Effectiveness

How Dapsone Affects Patients

Dapsone is a medication that has anti-inflammatory, antibacterial, and antibiotic properties. It is used to treat leprosy, malaria, and AIDS-related Pneumocystic carinii pneumonia. After taking it orally, it is quickly absorbed and spread throughout the body. It tends to remain in the skin, muscles, liver, and kidneys for up to three weeks after the treatment has stopped.

How Dapsone works in the body

Dapsone stops bacteria from multiplying by blocking the production of an important molecule. The way it works to reduce inflammation is unclear.

When to interrupt dosage

The suggested dosage of Dapsone is determined by the diagnosed condition, such as moderate Pneumocystis pneumonia, Relapsing Polychondritis and prophylaxis of mild Pneumocystis pneumonia. The dosage fluctuates based on the administration technique (e.g. Gel - Topical or Topical) demonstrated in the table underneath.

Dapsone for Chronic Inflammatory Skin Disease Marked by Blisters

Dapsone has completely changed my life for the better. I was diagnosed with DH 24 years ago and have been taking half a 100mg tablet ever since then. It's great, but you can't take NSAIDs while on it because it'll make your symptoms 10 times worse.

Dapsone for Chronic Inflammatory Skin Disease Marked by Blisters

I unfortunately had a lot of side effects from this treatment, including stomach issues and muscle soreness. I only took three pills and felt like I was back on chemo. It's effective but not worth how sick it made me.

Patient Review

12/1/2016

Dapsone for Disease of the Mouth and Eyes Marked by Blisters

Dapsone was prescribed to me for pemphigoid. It caused a reduction in red blood cells, anemia and yellowing of skin. I was reduced from one to 50mg, which made me tired and fatigued. Now I'm forgetful and anxious. The blisters have been reduced but never gone away. I didn't expect the mental effects. Worried because I have important job and am not old.

AI-DBT for Suicide Prevention in HIV/AIDS

18+
All Sexes
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.

All Sexes
Washington D.C., United States

This project will explore the development of a personalized decision support tool to assist with pre-exposure prophylaxis (PrEP) initiation and persistence among patients identified in the emergency department (ED) and urgent care settings as PrEP eligible. First, the investigators will use a sequence of validated implementation science methodologies to develop and validate a decision support tool designed to optimize PrEP persistence by strengthening self-efficacy by addressing the multifaceted medical and social needs of the individual patient. The investigators will then test the preliminary effectiveness of this tool through a pilot stepped wedge implementation trial in two EDs and an urgent care in Baltimore, MD and Washington, DC among 120 PrEP eligible patients to determine PrEP initiation, linkage to care, persistence, and adherence rates.

Behavioral vs Mindfulness Treatments for Insomnia in HIV

50 - 99
All Sexes
Birmingham, AL

The goal of this clinical trial is to examine the effects of a telephone-delivered Brief Behavioral Treatment Insomnia (BBTI) versus a Brief Mindfulness Treatment (BMT) on cognitive and sleep outcomes in older adults with HIV. The main questions it aims to answer are: What are the effects of BBTI vs BMT on self-reported and observed sleep outcomes in older adults with HIV and insomnia up to 1-year post-intervention? What are the effects of BBTI vs BMT on self-reported and observed cognitive comes in older adults with HIV and insomnia up to 1-year post-intervention? What is the association between Alzheimer's Disease biomarkers and sleep and cognitive outcomes in older adults with HIV receiving BBTI vs BMT? Participants will: * Complete 4 weeks of telephone-delivered BBTI or BMT * Attend baseline, post-intervention, and 1-year post in-person visits for sleep and cognitive assessments * Have blood collected at all three time points

All Sexes
Birmingham, AL

The goal of this study is to examine two types of olfactory interventions (olfactory training vs overnight odor diffuser) in adults with HIV. The two research questions are: 1. Determine if participants find the intervention acceptable and assess feasibility of the study. 2. Determine if the intervention improves olfactory function and cognitive function. Participants will come to our office and be administered the baseline battery of questions including olfactory and cognitive performance tests. Then they will be randomized and sent home with one of the two interventions (below) in which they will engage in it for 8 weeks, after which they come back to our office for the posttest battery of questions including olfactory and cognitive performance test. 1. Olfactory Training at Home -- 4 scents in which they will smell twice a day for 8 weeks. 2. Overnight Diffuser Group -- a single scent diffuser that participants will turn on while they sleep and use for 8 weeks.

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.

N-803 for HIV

18 - 70
All Sexes
San Francisco, CA

Even though HIV medicine stops the virus from making more copies of itself, the virus remains in the body by hiding inside of immune cells. This hidden virus is referred to as the "latent reservoir." Researchers on this team are studying whether stimulating the immune system can change the nature of the latent reservoir and if this could help people control HIV without the need to take regular HIV medicine. This study is testing a drug called N-803. N-803 is also known as Interleukin-15 or "IL-15", a powerful and long lasting protein that can affect the immune system by stimulating immune cells such as CD8+ T cells and natural killer (NK) cells. CD8+ T cells and NK cells are both crucial for eliminating infected cells. The drug is FDA-approved for the treatment of bladder cancer, but in this study the drug is being used experimentally for HIV.
