authors suggested that the treatment of H. pylori might have a beneficial effect. The aim of this investigation was to compare the prevalence of H. pylori between rosacea patients and controls, and to evaluate an effect of H. pylori eradication on rosecea by a 2-week triple therapy that was composed of amoxicillin, clarithromycin and omeprazole. H. pylori was detected by using gastroscopic biopsy with Warthin-Starry stain. Forty-two (84%) of 50 patients with rosacea and 39 (78%) of 50 controls had H. pylori, showing no significant difference in prevalence. The cure rates of H. pylori in rosacea patients and controls were 80% (16/20) and 85% (17/20), respectively. There was no significant decrease in the intensity of erythema in active treatment and placebo groups both during and after the treatment. Temporary improvement in papulopustules exclusively during the treatment (within 2 weeks) could be independent of H. pylori eradication. Overall, no significant reduction in the number of papulopustules was observed in active treatment and placebo groups after the treatment (in 2 months). Taken together, our study found no significant lessening of rosacea lesions by treating H. pylori infection, which conclusively does not concur with a view that H. pylori may be related to rosacea.

Tear lactoferrin levels in chronic meibomitis associated with acne rosacea.

PURPOSE: To determine tear lactoferrin levels in patients with chronic diffuse meibomitis associated with acne rosacea and to investigate their role in the development and perpetuation of some inflammatory ocular surface complications. METHODS: In this non-randomized, controlled trial performed in a tertiary care center, eight patients with biopsy-proven acne rosacea and blepharitis, and ten patients with seborrheic blepharitis not associated with acne rosacea formed the study groups and ten normal patients were used as controls. Schirmer I test results, tear break-up time and radial immunodiffusion (Lactoplate) tests on tear samples of the three groups were compared. RESULTS: Compared to controls, tear lactoferrin concentrations were lower in both the acne rosacea and seborrheic blepharitis groups. However, this decrease was significant in only the seborrheic blepharitis group (p = 0.026). One patient in the acne rosacea group, with the lowest measurement, developed bacterial keratitis. CONCLUSIONS: Though within the normal range, tear lactoferrin levels in patients with acne rosacea and seborrheic blepharitis were lower than controls. Low concentrations of lactoferrin may play a role in the ocular surface inflammatory components associated with these diseases.

Women commonly seek care for rosacea: dermatologists frequently provide the care.

Rosacea is a common dermatosis affecting the central portion of the face. The purpose of this study is to describe the demographics of patients and the treatments prescribed. Data on rosacea visits from 1990 to 1997 were obtained from the National Ambulatory Medical Care Survey There were 1.1 million outpatient visits for rosacea annually in the United States. Most rosacea patients were Caucasian (96%). Most visits were by women (69%), and the mean age (SD) of patients was 50 +/- 17 years. Visits to dermatologists accounted for 78% of visits. Common comorbid diagnoses included actinic keratoses, acne and cysts, and seborrheic and contact dermatitis. Topical metronidazole was the most commonly prescribed treatment; tetracycline was the most commonly prescribed systemic therapy. Combination treatment with an oral and a topical agent was commonly used. Because rosacea appears most often in fair-skinned women, these patients may benefit from the textural features and safety profiles of certain topical metronidazole preparations newly available and from oral antibiotics (eg, tetracycline). People with rosacea should be aware of the experience that dermatologists have in treating this disorder.

Etiopathogenesis, classification, and current trends in treatment of rosacea.

Rosacea is a common chronic dermatosis characterized by varying degrees of flushing, erythema, telangiectasia, edema, papules, pustules, ocular lesions, and phymas. Etiology and pathogenesis of rosacea are still unknown. Many possible causes have been described as inducing the disease or contributing to its manifestation, such as genetic predisposition, abnormal vascular reactivity, changes in vascular mediating mechanisms, Helicobacter pylori infection, Demodex folliculorum infestation, seborrhea, sunlight, hypertension, and psychogenic factors. However, none of these factors has been proved. Rosacea shows a wide spectrum of clinical presentations, which vary over time and with age. Successful management of rosacea requires careful patient evaluation and individualized therapy with appropriate variations and modifications, as the severity of the disorder fluctuates. In mild cases of rosacea, patients are instructed to avoid sun, to apply sun-protective creams, and to avoid facial irritants and other triggers that provoke symptoms. At later stage, drug therapy is often necessary. The disease commonly requires long-term treatment with topical or oral medicaments. Surgical correction may be required for rhinophyma and telangiectasia. We reviewed the current literature on the aspects of the pathogenesis, diagnostic criteria, and treatment options for rosacea.

