ABSTRACT
The night eating syndrome (NES) is characterized by excessive food intake during the evening and night hours, with 25% of the daily intake being consumed post-dinner, paired with ep-isodes of nocturnal food intake, at a frequency of more than twice weekly. The NES has been associated with a misaligned circadian rhythm related to a delay in overall food intake, increased energy and fat consumption. The present cross-sectional study aimed to assess NES in a Greek population and evaluate possible links between NES and chronotype. NES was assessed using the Night Eating Questionnaire (NEQ), and circadian rhythm, sleep and mood were evaluated with the Sleep, Circadian Rhythms, and Mood (SCRAM) questionnaire. A total of 533 adults participated in the study. A relatively high prevalence of NES was revealed, with more than 8.1% (NEQ ≥ 30) of the participants reporting experiencing NES symptoms, depending on the NEQ threshold used. Most participants had the intermediate chronotype. NEQ score was positively associated with the morning chronotype, and SCRAM was negatively related to "Good Sleep". Each point increment in the depression score was associated with 6% higher odds of NES. The early identification of NES gains importance in clinical practice, in a collective effort aiming to reduce NES symptomatology and its detrimental health effects.

Background & Aims: Although worsening liver-related symptoms during pregnancy can occur in primary sclerosing cholangitis (PSC), there are insufficient data to effectively counsel patients on their pre-conception risk and no clear recommendations on monitoring and management during pregnancy. We aimed to describe maternal liver-related symptoms in pregnancy, both before and after PSC diagnosis, and explore factors associated with worsening symptoms and liver-related outcomes. Methods: We conducted a multicentre retrospective observational study of females with PSC and known pregnancy with live birth, via the International PSC Study Group. We included 450 patients from 12 European centres. Data included clinical variables, liver-related symptoms (pruritus and/or cholangitis) during pregnancy, and liver biochemistry. A composite primary endpoint of transplant-free survival from time of PSC diagnosis was used. Results: There were 266 pregnancies in 178 patients following PSC diagnosis. Worsening liver-related symptoms were reported in 66/228 (28.9%) pregnancies; they had a reduced transplant-free survival (p = 0.03), which retained significance on multivariate analysis (hazard ratio 3.02, 95% CI 1.24-7.35; p = 0.02).Abnormal biochemistry and/or liver-related symptoms (pruritus and/or cholangitis) were noted during pregnancy before PSC diagnosis in 21/167 (12.6%) patients. They had a reduced transplant-free survival from pregnancy (p = 0.01), which did not retain significance in a multivariable model (hazard ratio 1.10, 95% CI 0.43-2.85; p = 0.84). Conclusions: Liver-related symptoms are frequently encountered during pregnancies before the diagnosis of PSC, and pregnancy may expose the pre-clinical phase of PSC in some patients. Worsening liver-related symptoms were seen in a third of our cohort with known PSC during pregnancy; and this subgroup had a poorer prognosis, which may be related to more advanced liver disease at time of pregnancy and/or a more severe disease phenotype. Impact and implications: Patients with PSC can develop worsening of their liver-related symptoms during pregnancy; however, risk factors for this and the long-term implications are not known. We identified that there is a significant risk of these symptoms in pregnancy, both before and after PSC has been diagnosed, particularly in patients with elevated alkaline phosphatase. Furthermore, our findings suggest that worsening symptoms during pregnancy may be associated with adverse long-term clinical outcomes of liver transplantation and death in patients with known PSC. This may be related to the presence of more advanced liver disease at time of pregnancy. This information can be used to counsel patients with PSC before conception and identify patients who need close follow-up after delivery.
