The aim of this study was to evaluate the impact of epilepsy in dogs on their owners, utilizing an online survey tool. A questionnaire was developed to explore a variety of factors, including seizure history, treatment, outcome, quality of life, costs associated with therapy, and sources of support. A total of 225 responses were obtained. The majority of respondents reported positive scores for overall quality of life, although scores were significantly lower for dogs with poorly controlled epilepsy and medication-related adverse effects. The median monthly expenditure for antiepileptic medication was $51–75. Despite the considerable financial burden placed on the dog owner, monthly medication cost was not associated with quality of life score. Few published reports follow dogs with epilepsy after diagnosis, and there is a growing need to understand the issues associated with long-term management of this population. The results of this study provide useful information that can help veterinary professionals educate owners and set expectations regarding treatment of seizures and quality of life for dogs with epilepsy.}, number={3}, journal={JOURNAL OF THE AMERICAN ANIMAL HOSPITAL ASSOCIATION}, author={Nettifee, Julie A. and Munana, Karen R. and Griffith, Emily H.}, year={2017}, pages={143–149} } @article{gieger_nettifee-osborne_hallman_johannes_clarke_nolan_williams_2017, title={The impact of carboplatin and toceranib phosphate on serum vascular endothelial growth factor (VEGF) and metalloproteinase-9 (MMP-9) levels and survival in canine osteosarcoma}, volume={81}, number={3}, journal={Canadian Journal of Veterinary Research}, author={Gieger, T.

Concurrent phenobarbital administration alters the disposition of LEV in healthy dogs.Hypothesis/ObjectivesTo evaluate the pharmacokinetics of LEV in dogs with epilepsy when administered concurrently with conventional AEDs.AnimalsEighteen client‐owned dogs on maintenance treatment with LEV and phenobarbital (PB group, n = 6), LEV and bromide (BR group, n = 6) or LEV, phenobarbital and bromide (PB–BR group, n = 6).MethodsProspective pharmacokinetic study. Blood samples were collected at 0, 1, 2, 4, and 6 hours after LEV administration. Plasma LEV concentrations were determined by high‐pressure liquid chromatography. To account for dose differences among dogs, LEV concentrations were normalized to the mean study dose (26.4 mg/kg). Pharmacokinetic analysis was performed on adjusted concentrations, using a noncompartmental method, and area‐under‐the‐curve (AUC) calculated to the last measured time point.ResultsCompared to the PB and PB–BR groups, the BR group had significantly higher peak concentration (Cmax) (73.4 ± 24.0 versus 37.5 ± 13.7 and 26.5 ± 8.96 μg/mL, respectively, P < .001) and AUC (329 ± 114 versus 140 ± 64.7 and 98.7 ± 42.2 h*μg/mL, respectively, P < .001), and significantly lower clearance (CL/F) (71.8 ± 22.1 versus 187 ± 81.9 and 269 ± 127 mL/h/kg, respectively, P = .028).Conclusions and Clinical ImportanceConcurrent administration of PB alone or in combination with bromide increases LEV clearance in epileptic dogs compared to concurrent administration of bromide alone. Dosage increases might be indicated when utilizing LEV as add‐on treatment with phenobarbital in dogs.}, number={2}, journal={JOURNAL OF VETERINARY INTERNAL MEDICINE}, author={Munana, K.

