Intensive care unit (ICU) admission is associated with high mortality in allogeneic hematopoietic stem cell transplant (HSCT) recipients. Whether mortality has decreased recently is unknown. The 497 adult allogeneic HSCT recipients admitted to three ICUs between 1997 and 2011 were evaluated retrospectively. Two hundred and nine patients admitted between 1997 and 2003 were compared with the 288 patients admitted from 2004 to 2011. Factors associated with 90-day mortality were identified. The recent cohort was characterized by older age, lower conditioning intensity, and greater use of peripheral blood or unrelated-donor graft. In the recent cohort, ICU was used more often for patients in hematological remission (67% vs 44%; P<0.0001) and without GVHD (73% vs 48%; P<0.0001) or invasive fungal infection (85% vs 73%; P=0.0003) despite a stable admission rate (21.7%). These changes were associated with significantly better 90-day survival (49% vs 31%). Independent predictors of hospital mortality were GVHD, mechanical ventilation (MV) and renal replacement therapy (RRT). Among patients who required MV or RRT, survival was 29% and 18%, respectively, but dropped to 18% and 6% in those with GVHD. The use of ICU admission has changed and translated into improved survival, but advanced life support in patients with GVHD usually provides no benefits.

BACKGROUND: Data are scarce about ICU patients with malignancy and severe pulmonary embolism. Here, our main objective was to identify risk factors for life-threatening complications, organ failures, and death in ICU patients with severe pulmonary embolism, with special attention to the impact of malignancy. We also described the clinical features of PE in patients with and without malignancies. METHODS: Data from consecutive adults admitted to our ICU in 2002-2011 with severe pulmonary embolism were collected retrospectively. Multivariate analysis was performed to look for factors associated with death, organ failures, or life-threatening complications (major bleeding, recurrent PE, and cardiac arrest). RESULTS: Of 119 included patients (42 [35%] with bilateral pulmonary embolism), 41 had solid malignancies, 27 hematological malignancies, and 51 no malignancies. The most common symptoms were syncope (40%) and hemoptysis (18%) in patients with solid and hematological malignancies, respectively. Life-threatening complications occurred in 23 (19%) patients; risk factors were obesity (OR, 13.22; 1.93-90.70), disseminated intravascular coagulation/ischemic hepatitis (OR, 27.06; 5.14-142.46), fluid load ≥1000 mL/24 h (OR, 6.42; 1.60-25.76), and solid malignancy (OR, 5.45; 1.15-25.89). Inhospital mortality was 27/119 (23%) and respiratory or circulatory failure developed in 36 (30%) patients. Risk factors for these adverse outcomes were older age (OR, 1.04/year; 1.01-1.07), higher oxygen flow rate (OR, 1.28/L; 1.13-1.45); and renal failure (OR, 8.08; 2.50-26.11); whereas chest pain was protective (OR, 0.13; 0.04-0.48). CONCLUSION: In this study, solid malignancy was a risk factor for life-threatening complications but not for death.

The use of steroids is not required in myeloid malignancies and remains controversial in patients with acute lung injury (ALI) or acute respiratory distress syndrome (ARDS). We sought to evaluate dexamethasone in patients with ALI/ARDS caused by acute monocytic leukaemia (AML FAB-M5) via either leukostasis or leukaemic infiltration. Dexamethasone (10 mg every 6 h until neutropenia) was added to chemotherapy and intensive care unit (ICU) management in 20 consecutive patients between 2005 and 2008, whose data were compared with those from 20 historical controls (1994-2002). ICU mortality was the primary criterion. We also compared respiratory deterioration rates, need for ventilation and nosocomial infections. 17 (85%) patients had hyperleukocytosis, 19 (95%) had leukaemic masses, and all 20 had severe pancytopenia. All patients presented with respiratory symptoms and pulmonary infiltrates prior to AML FAB-M5 diagnosis. Compared with historical controls, dexamethasone-treated patients had a significantly lower ICU mortality rate (20% versus 50%; p = 0.04) and a trend for less respiratory deterioration (50% versus 80%; p = 0.07). There were no significant increases in the rates of infections with dexamethasone. In conclusion, in patients with ALI/ARDS related to AML FAB-M5, adding dexamethasone to conventional chemotherapy seemed effective and safe. These results warrant a controlled trial of dexamethasone versus placebo in AML FAB-M5 patients with noninfectious pulmonary infiltrates.

