RESUMEN

BACKGROUND: Preventive management of tuberculosis in liver transplantation (LT) is challenging due to difficulties in detecting and treating latent tuberculosis infection (LTBI). The aim of this study was to analyze the safety and efficacy of a screening strategy for LTBI with the inclusion of moxifloxacin as treatment. METHODS: We performed a retrospective single-center study of all LTs performed between 2016 and 2019 with a minimum 4-year follow-up and a standardized protocol for the evaluation of LTBI. RESULTS: Pretransplant LTBI screening was performed in 191/218 (87.6%) patients, and LTBI was diagnosed in 27.2% of them. Treatment for LTBI was administered to 71.2% of the patients and included moxifloxacin in 75.6% of the cases. After a median follow-up of 1628 days, no cases of active tuberculosis occurred among moxifloxacin-treated patients. The incidence of Clostridioides difficile (0.46 vs. 0.38 episodes/1000 transplant-days; p =  .8) and multidrug-resistant gram-negative bacilli infection (0 vs. 0.7 episodes per 1000 transplant-days; p =  .08) were not significantly higher in comparison to patients who did not receive moxifloxacin. CONCLUSION: A preventive strategy based on systematic LTBI screening and moxifloxacin treatment before LT in positive cases appears safe and effective in preventing the development of tuberculosis in LT recipients. However, our findings are limited by a small sample size; thus, larger studies are required to validate our observations.

RESUMEN

The timing of the development of specific adaptive immunity after natural SARS-CoV-2 infection, and its relevance in clinical outcome, has not been characterized in depth. Description of the long-term maintenance of both cellular and humoral responses elicited by real-world anti-SARS-CoV-2 vaccination is still scarce. Here we aimed to understand the development of optimal protective responses after SARS-CoV-2 infection and vaccination. We performed an early, longitudinal study of S1-, M- and N-specific IFN-γ and IL-2 T cell immunity and anti-S total and neutralizing antibodies in 88 mild, moderate or severe acute COVID-19 patients. Moreover, SARS-CoV-2-specific adaptive immunity was also analysed in 234 COVID-19 recovered subjects, 28 uninfected BNT162b2-vaccinees and 30 uninfected healthy controls. Upon natural infection, cellular and humoral responses were early and coordinated in mild patients, while weak and inconsistent in severe patients. The S1-specific cellular response measured at hospital arrival was an independent predictive factor against severity. In COVID-19 recovered patients, four to seven months post-infection, cellular immunity was maintained but antibodies and neutralization capacity declined. Finally, a robust Th1-driven immune response was developed in uninfected BNT162b2-vaccinees. Three months post-vaccination, the cellular response was comparable, while the humoral response was consistently stronger, to that measured in COVID-19 recovered patients. Thus, measurement of both humoral and cellular responses provides information on prognosis and protection from infection, which may add value for individual and public health recommendations.

RESUMEN

The aim of this study was to analyze whether the coronavirus disease 2019 (COVID-19) vaccine reduces mortality in patients with moderate or severe COVID-19 disease requiring oxygen therapy. A retrospective cohort study, with data from 148 hospitals in both Spain (111 hospitals) and Argentina (37 hospitals), was conducted. We evaluated hospitalized patients for COVID-19 older than 18 years with oxygen requirements. Vaccine protection against death was assessed through a multivariable logistic regression and propensity score matching. We also performed a subgroup analysis according to vaccine type. The adjusted model was used to determine the population attributable risk. Between January 2020 and May 2022, we evaluated 21,479 COVID-19 hospitalized patients with oxygen requirements. Of these, 338 (1.5%) patients received a single dose of the COVID-19 vaccine and 379 (1.8%) were fully vaccinated. In vaccinated patients, mortality was 20.9% (95% confidence interval [CI]: 17.9-24), compared to 19.5% (95% CI: 19-20) in unvaccinated patients, resulting in a crude odds ratio (OR) of 1.07 (95% CI: 0.89-1.29; p = 0.41). However, after considering the multiple comorbidities in the vaccinated group, the adjusted OR was 0.73 (95% CI: 0.56-0.95; p = 0.02) with a population attributable risk reduction of 4.3% (95% CI: 1-5). The higher risk reduction for mortality was with messenger RNA (mRNA) BNT162b2 (Pfizer) (OR 0.37; 95% CI: 0.23-0.59; p < 0.01), ChAdOx1 nCoV-19 (AstraZeneca) (OR 0.42; 95% CI: 0.20-0.86; p = 0.02), and mRNA-1273 (Moderna) (OR 0.68; 95% CI: 0.41-1.12; p = 0.13), and lower with Gam-COVID-Vac (Sputnik) (OR 0.93; 95% CI: 0.6-1.45; p = 0.76). COVID-19 vaccines significantly reduce the probability of death in patients suffering from a moderate or severe disease (oxygen therapy).

