Explore the Research 연구 살펴보기Topical Steroid Withdrawal (TSW), also known as Steroid Skin Syndrome (SSS) or Red Skin Syndrome (RSS), is a severe iatrogenic condition that develops following the discontinuation of prolonged topical corticosteroid use. Unlike atopic dermatitis or allergic reactions, TSW is a drug withdrawal syndrome characterized by a rebound inflammatory response that can be more severe than the original skin condition it was prescribed to treat.
TSW is not a disease—it is a predictable physiological response to abrupt cessation of topical corticosteroids. The skin becomes dependent on these medications, and when they are withdrawn, the body experiences a hyperinflammatory rebound. This condition is preventable through gradual tapering and physician awareness, yet it remains severely underrecognized in medical practice.
The hallmark symptoms of TSW include intense erythema (redness), burning sensation, severe pruritus (itching), edema (swelling), exudation (weeping), and skin barrier dysfunction. Symptoms typically appear within 2–7 days of discontinuing topical corticosteroids and can persist for weeks to years depending on the duration and potency of prior steroid use. In severe cases, patients may experience systemic symptoms including fever, chills, and lymphadenopathy.
경피 스테로이드 금단(TSW), 또는 스테로이드 피부 증후군(SSS), 홍피증후군(RSS)으로도 알려진 이 증상은 장기간 경피 스테로이드 사용 후 중단으로 인해 발생하는 심각한 의원병입니다. 아토피 피부염이나 알레르기 반응과 달리, TSW는 원래 치료하려던 피부 상태보다 더 심할 수 있는 리바운드 염증 반응을 특징으로 하는 약물 금단 증후군입니다.
TSW는 질병이 아닙니다—이것은 경피 스테로이드 중단에 따른 예측 가능한 생리적 반응입니다. 피부가 이 약물에 의존하게 되고, 중단하면 신체는 과도한 염증 리바운드를 경험합니다. 이 상태는 점진적인 감량과 의사의 인식을 통해 예방 가능하지만, 의료 현장에서 여전히 심각하게 인식되지 않고 있습니다.
TSW의 특징적인 증상은 심한 홍반(발적), 작열감, 심한 소양증(가려움), 부종(부기), 삼출(진물), 피부 장벽 기능 장애입니다. 증상은 일반적으로 경피 스테로이드 중단 후 2~7일 내에 나타나며, 이전 스테로이드 사용의 기간과 효력에 따라 수주에서 수년까지 지속될 수 있습니다. 심한 경우, 환자는 발열, 오한, 림프절병증을 포함한 전신 증상을 경험할 수 있습니다.
局所ステロイド離脱(TSW)、別名ステロイド皮膚症候群(SSS)または赤皮症候群(RSS)は、長期的な局所コルチコステロイド使用の中止に続いて発生する重篤な医原病です。アトピー性皮膚炎やアレルギー反応とは異なり、TSWは、元々治療するために処方された皮膚状態よりも重篤である可能性のあるリバウンド炎症反応を特徴とする薬物離脱症候群です。
TSWは病気ではありません—これは局所コルチコステロイド中止に対する予測可能な生理的反応です。皮膚はこれらの薬剤に依存するようになり、それらが中止されると、体は過度な炎症リバウンドを経験します。この状態は段階的な減量と医師の認識を通じて予防可能ですが、医療現場ではまだ深刻に認識されていません。
TSWの特徴的な症状は、激しい紅斑(発赤)、灼熱感、激しい掻痒感(かゆみ)、浮腫(腫れ)、滲出液(浸出液)、皮膚バリア機能障害です。症状は通常、局所コルチコステロイド中止後2~7日以内に現れ、以前のステロイド使用の期間と効力に応じて、数週間から数年間持続する可能性があります。重篤な場合、患者は発熱、悪寒、リンパ節症を含む全身症状を経験する可能性があります。
局部类固醇戒断(TSW),也称为类固醇皮肤综合征(SSS)或红皮综合征(RSS),是长期使用局部皮质类固醇后停用而引发的严重医源性疾病。与特应性皮炎或过敏反应不同,TSW是一种药物戒断综合征,其特征是反弹性炎症反应,可能比最初处方治疗的皮肤状况更严重。
TSW不是一种疾病——它是停止使用局部皮质类固醇的可预测的生理反应。皮肤对这些药物产生依赖,当停用时,身体会经历过度炎症反弹。这种情况可以通过逐步减量和医生意识来预防,但在医疗实践中仍然严重被认识不足。
TSW的典型症状包括剧烈红斑(发红)、灼热感、严重瘙痒、水肿(肿胀)、渗出液(渗液)和皮肤屏障功能障碍。症状通常在停用局部皮质类固醇后2-7天内出现,并可能根据先前类固醇使用的持续时间和效力持续数周至数年。在严重情况下,患者可能会经历包括发热、寒战和淋巴结病在内的全身症状。
