- Human T-cell lymphotropic virus type 1 associated myelopathy/tropical spastic paraparesis (HAM/TSP) is an infection of the spinal cord. The infection is caused by a virus that has been known to cause cancers like leukemia and lymphoma. It causes a weakening of the legs. Researchers want to see if raltegravir, a drug for treating human immunodeficiency virus (HIV), can be used to treat HAM/TSP. They will see if the drug can reduce the amount of virus in the blood of people with HAM/TSP.
Objectives:
- To see if raltegravir can reduce the viral load of people with HAM/TSP.
Eligibility:
- Individuals at least 18 years of age who have HAM/TSP.
Design:
- Participants will be screened with a physical exam and medical history. Blood samples will be collected. Imaging studies will be performed. A lumbar puncture will also be taken.
- Participants will take the study drug twice a day for 6 months. They will note each dose in a study diary, as well as any side effects.
- At the 6-month visit, participants will stop taking the study drug. They will have a physical exam and blood samples, as well as other tests.
- Participants will have two further exams 9 months and 15 months after starting the study drug. They will have a physical exam and blood samples, as well as other tests.

INCLUSION CRITERIA: -18 years or older -Diagnosis of HAM/TSP as defined by WHO criteria, including a positive HTLV-1 EIA and confirmatory Western Blot. -Patient must be willing and able to comply with all the aspects of trial design and follow-up. -Patients must be able to provide informed consent -If able to become pregnant or to father a child, agreeing to commit to the use of a reliable/accepted method of birth control (i.e. hormonal contraception (birth control pills, injected hormones, vaginal ring), intrauterine device, barrier methods with spermicide (diaphragm with spermicide, condom with spermicide) or surgical sterilization (hysterectomy, tubal ligation, or vasectomy) for the duration of treatment arm of the study EXCLUSION CRITERIA: -Alternative diagnoses that can explain neurological disability -Clinically significant medical disorders that, in the judgment of the investigators might expose the patient to undue risk of harm confound study outcomes or prevent the patient from completing the study. Examples of such conditions include but are not limited to poorly controlled cardiopulmonary conditions such as congestive heart failure, asthma or uncontrolled hypertension. -Patient has received immunomodulatory/immunosuppressive therapy (including steroids) in the preceding 6 months. -Patient with known myopathy or risk factors for CK elevation including being on other drugs known to cause myopathy or rhabdomyolysis. -Pregnant or lactating women. -Patient has received other investigational drugs within 6 months before enrollment -Positive serological evidence of HIV, HTLV-II, Hepatitis B or C. -Abnormal screening/baseline blood tests exceeding any of the limits defined below: --Serum alanine transaminase (ALT) or aspartate transaminase (AST) levels greater than 3 times the upper limit of normal values; total bilirubin > 2.0mg/dl; Serum amylase or lipase levels greater than twice the upper limit of normal values; serum creatine phosphokinase (CK) level exceeding 3 xULN and confirmed on repeat testing in 2 weeks. --Platelet count < 75,000/mm(3) --Serum creatinine level > 2.0 mg/dl
