At the time of diagnosis, median age was 4.25 yr (range 7 mo to 16 yr), 15 cats (88.2%) had clinical bleeding, and median platelet count was 10,000/μL (range 5000-50,000/μL). All 17 cats were treated with corticosteroids; cyclosporine was additionally prescribed in 14 cats. The median duration of immunosuppressive therapy was 365 days (range 49-2086 days). Thirteen cats achieved a platelet count > 100,000/µL at a median of 15 days (range 2-207 days) following diagnosis of pITP. Only one cat achieved a full remission. A relapse was documented in 10 cats (59%) at a median of 191 days (range 67-1022 days) after diagnosis and 48 days (range 15-196 days) after immunosuppressive medication was reduced or discontinued. Median survival time was 1067 days (range 49-2516 days). No patient, clinicopathological, or treatment variables were identified to affect 3 and 6 mo survival. This study highlights that clinical bleeding is common in cats with pITP, and despite an initial positive response to therapy, it can be difficult to maintain remission.","PeriodicalId":17185,"journal":{"name":"Journal of the American Animal Hospital Association","volume":"62 3","pages":"115-122"},"PeriodicalIF":1.1,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147774841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dog had a history of seizures well controlled by levetiracetam and was genotyped as MDR1 mutant/normal. Ilunocitinib, indicated for controlling pruritus in dogs, was considered. Because the label indicates ilunocitinib can cause cytopenias, a complete blood count (CBC) was performed before initiating treatment. Neutrophils, platelets, and red blood cell numbers were all within reference ranges, so treatment with ilunocitinib was initiated. At a 1 mo follow-up appointment, the dog was bright, alert, and responsive with an improved Pruritus Visual Analog Scale score. A CBC indicated pancytopenia. Ilunocitinib was discontinued and a CBC was repeated after 7 days, indicating resolution of neutropenia and thrombocytopenia, but persisting anemia. One month after discontinuing ilunocitinib, all cytopenias had resolved. Because of the dog's MDR1 genotype, the status of ilunocitinib as a canine P-glycoprotein substrate was assessed. Ilunocitinib was identified as a canine P-glycoprotein substrate. Blunted P-glycoprotein-mediated biliary excretion of ilunocitinib likely resulted in accumulation and a relative overdose. Enhanced penetration of ilunocitinib into hematopoietic stem cells lacking P-glycoprotein expression may have also contributed to dysregulated hematopoiesis. Ilunocitinib should be used cautiously in dogs with P-glycoprotein deficiency.","PeriodicalId":17185,"journal":{"name":"Journal of the American Animal Hospital Association","volume":"62 3","pages":"127-130"},"PeriodicalIF":1.1,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147774757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dog was initially prescribed prednisone at 1 mg/kg q 24 hr and azathioprine at 1.6 mg/kg q 24 hr for immune-mediated polyarthropathy. Over 12 wk, the doses were tapered following clinical remission of immune-mediated polyarthropathy. For an unknown period, owner dosing error suggested a drug overdose of azathioprine at 4.8 mg/kg every other day instead of the prescribed 1.6 mg/kg every other day dose. The drugs were discontinued, and the dog presented for bone marrow failure and associated pancytopenia. Romiplostim was administered at 5 μg/kg subcutaneously on three time points (upon initial presentation to the referral facility, day 8 after initial presentation, and day 15 after initial presentation). Repeat bloodwork at the different time points revealed improvement of the pancytopenia. Romiplostim has been used exclusively for thrombocytopenia in dogs; however, literature in humans and mice models suggests that it can influence multiple cell lines. This case report suggests that romiplostim administration can be considered in cases of pancytopenia and may accelerate bone marrow recovery.","PeriodicalId":17185,"journal":{"name":"Journal of the American Animal Hospital Association","volume":"62 3","pages":"123-126"},"PeriodicalIF":1.1,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147774810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Decontamination was initiated in both dogs. Both dogs were hospitalized and developed sinus tachycardia. Both dogs developed hypotension, with one requiring vasopressor therapy. Both dogs were treated with antiarrhythmic medications and one dog received IV injectable lipid emulsion therapy. Markedly elevated serum cardiac troponin I (TnI) values were reported in both dogs during hospitalization, indicating myocardial damage. Both dogs had resolution of clinical signs by the second day of hospitalization and were discharged. A TnI measurement was obtained in one dog weeks after discharge and was within normal limits, whereas the other showed significant improvement in TnI levels during hospitalization. Minoxidil has long been recognized as a cardiovascular toxin in dogs and cats. Existing reports of minoxidil toxicosis in pets involve the topical formulation of the drug. To the authors' knowledge, this is the first report of toxicity involving the oral formulation of minoxidil and the first reported instance of minoxidil-related acute myocardial injury with clinical resolution and marked reduction in TnI levels.","PeriodicalId":17185,"journal":{"name":"Journal of the American Animal Hospital Association","volume":"62 3","pages":"131-135"},"PeriodicalIF":1.1,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147774768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies suggest that postoperative radiation therapy can be effective for spinal meningiomas. Information on radiation-induced complications and prognosis remains limited. This case series evaluated treatment outcomes of surgical and radiation therapy in dogs with spinal meningiomas. Ten dogs were included. All underwent surgery, and histopathological examination confirmed meningioma. Among the four cases where surgical margins were assessed, three had incomplete resections. Postoperative radiation therapy was administered as an adjuvant treatment in nine dogs. One dog that did not receive postoperative radiation underwent radiation upon recurrence, observed at 99 days postsurgery. The radiation protocol consisted of fractionated irradiation (32-55 Gy/12-21 fractions) delivered five times per week. During the observation period, nine of 10 dogs died, with a median survival time of 568 days (range: 165-1823 days). Local recurrence occurred in six dogs at 95, 99, 153, 367, 433, and 1086 days postoperatively, confirmed by magnetic resonance imaging.

The dog exhibited lameness in the right pelvic limb, with a varus deformity of the distal tibia and grade 2 lateral patellar luxation. Radiographic and computed tomography imaging confirmed the presence of varus in the distal diaphyseal portion of the right tibia, without procurvatum or internal torsion. Medial opening wedge osteotomy and free-form bilateral multiplanar ESF successfully corrected the deformity. Dynamization was performed by removing the lateral column 3 mo after surgery, followed by the removal of all transfixation pins and the medial column under sedation 4 mo after surgery. The dog remained free of clinical signs at the last follow-up 24 mo after surgery, although residual pin tract holes were evident on radiographs. Free-form bilateral multiplanar ESF is an alternative rigid fixation method for pes varus correction, allowing technically simple relative to plate fixation, three-dimensional precise adjustments, and staged dynamization.","PeriodicalId":17185,"journal":{"name":"Journal of the American Animal Hospital Association","volume":"62 2","pages":"54-60"},"PeriodicalIF":1.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147317535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
