Clinical aspects of 2009 pandemic influenza A (H1N1) virus infection in Austria.

PURPOSE: To describe the clinical features, risk factors for severe disease and effectiveness of oseltamivir in patients with 2009 pandemic influenza A (H1N1) virus infection. METHODS: In a prospective, cross-sectional, multicentre study, data on 540 patients with confirmed 2009 H1N1 infection from seven Austrian hospitals were collected using a standardised online case-history form. RESULTS: The median age of the patients was 19.3 years (range 26 days-90.8 years); point-of-care testing yielded false-negative results in 60.2% of the 176 cases tested. The most common symptoms were fever, cough, fatigue and headache. Overall, 343 patients (63.5%) were hospitalised, 49 (9.1%) were admitted to an intensive care unit (ICU) and 14 (4.1%) died. Case fatality rates were highest (9.1%) in those aged 65 years or older. Factors significantly associated with a higher risk for ICU admission included age, neurological disease, adipositas, and both interstitial pathology and lobular pathology on chest X-ray. No association with pregnancy, malignancy or immunosuppressive therapy was detected. Antiviral treatment significantly reduced the duration of fever by 0.66 days and lowered the risk of ICU admission, but had no significant benefit on survival. CONCLUSIONS: During the 2009 H1N1 influenza pandemic, elderly or obese patients and those with neurological disease had an increased risk for severe H1N1 infection in Austria. Pregnancy was not associated with a higher risk for severe disease in the later phase of the 2009 H1N1 pandemic. Antiviral treatment provided a minimal effect on the symptoms of influenza but reduced the risk of admission to an ICU.

Prognosis of patients with a second relapse of acute myeloid leukemia.

Recurrence of the disease is the major problem in the treatment of acute myeloid leukemia (AML). The majority of patients who achieve a second remission will ultimately relapse. In this retrospective single-center study, we have analyzed the outcome of patients with a second relapse and tried to define the prognostic factors in intensively treated patients. Of 534 patients with AML, 62 had a second relapse. Thirty-three received further intensive chemotherapy (CT). Eighteen patients (55%) achieved a third complete remission (CR). The early death (ED) rate was only 9%. The overall survival (OS) of treated vs untreated patients was 6.9 vs 1.3 months, respectively (P = 0.01). The major selection criteria for a third CT were a favourable (t(15;17),t(8;21),inv(16)) or normal karyotype, long (>11 months) second CR (P < or = 0.005) and no previous bone marrow transplantation (BMT)(P < 0.01). Favorable or normal karyotype, second CR >11 months, as well as no previous BMT (P < 0.01) were associated with the achievement of a third CR. Favorable (P < 0.005) or normal karyotype (P < 0.01), as well as a second CR >11 months (P < 0.005) were associated with prolonged survival after CT. The median OS for patients receiving CT with favorable or normal cytogenetics, a second CR > 11 months, but no previous BMT was 26.5 months. Five patients with favorable or normal karyotype achieved a fourth or fifth remission. We conclude that intensive CT is associated with a survival benefit and good quality of life if patients are properly selected.

Influence of prothrombin complex concentrates on plasma coagulation in critically ill patients.

OBJECTIVE: To evaluate thrombogenicity of prothrombin complex concentrates (PCCs) in critically ill patients. DESIGN: Prospective clinical study. SETTING: Medical intensive care unit at a university hospital. PATIENTS: 16 consecutive patients suffering from acquired deficiencies of coagulation factors and with either overt bleeding from any site or a planned invasive procedure. INTERVENTIONS: 2000 factor IX units of PCCs intravenously. MEASUREMENTS AND RESULTS: Prothrombin time (PT), activated partial prothrombin time, fibrinogen, platelet count, plasma levels of coagulation factors II, V, VII, VIII, IX, X, antithrombin, protein C, thrombin-antithrombin complex (TAT), prothrombin fragment F(1+2), and the fibrin degradation product D-dimer were measured prior to and 1, 3, and 24 h after administration of PCCs. PT as well as coagulation factors II, VII, IX, and X, TAT, and F(1+2) showed a significant increase after administration of PCCs. All other parameters remained unchanged. CONCLUSIONS: Administration of PCCs induces thrombin generation. No evidence for induction of disseminated intravascular coagulation in biochemical terms could be found. When rapid correction of acquired coagulation factor disturbances is warranted, the use of PCCs seems reasonable, but the elevated risk of intravascular thrombus formation should be kept in mind.

