title: Effectiveness of a modified administration protocol for the medical treatment of canine pyometra.
abstract: Pyometra is one of the most common diseases in intact bitches. The aim of this study was to evaluate the effectiveness of a modified aglepristone protocol for the medical treatment of pyometra in the bitch. Of these, 73 bitches affected by pyometra of different breeds and age (2-14 years old) were enrolled. They were randomly assigned to a control group (CTG - 26 bitches) treated with classical protocol (aglepristone at 0, 1 and 6 days - day 0 = day of the diagnosis) and a modified treated group (MTG - 47 bitches) treated with a different administration protocol (aglepristone at 0, 2, 5 and 8 days). The classical protocol with the anti-progestagen aglepristone was effective in 88.5 % (23/26) of CTG bitches while the modified protocol was effective in all (47/47) of MTG bitches. One of the 23 CTG bitches received a further administration on day 14, which resolved the pyometra, while in the three cases of CTG bitches, in which the treatment was ineffective, an ovariohysterectomy was carried out. The modified protocol showed a success rate of 100 %, compared with the classical protocol proposed in the literature, and no recurrence of the disease was recorded in the 24 months follow up. After treatment, the oestrus onset was earlier than expected (interoestrus of 128 ± 32 days). In this study, the modified treatment protocol showed high efficacy and lack of recurrence within 24 months, suggesting a complete recovery of reproductive function in the bitch, with a normal fertility.