RESUMEN

BACKGROUND: Respiratory failure (RF) is the most important complication of influenza virus infection. Its definition and incidence are heterogeneous in the literature. METHODS: This systematic review and meta-analysis aim to determine the incidence of and risk factors for RF in patients hospitalized with influenza. Electronic databases were searched for articles on RF in patients hospitalized for influenza infection up to December 2021 regardless of their geographical location. Observational and experimental studies were considered for inclusion, excluding case series. The Newcastle-Ottawa and Johanna Briggs scales were used for quality assessment. A random-effects meta-analysis was performed, followed by subgroup analyses according to, among others, presence/absence of pneumonia, RF definition, serotype and time period. PRISMA guidelines were followed for this review. RESULTS: Thirty-six studies were finally included in the meta-analysis. Overall, RF incidence was 24% (range 5%-85%, 95% confidence interval [95CI] 19%-31%). Significantly higher incidences of RF were found in patients with pneumonia (42%, 95CI 28%-57%, p = .006), when RF was defined as hypoxemia (58%, 95CI 31%-81%, p < .001), and during the 2009 pandemic (25%, 95CI 16%-36%) and postpandemic period (23%, 95CI 15%-34%, p = .01). No differences were found between human influenza serotypes. Assessment of risk factors associated with the development of RF was not possible due to their inconsistent and heterogeneous reporting. CONCLUSION: Respiratory failure is frequent in hospitalized influenza patients, especially in patients with pneumonia and since the 2009 pandemic, although its definition and reporting widely vary in the literature. This complicates its characterization and comparison between cohorts and with other respiratory viruses.

RESUMEN

BACKGROUND: Influenza viruses cause seasonal epidemics worldwide with a significant morbimortality burden. Clinical spectrum of Influenza is wide, being respiratory failure (RF) one of its most severe complications. This study aims to elaborate a clinical prediction rule of RF in hospitalized Influenza patients. METHODS: A prospective cohort study was conducted during two consecutive Influenza seasons (December 2016-March 2017 and December 2017-April 2018) including hospitalized adults with confirmed A or B Influenza infection. A prediction rule was derived using logistic regression and recursive partitioning, followed by internal cross-validation. External validation was performed on a retrospective cohort in a different hospital between December 2018 and May 2019. RESULTS: Overall, 707 patients were included in the derivation cohort and 285 in the validation cohort. RF rate was 6.8% and 11.6%, respectively. Chronic obstructive pulmonary disease, immunosuppression, radiological abnormalities, respiratory rate, lymphopenia, lactate dehydrogenase and C-reactive protein at admission were associated with RF. A four category-grouped seven point-score was derived including radiological abnormalities, lymphopenia, respiratory rate and lactate dehydrogenase. Final model area under the curve was 0.796 (0.714-0.877) in the derivation cohort and 0.773 (0.687-0.859) in the validation cohort (p < 0.001 in both cases). The predicted model showed an adequate fit with the observed results (Fisher's test p > 0.43). CONCLUSION: we present a simple, discriminating, well-calibrated rule for an early prediction of the development of RF in hospitalized Influenza patients, with proper performance in an external validation cohort. This tool can be helpful in patient's stratification during seasonal Influenza epidemics.