PURPOSE: Human herpesvirus 6 (HHV6) is an emerging cause of interstitial pneumonia in immunocompromised hosts. However, the clinical significance of a positive PCR test for HHV6 in respiratory samples from patients with hematological malignancies remains unclear. METHODS: We retrospectively studied the features and outcomes of 29 critically ill hematology patients with acute respiratory failure and lung pulmonary infiltrates visible on a chest radiograph, who tested positive for a qualitative PCR for HHV6 in bronchoalveolar lavage fluid. RESULTS: Of the 29 patients, 18 (62%) were stem cell transplant recipients and 11 (38%) had received chemotherapy. All patients had a fever. Clinical manifestations consistent with extra-pulmonary HHV6 disease were noted in 17 (59%) patients. One or more co-pathogens were found in 25 (86%) patients. The four remaining patients diagnosed with HHV6 pneumonia and subsequently recovered with foscarnet therapy. Antiviral therapy was also given to seven patients with co-infections, of whom two ultimately died. CONCLUSIONS: In most cases, HHV6 recovered from BAL fluid is a co-pathogen whose clinical relevance remains undetermined. However, in some cases, HHV6 is the only pathogen, along with disseminated systemic viral disease, and the patient is likely to benefit from foscarnet therapy.

Human immunodeficiency virus (HIV) infection is a risk factor for thrombotic microangiopathy (TMA). We sought whether a severe deficiency in ADAMTS13, the enzyme specifically involved in the cleavage of von Willebrand factor, was associated with specific presenting features and outcome in HIV-associated TMA. In this prospective, multicentre, case-control study, 29 patients of 236 in the French Network on TMA had an HIV-associated TMA. Seventeen patients with severe ADAMTS13 deficiency (ADAMTS13 <5% HIV(+) group) were compared to 12 patients with a detectable ADAMTS13 activity (ADAMTS13 >or=5% HIV(+) group). HIV(+) patients were also compared to 62 patients with idiopathic TMA, either with (45 patients, ADAMTS13 <5% idiopathic group) or without (17 patients, ADAMTS13 >or=5% idiopathic group) severe ADAMTS13 deficiency. ADAMTS13 <5% HIV(+) patients had less AIDS-related complications than ADAMTS13 >or=5% HIV(+) patients (23.5% versus 91.6%, respectively, P = 0.0005) and their median CD4(+) T cell count was higher (P = 0.05). TMA-associated death rate was higher in ADAMTS13 >or=5% HIV(+) patients than in ADAMTS13 <5% HIV(+) patients (50% versus 11.7%, respectively, P = 0.04). In ADAMTS13 <5% patients, TMA-associated death rate was comparable between HIV(+) and idiopathic patients (15.5% in idiopathic patients, P-value was non-significant). By contrast, TMA-associated death rate in ADAMTS13 >or=5% HIV(+) patients was higher than in idiopathic patients (11.7% in idiopathic patients, P = 0.04). In conclusion, HIV-associated TMA with severe ADAMTS13 deficiency have less AIDS-related complications and a higher CD4(+) T cell count. TMA prognosis is better and comparable to this of idiopathic forms.

INTRODUCTION: About 15% of patients with haematological malignancy develop acute respiratory failure (ARF), necessitating admission to intensive care where their mortality is of the order of 50%. STATE OF THE ART: The prognosis of these patients is not determined by the pathological characteristics of the malignancy but by the cause of the acute respiratory failure. In effect, the need to resort to mechanical ventilation in the presence of dysfunction of other organs dominates the prognosis. Even if the use of non-invasive ventilation in these patients has reduced the need for intubation and reduced the mortality, its prolonged use in the most severely affected patients prevents the optimal diagnostic and therapeutic management. PERSPECTIVES: Fibreoptic bronchoscopy with broncho-alveolar lavage (BAL) is considered the cornerstone of aetiological diagnosis but its diagnostic effectiveness is poor, at best 50%, and this has led to increasing interest in high resolution CT scanning and regularly reawakens a transitory enthusiasm for surgical lung biopsy. Furthermore, in hypoxaemic patients, fibreoptic bronchoscopy with BAL may be the origin of the resort to mechanical ventilation, and thus increased mortality. The place of recently developed non-invasive tools is under evaluation. In effect, though the individual performance of diagnostic molecular techniques on sputum, blood, urine or naso- pharyngeal secretions has been established, the combination of these tools as an alternative to BAL has not yet been reported. CONCLUSION: This review deals with acute respiratory failure in patients with haematological malignancy. It includes a review of the recent literature and considers the current controversies, in particular the risk-benefit balance of fibreoptic bronchoscopy with BAL in severely hypoxaemic patients.

