Sub-optimal therapy of patients with primary biliary cholangitis (PBC) in the real-life stetting of the German PBC cohort.

Real-world data on the management of patients with primary biliary cholangitis (PBC) are so far scarce in Germany. Therefore, we aimed to establish a nationwide registry and describe the clinical characteristics and therapy of PBC patients.Three different cohorts defined as ursodeoxycholic acid (UDCA) responders, as inadequate responders according to Paris II criteria, and as newly diagnosed patients were prospectively recruited.This manuscript includes the baseline data of the project.In total, 33/77 (43%) contacted centres (58% of university hospitals, 38% of non-university hospitals, and 24% of private practices) recruited 515 patients including 204 UDCA responders, 221 inadequate responders to UDCA, and 90 newly diagnosed patients.All patients were treated with UDCA; however, a UDCA dosage below the recommended dosage of 13 mg/kg/d was observed in 38.5% of individuals after 12 months of treatment. UDCA dosages were lower in nonacademic compared to academic centres.Only 75/219 (38.5%) of inadequate responders to UDCA received a second-line therapy with obeticholic acid (OCA) and/or bezafibrate (BZF). OCA (13% vs. 4.5%) and BZF (14% vs. 6.5%) were significantly more often prescribed by academic vs. nonacademic centres.Pruritus (27% vs. 15.5%), fatigue (23% vs. 4.5%), and sicca syndrome (14% vs. 1%) were significantly more often reported by academic centres.The German PBC registry could be established, which indicates suboptimal therapy in a relevant proportion of patients and shows significant differences between academic and nonacademic centres. Results are fundamental to improving clinical management at different levels of care.

Only partial improvement in health-related quality of life after treatment of chronic hepatitis C virus infection with direct acting antivirals in a real-world setting-results from the German Hepatitis C-Registry (DHC-R).

Improvement of health-related quality of life (HRQoL) is frequently reported as a benefit when treating hepatitis C virus infection (HCV) with direct acting antivirals (DAA). As most of the available data were obtained from clinical trials, limited generalizability to the real-world population might exist. This study aimed to investigate the impact of DAA therapy on changes in HRQoL in a real-world setting. HRQoL of 1180 participants of the German Hepatitis C-Registry was assessed by Short-Form 36 (SF-36) questionnaires. Scores at post-treatment weeks 12-24 (FU12/24) were compared to baseline (BL). Changes of ≥2.5 in mental and physical component summary scores (MCS and PCS) were defined as a minimal clinical important difference (MCID). Potential predictors of HRQoL changes were analysed. Overall, a statistically significant increase in HRQoL after DAA therapy was observed, that was robust among various subgroups. However, roughly half of all patients failed to achieve a clinically important improvement in MCS and PCS. Low MCS (p < .001, OR = 0.925) and PCS (p < .001, OR = 0.899) BL levels were identified as predictors for achieving a clinically important improvement. In contrast, presence of fatigue (p = .023, OR = 1.518), increased GPT levels (p = .005, OR = 0.626) and RBV containing therapy regimens (p = .001, OR = 1.692) were associated with a clinically important decline in HRQoL after DAA therapy. In conclusion, DAA treatment is associated with an overall increase of HRQoL in HCV-infected patients. Nevertheless, roughly half of the patients fail to achieve a clinically important improvement. Especially patients with a low HRQoL seem to benefit most from the modern therapeutic options.

Treatment-failure to direct antiviral HCV regimens in real world: frequency, patient characteristics and rescue therapy - data from the German hepatitis C registry (DHC-R).

