Outcomes of patients with coronavirus disease versus other lung infections requiring venovenous extracorporeal membrane oxygenation.

Background: Patients with Coronavirus Disease (COVID-19) often develop severe acute respiratory distress syndrome (ARDS) requiring prolonged mechanical ventilation (MV), and venovenous extracorporeal membrane oxygenation (V-V ECMO).Mortality in COVID-19 patients on V-V ECMO was exceptionally high; therefore, whether survival can be ameliorated should be investigated. Methods: We collected data from 85 patients with severe ARDS who required ECMO support at the University Hospital Magdeburg from 2014 to 2021. The patients were divided into the COVID-19 group (52 patients) and the non-COVID-19 group (33 patients). Demographic and pre-, intra-, and post-ECMO data were retrospectively recorded. The parameters of mechanical ventilation, laboratory data before using ECMO, and during ECMO were compared. Results: There was a significant difference between the two groups regarding survival: 38.5% of COVID-19 patients and 63.6% of non-COVID-19 patients survived 60 days (p = 0.024). COVID-19 patients required V-V ECMO after 6.5 days of MV, while non-COVID-19 patients required V-V ECMO after 2.0 days of MV (p = 0.048). The COVID-19 group had a greater proportion of patients with ischemic heart disease (21.2% vs 3%, p = 0.019). The rates of most complications were comparable in both groups, whereas the COVID-19 group showed a significantly higher rate of cerebral bleeding (23.1 vs 6.1%, p = 0.039) and lung bacterial superinfection (53.8% vs 9.1%, p = <0.001). Conclusion: The higher 60-days mortality among patients with COVID-19 with severe ARDS was attributable to superinfection, a higher risk of intracerebral bleeding, and the pre-existing ischemic heart disease.

Case report: Eighteen nails gun shots in the head, thorax and abdomen but still conscious at admission: A challenging patient for the cardiac surgeon!

We report an unusual case of multiple penetrating cerebral, cardiac and abdominal injuries following a suicidal attempt using a nail gun. Successful treatment required several emergency procedures and resulted from a wise interdisciplinary management and timing of surgery.

Stroke prevention in an octogenarian with atrial fibrillation, cerebral amyloid angiopathy and intracerebral hemorrhage.

Left-atrial-appendage-closure (LAAC) is suggested as alternative to antiplatelet/anticoagulant therapy (AP/AC) for stroke-prevention in patients with cerebral-amyloid-angiopathy (CAA), intracerebral hemorrhage (ICH) and atrial fibrillation (AF). Disadvantages of LAAC are the need for postinterventional AP and impairment of left atrial function, thus promoting heart-failure. Therefore, in an 83-year-old edoxaban-treated AF-patient with ICH and CAA, only antihypertensive therapy with neither AP/AC nor LAAC was recommended. Twenty-seven months without stroke/ICH support this strategy, which needs confirmation by a randomized-trial.

Total Cerebral Small Vessel Disease Score and Cerebral Bleeding Risk in Patients With Acute Stroke Treated With Intravenous Thrombolysis.

Objective: The aim of this study was to investigate the association of total cerebral small vessel disease (cSVD) score with the risk of intracerebral hemorrhage (ICH) in patients with acute ischemic stroke who received intravenous thrombolysis (IVT) using recombinant tissue-plasminogen activator (rt-PA). Methods: We retrospectively reviewed clinical data from two stroke registries of patients with acute ischemic stroke treated with IVT. We assessed the baseline magnetic resonance (MR) visible cSVD markers and total cSVD score (ranging from 0 to 4) between patients with and without ICH after IVT. Logistic regression analysis was used to determine the association of total cSVD score with the risk of ICH after IVT, adjusted for cofounders selected by least absolute shrinkage and selection operator (LASSO). We additionally performed an E-value analysis to fully explain away a specific exposure-outcome association. Receiver operating characteristic (ROC) curve analysis was used to quantify the predictive potential of the total cSVD score for any ICH after IVT. Results: Among 271 eligible patients, 55 (20.3%) patients experienced any ICH, 16 (5.9%) patients experienced a symptomatic ICH (sICH), and 5 (1.85%) patients had remote intracranial parenchymal hemorrhage (rPH). Logistic regression analysis showed that the risk of any ICH increased with increasing cSVD score [per unit increase, adjusted odds ratio (OR) 2.03, 95% CI 1.22-3.41, P = 0.007]. Sensitivity analyses using E-value revealed that it would need moderately robust unobserved confounding to render the exposure-outcome (cSVD-any ICH) association null. ROC analysis showed that compared with the National Institutes of Health Stroke Scale (NIHSS) score alone, a combination of cSVD and NIHSS score had a larger area under the curve for any ICH (0.811, 95% CI 0.756-0.866 vs. 0.784, 95% CI 0.723-0.846, P = 0.0004). Conclusion: The total cSVD score is associated with an increased risk of any ICH after IVT and improves prediction for any ICH compared with NIHSS alone.

Intracerebral bleeding after Janus-kinase inhibitor baricitinib for COVID-19.

