ABSTRACT
OBJECTIVE: Selected populations of patients with chronic hepatitis B (CHB) may benefit from a combined use of pegylated interferon-alpha (pegIFN-α) and nucleos(t)ides (NUCs). The aim of our study was to assess the immunomodulatory effect of pegIFN-α on T and natural killer (NK) cell responses in NUC-suppressed patients to identify cellular and/or serological parameters to predict better T cell-restoring effect and better control of infection in response to pegIFN-α for a tailored application of IFN-α add-on. DESIGN: 53 HBeAg-negative NUC-treated patients with CHB were randomised at a 1:1 ratio to receive pegIFN-α-2a for 48 weeks, or to continue NUC therapy and then followed up for at least 6 months maintaining NUCs. Serum hepatitis B surface antigen (HBsAg) and hepatitis B core-related antigen (HBcrAg) levels as well as peripheral blood NK cell phenotype and function and HBV-specific T cell responses upon in vitro stimulation with overlapping HBV peptides were measured longitudinally before, during and after pegIFN-α therapy. RESULTS: Two cohorts of pegIFN-α treated patients were identified according to HBsAg decline greater or less than 0.5 log at week 24 post-treatment. PegIFN-α add-on did not significantly improve HBV-specific T cell responses during therapy but elicited a significant multispecific and polyfunctional T cell improvement at week 24 post-pegIFN-α treatment compared with baseline. This improvement was maximal in patients who had a higher drop in serum HBsAg levels and a lower basal HBcrAg values. CONCLUSIONS: PegIFN-α treatment can induce greater functional T cell improvement and HBsAg decline in patients with lower baseline HBcrAg levels. Thus, HBcrAg may represent an easily and reliably applicable parameter to select patients who are more likely to achieve better response to pegIFN-α add-on to virally suppressed patients.
ABSTRACT
BACKGROUND: The safety and efficacy of sofosbuvir-velpatasvir in children aged 3-17 years with chronic hepatitis C virus (HCV) infection of any genotype were evaluated. METHODS: In this Phase 2, multicenter, open-label study, patients received once daily for 12 weeks either sofosbuvir-velpatasvir 400/100 mg tablet (12-17 years), 200/50 mg low dose tablet or oral granules (3-11 years and ≥17 kg), or 150/37.5 mg oral granules (3-5 years and <17 kg). The efficacy endpoint was sustained virologic response 12 weeks after therapy (SVR12). Dose appropriateness was confirmed by intensive pharmacokinetics in each age group. FINDINGS: Among 216 patients treated, 76% had HCV genotype 1% and 12% had genotype 3. Rates of SVR12 were 83% (34/41) among 3-5-year-olds, 93% (68/73) among 6-11-year-olds, and 95% (97/102) among 12-17-year-olds. Only two patients experienced virologic failure. The most common adverse events were headache, fatigue, and nausea in 12-17-year-olds; vomiting, cough, and headache in 6-11-year-olds; and vomiting in 3-5-year-olds. Three patients discontinued treatment because of adverse events. Four patients had serious adverse events; all except auditory hallucination (n = 1) were considered unrelated to study drug. Exposures of sofosbuvir, its metabolite GS-331007, and velpatasvir were comparable to those in adults in prior Phase 2/3 studies. Population pharmacokinetic simulations supported weight-based dosing for children in this age range. INTERPRETATION: The pangenotypic regimen of sofosbuvir-velpatasvir is highly effective and safe in treating children 3-17 years with chronic HCV infection.