ABSTRACT
Background: FibroMeter and FibroMeter vibration-controlled transient elastography (FibroMeter VCTE) were assessed in a Greek cohort of patients with chronic viral hepatitis (CVH) B and C or metabolic dysfunction-associated steatotic liver disease (MASLD) to evaluate their accuracy in predicting advanced liver fibrosis against other well-validated noninvasive markers. Methods: Group 1: n=83 CVH and group 2: n=38 MASLD patients underwent liver biopsy and transient elastography (TE) on the same day as sera collection. FibroMeter scores APRI and FIB-4 were calculated in all 121 patients, while MASLD fibrosis score (MFS) was also calculated in group 2. Results: In CVH, FibroMeter VCTE performed equivalently to TE and better than the other markers in predicting advanced (≥F3) and significant (≥F2) fibrosis (area under the receiver operating characteristic curve [AUC] 0.887, P<0.001 for F3; AUC 0.766 P<0.001 for F2). FibroMeter Virus (cutoff 0.61) had lower sensitivity (20%) but performed equivalently to APRI and FIB-4. In MASLD, all markers but APRI performed equivalently in predicting advanced fibrosis. FibroMeter VCTE >0.2154 had the same sensitivity (100%) and specificity (81%) as TE (cutoff >7.1 kPa). FibroMeter MASLD >0.25 performed equivalently to MFS and FIB4, but with higher specificity (100%). Both FibroMeter and FibroMeter VCTE correlated with liver histology but not with liver enzymes. Conclusions: FibroMeter VCTE predicts accurately advanced fibrosis in CVH and MASLD, irrespectively of transaminase levels. FibroMeter Virus can be applied only as an alternative marker in CVH, while FibroMeter MASLD performs equally to TE and calculated scores (MFS, FIB-4) in predicting advanced fibrosis in MASLD patients.
ABSTRACT
Background: Primary biliary cholangitis (PBC) has been long associated with impairment of various aspects of health-related quality of life (HRQoL) with substantial differences among populations. This study evaluated for the first-time the HRQoL in Greek PBC patients in conjunction with clinical and laboratory parameters of patients. Methods: We analyzed prospectively collected data regarding the HRQoL by using the PBC-40 and SF-36 questionnaires in 374 Greek PBC patients and 131 age- and sex-matched non-PBC controls. Results: The PBC-40 questionnaire is a reliable tool for HRQoL assessment in Greek PBC patients (Cronbach's α > 0.7 for all domains). Implementation of PBC-40 and SF-36 demonstrated significant impairment of HRQoL in Greek PBC patients compared to controls (P < 0.001 for all comparisons). Emotional dysfunction, social impairment, and fatigue (100%, 80.5% and 78%, respectively) were amongst those with the highest, while cognitive dysfunction (32%) with the least impact on quality of life. Fatigue was associated with female sex (P = 0.02), longer disease duration (P = 0.01), presence of cirrhosis (P = 0.02) and positivity for PBC-specific ANA (P < 0.05), while social dysfunction with increased age (P < 0.001), longer disease duration (P < 0.001) and presence of cirrhosis (P = 0.004). Living in urban areas was linked to impaired social function (P = 0.04), cognition (P = 0.02), fatigue (P = 0.04) and increased total PBC-40 score (P = 0.01). Conclusions: Implementation of PBC-40 and SF-36 revealed impaired HRQoL in Greek PBC patients with fatigue, social and emotional dysfunction exerting the highest impact. However, total, and individual PBC-40 scores were lower than that reported in studies from Northern/Central Europe and Canada. Deranged HRQoL was associated with severity of liver disease and presence of PBC-specific ANA.
