Fatigue and quality of life in patients with neuroendocrine neoplasia.

INTRODUCTION: Neuroendocrine Neoplasms (NEN) are rare tumours arising in the gastro-intestinal tract or lungs. Poor health related quality of life (HRQoL) is associated with the carcinoid syndrome (CS), but fatigue is also important. We aimed to quantify HRQoL and fatigue in out-patients with NEN. METHODS: In a cross-sectional study, we included 231 patients with NEN (G1-G3). We used pre-validated questionnaires MFI-20, EQ-5D-5L and 85% responded. We collected clinical, biochemical, imaging, and pathology data from Electronic Patient files. Normative values for fatigue and HRQoL were derived from background populations. RESULTS: Median age was 68 years (range 21-91) and 52% were male. Patients with NEN reported more fatigue and worse HRQoL compared to the background population (p < .05). Cured patients reported higher HRQoL than patients with current disease, and patients with high grade neoplasms (G2-G3) reported more anxiety and depression compared to patients with low grade G1 disease (p < .05). The CS resulted in a 9% relative loss in Quality Adjusted Life Years compared to patients without CS. (p < .05). More than 50% of patients with CS reported problems with usual activities, pain/discomfort, and anxiety/depression. Overall, 36% of patients with NEN were fatigued and 92% of these had psychological fatigue. Younger patients (<65 years) experienced more fatigue than older patients (p < .05). CONCLUSION: Patients with NEN report significantly lower HRQoL and more fatigue compared to the background population. Especially, patients with CS had pain, discomfort, anxiety, and depression and a relative reduction in HRQoL. However, compared to other cancer types, patients with NEN experience less fatigue.

Local disease control after stereotactic body radiotherapy in patients with neuroendocrine neoplasms: a cohort study.

BACKGROUND: Neuroendocrine neoplasms represent a diverse group of malignancies. Anatomic origin, histology and aggressiveness vary extensively, from low-grade tumours with an indolent prognosis to highly aggressive conditions with poor outcome. Surgery, with a curative intent, is the standard of treatment when possible. Other treatment regimens include local treatment, or systemic therapy. The role of radiotherapy in treating neuroendocrine neoplasms is not yet established, but studies indicate that a high rate of local control can be achieved by high-dose radiotherapy. Stereotactic body radiotherapy (SBRT) is high dose of radiation delivered to a small volume. We aimed to investigate the one-year local control rate of SBRT in patients with neuroendocrine neoplasms. MATERIAL AND METHODS: Patients with neuroendocrine neoplasms treated with SBRT between 2003 and 2021 were retrospectively identified. Patient characteristics and SBRT-details were collected by review of patient records and the radiotherapy planning charts. All types except for small cell lung cancer and brain metastases were allowed. The prescribed dose was 45-67.8 Gy in three fractions. Progression, both within the target-site and in other sites, was determined based on existing imaging reports. One-year local control rate and systemic control rate was calculated. Descriptive analyses of local response duration, progression-free survival and overall survival were performed. RESULTS: Twenty-one patients were included. The one-year local control rate was 94%. Four of the patients had local progression. All patients receiving SBRT towards their primary tumour (n = 11) had a bronchopulmonary neuroendocrine neoplasm, and a one-year local control rate of 100%. In patients treated at a metastatic target, 80% developed systemic progression but the local control remained high. CONCLUSION: Our study suggests that SBRT may offer a feasible and effective treatment of neuroendocrine neoplasms in selected cases. SBRT provides long-term local stability and may be useful in treating patients with localised disease not fit for surgery.

Nordic 2023 guidelines for the diagnosis and treatment of lung neuroendocrine neoplasms.

