Xanthinuria secondary to allopurinol treatment in dogs with leishmaniosis: current perspectives of the Iberian veterinary community

Research Areas: Immunology ; Microbiology ; Veterinary SciencesXanthinuria is a significant adverse effect in dogs on long-term allopurinol for treatment of leishmaniosis. The study aims to investigate how the Iberian veterinary community (IVC) identifies, manages, and proactively prevents xanthinuria secondary to allopurinol treatment. A cross-sectional study was conducted using an online survey, translated into two languages, and disseminated to the IVC via social networking forums. Respondents were asked to share their treatment regimens, adverse effects attributed to treatment, as well as preventive and reactive measures against xanthuria. Of two-hundred and thirty respondents, 99.6% prescribe allopurinol for canine leishmaniosis. Xanthinuria was estimated to happen in less than one out of every four dogs by 91.7% of the clinicians. Xanthinuria has been detected by 71.6% of respondents at least once. Three out of every four respondents inform owners about deleterious effects of allopurinol, and 28.4% consider implementing a change in diet in advance of treatment as a proactive measure. To monitor xanthinuria, urinalysis and diagnostic imaging are used by 71.2% and 31% of clinicians respectively. When xanthinuria is detected, 43.2% of the respondents discontinue allopurinol, 24% replace it by nucleotide-analogs, 14.9% reduce its dosage, and 3.1% split its dosage but increase administration frequency. Additional measures are taken by 72.1% of the respondents, 59.4% of whom prescribe a low-purine diet. The IVC recognizes xanthinuria as a fairly common secondary effect of long-term allopurinol treatment in dogs with leishmaniosis and recommends periodically monitoring and preventive measures.info:eu-repo/semantics/publishedVersio

Ultrasonographic detected adrenomegaly in Clinically Ill Cats: a retrospective study

This retrospective study aimed to assess the prevalence of ultrasonographic detected adrenomegaly in clinically ill cats, evaluating the final established diagnosis, describe adrenal ultrasound findings and if the adrenomegaly was suspected or incidental. Abdominal ultrasonography reports of cats presenting to a veterinary teaching hospital between October 2018 and February 2021 were retrospectively reviewed. Cats showing adrenomegaly (one or both glands having a dorsoventral axis >4.8 mm) were selected and medical records respectively evaluated. Nine-hundred and eighty-three ultrasonographical reports were selected, of which, 68 (7%) disclosed adrenomegaly. European/Domestic Short-Hair (62/68; 91%) male (44/68; 65%) castrated (35/44; 80%) cats were overrepresented. Adrenomegaly was an incidental finding in 62/68 (91%) cats while in 6/68 (9%) it was identified in the context of investigating a potential adrenal disease. Concerning established diagnosis, chronic kidney disease was overrepresented (25/68; 37%), followed by endocrinopathies (20/68; 29%). Adrenomegaly was bilateral in 53% (36/68) of cases. In unilateral cases (32/68; 47%), it was more prevalent on the left side (23/32; 72%), with a normal-sized contralateral adrenal gland. Left adrenal demonstrated a larger size and a tendency to oval shape. This study assesses the prevalence of adrenomegaly in clinically ill cats, reinforcing it can be an incidental ultrasound finding.info:eu-repo/semantics/publishedVersio

Nasal foreign bodies identified by rhinoscopy in dogs: 42 cases

Objective To evaluate signalment, clinical presentation, location and type of nasal foreign bodies identified by rhinoscopy in dogs. Materials and Methods We retrospectively reviewed medical records from dogs that presented for consultation between April 2012 and June 2019 and were diagnosed with nasal foreign body via rhinoscopy. Results Forty-two dogs met the study's inclusion criteria. Thirty (71.4%; 30/42) were purebreds. Males accounted for 59.5% (25/42) of cases. The median age was 4.0 years old and 76.2% (32/42) were dogs up to 7 years of age. Mean bodyweight was 21.8 kg and dogs weighing more than 10 kg were overrepresented (78.6%; 33/42). Sneezing occurred in 78.6% (33/42) of cases. Foreign body retrieval was achieved by rhinoscopy in all cases. The foreign body was extracted from the right nasal cavity in 52.4% (22/42) of cases and from the left one in 42.9% (18/42). Two dogs (4.8%; 2/42) presented with one foreign body in each nasal cavity. Most nasal cavity foreign bodies (90.5%; 38/42) were grass awns. Three (7.2%; 3/42) were mineral and one (1/42) was fabric. Follow-up was documented for 35 patients, of which 97.1% (34/35) experienced resolution of clinical signs. Seven cases (16.7%; 7/42) were lost to follow-up. Clinical Significance Nasal foreign bodies were more common in dogs up to 7 years of age and heavier than 10 kg. Sneezing was the primary clinical sign. The vast majority of foreign bodies were grass awns and rhinoscopy was an effective means of nasal cavity foreign body retrieval.12 month embargo; first published 28 September 2020This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Clinical findings and prognostic factors for mortality in hospitalized dogs with leishmaniosis: a retrospective study

This retrospective study evaluated factors responsible for mortality of dogs hospitalized for Canine Leishmaniosis. Medical records of 31 dogs with leishmaniosis from a Portuguese Veterinary Teaching Hospital were examined between August 2018 and January 2022. Females (n = 18) and pure breed dogs (n = 27) were overrepresented, with higher frequency of Labrador Retriever (n = 4). Median age was 7 years (interquartile range=7). Most had historical findings of lethargy (n = 26) and the commonest clinicopathological abnormality was hypoalbuminemia (n = 26). Eleven dogs were classified as LeishVet stage II, 10 stage III and 10 stage IV. Fourteen dogs (45.2%) died or were euthanized, with azotemia, leukocytosis, stage IV, absence of diagnosis before hospitalization and lack of leishmaniosis specific treatment during hospitalization contributing to mortality. Absence of hypoalbuminemia and stages II/III increased survival. Mean hospitalization length prior to discharge was 5.41 days ( ± 1.84) and diarrhea prolonged hospital stay.Open access articleThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Use of Deoxycorticosterone Pivalate by Veterinarians: A Western European Survey

This study aims to gather knowledge about the use of deoxycorticosterone pivalate (DOCP) by Western European Veterinarians (WEV) in dogs with typical hypoadrenocorticism. An observational cross-sectional study was conducted using an online survey, translated into four languages and disseminated to veterinary affiliates and mailing lists in six countries of Western Continental Europe. Respondents were tasked to share their therapeutic approach to hypoadrenocorticism, whether they preferred DOCP or fludrocortisone and the specific practical use of DOCP. One-hundred and eighty-four responses were included. Of these, 79.9% indicated that they preferred prescribing DOCP over fludrocortisone as a first-line treatment for mineralocorticoid supplementation. A total of 154 respondents had used DOCP at least once. Eighty percent of those who reported their initial dosage prescribed 2.2 mg/kg. After starting DOCP, 68.2% of the respondents assess electrolytes 10 and 25 days after administration following manufacturer instructions. In stable dogs, electrolytes are monitored quarterly, monthly, semi-annually, and annually by 44.2%, 34.4%, 16.9%, and 4.6% of respondents respectively. When treatment adjustment is required, 53% prefer to reduce dosage while 47% increase the interval between doses. Overall, DOCP is the preferred mineralocorticoid supplementation among WEV. Reported variability underlies the need to investigate the best strategies for DOCP use and therapeutic adjustments