BACKGROUND AND AIMS: Mixed cryoglobulinemia is the most common HCV extrahepatic manifestation. We aimed to prospectively evaluate the cryoglobulinemic vasculitis (CV) clinical profile after a sustained virologic response (SVR) over a medium-term to long-term period. APPROACH AND RESULTS: Direct-acting antiviral-treated cryoglobulinemic patients, consecutively enrolled in the multicentric Italian Platform for the Study of Viral Hepatitis Therapy cohort, were prospectively evaluated. Cumulative incidence Kaplan-Meier curves were reported for response, clinical deterioration, relapse and relapse-free survival rates. Cox regression analysis evaluated factors associated with different outcomes. A clinical response was reported in at least one follow-up point for 373 of 423 (88%) patients with CV who achieved SVR. Clinical response increased over time with a 76% improvement rate at month 12 after the end of treatment. A full complete response (FCR) was reached by 164 (38.8%) patients in at least one follow-up point. CV clinical response fluctuated, with some deterioration of the initial response in 49.6% of patients (median time of deterioration, 19 months). In patients who achieved FCR and had an available follow-up (137 patients) a relapse was observed in 13% and it was transient in 66.7% of patients. The rate of patients without any deterioration was 58% and 41% at 12 and 24 months, respectively. After achieving SVR, a clinical nonresponse was associated with older age and renal involvement; a clinical deterioration/relapse was associated with high pretreatment rheumatoid factor values, and FCR was inversely associated with age, neuropathy, and high cryocrit levels. CONCLUSION: In patients with CV, HCV eradication may not correspond to a persistent clinical improvement, and clinical response may fluctuate. This implies an attentive approach to post-SVR evaluation through prognostic factors and tailored treatment.

To date, few reports have evaluated the pneumococcal vaccination status in cirrhotic patients. No data are available for European countries. We have explored this topic and the potential independent predictors motivating lack of vaccination in Italy. Between January 1st and June 30th 2022, 1419 cirrhotic patients of any etiology were consecutively enrolled in an observational, prospective study at 8 referral centers in Italy. Adjusted odds ratios (ORs) for the association with lack of vaccination were evaluated by multiple logistic regression analysis. Overall vaccine coverage was 17.9% (8.9% in patients < 65 years of age and 27.1% in those aged ≥ 65 years; p < 0.001). Among the 1165 unvaccinated patients, 1068 (91.7%) reported lack of information regarding vaccination as the reason for not having undergone vaccination. Independent predictors associated with lack of vaccination were age < 65 years (OR 3.39, CI 95% 2.41-4.76) and a higher number of schooling years (OR 2.14, CI 95% 1.58-2.91); alcoholic etiology resulted only marginally associated (OR 1.91, CI 95% 1.03-3.52). These findings establish evidence on how pneumococcal vaccination status in Italy is largely suboptimal among cirrhotic patients. These results raise concern, considering the severe outcomes of pneumococcal infection in patients with chronic liver diseases.

BACKGROUND: Since the end of February 2020, the Coronavirus Disease 2019 (COVID-19) outbreak rapidly spread throughout Italy and other European countries, but limited information has been available about its characteristics in HIV-infected patients. METHODS: We have described a case series of patients with HIV infection and COVID-19 diagnosed at the S.Orsola Hospital (Bologna, Italy) during March and April, 2020. RESULTS: We reported a case series of 26 HIV-infected patients with COVID-19. Nineteen subjects were men, the median age was 54 years, 73% of patients had one or more comorbidities. Only 5 patients with interstitial pneumonia were hospitalized, but there were no admissions to intensive care unit and no deaths. CONCLUSIONS: In our experience, COVID-19 associated with HIV infection had a clinical presentation comparable to the general population and was frequently associated with chronic comorbidities.

We report the case of a man affected by cystic fibrosis who developed a severe SARS-CoV-2 related pneumonia in March 2020. In addition to lopinavir/ritonavir and hydroxychloroquine, he was treated with two doses of tocilizumab, displaying a significant clinical improvement. This is the first case described in the literature of an adult patient affected by cystic fibrosis who received tocilizumab for COVID-19, with documented total recovery, also assessed by a spirometry.

