Treatment of Psychosis and Agitation in Alzheimer's Disease

Clinically, many patients with AD show no response or minimal response to antipsychotics for symptoms of agitation/aggression or psychosis, or they have intolerable side effects on these medications. Antipsychotics have a wide range of side effects, including the risk of increased mortality (60-70% higher rate of death on antipsychotic compared to placebo) that led to an FDA black box warning for patients with dementia; a more recent review and meta-analysis showed a 54% increased risk of mortality. In addition, some patients show only partial response to antipsychotics and symptoms persist. For these reasons, the investigators need to study alternative treatment strategies. Currently, there is no FDA-approved medication for the treatment of psychosis or agitation in AD. The investigators innovative project will examine the efficacy and side effects of low dose lithium treatment of agitation/aggression with or without psychosis in 80 patients with AD in a randomized, doubleblind, placebo-controlled, 12-week trial (essentially a Phase II trial). The results will determine the potential for a large-scale clinical trial (Phase III) to establish the utility of lithium in these patients.

Inclusion Criteria:
1. Male and female adults. 2. Diagnosis of possible or probable AD by standard NIA criteria (McKahnn et al, 1984; McKhann et all, 2011) 3. Folstein MMSE 5-26 out of 30 4. Neuropsychiatric Inventory (NPI) agitation/aggression subscale score > 4. On each subscale (frequency X severity), a score higher than 4 represents moderate to severe symptoms. 5. Female patients need to be post-menopausal 6. Availability of informant; patients without an informant will not be recruited. Patients who lack capacity must have a surrogate.
Exclusion Criteria:
1. Medical contraindication to lithium treatment or prior history of intolerability to lithium treatment. Contraindications to lithium in this study include: resting tremor causing functional impairment, history of falls in the last month, untreated thyroid disease or any abnormal thyroid function test (T3, T4, or TSH), creatinine level greater than 1.5 mg/100ml or a glomerular filtration rate less than 44ml/min/ 1.73m2; blood pressure > 150/90 mm Hg; heart rate < 50 bpm; unstable cardiac disease based on history, physical examination, and ECG. 2. Medications, in combination with lithium, known to have adverse renal effects, including therapeutic or higher doses of diuretics, i.e. hydrochlorothiazide greater than 25mg daily or furosemide greater than 10mg daily. Whenever feasible, patients receiving concomitant antidepressants or antipsychotics will be washed off these medications for at least 24 hours before starting lithium. Patients who do not wish to discontinue antipsychotics or antidepressants, typically because of family member/caregiver objection, will be allowed to enter the trial provided there is no contraindication to concomitant lithium use with that specific psychotropic medication. During the trial, patients will be permitted to receive lorazepam as needed up to 1 mg/day for anxiety/insomnia, and non-benzodiazepine hypnotics, e.g., zolpidem. 3.

Suicidal behavior or dangerous behavior with serious safety risk or risk of physical harm to self or others. 7. Parkinson's disease, Lewy body disease, multiple sclerosis, CNS infection, Huntington's disease, amyotrophic lateral sclerosis, other major neurological disorder. 8. Clinical stroke with residual neurological deficits. MRI findings of cerebrovascular disease (smallinfarcts, lacunes, periventricular disease) in the absence of clinical stroke with residual neurological deficits will not lead to exclusion. 9. Acute, severe, unstable medical illness. For cancer, patients with active illness or metastases will be excluded, but past history of successfully treated cancer will not lead to exclusion. 10. QTc interval > 460 ms at the time of baseline EKG is an exclusion criterion for treatment. 11. Hypernatremia as determined by serum sodium level > 150 meq/L.

Acute Kidney Injury Genomics and Biomarkers in TAVR Study

In the last decade, transcatheter aortic valve replacement (TAVR) has become an increasingly utilized alternative procedure for replacing a stenotic aortic valve. This study collects clinical information, DNA, blood and urine samples (throughout procedural hospitalization) in order to investigate the incidence of acute kidney injury (AKI) in patients undergoing TAVR and to identify key clinical and procedural predictors of AKI. This study seeks to identify blood and urine biomarkers that can be used for early detection of AKI around the time of the procedure. The study seeks to assess for novel genetic variants associated with development of AKI after TAVR. Finally the study seeks to assess for novel genetic variants and biomarkers that are associated with adverse cardiovascular events after TAVR and to further explore how these events may inter-relate with acute kidney injury.

Alzheimer's Disease Neuroimaging Initiative 3 (ADNI3) Protocol (ADNI3)

Since its launch in 2004, the overarching aim of the Alzheimer's Disease Neuroimaging Initiative (ADNI) has been realized in informing the design of therapeutic trials in AD. ADNI3 continues the previously funded ADNI-1, ADNI-GO, and ADNI-2 studies that have been combined public/private collaborations between academia and industry to determine the relationships between the clinical, cognitive, imaging, genetic and biochemical biomarker characteristics of the entire spectrum of Alzheimer's disease (AD). The overall goal of the study is to continue to discover, optimize, standardize, and validate clinical trial measures and biomarkers used in AD research.

Precision Event Monitoring for Patients With Heart Failure Using HeartLogic™ (PREEMPT-HF)

The goal of the PREEMPT-HF study is to collect device and clinical event data to evaluate extended applications of the HeartLogicTM Heart Failure Diagnostic (HeartLogic) in a broad spectrum of heart failure (HF) patients with an implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy defibrillator (CRT-D). There are no primary safety and/or efficacy endpoints for this study. Heart failure (HF) is a complex clinical syndrome with high morbidity, mortality, and economic burden. Chronic HF is persistent, gradually progressive, and punctuated by episodes of acute worsening leading to hospitalizations. Therefore, there remains an unmet clinical need to slow the progression of HF and prevent hospitalizations. HeartLogicTM, available in Boston Scientific cardiac resynchronization therapy devices and defibrillators (CRT-Ds and ICDs), combines novel sensor parameters such as heart sounds and respiration with other measurements like thoracic impedance, heart rate, and activity into a HeartLogic Index for the early detection of worsening HF. However, there is limited data on the association of HeartLogic with the risk of HF readmissions and tachyarrhythmias, or for phenotyping the broad spectrum of HF patients.
