Public Knowledge, Awareness, and Vaccination Rates for Hepatitis B in India: A Cross-Sectional Survey.

BACKGROUND: Hepatitis B virus (HBV) is a considerable public health concern in India, characterized by a significant number of chronically infected individuals. India falls into the category of an intermediate HBV endemic country, with approximately 40 million people chronically infected. Public awareness and knowledge about HBV are crucial for prevention, diagnosis, and treatment. This study aimed to assess the knowledge and vaccination status of the general public regarding hepatitis B in India. METHODS: An online cross-sectional survey was conducted with 3,545 participants, excluding healthcare workers and individuals below 18 years old. The survey evaluated knowledge in four domains: cause and spread of the disease (Domain A), organ affected and consequences (Domain B), treatment (Domain C), and vaccination (Domain D). The survey used a scoring scale from -20 to +22 points. Vaccination status was also assessed. RESULTS: The mean knowledge score of the respondents was 6.89 (±5.88). Only 25% of the respondents demonstrated good knowledge (score ≥12), while 31% had fair knowledge (score 6-11), 40% had poor knowledge (score 0-5), and 4% had incorrect knowledge (score <0). Males, individuals aged 18-60 years, respondents with higher education levels, and urban residents had significantly higher mean knowledge scores (p < 0.01). In the domain-specific analysis, 47% of the respondents had good knowledge in Domain B, while 43% of the respondents had good knowledge in Domains C and D. Only 17% of the respondents had good knowledge in Domain A. Overall, 22.7% of the respondents had received all three doses of the HBV vaccine, with higher vaccination rates among males, individuals aged 18-60 years, those with higher education levels, and urban residents. CONCLUSION: The study revealed limited knowledge about HBV among the general public in India. Vaccination rates were also suboptimal. Public health interventions, including educational campaigns and targeted vaccination programs, are needed to improve awareness and vaccination coverage, ultimately reducing the burden of HBV infection.

A Prospective Study of Prevalence and Predictors of Cirrhotic Cardiomyopathy and Its Role in Development of Hepatorenal Syndrome.

Background and aims: Cirrhotic cardiomyopathy (CCM) is a term used to collectively describe abnormal structural and functional changes in heart of patients with cirrhosis. The present study was undertaken to find the prevalence of CCM in patients with liver cirrhosis and its predictors. We also followed these patients to evaluate the role of CCM in the development of hepatorenal syndrome (HRS). Materials & methods: This was a prospective study carried out in department of Gastroenterology, Sir Ganga Ram hospital, New Delhi. A total of 104 patients with liver cirrhosis were included. Liver cirrhosis was diagnosed on basis of clinical, biochemical, and imaging features. CCM was defined based on echocardiography. Dobutamine stress echocardiography and hepatic venous pressure gradient (HVPG) were performed in patients who gave consent. HRS was defined as per standard criteria. Patients with CCM were followed for development of HRS. Results: Fifty (48%) patients were diagnosed with CCM. All patients had diastolic dysfunction, and none had systolic dysfunction. Median age of patients with CCM was significantly higher (59 [31-78 y] vs. 52 [24-70 y], P < 0.05). Severity of liver disease (Child Turcotte Pugh score and model for end-stage liver disease score) and portal pressures (HVPG) did not differ in patients with or without CCM. Patients with CCM did not have increased incidence of HRS at the end of 6-month follow-up study. Conclusion: The presence of CCM was not related with the severity of liver dysfunction or portal pressures. Age was a significant determinant of CCM. Diastolic cardiac dysfunction does not influence the occurrence of HRS.

Multifocal colorectal non-Hodgkin's lymphoma in a patient with ulcerative colitis: A case report.

A case of multifocal non-Hodgkin's (Diffuse large B cell type) lymphoma of colon in a patient with ulcerative colitis is described. The patient was a 69-year old male treated with azathioprine and methotrexate for ulcerative colitis for 2 years. He was admitted with loose stools and hematochezia. Colonoscopy revealed two deep ulcers in ascending colon and a large ulcer in rectum. Biopsy from both the sites revealed atypical large lymphoid cells, which were CD20 positive. A whole body PET-CT scan showed disease localized to colon with bone marrow examination showing no evidence of lymphoma. The patient was given chemotherapy cycles and recovered well.

Ideal Cure for Hepatitis B Infection: The Target is in Sight.

Hepatitis B virus (HBV) is one of the most common causes of liver cirrhosis and hepatocellular carcinoma. Despite recent strides in pharmacotherapy, complete cure of HBV infection still remains an enigma. The biggest obstacle in HBV therapy is clearance of covalently closed circular deoxyribonucleic acid (cccDNA). We discuss about the role of cccDNA in HBV life cycle, efficacy and shortcomings of currently available antivirals as well as promising novel targets to achieve ideal HBV cure.

Can Non-Selective Beta-Blockers (NSBBs) Prevent Enlargement of Small Esophageal Varices in Patients with Cirrhosis? A Meta-analysis.

BACKGROUND: Non-selective beta-blockers (NSBBs) are recommended for prophylaxis of first variceal bleeding in patients of cirrhosis with large esophageal varices. However, the data is conflicting whether NSBBs can also prevent growth of small esophageal varices to large size. AIM: To perform a meta-analysis of the randomized clinical trials comparing NSBBs with placebo for prevention of development of large esophageal varices in patients of cirrhosis with small esophageal varices. METHODS: The PubMed, EMBASE, Science Direct, and Cochrane library databases were searched for relevant papers. A meta-analysis was performed using risk ratios (RRs) with 95% confidence interval (CI) as the effect sizes. RESULTS: Overall, 314 trials were initially retrieved from the database searches, of which five randomized controlled trials were included in the meta-analysis. The incidence of development of large varices (RR = 0.91, 95%CI: 0.29-2.86; P = 0.87) was similar between NSBB and placebo groups. However, the heterogeneity among studies was significant (P < 0.01) with an I2 of 93%. The incidences of first variceal bleeding (RR = 0.72, 95%CI: 0.25-2.12; P = 0.55) and death (RR = 0.76, 95%CI: 0.50-1.15; P = 0.19) were also similar between NSBB and placebo groups; with no heterogeneity. The incidence of adverse events was significantly higher in the NSBB group compared with the placebo group (RR = 4.66, 95%CI: 1.36-15.91; P = 0.01). CONCLUSION: The results of this meta-analysis indicate that NSBBs are not effective in preventing growth of small varices and may lead to significant adverse effects. Hence, NSBBs should not be recommended for cirrhotic patients with small varices.
