Prevalence of Frailty and Its Impact on Mortality and Hospitalization in Patients With Cirrhosis: A Systematic Review and Meta-analysis

Background & aims

Frailty in patients with cirrhosis is associated with increased morbidity and mortality. In this study, we aimed to determine the prevalence of frailty and its impact on mortality and hospitalization in patients with cirrhosis.

Methods

An elaborate search was undertaken in the databases "PubMed, Scopus, Web of Science, and Cochrane, and preprint servers", and an assessment of all published articles till 17 February 2023 was done. Studies that provided data on prevalence, mortality and hospitalization among frail patients with cirrhosis were included. The study characteristics and data on the prevalence, mortality, and hospitalization were extracted from included studies. The primary outcome was to estimate the pooled prevalence of frailty and determine its impact on mortality and hospitalization in patients with cirrhosis.

Results

Overall, 12 studies were included. Data on prevalence of frailty and mortality were available in 11 studies, while seven studies reported data on hospitalization. The analysis conducted among 6126 patients with cirrhosis revealed pooled prevalence of frailty to be 32% (95% confidence interval [CI], 24-41). A total of 540 events of death revealed a pooled mortality rate of 29% (95% CI, 19-41). Six-month and twelve-month pooled estimates of mortality were found to be 24% (95% CI, 17-33) and 33% (95% CI, 23-45), respectively. The pooled hospitalization rate among the seven studies was 43% (95% CI, 21-68).

Conclusion

The prevalence of frailty in patients with cirrhosis is high, leading to poor outcomes. Frailty assessment should become an integral part of cirrhosis evaluation.

Exploring the Prevalence, Predictors, and Impact of Bacterial Infections to Guide Empiric Antimicrobial Decisions in Cirrhosis (EPIC-AD)

Background/Aims

This study delved into cirrhosis-related infections to unveil their epidemiology, risk factors, and implications for antimicrobial decisions.

Methods

We analyzed acutely decompensated cirrhosis patients (n = 971) from North India between 2013-2023 at a tertiary center. Microbiological and clinical features based on infection sites (EASL criteria) and patient outcomes were assessed.

Results

Median age was 45 years; 87% were males with 47% having alcoholic hepatitis. Of these, 675 (69.5%) had infections; 305 (45%) were culture-confirmed. Notably, 71% of confirmed cases were multi-drug resistant organisms (MDRO)-related, chiefly carbapenem-resistant (48%). MDRO prevalence was highest in pulmonary (80.5%) and skin-soft-tissue infections (76.5%). Site-specific distribution and antimicrobials were suggested. Predictive models identified prior hospitalization [OR:2.23 (CI:1.58-3.14)], norfloxacin prophylaxis [OR:2.26 (CI:1.44-3.55)], prior broad-spectrum antibiotic exposure [OR:1.61 (CI:1.12-2.30)], presence of systemic inflammatory response-SIRS [OR:1.75 (CI: 1.23-2.47)], procalcitonin [OR:4.64 (CI:3.36-6.40)], and HE grade [OR:1.41 (CI:1.04-1.90)], with an area under curve; AUC of 0.891 for infection prediction. For MDRO infection prediction, second infection [OR: 7.19 (CI: 4.11-12.56)], norfloxacin prophylaxis [OR: 2.76 (CI: 1.84-4.13)], CLIF-C OF [OR: 1.10 (CI: 1.01-1.20)], prior broad-spectrum antibiotic exposure [OR: 1.66 (CI: 1.07-2.55)], rifaximin [OR: 040 (0.22-0.74)] multisite [OR: 3.67 (CI: 1.07-12.56)], and polymicrobial infection [OR: 4.55 (CI: 1.45-14.17)] yielded an AUC of 0.779 and 93% specificity. Norfloxacin prophylaxis, multisite infection, mechanical ventilation, prior broad-spectrum antibiotic exposure, and infection as acute precipitant predicted carbapenem-resistant infection (AUC: 0.821). Infections (culture-proven or probable), MDROs, carbapenem/pan-drug resistance, and second infections independently linked with mortality (P < 0.001), adjusted for age, leucocytosis, and organ failures. A model incorporating age [HR:1.02 (CI: 1.01-1.03), infection [HR:1.52 (CI: 1.05-2.20)], prior hospitalization [HR:5.33 (CI: 3.75-7.57)], norfloxacin [HR:1.29 (CI: 1.01-1.65)], multisite infection [HR:1.47 (CI:1.06-2.04)], and chronic liver failure consortium-organ failure score; CLIF-C OF [HR:1.17 (CI: 1.11-1.23)] predicted mortality with C-statistics of 0.782 (P < 0.05).

Conclusion

High MDRO burden, especially carbapenem-resistant, necessitates urgent control measures in cirrhosis. Site-specific epidemiology and risk models can guide empirical antimicrobial choices in cirrhosis management.

Evaluation of terlipressin-related patient outcomes in hepatorenal syndrome-acute kidney injury using point-of-care echocardiography

BACKGROUND AND AIMS

Treatment of hepatorenal syndrome-acute kidney injury (HRS-AKI), with terlipressin and albumin, provides survival benefits, but may be associated with cardiopulmonary complications. We analyzed the predictors of terlipressin response and mortality using point-of-care echocardiography (POC-Echo) and cardiac and renal biomarkers.

APPROACH

Between December 2021 and January 2023, patients with HRS-AKI were assessed with POC-Echo and lung ultrasound within 6 hours of admission, at the time of starting terlipressin (48 h), and at 72 hours. Volume expansion was done with 20% albumin, followed by terlipressin infusion. Clinical data, POC-Echo data, and serum biomarkers were prospectively collected. Cirrhotic cardiomyopathy (CCM) was defined per 2020 criteria.

RESULTS

One hundred and forty patients were enrolled (84% men, 59% alcohol-associated disease, mean MELD-Na 25±SD 5.6). A median daily dose of infused terlipressin was 4.3 (interquartile range: 3.9-4.6) mg/day; mean duration 6.4 ± SD 1.9 days; the complete response was in 62% and partial response in 11%. Overall mortality was 14% and 16% at 30 and 90 days, respectively. Cutoffs for prediction of terlipressin nonresponse were cardiac variables [ratio of early mitral inflow velocity and mitral annular early diastolic tissue doppler velocity > 12.5 (indicating increased left filling pressures, C-statistic: 0.774), tissue doppler mitral velocity < 7 cm/s (indicating impaired relaxation; C-statistic: 0.791), > 20.5% reduction in cardiac index at 72 hours (C-statistic: 0.885); p < 0.001] and pretreatment biomarkers (CysC > 2.2 mg/l, C-statistic: 0.640 and N-terminal proBNP > 350 pg/mL, C-statistic: 0.655; p <0.050). About 6% of all patients with HRS-AKI and 26% of patients with CCM had pulmonary edema. The presence of CCM (adjusted HR 1.9; CI: 1.8-4.5, p = 0.009) and terlipressin nonresponse (adjusted HR 5.2; CI: 2.2-12.2, p <0.001) were predictors of mortality independent of age, sex, obesity, DM-2, etiology, and baseline creatinine.

CONCLUSIONS

CCM and reduction in cardiac index, reliably predict terlipressin nonresponse. CCM is independently associated with poor survival in HRS-AKI.

APASL clinical practice guidelines on the management of acute kidney injury in acute-on-chronic liver failure

Acute-on-chronic liver failure (ACLF) is a syndrome that is characterized by the rapid development of organ failures predisposing these patients to a high risk of short-term early death. The main causes of organ failure in these patients are bacterial infections and systemic inflammation, both of which can be severe. For the majority of these patients, a prompt liver transplant is still the only effective course of treatment. Kidneys are one of the most frequent extrahepatic organs that are affected in patients with ACLF, since acute kidney injury (AKI) is reported in 22.8-34% of patients with ACLF. Approach and management of kidney injury could improve overall outcomes in these patients. Importantly, patients with ACLF more frequently have stage 3 AKI with a low rate of response to the current treatment modalities. The objective of the present position paper is to critically review and analyze the published data on AKI in ACLF, evolve a consensus, and provide recommendations for early diagnosis, pathophysiology, prevention, and management of AKI in patients with ACLF. In the absence of direct evidence, we propose expert opinions for guidance in managing AKI in this very challenging group of patients and focus on areas of future research. This consensus will be of major importance to all hepatologists, liver transplant surgeons, and intensivists across the globe.