OBJECTIVES: Intracerebral hemorrhage/bleeding (ICH) after an infection with SARS-CoV-2 (COVID-19) treated with the Janus-kinase inhibitor baricitinib has not been reported. CASE PRESENTATION: A 86yo Caucasian female suddenly developed aphasia with a systolic blood pressure of 220 mmHg. Cerebral imaging revealed an ICH in the left temporal lobe without mass effect and no need for neurosurgical intervention. Her previous history was positive for arterial hypertension, hyperlipidemia, heart failure, renal insufficiency, hyperuricemia, macula degeneration, lumbalgia, and glaucoma bilaterally. Additionally, she had experienced an infection with SARS-CoV-2 with onset 44 days earlier having been treated with ceftriaxone (2 g/d for 7 d), dexamethasone (6 mg for 6 d), and bariticinib (2 mg for 6 d). CONCLUSIONS: Though ICH was time-linked to COVID-19, a causal relation could not be unequivocally established. Whether baricitinib increased the bleeding risk remains speculative. As long as causalities between ICH and baricitinib remain unproven, it should be given with caution and only under close blood pressure monitoring.

Challenging anticoagulation cases: A case of pulmonary embolism shortly after spontaneous brain bleeding.

Venous thromboembolism (VTE) is a common complication after intracranial hemorrhage (ICH); the incidence has been reported to vary between 18% to 50% for deep vein thrombosis and between 0.5% to 5% for pulmonary embolism (PE). According to current clinical practice guidelines, patients with acute VTE should receive anticoagulant treatment for at least 3 months in the absence of contraindications. Anticoagulant treatment reduces mortality, prevents early recurrences and improves long-term outcome in patients with acute VTE. However, recent ICH is an absolute contraindication for anticoagulant treatment due to the potential increased risk of hematoma expansion or recurrent ICH. Hematoma expansion occurs in approximately a third of patients within 24 h following the diagnosis of a spontaneous ICH. The risk for recurrent ICH depends on patients' features as well as on the feature of index ICH. Limited evidence is available on the risks of therapeutic anticoagulation started shortly after ICH. Expert consensus around the introduction of therapeutic anticoagulation suggests delaying therapeutic anticoagulation for at least 2 weeks after spontaneous ICH, until the risk re-bleeding becomes acceptable. Vena cava filters should be inserted to reduce the risk for (non) fatal PE until therapeutic anticoagulation can be started; antithrombotic prophylaxis should be started as soon as possible to avoid recurrent VTE after vena cava filter insertion. For patients presenting PE with hemodynamic compromise, percutaneous embolectomy should be considered. Most patients will be able to receive anticoagulant treatment within 4 weeks following spontaneous ICH; direct oral anticoagulants are probably the treatment of choice for those ICH patients tolerating anticoagulant treatment.

Age threshold for anticoagulation in patients with atrial fibrillation: A Swedish nationwide observational study.

BACKGROUND: There is controversy as to whether patients with atrial fibrillation (AF) and perceived low risk of cerebral infarction should be treated with anticoagulants, especially at what age a cut-off treatment might be indicated. METHOD: We performed a retrospective, nationwide cohort study based on the Swedish National Patient Register and the Prescribed Drugs Register. Patients with a diagnosis of AF between July 1, 2005, and December 31, 2014, were included and divided into age categories (<55, 55-59, 60-64 and 65-74 years) and CHA2DS2-VA score of 0 and 1. Incidence rates (IR) of cerebral infarction and cerebral bleeding were calculated. Associations between outcomes from anticoagulant therapy and no therapy were calculated with Cox regression and given as hazard ratios (HR) with 95% confidence intervals (CI). RESULTS: The analyzed cohort consisted of 294,470 patients. All age categories older than 55 years on anticoagulants had lower IR and HR for cerebral infarction compared to patients off anticoagulants, from HR 0.72, 95% CI (0.54-0.96) for patients 55-59 years with 0 points according to the CHA2DS2-VA score, to HR 0.37, 95% CI (0.33-0.42) for patients 65-74 years with 1 point. Anticoagulant therapy was associated to an increased risk of cerebral bleeding in three of seven categories, <55 years with 0 point, 55-59 years with 1 point, and 65-74 years with 1 point. CONCLUSION: Anticoagulant therapy in patients with AF and age 55 years and older may be considered even if the patient has no other known risk factors for cerebral infarction.

Delayed Rupture of a Cortical Traumatic Intracranial Aneurysm.

Traumatic intracranial aneurysms are rare lesions that occur after blunt or primarily penetrating mechanisms. These are extremely fragile vessel injuries associated with significant morbidity and mortality, especially after rupture. Disease natural history, surveillance strategies, and management are based on small case series. Here we present a case of a 29-year-old male with a large epidural hematoma after blunt trauma, who underwent emergent surgical intervention. Three months postoperatively, he presented with unusual cerebral bleeding. Clinical suspicion prompted a conventional angiogram, which diagnosed a ruptured cortical traumatic intracranial aneurysm. The patient was urgently treated by surgical clipping with a good outcome.