Lung neuroendocrine neoplasms (NEN) are a heterogeneous population of neoplasms with different pathology, clinical behavior, and prognosis compared to the more common lung cancers. The diagnostic work-up and treatment of patients with lung- NEN has undergone major recent advances and new methods are currently being introduced into the clinic. These Nordic guidelines summarize and update the Nordic Neuroendocrine Tumor Group's current view on how to diagnose and treat lung NEN-patients and are meant to be useful in the daily practice for clinicians handling these patients. This review reflects our view of the current state of the art of diagnosis and treatment of patients with lung-NEN. Small cell lung carcinoma (SCLC) is not included in these guidelines.

Reduced 3-year risk of hospital admission and mortality after 12-week resistance training of cirrhosis patients: A follow-up of a randomized clinical trial.

BACKGROUND AND AIM: Physical activity confers health benefits in many diseases but remains almost unstudied for cirrhosis. We investigated whether a period of resistance training affects the subsequent long-term risk of hospitalization or mortality among patients with cirrhosis. METHODS: The study includes 39 participants with cirrhosis Child-Pugh class A/B who participated in a prior clinical trial randomized to either resistance training three times per week for 12 weeks or a control group. We gathered data through medical records from trial entry and the following 3 years. The outcomes were time to first hospitalization and all-cause mortality. We used regression models to examine the associations between trial groups and outcomes, adjusting for Child-Pugh class, age, gender, and comorbidity. RESULTS: Nine patients who trained and 15 controls were hospitalized, resulting in a lower risk of first hospitalization in the training group (adjusted subdistribution hazard ratio of 0.40, 95% confidence interval [CI] [0.17, 0.92]; P = 0.03). One patient who trained and six controls died, resulting in a lower all-cause mortality in the training group (adjusted hazard ratio of 0.06, 95% CI [0.01, 0.66]; P = 0.02). CONCLUSION: Twelve weeks of resistance training was associated with a reduced risk of first hospitalization and mortality among patients with cirrhosis Child-Pugh class A/B 3 years after trial entry. The mechanisms of this effect are not identified, and larger studies are warranted.

Low cerebral energy metabolism in hepatic encephalopathy reflects low neuronal energy demand. Role of ammonia-induced increased GABAergic tone.

Hepatic encephalopathy (HE) is a frequent and devastating but generally reversible neuropsychiatric complication secondary to chronic and acute liver failure. During HE, brain energy metabolism is markedly reduced and it remains unclear whether this is due to external or internal energy supply limitations, or secondary to depressed neuronal cellular functions - and if so, which mechanisms that are in play. The extent of deteriorated cerebral function correlates to blood ammonia levels but the metabolic link to ammonia is not clear. Early studies suggested that high levels of ammonia inhibited key tricarboxylic acid (TCA) cycle enzymes thus limiting mitochondrial energy production and oxygen consumption; however, later studies by us and others showed that this is not the case in vivo. Here, based on a series of translational studies from our group, we advocate the view that the low cerebral energy metabolism of HE is likely to be caused by neuronal metabolic depression due to an elevated GABAergic tone rather than by restricted energy availability. The increased GABAergic tone seems to be secondary to synthesis of large amounts of glutamine in astrocytes for detoxification of ammonia with the glutamine acting as a precursor for elevated neuronal synthesis of vesicular GABA.

Prognosis of Patients with Bronchopulmonary Neuroendocrine Neoplasms in a Tertiary Neuroendocrine Tumor Centre of Excellence.