Abstinencia de Esteroides Tópicos (TSW), también conocida como Síndrome de Piel de Esteroides (SSS) o Síndrome de Piel Roja (RSS), es una condición iatrogénica grave que se desarrolla tras la interrupción del uso prolongado de corticosteroides tópicos. A diferencia de la dermatitis atópica o las reacciones alérgicas, TSW es un síndrome de abstinencia de drogas caracterizado por una respuesta inflamatoria de rebote que puede ser más grave que la condición de piel original para la que se prescribió.
TSW no es una enfermedad—es una respuesta fisiológica predecible a la interrupción abrupta de los corticosteroides tópicos. La piel se vuelve dependiente de estos medicamentos, y cuando se interrumpen, el cuerpo experimenta un rebote hiperinflamatorio. Esta condición es prevenible mediante la reducción gradual y la conciencia del médico, pero sigue siendo severamente desconocida en la práctica médica.
Los síntomas distintivos de TSW incluyen eritema intenso (enrojecimiento), sensación de ardor, prurito severo (picazón), edema (hinchazón), exudación (supuración) y disfunción de la barrera cutánea. Los síntomas típicamente aparecen dentro de 2-7 días de discontinuar los corticosteroides tópicos y pueden persistir durante semanas a años dependiendo de la duración y potencia del uso previo de esteroides. En casos graves, los pacientes pueden experimentar síntomas sistémicos incluyendo fiebre, escalofríos y linfadenopatía.
การหยุดสเตียรอยด์ทางผิว (TSW) หรือที่เรียกว่า 증후군ผิวสเตียรอยด์ (SSS) หรือ 증후군ผิวแดง (RSS) เป็นโรคที่เกิดจากการแพทย์ที่ร้ายแรงซึ่งเกิดขึ้นจากการหยุดใช้สเตียรอยด์ทางผิวระยะยาว ต่างจากเดอร์มาทิติสแอตปิกหรือปฏิกิริยาแพ้ TSW คือ 증후군การหยุดยาสูบ ที่มีลักษณะเป็นปฏิกิริยาอักเสบการสะดุดที่อาจรุนแรงกว่าสภาวะผิวเดิมที่ได้รับการสั่งให้รักษา
TSW ไม่ใช่โรค—มันเป็นปฏิกิริยาทางสรีรวิทยาที่คาดเดาได้จากการหยุดสเตียรอยด์ทางผิวอย่างกะทันหัน ผิวหนังกลายเป็นผู้ติดยาจากยาเหล่านี้ และเมื่อหยุดใช้ ร่างกายจะประสบปฏิกิริยาอักเสบที่มากเกินไป สภาวะนี้ ป้องกันได้ ผ่านการลดลงทีละน้อยและการตระหนักรู้ของแพทย์ แต่ยังคงไม่เป็นที่รู้จักอย่างมากในการปฏิบัติทางการแพทย์
อาการเด่นของ TSW ได้แก่ เรดเนส (การแดง) การไหม้ การคัน ตัวอักษร (บวม) การไหลออก และการทำงานของกำแพงผิวหนังที่ผิดปกติ อาการมักปรากฏภายใน 2-7 วันหลังจากหยุดใช้สเตียรอยด์ทางผิวและสามารถคงอยู่ได้นานหลายสัปดาห์ถึงหลายปีขึ้นอยู่กับระยะเวลาและประสิทธิภาพของการใช้สเตียรอยด์ก่อนหน้า ในกรณีที่รุนแรง ผู้ป่วยอาจประสบอาการทั่วร่างกายรวมถึงไข้ หนาวสั่น และโรคต่อมน้ำเหลือง
The human body is home to trillions of microorganisms, collectively known as the microbiome. These microscopic communities, residing on the skin and in the gut, play a crucial role in our health, particularly in modulating the immune system. Recent scientific research has shed light on the intricate relationship between the microbiome and atopic dermatitis (AD), a chronic inflammatory skin condition.