A Review onthe Use of Modern Computational Methods in Alzheimer's Disease-Detection and Prediction

Discoveries in the field of medical sciences are blooming rapidly at the cost of voluminous efforts. Presently, multidisciplinary research activities have been especially contributing to catering cutting-edge solutions to critical problems in the domain of medical sciences. The modern age computing resources have proved to be a boon in this context. Effortless solutions have become a reality, and thus, the real beneficiary patients are able to enjoy improved lives. One of the most emerging problems in this context is Alzheimer's disease, an incurable neurological disorder. For this, early diagnosis is made possible with benchmark computing tools and schemes. These benchmark schemes are the results of novel research contributions being made intermittently in the timeline. In this review, an attempt is made to explore all such contributions in the past few decades. A systematic review is made by categorizing these contributions into three folds, namely, First, Second, and Third Generations. However, priority is given to the latest ones as a handful of literature reviews are already available for the classical ones. Key contributions are discussed vividly. The objectives set for this review are to bring forth the latest discoveries in computing methodologies, especially those dedicated to the diagnosis of Alzheimer's disease. A detailed timeline of the contributions is also made available. Performance plots for certain key contributions are also presented for better graphical understanding.

Machine learning improves the prediction of significant fibrosis in Asian patients with metabolic dysfunction-associated steatotic liver disease - The Gut and Obesity in Asia (GO-ASIA) Study

BACKGROUND

The precise estimation of cases with significant fibrosis (SF) is an unmet goal in non-alcoholic fatty liver disease (NAFLD/MASLD).

AIMS

We evaluated the performance of machine learning (ML) and non-patented scores for ruling out SF among NAFLD/MASLD patients.

METHODS

Twenty-one ML models were trained (N = 1153), tested (N = 283), and validated (N = 220) on clinical and biochemical parameters of histologically-proven NAFLD/MASLD patients (N = 1656) collected across 14 centres in 8 Asian countries. Their performance for detecting histological-SF (≥F2fibrosis) were evaluated with APRI, FIB4, NFS, BARD, and SAFE (NPV/F1-score as model-selection criteria).

RESULTS

Patients aged 47 years (median), 54.6% males, 73.7% with metabolic syndrome, and 32.9% with histological-SF were included in the study. Patients with SFvs.no-SF had higher age, aminotransferases, fasting plasma glucose, metabolic syndrome, uncontrolled diabetes, and NAFLD activity score (p < 0.001, each). ML models showed 7%-12% better discrimination than FIB-4 to detect SF. Optimised random forest (RF) yielded best NPV/F1 in overall set (0.947/0.754), test set (0.798/0.588) and validation set (0.852/0.559), as compared to FIB4 in overall set (0.744/0.499), test set (0.722/0.456), and validation set (0.806/0.507). Compared to FIB-4, RF could pick 10 times more patients with SF, reduce unnecessary referrals by 28%, and prevent missed referrals by 78%. Age, AST, ALT fasting plasma glucose, and platelet count were top features determining the SF. Sequential use of SAFE < 140 and FIB4 < 1.2 (when SAFE > 140) was next best in ruling out SF (NPV of 0.757, 0.724 and 0.827 in overall, test and validation set).

CONCLUSIONS

ML with clinical, anthropometric data and simple blood investigations perform better than FIB-4 for ruling out SF in biopsy-proven Asian NAFLD/MASLD patients.

Bloody Lips - Gluing Bleeding Lower Lip Spider Angioma in Decompensated Cirrhosis

Spider angiomas are dilated vascular channels in the skin. They have a central arteriole with surrounding vascular channels resembling legs of a spider, hence the name. They are frequently associated with liver cirrhosis, thyrotoxicosis, and pregnancy. We present the case of a 49-year-old gentleman who was referred to our liver clinic with complaints of jaundice and ascites of one-month duration. The patient was a chronic alcohol consumer, consuming country-made liquor, 80-100 grams/day for past 8-10 years. He was diagnosed with Acute on chronic liver failure with a model for end-stage liver disease score of 38. During his hospital stay, he developed active spurting from a spider angioma on his lower lip (video 1), which was initially tackled with hand compressions, which stopped bleeding for a few minutes, restarting again after the compressions were lifted. It was then decided to inject 0.1 mL cyanoacrylate glue injection using a 21-gauge needle, immediately stopping active spurt (video 2), (Figure 1). A small ulcer formed at the injection site, which healed in few days, and the patient was discharged to home. Spider angiomas are characteristic cutaneous manifestation of liver cirrhosis with a specificity of 95%.1 The prevalence of spider angiomas in cirrhosis is reported to be around 30-40%. Li Hongyu et al. in their study on 198 individuals reported the prevalence to be 47%.2 They can be graded from grade 1+ (readily recognizable containing a body, legs, and surrounding erythema) to grade 4+ (visible pulsations with a hand lens and raised central punctum with many obvious "spider legs" radiating from it).3 Underlying pathogenesis in cirrhosis is multifactorial including decrease levels of testosterone and high levels of estradiol,4 hyperdynamic circulation, high levels of substance-P, and vascular endothelial growth factor leading to angiogenesis and vasodilation.5,6 Spider angiomas can be single or multiple and are usually seen in the territory of superior vena cava-the face (nose, lips, forehead), upper chest, and arms.2 These lesions have been associated with bleeding esophageal varices and hepatopulmonary syndrome. Bleeding from spider angiomas is unusual. Rarely, fine-needle electrocautery, potassium-titanyl-phosphate (KTP) laser, or electro desiccation has been used to clear spider angiomas for cosmetic concerns. Treatment includes hand or ice compressions and treating the underlying cause. Use of cyanoacrylate glue for bleeding spider angioma has not been reported in the literature. We think this can be a handy bedside tool to combat an active spurt of bleeding when conventional methods have failed, as in our case; however, further studies are warranted.

Growth Hormone Therapy in Decompensated Cirrhosis: An Open-Label, Randomized Control Trial

INTRODUCTION

Effect of long-term growth-hormone (GH) therapy in decompensated cirrhosis (DC) is unknown. We studied the safety and efficacy of GH therapy on malnutrition, nitrogen metabolism, and hormonal changes in patients with DC.

METHODS

Patients with DC were randomized to standard medical therapy plus GH (group A; n = 38) or standard medical therapy alone (group B; n = 38). Body mass index, midarm muscle circumference (MAMC), hand grip strength (HGS), liver frailty index (LFI), skeletal muscle index (SMI), nitrogen balance, Child-Turcotte-Pugh, model for end-stage liver disease, quality of life (QOL), serum albumin, GH, insulin like growth factor-1, and acid labile subunit (ALS) were assessed at baseline and at 12 months.

RESULTS

The mean difference between baseline and 12-months in SMI (-6.122 [-9.460 to -2.785] cm 2 /m 2 ), body mass index (-2.078 [-3.584 to -0.5718] kg/m 2 ), MAMC (-1.960 [-2.928 to -0.9908] cm), HGS (-5.595 [-7.159 to -4.031] kg), albumin (-0.3967 [-0.6876 to -0.1057] g/dL), LFI (0.3328 [0.07786-0.5878]), Child-Turcotte-Pugh (0.9624 [0.1435-1.781]), model for end-stage liver disease (1.401 [0.04698-2.75]), insulin-like growth factor-1 (-6.295 [-11.09 to -1.495] ng/dL), and ALS (-8.728 [-14.12 to -3.341] pg/mL) were statistically significantly better ( P < 0.05) in group A. There was no improvement in nutritional parameters, clinical scores, QOL scores, or nitrogen balance in group B. The mean difference between group A and B in SMI, HGS, MAMC, LFI, ALS, physical component summary, and mental component summary at 12 months was also statistically significant. Survival at 12 months was similar in both groups ( P = 0.35). No serious adverse events were observed.