Design—Retrospective case series. Animals—214 client-owned dogs with onset of epileptic seizures at ≥ 7 years of age. Procedures—A diagnostic imaging database was searched for dogs with symptomatic or cryptogenic epilepsy. Signalment, seizure history, and diagnostic information were recorded. Information regarding seizure frequency, administration of antiepileptic drugs (AEDs), owners' perceptions regarding quality of life, survival times, and causes of death for dogs with cryptogenic epilepsy was obtained via questionnaire. Variables were compared among dogs grouped according to diagnosis and age. Results—45 (21%) dogs had a diagnosis of cryptogenic epilepsy, and 169 (79%) had symptomatic epilepsy. In dogs 7 to 9 years and ≥ 10 years of age at the time of seizure onset, 31 of 106 (29%) and 14 of 108 (13%), respectively, had a diagnosis of cryptogenic epilepsy. At last follow-up, most (40 [89%]) dogs with cryptogenic epilepsy were receiving ≥ 1 AED. Thirty-one of 37 (84%) dogs typically had ≤ 1 seizure/mo following hospital discharge. Death was confirmed in 20 (44%) dogs with cryptogenic epilepsy and was related to seizures or AEDs in 7 Median survival time from onset of seizures was 52 months for all dogs with cryptogenic epilepsy. Median quality-of-life score (scale, 1 [poor] to 10 [excellent]) indicated by 34 owners of dogs with cryptogenic epilepsy was 10 before diagnosis and initiation of AED treatment and 8 afterward. Conclusions and Clinical Relevance—Cryptogenic epilepsy was diagnosed in a substantial proportion of dogs with an onset of epileptic seizures at ≥ 7 years of age. Seizure control was considered acceptable in most dogs.}, number={5}, journal={JAVMA-JOURNAL OF THE AMERICAN VETERINARY MEDICAL ASSOCIATION}, author={Schwartz, Malte and Munana, Karen R. and Nettifee-Osborne, Julie}, year={2013}, month={Mar}, pages={651–657} } @article{munana_thomas_inzana_nettifee-osborne_mclucas_olby_mariani_early_2012, title={Evaluation of Levetiracetam as Adjunctive Treatment for Refractory Canine Epilepsy: A Randomized, Placebo-Controlled, Crossover Trial}, volume={26}, ISSN={["1939-1676"]}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-84858746170&partnerID=MN8TOARS}, DOI={10.1111/j.1939-1676.2011.00866.x}, abstractNote={BackgroundThere is little evidence‐based information available to guide treatment of refractory epilepsy in dogs. The antiepileptic drug levetiracetam (LEV) is administered to dogs, although its safety and efficacy are unknown.ObjectiveTo evaluate the safety and efficacy of LEV as adjunctive therapy for refractory epilepsy in dogs.AnimalsThirty‐four client‐owned dogs with idiopathic epilepsy.MethodsRandomized, blinded trial involving dogs resistant to phenobarbital and bromide. Dogs received LEV (20 mg/kg PO q8h) or placebo for 16 weeks, and after a 4‐week washout were crossed over to the alternate treatment for 16 weeks. Owners kept records on seizure frequency and adverse events. Hemogram, chemistry profile, urinalysis, and serum antiepileptic drug concentrations were evaluated at established intervals.ResultsTwenty‐two (65%) dogs completed the study. Weekly seizure frequency during the 1st treatment period decreased significantly during LEV administration relative to baseline (1.9 ± 1.9 to 1.1 ± 1.3, P = .015). The reduction in seizures with LEV was not significant when compared to placebo (1.1 ± 1.3 versus 1.5 ± 1.7, P = .310). The most common adverse event was ataxia, with no difference in incidence between LEV and placebo (45 versus 18%, P = .090). No changes in laboratory parameters were identified and owners reported an improved quality of life (QOL) with LEV compared to placebo (QOL score 32.7 ± 4.3 versus 29.4 ± 4.5, P = .028).Conclusions and Clinical ImportanceAdjunctive treatment with LEV appears safe in epileptic dogs. Efficacy of LEV over placebo was not demonstrated, although the power of the study was limited. Further evaluation of LEV as treatment for epilepsy in dogs is warranted.}, number={2}, journal={JOURNAL OF VETERINARY INTERNAL MEDICINE}, author={Munana, K. R. and Thomas, W. B. and Inzana, K.

This study compared the pharmacokinetics of midazolam after intravenous (IV), intramuscular (IM), and rectal (PR) administration. Six healthy dogs were administered 0.2 mg/kg midazolam IV, IM, or PR in a randomized, 3‐way crossover design with a 3‐day washout between study periods. Blood samples were collected at baseline and at predetermined intervals until 480 min after administration. Plasma midazolam concentrations were measured by high‐pressure liquid chromatography with UV detection. Rectal administration resulted in erratic systemic availability with undetectable to low plasma concentrations. Arithmetic mean values ± SD for midazolam peak plasma concentrations were 0.86 ± 0.36 μg/mL (C0) and 0.20 ± 0.06 μg/mL (Cmax), following IV and IM administration, respectively. Time to peak concentration (Tmax) after IM administration was 7.8 ± 2.4 min with a bioavailability of 50 ± 16%. Findings suggest that IM midazolam might be useful in treating seizures in dogs when venous access is unavailable, but higher doses may be needed to account for intermediate bioavailability. Rectal administration is likely of limited efficacy for treating seizures in dogs.}, number={5}, journal={JOURNAL OF VETERINARY PHARMACOLOGY AND THERAPEUTICS}, author={Schwartz, M. and Munana, K.
