[Microbiologic study of bacteremia and fungemia in chronic hemodialysis patients].
Microbiologic study of bacteremia and fungemia in chronic hemodialysis patients. Bloodstream infections are the second cause of death in patients in chronic hemodialysis (CHD), and the knowledge of the epidemiology is useful to establish proper empiric therapies. The aim of this study was to evaluate the frequency and distribution of microorganisms, in bacteremia and fungemia in 530 patients in CHD. Two hundred and forty eight blood culture series from 114 patients with suspected bacteremia were processed; 44% of them were positive from which 71% (n=78) were clinically significative and belonged to 58 patients. Sixty eight percent of these isolates were gram-positive cocci (n:53), and 22% gram-negative rods (n:17). Staphylococcus aureus was the most prevalent pathogen showing 23% of methicillin-resistance. Candida spp. was the fourth pathogen most common in frequency.