BACKGROUND: Virologic failure to approved combinations of direct antiviral agents (DAA) in patients with chronic hepatitis C virus (HCV) infection is rare. Mostly it involves difficult to treat patients with advanced liver disease and prior interferon-experience. Before approval of VOX/VEL/SOF, a restricted number of patients received rescue treatment, and the choice of DAA combinations for re-treatment were selected on an individual basis. In the present analysis, patient characteristics and rescue-regimens after virologic failure mainly based on first generation DAAs are described. PATIENTS AND METHODS: Data were obtained from the German Hepatitis C-Registry (DHC-R), which is a national multicenter real-world cohort currently including about 16 500 patients recruited by more than 250 centers. The present analysis is based on 6683 patients who initiated a DAA therapy and for whom follow-up data (per-protocol analysis) were available. RESULTS: Among the patients, 188 (2.8 %) experienced a virologic relapse. Compared to SVR-patients, relapse patients were significantly more often male (77.7 % versus 56.9 %, respectively, p < 0.001), showed cirrhosis significantly more (48.4 % versus 28.1 %, respectively, p < 0.001) and a prior interferon-containing therapy (46.3 % versus 39.0 %, respectively, p = 0.049). The majority of patients who relapsed were infected with genotype 1 (47.4 %) followed by genotype 3 (29.8 %), and 95 relapse patients started DAA re-treatment. Characteristics of patients with rescue-treatment are similar to these of patients with relapse after initial DAA treatment. Thirty-one of 39 patients with complete follow-up data achieved SVR (79.5 %), and 8 patients had a relapse again (20.5 %). Patients who received rescue treatment including a new DAA class according to guidelines, except patients who received VOX/VEL/SOF, showed higher SVR rates than the entire group (21/25, 84 %). All patients who received VOX/VEL/SOF achieved SVR (n = 4, 100 %). CONCLUSIONS: Patients with failure with DAA combination therapies are a difficult but urgent to treat population with the frequent presence of cirrhosis and prior treatment failure with interferon-based therapies. Rescue therapy with inclusion of a new DAA class leads to high SVR rates, but multiple targeted therapy with VOX/VEL/SOF seems to be most effective.

Estimation of liver fibrosis by noncommercial serum markers in comparison with transient elastography in patients with chronic hepatitis C virus infection receiving direct-acting antiviral treatment.

Treatment decisions are based on extent of fibrosis in patients with chronic hepatitis C (HCV) infection. Noninvasive diagnostic tools may help to avoid liver biopsy. We investigated the diagnostic accuracy of noncommercial serum scores in comparison with transient elastography (TE). Data analysis was undertaken based on 2458 patients enrolled in the German Hepatitis C Registry, in a prospective, observational study. Aspartate aminotransferase-to-platelet ratio index (APRI), FORNS index and FIB-4 score were calculated and the diagnostic accuracy was compared to TE. As estimated by TE, 955 (38.9%) patients had absence of significant fibrosis (SF), 736 (29.9%) patients had SF, and 767 (31.2%) patients were shown to have cirrhosis. Patients with absence of SF had a sustained virological response (SVR) rate of 97.9%, whereas SVR was attained in 96.2% and 92.2% in those with SF and cirrhosis, respectively (P < 0.0001). The area under the receiver operator characteristic curve (AUROC), sensitivity and specificity in discriminating of SF were 0.789, 0.596 and 0.939 by APRI; 0.838, 0.852 and 0.748 by FORNS index; and 0.828, 0.658 and 0.946 by FIB-4 score. AUROCs for the prediction of cirrhosis, sensitivity and specificity were 0.881, 0.851 and 0.854 by APRI; 0.846, 0.948 and 0.628 by FORNS index; and 0.907, 0.907 and 0.848 by FIB-4 score. In conclusion, in the present multicentre real-world cohort, SF and cirrhosis were predicted with high accuracy with noncommercial serum markers using TE as reference. Further prospective long-term follow-up is necessary to compare biomarkers with TE concerning liver-related outcome and overall mortality.

[4 years of direct-acting antivirals (DAAs) in the German Hepatitis C-Registry (DHC-R)]. / Deutsches Hepatitis C-Register (DHC-R) ­ eine Zwischenbilanz 4 Jahre nach Zulassung direkt antiviraler Substanzen (DAAs).