RESUMEN

BACKGROUND: The aim of the study was to analyze the clinical manifestations and outcome of the oldest old (people aged ≥85 years) who were admitted to the hospital with a confirmed influenza A virus infection in comparison with younger patients and to assess the role of inflammation in the outcome of influenza infection in this population. METHODS: This is an observational prospective study including all adult patients with influenza A virus infection hospitalized in a tertiary teaching hospital in Madrid, in 2 consecutive influenza seasons (2016-17 and 2017-18). RESULTS: Five hundred nine hospitalized patients with influenza A infection were included, of whom 117 (23%) were older than 85 years (median age: 89.3 ± 3.2). We compared the clinical characteristics and outcome with those of the rest of the population (median age: 72.8 ± 15.7). Overall, mortality was higher in older patients (10% vs. 4%; p = 0.03) with no differences in clinical presentation. Patients older than 85 years who ultimately died (12 out of 117) showed increased systemic inflammation expressed by higher levels of C-reactive protein (CRP) and ferritin compared to survivors who were discharged (odds ratio [OR] of CRP >20 mg/dL: 5.16, 95% confidence interval [CI]: 1.29-20.57, and OR of ferritin >500 mg: 4.3, 95% CI: 1.04-17.35). CONCLUSIONS: Patients aged 85 and older with influenza A virus infection presented a higher in-hospital mortality than younger subjects. CRP and ferritin levels were higher in the oldest old who died, suggesting that inflammation could play a key role in the outcome of this subset of patients.

RESUMEN

BACKGROUND: Invasive fungal infection, particularly intraabdominal candidiasis, exerts a negative impact on the outcome of pancreas transplant recipients (PTRs). Optimal antifungal prophylaxis in this context remains unclear. METHODS: We performed a single-centre retrospective study to compare the incidence of invasive candidiasis during the first 6 post-transplant months in a cohort of 218 PTRs over two periods in which different agents for antifungal prophylaxis were used: fluconazole (Fluco-Px) from March 1995 to June 2012, and micafungin followed by fluconazole (Mica-Px) from July 2012 to December 2018. RESULTS: A total of 152 and 66 PTRs received Fluco-Px and Mica-Px. Mean age was 39.7 ± 7.8 years, 56.4% (123/218) were males, and 85.3% (186/218) underwent simultaneous pancreas-kidney transplantation. Invasive candidiasis occurred in 21.7% (33/152) of PTRs under Fluco-Px compared to 24.2% (16/66) of those under Mica-Px (p-value = .681). Median time from transplantation to infection was 8 days (interquartile range [IQR]: 6-16) under Fluco-Px versus 6.5 (IQR: 3.3-15.8) under Mica-Px (p-value = .623). Non-albicans Candida species comprised 27.5% (11/40) and 25.0% (4/16) of episodes under Fluco-Px and Mica-Px respectively (p-value = .849). Surgical site infection was the most common form in both groups (82.5% [33/40] and 87.5% [14/16]; p-value = .954). Multivariable analysis identified cold ischaemia time of the pancreas and kidney grafts, surgical reintervention and insulin requirement after transplantation as risks factor for invasive candidiasis. CONCLUSION: This retrospective study did not reveal a significant benefit from the initial use of micafungin-based antifungal prophylaxis over fluconazole among PTRs in terms of invasive candidiasis.

