Antimullerian Hormone, a Marker of Ovarian Reserve, Is Protective Against Presence and Severity of NASH in Premenopausal Women.

BACKGROUND & AIMS: Antimüllerian hormone (AMH) is a marker of ovarian reserve with emerging data linking lower levels to some metabolic and inflammatory diseases in women. Whether AMH levels influence nonalcoholic fatty liver disease (NAFLD) is unknown. METHODS: Leveraging the NASH Clinical Research Network we determined the association of AMH levels within 6 months of liver biopsy with presence and severity of histologic measures of NAFLD in premenopausal women. Outcomes included presence of nonalcoholic steatohepatitis (NASH), presence and severity of fibrosis, and NAFLD Activity Score and its components. Logistic and ordinal logistic regression models were adjusted for age, race/ethnicity, homeostatic model assessment for insulin resistance, body mass index, dyslipidemia, polycystic ovary syndrome, estrogen-progestin use, and menstrual cyclicity. RESULTS: Median cohort age was 35 years; 73% were white and 24% Hispanic. Thirty-three percent had diabetes, 81% had obesity, and 95% had dyslipidemia. On biopsy 71% had NASH, 68% had any fibrosis, and 15% had advanced fibrosis. On adjusted analysis (n = 205), higher AMH quartiles were inversely associated with NAFLD histology including prevalent NASH (adjusted odds ratio [AOR], 0.64; 95% confidence interval [CI], 0.41-1.00), NAFLD Activity Score ≥5 (AOR, 0.52; 95% CI, 0.35-0.77), Mallory hyaline (AOR, 0.54; 95% CI, 0.35-0.82), and higher fibrosis stage (AOR, 0.70; 95% CI, 0.51-0.98). The protective effects of AMH were more pronounced among women without polycystic ovary syndrome (n = 164), including lower odds of NASH (AOR, 0.53; 95% CI, 0.32-0.90) and any NASH fibrosis (AOR, 0.54; 95% CI, 0.32-0.93). CONCLUSIONS: AMH may reflect a unique biomarker of NASH in premenopausal women and findings suggest a novel link between reproductive aging and histologic severity of NAFLD in women.

Outcomes of pregnancy in autoimmune hepatitis: A population-based study.

BACKGROUND AND AIMS: Autoimmune hepatitis (AIH) disproportionately affects young women, which may have implications in pregnancy. However, data on pregnancy outcomes in women with AIH are limited. APPROACH AND RESULTS: Using weighted discharge data from the United States National Inpatient Sample from 2012 to 2016, we evaluated pregnancies after 20 weeks gestation and compared outcomes in AIH to other chronic liver diseases (CLD) or no CLD in pregnancy. The association of AIH with maternal and perinatal outcomes was assessed by logistic regression. Among 18,595,345 pregnancies, 935 (<0.001%) had AIH (60 with cirrhosis) and 120,100 (0.006%) had other CLD (845 with cirrhosis). Temporal trends in pregnancies with AIH remained stable from 2008 to 2016 with 1.4-6.8/100,000 pregnancies per year (p = 0.25). On adjusted analysis, the odds of gestational diabetes (GDM) and hypertensive complications (pre-eclampsia, eclampsia, or hemolysis, elevated liver enzymes, low platelets) were significantly higher in AIH compared to other CLD (GDM: OR 2.2, 95% CI: 1.5-3.9, p < 0.001; hypertensive complications: OR: 1.8, 95% CI: 1.0-3.2, p = 0.05) and also compared to no CLD in pregnancy (GDM: OR: 2.4, 95% CI: 1.6-3.6, p < 0.001; hypertensive complications: OR: 2.4, 95% CI: 1.3-4.1, p = 0.003). AIH was also associated with preterm births when compared with women without CLD (OR: 2.0, 95% CI: 1.2-3.5, p = 0.01). AIH was not associated with postpartum hemorrhage, maternal, or perinatal death. CONCLUSIONS: Rates of pregnancy in women with AIH have remained stable in recent years, although AIH is associated with notable maternal and perinatal risks, such as GDM, hypertensive complications, and preterm birth. Whether these risks are influenced by steroid use and/or AIH disease activity warrants evaluation. These data support a low risk of postpartum hemorrhage and favorable survival of mothers and infants.

Awarding additional MELD points to the shortest waitlist candidates improves sex disparity in access to liver transplant in the United States.