A consistent finding across multiple studies is that individuals with atopic dermatitis exhibit an imbalance, or "dysbiosis," in both their skin and gut microbiomes. This dysbiosis is characterized by a decrease in microbial diversity and an overgrowth of certain pathogenic bacteria, most notably Staphylococcus aureus. As highlighted by Paller et al. (2019), the reduction in microbial diversity on the skin of AD patients is directly correlated with the severity of the disease. This is further supported by Kim et al. (2019), who noted that AD patients have a disturbed microbial composition and lack microbial diversity in both their skin and gut compared to healthy individuals.
The "gut-skin axis" is a concept that has gained significant attention in understanding atopic dermatitis. This bidirectional communication pathway between the gut and the skin means that an unhealthy gut microbiome can influence skin health. Fang et al. (2021) explain that gut dysbiosis can lead to a compromised intestinal barrier, allowing inflammatory substances to enter the bloodstream and trigger or worsen skin inflammation. This systemic effect underscores the importance of a healthy gut in managing atopic dermatitis.
Topical Steroid Withdrawal (TSW) is a condition that can occur after discontinuing long-term use of topical steroids. Research by Maskey et al. (2025) indicates that a significant number of individuals going through TSW experience secondary bacterial infections, often characterized by a heavy colonization of S. aureus and notable alterations in the skin microbiome. This suggests that the skin microbiome is a critical factor in the TSW process.
The promising news is that these findings are opening doors to new therapeutic strategies. Hou et al. (2025) discuss the potential of using microbial signatures as predictive biomarkers for AD and the promise of novel treatments like probiotics and microbiota transplantation to restore a healthy microbial balance. Probiotics can help restore intestinal function and reshape the gut microbiome, potentially alleviating AD symptoms. Similarly, the topical application of beneficial commensal bacteria has shown promise in reducing AD severity by combating the overgrowth of S. aureus.
인체에는 수조 개의 미생물이 서식하고 있으며, 이를 통칭하여 마이크로바이옴이라 합니다. 피부와 장에 존재하는 이 미생물 군집은 특히 면역 체계를 조절하는 데 중요한 역할을 합니다. 최근 과학 연구는 마이크로바이옴과 만성 염증성 피부 질환인 아토피 피부염(AD) 사이의 복잡한 관계를 밝혀내고 있습니다.
여러 연구에서 일관되게 발견된 사실은, 아토피 피부염 환자들이 피부와 장 마이크로바이옴 모두에서 "디스바이오시스(불균형)"를 보인다는 것입니다. 이 불균형은 미생물 다양성의 감소와 특정 병원성 세균, 특히 황색포도상구균(Staphylococcus aureus)의 과증식이 특징입니다. Paller 등(2019)의 연구에 따르면, AD 환자의 피부 미생물 다양성 감소는 질병의 중증도와 직접적으로 상관관계가 있습니다. Kim 등(2019)도 AD 환자가 건강한 사람에 비해 피부와 장 모두에서 미생물 구성이 교란되고 다양성이 부족하다고 보고했습니다.
"장-피부 축(Gut-Skin Axis)"은 아토피 피부염을 이해하는 데 큰 주목을 받고 있는 개념입니다. 장과 피부 사이의 이 양방향 소통 경로는 불건강한 장 마이크로바이옴이 피부 건강에 영향을 미칠 수 있음을 의미합니다. Fang 등(2021)은 장 디스바이오시스가 장 장벽을 손상시켜 염증 물질이 혈류로 유입되고, 이것이 피부 염증을 유발하거나 악화시킬 수 있다고 설명합니다.