BACKGROUND: We analyzed the impact of continuous/extended infusion (C/EI) vs intermittent infusion of piperacillin-tazobactam (TZP) and carbapenems on 30-day mortality of patients with liver cirrhosis and bloodstream infection (BSI). METHODS: The BICRHOME study was a prospective, multicenter study that enrolled 312 cirrhotic patients with BSI. In this secondary analysis, we selected patients receiving TZP or carbapenems as adequate empirical treatment. The 30-day mortality of patients receiving C/EI or intermittent infusion of TZP or carbapenems was assessed with Kaplan-Meier curves, Cox-regression model, and estimation of the average treatment effect (ATE) using propensity score matching. RESULTS: Overall, 119 patients received TZP or carbapenems as empirical treatment. Patients who received C/EI had a significantly lower mortality rate (16% vs 36%, P = .047). In a Cox-regression model, the administration of C/EI was associated with a significantly lower mortality (hazard ratio [HR], 0.41; 95% confidence interval [CI], 0.11-0.936; P = .04) when adjusted for severity of illness and an ATE of 25.6% reduction in 30-day mortality risk (95% CI, 18.9-32.3; P < .0001) estimated with propensity score matching. A significant reduction in 30-day mortality was also observed in the subgroups of patients with sepsis (HR, 0.21; 95% CI, 0.06-0.74), acute-on-chronic liver failure (HR, 0.29; 95% CI, 0.03-0.99), and a model for end-stage liver disease score ≥25 (HR, 0.26; 95% CI, 0.08-0.92). At competing risk analysis, C/EI of beta-lactams was associated with significantly higher rates of hospital discharge (subdistribution hazard [95% CI], 1.62 [1.06-2.47]). CONCLUSIONS: C/EI of beta-lactams in cirrhotic patients with BSI may improve outcomes and facilitate earlier discharge.

We evaluated the cost-effectiveness of two alternative direct-acting antiviral (DAA) treatment policies in a real-life cohort of hepatitis C virus-infected patients: policy 1, "universal," treat all patients, regardless of fibrosis stage; policy 2, treat only "prioritized" patients, delay treatment of the remaining patients until reaching stage F3. A liver disease progression Markov model, which used a lifetime horizon and health care system perspective, was applied to the PITER cohort (representative of Italian hepatitis C virus-infected patients in care). Specifically, 8,125 patients naive to DAA treatment, without clinical, sociodemographic, or insurance restrictions, were used to evaluate the policies' cost-effectiveness. The patients' age and fibrosis stage, assumed DAA treatment cost of 15,000/patient, and the Italian liver disease costs were used to evaluate quality-adjusted life-years (QALY) and incremental cost-effectiveness ratios (ICER) of policy 1 versus policy 2. To generalize the results, a European scenario analysis was performed, resampling the study population, using the mean European country-specific health states costs and mean treatment cost of 30,000. For the Italian base-case analysis, the cost-effective ICER obtained using policy 1 was 8,775/QALY. ICERs remained cost-effective in 94%-97% of the 10,000 probabilistic simulations. For the European treatment scenario the ICER obtained using policy 1 was 19,541.75/QALY. ICER was sensitive to variations in DAA costs, in the utility value of patients in fibrosis stages F0-F3 post-sustained virological response, and in the transition probabilities from F0 to F3. The ICERs decrease with decreasing DAA prices, becoming cost-saving for the base price (15,000) discounts of at least 75% applied in patients with F0-F2 fibrosis. CONCLUSION: Extending hepatitis C virus treatment to patients in any fibrosis stage improves health outcomes and is cost-effective; cost-effectiveness significantly increases when lowering treatment prices in early fibrosis stages.