Since the introduction of the MELD-based allocation system, women are now 30% less likely than men to undergo liver transplant (LT) and have 20% higher waitlist mortality. These disparities are in large part due to height differences in men and women though no national policies have been implemented to reduce sex disparities. Patients were identified using the Scientific Registry of Transplant Recipients (SRTR) from 2014 to 2019. Patients were categorized into five groups by first dividing into thirds by height then dividing the shortest third into three groups to capture more granular differences in the most disadvantaged patients (<166 cm). We then used LSAM to model waitlist outcomes in five versions of awarding additional MELD points to shorter candidates compared to current policy. We identified two proposed policy changes LSAM scenarios that resulted in improvement in LT and death percentage for the shortest candidates with the least negative impact on taller candidates. In conclusion, awarding an additional 1-2 MELD points to the shortest 8% of LT candidates would improve waitlist outcomes for women. This strategy should be considered in national policy allocation to address sex-based disparities in LT.

NAFLD Cirrhosis Is Rising Among Childbearing Women and Is the Most Common Cause of Cirrhosis in Pregnancy.

Rates of pregnancies affected by nonalcoholic fatty liver disease (NAFLD) in the United States have nearly tripled in the last decade and NAFLD confers increased perinatal risks, such as hypertensive complications, postpartum hemorrhage, and preterm birth.1 Rates of cirrhosis in pregnancy are also rising,2 although estimates specific to NAFLD cirrhosis are lacking. Whether NAFLD cirrhosis confers differential perinatal risks than other causes of cirrhosis in pregnancy is also unknown.

Pregnancies With Cirrhosis Are Rising and Associated With Adverse Maternal and Perinatal Outcomes.

INTRODUCTION: Cirrhosis incidence in pregnancies from outside the United States (US) is rising, although contemporary data including maternal and perinatal outcomes within the United States are lacking. METHODS: Using discharge data from the racially diverse US National Inpatient Sample, temporal trends of cirrhosis in pregnancies were compared with noncirrhotic chronic liver disease (CLD) or no CLD. Outcomes included preterm birth, postpartum hemorrhage, hypertensive complications (preeclampsia, eclampsia, and/or hemolysis, elevated liver enzymes, and low platelets syndrome), and maternal or fetal death. Logistic regression was adjusted for age, race, multiple gestation, insurance status, and prepregnancy metabolic comorbidities. RESULTS: Among 18,573,000 deliveries from 2012 to 2016, 895 had cirrhosis, 119,875 had noncirrhotic CLD, and 18,452,230 had no CLD. Pregnancies with cirrhosis increased from 2.5/100,000 in 2007 to 6.5/100,000 in 2016 (P = 0.01). On adjusted analysis, cirrhosis was associated with hypertensive complications (vs no CLD, OR 4.9, 95% confidence intervals [CI] 3.3-7.4; vs noncirrhotic CLD, OR 4.4, 95% CI 3.0-6.7), postpartum hemorrhage (vs no CLD, OR 2.8, 95% CI 1.6-4.8; vs noncirrhotic CLD, OR 2.0, 95% CI 1.2-3.5), and preterm birth (vs no CLD, OR 3.1, 95% CI 1.9-4.9; vs noncirrhotic CLD, OR 2.0, 95% CI 1.3-3.3, P ≤ 0.01). Cirrhosis was statistically associated with maternal mortality, although rarely occurred (≤ 1%). DISCUSSION: In this racially diverse, US population-based study, pregnancies with cirrhosis more than doubled over the past decade. Cirrhosis conferred an increased risk of several adverse events, although maternal and perinatal mortality was uncommon. These data underscore the need for reproductive counseling and multidisciplinary pregnancy management in young women with cirrhosis.

Proteomic analysis of TGFß-induced A549 secretome identifies putative regulators of epithelial-mesenchymal transition.

