RESUMO

BACKGROUND & AIMS: The safety and efficacy of hepatitis C (HCV) direct-acting antivirals (DAAs) have been established in several real-world trials; however, some reports have claimed an association between DAAs and hepatocellular carcinoma (HCC) occurrence or aggressive behavior. We aimed to prospectively examine differences in de-novo HCC tumor behavior and overall survival (OS) in DAAs-treated versus HCV-untreated patients as measured by BCLC progression during a two-year follow-up period. METHODS: This multicenter cohort study recruited 523 patients with de-novo HCV-related HCC. After exclusion criteria were applied, 353 patients were placed into; Group 1, including 236 patients without a history of DAAs therapy, and Group 2 including 117 patients with de-novo HCC developed after receiving DAAs. Patients were then stratified in each group according to BCLC staging (Liver, 2018). All patients received standard of care management and were followed until death or a maximum of 2 years. RESULTS: No statistically significant differences were observed between the two groups regarding tumor characteristics (number and size of lesions) and criteria for aggressiveness upon presentation. Among all BCLC stages, DAAs treated patients showed significantly lower baseline Fib4 values than DAA untreated patients in BCLC-0 stage (4.1 vs 7.7, p 0.019). No statistically significant differences were evident in HCC progression in the different BCLC stages at 12 and 24 months follow up periods (p 0.0718 and 0.279 respectively). Significantly better survival was recorded in Group 1 compared to Group 2 patients for BCLC stages C and D (p = 0.003 and 0.01, respectively). CONCLUSION: HCC may develop at an earlier stage of liver disease after DAAs therapy. No defensive role was found for DAAs treatment in delaying HCC progression that occurs after viral eradication.

RESUMO

The landscape of chronic liver disease in Egypt has drastically changed over the past few decades. The prevalence of metabolic-associated fatty liver disease (MAFLD) has risen to alarming levels. Despite the magnitude of the problem, no regional guidelines have been developed to tackle this disease. This document provides the clinical practice guidelines of the key Egyptian opinion leaders on MAFLD screening, diagnosis, and management, and covers various aspects in the management of MAFLD. The document considers our local situations and the burden of clinical management for the healthcare sector and is proposed for daily clinical practical use. Particular reference to special groups was done whenever necessary.

RESUMO

BACKGROUND: Reactivation of hepatitis B virus (HBV) infection in patients treated for chronic hepatitis C (HCV) with direct-acting antiviral agents has emerged recently as an important safety issue; however, it has not been adequately studied in pediatric age groups. We aimed to evaluate this risk in adolescent patients infected with chronic HCV and positive for HBsAg and HBcAbs. PATIENTS AND METHODS: One hundred and fifteen adolescent patients from 12 to 17 years of age, infected with chronic HCV and positive for HBcAbs with or without HBsAg were included in this study. All patients were treated with 1 tablet daily of the fixed-dose combination sofosbuvir/ledipasvir for 12 weeks. Patients were closely monitored throughout the study for virus load, liver functions, and other safety and efficacy outcome measures. RESULTS: The sustained virologic response 12 (SVR12) rates were 96.7% (95% confidence interval: 88.6-99.1%) in HBsAg positive group and 98.2% (95% confidence interval: 90.4-99.7%) in HBsAg negative with HBcAbs positive group. Throughout the treatment period and the 12 weeks follow-up after treatment, there has been no single case in both HBsAg negative or positive that showed any manifestation of reactivation of hepatitis B, detected levels of HBV-DNA, or deterioration of liver functions. CONCLUSION: No HBV reactivation was observed in adolescents treated for chronic HCV with direct-acting antiviral agents in our study, in both HBsAg positive or occult hepatitis B. Although results are reassuring, we still recommend close monitoring of liver functions to not miss even rare cases of such a potentially serious condition.