DISCUSSION

Long-term use of GH is safe in DC and leads to improvement in malnutrition and possibly QOL. However, there is no improvement in 12-month survival (NCT03420144).

Poor Performance of Non-invasive Tests for Advanced Fibrosis in Nonalcoholic Fatty Liver Disease: A Multicentric Asian Study

BACKGROUND

Non-invasive tests (NITs) are useful to assess advanced fibrosis (AF) in nonalcoholic fatty liver disease (NAFLD). Data from Asian countries suggest that these tests have poor performance. We aimed to assess diagnostic accuracy of established thresholds of biomarker-based NITs and Transient Elastography (TE) in identifying AF and evaluated the utility of a two-step test approach.

METHODS

Biopsy-proven 641 NAFLD patients (55.2% males, median age 42 years) were included from three different centers of Asia. AF (≥ F3) was identified as per histological staging (24.8%).

RESULTS

TE had the highest area under the receiver operating characteristic curve (AUROC) 0.82 (0.79-0.86), and all other biomarker-based NITs had low AUROC (< 0.7). NITs performed poorly at established thresholds. The combination of NITs utilizing liver stiffness measurement (LSM) and biomarkers, Agile 3+ and FAST, demonstrated acceptable diagnostic accuracy (AUROC 0.82 and 0.78, respectively), but none were superior to LSM alone. LSM measured using appropriate M and XL probes remained accurate regardless of body mass index (BMI); NFS and APRI scores were less accurate at higher BMI ranges. A two-step approach using NFS rule-out criteria (< - 2.97 to rule out) followed by LSM (< 7.3 kPa to rule out and ≥ 12.7 kPa to rule in) correctly classified 62.4% of patients, with only 10.2% of patients incorrectly classified.

CONCLUSION

NITs have not been validated to identify AF in the Asian NAFLD population, and internationally accepted thresholds yield high false-negative rates. LSM and LSM-based combination tests remain the most accurate.

Cirrhotic cardiomyopathy influences clinical outcomes and enhances performance of conventional risk prediction models in acute-on-chronic liver failure with severe sepsis

BACKGROUND

Point-of-care echocardiography (POC-Echo) is an essential intensive care hemodynamic monitoring tool.

AIMS

To assess POC-Echo parameters [i.e., cardiac index (CI), systemic vascular resistance index (SVRI) and cirrhotic cardiomyopathy (CCM) markers] and serum biomarkers in predicting circulatory failure (need for vasopressors) and mortality in patients with acute-on-chronic liver failure (ACLF) having sepsis-induced hypotension.

METHODS

We performed serial POC-Echo within 6 hours (h) of presentation and subsequently at 24, 48 and 72 h in patients with ACLF and sepsis-induced hypotension admitted to our liver intensive care unit. Clinical data, POC-Echo data and serum biomarkers were collected prospectively.

RESULTS

We enrolled 120 patients [59% men, aged 49 ± 12 years, 56% alcohol-related disease and median MELDNa of 30 (27-32)], of whom 68 (56.6%) had circulatory failure, with overall mortality of 60%. CCM was present in 52.5%. The predictors of circulatory failure were CI (aHR -1.5; p = 0.021), N-terminal brain natriuretic peptide (aHR -1.1; p = 0.007) and CCM markers; e' septal mitral velocity (aHR -0.5; p = 0.039) and E/e' ratio (aHR -1.2; p = 0.045). Reduction in CI by 20% and SVRI by 15% at 72 h predicted mortality with a sensitivity of 84% and 72%, and specificity 76% and 65%, respectively (p < 0.001). The MELD-CCM model and CLIF-CCM model were computed as MELDNa + 1.815 × E/e' (septal) + 0.402 × e' (septal) and CLIF-C ACLF + 1.815 × E/e' (septal) + 0.402 × e' (septal), respectively, based on multivariable logistic regression. Both scores outperformed MELDNa (z-score = -2.073, p = 0.038) and CLIF-C ACLF score (z score = -2.683, p-value = 0.007), respectively, in predicting 90-day mortality.

CONCLUSION

POC-Echo measurements such as CCM markers (E/e' and e' velocity) and change in CI reliably predict circulatory failure and mortality in ACLF with severe sepsis. CCM markers significantly enhanced the CLIF-C ACLF and MELDNa predictive performance.

Intravenous BCAA Infusion Does Not Lead to a Sustained Recovery From Overt HE in ACLF - An Open Label Randomized Clinical Trial

Background

Hepatic encephalopathy (HE) in acute-on-chronic liver failure (ACLF) is associated with significant morbidity and mortality. We conducted a prospective, randomized controlled clinical trial to study the efficacy of intravenous branched chain amino acids (IV-BCAA) with lactulose versus lactulose alone for improvement in HE at 24 h, day 3, and day 7. The primary outcome was an improvement in encephalopathy by ≥ 1 grade at 72 h.

Patients and methods

European association for study of liver (EASL) defined ACLF patients with overt HE were assessed and randomized into the experimental arm (IV-BCAA - 500 mL/day for 3 days + Lactulose; n = 39) and the comparator arm (Lactulose alone; n = 37). Six patients developed COVID-19 after randomization and were excluded (4-experimental arm and 2-comparator arm).

Results

Of 222 screened patients, 70 (35 in each arm) were included in the analysis. Baseline characteristics, including HE grade (2.9 ± 0.7 vs 2.8 ± 0.7; P = 0.86) and (chronic liver failure) CLIF-C ACLF score (54.2 ± 5.6 vs 54.8 ± 5.7; P = 0.65), were similar. Overall survival was 40% at 28 days (48.5% vs 31.4%; P = 0.14). Improvement in hepatic encephalopathy scoring algorithm (HESA) by ≥ 1 grade at 24 h occurred in 14 patients (40%) in the BCAA arm and 6 patients (17.1%) in the control group (P = 0.03) which translated to a shorter intensive care unit (ICU) stay. The median change in HESA at 24 h was greater in the BCAA arm than the control arm (P = 0.006), which was not sustained at days 3 or 7. Ammonia levels did not correlate with the grade of HE (Spearman's correlation coefficient (ρ) = - 0.0843; P = 0.29).

Conclusion

Intravenous BCAA does not lead to a sustained improvement in HE grade in ACLF.

Trial registration no

Prevalence, Risk Factors, and Impact of Bacterial or Fungal Infections in Acute Liver Failure Patients from India

BACKGROUND

We evaluated the prevalence, risk factors, and impact of bacterial/fungal infections in acute liver failure (ALF) patients.

METHODS

We analyzed clinical, biochemical, and microbiological data of ALF patients with and without bacterial/fungal infections admitted at an institute over the last 5 years.

RESULTS

We enrolled 143 patients, 50% males, median age 25 years, with acute viral hepatitis (32.2%), drug-induced injury (18.2%), and tropical illness (14%) as aetiologies of ALF. 110 patients (76.9%) developed bacterial/fungal infections [Bacterial infection: MDR: 70%, PDR: 7%, ESBL: 40%, CRE: 30%, CRAB: 26.6%, MDR-EF: 13.3% and fungal infection: 19 (17.3%)]. On univariable analysis, SIRS (33.6% vs.3%), ICU admission (78.2% vs. 45.5%), mechanical ventilation (88.2% vs. 51.5%), inotropes (39.1% vs. 6.1%), invasive catheters (91.8% vs. 39.4%), and prolonged catheterization (6 days vs. 0 days) were significant risk factors for infections (p < 0.05, each). In contrast, SIRS and catheterization independently predicted infection on multivariable regression. Organ failures [3 (2-4) vs. 1 (0-2)], grade-III-IV HE (67.3% vs. 33.3%), circulatory failure (39.1% vs. 6.1%), coagulopathy (INR > 2.5: 58.2% vs. 33.3%), renal injury (28.2% vs. 6.1%) (p < 0.05), MELD (32.9 ± 8.2 vs. 26.7 ± 8.3) and CPIS [3(2-4) vs. 2(0-2)] were higher in infected vs. non-infected patients (p < 0.001). 30-day survival was significantly lower in infected vs. non-infected patients (17.3% vs. 75.8%, p < 0.001), while no patient survived with fungal infections. Refractory septic shock was the commonest cause of mortality in patients.