INTRODUCTION: The European Neuroendocrine Tumor Society (ENETS) reports variables of prognostic significance in bronchopulmonary neuroendocrine neoplasms (BP-NENs). The aim of this study was to investigate prognostic factors, recurrence-free survival (RFS), and overall survival (OS) for patients with typical carcinoid (TC), atypical carcinoid (AC), and large-cell neuroendocrine carcinoma (LCNEC). Current follow-up practices vary as the evidence is sparse, and we aimed to explore the relevance of routine bronchoscopy in follow-up. METHODS: This was a cohort study of 208 patients with BP-NENs followed at Aarhus University Hospital in 2008-2019. RFS and OS were determined using the Kaplan-Meier method for the variables such as primary tumor, primary treatment, smoking status, gender, and histological subtypes. RESULTS: The study included 153 patients with TC, 29 with AC, and 26 with LCNEC. Median follow-up was 48 months. The majority of patients (n = 191) received surgical resection, of which 22 (11%) recurred over time. Seventeen patients had nonsurgical treatment, of which 10 (59%) progressed. The 5-year OS rate was 86% for operated and 9% for nonoperated patients (p < 0.05). Patients with TC had a 5-year OS of 90% compared with 63% and 39% for AC and LCNEC, respectively. As for prognostic factors, nonsmokers did not secure a significant difference in OS compared with current/previous smokers (p = 0.51). In the follow-up period, only 2 (9%) of the 22 recurrences were found on a routine bronchoscopy. Both of these recurrences were also found by diagnostic imaging. CONCLUSIONS: Surgical treatment, especially, and diagnosis of TC were associated with a good prognosis. Furthermore, our data did not support routine bronchoscopy as part of a follow-up program for bronchial carcinoids.

Association between fibrosis markers and kidney function following peptide receptor radionuclide therapy in patients with neuroendocrine tumours.

Peptide receptor radionuclide therapy (PRRT) is a treatment for neuroendocrine tumours (NET). Renal impairment is a known side effect due to kidney fibrosis. We investigated the association between novel specific fibrosis markers and kidney function following PRRT. We included 38 patients who had all finished PRRT. In serum and urine, we analysed levels of three different fibrosis markers, PRO-C6 (type VI collagen formation), PRO-C3 (type III collagen formation) and C3M (type III collagen degradation). We determined kidney function by the 51Cr-EDTA plasma clearance. We used Wilcoxon rank sum test and Spearman's rank correlation to evaluate the association between the fibrosis markers and kidney function. We included 38 NET patients, 25 small-intestinal NET, 6 pancreatic NET, 2 pulmonary NET and 5 other types of NET. Median age was 69 years (IQR: 61-73). Median time from last PRRT to inclusion was 8 months (IQR: 3-20). We found significantly increased levels of serum PRO-C6 (p = .007) and urinary PRO-C6 (p = .033) and significantly decreased levels of urinary C3M (p = .035) in patients with impaired kidney function. Further, we observed a negative association between serum PRO-C6 and kidney function (rho = -0.33, p = .04) and a positive association between urinary C3M and kidney function (rho = 0.37, p = .02). We showed an association between the three fibrosis markers, serum PRO-C6, urinary PRO-C6 and urinary C3M and kidney function. These markers may help to improve the understanding of potential pathological tissue turnover and potentially improve monitoring of kidney function after PRRT in NET patients.

Nordic guidelines 2021 for diagnosis and treatment of gastroenteropancreatic neuroendocrine neoplasms.

BACKGROUND: The diagnostic work-up and treatment of patients with gastroenteropancreatic (GEP) neuroendocrine neoplasms (NEN) has undergone major advances and new methods are introduced. Furthermore, an update of the WHO classification has resulted in a new nomenclature for GEP-NEN that is implemented in the clinic. AIM: These Nordic guidelines summarise the Nordic Neuroendocrine Tumour Group's current view on how to diagnose and treat GEP-NEN patients and aims to be useful in the daily practice for clinicians.

Resistance Training Increases Muscle Strength and Muscle Size in Patients With Liver Cirrhosis.

