NCT ID: NCT01472263 Completed - Physical Disability Clinical Trials

Use of Pentoxifylline in Human T-lymphotropic Virus Type-1 (HTLV-1) Diseases

Pentox
Start date: September 2009
Phase: Phase 3
Study type: Interventional

In this study the investigators are going to evaluate the efficacy pentoxifyline in HTLV-1 patients with neurological diseases: HAM/TSP or neurogenic bladder. In some laboratory experiments the investigators observed that this drug had the capacity to reduce the immune response in HTLV-1 infected cells. Since the exacerbated immune response is know to cause neurological disease in patients with HTLV-1 the investigators hope that pentoxifyline can alleviate symptoms and delay the progress of HAM/TSP in patients.

NCT ID: NCT01367327 Completed - Cerebral Palsy Clinical Trials

Effects of Therapeutic Music Combined With Loaded Sit-to-Stand Resistance Exercise for Children With Spastic Diplegia

Start date: January 2009
Phase: N/A
Study type: Interventional

The purpose of study is to investigate the effects of PSE Music with a "home-based" loaded STS exercise program on the functional strength, gross motor function, daily participation, exercise involvement, motor control, and gait speed for children with spastic diplegia.

NCT ID: NCT01343355 Active, not recruiting - Clinical trials for HTLV-I-Associated Myelopathy

Efficacy and Safety of Tamibarotene(AM80H) for HTLV-1 Associated Myelopathy/ Tropical Spastic Paraparesis (HAM/TSP)

Start date: January 2011
Phase: Phase 2/Phase 3
Study type: Interventional

An open-label, non-randomised, uncontrolled, proof-of-concept study of patients with HTLV-I-associated myelopathy/Tropical Spastic Paraparesis (HAM/TSP). Participants will receive oral administration of tamibarotene in the amount of 2 mg daily over a period of 12 weeks, then 4mg daily for another 12 weeks. The patients will be followed up for further 8 weeks. Efficacy will be monitored by measuring clinical scores including motor and urination function, HTLV-1 proviral load, immunological parameters, and markers in the spinal fluid. Safety will be evaluated at the same time.

NCT ID: NCT00677768 Completed - Clinical trials for Amyotrophic Lateral Sclerosis

Validation of Biomarkers in Amyotrophic Lateral Sclerosis (ALS)

BIO_ALS-01
Start date: April 2008
Phase: N/A
Study type: Observational

The purpose of this study is to collect 650 blood and 300 cerebrospinal fluid (CSF) samples from people with amyotrophic lateral sclerosis (ALS), pure lower or upper motor neuron diseases, as well as other neurodegenerative diseases and from people with no neurological disorder. Through comparison of these samples, the researchers hope to learn more about the underlying cause of ALS, as well as find unique biological markers, which could be used to diagnose ALS and monitor disease progression. Additionally, up to 600 blood samples will be collected for a sub-study for DNA analysis. Studying components of the blood, such as DNA, may help us understand what happens when genes function abnormally and how it might be related to disease.

NCT ID: NCT00340821 Completed - HTLV-I Clinical Trials

A Study of Familial and Genetic Aspects of Adult T-Cell: Leukemia/Lymphoma , Tropical Spastic Paraparesis, and Infective Dermatitis

Start date: May 17, 1993
Phase: N/A
Study type: Observational

Doctors of the University of West Indies, the Caribbean Epidemiology Center (CAREC) and the National Cancer Institute have been studying the epidemiology of HTLV-I and its role in the etiology and pathogenesis of adult T-cell leukemia/lymphoma (ALT), and aggressive T-cell lymphoma. The purpose of the current study is to evaluate familial and genetic aspects of ATL and its relationship to two other HTLV-I related conditions, HTLV-I associated myelopathy also known as tropical spastic paraparesis (HAM/TSP), and infective dermatitis. Enrollment of infective dermatitis cases was recently added and the disease entity is thought to be a harbinger for later development of either ATL or HAM/TSP. The purpose of this study is to interview patients with these conditions and perform laboratory studies (specifically, HLA and other viral or genetic studies) to better understand these diseases and their relationship to the HTLV-1 virus and the family history and genetic factors that may be involved as well.