Influence of pentoxifylline on cytokine levels and inflammatory parameters in septic shock.

OBJECTIVE: To evaluate the influence of pentoxifylline (PTX), a phosphodiesterase inhibitor, on cytokines and inflammatory proteins in patients suffering from septic shock. DESIGN: Prospective study comparing a therapy group to a matched control group. SETTING: Medical intensive care unit at a university hospital. PATIENTS: Twenty four patients fulfilling the criteria of septic shock were included in this study. Twelve patients received PTX (therapy group) and 12 patients matched for diagnosis, age and gender served as the control group. INTERVENTIONS: Pentoxifylline at 1 mg/kg per hour over 24 h in the therapy group. MEASUREMENTS AND RESULTS: Cytokine levels [tumor necrosis factor-alpha (TNF)], soluble TNF receptor [TNF-R], and interleukin-6 [IL-6] and inflammatory proteins [C-reactive protein, alpha-1-antitrypsin (AAT), fibronectin, and haptoglobin], as well as hemodynamic parameters and the APACHE III score were evaluated before initiation of therapy and 24 h-later. After 24 h, TNF levels were significantly lower in the therapy group (p = 0.013), while IL-6 levels were significantly higher in the therapy group (p = 0.030). Within the 24 h TNF declined significantly in the therapy group (p = 0.006), while IL-6 showed a significant increase (p = 0.043). AAT and the APACHE III score tended to differ significantly after 24 h between the groups [AAT levels higher in the therapy group (p = 0.05), APACHE III score lower (p = 0.05)]. In the therapy group, the systemic vascular resistance index was significantly higher after 24 h (p = 0.0026) whereas the cardiac index declined (p = 0.035). CONCLUSIONS: PTX does influence TNF levels in septic shock patients. Nevertheless, inhibiting a single mediator in severe septic shock cannot stop the inflammatory overreaction.

Serum procalcitonin levels in severe Plasmodium falciparum malaria.

Levels of procalcitonin (ProCT) have been found to be elevated in individuals with severe bacterial infections such as sepsis and peritonitis, and this correlates well with the severity of the disease. Recently, increased levels have been described in melioidosis and Plasmodium falciparum malaria. In this study ProCT levels were measured in 27 Thai patients with complicated malaria before and during/after treatment with artesunate and mefloquine. Initial parasite counts averaged 290,680/microl (range = 533-1,147,040). On admission, ProCT levels were elevated in all but one patient (median = 40 ng/ml, range = 0.04-662, normal values < 0.5 ng/ml). With treatment, levels decreased to 1.3 ng/ml (range = 0.01-6.5). Nitrite/nitrate levels in patients were higher than in controls throughout the study. The ProCT levels correlated with initial parasite density (P < 0.05), which is a marker of disease severity, and with nitrite/nitrate levels (P < 0.05). Based on the changes of ProCT levels over the course of the disease a possible role in the acute-phase reaction seems likely.

Decrease of circulating hematopoietic progenitor cells During interleukin-2 treatment is associated with an increase of vascular cell adhesion molecule-1, a critical molecule for progenitor cell adhesion.

Administration of interleukin-2 (IL-2) to cancer patients has been shown to transiently decrease the number of circulating hematopoietic progenitor cells, but the mechanism of this phenomenon is unknown. Recently, the interaction of vascular adhesion molecule-1 (VCAM-1) with leukocyte very late antigen-4 (VLA-4) has been demonstrated to play a crucial role in the adhesion of progenitor cells to bone marrow stromal elements. Cytokine induced upregulation of VCAM-1 leads to increased binding of progenitor cells to stromal cells in vitro, and inhibition of this interaction by monoclonal antibodies is associated with marked progenitor cell mobilisation in vivo. In the present study we serially determined peripheral blood progenitor cell numbers during IL-2 treatment (10 courses) in 6 cancer patients and determined in parallel levels of soluble VCAM-1 as a surrogate marker for the in vivo activation of this molecule. Our data indicate that continuous intravenous administration of IL-2 for 5 days leads to a marked decrease of circulating progenitor cells associated with a substantial increase of circulating VCAM-1. Circulating myeloid progenitor cells (CFU-GM) dropped from a mean value of 167 +/- 187 / ml pre IL-2 to 16 +/- 15 / ml on day 3 (p < 0.01). Similarily, mean erythroid progenitors (BFU-E) decreased from 282 +/- 204 / ml before IL-2 administration to 86 +/- 61 / ml on day 3 (p < 0.005). In contrast, soluble VCAM-1 rose from a mean value of 1814 +/- 451 ng/ml before to 4607 +/- 736 ng/ml at the end of IL-2 therapy (p < 0.0001). Sera from IL-2 treated patients did not inhibit hematopoietic colony formation from normal bone marrow. These results suggest redistribution and increased adhesion of progenitor cells to stromal and/or endothelial elements during IL-2 via the VCAM-1/VLA-4 interaction as a possible mechanism for the decrease of circulating progenitor cells during IL-2 therapy.

