ABSTRACT

Spontaneous bacterial peritonitis (SBP) is a well-recognized clinical entity with a poor prognosis. In comparison, the prevalence, microbiological flora, and prognostic significance of bacterascites (BA) (the presence of organism on culture but ascitic PMN <250 cells/mm³) is largely unknown. We, therefore, assessed the prognosis and predictors of outcome in patients with BA in comparison with those with SBP. Ascitic fluid cultures from consecutive patients with cirrhosis from 2008 to 2018 were reviewed retrospectively, and patients with SBP and BA were identified. Baseline demographic, laboratory, and microbiological data were collated and analyzed as prognostic indicators, and clinical outcomes were recorded. Patients were censored at the time of LT, death, or last follow-up. For this study 176 and 213 cases of SBP and BA, respectively, were identified and included. Patients with SBP had significantly higher Model for End-Stage Liver Disease (MELD) ( p =<0.01), peripheral blood WCC ( p < 0.01), and higher rates of Enterobacteriaceae ( p < 0.01) and multi-drug resistant pathogens ( p < 0.01). Survival at 1 and 3 months was lower in patients with SBP ( p < 0.01) when compared with BA but at 6 months and beyond, no significant difference remained. After the exclusion of deaths within 30 days of presentation, survival between SBP and BA was equivocal at all time points. Mortality was substantially higher across all MELD groupings for both SBP and BA when compared with the predicted mortality calculated by the MELD score alone. BA has a negative impact on patient survival above that predicted by the MELD score. It has similar impact to SBP on patient survival beyond 1 month suggesting it should be seen as a poor prognostic marker and prompt consideration of LT where appropriate. Further studies evaluating the role of secondary prophylaxis in this group are required.

ABSTRACT

Human leukocyte antigen (HLA) matching is not routinely performed for liver transplantation as there is no consistent evidence of benefit; however, the impact of HLA mismatching remains uncertain. We explored the effect of class I and II HLA mismatching on graft failure and mortality. A total of 1042 liver transplants performed at a single center between 1999 and 2016 with available HLA typing data were included. The median follow-up period was 9.38 years (interquartile range 4.9-14) and 350/1042 (33.6%) transplants resulted in graft loss and 280/1042 (26.9%) in death. Graft loss and mortality were not associated with the overall number of mismatches at HLA-A, HLA-B, HLA-C, HLA-DR, and HLA-DQ loci. However, graft failure and mortality were both increased in HLA mismatching on graft failure and mortality the presence of one (p = 0.004 and p = 0.01, respectively) and two (p = 0.01 and p = 0.04, respectively) HLA-A mismatches. Elevated hazard ratios for graft failure and death were observed with HLA-A mismatches in univariate and multivariate Cox proportional hazard models. Excess graft loss with HLA-A mismatch (138/940 [14.7%] mismatched compared with 6/102 [5.9%] matched transplants) occurred within the first year following transplantation (odds ratio 2.75; p = 0.02). Strikingly, transplants performed at a single all grafts lost due to hepatic artery thrombosis were in HLA-A-mismatched transplants (31/940 vs. 0/102), as were those lost due to sepsis (35/940 vs. 0/102). In conclusion, HLA-A mismatching was associated with increased graft loss and mortality. The poorer outcome for the HLA-mismatched group was due to hepatic artery thrombosis and sepsis, and these complications occurred exclusively with HLA-A-mismatched transplants. These data suggest that HLA-A mismatching is important for outcomes following liver transplant. Therefore, knowledge of HLA-A matching status may potentially allow for enhanced surveillance, clinical interventions in high-risk transplants or stratified HLA-A matching in high-risk recipients.