CONCLUSIONS

Infections due to MDR organisms are high, fungal infections are fatal, and refractory septic shock is the dominant reason for mortality, implying bacterial and fungal infections as the major killer in ALF patients.

Endoscopic Ultrasound-Guided Transgastric Shunt Obliteration for Recurrent Hepatic Encephalopathy

INTRODUCTION

Occlusion of spontaneous portosystemic shunts (SPSSs) in patients with cirrhosis may be required in recurrent or refractory hepatic encephalopathy. We describe a novel method for occlusion of SPSS using endoscopic ultrasound (EUS).

METHODS

EUS-guided transgastric shunt obliteration was performed by injecting glue and coils directly into SPSS.

RESULTS

EUS-guided transgastric shunt obliteration was performed for 7 patients in 9 sessions. Complete cessation of Doppler flow was achieved in 6/7 cases. Adequate clinical response was observed in 6/7 patients. No procedure-related severe adverse events were seen.

DISCUSSION

This novel technique is a potentially effective and efficient method for shunt obliteration.

Lean Indian patients with non-alcoholic fatty liver disease (NAFLD) have less metabolic risk factors but similar liver disease severity as non-lean patients with NAFLD

INTRODUCTION

Although most patients with NAFLD are obese or overweight, some are lean with normal BMI. Our aim was to assess differences in clinicopathological profile and liver disease severity among lean and non-lean NAFLD.

METHODS

Data of 1040 NAFLD patients over last 10 years was analysed. BMI < 23 kg/m2 categorised lean patients. Non-invasive assessment of steatosis was done by ultrasound and controlled attenuation parameter (CAP) while fibrosis was assessed with FIB-4 and liver stiffness measurement (LSM). FibroScan-AST (FAST) score was used for non-invasive prediction of NASH with significant fibrosis. Histology was reported using NASH-CRN system.

RESULTS

149 (14.3%) patients were lean while 891 (85.7%) patients were non-lean. Diabetes mellitus [25 (16.7%) vs 152 (17.05%), p > 0.99], elevated triglycerides [81 (54.3%) vs 525 (58.9%), p = 0.33] and low HDL [71(47.6%) vs 479(53.7%), p = 0.18] were observed in a similar proportion. Lean patients were less likely to have central obesity [72 (48.3%) vs 788 (88.4%), p < 0.001], hypertension [16 (10.7%) vs 239(26.8%), p < 0.001] and metabolic syndrome [21 (14.09%) vs 290 (32.5%), p < 0.001]. No difference in steatosis assessment was noted using ultrasound (p = 0.55) or CAP (0.11). FAST [0.38 (0.18-0.66) vs 0.39 (0.27-0.73), p = 0.53], FIB-4 [1.08 (0.65-1.91) vs 1.09 (0.66-1.94), p = 0.94] and LSM [6.1 (4.8-7.9) vs 6.2 (4.7-8.6), p = 0.19) were similar. Liver biopsy was available in 149 patients [lean: 19 (12.7%), non-lean: 130 (87.3%)]. There was no difference in the number of patients with NASH [4 (21.05%) vs 20 (15.3%), p = 0.51], significant fibrosis [2 (10.5%) vs 32 (24.6%), p = 0.25] or advanced fibrosis [1 (5.26%) vs 18 (13.84%), p = 0.47].

CONCLUSION

Although metabolic co-morbidities are less common, there is no difference in liver disease severity among both groups.

Assessment of Sarcopenia Using Muscle Ultrasound in Patients With Cirrhosis and Sarcopenic Obesity (AMUSE STUDY)

BACKGROUND AND AIMS

Sarcopenic obesity (SO) marks a confluence of 2 complex entities involving the muscle-liver-adipose tissue axis. Computed tomographic (CT) scan-derived skeletal muscle index (SMI) remains the gold standard for sarcopenia assessment in SO. However, it has intrinsic limitations of cost, radiation, and point of care applicability. We assessed the role of muscle ultrasound (US) in SO.

METHODS

A total of 52 patients with cirrhosis and obesity were assessed for sarcopenia using SMI. US assessment of thigh and forearm muscles was done to record quadriceps muscle thickness (QMT), quadriceps feather index (QMFI), forearm muscle thickness (FMT), and forearm feather index (FFI), respectively. Evaluated US parameters were correlated with SMI and assessed for diagnostic accuracy using the area under the curve.

RESULTS

A total of 40 (76.9%) males and 12 (23.1%) females [mean age: 50.9 y (43.8 to 53.5 y)] were included. QMT [0.45 cm/m 2 (0.42 to 0.48 cm/m 2 ) vs. 0.67 cm/m 2 (0.63 to 0.70 cm/m 2 )], QMFI [0.82 cm/m 2 (0.77 to 0.87 cm/m 2 ) vs. 1.12 cm/m 2 (1.06 to 1.19 cm/m 2 )], FMT [0.19 cm/m 2 (0.17 to 0.20 cm/m 2 ) vs. 0.25 cm/m 2 (0.23 to 0.27 cm/m 2 )], and FFI [0.38 cm/m 2 (0.35 to 0.412 cm/m 2 ) vs. 0.47 cm/m 2 (0.44 to 0.50 cm/m 2 )] were significantly lower in patients with SO ( P <0.01). A positive correlation with SMI was seen for all parameters in the entire cohort. The strongest correlation was exhibited by QMT ( r =0.70) and QMFI ( r =0.70) in males. The area under the curve of QMT, QMFI, FMT, and FFI were 0.98 (95% confidence interval: 0.96-1), 0.95 (0.89-1), 0.85 (0.75-0.96), and 0.80 (0.68-0.93), respectively.

CONCLUSIONS

US-based assessment of sarcopenia has excellent diagnostic accuracy and correlates well with computed tomography-SMI in patients with SO. US may serve as an easy-to-use, point of care tool for assessing sarcopenia in SO with the advantage of repeated sequential assessment.

Efficacy and safety of pan-genotypic sofosbuvir and velpatasvir in patients with hepatitis C and HIV coinfection on dolutegravir-based antiretroviral therapy

Hepatitis C virus (HCV) infection is more prevalent in people living with HIV-AIDS (PLHA) and portends a poorer prognosis. Pharmacokinetic studies suggest the absence of significant interaction between velpatasvir and dolutegravir which has been recently recommended as part of preferred first-line antiretroviral therapy (ART) regimens by WHO. However, clinical data on the use of velpatasvir-based regimen in PLHA taking dolutegavir is lacking. Hence, we aimed to assess the efficacy and safety of sofosbuvir and velpatasvir (SOF + VEL) in HCV and HIV coinfected patients on dolutegravir-based ART. Forty-five consecutive PLHA with HCV coinfection on dolutegravir-based ART were prospectively enrolled. All patients were treated SOF + VEL for 12 weeks. Complete haemogram, liver and renal function tests were assessed at baseline, 4 weeks and at end of treatment. Sustained virological response (SVR) was assessed at 12 weeks after end of treatment. The majority were males (95.5%) with a mean age of 32.8 ± 12.3 years. Cirrhosis was present in 6 (13.3%) patients. All patients completed 12 weeks of therapy with SOF + VEL, but SVR could not be assessed in two patients. Forty-two (97.7%) of the remaining 43 patients attained SVR-12. SVR-12 rate was 97.7% and 93.3% by per protocol and intention to treat analysis, respectively. No grade III/IV adverse events were reported, and there was no worsening of blood counts, liver or renal function test parameters. The pan-genotypic regimen of SOF + VEL is safe and effective in PLHA with HCV coinfection who are on dolutegravir-based ART.