Contamination of central venous catheters in immunocompromised patients: a comparison between two different types of central venous catheters.

Catheters impregnated with silver have been proposed as a means of reducing catheter-related infection. We therefore performed a prospective randomized study to compare a new silver-impregnated central venous catheter (CVC) with a commercially available CVC in a cohort of immunocompromised patients. We studied 157 patients of whom 97 could be analysed. The median indwelling time in the study group (SC) was 10.5 days and 11 days in the control group (CC). The incidence of contamination in the SC group was 15.6 vs 24.6 in the CC group referring to 1000 catheter days. In both groups, we found 6% of catheter-related infections according to the definitions of a published scoring system. The differences between the two groups were not significant. We conclude that the SC decrease the incidence of catheter contamination and may have a positive effect on the reduction of CVC-related infections.

Serum concentrations of granulocyte-colony stimulating factor in complicated Plasmodium falciparum malaria.

Involvement of neutrophils in the control of blood parasites in malaria has been reported. Both, mononuclear phagocytes and neutrophils are known to be stimulated by cytokines such as TNF-alpha in order to augment the defence potency against the parasites. Previously, it has been shown that serum-G-CSF concentrations are increased in patients with bacterial sepsis. In vitro studies have shown that P. falciparum - infected erythrocytes induce the release of G-CSF by several cells such as endothelial cells and monocytes, however, nothing is known about G-CSF serum concentrations during the clinical course of severe P. falciparum malaria. Thus, it was the aim of the present study to investigate the time course for G-CSF serum concentrations in patients with complicated P. falciparum malaria, and to correlate these values with other mediators of inflammation and hematopoesis. Twenty-six patients suffering from complicated P. falciparum malaria were included in the study, and 20, age and sex matched, healthy volunteers were used as the negative control group. Serum samples for determination of G-CSF were taken on day 0, 7 and 14, and measured by ELISA. We found significantly increased serum concentrations of G-CSF in patients with complicated P. falciparum malaria on day 0, values decreasing to within the normal range by day 7. A significant correlation was found between G-CSF (d0) and procalcitonin, the parasite count, erythropoietin and macrophage inflammatory protein, however no correlation could be shown for the neutrophil count. In conclusion, on the day of hospital admission, elevated serum concentrations of G-CSF were detected in patients with complicated P. falciparum malaria, which might indicate a role of G-CSF in the acute defence mechanism against the parasites.

Relation of pro- and anti-inflammatory cytokines and the production of nitric oxide in patients receiving high-dose immunotherapy with interleukin-2.

Immunotherapy with intravenous recombinant human interleukin-2 (rh IL-2) may be accompanied by hypotension and the emergence of capillary leak syndrome. Nitric oxide (NO) is supposed to be responsible for both side effects. The aim of the current investigation was to elucidate the relationship between pro- and anti-inflammatory cytokines and the production of NO in eight tumor patients receiving intravenous rh IL-2 continuously over a time period of 120 hours. Markers of systemic inflammation, as well as nitrate plasma levels, were consecutively determined. Significant changes in the levels of pro-inflammatory cytokines IL-6 and IL-8 were observed (p < 0.05). In contrast to the anti-inflammatory cytokine IL-10, which did not increase significantly, the serum concentrations of the soluble tumor necrosis factor receptors (sTNFr) I and II rose continuously and significantly during the observation period (p < 0.05). In parallel, a significant rise in nitrate plasma levels was observed (p < 0.05). Moreover, there were highly significant correlations between nitrate and IL-6 serum levels (p < 0.05), nitrate and sTNFr-I (p < 0.05), nitrate and sTNFr-II (p < 0.05), and between IL-6 and IL-10 (p < 0.05), respectively. We conclude that immunotherapy with IL-2 promotes a pro-inflammatory state, parallelled by an increased production of nitric oxide. Although anti-inflammatory responses accompany this process, they are not able to diminish the production of nitric oxide.