ABSTRACT
BACKGROUND & AIMS: Antimitochondrial antibodies (AMA) are specific markers for the diagnosis of primary biliary cholangitis (PBC) but can also be found occasionally in patients with autoimmune hepatitis (AIH). The present large multicentre cohort study assessed the prevalence and significance of AMA in AIH-patients. METHODS: 123 AMA-positive AIH-patients were investigated and compared with 711 age-matched AMA-negative AIH-patients and 69 patients with AIH/PBC variant. RESULTS: AMA prevalence in AIH-patients was 5.1% (range: 1.2%-11.8%). AMA-positivity was associated with female sex (p = 0.031) in AMA-positive AIH-patients but not with liver biochemistry, bile duct injury on liver biopsy, disease severity at baseline and response to treatment compared to AMA-negative AIH-patients. Comparing AMA-positive AIH-patients to those with AIH/PBC variant, there was no difference in disease severity. Regarding liver histology, AIH/PBC variant patients were characterized by the presence of at least one feature of bile duct damage (p<0.001). Response to immunosuppressive treatment was similar among groups. From AMA-positive AIH patients only those with evidence of non-specific bile duct injury had higher risk to progress to cirrhosis (HR=4.314, 95%CI: 2.348-7.928; p<0.001). During follow-up, AMA-positive AIH-patients had higher risk to develop histological bile duct injury (HR 4.654, 95%CI 1.829-11.840; p = 0.001). CONCLUSIONS: AMA presence is relatively common among AIH-patients, but their clinical significance seems important only when they co-exist with non-specific bile duct injury at the histological level. Therefore, a careful evaluation of liver biopsy seems of utmost importance in these patients.

Primary biliary cholangitis (PBC) is a chronic cholestatic liver disease characterized by immune-driven destruction of small intrahepatic bile ducts leading a proportion of patients to hepatic failure over the years. Diagnosis at early stages in concert with ursodeoxycholic acid treatment has been linked with prevention of disease progression in the majority of cases. Diagnosis of PBC in a patient with cholestasis relies on the detection of disease-specific autoantibodies, including anti-mitochondrial antibodies, and disease-specific anti-nuclear antibodies targeting sp100 and gp210. These autoantibodies assist the diagnosis of the disease, and are amongst few autoantibodies the presence of which is included in the diagnostic criteria of the disease. They have also become important tools evaluating disease prognosis. Herein, we summarize existing data on detection of PBC-related autoantibodies and their clinical significance. Moreover, we provide insight on novel autoantibodies and their possible prognostic role in PBC patients.

Autoimmune rheumatic diseases (AIRDs) constitute a set of connective tissue disorders and dysfunctions with akin clinical manifestations and autoantibody responses. AIRD treatment is based on a comprehensive approach, with the primary aim being achieving and attaining disease remission, through the control of inflammation. AIRD therapies have a low target specificity, and this usually propels metabolic disturbances, dyslipidemias and increased cardiovascular risk. Ceramides are implicated in inflammation through several different pathways, many of which sometimes intersect. They serve as signaling molecules for apoptosis, altering immune response and driving endothelial dysfunction and as regulators in the production of other molecules, including sphingosine 1-phosphate (S1P) and ceramide 1-phosphate (C1P). With lipid metabolism being severely altered in AIRD pathology, several studies show that the concentration and variety of ceramides in human tissues is altered in patients with rheumatic diseases compared to controls. As a result, many in vitro and some in vivo (animal) studies research the potential use of ceramides as therapeutic targets in rheumatoid arthritis (RA), ankylosing spondylitis, systemic lupus erythematosus, fibromyalgia syndrome, primary Sjögren's syndrome, systemic sclerosis, myositis, systemic vasculitis and psoriatic arthritis. Furthermore, the majority of ceramide synthesis is diet-centric and, as a result, dietary interventions may alter ceramide concentrations in the blood and affect health. Subsequently, more recently several clinical trials evaluated the possibility of distinct dietary patterns and nutrients to act as anti-ceramide regimes in humans. With nutrition being an important component of AIRD-related complications, the present review details the evidence regarding ceramide levels in patients with AIRDs, the results of anti-ceramide treatments and discusses the possibility of using medical nutritional therapy as a complementary anti-ceramide treatment in rheumatic disease.