[Rosacea as a multisystemic disease].

Rosacea is a chronic skin disorder, affecting the face and chest, and develops mostly in the 3rd to 6th decades of life. It is characterized by erythema, telangiectasias, and recurrent flushings. During the time of this chronic inflammation, skin typically develops papules, pustules, and swelling. Ocular involvement occurs in 3 to 58% of patients with skin changes. Common ocular signs include blepharoconjunctivitis, meibomitis, and dry eyes. Rosacea keratitis, when present, however, has a poor prognosis and may lead to blindness. Among skin diseases, Helicobacter pylori infection has been often related with rosacea. A higher prevalence of indigestion and Helicobacter pylori infection in rosacea patients than in healthy controls has been reported. However, no causal relation has been identified. On the other hand, oral treatment with metronidazole is beneficial in all of three mentioned manifestations of rosacea (skin, eye, indigestion). There is obvious need for multidisciplinary approach, and investigation to rosacea.

Rosacea, light, and phototherapy.

The long-established notion that rosacea is worsened by light is of particular concern in the phototherapy of diseases such as psoriasis, eczema, or vitiligo, which often can be coexistent with rosacea. A literature search was conducted and much evidence was found to challenge this belief that light adversely affects rosacea. In fact, more patients actually improved with sunlight in a more recent published survey. Several other studies have also shown that rosacea patients were similar to control subjects in sun exposure, solar skin damage, and sun sensitivity. Additionally, all clinical trials to date have failed to find a difference between rosacea patients and control subjects when challenged with ultraviolet light. Thus, phototherapy with rosacea may be safer than is commonly believed.

The face and mind evaluation study: an examination of the efficacy of rosacea treatment using physician ratings and patients' self-reported quality of life.

OBJECTIVE: To examine both the short-term clinical efficacy and quality-of-life changes resulting from treatment of rosacea with regimens that reflect the participating physicians' standards of care while incorporating azelaic acid gel. DESIGN: Longitudinal, open-label, observational study. PATIENTS: 583 patients with mild to moderate rosacea participated in this study. INTERVENTIONS: Patients received azelaic acid gel either alone or in combination with other standard treatment for rosacea according to each participating physician's standards of care. MAIN OUTCOME MEASURES: Change in Investigator's Global Assessment score, measuring the severity of rosacea symptoms, from baseline to follow-up, and change in scores on the RosaQoL, a rosacea-related quality-of-life instrument with 4 component measures (Overall, Emotion, Symptom, and Function) completed by patients at both baseline and follow-up. RESULTS: Over the course of treatment, the mean Investigator's Global Assessment score dropped from 3.52 to 2.10 (P < .0001). Patients who were prescribed combination therapy had significantly greater improvement than those who were prescribed azelaic acid gel alone (P < .0001). All 4 components of the RosaQoL also showed significant improvement over the course of treatment, regardless of the type of therapy prescribed (P < .0001). CONCLUSION: Azelaic acid gel, either alone or in combination with other medications, is efficacious in the treatment of mild to moderate rosacea, as shown by observational data collected in the clinical setting from both treating physicians and patients.

Topical therapies for rosacea.

Therapeutic options for rosacea include topical agents, oral therapies, laser and light treatments, and surgical procedures. Topical therapies play a critical role in the treatment of patients with papulopustular rosacea and erythematotelangiectatic rosacea, and have the ability to effectively minimize certain manifestations of the disease, including papules, pustules, and erythema. The 3 primary agents for the topical treatment of rosacea are metronidazole, azelaic acid, and sodium sulfacetamide-sulfur. Each of these therapies is approved for the treatment of rosacea and has been validated by multiple studies. Additional topical therapies including benzoyl peroxide, clindamycin, retinoids, topical steroids, calcineurin inhibitors, and permethrin are not approved for the treatment of rosacea and play variable roles in the management of this condition.
