Abstract
Hepatitis C is a dangerous liver disease transmitted by Hepatitis C virus (HCV). HCV constitutes an important health issue in Pakistan. In Pakistani setting HCV is found frequently and is recognized as an alarming health problem. In this cross sectional study we reviewed published data regarding the seroprevalence of hepatitis C in general community, blood donors and pregnant females and risk factors linked with its occurrence in Pakistan. Data retrieved from163 studies published from 2001 to 2022 was utilized and weighted mean was calculated. Data of 1,875,232 individuals was collected and arranged into three groups, depending upon the population type such as (1) general population, (2) pregnant women, (3) blood donors. General population (765,426) and blood donors (973,260) formed the most of population. Mean Hepatitis C virus prevalence in general public and blood donors was 16.47% and 8.2% respectively. In pregnant females (136,546) the mean frequency was 9.3%. This study exhibits that the frequency of Hepatitis C in general population, pregnant females and blood donors groups was 11.32%. The data suggested that risks factors for transmitting HCV infection in Pakistan include unsterilized needle use, blood transfusions, shaving by barbers, lack of trained staff, needle stick injuries, injection drug users, household contacts/spousal transmission, unsterilized dental and surgical Instruments, improper disposal of hospital waste, poor infra-structure and others. The frequency of HCV infection is distressing in Pakistan. Health education and awareness programs are needed for decreasing Hepatitis C infection in Pakistan. The data necessitate the implementation of preventive and remedial approaches to decrease the disease load and mortality in Pakistan.

Abstract
The number of patients with chronic liver disease (CLD) is large. The social and economic burdens due to CLD have increased. The mental health problems of patients with CLD are prominent and deserve our attention and care. This study analyzed 320 patients with CLD who were hospitalized between January 2018 and January 2020. Questionnaire surveys were used to assess mental health status, including the Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), and Symptom Checklist-90 (SCL-90). At the same time, basic data and potential related factors were collected. Data were analyzed using descriptive statistics and logistic regression. Among the 320 patients with CLD, 240 (75%) had mental health problems; among the total patients, education levels, occupations, course of disease, annual hospitalizations, complications, and nursing satisfaction were significantly different between the two groups (p < .05). The education levels and occupations of the group without mental health problems were significantly different within the group (p < .05). The SCL-90 found that the four factors with the highest scores were anxiety (ANX: 33.3%), depression (DEPR: 20.4%), somatization (SOM: 12.9%), and sleep and diet (SD: 9.6%). Logistic regression analysis showed that education levels, course of disease, annual hospitalizations, complications, and nursing satisfaction levels were independent risk factors for the mental health of patients with CLD. Model fitness was checked using the Hosmer-Lemeshow test. The receiver operating characteristic (ROC) curve showed that the area under the curve was 0.84. Patients with CLD have prominent mental health problems and experience many risk factors. It is necessary to adopt individualized psychological interventions and care to improve the quality of life of these patients.

Abstract
In Pakistan, viral hepatitis is a serious public health problem affecting millions of people. Both hepatitis B and hepatitis C infections are spreading rapidly in all provinces of Pakistan, including Sindh, because of lack of knowledge about routes of transmission, low literacy rate, reuse of syringes, piercing, and other factors. However, information about the prevalence and risk factors is inadequate. So, a general population-based study was conducted to determine the prevalence rate and risk factors of hepatitis B and hepatitis C in Nawabshah. Healthy individuals were screened for hepatitis B and hepatitis C using an immunochromatographic rapid test followed by confirmation through ELISA and PCR. Information about sociodemographic and risk factors was obtained through a pretested questionnaire. Descriptive frequencies, odds ratio, and CI were calculated using SPSS software version 23. In total, 523 participants were screened for hepatitis B and hepatitis C, among whom 232 were females and 291 were males. The overall prevalence of hepatitis C and hepatitis B was 14.3% and 6.7%, respectively. In a bivariate analysis, hepatitis B infection was significantly associated with risk factors such as hospitalization, blood transfusion, needle injury, multiple sex partners, reused syringe, dental extraction, surgery, injectable drug abuse, and shaving at barbershops. Hepatitis C infection was associated with factors including surgery, needle injury, blood transfusion, reused syringes, dental extraction, and shaving at barbershops. The increasing prevalence of hepatitis B surface antigen and hepatitis C virus in Nawabshah is a public health concern. There is dire need to implement preventive measures.

