Description
Summary:Several reports have related Legionella pneumophila with pneumonia in renal transplant patients, however this association has not been systematically documented in Brazil. Therefore this paper reports the incidence, by serologycal assays, of Legionella pneumophila serogroup 1 in these patients during a five year period. For this purpose sera from blood samples of 70 hospitalized patients with pneumonia from the Renal Transplant Unit of Hospital das Clinicas, FMUSP collected at the acute and convalescent phase of infection were submitted to indirect immunofluorescence assay (IFA) to demonstrate anti-Legionella pneumophila serogroup 1 antibodies. Of these 70 patients studied during the period of 1988 to 1993,18 (25.71 %) had significant rises in specific antibody titers for Legionella pneumophila serogroup 1. Incidence was interrupted following Hospital water decontamination procedures, with recurrence of infections after treatment interruption. In this study, the high susceptibility (25.71%) of immunodepressed renal transplant patients to Legionella pneumophila serogroup 1 nosocomial infections is documented. The importance of the implementation and maintenance of water decontamination measures for prophylaxis of the infection is also clearly evident. Embora vários trabalhos tem mostrado a presença de Legionella pneumophila associado a pneumopatias infecciosas em transplantados renais, tal associação não fora antes realizado de maneira sistemática no Brasil. Os autores julgaram oportuno a determinação da incidência por comprovação sorológica da Legionella pneumophila sorogrupo 1 em transplantados renais num período de 5 anos. Para tanto amostras de soros de 70 pacientes com pneumopatia infecciosa internados na UTR do HC-FMUSP, colhidos na fase aguda e convalescente da infecção, foram submetidas à reação de imunofluo-rescência indireta para pesquisa de anticorpos anti-Legionella pneumophila sorogrupo 1. Dos 70 pacientes transplantados renais com pneumopatia infecciosa estudados no período de 1988 a 1993, 18 ...