ABSTRACT

BACKGROUND AND AIMS: Alcohol use disorders (AUD) cause 7.2% of UK hospital admissions/year. Most are not managed by hepatologists and liver disease may be missed. We used the Enhanced Liver Fibrosis (ELF) test to investigate prevalence and associations of occult advanced liver fibrosis in AUD patients not known to have liver fibrosis. METHODS: Liver fibrosis was assessed using ELF in prospective patients referred to the Royal Free Hospital Alcohol Specialist Nurse (November 2018-December 2019). Known cases of liver disease were excluded. Patient demographics, blood tests, imaging data and alcohol histories recorded. Advanced fibrosis was categorised as ELF ≥ 10.5. RESULTS: The study included 99 patients (69% male, mean age 53.1 ± 14.4) with median alcohol intake 140 units/week (IQR 80.9-280), and a mean duration of harmful drinking of 15 years (IQR 10-27.5). The commonest reason for admission was symptomatic alcohol withdrawal (36%). The median ELF score was 9.62, range 6.87-13.78. An ELF score ≥ 10.5 was recorded in 28/99 (29%) patients, of whom 28.6% had normal liver tests. Within previous 5-years, 76% had attended A&E without assessment of liver disease. The ELF score was not associated with recent alcohol intake (p = 0.081), or inflammation (p = 0.574). CONCLUSION: Over a quarter of patients with AUD had previously undetected advanced liver fibrosis assessed by ELF testing. ELF was not associated with liver inflammation or recent alcohol intake. The majority had recent missed opportunities for investigating liver disease. We recommend clinicians use non-invasive tests to assess liver fibrosis in patients admitted to hospital with AUD.

ABSTRACT

BACKGROUND AND AIM: Mortality of alcohol-related liver disease (ArLD) is increasing, and liver fibrosis stage is the best mortality predictor. Non-invasive tests (NITs) are increasingly used to detect fibrosis, but their value as prognostic tests in chronic liver disease, and in particular in ArLD, is less well recognized. We aimed to describe the prognostic performance of four widely used NITs (Fibrosis 4 test [FIB4], Enhanced Liver Fibrosis [ELF] test, FibroScan, and FibroTest) in ArLD. METHODS: Applying systematic review methodology, we searched four databases from inception to May 2020. Inclusion/exclusion criteria were applied to search using Medical Subject Heading terms and keywords. The first and second reviewers independently screened results, extracted data, and performed risk-of-bias assessment using Quality in Prognosis Studies tool. RESULTS: Searches produced 25 088 articles. After initial screening, 1020 articles were reviewed independently by both reviewers. Eleven articles remained after screening for eligibility: one on ELF, four on FibroScan, four on FIB4, one on FIB4 + FibroScan, and one on FibroTest + FIB4. Area under the receiver operating characteristic curves for outcome prediction ranged from 0.65 to 0.76 for FibroScan, 0.64 to 0.83 for FIB4, 0.69 to 0.79 for FibroTest, and 0.72 to 0.85 for ELF. Studies scored low-moderate risk of bias for most domains but high risk in confounding/statistical reporting domains. The results were heterogeneous for outcomes and reporting, making pooling of data unfeasible. CONCLUSIONS: This systematic review returned 11 papers, six of which were conference abstracts and one unpublished manuscript. While the heterogeneity of studies precluded direct comparisons of NITs, each NIT performed well in individual studies in predicting prognosis in ArLD (area under the receiver operating characteristic curves >0.7 in each NIT category) and may add value to prognostication in clinical practice.

