Role of oestrogen and its receptors in HEV-associated feto-maternal outcomes.

BACKGROUND: Pregnant women infected with HEV develops adverse pregnancy outcomes like, abortions, intrauterine fetal death, still births, neonatal deaths, preterm delivery and maternal mortality. AIM: To correlate oestrogen and its receptors ESR1α and ESR2ß levels with HEV-associated feto-maternal outcomes. MATERIAL & METHODS: A total of 142 pregnant women with HEV infection and 142 pregnant controls were included in study from Department of Obstetrics & Gynaecology and Department of Medicine, Maulana Azad Medical College (MAMC) and associated Lok Nayak Hospital (LNH), New Delhi. Three millilitre of blood sample was collected in plain for quantification of oestrogen, and its receptors ESR1α and ESR2ß using commercially available third-generation ELISA kits. RESULTS: The levels of oestrogen, ESR1α and ESR2ß were considerably higher in HEV-infected pregnant women (20.11 ± 18.19 ng/mL, 10.58 ± 3.27 ng/mL, 10.42 ± 4.71 ng/mL respectively) than pregnant controls (11.74 ± 6.42 ng/mL, 9.11 ± 1.63 ng/mL, 9.01 ± 1.18 ng/mL respectively)(P < 0.0001). It was found that oestrogen levels were significantly higher in pregnant women infected with HEV who had preterm delivery, low birth weight babies and fetal loss (19.64 ± 17.60 ng/mL, 19.71 ± 17.63 ng/mL, 33.62 ± 23.20 ng/mL respectively) than who had full term delivery, average birth weight babies and live babies (11.71 ± 8.77 ng/mL, 11.99 ± 9.44 ng/mL, 16.58 ± 14.98 ng/mL respectively)(P < 0.05). A significant negative correlation was observed between baby birth weight and oestrogen levels in HEV-infected pregnant women. CONCLUSION: The high level of oestrogen plays an important role in preterm delivery, low birth weight babies and fetal mortality in pregnant women with HEV infection through placental dysfunction. Moreover, oestrogen level is a significant predictor for preterm delivery and maternal mortality and ESR2ß levels is a significant predictor for maternal mortality in pregnant women infected with HEV.

Expression analysis of apolipoproteins AI & AIV in hepatocellular carcinoma: A protein-based hepatocellular carcinoma-associated study.

Background & objectives: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer mortality. The objective of this study was to find out the differential expression of apolipoproteins (ApoAI and ApoAIV) in HCC and cases of liver cirrhosis and chronic hepatitis (controls) without HCC and to compare ApoAI and ApoAIV expression with alpha-foetoprotein (AFP), the conventional marker in HCC. Methods: Fifty patients with HCC and 50 controls comprising patients with liver cirrhosis (n=25) and chronic hepatitis (n=25) without HCC were included in this study. Total proteins were precipitated using acetone precipitation method followed by albumin and IgG depletion of precipitated protein using depletion kit. Proteins were separated by sodium dodecyl sulphate-polyacrylamide gel electrophoresis. The expression changes of ApoAI and ApoAIV were confirmed by western blotting using specific primary and secondary polyclonal antibodies followed by densitometric protein semi-quantitative estimation. ApoAI, ApoAIV and AFP were measured in the plasma samples by ELISA method. Results: Semi-quantitative densitometric image analysis of the western blot images and the comparison between HCC patients with those without HCC (control) revealed differential expression of ApoAI and ApoAIV. Levels of ApoAI were significantly higher in patients with HCC compared to controls without HCC (0.279±0.216 vs 0.171±0.091 and 0.199±0.014; P <0.001). Levels of ApoAIV were significantly lower in patients of HCC compared to controls without HCC (0.119±0.061 vs 0.208±0.07 and 0.171±0.16; P <0.01). ELISA assays of apolipoproteins (ApoAI and ApoAIV) revealed similar results of expression of ApoAI and ApoAIV as detected in western blotting densitometric image analysis. Interpretation & conclusions: Increased expression of ApoAI and decreased expression of ApoAIV in HCC patients compared to controls without HCC revealed the abnormalities in HCC. These molecules need to be studied further for their use as potential biomarkers in the future diagnostic tools along with other conventional biomarkers for screening of HCC cases. It needs further analysis in higher number of patient population.

