Respiratory failure accompanied by cardiac failure occurs mostly due to decreased PaO2. However, sometimes we encounter patients with cardiac failure having on increase of PaCO2, who develop CO2 narcosis in the ICU. In this study we evaluated hypoventilation respiratory failure in patients with cardiac failure. Seventy-six patients with both respiratory failure and cardiac failure caused by intrinsic heart disease, who required mechanical ventilation in the ICU were studied. The patients were divided into 2 groups; hypoxic respiratory failure group (n = 53) and hypoventilation respiratory failure group (n = 23). Blood gas analysis and cardiovascular hemodynamics including arterial blood pressure, heart rate and Swan-Ganz catheter findings were performed before, during and after mechanical ventilation in each patient. Mortality rate and its relation to hemodynamic variables were also evaluated in each group. In both groups even when it was possible to maintain oxygenation capacity by conducting mechanical ventilation against severe respiratory failure, what can be said about the prognosis is that it depended totally on the improvement of cardiac function. The mechanism by which hypoxemia is displayed due to cardiogenic pulmonary edema is already well known, but in regard to the mechanism of hypercapnia in cases with hypersensitivity of the airways it is thought that through induction of cardiogenic pulmonary edema bronchial spasms is induced, and this causes hypercapnia. However, it is also possible to consider cardiac asthma as the cause. Among respiratory failure cases due to cardiogenic pulmonary edema that occurs in association with heart failure, there is both hypoxic respiratory failure as well as hypoventilation respiratory failure.(ABSTRACT TRUNCATED AT 250 WORDS)
BACKGROUND: This section is under preparation and will be included in the next issue. OBJECTIVES: To determine whether, in preterm newborn infants who have hypoxic respiratory failure, treatment with inhaled nitric oxide improves oxygenation and reduces the rates of death, or adverse neurodevelopmental outcome. SEARCH STRATEGY: Electronic and hand searching of pediatric/neonatal literature and personal data files. SELECTION CRITERIA: Randomized and quasi randomized studies in preterm infants with hypoxic respiratory failure. Administration of inhaled nitric oxide. Clinically relevant outcomes, including death, oxygenation, intraventricular haemorrhage. DATA COLLECTION AND ANALYSIS: One randomized controlled trial of nitric oxide therapy was found in preterm infants with a high risk of developing bronchopulmonary dysplasia (Subhedar 1997). MAIN RESULTS: No significant effect of inhaled nitric oxide on any outcome variable was found. In particular there was no effect on the primary outcome variable of death or bronchopulmonary dysplasia. REVIEWER'S CONCLUSIONS: There is currently no published information to support the use of inhaled nitric oxide in preterm infants. Preterm infants should not be treated with inhaled nitric oxide except in the context of prospective, randomized controlled trials.
BACKGROUND: Digitalis glycosides have been in clinical use in the treatment of congestive heart failure for more than 200 years. In recent years several trials have been conducted to address concerns about efficacy and toxicity. Although a systematic review of the literature was recently published, an update is required to include more current trials. OBJECTIVES: To examine the effectiveness of digitalis glycosides in treating congestive heart failure in patients with normal sinus rhythm. To examine the effect of digitalis in patients taking diuretics, ACE inhibitors, and beta blockers; patients with varying severity and duration of disease; patients with prior exposure to digitalis vs. no prior exposure; and patients with diastolic vs. systolic dysfunction. SEARCH STRATEGY: Electronic databases were searched between 1966 and 2000. Dissertation Abstracts and annual meeting abstracts of the American Heart Association, American College of Cardiology, and European Society of Cardiology were searched from 1996-2000. In addition, reference lists provided by the pharmaceutical industry (Glaxo Wellcome Inc.) were searched. SELECTION CRITERIA: Included were randomized placebo-controlled trials of 20 or more adult patients of either sex with symptomatic congestive heart failure who were studied for seven weeks or more. Excluded were trials in which the prevalence of atrial fibrillation was 2% or greater, or in which any arrhythmia that might compromise cardiac function or any potentially reversible cause of heart failure such as acute ischemic heart disease or myocarditis was present. DATA COLLECTION AND ANALYSIS: Articles selected from the searches described above were reviewed by one of the coauthors, and validated by staff from the central office of the Heart Collaborative Review Group in Bristol, UK. MAIN RESULTS: Eleven articles meeting the defined criteria were identified, and major endpoints of mortality, hospitalization, and clinical status, based respectively upon on 8, 4, and 10 of these selected studies, were recorded and analyzed. The data show that there is no difference in mortality between treatment and control groups, whereas digitalis therapy is associated with a lower rate of hospitalization and of clinical deterioration. REVIEWER'S CONCLUSIONS: The literature indicates that digitalis has a useful role in the treatment of patients with congestive heart failure who are in normal sinus rhythm.