스테로이드 리바운드(TSW)는 장기간 사용한 스테로이드 외용제를 중단한 후 발생할 수 있는 상태입니다. Maskey 등(2025)의 연구에 따르면, TSW를 겪는 상당수의 환자들이 황색포도상구균의 과다 집락화와 피부 마이크로바이옴의 현저한 변화를 특징으로 하는 이차 세균 감염을 경험합니다.
희망적인 소식은 이러한 발견들이 새로운 치료 전략의 문을 열고 있다는 것입니다. Hou 등(2025)은 미생물 특성을 AD의 예측 바이오마커로 활용할 가능성과 프로바이오틱스 및 미생물 이식 등 건강한 미생물 균형을 회복하기 위한 새로운 치료법의 가능성을 논의합니다. 프로바이오틱스는 장 기능을 회복하고 장 마이크로바이옴을 재형성하여 AD 증상을 완화할 수 있습니다.
While supplementation provides targeted micronutrients, the dietary foundation plays an equally critical role in atopic dermatitis recovery. This section analyzes the whole-food, plant-based dietary protocol used during the 17-month healing journey. Rather than restrictive dieting, this approach emphasizes nutrient-dense, anti-inflammatory foods that support gut health, reduce systemic inflammation, and strengthen the skin barrier.
The dietary strategy centered on intermittent eating windows (typically 9 AM to 3 PM) combined with whole plant foods rich in fiber, phytonutrients, and antioxidants. This approach allowed the digestive system adequate rest while ensuring consistent nutrient intake during active hours. The protocol evolved from an elimination phase (avoiding common triggers like processed foods, dairy, and gluten) to a reintroduction phase (gradually testing tolerance to various foods).
The core dietary pillars were: steamed cruciferous vegetables (broccoli, cabbage, bell peppers) for sulforaphane and glucosinolates, sweet potatoes with skin for resistant starch and fiber, bananas for potassium and resistant starch, fresh detox juices for concentrated micronutrients, and consistent water intake (2.5L daily) for hydration and toxin elimination. These foods were selected based on their anti-inflammatory properties, gut microbiome support, and skin barrier strengthening effects.
보충제가 표적 미량 영양소를 제공하는 동안, 식이 기초는 아토피 피부염 회복에 동등하게 중요한 역할을 합니다. 이 섹션은 17개월 치유 여정에서 사용된 전체 식품, 식물 기반 식이 프로토콜을 분석합니다. 제한적인 식단이 아닌, 이 접근법은 장 건강을 지원하고 전신 염증을 줄이며 피부 장벽을 강화하는 영양이 풍부한 항염증 식품을 강조합니다.
식이 전략은 간헐적 식사 시간(일반적으로 오전 9시~오후 3시)과 섬유질, 식물 영양소, 항산화제가 풍부한 전체 식물 식품을 결합한 것입니다. 이 접근법은 소화 시스템에 충분한 휴식을 제공하면서 활동 시간 동안 일관된 영양 섭취를 보장했습니다. 프로토콜은 제거 단계(가공식품, 유제품, 글루텐 같은 일반적인 유발 요인 회피)에서 재도입 단계(다양한 식품에 대한 내성을 점진적으로 테스트)로 진화했습니다.
핵심 식이 축은 설포라판과 글루코시놀레이트를 위한 찐 십자화과 야채(브로콜리, 양배추, 피망), 저항성 전분과 섬유질을 위한 껍질이 있는 고구마, 칼륨과 저항성 전분을 위한 바나나, 농축된 미량 영양소를 위한 신선한 해독주스, 수분 공급과 독소 제거를 위한 일관된 물 섭취(하루 2.5L)였습니다. 이러한 식품들은 항염증 특성, 장내 마이크로바이옴 지원, 피부 장벽 강화 효과를 기반으로 선택되었습니다.