A case of visceral leishmaniasis in Austria.

We report a patient aged 41 years with fever of unknown origin. Notable aspects of his travel history were a trip to the Philippines and a sailing trip around Sicily. The patient presented with fever up to 40 degrees C since 4 weeks, weakness, headache, hepatosplenomegaly and night sweat. No specific cause could be found. Based on clinical findings tuberculosis was suspected and empirical tuberculostatic treatment was started. However, during the following 6 weeks the patient's condition deteriorated. A bone marrow biopsy performed to exclude a haematological malignancy revealed Leishmania sp. in macrophages. This histological diagnosis was confirmed retrospectively by re-examination of a previously performed liver biopsy and by an increased anti-leishmania serum antibody titer of 1:1280. The patient was treated with sodium stibogluconate (pentostam, 850 mg) for 30 days and recovered slowly.

Renal tolerability of four different once-daily dose regimen of netilmicin in critical care patients.

A prospective, randomized trial was conducted in a medical intensive care unit to assess safety and tolerability of four different dose regimens of intravenous netilmicin given once daily in the treatment of febrile episodes in critically ill patients. Eighty patients with febrile episodes during their stay in the intensive care unit were included in the study. The patients were randomized into four groups: Group 1 received a single daily dose of netilmicin based upon weight, age and renal function according to a dosage nomogram [13] (mean dose 298 +/- 29 mg, median 300 mg, range 250-350 mg), group 2 received 150% of this standard dose (mean 418 +/- 45 mg, median 400 mg, range 350-500 mg), group 3 200% (mean 525 +/- 41 mg, median 500 mg, range 400-550 mg) and group 4 250% (mean 710 +/- 39 mg, median 650 mg, range 600-750 mg). Duration of treatment was six days. Positive cultures were obtained in 29 patients. Serum creatinine and creatinine clearance, as well as netilmicin trough levels and levels of alpha 1-microglobulin showed no significant difference between the groups before, during, and after therapy. Our results indicate that with once daily dosing even high doses of netilmicin are well tolerated in patients with a creatinine clearance of > 70 ml/min before therapy. Necessary precautions include monitoring of drug trough levels (< 1 mg/L) and maintenance of adequate volume status.

Placement of a pulmonary artery catheter via a previously unrecognized persistent left superior vena cava.

This case report describes a patient with persistent left superior vena cava (LSVC) as discovered by difficult placement of a pulmonary artery catheter via the left subclavian vein. After positioning in wedge position, chest x-ray showed a catheter route suggestive of persistent LSVC. Since this abnormality may yield potential clinical complications, this possibility should be considered in every difficult central venous access.

Serum nitrate concentrations in patients with peripheral arterial occlusive disease.

BACKGROUND: Nitric oxide (NO), an endogenous product of L-arginine oxidation, seems to account for the vasodilatatory effect of the endothelium-derived relaxing factor. It was the aim of the present study to measure serum nitrate concentrations, the degradation product of nitric oxide in patients with peripheral arterial occlusive disease (PAOD). PATIENTS AND METHODS: 20 patients with PAOD in Fontaine stage IIb, 10 patients in stage III and IV respectively were included in the study. Serum samples for determination of nitrate were taken at admission after fasting overnight. Nitrate concentrations were determined using a recently developed high performance liquid chromatography which allows direct measurement of nitrate. The control group comprised 14 age and risk factor matched volunteers. RESULTS: We found significantly increased nitrate concentrations in patients with PAOD compared to the control group [stage IIb: 6.65 +/- 1.58 mumol/l; stage III: 6.94 +/- 1.85 mumol/l, stage IV: 7.05 +/- 1.16 mumol/l; control: 4.41 +/- 1.24 mumol/l], however no significance was calculated within the different PAOD groups. There was no association of either diabetes mellitus, hypertension and smoking behaviour with increased nitrate levels. CONCLUSION: These data might indicate that NO might be involved in adaptive vasodilatation already in the early phase of the disease. The source of nitrate in PAOD patients, however, remains unclear.

