RESUMO

High HBV DNA levels predispose to mother to child transmission (MTCT) of HBV. Early nucleotide analogue (NA) therapy can reduce HBV DNA and minimize MTCT. We analysed immune-metabolic profile in pregnant mothers who received NA from 2nd trimester compared with untreated mothers. In 2nd trimester, there was no difference in immune profiles between Gr.1 and Gr.2 but high viral load women had downregulated pyruvate, NAD+ metabolism but in 3rd trimester, Gr.1 had significant reduction in HBV-DNA, upregulated pyruvate and NAD with increased IFN-2αA, CD8Tcells, NK cells and decreased Tregs, IL15, IL18, IL29, TGFß3 compared to Gr.2. In Gr.1, three eAg-ve women showed undetectable DNA and HBsAg. At delivery, Gr.1 showed no MTCT, with undetectable HBV DNA, HBsAg, high CD8 and NK cells in two women. We conclude, that starting NA from second trimester, reduces HBV load and MTCT, modulates NAD, induces immunity and suggest use of NA in early gestation in future trials.

RESUMO

Debabrata BarmonOvarian cancer is the sixth most common cancer in women worldwide. Patients with ovarian carcinoma mostly present at an advanced stage with serous type of epithelial ovarian cancers, which is the most lethal of all pelvic malignancies. This study aims to critically analyze high-grade serous epithelial ovarian carcinomas in women from the Northeastern region of India and compare our data with Western literature to modify treatment strategies and improve survival outcomes. This hospital-based retrospective analysis involved data from the records of 100 women with high-grade epithelial ovarian cancer treated primarily with neoadjuvant chemotherapy followed by interval debulking surgery in the department of gynecologic oncology at a tertiary level regional cancer institute from January 2018 to December 2019. The demographic, clinical and pathological profile, and survival outcome were evaluated using descriptive statistics. The overall survival of the study population was calculated using Kaplan-Meier curves using SPSS software (version 24). The majority of women belonged to 41 to 55 years age group. At first presentation to the hospital, 89 and11% patients were in stage III and stage IV of disease, respectively. Clinically, 95% of women had ascites, and 18% had metastasis to lymph nodes. Distant metastasis to lungs and liver was present in 10 and 3% of cases, respectively. A substantial percentage (98%) of women had raised serum Ca125 > 1000 at baseline, ranging from 1,745 to 10,987 IU/mL. Almost two-thirds of the cases had partial-to-complete response to neoadjuvant chemotherapy (78%). In most of the women (72%), there was no residual disease at interval debulking surgery (R0), though 28% women had R1& R2 resection. The median overall survival time was 36 months. High-grade serous ovarian cancer is commonly seen in older age group, but its occurrence in younger population has also been observed. Early diagnosis is crucial in decreasing morbidity and mortality among these patients. Therefore, efforts should be made to identify risk factors for malignancy. Assessing each parameter of statistical information reflecting its own profile may be important for calculating the risk for the development of ovarian cancer, which can help in implementing preventive measures in the future.

RESUMO

Uterine leiomyoma with hepatic vasculopathy, specifically non-cirrhotic portal fibrosis (NCPF), has hitherto been undescribed. NCPF is characterized by elevated portal pressure sans cirrhosis and has previously not been described in association with a gynecological pathology. We report the case of a female under evaluation for a heterogeneously enhancing intrauterine mass with multiple hepatic lesions with increased uptake of fluorodeoxyglucose on positron emission analysis. Fibroscan values were increased. Histopathologic evaluations revealed a leiomyoma with liver tissue showing tubercular granulomas, thin wispy fibrotic strands, and rounded portal tracts pointed to NCPF. No evidence of malignancy was seen. Metabolic imaging may be unreliable to distinguish between benign and malignant uterine pathology and granulomatous and malignant hepatic lesions. Elastography may also be ineffective in diagnosing the etiology of liver fibrosis. Histopathological analysis hence remains essential despite noninvasive tests. Further research is required on females afflicted with NCPF to exclude a hormonal link.