Imparting epithelial to mesenchymal transition (EMT) during cellular transformation, a major driving force behind tumor progression, is one of the notorious oncogenic activities of transforming growth factor ß (TGFß); however, the secretary factors released during TGFß-induced EMT that may have role in potentiating EMT and tumor progression are poorly known. This study was undertaken to identify such secreted protein factors from TGFß-induced A549 cells cultured in serum-free chemically defined medium (FreestyleTM ) using Matrix Assisted Laser Desorption Ionization-Time of flight/Time of flight (MALDI-TOF/TOF) mass spectrometry. We identified some of the potential factors such as ESR, ANXA2, ALDH1A, TGFß-induced protein ig-h3, and PAI-1 that were not only secreted but some were also elevated in TGFß-induced A549 cells. Interestingly, these factors are widely reported to play crucial role in EMT induction and progression, which not only validates our findings but also opens avenues for further investigation, if upon secretion they act exogenously through certain receptors to potentiate cellular signaling involved in EMT induction and tumor progression.

Low Testosterone Is Associated With Nonalcoholic Steatohepatitis and Fibrosis Severity in Men.

With rising prevalence of obesity and diabetes, nonalcoholic fatty liver disease (NAFLD) is now a leading cause of chronic liver disease. One-third of obese or diabetic men have subnormal free and bioavailable testosterone concentrations.1 Several studies have further shown low testosterone to be associated with imaging-confirmed NAFLD in men,2 although it is unknown whether low testosterone confers increased risk of more clinically relevant manifestations of NAFLD, including nonalcoholic steatohepatitis (NASH) and NASH fibrosis. We therefore aimed to evaluate the association of testosterone with histologic features of NAFLD among a representative cohort of men from the multicenter NASH Clinical Research Network (NASH CRN).

Testosterone is Associated With Nonalcoholic Steatohepatitis and Fibrosis in Premenopausal Women With NAFLD.

BACKGROUND & AIMS: Higher testosterone contributes to imaging-confirmed nonalcoholic fatty liver disease (NAFLD) in women, but whether testosterone influences their disease severity is unknown. METHODS: The association of free testosterone (free T) with nonalcoholic steatohepatitis (NASH) was determined in pre-menopausal women with biopsy-confirmed NAFLD (n = 207). Interaction testing was performed for age and free T given decline in testosterone with age, and association of aging with NASH. Regression models adjusted for abdominal adiposity, diabetes, and dyslipidemia. RESULTS: Median age was 35 yrs (interquartile range, 29-41); 73% were white, 25% Hispanic; 32% had diabetes, 93% abdominal adiposity, and 95% dyslipidemia. 69% had NASH, 67% any fibrosis, and 15% advanced fibrosis. Higher free T levels were associated with NAFLD severity in younger women (interaction P value <.02). In the youngest age quartile, free T was independently associated with NASH (odds ratio [OR], 2.3; 95% CI, 1.2-4.4), NASH fibrosis (OR, 2.1; 95% CI, 1.1-3.8), and higher fibrosis stage (OR, 1.9; 95% CI, 1.1-3.4), P value .02. In these women, the proportion with NASH steadily rose from 27% to 88%, and with NASH fibrosis rose from 27% to 81%, with higher free T quartiles (P < .01). Free T was additionally associated with abdominal adiposity among all pre-menopausal women (OR, 2.2; 95% CI, 1.2-4.1: P = .02). CONCLUSIONS: In young women with NAFLD, higher testosterone levels conferred a 2-fold higher risk of NASH and NASH fibrosis, and increased risk of abdominal adiposity, supporting a potential mechanistic link of abdominal fat on testosterone-associated liver injury. Testosterone may represent an early risk factor for NASH progression in young women, prior to their onset of more dominant, age-related metabolic risk factors.

Outcomes of Pregnant Women With Cirrhosis and Their Infants in a Population-Based Study.