HLA-DQA1 & DQB1 variants associated with hepatitis B virus-related chronic hepatitis, cirrhosis & hepatocellular carcinoma.

Background & objectives: Clinical outcome after hepatitis B virus (HBV) exposure varies extremely from spontaneous clearance to chronic hepatitis B and often progresses to liver cirrhosis (LC) and hepatocellular carcinoma (HCC). Host genetic factor plays an important role in the regulation of immune response. This study was aimed to investigate whether HLA class II DQA1 and DQB1 gene polymorphism were associated with chronic hepatitis B infection and in the development of HBV-related LC and HCC. Methods: DQA1 and DQB1 allele polymorphism were studied in 187 patients with HBV-related liver diseases (which included 73 chronic hepatitis B, 84 LC and 30 HCC patients) and 109 controls who had spontaneously recovered from HBV infection using polymerase chain reaction amplification with sequence-specific primers. Results: Our data suggested that DQA1*0101/2/4 [odds ratio (OR)=2.78; Pc=0.003], DQA1*0103 (OR=2.64; Pc=0.0007) and DQB1*0302/3 (OR=2.15; Pc=0.01) were associated with the protection from chronic HBV infection, whereas DQB1*0402 (OR=0.25; Pc=0.001) showed susceptible effect on chronic HBV infection. DQB1*0601 (OR=3.73; Pc=0.006) conferred protective effect from developing LC; similarly, DQB1*0302/3 (OR=5.53; Pc=0.05) and DQB1*0402 (OR=0.00; Pc=0.001) conferred protective effect from developing HCC. However, DQA1*0601 and DQB1*0503 showed susceptible effect on chronic HBV infection; these associations were no longer significant after Bonferroni correction. Interpretation & conclusions: Our results revealed HLA-DQA1*0101/2/4 - DQA1*0103 - DQB1*0302/3 and DQB1*0601 as protective and DQB1*0402 as risk alleles. The study suggests that various subtypes of HLA-DQA1 and DQB1 are associated with both HBV clearance and development of chronic HBV infections.

Down regulation of TRIF, TLR3, and MAVS in HCV infected liver correlates with the outcome of infection.

In virus-infected cells, pattern recognition receptors (PRRs) recruits their specific adaptor molecules, mitochondrial antiviral signaling protein (MAVS), TIR-domain-containing adapter-inducing interferon-ß (TRIF), and TNF receptor associated factor (TRAF6) which induces interferon. Toll-like receptor 3 (TLR3) induces activation of the NF-kappa B (NF-κB) for interferon production. The study has been designed to assess the correlation of TLR3, MAVS, TRIF, and TRAF6 outcome of HCV infection. The 46 chronic hepatitis C (CHC) patients were screened for LFT (Liver function test), HBsAg, Anti HCV, viral load, histology, and expression of TLR3, MAVS, TRIF, and TRAF6 genes. Out of 46 CHC patients, 7 were on therapy. The 12 healthy controls were screened for LFT, HBsAg, Anti HCV and gene expressions. The gene expressions were studied in liver tissue and measured using semi-quantitative analysis of Western blots. It has been observed that the expression of TRAF6 was independent of HCV infection. The expression of TRIF, TLR3, and MAVS were significantly (P < 0.05) down regulated in CHC (N = 46) compared to healthy controls (N = 12), in high viral load (N = 21) compared to low viral load (N = 25), in HAI (Histology activity index) 1-4 (N = 12), 5-8 (N = 16), 9-12 (N = 8), 13-18 (N = 5) compared to HAI 0 (N = 5) cases. The significant reduction in the expression of TRIF, TLR3, and MAVS was observed in non-responder (N = 3) compared to responder (N = 4) after treatment (P < 0.05). The HCV viral load was positively correlated with the disease severity. The down regulation of TRIF, TLR3, and MAVS expressions in CHC correlates with the disease severity and the outcome of HCV infection.

Role of HEV antigen detection in HEV-related acute viral hepatitis and acute liver failure.