Prostaglandin E(1) does not influence plasmatic coagulation, hepatic synthesis, or postoperative blood loss in patients after coronary-artery bypass grafting.

STUDY OBJECTIVE: To assess whether postoperatively administered prostaglandin E1 (PGE1) might prevent bleeding in patients after coronary artery bypass grafting (CABG). DESIGN: Prospective, randomized, placebo-controlled trial. SETTING: University-affiliated hospital. PATIENTS: 49 patients scheduled for elective CABG surgery. INTERVENTIONS: The PGE1 group received intravenous PGE(1) up to 15 ng/kg/min for 72 hours after surgery, whereas the placebo group received isotonic saline for the same time period. MEASUREMENTS AND MAIN RESULTS: Nine patients (4 in the PGE1 group vs. 5 in the placebo group) had to be excluded because of hemodynamic instability, and 1 in the placebo group because of gastric bleeding. In the remaining 39 patients (20 vs. 19), no significant differences with regard to hemoglobin levels or platelet count could be observed. There was no significant difference between the groups concerning the amount of packed red blood cells, platelet concentrates, or fresh frozen plasma transfused. No significant differences could be observed regarding laboratory markers of coagulation activation or hepatic synthesis either. CONCLUSIONS: PGE1 did not prevent coagulation disturbances and blood loss when administered postoperatively in patients undergoing CABG. The absence of these expected effects might be explained by the concomitant administration of acetylsalicylic acid, whose antiaggregatory acivity seems to exceed the effects of PGE1.

Copeptin, a fragment of the vasopressin precursor, as a novel predictor of outcome in heart failure.

BACKGROUND: Natriuretic peptides, particularly brain natriuretic peptide (BNP), are elevated in heart failure and therefore considered to be excellent predictors of outcome. Vasopressin is also known to be related to the severity of heart disease. Copeptin--an inactive fragment of the vasopressin precursor--has not been previously investigated in the context of heart failure. MATERIALS AND METHODS: We prospectively studied 268 patients with advanced heart failure after they had been discharged from the hospital. We investigated the ability of BNP and copeptin to predict death, re-hospitalization due to heart failure, and a combination of the two endpoints. RESULTS: Over a mean follow-up period of 15.8 months (up to 24 months), 83 patients died, 122 patients experienced worsening of heart failure, and 145 patients achieved the combined endpoint. Univariate predictors of death were copeptin, BNP, age and impaired kidney function. In multivariate analysis, copeptin (chi(2) = 16, P < 0.0001) and age (chi(2) = 4, P < 0.05) were independent predictors. Univariate predictors of re-hospitalization due to heart failure were copeptin, BNP, age and impaired kidney function. Furthermore, in multivariate analysis BNP (chi(2) = 18, P < 0.0001), age (chi(2) = 11.8, P < 0.001) and copeptin (chi(2) = 4.2, P < 0.05) were found to be independent predictors. CONCLUSION: Our study is the first to show that copeptin is an excellent predictor of outcome in advanced heart failure patients. Its value is superior to that of BNP in predicting death and a combined endpoint, although BNP is still suitable for predicting chronic heart failure (CHF) re-hospitalization. Our data imply that vasopressin antagonism might be a new target to improve outcome in this population.

Measurement of serum nitrite/nitrate concentrations using high-performance liquid chromatography.

Previous studies have reported increased serum concentrations of nitrite/nitrate - the degradation products of nitric oxide - in Plasmodium vivax malaria and uncomplicated Plasmodium falciparum malaria. In all these studies, however, nitrite/nitrate has been measured spectrometrically using Griess reagent which carries major disadvantages in the determination of serum nitrite/nitrate. The method does not allow an exact differentiation of nitrite and biogenic amines that are physiologically present in plasma. In the present study we introduce high-performance liquid chromatography as a new, accurate and cost effective method for determination of serum nitrite/nitrate levels. Significantly increased nitrate concentrations were found in malaria patients and serum values remained above normal levels for at least 21 days. It could be shown that our HPLC method is a sensitive and cost-effective method for direct determination of nitrite/nitrate in serum samples, which is not influenced by the presence of biogenic amines.

Homocysteine and laminin are not prognostic markers in patients with septic inflammatory response syndrome.

