RESUMO

BACKGROUND AND RATIONALE: Xerosis cutis (also referred to as xeroderma, dry skin, asteatosis) affects more than 10 million individuals in Germany. It is among the most common dermatological diagnoses and a cardinal symptom of many dermatological, internal and neurological diseases. Even though it has been established that basic skin care plays a significant role in the management of patients with xerosis cutis, there are as yet no evidence-based algorithms for diagnosis and treatment. OBJECTIVE: The present position paper provides physicians across all specialties with a practical, symptom-based approach to the prevention, diagnosis and treatment of xerosis cutis. METHODS: Within a structured decision-making process, a panel of experienced dermatologists first defined questions relevant to everyday clinical practice, which were then addressed by a systematic review of the literature. Based on the evidence available as well as expert consensus, diagnostic and treatment algorithms were subsequently developed and agreed upon. RESULTS: Xerosis cutis is generally diagnosed on clinical grounds. Possible trigger factors must be avoided, and comorbidities should be adequately and specifically treated. Suitable skin care products should be chosen with a view to improving skin hydration and restoring its barrier function. They should therefore contain both rehydrating and lipid-replenishing components. The "drier" the skin appears, the greater the lipid content should be (preferably using water-in-oil formulations). The choice of ingredients is based on a patient's individual symptoms, such as scaling (e.g., urea), fissures/rhagades (e.g., urea or dexpanthenol), erythema (e.g., licochalcone A) and pruritus (e.g., polidocanol). Other factors to be considered include the site affected and patient age. Ingredients or rather combinations thereof for which there is good clinical evidence should be preferentially used. The best evidence by far is available for urea, whose efficacy in the treatment of xerosis is further enhanced by combining it with other natural moisturizing components and ceramides. The "xerosimeter" is a tool developed in an effort to facilitate patient management and for training purposes. It not only includes practical tools for diagnosis and follow-up but also a classification of ingredients and a structured treatment algorithm. CONCLUSION: The structured symptom- and evidence-based approach proposed herein contains a road map for diagnosis and treatment of xerosis cutis. It aims to raise awareness in terms of prevention and early treatment of this condition and may thus improve quality of life and prevent potential sequelae.

RESUMO

HINTERGRUND UND RATIONALE: Die Xerosis cutis (Synonym: Xerodermie, trockene Haut, hydrolipidarme Haut) ist mit > 10 Millionen Betroffenen nicht nur eine der häufigsten dermatologischen Diagnosen in Deutschland, sondern auch Leitsymptom vieler dermatologischer, internistischer und neurologischer Erkrankungen. Trotz der medizinischen Relevanz der topischen Basistherapie für die Xerosis cutis gibt es in Deutschland für ihr Management bisher keinen wissenschaftlich belegten Diagnostik- und Therapiealgorithmus. ZIEL: Dieses Positionspapier vermittelt Ärzten fachübergreifend einen an individuellen Symptomen orientierten, praxisnahen Leitfaden für die Prävention, Diagnostik und Therapie der Xerosis cutis. METHODIK: Im Rahmen eines strukturierten Entscheidungsprozesses wurden von erfahrenen dermatologischen Experten zunächst praxisrelevante Fragestellungen definiert und systematisch aufgearbeitet. Auf der Basis von Evidenz und Expertenkonsens wurden daraus diagnostische und therapeutische Algorithmen mit Empfehlungen für die Praxis entwickelt und konsentiert. ERGEBNIS: Die Xerosis cutis kann grundsätzlich klinisch diagnostiziert werden. Auslöser und/oder Grunderkrankungen müssen abgeklärt und vermieden bzw. spezifisch behandelt werden. Bei der Wahl der geeigneten Basistherapie ist es wichtig, dass nicht nur die Hauthydratation verbessert, sondern auch die Barrierefunktion der Haut wiederhergestellt wird. Sie sollte daher aus einer Kombination von rückfeuchtenden und rückfettenden Inhaltsstoffen bestehen. Je trockener die Haut, desto lipidhaltiger sollte die Hautpflege sein (bevorzugt Wasser-in-Öl-Formulierungen). Die individuelle Auswahl der Inhaltsstoffe orientiert sich nach kausaler Prüfung an den Symptomen Schuppung (v.a. Urea), Fissuren/Rhagaden (v.a. Urea oder Dexpanthenol), Rötung (v.a. Licochalcone A) und Pruritus (v.a. Polidocanol), sowie an der Lokalisation und dem Alter der Patienten. Inhaltsstoffe bzw. Inhaltsstoffkombinationen mit guter Studienevidenz sind zu bevorzugen. Die mit Abstand beste Evidenz bei der Xerosis cutis weist Urea auf, dessen Wirksamkeit in Kombination mit anderen natürlichen Feuchthalte-Komponenten und Ceramiden noch gesteigert werden kann. Zur Arbeitserleichterung am Patienten und zum besseren Erlernen wurde das Xerosimeter entwickelt, das die praktische Umsetzung der Diagnostik und Verlaufskontrolle, eine Klassifikation der Inhaltsstoffe und einen strukturierten Therapiealgorithmus enthält. SCHLUSSFOLGERUNG: Das hier vorgeschlagene strukturierte symptom- und evidenzorientierte Vorgehen mit Diagnostik- und Behandlungspfad soll für die Prävention und frühzeitige Behandlung der Xerosis cutis sensibilisieren. Damit können die Lebensqualität verbessert und Folgeerkrankungen verhindert werden.

RESUMO

BACKGROUND: Photodynamic therapy (PDT) is increasingly used for the treatment of actinic keratosis (AK). OBJECTIVES: To investigate both the efficacy of different application times and the safety of a novel patch (PD P 506 A) containing aminolaevulinic acid in the PDT of mild to moderate AK. METHODS: Applications of PD P 506 A for 0.5, 1, 2 and 4 h were compared in a multicentre, randomized, blinded-observer, parallel-group study. After patch removal, study lesions were illuminated with red light (lambda(em) approximately 630 nm; 37 J/cm(2)). Study lesions were not pretreated (e.g. by curettage) prior to PDT. Efficacy was evaluated 4 and 8 weeks after treatment. Safety and tolerability were determined through laboratory analyses and documentation of both local reactions and adverse events. RESULTS: A total of 149 patients were initially enrolled. Of these, 140 patients (520 lesions) completed the study according to protocol. Eight weeks after treatment, 86% of the AK lesions (74% of the patients) treated with 4-h patch application showed complete clearance. The complete clearance rates of lesions (patients) for the 2-, 1- and 0.5-h treatment arms were 73% (47%), 72% (50%) and 51% (24%), respectively. Statistically, the 4-h application was identified as the 'best treatment'. Patients with clearance seemed to experience local reactions to a greater extent than patients without clearance. Local reactions to study treatments did not exceed the expected range. CONCLUSIONS: The results of this first clinical efficacy study suggest excellent therapeutic outcomes with a single PD P 506 A PDT with a 4-h application.