Intracranial haemorrhage in infective endocarditis.

BACKGROUND: Although intracranial cerebral haemorrhage (ICH) complicating infective endocarditis (IE) is a critical clinical issue, its characteristics, impact, and prognosis remain poorly known. AIMS: To assess the incidence, mechanisms, risk factors and prognosis of ICH complicating left-sided IE. METHODS: In this single-centre study, 963 patients with possible or definite left-sided IE were included from January 2000 to December 2015. RESULTS: Sixty-eight (7%) patients had an ICH (mean age 57±13 years; 75% male). ICH was classified into three groups according to mechanism: ruptured mycotic aneurysm (n=22; 32%); haemorrhage after ischaemic stroke (n=27; 40%); and undetermined aetiology (n=19; 28%). Five variables were independently associated with ICH: platelet count<150×109/L (odds ratio [OR] 2.3, 95% confidence interval [CI] 1.01-5.4; P=0.049); severe valve regurgitation (OR 3.2, 95% CI 1.3-7.6; P=0.008); ischaemic stroke (OR 4.2, 95% CI 1.9-9.4; P<0.001); other symptomatic systemic embolism (OR 14.1, 95% CI 5.1-38.9; P<0.001); and presence of mycotic aneurysm (OR 100.2, 95% CI 29.2-343.7; P<0.001). Overall, 237 (24.6%) patients died within 2.3 (0.7-10.4) months of follow-up. ICH was not associated with increased mortality (P not significant). However, the 1-year mortality rate differed according to ICH mechanism: 14%, 15% and 45% in patients with ruptured mycotic aneurysm, haemorrhage after ischaemic stroke and undetermined aetiology, respectively (P=0.03). In patients with an ICH, mortality was higher in non-operated versus operated patients when cardiac surgery was indicated (P=0.005). No operated patient had neurological deterioration. CONCLUSIONS: ICH is a common complication of left-sided IE. The impact on prognosis is dependent on mechanism (haemorrhage of undetermined aetiology). We observed a higher mortality rate in patients who had conservative treatment when cardiac surgery was indicated compared with in those who underwent cardiac surgery.

Resuming anticoagulant therapy after intracerebral bleeding.

The clinical benefit of resuming anticoagulant treatment after an anticoagulants-associated intracranial hemorrhage (ICH) is debated. No randomized trial has been conducted on this particular clinical issue. The risk of ICH recurrence from resuming anticoagulant therapy is expected to be higher after index lobar than deep ICH and in patients with not amendable risk factors for ICH. Retrospective studies have recently shown improved survival with resumption of treatment after index anticoagulants-associated ICH. Based on these evidences and on the risk for thromboembolic events without anticoagulant treatment, resumption of anticoagulation should be considered in all patients with mechanical heart valve prosthesis and in those with amendable risk factors for anticoagulants-associated ICH. Resumption with direct oral anticoagulants appears a reasonable option for non-valvular atrial fibrillation (NVAF) patients at moderate to high thromboembolic risk after deep ICH and for selected NVAF patients at high thromboembolic risk after lobar ICH. For VTE patients at high risk for recurrence, resumption of anticoagulation or insertion of vena cava filter should be tailored on the estimated risk for ICH recurrence.

Fatal intracerebral bleeding under rivaroxaban.

Rivaroxaban is a factor-Xa-inhibitor which has been shown to be non-inferior to the vitamin-K-antagonist (VKA) warfarin in atrial fibrillation patients. In the manufacturer-sponsored trial, the rate of intracranial hemorrhage in rivaroxaban-treated patients was lower than in VKA-treated. It is unknown if this advantage of rivaroxaban is also present outside clinical trials. We report a patient with fatal cerebral bleeding 4months after initiation of rivaroxaban. Bleeding might be favored by hypertension, hypoalbuminemia, renal impairment, hepatopathy and drug-drug interactions of rivaroxaban with amiodarone and bisoprolol. Patients have to be monitored closely after initiation of rivaroxaban, especially if they are treated with possibly interacting drugs. Additionally, hepatic function, albumin level, and renal function have to be closely monitored. Therapy with VKA seems more convenient, safer and more favorable for the patient than rivaroxaban with its associated uncertainties concerning metabolization and drug-drug interactions and no possibility to reverse its activity in emergency situations.

An unusual prostate-specific antigen decrease in an advanced castration-resistant prostate cancer patient with intracerebral hemorrhage subsequently treated with luteinizing hormone-releasing hormone antagonist.

An unusual prostate-specific antigen (PSA) decrease in a Japanese patient with advanced castration-resistant prostate cancer (CRPC) treated with luteinizing hormone-releasing hormone (LH-RH) antagonist after cerebral bleeding was presented. There have been no previous reports that cerebral bleeding or trepanation/drainage of hematoma decreased PSA level, which would make this the first. The LH-RH antagonist may be only one reason for the PSA decrease. More cases need to be accumulated and and further investigation is needed to clarify if intracerebral bleeding or an LH-RH antagonist can decrease PSA in such advanced CRPC cases.