ABSTRACT

BACKGROUND: People living with human immunodeficiency virus (PLWH) are at increased risk of cirrhosis and esophageal varices. Baveno VI criteria, based on liver stiffness measurement (LSM) and platelet count, have been proposed to avoid unnecessary esophagogastroduodenoscopy (EGD) screening for esophageal varices needing treatment (EVNT). This approach has not been validated in PLWH. METHODS: PLWH from 8 prospective cohorts were included if they fulfilled the following criteria: (1) compensated advanced chronic liver disease (LSM >10 kPa); (2) availability of EGD within 6 months of reliable LSM. Baveno VI (LSM <20 kPa and platelets >150 000/µL), expanded Baveno VI (LSM <25 kPa and platelets >110 000/µL), and Estudio de las Hepatitis Víricas (HEPAVIR) criteria (LSM <21 kPa) were applied to identify patients not requiring EGD screening. Criteria optimization was based on the percentage of EGDs spared, while keeping the risk of missing EVNT <5%. RESULTS: Five hundred seven PLWH were divided into a training (n = 318) and a validation set (n = 189). EVNT were found in 7.5%. In the training set, Baveno VI, expanded Baveno VI, and HEPAVIR criteria spared 10.1%, 25.5%, and 28% of EGDs, while missing 0%, 1.2%, and 2.2% of EVNT, respectively. The best thresholds to rule out EVNT were platelets >110 000/µL and LSM <30 kPa (HIV cirrhosis criteria), with 34.6% of EGDs spared and 0% EVNT missed. In the validation set, HEPAVIR and HIV cirrhosis criteria spared 54% and 48.7% of EGDs, while missing 4.9% and 2.2% EVNT, respectively. CONCLUSIONS: Baveno VI criteria can be extended to HEPAVIR and HIV cirrhosis criteria while sparing a significant number of EGDs, thus improving resource utilization for PLWH with compensated advanced chronic liver disease.

ABSTRACT

Patients with compensated advanced chronic liver disease (cACLD) can safely avoid screening endoscopy with a platelet count >150 × 109 cells/L and a liver stiffness measurement (LSM) <20 kPa (Baveno VI criteria). However, the total number of avoided endoscopies using this rule is relatively low. We aimed at expanding the Baveno VI criteria and validating them in additional cohorts. Patients from the Anticipate cohort (499 patients with cACLD of different etiologies) were used to study the performance of different thresholds of platelets and LSM for the identification of patients at very low risk (<5%) of having varices needing treatment (VNT). The new criteria (Expanded-Baveno VI) were validated in two additional cohorts from London (309 patients) and Barcelona (117 patients). The performance of the new criteria by etiology of cACLD was also assessed. The best new expanded classification rule was platelet count >110 × 109 cells/L and LSM <25 kPa. This was validated in the two additional cohorts. Overall, the Expanded-Baveno VI criteria would potentially spare 367 (40%) endoscopies (21% with Baveno VI criteria) with a risk of missing VNT of 1.6% (95% confidence interval, 0.7%-3.5%) in patients within the criteria and 0.6% (95% confidence interval, 0.3%-1.4%) in the overall population of 925 patients evaluated. The Expanded-Baveno VI criteria performed well in patients with cACLD with hepatitis C virus and alcoholic and nonalcoholic steatohepatitis. CONCLUSION: The new Expanded-Baveno VI criteria spare more endoscopies than the original criteria with a minimal risk of missing VNT in most of the main etiologies of cACLD.

ABSTRACT

Pregnancy associated liver diseases affect up to 3% of pregnant women and are the most frequent cause of liver dysfunction in pregnancy. When severe, they are associated with significant morbidity and mortality for both mother and infant. A rapid evaluation to distinguish them from non-pregnancy related liver dysfunction is essential, in order to facilitate appropriate management. Liver disease unrelated to pregnancy can present de novo in pregnancy, or pregnancy can occur in women with preexisting liver pathology (Table 1). Research and subsequent advances in medical care have resulted in improved but still not satisfactory maternal and fetal outcomes. In this review we provide an overview of the liver diseases specific to the pregnant state and an update on their pathogenesis, treatment and outcomes. The risks of pregnancy in women with pre-existent liver pathology is detailed and recent advances in our understanding of specific risks and outcomes are discussed.