BACKGROUND: The EUROHEART programme is a rolling programme of cardiovascular surveys among the member nations of the European Society of Cardiology (ESC). These surveys will provide information on the nature of cardiovascular disease and its management. This manuscript describes a survey into the nature and management of heart failure. AIMS: The EuroHeart Failure survey aims to describe the quality of hospital care, diagnostic and therapeutic, for patients with suspected or confirmed heart failure in ESC member countries. Patients will be interviewed subsequent to hospital discharge to assess their understanding of their condition, side effects from and their compliance with therapy and their satisfaction with the management for heart failure. The quality of management will be judged against the recommendations contained in the ESC guidelines on diagnosis and treatment of heart failure. Outcome will be further assessed by repeat interviews in 6-12 months time. A further survey of heart failure in 2001/2002 is also planned. METHODS: A prospective survey of all deaths and discharges from medical (cardiology, internal medicine and geriatric medicine) and cardiac surgical wards to identify patients with heart failure, suspected or confirmed. Approximately 70 hospital clusters, comprising two to six hospitals in each cluster, in 24 member countries of the ESC are conducting the study. At the time of writing, approximately 30000 deaths and discharges have been screened and approximately 4000 patients have been enrolled. CONCLUSIONS: The EuroHeart Survey will allow actual practice to be compared to ESC guidelines on the diagnosis and treatment of heart failure. The surveys and guidelines should prove mutually informative. The main EuroHeart Failure project will be completed by late 2000. However, new centres volunteering to participate in the study (contact corresponding author) may be accepted providing they have the necessary research personnel and provided funding can be agreed for statistical support and administration.
BACKGROUND: The multidisciplinary approach to managing heart failure has been shown to improve outcomes. The role of a clinical pharmacist in treating heart failure has not been evaluated. METHODS: One hundred eighty-one patients with heart failure and left ventricular dysfunction (ejection fraction <45) undergoing evaluation in clinic were randomized to an intervention or a control group. Patients in the intervention group received clinical pharmacist evaluation, which included medication evaluation, therapeutic recommendations to the attending physician, patient education, and follow-up telemonitoring. The control group received usual care. The primary end point was combined all-cause mortality and heart failure clinical events. All clinical events were adjudicated by a blinded end point committee. RESULTS: Baseline characteristics were similar except for slightly higher age in the intervention group. Median follow-up was 6 months. All-cause mortality and heart failure events were significantly lower in the intervention group compared with the control group (4 vs 16; P= .005). In addition, patients in the intervention group received higher angiotensin-converting enzyme inhibitor doses as reflected by the median fraction of target reached (25th and 75th percentiles), 1.0 (0.5 and 1) and 0.5 (0.1875 and 1) in the intervention and control groups, respectively (P<.001). The use of other vasodilators in angiotensin-converting enzyme inhibitor-intolerant patients was higher in the intervention group (75% vs 26%; P= .02). CONCLUSIONS: Outcomes in heart failure can be improved with a clinical pharmacist as a member of the multidisciplinary heart failure team. This observation may be due to higher doses of angiotensin-converting enzyme inhibitors and/or closer follow-up.
Data from small studies have suggested the presence of platelet abnormalities in patients with congestive heart failure (CHF). We sought to characterize the diagnostic utility of different platelet parameters and platelet-endothelial biomarkers in a random outpatient CHF population investigated in the EPCOT ('Whole Blood Impedance Aggregometry for the Assessment of Platelet Function in Patients with Congestive Heart Failure') Trial. Blood samples were obtained for measurement of platelet contractile force (PCF), whole blood aggregation, shear-induced closure time, expression of glycoprotein (GP) IIb/IIIa, and P-selectin in 100 consecutive patients with CHF. Substantial interindividual variability of platelet characteristics exists in patients with CHF. There were no statistically significant differences when patients were grouped according to incidence of vascular events, emergency revascularization needs, survival, or etiology of heart failure. Aspirin use did not affect instrument readings either. PCF correlates very poorly with whole blood aggregometry (r(2) = 0.023), closure time (r(2) = 0.028), platelet GP IIb/IIIa (r(2) = 0.0028), and P-selectin (r(2) = 0.002) expression. Furthermore, there was no correlation with brain natriuretic peptide concentrations, a marker of severity and prognosis in heart failure reflecting the neurohumoral status. Patients with heart failure enrolled in the EPCOT Trial exhibited a marginal, sometimes oppositely directed change in platelet function, challenging the diagnostic utility of these platelet parameters and biomarkers to serve as useful tools for the identification of platelet abnormalities, for predicting clinical outcomes, or for monitoring antiplatelet strategies in this population. The usefulness of these measurements for assessing platelets in the different clinical settings remains to be explored. Taken together, opposite to our expectations, major clinical characteristics of heart failure did not correlate well with the platelet characteristics investigated in this study.