BACKGROUND & AIMS: Evidence for the benefit of scheduled imaging for early detection of hepatobiliary malignancies in primary sclerosing cholangitis (PSC) is limited. We aimed to compare different follow-up strategies in PSC with the hypothesis that regular imaging improves survival. METHODS: We collected retrospective data from 2975 PSC patients from 27 centres. Patients were followed from the start of scheduled imaging or in case of clinical follow-up from 1 January 2000, until death or last clinical follow-up alive. The primary endpoint was all-cause mortality. RESULTS: A broad variety of different follow-up strategies were reported. All except one centre used regular imaging, ultrasound (US) and/or magnetic resonance imaging (MRI). Two centres used scheduled endoscopic retrograde cholangiopancreatography (ERCP) in addition to imaging for surveillance purposes. The overall HR (CI95%) for death, adjusted for sex, age and start year of follow-up, was 0.61 (0.47-0.80) for scheduled imaging with and without ERCP; 0.64 (0.48-0.86) for US/MRI and 0.53 (0.37-0.75) for follow-up strategies including scheduled ERCP. The lower risk of death remained for scheduled imaging with and without ERCP after adjustment for cholangiocarcinoma (CCA) or high-grade dysplasia as a time-dependent covariate, HR 0.57 (0.44-0.75). Hepatobiliary malignancy was diagnosed in 175 (5.9%) of the patients at 7.9 years of follow-up. Asymptomatic patients (25%) with CCA had better survival if scheduled imaging had been performed. CONCLUSIONS: Follow-up strategies vary considerably across centres. Scheduled imaging was associated with improved survival. Multiple factors may contribute to this result including early tumour detection and increased endoscopic treatment of asymptomatic benign biliary strictures.

Background & Aims: We have shown previously that mycophenolate mofetil (MMF) might be used as first-line treatment instead of azathioprine (AZA) in individuals with autoimmune hepatitis (AIH). Herein, we present our long-term prospective data on response and outcome after first-line therapy with MMF in treatment-naïve individuals with AIH, as similar data are missing. Methods: During the 21 years of the study, 292 individuals with AIH were included (females: 213; median age: 59 [17-85] years). Patients received either prednisolone 0.5-1 mg/kg/day alone (n = 19) or in combination with AZA 1-2 mg/kg/day (n = 64) or MMF (n = 183). The tapering schedule of prednisolone was identical between groups. We assessed the rates of complete biochemical response (CBR) at 6 months, 12 months, and the end of follow-up; non-response (4 weeks of treatment); CBR off prednisolone; adverse effects; CBR off treatment; histological remission; and overall and liver-related mortality between the AZA and MMF groups. Results: The MMF group had lower non-response (p = 0.02) and higher CBR rates at 12 months (86 vs. 71.8%; p <0.05) and the end of follow-up (96 vs. 87.2%; p = 0.03) than the AZA group. Treatment change was more frequent in the AZA group (43.7 vs. 11%; p <0.001), mostly because of intolerance, whereas MMF was proven safe (serious complications 3.8 vs. 18.8%; p = 0.0003). MMF-treated patients were more frequently eligible to stop immunosuppression according to the guidelines (p <0.05). Cirrhosis at diagnosis, age at diagnosis >60 years, and longer disease duration were independent predictors of liver-related mortality. Conclusions: MMF seems an efficient alternative first-line treatment option for AIH, bearing lower non-response at 4 weeks and higher CBR rates at 12 months and the end of follow-up than AZA. In addition, MMF was proven to be safe, leading more frequently to the eligibility for stopping immunosuppression according to the guidelines. Impact and implications: For more than 40 years, azathioprine (AZA) has been considered the standard treatment for induction and maintenance of response in autoimmune hepatitis (AIH). However, treatment usually needs to be maintained for life, as relapses are common after AZA cessation. Therefore, alternative treatment options are needed. Herein, we showed that the use of mycophenolate mofetil (MMF) as an alternative first-line immunosuppressant was much more efficient in the long-term than AZA as attested by the lower non-response rates at 4 weeks and higher response rates at 12 months and the end of follow-up. Moreover, AZA-treated patients were more prone to change treatment because of intolerance, whereas MMF-treated patients were more often eligible to achieve treatment withdrawal.
