Effectiveness

How Atovaquone Affects Patients

Atovaquone is a fat-soluble drug that resembles [ubiquinone]. It works by selectively affecting energy production in cells and process that create energy, such as ATP and pyrimidine biosynthesis. Atovaquone is believed to target a specific part of the cell (cytochrome bc1 complex, or complex III) in Plasmodia. Unlike other drugs, atovaquone does not have a high risk of reducing bone marrow production, making it a safe and beneficial treatment for those who have undergone bone marrow transplantation.

How Atovaquone works in the body

We don't know exactly how atovaquone works against Pneumocystis carinii, but it appears to target the cytochrome bc1 complex, which plays an important role in the electron transport chain. This action prevents important metabolic enzymes from working, which leads to the inhibition of nucleic acid and ATP synthesis. Atovaquone also has been shown to be effective against Toxoplasma gondii in laboratory tests.

When to interrupt dosage

The measure of Atovaquone is contingent upon the pinpointed condition, such as prophylaxis of Pneumocystis jiroveci pneumonia, Genus Pneumocystis and Toxoplasmosis.

Atovaquone for A type of Parasitic Infection - Babesiosis

I'm not done with the treatment yet, so I can't give it a full five stars. But I have definitely felt an improvement within two weeks! And it's easy to measure how much you're taking- just use the water displacement method. Also, make sure to eat before taking it to avoid nausea.

Newark, NJ

One in four older persons living with HIV/AIDS (PLWHA) report at least one suicide attempt in their lifetime, and the risk for death by suicide is 100 times higher in PLWHA than in the general population. Currently, there are no behavioral interventions that specifically address suicide prevention for older PLWHA, despite their unique biopsychosocial and structural risk factors. Through this work, investigators will adapt Dialectical Behavior Therapy, an evidence-based intervention for suicide prevention, for patients with PLWHA to be delivered by an AI-powered conversational Agent developed by our industry partner, Empower Health. Investigators will then pilot test the feasibility, usability, acceptability and preliminary efficacy to improve self-efficacy to manage negative emotions in n=50 older adults living with HIV/AIDS.

The HOW LONG trial is an international, multicenter, Phase IV randomized clinical trial evaluating the optimal duration of adjunctive systemic corticosteroids in immunocompromised adults with severe Pneumocystis jirovecii pneumonia (PCP) who demonstrate early clinical recovery. Participants who no longer require supplemental oxygen by day 10 of corticosteroid therapy are randomized to discontinue corticosteroids at day 10 (or hospital discharge, if earlier) versus continue corticosteroids for a total of 21 days. The trial assesses whether earlier discontinuation reduces steroid-related complications while maintaining clinical outcomes.

Decision Support Tool for HIV Treatment

18+
All Sexes
Los Angeles, CA

This study is testing software designed to help healthcare providers choose the best HIV treatment combinations for their patients. HIV medicines, known as antiretroviral therapy (ART), can be complex to manage because the right regimen depends on many factors-such as drug resistance, other health conditions, and medication schedules. Many people with HIV are cared for by general clinicians who may not have access to HIV specialists, which can make treatment decisions more challenging. In this study, healthcare providers will use patient cases to compare standard HIV treatment resources with a new clinical decision support tool that gives evidence-based ART recommendations at the point of care. The investigators hypothesize that using the tool will help providers select treatment plans that better match clinical guidelines, make decisions faster, reduce mental effort, and increase overall satisfaction with the prescribing process.

MGD020 + MGD014 for HIV

18 - 65
All Sexes
Chapel Hill, NC

This research study aims to find out how safe and well tolerated the experimental study drugs are when given to persons with HIV (PWH) taking antiretroviral therapy (ART). The study treatments are MGD014 and MGD020, which are two antibodies developed specifically for HIV, and Vorinostat, an oral medication to help expose HIV in cells to the antibodies. The study will measure the impact of study treatment on non-active HIV in cells, and how long MGD014 and MGD020 stay in the body after they are given. In this study, participants will be randomly assigned to one of three groups. All participants receive MGD014 and MGD020, given sequentially as infusions through an IV for 4 doses. Participants in one group (group A) receive only MGD014 and MGD020. Participants in another group (group B) will stop taking their ART therapy for up to 8 weeks (a temporary treatment interruption (TTI)) while receiving MGD014 and MGD020. Participants in the third group (group C) receive Vorinostat in addition to MGD014 and MGD020. Total time of participation is about 8 months and involves 13 or 18 visits, depending on group assignment.