BACKGROUND: This section is under preparation and will be included in the next issue. OBJECTIVES: To determine whether treatment of hypoxemic newborn infants with inhaled nitric oxide (INO) improves oxygenation and reduces the rates of death, or the requirement for ECMO. SEARCH STRATEGY: Electronic and hand searching of pediatric/neonatal literature and personal data files. In addition we contacted the principal investigators of articles which have been published as abstracts to ascertain the necessary information. SELECTION CRITERIA: Randomized and quasi randomized studies in term and near term infants. Administration of inhaled nitric oxide. Clinically relevant outcomes, including death, requirement for ECMO, and oxygenation. DATA COLLECTION AND ANALYSIS: Eight randomized controlled studies were found in term and near term infants with hypoxia. Entry criteria were reasonably consistent except for the one trial that studied only infants with congenital diaphragmatic hernia (Ninos 1997). MAIN RESULTS: Inhaled nitric oxide appears to improve outcome in hypoxemic term and near term infants by reducing the incidence of the combined endpoint of death or need for ECMO. The reduction seems to be entirely a reduction in need for ECMO; mortality is not reduced. Oxygenation improves in approximately 50% of infants receiving nitric oxide. The Oxygenation Index decreases by a (weighted) mean of 15.1 within 30 to 60 minutes after commencing therapy and PaO2 increases by a mean of 53 mmHg. It does not appear to affect outcome whether infants have clear echocardiographic evidence of PPHN or not. The outcome of infants with diaphragmatic hernia was not improved; indeed there is a suggestion that outcome was slightly worsened. REVIEWER'S CONCLUSIONS: On the evidence presently available, it appears reasonable to use inhaled nitric oxide in a concentration of 20 ppm for term and near term infants with hypoxic respiratory failure who do not have a diaphragmatic hernia. Longterm neurodevelopmental and pulmonary followup of surviving infants enrolled in randomized trials of INO are required to establish more firmly the role of INO in the treatment of neonatal respiratory failure.
Commonly prescribed antiarrhythmic agents--and several recently developed agents--are reviewed with respect to their use in patients with renal failure, hepatic failure, and congestive heart failure. Because removal of electrophysiologically active agents from the systemic circulation in most cases depends on either renal elimination, hepatic metabolism, or both, patients with preexisting kidney or liver disease may be at increased risk of treatment-related drug toxicity, including proarrhythmia. These susceptibilities should be anticipated, with drug selection and/or dosage modified accordingly. Patients with left ventricular dysfunction and heart failure also are at increased risk of treatment-related complications, including proarrhythmia and hemodynamic intolerance. In addition, the metabolism of antiarrhythmic drugs may be impaired in these patients. Preference should be given to drugs with a proven safety profile, such as amiodarone, in patients with heart failure.