BACKGROUND & AIMS: The incidence of cirrhosis is increasing among women of childbearing age. Contemporary outcomes of pregnant women with cirrhosis and their infants, as well as liver-related complications, have not been described in North America, to our knowledge. We investigated the association between cirrhosis and perinatal outcomes and evaluated perinatal liver-related events. METHODS: We performed a retrospective cohort study using population-based administrative health care data from Ontario, Canada (2000-2017). We identified pregnant women with compensated cirrhosis (n = 2022) using validated case definitions and routine mother-infant linkage; the women were matched to 10,110 pregnant women in the general population (1:5) based on birth year and socioeconomic status. Maternal and infant outcomes up to 6 weeks postpartum and liver-related complications up to 1 year postpartum were evaluated by using multivariate log-binomial regression. RESULTS: After we adjusted for demographic and metabolic risk factors, cirrhosis was independently associated with intrahepatic cholestasis of pregnancy (relative risk [RR], 10.64; 95% confidence interval [CI], 7.49-15.12), induction of labor (RR, 1.15; 95% CI, 1.03-1.28), puerperal infections (RR, 1.32; 95% CI, 1.02-1.70), preterm birth (RR, 1.60; 95% CI, 1.35-1.89), infants who were large for gestational age (RR, 1.24; 95% CI, 1.05-1.46), and neonatal respiratory distress (RR, 1.20; 95% CI, 1.02-1.42). Fewer than 2% of pregnant women with cirrhosis had liver-related complications, but these occurred in a significantly higher proportion of women with a history of hepatic decompensation (13%) than women with compensated cirrhosis (1.2%) (P < .001). CONCLUSIONS: In a population-based study, we found that cirrhosis is an independent risk factor for adverse perinatal outcomes. However, liver-related complications are rare. Multidisciplinary teams are needed to coordinate care for pregnant women with cirrhosis during pregnancy and postpartum to optimize outcomes.

Pregnancy Outcomes After Living Liver Donation: A Multi-Institutional Study.

Nearly half of living liver donors in North America are women of child-bearing age. Fetal and maternal outcomes after donation are unknown. We conducted a retrospective cohort study of female living liver donors (aged 18-50 years at donation) from 6 transplant centers. Participants were surveyed about their pregnancies and fertility. Outcomes were compared between predonation and postdonation pregnancies. Generalized estimating equations were clustered on donor and adjusted for age at pregnancy, parity, and pregnancy year. Among the 276 donors surveyed, 151 donors responded (54.7% response rate) and reported 313 pregnancies; 168/199 (68.8%) of the predonation pregnancies and 82/114 (71.9%) of the postdonation pregnancies resulted in live births, whereas 16.6% and 24.6% resulted in miscarriage, respectively. Women with postdonation pregnancies were older (32.0 versus 26.7 years; P < 0.001) and more frequently reported abnormal liver enzymes during pregnancy (3.5% versus 0.0%; P = 0.02) and delivery via cesarean delivery (35.4% versus 19.7%; P = 0.01). On adjusted analysis, there was no difference in cesarean delivery (odds ratio [OR], 2.44; 95% confidence interval [95% CI], 0.98-6.08), miscarriage (OR, 1.59; 95% CI, 0.78-3.24), combined endpoints of pregnancy-induced hypertension and preeclampsia (OR, 1.27; 95% CI, 0.36-4.49), or intrauterine growth restriction and preterm birth (OR, 0.91; 95% CI, 0.19-4.3). Of the 49 women who attempted pregnancy after donation, 11 (22.5%) self-reported infertility; however, 8/11 (72.7%) eventually had live births. Aside from increased reporting of abnormal liver enzymes and cesarean deliveries, there was no significant difference in pregnancy outcomes before and after living liver donation. One-fifth of women who attempt pregnancy after liver donation reported infertility, and although the majority went on to successful live births, further exploration is needed to understand the contributing factors. Future research should continue to monitor this patient-centered outcome across a large cohort of donors.

Adherence to pregnancy hepatitis B care guidelines in women and infants in the United States and evaluation of two interventions to improve care: A multicentre hospital-based study.

There has been an increase in hepatitis B (HBV) detection during pregnancy in the United States and an emphasis on measures to decrease mother-to-child transmission of HBV. We performed a multicentre retrospective study (2015-2018) evaluating care among all women with HBV during pregnancy. We determined rates and predictors of adherence to key maternal care measures including: (1) referral to HBV specialty care, (2) assessment of HBV DNA, and (3) initiation of antiviral therapy, and (4) rates of HBIG and HBV vaccine completion in infants. We evaluated two interventions to improve HBV care: (1) clinical decision support with best practice alert and (2) co-location of HBV care in obstetrics department. We identified 372 women with HBV during pregnancy. Patients had a median age of 33 (IQR 29, 36), were mostly of Asian (49%) or Black (36%) race, HBeAg-negative (83%) with HBV DNA ≤2000 IU/mL (65%) and maximum ALT ≤25 (66%). Regarding care measures, 62% were referred to an HBV specialist, 85% had HBV DNA checked during pregnancy and 68% with HBV DNA ≥200,000 were initiated on antiviral therapy. Co-located obstetric-liver diseases clinics appeared to improve adherence to maternal care measures. All infants received HBIG and the first HBV vaccine dose, 106 (81%) received the second, 94 (74%) received the 3rd dose, but fewer at the recommended time intervals. We identified clear gaps in adherence to HBV care measures for both mothers and infants. Co-location of HBV care in the obstetrics department shows promise in improving adherence to maternal care measures.

