Memantine for the Treatment of Cognitive Impairment in Systemic Lupus Erythematosus
Lupus Erythematosus, Systemic
A phenome-wide association study (PheWAS) identified an association between a variant in the human gene for the N2A subunit of the N-methyl-D-aspartate (NMDA) receptor, GRIN2A, and Systemic Lupus Erythematosus (SLE). A single nucleotide polymorphism (SNP) in this gene encodes... expand

A phenome-wide association study (PheWAS) identified an association between a variant in the human gene for the N2A subunit of the N-methyl-D-aspartate (NMDA) receptor, GRIN2A, and Systemic Lupus Erythematosus (SLE). A single nucleotide polymorphism (SNP) in this gene encodes for increased NMDA receptor activity. Based on the potential function of the associated SNP and published literature, alterations in SNP function signaling may underlie a cluster of symptoms. The objective of this study is to evaluate the safety, tolerability and efficacy of memantine, an NMDA receptor antagonist, in a precise patient subset with SLE. Participants will complete a full 14-week clinical trial, receiving either memantine or a placebo. Participants' blood will be drawn to test for various antibodies as well as organ function. Patients' urine will also be collected to assess organ function and pregnancy for females at a number of specific time points. The overall goal is to develop a safe and inexpensive therapeutic approach to reduce debilitating cognitive symptoms in a precisely selected SLE sub-population.

The purpose of the Trial-Ready Cohort - Down Syndrome (TRC-DS) is to enroll 120 non-demented adults (ages 35-55) with Down syndrome (DS) into a trial ready cohort (TRC). Participants enrolled in the TRC-DS will undergo longitudinal cognitive and clinical assessment, genetic and biomarker testing, as well as imaging and biospecimen collection. Using these outcome measures, researchers will analyze the relationships between cognitive measures and biomarkers of Alzheimer's disease (AD) to identify endpoints for AD clinical trials in DS that best reflect disease progression. TRC-DS is collaborating with the Alzheimer's Disease Biomarker Consortium-Down Syndrome (ABC-DS) to allow study participants to be concurrently enrolled in both ABC-DS and TRC-DS, referred to as "co-enrollment". ABC-DS is a longitudinal, observational research study that is overseen at University of Pittsburgh Coordinating Center. ABC-DS participants who express interest in potentially joining a clinical trial in the future and who meet TRC-DS eligibility criteria, may choose to co-enroll in TRC-DS at an ABC-DS Site. Co-enrolled participants will adhere to the ABC-DS protocol and schedule of activities, but agree to share their data with the TRC-DS team and to receive invitations for future participation in clinical trials.

Chronic kidney disease (CKD) is a burden of morbidity and mortality. Increased protein breakdown in skeletal muscle (wasting) and ectopic fat deposition are important determinants of poor clinical outcome in patient with CKD. Insulin resistance plays a critical role in skeletal muscle wasting and ectopic fat deposition. Glucagon-like peptide-1 receptor agonists (GLP-1RA) decrease ectopic fat deposition in patients with type 2 diabetes, prediabetes, obese and overweight subjects. The influence of GLP-1RA on ectopic fat deposition in CKD patients in unknown. The investigators' will test the hypothesis that GLP-1RA decreases intermuscular (ectopic) fat deposition in patients with stage 3-4 CKD. The investigators' will do so by addressing the following specific aims: Specific Aim 1: To test the hypothesis that GLP-1RA decreases intermuscular fat deposition in patients with stage 3-4 CKD. Specific Aim 2: To test the hypothesis that GLP-1RA improves skeletal muscle mitochondrial function in patients with stage 3-4 CKD. Specific Aim 3: To test the hypothesis that GLP-1RA improves physical performance in patients with stage 3-4 CKD. Specific Aim 4: To test the safety and feasibility of 12 weeks of dulaglutide 1.5 mg/wk administration as an adjunct therapy to the standard care of patients with stage 3-4 CKD.