ABSTRACT
Theoretical evidence and previous studies suggest that oralnutrient supplementation (ONS) with n-3 fatty acids for rheumatoid arthritis (RA) has the potential to lower disease activity indicators and non-steroidal anti-inflammatory drug (NSAID) uptake. A systematic search was conducted on five databases/registries from inception until May 23, 2021 with the aim to identify randomized placebo-controlled trials comparing n-3 supplements to placebo on disease-specific outcomes. A total of 23 studies matched the criteria (PROSPERO: CRD42019137041). Pooled analyses revealed that n-3 ONS provided a small effect in reducing pain [standardized mean difference (SMD): -0.16, 95% confidence intervals (CI): -0.40 to 0.09], and tender (SMD: -0.20, 95% CI: -0.46 to 0.05) and swollen joint count (SMD: -0.10, 95% CI: -0.28 to 0.07). In sensitivity analyses, there was a small effect in the reduction of NSAIDs intake (SMD: -0.22, 95% CI: -0.90 to 0.46), and c-reactive protein was reduced only by 0.21 mg/dL (95% CI: -0.75 to 0.33). Similar findings were observed regarding other objective/subjective outcomes. The certainty of the evidence was mostly of "very low/low" quality. Overall, n-3 ONS in RA might have a limited clinical benefit. Previous findings suggesting a reduction in NSAID intake may have been biased from the inadequate blinding of interventions.
ABSTRACT
HBV RNA is considered as a promising predictor in patients who discontinue nucleos(t)ide analogues (NAs). We determined HBV RNA levels in non-cirrhotic HBeAg-negative patients who discontinued NAs and assessed their predictability for 12-month outcomes. Fifty-seven patients of DARING-B study were included. HBV RNA levels were determined in stored monthly serum samples drawn at 0-3 months after end of therapy (EOT). Other markers previously determined in the same cohort including hepatitis B core-related antigen (HBcrAg) were also assessed. HBV RNA at EOT was detectable in 7% of patients, who developed virological/clinical relapse and required retreatment at month 2; in patients with undetectable EOT HBV RNA, 12-month cumulative rates of virological relapse, clinical relapse and retreatment were 68%, 28% and 21%, respectively (p ≤ 0.008). HBV RNA at month-1 after EOT was detectable in 19% of patients being associated with higher probability only of virological relapse (p = 0.001). HBV RNA levels correlated significantly to HBV DNA, HBcrAg, ALT and interferon-induced protein-10, but not HBsAg levels. Combined EOT HBV RNA and HBcrAg detection and/or HBsAg >1000 IU/ml was associated only with higher probability of retreatment having higher sensitivity and lower specificity than HBV RNA alone. In conclusion, serum HBV RNA is detectable in a minority of non-cirrhotic HBeAg-negative patients under effective long-term NAs therapy offering low sensitivity but 100% specificity for early retreatment due to severe clinical relapses after NA discontinuation. The combinations of EOT HBV RNA with HBcrAg and/or high HBsAg levels increase sensitivity but decrease specificity for prediction of retreatment after NAs withdrawal.