ABSTRACT

BACKGROUND & AIMS: The Baveno VI guidelines propose that cirrhotic patients with a liver stiffness measurement (LSM) <20kPa and a platelet count >150,000/µl can avoid screening endoscopy as their combination is highly specific for excluding clinically significant varices. The aim of the study was to validate these criteria. METHODS: Transient elastography data was collected from two institutions from 2006-2015. Inclusion criteria were a LSM ⩾10kPa and an upper gastrointestinal endoscopy within 12months, with a diagnosis of compensated chronic liver disease. Exclusion criteria were porto-mesenteric-splenic vein thrombosis and non-cirrhotic portal hypertension. Varices were graded as low risk (grade <2) or high risk (grade ⩾2). RESULTS: The study included 310 patients (169 (55%) hepatitis C, and 275 (89%) Child-Pugh A). Varices were present in 23% cases, with 5% prevalence of high risk varices. Overall 102/310 (33%) met the Baveno VI criteria. Within this group 11% had varices and 2% had high risk varices, representing 2/15 (13%) of all high risk varices. The Baveno VI criteria gave a sensitivity 0.87, specificity 0.34, positive predictive value 0.06, negative predictive value 0.98, positive likelihood ratio 1.31 and negative likelihood ratio 0.39. The AUROC for LSM and platelet count combined was 0.746. CONCLUSIONS: The Baveno VI criteria performed well correctly identifying 98% of patients who could safely avoid endoscopy. LAY SUMMARY: This study examines the effectives of a recent set of guidelines published by the Baveno VI conference, which states that patients with chronic liver disease and a low liver stiffness (<20kPa) and high platelet count (>150) are at low risk of having varices and do not need a screening endoscopy. Varices are a complication of cirrhosis, confer a risk of serious bleeding, and can be diagnosed and treated by endoscopy. Our study reviewed the clinical records of patients who have had liver stiffness scans and endoscopy over a 9-year period at two hospitals. The results show that only about 2% of patients who meet the Baveno VI criteria will be miss-classified as not having varices.

ABSTRACT

Liver transplantation (LT) in patients with portopulmonary hypertension (PoPH) has historically resulted in unpredictable and often poor outcomes. The United Kingdom experience for the period 1992-2012 is reported in this article. A retrospective analysis of patients, preoperatively fulfilling the PoPH European Respiratory Society Task Force on Pulmonary-Hepatic Vascular Disorders diagnostic criteria was conducted across all UK LT centers. Data collection included comorbidities, use of preoperative and postoperative pharmacotherapy, patient survival, and cause of death. To enable survival stratification, PoPH was classified as mild, moderate, or severe based on mean pulmonary pressure of <35 mm Hg, 35-49 mm Hg, and ≥50 mm Hg, respectively. Of 127 patients reported to have PoPH, just 28 fulfilled the diagnostic criteria (14 mild, 9 moderate, 5 severe). Twenty (71.4%) patients were male with median age and Model for End-Stage Liver Disease of 50 years (range, 23-62 years) and 18 (range, 6-43), respectively. Twelve (42.9%) patients died within 5 years of LT. The majority of deaths (10 of 12; 83%) occurred within the first 6 months after LT, aetiologies of which included right heart failure (n = 3), progressive PoPH (n = 2), and sepsis (n = 2). Of those receiving preoperative pharmacotherapy (n = 8), 5 are currently alive and were classified as mild to moderate PoPH. Both severe PoPH patients optimized preoperatively with pharmacotherapy died within a year of LT. Development of effective vasodilatory therapies in the setting of pulmonary arterial hypertension has led to a dramatic improvement in patient survival. The available data indicate that in this era of pharmacotherapy, PoPH in isolation no longer represents a valid consideration to transplant. Liver Transplantation 22 1637-1642 2016 AASLD.