High case volume is associated with improved survival in medical and surgical conditions. The present study sought to determine whether intensive care unit (ICU) case volume was associated with survival of critically ill patients with haematological malignancies and acute respiratory failure (ARF). A regional database containing data from 1,753 haematological patients with ARF admitted to 28 medical ICUs from 1997 to 2004 was used. Multivariate analysis using mixed models was performed to adjust for severity of illness and other confounding factors, including a propensity score that incorporates differences between ICUs with different case volumes. The three case volume tertiles were: low volume (<12 admissions per year), intermediate volume (12-30 admissions per year), and high volume (>30 admissions per year). In univariate analyses, ICU case volume was not associated with ICU mortality. After adjusting for prognostic factors for ICU mortality and the propensity score, patients in high-volume ICUs had lower mortality than other patients. A case volume increase of one admission per year led to a significant mortality reduction with an odds ratio of 0.98 (95% confidence limits 0.97-0.99). Mortality was independently associated with severity of organ dysfunction. In intensive care units admitting larger numbers of critically ill haematological patients with acute respiratory failure, mortality was lower than in other intensive care units. The mechanisms of the relationship between volume and outcome among haematological patients with acute respiratory deserve additional studies.

Exacerbation of prior pulmonary involvement may occur during neutropenia recovery. Granulocyte colony-stimulating factor (G-CSF)-related pulmonary toxicity has been documented in cancer patients, and experimental models suggest a role for G-CSF in acute lung injury during neutropenia recovery. We reviewed 20 cases of noncardiac acute respiratory failure during G-CSF-induced neutropenia recovery. Half the patients had received hematopoietic stem cell transplants. All patients experienced pulmonary infiltrates during neutropenia followed by respiratory status deterioration coinciding with neutropenia recovery. Neutropenia duration was 10 (4-22) days, and time between respiratory symptoms and the first day with more than 1000 leukocytes/mm3 was 1 (-0.5 to 2) day. Of the 20 patients, 16 received invasive or noninvasive mechanical ventilation, including 14 patients with acute respiratory distress syndrome (ARDS). Five patients died, with refractory ARDS. In patients with pulmonary infiltrates during neutropenia, G-CSF-induced neutropenia recovery carries a risk of respiratory status deterioration with acute lung injury or ARDS. Clinicians must maintain a high index of suspicion for this diagnosis, which requires eliminating another cause of acute respiratory failure, G-CSF discontinuation and ICU transfer for early supportive management including diagnostic confirmation and noninvasive mechanical ventilation.

BACKGROUND: Systemic capillary leak syndrome (SCLS) is a severe disorder characterized by unexplained rapid transfer of considerable volumes of plasma from the intravascular to the extravascular compartment. For some cases of SCLS, no aetiology is evident and these cases are reported as idiopathic (ISCLS). OBJECTIVES: To describe the cutaneous findings in 3 patients with ISCLS. RESULTS: Cutaneous involvement consisted in sclerosis, livedo, purpura and photodistributed maculopapular erythematous rash. Dermal mucinosis was proven by biopsy in 1 patient. No underlying disease was diagnosed during follow-up. CONCLUSION: The above-mentioned cutaneous findings can be present during acute attacks of ISCLS. They seem specifically related to the ISCLS and not indicative of an underlying disease.

Previously, polymerase chain reaction (PCR) technology has been hampered by its inability to generate quantitative results, a drawback inherent to the high degree of amplification taking place in the reaction. Recently, PCR techniques have been described with the potential of quantifying the amount of mRNA or DNA in biological samples. In this study quantitative PCR was used to investigate the role of the EGF (epidermal growth factor) system in cancer both for measurements of mRNA concentrations and for measurements of the number of copies of specific genes. It is shown that the mRNA expression of a subset of ligands from the EGF system is increased in bladder cancer. Furthermore, measurement of the mRNA concentration gives important information such as the expression of these ligands correlated to the survival of the patients. In addition to the alterations at the mRNA level, changes also can occur at the DNA level in the EGF system. Thus, it has been demonstrated that the number of genes coding for the human epidermal growth factor receptor 2 (HER2) is increased in a number of breast tumors. It is now possible to treat breast cancer patients with a humanized antibody reacting with HER2, and the treatment is considered to be justified if the tumor displays an increased amount of HER2. For this reason there is a need for techniques suitable for HER2 measurements. A LightCycler real-time PCR method used for HER2/neu DNA quantification was evaluated and the results compared with those obtained by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH). Tumor biopsies were collected from 112 patients diagnosed with early breast cancer from January 1990 to March 1994. The samples were analyzed for HER2 DNA amplification by real-time PCR on LightCycler and by FISH and for HER2 protein expression by IHC. Inter-assay variation for HER2 measured by LightCycler was 10% (x =3.1; n=17). Amplification > or = 2 was observed in 19% of the patients. Concordance rates between real-time PCR and the other methods were 91% (IHC) and 92% (FISH). The correlation between real-time PCR and FISH was highly significant (p < 0.001). The "LightCycler-HER2/neu DNA quantification kit" produces results with a high level of reproducibility and its ease of use allows rapid screening for amplification of HER2. In this paper useful information is given on how real-time PCR compares with FISH and IHC. The data show that results obtained for amplification of HER2 by real-time PCR on the LightCycler instrument are comparable to results obtained by IHC and FISH.