Abstract
BACKGROUND The potential link between educational level and chronic liver diseases (CLD) were explored using the mortality records of liver cirrhosis, which lack accuracy and are unable to identify the different etiological factors of liver cirrhosis. Information on the association of low educational level with the severity of CLD is lacking. AIM To evaluate the potential association linking education level to etiology and clinical stage of CLD cases. METHODS Consecutive enrolment of 11,107 subjects with CLD aged≥18 years prospectively recruited in two national surveys in 2001 and 2014 at one of the participating Italian liver units throughout the country. Subjects were pooled in two groups: low education level (less than high school) and high education level (completed high school or beyond). The association of demographic, etiological, and clinical stage of subjects with educational level was assessed using logistic regression analysis. In the analysis low educational level was the outcome variable. RESULTS A total of 11,107 subjects born in Italy (mean age 55.5 years, sex ratio 1.5) were evaluated. Multiple logistic regression analysis shows that chronic HCV infection (O.R.1,38:95%,C.I.1.23-1.55), risky alcohol intake (O.R.1.96;95%,C.I.1.73-2.21) and liver cirrhosis (O.R.1.65;95%,C.I.1.46-1.85) all resulted independently associated with less than a completed high school education. HBV infection resulted independently associated with high education level (O.R.0.74;95%,C.I.0.64-0.86), reflecting changes in HBV modes of transmission in recent decades. No association was found with CLD related to non-alcoholic fatty liver disease (O.R.1.03;95%, C.I.0.81-1.30). CONCLUSIONS These findings show an independent association linking education level with viruses and alcohol-related CLD. Low educational level is associated with the severity of CLD.

Abstract
To characterize hepatitis C virus (HCV) epidemiology in Pakistan and estimate the pooled mean HCV antibody prevalence in different risk populations, we systematically reviewed all available records of HCV incidence and/or prevalence from 1989 to 2016, as informed by the Cochrane Collaboration Handbook. This systematic review was reported following the PRISMA guidelines. Populations were classified into six categories based on the risk of exposure to HCV infection. Meta-analyses were performed using DerSimonian and Laird random-effects models with inverse variance weighting. The search identified one HCV incidence study and 341 prevalence measures/strata. Meta-analyses estimated the pooled mean HCV prevalence at 6.2% among the general population, 34.5% among high-risk clinical populations, 12.8% among populations at intermediate risk, 16.9% among special clinical populations, 55.9% among populations with liver-related conditions and 53.6% among people who inject drugs. Most reported risk factors in analytical epidemiologic studies related to healthcare procedures. Pakistan is enduring an HCV epidemic of historical proportions-one in every 20 Pakistanis is infected. HCV plays a major role in liver disease burden in this country, and HCV prevalence is high in all-risk populations. Most transmission appears to be driven by healthcare procedures. HCV treatment and prevention must become a national priority.

Abstract
PURPOSE To identify, map, and synthesize the individual-level key associations and modes of exposure for hepatitis C virus (HCV) infection in the Middle East and North Africa (MENA), the most affected region by HCV. METHODS Source of data was the MENA HCV Epidemiology Synthesis Project database, populated through systematic literature searches. Risk factors determined to be statistically significant after adjustment for confounders were extracted and categorized into key associations or modes of exposure. RESULTS In total, 329 risk factors were identified from 109 articles in 14 of 24 MENA countries. Among key associations, age was most frequently reported (n = 39; 34.2%), followed by other infections/diseases (n = 20; 17.5%), and incarceration (n = 17; 14.9%). Among modes of exposure, health care-related exposures were most frequently reported (n = 127; 59.5%), followed by injecting drug use exposures (n = 45; 20.9%), community-related exposures (n = 34; 15.8%), and sexual-related exposures (n = 8; 3.7%). Blood transfusion, hemodialysis, surgical and other medical procedures, dental work, and medical injections were identified as key health care-related exposures. CONCLUSIONS Health care appears to be the primary driver of prevalent (and possibly incident) infections in MENA, followed by injecting drug use. HCV screening should target the identified modes of exposure. Commitment to prevention should be an integral component of HCV response to achieve HCV elimination by 2030, with focus on strengthening infection control in health care facilities, improving injection safety and blood screening, and expanding harm reduction services for people who inject drugs.

Abstract
UNLABELLED Despite a combination of high Hepatitis C virus (HCV) prevalence, a large adult population and high fertility, no published estimates of the scale and contribution of vertical transmission to HCV incidence in Pakistan exist. The objective of this study was to estimate the number of new HCV infections occurring in Pakistan as a result of vertical transmission. We adapted a published mathematical model based on HCV antibody and viraemia prevalence, fertility rates, risk of HCV vertical transmission and children mortality rates to estimate the number of infections in the 2007 and 2012 birth cohorts nationally and in four subnational regions. We estimated that 19 708 (95% uncertainty interval [UI]: 15 941-23 819) children were vertically infected by HCV in 2007 and 21 676 (95% UI: 17 498-26 126) in 2012. The majority of these cases (72.9% and 72.5% in 2007 and 2012, respectively) occurred in Punjab. We estimated that vertical transmission as a mode of exposure accounted for a quarter of HCV infections among children under 5 years of age (25.2% in 2007 and 24.0% in 2012). CONCLUSION Our results showed that one in 260 children born in Pakistan in 2007 and 2012 acquired HCV vertically. While currently no interventions during pregnancy and childbirth are recommended to reduce this risk, prevention, testing and treatment strategies should be considered to reduce the burden of vertical HCV infections among young children. Other routes of transmission appear to contribute the majority of HCV infections among children and must also be clarified and urgently addressed.