BACKGROUND & AIMS: Cirrhosis is often complicated by reduced muscle mass and strength, which limits the ability to perform daily activities and affects quality of life. Resistance training can increase muscle strength and mass in elderly and chronically ill patients. We performed a randomized controlled trial to investigate whether resistance training increases muscle strength and size in patients with compensated cirrhosis. METHODS: We performed a prospective study of 39 patients with cirrhosis (Child-Pugh class A or B) seen at an outpatient clinic in Denmark from January 2015 through March 2017. Participants protein intake and activity levels were registered daily. Participants were randomly assigned (1:1) to a group that performed 36 1-hour sessions of physical exercise (supervised progressive resistance training for 1 hour, 3 times weekly for 12 weeks) or a control group (no change in daily activity level). Maximal muscle strength was measured as the peak torque in isokinetic knee extension and muscle size was measured as the cross-sectional area of the quadriceps muscle, assessed by magnetic resonance imaging of the thigh. RESULTS: The exercise group increased their muscle strength by 13% (from a mean 119 Nm to 134 Nm)-an 11 Nm greater gain in mean strength than that of the control group (P = .05). The exercise group increased their quadriceps cross-sectional area by 10% (from a mean 58.5 cm2 to 64.6 cm2)-a 4.4 cm2 greater gain than that of the control group (P < .01). The exercise group had significant increases in whole-body lean mass and body cell mass, and significant increases in 6-minute walking distance and the mental component summary of the short form-36 questionnaire. Adverse events were minor and equal between groups. CONCLUSIONS: In a randomized trial of patients with compensated cirrhosis, we found that 12 weeks of supervised progressive resistance training increased muscle strength and size and had beneficial effects on general performance measures, compared with patients who did not change their daily activity routine (control subjects). ClinicalTrials.gov no: NCT02343653.

Prospective Study of Chromogranin A as a Predictor of Progression in Patients with Pancreatic, Small-Intestinal, and Unknown Primary Neuroendocrine Tumors.

BACKGROUND: Retrospective studies are conflicting but most of them report that an increase in plasma chromogranin A (CgA) predicts tumor progression in neuroendocrine tumor (NET) patients. Prospectively, we investigated if a change in plasma CgA is associated with tumor burden changes in NET patients with disseminated disease. METHODS: We included 239 patients treated at 5 NET centers from December 2010 to December 2013. CgA was measured within 6 weeks of a CT or MRI in a patient undergoing at least 2 scan examinations performed over a period of 1-24 months. In a post hoc analysis, CgA measured 3-6 months prior to the CT/MRI was analyzed. Changes in tumor size were evaluated by RECIST1.1. A 25% change in CgA was chosen to discriminate between increased, decreased, or unchanged levels. RESULTS: In 671 events (2 CT/MRI scans and 2 corresponding CgA measurements), we found a weak positive correlation between the RECIST 1.1 responses and change in plasma CgA from baseline (Spearman's rank correlation coefficient: 0.15; p < 0.05). Of 304 events in the post hoc analysis, 58 showed progression, 228 showed stable disease, and 18 showed regression, with a median change in CgA of 19% (IQR: 57 to -20%), -12% (23 to -38%), and -73% (-55 to -83%), respectively. The correlation coefficient for all sites was 0.17 (p = 0.003), and it was 0.16 (p = 0.07), 0.18 (p = 0.04), and 0.20 (p = 0.21) for small-intestinal (n = 137), pancreatic (n = 123), and unknown primary NET (n = 40), respectively. In the 58 patients showing tumor progression, the sensitivity and specificity of an increased CgA concentration were 36 and 82%, respectively, with positive and negative predictive values of 32 and 85%. CONCLUSIONS: In this prospective study of gastroenteropancreatic NET patients, we observed only a weak association between a change in plasma CgA and changes in tumor burden. CgA as a single biomarker was thus inadequate to predict tumor progression.

Effect of proton pump inhibitors on the risk and prognosis of infections in patients with cirrhosis and ascites.