BACKGROUND: Heart failure in blacks has been associated with a poorer prognosis than in whites. In such diseases as hypertension, blacks show pathophysiological differences and respond differently to some therapies than whites. The aim of this study is to evaluate the clinical characteristics and response to therapy of black compared with white patients with heart failure. METHODS AND RESULTS: In the first Vasodilator-Heart Failure Trial (V-HeFT I), 180 black male patients were compared with 450 white male patients for baseline characteristics, prognosis, and response to therapy. In V-HeFT II, the same comparisons were made for 215 black and 574 white male patients, including an analysis stratified by the presence or absence of a history of hypertension. In both trials, black patients had a lower incidence of coronary artery disease, greater incidence of previous hypertension, and a greater cardiothoracic ratio (P < .05) than white patients. In V-HeFT II, plasma norepinephrine levels were significantly less in blacks; plasma renin activity was less only in blacks with a history of hypertension. Overall mortality or hospitalization for congestive heart failure did not differ between blacks and whites in the placebo group in V-HeFT I. However, the mortality of black patients receiving hydralazine plus isosorbide dinitrate (H-I) was reduced (P = .04) in V-HeFT I, whereas white patients showed no difference from placebo. In V-HeFT II, only white patients showed a mortality reduction from enalapril therapy compared with H-I therapy (P = .02). Whites also showed evidence of greater blood pressure reduction and enhanced regression of cardiac size in response to enalapril. When stratified by history of hypertension in V-HeFT II, only whites with a history of hypertension, who had greater renin levels, showed significant mortality reduction with enalapril compared with H-I therapy. Hospitalization rates did not differ between treatment groups in either study. CONCLUSION: Whites and blacks showed differences in cause, neurohormonal stimulation, and pharmacological response in heart failure. This retrospective analysis suggests angiotensin-converting enzyme inhibitors are particularly effective in whites, and the H-I combination can be equally effective in blacks. Prospective trials involving large numbers of black patients are needed to further clarify their response to therapy.
Fractional hydrolysis and acetylation of procainamide, acetylation of procainamide-derived p-aminobenzoic acid and plasma hydrolysis of procaine were studied in 20 patients with chronic heart failure (CHF), 20 patients with chronic respiratory insufficiency (CRI) and 20 patients with chronic renal failure (RF). The results were compared with those obtained in a group of 20 normal volunteers. Hydrolysis of procainamide and procaine were reduced in patients with CHF and CRI, but not in patients with RF. Moreover, more marked decreases in procainamide and procaine hydrolysis were seen in subgroups with secondary hepatic dysfunction. The diminution of hydrolysis of procainamide was not paralleled by changes in acetylation of procainamide or p-aminobenzoic acid. It is concluded that in patients with hepatic involvement secondary to advanced CHF or CRI, hepatic and plasmatic hydrolysis activity is decreased to a degree equivalent to primary liver failure.
Because results of pathogen identification are often lacking when antibiotic therapy is initiated, treatment must frequently be instituted on an empirical basis. The type of empirical therapy will depend on the anticipated pathogen spectrum and naturally also on the prevailing resistance patterns. Inadequate antibiotic therapy may not only be associated with increased overall treatment costs, but will also have adverse effects on mortality. The clinician is frequently faced with an overabundant variety of microbiological data and may fail to interpret them correctly. Therefore, the present study has attempted to "translate" the available microbiological resistance data, frequently presented in the form of percentage rates, into concrete patient numbers and thus illustrate the frequency of inadequate antibiotic therapy. For this purpose, "Indication Failure" (IF), "Cumulative Indication Failure" (CIF) and "Balanced Indication Failure" (BIF) have been calculated based on available microbiological data. For the indication "nosocomial pneumonia", calculations of the BIF show that only one out of 67 or one out of 63 patients is inadequately treated with a therapy with cefepime or imipenem, while one out of 25 patients is inadequately treated when using ceftazidime. However, it must be pointed out that these calculations only represent an interpretation of microbiological data and the success of antibiotic therapy will ultimately also depend on parameters such as the pharmacodynamic properties of an antibiotic or on the immunocompetence of the patient treated.
