[Complement system during hemofiltration in patients with multiple organ failure].

Nine patients (8 men and 1 woman) were treated. Sepsis was diagnosed in 7 of them. All patients were subjected to forced ventilation of the lungs, 6 were in need of inotropic support. The severity of clinical status was 31 +/- 0.8 according to APACHE II score. One patient survived. The main method of substitute renal therapy (SRT) was permanent hemofiltration with spontaneous arteriovenous perfusion. The results indicate manifest depletion of the complement system augmenting with the progress of multiple organ failure (MOF). Extracorporeal perfusion in SRT had no additional negative effects on the complement system damaged by disease. Nonselective penetration of individual complement fractions into the filtrate in the course of perfusion was noted. Therefore, the complement system is severely damaged in patients with MOF; it can modulate the SRT because of penetration of its individual fractions.

[Role of oxygen venous saturation monitoring and CAVH in the multiple organ failure syndrome. Description of a clinical case].

A 42 year old man was admitted to the intensive Care Unit with signs and symptoms of septic shock, associated with adult respiratory distress syndrome (ARDS), jaundice and acute renal failure. In order to support different organs failures mechanical ventilation (IPPV, PSV, CPAP), continuous arteriovenous hemofiltration were affected, and continuous intravenous infusion of dopamine and dobutamine was started. After and during application of these therapeutic measures, continuous monitoring of mixed venous blood oxygen saturation (SvO2) was applied by Swan-Ganz fiber optic catheter in the pulmonary artery. Monitoring of SvO2 represented a useful means to guide inotropic therapy and to assess the hemodynamic effects of CAVH and mechanical ventilation. The case reported emphasized the role of continuous venous oximetry in multiple organ failure syndrome.

Strong vasopressor support may be futile in the intensive care unit patient with multiple organ failure.

OBJECTIVE: The aim of the study was to determine the prognosis in patients who needed norepinephrine treatment in our institution in relation to the degree of organ failure and the evolution of the disease process. DESIGN: Retrospective case note analysis of outcome of those patients who needed norepinephrine according to our institutional regimen. PATIENTS: A total of 100 consecutive patients admitted to our 31-bed medical-surgical intensive care unit (ICU) who were treated with norepinephrine for severe hypotension and evidence of end-organ hypoperfusion unresponsive to both fluid resuscitation and dopamine treatment at 20 microg/kg/min. MEASUREMENTS: The degree of organ dysfunction at the time of starting norepinephrine treatment was assessed by the sequential organ failure assessment (SOFA) score. The time before starting norepinephrine treatment was defined as the time elapsed between ICU admission and that of starting norepinephrine administration. The patients were defined as survivors or nonsurvivors according to their ICU outcome. RESULTS: There were relationships between mortality and the degree of organ dysfunction and mortality and the duration of ICU stay before starting norepinephrine treatment. The mortality rate was 100% in the 30 patients with a total SOFA score of >12 and a delay before starting norepinephrine treatment of >1 day. The mortality rate of the other patients was 63%. The lowest mortality was seen in patients with lower SOFA scores and early norepinephrine administration after admission. CONCLUSIONS: Both the time of starting norepinephrine treatment after admission to the ICU and the degree of organ dysfunction have an important bearing on subsequent outcome. Although norepinephrine may be a lifesaving catecholamine in some cases, its administration to patients who have already developed multiple organ failure during their stay in the ICU is associated with a poor outcome.

Lipid composition and lipopolysaccharide binding capacity of lipoproteins in plasma and lymph of patients with systemic inflammatory response syndrome and multiple organ failure.

