RESUMEN

BACKGROUND & AIMS: There are uncertainties regarding the burden of liver disease in patients with type 2 diabetes (T2D). Thus, we aimed to quantify the burden of liver disease, identify risk factors, and estimate attributable risks in patients with T2D. METHODS: We measured adjusted hazard ratios of liver disease progression to hepatocellular carcinoma and/or decompensated cirrhosis in a 2010-2020 retrospective, bicentric, longitudinal, cohort of 52,066 hospitalized patients with T2D. RESULTS: Mean age was 64±14 years and 58% were men. Alcohol use disorders accounted for 57% of liver-related complications and were associated with all liver-related risk factors. Non-metabolic liver-related risk factors accounted for 37% of the liver burden. T2D control was not associated with liver disease progression. The incidence (95% CI) of liver-related complications and of competing mortality were 3.9 (3.5-4.3) and 27.8 (26.7-28.9) per 1,000 person-years at risk, respectively. The cumulative incidence of liver disease progression exceeded the cumulative incidence of competing mortality only in the presence of well-identified risk factors of liver disease progression, including alcohol use. The incidence of hepatocellular carcinoma was 0.3 (95% CI 0.1-0.5) per 1,000 person-years in patients with obesity and it increased with age. The adjusted hazard ratios of liver disease progression were 55.7 (40.5-76.6), 3.5 (2.3-5.2), 8.9 (6.9-11.5), and 1.5 (1.1-2.1), for alcohol-related liver disease, alcohol use disorders without alcohol-related liver disease, non-metabolic liver-related risk factors, and obesity, respectively. The attributable fractions of alcohol use disorders, non-metabolic liver-related risk factors, and obesity to the liver burden were 55%, 14%, and 7%, respectively. CONCLUSIONS: In this analysis of data from 2 hospital-based cohorts of patients with T2D, alcohol use disorders, rather than obesity, contributed to most of the liver burden. These results suggest that patients with T2D should be advised to drink minimal amounts of alcohol. LAY SUMMARY: There is uncertainty on the burden of liver-related complications in patients with type 2 diabetes. We studied the risks of liver cancer and complications of liver disease in over 50,000 patients with type 2 diabetes. We found that alcohol was the main factor associated with complications of liver disease. This finding has major implications on the alcohol advice given to patients with type 2 diabetes.

RESUMEN

Transplant and patient survival are the validated endpoints to assess the success of liver transplantation (LT). This study evaluates arterial and biliary complication-free survival (ABCFS) as a new metric. ABC, considered as an event, was an arterial or biliary complication of Dindo-Clavien grade ≥III complication dated at the interventional, endoscopic, or surgical treatment required to correct it. ABCFS was defined as the time from the date of LT to the dates of first ABC, death, relisting, or last follow-up (transplant survival is time from LT to repeat LT or death). Following primary whole LT (n = 532), 106 ABCs occurred and 99 (93%) occurred during the first year after LT. An ABC occurring during the first year after LT (overall rate 19%) was an independent factor associated with transplant survival (hazard ratio [HR], 3.17; P < 0.001) and patient survival (HR, 2.7; P = 0.002) in univariate and multivariate analyses. This result was confirmed after extension of the cohort to split-liver graft, donation after circulatory death, or re-LT (n = 658). Data from 2 external cohorts of primary whole LTs (n = 249 and 229, respectively) confirmed that the first-year ABC was an independent prognostic factor for transplant survival but not for patient survival. ABCFS was correlated with transplant and patient survival (ρ = 0.85 [95% CI, 0.78-0.90] and 0.81 [95% CI, 0.71-0.88], respectively). Preoperative factors known to influence 5-year transplant survival influenced ABCFS after 1 year of follow-up. The 1-year ABCFS was indicative of 5-year transplant survival. ABCFS is a reproducible metric to evaluate the results of LT after 1 year of follow-up and could serve as a new endpoint in clinical trials.