The aim of this study was to measure plasma homocysteine and laminin concentrations in patients with nonbacteremic systemic inflammatory response syndrome (SIRS) and to compare them with those of a healthy control group. Concerning laminin, significant increased concentrations could be observed in the SIRS group compared to the control group, but for homocysteine, no significance could be observed. In summary, homocysteine and laminin levels are not useful in the prediction of a patient's outcome.

The assessment of four different methods to verify tracheal tube placement in the critical care setting.

UNLABELLED: One of the most serious complications of conventional endotracheal intubation is unidentified placement of the tube in the esophagus. The aim of our study was to evaluate four different methods for immediate detection of the tube position: auscultation, capnographic determination of ETCO2, esophageal detection method (EDM) using a self-inflating bulb, and the transillumination method using a lighted stylet (Trachlight; Laerdal, Armonk, NY). Thirty-eight endotracheally intubated patients admitted to our medical intensive care unit were enrolled in the study. A second identical tube was inserted into the esophagus under laryngoscopic control. The endotracheal tube was then disconnected from the ventilator. Two blinded examiners, one experienced, the other inexperienced, determined the tube position within 30 s using one of the four methods. The order of the tubes tested and the methods used were randomized. In 130 of 152 examinations, both examiners correctly diagnosed the position of the tube. The wrong result was obtained by both examiners 4 times; only the experienced examiner was wrong 4 times, and only the inexperienced examiner was wrong 14 times. Using ETCO2, both examiners were correct in all cases. Auscultation showed an obvious relation to the examiner's experience: the experienced examiner was correct in all cases, the inexperienced examiner was correct in only 68% of cases. Using the self-inflating bulb, there were two wrong results of the experienced examiner and one wrong result of the inexperienced examiner. The transillumination technique was associated with a high error rate by both examiners (16% and 13%, respectively). Comparing all four methods showed that capnography is superior to auscultation (P = 0.0005) and to the Trachlight detection method (P = 0.0078). EDM was not statistically superior to auscultation and transillumination. Capnography was the most reliable method for rapid evaluation of tube position, followed by EDM, whereas auscultation and Trachlight did not seem to be of comparable value. Experience was a determining factor for auscultation. IMPLICATIONS: To prevent unidentified esophageal intubation, a serious complication in the critical care setting, four methods for detecting tube position were tested by two examiners (one experienced, the other inexperienced) in endotracheally intubated patients after insertion of a second tube into the esophagus.

Outcome and prognostic factors in critically ill cancer patients admitted to the intensive care unit.

OBJECTIVE: To assess survival in cancer patients admitted to an intensive care unit (ICU) with respect to the nature of malignancy, cause of ICU admittance, and course during ICU stay as well as to evaluate the prognostic value of the Acute Physiology and Chronic Health Evaluation (APACHE) III score. DESIGN: Retrospective cohort study. SETTING: ICU at a university cancer referral center. PATIENTS: A total of 414 cancer patients admitted to the ICU during a period of 66 months. INTERVENTIONS: None. MEASUREMENTS: Charts of the patients were analyzed with respect to underlying disease, cause of admission, APACHE III score, need and duration of mechanical ventilation, neutropenia and development of septic shock, as well as ICU survival and survival after discharge. Mortality data were compared with two control groups: 1362 patients admitted to our ICU suffering from diseases other than cancer and 2,776 cancer patients not admitted to the ICU. MAIN RESULTS: ICU survival was 53%, and 1-yr survival was 23%. The 1-yr mortality rate was significantly lower in both control groups. Patients admitted after bone marrow transplantation had the highest mortality. In a multivariate analysis, prognosis was negatively influenced by respiratory insufficiency, the need of mechanical ventilation, and development of septic shock during the ICU stay. Admission after cardiopulmonary resuscitation yielded high ICU mortality but a relatively good long-term prognosis. Admission after surgery and as a result of acute hemorrhage was associated with a good prognosis. Age, neutropenia, and underlying disease did not influence outcome significantly. Admission APACHE III scores were significantly higher in nonsurvivors but failed to predict individual outcome satisfactorily. All patients with APACHE III scores of >80 died at the ICU. CONCLUSION: A combination of factors must be taken into account to estimate a critically ill cancer patient's prognosis in the ICU. The APACHE III scoring system alone should not be used to make decisions about therapy prolongation. Admission to the ICU worsens the prognosis of a cancer patient substantially; however, as ICU mortality is 47%, comparable with severely ill noncancer patients, general reluctance to admit cancer patients to an ICU does not seem to be justified.
