[Hepatitis B virus antibody positive spastic paraparesis].
We present here thirteen patients (5 men and 8 women, aged 31 to 73, mean 55 years) with spastic paraparesis who showed clinical features similar to those of HTLV-1 associated myelopathy without HTLV-1 antibody, but with positive antibody to hepatitis B virus (HBV). All of these patients showed slowly progressive difficulty in walking. Five patients had previous histories of blood transfusion, of these one with history of B hepatitis. Neurologically, muscle weakness, spasticity and exaggerated deep tendon reflexes in the lower extremities were common to all the patients. Seven patients showed Babinski's reflex. Disturbance of micturition was noted in 3 patients. None showed organic changes of the spine on magnetic resonance image (MRI). None was serologically positive for syphilis and had cryoglobulin and hypergammaglobulinemia. Elevated levels of the liver enzymes were noted in two patients. All patients were positive for hepatitis B surface antibody (HBs-Ab) (EIA) but negative for hepatitis B surface antigen (HBs-Ag) (EIA). Five patients were seropositive for hepatitis C virus (HCV) (PHA). In 3 of them, reverse transcriptase polymerase chain reaction was performed but failed to detect HCV-RNA. All patients underwent spinal tap, and showed normal cell count and protein concentration in their cerebrospinal fluid (CSF). Atypical cells were not observed in all the patients. The CSFs from three patients were tested for HBs-Ag and HBs-Ab. HBs-Ag was negative in all three patients, but HBs-Ab was positive in two patients.(ABSTRACT TRUNCATED AT 250 WORDS)