BACKGROUND & AIMS: Many patients with cirrhosis use proton pump inhibitors. We aimed to determine their effects on the risk and prognosis of infections in patients with cirrhosis and ascites. METHODS: We used data from three 1-year trials of satavaptan treatment of ascites (N = 1198) to compare incidence and 90-day mortality of first-time infections between users and nonusers of proton pump inhibitors. With standard and marginal structural Cox models, we adjusted for differences in gender, age, cirrhosis aetiology, Model for End-stage Liver Disease score, serum albumin, lactulose use, severity of ascites, and history of spontaneous bacterial peritonitis or variceal bleeding. RESULTS: During the follow-up, 446 patients had an infection. At inclusion, 524 patients (44%) used proton pump inhibitors, and 645 (54%) used them at some point during the follow-up. Proton pump inhibitor use increased the rate of infections overall (adjusted hazard ratio = 1.43, 95% CI 1.18-1.74), and it also increased the rate of all specific types of infections except upper respiratory tract infections of presumably viral origin. The estimated cumulative risk of infections was 36.4% for proton pump inhibitor users vs 25.1% for nonusers at 6 months (relative risk = 1.45, 95% CI 1.22-1.73), and 45.2% vs 37.7% at 1 year (relative risk = 1.20, 95% 0.97-1.40). Use of proton pump inhibitors did not affect mortality during the 90 days following infection (adjusted hazard ratio = 0.83, 95% CI 0.53-1.31). CONCLUSIONS: Approximately half of patients with cirrhosis and ascites use proton pump inhibitors. This use increases their risk of bacterial infections, but does not affect their prognosis after an infection occurs.

Progressive resistance training prevents loss of muscle mass and strength in bile duct-ligated rats.

BACKGROUND: Loss of muscle mass and strength is common in cirrhosis and increases the risk of hyperammonaemia and hepatic encephalopathy. Resistance training optimizes muscle mass and strength in several chronic diseases. However, the beneficial effects of resistance training in cirrhosis remain to be investigated. Bile duct-ligated (BDL) rats develop chronic liver disease, hyperammonaemia, reduced muscle mass and strength. Our aim was to test the effects of resistance training on muscle mass, function and ammonia metabolism in BDL-rats. METHODS: A group of BDL-rats underwent a progressive resistance training programme and a group of non-exercise BDL-rats served as controls. Resistance training comprised of ladder climbing with a progressive increase in carrying weights attached to the tail. Training was performed 5 days a week during 4 weeks. Muscle strength and body composition were assessed using grip strength and EchoMRI. Weight and circumference of the gastrocnemius muscle (normalized to bodyweight), plasma ammonia and glutamine synthetase protein expression and activity were assessed. RESULTS: BDL + exercise rats had significantly larger gastrocnemius circumference compared to non-exercise BDL-rats: ratio 0.082 vs 0.075 (P < 0.05). Gastrocnemius muscle weight was higher in exercisers than controls: 0.006 vs 0.005 (P < 0.05). A tendency towards a lower plasma ammonia in the exercise group compared to controls was observed (P = 0.10). There were no differences in lean body mass, GS protein expression and activity between the groups. CONCLUSION: Resistance training in rats with chronic liver disease beneficially effects muscle mass and strength. The effects were followed by non-significant reduction in blood ammonia; however, a tendency was observed.

Use of biologically based complementary medicines in patients with neuroendocrine tumors.

Background: Biologically based complementary medicines (BB-CMs) are popular in patients with cancer. However, there are only limited data for BB-CMs in patients with neuroendocrine tumors (NET). We aimed to identify the prevalence and type of BB-CM use and the association to the nutritional risk score (NRS-2002) in NET patients. Methods: We performed a cross-sectional questionnaire study in NET outpatients at the Department of Hepatology and Gastroenterology at Aarhus University Hospital. The nutritional risk was determined by the NRS-2002. Results: We included 186 patients (51% women, median age 66 years). Sixty-six percent were regular BB-CM users. Forty-two percent used at least two supplements. The most popular BB-CMs were vitamin and mineral supplements (47%), calcium and vitamin D (34%). One-third used non-vitamin non-mineral supplements such as fish oil, herbs, Ginger, Q-10, garlic and probiotics. The use of BB-CMs was associated with female gender (48% vs. 37%, p < .05). Intake was significantly more frequent among patients with an NRS score ≥ 3, (60% vs. 76%) and in patients with change in performance status (58% vs. 76%), (p < .05, all). Patients reporting dietary changes used BB-CMs more frequently than patients without dietary changes (61% vs. 77%) (p < .05). Conclusions: In our study, 66% percent of NET patients use BB-CM and 42% used two or more supplements. Vitamins with and without herbal ingredients, minerals, calcium, vitamin D, and fish oil were the most popular supplements. The use of BB-CMs was associated with an NRS score ≥ 3, change in dietary intake, female gender, and change in ECOG performance status.