RESUMO

Vertical transmission of hepatitis B virus (HBV) from the mother to the newborn often results in viral persistence. To understand mechanisms of maternofetal HBV transmission, we studied maternal immunity and peripheral blood mononuclear cell (PBMC) transcriptome in mothers and newborns. We included 50 mothers and babies who were hepatitis B surface antigen (HBsAg) positive: 22 HBV transmitting mothers (group [Gr.] I) and 28 HBV nontransmitting mothers (Gr. II) to newborns and 10 healthy mother-baby pairs (Gr. III). PBMCs were analyzed for HBV-specific dendritic cells (DCs), T cells, T follicular helper (TFh) cells, B cells, functional immune responses, and cytokine levels as well as transcriptome signatures to identify immune gene expression correlates for protective immunity. Group II mothers had lower HBsAg levels (3.82 × 103 versus 1.493 × 104; P < 0.0001) with greater HBV-specific responses of DCs, T cells, TFh cells, and B cells than Gr. I mothers. Frequencies of TFh cells were lower in Gr. I mothers, with reduced interleukin-21 (IL-21) levels, and these inversely correlated with HBV DNA levels. Cut-off levels of 9.5% and 8.93% from the receiver operating curve predicted the involvement of TFh cells and B cells in HBV transmission. Transcriptome signatures revealed that maternal gene imprints were reflected in the newborns. Genes related to DCs, TFh cells, and B cells were increased in Gr. II, and Gr. II newborns showed a boost in cellular and humoral responses after vaccination. Conclusion: In mothers infected with HBV, low serum IL-21 levels and decreased TFh-cell and plasma B-cell frequencies are associated with vertical transmission of HBV to newborns. These features are indicative of low protective maternal immunity.

RESUMO

BACKGROUND: Asialoglycoprotein receptor expression on hepatocytes has been associated with endocytosis, binding and uptake of hepatitis B virus. The role of asialoglycoprotein receptor in hepatitis B virus vertical transmission and its expression on placenta has not yet been studied. PATIENTS AND METHODS: Thirty-four HBsAg+ve and 13 healthy pregnant mothers along with their newborns were enrolled. The former were categorized into transmitting and non-transmitting mothers based on their newborns being hepatitis B surface antigen and hepatitis B virus DNA positive. Expression of asialoglycoprotein receptor and hepatitis B surface antigen in placenta and isoform of asialoglycoprotein receptor on dendritic cell in peripheral and cord blood dendritic cells were analysed using flowcytometry, immune histochemistry, immune florescence and qRT-PCR. RESULTS: Twelve HBsAg+ve mothers transmitted hepatitis B virus to their newborns whereas the rest (n = 22) did not. Hepatitis B virus-transmitting mothers showed increased expression of asialoglycoprotein receptor in trophoblasts of placenta. Immunofluorescence microscopy revealed colocalization of hepatitis B surface antigen and asialoglycoprotein receptor in placenta as well as in DCs of transmitting mothers. There was no significant difference in the expression of asialoglycoprotein receptor on peripheral blood mononuclear cells or chord blood mononuclear cells between the 2 groups. However, hepatitis B virus-transmitting mothers and their HBsAg+ve newborns showed increased mRNA levels of isoform of asialoglycoprotein receptor on dendritic cell in peripheral blood mononuclear cells. Hepatitis B virus-transmitting mothers and their HBsAg+ve newborns showed an increased expression of isoform of asialoglycoprotein receptor on dendritic cell on circulating dendritic cells compared to hepatitis B virus non-transmitting mothers and their negative newborns. CONCLUSIONS: This study revealed that increased expression of asialoglycoprotein receptor in placenta and colocalization with hepatitis B surface antigen strongly indicates its role in intrauterine transmission of hepatitis B virus. Asialoglycoprotein receptor-blocking strategy can be used for therapeutic intervention of vertical transmission.