BACKGROUND: More than 250 000 patients suffer from chronic hepatitis C in Germany. Several potent, direct-acting antiviral drugs have been approved since 2014. The aim of the German Hepatitis C-Registry (DHC-R) is to describe the epidemiology and patient care of hepatitis C and to investigate the efficacy and safety of new treatment options in real-world settings. METHODS: The DHC-R is a prospective multicenter non-interventional registry study that includes 327 centers throughout Germany. All approved treatment options have been documented. The current analysis differentiated 4 phases: 2/2014 - 12/2014, 1/2015 - 12/2015, 1/2016 - 7/2017 and 8/2017 - 7/2018. FINDINGS: Between February 2014 and July 2018, 12 170 patients were included in the registry (61.3 % male), and antiviral treatment was initiated in 11 268. The mean age declined from 52.3 years (phase 1) to 49.3 years (phase 4), while the proportion of patients with previous or ongoing drug abuse increased (26.3 % to 43.1 %). In 2014, 35.1 % of treated patients had liver cirrhosis, which declined to 16.5 % in phase 4. The HCV genotype distribution showed marked fluctuations, with most recent increases in HCV genotype 3 (30 % in phase 4). Per-protocol sustained virological response rates increased from 92.8 % in 2014 to 94.4 % in 2017/18 with excellent tolerability. SUMMARY: The DHC-R mirrors patient care of chronic hepatitis in the real-world setting in Germany and provides insights into epidemiology developments. It also confirms the high efficacy and safety of novel treatment options.

Lethal thrombosis of the iliac artery caused by Aspergillus fumigatus after liver transplantation: case report and review of the literature.

BACKGROUND: Aspergillus fumigatus infections frequently occur after solid organ transplantation. Yet, a fungal thrombosis after liver transplantation is an exceptional finding. CASE PRESENTATION: We report on a 44-year-old female with an aspergillosis after liver transplantation for autoimmune hepatitis. On postoperative day (pod) 7, seizures occurred and imaging diagnostics revealed an intracranial lesion. Anidulafungin was initiated in suspicion of mycosis and switched to voriconazole on suspicion of an Aspergillus spp. infection. Progression of the cerebral lesion prompted craniotomy (pod 48) and the aspergillosis was verified. The patient was discharged with oral voriconazole therapy. Re-admission was necessary with acute-on-chronic renal failure after a tacrolimus overdose on pod 130. The patient received a pelvic angiography due to a temperature difference in the legs. It showed a complete iliac artery thrombosis which was subsecutively surgically removed. The histopathological examination revealed an Aspergillus fumigatus conglomerate. The patient died on pod 210 due to systemic aspergillosis. CONCLUSION: The acute development of focal neurologic deficits is common in patients with an aspergillosis of the brain. Nevertheless, arterial thrombosis after Aspergillus fumigatus is less frequent and, to the best of our knowledge, its occurrence after liver transplantation has not yet been reported so far. Due to its rarity, we added a review of the literature to this manuscript.

Real-world effectiveness of 8-week treatment with ledipasvir/sofosbuvir in chronic hepatitis C.

BACKGROUND & AIMS: Ledipasvir/sofosbuvir (LDV/SOF) for 8 to 24 weeks is approved for the treatment of chronic hepatitis C virus infection (HCV). In the ION-3 study, 8 weeks of LDV/SOF was non-inferior to 12 weeks in previously untreated genotype 1 (GT1) patients without cirrhosis. According to the Summary of Product Characteristics (SmPC), 8-week treatment may be considered in naïve non-cirrhotic GT1-patients. However, there are only limited data on the effectiveness of an 8-week regimen of LDV/SOF under real-world conditions. The aim of the present study was to characterise patients receiving 8 weeks of LDV/SOF compared to those receiving 12 weeks of LDV/SOF, and to describe therapeutic outcomes in routine clinical practice. METHODS: The German Hepatitis C-Registry is a large national real-world cohort that analyses effectiveness and safety of antiviral therapies in chronic HCV. This data set is based on 2,404 patients. Treatment with SOF/LDV (without RBV) for 8 or 12 weeks was initiated on or before September 30, 2015. RESULTS: Overall, 84.6% (2,034/2,404) of the safety population (intention-to-treat-1 [ITT1]) and 98.2% (2,029/2,066) of the per protocol (PP) population achieved sustained virological response at week 12 (SVR12). In the 8-week group, 85.1% (824/968) of ITT1 and 98.3% (821/835) of PP patients achieved SVR12, while in the 12-week group, 85.5% (1,210/1,415) of ITT1, and 98.1% (1,208/1,231) of PP patients achieved SVR12. When treated according to the SmPC, 98.7% (739/749) of the patients achieved SVR12 (PP). Relapse was observed in 9.5% (2/21) of cirrhotic patients treated for 8 weeks (PP). CONCLUSIONS: Under real-world conditions a high proportion of eligible patients receiving 8-week LDV/SOF treatment achieved SVR12. Relapse occurred more frequently in patients who did not meet the selection criteria according to the SmPC. LAY SUMMARY: In a large real-world cohort of patients mainly treated by physicians in private practice in Germany, shorter HCV treatment (8-week) resulted in equivalent cure rates to 12-week treatment in genotype 1 HCV-infected patients. Thus, shorter treatment can be recommended in these patients which would substantially reduce costs of therapy. Clinical Trial number: DRKS00009717 (German Clinical Trials Register, DRKS).

