Clinical features and outcomes of patients with pancreatic cancer requiring unplanned medical ICU admission: A retrospective multicenter study

BACKGROUND

We sought to describe the reasons for intensive care unit (ICU) admission and outcomes of patients with pancreatic cancer requiring unplanned medical ICU admission.

PATIENTS AND METHODS

Retrospective cohort study in five ICUs from 2009 to 2020. All patients with pancreatic cancer admitted to the ICU were included. Patients having undergone recent surgery were excluded (< 4 weeks).

RESULTS

269 patients were included. Tumors were mainly adenocarcinoma (90%). Main reason for admission was sepsis/septic shock (32%) with a biliary tract infection in 44 (51%) patients. Second reason for admission was gastrointestinal bleeding (28%). ICU and 3-month mortality rates were 26% and 59% respectively. Performance status 3-4 (odds ratio OR 3.58), disease status (responsive/stable -ref-, newly diagnosed OR 3.25, progressive OR 5.99), mechanical ventilation (OR 8.03), vasopressors (OR 4.19), SAPS 2 (OR 1.69) and pH (OR 0.02) were independently associated with ICU mortality. Performance status 3-4 (Hazard ratio HR 1.96) and disease status (responsive/stable -ref-, newly diagnosed HR 2.67, progressive HR 4.14) were associated with 3-month mortality.

CONCLUSION

Reasons for ICU admissions of pancreatic cancer patients differ from those observed in other solid cancer. Short- and medium-term mortality are strongly influenced by performance status and disease status at ICU admission.

[Metabolic encephalopathies]

Metabolic encephalopathies (ME) are a common cause of admission to emergency rooms, to hospitalization wards or to intensive care units. They could account for 10 to 20% of causes of comatose states in ICU and could be associated to a poor outcome especially in older patients. Nevertheless, they are often reversible and are associated with a favorable outcome when diagnosed and rapidly treated. They correspond to an altered brain functioning secondary to the deficiency of a substance that is mandatory for the normal brain functioning or to the accumulation of a substance that can be either endogenous or exogenous. It preferably occurs in co-morbid patients, complicating its diagnosis and its management. Altered brain functioning, going from mild neuropsychological impairment to coma, movement disorders especially myoclonus and the absence of any obvious differential diagnosis are highly suggestive of the diagnosis. Whereas some biological samplings and brain MRI are essential to rule out differential diagnosis, some others, such as electroencephalogram, may be able to propose important clues in favor of the diagnosis. Once simple symptomatic measures are introduced, the treatment consists mainly in the correction of the cause. Specific treatment options are only seldom available for ME; this is the case for hepatic encephalopathy and some drug-induced encephalopathies. We will successively describe in this review the main pathophysiological mechanisms, the main causes, favoring circumstances of ME, the differential diagnosis to rule out and the etiological work-up for the diagnosis. Finally, a diagnostic and therapeutic strategy for the care of patients with ME will be proposed.

Early-TIPSS placement prevents rebleeding in high-risk patients with variceal bleeding, without improving survival

BACKGROUND

Early-TIPSS (transjugular intrahepatic portosystemic shunt) placement may improve rebleeding and reduce 1-year mortality, compared to standard management in high-risk patients with cirrhosis and variceal bleeding.

AIM

To obtain external validation of this therapeutic approach.

METHODS

We performed a prospective study including all consecutive patients with Child-Pugh C 10-13 cirrhosis or Child-Pugh B with active bleeding at endoscopy admitted to our ICU between March 2011 and February 2013 for variceal bleeding. TIPSS were placed within 72 h after stabilisation. Patients were matched for gender, age, Child-Pugh score, MELD score and to patients from a historical cohort hospitalised before March 2011.

RESULTS

31/128 patients with cirrhosis (77.4% men, mean age 53.2 ± 9.0 years old, MELD score 20.9 ± 6.9, Child-Pugh C: 77.4%) admitted for acute variceal bleeding between March 2011 and February 2013 (TIPSS+ group) were matched to 31 historical patients (TIPSS- group). Uncontrolled bleeding occurred in 1/31 patients in the TIPSS+ group vs. 2/31 patients in TIPSS- group (P = 0.55). The 1-year probability of being free of rebleeding was higher in the TIPSS+ group (97% vs. 51%, P < 0.001). Actuarial 1-year survival was not different between the two groups (66.8 ± 9.4% vs. 74.2 ± 7.8%, P = 0.78). Acute cardiac failure occurred more frequently in the TIPSS+ group (25.8% vs. 6.4%, P = 0.03).

CONCLUSIONS

Early-TIPSS placement effectively prevents rebleeding in high-risk patients with variceal bleeding but does not significantly improve survival. This might be due to the high proportion of patients with Child-Pugh C cirrhosis in our series. Cardiac failure may play a role and must be investigated before the procedure, when possible.

Peptic ulcer bleeding in patients with or without cirrhosis: different diseases but the same prognosis?

BACKGROUND

Physiopathology and prognosis of peptic ulcer bleeding (PUB) have never been described in cirrhotic patients.

