Premature ovarian senescence and a high miscarriage rate impair fertility in women with HCV

Kidney disease and reproductive health

Understanding the relationship between reproductive health and kidney function is important to provide holistic care for people living with kidney disease. Chronic kidney disease (CKD) has negative impacts on both male and female fertility owing to factors including inflammation, hormonal dysregulation, reduced ovarian reserve, reduced sperm quality and sexual dysfunction. However, pregnancy is achievable for most cisgender women with kidney disease, including kidney transplant recipients and patients on dialysis. CKD in pregnancy is associated with health risks to the mother and child, including increased risk of progression of kidney disease, hypertensive complications of pregnancy, and neonatal complications including fetal growth restriction, preterm birth and stillbirth. However, with appropriate pre-pregnancy counselling, fertility assessment and support, health optimization, and evidence-based antenatal care, the majority of patients will achieve a good outcome. Medication safety should be reviewed before and during pregnancy and lactation, weighing the risk of disease flare against potential adverse effects on the offspring. Important areas for further research include the optimal timing of delivery and the short- and long-term cardiovascular and renal impacts of pregnancy in patients with CKD, as well as long-term kidney and cardiovascular outcomes in their offspring.

Direct-acting antivirals in women of reproductive age infected with hepatitis C virus

Eliminating hepatitis C virus (HCV) infection in the population of women of reproductive age is important not only for the health of women themselves but also for the health of newborns. This study aimed to evaluate the implementation of this goal by analysing the effectiveness of contemporary therapy in a large cohort from everyday clinical practice along with identifying factors reducing therapeutic success. The analysed population consisted of 7861 patients, including 3388 women aged 15-49, treated in 2015-2022 in 26 hepatology centres. Data were collected retrospectively using a nationwide EpiTer-2 database. Females were significantly less often infected with HCV genotype 3 compared to males (11.2% vs. 15.7%) and less frequently showed comorbidities (40.5% vs. 44.2%) and comedications (37.2% vs. 45.2%). Hepatocellular carcinoma, liver transplantation, HIV and HBV coinfections were reported significantly less frequently in women. Regardless of the treatment type, females significantly more often reached sustained virologic response (98.8%) compared to males (96.8%). Regardless of gender, genotype 3 and cirrhosis were independent factors increasing the risk of treatment failure. Women more commonly reported adverse events, but death occurred significantly more frequently in men (0.3% vs. 0.1%), usually related to underlying advanced liver disease. We have demonstrated excellent effectiveness and safety profiles for treating HCV infection in women. This gives hope for the micro-elimination of HCV infections in women, translating into a reduced risk of severe disease in both women and their children.

Assisted Reproductive Technology Treatment Outcomes in Women With Liver Disease

INTRODUCTION

There is a need for evidence-based counseling for women with chronic liver disease (LD) who may experience impaired fertility. Currently, the literature on assisted reproductive technology (ART) treatment in women with LD has been limited to a single European case series. We evaluated ART treatment outcomes in patients with LD and compared with controls.

METHODS

The retrospective study evaluated women with and without LD who had normal ovarian reserve and underwent ART treatment in a high-volume fertility practice from 2002 to 2021.

RESULTS

We identified 295 women with LD (mean age 37.8 ± 5.2 years) who underwent 1,033 ART treatment cycles; of these women, 115 underwent 186 in vitro fertilization (IVF) cycles. Six women (2.0%) had cirrhosis, 8 (2.7%) were postliver transplantation, and 281 (95.3%) had chronic LD, with viral hepatitis (B and C) being the most prevalent. In the subgroup who underwent IVF and embryo biopsy, the median fibrosis-4 score was 0.81 (0.58-1.03), and there were no statistically significant differences in response to controlled ovarian stimulation, embryo fertilization rate, or ploidy outcome in patients with LD compared with controls. In those who subsequently underwent a single thawed euploid embryo transfer to achieve pregnancy, there were no statistically significant differences in rates of clinical pregnancy, clinical pregnancy loss, or live birth in patients with LD compared with controls.

DISCUSSION

To the best of our knowledge, this study is the largest to date to evaluate IVF efficacy in women with LD. Our study demonstrates that patients with LD have similar ART treatment outcomes compared with those without LD.