Clinical significance of detectable and quantifiable HCV RNA at the end of treatment with ledipasvir/sofosbuvir in GT1 patients.

BACKGROUND & AIMS: AASLD/IDSA treatment guidelines for hepatitis C virus (HCV) infection state that testing for quantitative HCV RNA can be considered at the end of antiviral treatment (EOT) with interferon-free regimens. However, it remains unclear how to respond to a detectable or even quantifiable HCV RNA result. The aim of this study was to analyse the frequency and predictive value of detectable and quantifiable HCV RNA results at the EOT in patients with HCV genotype 1 infection treated with ledipasvir (LDV) and sofosbuvir (SOF) ± ribavirin (RBV) in a large real-world cohort. METHODS: A retrospective analysis of the DHC-R (Deutsches Hepatitis C-Register, German Hepatitis C-Registry) cohort was performed including all patients who were treated with LDV/SOF ± RBV and in whom HCV RNA testing was done with either the Roche COBAS AmpliPrep/COBAS TaqMan (CAP/CTM) or the Abbott RealTime HCV assay (ART). RESULTS: The frequency of detectable HCV RNA at the EOT was 7% in this real-world study involving 471 patients. Furthermore, 3% of the patients (n = 14/471) even had quantifiable viral load at the EOT. Detectable and quantifiable results were more frequent if the ART was used for testing. However, SVR was achieved by 32/33 patients (97%) with detectable and even by all 14 patients (100%) with quantifiable HCV RNA results at the EOT. CONCLUSION: Detectable and even quantifiable HCV RNA results are quite frequent if highly sensitive HCV RNA assays are used. However, treatment prolongation is not indicated, as SVR rates remain high in these patients.

Treatment of HCV genotype 2 with sofosbuvir and ribavirin results in lower sustained virological response rates in real life than expected from clinical trials.

BACKGROUND AND AIMS: Hepatitis C virus (HCV) infections with genotype 2 (GT2) are generally considered as easy to treat. The current standard therapy is 12 weeks of sofosbuvir and ribavirin. However, sustained virological response (SVR) rates varied substantially in distinct subgroups. Therefore, re-assessing the efficacy of interferon-free therapy in cohorts with larger patient numbers is warranted. METHODS: The German Hepatitis C registry is a national multicenter cohort. Patients are treated at the discretion of the physician. Data are collected by a web-based data system and confirmed by plausibility checks and on-site monitoring. RESULTS: A total of 265 (4.3%) of 6034 patients enrolled in the registry were infected with GT2, and 236 had initiated treatment (60% males, 98% Caucasian, median age 54 years). Treatment with sofosbuvir and ribavirin for 12 weeks achieved SVR at week 12 post-treatment (SVR12) in 136/164 (83%) patients. SVR12 rates for this regimen were 80% (35/44) in treatment-experienced patients, 74% (20/27) in cirrhotics and 75% (21/28) in patients with HCV-RNA ≥6 million IU/mL. The overall SVR rate in patients treated with sofosbuvir/ribavirin 12 weeks per protocol (PP), excluding therapy discontinuation or lost to follow-up, was 135/151 (89%). PP SVR12 rates were 91% for treatment naïve, 83% for cirrhotic and 80% for treatment-experienced patients respectively. CONCLUSIONS: In this large GT2 cohort, sofosbuvir and ribavirin for 12 weeks achieved lower SVR rates compared to treatment outcomes expected from phase 3 trials. These findings highlight the need for establishing alternative treatment strategies for GT2 patients, especially in patients with unfavourable outcome factors.