Efficacy, Tolerability, and Compliance of Direct Acting Antivirals in Patients with HIV and Hepatitis C Coinfection: A Real-Life Experience

Effective management of HIV and hepatitis C virus (HCV) coinfection warrants special emphasis on interactions between direct acting antivirals (DAAs) and antiretroviral therapy (ART) along with maintenance of treatment compliance. All HIV-HCV coinfected adult patients (2015-2020) were included in this real-life retrospective study. Prevalence of coinfection, proportion of coinfected patients treated, compliance rate, sustained virological response at week 12 (SVR12) after the end of therapy, and adverse events were assessed. Among 4578 HIV patients, 232 (5.1%) had HCV coinfection. Ninety-two (39.7%) were intravenous drug users. One hundred twenty-eight (55.1%) patients presented to the liver clinic. Seventy-six (32.8%) patients [mean age: 36.6 ± 10.4 years; 65 (85.5%) males; mean CD4 count: 396 ± 246 cells/mL] completed DAA therapy, whereas 52 (22.4%) patients defaulted and 75 (32.3%) were lost to follow-up. Sixty-seven (82.2%) patients had chronic hepatitis and 9 (11.8%) had compensated cirrhosis. Median (range) HCV-RNA was 5.9 × 106 IU/mL (2.4 × 105-9.9 × 105). Among 15 (19.5%) treatment experienced patients, 14 were pegylated interferon experienced and one was NS5A-inhibitor experienced. ART regimens comprised a combination of tenofovir (T), lamivudine (L), efavirenz (E), nevirapine (N), and/or zidovudine (Z) at dosage and modifications as applicable [TLE: 63 (82.9%), ZLN:11 (14.5%), and ZLE: 2 (2.6%)]. Overall, 74 (97.4%) out of 76 patients who completed DAA therapy achieved SVR12. Adverse events were minor and well-tolerated. HIV-HCV-coinfected patients demonstrate excellent SVR12 and tolerability with available DAAs, with no major adverse events.

Burden, risk factors, and outcomes of multidrug-resistant bacterial colonisation at multiple sites in patients with cirrhosis

Background & Aims

The reported burden of multidrug-resistant organism (MDRO) infections is highest in patients with cirrhosis from India. We evaluated whether colonisation at multiple barriers predisposes to such infections and poor outcomes in patients with cirrhosis.

Methods

We prospectively performed swab cultures, antimicrobial susceptibility testing (AST), and genotype testing for MDROs from various sites (rectum, nose, composite-skin, and central-line) in patients with cirrhosis (2020-2021) on admission and follow-up at a tertiary institute. We analysed clinical data, risk factors for MDROs, and patient outcomes.

Results

Of 125 patients aged 49 years, 85.6% males, 60.8% with acute-on-chronic liver failure, 99 (79.2%) were identified as 'colonisers'. MDRO-colonisation at rectum, nose, skin, or central line was observed in 72.7% (88/121), 30.0% (36/120), 14.9% (18/121), and 3.3% (4/121) patients, respectively. Patients were colonised with the following types of bacteria: extended-spectrum beta-lactamase (71/125), carbapenem-resistant Enterobacterales (67/125), MDR-Enterococcus (48/125), MDR-Acinetobacter (21/125), or methicillin-resistant Staphylococcus aureus (4/125). Multiple precipitants of acute-decompensation (odds ratio [OR]: 3.4, p = 0.042), norfloxacin prophylaxis (OR: 3.9, p = 0.008), and MDRO infection at admission (OR: 8.9, p = 0.041) were the independent predictors of colonisation. Colonisation increased the risk of infection by MDROs at admission (OR: 8.5, p = 0.017) and follow up (OR: 7.5, p <0.001). Although any-site colonisers were at greater risk of cerebral failure and poorer Child-Pugh scores, the nasal and skin colonisers were at higher risk of cerebral and circulatory failures than non-colonisers (p <0.05).Patients with more than one site colonisation (prevalence: 30%) developed multi-organ failure (p <0.05), MDRO infection (OR: 7.9, p <0.001), and poorer 30-day survival (hazard ratio: 2.0, p = 0.005).

Conclusions

A strikingly high burden of MDRO colonisation among patients with cirrhosis in India necessitates urgent control measures. Multiple-site colonisation increases the risk of MDR-infections, multi-organ failure, and mortality in patients with cirrhosis.

Impact and Implications

Infections by bacteria resistant to multiple antibiotics are an emerging cause of death in cirrhosis. We showed that ∼70-80% of critically ill hospitalised patients with cirrhosis carry such bacteria with the highest rate in the rectum, nose, skin, and central line port. Carbapenem-resistant and vancomycin-resistant bacteria were amongst the most common colonising bacteria. The presence of these bacteria at multiple sites increased the risk of multidrug-resistant infections, multiple organ failures, and death in patients with cirrhosis.

Simple bedside tests of muscle strength and function correlate with computed tomography-skeletal muscle index for assessment of sarcopenia in cirrhosis

BACKGROUND

Sarcopenia assessment can be done by skeletal muscle index (SMI) or bedside tests such as handgrip strength (HGS) and gait speed (GS).

GOALS

This study evaluated the correlations of HGS and GS with SMI, health-related quality of life (HRQOL) and cognition and assessed them as predictors of mortality.

STUDY

As many as 116 outpatients with cirrhosis were included in this prospective cohort study. Assessment for sarcopenia was done by SMI, HGS and GS. HRQOL was assessed using the chronic liver disease questionnaire (CLDQ) and fatigue severity scale (FSS). Cognition was assessed by mini-mental state examination (MMSE). Correlations of HGS and GS with SMI, HRQOL and cognition were analyzed. Area under the curve (AUCs) were calculated to compare them as predictors of mortality.

RESULTS

Alcoholic liver disease (47.4%) was the commonest etiology of cirrhosis followed by hepatitis C (12.9%). Sarcopenia was diagnosed in 64 (55.2%) patients. A strong correlation was seen between SMI and HGS (ρ = 0.78) and GS (ρ = 0.65). AUCs of GS (0.91 (95% confidence interval [CI], 0.85-0.96) was maximum, followed by HGS (95% CI, 0.86 [0.78-0.93] and SMI [95% CI, 0.8 0.71-0.88]) in predicting mortality (p > 0.05). CLDQ (3.2 vs. 5.6, p < 0.01) and MMSE scores (24.3 vs. 26.3, p < 0.01) were lower, whereas FSS score (5.7 vs. 3.1, p < 0.01) was higher in patients with sarcopenia. CLDQ (ρ = 0.83) and MMSE (ρ = 0.73) showed the strongest correlation with HGS, whereas FSS correlated well (ρ = 0.77) with GS.

CONCLUSIONS

Bedside tests of muscle strength and function, including HGS and GS, correlate strongly with SMI for sarcopenia assessment and prediction of mortality in patients with cirrhosis.

Combination of terlipressin and noradrenaline versus terlipressin in hepatorenal syndrome with early non-response to terlipressin infusion: A randomized trial

BACKGROUND

Terlipressin and noradrenaline are effective in the management of hepatorenal syndrome (HRS). There are no reports on the combination of these vasoconstrictors in type-1 HRS.

AIM

To evaluate terlipressin with or without noradrenaline in type-1 HRS not responding to terlipressin at 48 hours.

METHODS

Sixty patients were randomized to receive either terlipressin (group A; n = 30) or a combination of terlipressin and noradrenaline infusion (group B; n = 30). In group A, terlipressin infusion was started at 2 mg/day and increased by 1 mg/day (maximum 12 mg/day). In group B, terlipressin was given at a constant dose of 2 mg/day. Noradrenaline infusion was started at 0.5 mg/h at baseline and increased to 3 mg/h in a stepwise manner. The primary outcome was treatment response at 15 days. Secondary outcomes were 30-day survival, cost-benefit analysis and adverse events.

RESULTS

There was no significant difference in the response rate between the groups (50% vs. 76.7%, p = 0.06) and 30-day survival was similar (36.7% vs. 53.3%, p = 0.13). Treatment was more expensive in group A (USD 750 vs. 350, p < 0.001). Adverse events were more frequent in group A (36.7% vs. 13.3%, p < 0.05).

CONCLUSIONS

The combination of noradrenaline and terlipressin infusion results in a non-significantly higher rate of HRS resolution with significantly fewer adverse effects in HRS patients who do not respond to terlipressin within 48 hours.

Special Population: Lean Nonalcoholic Fatty Liver Disease

Nonalcoholic fatty liver disease (NAFLD) is strongly associated with obesity but around 10% to 20% of patients with NAFLD have normal body mass index, a condition referred to as lean or nonobese NAFLD. Although lean patients more often have milder liver disease, a proportion may nonetheless develop steatohepatitis and advanced liver fibrosis. Both genetic and environmental factors contribute to the development of NAFLD. Noninvasive tests have similarly good accuracy as initial assessments for lean NAFLD. Future studies should determine the most appropriate treatment in this special population.