Hepatitis C Virus in Pregnancy: An Opportunity to Test and Treat

With the advent of safe and well-tolerated direct-acting antiviral (DAA) medications for hepatitis C virus (HCV), disease eradication is on the horizon. However, as the rate of HCV infection among women of childbearing potential continues to rise due to the ongoing opioid epidemic in the United States, perinatal transmission of HCV presents an increasingly difficult barrier. Without the ability to treat HCV during pregnancy, complete eradication is unlikely. In this review, we discuss the current epidemiology of HCV in the United States, the current management strategy for HCV in pregnancy, as well as the potential for future use of DAAs in pregnancy.

Hepatitis B and C in Pregnancy and Children: A Canadian Perspective

In 2016, the World Health Organization released a plan to eliminate viral hepatitis as a public health threat by 2030. For Canada to achieve the recommended decreases in HBV- and HCV-related new diagnoses and deaths, an increase in services is urgently required. Identifying those at risk of, or who have acquired HBV and HCV, remains a challenge, especially with the emergence of new priority populations such as pregnant persons and children. Importantly, prenatal, and pediatric care are times when individuals are often already engaged with the healthcare system, leading to the potential for opportunistic or co-localized care and interventions. At present, Canada may not be maximizing all available virologic tools that could lead to increases in prevention, identification, improved management, or even cure. Here, we describe the continuum of care that includes preconception, prenatal, postpartum, and pediatric stages; and identify current global and Canadian recommendations, findings, and opportunities for improvement.

Pregnancy in Chronic Liver Disease: Before and After Transplantation

Chronic liver disease poses various challenges for women of reproductive age. Cirrhosis, particularly if decompensated, and liver transplantation may impact gestation and perinatal outcomes. Tailored management of underlying liver disease is critical to optimize maternal and fetal wellbeing. Early education, timely intervention, close monitoring, and a multidisciplinary approach are key elements required to minimize complications and increase chances of a safe and successful pregnancy. In this review, we focus on the pregnancy-related implications of chronic liver disease and liver transplantation on women of reproductive age and highlight disease-specific management considerations.

The effects of hepatitis B virus infection on natural and IVF pregnancy: A meta-analysis study

BACKGROUND

Hepatitis B virus (HBV) has been considered a significant cause of human reproductive failure in different studies; however, there is a considerable disagreement on the true impacts of HBV on female reproduction. This study has evaluated the impact of HBV infection on pregnancy complications in natural pregnancy and also on pregnancy outcomes in women undergoing in vitro fertilization (IVF) treatment.

METHOD

We searched Embase, Web of Science, PubMed and Google Scholar databases to identify the potentially relevant studies. Summary odds ratio (OR) or standardized mean difference (SMD) with 95% confidence interval (CI) was applied to assess the relationship. Heterogeneity testing, sensitivity analysis and publication bias testing were also performed.

RESULTS

A total of 42 studies concerning the effect of HBV infection on the natural and IVF pregnancy were included in this study. Our meta-analysis results revealed that HBV infection had a positive correlation to gestational diabetes mellitus (GDM) [OR = 1.32 (1.17-1.48) (p < 0.01)] and preterm birth [OR = 1.26 (1.14-1.40) (p < 0.01)] in natural pregnancy; however, HBV infection was not significantly associated with decreased fertility rates among the patients who underwent IVF.

CONCLUSION

This study revealed a strong association of GDM and preterm birth with higher rates of HBV infection in pregnant women. Also, our results suggested that HBV infection in patients undergoing IVF may not negatively influence the pregnancy outcome. It may be rational to conclude that IVF might be rather a safe and effective method for HBV+ females who desire to have children.

Preeclampsia and the Risk of Pancreatitis: A Nationwide, Population-Based Cohort Study

Background

Preeclampsia is a multiple organ dysfunction during pregnancy, including hepatic, renal, and neurological dysfunction, and is defined as hypertension and proteinuria occurring after 20 weeks of pregnancy. Clinical features seen in preeclampsia are due to relatively poorly perfused placenta and maternal endothelial dysfunction. Some studies have found that preeclampsia may cause acute pancreatitis due to microvascular abnormalities and visceral ischemia. This retrospective cohort study used the Taiwanese National Health Insurance Research Databases (NHIRD) to study the relationship between preeclampsia and the risk of pancreatitis.

Methods

In total, 606,538 pregnant women were selected from the NHIRD between January 1, 1998 and December 31, 2010. They were divided into a preeclampsia cohort (n = 485,211) and a nonpreeclampsia cohort (n = 121,327). After adjusting for comorbidities that may induce pancreatitis, we analyzed and compared the incidence of pancreatitis in the two cohorts.