OBJECTIVES: To evaluate imaging features of microvascular invasion (MVI) in hepatocellular carcinoma (HCC) developed after direct-acting antiviral (DAA) therapy in HCV-related cirrhosis. METHODS: Retrospective cohort study on 344 consecutive patients with HCV-related cirrhosis treated with DAA and followed for 48-74 weeks. Using established imaging criteria for MVI, HCC features were analysed and compared with those in nodules not occurring after DAA. RESULTS: After DAA, HCC developed in 29 patients (single nodule, 18 and multinodular, 11). Median interval between therapy end and HCC diagnosis was 82 days (0-318). Forty-one HCC nodules were detected (14 de novo, 27 recurrent): maximum diameter was 10-20 mm in 27, 20-50 mm in 13, and > 50 mm in 1. Imaging features of MVI were present in 29/41 nodules (70.7%, CI: 54-84), even in 17/29 nodules with 10-20 mm diameter (58.6%, CI: 39-76). MVI was present in only 17/51 HCC nodules that occurred before DAA treatment (33.3%, CI: 22-47) (p= 0.0007). MVI did not correlate with history of previous HCC. CONCLUSIONS: HCC occurs rapidly after DAA therapy, and aggressive features of MVI characterise most neoplastic nodules. Close imaging evaluations are needed after DAA in cirrhotic patients. KEY POINTS: ⢠In HCV cirrhosis, hepatocellular carcinoma develops soon after direct-acting antiviral therapy. ⢠HCC presents imaging features of microvascular invasion, predictive of more aggressive progression. ⢠Cirrhotic patients need aggressive and close monitoring after direct-acting antiviral therapy.

Direct-acting antivirals (DAAs) for the treatment of HCV have dramatically increased the rate of sustained virological response: patients not achieving sustained virological response represent a challenge and rates of late recurrent viremia are very low. We describe here the first case of a very late HCV relapse, following an atypical kinetics (characterized by a spontaneous but transient HCV clearance after an early virological relapse), in a HIV co-infected patient treated with DAAs. Optimal adherence to the therapy was well documented and a phylogenetic analysis ruled out a possible reinfection from a different HCV strain. In conclusion, our case underlines the importance of a long follow-up (> 48 weeks) after DAAs therapies in HCV-HIV co-infected patients who might benefit the most from a very rigorous virological surveillance.

PURPOSE: To assess the performance of two-dimensional shear wave elastography (2D-SWE) on the GE LOGIQ E9 ultrasound system in a cohort of healthy subjects and to investigate its accuracy in the staging of liver fibrosis in patients with chronic liver disease (CLD) using liver biopsy as a reference standard. MATERIALS AND METHODS: From October 2014 to June 2016, 54 healthy subjects and 174 patients with CLD were consecutively enrolled. Liver fibrosis stage was assessed by the METAVIR scoring system. 18 (10.3â%) and 17 (9.8â%) patients had advanced fibrosis and cirrhosis, respectively. The correlation of liver stiffness measurement (LSM) and continuous variable was assessed using the Spearman rank correlation. The accuracy of 2D-SWE was evaluated with areas under the receiver operating characteristics curves (AUROC). RESULTS: Reliable LSMs were obtained in all subjects. The interobserver agreement ICC was excellent: 0.847. In healthy subjects, gender, but not anthropometric and biochemical data, were correlated with LSM. In patients with CLD, LSM had a strong positive correlation with fibrosis stage (rhoâ=â0.628; pâ>â0.001). The AUROC was 0.724 for mild fibrosis (F≥â1), 0.857 for moderate fibrosis (F≥â2), 0.946 for severe fibrosis (F≥â3), and 0.935 for cirrhosis (F4). Likewise, good accuracy was observed in the HCV subgroup.âThe optimal cut-off value in differentiating healthy subjects from CLD patients with any fibrosis was 5.47 kPa with an AUROC of 0.875. CONCLUSION: 2D-SWE is a reliable and reproducible method to assess LSM with good diagnostic accuracy to assess liver fibrosis in patients with CLD.