Detection of HEV antigen presents as an interesting low cost, novel, and rapid diagnostic technique to ascertain HEV viremia where facilities for reverse transcriptase polymerase chain reaction (RT PCR) are sparse. This study was undertaken to assess the relative efficacy of HEV antigen detection by ELISA with currently available diagnostic tests in patients of HEV-related acute viral hepatitis (AVH) and acute liver failure (ALF). This study included 36 ALF and 64 AVH cases. HEV RNA and HEV viral load were determined by RT PCR and real time PCR, respectively. Evidence of recent HEV infection was detected in 45/64 AVH cases and 22/36 ALF cases. IgM anti-HEV antibody, HEV RNA, and HEV antigen were positive in 34/45 (75.56%), 26/45 (57.77%), and 21/45 (46.66%), in the AVH group, and 16/22 (72.72%), 14/22 (63.63%), 12/22 (54.54%) in ALF group, respectively. The concordance between HEV RNA and HEV antigen was 75.56% (P < 0.01) with κ-coefficient of 0.516 and 75.27% (P = 0.07) with κ-coefficient of 0.441 (P = 0.07) in the AVH and ALF patients, respectively, indicating moderate concordance. It was established that HEV antigen detection can be used as a valuable marker of active viremia and a cheaper surrogate to HEV RT PCR, particularly in window period, pregnant and immunocompromised patients, however, it did not correlate with severity of disease or influence the final outcome of illness in any of the study groups.

IL-18 polymorphisms in hepatitis B virus related liver disease.

Interleukine-18 (IL-18) was originally called interferon (INF-γ) inducing factor and plays a critical dual role in Th1 polarization and viral clearance. We aimed to explore whether single-nucleotide promoter polymorphisms (SNPs) are associated with the outcome of hepatitis B virus (HBV) infection. 271 HBV infected patients were recruited in this study out of these 109 were spontaneously recovered and 162 were diagnosed to be having persistent HBV infection which includes 48 chronic hepatitis, 84 liver cirrhosis, 30 HCC cases and were compared with 280 healthy controls. IL-18 promoter genotyping was performed with sequence-specific primers. The results demonstrated the significant involvement of genotype AA at position -607 in healthy controls (38.6%) when compared to cases (26.0%) (OR=0.54 (0.385-0.797)) and also associated with spontaneous clearance (37.6%) compared to persistent HBV infections (17.9%) (OR=2.76 (1.582-4.832)). Whereas, genotype CC at position -607 in cases (18.0%) when compared to healthy controls (6.7%) (OR=3.03 (1.734-5.303)) also associated with persistent HBV infections (24.1%) compared to spontaneous clearance (9.2%) (OR=0.31 (0.151-0.67)). And genotype GC at position -137 in cases (49.5%) compared to healthy controls (38.5%) (OR=1.55 (1.11-2.18)). Whereas, genotype GG at position -137 in healthy controls (56.8%) compared to cases (45.4%) (OR=0.63 (0.451-0.885)). No significant difference at position -137 was observed between spontaneous clearance and persistent HBV infections. These polymorphisms of the IL-18 gene promoter region at position -607 and -137 could be associated with different outcomes of HBV infection. The people with allele A at position -607 may be protected against HBV infection; moreover AA genotype is associated with spontaneous clearance.

Evidence of extrahepatic replication of hepatitis E virus in human placenta.

The incidence and severity of hepatitis E virus (HEV) infection in pregnant women is high in developing countries. Transplacental transmission of HEV in the third trimester of pregnancy has been found to be associated with high fetal mortality. Based on this evidence and in the absence of reports on HEV replication in extrahepatic sites, this study was carried out to investigate if HEV replication occurs in the placenta of infected mothers. The study included 68 acute viral hepatitis (AVH) and 22 acute liver failure (ALF) pregnant patients. Viral RNA was extracted from blood and placenta. HEV replication in placenta was confirmed by a replicative negative-strand-specific reverse transcriptase PCR. Viral load was estimated by real-time PCR. Immunohistochemical studies were also carried out for in situ detection of HEV in placental tissue sections. Replicative HEV RNA was detectable only in the placenta in ALF and AVH cases and not in blood samples. Positive staining of placental tissue sections with HEV antibody against the viral structural protein ORF3 was observed. HEV replication in placenta also correlated with fetal and maternal mortality in ALF patients. It is demonstrated for the first time that HEV replication occurs in human placenta and that placenta may be a site of extrahepatic replication of HEV in humans.

