Risk factors for the in‑hospital and 1‑year mortality of elderly patients hospitalized due to COVID‑19‑related pneumonia. Exp Ther Med 2024; 27:22. [PMID: 38125348 PMCID: PMC10728907 DOI: 10.3892/etm.2023.12310] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Accepted: 11/09/2023] [Indexed: 12/23/2023] Open
Abstract
Coronavirus disease 2019 (COVID-19) is characterized by poor outcomes and a high mortality rate, particularly among elderly patients. Since the beginning of the pandemic, an older age has been recognized as a critical risk factor for disease severity, with increasing mortality rates in each decade of life. This phenomenon may be a consequence of a poor previous health status, with a higher prevalence of pre-existing comorbidities and a higher degree of frailty. The majority of studies on the outcomes and risk factors of elderly patients refer to the first waves of the pandemic and the predictors of in-hospital mortality in these patients. The aim of the present study was to provide a detailed description of the clinical characteristics and management of a cohort of elderly patients (≥65 years of age) who were hospitalized with COVID-19-related pneumonia in all phases of the pandemic, presenting their outcomes, and investigating predictors of in-hospital and out-of-hospital mortality over a period of 1 year in this particularly vulnerable population. A total of 1,124 elderly patients (603 males, 53.7%) with a mean age of 78.51±7.42 years and a median Charlson comorbidity index (CCI) of 5 were included in the study. Of these patients, 104 (9.3%) were hospitalized during the period of prevalence of the original strain Wuhan, 385 (34.3%) were hospitalized during the period of prevalence of the Alpha variant, 221 (19.7%) were hospitalized during the period of prevalence of the Delta variant, and 414 (36.8%) were hospitalized during the period of prevalence of the Omicron variant. Overall, the in-hospital mortality rate was 33.4% (375 patients), and the 1-year mortality rate was 44.7% (502 patients). The majority of patients had not been vaccinated or had not completed full vaccination against severe acute respiratory syndrome coronavirus-2 (843 patients, 75%), given the period of infection. Age, immature granulocytes, lactate dehydrogenase (LDH) levels, ferritin levels, chest X-ray score, as well as the absence of full vaccination, cough and fatigue, were statistically significantly and independently associated with in-hospital mortality, while age, LDH levels, ferritin levels, alanine aminotransferase levels, CCI, chest X-ray score, the absence of cough and fatigue, and a history of dementia were statistically significantly and independently associated with 1-year mortality. On the whole, the present study demonstrates that both the in-hospital mortality and 1-year mortality rates of elderly patients hospitalized due to COVID-19-related pneumonia are high.

Early 3‑day course of remdesivir for the prevention of the progression to severe COVID‑19 in the elderly: A single‑centre, real‑life cohort study. Exp Ther Med 2023; 26:462. [PMID: 37664680 PMCID: PMC10469144 DOI: 10.3892/etm.2023.12161] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Accepted: 07/31/2023] [Indexed: 09/05/2023] Open
Abstract
Remdesivir, a viral RNA polymerase inhibitor, has constituted a key component of therapeutic regimens against the pandemic caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Originally approved for administration in hospitalized patients, remdesivir leads to improved outcomes in patients with moderate to severe coronavirus disease 2019 (COVID-19). After proving to be effective in hospitalized patients, its use gained approval in early-stage disease for symptomatic outpatients who are at a high risk of progression to severe disease. The present study is a real-life prospective cohort study involving 143 elderly non-hospitalized patients with SARS-CoV-2 (≥65 years of age) who attended the emergency department of the authors' hospital seeking care for COVID-19 symptoms appearing within the prior 7 days. Eligible patients received intravenous remdesivir at a dose of 200 mg on the first day and 100 mg on days 2 and 3. The efficacy endpoints were set as the need for COVID-19-related hospitalization and all-cause mortality in the following 28 days. A total of 143 patients participated in the study. Of these patients, 118 (82.5%) patients were vaccinated with at least two doses. All patients enrolled completed the 3-day course, with a total of 6 out of 143 patients (4.2%) having a COVID-19-related hospitalization by day 28, and 5 patients (3.5%) succumbing to the disease within the study period. In the univariate Cox regression analysis, the neutrophil-to-lymphocyte ratio and haematological malignancy were identified as predictors of progression to severe disease, and albumin levels, the C-reactive protein-to-albumin ratio (CAR) and haematological malignancy were identified as predictors of 28-day mortality. On the whole, the findings of the present study demonstrated that among the elderly outpatients, a 3-day course of intravenous remdesivir was associated with favourable outcomes.

