Sorafenib after RFA in HCC patients: a pilot study.

BACKGROUND/AIMS: To investigate the effectiveness and safety of sorafenib after radiofrequency ablation (RFA) in patients with hepatocellular carcinoma (HCC). METHODOLOGY: 44 intermediate or advanced HCC patients received sorafenib treatment after debulking with RFA therapy. Time to progression (TTP), response rate (RR), duration of sorafenib treatment and adverse effects were evaluated. An explorative comparison was performed with patients treated with sorafenib only. RESULTS: At 12 months, TTP was 10.3 months (range: 1-32). RR was 61% with 2 complete responses, and duration of sorafenib therapy was 10.9 months (1-32). No new safety concerns were report-ed. With sorafenib only, TTP was 7.2 months (range: 0-38) and RR was 40%, with one complete response; duration of therapy was 7.3 months (0-38). CONCLUSIONS: The sequence of RFA and sorafenib appears effective and safe in HCC patients. These findings could support the use of a sequential treatment with RFA and sorafenib in HCC patients.

Adherence to antiretroviral therapy thought package-refill among HIV+ persons at "D. Cotugno" hospital, Naples, Italy.

Background: A gold-standard for the measurement of adherence to antiretroviral therapy (ART) is lacking. Aim of this study is to verify the feasibility of a package-refill-based measurement of ART at "D. Cotugno" hospital, Naples, Italy, and the factors associated to adherence. Methods: In the period January 2018-August 2020, we calculated the package-refill as the ratio between ART-packages actually withdrawn, and the ART packages needed to regularly take ART. Adherence was associated, trough a univariate e multivariate logistic regression, to demographical, behavioural and clinical factors. Results: 1140 HIV+ subjects were included. At univariate logistic regression inadequate package-refill-based adherence is associated with HIV-RNA higher than 50 copies/mmL (OR 3.77-IC95% 2.76-5.13) and with HIVRNA higher than 200 copies/mmL (OR 3.98-IC95% 2.69-5.90). Being not-Italian and Injective-drug-user are associated with low adherence, having HIV/AIDS for more than 8 years is associated with better adherence. Conclusions: Package-refill is a suitable method for measuring adherence and is associated with the condition of viral failure.

Clinical Characterization of the Three Waves of COVID-19 Occurring in Southern Italy: Results of a Multicenter Cohort Study.

AIMS: To characterize patients hospitalized for COVID-19 in the three waves in Southern Italy. METHODS: We conducted a multicenter observational cohort study involving seventeen COVID-19 Units in Campania, southern Italy: All adult (≥18 years) patients, hospitalized with a diagnosis of SARS-CoV-2 infection from 28 February 2020 to 31 May 2021, were enrolled. RESULTS: Two thousand and fifteen COVID-19 hospitalized patients were enrolled; 392 (19%) in the first wave, 917 (45%) in the second and 706 (35%) in the third wave. Patients showed a less severe clinical outcome in the first wave than in the second and third waves (73%, 65% and 72%, respectively; p = 0.003), but hospitalization expressed in days was longer in the first wave [Median (Q1-Q3): 17 (13-25) v.s. 14 (9-21) and 14 (9-19), respectively, p = 0.001)] and also mortality during hospitalization was higher in the first wave than in the second and third waves: 16.6% v.s. 11.3% and 6.5%, respectively (p = 0.0001). Multivariate analysis showed that older age [OR: 1.069, CI (1046-1092); p = 0.001], a worse Charlson comorbidity index [OR: 1042, CI (1233-1594; p = 0.0001] and enrolment during the first-wave [OR: 1.917, CI (1.054-3.485; p = 0.033] were predictors of mortality in hospitalized patients. CONCLUSIONS: Improved organization of the healthcare facilities and the increase in knowledge of clinical and therapeutic management have contributed to a trend in the reduction in mortality during the three waves of COVID-19.

