Symptomatic treatment of idiopathic and rosacea-associated cutaneous flushing with propranolol

Flushing has been associated with medications, rosacea, menopause, carcinoid syndrome, pheochromocytoma, polycythemia, and mastocytosis, although it can occur without known cause. There are no known specific treatments available, but beta-blockers have suppressed flushing reactions in some patients, particularly when associated with anxiety. The medical histories and clinical characteristics of 9 patients with either idiopathic flushing or flushing associated with rosacea were reviewed. Eight patients experienced subjective improvement with propranolol therapy.     

中国玫瑰痤疮临床特征分析和诊断标准再探讨

【摘要】 目的 在分析玫瑰痤疮临床特征的基础上,提出中国玫瑰痤疮诊断标准并验证其敏感性和特异性。方法 纳入2017年12月至2018年7月于中南大学湘雅医院皮肤科门诊初诊的3 350例玫瑰痤疮患者,分析患者表型及临床特征,提出改良版中国玫瑰痤疮诊断标准。全国28个中心对该标准进行临床验证,纳入2 269例玫瑰痤疮和2 408例其他面部皮肤病患者,与2017版美国国家玫瑰痤疮专家委员会（NRSEC）制订的国际诊断标准比较,评估其敏感性和特异性。结果 3 350例玫瑰痤疮患者均存在面中部持续性红斑（100%）。在1 861例主要表现为面颊部红斑的患者中,1 850例（99.4%）在红斑之前或同时出现阵发性潮红;在1 489例主要表现为鼻或口周部红斑的患者中,仅52例（3.5%）发生阵发性潮红; 342例有肥大增生的患者均在肥大增生改变之前发生持续性红斑。基于以上临床特征提出,面颊部可周期性加重的伴有阵发性潮红的持续性红斑,可诊断为玫瑰痤疮;对于表现为鼻、口周部持续性红斑的患者,需合并至少1项选择性表型（阵发性潮红、毛细血管扩张、丘疹脓疱、肥大增生改变或眼部症状）才可诊断为玫瑰痤疮。全国多中心临床验证结果显示,改良版中国玫瑰痤疮诊断标准敏感性为99.6%,接近国际标准100%,特异性为91.9%,而国际标准为73.3%。结论 改良版中国玫瑰痤疮诊断标准具有良好的敏感性和特异性,也更有利于增生肥大型玫瑰痤疮的早期诊断。     

玫瑰痤疮面部潮红与红斑新认识

【摘要】 持续型面中部红斑与潮红是玫瑰痤疮最常见的临床表现,但对其病理机制了解甚少,并缺乏高证据等级临床研究支持。本文结合国内外研究进展及临床经验,强调将面部潮红与红斑作为独立的临床表型进行研究探讨的必要性,认为精神压力、焦虑和/或抑郁可能是其发病的使动环节。由精神因素出发,探索玫瑰痤疮面部潮红及红斑相关神经炎症与皮肤免疫及血管的关系具有潜在的临床意义。     

玫瑰痤疮患者阵发性潮红的临床特征分析及对生活质量的影响

【摘要】 目的 探讨玫瑰痤疮患者阵发性潮红的临床特点及对生活质量的影响。方法 采用前瞻性研究，收集2017年8月至2019年8月湘雅医院皮肤科门诊玫瑰痤疮患者728例，采用阵发性潮红国际标准化量表（FSQ）、持久性红斑医生评分量表（CEA）、患者自评量表（PSA）和视觉模拟评分法（VAS）收集资料，分析阵发性潮红的发作特点、严重程度、对生活的困扰度及其与持久性红斑评分的相关性等。统计分析采用χ2检验和Spearman相关分析。结果 728例患者中，阵发性潮红最常出现的部位为颊部（682例，93.7%）及颧部（617例，84.8%）；持续时间5 min至2 h的患者比例最高（484例，66.5%）；317例（43.6%）受刺激后潮红发作，233例（32.0%）潮红每天发作且1天内多次发作。503例（69.1%）患者潮红的总体评分在中度以上；412例（56.6%）认为潮红可对睡眠造成不同程度的影响，其中59例（8.1%）认为影响可达重度及以上；662例（90.9%）认为潮红对生活有不同程度的影响，其中304例（41.8%）认为影响程度在重度及以上。潮红总体评分和其对生活的困扰评分均与医生评价的持久性红斑严重程度（CEA评分）呈低度正相关（rs = 0.166、0.151，均P＜0.05），与患者自评的红斑严重程度（PSA评分）具有显著相关性（rs = 0.518、0.500，均P＜0.05）。结论 玫瑰痤疮患者的阵发性潮红具有典型的发作部位，发作持续时间较长，频率高，影响患者生活质量，需得到临床医生的重视。     