RESUMEN

Sarcoidosis is a rare disease of unknown cause with wide heterogeneity in clinical features and outcomes. We aimed to explore sarcoidosis phenotypes and their clinical relevance with particular attention to extrapulmonary subgroups.The Epidemiology of Sarcoidosis (EpiSarc) study is a French retrospective multicentre study. Sarcoidosis patients were identified through national hospitalisation records using appropriate codes from 11 hospital centres between 2013 and 2016 according to a standardised protocol. Medical charts were reviewed. The phenotypes of sarcoidosis were defined using a hierarchical cluster analysis.A total of 1237 patients were included (562 men and 675 women). The mean age at sarcoidosis diagnosis was 43.5±13 years. Hierarchical cluster analysis identified five distinct phenotypes according to organ involvement and disease type and symptoms: 1) erythema nodosum, joint involvement and hilar lymph nodes (n=180); 2) eye, neurological, digestive and kidney involvement (n=137); 3) pulmonary involvement with fibrosis and heart involvement (n=630); 4) lupus pernio and a high percentage of severe involvement (n=41); and 5) hepatosplenic, peripheral lymph node and bone involvement (n=249). Phenotype 1 was associated with being European/Caucasian and female and with non-manual work, phenotype 2 with being European/Caucasian, and phenotypes 3 and 5 with being non-European/Caucasian. The labour worker proportion was significantly lower in phenotype 5 than in the other phenotypes.This multicentre study confirms the existence of distinct phenotypes of sarcoidosis, with a non-random distribution of organ involvement. These phenotypes differ according to sex, geographical origin and socioprofessional category.

RESUMEN

Background This study provides a detailed imaging assessment in a large series of patients infected with coronavirus disease 2019 (COVID-19) and presenting with neurologic manifestations. Purpose To review the MRI findings associated with acute neurologic manifestations in patients with COVID-19. Materials and Methods This was a cross-sectional study conducted between March 23 and May 7, 2020, at the Pitié-Salpêtrière Hospital, a reference center for COVID-19 in the Paris area. Adult patients were included if they had a diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection with acute neurologic manifestations and referral for brain MRI. Patients with a prior history of neurologic disease were excluded. The characteristics and frequency of different MRI features were investigated. The findings were analyzed separately in patients in intensive care units (ICUs) and other departments (non-ICU). Results During the inclusion period, 1176 patients suspected of having COVID-19 were hospitalized. Of 308 patients with acute neurologic symptoms, 73 met the inclusion criteria and were included (23.7%): thirty-five patients were in the ICU (47.9%) and 38 were not (52.1%). The mean age was 58.5 years ± 15.6 [standard deviation], with a male predominance (65.8% vs 34.2%). Forty-three patients had abnormal MRI findings 2-4 weeks after symptom onset (58.9%), including 17 with acute ischemic infarct (23.3%), one with a deep venous thrombosis (1.4%), eight with multiple microhemorrhages (11.3%), 22 with perfusion abnormalities (47.7%), and three with restricted diffusion foci within the corpus callosum consistent with cytotoxic lesions of the corpus callosum (4.1%). Multifocal white matter-enhancing lesions were seen in four patients in the ICU (5%). Basal ganglia abnormalities were seen in four other patients (5%). Cerebrospinal fluid analyses were negative for SARS-CoV-2 in all patients tested (n = 39). Conclusion In addition to cerebrovascular lesions, perfusion abnormalities, cytotoxic lesions of the corpus callosum, and intensive care unit-related complications, we identified two patterns including white matter-enhancing lesions and basal ganglia abnormalities that could be related to severe acute respiratory syndrome coronavirus 2 infection. © RSNA, 2020 Online supplemental material is available for this article.

RESUMEN

BACKGROUND: Keratins (Ks) represent tissue-specific proteins. K18 is produced in hepatocytes while K19, the most widely used ductular reaction (DR) marker, is found in cholangiocytes and hepatic progenitor cells. K18-based serum fragments are commonly used liver disease predictors, while K19-based serum fragments detected through CYFRA21-1 are established tumor but not liver disease markers yet. Since DR reflects the severity of the underlying liver disease, we systematically evaluated the usefulness of CYFRA21-1 in different liver disease severities and etiologies. METHODS: Hepatic expression of ductular keratins (K7/K19/K23) was analyzed in 57 patients with chronic liver disease (cohort i). Serum CYFRA21-1 levels were measured in 333 Austrians with advanced chronic liver disease (ACLD) of various etiologies undergoing hepatic venous pressure gradient (HVPG) measurement (cohort ii), 231 French patients with alcoholic cirrhosis (cohort iii), and 280 hospitalized Germans with decompensated cirrhosis of various etiologies (cohort iv). RESULTS: (i) Hepatic K19 levels were comparable among F0-F3 fibrosis stages, but increased in cirrhosis. Hepatic K19 mRNA strongly correlated with the levels of other DR-specific keratins. (ii) In ACLD, increased serum CYFRA21-1 associated with the presence of clinically significant portal hypertension (CSPH; HVPG ≥ 10 mmHg) (OR = 5.87 [2.95-11.68]) and mortality (HR = 3.02 [1.78-5.13]; median follow-up 22 months). (iii) In alcoholic cirrhosis, elevated serum CYFRA21-1 indicated increased risk of death/liver transplantation (HR = 2.59 [1.64-4.09]) and of HCC (HR = 1.74 [1.02-2.96]) over the long term (median follow-up 73 months). (iv) In decompensated cirrhosis, higher serum CYFRA21-1 predicted 90-day mortality (HR = 2.97 [1.92-4.60]) with a moderate accuracy (AUROC 0.64), independently from established prognostic scores. CONCLUSIONS: Hepatic K19 mRNA and serum CYFRA21-1 levels rise in cirrhosis. Increased CYFRA21-1 levels associate with the presence of CSPH and reliably indicate mortality in the short and long term independently of conventional liver biochemistry markers or scoring systems. Hence, the widely available serum CYFRA21-1 constitutes a novel, DR-related marker with prognostic implications in patients with different settings of advanced liver disease.