Evolving epidemiology of HIV/AIDS in Campania region, 2011-2018: Is HIV/AIDS population in Campania different?

Objectives: Data on HIV/AIDS cases in Italy are collected using a standardised form. Regional epidemiology may vary. We described the epidemiological and clinical characteristics of newly diagnosed persons with HIV in the 'Cotugno' hospital in Naples during 2011-2018 and compared them with national data to identify similarities and differences. Methods: Data source for the Campania region is the data collection forms sent to the national surveillance system. The data source for the national data is from the periodic annual bulletins on HIV/AIDS published by the National Institute of Health. Results: In all, 1149 persons with HIV were diagnosed in 'Cotugno' (69.7% of those diagnosed in Campania). Persons with HIV in Campania showed many similarities with the Italian population: men were in the majority in both groups (about 75%), foreign origin was about 30%, heterosexuals were the most represented risk group, followed by men who have sex with men and injecting drug use in both samples. Some notable differences are also present. Among the risk factors for HIV acquisition, injecting drug use is significantly more common in Campania. Among the reasons for testing, significant differences are evident for almost all reasons, with screening activities (testing for concurrent diseases, for diagnosis of sexually transmitted diseases, screening in hospital during maternity care and screening in drug-addition services or prisons) being more common at the national level. The Campania population has a more severe disease pattern, with a significantly higher proportion of patients diagnosed with less than 200 CD4 cells/µL and AIDS. For each variable, we compared trends in the Campania region and in Italy using Spearman's correlation coefficient. Almost all trends show a weak correlation. Conclusion: In conclusion, the prevalence of injecting drug use is still consistent, and requires specific campaigns. The reasons for testing are different: screening activities work less in Campania than in Italy. This untimely approach contributes to a more severe clinical picture in Campania.

Pre-existing chronic kidney disease (CDK) was not associated with a severe clinical outcome of hospitalized COVID-19: results of a case-control study in Southern Italy.

The presence of co-morbidities is associated with a poor outcome in patients with COVID-19. The aim of the present study was to investigate the outcomes of patients with SARS-CoV-2 infection and chronic kidney disease (CKD) in order to assess its impact on mortality and severity of disease. We performed a multicenter, observational, 1:2 matched case-control study involving seventeen COVID-19 Units in southern Italy. All the adults hospitalized for SARS-CoV-2 infection and with pre-existing CKD were included (Cases). For each Case, two patients without CKD pair matched for gender, age (+5 years), and number of co-morbidities (excluding CKD) were enrolled (Controls). Of the 2,005 patients with SARS-CoV-2 infection followed during the study period, 146 patients with CKD and 292 patients without were enrolled in the case and control groups, respectively. Between the Case and Control groups, there were no statistically significant differences in the prevalence of moderate (17.1% vs 17.8%, p=0.27) or severe (18.8% and 13.7%, p=0.27) clinical presentation of COVID-19 or deaths (20.9% vs 28.1%, p=0.27). In the Case group, the patients dead during hospitalization were statistically higher in the 89 patients with CKD stage 4-5 compared to 45 patients with stages 1-3 CKD (30.3% vs 13.3%, p=0.03). Our data suggests that only CKD stage 4-5 on admission was associated with an increased risk of in-hospital death.

Reactivation of overt and occult hepatitis B infection in various immunosuppressive settings.

