cloprostenol and Endometrial-Hyperplasia

Twenty-two bitches with ultrasonographically diagnosed spontaneous pyometra were treated with a combination of 5 microg/kg cabergoline per day and 5 mug/kg cloprostenol every third day, and potentiated sulphonamide twice a day. Bitches with either open-cervix or closed-cervix pyometra showed a rapid clinical improvement, associated with a reduction in plasma progesterone concentration, increased vulval discharge and a reduction in the diameter of the uterus. The haematological profiles of 21 of the bitches returned to normal within six days of treatment, and their biochemical profiles returned to normal within nine days; 19 of the bitches were managed successfully by a 10-day period of treatment. Two bitches required a further three days of treatment, and in one bitch with a partial uterine torsion the treatment was not successful. Adverse effects of the treatment were limited to the 60 minutes immediately after the administration of prostaglandin, and included retching, vomiting, mild abdominal straining, diarrhoea and panting. The incidence of adverse effects was reduced after each successive dose of prostaglandin. Eleven of the 21 successfully treated bitches were mated at the next oestrus, and seven became pregnant; their litters were smaller than the published breed averages. In four of the bitches the pyometra recurred after the next oestrus.

The aim of the study was to evaluate the efficacy of aglepristone (10 mg/kg on days 1, 2 and 8) for the treatment of metritis or pyometra in bitches (n = 67) either alone for cases of metritis (n = 15), or in cases of pyometra (n = 52) with (n = 32) or without (n = 20) the addition of low doses (1 microg/kg) of cloprostenol for 5 days (days 3-7). Examinations performed on day 90, in addition to days 8, 14 and 28, determined that treatments had been curative in the long term in 54/67 bitches (80.6%). Bitches in whom pyometra did not resolve, were given additional aglepristone on day 14 (n = 38) and day 28 (n = 20). Aglepristone alone was curative in 15/15 bitches with metritis. In 17/17 bitches with closed pyometra, cervical opening occurred within 48 h of aglepristone administration. Amongst the 52 bitches with open (n = 35) or closed (n = 17) pyometra, the additional treatment with cloprostenol from days 3 to 7, significantly improved the overall success rate at day 90, which was 27/32 (84.4%), compared to 12/20 (60.0%) in bitches without cloprostenol (P < 0.05). The leucocyte count and plasma progesterone concentrations significantly decreased over the course of treatment. Thirteen of 15 bitches in whom plasma progesterone concentrations were initially low (< 3.18 nmol/L) were cured. The recurrence rate after 12 and 24 months was 13.0% (3/23) and 19.0% (4/21), respectively.

To compare the efficacy and safety of two protocols using a combination of aglepristone and cloprostenol for the treatment of open cervix pyometra in the bitch and to describe the progesterone (P4) serum profiles before and during treatments, 15 bitches were randomly allocated into two treatment groups: I (n = 8): aglepristone was administered at 10mg/kg, s.c., on Days 1, 3, 8, and 15 (if not cured), combined with cloprostenol at the dose of 1 microg/kg, s.c., on Days 3 and 8, and II (n = 7): received the same treatment with aglepristone as Treatment I but cloprostenol on Days 3, 5, 8 10, 12, and 15 (if not cured). Before the beginning of the treatments and then on Days 8, 15, and 29 all bitches were evaluated for clinical signs, side effects, hemogram, serum P4 concentrations, and uterus diameters. Bitches in both treatment groups, with (n = 6) or without (n = 9; > or =1.2 ng/ml) initial basal P4 serum concentrations, achieved treatment success without side effects and no significant differences, either on Day 15 (6/8 for Treatment I and 4/7 for Treatment II) or on Day 29 (2/8 for Treatment I and 3/7 for Treatment II). In both treatments groups, clinical signs, blood parameters, and uterine diameters improved to normal values throughout the experiments. A significant interaction between day and treatment was found for percentage change in P4 when all bitches were considered together. Redevelopment of pyometra in the next estrous cycle occurred in 20% of the bitches. One nonrecurrent bitch was mated and whelped a normal litter. It is concluded that these two combined protocols proved to be efficient and safe in reversing clinical signs of open cervix pyometra independently of initial P4 concentrations and that the number of cloprostenol administrations seemed to have an effect on P4 serum changes throughout treatments.

