Molecular evolution, virology and spatial distribution of HCV genotypes in Pakistan: A meta-analysis. INFECTIOUS MEDICINE 2023; 2:324-333. [PMID: 38205178 PMCID: PMC10774773 DOI: 10.1016/j.imj.2023.11.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/09/2023] [Revised: 11/09/2023] [Accepted: 11/15/2023] [Indexed: 01/12/2024]
Abstract
Background Hepatitis C, caused by the Hepatitis C Virus (HCV), is the second most common form of viral hepatitis. The geographical distribution of HCV genotypes can be quite complex, making it challenging to ascertain the most prevalent genotype in a specific area. Methods To address this, a review was conducted to determine the prevalence of HCV genotypes across various provinces and as a whole in Pakistan. The scientific literature regarding the prevalence, distribution, genotyping, and epidemiology of HCV was gathered from published articles spanning the years 1996-2020. Results Genotype 1 accounted for 5.1% of the patients, with its predominant subtype being 1a at 4.38%. The frequencies of its other subtypes, 1b and 1c, were observed to be 1.0% and 0.31% respectively. Genotype 2 had a frequency of 2.66%, with the most widely distributed subtype being 2a at 2.11% of the patients. Its other subtypes, 2b and 2c, had frequencies of 0.17% and 0.36% respectively. The most prevalent genotype among all isolates was 3 (65.35%), with the most frequent subtype being 3a (55.15%), followed by 3b (7.18%). The prevalence of genotypes 4, 5, and 6 were scarce in Pakistan, with frequencies of 0.97%, 0.08%, and 0.32% respectively. The prevalence of untypeable and mixed genotypes was 21.34% and 3.53% respectively. Estimating genotypes proves to be a productive method in assisting with the duration and selection of antiviral treatment. Different HCV genotypes can exhibit variations in their response to specific antiviral treatments. Different genotypes may have distinct natural histories, including variations in disease progression and severity. Some genotypes may lead to more rapid liver damage, while others progress more slowly. Conclusions This information can guide screening and testing strategies, helping to identify individuals at higher risk of developing severe complications. Studying the distribution of HCV genotypes in a population can provide valuable insights into the transmission dynamics of the virus.

Hepatitis B among University Population: Prevalence, Associated Risk Factors, Knowledge Assessment, and Treatment Management. Viruses 2022; 14:v14091936. [PMID: 36146743 PMCID: PMC9501279 DOI: 10.3390/v14091936] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Revised: 08/25/2022] [Accepted: 08/29/2022] [Indexed: 11/17/2022] Open
Abstract
Background: Very few studies have been reported on hepatitis B in the State of Azad Jammu and Kashmir, Pakistan, and none of them are specific to the prevalence and causes of hepatitis B spread among educational institutes. This study aimed to estimate the prevalence of hepatitis B infection and its associated risk factors among the University of AJ and K population. Methods: An observational, cross-sectional, and analytical study was conducted with 7015 students and employees. Hepatitis B was detected by rapid immunochromatographic tests (ICTs), enzyme-linked immunosorbent assay (ELISA), and real-time quantitative PCR. A questionnaire and interview method was used to assess the disease knowledge and associated risk factors with hepatitis B through Chi-square, Fisher’s exact test, and paired t-test. Results: Of the participants, 150 (2.13%) were found positive for the hepatitis B surface antigen (57.3% male and 42.7% female). Only 0.3% participants were found fully vaccinated against the hepatitis B virus. Among ethnic groups, the Syed tribe was found more prevalent for hepatitis B infection (40.6%), while use of contaminated mourning blades (95% CI: p = 0.0001) was found as an overlooked risk factor. Hepatitis preventive awareness sessions were found to be very significant (p = 0.0001). Conclusions: The study showed that an overlooked risk factor is playing a key role in the spread of HBV in a tribe living worldwide, which must be addressed globally to eradicate hepatitis B. In Pakistan, a country-wide annual HBV vaccination program should be launched to control hepatitis B.