Results

The overall incidence of pancreatitis in the preeclampsia cohort was significantly higher than that in the control cohort (4.29 vs. 2.33 per 10,000 person-years). The adjusted HR of developing pancreatitis increased 1.68-fold (95% CI: 1.19-2.36) in the preeclampsia cohort. In addition, pregnant women with preeclampsia without comorbidities had a significantly high risk of pancreatitis (aHR = 1.83, 95% CI 1.27-2.63). The combined effect of preeclampsia and alcohol-related diseases resulted in the highest risk of pancreatitis (aHR = 43.4, 95% CI: 6.06-311.3).

Conclusion

Compared with patients without preeclampsia, the risk of pancreatitis in patients with preeclampsia is significantly increased after adjusting for demographics and comorbidities. The risk of pancreatitis is greatly increased when preeclampsia is accompanied by alcohol-related diseases, hepatitis C, gallstones, diabetes, or age of 26–35 years. Early identification and effective control of preeclampsia and the associated comorbidities can reduce the risk of pancreatitis and the associated morbidity and mortality.

Real-life use of elbasvir/grazoprevir in adults and elderly patients: a prospective evaluation of comedications used in the PITER cohort

BACKGROUND

In patients treated for HCV infection, potential drug-drug interactions (DDIs) can occur among direct-acting antiviral drugs (DAAs) and comedications used. The real-life effectiveness and safety of elbasvir/grazoprevir (ELB/GZR) among co-medicated HCV patients was evaluated.

METHODS

We prospectively evaluated consecutive patients from 15 clinical centres participating in PITER who were treated with ELB/GZR and had been followed for at least 12 weeks after treatment. Data were prospectively collected on the use of comedications (including discontinuation, dose modification and addition of drugs) and potential DDIs with DAAs.

RESULTS

Of the 356 patients with at least 12-week post-treatment follow-up (median age 67, range 50-88 years), 338 (95%) achieved sustained virological response. Of these, 219 (60%) had at least one comorbidity (median 2, range 1-6); information on comedication was available for 212 of them. Of 190 comedications used, 15 (8%) drugs were modified during ELB/GZR therapy, specifically in 9 (4%) patients they were interrupted, in 2 (1%) of whom, the comedication was interrupted before the DAA therapy because of potential DDI (that is, patients treated with carbamazepine); in 12 (6%) patients the comedications were modified in terms of dosage. In 29 (14%) patients, the comedications required monitoring when used with ELB/GZR, as well as with all available DAAs. Of the 190 drugs, 27 (14%) used in 67% of patients were free of DDIs when used with ELB/GZR, whereas they required monitoring if used with other DAA regimens.

CONCLUSIONS

The results of this prospective study support findings that ELB/GZR is effective and safe in most treated patients.

Anti-Müllerian hormone concentrations in women with chronic kidney disease

Background

Serum anti-Müllerian hormone (AMH) is a biomarker of ovarian reserve. There are limited data to guide the clinical interpretation of AMH in women with chronic kidney disease (CKD). The purpose of this study was to examine AMH concentrations in women with CKD compared with women without CKD.

Methods

We conducted a prospective cohort study of serum AMH concentrations in 163 non-pregnant women with CKD. Serum AMH concentrations were compared with age-specific AMH centiles from 887 healthy female controls.

Results

Participants included 30 women with Stage 1 CKD, 37 women with Stage 2 CKD, 26 women with Stage 3a CKD, 31 women with Stage 3b CKD and 39 women with Stages 4 and 5 CKD. The median estimated glomerular filtration rate (eGFR) was 51 (interquartile range 31–80) mL/min/1.73 m². Serum AMH concentrations were lower in all CKD stages compared with women without CKD. Women ages 20–24 years with CKD had comparable serum AMH concentrations (median 1.959 ng/mL) to women ages 35–39 years without CKD (median 1.995 ng/mL). There was no evidence that eGFR was an independent modifier of serum AMH concentrations. More than half of women with CKD (58%) were predicted to have a low response to gonadotrophin stimulation.

Conclusions

Women with CKD have a lower ovarian reserve and are predicted to have a lower ovarian response to gonadotrophin stimulation compared with women without CKD of a similar age. Women with CKD who fail to conceive within 6 months of regular unprotected intercourse should be considered for fertility assessment and intervention.