ABSTRACT

Reports of pregnancy in liver transplantation (LT) patients have largely favorable outcomes. Concerns remain with regards to maternal and graft risk, optimal immunosuppression (IS), and fetal outcomes. We review all post-LT pregnancies at our center with regard to the outcomes and safety for the patient, graft, and fetus. A total of 117 conceptions occurred in 79 patients. Median age at conception was 29 years. Maternal complications included graft loss (2%), acute cellular rejection (ACR; 15%), pre-eclampsia/eclampsia (15%), gestational diabetes (7%), and bacterial sepsis (5%). ACR was significantly more common in those women who conceived within 12 months of LT (P = 0.001). The live birth rate was 73%. Prematurity occurred in 26 (31%) neonates, and 24 (29%) neonates were of low or very low birth weight. IS choice (cyclosporine versus tacrolimus) had no significant effect on pregnancy outcomes and complications. No congenital abnormalities occurred, and only 1 child born at 24 weeks had delayed developmental milestones. In conclusion, pregnancy following LT has a favorable outcome in the majority, but severe maternal risks remain. Patients should be counseled with regard to the above information so informed decisions can be made, and pregnancy must be considered high risk with regular monitoring by transplant clinicians and specialist obstetricians.

ABSTRACT

There has long been evidence that hepatitis C can lead to persistent infection in a high proportion of infected individuals, and can progress to chronic liver disease, cirrhosis and hepatocellular carcinoma (HCC). The transition from acute to chronic hepatitis C is usually sub-clinical. Accurate studies of the time course for clearance of acute hepatitis C are difficult to carry out because of the silent onset of the acute disease. The likelihood of spontaneous HCV resolution is associated with several genetic factors, including IL28B inheritance and the DQB1*0301 allele of the major histocompatibility complex class II. Most data suggest that resolution in the acute phase without progression to chronic disease is not accompanied by significant disease, but minor histological lesions have been observed in anti-HCV positive, HCV RNA negative individuals. The risk of reinfection remains a possibility after clearance of acute hepatitis C. High rates of sexually-transmitted infection are being reported in HIV positive men who have sex with men (MSM). Chronic infection with HCV is the leading cause of end-stage liver disease, hepatocellular carcinoma (HCC) and liver related death in the Western world. The natural history of the chronic disease remains incompletely defined. It is generally a slowly progressive disease characterized by persistent hepatic inflammation, leading to the development of cirrhosis in approximately 10-20% of patients over 20-30 years of HCV infection. However, the published data indicate varying progression rates to cirrhosis. Overall, once cirrhosis has developed there is a 1-5% annual risk of HCC and a 3-6% annual risk of hepatic decompensation. Following an episode of decompensation the risk of death in the following year is between 15% and 20%. The high number of chronically infected individuals, the burden of disease, and the absence of a vaccine indicates that treatment will form part of the disease control but the impact, effectiveness and outcomes of treatment in various groups remain uncertain. Several studies and meta-analysis have concluded that eradication of HCV with antiviral therapy reduces the risk of HCC in patients with chronic hepatitis C, independent of fibrosis stage, but the risk is not eliminated.

ABSTRACT

BACKGROUND & AIMS: No standardised definition exists for acute, severe AIH (AS-AIH). However, rapid identification of AS-AIH and early corticosteroid therapy may prevent the need for liver transplantation (LT). We set out to determine the clinical outcomes of patients with AS-AIH presenting to our institution with particular focus on the role of corticosteroids. METHODS: Retrospective analysis of a prospectively collated database identified patients presenting with AS-AIH from 1999 to 2009. We defined AS-AIH as an acute presentation with an INR of ⩾1.5 at any time without histological evidence of cirrhosis. RESULTS: 32 patients were identified with AS-AIH. Among the 32 AS-AIH patients 23 were treated with corticosteroids of whom 10 (48%) required LT, whilst all 9 untreated patients required LT (p = 0.01). Untreated patients demonstrated higher MELD scores at presentation (34 vs. 28 p = 0.01) and a non-significant decrease in episodes of sepsis but no difference in sepsis or mortality was observed between untreated or treated patients (11% vs. 26% p = 0.6 and 22% vs. 17% p = 0.99 respectively). Among treated patients, no difference in MELD scores was observed between responders or failures. Despite 59% undergoing LT, six deaths (19%) occurred. CONCLUSION: In a well characterised cohort of patients with AS-AIH, almost 60% required LT and 20% died. There was no difference in prognostic scores between steroid responders and failures and steroid exposure did not appear to jeopardise survival. Patients with AS-AIH should be considered for a trial of corticosteroids expediently whilst a thorough search for sepsis and assessment for LT should occur if clinical deterioration or encephalopathy develops.