Association of pregnancy outcome with cytokine gene polymorphisms in HEV infection during pregnancy.

Hepatitis E virus (HEV) infection is associated with high maternal and fetal mortalities. The aim of the study was to find cytokine gene polymorphisms in relation to HEV infection during pregnancy. A total of 262 pregnant and 208 non-pregnant women with hepatitis, 262 healthy pregnant and 208 non-pregnant women as controls. The study group were pregnant and non-pregnant women with HEV infection, not infected with HEV and controls. Genotyping was carried out by PCR-RFLP and ARMS-PCR methods. The frequencies of TNF-α -308 A allele & AA genotype, IFN-γ +874 T allele & TT genotypes were significantly higher in pregnant women with HEV infection compared to other groups. The frequency of TGF-ß1 codon 10 +869 T allele &TT genotype and codon 25 +915 G allele & GG genotype were significantly higher in pregnant women compared to non-pregnant women with HEV infection. The frequency of IL-6-174 GG genotype was significantly higher in pregnant women with HEV infection compared to not infected with HEV and controls. Cytokine gene polymorphisms shows association with preterm delivery (TNF-α -308 AA, IFN-γ +874 AA, TGF-ß1 codon 10 +869 TT & codon 25 GG genotypes), low birth weight (TNF-α -308 GG & IL-6 -174 CC genotypes), fetal loss (IL-6-174 CC genotype), and small for date (IL-6-174 CC & TGF-ß1 codon 10 +869 TC genotypes) of HEV infected pregnant women compared to not infected with HEV and controls. These findings suggest that cytokines gene polymorphisms were found to be associated with pregnant women with HEV infection and adverse pregnancy outcome.

Association of cytokines in hepatitis E with pregnancy outcome.

AIMS: The aim of this study was to evaluate tumour necrosis factor-alpha (TNF-α), interleukin (IL)-6, interferon gamma (IFN-γ) and transforming growth factor-beta1 (TGF-ß1) in hepatitis E infection during pregnancy and its relation with pregnancy outcome. METHODS: A total of 272 pregnant and 219 non-pregnant women with hepatitis and 262 age and gestational age matched healthy pregnant women and 208 age matched, healthy non-pregnant women were evaluated on the basis of history, clinical examination, liver function profile. Serological tests of hepatitis A, B, C and E and cytokines using commercially available (ELISA) kits. The patients with hepatitis E were further evaluated for viral load by Real Time PCR. All these were followed till delivery for pregnancy outcome. RESULTS: HEV viral load in acute viral hepatitis (AVH) and fulminant hepatic failure (FHF) of pregnant women were comparatively higher than non-pregnant women. Significantly higher levels of TNF-α, IL-6, IFN-γ and TGF-ß1 were present in HEV infected pregnant women compared to non-pregnant women and controls. TNF-α, IL-6 and IFN-γ had significant positive correlation with viral load, serum bilirubin and prothrombin time in pregnant women. Higher levels of all four cytokines were found in pregnant women with HEV infection having adverse pregnancy outcome compared to that of pregnant women with non-HEV infection and controls. CONCLUSION: In conclusion, severity of HEV infection and associated adverse pregnancy outcome might be mediated by cytokine in pregnancy.

Novel molecular alterations in the ORF 2 capsid gene of hepatitis E virus in patients with acute liver failure in North India.

Hepatitis E virus (HEV) is evolving as a major global threat to public health, including in developed countries. We partially sequenced the ORF 2 capsid protein genes of HEV genomes from patients with acute liver failure, including pregnant women in the northern part of India. Five unique synonymous substitutions and one non-synonymous substitution, along with a novel mutation, P259S, in the capsid gene, were identified that might be associated with the poor outcome in the patients. Phylogenetic analysis revealed that the isolates belonged to genotype 1 with subtype 1a. The significance of these findings for disease pathogenicity needs to be investigated further.

Efficacy of long-term albumin therapy in the treatment of decompensated cirrhosis.