Cerebral water content mapping in cirrhosis patients with and without manifest HE.

Hepatic encephalopathy (HE) is a frequent and debilitating complication of cirrhosis and its pathogenesis is not definitively clarified. Recent hypotheses focus on the possible existence of low-grade cerebral edema due to accumulation of osmolytes secondary to hyperammonemia. In the present study we investigated increases in cerebral water content by a novel magnetic resonance impedance (MRI) technique in cirrhosis patients with and without clinically manifest HE. We used a 3 T MRI technique for quantitative cerebral water content mapping in nine cirrhosis patients with an episode of overt HE, ten cirrhosis patients who never suffered from HE, and ten healthy aged-matched controls. We tested for differences between groups by statistical non-parametric mapping (SnPM) for a voxel-based spatial evaluation. The patients with HE had significantly higher water content in white matter than the cirrhosis patients (0.6%), who in turn, had significantly higher content than the controls (1.7%). Although the global gray matter water content did not differ between the groups, the patients with HE had markedly higher thalamic water content than patients who never experienced HE (6.0% higher). We found increased white matter water content in cirrhosis patients, predominantly in those with manifest HE. This confirms the presence of increasing degrees of low-grade edema with exacerbation of pathology. The thalamic edema in manifest HE may lead to compromised basal ganglia-thalamo-cortical circuits, in accordance with the major clinical symptoms of HE. The identification of the thalamus as particularly inflicted in manifest HE is potentially relevant to the pathophysiology of HE.

The Risk of Second Primary Colorectal Adenocarcinomas Is Not Increased among Patients with Gastroenteropancreatic Neuroendocrine Neoplasms: A Nationwide Population-Based Study.

BACKGROUND: Second primary colorectal adenocarcinomas (SPCA) may occur with a higher frequency in patients with gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs). In a nationwide population-based study, we investigated the risk of SPCA in GEP-NEN patients and compared it to the general population. METHODS: Using the nationwide Danish registries, we identified 2,831 GEP-NEN patients (median age 63 years [IQR 50-73 years], 53% women) diagnosed in 1995-2010. We used Cox regression to compare the incidence of SPCA in GEP-NEN patients relative to a gender- and age-matched general population sample of 56,044 persons. RESULTS: We observed 20 SPCAs among the 2,831 GEP-NEN patients with a total time at risk of 14,003 years (incidence = 143 per 100,000 person-years) and 770 colorectal adenocarcinomas in the general population of 56,044 persons with a total time at risk of 466,801 years (incidence = 165 per 100,000 person-years). The hazard ratio (HR) of SPCA from GEP-NEN diagnosis to the end of follow-up was 1.22 (95% CI: 0.78-1.92) in GEP-NEN patients compared to the general population. This nonsignificant association was the result of a strong positive association in the first 6 months after diagnosis of GEP-NEN (HR = 9.43 [95% CI: 4.98-17.86]) followed by a negative association in the remainder of the follow-up period (HR = 0.50 [95% CI: 0.20-1.21]). CONCLUSION: In this population-based study, there was no increased risk of SPCA among GEP-NEN patients. The clinical workup in newly diagnosed GEP-NEN patients likely explains the positive short-term association followed by a negative association.

Nutritional status and nutritional risk in patients with neuroendocrine tumors.