BACKGROUND: Lipopolysaccharide (LPS), the major glycolipid component of Gram-negative bacterial outer membranes, is a potent endotoxin responsible for many of the directly or indirectly induced symptoms of infection. Lipoproteins (in particular, high-density lipoproteins) sequester LPS, thereby acting as a humoral detoxification mechanism. PATIENTS: Differences in the lipoprotein composition in human plasma and lymph of a control patient group (n = 5) without systemic inflammatory response syndrome (non-SIRS/MOF) and patients with SIRS and multiple organ failure (MOF, n = 9) were studied. The LPS binding capacity of the lipoproteins in SIRS/MOF and non-SIRS/MOF patients was investigated by rechallenge of the plasma and lymph with fluorescently labeled LPS ex vivo. The lipoprotein composition was analyzed using immunochemical techniques and high-performance gel permeation chromatography. RESULTS: In the non-SIRS/MOF patient group, plasma and lymph levels of apolipoprotein A-I (600 and 450 mg/L, respectively), apolipoprotein B (440 and 280 mg/L, respectively), total cholesterol (2.88 and 1.05 mM, respectively), and total triglycerides (0.67 and 0.97 mM, respectively) were observed. In the SIRS/MOF group, a decrease of apolipoprotein A-I (-55% in plasma and lymph), a decrease of apolipoprotein B (-43% in plasma and -38% in lymph), and a decrease of total cholesterol levels (-54% in plasma and -37% in lymph) were demonstrated. However, the triglyceride levels in the SIRS/MOF group showed a 30% increase in plasma and a 47% decrease in lymph compared with the non-SIRS/MOF patients. In SIRS/MOF patients, a 2.8-fold increase in plasma and a 1.8-fold increase in lymph of the LPS low-density lipoprotein/high-density lipoprotein ratio was observed, indicating that the relative LPS binding capacity of the lipoproteins in the SIRS/MOF patient group showed a trend to be shifted mainly toward low-density lipoproteins. Furthermore, in plasma and lymph of four SIRS/MOF patients, a novel cholesterol-containing high-density lipoprotein-like particle was found that barely had LPS binding capacity (<5%). CONCLUSIONS: In the SIRS/MOF patients, the changes in lipoprotein composition in lymph are a reflection of those in plasma, except for the triglyceride levels. In comparison with the non-SIRS/MOF patients, the SIRS/MOF patients show a shifted LPS binding capacity of high-density lipoproteins toward low-density lipoproteins in plasma and in lymph. Moreover, in plasma and lymph, novel cholesterol-containing particles, resembling high-density lipoprotein, were identified in the SIRS/MOF patient group.

Anti-inflammatory cytokine response and the development of multiple organ failure in severe sepsis.

BACKGROUND: The production of proinflammatory cytokines activates the systemic inflammatory response in sepsis. Patients also develop a compensatory anti-inflammatory reaction, which may have an important down-regulatory effect on the overactive inflammation. However, the role of this anti-inflammatory response in sepsis is not completely clarified. In this prospective study, we investigated the relationship between the pro- and anti-inflammatory cytokine profiles in severe sepsis and their role in the development of multiple organ failure (MOF). METHODS: Thirty-eight patients meeting the criteria for severe sepsis were studied. MOF was defined as a maximum SOFA score of 10 or higher. Serial measurements of the proinflammatory IL-6 and IL-1beta and the anti-inflammatory IL-10 and IL-1ra were used. The cytokine samples were taken at the onset of sepsis and on the third and fifth day during the ICU period. RESULTS: The initial IL-10 and IL-1ra responses were identical in patients with or without MOF. The anti-inflammatory cytokine levels remained elevated in the MOF patients, whereas in patients without MOF the levels declined. The IL-6/IL-10 ratio was significantly higher in the MOF patients on days 1 and 3 compared with patients without MOF. CONCLUSIONS: We could not demonstrate overproduction of anti-inflammatory IL-10 in MOF patients. On the contrary, the high IL-6/IL-10 ratio indicates that IL-10 deficiency may contribute to the development of MOF in severe sepsis.

Multiple organ failure and prognosis in adult patients with diabetic ketoacidosis.

OBJECTIVE: Evaluation of prognostic factors of patients presenting with diabetic ketoacidosis (DKA) at an emergency department. DESIGN: Retrospective cohort study. SETTING: The Emergency Department of the Vienna General Hospital, a 2000-bed tertiary care hospital. PATIENTS AND PARTICIPANTS: Patients with DKA admitted from January 1, 1994 to September 30, 1998. INTERVENTIONS: Treatment of DKA in accordance with a predefined regimen. MEASUREMENTS AND RESULTS: History, clinical findings, biochemical parameters, blood gas analysis, multiorgan failure score (MOF) and treatment modalities were assessed. Patients were followed until death or hospital discharge. For group comparison the Mann Whitney U-test was used. Within the study period 21 patients were admitted because of diabetic ketoacidosis (female: 10, median age: 42 years; 31 to 58). All patients suffered from insulin-dependent diabetes mellitus and were treated according to a standardised protocol. Six patients (29%) died in hospital. The non-survivors had significantly higher MOF-scores on admission (5 vs. 2, p < 0.001) and after 24 hours (4 vs. 0, p < 0.01) of intensive care treatment. Additionally, non-survivors had significantly higher levels of GOT (64 vs. 8 U/l), GPT (28 vs. 11 U/l), BUN (34.63 vs. 12.14 mmol/l), creatinine (291.7 vs. 150.3 mmol/l), amylase (315 vs. 78 U/l) and lipase (573 vs. 122 U/l) on admission than did survivors (p < 0.05), and also had a significantly higher net positive fluid balance after 24 hours (8.0 vs. 4.75 l, p < 0.05). All other parameters were not significantly different between the groups. CONCLUSION: Multiple organ failure may develop in patients with diabetic ketoacidosis and is associated with poor prognosis.