Light shines through the spindrift--phylogeny of African torrent frogs (Amphibia, Anura, Petropedetidae).

Torrent frogs of the genus Petropedetes Reichenow, 1874 as currently understood have a disjunct distribution with species endemic to West, Central or East Africa. We herein present a phylogenetic analysis including all but one of the currently described 12 species of the genus. Maximum Likelihood and Bayesian analyses of combined nuclear (rag1, SIA, BDNF) and mitochondrial (16S, 12S, cytb) genes of more than 3500 base pairs, revealed clades corresponding to the three sub-Saharan regions. Molecular results are confirmed by morphological differences. Surprisingly, the three geographic clades do not form a monophyletic group with respect to closely related families Pyxicephalidae and Conrauidae and therefore require taxonomic changes. We resurrect Arthroleptides Nieden, 1911 for the East African taxa. The Central African taxa remain in the genus Petropedetes. The West African members are placed in the new genus Odontobatrachus gen. nov. The taxonomic position of the new genus remains incertae sedis as it was not assigned to any of the four families included in our analyses. Potential new species have been detected within all three major clades, pointing to a still not fully clarified diversity within African torrent frogs.

The first endemic West African vertebrate family - a new anuran family highlighting the uniqueness of the Upper Guinean biodiversity hotspot.

BACKGROUND: Higher-level systematics in amphibians is relatively stable. However, recent phylogenetic studies of African torrent-frogs have uncovered high divergence in these phenotypically and ecologically similar frogs, in particular between West African torrent-frogs versus Central (Petropedetes) and East African (Arthroleptides and Ericabatrachus) lineages. Because of the considerable molecular divergence, and external morphology of the single West African torrent-frog species a new genus was erected (Odontobatrachus). In this study we aim to clarify the systematic position of West African torrent-frogs (Odontobatrachus). We determine the relationships of torrent-frogs using a multi-locus, nuclear and mitochondrial, dataset and include genera of all African and Asian ranoid families. Using micro-tomographic scanning we examine osteology and external morphological features of West African torrent-frogs to compare them with other ranoids. RESULTS: Our analyses reveal Petropedetidae (Arthroleptides, Ericabatrachus, Petropedetes) as the sister taxon of the Pyxicephalidae. The phylogenetic position of Odontobatrachus is clearly outside Petropedetidae, and not closely related to any other ranoid family. According to our time-tree estimation Odontobatrachus has been separated from other frog lineages since the Cretaceous (90.1 Ma; confidence interval: 84.2-97.1 Ma). Along with this molecular evidence, osteological and external diagnostic characters recognize West African torrent-frogs as distinct from other ranoids and provide strong support for the necessity of the recognition of a new family of frogs. This is the only endemic vertebrate family occurring in the Upper Guinea biodiversity hotspot. CONCLUSION: Based on molecular and morphological distinctiveness, the West African torrent-frog Odontobatrachus natator is allocated to a newly described anuran family. The discovery of an endemic vertebrate family in West Africa highlights the Upper Guinean forests as an outstanding, but highly endangered biodiversity hotspot.

Atezolizumab/bevacizumab and lenvatinib for hepatocellular carcinoma: A comparative analysis in a European real-world cohort.

BACKGROUND: Immunotherapy-based combinations are currently the standard of care in the systemic treatment of patients with HCC. Recent studies have reported unexpectedly long survival with lenvatinib (LEN), supporting its use in first-line treatment for HCC. This study aims to compare the real-world effectiveness of LEN to atezolizumab/bevacizumab (AZ/BV). METHODS: A retrospective analysis was conducted to evaluate the effectiveness and safety of frontline AZ/BV or LEN therapy in patients with advanced HCC across 18 university hospitals in Europe. RESULTS: The study included 412 patients (AZ/BV: n=207; LEN: n=205). Baseline characteristics were comparable between the 2 treatment groups. However, patients treated with AZ/BV had a significantly longer median progression-free survival compared to those receiving LEN. The risk of hepatic decompensation was significantly higher in patients with impaired baseline liver function (albumin-bilirubin [ALBI] grade 2) treated with AZ/BV compared to those with preserved liver function. Patients with alcohol-associated liver disease had poorer baseline liver function compared to other etiologies and exhibited a worse outcome under AZ/BV. CONCLUSIONS: In this real-world cohort, survival rates were similar between patients treated with LEN and those treated with AZ/BV, confirming that both are viable first-line options for HCC. The increased risk of hepatic decompensation in patients treated with AZ/BV who have impaired baseline liver function underscores the need for careful monitoring. Future trials should aim to distinguish more clearly between metabolic dysfunction-associated steatotic liver disease and alcohol-associated liver disease.