RESUMEN

Noninvasive assessment of disease activity in patients with nonalcoholic fatty liver disease (NAFLD) and alcoholic liver disease (ALD) is still unsettled, but essential for the evaluation of disease progression. We here studied the association of total (M65) and caspase-cleaved (M30) serum keratin-18 fragments (n = 204) with histological parameters (n = 106) in heavy drinkers primarily admitted for alcohol withdrawal before and after alcohol detoxification. An age-, sex-, and fibrosis-stage matched NAFLD cohort (n = 30) was used for comparison. The prognostic value of M30 and M65 levels were assessed in an additional prospectively followed-up cohort of 230 patients with alcoholic cirrhosis (AC) using competing risk analyses. Among the histological parameters, both M30/65 correlated significantly and better than any other serum marker with apoptosis and liver damage, such as ballooning (r = 0.65; P < 0.001), followed by lobular inflammation (0.48; P < 0.001), steatosis (0.46; P < 0.001), but less with fibrosis (0.24; P < 0.001). Area under the receiver operating characteristics curves to detect ballooning, steatosis, or steatohepatitis (SH) were slightly better for M30 (P < 0.005). Optimal M30 cut-off values for mild and severe ballooning were 330 and 420 U/L, and 290 and 330 U/L for SH grades 1 and 2. No significant differences of M30/65 were found between the matched NAFLD and ALD cohort. In contrast to aspartate-amino-transferase and M65, M30 levels increased significantly from 391 to 518 U/L during alcohol detoxification. Moreover, levels of M30 and M65 predicted non-hepatocellular carcinoma liver-related mortality in patients with AC during a mean observation interval of 67.2 months. CONCLUSION: Our data suggest M30 as highly specific marker of liver apoptosis both in ALD and NAFLD. In addition, hepatocellular apoptosis, as determined by M30 levels, occurs during alcohol withdrawal, and survival data point toward a novel underestimated role of apoptosis in patients with ALD.

RESUMEN

BACKGROUND & AIMS: Iron constitutes a potentially toxic element and consequently, hepatic iron overload may accelerate liver disease progression and development of hepatocellular carcinoma (HCC). Hepcidin is the central negative regulator of iron metabolism that is produced primarily by the liver. METHODS: To study the prognostic significance of serum hepcidin, we assessed the influence of baseline serum hepcidin levels on the outcome of a French cohort encompassing 237 patients with alcoholic cirrhosis prospectively followed up in the setting of HCC screening. RESULTS: Hepcidin values correlated weakly with serum ferritin levels (r = 0.33) and hepatic iron scores (r = 0.3). After a median follow-up of 68 months, patients with baseline lower hepcidin level had a higher risk of HCC occurrence [hazard ratio, HR = 1.76 (1.01-3.06), P = 0.031] and overall death [HR = 1.63 (1.07-2.44), P = 0.019]. According to Cox multivariate analyses, lower hepcidin levels were independently associated with death [HR = 2.84 (1.29-6.25), P = 0.009] along with higher Child-Pugh score while HCC occurrence was mainly associated with clinical confounders interfering with iron metabolism (older age and higher BMI, adjusted P-value for hepcidin = 0.119). CONCLUSIONS: In conclusion, low-serum hepcidin levels in patients with alcoholic cirrhosis bear a long-term prognostic significance warranting further explorations.