A shock toxin that produces disseminated intravascular coagulation and multiple organ failure.

OBJECTIVE: To introduce a new concept in the etiology and treatment of traumatic and septic shock. It describes 3 types of shock: (1) hypovolemic shock, (2) traumatic shock, and (3) septic shock. BACKGROUND: The mortality of septic shock in both total number and mortality rate has been increasing over the past 40 years despite major advances in diagnosis and treatment, including a number of "magic bullets." Trauma is the No. 1 cause of death in persons under the age of 44 and the No. 3 cause of all deaths. Traumatic shock has been assumed to be caused by hypovolemia; however, many traumatic shock patients die with a normal blood volume, usually after several days. Septic shock in pigs using an injection of killed Escherichia coli organisms produced disseminated intravascular coagulation (DIC). Control pigs treated with plasminogen activator survived. Septic shock in humans also treated with plasminogen activator showed excellent results. Traumatic shock studied in pigs showed excellent results with plasminogen activator. A normal blood volume was maintained with the use of intravenous fluids. Traumatic shock in humans also treated by plasminogen activator showed excellent results. The improvement in PaO2 and other parameters demonstrated in these studies provides a new possibility in the treatment of trauma and/or sepsis induced acute respiratory distress syndrome (ARDS). DIC is almost always present in traumatic and septic shock and probably in the course of ARDS and multiple organ failure. The DIC is probably initiated by tissue cell or bacterial cell destruction, which liberates a thrombogenic aminophospholipid that forms the inner layer of all cell walls.

Multiple organ failure and coma as initial presentation of pheochromocytoma in a patient with multiple endocrine neoplasia (MEN) type II A.

The unusual case of a 65-year-old woman with intermittent hypotension, fever, pulmonary edema and coma as initial presentation of pheochromocytoma is reported. The patient developed respiratory, cardiac and renal failure, disseminated intravascular coagulation and liver dysfunction. She had to be defibrillated on multiple occasions, occurring in periods of severe hypertension. After successful surgical removal of a pheochromocytoma a thyroid medullary carcinoma was detected. Several members of the patients family had presented with multiple endocrine neoplasia (MEN II).

Hypertonic volume therapy: feasibility in the prevention and treatment of multiple organ failure and sepsis.

Small-volume resuscitation by means of bolus infusion of hypertonic saline solutions was first applied for the primary treatment of severe hemorrhagic and traumatic shock and promptly restored central hemodynamics and regional organ blood flow. Mechanisms of action are diverse--i. maintenance of high cardiac output (direct myocardial stimulation; increase in intravascular volume); ii. maintenance of peripheral arterial vasodilation (effect of hyperosmolality; plasma volume effect) and iii. reduction of tissue edema (shifting of tissue water along the osmotic gradient). These mechanisms promote the restoration of the severely impaired microcirculation frequently seen also in sepsis. Hypertonic volume therapy has been the object of several experimental studies of acute hyperdynamic endotoxemia, however, a greater number of clinical studies have to be developed for the better understanding of the positive, and perhaps hazardous, effects of small-volume resuscitation in sepsis and multiple organ failure. The aim of this paper is to review the concepts involving such solutions, and their potential use in treatment of profound hypovolemia and microcirculatory deterioration associated with sepsis and endotoxic shock.

[Pathophysiology and treatment of multiple organ failure among hepatectomized cirrhotic patients].