RESUMO

BACKGROUND: Acute viral hepatitis E (AVH-E) can often result in acute liver failure (ALF) during pregnancy. microRNAs serve as mediators in drug induced liver failure. We investigated their role as a biomarker in predicting ALF due to HEV (ALF-E). METHODS: We performed next generation sequencing and subsequent validation studies in PBMCs of pregnant (P) self limiting AVH-E, ALF due to HEV (ALF-E) and compared with AVH-E in non-pregnant (NP) females and healthy controls. FINDINGS: Eleven microRNAs were significantly expressed in response to HEV infection; importantly, miR- 431, 654, 1468 and 4435, were distinctly expressed in pregnant self-limiting AVH-E and healthy females (p = 0.0005), but not in ALF-E. Sixteen exclusive microRNAs differentiated ALF-E from self limiting AVH-E in pregnant females. miR-450b which affects cellular proliferation and metabolic processes through RNF20 and SECB was predominanlty upregulated and correlated with poor outcome (ROC 0.958, p = 0.001). INTERPRETATION: Our results reveal that a specific microRNA profile can predict fatality in ALF-E in pregnancy. These microRNAs could be exploited as prognostic biomarkers and help in the development of new therapeutic interventions.

RESUMO

UNLABELLED: Acute viral hepatitis resulting due to hepatitis E viral infection (AVH-E) is often serious in pregnancy and could result in acute liver failure (ALF). The role of monocytes and macrophages (mono-macs) in the pathogenesis of AVH-E and development of ALF-E in pregnancy is unclear. We investigated the functions of mono-macs in pregnant (P), AVH-E (n = 44), ALF-E (n = 12), healthy controls (HC; n = 20) and compared with nonpregnant (NP) AVH-E (n = 10), ALF-E (n = 5), and HC (n = 10). We also recruited non-hepatitis E virus-related pregnant (P), ALF-NE (n = 5) and non-pregnant (NP), ALF-NE (n = 12) patients with ALF. Mono-macs, dendritic cell (DC) phenotypes, and Toll-like receptor (TLR) expressions were studied by flow cytometry and reverse-transcriptase polymerase chain reaction. Mono-macs functionality was determined by analyzing their phagocytic activity and reactive oxygen species (ROS) generation by using flow cytometry. Frequency of mono-macs and DCs was increased during HEV infection compared to HC (P < 0.001). Macrophages were increased (P < 0.002) in ALF-E(P) compared to ALF-NE(P). The macrophage phagocytic activity and Escherichia coli-induced ROS production was significantly impaired in ALF-E(P) compared to AVH-E(P) (P < 0.001), ALF-E(NP), and ALF-NE(P) patients (P < 0.02). TLR3 and TLR9 expression and downstream MYD88 signalling molecules IRF3 and IRF7 were significantly down-regulated in ALF-E(P) (P < 0.00) compared to AVH-E(P) and ALF-NE(P). CONCLUSION: Functionality of mono-macs is impaired in pregnant ALF-E patients compared to AVH-E(P). Reduced TLR3 and TLR7 expression and TLR downstream-signaling molecules in pregnant ALF-E patients suggests inadequate triggers for the innate immune responses contributing to development and severity of ALF-E. Studies using TLR agonists to activate mono-macs may be of use and in vitro studies should be undertaken using patient samples.

RESUMO

A large program was conducted by the Government of India to study the prevalence and profile of chronic hepatitis B virus (HBV) infection and its risk factors in pregnant women attending a tertiary care hospital in India. From September 2004 to December 2008 consecutive pregnant women attending the antenatal clinic were screened and those found positive for HBsAg were enrolled. Healthy non-pregnant women of child-bearing age, who presented for blood donation during the same period, served as controls. Women with symptoms of liver disease or those aware of their HBsAg status were excluded. Of the 20,104 pregnant women screened, 224 (1.1%) and of the 658 controls, 8 (1.2%) were HBsAg positive (P = ns). Previous blood transfusions and surgery were significant risk factors for infection with HBV. Of the women who were HBsAg positive, the ALT levels were normal in 54% of the women and HBV DNA levels were above 2,000 IU/ml in 71% of women. The median HBV DNA levels were higher in women who were HBeAg positive compared to the HBeAg negative group. The most common HBV genotype was D (84%) followed by A + D and A (8% each). In conclusion, the prevalence of HBsAg positivity among asymptomatic pregnant women in North India is 1.1% with 71% having high HBV DNA levels. These women may have a high risk of transmitting infection to their newborns.

