topiramate and Renal-Insufficiency--Chronic

Patients with POAG have lower corneal endothelial cell density than healthy controls of the same age. This may be attributed to mechanical damage from elevated IOP and toxicity of glaucoma medications.. Mycophenolic acid was detected in all cats. The dose 10 mg/kg given q12h for 1 week was tolerated (n = 3). The efficacy of MMF as an immunosuppressant and long-term safety in cats of this dosage regimen is unknown.. T

Capgras delusion (CD) has multiple etiologies including neurodegenerative disorders and can be associated with violent behavior. CD is a common complication of Alzheimer dementia (AD); however, CD with violent behavior is uncommon in AD. We report escalating violent behavior by a patient with advanced AD and CD who presented to the emergency department (ED) and required admission to an academic medical center.. Case analysis with PubMed literature review.. A 75-year-old male with a 13-year history of progressive AD, asymptomatic bipolar disorder, chronic kidney disease, hypertension, hyperlipidemia, and benign prostatic hypertrophy presented to the ED with recurrent/escalating violence toward his wife, whom he considered an impostor. His psychotropic regimen included potentially inappropriate medications (PIMs) for geriatric/AD patients-topiramate/amitriptyline/chlordiazepoxide/olanzapine-that are associated with delirium, cognitive decline, dementia, and mortality. Renal dosing for topiramate, reduction in PIMs/anticholinergic burden, and substituting haloperidol for olanzapine resolved his violent behavior and CD.. CD in AD is a risk factor for violent behavior. As the geriatric population in the United States grows, CD in patients with AD may present more frequently in the ED, requiring proper treatment. Pharmacovigilance is necessary to minimize PIMs in geriatric/AD patients. Clinicians and other caregivers require further education to appropriately address CD in AD.

Guidelines on the use of dialysis treatment in patients with chronic kidney disease (CKD) and TPM (Topiramate) intoxication are controversial. A 51-year-old man with epilepsy and CKD was carried to our emergency department for dysuria and sickness. He chronically assumed TPM 100 mg 3/day. Creatinine level was 2.1 mg/dL, blood urea nitrogen 70 mg/dL, and inflammation indexes were increased. We started empirical antibiotic therapy and rehydration. The day two he had diarrhea and an acute insurgence of dizziness, confusion, and bicarbonate levels reduction. Brain CT resulted negative for acute events. During the night his mental status worsened, and urinary output results were about 200 mL in 12h. EEG showed desynchronized brain bioelectric activity. Thereafter, there was an episode of seizure and then anuria, hemodynamic instability, and loss of consciousness. Creatinine value was 5.39 mg/dL with a serious metabolic acidosis non-anion gap. We decided to start 6-hours Sustained Low Efficiency Hemo-Dia-Filtration (SLE-HDF). We assisted in the recovery of consciousness and later in the improvement of kidney function after 4 hours of treatment. TPM levels before SLE-HDF resulted in 123.1 µg/mL. At the end of treatment resulted in 30 µg/mL. To our knowledge, this is the first report of TPM involuntary intoxication in a patient affected by CKD who survived such a high TPM concentration treated with renal replacement therapy. SLE-HDF resulted in moderate elimination of TPM and acidemia resolution, continuous monitoring patient's vital parameters in relation to his hemodynamic instability, since blood flow and dialysate flow are lower than conventional hemodialysis.

The Nephrology Quiz and Questionnaire remains an extremely popular session for attendees of the Annual Kidney Week Meeting of the American Society of Nephrology. Once again, in 2014 the conference hall was overflowing with audience members and eager quiz participants. Topics covered by the expert discussants included electrolyte and acid-base disorders, glomerular disease, ESRD/dialysis, and transplantation. Complex cases from each of these categories along with single-best-answer questions were prepared and submitted by the panel of experts. Before the meeting, program directors of United States nephrology training programs and nephrology fellows answered the questions using an Internet-based questionnaire. During the live session, members of the audience tested their knowledge and judgment on a series of case-oriented questions prepared and discussed by the experts. They compared their answers in real time using audience response devices with the answers of the nephrology fellows and training program directors. The correct and incorrect answers were then discussed after the audience responses and the results of the questionnaire were displayed. As always, the audience, lecturers, and moderators enjoyed this educational session. This article recapitulates the acid-base and electrolyte disorders portion of the session and reproduces its educational value for the readers of the Clinical Journal of the American Society of Nephrology. Enjoy the clinical cases and expert discussions.
