OBJECTIVE HTLV-1 proviral loads (PVLs) and some genetic factors are reported to be associated with the development of HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). However, there are very few reports on HAM/TSP having family history. We aimed to define the clinical features and laboratory indications associated with HAM/TSP having(More)
OBJECTIVE To identify the clinical features of Japanese patients with suspected hereditary sensory and autonomic neuropathy (HSAN) on the basis of genetic diagnoses. METHODS On the basis of clinical, in vivo electrophysiologic, and pathologic findings, 9 Japanese patients with sensory and autonomic nervous dysfunctions were selected. Eleven known HSAN(More)
OBJECTIVE The objective of this study was to identify new causes of Charcot-Marie-Tooth (CMT) disease in patients with autosomal-recessive (AR) CMT. METHODS To efficiently identify novel causative genes for AR-CMT, we analyzed 303 unrelated Japanese patients with CMT using whole-exome sequencing and extracted recessive variants/genes shared among multiple(More)
Recently, a study by Morgan et al. identified that the white matter lesions are detectable with MRI study in HTLV-1 carriers at the same frequency as HAM/TSP patients. Little is known about the nature of the brain lesion and its relation to the spinal cord lesion. We assessed the inflam-matory change including HTLV-1-specific cytotoxic T lymphocytes in the(More)
Some genetic factors are associated with the development of HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). So far, there is a very few report about familial HAM/TSP. This study aimed to clarify the clinical features of familial HAM/TSP. We reviewed all patients with HAM/TSP, 784 in number, hospitalized to Kagoshima University Hospital(More)
OBJECTIVE HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) can progress slowly or rapidly even though a set of symptoms such as spastic paraparesis with pathological reflexes and sweating loss of the lower extremities are commonly observed in patients. Although most of the patients are thought to be infected to HTLV-1 from their mothers(More)
There is an error in the last sentence of the Results subsection of the Abstract. The correct sentence should read: HTLV-1 PVLs were lower in cases with rapid disease progression than in those with slow progression in sporadic cases. A sentence is missing in the subsection " Clinical and laboratory findings in patients with rapid disease progression " of(More)
BACKGROUND The clinical features of myositis related with Human T-cell leukemia virus type 1 (HTLV-1) remains unclear despite epidemiological studies suggesting inflammatory myopathy associated with the virus. CASE PRESENTATION Here, we described the clinical presentations, muscle biopsy studies and laboratory results of two siblings with(More)
OBJECTIVE To determine the causative pathogen and investigate the effective treatment of a new type of encephalomyelitis with an unknown pathogen in Japan and report the preliminary ultrastructural and genomic characterization of the causative agent. METHODS From 2005 to 2012, we treated 4 Japanese patients with geographic clustering and comparable(More)
Analysis of the association between the sex and disease courses of 132 consequent patients with HTLV-1-associated myelopathy/Tropic spastic paraparesis (HAM/TSP) Objective HTLV-1-associated myelopathy/tropical spastic parapar-esis (HAM/TSP) is predominant in female. The course of disease differs by the individuals. The difference in the host's immune(More)