Predictors of COVID‑19‑associated mortality among hospitalized elderly patients with dementia. Exp Ther Med 2023; 26:395. [PMID: 37456163 PMCID: PMC10347294 DOI: 10.3892/etm.2023.12094] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Accepted: 06/23/2023] [Indexed: 07/18/2023] Open
Abstract
The mortality of elderly patients with dementia hospitalized with coronavirus disease 2019 (COVID-19)-associated pneumonia is high. The mortality rate of these patients continues to be high following their discharge. However, data on the outcomes of these patients in all phases of the pandemic are limited. The aim of the present study was to examine the clinical characteristics and the in-hospital and 90-day mortality rates of elderly patients with dementia hospitalized due to COVID-19-associated pneumonia during all phases of the pandemic. During the time period between February 15, 2021 to July 15, 2022, 105 elderly patients (≥65 years old) with dementia of various etiologies were hospitalized due to COVID-19-associated pneumonia. The patient characteristics and in-hospital outcomes within 90 days of admission were recorded. The mean age of the patients was 84.03±7.61 years and 60 (57.1%) patients were females. A total of 52 (49.5%) patients were hospitalized during the omicron variant period, 27 (25.7%) were fully vaccinated (three doses) and 38 (36.2%) patients succumbed during their hospitalization. In total, 52 (49.5%) patients succumbed within the first 90 days of admission. According to the univariate regression analysis, the omicron variant [hazard ratio (HR), 2.126; 95% confidence interval (CI), 1.073-4.213; P=0.031] and the absence of full vaccination (HR, 6.231; 95% CI, 1.500-25.87; P=0.012) were associated with a higher in-hospital mortality. In the multivariate regression analysis, only the absence of complete vaccination was an independent predictor of mortality (HR, 5.182; 95% CI, 1.205-22.28; P=0.027). According to the univariate regression analysis, age (HR, 1.045; 95% CI, 1.006-1.085; P=0.023) and the lack of complete vaccination (HR, 3.254; 95% CI, 1.294-8.181; P=0.012) were associated with 90-day mortality; in addition, by multivariate regression analysis, age (HR, 1.047; 95% CI, 1.007-1.048; P=0.021) and the absence of full vaccination (HR, 3.286; 95% CI, 1.307-8.265; P=0.011) exhibited an independent association with the 90-day mortality rate. Based on the findings presented herein, the in-hospital and 90-day mortality rates of elderly patients with dementia and COVID-19-associated pneumonia is high. An older age and the lack of complete vaccination are independently associated with poor outcomes.

Effectiveness of Oral Nirmatrelvir/Ritonavir vs. Intravenous Three-Day Remdesivir in Preventing Progression to Severe COVID-19: A Single-Center, Prospective, Comparative, Real-Life Study. Viruses 2023; 15:1515. [PMID: 37515201 PMCID: PMC10383489 DOI: 10.3390/v15071515] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 06/28/2023] [Accepted: 07/06/2023] [Indexed: 07/30/2023] Open
Abstract
BACKGROUND Nirmatrelvir/ritonavir (NMV/r) and three-day course remdesivir (3RDV) have been approved as early treatments for COVID-19 outpatients not requiring supplemental oxygen. Real-life data on the efficacy of antivirals among immunocompromised patients or directly comparing their effectiveness in preventing hospitalization and/or death are scarce. METHODS Prospective, observational study conducted in a tertiary care hospital, from 1 January 2022 until 15 March 2023, during the prevalence of the Omicron variant. Inverse probability of treatment weighting (IPTW) was used to account for differences between treatment groups. RESULTS We included 521, mainly immunocompromised (56%), patients in our analysis; 356 (68.3%) received 3RDV and 165 (31.7%) NMV/r. Overall, 15/521 (2.9%) patients met the primary end-point of hospitalization at 30 days (3RDV arm: 10/356, 2.8% vs. NMV/r arm: 5/165, 3%, p = 1). On IPTW-adjusted univariable analysis, the choice of treatment did not affect outcomes. In multivariable logistic regression analysis, we found that one (OR 0.26, 95%CI 0.07-0.99, p = 0.049) or two (OR 0.06, 95%CI 0.01-0.55, p = 0.014) vaccine booster shots reduced the risk for adverse outcomes. CONCLUSION In our patient population of high-risk, mainly immunocompromised, vaccinated patients during the prevalence of the Omicron variant, NMV/r and 3RDV were equally effective early treatments for the prevention of hospitalization and/or death.