Non-alcoholic fatty liver disease in pregnancy is associated with adverse maternal and perinatal outcomes.

BACKGROUND & AIMS: The prevalence of non-alcoholic fatty liver disease (NAFLD) is rising in young adults, with potential implications for reproductive-aged women. Whether NAFLD during pregnancy confers more serious risks for maternal or perinatal health is unclear. METHODS: Using weighted discharge data from the US national inpatient sample, we evaluated temporal trends of NAFLD in pregnancies after 20 weeks gestation, and compared outcomes to pregnancies with other chronic liver diseases (CLDs) or no CLD. Study outcomes included preterm birth, postpartum hemorrhage, hypertensive complications (pre-eclampsia, eclampsia, and/or hemolysis, elevated liver enzymes, and low platelets syndrome), and maternal or fetal death. NAFLD prevalence was estimated by calendar year and temporal trends tested by linear regression. Outcomes were analyzed by logistic regression adjusted for age, race, multiple gestation, and pre-pregnancy diabetes, obesity, dyslipidemia and hypertension. RESULTS: Among 18,574,225 pregnancies, 5,640 had NAFLD and 115,210 had other, non-NAFLD CLD. Pregnancies with NAFLD nearly tripled from 10.5/100,000 pregnancies in 2007 to 28.9/100,000 in 2015 (p <0.001). Compared to the other groups, patients with NAFLD during pregnancy more frequently experienced gestational diabetes (7-8% vs. 23%), hypertensive complications (4% vs. 16%), postpartum hemorrhage (3-5% vs. 6%), and preterm birth (5-7% vs. 9%), all p values ≤0.01. On adjusted analysis, compared to no CLD, NAFLD was associated with hypertensive complications, preterm birth, postpartum hemorrhage and possibly maternal (but not fetal) death. CONCLUSION: The prevalence of NAFLD in pregnancy has nearly tripled in the last decade and is independently associated with hypertensive complications, postpartum hemorrhage and preterm birth. NAFLD should be considered a high-risk obstetric condition, with clinical implications for pre-conception counseling and pregnancy care. LAY SUMMARY: The prevalence of non-alcoholic fatty liver disease (NAFLD) in pregnancy has almost tripled over the past 10 years. Having NAFLD during pregnancy increases risks for both the mother and the baby, including hypertensive complications of pregnancy, bleeding after delivery, and preterm birth. Thus, pre-conception counseling is warranted with consideration of high-risk obstetric management among women with NAFLD in pregnancy.

Family Planning in Liver Transplant: Patient and Provider Knowledge and Practices.

Fertility is often impaired in adolescents and women with cirrhosis, but it is rapidly restored after liver transplantation (LT). Early and unplanned pregnancies confer increased risks to maternal, fetal, and graft health, underscoring the need for reproductive counseling. However, data on reproductive practices or counseling in the LT setting are limited. An anonymous online Qualtrics (Provo, UT) survey was sent to transplant patients and providers to gauge knowledge and practices surrounding contraception and pregnancy. Eligible participants included transplant patients aged 14-45 years and their transplant providers. Patient response was 50.0% (74/148), 14 of whom were pre-LT patients and 60 of whom were post-LT patients. Counseling occurred in 37% of patients prior to transplant and 82% after transplant. Most patients (86%) considered family planning a high priority in their transplant care. Contraception- and pregnancy-specific counseling was provided by LT providers in 60% and 44% of patients, respectively. The most desired mode of counseling by patients was in-person discussion with an LT provider (89%). Despite most post-LT patients receiving counseling, only 41% used contraception during the first year after LT, of whom 32% relied on high failure methods. Of the 31/43 (72.1%) provider responses, 96% voiced interest in additional reproductive education. Most providers (90%) correctly advised that patients delay pregnancy during the first year after LT, although misconceptions about safety of estrogen and intrauterine devices were selected by 53% and 42%, respectively. Some favored resources by providers were educational pamphlets in clinic (88%) and automated note templates to prompt family planning inquiry (72%). Transplant patients and providers have key deficiencies in their knowledge of contraception and corresponding practices. Most post-LT patients receive counseling, yet contraception practices are inadequate for preventing unplanned pregnancy. Discussion with transplant providers was the most favored counseling modality by patients, underscoring our critical role in optimizing post-LT reproductive care.

