- Pain treatment of lactating bitches is a clinically relevant, but complicated issue. Published scientific studies regarding the excretion of drugs in canine milk are scarce. When considering the risk of side effects in their offspring, lactating bitches have traditionally received very restricted analgesic and anti-inflammatory therapy. Our aim was to quantify the concentrations of carprofen in milk from lactating bitches and relate those to potential risks for the puppies. A second aim was to evaluate the impact mastitis may have on the concentration of carprofen in milk. A population of 100 bitches was enrolled in the study, among which 88 were bitches treated with carprofen after cesarean section (Group CS), eight were bitches with painful inflammatory conditions (Group I) and four were bitches with mastitis (Group M). The patients enrolled in the study received carprofen 4 mg/kg sc at day 1 followed by 2 mg/kg po every 12 h for the following 2-5 days. Owners were instructed to collect milk once a day for five days. The concentration of carprofen in the milk was quantified with ultra-performance liquid chromatography-tandem mass spectrometry. The data obtained were statistically analyzed as repeated-measures data with a mixed-model approach. Data were used to calculate the theoretical maximum total daily intake of carprofen by the puppies in order to perform a computerized simulation of the plasma concentration of carprofen in the puppies. Follow-up telephone interviews to check the status of the enrolled bitches and their litters occurred at one week and three-six months after treatment with car-profen. The major finding of the study was that the concentration of carprofen in the milk was <700 ng/ mL from bitches undergoing CS or suffering painful conditions other than mastitis. In comparison, administration of 2 mg/kg of carprofen sc or po to adult dogs, results in mean maximal plasma con-centrations of 19480 +/- 5420 ng/mL (mean +/- SD). Moreover, data suggests that inflammation of the mammary gland results in a higher concentration of carprofen in milk (up to 1300 ng/mL). In the computerized simulation, the plasma concentrations of carprofen in puppies in group CS and in group I are one tenth of the concentration in adult dogs receiving carprofen at standard doses. Considering the low excretion into milk, carprofen provides an analgesic alternative to lactating bitches without mastitis.(c) 2022 Published by Elsevier Inc.

- Background: Sepsis is a serious and potentially life-threatening condition and early diagnosis and appropriate treatment is crucial for survival. Pyometra is one of the most common diseases in intact female dogs. The disease often leads to sepsis (systemic inflammatory response syndrome, SIRS, caused by infection). Diagnostic markers for detecting sepsis are gaining increasing interest in veterinary medicine. Acute phase proteins (APPs) such as C-reactive protein (CRP) are useful for detecting systemic inflammation in dogs. Serum amyloid A (SAA) is another major APP in dogs that is not yet as widely used. Albumin is regarded as a negative APP and has earlier been evaluated for prediction of prognosis in septic dogs. The aim of the present study was to determine SAA, CRP and albumin concentrations in dogs with sepsis and pyometra and to evaluate whether these inflammatory markers are associated with length of postoperative hospitalization.Results: Thirty-one surgically treated bitches with pyometra were included, whereof 23 septic (SIRS-positive) and eight non-septic (SIRS-negative). Albumin concentrations were analyzed by routine automated methods. SAA and CRP analyses were performed with previously validated commercially available assays (ELISA and immunoturbidimetric). Mean (+/- SE) serum concentrations of SAA were significantly higher in septic (130.8 +/- 8.0 mg/L) compared to non-septic bitches (88.5 +/- 12.5 mg/L). Using a cut-off value for SAA of 109.07 mg/L (n = 31 bitches), the sensitivity and specificity for detecting sepsis was 74% and 50%, respectively. Serum albumin concentrations were not significantly different in septic compared to non-septic bitches (mean +/- SE, 25 +/- 1 g/L and 26 +/- 1 g/L, respectively). CRP concentrations were also not significantly different in septic (mean +/- SE 225.6 +/- 16.0 mg/L) compared to non-septic bitches (mean +/- SE, 176.0 +/- 27.1 mg/L). None of these inflammatory markers were associated with the outcome as measured by length of hospitalization.Conclusions: SAA concentrations were increased in dogs with sepsis induced by pyometra and may be useful as an adjunctive diagnostic marker for sepsis. To evaluate the full potential of SAA as a marker for sepsis also in other diseases, further studies are warranted.

- Objective: whether this is repeated during removal of the 2nd ovary in elective ovariohysterectomy.To investigate the physiologic reactions after removal of 1st ovary and Study Design:Prospective study. Animals:Dogs (n¼10). Methods: anesthetized with propofol and iso iso during surgery on physiologic variables were analyzed using mixed linear models. Blood and urine samples were collected before anesthesia, before incision, before and after removal of ovaries with a 15 minute pause between ovary removal, and after abdominal closure. Plasma vasopressin and urinary noradrenalin and creatinine concentrations were analyzed.Dogs were premedicated with acepromazine, carprofen, and methadone andflurane. Blood pressure, heart rate, and end‐tidalflurane concentration were measured every minute. The effects of various events Results: greater than for the 2nd ovary because of an elevation in baseline. Similarly, the heart rate increased at the removal of the 1st ovary but not at removal of the 2nd ovary. Plasma vasopressin concentration increased at removal of both ovaries. Urinary noradrenalin/ creatinine ratio increased at anesthesia, removal of both ovaries, and was elevated at closure of the abdomen. End pressure and vasopressin concentrations changed in parallel using z comparison.The magnitude of blood pressure increase at removal of the 1st ovary was‐tidal isoflurane concentration did not change. Blood‐scores for Conclusions: concentration, and urinary noradrenalin/creatinine ratio did not differ between removals of the ovaries. Relative changes differed between repeated noxious stimuli, which should be considered in evaluation of methods at ovary removal.Peak values for blood pressure, heart rate, plasma vasopressin

- Pyometra is a common and life-threatening disease of intact bitches caused by hormonal influence of the uterus in combination with bacterial infection. The treatment of choice is ovariohysterectomy, but several purely medical options are available. Common drugs used for medical treatment in combination with antimicrobials are progesterone receptor blockers, prostaglandins, and dopamine agonists. The aim of this study was to evaluate long-term recovery and fertility after treatment with the progesterone receptor blocker aglepristone in bitches with pyometra. Data from 28 bitches with pyometra, admitted to the University Animal Hospital, Swedish University of Agricultural Sciences, during a 9-year period, were studied retrospectively and followed up by telephone interviews with the owners. The bitches had been treated with aglepristone at a dose of 10 mg/kg on a median of four occasions. All bitches had also been treated with antimicrobial drugs for a mean duration of 23 days, the most frequently used being enrofloxacin. Escherichia coli were the most commonly isolated bacteria from cranial vagina. The outcome was assessed for up to 6 years after treatment. The success rate, determined as restored clinically healthy status, was 75% (21/28 bitches), and the recurrence rate of disease was 48% (10/21 bitches). The mean time until recurrence was 10.5 months after the end of treatment. After treatment, 69% (9/13) of the mated bitches produced puppies. Of the seven bitches that did not have a successful treatment, six were ovariohysterectomized and one was euthanized. In conclusion, medical treatment with aglepristone in combination with antimicrobial therapy was successful in 75% of the bitches studied and the recurrence rate was 48%. (C) 2014 The Authors.