The primary purpose of this study is to see if people with HIV who had a significant weight gain after starting INSTI (integrase strand transfer inhibitor)+TAF/FTC (tenofovir alafenamide/emtricitabine) (TAF/3TC (lamivudine)) regimen could either slow their rate of weight gain or lose weight within about 1 year if they switch to a regimen containing doravirine (DOR; a newer, non-nucleoside reverse transcriptase inhibitor medication). The study will also try to see if participants changing from TAF/FTC (or TAF/3TC) to TDF/FTC (or TDF/3TC) will experience less additional weight gain or a reduction in overall body weight at 48 weeks compared to persons continued on an INSTI + TAF/FTC (or TAF/3TC) combination. INSTINs assessed in A5391 include bictegravir (BIC), dolutegravir (DTG), or raltegravir (RAL). Additionally, the study will see whether a change in ART can affect things like waist circumference, metabolic and cardiovascular health, fat and lean mass body composition, bone health, and maintenance of virologic suppression. Finally, the study will look at the safety and tolerability of DOR plus either TAF/FTC (or TAF/3TC) versus TDF/FTC (or TDF/3TC).

The overall purpose of this study is to test the feasibility of a web-based storytelling intervention for rural-dwelling children (ages 8-17) with serious advanced illnesses. There is a growing need for home-based end-of-life and palliative care for children with serious illnesses. While palliative care interventions offered in home settings are significantly lacking, the problems are magnified by substantial gaps in access to palliative care for rural populations. Web-based recruitment and intervention methods have the potential to access hard-to-reach rural populations and provide a cost-effective health care. In particular, legacy-making (i.e., actions/behaviors aimed at being remembered) is one strategy to help decrease suffering and improve psychosocial outcomes for children with serious illness and end of life needs. Storytelling has successfully documented child legacies and may be an ideal format for children. Guided by our existing, web-based digital storytelling intervention and previous work, this project will offer a remotely-delivered legacy-making intervention to rural-dwelling children with diverse serious, advanced health conditions and their parents.

Deficits in cognitive control are core features of late-life depression, contributing both to emotion dysregulation and problems with inhibiting irrelevant information, conflict detection, and working memory. Clinically characterized as executive dysfunction, these deficits are associated with poor response to antidepressants and higher levels of disability. Improvement of cognitive control network (CCN) dysfunction may benefit both mood and cognitive performance, however no current pharmacotherapy improves CCN deficits in LLD. Supported by pilot data, Investigators propose that nicotine acetylcholine receptor agonists enhance CCN function and resultantly improve mood and cognitive performance in late-life depression. The objective of this initial R61-phase trial is to first determine whether transdermal nicotine enhances CCN neural activity in an exposure-dependent fashion during an emotional response inhibition task (the emotional Stroop task). Investigator's approach for the R61 phase is to examine in 36 older adults with Major Depressive Disorder whether transdermal nicotine patches enhance CCN activity over 12 weeks as measured during fMRI with the emotional Stroop task while measuring nicotine and nicotine metabolite levels. Transdermal nicotine has a mechanism of action that is distinct from current antidepressants, potentially making it a potentially important antidepressant augmentation agent. If hypotheses are correct, as patches are commercially available, this approach could be rapidly moved into definitive studies and may have applicability to other psychiatric disorders characterized by CCN dysfunction.

Neurofibromatosis Type 1 (NF1) is a common genetic disorder that is associated with a four times greater risk of learning disabilities, including reading disabilities, and a deficiency of neurofibromin - a protein important in a signaling pathway that regulates learning and memory. Our previous work (NS49096) demonstrated that school-age children with NF+RD can respond to standard phonologically-based reading tutoring originally developed to treat reading disability in the general population. Combining our work with that by other researchers suggesting that a medication (Lovastatin) may counteract the effects of the deficient neurofibromin, and possibly ameliorate learning disabilities in NF1, the investigator propose to examine the synergistic effects of medication plus reading tutoring.