From a dwarf to a giant: Revalidation of Callulops valvifer (Barbour, 1910), (Amphibia, Anura, Microhylidae).

According to the most recent revision of the subfamily Asterophryinae, the species Pomatops valvifera was considered to be a synonym of Phrynomantis (now Callulops) robusta. On the basis of recently collected material from near the type locality of Pomatops valvifera on the Bomberai Peninsula in western New Guinea, the invalidity of the genus name is confirmed but the species name is revalidated. Callulops valvifer (new combination) was hitherto unequivocally known from a single specimen of less than 30 mm snout-vent length. With a length of more than 70 mm for males and of more than 80 mm for females, this species is now among the largest of the currently known 22 species of the genus Callulops.

Three ulcerative colitis susceptibility loci are associated with primary sclerosing cholangitis and indicate a role for IL2, REL, and CARD9.

UNLABELLED: Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease characterized by inflammation and fibrosis of the bile ducts. Both environmental and genetic factors contribute to its pathogenesis. To further clarify its genetic background, we investigated susceptibility loci recently identified for ulcerative colitis (UC) in a large cohort of 1,186 PSC patients and 1,748 controls. Single nucleotide polymorphisms (SNPs) tagging 13 UC susceptibility loci were initially genotyped in 854 PSC patients and 1,491 controls from Benelux (331 cases, 735 controls), Germany (265 cases, 368 controls), and Scandinavia (258 cases, 388 controls). Subsequently, a joint analysis was performed with an independent second Scandinavian cohort (332 cases, 257 controls). SNPs at chromosomes 2p16 (P-value 4.12 × 10(-4) ), 4q27 (P-value 4.10 × 10(-5) ), and 9q34 (P-value 8.41 × 10(-4) ) were associated with PSC in the joint analysis after correcting for multiple testing. In PSC patients without inflammatory bowel disease (IBD), SNPs at 4q27 and 9q34 were nominally associated (P < 0.05). We applied additional in silico analyses to identify likely candidate genes at PSC susceptibility loci. To identify nonrandom, evidence-based links we used GRAIL (Gene Relationships Across Implicated Loci) analysis showing interconnectivity between genes in six out of in total nine PSC-associated regions. Expression quantitative trait analysis from 1,469 Dutch and UK individuals demonstrated that five out of nine SNPs had an effect on cis-gene expression. These analyses prioritized IL2, CARD9, and REL as novel candidates. CONCLUSION: We have identified three UC susceptibility loci to be associated with PSC, harboring the putative candidate genes REL, IL2, and CARD9. These results add to the scarce knowledge on the genetic background of PSC and imply an important role for both innate and adaptive immunological factors.

Genetic variation in the PNPLA3 gene is associated with alcoholic liver injury in caucasians.