RESUMEN

BACKGROUND & AIMS: Genetic polymorphisms modulate the expression of proinflammatory cytokines. We prospectively assessed the influence of 6 single nucleotide polymorphisms (SNPs) in TNFα, IL6, and IL1ß genes on the risk of hepatocellular carcinoma (HCC) in patients with cirrhosis. METHODS: TNFα (G-238A, C-863A, G-308A), IL6 (C-174G), and IL1ß (C-31T, C-511T) SNPs were assessed in 232 alcoholics and 253 HCV-infected patients with biopsy-proven cirrhosis, prospectively followed-up and screened for HCC. Their influence on HCC development was assessed using the Kaplan-Meier method. RESULTS: These variants did not influence the risk of HCC in alcoholic patients. Conversely, two variants influenced the risk of HCC occurrence in patients with HCV-related cirrhosis, namely the TNFα-308 (A) allele (HR = 2.4 [1.6-3.7], Log-rank <0.0001) and the IL1ß-31 (T) allele (HR = 1.5 [1.1-2.1], Log-rank = 0.004). When stratifying HCV-infected patients into four genotypic associations expected to progressively increase TNFα and IL1ß production, we observed increasing risk of HCC occurrence (Log-rank <0.0001) from group 1 to 4. The TNFα-308 (A) allele was the only genetic trait independently associated with risk of HCC in these patients, along with older age, male gender, BMI, and platelet count. These variables led to construction of a predictive score able to separate patients with HCV-related cirrhosis into three subgroups with progressively increasing 5-year cumulative incidences of 4.7%, 14.1%, and 36.3%, respectively (Log-rank <0.0001). CONCLUSIONS: Genetic heterogeneity in the TNFα and IL1ß gene promoters influences the risk of HCC in patients with HCV-induced cirrhosis. These genetic data, when incorporated into clinical scores, are able to refine selection of risk classes of HCC.

RESUMEN

BACKGROUND & AIMS: Several studies have reported an association between the genetic variant rs738409 (G) in the PNPLA3 gene and the risk of cirrhosis in various liver diseases. Our purpose was to assess the influence of this polymorphism on the risk of hepatocellular carcinoma (HCC) occurrence in two distinct longitudinal cohorts of patients with cirrhosis as well as its possible usefulness in HCC-risk model prediction. METHODS: PNPLA3 rs738409 genotypes were assessed in 279 patients with alcoholic- and 253 patients with HCV-related cirrhosis. These patients were followed-up and screened for the risk of HCC, and the influence of rs738409 on the occurrence of liver cancer was assessed using the Kaplan-Meier method, then according to the multivariate Cox model. RESULTS: In patients with HCV-related cirrhosis, rs738409 genotypes did not influence the risk of HCC development (log-rank = 0.7) or death (log-rank = 0.2). Conversely, in patients with alcoholic cirrhosis, the rs738409 (GG) genotype was an independent risk factor for HCC occurrence (HR = 1.72 [1.21-2.45], log-rank = 0.002) as well as older age, male gender, and higher BMI. Combining these features enabled HCC-risk stratification of this population into three groups with the 6-year cumulative incidence ranging from 3.4% (low risk, n = 58), 12.2% (intermediate risk, n = 163), and 51.7% (high risk, n = 58), respectively (HR = 4.3 [2.7-6.4]; log-rank <0.0001). CONCLUSIONS: This study provides key data that affirm the influence of the rs738409 (GG) genotype on the occurrence of HCC in patients with alcoholic cirrhosis. Its combination with clinical features refines the selection of patients at higher risk of liver cancer development.

