Anemia in cats with hemotropic mycoplasma infection: retrospective evaluation of 23 cases (1996-2005)
Abstract
This study summarizes the diagnostic findings from all anemic cats diagnosed with hemotropic mycoplasma (HM) infections at the Western College of Veterinary Medicine-Veterinary Teaching Hospital between 1996 and 2005. The objectives were to determine the frequency of HM-induced anemia among all cats presented with anemia during this period, the clinical findings and risk factors associated with clinical HM infection, and factors affecting or predicting survival. Medical records were examined from 23 cats with HM-induced anemia from the total of 170 cats diagnosed with anemia during this period. The frequency of HM-induced anemia was 14% (23/170) among all anemic cats. Cats with HM-induced anemia were less likely to be purebred (P = 0.04) than other cats with anemia. Of the cats with HM-induced anemia, those with positive retroviral status (P = 0.01), concurrent illness (P < 0.01), or lack of erythroid regeneration (P = 0.01) were most likely to die. The 1-year survival of HM-infected cats was 65% (13/20).
Anémie chez les chats atteints d’une infection aux mycoplasmes hémotropes : Évaluation rétrospective de 23 cas (de 1996 à 2005). Cette étude résume les résultats diagnostiques de tous les chats anémiques diagnostiqués avec des infections aux mycoplasmes hémotropes (MH) à l’hôpital d’enseignement vétérinaire du Western College of Veterinary Medicine de 1996 à 2005. Les objectifs consistaient à déterminer la fréquence de l’anémie induite par les MH parmi tous les chats présentés avec de l’anémie durant cette période, les résultats cliniques et les facteurs de risque associés à l’infection clinique aux MH ainsi que les facteurs affectant ou prédisant la survie. Les dossiers médicaux de 23 chats atteints d’anémie induite par MH ont été examinés parmi un total de 170 chats diagnostiqués avec l’anémie durant cette période. La fréquence de l’anémie induite par MH était de 14 % (23/170) parmi tous les chats anémiques. Il était moins probable que les chats avec de l’anémie induite par MH étaient des chats de race (P = 0,04) que les autres chats anémiques. Parmi les chats atteints de l’anémie induite par MH, la mort était plus probable chez ceux avec un statut rétroviral positif (P = 0,01), une maladie concomitante (P < 0,01) ou l’absence de régénération érythrocytaire (P = 0,01). Le taux de survie après 1 an des chats infectés par MH était de 65 % (13/20).