Abstract
BACKGROUND Raman spectroscopy is an effective tool for detecting and discriminating centrifugally filtered hepatitis B virus serum and centrifugally filtered control serum. OBJECTIVES The purpose of current study is to separate high molecular weight fractions from low molecular weight fractions present hepatitis B serum to increase the disease diagnostic ability of surface enhanced Raman spectroscopy (SERS). METHODS Clinically diagnosed centrifugally filtered serum samples of hepatitis B patients are subjected for surface enhanced Raman spectroscopy (SERS) in comparison with centrifugally filtered serum samples of healthy individuals by using silver nanoparticles (Ag-NPs) as SERS substrates. Some SERS spectral features are solely observed in centrifugally filtered serum samples of hepatitis B and some SERS spectral are solely observed in centrifugally filtered serum samples of healthy individuals. The diagnostic ability of SERS is further enhanced with different statistical techniques like principal component analysis (PCA), partial least square discriminant analysis (PLS-DA) and partial least square regression analysis (PLSR) have applied. RESULTS The disease biomarkers of hepatitis B are more pronounced after their centrifugation as compared with uncentrifuged form. Statistical tools like principal component analysis (PCA) and partial least square discriminant analysis (PLS-DA) clearly differentiated centrifugally filtered serum samples of hepatitis B from centrifugally filtered serum samples of healthy individuals. Furthermore, partial least square regression analysis (PLSR) has been applied for predicting unknown viral load of centrifugally filtered serum sample of hepatitis B. CONCLUSION SERS technique along with chemometric tools have successfully differentiated centrifugally filtered serum samples of hepatitis B from centrifugally filtered serum samples of healthy individuals. The centrifugal filtration process has increased the differentiation accuracy of PLS-DA in terms of percentage 98% and regression accuracy of PLSR regression analysis in terms of RMSEP (0.30 IU/mL) of this diagnostic method as compared with that of uncentrifuged method.

Abstract
BACKGROUND According to published reports from the World Health Organization, it is estimated that more than 3% of the world's population is infected with HCV. Given the impact of various factors on the prevalence of HCV in the world's population and the lack of general statistics around the world, this study aims to review the studies conducted in this field and statistical analysis of the results of general statistical studies on the prevalence of HCV in the world population. METHODS In this study, systematic review and meta-analysis of information of the studies related to the prevalence of HCV in the world using keywords including: Prevalence, HCV, Hepatitis C, Healthy Population, Healthy subjects, and General Population in SID, MagIran, IranMedex, IranDoc, ScienceDirect, Embase, Scopus, PubMed, Web of Science (WoS) databases and Google Scholar search engine were extracted without time limit until April 2020. In order to perform the analysis of qualified studies, the model of random effects was used, and the inconsistency of studies with I2 index was investigated. Data analysis was performed with Comprehensive Meta-Analysis (Version 2). RESULTS In a study of 98 studies with a total sample size of 236,964 people in the world, the overall prevalence of HCV was 1.8% (95% CI: 1.4%-2.3%). Also, according to the subgroup analysis in different continents; the highest prevalence of HCV in the African continent was 7.1% (95% CI: 4.4-11.5%). CONCLUSION The results of this study show that the prevalence of hepatitis C in the world's population, especially in Africa, is almost high. Therefore, the officials of the World Health Organization should design measures to prevent the spread of this infection.

Abstract
Background Hepatitis B Virus (HBV) is one of the most common human infectious agents, and the mutations in its genome may cause chronic hepatitis (CH), liver cirrhosis (LC), and hepatocellular carcinoma (HCC). This study was designed to characterize the enhancer-II (Enh-II) region of X gene in HBV positive patients to assess the association of such mutations with CH, LC, and HCC. Methods HBV positive samples (N = 200) with patients’ demographic and clinical data were collected from different regions of Khyber Pakhtunkhwa (KP), Pakistan. The Enh-II region of the HBx gene was sequenced and zanalyzed for polymorphism associated with advanced liver disease. Univariate and logistic regression analyses were performed to evaluate potent mutations associated with a risk for LC and HCC. Results HBV Enh-II region sequences analysis revealed 25 different mutations. The highest frequency of mutations S101F (62.2%), A102V/R/G/I (56.25%), M103L/A (68.75%)were found in HCC, followed in LC and CH patients as 57.1%, 42.8%, 28.52% 16%, 15.2% and 18.4% respectively. H94 deletion in the α-box of the Enh-II region, associated with a high risk of HCC was found in half of the HCC patients. This deletion was present in 28.5% of LC and 6.5% of CH patients. Importantly, the high frequency of some notable mutations such as E109A/Y, A110S/K, Y111D/E, and F112L was first time reported in the entire study population. The frequencies of these mutations were high in HCC (43.75%, 37.5%, 50% and 43.75% respectively) as compared to LC (14.28%, 14.28%, 28.2% and 42.8%) and CH patients (12.8%, 15.2%, 16.8% and 16% respectively). Conclusion Mutations associated with LC and HCC are prevalent in the Enh-II region in Pakistani HBV isolates. The mutations found are alarming in CH patients as these may progress to LC and HCC in a large number of patients.