Our previous studies have claimed that cirrhotic rats, induced with CCl4, showed depressed reticuloendothelial system (RES) function and increased susceptibility to infection. We have also shown that OK-432, a non-specific immunopotentiator, and ATP-MgCl2, which improves depressed intracellular energy metabolism, improve RES function of cirrhotic rats and that thereby improve survival following peritonitis or hepatectomy. The present study was undertaken to investigate whether OK-432 or ATP-MgCl2 could be beneficial for the prevention of multiple organ failure (MOF) following hepatectomy among the cirrhotics. The cirrhotics with hepatocellular carcinoma, who underwent partial hepatectomy (segmentectomy or subsegmentectomy) were given OK-432 (5 KE/day for 4 days) preoperatively or ATP-MgCl2 (50 mumole/kg) within 24 hours following the operation. The rates of postoperative pulmonary complication and the operative mortality were compared among OK-432 group, ATP-MgCl2 group and controls. The rates of posthepatectomy pulmonary complication and operative mortality were decreased with these treatments compared to the controls. The RES function was also improved with these treatments. These data suggest that the cirrhotic patients are the immunocompromised hosts showing the depressed RES function and that the enhancement of RES function with OK-432 or ATP-MgCl2 is beneficial for the prevention of posthepatectomy MOF among cirrhotics.

Early veno-venous haemodiafiltration for sepsis-related multiple organ failure.

INTRODUCTION: We conducted a prospective observational study from January 1995 to December 2004 to evaluate the impact on recovery of a major advance in renal replacement therapy, namely continuous veno-venous haemodiafiltration (CVVHDF), in patients with refractory septic shock. METHOD: CVVHDF was implemented after 6-12 hours of maximal haemodynamic support, and base excess monitoring was used to evaluate the improvement achieved. Of the 60 patients studied, 40 had improved metabolic acidosis after 12 hours of CVVHDF, with a progressive improvement in all failing organs; the final mortality rate in this subgroup was 30%. In contrast, metabolic acidosis did not improve in the remaining 20 patients after 12 hours of CVVHDF, and the mortality rate in this subgroup was 100%. The crude mortality rate for the whole group was 53%, which is significantly lower than the predicted mortality using Simplified Acute Physiology Score II (79%). CONCLUSION: Early CVVHDF may improve the prognosis of sepsis-related multiple organ failure. Failure to correct metabolic acidosis rapidly during the procedure was a strong predictor of mortality.

[Multiple organ failure following inhalation of butane gas: a case report].

Most cases of acute poisoning by butane and other volatile compounds occur in young people as a consequence of substance abuse by inhalation. Clinical symptoms are caused by asphyxia and mainly affect the cardiovascular, respiratory and central nervous system. There are also reported deaths from intoxication of butane inhalation, mostly by cardiac arrhythmia. We report the case of a healthy 14 year-old boy who inhaled butane gas from an aerosol can for refilling cigarette lighters. Despite successful resuscitation and defibrillation, he died two days later from multiple organ failure involving the central nervous system, cardiovascular system, pulmonary system and the liver. Although such incidents are rare in middle European countries, emergency and intensive care medicine staff should be instructed on the consequences and management of butane gas poisoning.

Neostigmine resolves critical illness-related colonic ileus in intensive care patients with multiple organ failure--a prospective, double-blind, placebo-controlled trial.

OBJECTIVE: Critical illness-related colonic ileus (CIRCI) is characterized by the non-passage of stools in critically ill patients as a result of the absence of prokinetic movements of the colon, while the upper gastrointestinal tract functions properly and mechanical ileus is absent: We investigated whether neostigmine resulted in defecation in patients with CIRCI. DESIGN: Double-blinded, placebo-controlled prospective study. SETTING: Eighteen-bed intensive care unit. PATIENTS: Thirty ventilated patients with multiple organ failure with CIRCI for > 3 days. INTERVENTION: Continuous intravenous administration of neostigmine 0.4-0.8 mg/h over 24 h, or placebo. MEASUREMENTS AND RESULTS: Time to first defecation and adverse reactions were recorded. Thirty patients were randomized, 24 could be evaluated. The mean prestudy time was 5 days, mean APACHE II score on admission was 23.2, and mean MOF score on the day of the study was 6.4. Of the 13 patients receiving neostigmine, 11 passed stools, whereas none of the placebo-treated patients passed stools (P < 0.001). After 24 h, the non-responders received in a cross-over fashion neostigmine or placebo respectively. Eight out of the 11 neostigmine patients now passed stools (mean 11.4 h), and none of the placebo patients. Overall, in none of the patients did passage of stools occur during placebo infusion, whereas 19 of the 24 neostigmine-treated patients had defecation (79%). No acute serious adverse effects occurred, but three patients had ischemic colonic complications 7-10 days after treatment. CONCLUSION: Continuous infusion of 0.4-0.8 mg/h of neostigmine promotes defecation in ICU patients with a colonic ileus without important adverse reactions.