BACKGROUND AND AIMS: Decompensated liver cirrhosis has a poor prognosis, with a median overall survival of two to four years, which is worse than for many oncological disorders. These patients are highly susceptible to infections due to increased systemic inflammation leading to kidney failure and death. The aim was to study the efficacy of albumin in reducing episodes of decompensation, preventing bacterial infection, kidney dysfunction and mortality. METHOD: Study involved patients with Child B or C cirrhosis with an albumin level below 3.0 g/dL, who were administered 20% human albumin weekly with standard medical treatment (SMT) for three months or till serum albumin levels were 4.0 g/dL (whichever is earlier) and compared with age and sex-matched controls who received only SMT. The primary end-point was six-month mortality and the secondary end-points were reduction in infections, kidney dysfunction, ascites recurrence, hepatic encephalopathy (HE), gastrointestinal (GI) bleed and complications of cirrhosis. RESULTS: From September 2021 to January 2023, 88 cases and 86 controls were taken and followed up for six months. Overall, six-month survival was not statistically significant between groups (95.1% vs. 91.9%; p = 0·330). The incidence of recurrence of ascites (34.09% vs. 59.3%, p < 0.001), kidney dysfunction (6.8% vs. 24.4%, p < 0.001), HE (15.9% vs, 37.2%, p = 0.015), spontaneous bacterial peritonitis (SBP) (3.4% vs 17.4%, p = 0.002) and non-SBP infections (7.9% vs. 18.6%, p = 0.038) were significantly less in cases as compared with controls; however, GI bleed (14.8% vs. 17.4%, p = 0.632) was not statistically significant. CONCLUSION: Long-term human albumin acts as a disease-modifying treatment in patients with decompensated cirrhosis.

2023 Update of Indian National Association for Study of the Liver Consensus on Management of Intermediate and Advanced Hepatocellular Carcinoma: The Puri III Recommendations.

Hepatocellular carcinoma (HCC) presents significant treatment challenges despite considerable advancements in its management. The Indian National Association for the Study of the Liver (INASL) first published its guidelines to aid healthcare professionals in the diagnosis and treatment of HCC in 2014. These guidelines were subsequently updated in 2019. However, INASL has recognized the need to revise its guidelines in 2023 due to recent rapid advancements in the diagnosis and management of HCC, particularly for intermediate and advanced stages. The aim is to provide healthcare professionals with evidence-based recommendations tailored to the Indian context. To accomplish this, a task force was formed, and a two-day round table discussion was held in Puri, Odisha. During this event, experts in their respective fields deliberated and finalized consensus statements to develop these updated guidelines. The 2023 INASL guidelines offer a comprehensive framework for the diagnosis, staging, and management of intermediate and advanced HCC in India. They represent a significant step forward in standardizing clinical practices nationwide, with the primary objective of ensuring that patients with HCC receive the best possible care based on the latest evidence. The guidelines cover various topics related to intermediate and advanced HCC, including biomarkers of aggressive behavior, staging, treatment options, and follow-up care.

Etiological and molecular profile of hepatocellular cancer from India.

Hepatocellular carcinoma (HCC) cases are underreported in India. Our study was designed to investigate the etiological profile of HCC cases in India and compare with global incidence. The study included 348 HCC and 375 chronic liver disease cases without HCC as controls. Samples were screened for hepatitis B virus (HBV)/hepatitis C virus (HCV) infections using enzyme-linked immunosorbent assay and polymerase chain reaction (PCR). HBV-DNA and HCV-RNA genotyping was performed by PCR-restriction fragment length polymorphism. All cases were also assessed for other possible risk factors of HCC. Among HCC cases, 62.6% were positive for HBV, 26.7% for HCV and 3.2% had coinfection. Around 17% of HCC cases had aflatoxin-B1 exposure. HBV genotype D (odds ratio, OR = 1.76) and mixed genotypes (OR = 6.86) had higher risk of HCC development. The risk of HCC was twofold (OR = 2.26) in patients with high HBV-DNA levels. Moreover, our findings were unable to establish a clear differential effect of HCV genotype (OR = 1.48) and high viral load (OR = 1.21) on HCC development. In India, HBV is the major risk factors, whereas alcohol, smoking and diabetes are nonsignificantly associated. Asian countries such as Hong Kong and Taiwan also had high incidence of HBV-related HCC. Contrarily, countries from Europe and USA reported HCV as predominant cause of HCC. Further, aflatoxin could be a possible risk of HCC in the population. However, in comparison to the countries such as China and Taiwan (high Aflatoxin exposure), the aflatoxin level is relatively low in our patients. High HBV-DNA levels and HBV/D increased the risk of HCC. However, neither genotype nor virus loads of HCV affected prognosis of HCC patients in our study.