NCT ID: NCT00076843 Completed - HTLV-1 Clinical Trials

Hu Mik-Beta-1 to Treat HTLV-1-Associated Myelopathy/Tropical Spastic Paraparesis

Start date: February 3, 2004
Phase: Phase 1
Study type: Interventional

This study will examine the use of the humanized Mik-Beta-1 (Hu Mik-(SqrRoot) 1) monoclonal antibody in patients with HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Some patients infected with the human T-lymphotropic virus type 1 (HTLV-1) virus develop HAM/TSP, a disease in which the immune response to HTLV-1 becomes directed against the person's own body in what is called an autoimmune response. Hu-Mik-Beta-1 is a genetically engineered antibody that blocks the action of a chemical produced by the body during infection or inflammation called interleukin 15 (IL-15). Blocking IL-15 may prevent the autoimmune response that results in HAM/TSP. Patients 18 years of age and older with HAM/TSP may be eligible for this study. Candidates are screened with a medical history and physical examination, blood and urine tests, and an electrocardiogram. Participants undergo the following procedures: 1. Baseline visit(s): Repeat physical examination and blood and urine tests, as well as the following: - Lumbar puncture: A local anesthetic is injected to numb the skin of the lower back. A needle is inserted in the space between the bones where the cerebrospinal fluid that bathes the brain and spinal cord circulates below the spinal cord. About 4 tablespoons of fluid is collected through the needle. - Magnetic resonance imaging (MRI): This test uses radio waves and magnets to produce images of body tissues and organs. The patient lies on a table that slides into a metal cylinder surrounded by a strong magnetic field. During part of the scan, a contrast agent is injected to brighten the images. - Apheresis: This procedure is used to collect large quantities of white blood cells. Whole blood is collected through a needle in an arm vein and directed into a machine that separates it into its components by spinning. The white cells and plasma are removed and the rest of the blood (red cells and platelets) is returned to the body through the same needle. 2. Hu Mik-Beta-1 treatment: Infusions of Hu Mik-Beta-1 are given through a vein every 3 weeks for nine doses. The first treatment requires at least an overnight hospital stay; subsequent infusions are given in the outpatient clinic. 3. Blood and urine tests and a physical examination at every treatment visit and a skin test at one treatment visit. 4. Research tests at the end of the 24-week treatment period, including lumbar puncture (spinal tap), MRI scan, and apheresis. 5. After completing treatment, patients have three follow-up clinic visits for blood and urine tests, and a skin test at one follow-up visit.

NCT ID: NCT00034723 Completed - Clinical trials for Tropical Spastic Paraparesis

MRI Brain Studies in Patients With HTLV-1 Associated Myelopathy/Tropical Spastic Paraparesis

Start date: April 2002
Phase: N/A
Study type: Observational

This study will use three different magnetic resonance imaging (MRI) techniques to study HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/STP)-a disease of slowly progressive weakness in the legs. It is not known how the HTLV-1 virus causes this disease, but it is thought that as the body's immune system tries to destroy the virus, parts of the nervous system-primarily the spinal cord-are damaged. Patients 18 years of age and older with HAM/TSP and healthy normal volunteers may be eligible for this study. Participants will undergo diffusion tensor MRI, MR-spectroscopy, and magnetization transfer imaging to look at different compositional, architectural, and microscopic properties of the brain. All of these techniques are similar to conventional MRI, and like the conventional method they use a strong magnetic field and radio waves to measure structural and chemical changes in brain tissue. Each of the three scans will be done on separate days, each lasting about 1 hour. For the procedures, the patient or volunteer lies on a stretcher in a narrow metal cylinder (the scanner) and is asked to remain still for 15 to 30 minutes at a time. A special lightweight coil may be placed on the head to enhance the brain images. The subject can communicate with the person doing the scan at all times.

