HAM

Brief summary

HTLV-1 Associated Myelopathy is a chronic disease of the spinal cord, caused by a virus called human T lymphotropic virus type 1(HTLV-1). Natural Killer cells provide rapid responses to viral-infected cells, acting at around 3 days after infection, and respond to tumor formation. In this trial, the investigators aim to study the therapeutic safety and the effect on HTLV-1 virus. This in turn will improve the knowledge and understanding of the disease and should lead to better therapy.

Detailed description

HAM is a chronic disease of the spinal cord, caused by a virus called HTLV-I. Natural Killer cells provide rapid responses to viral-infected cells, acting at around 3 days after infection, and respond to tumor formation. In this trial, the investigators aim to study the therapeutic safety and the effect on HTLV-1 virus. This in turn will improve the knowledge and understanding of the disease and should lead to better therapy. In a single-center, one year open-label trial, 5 HAM patients will be treated with single intravenous injection of NK cells (0.9\ 1\*10\^9). Then, the the clinical effect was evaluated by dynamic analysis of Osame's Motor Disability Score and other related physiological indices, such as HTLV-1 antibody titer in blood and cerebrospinal fluid.