AIM

To assess risk factors and outcome of PUB in two groups of patients with PUB with or without cirrhosis.

METHODS

We included prospectively all patients with PUB referred to our ICU of Hepatology and Gastroenterology between January 2008 and March 2011. All patients were treated according to international recommendations. Diagnosis of cirrhosis was based on clinical, biological and morphological exams. Aetiologies, characteristics and outcomes of PUB were compared in cirrhotic vs. noncirrhotic patients.

RESULTS

A total of 203 patients with PUB were included prospectively. Twenty-nine patients had cirrhosis (group Cirr+), and 174 patients had no cirrhosis (group Cirr-). Demographic data were similar between the two groups except for age and alcohol consumption. Aetiology of cirrhosis was alcohol in 97% of cirrhotic patients. Characteristics of PUB were not different between the two groups. Ninety-three per cent of patients with cirrhosis had endoscopic portal hypertension. Aetiology of PUB was different between the group Cirr+ and Cirr- (Helicobacter pylori = 10.3% vs. 48.8%, P < 0.0001; NSAID's = 17.2% vs. 54.0%, P < 0.0001; idiopathic PUB = 79.3% vs. 23.8%, P < 0.0001). Outcome was comparable concerning re-bleeding (7.0% vs. 6.9%, P = 0.31), need for arterial embolisation (10.3 vs. 8.6%, P = 0.76), need for salvage surgery (0 vs. 1.7%, P = 0.31) and mortality (3.0% vs. 1.1%, P = 0.87).

CONCLUSIONS

Physiopathology of PUB seems to be different in patients with cirrhosis. In cirrhotic patients, PUB occurs almost only in alcoholics. In our series, prognosis was similar to general population. PUB in cirrhosis might be related to portal hypertension and/or alcohol.

[Medicolegal aspects of acute alcoholic intoxication]

The médico-legal aspects of acute alcohol intoxication mainly concern driving while under the effect of alcohol and the regulation thereof. In France, the legal limit is 0.8 mg of alcohol per litre of blood and 0.4 mg per litre of expired air. Examination is made by breathalyser on expired air. In the blood, measurement is performed by oxidation-reduction or gas chromatography, and in the expired air, by alcoholometry. Determination of the level of blood alcohol remains only approximate and a minimal indicator, given the variable number of factors that may intervene.

[Sudden crib death. Experience in a referral center 1986-1991]

BACKGROUND

Sudden infant death syndrome (SIDS) may have several etiologies, all of which must be identified in order to recognize those infants believed to be at risk. One of the best ways to do this is by prospective studies on a large population of infants who died of SIDS.

METHODS

A total of 171 infants who died from SIDS between January 1, 1986 and June 30, 1991, were studied. 154 infants were completely investigated, including a post mortem examination. They were assigned to one of 4 groups, according to whether death was due to diseases of poor prognosis (group A), diseases that are occasionally fatal but potentially treatable (group B), minor diseases not normally fatal (group C), or was essentially unexplained (group D).

RESULTS

The classical risk factors for SIDS were found in this population: incidence peaked in males (sex-ratio 1.5), during the cold seasons (62%), between 1 and 6 months of age (94%), mainly between 1 and 4 months of age (84%). Symptoms were definitely present during the 2 days before death in 50%. 20% of cases had clinical histories of congenital disease, complicated or recurrent postnatal disease, or fulminant recent disease. Group A included 107 infants (69% of the 154 completely investigated patients). Premature birth (17.5%) and low birth weight for gestational age (10.5%) were more frequent in our series than in the normal population.

CONCLUSION

The cause of death was identified in about 75% of cases. This possibility improves management of further siblings of SIDS victims even though the variety of risk factors makes prevention of SIDS difficult.

[Pulmonary complications in "sniffers"]

When a sudden death occurs, a necropsy is of the upmost value, but sometimes it does not yield the anticipated benefit; in this situation histological study of the specimens may help the diagnosis. We describe two decreased "sniffers" with pulmonary lesions that could have explained their sudden deaths. The histological appearance is often not recognised and considerably worsens the prognosis in subjects inhaling certain drugs.

[Acute ethylene glycol poisoning]

During last 7 years, 13 cases of acute ethylene glycol poisoning have been observed with 4 fatal outbreaks. All cases--except one--were accidental. Six patients had drunk a mixture of antifreeze in water as they were lost in a desert. A patient who had taken 970 ml of ethylene glycol survived. In one case, death was due to irreversible brain damage; two other fatalities occurred from cardiorespiratory distress. CNS involvement was noticed in 8 cases and acute renal failure-constantly controlled-occurred in 9 patients. Post mortem examination has shown bi-refringent calcium oxalate crystals in both kidney and brain. Specific treatment with ethanol has been performed in 3 cases with ingestion of large amounts of toxic who were seen before definitive renal lesions have occurred. Emphasis is placed in symptomatic treatment including gastric lavage, extrarenal epuration and conservative management.