Background: The impact on patient survival of an infectious disease (ID) team dedicated to the early management of severe sepsis/septic shock (SS/SS) in Emergency Department (ED) has yet to be assessed. Methods: A quasiexperimental pre-post study was performed at the general ED of our hospital. During the pre phase (June 2013-July 2014), all consecutive adult patients with SS/SS were managed according to the standard of care, data were prospectively collected. During the post phase (August 2014-October 2015), patients were managed in collaboration with a dedicated ID team performing a bedside patient evaluation within 1 hour of ED arrival. Results: Overall, 382 patients were included, 195 in the pre phase and 187 in the post phase. Median age was 82 years (interquartile range, 70-88). The most common infection sources were lung (43%) and urinary tract (17%); in 22% of cases, infection source remained unknown. During the post phase, overall compliance with the Surviving Sepsis Campaign (SSC) bundle and appropriateness of initial antibiotic therapy improved from 4.6% to 32% (P < .001) and from 30% to 79% (P < .001), respectively. Multivariate analysis showed that predictors of all-cause 14-day mortality were quick sepsis-related organ failure assessment ≥2 (hazard ratio [HR], 1.68; 95% confidence interval [CI], 1.15-2.45; P = .007), serum lactate ≥2 mmol/L (HR, 2.13; 95% CI, 1.39-3.25; P < .001), and unknown infection source (HR, 2.07; 95% CI, 1.42-3.02; P < .001); being attended during the post phase was a protective factor (HR, 0.64; 95% CI, 0.43-0.94; P = .026). Conclusion: Implementation of an ID team for the early management of SS/SS in the ED improved the adherence to SSC recommendations and patient survival.

BACKGROUND & AIMS: Elastography point quantification is a novel non-invasive method for the assessment of liver fibrosis by measuring liver stiffness. The aim of this study was to evaluate the accuracy of elastography point quantification for the diagnosis of liver fibrosis and to assess impact of steatosis on liver stiffness measurement, in a cohort of patients with chronic hepatitis C. METHODS: In this single-centre cross-sectional study, 211 consecutive patients with chronic hepatitis C, scheduled for liver biopsy, were examined with the elastography point quantification technology. On the same day, all patients underwent clinical examination, laboratory tests and abdominal ultrasound. RESULTS: The best cut-offs of liver stiffness measurement were 6.16 kPa for the diagnosis of significant fibrosis (≥S3) and 6.79 kPa for advanced fibrosis (≥S4). Areas under the receiver operating characteristic curve were 0.831 (CI: 0.773-0.880) for significant fibrosis, and 0.954 (CI: 0.916-0.978) for advanced fibrosis. Among patients within the same fibrosis stages (S0-S2 and S3-S6; S0-S3 and S4-S6), mean liver stiffness measurement values were similar in patients with steatosis (≥10% at liver biopsy or detected by ultrasound) compared to those without. Discordance between elastography point quantification and histology were affected by the presence of BMI>30 kg/m2 (P=.047, CI: 0.136-0.988 and P=.020, CI: 0.083-0.812 respectively). CONCLUSIONS: In patients with chronic hepatitis C, elastography point quantification is an accurate non-invasive method for the diagnosis of significant and advanced fibrosis. The presence of obesity is a risk factor for misclassification of significant and advanced liver fibrosis.

BACKGROUND & AIMS: The treatment of chronic hepatitis B infection (CHB) in children is still an area of great uncertainty. Vitamin E is an immunostimulating/antioxidant compound proven to be safe and effective for the treatment of adult CHB. The aim of this phase 2 controlled study was to evaluate the safety and efficacy of vitamin E for the treatment of paediatric HBeAg-positive CHB. METHODS: Forty-six children were randomized in a 1:1 ratio to receive vitamin E at a dose of 15 mg/kg/day (in galenic preparation) or no treatment for 12 months and were monitored for the subsequent 12 months. Clinical, biochemical, haematological and serovirological evaluations were carried out every 3 months. RESULTS: No significant side effects were associated with the vitamin E treatment. At the end of the study, anti-HBe seroconversion was obtained in 7 of 23 (30.4%) of vitamin E-treated versus 1 of 23 (4.3%) of the control patients (P = 0.05), while a virological response (≥2 log decrease in HBV-DNA from baseline) was observed in 9 of 23 (39.1%) vs. 2 of 23 (8.7%) respectively (P = 0.035). CONCLUSIONS: Vitamin E administration for the treatment of paediatric CHB at the tested dosage has no significant side effects and may induce anti-HBe seroconversion. Vitamin E could represent a tool for the treatment of paediatric CHB.