Polycystic ovary syndrome (PCOS) is associated with NASH severity and advanced fibrosis.

BACKGROUND: Polycystic ovary syndrome (PCOS) affects 10% of reproductive-aged women, and is marked by irregular menses and high androgens. PCOS is a known risk factor for imaging-confirmed steatosis, and we now aim to evaluate whether PCOS influences histologic severity of non-alcoholic fatty liver disease (NAFLD). METHODS: Retrospective study of women ages 18-45 years with biopsy-confirmed NAFLD between 2008 and 2019. Metabolic comorbidities were captured within 6 months of biopsy. Histologic features of non-alcoholic steatohepatitis (NASH) were independently evaluated by two pathologists blinded to PCOS status. RESULTS: Among 102 women meeting study criteria, 36% (n = 37) had PCOS; median age was 35 years; 27% were white, 6% black, 19% Asian and 47% reported Hispanic ethnicity. Women with PCOS had higher LDL (122 vs 102 mg/dL, P = .05) and body mass index(BMI) (38 vs 33 kg/cm2 , P < .01). NASH was present in 76% of women with PCOS vs 66% without PCOS (P = .3), and a higher proportion with PCOS had severe ballooning (32% vs 13%, P = .02), presence of any fibrosis (84% vs 66%, P = .06) and advanced fibrosis (16% vs 6%, P = .10). Adjusted for age and BMI, PCOS remained associated with severe hepatocyte ballooning (OR 3.4, 95% CI 1.1-10.6, P = .03) and advanced fibrosis (OR 7.1, 95% CI 1.3-39, P = .02). Among women with advanced fibrosis, median age was 5 years younger in those with as compared to those without PCOS (40 vs 45 years, P = .02). CONCLUSION: Polycystic ovary syndrome is independently associated with more severe NASH, including advanced fibrosis. Hepatologists should routinely inquire about PCOS in reproductive-aged women with NAFLD, and evaluate for more severe liver disease in this population.

Longer lactation duration is associated with decreased prevalence of non-alcoholic fatty liver disease in women.

BACKGROUND & AIMS: Lactation lowers blood glucose and triglycerides, and increases insulin sensitivity. We hypothesized that a longer duration of lactation would be associated with lower prevalence of non-alcoholic fatty liver disease (NAFLD), which is the leading cause of chronic liver disease in the United States. METHODS: Participants from the Coronary Artery Risk Development in Young Adults cohort study who delivered ≥ 1 child post-baseline (Y0: 1985-1986), and underwent CT quantification of hepatic steatosis 25 years following cohort entry (Y25: 2010-2011) were included (n = 844). The duration of lactation was summed for all post-baseline births, and NAFLD at Y25 was assessed by central review of CT images and defined by liver attenuation ≤ 40 Hounsfield Units after exclusion of other causes of hepatic steatosis. Unadjusted and multivariable logistic regression analyses were performed using an a priori set of confounding variables; age, race, education, and baseline body mass index. RESULTS: Of 844 women who delivered after baseline (48% black, 52% white, mean age 49 years at Y25 exam), 32% reported lactation duration of 0 to 1 month, 25% reported >1 to 6 months, 43% reported more than 6 months, while 54 (6%) had NAFLD. Longer lactation duration was inversely associated with NAFLD in unadjusted logistic regression. For women who reported >6 months lactation compared to those reporting 0-1 month, the odds ratio for NAFLD was 0.48 (95% CI 0.25-0.94; p = 0.03) and the association remained after adjustment for confounders (adjusted odds ratio 0.46; 95% CI 0.22-0.97; p = 0.04). CONCLUSIONS: A longer duration of lactation, particularly greater than 6 months, is associated with lower odds of NAFLD in mid-life and may represent a modifiable risk factor for NAFLD. LAY SUMMARY: A longer duration of breastfeeding has been associated with multiple potential health benefits for the mother including reduction in heart disease, diabetes and certain cancers. In this study we found that breastfeeding for longer than 6 months was associated with a lower risk of non-alcoholic fatty liver disease in mid-life.

