Bacterial agents isolated from cerebrospinal fluid of patients with Acquired Immunodeficiency Syndrome (AIDS) and neurological complications

Agentes bacterianos isolados de líquido cefalorraquidiano de pacientes com Síndrome de Imunodeficiência Adquirida (SIDA) e complicações neurológicas

Abstracts

Cerebrospinal fluid (CSF) samples from 2083 patients with acquired immunodeficiency syndrome (AIDS) and neurological complications were bacteriologically examined during a period of 7 years (1984-1990). The percentage of patients who had at least one bacterial agent cultured from the CSF was 6.2%. Mycobacterium tuberculosis was the most frequently isolated agent (4.3%), followed by Mycobacterium avium complex or MAC (0.7%), Pseudomonas spp (0.5%), Enterobacter spp (0.4%), and Staphylococcus aureus (0.3%). Among 130 culture positive patients, 89 (68.5%) had M. tuberculosis and 15 (11.6%) had MAC. The frequency of bacterial isolations increased from 1988 (5.2%) to 1990 (7.2%), partly due to the increase in MAC isolations. Bacterial agents were more frequently isolated from patients in the age group 21-30 years and from women (p<0.05).

A porcentagem de pacientes que tiveram pelo menos um agente bacteriano cultivado do LCR foi de 6,2%. Mycobacterium tuberculosis foi o mais frequentemente isolado (4,3%), seguido do complexo Mycobacterium avium ou MAC (0,7%), de Pseudomonas spp (0,5%), Enterobacter spp (0,4%), e Staphylococcus aureus (0,3%). Entre 130 pacientes com cultura positiva, de 89 (68,5%) foi isolado M. tuberculosis e de 15 (11,6%) MAC. A frequência de isolamentos bacterianos aumentou de 1988 (5,2%) a 1990 (7,2%), particularmente devido ao maior isolamento de MAC. Os agentes bacterianos foram mais frequentemente isolados de pacientes na faixa etária de 21-30 anos e de mulheres (p<0.05).