Characteristics and outcomes of elderly patients with Parkinson's disease hospitalized due to COVID‑19‑associated pneumonia. MEDICINE INTERNATIONAL 2023; 3:34. [PMID: 37448768 PMCID: PMC10336924 DOI: 10.3892/mi.2023.94] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Accepted: 07/03/2023] [Indexed: 07/15/2023]
Abstract
Patients with Parkinson's disease (PD) and coronavirus disease 2019 (COVID-19)-associated pneumonia present, according to the literature, high mortality rates due to the nature of the disease, advanced age, and underlying diseases. Most available studies, however, refer to the first waves of the pandemic. The aim of the present study was to investigate the clinical characteristics and outcomes of elderly patients (≥65 years old) with PD hospitalized with COVID-19-associated pneumonia during the period of prevalence of various severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants, as well as to determine possible prognostic factors for poor outcomes. During the period from February 15, 2021, to July 15, 2022, 1,144 elderly patients with COVID-19 pneumonia were hospitalized. Age, sex, Charlson comorbidity index, vaccination status against SARS-CoV-2, and admission laboratory parameters were recorded for all patients. A total of 36 (3.1%) patients with PD were hospitalized due to COVID-19-associated pneumonia (18 males, 50%). The mean age of the patients was 82.72±8.18 years. In total, 8 patients (22.2%) were hospitalized during the period of alpha variant predominance, 3 patients (8.3%) during the period of delta variant predominance, and 25 patients (69.4%) during the omicron variant predominance period. Of note, 16 patients (44.4%) were vaccinated with at least two doses. In addition, 17 (47.2%) patients succumbed to the disease. Between the patients who survived and those who succumbed, a statistically significant difference was only found in the mean value of albumin (37.48±6.02 vs. 31.97±5.34 g/l, P=0.019). In particular, as shown by receiver operating characteristic curve analysis, albumin exhibited a satisfactory predictive ability for mortality (area under the curve, 0.780; P=0.013) with an albumin value ≤37.7 g/l being able to predict mortality with 85.7% sensitivity and 54.8% specificity. Overall, the findings of the present study indicate that mortality among elderly patients with PD hospitalized with COVID-19-associated pneumonia was high in all phases of the pandemic. A low albumin value, not only as an indicator of the immune status, but also of the nutritional status, is a predictor of adverse outcomes.

The association of insulin resistance measured through the estimated glucose disposal rate with predictors of micro-and macrovascular complications in patients with type 1 diabetes. Prim Care Diabetes 2022; 16:837-843. [PMID: 36272914 DOI: 10.1016/j.pcd.2022.10.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2022] [Revised: 10/04/2022] [Accepted: 10/10/2022] [Indexed: 11/17/2022]
Abstract
BACKGROUND AND AIM Insulin resistance (IR) is associated with a higher rate of type 1 diabetes (T1D) complications. We aimed to examine the relationship between estimated glucose disposal rate (eGDR), a readily available marker of IR in clinical practice and early predictor biomarkers of macrovascular and microvascular complications in patients with T1D. DESIGN A cross-sectional study. METHODS A total of 165 consecutive patients with T1D free of cardiovascular, eye, and renal complications were included in the study from 2016 to 2020. Participants were characterized as insulin resistant if their eGDR value was ≤ 8 mg/kg/min. Pulse wave velocity (PWV) and global longitudinal strain (GLS) were used as surrogates for subclinical atherosclerosis and left ventricular systolic dysfunction (LVSD), respectively. Four previously standardized tests based on the calculation of heart rate variability (HRV) were used to evaluate subclinical cardiac autonomic neuropathy (CAN). Early nephropathy was assessed by assessing urinary albumin to creatinine ratio (ACR). RESULTS The population sample (n = 165) included a majority of female patients (63%) and had a median age of 32 years (24-43), median disease duration of 14 years ( ± 9.5-21.5), a median BMI value of 23.7 kg/m2 (21.4-26.6), an HbA1C of 7.2% (6.7-8.2) and median eGDR (lower values indicate higher insulin resistance) of 9.2 mg/kg/min (8.2-9.9), while 21.8% (n = 36) of the participants were characterized as insulin resistant. After adjustment for age, gender, and the duration of diabetes, the presence of IR was significantly associated with higher prevalence of subclinical atherosclerosis (OR:2.59, 95% CI: 1.06-6.30, p = 0.036), CAN (OR:3.07, 95% CI: 1.02-9.32, p = 0.047) and subclinical LVSD (OR: 4.9, 95% CI: 1.94-12.79, p = 0.001). No association was shown with ACR. CONCLUSIONS In patients with T1D, insulin resistance, as measured by eGDR, correlates well with early CVD predictors and CAN. These associations appear independent of the effects of gender, aging, and disease duration.