Growth retardation in children with chronic renal failure (CRF) is partly due to an inhibition of insulin-like growth factor (IGF) activity by an excess of high-affinity IGF-binding proteins (IGFBPs). The aim of this study was to analyze the serum levels and forms of IGFBP-4 and IGFBP-5 in CRF patients using specific, recently developed radioimmunoassays (RIAs) and immunoblot analysis. We examined 89 children [age 11.5 (2.8-19.0) years] with CRF [glomerular filtration rate 26.6 (7.0-67.4) ml/min per 1.73 m2], nine of them with end-stage renal disease undergoing peritoneal dialysis. Serum-immunoreactive IGFBP-4 levels were fourfold increased in CRF (prepubertal 1080+/-268 ng/ml; pubertal 989+/-299 ng/ml) compared to healthy prepubertal controls (265+/-73 ng/ml). In contrast, serum IGFBP-5 levels were not significantly increased neither in prepubertal (361+/-120 ng/ml vs 282+/-75 ng/ml in controls) nor pubertal CRF children (478+/-165 ng/ml vs 491+/-80 ng/ml in controls). Immunoblot analysis showed the presence of intact as well as fragmented IGFBP-4 and IGFBP-5. Serum IGFBP-4, but not IGFBP-5, levels were inversely correlated with GFR (r=-0.39, P<0.001). In prepubertal children, IGFBP-4 levels were inversely correlated with standardized height (r=-0.40; P<0.005). In contrast, IGFBP-5 levels were positively correlated both with standardized height (r=0.32, P<0.02) and baseline height velocity (r=0.45, P<0.005). A 3-month therapy with rhGH stimulated serum IGFBP-5 levels by 43% (P<0.01); there was no consistent effect on IGFBP-4 levels. There was a positive correlation between IGFBP-4 and IGFBP-2 (r=0.46, P<0.001); IGFBP-5 was positively correlated with IGF-I (r=0.59, P<0.001), IGF-II(r=0.42, P<0.001)and IGFBP-3 (r=0.47, P<0.001) and inversely correlated with IGFBP-1 (r=-0.41, P<0.001). In summary, serum IGFBP-4 is fourfold elevated in children with CRF in relation to the degree of renal dysfunction and contributes to the marked increase in IGF-binding capacity in CRF serum. The inverse correlation of serum IGFBP-4 with standardized height is consistent with its role as another inhibitor of the biological action of the IGFs on growth plate cartilage. In contrast, serum IGFBP-5 is not elevated in CRF serum and circulates mainly as proteolysed fragments. The positive correlation of serum IGFBP-5 with growth and its increase during GH therapy indicate that IGFBP-5 is a stimulatory IGFBP in patients with CRF, either by enhancing IGF activity through better presentation of TGF to its receptor or by an IGF-independent effect through activation of a specific, recently described putative IGFBP-5-receptor.
BACKGROUND: Previous studies of pacing therapy for dilated congestive heart failure (CHF) have not established the relative importance of pacing site, AV delay, and patient heterogeneity on outcome. These variables were compared by a novel technique that evaluated immediate changes in hemodynamic function during brief periods of atrial-synchronous ventricular pacing. METHODS AND RESULTS: Twenty-seven CHF patients with severe left ventricular (LV) systolic dysfunction and LV conduction disorder were implanted with endocardial pacing leads in the right atrium and right ventricle (RV) and an epicardial lead on the LV and instrumented with micromanometer catheters in the LV, aorta, and RV. Patients in normal sinus rhythm were stimulated in the RV, LV, or both ventricles simultaneously (BV) at preselected AV delays in a repeating 5-paced/15-nonpaced beat sequence. Maximum LV pressure derivative (LV+dP/dt) and aortic pulse pressure (PP) changed immediately at pacing onset, increasing at a patient-specific optimal AV delay in 20 patients with wide surface QRS (180+/-22 ms) and decreasing at short AV delays in 5 patients with narrower QRS (128+/-12 ms) (P<0.0001). Overall, BV and LV pacing increased LV+dP/dt and PP more than RV pacing (P<0.01), whereas LV pacing increased LV+dP/dt more than BV pacing (P<0.01). CONCLUSIONS: In this population, CHF patients with sufficiently wide surface QRS benefit from atrial-synchronous ventricular pacing, LV stimulation is required for maximum acute benefit, and the maximum benefit at any site occurs with a patient-specific AV delay.
Growth retardation in children with chronic renal failure (CRF) despite normal or elevated GH levels indicates a peripheral insensitivity to the action of GH. One possible molecular mechanism is a reduced density of GH receptors in GH target organs. In humans, the circulating high affinity GH binding protein (GHBP) is thought to reflect GH receptor expression, because it is derived from the extra-cellular domain of the GH receptor by proteolytic cleavage. We, therefore, analyzed serum GHBP levels by ligand-mediated immunofunctional assay in 126 children with CRF compared to reference values obtained by analysis of 773 healthy children. In 77% of CRF patients, serum GHBP concentrations were below the mean for age- and gender-matched controls. The decrease in serum GHBP levels was related to the degree of renal dysfunction. In advanced CRF (glomerular filtration rate, < 35 mL/min.1.73 m2), mean age- and gender-adjusted GHBP levels were -1.40 +/- 0.18 SD score; 36% of patients had GHBP levels below the normal range (< -2 SD score). Children with end-stage renal disease (n = 26) had the lowest GHBP levels (-2.25 +/- 0.22 SD score). Multiple linear regression analysis revealed that body mass index, rather than glomerular filtration rate, is the prevailing determinant of serum GHBP levels in CRF. GHBP levels correlated with both the spontaneous growth rate ( r = 0.44; P < 0.0001) and the growth response to GH therapy (r = 0.48; P < 0.005), indicating decreased sensitivity to both endogenous and exogenous GH. Subcutaneous GH therapy did not consistently affect serum GHBP levels after 3 months of treatment. It is suggested that low GHBP levels in children with CRF represent a quantitative tissue GH receptor deficiency as one of the molecular mechanisms of GH insensitivity.