INASL-SAASL Consensus Statements on NAFLD Name Change to MAFLD

There is an ongoing debate on the change of terminology of non-alcoholic fatty liver disease (NAFLD) to metabolic associated fatty liver disease (MAFLD). Experts from the Indian National Association for Study of the Liver (INASL) and the South Asian Association for Study of the Liver (SAASL) involved in diagnosing, managing, and preventing NAFLD met in March 2022 to deliberate if the name change from NAFLD to MAFLD is appropriate, as proposed by a group of experts who published a "consensus" statement in 2020. Proponents of name change to MAFLD opined that NAFLD does not reflect current knowledge, and the term MAFLD was suggested as a more appropriate overarching term. However, this "consensus" group which proposed the name change to MAFLD did not represent the views and opinions of gastroenterologists and hepatologists, as well as perceptions of patients across the globe, given the fact that change of nomenclature for any disease entity is bound to have multidimensional impact on all aspects of patient care. This statement is the culmination of the participants' combined efforts who presented recommendations on specific issues concerning the proposed name change. The recommendations were then circulated to all the core group members and updated based on a systematic literature search. Finally, all the members voted on them using the nominal voting technique as per the standard guidelines. The quality of evidence was adapted from the Grades of Recommendation, Assessment, Development and Evaluation system.

Machine learning can guide suitability of consultation and patient referral through telemedicine for hepatobiliary diseases

BACKGROUND AND AIM

Telemedicine is an evolving tool to provide health-care services. We evaluated the suitability of telemedicine to deliver effective consultation for hepatobiliary disorders.

METHODS

In this prospective study spanning over a year, we interviewed hepatologists delivering the teleconsultations through a pre-validated questionnaire. A consult was deemed suitable based on the physician's judgment in the absence of unplanned hospitalization. We evaluated factors determining the suitability through inferential statistics and machine learning models, namely, extreme gradient boosting (XGB) and decision tree (DT).

RESULTS

Of 1118 consultations, 917 (82.0%) were deemed suitable. On univariable analysis, patients with skilled occupation, higher education, out-of-pocket expenses, and diseases such as chronic hepatitis B, C, and non-alcoholic fatty liver disease (NAFLD) without cirrhosis were associated with suitability (P < 0.05). Patients with cirrhosis (compensated or decompensated), acute-on-chronic liver failure (ACLF), and biliary obstruction were likely unsuitable (P < 0.05). XGB and DT models predicted suitability with an area under the receiver operating curve of 0.808 and 0.780, respectively. DT demonstrated that compensated cirrhosis with higher education or skilled occupation with age < 55 years had 78% chance of suitability whereas hepatocellular carcinoma, decompensated cirrhosis, and ACLF patients were unsuitable with a 60-95% probability. In non-cirrhotic liver diseases, hepatitis B, C, and NAFLD were suitable, with a probability of 89.7%. Biliary obstruction and previous failure of teleconsultation were unsuitable, with a probability of 70%. Non-cirrhotic portal fibrosis, dyspepsia, and dysphagia not requiring intervention were suitable (probability: 88%).

CONCLUSION

A simple decision tree can guide the referral of unsuitable and the management of suitable patients with hepatobiliary diseases through telemedicine.

Spectrum of Autoimmune Liver Disease and Real-World Treatment Experience from a Tertiary Care Hospital

Background and aims

Autoimmune liver disease (AILD) comprises of autoimmune hepatitis (AIH), primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) with a spectrum of overlap amongst the three. We analyzed the spectrum and treatment outcomes of patients with AILD presenting to a tertiary care center in India.

Methods

A retrospective analysis of AILD patients from June 2008 to April 2021 was performed. The diagnosis was based on clinical, biochemical, imaging, serological, and histological characteristics. Eligible patients received treatment depending on the disease stage. Biochemical response to treatment was defined as normalization of AST, ALT, bilirubin, and immunoglobulin G levels at 6 months in AIH, normalization of total bilirubin and/or albumin at 1 year in PBC and decrease in alkaline phosphatase (ALP) levels by 40% in PSC.

Results

Two hundred seventy-five patients were analyzed. AIH (58.54%) was most common, followed by an overlap of AIH-PBC (24%) and AIH-PSC (6.54%), PSC (6.18%), and PBC (4.72%). Most patients presented in 3rd or 4th decade, except PBC which occurred predominantly in 5th decade. The majority of patients were females (72.72%). Jaundice was the most common presentation seen in 60% of patients. Cirrhosis was present in 57.47% of patients. Patients with overlap had more pruritus (54.76 vs 6.83%), fatigue (63.1% vs 49.7%), hepatomegaly (52.4% vs 25.5%), and higher ALP (80.9% vs 37.7%) than patients with AIH alone. Acute presentation was seen in 33 patients (13.5%) with most having AIH flare. Five patients had acute liver failure (ALF) and 9 had acute-on-chronic liver failure (ACLF). ALF was associated with 80% mortality while 55.56% of patients with ACLF had a complete biochemical response to immunosuppression. Among patients with AIH and/or overlap who received immunosuppression, a complete biochemical response to immunosuppression was seen in 60.69% of patients. High ALT (OR 1.001 [1.000-1.003], P = 0.034), high albumin (OR 1.91 [1.05-3.48], P = 0.034) and low fibrosis on biopsy (OR 0.54 [0.33-0.91], P = 0.020) predicted complete response.

Conclusion

AIH is the most common AILD followed by overlap syndromes, PSC and PBC in our cohort. Biochemical response to immunosuppression is seen in 60% of patients with AIH & low fibrosis score on histopathology predicts a complete response.

Indian National Association for Study of the Liver (INASL) Guidance Paper on Nomenclature, Diagnosis and Treatment of Nonalcoholic Fatty Liver Disease (NAFLD)

Nonalcoholic fatty liver disease (NAFLD) is a major cause of chronic liver disease globally and in India. The already high burden of NAFLD in India is expected to further increase in the future in parallel with the ongoing epidemics of obesity and type 2 diabetes mellitus. Given the high prevalence of NAFLD in the community, it is crucial to identify those at risk of progressive liver disease to streamline referral and guide proper management. Existing guidelines on NAFLD by various international societies fail to capture the entire landscape of NAFLD in India and are often difficult to incorporate in clinical practice due to fundamental differences in sociocultural aspects and health infrastructure available in India. A lot of progress has been made in the field of NAFLD in the 7 years since the initial position paper by the Indian National Association for the Study of Liver on NAFLD in 2015. Further, the ongoing debate on the nomenclature of NAFLD is creating undue confusion among clinical practitioners. The ensuing comprehensive review provides consensus-based, guidance statements on the nomenclature, diagnosis, and treatment of NAFLD that are practically implementable in the Indian setting.

Antibody Response and Safety of ChAdOx1-nCOV (Covishield) in Patients with Cirrhosis: A Cross-Sectional, Observational Study

INTRODUCTION

Patients with cirrhosis have a higher risk of severe COVID-19 and mortality and are high-priority patients for vaccination. However, cirrhotics were excluded from the phase 2/3 vaccine trials. Hence, we aimed to assess the antibody response and safety of Covishield (ChAdOx1nCoV-19) among patients with cirrhosis.

METHODS

Patients who attended the tele-hepatology services at our institute from March 2020 to June 2021 and diagnosed with cirrhosis as per their medical records were telephonically interviewed in July 2021 using a pre-specified questionnaire. Patients who had completed 2 doses of ChAdOx1-nCOV (with the 2^nd dose administered at least 2 weeks back) and without history of documented COVID-19 infection (pre- or post-vaccination) were tested for antibodies against the spike protein. Seropositive patients were divided into high, moderate, and low antibody responses based on the signal/cut-off.