Noninvasive Tests for Prognosticating Outcomes in Patients With Chronic Liver Disease in Pregnancy: Ready for Prime Time?

Rates of cirrhosis and pregnancy in women of reproductive age are increasing, making pregnancy-specific prognostic markers of disease severity increasingly important. Gonsalkorala et al. describe albumin-bilirubin score and aspartate aminotransferase-to-platelet ratio index as superior prognostic tools to the Model for End-Stage Liver Disease (MELD) score in predicting live births and gestation beyond 37 weeks in pregnant women with cirrhosis, among 165 pregnancies in women with chronic liver disease. However, further efforts are needed to identify diagnostic and prognostic tools during pregnancy, as well as to refine and implement a multidisciplinary team-centered approach to the care of women with chronic liver disease during pregnancy.

Sex Hormone-Binding Globulin Levels in Young Men Are Associated With Nonalcoholic Fatty Liver Disease in Midlife.

INTRODUCTION: Cross-sectional data note lower levels of testosterone and sex hormone-binding globulin (SHBG) levels in men with nonalcoholic fatty liver disease (NAFLD). Whether sex hormone levels in young men are predictive of later risk of NAFLD is not known. METHODS: Among men in the prospective population-based multicenter Coronary Artery Risk Development in Young Adults study (mean age 50; n = 837), we assessed whether testosterone and SHBG levels measured at study year 10 (median age 35 years) were associated with prevalent NAFLD at study year 25. NAFLD was defined using noncontrast abdominal computed tomography (CT) scan after excluding other causes of hepatic steatosis. The association of testosterone and SHBG with prevalent NAFLD was assessed by logistic regression. RESULTS: Total testosterone levels in young men were inversely associated with subsequent prevalent NAFLD on unadjusted analysis (odds ratio [OR] 0.64, 95% confidence interval 0.53-0.7, P < 0.001), although no longer significant after adjustment for year 10 metabolic covariates as well as change in metabolic covariates from years 10 to 25 (OR 0.99, 95% confidence interval 0.76-1.27). In contrast, there was a significant inverse association of SHBG with prevalent NAFLD, independent of testosterone and metabolic covariates (OR 0.68, OR 0.51-0.92, P = 0.013). On formal mediation testing, visceral adiposity was found to explain ∼41.0% (95% confidence interval 27%-73%) of the association of lower SHBG with prevalent NAFLD. CONCLUSIONS: Lower levels of SHBG in young men are associated with increase in prevalent NAFLD in middle age, independent of comprehensive metabolic risk factors. SHBG may provide a novel marker of NAFLD risk in young men.

Sex hormone levels by presence and severity of cirrhosis in women with chronic hepatitis C virus infection.

Cirrhosis is associated with hormonal dysregulation, as evidenced by secondary amenorrhoea in reproductive-aged women, and feminization of cirrhotic men. Whether hormone levels vary by severity of cirrhosis in women is not known. If identified, such changes may have important clinical relevance, particularly, as low sex hormone binding globulin (SHBG) and follicle stimulating hormone (FSH) are known to promote metabolic and cardiovascular disease in women. In a cohort of post-menopausal women with chronic hepatitis C virus (HCV) infection, we compared comprehensive sex hormone levels by presence of cirrhosis, as well as across Child-Turcotte-Pugh (CTP) class. Results: There were n = 18 cirrhotic and n = 21 noncirrhotic women with a median age of 57 years (interquartile range [IQR] 53-62). Compared to noncirrhotics, cirrhotic women had higher oestradiol (11.0 vs 6.0 pg/mL, P = 0.05) and oestrone levels (32.0 vs 8.0 ng/mL, P < 0.001), and lower sex hormone binding globulin (SHBG) (69.2 vs 155.6 nmol/L, P = 0.001), and FSH levels (4.9 vs 89.6 mIU/mL, P < 0.001). Among cirrhotic women, there was a progressive decline in FSH and SHBG and concurrent rise in oestrone levels from CTP class A to C (test of trend, P values ≤0.02). Cirrhosis is associated with lower FSH and SHBG levels in cirrhotic compared to noncirrhotic women with HCV infection. In cirrhotic women, these levels demonstrate steady decline by disease severity. Given known associations of low SHBG and FSH with cardio-metabolic disease, the clinical implications of hormonal changes by cirrhosis severity in HCV-infected women warrants investigation.