There are few data on Pneumocystis carinii pneumonia (PCP) in critically ill human immunodeficiency virus (HIV)-negative patients. Improved knowledge of the presenting symptoms of and prognostic factors for PCP may help to reduce the high mortality rate associated with PCP in such patients. We retrospectively studied 39 consecutive patients with acute PCP-related respiratory failure and malignancy who were treated at 2 intensive care units (ICUs) during a 10-year period. Univariate logistic regression identified the following 8 predictors of mortality at 30 days after patient admission to the ICU (30-day mortality rate, 33%): complete remission of the malignancy (odds ratio [OR], 0.18), receipt of >1 course of antimalignancy chemotherapy (OR, 17.2), involvement of 4 lobes noted on a chest radiograph (OR, 5), >15% neutrophils in bronchoalveolar lavage [BAL] fluid specimens (OR, 6), Organ System Failure score (OR, 7.33), Simplified Acute Physiology Score II (OR, 1.12), and the need for either mechanical ventilation (OR, 63) or vasopressors (OR, 25.9). Studies are needed to determine whether aggressive monitoring and treatment of patients with >15% neutrophils in BAL fluid specimens can improve the outcome of critically ill patients with malignancy and PCP.

OBJECTIVE: To assess the prognostic value of two severity of illness scores, commonly used for critically ill patients, Simplified Acute Physiology Score (SAPS II) and Organ Dysfunctions and Infection (ODIN), in predicting mortality in febrile neutropenic patients in hematology wards. DESIGN: A 2-month prospective multicenter study. SETTING: Thirty-six hematologic and/or stem cell transplant units in France. PATIENTS: All adult patients with a first febrile neutropenic episode (polymorphonuclear cells <500/mm(3)) were included. INTERVENTIONS: SAPS II was calculated on day 1 of fever, and ODIN on days 1 and 8. The end point was the mortality rate on day 28. MEASUREMENTS AND MAIN RESULTS: Twenty-eight (6.6%) of the 421 patients included died before day 28. The mortality rate predicted by SAPS II was 23.8%, indicating a poor calibration. The SAPS II score at day 1 was greater in nonsurvivors than in survivors (44 +/- 11 vs. 38 +/- 7, p <.0001), as was the number of patients with one or more organ failures at day 1 (14 vs. 2%, p <.0001), and day 8 (42 vs. 3%, p <.0001). The pattern of change in the scores over the first 8 days differed significantly between survivors and nonsurvivors. In multivariate analysis, only ODIN on day 1 and day 8, and spontaneous neutropenia were independent predictors for death. CONCLUSIONS: SAPS II and ODIN scores are inaccurate for predicting individual outcome of febrile neutropenic patients in hematology wards. Serial measurements of these scores during the first week of hospitalization could be more accurate than a single measurement. Besides severity scores and organ failures, the type of neutropenia is at least as important in assessing the prognosis.

DESIGN: Recommendations for triage to intensive care units (ICUs) have been issued but not evaluated. SETTING: In this prospective, multicenter study, all patients granted or refused admission to 26 ICUs affiliated with the French Society for Critical Care were included during a 1-month period. Characteristics of participating ICUs and patients, circumstances of triage, and description of the triage decision with particular attention to compliance with published recommendations were recorded. RESULTS: During the study period, 1,009 patients were and 283 were not admitted to the participating ICUs. Refused patients were more likely to be older than 65 yrs (odds ratio [OR], 3.53; confidence interval [CI], 1.98-5.32) and to have a poor chronic health status (OR, 3.09; CI, 2.05-4.67). An admission diagnosis of acute respiratory or renal failure, shock, or coma was associated with admission, whereas chronic severe respiratory and heart failure or metastatic disease without hope of remission were associated with refusal (OR, 2.24; CI, 1.38-3.64). Only four (range, 0-8) of the 20 recommendations for triage to ICU were observed; a full unit and triage over the phone were associated with significantly poorer compliance with recommendations (0 [0-2] vs. 6 [2-9], p =.0003; and 1 [0-6] vs. 6 [1-9], p <.0001; respectively). CONCLUSION: Recommendations for triage to intensive care are rarely observed, particularly when the unit is full or triage is done over the phone. These recommendations may need to be redesigned to improve their practicability under real-life conditions, with special attention to phone triage and triaging to a full unit.