BACKGROUND: Spontaneous bacterial peritonitis (SBP) is an ominous complication of decompensated cirrhosis. This study aimed to assess several epidemiological, clinical, microbiological and outcome characteristics in Greek patients with SBP, as no solid representative nationwide data of this type was available. METHODS: During a 3-year period, 77 consecutive patients with SBP (61 male; median age: 67 years; model for end-stage liver disease [MELD] score: 20), diagnosed and followed in 5 tertiary liver units, were prospectively recruited and studied. Various prognostic factors for disease outcome were studied. RESULTS: Thirty-eight patients had alcohol-related cirrhosis, 17 viral hepatitis, 6 non-alcoholic steatohepatitis, 6 autoimmune liver diseases, and 10 cryptogenic cirrhosis. Hepatocellular carcinoma (HCC) was present in 23 (29.9%), whereas 10 (13%) had portal vein thrombosis. The first SBP episode at baseline was community-acquired in 53 (68.8%), while in 24 (31.1%) was hospital-acquired, with predominant symptoms abdominal pain and encephalopathy. A positive ascitic culture was documented in 36% of patients in the initial episode, with almost equal gram (+) and gram (-) pathogens, including 3 multidrug-resistant pathogens. Significant factors for 6-month survival were: higher MELD score, previous b-blocker use, lower serum albumin, higher lactate on admission and need for vasopressors, while factors for 12-month survival were MELD score and lactate. For overall survival, higher MELD score and lactate along with HCC presence were negative predictive factors. CONCLUSIONS: MELD score, lactate, albumin, HCC and treatment with vasopressors were predictive of survival in SBP patients. In hospital-acquired SBP the prevalence of difficult-to-treat pathogens was higher.
ABSTRACT
BACKGROUND: The epidemiology of hepatitis B virus (HBV) infection has changed in recent years as a result of various factors. Our aim was to assess the epidemiological characteristics and the evolution of the HBV infection in a well-defined area of Greece. METHOD: Prospectively collected data from 1910 consecutive patients (60.8% male, age: 50.1 years) with chronic hepatitis B (CHB) followed from 1999-2016 were analyzed. RESULTS: Of the patients evaluated, 90.6% were of Greek and 8% of Albanian origin. Vertical/intrafamilial transmission during early childhood (56.8%) and traditional practices (17.2%) were the most common infection sources. Several areas with higher rates of CHB were identified. At first evaluation, 68.8% had chronic infection, 21.7% chronic hepatitis, 6.1% cirrhosis and 3.4% hepatocellular carcinoma (HCC). Comparison between 2 periods (1999-2010 and 2011-2016) revealed older age and longer disease duration at first presentation (P<0.001 for both) to be more common during 2011-2016, while patients of foreign nationality doubled during this period. There was a trend towards more advanced disease stage at first assessment during 2011-2016. Patients after 2011 had lower rates of virological and biochemical breakthrough (P<0.001 for both) during treatment with new antivirals. In addition, fewer patients progressed to cirrhosis (P=0.02) and HCC (P=0.04). CONCLUSIONS: CHB continues to be a major health problem in Central Greece, as highlighted by the preservation of high prevalence areas and a tendency towards an increase of chronic liver disease burden longitudinally. Our data highlight the need for scaling-up prevention and treatment strategies, especially in at-risk populations.
ABSTRACT
Hepatocellular carcinoma (HCC), the commonest among liver cancers, is one of the leading causes of mortality among malignancies worldwide. Several reports demonstrate autoimmune liver diseases (AILDs), including autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC) to confer increased risk of hepatobiliary malignancies, albeit at lower frequencies compared to other liver diseases. Several parameters have been recognized as risk factors for HCC development in AIH and PBC, including demographics such as older age and male sex, clinical features, the most decisive being cirrhosis and other co-existing factors, such as alcohol consumption. Moreover, biochemical activity and treatment response have been increasingly recognized as prognostic factors for HCC development in AIH and PBC. As available treatment modalities are effective only when HCC diagnosis is established early, surveillance has been proven essential for HCC prognosis. Considering that the risk for HCC is not uniform between and within disease groups, refinement of screening strategies according to prevailing demographic, clinical, and molecular risk factors is mandated in AILDs patients, as personalized HCC risk prediction will offer significant advantage in patients at high and/or medium risk. Furthermore, future investigations should draw attention to whether modification of immunosuppression could benefit AIH patients after HCC diagnosis.