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
Hepatitis C virus (HCV) is the serious global public health burden of liver disease. Approximately 170 million people in the world are infected with (HCV). In Pakistan, where the disease has high occurrence rate. The present study envisages an up-to-date prevalence of HCV and genotypic distribution in the general population of Mardan District, Khyber Pakhtunkhwa (KP), Pakistan. The blood samples from 6,538 individuals including 3,263 males and 3,275 females were analyzed for hepatitis C surface antigen by Immuno-chromatographic test (ICT), Enzyme-linked immunosorbent assay (ELISA), and reverse transcription-polymerase chain reaction (PCR). It was found that 396 (12.13%) out of 3263 individuals contained antibodies in their blood against HCV, while among the different age groups, the highest incidences of HCV antibodies were found in the 31-40 age group (11.01%). The ICT positive samples were further screened by nested PCR to determine the existence of active HCV-RNA. It was identified that 7.11% (3263) of the total population (6538) tested was positive, among which the 461 (14.07%) females possessed antibodies in their blood against HCV. Our data showed total HCV infection in the investigated population was 5.78%. Higher percentage of HCV prevalence was detected in males than females in the age group 31-40 and 41-50. To compare the prevalence of HCV genotypes age-wise in male and female genotype 3a was found most prevalent genotype followed by 1a, 2a and 3b, respectively.

Abstract
BACKGROUND Raman spectroscopy is a promising technique to analyze the body fluids for the purpose of non-invasive disease diagnosis. OBJECTIVES To develop a surface-enhanced Raman spectroscopy (SERS) based method for qualitative and quantitative analysis of hepatitis B viral (HBV) infection from blood serum samples. METHODS Clinically diagnosed hepatitis B virus (HBV) infected serum samples of patients of different levels of viral loads have been subjected for SERS analysis in comparison with the healthy ones by using silver nanoparticles (Ag NPs) based SERS substrates. The SERS measurements were performed on blood serum samples of 11 healthy and 32 clinically diagnosed HBV patients of different viral load levels of different exponentials including (101, 102 called as low level), (103, 104 called as medium level) and (105, 108 called as high level). Furthermore, multivariate data analysis techniques, Principal Component Analysis (PCA) and Partial Least Square Regression (PLSR) were also performed on SERS spectral data. RESULTS The SERS spectral features due to biochemical changes in HBV positive serum samples associated with the increasing viral loads were established which could be employed for HBV diagnostic purpose. PCA was found helpful for the differentiation between SERS spectral data of serum samples of different levels of HBV infection and healthy individuals. PLSR model developed with standard samples of known viral loads for predicting the viral loads of blind/unknown samples with 99% predicted accuracy. CONCLUSION SERS can be employed for qualitative and quantitative analysis of HBV infection from blood serum samples.

Abstract
Academics acknowledge religiosity, spirituality and social support as socio-behavioral factors that influence patients' ability to deal with chronic illness. This study has attempted to describe empirical reality of how these factors influence patients. The sample of this study was 500 chronically ill hepatitis patients and was selected through the multistage sampling techniques. Through structured interview schedule, data were collected during the period of September 2016 to March 2017 from five most populated cities of Punjab (Pakistan). Data were analyzed through descriptive (frequency and percentage) and inferential statistics (Cronbach's alpha, Pearson correlation, and structural equation modeling). The study suggests some recommendations and suggestions to policy makers regarding the significance of religiosity, spirituality and social support as coping strategies during chronic illness. The findings illustrate that social support has more association with coping than religiosity and spirituality of the patients.

Abstract
This paper reports the genetic variability of hepatitis B virus in Pakistan population. The worldwide prevalence of hepatitis B virus is estimated to be around 350 million that causes significant mortality especially in developing countries like Pakistan. In this study, genetic diversity of HBV was checked by using preS domain of HBV. About seventy-five samples were selected for study. Among these samples nine samples showed positive results after PCR and gel analysis. These nine samples were named SBS001-SBS008. After gel purification these samples were ligated in T/A cloning vector and transformed with E. coli DH5α. After successful cloning and positive restriction analysis these samples were subjected to DNA sequencing. Sequencing results showed that eight samples (SBS002-SBS008) have a deletion of 33 nucleotides at N-terminal that is characteristics of genotype D while SBS001 belongs to genotype C. Silent mutations and amino acid changes were also searched in this highly variable region of genome. Based upon this study it was concluded that genotype D is the most common genotype in Pakistan.

Abstract
This study presents the analysis of hepatitis B virus (HBV) infection in human blood serum using Raman spectroscopy combined with pattern recognition technique. In total, 119 confirmed samples of HBV infected sera, collected from Pakistan Atomic Energy Commission (PAEC) general hospital have been used for the current analysis. The differences between normal and HBV infected samples have been evaluated using support vector machine (SVM) algorithm. SVM model with two different kernels i.e. polynomial function and Gaussian radial basis function (RBF) have been investigated for the classification of normal blood sera from HBV infected sera based on Raman spectral features. Furthermore, the performance of the model with each kernel function has also been analyzed with two different implementations of optimization problem i.e. Quadratic programming and least square. 5-fold cross validation method has been used for the evaluation of the model. In the current study, best classification performance has been achieved for polynomial kernel of order-2. A diagnostic accuracy of about 98% with the precision of 97%, sensitivity of 100% and specificity of 95% has been achieved under these conditions.