Abstract
Coronavirus disease 2019 (COVID-19) is a systemic illness with an increased host inflammatory response that affects multiple extra-pulmonary organs, including the gastrointestinal tract. Abnormalities in liver biochemistry have been observed in a significant proportion of patients with COVID-19 upon admission, and this proportion increases with hospitalization. These abnormalities are typically manifested as elevations in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels, with less frequently detected elevations in the levels of cholestatic enzymes. Elevated aminotransaminase levels have been linked to an increased risk of mortality and complications, indicating the severity of COVID-19 infection. The present study evaluated the prevalence and the baseline factors associated with the development of acute hepatitis (ΑΗ), liver injury (LI) and associated patterns, as well as the presence of abnormalities in the levels of aminotransferases at discharge in the same cohort. For this purpose, 1,304 patients with confirmed COVID-19 infection were enrolled in the study. According to the results obtained, AST levels at baseline were the only independent factor for AH during hospital stay, while AST, alkaline phosphatase and ferritin levels were independent baseline factors for the development of LI. The patients with hepatocellular, compared to those with cholestatic LI, exhibited similar survival rates, as well as similarities in the development of acute kidney injury and the need for oxygen via high-flow nasal cannula and/or mechanical ventilation. In addition, age and ALT were independent risk factors for persistent abnormal values of AST and ALT at discharge.

Abstract
PURPOSE OF REVIEW This narrative review appraises research data on the potentially harmful effect of obesity and insulin resistance (IR) co-existence with type 1 diabetes mellitus (T1DM)-related cardiovascular (CVD) complications and evaluates possible therapeutic options. RECENT FINDINGS Obesity and IR have increasingly been emerging in patients with T1DM. Genetic, epigenetic factors, and subcutaneous insulin administration are implicated in the pathogenesis of this coexistence. Accumulating evidence implies that the concomitant presence of obesity and IR is an independent predictor of worse CVD outcomes. The prevalence of obesity and IR has increased in patients with T1DM. This increase can be partly attributed to general population trends but, additionally, to iatrogenic weight gain caused by insulin treatment. This association might be the missing link explaining the excess CVD burden observed in patients with T1DM despite optimal glycemic control. Data on newer agents for type 2 diabetes mellitus (T2DM) treatment are unraveling novel ways to challenge this aggravating coexistence.

A Simple Prognostic Score for Critical COVID-19 Derived from Patients without Comorbidities Performs Well in Unselected Patients. J Clin Med 2022; 11:jcm11071810. [PMID: 35407418 PMCID: PMC8999885 DOI: 10.3390/jcm11071810] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Revised: 03/18/2022] [Accepted: 03/23/2022] [Indexed: 12/15/2022] Open
Abstract
We aimed to search for laboratory predictors of critical COVID-19 in consecutive adults admitted in an academic center between 16 September 2020−20 December 2021. Patients were uniformly treated with low-molecular-weight heparin, and dexamethasone plus remdesivir when SpO2 < 94%. Among consecutive unvaccinated patients without underlying medical conditions (n = 241, 49 year-old median, 71% males), 22 (9.1%) developed critical disease and 2 died (0.8%). White-blood-cell counts, neutrophils, neutrophil-to-lymphocyte ratio, CRP, fibrinogen, ferritin, LDH and γ-GT at admission were each univariably associated with critical disease. ROC-defined cutoffs revealed that CRP > 61.8 mg/L, fibrinogen > 616.5 mg/dL and LDH > 380.5 U/L were each associated with critical disease development, independently of age, sex and days from symptom-onset. A score combining higher-than-cutoff CRP (0/2), LDH (0/1) and fibrinogen (0/1) predicted critical disease (AUC: 0.873, 95% CI: 0.820−0.926). This score performed well in an unselected patient cohort (n = 1228, 100% unvaccinated) predominantly infected by the alpha variant (AUC: 0.718, 95% CI: 0.683−0.753), as well as in a mixed cohort (n = 527, 65% unvaccinated) predominantly infected by the delta variant (AUC: 0.708, 95% CI: 0.656−0.760). Therefore, we propose that a combination of standard biomarkers of acute inflammatory response, cell death and hypercoagulability reflects the severity of COVID-19 per se independently of comorbidities, age and sex, being of value for risk stratification in unselected patients.