RESUMEN

Coronavirus disease 2019 (COVID-19) can lead to a massive cytokine release. The use of the anti-interleukin-6 receptor monoclonal antibody tocilizumab (TCZ) has been proposed in this hyperinflammatory phase, although supporting evidence is limited. We retrospectively analyzed 88 consecutive patients with COVID-19 pneumonia that received at least one dose of intravenous TCZ in our institution between 16 and 27 March 2020. Clinical status from day 0 (first TCZ dose) through day 14 was assessed by a 6-point ordinal scale. The primary outcome was clinical improvement (hospital discharge and/or a decrease of ≥2 points on the 6-point scale) by day 7. Secondary outcomes included clinical improvement by day 14 and dynamics of vital signs and laboratory values. Rates of clinical improvement by days 7 and 14 were 44.3% (39/88) and 73.9% (65/88). Previous or concomitant receipt of subcutaneous interferon-ß (adjusted odds ratio [aOR]: 0.23; 95% confidence interval [CI]: 0.06-0.94; P = .041) and serum lactate dehydrogenase more than 450 U/L at day 0 (aOR: 0.25; 95% CI: 0.06-0.99; P = .048) were negatively associated with clinical improvement by day 7. All-cause mortality was 6.8% (6/88). Body temperature and respiratory and cardiac rates significantly decreased by day 1 compared to day 0. Lymphocyte count and pulse oximetry oxygen saturation/FiO2 ratio increased by days 3 and 5, whereas C-reactive protein levels dropped by day 2. There were no TCZ-attributable adverse events. In this observational single-center study, TCZ appeared to be useful and safe as immunomodulatory therapy for severe COVID-19 pneumonia.

RESUMEN

BACKGROUND: Age is a risk factor for COVID severity. Most studies performed in hospitalized patients with SARS-CoV2 infection have shown an over-representation of older patients and consequently few have properly defined COVID-19 in younger patients who require hospital admission. The aim of the present study was to analyze the clinical characteristics and risk factors for the development of respiratory failure among young (18 to 50 years) hospitalized patients with COVID-19. METHODS: This retrospective nationwide cohort study included hospitalized patients from 18 to 50 years old with confirmed COVID-19 between March 1, 2020, and July 2, 2020. All patient data were obtained from the SEMI-COVID Registry. Respiratory failure was defined as the ratio of partial pressure of arterial oxygen to fraction of inspired oxygen (PaO2/FiO2 ratio) ≤200 mmHg or the need for mechanical ventilation and/or high-flow nasal cannula or the presence of acute respiratory distress syndrome. RESULTS: During the recruitment period, 15,034 patients were included in the SEMI-COVID-19 Registry, of whom 2327 (15.4%) were younger than 50 years. Respiratory failure developed in 343 (14.7%), while mortality occurred in 2.3%. Patients with respiratory failure showed a higher incidence of major adverse cardiac events (44 (13%) vs 14 (0.8%), p<0.001), venous thrombosis (23 (6.7%) vs 14 (0.8%), p<0.001), mortality (43 (12.5%) vs 7 (0.4%), p<0.001), and longer hospital stay (15 (9-24) vs 6 (4-9), p<0.001), than the remaining patients. In multivariate analysis, variables associated with the development of respiratory failure were obesity (odds ratio (OR), 2.42; 95% confidence interval (95% CI), 1.71 to 3.43; p<0.0001), alcohol abuse (OR, 2.40; 95% CI, 1.26 to 4.58; p=0.0076), sleep apnea syndrome (SAHS) (OR, 2.22; 95% CI, 1.07 to 3.43; p=0.032), Charlson index ≥1 (OR, 1.77; 95% CI, 1.25 to 2.52; p=0.0013), fever (OR, 1.58; 95% CI, 1.13 to 2.22; p=0.0075), lymphocytes ≤1100 cells/µL (OR, 1.67; 95% CI, 1.18 to 2.37; p=0.0033), LDH >320 U/I (OR, 1.69; 95% CI, 1.18 to 2.42; p=0.0039), AST >35 mg/dL (OR, 1.74; 95% CI, 1.2 to 2.52; p=0.003), sodium <135 mmol/L (OR, 2.32; 95% CI, 1.24 to 4.33; p=0.0079), and C-reactive protein >8 mg/dL (OR, 2.42; 95% CI, 1.72 to 3.41; p<0.0001). CONCLUSIONS: Young patients with COVID-19 requiring hospital admission showed a notable incidence of respiratory failure. Obesity, SAHS, alcohol abuse, and certain laboratory parameters were independently associated with the development of this complication. Patients who suffered respiratory failure had a higher mortality and a higher incidence of major cardiac events, venous thrombosis, and hospital stay.