ABSTRACT

Latent myeloproliferative disorders (MPDs) can be identified by Janus kinase 2 (JAK2) mutations in patients with idiopathic Budd-Chiari syndrome (BCS). The incidence and clinical outcomes of JAK2 mutations, novel ten-eleven translocation 2 (TET2) mutations, and the 46/1 haplotype in BCS are unknown for liver transplantation (LT). We undertook molecular studies of 66 patients presenting with BCS and correlated the results with the clinical outcomes. An overt MPD was present in 20% of the cases, and a latent MPD confirmed by the presence of a JAK2 mutation was detected in 45%. Testing for a TET2 mutation identified MPDs at the molecular level in another 7% of the subset of patients with BCS who were evaluated. The 46/1 haplotype frequency was significantly greater in BCS patients versus the general population (P < 0.001). The presence of JAK2 and TET2 mutations had no impact on 1-year survival. Thirty-six patients underwent LT, and 12 developed liver-related thrombotic complications (33%). Ten of these 12 patients required retransplantation. Retransplantation was more likely in those patients who developed liver-related thrombotic complications (P < 0.001). A JAK2 mutation was highly associated with the development of thrombotic complications after LT (P = 0.005). In conclusion, the presence of JAK2V617F predicts hepatic and extrahepatic thrombotic complications after LT. Testing for TET2 mutations can identify another 7% of idiopathic BCS patients with molecular MPDs.

ABSTRACT

INTRODUCTION: Optimal management during pregnancy of patients with autoimmune hepatitis (AIH) remains undefined. We therefore reviewed all patients with AIH who reported pregnancy at our centre to identify any pre-conception factors that might predict adverse outcomes. RESULTS: There were 81 pregnancies in 53 women. Median age at conception was 26 years (range 16-42); with 41% of pregnancies occurring in the context of cirrhosis. At conception, 61 patients (75%) were on therapy for AIH. The live birth rate (LBR) was 73% (59/81). Prematurity, occurred in 12/59 (20%) and 6 (11%) required admission to special care baby unit (SCBU). In mothers who were cirrhotic at the time of conception the LBR was lower (p = 0.02) and need for admission to SCBU was higher. The overall maternal complication rate was 31/81 (38%) conceptions. A flare in disease activity occurred in 26/81 (33%) pregnancies. A serious maternal adverse event (death or need for liver transplant) during or within 12-months of delivery, or hepatic decompensation during or within 3-months of delivery, occurred with 9 pregnancies (11%) and was more common in women with cirrhosis (p = 0.028). Maternal therapy had no significant impact on the LBR (p = 0.24), termination rate (p = 0.72), miscarriage rate (p = 0.19) or gestational period (p = 0.8). Flares in AIH were more likely in patients who were not on therapy (p = 0.048) or who had a disease flare in the year prior to conception (p = 0.03). Patients who had a flare in association with pregnancy were more likely to decompensate from a liver standpoint (p = 0.01). CONCLUSIONS: This study demonstrates that poor disease control in the year prior to pregnancy and the absence of drug therapy are associated with poor outcomes whist pregnant. These data should facilitate appropriate pre-conception counselling and appropriate pregnancy management in this cohort.

