Multi-organ damage in a cow with diabetes mellitus

Abstract

A clinical, hematological and pathological study was carried out on a bovine case of diabetes mellitus (DM) presenting clinical sings of polydipsia, polyuria, glycosuria, hyperglycemia, progressive emaciation and decreased milk yield. The body temperature, heart and respiratory rates were in normal range. Also there was no significant change in hematological values. Prior to slaughter; blood and urine samples were taken twice 48 hour interval from the cow. At necropsy, liver was pale and enlarged. Multiple small white foci were observed on the cortical area of the kidneys. Lung edema and foamy exudates in the lumen of the trachea and bronchus was present. At the gross examination pancreas was in normal appearance. Histopathologically reduced number and size were observed at the pancreatic islet localized in all pancreatic lobes. Decreased cell number observed in the Langerhans islets. Vacuolization and degenerations at the beta cells were commonly seen. Immunohistochemical study of pancreatic tissue revealed a marked reduction in the concentration and distribution of insulin, proinsulin, and amylin, but an increase in glucagon secreted cells. According to the clinical, histopathological and immunohistochemical findings, a combination of diabetes mellitus and multiorgan damage were diagnosed in a cow

Diabetes mellituslu bir inekte çoklu organ hasarı

Abstract

Çok su içme, çok idrar yapma, ilerleyen zayıflama ve süt veriminde azalma şikayetleri ile kliniğe getirilen diyabetli bir inekte klinik, hematolojik ve patolojik incelemeler yapıldı. Hayvanın vücut ısısı, kalp ve solunum sayıları normal sınırlar içerisindeydi. Ayrıca hemogram muayenede de önemli bir bulguya rastlanmadı. İnek kesime gitmeden önce 48 saat arayla 2 defa kan ve idrar numunesi toplandı. Nekropside, karaciğer büyümüş ve soluk renkliydi. Böbreklerin kortikal bölgelerinde çok sayıda beyaz renkli ve küçük odak saptandı. Akciğerlerde ödem, trahea ve bronş lumenlerinde köpüklü eksudat vardı. Dış bakıda pankreas normal görünümdeydi. Histopatolojik incelemede bütün pankreatik loplarda pankreatik adacık sayısı ve boyutunda azalma gözlendi. Langerhans adacıklarında hücre sayısının azaldığı saptandı. Genel olarak beta hücrelerinde vakuolizasyon ve dejenerasyonlar sıklıkla dikkati çekti. Pankreatik dokunun immunohistokimyasal muayenesinde insülin, proinsülin ve amilin sentezleyen hücrelerde belirgin bir azalma olduğu, buna karşın glukagon sentezleyen hücrelerde bir artış olduğu gözlendi. Klinik, histopatolojik ve immunohistokimyasal bulgulara dayanarak diabetes mellitus ve çoklu organ hasarı teşhisi konuldu