RESUMO

Debates are inevitable in science and could be a powerful tool for addressing controversial topics as it promotes critical thinking and inspires individuals to consider alternate viewpoints. However, debates can help only to identify the issues that need to be clarified to address this question, but it can never help resolve the controversy itself. In the era of evidence-based medicine, the need for an evidence-based debate is mandatory. Polarising opinions and major debate have recently arisen in hepatology on the nomenclature and diagnostic criteria for fatty liver disease associated with metabolic dysfunction (non alcoholic fatty liver disease [NAFLD]-metabolic (dysfunction) associated fatty liver disease [MAFLD] debate). The aim of this viewpoint is to suggest a way to settle the debate through evidence. Descriptive review using PubMed to identify literature on the evidence and eminence-based medicine and studies comparing MAFLD and NAFLD criteria. The emerging studies comparing the performance of diagnostic criteria of NAFLD and MAFLD represent the dawn of a new era for reframing the ongoing debate by acquisition of the mandatory evidence that will both resolve the debate and lead to novel avenues of research. In conclusion, the time has come to hold debate and focus on gathering and building the evidence to settle it. It does not matter who wins the debate and once there is robust evidence, we should all follow it wherever it leads.

RESUMO

BACKGROUND: Nonstructural protein 5A (NS5A) is an important regimen for the treatment of chronic hepatitis C virus (HCV) genotype-4 infected patients. Retreatments for NS5A virologic failure are limited. The aim of this study is to provide real-life data regarding the effectiveness and safety of retreatment with different regimens after NS5A regimen virologic failure in GT4 patients. PATIENTS AND METHODS: A total of 524 HCV patients (mean age 48 ± 11 years, 71% males), with virologic failure to sofosbuvir+daclatasvir, n = 450 and sofosbuvir/ledipasvir, n = 74 were included in this study. Patients were retreated with sofosbuvir + ombitasvir/paritaprevir/ritonavir + ribavirin, n = 278 and sofosbuvir + simeprevir + daclatasvir + ribavirin, n = 246. Response was evaluated 12 weeks after the end of treatment (SVR12). RESULTS: Overall, SVR12 was 95.2% [95% confidence interval (CI) 93.3%-97.1%]. In sofosbuvir + ombitasvir/paritaprevir/ritonavir + ribavirin and sofosbuvir + simeprevir + daclatasvir + ribavirin, SVR12s were 94.9% (95% CI 92.5%-97.4%) and 95.5% (95% CI 92.8%-98%), respectively. In liver cirrhosis patients, SVR12s were 96.4% (95% CI 90.7%-100%) and 98% (95% CI 94.9%-100%), respectively. Relapse in the sofosbuvir + ombitasvir/paritaprevir/ritonavir + ribavirin was n = 14 patients, and n = 11 patients in sofosbuvir + simeprevir + daclatasvir + ribavirin. Three patients developed hepatic encephalopathy, haematemesis, lower limb oedema, and one patient died in the SOF + OBV/PTV/RTV + RIB. In the sofosbuvir + simeprevir + daclatasvir + ribavirin, three patients developed hepatocellular carcinoma and one patient died. No treatment discontinuation due to anaemia. CONCLUSION: Salvage treatment for NS5A-treatment failure is effective and well tolerated in genotype-4 patients, in both noncirrhotic and compensated cirrhotic groups.

RESUMO

BACKGROUND & AIMS: Treatment of children aged 3-6 genotype 4 is still limited by the interferon side effects. We aimed in this study to evaluate the effectiveness and safety of sofosbuvir/ledipasvir in children (3-6 years) genotype 4 chronic HCV-infected patients. METHODS: In total, 22 consecutive chronic HCV-infected patients (mean age 4.8 ± 0.9years, 19 males) were included in this prospective study. All patients received sofosbuvir 200 mg/ledipasvir 45 mg in a single oral daily dose. Patients were randomly subdivided into two groups according the duration of treatment into 8 and 12 weeks. All the clinical and laboratory data were collected. All the side effects were recorded from the patients or their parents. Follow-up were made at Week 4, 8 and 12 and 12 weeks after the end of treatment (SVR12). RESULTS: The overall SVR12 rate was 100%. At Week 4, 9/11 patients in the 12-week group (81.8%; 95% CI: 52.3%-94.7%) achieved virologic negativity, vs 10/11 (90.9%; 95% CI: 62.3%-98.4%) in the 8-week group. At Week 8, 10/11 (90.8%; 95% CI: 62.3%-98.4%) in the 12-week group vs 11/11 (100%; 95% CI: 74.1%-100%) in the 8-week group were virologically negative. The reported side effects were cough, abdominal pain, nausea, vomiting and diarrhoea especially early in the treatment. The main complaint was difficulty in swallowing the tablets in the youngest patient at the beginning of the course of treatment. All patients were compliant to treatment. CONCLUSION: Sofosbuvir/ledipasvir combination is safe and tolerable in the chronic infected HCV genotype 4 infected children (3-6 years). The 8-week treatment duration is similarly effective as the 12-week duration.