RESULTS

We interviewed 784 patients with cirrhosis. At least 1 dose of ChAdOx1-nCOV was received by 231 patients among whom 134 (58%) had received 2 doses. Documented COVID-19 was reported in 3.9% patients who received at least 1 dose of ChAdOx1-nCOV including breakthrough infections in 3.7% patients vaccinated with 2 doses. Local and systemic adverse events were reported by 42% and 22.1% patients. None developed anaphylaxis, acute decompensation, acute-on-chronic liver failure, or other serious adverse events requiring hospitalization. Seroconversion was documented in 81 (92%) out of 88 patients. No difference was observed in level of antibody response between patients with compensated and decompensated cirrhosis (p = 0.12).

CONCLUSION

Our preliminary data suggest that ChAdOx1-nCOV is safe with high seroconversion rates in patients with cirrhosis.

Home-based intensive nutrition therapy improves frailty and sarcopenia in patients with decompensated cirrhosis: A randomized clinical trial

BACKGROUND AND AIM

The majority of patients with decompensated cirrhosis suffer from malnutrition, a potentially modifiable contributor to frailty and sarcopenia. The present study investigated the impact of a 6-month dietician-supported home-based intensive nutrition therapy (HINT) intervention on objective frailty and sarcopenia metrics in patients with decompensated cirrhosis.

METHODS

One hundred adult patients with decompensated cirrhosis, frailty, and sarcopenia at baseline were randomized 1:1 to receive standard medical therapy (SMT) plus HINT (intervention) versus SMT (control) alone. The primary outcome was an improvement in frailty as measured by the liver frailty index (LFI). Secondary outcome measures included sarcopenia metrics, liver disease severity scores, hospitalization, and death.

RESULTS

The LFI improved more in the intervention arm as compared with controls (0.8 vs 0.4; P < 0.001). Baseline and end-of-study skeletal muscle index (SMI) was available in a subset of 32 male patients, with greater improvements seen in the intervention arm compared with controls (6.36 vs 0.80; P = 0.02). Patients in the intervention arm had less hospitalizations over the 6-month follow-up (19 [38%] vs 29 [58%]; P = 0.04). On subgroup analysis, in the 64% of patients who were adherent to calorie and protein intake targets at 6 months, significant improvement was seen in liver disease severity scores and survival (P < 0.05).

CONCLUSION

In patients with decompensated cirrhosis, frailty, and sarcopenia, a 6-month dietitian-supported home-based intensive outpatient nutrition therapy was associated with statistically and clinically relevant improvement in frailty. The subgroup of adherent patients showed improvement in their liver disease scores and reduction in mortality. These findings support the key role of food as medicine in the management of cirrhosis.

Association of Heparin-Like Effect, Factor VII/XIII Deficiency and Fibrinolysis with Rebleeding Risk in Cirrhosis with Acute Variceal Bleeding

BACKGROUND

Hyperfibrinolysis and coagulation dysfunction may occur in cirrhotic patients with acute variceal bleed (AVB) despite successful endotherapy.

AIMS

To prospectively study the association of endogenous heparinoids and coagulation dysfunction with variceal rebleeding and outcome in cirrhosis.

METHODS

Consecutive patients were assessed with conventional coagulation tests, SONOCLOT™ [(global(gb) and heparinase(h) treated] and factors VII, VIII, XIII, X, tissue plasminogen activator, and plasminogen activator inhibitor ELISA assays in a university hospital. Heparin-like-effect (HLE) was defined as ≥ 20% difference in paired gb/h-SONOCLOT™ traces for activated clotting time (ACT).

RESULTS

Of 143 patients screened, 90 (46.4 ± 11.7 years, males 82.2%, ethanol-related 58.8%) were recruited, who bled from esophageal varices (81,90.0%), gastric varices (6,6.6%), or esophageal varices with portal hypertensive gastropathy (3,3.3%). Twenty (21.7%) had early rebleeding, mainly post-variceal ligation ulcer related (70%). Patients who rebled had low Factor XIII [1.6 (1.2-2.1) vs 2.4 ng/ml (2.0-2.8) P = 0.035] and Factor VII (94.1 ± 46.9 vs. 124.0 ± 50.4, P = 0.023). On receiver operating curve analysis, the gbACT > 252 s (sensitivity 86.8%, specificity 76.9%, P < 0.001), hACT > 215 s (sensitivity 71.1%, specificity 70.3%, P < 0.001), and HLE > 50% (sensitivity 69.5%, specificity 70.3%, P = 0.006) predicted rebleeding. Baseline Factor VIII (HR 1.26; 95% CI 1.17-1.34, P < 0.001), low factor VII (HR 0.89; 95% CI 0.76-0.98, P = 0.035), and lysis (HR 1.25, 95% CI 1.17-1.33, P < 0.001) predicted mortality. Endogenous heparinoids at baseline predicted sepsis (HR 1.8; 95% CI 1.4-6.5; P = 0.022), rebleeding events (HR 1.2; 95% CI 1.1-6.3; P = 0.030), and mortality (HR 1.1; 95% CI 1.0-4.6; P = 0.030).

CONCLUSIONS

Hyperfibrinolysis, Factor VII/XIII deficiency, and HLE are associated with rebleeding after AVB. Trial Registration NCT04111120 available from https://clinicaltrials.gov/ct2/show/NCT04111120 .

Spring and latch dynamics can act as control pathways in ultrafast systems

Ultrafast movements propelled by springs and released by latches are thought limited to energetic adjustments prior to movement, and seemingly cannot adjust once movement begins. Even so, across the tree of life, ultrafast organisms navigate dynamic environments and generate a range of movements, suggesting unrecognized capabilities for control. We develop a framework of control pathways leveraging the non-linear dynamics of spring-propelled, latch-released systems. We analytically model spring dynamics and develop reduced-parameter models of latch dynamics to quantify how they can be tuned internally or through changing external environments. Using Lagrangian mechanics, we test feedforward and feedback control implementation via spring and latch dynamics. We establish through empirically-informed modeling that ultrafast movement can be controllably varied during latch release and spring propulsion. A deeper understanding of the interconnection between multiple control pathways, and the tunability of each control pathway, in ultrafast biomechanical systems presented here has the potential to expand the capabilities of synthetic ultra-fast systems and provides a new framework to understand the behaviors of fast organisms subject to perturbations and environmental non-idealities.

Quantitative liver SPECT/CT is a novel tool to assess liver function, prognosis, and response to treatment in cirrhosis

Background

Functional liver reserve is an important determinant of survival in cirrhosis. The traditional indocyanine green test (ICG) is cumbersome. Hence, we developed and validated a novel liver imaging, a hybrid of SPECT and CT (Q-SPECT/CT), for evaluating disease severity, outcomes, and response to treatment in decompensated cirrhosis (DC).

Methods

We recruited a cohort of DC patients at a tertiary institute between 2016-2019. First, we standardized the Q-SPECT/CT across a predefined range of volumes through phantom experiments. Then we performed clinical and laboratory evaluations, ICG test (retention at 15 min), and Q-SPECT/CT at baseline and 12 months of granulocyte colony-stimulating factor (G-CSF) and standard medical treatment (SMT).

Results

In 109 DC patients, 87.1% males, aged 51 ± 10 years, MELD: 14 (7-21), the percent quantitative liver uptake (%QLU) on Q-SPECT/CT exhibited a strong correlation with CTP (r = -0.728, p < 0.001), MELD (r = -0.743; p < 0.001) and ICG-R-15 (r = -0.720, p < 0.001) at baseline. %QLU had the maximum discrimination (AUC: 0.890-0.920), sensitivity (88.9-90.3%), specificity (81.2-90.7%), and accuracy (85.8-89.4%) than liver volumes on Q-SPECT/CT or ICG test for classifying patients in CTP/MELD based prognostic categories. A significant increase in %QLU (26.09 ± 10.06 to 31.2 ± 12.19, p = 0.001) and improvement in CTP/MELD correlated with better survival of G-CSF treated DC patients (p < 0.05). SMT did not show any improvement in Q-SPECT/CT or clinical severity scores (p > 0.05). %QLU > 25 (adj.H.R.: 0.234, p = 0.003) and G-CSF treatment (adj.H.R.: 0.414, p = 0.009) were independent predictors of better 12-months survival in DC.