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
Abstract
Background
Pakistan is highly endemic with hepatitis B virus (HBV) and the incidence of HBV infection is rising steadily. The reasons may include poor public awareness about the transmission of HBV and HCV.
Objectives
To assess the awareness of HBV and HCV among students in nonmedical universities.
Methods
The study instrument was a structured 36 item questionnaire. After obtaining permission from the respective administrations, students were approached within their university campuses and were included by convenience sampling. The results were expressed as frequencies.
Results
Five hundred students from 5 different institutions participated in the survey, with 100 students representing each institute. Most students did not recognize the possible modes of infection of hepatitis B that include reuse of syringes (57.2%), blood transfusions (62.6%), and sexual contact (57.4%). However, most (67.8%) students correctly believe that there is a vaccination available for the prevention of HBV. Most students did not recognize the possible modes of infection of hepatitis C that include reuse of syringes (61.8%), use of intravenous drugs of addiction (71.4%), sexual contact (55.6%), and blood transfusions (55.2%) as possible modes of transmission. Most students (51.8%) incorrectly believed that there is a vaccination available for the prevention of HCV.
Conclusions
There is a prominent lack of awareness regarding the risk factors for HBV and HCV infection among the student community of nonmedical universities in Karachi, and an immediate need to conduct nationwide awareness programs to raise the awareness of HBV and HCV transmission in the Pakistani population exists.

Abstract
Background Hepatitis B virus (HBV) genotype and its role in disease progression and patients’ response to antiviral treatment, is not well studied in Pakistan. This comprehensive study was aimed to determine the distribution of HBV genotypes in Pakistan and their possible association with phases of HBV infection. Methods A total of 840 HBsAg positive samples was collected and tested for HBV DNA quantity. Samples below 100 IU/ml were excluded from the study. A total of 715 samples representing all the six parts of the country were genotyped by type specific primer PCR method. Clinical data of only 384 patients was compared as the remaining 332 were either receiving antiviral treatment or their infection phase was not confirmed. Results Genotype D was found in 509 samples (71.2 %), genotype A in 55 samples (7.7 %) and mixed infection with genotypes A and D in 124 samples (17.3 %). Genotypes B, C and E were identified in less than 1 % of the total samples. Genotype A, D and their mixture (A + D) were compared for severity of HBV infection. Significant differences were not found in distribution of HBV genotypes among different disease stages. Conclusion HBV genotype D was the predominant infection in all study areas of Pakistan followed by mixed genotypes infection (A + D) whereas genotype A has 10 times lower prevalence than genotype D. Genotypes B, C, E and F altogether make only 1.5 % of the prevalence. Genotype do not appears to show the severity of liver disease.

Abstract
Hepatitis B and C are serious public health problems worldwide. Thalassemia patients are dependent on blood transfusions throughout their life and are at high risk of viral infections. The aim of this study was to estimate the prevalence of hepatitis B/C infections and different clinical parameters in multitransfused thalassemia population. In this study, 262 multitransfused β-thalassemia patients were enrolled from the capital twin cities of Pakistan. The presence of hepatitis B virus (HBV)/hepatitis C virus (HCV), alanine aminotransferase (ALT) level, serum creatinine, serum ferritin, hepatomegaly, splenomegaly, and splenectomy were analyzed. The overall prevalence of HBV and HCV was 3.08% and 55.73%, respectively, with 100% of patients older than 20 years had HCV infection. The ALT levels among HBV- and HCV-positive thalassemia patients were 92.62 ± 41.57 U/L and 98 ± 63.65 U/L, respectively; creatinine values observed were 0.4 ± 0.35 mg/dL (for HBV) and 0.39 ± 0.24 mg/dL (for HCV), while serum ferritin levels were 6865.87 ± 1649.13 ng/dL (for HBV) and 5445.95 ± 3059.28 ng/dL (for HCV). A total of 74.8% and 82.20% of HBV- and HCV-positive patients had hepatomegaly with an average increase in liver size of 4.17 and 4.33 cm, respectively. Splenomegaly was observed in 64.9% and 67.12% of HBV- and HCV-positive patients with an average increase in spleen size of 4 and 4.46 cm, respectively. Splenectomy was observed among 14.50% and 15.75% of HBV- and HCV-infected thalassemia patients. There is a strong need to properly screen blood before transfusions to reduce the future load of viral hepatitis from Pakistan.
