Abstract: The objective of this systematic review, which was performed following the guidelines of the Cochrane collaboration, was to assess the effects of interventions for treatment of atopic dermatitis (AD) in dogs. Citations identified from three databases (MEDLINE, Thomson’s Science Citation Index Expanded and CAB Abstracts) and trials published by December 2007 were selected. Proceedings books from the major veterinary dermatology international congresses were hand searched for relevant citations. The authors selected randomized controlled trials (RCTs), published from January 1980 to December 2007, which reported the efficacy of topical or systemic interventions for treatment or prevention of canine AD. Studies had to report assessments of either pruritus or skin lesions, or both. Studies were selected and data extracted by two reviewers, with discrepancies resolved by a third arbitrator. Missing data were requested from study authors of recently published trials. Pooling of results and meta-analyses were performed for studies reporting similar interventions and outcome measures. A total of 49 RCTs were selected, which had enrolled 2126 dogs. This review found some evidence of efficacy of topical tacrolimus (3 RCTs), topical triamcinolone (1), oral glucocorticoids (5), oral ciclosporin (6), subcutaneous recombinant γ-interferon (1) and subcutaneous allergen-specific immunotherapy (3) to decrease pruritus and/or skin lesions of AD in dogs. One high-quality RCT showed that an oral essential fatty acid supplement could reduce prednisolone consumption by approximately half. Additional RCTs of high design quality must be performed to remedy previous flaws and to test interventions for prevention of flares of this disease.
Resume
L’objectif de cette revue, effectuee selon les recommandations de la « Cochrane collaboration », etait d’evaluer les effets des communications sur le traitement de la dermatite atopique canine (DAC). Les citations retenues a partir de trois bases de donnees (MEDLINE, Thomson’s Science Citation Index Expanded et CAB Abstracts) et les essais publies jusqu’a decembre 2007 ont ete retenus. Les citations pertinentes des proceedings des principaux congres internationaux de dermatologie veterinaire ont ete recherchees manuellement. Les auteurs ont selectionnes les etudes controlees randomisees (RCT) publiees de janvier 1980 a decembre 2007, rapportant l’efficacite des traitements ou preventions topiques ou systemiques de la DAC. Les etudes devaient faire etat du prurit et/ou des lesions cutanees. Les etudes etaient choisies et les donnees recueillies par deux investigateurs, les points de divergence etant arbitre par un troisieme. Les donnees manquantes etaient demandees aux auteurs des etudes les plus recentes. Les resultats ont ete regroupes et des meta-analyses effectuees sur les publications semblables et leurs effets. Quarante-neufs etudes ont au total ete selectionnees, ce qui represente 2 126 chiens. Cette revue a mise en evidence l’efficacite du tacrolimus topique (3 RCT), de la triamcinolone topique (1), des glucocorticoides oraux (5), de la ciclosporine orale (6), de l’interferon-gamma recombinant sous-cutane (1) et de l’immunotherapie specifique d’allergene sous-cutanee (3) dans la diminution du prurit et/ou des lesions cutanees des chiens atopiques. Une etude de haute qualite a montre qu’une supplementation orale en acides gras essentiels pouvait reduire la consommation de prednisolone de moitie.D’autres etudes controlees randomisees de haute qualite doivent etre realisees afin de corriger les erreurs anterieures et de tester les moyens de preventions des poussees de cette maladie.
