Clinical effects of 2 commercially available diets on canine atopic dermatitis

Abstract

Objective Canine atopic dermatitis (CAD) is a common skin disease in dogs. Prior studies were able to determine beneficial effects of essential fatty acids (EFA) on the clinical signs of CAD. The aim of this study was set to evaluate the effects of a newly designed, EFA-enriched diet on the clinical signs of CAD compared to another EFA-enriched diet.

Materials and methods In this prospective, randomized, double-blinded study, 31 privately owned dogs with atopic dermatitis received either the control diet (diet A, Hill’s Prescription Diet™ d/d™ Salmon & Rice, n = 17) or the test diet (diet B, Veterinary HPM™ Dermatology Support D1, Virbac, n = 14) for 12 weeks. At the beginning of the study as well as after 4, 8 and 12 weeks, skin lesions and pruritus were evaluated via validated scores and the administered medication was documented. At the same time, the dogs’ coat quality was evaluated via a distinct scoring system. In both groups, a total of 7 dogs each completed the entire study.

Results After 12 weeks, there was a mild improvement in lesion scores, pruritus and coat quality with both diets.

Clinical relevance In this study, both diets improved the patients’ skin lesions pruritus and coat quality.

Zusammenfassung

Ziel Die kanine atopische Dermatitis ist eine häufige Hauterkrankung von Hunden. Frühere Studien zeigten positive Auswirkungen essenzieller Fettsäuren (EFA) auf die klinischen Symptome dieser Erkrankung. Ziel dieser Studie war es, die Wirkung einer neu konzipierten, mit EFA angereicherten Diät auf die klinischen Anzeichen der atopischen Dermatitis bei Hunden im Vergleich zu einer anderen mit EFA angereicherten Diät zu bewerten.

Material und Methoden In dieser prospektiven, randomisierten Doppelblindstudie erhielten 31 privat gehaltene Hunde mit atopischer Dermatitis entweder die Kontrolldiät (Diät A, Hill‘s Prescription Diet™ d/d™ Hundefutter mit Lachs und Reis, n = 17) oder die Testdiät (Diät B, Veterinary HPM™ Dermatology Support D1, Virbac, n = 14) über 12 Wochen. Zu Studienbeginn sowie nach 4, 8 und 12 Wochen wurden Hautläsionen und Juckreiz mit validierten Scores bewertet und die verabreichten Medikamente dokumentiert. Gleichzeitig erfolgte eine Beurteilung der Fellqualität der Hunde mit einem eigenen Scoring-System. In beiden Gruppen vollendeten jeweils 7 Patienten die komplette Studienphase.

Ergebnisse Nach 12 Wochen hatten sich die Läsionswerte und der Juckreiz sowie die Fellqualität mit beiden Futtern leicht verbessert.

Klinische Relevanz Beide Futter konnten in dieser Studie den Juckreiz, die Läsionen und die Fellqualität leicht verbessern.