UNLABELLED: A recent genome-wide study revealed an association between variation in the PNPLA3 gene and liver fat content. In addition, the PNPLA3 single-nucleotide polymorphism rs738409 (M148I) was reported to be associated with advanced alcoholic liver disease in alcohol-dependent individuals of Mestizo descent. We therefore evaluated the impact of rs738409 on the manifestation of alcoholic liver disease in two independent German cohorts. Genotype and allele frequencies of rs738409 (M148I) were determined in 1,043 alcoholic patients with or without alcoholic liver injury and in 376 at-risk drinkers from a population-based cohort. Relative to alcoholic patients without liver damage (n = 439), rs738409 genotype GG was strongly overrepresented in patients with alcoholic liver cirrhosis (n = 210; OR 2.79; P(genotype) = 1.2 × 10(-5) ; P(allelic) = 1.6 × 10(-6) ) and in alcoholic patients without cirrhosis but with elevated alanine aminotransferase levels (n = 219; OR 2.33; P(genotype) = 0.0085; P(allelic) = 0.0042). The latter, biochemically defined association was confirmed in an independent population-based cohort of at-risk drinkers with a median alcohol intake of 300 g/week (OR 4.75; P(genotype) = 0.040; P(allelic) = 0.022), and for aspartate aminotransferase (AST) levels. Frequencies of allele PNPLA3 rs738409(G) in individuals with steatosis and normal alanine aminotransferase (ALT) and AST levels were lower than in alcoholics without steatosis and normal ALT/AST (P(combined) = 0.03). The population attributable risk of cirrhosis in alcoholic carriers of allele PNPLA3 rs738409(G) was estimated at 26.6%. CONCLUSION: Genotype PNPLA3 rs738409(GG) is associated with alcoholic liver cirrhosis and elevated aminotransferase levels in alcoholic Caucasians.

Pregnancy in primary sclerosing cholangitis.

BACKGROUND: There is a paucity of data on fertility or pregnancy in patients with primary sclerosing cholangitis (PSC). OBJECTIVE: To assess fertility in PSC by comparing the number of children in a large cohort of PSC patients to healthy controls and to investigate the outcome of pregnancy, as well as the influence of pregnancy on the disease course. DESIGN: Case series. SETTING: Germany. PARTICIPANTS: 229 PSC patients and 569 healthy controls were evaluated for the number of children. 17 patients with PSC and at least one pregnancy, or who received a diagnosis of PSC within 6 months after delivery, were included in the more detailed analysis. MAIN OUTCOME MEASURES: Number of children per patient and control; disease activity during pregnancy and after delivery including maternal complications; long-term development of live births, fetal loss rate and the influence of medication on fetal and maternal outcome. RESULTS: Fertility did not seem to be reduced in PSC since the number of children did not differ between PSC patients and healthy controls. 25 pregnancies in 17 female PSC patients (median age at conception 31 years) were investigated in detail. An increase in liver enzymes was documented during five pregnancies (20%) and eight times (32%) post-partum. There were no serious maternal complications. All 21 live births presented with a normal perinatal and postnatal development over a median observation time of 50 months. Two pregnancies were delivered pre-term and four fetal losses occurred early in pregnancy (<12 wk). Continuation of treatment with ursodeoxycholic acid (15/21) or azathioprine (2/21) had no negative effects on pregnancy outcome. CONCLUSIONS: Fertility does not seem to be reduced in patients with PSC, who are able to deliver healthy children without an apparent increase in risk for mother or child.

Extensive intrathoracic and intraperitoneal splenosis mimicking mesothelioma: a case report.

BACKGROUND: Splenosis is the heterotopic autotransplantation of splenic tissue after severe splenic trauma and/or splenectomy. The epidemiology is elusive, but splenosis is frequently misdiagnosed as malignant tumors of gastrointestinal, gynecological, or hematological origin before the correct diagnosis is ultimately found. We herein report a rare case of combined, extensive intraabdominal and intrathoracic splenosis initially presenting as pleural mesothelioma. CASE PRESENTATION: A 63-year-old Caucasian male presented with dyspnea and recurring thoracic pain. Initial X-ray and computed tomography scans showed disseminated intrathoracic and intraabdominal lesions. Consequently, thoracoabdominal mesothelioma or a polytopically metastasized cancer of unknown origin was suspected. A thorough examination of the patient's medical history and contrast-enhanced ultrasound by a skilled examiner revealed the diagnosis of extensive abdominal and thoracic splenosis as a consequence of an abdominal gunshot wound with a ruptured diaphragm several decades earlier. Timely diagnosis by noninvasive measures prevented the patient from potential complications of harmful diagnostic procedures, including nuclear imaging and biopsies. The patient is currently treated for hepatitis C and chronic obstructive lung disease, whereas no specific treatment for splenosis is required. CONCLUSIONS: We present a case of rare intrathoracic and intraperitoneal splenosis mimicking mesothelioma. Contrast-enhanced ultrasound and thorough patient history were used for diagnosis and prevented this patient from having to undergo potentially harmful diagnostics. Splenosis can occur after splenic trauma and, consequently, needs to be considered as a rare differential diagnosis to malignant tumors of various origins when a matching patient history is obtained.