The management of rosacea

Rosacea is a multiphasic disease which is associated with flushing, erythrosis, papulopustular rosacea and phymas; each phase is likely to have its own treatment. Flushing is better prevented rather than treated, and its etiology investigated. Beta-blockers, atenolol in particular, are worthy of prophylactic trials examining their efficacy in treating the flushing associated with rosacea. Currently, clonidine is the only drug available for the treatment of flushing. Treatment for erythrosis includes topical and systemic therapies. Metronidazole 1% cream and azelaic acid 20% cream have been reported to reduce the severity score of erythema. The systemic treatment of erythrosis is based on the association of Helicobacter pylori with rosacea. However, this role is still being debated. Eradication of H. pylori can be achieved using a triple therapy regimen lasting 1 to 2 weeks [omeprazole and a combination of two antibacterials (a choice from clarithromycin, metronidazole or amoxicillin)]. Both the flashlamp-pumped long-pulse dye laser and the potassium-titanyl-phosphate laser may be used in the treatment of facial telangiectases. Both systemic and topical remedies may be used to treat the papulopustules of rosacea. Systemic treatment includes metronidazole, doxycycline, minocycline, clarithromycin and isotretinoin, while topical treatment is based on metronidazole cream and gel. The presence of Demodex folliculorum is important in the inflammatory reaction, whether it is pathogenetic or not. Crotamiton 10% cream or permethrin 5% cream may be useful medications for papulopustular rosacea, although they are rarely successful in eradicating D. folliculorum. Oral or topical ivermectin may also be useful in such cases. Ocular involvement is common in patients with cutaneous rosacea and can be treated with orally administered or topical antibacterials. Once rhinophyma starts to be evident, the only way to correct it is by aggressive dermatosurgical procedures. Decortication and various types of lasers can also be used. Associated conditions, such as seborrheic dermatitis and possible contact sensitizations, deserve attention.

Flushing: causes, investigation and clinical consequences

Flushing can occur as a physiological response or may indicate an underlying condition, such as carcinoid syndrome, mastocytosis or rosacea. The mechanisms and causes of flushing are discussed.   Learning objective
At the conclusion of this learning activity, participants should be able to describe the pathogenesis and clinical characteristics of flushing and should be aware of the modalities to diagnose and treat this common dermatological sign.     

Remission of rosacea induced by reduction of gut transit time

Rosacea is a chronic disorder characterized by hypersensitivity of the facial vasculature, presenting with intense flushing eventually leading to chronic erythema and telangiectasia. Although the precise aetiology of rosacea is not known, numerous associations with inflammatory gastrointestinal tract disorders have been reported. Furthermore, substance P-immunoreactive neurones occur in considerably greater numbers in tissue surrounding affected blood vessels suggesting involvement of neurogenic inflammation and moreover plasma kallikrein-kinin activation is consistently found in patients. In this report, a patient without digestive tract disease is described, who experienced complete remission of rosacea symptoms following ingestion of a material intended to sweep through the digestive tract and reduce transit time below 30 h. It is possible that intestinal bacteria are capable of plasma kallikrein-kinin activation and that flushing symptoms and the development of other characteristic features of rosacea result from frequent episodes of neurogenic inflammation caused by bradykinin-induced hypersensitization of facial afferent neurones. The possible relevance of this hypothesis to other conditions featuring afferent hypersensitivity, such as fibromyalgia, is considered.     