BACKGROUND & AIMS: Despite the excellent efficacy of direct-acting antivirals (DAA) reported in clinical trials, virological failures can occur, often associated with the development of resistance-associated substitutions (RASs). This study aimed to characterize the presence of clinically relevant RASs to all classes in real-life DAA failures. METHODS: Of the 200 virological failures that were analyzed in 197 DAA-treated patients, 89 with pegylated-interferon+ribavirin (PegIFN+RBV) and 111 without (HCV-1a/1b/1g/2/3/4=58/83/1/6/24/25; 56.8% treatment experienced; 65.5% cirrhotic) were observed. Sanger sequencing of NS3/NS5A/NS5B was performed by home-made protocols, at failure (N=200) and whenever possible at baseline (N=70). RESULTS: The majority of the virological failures were relapsers (57.0%), 22.5% breakthroughs, 20.5% non-responders. RAS prevalence varied according to IFN/RBV use, DAA class, failure type and HCV genotype/subtype. It was 73.0% in IFN group vs 49.5% in IFN free, with the highest prevalence of NS5A-RASs (96.1%), compared to NS3-RASs (75.9% with IFN, 70.5% without) and NS5B-RASs (66.6% with IFN, 20.4% without, in sofosbuvir failures). In the IFN-free group, RASs were higher in breakthrough/non-responders than in relapsers (90.5% vs 40.0%, P<.001). Interestingly, 57.1% of DAA IFN-free non-responders had a misclassified genotype, and 3/4 sofosbuvir breakthroughs showed the major-RAS-S282T, while RAS-L159F was frequently found in sofosbuvir relapsers (18.2%). Notably, 9.0% of patients showed also extra target RASs, and 47.4% of patients treated with ≥2 DAA classes showed multiclass resistance, including 11/11 NS3+NS5A failures. Furthermore, 20.0% of patients had baseline-RASs, which were always confirmed at failure. CONCLUSIONS: In our failure setting, RAS prevalence was remarkably high in all genes, with a partial exception for NS5B, whose limited resistance is still higher than previously reported. This multiclass resistance advocates for HCV resistance testing at failure, in all three genes for the best second-line therapeutic tailoring.

BACKGROUND & AIMS: Hepatocellular carcinoma (HCC) represents a serious complication of HCV-related cirrhosis. New direct-acting antivirals (DAA) cure HCV infection in over 90% of patients. The aim of this study was to evaluate the early occurrence and recurrence of HCC in cirrhotic patients treated with DAA. METHODS: We analysed 344 consecutive cirrhotic patients, without HCC, who were treated with DAA, and followed for 24weeks. Fifty-nine patients had previous HCC. RESULTS: DAA therapy induced sustained virological response in 91% of patients. During 24-week follow-up, HCC was detected in 26 patients (7.6%, 95% CI: 4.99-10.84): 17 of 59 patients (28.81%, 95% CI: 17.76-42.07) with previous HCC and 9 of 285 patients (3.16%, 95% CI: 1.45-5.90) without previous HCC. Child-Pugh Class B, more severe liver fibrosis, lower platelet count, and previous HCC were significantly associated with HCC development, at univariate analysis. At multivariate analysis, Child-Pugh class (p=0.03, OR: 4.18, 95% CI: 1.17-14.8) and history of HCC (p<0.0001, OR: 12.0, 95% CI: 4.02-35.74) resulted independently associated with HCC development. Among the 59 patients with previous HCC, younger age and more severe liver fibrosis were significantly associated with HCC recurrence, both at univariate and at multivariate analysis. CONCLUSIONS: In patients with HCV-related cirrhosis, DAA-induced resolution of HCV infection does not seem to reduce occurrence of HCC, and patients previously treated for HCC have still a high risk of tumour recurrence, in the short term. For these reasons, all cirrhotic patients should be closely monitored and followed during and after antiviral therapy. LAY SUMMARY: New direct-acting antivirals are able to eradicate HCV infection in over 90% of patients with advanced liver disease. Unfortunately, the occurrence of liver cancer is not reduced in effectively treated cirrhotic patients. In addition, patients previously treated for HCC have still a high risk of tumour recurrence in the short term, despite DAA treatment.