Percutaneous creation of direct intrahepatic portosystemic shunts - an alternative for failed TIPS creation.

INTRODUCTION: Direct intrahepatic portosystemic shunt creation is a feasible and safe alternative for transjugular intrahepatic portosystemic shunt creation. It needs equipment like endovascular ultrasound with restricted availability. We performed the procedure percutaneously with a common interventional armamentarium to make it more feasible. METHODS: Retrospective analysis of 8 percutaneous DIPS insertions between 2016 and 2020. RESULTS: The procedure was successful in 8/8 patients. There was no short-term death reported within 30 days. The longest reported patency is 5 years. CONCLUSION: Percutaneous DIPS creation is a feasible alternative for failed TIPS. Percutaneously the procedure can be completed faster than conventional DIPS using only minimal puncture equipment. LEVEL OF EVIDENCE: Level 4, Case Series.

Phosphatidylethanol (PEth) for Monitoring Sobriety in Liver Transplant Candidates: Preliminary Results of Differences Between Alcohol-Related and Non-Alcohol-Related Cirrhosis Candidates.

BACKGROUND Monitoring sobriety is mandatory for liver transplant (LT) candidates with alcohol-related cirrhosis in Germany. Prior to listing, abstinence of 6 months is required. However, little is known about biomarker performance in alcohol-related cirrhosis. Routine testing of ethyl glucuronide in urine (uEtG) or hair (hEtG) is prone to manipulation or is unfeasible in anuria. Phosphatidylethanol (PEth) in dried-blood spots is a promising alternative. We compared PEth with routine parameters and self-reports in alcohol-related and non-alcohol-related cirrhosis at our transplant center. MATERIAL AND METHODS All patients received self-report questionnaires (AUDIT & TLFB). Blood, urine and hair samples, as well as PEth dried-blood spots were drawn at baseline. In addition, survival analyses were conducted. RESULTS Out of 66 patients, 53 were listed for LT and 13 were candidates not listed so far. An alcohol-use disorder was found in 25 patients. Positive results for uEtG, hEtG, and PEth were found in 5/65, 9/65, and 34/66 cases, respectively. PEth positivity was found in 52% of patients with alcohol-related cirrhosis, while 53% of patients with other liver diseases were positive. While uEtG, hEtG, and TLFB correlated with higher PEth values, active waiting list status was significantly correlated with negative PEth values. During the mean follow-up of 41.15 months, 23 patients were transplanted (34.9%). None of the biomarkers significantly predicted survival. CONCLUSIONS PEth can importantly assist abstinence monitoring in LT candidates due to its high validity and objectivity. The high percentage of patients with alcohol consumption in the non-alcoholic liver disease cohort underscores the importance of testing all transplant candidates.

Melanesia holds the world's most diverse and intact insular amphibian fauna.

Identifying hotspots of biological diversity is a key step in conservation prioritisation. Melanesia-centred on the vast island of New Guinea-is increasingly recognised for its exceptionally species-rich and endemic biota. Here we show that Melanesia has the world's most diverse insular amphibian fauna, with over 7% of recognised global frog species in less than 0.7% of the world's land area, and over 97% of species endemic. We further estimate that nearly 200 additional candidate species have been discovered but remain unnamed, pointing to a total fauna in excess of 700 species. Nearly 60% of the Melanesian frog fauna is in a lineage of direct-developing microhylids characterised by smaller distributions than co-occurring frog families, suggesting lineage-specific high beta diversity is a key driver of Melanesian anuran megadiversity. A comprehensive conservation status assessment further highlights geographic concentrations of recently described range-restricted threatened taxa that warrant urgent conservation actions. Nonetheless, by world standards, the Melanesian frog fauna is relatively intact, with 6% of assessed species listed as threatened and no documented extinctions; and thus it provides an unparalleled opportunity to understand and conserve a megadiverse and relatively intact insular biota.