Abstract
Background Abnormalities in aminotransferases are frequently observed in hospitalized COVID-19 patients, but their clinical impact is poorly characterized. Methods A total of 1046 patients hospitalized to the non-intensive care unit ward with documented COVID-19 were included retrospectively. Demographic, clinical and laboratory characteristics on admission and during hospital stay, including the presence of liver injury (LI), defined as aspartate aminotransferase (AST) >200 IU/L, were recorded. Results On admission, 363 (34.7%) and 269 (25.7%) patients had abnormal AST and ALT values (i.e., >40 IU/L), respectively, while during hospitalization 53 (5%) patients fulfilled the criteria for LI. In multivariate logistic regression analysis, AST (odds ratio [OR] 1.023, 95% confidence interval [CI] 1.016-1.029; P<0.001), and ferritin (OR 1.01, 95%CI 1.001-1.02; P<0.001) were the baseline factors independently associated with the development of LI during hospital stay. One hundred twenty-three (11.7%) patients died during hospitalization. The independent variables associated with mortality were: age (hazard ratio [HR] 1.043, 95%CI 1.029-1.056; P<0.001), ferritin (HR 1.1, 95%CI 1.05-1.2; P<0.001), platelets (HR 0.996, 95%CI 0.994-0.999; P=0.003), and administration of remdesivir (HR 0.50, 95%CI 0.30-0.85; P=0.009). The patients with abnormal baseline AST (i.e., >40 IU/L), compared to those with normal AST values, had worse outcomes (log rank test: 8.8, P=0.003). Conclusions Elevated aminotransferases are commonly seen in COVID-19 patients. They possibly reflect disease severity and may be associated with in-hospital mortality.

The effectiveness of a community-based, type 2 diabetes prevention programme on health-related quality of life. The DE-PLAN study. PLoS One 2019; 14:e0221467. [PMID: 31603914 PMCID: PMC6788719 DOI: 10.1371/journal.pone.0221467] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2018] [Accepted: 08/05/2019] [Indexed: 01/10/2023] Open
Abstract
Background and aims The DE-PLAN was a European multicenter study, with the primary objective of testing whether a community-based lifestyle modification programme could serve as a means of primary prevention for type 2 diabetes (T2D) in high-risk individuals (based on the FINDRISC questionnaire). The aim of this study was to examine the impact of a 1-year community-based lifestyle intervention on health-related quality of life (HRQOL) in individuals from four participating European centers (Athens, Barcelona, Krakow, Kaunas), through a post-hoc analysis. Materials and methods Each center was allowed to implement different intervention strategies specifically tailored to the needs of their corresponding population sample. Before and after the intervention, participants underwent clinical evaluation, anthropometric measurements, an oral glucose tolerance test and lipid profile measurements. Health-related quality of life was assessed using the validated HRQOL-15D questionnaire. A difference of ±0.015 in the 15D questionnaire score was set as the threshold of clinically meaningful change. Results Data from 786 participants (67% females, mean age 59.7±9.4 years, BMI 31.5±4.5 kg/m2) with complete data regarding the HRQOL were analyzed (Athens: 104, Barcelona: 434, Krakow: 175, Kaunas: 70). After 1 year, a significant overall improvement in HRQOL was shown, as depicted by a change of 15D score from baseline value (0.88±0.9) to post-intervention (0.90±0.87, P<0.001), achieving the threshold of clinically meaningful change. A significant weight reduction was also observed (-0.8±4.0 kg, P<0.001). In multivariate analysis, improvement in HRQOL was independently associated with lower 15D score at baseline (P<0.001) and self-reported increase in overall exercise time (P<0.001) as assessed through specifically designed trial questionnaires. Conclusion A community-based lifestyle intervention programme aiming at T2D prevention, applied on a heterogeneous population and with varied methods, was shown to improve overall health-related quality of life to a clinically meaningful degree.

