[Spastic paraparesis and sensory disturbance improved by prednisolone therapy].
We reported a 65-year-old man whose sister was suffering from HTLV-I-associated myelopathy (HAM) and who presented slowly progressive spastic paraparesis, sensory disturbance in the feet, tremors and cerebellar ataxia. He was also positive for serum anti-HTLV-I antibody. He first showed a head tremor at the age of 3 years. He developed a spastic and ataxic gait when aged 15 years, and it became difficult for him to walk at the age of 50 years. Examination at 65 years showed a spastic and ataxic gait and scanning speech. Hyper-reflexia and Bahinski's signs were observed. Sensation in the feet was decreased. The anti-HTLV-I antibody titer in the serum was 1:512 by the PA method, and Western blot analysis revealed bands of P19, P24, P28 and P32. Examination of the cerebrospinal fluid (CSF), including oligoclonal bands, gave normal results. The CSF was negative for anti-HTLV-I antibody. CT and MRI of the head showed cerebellar atrophy. His sister was 60 years old. She had developed a spastic gait at the age of 15 years. Sensory defects and bladder dysfunction developed when aged 35 years. Hyper-reflexia, Babinski's sign and foot clonus were observed. Sensation in the feet was decreased. The urinary residual volume was increased. Ataxia was not observed. The anti-HTLV-I antibody titer in the serum was 1:8,192 by the PA method, and Western blot analysis revealed bands of p24, p28 and p32. Examination of the CSF, including oligoclonal bands, gave only normal results.(ABSTRACT TRUNCATED AT 250 WORDS)