RESUMO

BACKGROUND: Childhood cancer survivors are potentially at a higher risk of infection with hepatitis C virus (HCV). The effects of all-oral direct-acting antiviral therapy (DAA) on both the HCV infection as well as the state of cancer remission have not been well investigated in this population. AIM: To test the effects of dual sofosbuvir/daclatasvir (SOF/DCV) therapy in the treatment of chronic HCV in survivors of hematologic malignancy in pediatric age group. METHODS: We conducted a prospective, uncontrolled, open-label multicenter study. A total of 20 eligible, chronic HCV, genotype-4, infected children who had been in continuous complete remission from hematologic cancer (leukemia/lymphoma) for at least one year were included in the study. All patients were treated with combined SOF/DCV for 12 wk. Patients were monitored throughout the study till 12 wk after end of treatment for safety and efficacy outcomes including the sustained virologic response 12 (SVR12) rate, hematological indices, liver and kidney functions. RESULTS: The intent-to-treat SVR12 rate was 20 of 20 (100%; 95%CI: 84%-100%). All patients showed normalized liver enzymes from week-4. All hematological indices, liver and kidney functions were kept normal throughout the study. No fatalities or treatment-emergent serious or severe adverse events were reported throughout the study. CONCLUSION: SOF/DCV combined therapy could be used safely and effectively in the treatment of chronic HCV genotype-4 infection in leukemia/lymphoma treated children. No relapses were detected during treatment and throughout the follow up period for either the original malignant disease or the HCV infection.

RESUMO

Negative effects on growth indices had been reported in children treated with interferon for chronic viral hepatitis. Forty chronic hepatitis C virus-infected adolescents, 12-17 years of age, were treated with sofosbuvir/daclatasvir therapy for 12 weeks. The intent-to-treat sustained virologic response rate at 12 weeks after end of treatment was 39/40 (97.5%). Unlike interferon-based therapy, we did not detect significant negative effects on linear growth or weight. Contrarily, a trend to increased appetite and insignificant weight gain was observed, but further larger studies are needed to confirm. See Video-Abstract, http://links.lww.com/ASAIO/A381.

RESUMO

BACKGROUND: The sustained virological response (SVR) rate for the 12-week sofosbuvir (SOF)/ledipasvir (LVD) treatment of adolescent genotype-4 patients is high. The aim of this study is to evaluate 8 versus 12-week treatment efficacy and safety in adolescent genotype-4 patients. PATIENTS AND METHODS: In total, 157 chronic hepatitis C-infected adolescent patients (mean age 14±2 years, 62% males) were included in this study. All patients received a morning dose of SOF (400 mg)/LVD (90 mg) as a single tablet for 8 and 12 weeks. Laboratory and biochemical monitoring were performed at weeks 4 and 8, end of treatment (8/12) and 12 weeks after the end of treatment (SVR12). RESULTS: In total, SVR12 was 98% [95% confidence interval (CI): 96-100] for all treated patients. For patients treated for 12 weeks, SVR12 was 97.6% (95% CI: 96-101) (82/84 patients), and 98.6% (95% CI: 93-101) (72/73) patients for those treated for 8 weeks. For both regimens, no serious adverse effects, treatment discontinuation or cases of death were detected. The main adverse effects for the 8-week patient group were fatigue (2.8%), headache (1.4%), nausea (1.4%) and epigastric tenderness (1.4%). For the 12-week-treated group, adverse events were epigastric tenderness (1.2%), nausea (1.2%), diarrhoea (2.4%) and rash (2.4%). Three patients were lost to follow-up: two were in the 12-week treatment group and one was in the 8-week group. All of them reached end of treatment but were lost before SVR12. No relapsers were observed in either group. CONCLUSION: Eight weeks of treatment of SOF/LVD combination is equally effective and safe as 12 weeks in adolescent genotype-4 patients.