The aim of the study was to evaluate clinical and virological differences in HBV reactivation between patients with overt and occult HBV infection. Twenty-three consecutive patients with symptomatic HBV reactivation occurring during or after immunosuppressive therapy were enrolled in a retrospective study: 10 with reactivation of overt HBV infection (overt group) and 13 of occult HBV infection (occult group). Twenty-one patients were treated with nucleot(s)ide analogues after HBV reactivation. Regimens including rituximab or fludarabine were administered more frequently in the occult group (61% vs. 31%, respectively). HBV reactivation was severe frequently in the overt (40%) and occult groups (38.4%). Patients in the overt group showed higher HBV-DNA titers (1.1 × 10(8) ± 1.4 × 10(8) vs. 5.1 × 10(5) ± 6.8 × 10(5) IU; P < 0.005). Seven patients died during HBV reactivation, two in the overt and five in the occult group. Of these seven patients, two remained untreated and five had been treated with Lamivudine; of the 16 patients showing remission of HBV reactivation, four had been treated with Lamivudine, four with Entecavir, two with Telbivudine, and six with Lamivudine plus Adefovir. It is concluded that HBV reactivation is life-threatening in patients with diseases inhibiting the immune response and/or receiving immunosuppressive drugs. Supportive therapy without antiviral drugs or Lamivudine monotherapy may not be effective for treating patients with HBV reactivation.

Genetic Variability in Patients with HCV-Related Hepatocellular Carcinoma.

BACKGROUND: The present paper evaluates the genetic variability of HCV in patients with hepatocellular carcinoma (HCC). METHODS: Amino acid substitutions (aas) in NS3, NS5A and core regions were analyzed in 17 patients with HCC (Cases) and 13 without HCC (Controls), all naïve to DAAs. For the Cases, a sample of neoplastic liver tissue, non-neoplastic liver tissue and a serum sample were collected; for the Controls, a sample of liver tissue was collected. Sanger sequencing of three regions was performed using homemade protocols. RESULTS: Phylogenetic trees showed that there was no difference in the virus populations in the three compartments analyzed for the three HCV regions in patients with HCC. Low variability and no difference between the Cases and Controls were observed in the core and NS5A regions; however, in the NS3 region, a higher variability was observed in the Cases. No difference was observed in the core region between Cases and Controls. In NS3, aa substitutions at positions 103 and 122 were more frequently found in Cases than Controls (in both cases 50% vs 9.1%, p<0.05); moreover, aas in positions 32, 44 (p=0.035 for both), 79 (p=0.008) and 121 (p=0.018) were observed in the Cases and absent in the Controls. Finally, considering the NS5A region, aa substitutions at positions 37 and 54 were more frequently identified in the Cases than the Controls, but without statistical significance. CONCLUSION: These data may suggest a higher aa variability in patients with HCC than in those without, especially in the NS3 region.

Use of lung ultrasound in COVID-19: comparison with ultra-high-resolution computed tomography among 29 patients at "D. Cotugno" hospital, Naples, Italy.

Ultra-High-Resolution Computed Tomography (U-HR-CT) is the reference imaging technique for pneumonia in the new coronavirus disease (COVID-19). Pulmonary Ultrasound (LUS) could be a valid diagnostic alternative for the imaging of COVID-19. Our study aimed to investigate the clinical performance of LUS in the initial evaluation of pneumonia in COVID-19 patients, compared to standard U-HR-CT. Among 29 patients with confirmed COVID-19, all U-HR-CT hallmarks showed an excellent concordance with LUS findings according to Cohen coefficient. In our experience, LUS is a viable alternative to U-HR-CT, with the advantages of being radiation-free, flexible, cost-effective, and reasonably reducing nosocomial transmission risks because performed at bed-side.

Differences among confirmed and not-confirmed COVID-19 patients at "D.Cotugno" hospital, Naples (Italy): what we learned from first suspected cases?

Clinical presentation of COVID-19 is common to other respiratory infections. We compared the characteristics at hospital admission of confirmed and not-confirmed COVID-19 patients, in the early phase of the epidemic. Thirty-seven suspected patients were enrolled, and COVID-19 was confirmed in 17. Confirmed patients are older, have more frequently contact with confirmed cases. Distinctive clinical characteristics among COVID-19 were the grand-glass opacities at CT scan, and a pO2/FiO2 ratio less than 250. In not-confirmed group, Influenza represented the most frequent alternative diagnosis. This study contributes to highlight the characteristics to consider at hospital admission in order to promptly suspect COVID-19.

