Despite improvements in the management of cirrhotic patients admitted to the ICU and in the management of MV for the treatment of ARDS, cirrhosis remained associated with a poorer prognosis in ARDS patients. The prognosis of cirrhotic patients with ARDS appears related to extrapulmonary organ dysfunctions rather than pulmonary dysfunction.
Alveolar proteinosis (AP) is a rare disease characterized by alveolar accumulation of surfactant components, which impairs gas exchange. AP is classified into three groups: auto-immune AP defined by the presence of plasma autoantibodies anti-GM-CSF, the most frequent form (90% of all AP); secondary AP, mainly occurring as a consequence of haematological diseases, or following on from toxic inhalation or infections, and genetic AP, which affects almost exclusively children. AP diagnosis is suspected where chest CT-scan demonstrates interstitial lung disease with a crazy paving aspect; and confirmed by bronchoalveolar lavage, which has a milky appearance and contains periodic acid Schiff positive proteinaceous alveolar deposits. The use of surgical lung biopsy to confirm AP is less frequent nowadays. In this context, positive antibodies against GM-CSF indicates an auto-immune etiology of the AP. Concerning management, whole lung lavage is the gold standard therapy. In refractory AP, new treatments are available such as subcutaneous or inhaled GM-CSF supplementation, or rituximab infusions. The clinical course is unpredictable. Spontaneous improvement or even cure can occur, and the 5-year actuarial survival is 95%. The most frequent complications are infectious etiology.
Background
Despite few studies, a monitoring of a neuromuscular blockade with a train of four (TOF) is recommended in intensive care unit (ICU). Our objective was to compare the results of ulnar and facial TOF measurements with an overall clinical assessment for neuromuscular blockade in ICU patients treated with recommended doses of atracurium or cisatracurium, including patients with acute respiratory disease syndrome (ARDS).MethodsWe prospectively included in two ICUs 119 patients, 94 with ARDS, who required a neuromuscular blockade for more than 24 h. Three levels of neuromuscular blockade were defined: “over-paralyzed” (TOF = 0), “well-paralyzed” (TOF = 1–2), and “under-paralyzed” (TOF = 3–4). Physicians blinded for TOF counts were asked to classify patients clinically as “over-paralyzed,” “well-paralyzed,” or “under-paralyzed”. Patients were assessed two times daily.ResultsFor the whole population 996 ulnar and facial TOF measurements and clinical assessments were obtained (846 with cisatracurium and 150 with atracurium). Proportions of patients classified as over-paralyzed, well-paralyzed, and under-paralyzed based on TOF measurements and clinical assessments differed significantly (p < 0.0001). The number of observed agreements between clinical assessments and facial TOF measurements was of 19.08% (κ = 0.06) and of 17.37% with ulnar TOF measurements (κ = 0.04), while it was of 62.75% between ulnar and facial TOF measurements (κ = 0.45). Results were similar for cisatracurium and atracurium. Repeated facial TOF measurements performed on the first 4 days of mechanical ventilation in ARDS patients showed that the proportion of patients TOF = 1–2 was around 8% and did not vary significantly with time (p = 0.9), proportion of patients TOF = 3–4 increased from 24 to 40% (p = 0.01), proportion of patients TOF = 0 decreased from 71 to 53% (p = 0.005) while objectives for protective ventilation were achieved. Proportions of facial and ulnar TOF = 0 were significantly higher among patients with ICU-acquired weakness (ICU-AW) versus those who did not develop ICU-AW (51 vs. 40%, p = 0.03, and 76 vs. 62%, p = 0.006, respectively).ConclusionsThe study provides data on clinical and TOF monitoring of neuromuscular blockade, which are widely divergent in ICU patients receiving recommended doses of benzylisoquinoliniums.Electronic supplementary materialThe online version of this article (doi:10.1186/s13613-017-0234-0) contains supplementary material, which is available to authorized users.