NCT ID: NCT00001785 Completed - Clinical trials for Tropical Spastic Paraparesis

Recombinant Human Interferon Beta-1a (Avonex) for the Treatment of Patients With HTLV-1-Associated Myelopathy (HAM)

Start date: September 1998
Phase: Phase 2
Study type: Interventional

HTLV stands for human T cell leukemia virus. HTLV-1 is a virus that attacks specific kinds of white blood cells called T cells. T cells are part of the natural defense system of the body. HTLV-1 has been associated with leukemia and lymphoma. In addition, approximately 1% of all patients infected with HTLV-1 develops a condition known as HTLV-1 associated myelopathy (HAM) / tropical spastic paraparesis (TSP). Currently there is no clearly defined, effective treatment for patients with HAM/TSP. Steroids have been used as therapy but have only been able to provide temporary relief of symptoms. Human interferon is a small protein released from different kinds of cells in the body. Interferon has been known to have antiviral and immunological effects and has been used to treat hepatitis and multiple sclerosis. Interferon Beta is released from cells called fibroblasts. These cells play a role in the production of connective tissue. The purpose of this study is to evaluate the possible role of recombinant interferon beta (Avonex) in treatment of HAM/TSP. The study is broken into three phases, a pre-treatment phase, a treatment phase, and a post-treatment phase. The total duration of the study will be 44 weeks. Patients participating in this study will receive injections of Avonex 1 to 2 times a week. Throughout the study patients will regularly submit blood samples and undergo diagnostic tests such as MRI and measures of somatosensory evoked potentials.

NCT ID: NCT00001778 Recruiting - Clinical trials for Tropical Spastic Paraparesis

Evaluation of Patients With HAM/TSP

Start date: April 6, 1998
Phase:
Study type: Observational

Objective: Human T-lymphotropic virus type-I-associated myelopathy / tropical spastic paraparesis (HAM/TSP) is a rare neurologic disorder that affects less than 5% of patients infected with the HTLV-I virus. The purpose of this protocol is to study the natural history of HAM/TSP by monitoring clinical progression of patients longitudinally. Additionally, we will attempt to define the virological and immunological changes of HAM/TSP. Study Population: Patients with HAM/TSP who fulfill World Health Organization diagnostic criteria are eligible to participate in this protocol. Asymptomatic seropositive individuals and individuals with indeterminate HTLV-1 serology are also eligible to participate. Design and Outcome Measures: A longitudinal assessment of clinical, virological and immunological progression in HAM/TSP will be accomplished through periodic testing and evaluation. Asymptomatic seropositive individuals, those with seroindeterminate HTLV-I serology and normal volunteers may serve as controls. Longitudinal standardized neurological examinations will be performed. Longitudinal samples of serum, plasma, and lymphocytes may be obtained from participants. Lumbar punctures may be performed on all participants. These samples will be used virological and immunological assays. A focus is on the relationships between the characteristics of viral infection, the immune response, and the genetic makeup.

NCT ID: NCT00001156 Completed - Multiple Sclerosis Clinical Trials

Assessment of Patients With Multiple Sclerosis (MS)

Start date: January 23, 1976
Phase: N/A
Study type: Observational

Multiple sclerosis (MS) is a disease of the nervous system. The exact cause of MS is unknown, but it is believed to be an autoimmune condition. Autoimmune conditions are diseases that cause the body's immune system and natural defenses to attack healthy cells. In the case of MS, the immune system begins attacking myelin, the cells that make up the sheath covering nerves. Without myelin, nerves are unable to transmit signals effectively and symptoms occur. This study is directed toward a better understanding of the cause of Multiple Sclerosis (MS). Researchers will evaluate patients with a tentative diagnosis of MS or other neurological diseases possibly caused by a immunological reaction. Patients will undergo a series of three MRIs, taken once a month for three months and submit blood samples for immunological studies.