Does high viral load of hepatitis E virus influence the severity and prognosis of acute liver failure during pregnancy?

The incidence and mortality in pregnant women with acute liver failure caused by hepatitis E virus (HEV) is high. Data on the viral load of HEV during pregnancy are limited. The study was designed to determine the viral load of HEV and its association with the disease severity in patients with acute liver failure. A total of HEV related 163 patients with acute liver failure which included 105 pregnant, 46 non-pregnant women and girls and 12 men and 730 patients with acute viral hepatitis which comprised of 220 pregnant women; 282 non-pregnant women and girls and 228 men were included. Viral load was measured by real-time PCR. Comparison was made between the pregnant and non-pregnant women. HEV RNA was detectable in 265 patients (142 pregnant; 75 non-pregnant and 48 men) and 104 patients with acute liver failure (64 pregnant, 34 non-pregnant and 6 men). The viral load of HEV in pregnant women with acute liver failure and acute viral hepatitis was significantly higher 129,984.0 ± 103,104.17 and 768.92 ± 1,105.40 copies/ml, respectively compared to the non-pregnant women which was 189.2 ± 225 and 12.73 ± 7.8 copies/ml (P < 0.0001). The viral load of HEV was also significantly higher in the pregnant patients with acute liver failure compared to the pregnant women with acute viral hepatitis and also men (P < 0.0001). High viral load of HEV during pregnancy could be one of the factors responsible for the severity of the infection during pregnancy.

Serum tumor necrosis factor-alpha level in hepatitis E virus-related acute viral hepatitis and fulminant hepatic failure in pregnant women.

AIM: The host response in hepatitis E virus (HEV)-related liver disease of pregnant women is unclear. This study was carried out to evaluate the serum concentration of tumor necrosis factor (TNF)-α in HEV-related acute viral hepatitis (AVH) and fulminant hepatic failure (FHF) in pregnant women in relation to pregnancy outcome. METHODS: The study included 262 pregnant and 158 non-pregnant women with jaundice. There were 160 healthy asymptomatic pregnant women and 124 healthy asymptomatic non-pregnant women as controls. The jaundiced patients were classified as AVH or FHF. Serum TNF-α level was assayed by commercially available enzyme-linked immunoassay kits. RESULTS: A significantly higher level of TNF-α was observed in HEV-infected pregnant women than non-HEV pregnant women (P < 0.001). TNF-α level was significantly higher in AVH and FHF of HEV-infected pregnant women compared with AVH and FHF of HEV infected non-pregnant women (P = 0.036 and P = 0.010, respectively). The HEV-infected pregnant FHF expired group had significantly higher levels of TNF-α than the non-pregnant FHF expired group (P = 0.025). TNF-α levels were significantly higher in AVH of HEV-infected pregnant women than healthy pregnant controls (P < 0.001). Higher TNF-α levels were observed in HEV-infected women having preterm delivery and low birthweight newborns compared with non-HEV and healthy pregnant women. CONCLUSION: Higher serum concentration of TNF-α observed in HEV infected AVH and FHF pregnant cases shows that pregnancy with HEV infection increases TNF-α secretion. TNF-α may be an important factor in the outcomes of pregnancy due to HEV infection.

To evaluate the prevalence of spontaneous portosystemic shunts in decompensated cirrhosis patients and its prognostic significance.