RESUMO

Coagulopathy is an important complication associated with hepatitis E virus (HEV) infection in pregnant women. Postpartum haemorrhage (PPH) remains a serious risk while managing the labour of these women. The aim of this paper is to study the factors influencing the occurrence of PPH in pregnant women with hepatitis E infection with coagulopathy. The labours of 38 pregnant women with hepatitis E and deranged coagulation profile were followed. Factors that may predict postpartum bleeding complications in women with HEV infection and deranged coagulation profile were statistically analysed. Of 38 pregnant women with acute viral hepatitis due to HEV, 13 (34%) suffered a PPH while 25 (66%) did not. On univariate analysis low alanine aminotransferase (P = 0.016), high international normalized ratio (P = 0.003), high levels of d-dimer (P = 0.008), presence of hepatic encephalopathy (P = 0.028), intrauterine fetal death (P = 0.001) and gastrointestinal bleeding (P = 0.004) were found to predict PPH. However, on multivariate analysis the only independent variable that predicted PPH was the presence gastrointestinal (GI) bleeding (odds ratio [OR] 11.363; 95% CI: 1.003, 125; P = 0.050). Women with GI bleeding have 11 times higher risk of PPH than those without a GI bleed; however, the confidence interval is very wide. Administration of fresh frozen plasma in the peripartum period reduces the risk of PPH. In conclusion, early recognition of factors which predict the risk of PPH and timely intervention with judicious use of blood and blood components in the peripartum period can improve the outcome of pregnant women with HEV infection with deranged coagulation.

RESUMO

Pregnancy in a non-communicating rudimentary horn is rare and such a pregnancy culminating in the delivery of a live fetus is even rarer. Despite advances in ultrasonography, the accuracy of ultrasound in diagnosing rudimentary horn pregnancy at advanced gestation remains elusive. Confirmatory diagnosis is made only at laparotomy. We report a multigravidae who presented at 37 weeks with transverse lie oligoamnios and decreased perception of fetal movement since quickening. Laparotomy for placenta accreta suspected on ultrasound revealed non-communicating unruptured rudimentary horn pregnancy with a live fetus and placenta percreta. Successful extraction of a term live fetus weighing 2.7 kg with excision of the rudimentary horn was carried out.

RESUMO

BACKGROUND: Hepatitis E virus (HEV) infection is known to cause severe liver disease in pregnant women. It is unclear whether obstetric and fetal outcomes are worse in pregnant women with HEV infection than in women with other forms of viral hepatitis. OBJECTIVE: To compare maternal, obstetric, and fetal outcomes in pregnant women with acute viral hepatitis caused by HEV and other hepatitis viruses. DESIGN: Observational cohort. SETTING: Tertiary care hospital, New Delhi, India. PATIENTS: 220 consecutive pregnant women presenting with jaundice caused by acute viral hepatitis. MEASUREMENTS: Maternal mortality and medical complications, obstetric complications, deliveries, and fetal outcomes. RESULTS: Infection with HEV caused acute viral hepatitis in 60% of included women. Fulminant hepatic failure was more common (relative risk, 2.7 [95% CI, 1.7 to 4.2]; P = 0.001) and maternal mortality was greater (relative risk, 6.0 [CI, 2.7 to 13.3]; P < 0.001) in HEV-infected women than in non-HEV-infected women. Women with HEV infection were more likely than those with other forms of viral hepatitis to have obstetric complications (relative risk, 4.1 [CI, 1.7 to 10.2] for antepartum hemorrhage and 1.9 [CI, 1.3 to 2.7] for intrauterine fetal death; P < 0.001 for both) and poor fetal outcomes (relative risk, 1.2 [CI, 1.0 to 1.4] for preterm delivery [P = 0.005] and 1.8 [CI, 1.2 to 2.5] for stillbirth [P = 0.026]). LIMITATIONS: The findings may not apply to community settings, to women who are asymptomatic or have only minor symptoms, or in the setting of an HEV epidemic. CONCLUSIONS: Pregnant women with jaundice and acute viral hepatitis caused by HEV infection had a higher maternal mortality rate and worse obstetric and fetal outcomes than did pregnant women with jaundice and acute viral hepatitis caused by other types of viral hepatitis.
