Alopesili erkek köpeklerde düşük testesteron seviyelerinin incelenmesi

Kedi ve köpeklerde nadir olarak saptanmasına rağmen hipoandrojenizm insanlardaki alopesinin nedenlerinden birisidir. Yazarların bilgisine göre, bu çalışma erkek köpeklerde sadece hipoandrojenizmin anamnez ve klinik belirtilerini açıklayan ilk retrospektif rapordur. 1999 ile 2017 yılları arasında farklı ırk ve yaş gruplarında 76 erkek köpeğin tıbbi kayıtları retrospektif olarak incelendi ve çalışma kapsamında değerlendirildi. En sık görülen klinik bulgular, kuyruktan boyun bölgesine kadar uzayan alopesi ve hiperpigmentasyondu. Bu çalışma, erkek köpeklerde hipoandrojenizmi olan çeşitli kutanöz lezyonları tanımlamıştır. Hayvanlarda hipoandrojenizmi tanımlayan nispeten az yayınlanmış bilgi olduğu için, bu endokrinopatilerin önemini anlamak için daha fazla çalışmaya ihtiyaç vardır.

Evaluation of Low Testesterone Levels in Male Dogs with Alopecia

Hypoandrogenism is one of the reasons for alopecia in humans, however it is rarely detected in dogs and cats. To the best of the authors’ knowledge, this is the first retrospective report describing only signalment and clinical manifestations of hypoandrogenism in male dogs. A retrospective review of the medical records of 76 male dogs of different breeds and ages with hypoandrogenism from 1999 to 2017 were included to the study. The most common clinical signs were alopecia that started from the tail to the neck and hyperpigmentation. This study identified a variety of cutaneous lesions in male dogs with hypoandrogenism. As there is relatively little published information describing hypoandrogenism in animals, further studies are required to understand the importance of these endocrinopathies.