BACKGROUND: Since previous studies suggest the emergency department (ED) misdiagnosis rate of heart failure is 10-20% we sought to describe the characteristics of ED patients misdiagnosed as non-decompensated heart failure in the ED. METHODS: We analyzed a prospective convenience sample of 439 patients at 4 emergency departments who presented with signs or symptoms of decompensated heart failure. Patients with a cardiology criterion standard diagnosis of decompensated heart failure and an ED diagnosis of decompensated heart failure were compared to patients with a criterion standard of decompensated heart failure but no ED diagnosis of decompensated heart failure. Two senior cardiology fellows retrospectively determined the patient's heart failure status during their acute ED presentation. The Mann-Whitney u-test for two groups, the Kruskall-Wallis test for multiple groups, or Chi-square tests, were used as appropriate. RESULTS: There were 173 (39.4%) patients with a criterion standard diagnosis of decompensated heart failure. Among those with this criterion standard diagnosis of decompensated heart failure, discordant patients without an ED diagnosis of decompensated heart failure (n = 58) were more likely to have a history of COPD (p = 0.017), less likely to have a previous history of heart failure (p = 0.014), and less likely to have an elevated b-type natriuretic peptide (BNP) level (median 518 vs 764 pg/ml; p = 0.038) than those who were given a concordant ED diagnosis of decompensated heart failure. BNP levels were higher in those with a criterion standard diagnosis of decompensated heart failure than in those without a criterion standard diagnosis (median 657 vs 62.7 pg/ml). However, 34.6% of patients with decompensated heart failure had BNP levels in the normal (<100 pg/ml; 6.1%) or indeterminate range (100-500 pg/ml; 28.5%). CONCLUSION: We found the ED diagnoses of decompensated heart failure to be discordant with the criterion standard in 14.3% of patients, the vast majority of which were due to a failure to diagnose heart failure when it was present. Patients with a previous history of COPD, without a previous history of heart failure and with lower BNP levels were more likely to have an ED misdiagnosis of non-decompensated heart failure. Readily available, accurate, objective ED tests are needed to improve the early diagnosis of decompensated heart failure in ED patients.
OBJECTIVE: To evaluate the association between admission serum concentrations of the actin-scavenger, Gc-globulin, and the subsequent development of multiple organ failure in patients with fulminant hepatic failure. DESIGN: Retrospective study. SETTING: A hepatologic intensive care unit. PATIENTS: Seventy-nine patients with hepatic encephalopathy grade 3 or 4. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Serum admission concentrations of both total and nonactin-complexed (free) Gc-globulin were determined. The development of cardiovascular failure, renal failure, pulmonary failure, intracranial hypertension, and infections were recorded in each patient. Both total and free Gc-globulin values were significantly lower in the patients, compared with normal controls. The Gc-globulin values were significantly reduced in patients who subsequently developed cardiovascular failure (p < .01), intracranial hypertension (p < .001), and infections (p < .001), compared with those patients who did not. No differences were found between patients with and without pulmonary or renal failure. Patients with total Gc-globulin values in the lowest quintile had on average 2.6 organ failures, whereas patients with Gc-globulin concentrations in the highest quintile had 0.9 organ failures. The corresponding figures for the lowest and highest quintiles of free Gc-globulin were 3.0 and 1.1 organ failures, respectively. Both total and free Gc-globulin were inversely correlated to the number of organ failures (p < .005 in both cases). Patients with multiple organ failure (> or = 2 organ failures) had significantly reduced Gc-globulin values compared with patients without multiple organ failure (p < .0001). CONCLUSIONS: In patients with fulminant hepatic failure, the lowest admission Gc-globulin concentrations were associated with the subsequent development of cardiovascular failure, intracranial hypertension, and infections. Lack of Gc-globulin correlated significantly with the development of multiple organ failure and may be pathogenetically involved in this condition.
