T-lymphocyte subsets in otherwise healthy patients with herpes zoster and relationships to the duration of acute herpetic pain.

T-lymphocyte subsets (CD3, CD4, and CD8 lymphocytes) in peripheral blood, parameters of cell-mediated immunity, were serially measured in 62 otherwise healthy Japanese patients with herpes zoster (HZ), and the findings were compared with those of 20 age-matched healthy controls who had had varicella but not HZ. Our objective was to elucidate whether there were changes in cell-mediated immunity, even in immunocompetent patients with HZ, and to investigate relationships between these variables and the duration of acute herpetic pain (AHP). All the patients underwent repeated sympathetic nerve blocks until pain was relieved.

Factors influencing the duration of treatment of acute herpetic pain with sympathetic nerve block: importance of severity of herpes zoster assessed by the maximum antibody titers to varicella-zoster virus in otherwise healthy patients.

Antibody responses to varicella-zoster virus (VZV) were serially investigated by the complement-fixation test in 72 Japanese of both sexes, suffering from herpes zoster (HZ), but otherwise healthy. Our objective was to elucidate whether there were mutual relationships among severities of skin lesion, maximum antibody titers to VZV, and duration of treatment for acute herpetic pain (AHP). Patients were divided into 3 groups: mild group (n = 26), moderate group (n = 26) and severe group (n = 20), according to the severity of the skin lesions.