In the prospective study the authors administered for one year the preparation Klimonorm (Jenapharm) to 90 women divided into three groups. Of 90 patients at the onset 30 women suffered from precancerous endometriosis confirmed by histological and cytological examination. The remaining 60--half with and half without menstrual bleeding--all had climacteric complaints. The authors evaluated by statistical methods various parameters, in particular Kuppermann's index, the thickness of the endometrial mucosa in the uterine cavity by ultrasound, the oncological endometrial cytology by a cytobrush and subsequent lavage of the uterine cavity during 4 check-up examinations after three-month intervals. At the onset of the investigation and after one year the hormonal serum levels (FSH, LH, 17-beta oestradiol) were assessed and in the patients with precancerous conditions also the histology of the endometrium. The results are promising, in particular the significant drop of Kuppermann's index already after three months to one third of the baseline value in all three groups of patients; complete reversal to the negative side as regards the cytological finding on the endometrium, correlating with the histological finding; unaltered body weight; change of the thickness of the endometrium in the group of precanceroses to more favourable values. Based on these results the authors hold the view that hormonal therapy (oestrogen-gestagen) in the climacteric and in endometrial precanceroses is fully justified. Klimonorm (Jenapharm) proved a very useful preparation as the patients' subjective complaints improved and also with regard to the favourable effect on endometrial precanceroses which can be monitored without active abrasion only by a cytobrush.

Cystic endometrial hyperplasia-pyometra complex (CEH/P) is a challenge in canine reproduction. Present study aimed to assess fertility after medical treatment. One-hundred-seventy-four bitches affected by CEH/P received aglepristone on days 1, 2, 8, then every 7 days until blood progesterone < 1.2 ng/mL; cloprostenol was administered on days 3 to 5. Records were grouped according to bodyweight (BW): small (< 10 kg, n = 33), medium (10 ≥ BW < 25 kg, n = 44), large (25 ≥ BW < 40 kg, n = 52), and giant bitches (BW ≥ 40 kg, n = 45). Age; success rate; aglepristone treatments number; relapse, pregnancy rates; diagnosis-relapse, -first, -last litter intervals; litters number after treatment, and LS were analyzed by ANOVA. Overall age was 5.14 ± 1.75 years, without difference among groups. Treatment was 100% successful, without difference in treatments number (4.75 ± 1.18), relapse (15/174, 8.62%) and pregnancy (129/140 litters, 92.14%) rates, intervals diagnosis-relapse (409.63 ± 254.9 days) or -last litter (418.62 ± 129.03 days). The interval diagnosis-first litter was significantly shorter (163.52 ± 51.47 days) and longer (225.17 ± 90.97 days) in small and giant bitches, respectively. Overall, 1.47 ± 0.65 litters were born after treatment. Expected LS was achieved in each group, as shown by ΔLS (actual-expected LS by breed, overall -0.40 ± 1.62) without differences among groups. Concluding, CEH/P affects younger dogs than previously described. Relapses were rarer than previously reported. Medical treatment with aglepristone+cloprostenol is effective and safe, preserving subsequent fertility, as demonstrated by negligible changes in LS.

Cystic endometrial hyperplasia-pyometra (CEH-P) complex is a progesterone-dependent disease that requires medical treatment in bitches intended for breeding. To test the efficacy and safety of a combined protocol and to assess the effect of age, stage of cycle, previous steroid hormone administration and parity on treatment, 29 bitches diagnosed with CEH-P complex were treated daily with cabergoline 5 microg/kg PO and cloprostenol 1 microg/kg SC for 7-14 days, along with supportive antibiotic and hydration therapies. Before treatment, and on Days 3, 7 and 14, all bitches were evaluated clinically and uterine horn diameter measured during trans-abdominal ultrasonography. Twenty-four of 29 bitches were cured by either Day 7 or 14. Nine bitches had mild digestive side effects. Clinical signs related to pyometra began to improve markedly as early as Day 2 of treatment. Uterine diameters decreased (P < 0.05) by Day 3 of treatment, and continued to gradually decrease, reaching normal size by Day 14. Relapses occurred in 6 of 29 cases. Pregnancy was achieved in one of the two young bitches bred after treatment. No significant relationships were found between success rate and age, stage of the estrous cycle, previous hormone administration or parity. Although no variables affecting treatment results could be identified, this combination of compounds was found to be an efficient and safe for treatment of CEH-P.
