33 Clinical Trials for Various Conditions
The purpose of this study is to evaluate the efficacy of pregabalin compared to placebo in reducing neuropathic pain associated with HIV neuropathy.
Neuropathy results from damage to the nerves in the feet and legs. It is usually experienced as pain, tingling or numbness. In HIV-infected people, neuropathy can result from the infection itself or be a side effect of antiretroviral treatment. The purpose of this study is to determine whether two different drugs, methadone and duloxetine, reduce neuropathy-associated pain in HIV-infected people. This study will also examine whether utilization of both of these drugs is more effective than treatment with only one.
To evaluate the safety and efficacy of pregabalin in reducing neuropathic pain associated with HIV neuropathy
The purpose of this study is to determine if medicinal cannabis (marijuana) is safe and effective for treating pain in individuals with HIV-associated distal, sensory-predominant polyneuropathy (DSPN).
Study to determine if pregabalin is more effective than placebo in treating subjects with nerve pain associated with HIV neuropathy.
HIV is associated with painful peripheral neuropathy. Disability is often significant. Alpha-Lipoic Acid's antioxidant properties may have benefit in this condition.
Distal sensory peripheral neuropathy (DSP) is a chronic, debilitating painful condition affecting quality of life in persons living with HIV. Treatments prescribed to manage DSP pain, such as nonnarcotic and narcotic analgesics, antidepressants and anticonvulsants, are largely ineffective. In HIV there are no FDA-approved drugs for this indication. This study assesses in a randomized controlled clinical trial, the efficacy of novel non-pharmacologic pain management approaches to reduce HIV-related DSP pain and improve quality of life.
Acute cannabis administration is reported to alleviate HIV neuropathic pain (HIV-NP), but there is limited knowledge about the effects of cannabis constituents (delta-9 tetrahydrocannabinol/THC and cannabidiol/CBD), the consequences of long-term cannabis use, and the impact of cannabis on endocannabinoid (EC) function in people living with HIV- NP. Our objective is to address these three fundamental gaps in our knowledge by: 1) examining the acute effects of various CBD/THC products on HIV-NP, 2) utilizing a mHealth text messaging protocol, Individual Monitoring of Pain and Cannabis Taken (IMPACT) to monitor daily real-world cannabis use and changes in pain; and 3) studying the relationship between cannabinoids, EC biomarkers, and chronic neuropathic pain
A clinical outcomes study measuring reduction in pain and numbness experienced in four types of peripheral neuropathy patients during 60 day administration of the an amino acid formulation.
Patients with postherpetic neuralgia (PHN), diabetic neuropathy (DN), complex regional pain syndrome (CRPS), carpal tunnel syndrome, HIV neuropathy, idiopathic sensory neuropathy, or other peripheral neuropathy participated in a Phase IV clinical trial to assess the comparative efficacy and safety of Lidoderm monotherapy versus gabapentin monotherapy in treating a diverse group of peripheral neuropathic pain patients.
The purpose of the study is to gain initial information on the tolerability and feasibility of high-concentration capsaicin patches for the treatment of painful HIV-associated neuropathy, whether resulting from HIV disease and/or antiretroviral drug exposure. The study will also provide preliminary safety and efficacy information.
This study is to explore the effects of transcutaneous nerve stimulation (TENS) and mindfulness meditation in persons living with HIV (PLHIV) and painful neuropathy in the feet.
The purpose of this study is to evaluate the effectiveness of methadone alone and in combination with SAB378 for the treatment of painful HIV-associated neuropathy.
The purpose of the study is to determine if an investigational drug, NGX-4010 (high-concentration capsaicin patch), is safe, tolerable and effective in treating painful HIV-associated neuropathy.
The purpose of the study is to determine if an investigational drug, NGX-4010 (high-concentration capsaicin patch), is effective in treating painful HIV-associated neuropathy.
