The polymerase chain reaction (PCR) method was used to determine the presence and amount of human T lymphotropic virus type I (HTLV-I) proviral DNA in central nervous system (CNS) tissue obtained at autopsy from 6 patients with HTLV-I-associated myelopathy (HAM)/tropical spastic paraparesis (TSP), 1 patient with adult T-cell leukemia (ATL) and CNS infiltration of leukemic cells, and 9 control subjects with other neurological disorders. HTLV-I pX and env but not pol DNA were detected in CNS tissue from 5 of 6 patients with HAM/TSP. The ATL samples were positive for pX, env, and pol DNA by PCR. None of the control samples was consistently positive for HTLV-I by PCR, but all showed positive bands on beta-globin PCR. Quantitative PCR combined with histological studies showed no correlation between HTLV-I proviral DNA amounts and extent of perivascular mononuclear cell infiltration in the HAM/TSP CNS. Also, the amounts of pX and probably env DNA were greater in the HAM/TSP samples than in the ATL sample, although the extent of mononuclear cell infiltration was far less in the HAM/TSP samples than in the ATL sample. Therefore, in addition to infiltrating mononuclear cells, constituent cells of the CNS may harbor the HTLV-I genome, at least in the pX and env regions, in patients with HAM/TSP.

D015493 Paraparesis, Tropical Spastic A subacute paralytic myeloneuropathy occurring endemically in tropical areas such as the Caribbean, Colombia, India, and Africa, as well as in the southwestern region of Japan; associated with infection by HUMAN T-CELL LEUKEMIA VIRUS I. Clinical manifestations include a slowly progressive spastic weakness of the legs, increased reflexes, Babinski signs, incontinence, and loss of vibratory and position sensation. On pathologic examination inflammatory, demyelination, and necrotic lesions may be found in the spinal cord.

D016133 Polymerase Chain Reaction In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
