    Notes: A major problem in the intensive care unit nowadays is the development of multiple organ dysfunction syndrome (MODS), a cumulative sequence of progressive deterioration of organ functions. While the pathogenic pathways of MODS remain to be elucidated, it is assumed that cells of the host defence system, especially the macrophages, are altered in their function. During the development of MODS it is assumed that macrophages are overactivated and that an exaggerated inflammatory response may contribute to its pathogenesis. In order to gain insight into the alterations of the functional status of the macrophage during the development of MODS, a series of macrophage functions was measured in the subsequent phases of zymosan induced generalized inflammation in mice. Male C57BL/6 mice received a single dose of zymosan intraperitoneally and groups of animals were killed after 2, 5, 8, and 12 days. Peritoneal macrophages were collected for in vitro assessment of the ADCC, the production of superoxide (O−2) and nitric oxide (NO), and complement mediated phagocytosis and intracellular killing of Staphylococcus aureus. A single intraperitoneal injection with zymosan resulted in a three-phase illness. During the third phase the animals developed MODS-like symptoms. Peritoneal cells from control animals produced very low to non-detectable amounts of O−2 and NO, and the cytotoxic activity was also low. During the development of MODS, from day 7 onwards, the ability to produce O−2 and NO-2 became strongly elevated, as did the cytotoxic activity. These findings are in parallel with the development of MODS whereas the phagocytic and killing capacity remained essentially unaltered. The changes found could be detrimental for the organism, thus possibly contributing to the onset and development of MODS.

    Notes: Abstract Objective: To determine the value of the platelet count at admission for the assessment of the severity of disease in acute meningococcal infections. Design: Retrospective and prospective, descriptive patient study. Setting: University Hospital Intensive Care Unit (ICU). Patients: All patients (n = 92) with acute meningococcal disease from 1985 to 1997, who arrived at the ICU within 12 h after hospital admission and had more than one platelet count during the first 12 h. Measurements and results: After admission, platelets dropped in 95 % of the patients. At admission, 2/41 (5 %) of the non-hypotensive patients and 13/51 (25 %) of the hypotensive patients had platelets fewer than 100 × 109/l. During the following 12 h, these percentages increased to 15 % and 71 %, respectively. Fatalities had, at admission, a median platelet count of 111 × 109/l (range, 19–302 × 109/l), whereas the nadir, occurring at median 7.0 h (range, 1.3–12 h), was 31 × 109/l (range, 12–67 × 109/l). Plasma TNF, measured shortly after admission, correlated better with the platelet nadir (r = − 0.65, p 〈 0.0001) than with the platelet count at admission. Similarly, serum lactate correlated better with the platelet nadir. Conclusions: As platelets drop after admission, the use of the platelet count at admission for the assessment of the prognosis in acute meningococcal disease may be misleading. Frequently repeated platelet counts are a better tool for evaluating the severity of disease.

    Notes: Abstract  The interval from the time of admission to the emergency room until the administration of antibiotics in patients presenting with a serious infectious disease was analysed. Fifty patients presumptively diagnosed in the emergency room as having a serious infection (respiratory tract, urinary tract, erysipelas, fever with neutropenia or bacteremia) needing immediate empirical antibiotic treatment were enrolled in the study. A median interval from time of admission to administration of antibiotics of 5 hours was determined (range 0.6–13.3 h). The interval was significantly shorter in patients admitted at night than in patients admitted during office hours (3.7 vs. 6.0 h, P〈0.05). There was no difference with respect to the presenting features, body temperature, laboratory values at presentation or number of cultures performed. In 41 of the 50 patients blood samples were taken for culture. More than 80% of the patients received an antibiotic chosen in accordance with hospital guidelines. The analysis revealed that the median delay of 5 hours before patients received their initial dose of antibiotic depended on several factors. Attempts to provide optimal antimicrobial therapy should thus concentrate not only on the correct choice and dosage of a drug but also on prompt institution of therapy.