WHAT IS THE PURPOSE OF THIS STUDY? The investigators want to know if wearing a pair of splints at night works to bring the pain down and help you sleep better (in people living with HIV/AIDS related neuropathy). HOW MANY PEOPLE WILL PARTICIPATE? About 58 to 88 people will take part in this study at the Harris County Hospital District (HCHD). WHAT WILL HAPPEN DURING THIS STUDY? As a participant, you will be assigned to one of two treatment groups. In one group, you will be asked to wear leg splints at night and the other you will wear the liners of the splints only. You will be asked to answer questions about how well you sleep, how long you sleep, and about your discomfort at the legs. The researcher will be there to help, but the investigators want you to answer the questions on your own if you can. You will be asked to reach forwards standing next to a wall and to walk for 6 minutes after that. The tests will de done in random order. The sessions will be done at the beginning, at week three and week six. You should finish all of the testing and questionnaires in an hour or less, for a total of three hours over six weeks in the investigators clinic. You will receive instructions on how to use the splints with liners or the liners alone at home. You will be asked to wear them at night only for the next 6 weeks. Finally, the principal investigator will contact you weekly by phone, to discuss issues of comfort and your ability to adhere to the instructions provided.
This is a sample-size-limited, randomized, blinded (subject and evaluator), sham acupuncture/placebo moxibustion (sham acu/placebo moxa) controlled clinical trial. The subjects in this study will be 50 men and women with HIV infection who have a diagnosis of distal symmetric peripheral neuropathy (DSP). Subjects will be randomized to one of two experimental intervention conditions: * Condition 1: subjects receive acu/moxa treatment; and * Condition 2 (Control Group): subjects receive sham acu/placebo moxa. All subjects in Conditions 1 and 2 will attend 16 scheduled sessions over 15 weeks, be administered the same instruments, and submit their daily symptom diaries for analysis. There will be six weeks of twice weekly treatment sessions, and three follow-up sessions at weeks 9, 11, and 15. All conditions will be identical in duration and be administered by licensed acupuncturists trained in traditional Chinese medicine (TCM).
To evaluate whether smoked marijuana reduces pain in people with HIV-related peripheral neuropathy.
To compare the effects of intranasal peptide T and placebo in the treatment of painful peripheral neuropathy associated with human immunodeficiency virus (HIV) infection.
To assess the efficacy, safety, and tolerability of recombinant human nerve growth factor ( rhNGF ) in the treatment of HIV-associated sensory neuropathy. AS PER AMENDMENT 5/6/97: To compare the change in viral load between the double-blind phase baseline and week 4 in placebo and active rhNGF recipients. To ensure that rhNGF does not induce an increase in viral load compared with viral load changes seen with placebo. Up to now, treatments for HIV-associated sensory neuropathy have been symptomatic, relying on pain-modifying agents or membrane-stabilizing drugs. Because nerve growth factor is important in the development and maintenance of sympathetic and sensory neurons and their outgrowths, it is proposed that recombinant human nerve growth factor may provide a specific restorative treatment for HIV-associated painful sensory neuropathy.
To evaluate the separate and combined efficacy of a standardized acupuncture regimen and amitriptyline on the relief of pain due to peripheral neuropathy and on the quality of life of HIV-infected patients. Both amitriptyline, an antidepressant, and acupuncture, a Chinese medical approach that uses needles to relieve pain, have been used successfully to reduce pain in some people. It is not known how effectively these approaches relieve or reduce pain in patients with peripheral neuropathy secondary to HIV infection.
To assess the efficacy, safety, and tolerability of amitriptyline hydrochloride versus mexiletine hydrochloride in reducing pain intensity in patients with HIV-related painful peripheral neuropathy. No large-scale controlled clinical trials of symptomatic therapy for painful HIV-related neuropathy have been attempted. Both amitriptyline and mexiletine have been useful in the management of painful neuropathies; however, both are associated with certain toxicities. In this comparative study of amitriptyline and mexiletine, benztropine mesylate also will be included as an active placebo to mimic the side effects of the study drugs.
The purpose of this study is to evaluate how safe and how well a treatment works compared to placebo for people with nerve pain that begins in their feet and moves up the leg to just below the knee. Participation may last up to 30 weeks including screening.