[Spontaneous and treatment-induced virological dynamic in the plasma, PBMC and liver tissue in a patient with chronic HBV and HCV coinfection]. / Dinamica virologica di HBV e HCV spontanea e correlata alla terapia nel plasma, nei PBMC e nel tessuto epatico in un paziente con coinfezione cronica da HBV e HCV.

Here it is reported the virological dynamic of HBV and HCV, identified in the plasma, peripheral blood mononuclear cells and tissue liver, in a patient with chronic HBV-HCV coinfection. A treatment with pegylated Interferon plus Ribavirin determined a sustained virological response for HCV in all the three studied compartments, but a reactivation of chronic HBV infection was observed. In fact, while at the first observation HBV-DNA was detectable only in the liver tissue, after antiviral therapy it was detectable in all the three compartments; moreover this HBV reactivation was associated with a hepatic flare. Then, the patient was treated with Entecavir, which has been determining the clearance of HBV from the peripheral compartments (plasma and PBMC) until today.

Association between Work Related Stress and Health Related Quality of Life: The Impact of Socio-Demographic Variables. A Cross Sectional Study in a Region of Central Italy.

The aim of this work is investigate relationship between health-related quality of life and work-related stress and the impact of gender, education level, and age on this relationship. A cross-sectional study was conducted among workers of various setting in Rome and Frosinone. Work-related stress was measured with a demand-control questionnaire and health-related functioning by SF (short form)-12 health survey. There were 611 participants. Men reported high mental composite summary (MCS) and physical composite summary (PCS). In multivariate analysis age, gender (p < 0.001) and job demand (0.045) predicted low PCS. Low MCS predicted poor PCS. Job demand and educational level resulted negatively associated with MCS. In an analysis stratified for age, gender, and educational level, gender and age resulted effect modifier for MCS, gender and education level for PCS. In women increase of decision latitude predict (p = 0.001) an increase in MCS; a low job demand predict high MCS in male (p ≤ 0.001). In younger workers, a lower level of job demand predicted high MCS (<0.001). For PCS, gender and education level resulted effect modifier. In women, high decision latitude predicted higher PCS (p = 0.001) and lower level of job demand results in higher PCS (p ≤ 0.001). Higher educational level resulted predictor of low PCS. Management of risk about work-related stress should consider socio-demographic factors.

Lowered expression of microRNA-125a-5p in human hepatocellular carcinoma and up-regulation of its oncogenic targets sirtuin-7, matrix metalloproteinase-11, and c-Raf.

Human microRNA-125a-5p (miR-125a) is expressed in most tissues where it downregulates the expression of membrane receptors or intracellular transductors of mitogenic signals, thus limiting cell proliferation. Expression of this miRNA generally increases with cell differentiation whereas it is downregulated in several types of tumors, such as breast, lung, ovarian, gastric, colon, and cervical cancers, neuroblastoma, medulloblastoma, glioblastoma, and retinoblastoma. In this study, we focused on hepatocellular carcinoma and used real-time quantitative PCR to measure miR-125a expression in 55 tumor biopsies and in matched adjacent non-tumor liver tissues. This analysis showed a downregulation of miR-125a in 80 % of patients, with a mean decrease of 4.7-fold. Comparison of miRNA downregulation with clinicopathological parameters of patients didn't yield significant correlations except for serum bilirubin. We then evaluated the expression of known targets of miR-125a and found that sirtuin-7, matrix metalloproteinase-11, and c-Raf were up-regulated in tumor tissue by 2.2-, 3-, and 1.7-fold, respectively. Overall, these data support a tumor suppressor role for miR-125a and encourage further studies aimed at the comprehension of the molecular mechanisms governing its expression, eventually leading to treatments to restore its expression in tumor cells.