The aim of antibiotic prophylaxis (ABP) is to prevent or at least decrease the incidence of postoperative surgical wound infections. In 1992 and 1995, ABP was the subject of two French consensus conferences. Following these conferences, the local Antibiotics Committee of Hopital Saint-Louis has undertaken a study to evaluate and eventually improve the current practices of ABP. This study was carried out in three steps: a first survey of ABP, the writing of local ABP guidelines and a second survey of ABP after the implementation of these recommendations. Concerning all surgical wards, the first survey found 69% (N = 100/145) of ABP practice is to be inappropriate vs. 18% (N = 25/139) in the second survey. Indications, choice of drugs, selection of dosage, administration timing and treatment duration were significantly improved in the second survey. Writing and implementing local recommendations promoted a more rational use of ABP. In addition, this study allowed Saint-Louis Hospital to set up recommendations for plastic surgery; such recommendations are poorly described in the literature.

Plasma infusion (PI) and plasma exchange (PE) are the most efficient treatment of thrombotic thrombocytopenic purpura (TTP), allowing achievement of complete remission in 60 to 90% of cases. Life-threatening bleeding, related to severe thrombocytopenia, is one of the main complications of the disease. Thrombocytopenia may also preclude invasive procedures such as splenectomy, which may be required during the management of TTP. Platelet concentrates transfusions are usually thought to worsen the disease, especially if not associated with the appropriate treatment of this latter, and thus should be avoided. We report hereon 2 patients with TTP who experienced a surgical procedure i.e., a cholecystectomy for a cholecystitis, and a splenectomy for a refractory TTP. In both patients, the surgical procedure was preceded by a 60 mL/kg plasma exchange with solvent/detergent treated plasma as replacement fluid, followed by platelet transfusion, with a corrected count increment of 57.1% (Patient 1) and 69.3% (Patient 2). Using this sequential treatment, the patients did not experience any deterioration of their status. Both patients had a favorable outcome after surgery. However, until such a procedure will be validated on a larger series of patients, it should be restricted to patients presenting with a refractory life-threatening thrombocytopenia and/or requiring surgery or any kind of invasive procedure.

OBJECTIVE: Effective communication of simple, clear information to families of intensive care unit (ICU) patients is a vital component of quality care. The purpose of this study was to identify factors associated with poor comprehension by family members of the status of ICU patients. DESIGN: Prospective study. SETTING: University-affiliated medical intensive care unit. PATIENTS AND METHODS: A total of 102 patients admitted to an ICU for >2 days. INTERVENTION: The representatives of 76 patients who were visited by at least one person during their ICU stay were interviewed. RESULTS: Mean patient age was 54+/-17 yrs and mean Simplified Acute Physiology Score II at admission was 40+/-20. The representative was the spouse in 47 cases (62%). Among representatives, 25 (33%) were of foreign descent and 12 (16%) did not speak French. Mean duration of the first meeting with a physician was 10+/-6 mins. In 34 cases (54%), the representative failed to comprehend the diagnosis, prognosis, or treatment of the patient. Factors associated with poor comprehension by representatives included patient-related, family-related, and physician-related factors. Patient-related factors included age <50 yrs (p = .03), unemployment (p = .01), referral from a hematology or oncology ward (p = .006), admission for acute respiratory failure (p = .005) or coma (p = .01), and a relatively favorable prognosis (p = .04). Family-related factors were foreign descent (p = .007), no knowledge of French (p = .03), representative not the spouse (p = .03), and no healthcare professional in the family (p = .01). Physician-related factors were first meeting with representative <10 mins (p = .03) and failure to give the representative an information brochure (p = .02). Moreover, after the first meeting, caregivers accurately predicted poor comprehension by representatives (p = .03). CONCLUSIONS: Patient information is frequently not communicated effectively to family members by ICU physicians. Physicians should strive to identify patients and families who require special attention and to determine how their personal style of interrelating with family members may impair communication.