RESUMEN

Background & Aims: There is concern about the burden of liver injury in patients with cancer exposed to immune checkpoints inhibitors (ICIs). Methods: In a retrospective cohort study, we evaluated the likelihood of grade 3/4 liver injury, of grade 3/4 cholestatic liver injury, and of liver failure, as per the Common Terminology Criteria for Adverse Events (CTCAE) version 5, following treatment with ICIs. We compared these occurrences with a group of cancer patients who were propensity-matched and treated with conventional chemotherapy. For all ICI patients experiencing grade 3/4 liver injury, we conducted a causality assessment using the RUCAM method and examined patient outcomes. Results: Among 952 patients (median [IQR] age 66 [57-73] years, 64% males) who were treated with ICI between January 1, 2015, and December 31, 2019, a total of 86 (9%) progressed to grade 3/4 liver injury, and liver failure was not observed. Anti-PD-(L)1/anti-CTLA-4 antibodies combinations (adjusted hazard ratio 3.36 [95% CI: 1.67-6.79]; p <0.001), and chronic hepatitis B (adjusted hazard ratio 5.48 [95% CI: 1.62-18.5]; p = 0.006], were independent risk factors. Liver injury was attributed to ICI treatment in 19 (2.0%) patients. Patients with ICI toxicity typically presented with granulomatous hepatitis or cholangiocyte inflammation. ICI withdrawal was associated with cancer progression and mortality. Re-introduction of ICI was not associated with recurrent grade 3/4 liver injury. Compared with matched patients treated with conventional, non-ICI-based chemotherapy, anti-PD-(L)1/anti-CTLA-4 combinations (p <0.001) and anti-PD-(L)1 monotherapies (p = 0.053) increased the risk of grade 3/4 liver injury and of grade 3/4 cholestatic liver injury, respectively. Conclusions: An increased risk of grade 3/4 liver injury under anti-PD-(L)1/anti-CTLA-4 antibodies was observed, whereas no substantial increase in the likelihood of liver failure occurred even after treatment reintroduction. Impact and implications: There is concern about liver injury in patients with cancer exposed to immune checkpoints inhibitors (ICIs). We investigated the burden of grade 3/4 liver injury after treatment with ICIs in a multicentric cohort of patients with cancer. Overall, a 9% incidence of grade 3/4 liver injury was detected after ICIs, and direct ICI hepatotoxicity was demonstrated in 2% of patients. Anti-PD-(L)1/Anti-CTLA-4 antibody combinations, and chronic HBV infection were independent risk factors. ICI withdrawal for grade 3/4 liver injury was associated with cancer progression. Re-introduction of ICI treatment was not associated with recurrent grade 3/4 liver injury.

RESUMEN

BACKGROUND & AIMS: Genetic dimorphisms modulate the activities of several pro- or antioxidant enzymes, including myeloperoxidase (MPO), catalase (CAT), manganese superoxide dismutase (SOD2), and glutathione peroxidase 1 (GPx1). We assessed the role of the G(-463)A-MPO, T(-262)C-CAT, Ala16Val-SOD2, and Pro198Leu-GPx1 variants in modulating HCC development in patients with HCV-induced cirrhosis. METHODS: Two hundred and five patients with HCV-induced, biopsy-proven cirrhosis but without detectable HCC at inclusion were prospectively followed-up for HCC development. The influence of various genotypes on HCC occurrence was assessed with the Kaplan-Meier method. RESULTS: During follow-up (103.2±3.4 months), 84 patients (41%) developed HCC, and 66 died. Whereas the Ala16Val-SOD2 or Pro198Leu-GPx1 dimorphisms did not modulate the risk, HCC occurrence was increased in patients with either the homozygous GG-MPO genotype (HR=2.8 [1.7-4.4]; first quartile time to HCC occurrence: 45 vs. 96 months; LogRank <0.0001) or the homozygous CC-CAT genotype (HR=1.74 [1.06-2.82]; first quartile time to HCC occurrence: 55 vs. 96 months; LogRank=0.02). Compared to patients with neither of these two at risk factors, patients with only the CC-CAT genotype had a HR of 2.05 [0.9-4.6] (p=0.08) and patients with only the GG-MPO genotype had a HR of 3.8 [1.5-9.1] (p=0.002), while patients with both risk factors had an HR of 4.8 [2.2-10.4] (p<0.0001). However, only the GG-MPO genotype was independently associated with the HCC risk in multivariate Cox analysis. CONCLUSIONS: The high activity-associated GG-MPO genotype increases the rate of HCC occurrence in patients with HCV-induced cirrhosis.

RESUMEN

BACKGROUND: Keratins 8/18 (K8/K18) are established hepatoprotective proteins and K8/K18 variants predispose to development and adverse outcome of multiple liver disorders. The importance of K8/K18 in alcoholic liver disease as well as in established cirrhosis remains unknown. METHODS: We analyzed the K8 mutational hot-spots in 261 prospectively followed-up patients with alcoholic cirrhosis (mean follow-up 65 months). PCR-amplified samples were pre-screened by denaturing high-performance liquid chromatography and conspicuous samples were sequenced. RESULTS: 67 patients developed hepatocellular carcinoma (HCC) and 133 died. Fourteen patients harbored amino-acid-altering K8 variants (5xG62C, 8xR341H). The presence of K8 variants did not associate with development of HCC (log-rank=0.5) or death (log-rank=0.7) and no significant associations were obtained for the single K8 variants after a correction for multiple testing was performed. CONCLUSIONS: Keratin variants are expressed in a low percentage of patients with alcoholic cirrhosis and do not influence HCC development. Further studies conducted in larger prospective cohorts are needed to find out whether presence of K8 R341H variant predispose to non-HCC-related liver mortality.