ABSTRACT
AIMS: Differential diagnosis of autoimmune hepatitis (AIH) incorporates various liver diseases, including alcoholic liver disease (ALD). We report on clinical, laboratory and outcome characteristics of AIH patients who were initially referred as ALD based on increased alcohol consumption (AIH/ALD). METHODS: From 2000-2019, we retrospectively identified 12 AIH/ALD patients [9 males, age: 61 (30-73) years] in our prospective data base of 317 AIH patients. RESULTS: AIH diagnosis was based on aminotransferases elevation in 10 patients, high IgG in 8, compatible autoantibody profile in all and typical/compatible histology in all 9 with available biopsy. There were no significant differences of baseline demographics, presentation, cirrhosis at diagnosis, response to treatment and simplified score compared to 45 age- and sex-matched AIH patients without alcohol consumption and 44 age- and sex-matched ALD patients. However, the AIH/ALD cohort was characterized by more frequent progression to cirrhosis, higher liver-related deaths and overall mortality compared to AIH, though similar to the ALD group. AST/ALT ratio>1 seems to bear a good positive (0.84) and negative predictive value (0.88) for ALD and AIH diagnosis, respectively, but cannot help in discriminating the AIH/ALD variant. CONCLUSIONS: AIH should not be forgotten in patients with alcohol use when clinical and laboratory features hint towards the diagnosis of AIH/ALD variant as this group seems to have worse outcome compared to those with AIH alone suggesting the need for closer follow-up and surveillance. Reliable autoantibody testing and cautious interpretation of liver histology appear mandatory for AIH diagnosis in these difficult to diagnose cases.

Background/Aims: As previous real-world studies and meta-analyses have shown that mycophenolate mofetil (MMF) might have better efficacy than azathioprine (AZA) in autoimmune hepatitis (AIH), we conducted a propensity matching study to assess the efficacy and safety of MMF vs. AZA. Methods: All 126 consecutive treatment-naive adult AIH patients, diagnosed and followed in our department since 2016, were included. Patients received prednisolone 0.5-1 mg/kg/day plus either AZA 1-2 mg/kg/day or 1.5-2 g/day MMF. The tapering of prednisolone was identical between groups. Results: After propensity matching score and adjustment for known factors affecting response to treatment and outcome, 64 patients were included in the study (MMF = 32 and AZA = 32). Rates of non-response, complete biochemical response (CBR) at 6 and 12 months, and prednisolone withdrawal (6 months, 12 months, and end of follow-up) were identical between groups. However, MMF treatment was significantly associated with CBR at the end of follow-up [odds ratio (OR) 11.259; 95% CI: 1.3-97.4, p = 0.028]. AZA patients were more prone to stop treatment due to AZA intolerance/insufficient response (p = 0.0001). At the end of follow-up, the overall efficacy of each schedule was also significantly higher in the MMF group compared to the AZA group (p = 0.0001). Conclusion: We showed for the first time in a propensity matching study that MMF can be used as first-line therapy in AIH as attested by the significantly higher CBR at end of follow-up compared to AZA. Whether this better efficacy is also associated with higher histological remission rates and sustained CBR off immunosuppression needs further evaluation.

Hepatic brucelloma (HB), a rare manifestation of brucellosis, refers to liver involvement in the form of abscess. A 35-year-old woman stockbreeder was admitted due to 1-month history of evening fever, sweating and weight loss, while she was on 3-week course of rifampicin/doxycycline for suspected brucellosis. On admission, she had hepatosplenomegaly and a systolic murmur, while cholestasis, increased inflammation markers and a strong-positive Wright-Coombs test were the main laboratory findings. As blood and bone marrow cultures were unrevealing, further investigation with CT imaging showed a central liver calcification surrounded by heterogeneous hypodense area being compatible with HB. Material from CT-guided drainage tested negative for Brucella spp. After failure to improve on a 10-week triple regiment, surgical excision was decided and Brucella spp were identified by PCR. Our case highlights challenges in establishing HB diagnosis, which should be considered on the right epidemiological context and when serological and radiological evidence favour its diagnosis.