ABSTRACT

UNLABELLED: Autoimmune hepatitis (AIH) typically responds to treatment in 90% of patients. Early prediction of treatment outcome would be advantageous in clinical practice. We evaluated whether parameters at initiation of therapy or changes in these parameters at day 3 and day 7 following corticosteroid initiation predicted treatment failure. Treatment-naive, jaundiced patients presenting to our tertiary unit between 1999-2009 were identified and mathematical models of prognosis in liver disease scores calculated at day 0, day 3, and day 7. Overall, 72 patients were identified (48 women, 24 men). Treatment failure occurred in 18% (13/72) of patients. At diagnosis, higher median bilirubin (451 µmol/L versus 262 µmol/L, P = 0.02), INR (1.62 versus 1.33, P = 0.005), model for endstage liver (MELD) score (26 versus 20, P = 0.02), MELD-sodium (Na) score (27 versus 22, P = 0.03) and United Kingdom endstage liver disease score (UKELD) score (59 versus 57, P = 0.01) significantly correlated with treatment failure. Analysis of area under the receiver operator characteristic curve (AUROC) values at day 7 identified change (Δ) bilirubin (AUROC 0.68), Δ creatinine (0.69), Δ MELD (0.79), Δ MELD-Na (0.83) and Δ UKELD (0.83) best predicted treatment failure. Specifically, a fall in UKELD of less than 2 points predicted treatment failure with a sensitivity of 85% and specificity of 68%. Of 13 treatment failures, nine required second-line immunosuppression, three required emergency transplant, and one died of sepsis. In total, four patients died in the treatment failure group compared with one in the responder group (4/13 = 31% versus 1/59 = 1.7%, P = 0.003). CONCLUSION: Approximately 20% of icteric AIH presentations fail corticosteroid therapy. This is associated with significant mortality and the need for emergency transplantation. Treatment failure is best predicted by change in MELD-Na and UKELD at day 7. Early identification of nonresponders may allow timely escalation of immunosuppression to prevent clinical deterioration.

ABSTRACT

Severe liver disease in pregnancy is rare. Pregnancy-related liver disease is the most frequent cause of liver dysfunction in pregnancy and provides a real threat to fetal and maternal survival. A rapid diagnosis differentiating between liver disease related and unrelated to pregnancy is required in women who present with liver dysfunction during pregnancy. Research has improved our understanding of the pathogenesis of pregnancy-related liver disease, which has translated into improved maternal and fetal outcomes. Here, we provide an overview of liver diseases that occur in pregnancy, an update on the key mechanisms involved in their pathogenesis, and assessment of available treatment options.

ABSTRACT

BACKGROUND & AIMS: Pregnancy is rare among patients with cirrhosis, and data about complications and outcomes are sparse. We evaluated the utility of prognostic models of severity of cirrhosis in determining outcomes in pregnant women with cirrhosis. METHODS: We evaluated all cirrhotic patients who self-reported pregnancy at our center and correlated prognostic scores at the time of conception with outcomes. RESULTS: Sixty-two pregnancies occurred in 29 women. The median model for end-stage liver disease (MELD) score at conception was 7 (range, 6-17), the median MELD sodium score was 9 (range, 6-17), the median United Kingdom end-stage liver disease (UKELD) score was 44 (range, 36-53), and the median Child-Pugh score was 5 (range, 5-8). The live birth rate was 58%; the median gestational age was 36 weeks. Higher MELD (P = .01), MELD sodium (P = .01), UKELD (P = .01), and Child-Pugh (P = .03) scores were associated with gestation <37 weeks. Maternal complications (ascites, encephalopathy, or variceal hemorrhage) occurred in 10% of patients and were associated with higher MELD (P = .01) and UKELD (P = .02) scores. Receiver operator curve analysis demonstrated that a MELD score ≥10 predicted, with 83% sensitivity and 83% specificity, which patients were likely to have significant, liver-related complications (area under curve, 0.8); a UKELD score ≥47 had 83% sensitivity and 79% specificity (area under curve, 0.8). No patient who had a MELD score ≤6 or a UKELD score ≤42 developed any significant hepatologic complications. CONCLUSIONS: MELD and UKELD scores at the time of conception can be used to predict specific clinical outcomes in pregnant women with cirrhosis.