RESUMO

BACKGROUND: Hepatocellular carcinoma (HCC) is one of the most prevalent cancers worldwide. It has been widely established that the early detection of HCC enables more treatment options and translates to improved survival. AIM: To assess the diagnostic accuracy of DKK1 as a serum protein marker for HCC by examining its diagnostic sensitivity and specificity in HCC. METHODS: We analyzed data for 50 patients with hepatitis C virus (HCV) related HCC as the studied group. Twenty patients with chronic hepatitis C and 20 patients with HCV-related liver cirrhosis will serve as control group. DKK1 was measured in serum by ELISA. We used receiver operating characteristics (ROC) to calculate its diagnostic accuracy. RESULTS: We assessed serum DKK1 in 90 participants: 50 with HCC (studied group), 20 with chronic HCV infection, and 20 with liver cirrhosis (as control group). Serum concentration of DKK1 was significantly higher in HCC group and values did not differ significantly between the two control groups. We performed multivariate regression analysis using AFP level, number of focal lesions, focal lesion size and Portal vein thrombosis as an independent variable. ROC curves showed the optimum diagnostic cut off was 1.5 ng/mL (sensitivity 67.5%, specificity 89.3%). CONCLUSION: Serum DKK1 could potentially be used for early diagnosis of HCC and complement measurement of AFP in the diagnosis of HCC.

RESUMO

Data are limited regarding the role of proteinase-activated receptor-2 (PAR-2) in the esophageal mucosa in gastroesophageal reflux disease (GERD) patients. Our aim was to study PAR-2 expression and its relationship with different GERD-related clinical and pathologic parameters. Histomorphologic alterations in eosophageal mucosa in nonerosive reflux disease (NERD) and erosive reflux disease (ERD) were also, evaluated. Endoscopic biopsies of the esophageal mucosa were obtained from 94 GERD patients and 20 participants for histopathologic analysis and PAR-2 immunohistochemical staining. The present study demonstrated significantly higher PAR-2 expression in GERD patients compared with control, whereas no significant differences were seen between NERD and ERD groups. PAR-2 expression significantly correlated with histologic score (r=0.572, P<0.001) and severity of heartburn (r=0.541, P<0.001). PAR-2 expression was significantly associated with basal cell hyperplasia, and dilated intercellular spaces and inflammatory cell count (P<0.05). Histologic analysis revealed GERD-related histomorphologic alterations in the esophageal mucosa of GERD patients with significant differences (P<0.05) among groups. Total histologic score was significantly correlated with heartburn (r=0.299, P=0.025) and endoscopic severity (r=0.359, P=0.027) in NERD and ERD patients, respectively. Taken together, this study provides evidence for the major role of PAR-2 in the pathogenesis of GERD and GERD-associated mucosal alterations.

RESUMO

Primary Sjögren's syndrome (PSS) is associated with increased risk of lymphoproliferative malignancy, and B-cell non-Hodgkin lymphoma (B-NHL) is the most frequent type. To evaluate CD4+ T lymphocytes distributions in patients with (PSS) and the association of CD4+ T lymphocytopenia with the development of (B-NHL), this study included 8 (PSS) patients associated with B-NHL (group I), 50 (pSS) patients without B-NHL (group II), and 30 healthy volunteers who served as controls. The frequency of circulating CD4+ and CD8+ T lymphocytes distributions and CD4+/CD8+ T cell ratio was assessed using flow cytometry coulter EPICS-XL and compared between patients groups and controls. There was statistically significant CD4+ T lymphocytopenia in (PSS) patients with B-NHL than those without lymphoma and controls (P = 0.001). Moreover, a significant low CD4+/CD8+ T cell ratio 0.8 in group I than group II and controls (P = 0.001) was found. Significant positive correlations of CD4+ T lymphocytopenia with other risk factors (parotid swelling, vasculitis, rheumatoid factors, low complement, cryoglobulinemia) were detected. CD4+ T lymphocytopenia is associated with B-NHL developed in patients with PSS and can be considered as an important predictor of lymphoma.