红黄光治疗急性肿胀期玫瑰痤疮疗效观察

 目的: 探讨红黄光治疗急性肿胀期玫瑰痤疮的治疗效果。 方法：回顾分析2018年3月至2019年6月在中南大学湘雅医院皮肤科门诊的30例急性肿胀期玫瑰痤疮患者的治疗效果,所有患者均给予红黄光（1次/d,连续3 d）治疗,评估治疗3 d后的疗效以及不良反应。 结果： 治疗3 d后,患者皮肤潮红（2.37±1.10）及肿胀（1.30±0.75）评分均较治疗前（分别为2.80±0.99、1.93±0.74）明显下降,差异具有统计学意义（t值分别为2.77、4.29,P＜0.05）;治疗有效率达70.00%;治疗者满意率达86.66%;治疗期间未见明显不良反应。 结论： 红黄光治疗对于缓解急性肿胀期玫瑰痤疮患者面部潮红肿胀疗效确切,起效快,不良反应少。     

Endothelial and axon reflex vasodilatation to acetylcholine in rosacea-affected skin

Rosacea is a chronic skin disorder, characterized by persistent painful facial flushing and often accompanied by papules and pustules. To investigate the mechanism of facial flushing in rosacea, acetylcholine was administered by iontophoresis to a 10-mm diameter site in the forehead of 31 patients with rosacea and in 29 controls of similar age and sex distribution. During the iontophoresis, current strengths doubled in eight steps from 2.5 to 320 μA. For each step, skin blood flow was monitored during 60 s of iontophoresis and for 2 min afterwards with laser Doppler flow probes at the site of iontophoresis and 5–8 mm away in the region of axon reflex vasodilatation. Vascular responses to acetylcholine were similar in patients and controls, but stinging sensations were greater in patients than in controls at the most intense current strength. In addition, axon reflex vasodilatation was greater in patients with severe than mild rosacea. These findings suggest that activation of nociceptive nerve fibres contributes to skin sensitivity in patients with rosacea, and that axon reflexes augment flushing in patients with the most severe symptoms.

Treatment of early-stage erythematotelangiectatic rosacea with a Q-switched 595-nm Nd:YAG laser

Erythematotelangiectatic rosacea presents as persistent erythema and telangiectasia with frequent flushing and blushing on the facial and extrafacial skin. Additionally, papulopustular rosacea shows acneiform papules, pustules, and nodules with persistent plaque-form edema. Despite garnering only grade-C or -D level recommendations, a 585-nm or 595-nm flashlamp-pumped pulsed-dye laser can be considered as an effective therapeutic modality for the treatment of rosacea in patients who are refractory to topical and/or systemic treatments. In this report, treatment with a Q-switched 595-nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser with low non-purpuragenic fluence proved to be safe and effective in treating early-stage erythematotelangiectatic rosacea in two female Korean patients. Laser treatment for rosacea was delivered with the settings of pulse energy of 0.4–0.5 J/cm², pulse duration of 5–10 ns, 5-mm spot size, 5 Hz, and 500 shots. Additionally, we found that remarkable therapeutic effects were achieved for both rosacea and melasma by combining Q-switched quick pulse-to-pulse 1,064-nm Nd:YAG and Q-switched 595-nm Nd:YAG laser treatments, which required only the changing of handpieces equipped with solid dye. In conclusion, we suggest that treatment with a Q-switched 595-nm Nd:YAG laser with low fluence may provide an additional therapeutic option for treating early-stage erythematotelangiectatic rosacea.     

Ocular rosacea and treatment of symptomatic Helicobacter pylori infection: a case series

Rosacea is a chronic inflammatory skin disease characterized by recurrent episodes of facial flushing, erythema, papules, pustules, and telangiectasia. More than half of all rosacea patients may have ocular symptoms. Rosacea is associated with certain digestive diseases, such as gastritis, hypochlorhydria, or a number of jejunal mucosal abnormalities, and many patients have Helicobacter pylori infection. The role of Helicobacter pylori has often been a subject of investigation; these studies show conflicting results. Here we present results of the effects of treatment given for H. pylori eradication in seven patients with ocular rosacea that, at the same time, had clinical and serological evidence of H. pylori infection. Six weeks after completion of the treatment, all patients experienced improvement of their rosacea symptoms. Ocular disease responded better than cutaneous rosacea.

