description Introduction: Presently, bacteremia is the principal cause of morbidity in patients undergoing hemodialysis. Gram-negative bacteria account for approximately 50 percent of documented infections. Endotoxins released during lysis of gram negative bacteremia result in inflammatory and defense response by the body and if not treated promptly result in septic shock and ultimately death of the patient. This study describes the detection of endotoxins in blood of patients with bacteremia due to gram - negative bacteria by LAL test. Method: Blood samples of 278 hemodialysis patients were analyzed in this study and pathogens were isolated from blood culture samples. Then, their antibiotic sensitivity was determined. In patients with positive blood culture, endotoxin levels were measured by LAL-test. Results: Frequency of bacteremia in patients was 13.6% . The prevalence of gram – negative bacteremia was 44.7%. E coli were the major pathogens, while staphylococcus aureus was the most common gram positive bacterium. Endotoxin was detected in 15 patients (3.8 ± 1.08 EU/ml ) . The sensitivity and specificity of endotoxins for gram – negative bacteremia were 88% and 95%, respectively. Conclusion: The results indicate that the LAL method is a fast, sensitive and simple method. There was no significant difference between the results of blood culture and LAL – test ( P > 0.05 ) .
