Abstract

Hypoadrenocorticism results from the deficient adrenal gland production of glucocorticoids or mineralocorticoids. Fludrocortisone have been used for the management of hypoadrenocorticism in dogs. But desoxycorticosterone pivalate (DOCP) have been administered for management of hypoadrenocorticism in dogs since several years because of the equivalent effect of fludrocortisone, and lessening of owner and patient's effort. The therapy of DOCP was evaluated in 14 dogs diagnosed with hypoadrenocorticism based on clinical signs, an electrolyte imbalance, and the results of an adrenocorticotropic hormone stimulation test. DOCP was administered at 25-day intervals at an initial dose of 2.2 mg/kg. The dogs were monitored for clinical signs and serum electrolyte, blood urea nitrogen, and creatinine concentrations every 25 days. Fludrocortisone was an effective treatment in dogs overall; however, a change to DOCP was necessary in 7 dogs because of adverse effects or poor responses. Another 7 dogs were treated with DOCP from the first time. A total of 14 dogs were treated with DOCP. Clinical signs and electrolyte imbalance resolved completely in 12 dogs. However, mild clinical signs, such as shivering, remained in 2 dogs, and 4 dogs required regular supplementation with prednisone. Improvements in clinical signs and electrolyte imbalance were significantly better after treatment with DOCP than with fludrocortisone. The results suggest that DOCP may be a better choice than fludrocortisone for the management of hypoadrenocorticism in dogs.

부신피질기능저히증은 부신에서 생산되는 글루코코르티코이드와 미네랄로코르티코이드의 결핍으로 발생한다. 개에서 부신피질기능저하증을 관리하기 위해 fludrocortisone이 사용되어왔다. 그러나 desoxycorticosterone pivalate의 경우 fludrocortisone과 대등한 효과와 보호자와 환자에게 적은 부담을 주기 때문에 최근 몇 년간 부신피질기능저하증 개의 관리를 위해 사용되었다. 임상증상, 전해질불균형, adrenocorticotropic hormone stimulation test를 통하여 부신피질 기능저하증으로 진단된 14마리의 개에서 DOCP의 효과를 분석하였다. DOCP의 초기용량은 2.2 mg/kg 으로 사용되었으며 25일 간격으로 근육 또는 피하로 주사되었다. DOCP의 효능을 보기 위해 25일 간격으로 임상증상, 혈청 전해질 수치, 혈청 요소질소, 크레아티닌 수치를 모니터링 하였다. Fludrocortisones은 개에서 효과적인 치료법이지만 부작용과 불충분한 반응으로 7마리의 개에서 DOCP로의 전환이 필요하였다. 7마리의 개는 처음부터 DOCP가 투약되어 총 14마리의 개가 DOCP로 관리 받았다. 12마리의 개에서 임상증상, 전해질 불균형이 완전히 해소되었으나 2마리의 개에서는 몸 떨림과 같은 약간의 임상증상이 여전히 남아있었다. 4마리의 개는 프레드니손의 정기적 투여가 필요하였다. 이러한 결과를 종합해 보면, fludrocortisone과 비교하여 DOCP가 임상증상과 전해질불균형의 개선에 훨씬 효과적이었으며 이 결과는 부신피질기능저하증 개에서 DOCP가 더 좋은 치료법임을 제시해준다.