RESUMEN

The aim of our study was to elucidate if SARS-CoV-2 viral load on admission, measured by real-time reverse transcriptase-polymerase chain reaction (rRT-PCR) cycle threshold (Ct) value on nasopharyngeal samples, was a marker of disease severity. All hospitalized adult patients with a diagnosis of SARS-CoV-2 infection by rRT-PCR performed on a nasopharingeal sample from March 1 to March 18 in our institution were included. The study population was divided according to the Ct value obtained upon admission in patients with high viral load (Ct < 25), intermediate viral load (Ct: 25-30) and low viral load (Ct > 30). Demographic, clinical and laboratory variables of the different groups were analyzed to assess the influence of viral load on the development of respiratory failure during admission. Overall, 455 sequential patients were included. The median Ct value was 28 (IQR: 24-32). One hundred and thirty patients (28.6%) had a high viral load, 175 (38.5%) an intermediate viral load and 150 (33%) a low viral load. Advanced age, male sex, presence of cardiovascular disease and laboratory markers such as lactate dehydrogenase, lymphocyte count and C-reactive protein, as well as a high viral load on admission, were predictive of respiratory failure. A Ct value < 25 was associated with a higher risk of respiratory failure during admission (OR: 2.99, 95%IC: 1.57-5.69). SARS-CoV-2 viral load, measured through the Ct value on admission, is a valuable tool to predict the development of respiratory failure in COVID-19 inpatients.

RESUMEN

BACKGROUND: The impact of late-onset cytomegalovirus (CMV) infection (LOCI) on cardiac allograft vasculopathy (CAV) has yet to be established. METHODS: A retrospective study was performed for patients who had undergone heart transplantation (HT) between January 1995 and October 2017 to analyze epidemiology of LOCI (any positive level of CMV pp65 antigenemia or DNAemia after 100 days, without previous CMV replication) and its association with CAV. Our main hypothesis was that LOCI causes less direct and indirect effects compared to early onset infection (EOCI). RESULTS: Late-onset cytomegalovirus infection developed in 57 of 410 patients (13.9%) in a median time of 4.7 months post-transplant. CAV at 10 years was diagnosed in 31.6% of patients with LOCI, 34.6% with EOCI, and in 19.3% of CMV-uninfected patients. In the multivariate analysis, EOCI was an independent variable for developing CAV (HR 1.8, 95% CI 1.13-2.82, P = .01). Patients with LOCI showed a trend toward a higher risk of CAV, but the difference was not statistically significant (HR 1.7, 95% CI 0.95-3.08, P = .07). In the complementary log-log model, LOCI and EOCI had a similar CAV-free survival, and a higher probability of developing CAV than CMV-uninfected patients (P = .02). CONCLUSIONS: Cytomegalovirus infection after HT may result in the same long-term events regardless of its onset, with a higher risk of developing CAV at 10 years than patients without CMV.

RESUMEN

The clinical characteristics, management, and outcome of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) after solid organ transplant (SOT) remain unknown. We report our preliminary experience with 18 SOT (kidney [44.4%], liver [33.3%], and heart [22.2%]) recipients diagnosed with COVID-19 by March 23, 2020 at a tertiary-care center at Madrid. Median age at diagnosis was 71.0 ± 12.8 years, and the median interval since transplantation was 9.3 years. Fever (83.3%) and radiographic abnormalities in form of unilateral or bilateral/multifocal consolidations (72.2%) were the most common presentations. Lopinavir/ritonavir (usually associated with hydroxychloroquine) was used in 50.0% of patients and had to be prematurely discontinued in 2 of them. Other antiviral regimens included hydroxychloroquine monotherapy (27.8%) and interferon-ß (16.7%). As of April 4, the case-fatality rate was 27.8% (5/18). After a median follow-up of 18 days from symptom onset, 30.8% (4/13) of survivors developed progressive respiratory failure, 7.7% (1/13) showed stable clinical condition or improvement, and 61.5% (8/13) had been discharged home. C-reactive protein levels at various points were significantly higher among recipients who experienced unfavorable outcome. In conclusion, this frontline report suggests that SARS-CoV-2 infection has a severe course in SOT recipients.