PurposeData for ANCA-associated vasculitis (AAV) patients requiring intensive care are scarce.MethodsWe included 97 consecutive patients with acute AAV manifestations (new onset or relapsing disease), admitted to 18 intensive care units (ICUs) over a 10-year period (2002–2012). A group of 95 consecutive AAV patients with new onset or relapsing disease, admitted to two nephrology departments with acute vasculitis manifestations, constituted the control group.Results In the ICU group, patients predominantly showed granulomatosis with polyangiitis and proteinase-3 ANCAs. Compared with the non-ICU group, the ICU group showed comparable Birmingham vasculitis activity score and a higher frequency of heart, central nervous system and lungs involvements. Respiratory assistance, renal replacement therapy and vasopressors were required in 68.0, 56.7 and 26.8% of ICU patients, respectively. All but one patient (99%) received glucocorticoids, 85.6% received cyclophosphamide, and 49.5% had plasma exchanges as remission induction regimens. Fifteen (15.5%) patients died during the ICU stay. The following were significantly associated with ICU mortality in the univariate analysis: the need for respiratory assistance, the use of vasopressors, the occurrence of at least one infection event in ICU, cyclophosphamide treatment, sequential organ failure assessment at admission and simplified acute physiology score II. After adjustment on sequential organ failure assessment or infection, cyclophosphamide was no longer a risk factor for mortality. Despite a higher initial mortality rate of ICU patients within the first hospital stay (p < 0.0001), the long-term mortality of hospital survivors did not differ between ICU and non-ICU groups (18.6 and 20.4%, respectively, p = 0.36). Moreover, we observed no renal survival difference between groups after a 1-year follow-up (82.1 and 80.5%, p = 0.94).ConclusionThis study supports the idea that experiencing an ICU challenge does not impact the long-term prognosis of AAV patients.Electronic supplementary materialThe online version of this article (doi:10.1186/s13613-017-0262-9) contains supplementary material, which is available to authorized users.
In this population of critically ill nontrauma patients, at-risk drinking was independently associated with death in the ICU and within the year following ICU discharge.
The spectrum of community-acquired pneumonia (CAP) due to Chlamydophila psittaci ranges from mild, self-limited CAP, to acute respiratory failure. We performed a retrospective study of 13 consecutive patients with CAP due to C. psittaci and 51 patients with legionellosis admitted in one intensive care unit (ICU) (1993-2011). As compared to patients with legionellosis, patients with psittacosis were younger (median age 48 [38-59] vs. 60 [50-71] years, p = 0.007), less frequently smokers (38 vs. 79 %, p < 0.001), with less chronic disease (15 vs. 57 %, p = 0.02), and longer duration of symptoms before admission (median 6 [5-13] vs. 5 [3-7] days, p = 0.038). They presented with lower Simplified Acute Physiology Score II (median 28 [19-38] vs. 39 [28-46], p = 0.04) and less extensive infiltrates on chest X-rays (median 2 [1-3] vs. 3 [3-4] lobes, p = 0.007). Bird exposure was mentioned in 100 % of psittacosis cases, as compared to 5.9 % of legionellosis cases (p < 0.0001). Extrapulmonary manifestations, biological features, and mortality (15.4 vs. 21.6 %, p = 0.62) were similar in both groups. In conclusion, severe psittacosis shares many features with severe legionellosis, including extrapulmonary manifestations, biological features, and outcome. Psittacosis is an important differential diagnosis for legionellosis, especially in cases of bird exposure, younger age, and more limited disease progression over the initial few days.
International audienceDelirium is a central nervous system (CNS) dysfunction reported in up to 80 % of intensive care unit (ICU) patients associated with negative short- and long-term outcomes [1, 2]. Gastrointestinal motility disorders are frequent in ICU patients leading to frequent delayed passage of stools [3]. Because there is a bi-directional communication between the CNS and the digestive tract [4], we believed it relevant to test the hypothesis that constipation and delirium are related in ICU patients
