[Determination of endotoxemia by means of the Limulus test in patients with septicemia (author's transl)]. 1979

A García Curiel, and A Cantos de la Casa, and A Martín Martín, and C Alemán Alemán

The Limulus test was applied to determine bacterial endotoxemia in 42 patients suspected of having septicemia. Hemocultures were practiced simultaneously. A comparative study is made of the two presently most commonly recommended tests for neutralizing the factors inhibiting the endotoxin-amebocyte reaction. According to our results the dilution of plasma in isotonic saline solution is preferable; we obtained a sensitivity of determination of 0.0001 micrograms of E. coli endotoxin per ml of plasm. Seventeen cases of bacteriemia were diagnosed, only one of which with sepsis due to Serratia marcescens responded positively to the limulus test. The test was positive in three of the remaining 25 patients. Two of them had liver failure. The basic role that liver failure plays in the high level of endotoxin in the blood is discussed. The prognostic value of this test and the low correlation between bacteremia and endotoxemia are also commented on

UI MeSH Term Description Entries
D008033 Limulus Test Sensitive method for detection of bacterial endotoxins and endotoxin-like substances that depends on the in vitro gelation of Limulus amebocyte lysate (LAL), prepared from the circulating blood (amebocytes) of the horseshoe crab, by the endotoxin or related compound. Used for detection of endotoxin in body fluids and parenteral pharmaceuticals. Limulus Tests,Test, Limulus,Tests, Limulus
D008722 Methods A series of steps taken in order to conduct research. Techniques,Methodological Studies,Methodological Study,Procedures,Studies, Methodological,Study, Methodological,Method,Procedure,Technique
D004731 Endotoxins Toxins closely associated with the living cytoplasm or cell wall of certain microorganisms, which do not readily diffuse into the culture medium, but are released upon lysis of the cells. Endotoxin
D004755 Enterobacteriaceae A family of gram-negative, facultatively anaerobic, rod-shaped bacteria that do not form endospores. Its organisms are distributed worldwide with some being saprophytes and others being plant and animal parasites. Many species are of considerable economic importance due to their pathogenic effects on agriculture and livestock. Coliform Bacilli,Enterobacteria,Ewingella,Leclercia,Paracolobactrum,Sodalis

D012706 Serratia marcescens A species of gram-negative, facultatively anaerobic, rod-shaped bacteria found in soil, water, food, and clinical specimens. It is a prominent opportunistic pathogen for hospitalized patients.
D018805 Sepsis Systemic inflammatory response syndrome with a proven or suspected infectious etiology. When sepsis is associated with organ dysfunction distant from the site of infection, it is called severe sepsis. When sepsis is accompanied by HYPOTENSION despite adequate fluid infusion, it is called SEPTIC SHOCK.
