Evaluation of calcium, phosphorus and some biochemical parameters in dogs with open and closed cervix pyometra

The aim of this study was to evaluate the changes in calcium, phosphorus and some biochemical parameters in dogs with open and closed cervix pyometra, which was then compared with a control group. A total of 62 bitches of age group 5-10 years old irrespective of breed were enrolled into the study. Control group consisted of 22 bitches which were clinically healthy and in luteal phase of the estrus cycle. On clinical examination, pyometra was diagnosed in 40 bitches while 23 out of 40 bitches had open-cervix pyometra and 17 of 40 bitches had closed-cervix pyometra. Evaluation of haematological changes revealed that there was increased white blood cell (WBC), total protein (TP), globulin, alkaline phosphatase (ALKP) while decreased glucose (Glu), albumin (Alb) and albumin globulin ratio in pyometra cases (p<0.001). The highest WBC and ALKP levels were detected in closed-cervix pyometra group (p<0.001). Calcium (Ca+2) levels had significant rise in open-cervix pyometra cases (p<0.05) while phosphorus (Phos) levels had tendency to increase in closed-cervix pyometra cases (p=0.08). Also, Ca was directly correlated with Glu, Alb and TP while inversely correlated with WBC and blood urea nitrogen/creatinine (BUN/Crea). However, Phos was significantly associated with BUN and Crea (p<0.001; R=0.915 and R=0.860, respectively). As a result of this study, it was observed that the increased Ca levels in open-cervix cases and the elevated Phos levels in closed-cervix cases, were associated with the biochemical parameters related to hepatic and renal dysfunction in dogs with pyometra.
