Assessment of thyroid disorders in patients with rosacea: a large case-control study

Abstract Background: The frequency of autoimmune diseases and thyroid cancer has been increasingly reported in association with rosacea. However, studies investigating thyroid diseases in rosacea are scarce with conflicting results. Objective: To investigate the relationship between thyroid disorders and rosacea. Methods: A large case-control study on ageand gender-matched 2091 rosacea patients and 9572 controls was conducted. Rosacea patients using the rosacea-specific ICD codes were compiled from the hospital records. Additionally, all participants were evaluated in terms of the presence of hypothyroidism and hyperthyroidism. Conditional logistic regression analysis was used to compute case-control odds ratios (OR) with 95% confidence intervals. Results: The analysis comprehended 2091 rosacea patients (1546 female, 545 male; mean 48.73 ± 14.53 years) and 9572 controls (7009 female, 2563 male; mean 48.73 ± 15.1 years). Whereas the rate of hypothyroidism was significantly higher in rosacea patients (OR = 1.3, 95% CI 1.13-1.49, p < 0.001), there was no significant difference in the rate of hyperthyroidism between the groups (OR = 1.12, 95% CI 0.81-1.53, p = 0.497). Stratification for gender revealed a significant association between hypothyroidism and rosacea in females (OR = 1.27, 95% CI 1.1-1.47, p = 0.002) and males (OR = 1.58, 95% CI 1.04-2.4, p = 0.032). The frequency of hypothyroidism in rosacea patients increased towards the age range of 40-49 and then decreased, parallel with the hypothyroidism frequency of the study population. Study limitations: Different subtypes and severities of rosacea were not distinguished. Conclusions: Hypothyroidism may be a comorbidity of rosacea and investigation for hypothyroidism may be appropriate when evaluating rosacea patients.

Rosacea associated with increased risk of generalized anxiety disorder: a case-control study of prevalence and risk of anxiety in patients with rosacea

Abstract Background: Rosacea may result in emotional distress and anxiety. However, data on the presence of generalized anxiety disorder in rosacea patients are scarce. Objective: The aim of the study was to detect the frequency and level of anxiety and depression in patients with rosacea. Methods: A total of 194 consecutive rosacea patients and 194 age- and sex-matched controls were enrolled. Severity of rosacea was assessed in patients according to the criteria of the National Rosacea Society Ethics Committee. Both patients and controls were evaluated by the Generalized Anxiety Disorder 7-item scale, and severity was measured by the Generalized Anxiety Disorder-Adult. Results: Individuals who were diagnosed with an anxiety and/or depressive disorder were more common in patient group (24.7% vs. 7.2%, p < 0,01). Female patients were particularly at risk for having generalized anxiety disorder (OR = 2.8; 95% CI 1.15-7.37; p = 0.02). Study limitations: Single center study and limited sample size. Conclusions: Rosacea patients show greater risk of having anxiety disorders, including generalized anxiety disorder. Female patients, those with lower educational levels, those with phymatous subtype, untreated patients, and patients with prior psychiatric morbidity may be at particular risk for anxiety. It is essential to consider the psychological characteristics of patients to improve their well-being.

Morbihan disease: a therapeutic challenge

Abstract: Morbihan disease is a rare condition characterized by chronic and persistent erythematous solid edema localized on the face. It is believed to be a complication of rosacea and may occur at any stage of the disease. Features of this condition include variable therapeutic response and great refractoriness. We report a case of a 61-year-old man with rosacea history diagnosed with Morbihan disease, who showed excellent therapeutic response with the combination of deflazacort and oral isotretinoin but developed recurrence after corticosteroid discontinuation. We believe that in severe cases of lymphedema of the face this combination is effective and corticosteroid suspension should be done slowly and gradually.

Thickness of carotid intima and epicardial fat in rosacea: a cross-sectional study