INTRODUCTION: Spontaneous portosystemic shunts (SPSS) are frequent in liver cirrhosis and their prevalence increases as liver function deteriorates, probably as a consequence of worsening portal hypertension, but without achieving an effective protection against cirrhosis complications. This study was conducted to detect the prevalence of portosystemic shunts in liver cirrhosis patients and analyze its prognostic role. METHOD: We conducted a prospective observational study, where 92 patients with decompensated cirrhosis were evaluated based on history, physical examination, biochemical tests and abdominal computed tomography (CT) angiography findings. A follow-up was done after six months for the development of cirrhosis-related complications. RESULTS: Of the 92 cirrhotic patients, 57.6% had SPSS (large SPSS + small SPSS) detected by multi-detector computed tomographic angiography. Overall, we found large SPSS in 24 (26.1%) patients, small SPSS in 29 (31.5%) patients and no shunt in 39 (42.4%) patients. Among the shunts, the splenorenal shunt is the most frequent type (25, 27.2%) followed by the paraumbilical shunt (20.7%). Previous decompensating events, including hepatic encephalopathy, ascites, spontaneous bacterial peritonitis and gastrointestinal bleed, were experienced more frequently by the large SPSS group followed by the small SPSS and without SPSS groups. Regarding follow-up, decompensating episodes of hepatic encephalopathy developed more frequently in patients with large SPSS (41.7%) than in patients with small SPSS (24.1%) followed by patients without SPSS (12.8%). CONCLUSION: In summary, all cirrhotic patients should be studied with radiological imaging to detect the presence of portosystemic shunts. In several cases, patients with large SPSS had a more impaired liver function and more frequent complications of portal hypertension. So, these patients would probably benefit from a closer surveillance and more intensive therapy.

Altered expression of endosomal Toll-like receptors and HBeAg seropositivity may act synergistically towards the vertical transmission of HBV.

PROBLEM: Hepatitis B is one of the leading causes of mortality in India. Despite the mass vaccination programme, the burden of the infection is still increasing due to its vertical transmission. Asymptomatic nature of hepatitis B virus (HBV) infection owing to immune tolerance among pregnant women is a major issue in this regard. METHOD OF STUDY: As such, this study aims to investigate the potential role of altered Toll-like receptor (TLR) expression (TLR-3, 7 and 9) along with peripheral blood HBeAg status in attaining differential cord blood (CB) HBV DNA status. RESULT: Expression analysis reveals an overall downregulation of expression with mean ± SD value 1.14 ± 1.05, 0.86 ± 0.5 and 0.71 ± 0.4 (TLR 3, 7 and 9, respectively) upon comparison with healthy women. Further stratification based on CB HBV DNA status; the downregulation of expression was found to be significantly (p < .05) associated with positive CB HBV DNA status apart from peripheral HBeAg status. One hundred percent HBeAg positive parturiting women exhibit positive CB HBV DNA. Pearson's correlation analysis reveals a positive correlation between CB HBV DNA status and altered TLR expression, HBeAg status and mother HBV DNA status and as such can be associated with the potential risk of HBV vertical transmission. CONCLUSION: This study suggests that the downregulation of TLR 3, 7 and 9 may be a risk factor for potential vertical transmission of HBV.

Hepatitis C virus related hepatocellular carcinoma: a case control study from India.

Infection with hepatitis C virus (HCV) is a major risk factor for hepatocellular carcinoma (HCC) in India. The study was designed to investigate the clinical and molecular profiles of HCV related HCC cases in Indian patients. In a prospective study, 68 HCV related HCC, 55 HCV related chronic hepatitis, and 68 HCV related patients with cirrhosis were included. Glutathione S-transferase gene polymorphism was analyzed in all the cases. The sex ratios were 5.18:1, 1.39:1, and 0.83:1 with mean age of 50.57 ± 12.47, 39.41 ± 13.34, and 46.08 ± 15.06 years, respectively, in three groups. Amongst the HCV related HCC cases seen in India, 49.2% (30 out of 68) were with Okuda stage I while 34.4% (21 out of 68) cases were classified as stage II. Older age, poor standards of living, HCV genotype 4, smoking, and null genotypes of GST were the risk factors associated significantly with the development of HCC. In 55.9% cases (38 out of 68) the size of the tumor was ≥5 cm while in 38.2% cases (26 out of 68) the size was between 2 and 5 cm, indicating an advanced stage of the disease at presentation.