サプリメントが標的微量栄養素を提供する一方、食事基盤はアトピー性皮膚炎の回復において同等に重要な役割を果たします。このセクションでは、17ヶ月の治癒の旅で使用された全食品、植物ベースの食事プロトコルを分析します。制限的な食事ではなく、このアプローチは腸の健康をサポートし、全身炎症を減らし、皮膚バリアを強化する栄養豊富な抗炎症食品を強調しています。
食事戦略は間欠的な食事時間(通常午前9時~午後3時)と、食物繊維、植物栄養素、抗酸化物質が豊富な全植物食品の組み合わせに焦点を当てていました。このアプローチにより、消化器系に十分な休息を与えながら、活動時間中に一貫した栄養摂取を確保しました。プロトコルは除去段階(加工食品、乳製品、グルテンなどの一般的なトリガーを回避)から再導入段階(様々な食品への耐性を段階的にテスト)へと進化しました。
主要な食事の柱は、スルフォラファンとグルコシノレートのための蒸したアブラナ科野菜(ブロッコリー、キャベツ、ピーマン)、耐性デンプンと食物繊維のための皮付きサツマイモ、カリウムと耐性デンプンのためのバナナ、濃縮微量栄養素のための新鮮なデトックスジュース、水分補給と毒素除去のための一貫した水分摂取(1日2.5L)でした。これらの食品は抗炎症特性、腸内マイクロバイオムサポート、皮膚バリア強化効果に基づいて選択されました。
虽然补充剂提供了有针对性的微量营养素,但饮食基础在特应性皮炎恢复中起着同样重要的作用。本节分析了17个月治愈之旅中使用的全食品、植物性饮食方案。这种方法不是限制性饮食,而是强调营养丰富、抗炎食品,支持肠道健康、减少全身炎症并加强皮肤屏障。
饮食策略以间歇性进食时间(通常上午9点至下午3点)和富含纤维、植物营养素和抗氧化剂的全植物食品为中心。这种方法允许消化系统充分休息,同时在活动时间内确保营养摄入一致。该方案从消除阶段(避免加工食品、乳制品和麸质等常见触发因素)演变为重新引入阶段(逐步测试对各种食品的耐受性)。
核心饮食支柱包括:用于硫代葡萄糖苷的蒸十字花科蔬菜(西兰花、卷心菜、甜椒)、用于抗性淀粉和纤维的带皮红薯、用于钾和抗性淀粉的香蕉、用于浓缩微量营养素的新鲜排毒果汁以及用于水合和毒素清除的一致的水摄入(每天2.5升)。这些食品是根据其抗炎特性、肠道微生物群支持和皮肤屏障强化效果选择的。
Mientras que los suplementos proporcionan micronutrientes específicos, la base dietética juega un papel igualmente crítico en la recuperación de la dermatitis atópica. Esta sección analiza el protocolo dietético integral basado en plantas utilizado durante el viaje de curación de 17 meses. En lugar de una dieta restrictiva, este enfoque enfatiza alimentos ricos en nutrientes y antiinflamatorios que apoyan la salud intestinal, reducen la inflamación sistémica y fortalecen la barrera cutánea.
La estrategia dietética se centró en ventanas de alimentación intermitente (típicamente de 9 AM a 3 PM) combinadas con alimentos vegetales integrales ricos en fibra, fitonutrientes y antioxidantes. Este enfoque permitió al sistema digestivo un descanso adecuado mientras aseguraba una ingesta nutricional consistente durante las horas activas. El protocolo evolucionó de una fase de eliminación (evitando desencadenantes comunes como alimentos procesados, productos lácteos y gluten) a una fase de reintroducción (probando gradualmente la tolerancia a varios alimentos).
Los pilares dietéticos principales fueron: verduras crucíferas al vapor (brócoli, repollo, pimientos) para sulforafano y glucosinolatos, batatas con piel para almidón resistente y fibra, plátanos para potasio y almidón resistente, jugos de desintoxicación frescos para micronutrientes concentrados e ingesta consistente de agua (2,5L diarios) para hidratación y eliminación de toxinas. Estos alimentos fueron seleccionados en función de sus propiedades antiinflamatorias, apoyo al microbioma intestinal y efectos de fortalecimiento de la barrera cutánea.

Atopic dermatitis (AD) is a chronic inflammatory skin condition characterized by dry, itchy, and inflamed skin. The health of the skin barrier is crucial in AD, and it is highly sensitive to environmental factors. For many years, patients and clinicians have suspected a link between water and eczema, specifically concerning the hardness of domestic water and the role of hydration.