BACKGROUND: Malnutrition is frequent among patients with malignancies and associated with impaired function, reduced quality of life and increased mortality. Few data are available in patients with neuroendocrine tumors (NET) on nutritional status, nutritional risk, and nutrition impact symptoms (NIS). We aimed to assess nutritional status (NS) and risk, level of function and associations with NIS in NET patients. METHODS: In a cross-sectional study of NET patients, we measured body mass index (BMI) and handgrip strength (HGS) as markers of NS and muscle function assessed by HGS. The nutritional risk score (NRS) was determined by NRS-2002. NIS was assessed by the eating symptoms questionnaire (ESQ), and disease-related appetite questionnaire (DRAQ). RESULTS: We included 186 patients (51% women), median age 66 years. We observed low BMI (<20.5 kg/m2) in 12%, low HGS in 25%, and impaired level of function in 43% of the patients. About 38% were at nutritional risk, more frequent in patients with residual disease (45% versus 29%, p < .05). Both low HGS, impaired level of function and being at nutritional risk were associated with the NIS: Nausea, vomiting, stomach ache and dry mouth (p < .05) whereas poor appetite and early satiety were only associated with being at nutritional risk and having impaired level of function (p < .05, all). CONCLUSIONS: Almost 40% of NET patients were at nutritional risk; and 25% had impaired HGS associated with specific NIS that preclude food intake. We recommend that NET outpatients are screened with NRS-2002 and that HGS and NIS are determined if NET patients need nutritional therapy.

Update on the Therapeutic Management of Hepatic Encephalopathy.

PURPOSE OF REVIEW: Hepatic encephalopathy (HE) is a common and devastating complication to chronic liver disease. In this paper, we summarize the latest research and evidence of both conventional and up-coming treatments. RECENT FINDINGS: Meta-analyses report beneficial effects of lactulose, branched-chain amino acids, rifaximin, and to some degree L-ornithine L-aspartate on the manifestations of HE in patients with cirrhosis, and generally the numbers needed to treat are low. Recent studies on newer HE treatments including ornithine phenylacetate, spherical carbon, and fecal microbiota transplant also report potentially beneficial effects on HE manifestations. The conventional treatments benefit patients with HE. Newer treatments are under study and more research is needed for their validation.

Physical exercise for people with cirrhosis.

BACKGROUND: Loss of muscle mass and muscle weakness are common complications to cirrhosis and are associated with increased morbidity and mortality. Therefore, physical exercise may benefit people with cirrhosis. OBJECTIVES: To assess the beneficial and harmful effects of physical exercise versus sham exercise or no exercise for people with cirrhosis. SEARCH METHODS: We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE Ovid, Embase Ovid, and three other databases, including manual searches through reference lists, abstracts, and presentations at conferences and meetings, Google Scholar, and online trial registers in February 2018. SELECTION CRITERIA: We included randomised clinical trials regardless of publication status or language. Inclusion criteria were cirrhosis irrespective of the aetiology or stage. Interventions were physical exercise compared with sham exercise or no intervention. DATA COLLECTION AND ANALYSIS: Three review authors independently extracted data. We undertook meta-analyses and presented results using risk ratios (RR) for dichotomous outcomes and mean differences (MD) for continuous outcomes, both with 95% confidence intervals (CI) and I2 values as markers of imprecision and heterogeneity. We assessed bias control using the Cochrane Hepato-Biliary Group domains and determined the credibility of the evidence using GRADE. MAIN RESULTS: We included six randomised clinical trials with 173 participants. All participants had Child-Pugh stage A or B cirrhosis. The intervention groups participated in eight to 14 weeks of physical exercise (aerobic: three trials; resistance: one trial; or aerobic plus resistance training: two trials). Control groups underwent sham exercise (supervised relaxation: one trial) or no intervention (five trials). None of the 89 participants allocated to exercise versus two of 84 participants in the control group died (RR 0.19, 95% CI 0.01 to 3.73; moderate-quality evidence). The cause of death was acute-on-chronic liver disease for both participants. Nine participants in the exercise group and 13 in the control group experienced serious adverse events (RR 0.61, 95% CI 0.19 to 1.94; low-quality evidence).Physical exercise showed no beneficial or detrimental effect on health-related quality of life assessed by the Chronic Liver Disease Questionnaire (MD 0.11, 95% CI -0.44 to 0.67; low-quality evidence). Likewise, physical exercise had no clear effect on physical fitness measured by peak exercise oxygen uptake (MD 0.3 mL/kg/minute, 95 % CI -2.74 to 3.35; low-quality evidence) and Six-Minute Walk Test (MD 56.06 min, 95% CI -9.14 to 121.26; very low-quality evidence). Physical exercise showed no clear effect on mid-thigh circumference (MD 1.76 cm, 95% CI -0.26 to 3.77; low-quality evidence), but showed an increase in mid-arm circumference (MD 2.61 cm, 95% CI 0.36 to 4.85; low-quality evidence). AUTHORS' CONCLUSIONS: We found no clear beneficial or harmful effect of physical exercise on mortality, morbidity, or health-related quality of life. Further evidence is needed to evaluate the beneficial and harmful effects of physical exercise on clinical outcomes.