RESUMEN

BACKGROUND: Which are the consequences of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in liver transplant (LT) recipients? METHODS: We attempted to address this question by reviewing our single-center experience during the first 2 months of the pandemics at a high incidence area. RESULTS: Nineteen adult patients (5 females) were diagnosed by May 5, 2020. Median age was 58 (range 55-72), and median follow-up since transplantation was 83 (range 20-183) months. Cough (84.2%), fever (57.9%), and dyspnea (47.4%) were the most common symptoms. Thirteen patients (68.4%) had pneumonia in x-ray/CT scan. Hydroxychloroquine was administered in 11 patients, associated with lopinavir/ritonavir and interferon ß in 2 cases each. Immunomodulatory therapy with tocilizumab was used in 2 patients. Immunosuppression (IS) was halted in one patient and modified in only other two due to potential drug interactions. Five (26.3%) patients were managed as outpatient. Two patients (10.5%) died, 10 (52.6%) were discharged home, and 2 (10.5%) were still hospitalized after a median follow-up of 41 days from the onset of symptoms. Baseline IS regimen remained unchanged in all surviving recipients, with good liver function. CONCLUSIONS: Our preliminary experience shows a broad spectrum of disease severity in LT patients with COVID-19, with a favorable outcome in most of them without needing to modify baseline IS.

RESUMEN

Real-life cohorts have shown that the effectiveness of all-oral, direct-acting antivirals (DAA) for HCV treatment is > 90%. We aimed to explore the predictive factors of DAA success in HIV coinfection. This is an observational prospective study within the cohort "VIH-DOC", Madrid, Spain. HIV/HCV-coinfected patients were included if they had been treated with DAAs between 9 January 2015 and 31 August 2016. The sustained virological response (SVR) was analysed in the intention-to-treat population. Binary logistic regression was used to study the impact of cirrhosis, anti-HCV therapy experience and the IL28B polymorphism on SVR, besides factors with a p value < 0.15 from the univariate analysis. DAA were prescribed to 423 patients. SVR was confirmed in 92.9%. The univariate analysis showed higher proportion of patients with SVR among those with DAA adherence ≥ 95% (difference + 10.3%, 95% CI 3.5-19.6) and a baseline CD4+ cell count ≥ 200/µL (difference + 14.7%, 95% CI 4.1-31.0). Logistic regression evinced that both DAA adherence and baseline CD4+ cell counts predicted the SVR (OR 3.9, 95% CI 1.8-8.8, and OR 5.2, 95% CI 1.9-13.9, respectively). Moreover, men who reported having sex with other men (MSM) were less likely to achieve SVR (OR 4.2, 95% CI 1.1-16.1). Among MSM, three of three patients without SVR were suspected to have experienced HCV reinfection. DAA for HCV in HIV-coinfected patients is highly effective. DAA adherence ≥ 95% and a baseline CD4+ count ≥ 200/µL predicted a higher probability of SVR. A lower rate of SVR was found in MSM, presumably due to a higher frequency of HCV reinfection.