Multiple studies have identified an association between living in a hard water area and the prevalence of atopic dermatitis. Hard water is defined by its high concentration of minerals, primarily calcium and magnesium. An influential study by McNally et al. (1998) was among the first to systematically investigate this link, finding a significantly higher prevalence of eczema in children living in areas with harder water. More recently, Lopez et al. (2022) using data from the UK Biobank confirmed this association in adults, finding that higher domestic hard water concentrations were associated with an increased prevalence of eczema in middle-aged adults.
How does hard water affect the skin? Research points to its impact on the skin barrier. The skin surface is naturally acidic, which is essential for its barrier function. Hard water is alkaline and can disrupt this natural acidity. A key study by Danby et al. (2018) demonstrated that washing with hard water increases the deposition of harsh surfactants, such as sodium lauryl sulphate (SLS), on the skin. The calcium in hard water binds to the surfactant, creating a residue that is difficult to rinse off and is particularly irritating to the skin.
While external factors are important, the role of internal hydration cannot be overlooked. A review by Douladiris et al. (2023) concluded that while topical moisturizers remain the first-line treatment for dry skin in AD, adequate dietary water intake does contribute to better skin hydration, especially in individuals who typically have low water consumption.
The Softened Water Eczema Trial (SWET) by Thomas et al. (2011), a large randomized controlled trial, enrolled 336 children with moderate to severe eczema. Surprisingly, the results showed no statistically significant difference in eczema severity between the water softener group and the control group. This suggests that while hard water is associated with a higher risk of eczema, installing a water softener is not an effective treatment for children who already have the condition. A systematic review by Jabbar-Lopez et al. (2021) further confirmed these findings.
아토피 피부염(AD)은 건조하고 가려우며 염증이 있는 피부를 특징으로 하는 만성 염증성 피부 질환입니다. 피부 장벽의 건강은 AD에서 매우 중요하며, 환경 요인에 매우 민감합니다. 오랫동안 환자와 임상의들은 물과 습진 사이의 연관성, 특히 생활용수의 경도(硬度)와 수분 공급의 역할에 대해 의심해 왔습니다.
여러 연구에서 경수(센물) 지역에 거주하는 것과 아토피 피부염 유병률 사이의 연관성을 확인했습니다. 경수는 주로 칼슘과 마그네슘의 높은 농도로 정의됩니다. McNally 등(1998)의 영향력 있는 연구는 이 연관성을 체계적으로 조사한 최초의 연구 중 하나로, 경수 지역 어린이들에서 습진 유병률이 유의하게 높다는 것을 발견했습니다. 최근 Lopez 등(2022)은 UK Biobank 데이터를 사용하여 성인에서도 이 연관성을 확인했습니다.
경수는 어떻게 피부에 영향을 미칠까요? 연구는 피부 장벽에 대한 영향을 지적합니다. 피부 표면은 자연적으로 산성이며, 이는 장벽 기능에 필수적입니다. 경수는 알칼리성이어서 이 자연적인 산성도를 교란할 수 있습니다. Danby 등(2018)의 핵심 연구는 경수로 세안하면 소듐 라우릴 설페이트(SLS) 같은 강한 계면활성제가 피부에 더 많이 침착된다는 것을 입증했습니다.
외부 요인도 중요하지만, 내부 수분 공급의 역할도 간과할 수 없습니다. Douladiris 등(2023)의 리뷰는 국소 보습제가 AD의 건조한 피부에 대한 1차 치료법이지만, 적절한 식이 수분 섭취가 피부 수분에 기여한다고 결론지었습니다.
연수기 습진 임상시험(SWET)은 Thomas 등(2011)이 수행한 대규모 무작위 대조 시험으로, 중등도~중증 습진을 가진 336명의 어린이를 등록했습니다. 놀랍게도, 연수기 그룹과 대조군 사이에 습진 중증도에서 통계적으로 유의한 차이가 없었습니다. 이는 경수가 습진 위험 증가와 관련이 있지만, 이미 질환이 있는 어린이에게 연수기 설치가 효과적인 치료법은 아님을 시사합니다.