BACKGROUND: Non-invasive criteria are needed for Crohn's disease (CD) diagnosis, with several biomarkers being tested. Results of individual diagnostic test accuracy studies assessing the diagnostic value of pancreatic autoantibodies-to-glycoprotein-2 (anti-GP2) tests for the diagnosis of CD appear promising. AIM: To systematically review and meta-analyze evidence on the diagnostic accuracy of anti-GP2 tests in patients with suspected/confirmed CD. METHODS: An electronic search was conducted on PubMed, Cochrane-CENTRAL and grey literature (CRD42019125947). The structured research question in PICPTR format was "Population" including patients with symptoms akin to CD, the "Index test" being anti-GP2 testing, the "Comparator" involved standard CD diagnosis, the "Purpose of test" being diagnostic, "Target disorder" was CD, and the "Reference standard" included standard clinical, radiological, endoscopical, and histological CD diagnostic criteria. Quality was assessed with the Quality Assessment of Diagnostic Accuracy Studies-2 tool and hierarchical models were employed to synthesize the data. RESULTS: Out of 722 studies retrieved, 15 were meta-analyzed. Thirteen studies had industry-related conflicts-of-interest, and most included healthy donors as controls (spectrum bias). For the combination of IgA and/or IgG anti-GP2 test, the summary sensitivity was 20% (95% confidence interval: 10%-29%) at a median specificity of 97%. If the test was applied in 10000 suspected patients, 9669 would be true negatives and in 26, the diagnosis would be missed. In this hypothetical cohort, the anti-GP2 would fail to produce a diagnosis for 81.3% of the positive cases. Low summary points of sensitivity and high specificity were estimated for the IgG or IgA anti-GP2 test. Analogous results were observed when the analyses were restricted using specific cut-offs, or when ulcerative colitis patients were used as comparators. CONCLUSION: Anti-GP2 tests demonstrate low sensitivity and high specificity. These results indicate that caution is required before relying on its diagnostic value. Additionally, the need for improving the methodology of diagnostic test accuracy studies is evident.

Reliable predictors of outcomes after treatment discontinuation in HBeAg-negative chronic hepatitis B (CHB) patients have not been established. We investigated the role of hepatitis B surface antigen (HBsAg), interferon-inducible protein-10 (IP10) and hepatitis B core-related antigen (HBcrAg) serum levels as predictors of HBsAg loss, relapse and retreatment in noncirrhotic HBeAg-negative CHB patients who discontinued long-term antiviral therapy. All HBsAg-positive (n = 57) patients of the prospective DARING-B study were included and followed monthly for 3 months, every 2/3 months until month-12 and every 3/6 months thereafter. HBsAg, IP10 and HBcrAg levels were measured by enzyme immunoassays, and SCALE-B score was calculated. Twelve patients achieved HBsAg loss before retreatment with 18-month cumulative incidence of 25%. Independent predictors of HBsAg loss were baseline HBsAg and month-1 IP10 levels. Of 10 patients with baseline HBsAg ≤100 IU/mL, 70% cleared HBsAg and 10% required retreatment. Of 23 patients with baseline HBsAg >1000 IU/mL, 4% cleared HBsAg and 43% required retreatment. Of 24 patients with intermediate baseline HBsAg (100-1000 IU/mL), 17% cleared HBsAg and 21% required retreatment; in this subgroup, month-1 IP10 was significantly associated with HBsAg loss, which occurred in 30% and 7% of cases with IP10 >150 and ≤150 pg/mL, respectively. Baseline HBcrAg was undetectable in all patients who cleared HBsAg and was associated with retreatment. SCALE-B was associated with HBsAg loss but not with relapse or retreatment. In conclusion, HBsAg, IP10 and HBcrAg serum levels can be useful for the decisions and management of treatment discontinuation in noncirrhotic Caucasian patients with HBeAg-negative CHB.