RESUMEN

The role of viral load in the outcome of patients requiring hospital admission due to influenza is not well established. We aim to assess if there is an association between the viral load and the outcome in hospitalized patients with a confirmed influenza virus infection. A retrospective observational study including all adult patients who were hospitalized in our center with a confirmed influenza virus infection from January to May 2016. Viral load was measured by real-time reverse-transcriptase-polymerase chain reaction (rRT-PCR) cycle threshold (Ct) value on upper respiratory tract samples. Its value was categorized into three groups (low Ct, ≤ 20; intermediate Ct, > 20-30; and high Ct, > 30). Two hundred thirty-nine patients were included. Influenza A/H1N1pdm09 was isolated in 207 cases (86.6%). The mean Ct value was 26.69 ± 5.81. The viral load was higher in the unvaccinated group when compared with the vaccinated patients (Ct 25.17 ± 5.55 vs. 27.58 ± 4.97, p = 0.004). Only 27 patients (11.29%) presented a high viral load. Patients with a high viral load more often showed abnormal findings on chest X-ray (p = 0.015) and lymphopenia (p = 0.097). By contrast, there were no differences between the three groups (according to viral load), in associated pneumonia, respiratory failure, need for mechanical ventilation, sepsis, or in-hospital mortality. Our findings suggest that in patients admitted to the hospital with confirmed influenza virus infection (mostly A/H1N1pdm09), a high viral load is associated with a higher presence of abnormal findings on chest X-ray but not with a significant worse prognosis. In these cases, standardized quantitative PCR could be useful.

RESUMEN

INTRODUCTION: liver laboratory tests improve in hepatitis C virus (HCV)-monoinfected and cirrhotic patients who achieve HCV cure after interferon-free treatment. OBJECTIVE AND METHODS: this study evaluates the changes in those tests in human immunodeficiency virus (HIV)-positive subjects with an eradicated HCV-coinfection using direct-acting antivirals and with a pre-therapy liver stiffness ≥ 14.6 kPa or clinical data of cirrhosis. Serum albumin, bilirubin, creatinine, platelet count and international normalized ratio (INR) values were collected at baseline, week 4, at the end of treatment and 24 weeks after the end-of-treatment. Fibrosis-4 score (FIB4) and Model for End-stage Liver Disease (MELD) score values were calculated and liver stiffness was estimated by transient elastography at baseline and 24 weeks after the end-of-treatment. The means were compared with the Student's t test or the repeated measures ANOVA test. RESULTS: direct-acting antivirals were prescribed to 131 HIV/HCV-coinfected cirrhotic patients. A sustained virological response was confirmed in 120 cases. Albumin, bilirubin and platelet count values improved in the entire population 24 weeks after the end-of-treatment. INR and MELD score values decreased when patients with atazanavir and/or acenocoumarol were excluded and liver fibrosis tests significantly diminished. Nine patients developed liver decompensation and there were three deaths. CONCLUSION: in conclusion, HCV eradication was associated with a short-term improvement in biochemical liver function and fibrosis tests in HIV-coinfected patients with cirrhosis, although clinical events still occur.

RESUMEN

Functional status linked to a poor outcome in a broad spectrum of medical disorders. Barthel Activities of Daily Life Index (BADLI) is one of the most extended tools to quantify functional dependence. Whether BADLI can help to predict outcomes in elderly patients with acute venous thromboembolism (VTE) is unknown. The current study aimed to ascertain the influence of BADLI on 6-month all-cause mortality in aged patients with VTE. This is a prospective observational study. We included consecutive patients older than 75-year-old with an acute VTE between April 2015 and April 2017. We analyzed several variables as mortality predictors, including BADLI-measured functional status. Afterward, we performed a multivariate analysis, using logistic regression, to identify all-cause mortality independent predictive factors. Two hundred and two subjects were included. Thirty-five (17%) patients died in the first 6 months. The leading cause of death was cancer (59%). After multivariable logistic regression, we identified BADLI and Charlson index as independent predictors for 6-months mortality [BADLI (every decrease of 10 points) OR 1.21 95% CI (1.03-1.42) and Charlson index OR 1.71 95% CI (1.21-2.43)]. Body mass index (BMI) values were inversely related to mortality [OR 0.85 95% CI (0.75-0.95)]. In conclusion, BADLI, BMI, and Charlson index scores are independent predictive factors for 6-month all-cause mortality in old patients with VTE.