The study team's prior research has shown that dysfunction of a specific nerve, called the vagus nerve, is associated with small intestinal bacterial overgrowth (SIBO), and that SIBO is associated with signs of inflammation in the blood of people living with HIV (PLWH). This research will explore pathways linking vagal dysfunction to inflammation in HIV, focusing on the gastrointestinal tract, and study whether a medication called pyridostigmine and stimulation of the vagus nerve are beneficial therapies.
This preliminary study will investigate the use of Acupuncture and Moxibustion (Acu/Moxa) for distal symmetric peripheral neuropathy (DSP) associated with HIV applying traditional Chinese medicine (TCM) evaluations conducted by a diagnostic acupuncturist. The investigators will evaluate the role of Acu/Moxa in reducing the symptoms of DSP related to HIV/AIDS and treatment side effects. The effects of symptom reduction on quality of life will also be examined. This application will establish a proof of principle for the role of Acu/Moxa in the treatment of DSP and provide data that will serve as a foundation for establishing a future larger clinical trial.
Background: Peripheral neuropathy (PN) occurs in half of the people with human immunodeficiency virus (PHIV). Currently, there is no Food and Drug Administration-approved treatment for HIV-related PN. Only half of PHIV who take medications report a significant reduction in pain. Therapeutic Chinese Massage, structured palpations or movements of soft tissues of the body, is a promising non-harmful, and non-costly intervention that can potentially alleviate or even treat PN but relevant research is limited. Method: Investigators conducted a single centered, two-arm, single-blinded randomized controlled trial pilot study to examine if a series of three weekly 25-minute therapeutic Chinese massage sessions by a therapist of therapeutic Chinese massage, compared with placebo massage, could reduce PN-related pain and improve lower extremity functioning in PHIV. Twenty PHIV were recruited from the AIDS Foundation Houston, Inc in Texas. Pain, lower extremity functioning, and health-related quality of life were assessed for both groups prior to and post-massage.
The purpose of this study is to explore a possible link between the autonomic nervous system and immune function in patients with HIV. Sometimes HIV can cause these nerves to function abnormally, this is called HIV-associated autonomic neuropathy (HIV-AN). HIV-AN is a condition that is different from person to person. In some people it causes no symptoms and is not harmful, in others it may cause symptoms such as dizziness or lightheadedness, nausea, vomiting, diarrhea, constipation, or problems urinating. Most people with HIV-AN don't know that they have it. One of the important nerves in the autonomic nervous system is the vagus nerve. Abnormal function of the vagus nerve may cause stomach and intestinal slowing, which could lead to an overgrowth of bacteria. The body senses these bacteria and tries to fight them, leading to inflammation. In this study the researchers will test whether abnormal function of the vagus nerve in HIV is associated with stomach slowing and overgrowth of bacteria, and if a drug called pyridostigmine can help.
This is a two-part study of the safety, tolerability, and efficacy of topically administered WST-057 for 16 weeks in subjects with HIV with sensory polyneuropathy.
Cross-sectional study is to explore the impact of painful neuropathy in the feet on function in persons living with HIV (PLHIV).
There are about 42 million people in the world afflicted with HIV or AIDS with about 1 million patients in the US. The epidemiology of orofacial pain has been reported extensively in the literature, yet the prevalence severity and level of pain affecting the head, face, neck and intraoral structures has not been explored in a population of HIV infected individuals. Pain, in general terms, is a common experience in HIV infected patients, even in the absence of cancer or opportunistic infections. There is a variation in the prevalence of pain in these individuals depending on the stage of disease, care setting, and study methods. The purpose of this study is: 1. To investigate the prevalence of orofacial pain in HIV infected patients during routine dental clinical assessment. 2. To study the sensory phenotype of HIV+ patients and healthy volunteers using Quantitative Sensory Testing: * To detect the presence of sensory aberrations in the orofacial complex; * To identify which nerve types are involved; * To identify the type of orofacial pain based on both sensory testing and clinical findings. 3. To determine psychological condition and nutrition status in patients with HIV. 4. To find associations between inherited traits and development of neuropathic pain.