BACKGROUND & AIMS: Bloodstream infections (BSIs) in cirrhotic patients are 10-fold more common than in non-cirrhotic patients and increasingly caused by resistant pathogens. We examined 162 BSI episodes in cirrhotic patients to describe the etiology and risk factors for 30-day mortality. METHODS: We retrospectively analyzed all consecutive BSIs in patients with liver cirrhosis at our 1350-bed teaching hospital (January 2008 to June 2012). Cox-proportional hazard regression was used to analyze the impact of disease and treatment-related variables on the crude 30-day mortality. RESULTS: BSI episodes were identified in 162 patients, including 29 mixed infections. Most of episodes were classified as hospital acquired or healthcare associated (93%). Gram-negative bacteria (GNB), Gram-positive bacteria and Candida spp. caused 64%, 38%, and 10% of episodes, respectively. GNB were classified as multi-drug resistant (MDR) and extensively drug resistant (XDR) in 25% and 21% of cases, respectively. The overall crude 30-day mortality rate was 29%. Four risk factors were independently associated with 30-day crude mortality: worsening of MELD score from baseline (the last MELD score available in the 2 weeks prior BSI) to that at BSI onset (HR 1.11 per point increase, 95% CI 1.07-1.15, p<0.0001), spontaneous bacterial peritonitis as BSI source (HR 4.42, 2.04-9.54, p=0.002), sepsis grading (HR 2.18, 1.39-3.43, p=0.0007), and inappropriate antibiotic therapy within 24h from blood cultures (HR 2.82, 1.50-5.41, p=0.002). CONCLUSION: An increasing proportion of BSIs in cirrhotic patients are caused by resistant GNB and Candida spp. Accurate evaluation of risk factors for mortality may improve early appropriate therapeutic management.

OBJECTIVES: To define the impact of coinfection with hepatitis B virus (HBV) or hepatitis C virus (HCV) on viroimmunological response to raltegravir-based salvage regimens that also include new HIV inhibitors such as maraviroc, darunavir and etravirine. METHODS: We used data from a national observational study of patients starting raltegravir-based regimens to compare virological suppression and CD4 cell change from baseline in patients with and without concomitant HBV or HCV infection. RESULTS: Overall, 275 patients (107 coinfected and 168 non-coinfected) were evaluated. Coinfected patients were more commonly former intravenous drug users and had a longer history of HIV infection and higher baseline aminotransferase levels. Both HIV-RNA and CD4 response were similar in the two groups. Mean time to first HIV-RNA copy number <50 copies/mL was 4.1 months (95% CI 3.5-4.6) in non-coinfected patients and 3.9 months (95% CI 3.3-4.5) in coinfected patients (hazard ratio 1.039, 95% CI 0.761-1.418, P = 0.766, log-rank test). The risk of developing new grade 3-4 hepatic adverse events was significantly higher in coinfected patients (hazard ratio 1.779, 95% CI 1.123-2.817, P = 0.009). The two groups of coinfected and non-coinfected patients had similar rates of interruption of any baseline drug (hazard ratio 1.075, 95% CI 0.649-1.781, P = 0.776) and of raltegravir (hazard ratio 1.520, 95% CI 0.671-3.447, P = 0.311). Few AIDS-defining events and deaths occurred. CONCLUSIONS: Viroimmunological response to regimens based on raltegravir and other recent anti-HIV inhibitors is not negatively affected by coinfection with HBV or HCV. Liver toxicity, either pre-existing or new, is more common in coinfected patients, but with no increased risk of treatment interruption.

