Hepatitis C virus (HCV) is a serious public health problem affecting 170 million carriers worldwide. It is a leading cause of chronic hepatitis, cirrhosis, and liver cancer and is the primary cause for liver transplantation worldwide. HCV genotype 6 (HCV-6) is restricted to South China, South-East Asia, and it is also occasionally found in migrant patients from endemic countries. HCV-6 has considerable genetic diversity with 23 subtypes (a to w). Although direct sequencing followed by phylogenetic analysis is the gold standard for HCV-6 genotyping and subtyping, there are also now rapid genotyping tests available such as the reverse hybridization line probe assay (INNO-LiPA II; Innogenetics, Zwijnaarde, Belgium). HCV-6 patients present with similar clinical manifestations as patients infected with other genotypes. Based on current evidence, the optimal treatment duration of HCV-6 with pegylated interferon/ribavirin should be 48 wk, although a shortened treatment duration of 24 wk could be sufficient in patients with low pretreatment viral load who achieve rapid virological response. In addition, the development of direct-acting antiviral agents is ongoing, and they give high response rate when combined with standard therapy. Herein, we review the epidemiology, classification, diagnosis and treatment as it pertain to HCV-6.

Background: Non-alcoholic fatty liver disease (NAFLD) is increasingly recognized as a cause of chronic liver disease, often resulting in liver cirrhosis, portal hypertension, and hepatocellular carcinoma damaging outcomes. Alanine transaminase (ALT) and aspartate aminotransferase (AST) are indicators of hepatocellular injury. Several studies have demonstrated that high ALT levels are correlated with higher nonalcoholic steatohepatitis (NASH) risk. The aim was to determine the correlation of serum alanine aminotransferase and aspartate transaminase with liver stiffness in Vietnamese patients with NAFLD. Patients and Methods: The study included 18 to 80 years old patients diagnosed with fatty liver on ultrasound at the University of Medical Center (UMC) liver clinic. Liver stiffness was measured using transient elastography. The histopathological, demographic, and laboratory data of the participants were also collected. The baseline and clinical characteristics of NAFLD patients were stratified by serum ALT levels. Results: There were 138 NAFLD patients, including 82 men (59.4%) and 56 women (40.6%) (mean ± SD age of 41 ± 11 years). Liver fibrosis (F0) between the two groups showed no significant difference (p = 0.469). Similarly, no difference was found in the mild fibrosis level (F2) of the two groups of patients (p = 0.371). ALT level was significantly higher in NAFLD patients with advanced fibrosis (F3, F4) (3.2% vs 15.9%, p = 0.0013; 3.2% vs 13.2%, p = 0.0047, respectively). NAFLD patients with mild to moderate fibrosis (F1-F2) were detected at 59 U/L cut-off value with 67% sensitivity and 51% specificity. However, severe fibrosis and/or cirrhosis patients (F3-F4) had a cut-off value of 81 U/L with 53% sensitivity and 67% specificity in patients. Conclusion: Using ALT level as a marker for severe NAFLD would consider high-risk patients as mild cases, even though there is still the risk of progressive and severe hepatic disease. Our study underlines the small contribution of ALT as an independent factor for detecting NAFLD severity.