Hepatitis C

Hepatitis C is a global health problem, and an estimated 71·1 million individuals are chronically infected with hepatitis C virus (HCV). The global incidence of HCV was 23·7 cases per 100 000 population (95% uncertainty interval 21·3-28·7) in 2015, with an estimated 1·75 million new HCV infections diagnosed in 2015. Globally, the most common infections are with HCV genotypes 1 (44% of cases), 3 (25% of cases), and 4 (15% of cases). HCV transmission is most commonly associated with direct percutaneous exposure to blood, via blood transfusions, health-care-related injections, and injecting drug use. Key high-risk populations include people who inject drugs, men who have sex with men, and prisoners. Approximately 10-20% of individuals who are chronically infected with HCV develop complications, such as cirrhosis, liver failure, and hepatocellular carcinoma over a period of 20-30 years. Direct-acting antiviral therapy is now curative, but it is estimated that only 20% of individuals with hepatitis C know their diagnosis, and only 15% of those with known hepatitis C have been treated. Increased diagnosis and linkage to care through universal access to affordable point-of-care diagnostics and pangenotypic direct-acting antiviral therapy is essential to achieve the WHO 2030 elimination targets.

Hepatitis C in Pregnancy: A Unique Opportunity to Improve the Hepatitis C Cascade of Care

Hepatitis C has increasingly affected women of child-bearing age over the past few years as a result of the opioid epidemic. In this review, we discuss the effect of hepatitis C on pregnancy outcomes, effect of pregnancy on hepatitis C, as well as implications on management of hepatitis C during pregnancy.

Hepatitis C and pregnancy outcomes: a systematic review protocol

INTRODUCTION

Many women living with hepatitis C (HCV) are of childbearing age. While the risk of vertical HCV transmission has been well established, the impact of HCV on pregnancy outcomes are equivocal, with some studies reporting risks of preterm birth, low gestational weight, gestational diabetes and hypertension, while other studies report no such risks. With the shift of the HCV treatment landscape to more effective, tolerable and shorter medications, understanding pregnancy outcomes of women living with HCV are an important consideration in order to provide a baseline from which to consider the usefulness and safety of HCV treatment for this population. The objective of this systematic review will be to investigate pregnancy outcomes associated with maternal HCV infection.

METHODS AND ANALYSIS

This systematic review will incorporate articles relevant to pregnancy outcomes among women living with HCV (eg, gestational diabetes and caesarean delivery). Articles will be retrieved from academic databases including MEDLINE, EMBASE, CINAHL, clinicaltrial.gov and the Cochrane Library and hand searching of conference proceedings and reference lists. A database search will not be restricted by date, and conference abstract will be restricted to the past 2 years. The Newcastle-Ottawa Quality Assessment Scale will be used to assess the quality of the retrieved studies. Data will be extracted and scored independently by two authors. A narrative account will synthesise the findings to answer the objectives of this review.

ETHICS AND DISSEMINATION

This systematic review will synthesise the literature on the pregnancy outcomes of women living with HCV. Results from this review will be disseminated to clinical audiences, community groups and policy-makers, and may support clinicians and decision-makers in developing guidelines to promote best outcomes for this population.

Hepatitis C in Pregnancy

The prevalence of hepatitis C in pregnancy is as high as 3.6% in large cohorts. The prevalence of hepatitis C acquired by vertical transmission is 0.2% to 0.4% in the United States and Europe. Although screening is not recommended in the absence of certain risk factors, the importance of understanding hepatitis C in pregnancy lies in its association with adverse maternal and neonatal outcomes. There is potential for those infants infected by vertical transmission to develop chronic hepatitis C, cirrhosis or hepatocellular carcinoma. The risk of vertical transmission is increased when mothers are co-infected with Human Immunodeficiency Virus (HIV) or possess a high viral load. There is no clear data supporting that mode of delivery increases or reduces risk. Breastfeeding is not associated with increased risk of transmission. Premature rupture of membranes, invasive procedures (such as amniocentesis), intrapartum events, or fetal scalp monitoring may increase risk of transmission. In pregnant patients, hepatitis C is diagnosed with a positive ELISA-3 and detectable Hepatitis C Virus (HCV) RNA viral load. Infants born to HCV-infected mothers should be tested for either HCV RNA on at least two separate occasions. Although prevention is not possible, there may be a role for newer direct acting anti-viral medications in the future.