Abstract
Data on the prevalence of HCV infection in Italy are often outdated and from non-urban populations. This study assessed the prevalence and risk factors for HCV infection in a large metropolitan area in southern Italy. A random 1:3 systematic sample of the adult general population of Naples was selected from three general practitioner patient registers in three different city districts. Socioeconomic indicators and risk factors for HCV infection were collected. Anti-HCV and HCV-RNA assays were performed. Logistic regression analysis was used to identify independent predictors of HCV infection. Of 1,500 randomly selected subjects, 1,315 (87.7%) participated in the study. Forty subjects (3.0%; 95%CI: 2.1-4.0) were anti-HCV-positive, with HCV-RNA detected by PCR in 31 (77.5%) of these. Anti-HCV prevalence increased with age, peaking (8.2%) in people born during the years 1945-1955. It was 1.7% in people residing in the better socioeconomic districts; but 5.7% in those residing in the district with lower socioeconomic status (P < 0.01). In multivariate analysis, age ≥60 years (OR 2.8, 95%CI: 1.3-6.1) and lower educational level (OR 3.6; 95%CI: 1.4-9.3), which is a proxy of low socioeconomic status, were the only independent predictors of the likelihood of anti-HCV positivity. Overall, 22.5% of anti-HCV positive subjects were previously unaware of their status. In the large city of Naples, infection with HCV is most common in people aged older than 60 years. Differences in socioeconomic conditions have played an important role in the spread of this infection. HCV positive subjects born during the years 1945-1955 are those who may benefit, to a greater extent, to be identified in order to receive the new effective therapy. J. Med.

Abstract
Hepatitis C virus (HCV) is endemic in Pakistan and its burden is expected to increase in coming decades owing mainly to widespread use of unsafe medical procedures. The prevalence of HCV in Pakistan has previously been reviewed. However, the literature search conducted here revealed that at least 86 relevant studies have been produced since the publication of these systematic reviews. A revised updated analysis was therefore needed in order to integrate the fresh data. A systematic review of data published between 2010 and 2015 showed that HCV seroprevalence among the general adult Pakistani population is 6.8%, while active HCV infection was found in approximately 6% of the population. Studies included in this review have also shown extremely high HCV prevalence in rural and underdeveloped peri-urban areas (up to 25%), highlighting the need for an increased focus on this previously neglected socioeconomic stratum of the population. While a 2.45% seroprevalence among blood donors demands immediate measures to curtail the risk of transfusion transmitted HCV, a very high prevalence in patients attending hospitals with various non-liver disease related complaints (up to 30%) suggests a rise in the incidence of nosocomial HCV spread. HCV genotype 3a continues to be the most prevalent subtype infecting people in Pakistan (61.3%). However, recent years have witnessed an increase in the frequency of subtype 2a in certain geographical sub-regions within Pakistan. In Khyber Pakhtunkhwa and Sindh provinces, 2a was the second most prevalent genotype (17.3% and 11.3% respectively). While the changing frequency distribution of various genotypes demands an increased emphasis on research for novel therapeutic regimens, evidence of high nosocomial transmission calls for immediate measures aimed at ensuring safe medical practices.

Abstract
Background. Hyperammonemia resulting from chronic liver disease (CLD) can potentially challenge and damage any organ system of the body, particularly the brain. However, there is still some controversy regarding the diagnostic or prognostic values of serum ammonia in patients with over hepatic encephalopathy, especially in the setting of acute-on-chronic or chronic liver failure. Moreover, the association of serum ammonia with worsening Child-Pugh grade of liver cirrhosis has not been studied. Objective. This study was conducted to solve the controversy regarding the association between hyperammonemia and cirrhosis, especially hepatic encephalopathy in chronically failed liver. Material and Methods. In this study, 171 cirrhotic patients had their serum ammonia measured and analyzed by SPSS version 16. Chi-squared test and one-way ANOVA were applied. Results. The study had 110 male and 61 female participants. The mean age of all the participants in years was 42.33 ± 7.60. The mean duration (years) of CLD was 10.15 ± 3.53 while the mean Child-Pugh (CP) score was 8.84 ± 3.30. Chronic viral hepatitis alone was responsible for 71.3% of the cases. Moreover, 86.5% of participants had hepatic encephalopathy (HE). The frequency of hyperammonemia was 67.3%, more frequent in males (N = 81, z-score = 2.4, and P < 0.05) than in females (N = 34, z-score = 2.4, and P < 0.05), and had a statistically significant relationship with increasing CP grade of cirrhosis (χ2(2) = 27.46, P < 0.001, Phi = 0.40, and P < 0.001). Furthermore, serum ammonia level was higher in patients with hepatic encephalopathy than in those without it; P < 0.001. Conclusion. Hyperammonemia is associated with both increasing Child-Pugh grade of liver cirrhosis and hepatic encephalopathy.
