Seventy-four cases of systemic listeriosis occurring from 1971 to 1989 in the greater Helsinki area in Finland are reviewed with a special interest in the effect of preceding immunosuppressive therapy on the clinical presentation. Of these patients, 66% had an underlying disease, most commonly malignancy, diabetes mellitus, or renal transplantation, and 43% had received immunosuppressive therapy within 1 week before onset of listeriosis. Bacteremia and central nervous system infections (both in 43% of cases) were the most common clinical entities. The percentage of patients with meningitis was not greater among immunosuppressed patients (13/32, 41%) than among patients with underlying diseases not treated with immunosuppressive agents (9/16, 56%) or among previously healthy nonpregnant hosts (7/11, 64%). Immunosuppressed patients did not die more frequently than did those with underlying diseases not treated with immunosuppressive therapy (case fatality rate, 29% vs. 38%, respectively). However, all previously healthy non-neonatal patients survived, whereas 32% (15/47) of those with any kind of underlying disease succumbed.