Occult HBV infection in HCC and cirrhotic tissue of HBsAg-negative patients: a virological and clinical study.

AIM: To evaluate the virological and clinical characteristics of occult HBV infection (OBI) in 68 consecutive HBsAg-negative patients with biopsy-proven cirrhosis and HCC. METHODS: HBV DNA was sought and sequenced in plasma, HCC tissue and non-HCC liver tissue by PCRs using primers for HBV core, surface and x regions. OBI was identified by the presence of HBV DNA in at least two different PCRs. RESULTS: OBI was detected in HCC tissue of 13 (20%) patients and in non-HCC liver tissue of 3 of these 13. OBI was detected in HCC tissue of 54.5% of 11 anti-HBs- negative/anti-HBc-positive patients, in 29.4% of 17 anti-HBs/anti-HBc-positive and in 5% of 40 anti-HBs/anti-HBc-negative (p < 0.0005). The 13 patients with OBI in HCC tissue more frequently than the 55 without showed Child-B or -C cirrhosis (53.9% vs. 5.5%, p < 0.0001) and BCLC-B or -C stages (46.1% vs. 1.8%, p < 0.0001). The pre-S1, pre-S2 and S region sequences in HCC tissue showed amino acid (AA) substitutions (F19L, P24L, S59F, T131I, Q129H) and deletions (in positions 4,8, 17 and 86) in the S region, AA substitutions (T40S, P124K, L54P, G76A, N222T and I273L) in pre-S1 region and AA substitutions in pre-S2 region (P41H and P66L). In the 3 patients showing OBI also in non-HCC liver tissue the S, pre-S1 and pre-S2 sequencing displayed patterns of mutations different. CONCLUSIONS: The study showed a significant correlation between OBI and the severity of liver damage, several patterns of mutations in the S, pre-S1 and pre-S2 regions in HCC tissue, some at their first description.

Increased hepatitis C viral load and reactivation of liver disease in HCV RNA-positive patients with onco-haematological disease undergoing chemotherapy.

AIMS: To evaluate changes in Hepatitis C Virus (HCV) RNA both in plasma and Peripheral Blood Mononuclear Cells (PBMC) in onco-haematological patients. PATIENTS AND METHODS: 8 consecutive anti-HCV/HCV RNA-positive patients with onco-haematological diseases (5 with B-cell Non-Hodgkin Lymphoma and 3 with chronic lymphocytic leukaemia) were observed during chemotherapy and after its discontinuation. All were naïve to chemotherapy. HCV RNA was sought by Real Time Polymerase Chain Reaction in Light Cycler 1.5 in plasma and PBMC samples collected before, during and after chemotherapy. RESULTS: An increase in HCV RNA of at least 1.5 log IU/mL in plasma and 1.1 log IU/ml in PBMC was observed in all 7 patients undergoing Rituximab-based chemotherapy; these patients showed a hepatic flare after discontinuation, life-threatening in one with cirrhosis. Also the 8th patient had cirrhosis, but was treated with Rituximab-sparing chemotherapy and did not show any increase in HCV RNA or a hepatic flare. CONCLUSION: Rituximab-based chemotherapy favours an increase in HCV RNA in onco-haematological patients; this is followed by a hepatic flare, possibly immune-mediated and life threatening in cirrhotic patients.

[Icteric hepatitis in a patient with non-Hodgkin's lymphoma treated by rituximab-based chemotherapy]. / Epatite itterica in paziente con Linfoma non-Hodgkin sottoposto a chemioterapia basata su rituximab.

We report the case of a patient with non-Hodgkin's lymphoma who, during chemotherapy according to the r-CHOP schedule (rituximab-cyclophosphamide-doxorubicin-vincristine and prednisone), showed a hepatic flare with jaundice. Given the patient's state of asymptomatic carrier of HBsAg, we began a treatment of telbivudine (600 mg/die), resulting in a regression of hepatitis flare and negativization of HBV viraemia.