Aktuelles Verständnis der Pathophysiologie der Rosazea

Rosacea is a chronic inflammatory skin disease mainly affecting the face. Four major clinical subtypes of rosacea can be identified: erythemato-telangiectatic, papulopustular, phymatous and ocular rosacea. Still, it is currently unclear whether these subtypes develop consecutively or if any subtypes may occur individually as part of a syndrome. Rosacea is characterized by facial flushing, erythema, chronic inflammation, edema and fibrosis. Several trigger factors can worsen the disease or cause recurring episodes of inflammation. Although some aspects in the pathophysiology of rosacea have been characterized in more detail during the past years, the precise interplay of the various dysregulated systems is still poorly understood. In early disease manifestations and milder stages, dysfunction of neurovascular regulation and the innate immune system seem to be driving forces in rosacea pathophysiology. A disturbed chemokine and cytokine network further contributes to disease progression. This current review highlights some of the recent findings in rosacea pathophysiology and points out novel targets for therapeutic intervention.     

Rosacea in the pediatric population

Rosacea is a condition of vasomotor instability characterized by facial erythema most notable in the central convex areas of the face, including the forehead, cheek, nose, and perioral and periocular skin. Rosacea tends to begin in childhood as common facial flushing, often in response to stress. A diagnosis beyond this initial stage of rosacea is unusual in the pediatric population. If a child is identified with the intermediate stage of rosacea, consisting of papules and pustules, an eye examination should be performed to rule out ocular manifestations. It may be beneficial to recognize children in the early stage of rosacea; however, it is uncertain if prophylactic treatment is necessary.     

Prognosis of 234 rosacea patients according to clinical subtype: The significance of central facial erythema in the prognosis of rosacea

Rosacea has a wide spectrum of clinical features, which include persistent facial redness, flushing, telangiectasia, inflammatory papules/pustules, hypertrophy and/or ocular features. The prognosis of rosacea according to clinical subtype has not been evaluated. We analyzed the prognosis of rosacea in 234 patients, which included 120 patients with mixed subtype, 75 with the erythematotelangiectatic rosacea subtype and 39 with the papulopustular rosacea (PPR) subtype. The prognosis of rosacea was classified as: (i) no improvement; (ii) partial remission; and (iii) complete remission. The frequencies of complete remission, time to complete remission and 1‐year complete remission rate were compared between subtypes. Follow‐up periods ranged 2–72 months (median follow‐up, 17.5). Aggravation of the disease was found in 50.4% of patients during follow up. Partial or complete remission was noted in 61.5% and 20.9% of patients, respectively. The median time to complete remission was 56.0 months. The prognosis of disease was more favorable for patients with the PPR subtype than for patients with other subtypes with respect to the frequency of complete remission, median time to complete remission and the 2‐year complete remission rate. In conclusion, papulopustular rosacea without remarkable centrofacial erythema showed a more favorable prognosis than other subtypes. Erythematotelangiectatic lesions in rosacea patients present a challenge for the treatment of rosacea.     

Experiences of rosacea and its treatment: an interpretative phenomenological analysis

Rosacea is a skin disorder which causes flushing and redness of the face. Relatively few people with rosacea receive specialist dermatology treatment or psychological support. Despite this, individuals with rosacea can experience social anxiety, depression and embarrassment, and decreased quality of life. Whilst questionnaire based studies have been used to investigate the type of distress that people living with rosacea might experience, there are no studies that have sought to gain an in‐depth understanding of the experiences of living with this visible skin condition. Therefore, this study used face‐to‐face interviews to learn about participants' complex, individual experience of life with rosacea. A qualitative approach called interpretative phenomenological analysis (IPA) was used to guide the interviews and analysis. This approach to research focuses on individual accounts and has been extensively used to investigate illness experience. In this study nine participants took part in detailed semi‐structured interviews. Three overarching themes were gleamed from these interviews; self‐consciousness, which focused on the fear of others assigning blame to participants for having caused their own symptoms; avoidance, concealment, and hiding emotions, referring to the coping strategies participants employed in response to rosacea; and inconsistencies in treatment, which focused on the need for medical professionals to assess the emotional wellbeing of patients with rosacea. The findings are consistent with qualitative findings from patients with other skin conditions that demonstrate that self‐conscious emotions can be a significant part of the experience of life with a skin condition. Healthcare professionals need to take care to assess for the presence of such concerns in rosacea, and where unhelpful thoughts or beliefs are reported, patients may benefit from dermatology specific psychological support.
