OBJECTIVE: To look for relationships between the classification of sepsis and plasma cytokine concentrations. DESIGN: Prospective, consecutive entry study of patients meeting severe sepsis criteria and having bacteriologically documented infections. SETTING: University hospital, surgical intensive care unit. PATIENTS: Fifty consecutive patients developing severe sepsis or septic shock between December 1991 and December 1993. MEASUREMENTS AND MAIN RESULTS: Concentrations of tumor necrosis factor, interleukin (IL)-6, IL-8, and leukemia inhibitory factor were measured by immunoradiometric assay in the plasma of patients as soon as they developed severe sepsis or septic shock. Septic shock patients were divided into three groups in a blinded fashion (i.e., without knowing the results of the concentrations of cytokines), according to the presence of sustained hyperlactacidemia and to the rapidity of the onset of sepsis. Peak concentrations of all cytokines were statistically different between severe sepsis and septic shock patients. This finding was almost exclusively due to the data from patients with rapid onset of septic shock, who demonstrated very high but transient cytokine concentrations. Septic shock patients may thus have different profiles in the time course of their cytokine concentrations. The transient, high peak concentrations of cytokines were also related to transient leukopenia. Among the cytokines measured, IL-8 appeared to be the one that correlated best with lactacidemia, the presence of disseminated intravascular coagulation, severe hypoxemia, the Acute Physiology and Chronic Health Evaluation II score, and mortality rate. CONCLUSIONS: According to the profiles of the cytokines, septic shock patients do not represent a homogeneous population. These profiles should be described in order to distinguish between patients, and the profiles may be useful to identify those patients susceptible to new therapies. [less ▲]

The goal of this project was to find and collect high concentrations of endotoxin-specific antibodies for therapeutic IgG- or IgM-enriched preparations. Various enzyme-linked immunosorbent assays (ELISAs) were developed to perform longitudinal studies of the serological response to a large panel of smooth and rough purified lipopolysaccharide (LPS) extracts in a population of healthy blood donors. To accomplish this, 1612 human serum samples from volunteer blood donors collected by seven different blood banks in Belgium were screened and specific IgM and IgG activities were measured. Approximately 17% of the donors had anti-LPS concentrations higher than 40 mg L-1. Of these, 10.9% had anti-smooth LPS antibodies, 3.7% had anti-rough LPS antibodies and 2.8% were found to be positive towards both types of LPS. The mean anti-LPS antibody concentration was 8 mg L-1 for rough LPS and 14 mg L-1 for smooth LPS. Age- and sex-related distributions of the activities indicated that the greatest prevalence of high anti-LPS concentration was in women aged 40-49 years and in men older than 60 years. Differential absorption experiments showed that the pooled serum of selected blood donors contained a mixture of specific and cross-reacting antibodies. We detected predominantly anti-LPS activities due to the IgG1 and IgG2 subclasses. The range of specificities to different LPS was increased by the pooling of selected sera. It was concluded that pools of naturally occurring specific anti-LPS immunoglobulin antibodies may be obtained in Belgium by screening blood donors using ELISAs that we have developed. [less ▲]

-Le pied diabétique est la conséquence des altérations dégénératives du système vasculonerveux observées dans un diabète de longue durée. La neuropathie diabétique est le facteur essentiel dans la plupart des cas, responsable d'hypoalgésies, microtraumatismes et ulcérations, déformation du pied (amyotrophie), et d'une eutosympethectomie (peau sèche, fissurée). Une macroangiopathie (médiacalcinose, occlusions artérielles périphériques) n'est retrouvée que dans 30 % des cas. Une microangiopathie compromet la trophicité des tissus et ralentit leur cicatrisation. Enfin, tout diabétique présente une susceptibilité élevée aux infections. Cette multitude de facteurs en cause impose des mesures de prévention. Un équilibre du profil glycémique retardera les atteintes vasculo-nerveuses. L'hygiène du pied consistera en bains de pieds, soins d'ongles et d'hyperkératoses, chaussures adaptées. En cas de troubles trophiques, une décharge d'appui sers nécessaire. Une désinfection rigoureuse, associée à une antibiothérapie (après prélèvement, si possible) aidera à éviter l'évolution vers l'abcès profond. La moindre collection sera drainée, après excision large des tissus nécrotiques. Les nécroses sèches (talons, orteils) traduisent souvent une artériopethie, pour laquelle un geste de revascularisation (protondoolestie; pontage distal) pourra être pris en considération. Parfois, l'état septique du patient, ou l'étendue de la gangrène, imposera une amputation. L'approche du pied diabétique doit toujours être multidisciplinaire (diabétologue, dermatologue, orthésiste, orthopédiste, chirurgien vasculaire), et doit commencer par des mesures préventives.

Severe ketonuria developed during sedation with propofol in a 12 year old girl with brain injury. Deep sedation with propofol (5.1 mg/kg/h) was required because of agitation and severe intracranial hypertension; as a part of our management protocol, glucose intake was restricted to 5 Kcal/h. After 18 hours of propofol infusion there was intense ketonuria (8+ by Ketostix) without any evidence of metabolic acidosis (pH, HCO3- and anion gap were within normal values). At this time, indirect calorimetry (Deltatrac) confirmed that energy expenditure was principally based on fat consumption (70% of energy expenditure). Lowering the propofol infusion rate and increasing glucose intake reduced fat consumption to 39% within 8 hours: at this time, Ketostix was negative for ketone bodies. This case illustrates a potential risk of ketonuria during prolonged sedation with propofol (a 10% solution of intralipid), particularly if glucose intake is restricted. Monitoring urinary ketone bodies is recommended under these circumstances. [less ▲]

A four year child presented with an episode of malignant hyperthermia induced by reexposure to halothane. The episode was associated with early onset of a severe hypoglycemia and liver enzymatic perturbances. Etiology of these perturbances is hard to state precisely in this clinical context, but a hepatic toxicity of halothane and/or by dantrolene is considered. [less ▲]

This study compared performance of three heat and moisture exchangers (HME) during short-term postoperative mechanical ventilation. Temperature and absolute humidity (AH) were measured at various points of the ventilatory circuit. There was no statistical difference between the groups, regarding ambient and body To, body weight, fraction of inspired oxygen, tidal volume, and respiratory rate. Only the hygroscopic HME (groups 2 and 3) provide adequate conditioning with regard to AH and To of the inspiratory gases. The performance of hydrophobic HME (group 1) was inferior and appears to be unsatisfactory. Indirect evaluation (variations of inspiratory gases and tracheal temperatures, AH of the expired gases) confirmed the superiority of the hygroscopic HME. These data suggest that humidification of inspiratory gases with a hygroscopic HME is a defensible practice during short-term postoperative mechanical ventilation. Performance of hydrophobic HME may be weak and can expose the patient to an unacceptable risk of endotracheal tube occlusion. [less ▲]