Abstract: Background: Rosacea is a chronic facial skin disease associated with excessive inflammatory response to various triggers. Although some studies have supported the increased risk of cardiovascular diseases in rosacea, it has not been completely accepted. Objective: We aimed to investigate epicardial fat thickness and carotid intima-media thickness as cardiovascular risk predictors in rosacea patients. Methods: We conducted a cross-sectional study including 40 rosacea patients and 40 controls. Demographic data, epicardial fat thickness, carotid intima-media thickness, lipid parameters, biochemical parameters, presence of insulin resistance, and presence of metabolic syndrome of the participants were recorded. Results: Forty rosacea patients (31 female and 9 male) and 40 controls (30 female and 10 male) were enrolled in the study. Rosacea patients had significantly higher epicardial fat thickness and carotid intima-media thickness volumes than controls (P<0.001). In the multivariate logistic regression analysis, epicardial fat thickness was independently related to presence of rosacea (P<0.001, OR=13.31). In the multiple linear regression analysis, the epicardial fat thickness was independently associated with rosacea (β= 0.47, P<0.001), carotid intima-media thickness (β= 0.36, P<0.001), and systolic blood pressure (β=0.19, P=0.015) and the carotid intima-media thickness was independently associated with epicardial fat thickness (β= 0.6, P<0.001). The epicardial fat thickness levels were correlated with carotid intima-media thickness (r=0.63, P<0.001), LDL (r=0.23, P=0.037), systolic blood pressure (r=0.45, P<0.001), and diastolic blood pressure levels (r=0.37, P=0.001). The carotid intima-media thickness levels were correlated with epicardial fat thickness (r=0.63, P<0.001), systolic blood pressure (r=0.04, P<0.001), and diastolic blood pressure levels (r=0.27, P=0.016). Study limitations: The small number of participants. Conclusions: Examination and follow-up of rosacea patients for cardiovascular diseases may be recommended practices.

Timolol tópico en el tratamiento de rosácea eritematotelangiectásica: ensayo clínico randomizado doble ciego / Topical timolol in the treatment of erythematotelangiectatic rosacea: double blind randomized clinical trial

Introducción: La rosácea es un síndrome inflamatorio crónico frecuente que afecta principalmente la zona centrofacial. El subtipo más común, la rosácea eritematotelangiectásica (RET), no cuenta con un tratamiento efectivo demostrado. Estudios in vitro han propuesto que el factor de crecimiento endotelial (VEGF) podría tener un rol clave en la génesis de la rosácea al inducir angiogénesis. El uso exitoso de betabloqueadores orales (propanolol) y tópicos (timolol) en el hemangioma de la infancia abrió las puertas al estudio de la inhibición de la angiogénesis como principal objetivo terapéutico de las patologías vasculares benignas. Debido a que este subtipo de rosácea y los hemangiomas podrían presentar una etiopatogenia similar, se propone el estudio del efecto del timolol en este subtipo de rosácea. Metodología: Ensayo clínico randomizado doble ciego. Se reclutaron 67 pacientes con RET desde septiembre a diciembre de 2011. Se asignó un grupo con timolol tópico al 1 por ciento en base oil free y otro sólo con base oil free. Todos los pacientes recibieron instrucción y tratamiento estándar consistente en un limpiador, hidratante y protector solar. Nuestro outcome primario fue la diferencia de reducción del grado de eritema a las 12 semanas con colorímetro CR 200 de Minolta, y fue analizado según intención de tratar. Se evaluaron además las diferencias en las características clínicas, demográficas, el tamaño de las telangiectasias, la calidad de vida, evaluación subjetiva del tratamiento por el paciente, la adherencia a tratamiento y las reacciones adversas. Resultados: No hubo diferencia significativa en el grado de eritema a las 12 semanas de tratamiento entre los grupos, lo que permite rechazar la hipótesis diagnóstica. Tampoco se encontró diferencia alguna en los otros parámetros estudiados.

Introduction: Rosacea is a common chronic inflammatory syndrome that mainly affects the midface area. The most common subtype, Erythematotelangiectatic rosacea (ETR) has no proven effective treatment. Studies in vitro have suggested that vascular endothelial growth factor (VEGF) may have a key role in the pathogenesis of rosacea inducing angiogenesis. The successful use of oral (propanolol) and topical (timolol) betablockers in the childhood hemangioma conducted to the study of inhibition of angiogenesis as a main therapeutic target of benign vascular pathologies. Because this subtype of rosacea and hemangiomas share a similar pathogenesis, we proposed to study the effect of timolol in this subtype of rosacea. Methodology: Double blind randomized clinical trial. We recruited 67 patients with ETR from September to December of 2011. Two groups were assigned one with 1percent topical timolol oil free based and the other group used only the vehicle. All patients also received education and standard treatment consisting of a cleanser, moisturizer and sunscreen. The primary outcome was the difference in reducing the degree of erythema at week 12, and was evaluated through the Minolta CR 200 colorimeter and analyzed by intention to treat. Secondary outcomes were differences in clinical and demographic characteristics of the patients, the size of telangiectasias, quality of life, subjective evaluation from the patient, adherence to treatment and adverse reactions. Results: No significant difference was seen in the reduction of erythema degree at week 12 allowing us to reject the hypothesis. There were also no difference in all the other parameters. Conclusion: The present study shows that the use of topical timolol its not superior to placebo in reducing the degree of erythema or any of the variables analyzed. This study shows that topical timolol not constitute a possible treatment in ETR.