RESUMEN

OBJECTIVES: Despite the quick implementation of infection prevention and control procedures and the use of personal protective equipment within healthcare facilities, many cases of nosocomial COVID-19 transmission have been reported. We aimed to estimate the frequency and impact of healthcare-associated COVID-19 (HA-COVID-19) and evaluate the contribution of whole-genome sequencing (WGS) in cluster investigation. METHODS: We estimated the frequency and mortality of HA-COVID-19 infections from September 1 to November 30, 2020, with a focus on the evolution of hospitalized community-associated COVID-19 (CA-COVID-19) cases and cases detected among healthcare workers (HCWs) within the Sorbonne University Hospital Group (Paris, France). We thoroughly examined 12 clusters through epidemiological investigations and WGS. RESULTS: Overall, 209 cases of HA-COVID-19 were reported. Evolution of HA-COVID-19 incidence closely correlated with the incidence of CA-COVID-19 and COVID-19 among HCWs. During the study period, 13.9 % of hospitalized patients with COVID-19 were infected in the hospital and the 30-day mortality rate of HA-COVID-19 was 31.5 %. Nosocomial transmission of SARS-CoV-2 led to clusters involving both patients and HCWs. WGS allowed the exclusion of one-third of cases initially assigned to a cluster. CONCLUSIONS: WGS analysis combined with comprehensive epidemiological investigations is essential to understand transmission routes and adapt the IPC response to protect both patients and HCWs.

RESUMEN

Kidney transplant recipients (KTRs) tend to develop infections with characteristic epidemiology, presentation, and outcome. While infective endocarditis (IE) is among such complications in KTRs, the literature is scarce. We describe the presentation, epidemiology, and factors associated with IE in KTRs. We performed a retrospective case/control study which included patients from two centers. First episodes of definite or possible IE (Duke criteria) in adult KTRs from January 2010 to December 2018 were included, as well as two controls per case, and followed until 31 December 2019. Clinical, biological, and microbiological data and the outcome were collected. Survival was studied using the Kaplan-Meier method. Finally, we searched for factors associated with the onset of IE in KTRs by the comparison of cases and controls. Seventeen cases and 34 controls were included. IE was diagnosed after a mean delay of 78 months after KT, mostly on native valves of the left heart only. Pathogens of digestive origin were most frequently involved (six Enterococcus spp, three Streptococcus gallolyticus, and one Escherichia coli), followed by Staphylococci (three cases of S. aureus and S. epidermidis each). Among the risk factors evaluated, age, vascular nephropathy, and elevated calcineurin inhibitor through levels were significantly associated with the occurrence of IE in our study. Patient and death-censored graft survival were greatly diminished five years after IE, compared to controls being 50.3% vs. 80.6% (p < 0.003) and 29.7% vs. 87.5% (p < 0.002), respectively. IE in KTRs is a disease that carries significant risks both for the survival of the patient and the transplant.

RESUMEN

Importance: There is evidence of central nervous system impairments associated with coronavirus disease 2019 (COVID-19) infection, including encephalopathy. Multimodal monitoring of patients with COVID-19 may delineate the specific features of COVID-19-related encephalopathy and guide clinical management. Objectives: To investigate clinical, biological, and brain magnetic resonance imaging (MRI) findings in association with electroencephalographic (EEG) features for patients with COVID-19, and to better refine the features of COVID-19-related encephalopathy. Design, Setting, and Participants: This retrospective cohort study conducted in Pitié-Salpêtrière Hospital, Paris, France, enrolled 78 hospitalized adults who received a diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-Cov2) and underwent EEG between March 30 and June 11, 2020. Exposures: Detection of SARS-CoV-2 from a nasopharyngeal specimen using a reverse transcription-polymerase chain reaction assay or, in the case of associated pneumonia, on a computed tomography scan of the chest. Main Outcomes and Measures: Data on the clinical and paraclinical features of the 78 patients with COVID-19 were retrieved from electronic patient records. Results: Of 644 patients who were hospitalized for COVID-19, 78 (57 men [73%]; mean [SD] age, 61 [12] years) underwent EEG. The main indications for EEG were delirium, seizure-like events, and delayed awakening in the intensive care unit after stopping treatment with sedatives. Sixty-nine patients showed pathologic EEG findings, including metabolic-toxic encephalopathy features, frontal abnormalities, periodic discharges, and epileptic activities. Of 57 patients who underwent brain MRI, 41 showed abnormalities, including perfusion abnormalities, acute ischemic lesions, multiple microhemorrhages, and white matter-enhancing lesions. Fifty-five patients showed biological abnormalities, including dysnatremia, kidney failure, and liver dysfunction, the same day as the EEG. The results of cerebrospinal fluid analysis were negative for SARS-Cov-2 for all tested patients. Nine patients who had no identifiable cause of brain injury outside COVID-19 were further isolated; their brain injury was defined as COVID-19-related encephalopathy. They represented 1% (9 of 644) of patients with COVID-19 requiring hospitalization. Six of these 9 patients had movement disorders, 7 had frontal syndrome, 4 had brainstem impairment, 4 had periodic EEG discharges, and 3 had MRI white matter-enhancing lesions. Conclusions and Relevance: The results from this cohort of patients hospitalized with COVID-19 suggest there are clinical, EEG, and MRI patterns that could delineate specific COVID-19-related encephalopathy and guide treatment strategy.