Hypertriglyceridemia induced acute pancreatitis (HTGP) was associated with increased risk of local complications, recurrent acute pancreatitis (AP), the frequency of other complications, and its high mortality as compared to other causes. Determining the factors associated with the severity of HTGP was necessary and important in the management of patients with AP. This study aims to examine the clinical and biochemical characteristics of HTGP patients, and to determine the factors associated with the severity of HTGP according to the revised Atlanta classification. This retrospective and prospective study enrolled 157 HTGP patients from January 2016 to May 2019 at Cho Ray Hospital who had serum TG levels measured within the first 48 hours of admittance with a TG concentration ≥ 1000 mg/dL and excluded other causes. The clinical features and outcomes of patients with HTGP were determined in terms of demographics, clinical symptoms, laboratory data, system complications, local complications, disease severity, and length of hospital stay. The primary outcome was the severity of HTGP as based according to the revised Atlanta classification. We evaluated the relationship between general information, clinical factors and laboratory data in the study population. There were 157 HTGP patients participated in this study. Patients with HTGP had evidence of obese or overweight range (61.2%), history of diabetes mellitus (32.5%) or undiagnosed diabetes (28.0%), history of AP (35.7%), alcohol use (23.6%), hypertension (15.9%), dyslipidemia (13.4%). The patients had typical symptoms of AP, including pancreatic abdominal pain (upper abdominal pain) (93%), nausea/vomiting (80.9%), fever (59.2%), distension abdomen (84.7%), and resistance of abdominal wall (24.8%). The severity of HTGP was significantly associated with fever, altered mental status, rapid pulse, and hypotension (P < .05). Patients with severe HTGP had significantly more pancreatic necrosis, higher values of Blood urea nitrogen and creatinine, longer prothrombin time and activated partial thromboplastin time on admission and higher CRP₄₈ than not severe HTGP (P < .05). The severity of HTGP was significantly related to clinical factors including fever, altered mental status, rapid pulse, hypotension, and pancreatic necrosis. The value of Blood urea nitrogen, creatinine, prothrombin time, and activated partial thromboplastin time at admission is higher and longer in the severe AP group with P < .05.

Introduction: The prevalence of hepatitis B virus (HBV) infection in Southeast Asia is high. Awareness and early detection are essential for timely prevention and treatment. Methodology: We examined the awareness of, knowledge about, practices and views on treatment for HBV infection in Southeast Asia. A cross-sectional survey was conducted from December 2016 to February 2017 among individuals from six nations in Southeast Asia—Myanmar, Thailand, Vietnam, Cambodia, the Philippines, and Singapore. The study population comprised healthcare and non-healthcare personnel. Results: In total, 799 healthcare personnel and 1079 non-healthcare personnel completed an online survey. The prevalence of the awareness of their own HBV infection status and risk of this regionally endemic infection was 85.6% (684/799) among healthcare personnel and 54.0% (583/1079) among non-healthcare personnel. Similarly, 85.9% of healthcare personnel and 45.5% of non-healthcare personnel had good knowledge about disease transmission, complications, and the need for treatment, and 76.6% of healthcare personnel and 39.8% of non-healthcare personnel followed good HBV infection-prevention practices. Overall, 90.6% found the idea of treatment acceptable. Awareness had a significant impact on both knowledge and practice scores among both healthcare personnel and non-healthcare personnel (p < 0.01) but without statistically significant differences in treatment acceptance between the two groups (p = 0.61). Conclusions: Awareness of HBV infection was relatively low among non-healthcare personnel in Southeast Asian populations. The provision of additional hepatitis B awareness campaigns is crucial to eliminating viral hepatitis in the region.

Background and Aim Irritable bowel syndrome (IBS) is associated with repetitive gastrointestinal symptoms that greatly reduce the patient's quality of life (QoL). Training regarding IBS‐related knowledge, medication adherence, lifestyle, and diet adjustments has been demonstrated to strengthen patient QoL. The aim of this study was to evaluate the effectiveness of an educational intervention carried out by clinical pharmacists to improve the QoL of patients with IBS. Methods Our research included data collected at the University Medical Center, Ho Chi Minh City, from April 2018 to December 2018, and was designed as a randomized controlled clinical trial. Patients with IBS were randomized into an intervention group (IG) and nonintervention group (NIG). The intervention program included training about IBS‐related knowledge, the importance of medication adherence, symptom recognition, lifestyle, and diet adjustments. Participants were followed up by monthly telephone calls. The outcome was the change in patient QoL scores (IBS‐QoL) 8 weeks after they took part in the research. Results Of 273 patients in the trial, there were 132 patients in the IG cohort and 141 in the NIG cohort. At 8 weeks, IG QoL score changes were statistically higher than those of NIG: 20.1 ± 12.1 (IG) versus 13.2 ± 13.4 (NIG). Furthermore, pharmacist intervention played an important role in increasing QoL after 8 weeks, as confirmed by multivariate regression analysis (B = 5.9; 95% confidence interval 2.4–9.4, P = 0.001). Conclusions Patient education, lifestyle, and dietary intervention, administered by clinical pharmacists, improves IBS‐QoL compared to standard medical therapy over 8 weeks.