Preliminary qualification of a novel, hypoxic-based radiologic signature for trans-arterial chemoembolization in hepatocellular carcinoma. BMC Cancer 2018; 18:211. [PMID: 29463228 PMCID: PMC5819666 DOI: 10.1186/s12885-018-4120-4] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2016] [Accepted: 02/12/2018] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Survival advantage following trans-arterial chemoembolization (TACE) is variable in patients with hepatocellular carcinoma (HCC). We combined pre-TACE radiologic features to derive a novel prognostic signature in HCC. METHODS A multi-institutional dataset of 98 patients was generated from two retrospective cohorts from United Kingdom (65%) and Italy (36%). The prognostic impact of a number baseline imaging parameters was assessed and factors significant on univariate analysis were combined to create a novel radiologic signature on multivariable analyses predictive of overall survival (OS) following TACE. RESULTS Median OS was 15.4 months. Tumour size > 7 cm (p < 0.001), intra-tumour necrosis (ITN) (p = 0.02) and arterial ectatic neovascularisation (AEN) (p = 0.03) emerged as individual prognostic factors together with radiologic response (p < 0.001) and elevated alpha-fetoprotein (AFP) (p = 0.01). Combination of tumour size > 7 cm, ITN and AEN identified patients with poor prognosis (p < 0.001). CONCLUSIONS We identified a coherent signature based on commonly available imaging biomarkers likely to be reflective of differential patterns of relative hypoxia and neovascularisation. Large tumours displaying AEN and ITN are characterised by a shorter survival after TACE.

The Kings Score refines prognostic prediction in hepatocellular carcinoma: a novel application. Liver Int 2015; 35:2458-65. [PMID: 25845291 DOI: 10.1111/liv.12841] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2014] [Accepted: 03/20/2015] [Indexed: 12/13/2022]
Abstract
BACKGROUND & AIMS There are a number of prognostic scores in hepatocellular carcinoma (HCC), none of which is optimal in predicting overall survival (OS) in the individual patient, particularly in intermediate stage disease, where patients are not surgically treatable but may qualify for a wide range of palliative interventions. We evaluated the prognostic role of a biochemical algorithm, the Kings Score (KS), in the palliative setting of care. METHODS We used the algorithm [age x AST x INR]/platelet count to derive the KS. Full clinical data including Barcelona Clinic Liver Cancer (BCLC) stage were studied in a training set of 97 patients from the UK. Independent predictors of survival identified in multivariate analysis were validated in an independent cohort of 766 patients from Japan and Italy. RESULTS In both training and validation sets, KS was confirmed as an independent predictor of OS (P < 0.01). Ad-hoc subgroup analysis revealed the KS to be prognostic in the palliative setting, being able to subclassify patients presenting with intermediate and advanced disease according to BCLC criteria (P < 0.001). CONCLUSION The KS integrates into the BCLC system to improve prognostic substratification in the palliative setting of care. The KS may help reducing disease heterogeneity and refine treatment allocation in intermediate-advanced HCC.

Dynamic changes of the inflammation-based index predict mortality following chemoembolisation for hepatocellular carcinoma: a prospective study. Aliment Pharmacol Ther 2014; 40:1270-81. [PMID: 25327965 DOI: 10.1111/apt.12992] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/05/2014] [Revised: 08/27/2014] [Accepted: 09/28/2014] [Indexed: 12/19/2022]
Abstract
BACKGROUND Transarterial chemoembolisation (TACE) is a standard treatment for unresectable, intermediate stage hepatocellular carcinoma (HCC). Survival after TACE, however, can be highly variable, with no suitable biomarker predicting therapeutic outcome. The inflammation-based index (IBI) has previously been shown to independently predict overall survival (OS) in all stages of HCC. AIM To explore the prognostic ability of IBI as a predictor of survival after TACE. METHODS Baseline staging, biochemical and clinicopathological features including IBI were studied in a derivation set of 64 patients undergoing TACE for intermediate stage HCC. Dynamic changes in IBI before and after TACE were studied as predictors of survival using both a univariate and multivariate Cox regression model and further validated in two independent patient cohorts from Korea (n = 76) and Japan (n = 577). RESULTS Pre-treatment IBI predicted for OS in the derivation set (P = 0.001). Other univariate predictors of OS included radiological response to TACE (P < 0.001), pre-TACE CLIP score (P < 0.01), tumour diameter >5 cm (P = 0.05) and AFP ≥400 (P < 0.001). Normalisation of IBI post-TACE was associated with radiological response by mRECIST criteria and improved OS (P < 0.001). Normalisation of IBI remained a significant multivariate predictor of OS in both the derivation and validation sets (P < 0.001). CONCLUSIONS Normalisation of IBI after TACE is shown to be an independent predictor of survival and may be integrated into the retreatment criteria for repeat TACE in intermediate stage HCC. IBI and its dynamic changes after treatment are validated as a biomarker allowing the stratification of patients with a significant survival advantage following initial TACE.