Spontaneous corneal perforation in ocular rosacea

Rosacea is a dermatologic condition that affects the midfacial region. Ocular rosacea is most frequently diagnosed when cutaneous signs and symptoms are also present. Ocular manifestations are essentially confined to the eyelids and ocular surface. Ocular involvement ranges from minor irritation, dryness, and blurry vision to potentially severe ocular surface disruption including corneal ulcers, vascularization and rarely perforation. We present a 49'year-old Saudi Arabian female with the diagnosis of rosacea who presented with a peripheral corneal performation. The perforation was successfully managed by surgical repair, oral doxycycline and topical steroid. The final best corrected visual acuity was 20/30 after treatment. Early referral to an ophthalmologist and careful long-term followup are recommended

Estudio de compromiso ocular en pacientes con rosácea / Ocular involvement in patients with cutaneous rosacea

La rosácea cutánea (RC) es una enfermedad crónica relativamente común que puede presentarse con afectación ocular. La rosácea ocular es considerada una enfermedad bilateral, manifestándose en la mayoría de los casos en forma simultánea al compromiso cutáneo. El objetivo del estudio es determinar el compromiso ocular de pacientes portadores de RC comparados con un grupo control y la asociación de severidad entre el compromiso cutáneo y el ocular. Se analizó un total de 112 pacientes; un primer grupo de 70 pacientes portadores de RC en un período de dos años, y el segundo constituido por 42 controles sanos. Observamos que en nuestros pacientes con RC hay una alteración de la función lagrimal y no existe relación estadísticamente significativa entre la severidad del compromiso cutáneo y el compromiso ocular. Debido a que el compromiso ocular en la RC es subestimado, es importante la evaluación de síntomas oculares en los pacientes con RC para continuar un manejo bidisciplinario entre dermatólogos y oftalmólogos.

Cutaneous rosacea (CR) is a relatively common chronic disease that can occur with ocular involvement. Ocular rosacea is considered a bilateral entity that usually manifests simultaneously with cutaneous disease. The objective of this study is to determine ocular involvement in CR patients, compared with a control group, and to establish the association between severity of cutaneous and ocular involvement. 112 patients were analyzed; a first group of 70 patients with a two year story of CR, and the second group consisting of 42 healthy controls. At the end of the study, we observed that patients with CR had tear dysfunction and there was no statistically significant relationship between the severity of cutaneous and ocular involvement. Since eye involvement in CR is underestimated, we consider it important to investigate ocular symptoms in patients with CR and maintain multi-disciplinary management between dermatologists and ophthalmologists.

Rosácea ocular: un diagnóstico a menudo no considerado en rosácea / Ocular rosacea: a diagnostic frequently non-considered in rosacea

La rosácea es una enfermedad crónica que puede asociarse e incluso debutar con un compromiso ocular (rosácea ocular), siendo ésta principalmente de predominio palpebral (blefaritis), conjuntiva y/o corneal, es decir, fundamentalmente del polo anterior del ojo. Se presume multifactorial, siendo la alteración de la composición del componente lipídico de la lágrima, motivada por lipasas estafilocócicas aumentadas y meibomitis, los eventos precursores más ampliamente aceptados. Actualmente el tratamiento se basa en fotoprotección ocular, uso de lágrimas artificiales y antibioticoterapia oral y tópica. Otras alternativas de segunda línea son el metronidazol, isotretinoína tópica y sistémica, cirugía y oclusión del punto lacrimal.

Rosácea con compromiso ocular en la niñez / Rosacea with ocular involvement in childhood

La rosácea ocular es una dermatosis facial, frecuente en adultos, especialmente mujeres, cuya fisiopatología es aún mal comprendida, aunque parece relacionada a cambios vasomotores. La afección es infrecuente en niños y adolescentes, donde plantea probremas diagnósticos y terapéuticos. Presentamos un caso de rosácea infantil con compromiso ocular. La rosácea ocular se manifiesta con hiperhemia conjuntival, telangiectasias, meibomitis, chalazion, blefaritis, queratoconjuntivitis, vascularización corneal periférica e infiltración subepitelial, iritis y queratitis en los casos mas severos; el hallazgo más frecuente perece ser una blefaritis marginal