Proton pump inhibitors as a risk factor for hepatic encephalopathy and spontaneous bacterial peritonitis in patients with cirrhosis with ascites.

UNLABELLED: Proton pump inhibitors (PPIs) may be a risk factor for hepatic encephalopathy (HE) in patients with cirrhosis, possibly through translocation of gut bacteria, which can also lead to spontaneous bacterial peritonitis (SBP). We examined the associations between PPIs and development of HE or SBP in patients with cirrhosis with ascites. We used data from three 1-year trials of satavaptan for ascites control. We used Cox regression to compare HE and SBP rates between users and nonusers of PPIs. At inclusion, 39% of the 865 patients with cirrhosis with ascites used PPIs, 52% used them at some point during the follow-up, and the proportion of current users was always in the 30%-39% range. There were 189 first-time HE episodes during the follow-up, and the cumulative 1-year risk was 31% for those who used PPIs at baseline versus 25% for those who did not. The confounder-adjusted hazard ratio (HR) of HE for current PPI use versus current nonuse was 1.36 (95% confidence interval [CI], 1.01-1.84). The HR for overt HE was higher (adjusted HR = 1.88; 95% CI, 1.21-1.91). During the follow-up, 86 patients developed SBP. The adjusted HR of SBP for current PPI users versus nonusers was 1.72 (95% CI, 1.10-2.69). CONCLUSION: PPIs were used by 52% of this international cirrhosis cohort during a 1-year period and was a risk factor for developing HE and SBP. These findings are consistent with the hypothesis that PPIs may increase translocation of gut bacteria. (Hepatology 2016;64:1265-1272).

A descriptive cross-sectional study of pain in patients with neuroendocrine tumors.

OBJECTIVE: Neuroendocrine tumors (NET) are rare cancer forms, which are often disseminated at diagnosis. In cancer patients, pain is a feared symptom and reported in 30% of patients during treatment and in 70-90% with advanced disease. However, the extent and the severity of pain in patients with NET have never been investigated. MATERIAL AND METHODS: We conducted a cross-sectional survey of 207 NET patients in the period March 2014 to March 2015 at our tertiary NET Center. We used a questionnaire to investigate the prevalence, severity and character of pain along with demographic, clinical and pathological data from medical records. RESULTS: One hundred and 37 patients had undergone surgery (66%) of which 95 patients (69%) were considered cured and 112 patients had residual disease after surgery or comorbidity at diagnosis that contradicted surgery. Eighty-five patients (41%) reported any pain within the past week; the median pain intensity (numerical rating scale 0-10) was 5.0. Forty-seven (23%) of all included patients reported pain within the past week that developed in relation to NET or its treatment and 51% of these had pain descriptors consistent with neuropathic pain. The median level of plasma chromogranin A in patients with pain was significantly higher compared to patients without pain (p < .05). CONCLUSIONS: A considerable proportion of our NET patients suffered from pain with moderate intensity and did not receive adequate pain treatment. Screening for pain should therefore be performed during NET follow-up visits and specific pain treatment should be considered.
