Abstract

Itraconazole was found to be an effective antifungal for the treatment of canine Malassezia dermatitis (MD). MD was diagnosed in 18 dogs, which were treated with itraconazole administered orally at 5 mg/kg of body weight, q12hrs, for 21 to 30 days. High prevalence breeds of MD were Maltese $(22\%)$, Cocker Spaniel $(17\%)$, Pekingese $(11\%)$, and Vizsla $(11\%)$. The dermatological signs of Malassezia dermatitis were crust $(31\%)$, alopecia $(25\%)$, hyperpigmentation $(25\%)$, scales$(19\%)$, erythema $(13\%)$, lichenification $(11\%)$, pustule $(11\%)$, ear swelling$(11\%)$, papules $(5\%)$, and offensive odor $(5\%)$. Commonly affected areas were ear canal $(41\%)$, axillae $(18\%)$, groin $(15\%)$, perianal $(12\%)$, ventral aspect of the neck $(9\%)$, interdigital spaces$(1\%)$, and muzzle $(1\%)$. Sixty seven percent of dogs with MD had cocci. Clinical responses of itraconazole were seen good, moderate, no responses of itraconazole, in $89\%,\;0\%,\;and\;11\%$, respectively, according to the owner's satisfaction to follow up call. Recurrence was detected on five good responsive dogs and adverse effects of the treatment were detected in only one dog. On the basis of this clinical study, itraconazole is a good choice in the treatment of canine Malassezia dermatitis. Efficacy, frequency of administration and veterinary approval are the major advantages.

Malassezia 피부염으로 진단된 18두의 개를 대상으로 Itraconazole 5mg/kg을 1일 2회 경구 투여하여 치료효과를 알아보았다 치료반응을 보인 환자는 $88\%$이었으며 소양감과 피부병면은 치료후 1주일에 확연히 개선되었다. 치료대상견의 품종은 Haltese$(22\%)$, Cocker Sptuiel$(17\%)$, Pekingese$(11\%)$, Vizsla$(11\%)$이었다. 피부증상으로는 가피$(31\%)$, 탈모$(25\%)$, 색소침착$(25\%)$, 인설$(19\%)$, 발적$(13\%)$, 태선화$(11\%)$, 농포$(11\%)$ 귀부종$(11\%)$, 구진$(5\%)$의 순으로 냐타났다. 병변발생부위는 이도$(41\%)$, 액와부$(18\%)$, 서혜부$(15\%)$, 회음부$(12\%)$, 복측경부$(9\%)$, 지간부$(1\%)$, 총구부$(1\%)$ 이었다. 세포학적 검사시$61\%$의 환견에서 구균이 동시에 검출되었다. Itraconazole에 대한 임상반응은 $89\%$가 치료반응을 보였고 (2두)$11\%$는 치료반응을 보이지 않았다 치료반응을 보인 환자 중 5두는 재발되었고 1두는 갑상선 기능저하증이었으며 나머지 4두는 재발의 원인을 확인할 수 없었다. 1두에서 투여 후 28일에 식욕결집, 침울의 증상이 발현되어 투약을 중지하였다. 따라서itraconazole을 5mg/kg을 1일 2회 경구투여는 Malassezia 피부염에 효과적인 치료로 사료된다