Resumen
El objetivo de esta revision sistematica, que se realizo siguiendo los parametros de la colaboracion de Cochrane, fue valorar los efectos de diferentes intervenciones en el tratamiento de la dermatitis atopica (AD) en perros. Se buscaron citas en tres diferentes bases de datos (MEDLINE, indice expandido de citas cientificas de Thomson, y los resumenes CAB), asi como pruebas clinicas publicadas hasta diciembre del 2007. Se buscaron manualmente citad en los resumenes de los mas importantes congresos de dermatologia a nivel internacional. Los autores seleccionaron pruebas clinicas al azar controladas y publicadas desde enero de 1980 a diciembre de 2007, las cuales indicaban la eficacia de las intervenciones topicas o sistemicas en el tratamiento o la prevencion de la dermatitis atopica canina. Los estudios tenian que indicar la valoracion del prurito, de las lesiones de la piel o de ambos. Los estudios fueron seleccionados ry los datos extraidos por dos autores. Y las discrepancias se resolvieron por una tercera persona. Los datos que faltaban fueron pedidos a los autores de los estudios en pruebas de reciente publicacion. Se desarrollo una compilacion de resultados y un meta analisis para los estudios que indicaban intervenciones similares y que mencionaban la valoracion de los resultados. Se seccionaron un total de 49 estudios clinicos los cuales agrupaban un total de 2126 perros. Esta revision encontro evidencia de la eficacia del tratamiento topico con tacrolimus (3 estudios), triamcinolona topica (1 estudio), glucocorticoides por via oral (5 estudios), ciclosporina oral (6 estudios) interferon gamma recombinante por via subcutanea (1 estudio) e inmunoterapia especifica de alergeno por via subcutanea (3 estudios) para disminuir el prurito y/o las lesiones de la piel en perros con dermatitis atopica. Un estudio de alta calidad demostro que acidos grasos esenciales suplementados por via oral pueden reducir el consumo de prednisolona aproximadamente a la mitad. Otros estudios adicionales de alta calidad en el diseno se deben realizar para evitar previos defectos y para evaluar las intervenciones para la prevencion de recidivas de la enfermedad.
Zusammenfassung
Das Ziel dieser systematischen Review, die nach den Richtlinien der Cochrane Collaboration durchgefuhrt wurde, war es, die Auswirkungen von Interventionen auf die Behandlung von atopischer Dermatitis (AD) bei Hunden zu erheben. Literaturzitate, die durch drei Datenbasen (MEDLINE, Thomson´s Science Citation Index Expanded und CAB Abstracts) gefunden wurden und Studien, die bis Dezember 2007 publiziert worden waren, wurden ausgewahlt. Proceedings Bucher von wichtigen internationalen veterinardermatologischen Kongressen wurden per Hand auf relevante Zitate durchgesehen. Die Autoren wahlten randomisierte kontrollierte Studien (RCTs) aus, die zwischen Janner 1980 und Dezember 2007 publiziert worden waren und die Wirksamkeit von topischer oder systemischer Interventionen auf die Behandlung oder auf die Pravention von caniner AD beschrieben. Die Studien mussten entweder eine Beurteilung von Juckreiz oder von Hautveranderungen, oder beidem, beschreiben. Die Studien wurden von zwei Reviewern ausgewahlt und von ihnen wurden die Daten exzerpiert, wobei eventuelle Diskrepanzen durch einen dritten Gutachter bereinigt wurden. Fehlende Daten wurden von Autoren von unlangst publizierten Studien nachgefordert. Eine Zusammenfassung der Ergebnisse und eine Meta-Analyse wurden bei Studien, die ahnliche Interventionen und Ergebnisse berichteten, durchgefuhrt. Insgesamt wurden 49 RCTs ausgewahlt, die zusammen 2126 Hunde beinhalteten. In dieser Review wurden Hinweise auf die Wirksamkeit von Takrolimus (3 RCTs), topisch verwendetem Triamcinolon (1), oralen Glukokortikoiden (5), oralem Cyclosporin (6), subkutanem rekombinanten gamma-Interferon (1) und subkutaner Allergen-spezifischer Immuntherapie (3) bei der Verminderung von Pruritus und/oder den Hautlasionen bei caniner AD gefunden. Eine RCT von hoher Qualitat zeigte, dass die Verwendung eines oralen Supplements von essentiellen Fettsauren den Prednisolon-Konsum um etwa die Halfte vermindern konnte. Weitere RCTs mit hoher Studienqualitat mussen durchgefuhrt werden, um fruhere Fehler auszubessern und um Interventionen zu testen, die ein Aufflammen dieser Krankheit verhindern konnen.

TL;DR: Clinical reports vary, in regard to the description of lesions seen in dogs with AD, which reflects a possible confusion with lesions of secondary complications, and highlights the fact that the existence and nature of primary lesions of canine AD are not truly known.