BACKGROUND AND AIMS: Few reports, all retrospective, have evaluated vaccine coverage against COVID-19 infection in cirrhotic subjects. No data are available for European Countries. We aimed to explore this topic and potential independent predictors of lack of vaccination. METHODS: Between January 1st and June 30th 2022, 1512 cirrhotic subjects of any etiology were consecutively enrolled in an observational - prospective study in 8 referral centers in Italy. Adjusted Odds Ratios (O.R.) for the association with lack of vaccination and with occurrence of breakthrough infection were evaluated by multiple logistic regression analysis. RESULTS: Overall vaccine coverage was 89.7% (80% among people born abroad). Among the 1358 vaccinated people, 178 (13.1%) had a breakthrough infection; of them 12 (6.7%) were hospitalized, but none died. Independent predictors associated with lack of vaccination were birth abroad, age <65 years and lower years of schooling. Child stage B/C was the only independent predictor of breakthrough infection. Occurrence of breakthrough infection was more likely reported in subjects who received 2 doses of vaccine than in those who received 3 doses (33.9% versus 9.0%; P<0.001). CONCLUSION: High vaccine coverage against COVID-19 infection is observed among cirrhotic subjects in Italy. Vaccine is effective in preventing severe outcomes. Three doses are more effective than two, even in cirrhotic subjects. LAY SUMMARY: This large cohort study evidenced high vaccine coverage against COVID-19 infection among cirrhotic subjects in a European country and the effectiveness of vaccine in preventing severe outcomes. Three doses of vaccine are more effective than two in preventing breakthrough infection and hospitalization. Informative campaigns targeting people younger than 65 years of age and those with lower years of schooling may increase these excellent results.

BACKGROUND AND AIMS: Severe liver disease markers assessed before HCV eradication are acknowledged to usually improve after the SVR. We prospectively evaluated, in the PITER cohort, the long-term HCC risk profile based on predictors monitored after HCV eradication by direct-acting antivirals in patients with cirrhosis. METHODS: HCC occurrence was evaluated by Kaplan-Meier analysis. Cox regression analysis identified the post-treatment variables associated with de-novo HCC; their predictive power was presented in a nomogram. RESULTS: After the end of therapy (median follow-up:28.47 months), among 2064 SVR patients, 119 (5.8%) developed de-novo HCC. The HCC incidence was 1.90%, 4.21%, 6.47% at 12-, 24- and 36-months from end-of-therapy, respectively (incidence rate 2.45/100 person-years). Age, genotype 3, diabetes, platelets (PLT)≤120,000/µl and albumin ≤3.5g/dl levels were identified as pre-treatment HCC independent predictors. Adjusting for age, the post-treatment PLT≤120,000/µl (AdjHR 1.92; 95%CI:1.06-3.45) and albumin≤3.5g/dl (AdjHR 4.38; 95%CI 2.48-7.75) values were independently associated with HCC occurrence. Two different risk profiles were identified by combining long-term post-therapy evaluation of PLT ≤ vs. >120,000/µl and albumin ≤ vs. >3.5g/dl showing a significant different HCC incidence rate of 1.35 vs. 3.77/100 p-y, respectively. CONCLUSIONS: The nomogram score based on age, PLT and albumin levels after SVR showed an accurate prediction capability and may support the customizing management for early HCC detection.