RESUMEN

UNLABELLED: Alcohol increases reactive oxygen species (ROS) formation in hepatocyte mitochondria and by reduced nicotinamide adenine dinucleotide phosphate oxidases and myeloperoxidase (MPO) in Kupffer cells and liver-infiltrating neutrophils. Manganese superoxide dismutase (MnSOD) converts superoxide anion into hydrogen peroxide, which, unless detoxified by glutathione peroxidase or catalase (CAT), can form the hydroxyl radical with iron. Our aim was to determine whether Ala16Val-superoxide dismutase 2 (SOD2), G-463A-MPO, or T-262C-CAT dimorphisms modulate the risks of hepatocellular carcinoma (HCC) and death in alcoholic cirrhosis. Genotypes and the hepatic iron score were assessed in 190 prospectively followed patients with alcoholic cirrhosis. During follow-up (61.1 +/- 2.7 months), 51 patients developed HCC, and 71 died. The T-262C-CAT dimorphism did not modify hepatic iron, HCC, or death. The GG-MPO genotype did not modify iron but increased the risks of HCC and death. The hazard ratio (HR) was 4.7 (2.1-10.1) for HCC and 3.6 (1.9-6.7) for death. Carriage of one or two Ala-SOD2 allele(s) was associated with higher liver iron scores and higher risks of HCC and death. The 5-year incidence of HCC was 34.4% in patients with both the GG-MPO genotype and one or two Ala-SOD2 alleles, 5.1% in patients with only one of these two traits, and 0% in patients with none of these traits. Corresponding 5-year death rates were 37.6%, 11.6%, and 5%. CONCLUSION: The combination of the GG-MPO genotype (leading to high MPO expression) and at least one Ala-SOD2 allele (associated with high liver iron score) markedly increased the risks of HCC occurrence and death in patients with alcoholic cirrhosis.

RESUMEN

BACKGROUND: Unplanned transfer to an ICU within 48 hours of admission from the emergency department (ED) can be considered an adverse event. Screening at risk for such an event is a challenge for ED staff. Our purpose was to identify the clinical and biological variables which may be identified in the ED setting and can predict short-term unplanned secondary transfer to the intensive care setting. METHODS: This was a three-year retrospective case controlled monocentric study. The cases were patients transferred to a medical ICU within 48 hours of admission to the general wards from the ED. Each case was matched to two controls (patients not transferred to the ICU) based on age, gender, year of admission, and hospital unit. A conditional logistic regression was performed. RESULTS: Three hundred nineteen patients, including 107 cases and 212 controls, were studied. Community-acquired pneumonia (CAP) was the most frequent diagnosis (23% of cases) followed by sepsis (16%). We identified six predictive factors of an unplanned short-term transfer to the ICU. Former smoking status, fever between 38°C and 40°C, dyspnea as the chief complaint in the ED, a lower MEDS score, an elevated acute physiology age chronic health evaluation score, and the ordering of an arterial blood gas each correlate with secondary transfer to an intensive care setting. CONCLUSION: We report a higher risk of short-term unscheduled ICU transfer in patients meeting these criteria. These patients should be closely monitored and frequently re-evaluated before being transferred to a general ward.

RESUMEN

BACKGROUND & AIMS: The influence of HFE gene mutations and liver iron overload on hepatocellular carcinoma (HCC) occurrence in patients with cirrhosis is subjected to controversial results. The aim of this work was to clarify this influence in a large cohort of prospectively followed-up cirrhotic patients classified according to the cause of their liver disease. METHODS: Three hundred one consecutive cirrhotic patients (162 alcoholics and 139 HCV-infected patients) were included at time of diagnosis of cirrhosis and followed-up. Liver iron overload on initial biopsy according to modified Deugnier's score and C282Y/H63D HFE gene mutations were assessed. RESULTS: In patients with alcoholic cirrhosis (mean iron score, 2.0 +/- 3.0; mean time of follow-up, 66.1 +/- 45.1 months), 40 (24.6%) developed HCC. Thirteen (8.02%) were heterozygotes for C282Y HFE gene mutation and had higher hepatic iron scores (3.6 +/- 3.8 vs 1.9 +/- 2.8, respectively, P = .05). In univariate analysis, liver iron overload as a continuous variable (HR, 1.23 [1.13-1.34], P < .001) or in binary coding with an optimal threshold of iron score >/=2.0 (HR, 4.1 [2.1-7.3], P < .0001) and C282Y mutation carriage (HR, 2.7 [1.2-6.3], P = .01) were risk factors for HCC. In multivariate analysis, liver iron and C282Y mutation carriage remained independent risk factors for HCC. In patients with HCV-related cirrhosis (C282Y mutation carriage, 17 [12.23%]; mean liver iron score, 0.9 +/- 1.9; mean time of follow-up, 85.5 +/- 42.1 months; HCC, 63 [45.32%] patients), C282Y mutation carriage and liver iron were not associated with HCC occurrence. CONCLUSIONS: Liver iron overload and C282Y mutation are associated with a higher risk of HCC in patients with alcoholic but not HCV-related cirrhosis.

RESUMEN

AIM: To explore the influence of polymorphisms in genes encoding for the chemokines Stromal cell-Derived Factor-1 (SDF-1)/CXCL12 and Monocyte Chemotactic Protein-1 (MCP-1)/CCL2, or for the chemokine receptor CCR5 on the risks of liver-related death and hepatocellular carcinoma (HCC) occurrence in hepatitis C virus (HCV)-infected patients. METHODS: SDF-1 3'A, MCP-1 (-2518) and CCR5-Delta32 polymorphisms, SDF-1 alpha, Regulated upon Activation Normal T cells Expressed and Secreted (RANTES)/CCL5 and MCP-1 serum levels were determined in 120 HCV-infected patients, included at time of cirrhosis diagnosis and prospectively followed-up. RESULTS: During follow-up, 23/120 (19.1%) patients died and 47/120 (39.1%) developed HCC. Carriers and noncarriers of each genetic marker had similar baseline characteristics estimating the severity of liver disease. The occurrence of death or HCC during follow-up was similar among carriers and noncarriers of each polymorphism. There was no association between the carriage of mutated alleles and chemokine serum levels and the latter were not associated with the risks of death or HCC. CONCLUSION: This study suggests the lack of association of SDF-1 3'A, MCP-1 (-2518), CCR5-Delta32 polymorphisms with death and HCC occurrence in cirrhotic HCV-infected patients.

RESUMEN

BACKGROUND: many studies have identified long-term care facilities (LTCFs) as reservoirs of patients carrying methicillin-resistant Staphylococcus aureus (MRSA). However, few data about the mechanisms of MRSA diffusion in these settings are available. OBJECTIVES: the purpose of our study was to suggest hypothesis on the possible ways of MRSA transmission to residents in or outside a LTCF. METHODS: data concerning patients on the day of the survey and within the preceding year were collected. Multivariate analysis was performed by logistic regression to identify characteristics associated with MRSA carriage. MRSA strains were analysed by pulsed-field gel electrophoresis (PFGE) and the relatedness between DNA patterns was studied with Gel Compar software. RESULTS: the prevalence of MRSA carriage was 37.6%. Treatment with fluoroquinolones or third-generation cephalosporins [odds ratio (OR) = 12.07; 95% confidence interval (CI) = 5.90-24.7], treatment with other antimicrobial agents (OR = 4.40; 95% CI = 2.43-7.97), at least one medical imaging session (OR = 5.08; 95% CI = 2.66-9.69) within the 12 preceding months, and the presence of a subcutaneous catheter on the day of the survey (OR = 3.09; 95% CI = 1.87-5.10) were independently associated with MRSA carriage. Twenty-eight of the 38 strains tested were clustered in two major groups. In each of these groups, strains had at least a 90% relatedness. These strains were isolated in patients hospitalised in different areas of the LTCF. CONCLUSION: we identified that both molecular and epidemiological arguments support the hypothesis of the possibility of MRSA cross-transmission inside the LTCF. Further studies are needed to confirm and explain the association identified between MRSA carriage and medical imaging.