Conclusion

Q-SPECT/CT (%QLU) is a novel non-invasive, diagnostic, prognostic, and theragnostic marker of liver reserve and its functions in cirrhosis patients.

Indian patients with human immunodeficiency virus infection have high prevalence but mild severity of non-alcoholic fatty liver disease

BACKGROUND AND AIMS

Antiretroviral therapy (ART) has substantially decreased AIDS-related mortality. Non-AIDS related diseases like chronic liver disease are becoming more frequent in people living with HIV-AIDS (PLHA). Non-alcoholic fatty live disease (NAFLD) is a common etiology of liver disease in the general population. Our aim was to analyse the prevalence and risk factors of NAFLD in Indian PLHA.

METHODS

One hundred consecutive adults (age:36.89 ± 10.4 years, males:65%) with HIV infection were prospectively enrolled. Patients with significant alcohol intake, Hepatitis B or Cco-infection, other liver disease, malignancy or HIV stage IV were excluded. Hepatic steatosis was assessed using hepatobiliary ultrasoundand controlled attenuation parameter (CAP). Fibrosis was assessed non-invasively using FIB-4, NAFLD fibrosis score (NFS) and liver stiffness measurement (LSM). Metabolic and HIV-related risk factors were compared between PLHA with and without NAFLD.

RESULTS

Prevalence of NAFLD using CAP was 60%. Among patients with NAFLD, 27 (45%) were lean. Majority had mild-moderate steatosis. Advanced fibrosis was present in 1 (1.67%) and 4 (6.67%) patients using NFS and LSM and none using FIB-4. PLHA with NAFLD were more likely to be overweight or obese (OR = 4.21,p = 0.002) with a higher proportion of abdominal obesity (OR:25.26,p = 0.001). Other metabolic comorbidities, duration of HIV infection, duration and type of ART, CD4-count or HIV-stagewere not significantly different among PLHA with or without NAFLD.

CONCLUSION

Prevalence of NAFLD among Indian PLHA is high although most have mild disease. Almost half of these patients are lean. HIV-related factors do not impact the risk of NAFLD.

Lysosomal Acid Lipase Activity in Non-alcoholic Fatty Liver Disease as a Novel Diagnostic and Therapeutic Target: A Systematic Literature Review of Current Evidence and Future Directions

Background and aim

Non-alcoholic fatty liver disease (NAFLD) presents with the accumulation of excessive intra-hepatic fat without significant alcohol intake. Multifactorial pathogenesis is reported to be involved. Reduced lysosomal acid lipase (LAL) activity is suggested as one of the novel-involved pathogenic mechanisms. This review summarizes the available evidence on the role of LAL activity in NAFLD pathogenesis.

Methods

Four databases namely, PubMed/Medline, Science direct, Cochrane Library, and Google scholar were searched to identify relevant observational records evaluating the role of LAL activity in the pathogenesis of NAFLD. All studies were assessed for their quality by using Newcastle-Ottawa Scale or The Joanna Briggs Institute Critical Appraisal tools for cohort and cross-sectional studies, respectively. The estimates of LAL activity and other clinical outcomes were expressed as mean (SD) and number (%) as presented in the primary studies.

Results

A total of nine good quality studies with 1711 patients with NAFLD and 877 controls from different groups (healthy volunteers, alcoholics, cryptogenic cirrhosis, and HCV-positive) were included. From the NAFLD group, 59.55% were males and the overall mean age ranged between the studies from 12.6 ± 8.5 months in pediatrics to 58.90 ± 13.82 years in adults. In the NAFLD group, the LAL activity varied from 0.53 ± 0.08 to 1.3 ± 0.70 (nmol/spot/hr) between the studies which was less than all control groups except cryptogenic cirrhosis patients (0.5 ± 0.15 nmol/spot/hr). Of the other outcomes of interest, ALT, AST, total cholesterol, triglyceride, and LDL cholesterol were found elevated in NAFLD patients than in controls.

Conclusion

The current evidence suggests a potential correlation of reduced LAL activity with NAFLD pathogenesis according to its severity. Large-scale studies are recommended, more importantly in patients with NAFLD having no metabolic or genetic involvement. Further LAL can act as a new non-invasive diagnostic biomarker to identify that specific NAFLD subgroup.

The effects of systemic immunomodulatory treatments on COVID-19 outcomes in patients with atopic dermatitis: Results from the global SECURE-AD registry

BACKGROUND

Limited data are available on the effects of systemic immunomodulatory treatments on COVID-19 outcomes in patients with atopic dermatitis (AD).

OBJECTIVE

To investigate COVID-19 outcomes in patients with AD treated with or without systemic immunomodulatory treatments, using a global registry platform.

METHODS

Clinicians were encouraged to report cases of COVID-19 in their patients with AD in the Surveillance Epidemiology of Coronavirus Under Research Exclusion for Atopic Dermatitis (SECURE-AD) registry. Data entered from 1 April 2020 to 31 October 2021 were analysed using multivariable logistic regression. The primary outcome was hospitalization from COVID-19, according to AD treatment groups.

RESULTS

442 AD patients (mean age 35.9 years, 51.8% male) from 27 countries with strongly suspected or confirmed COVID-19 were included in analyses. 428 (96.8%) patients were treated with a single systemic therapy (n = 297 [67.2%]) or topical therapy only (n = 131 [29.6%]). Most patients treated with systemic therapies received dupilumab (n = 216). Fourteen patients (3.2%) received a combination of systemic therapies. Twenty-six patients (5.9%) were hospitalized. No deaths were reported. Patients treated with topical treatments had significantly higher odds of hospitalization, compared with those treated with dupilumab monotherapy (odds ratio (OR) 4.65 [95%CI 1.71-14.78]), including after adjustment for confounding variables (adjusted OR (aOR) 4.99 [95%CI 1.4-20.84]). Combination systemic therapy which did not include systemic corticosteroids was associated with increased odds of hospitalization, compared with single agent non-steroidal immunosuppressive systemic treatment (OR 8.09 [95%CI 0.4-59.96], aOR 37.57 [95%CI 1.05-871.11]). Hospitalization was most likely in patients treated with combination systemic therapy which included systemic corticosteroids (OR 40.43 [95%CI 8.16-207.49], aOR 45.75 [95%CI 4.54-616.22]).

CONCLUSIONS

Overall, the risk of COVID-19 complications appears low in patients with AD, even when treated with systemic immunomodulatory agents. Dupilumab monotherapy was associated with lower hospitalization than other therapies. Combination systemic treatment, particularly combinations including systemic corticosteroids, was associated with the highest risk of severe COVID-19.

IgG4-Related Sclerosing Cholangitis with Cholecystitis Mimicking Cholangiocarcinoma: A Case Report

IgG4-related diseases are rare multisystem disorders involving salivary glands, retroperitoneum, pancreas, biliary tract, and liver. Isolated biliary strictures and gall bladder involvement are rare in such patients, and presentation with cholangitis and weight loss can misguide the diagnosis toward malignancy. Here, we report an interesting case of IgG4-related biliary stricture with gall bladder involvement, presented with cholangitis and weight loss. The initial symptoms and imaging were guided toward the malignant possibilities of cholangiocarcinoma and pancreatic carcinoma. However, endosonography, serology, and histopathology clinched the diagnosis of IgG4-related disease. The patient was managed without any biliary intervention and with antibiotics, steroids, and steroid-sparing agents. There was a relapse of disease during the steroids taper that improved after hiking its doses. The disease responded with medical management on follow-up. We demonstrated the effectiveness of steroid-sparing agents to treat IgG4-related diseases, especially to avert the steroid-related adverse effects. This case highlights the possible mislead for the diagnosis and delayed management of IgG4 disease due to shared clinical features with hepatobiliary malignancies and the effectiveness of noninvasive measures of management.

Improvement of chronic HCV infection-related depression, anxiety, and neurocognitive performance in persons achieving SVR-12: A real-world cohort study

Chronic hepatitis C virus (HCV) infection is associated with neuropsychiatric changes. Also, patients with cirrhosis may develop overt or minimal hepatic encephalopathy. Sustained virological response (SVR) with direct-acting antiviral agents (DAAs) may improve the neuropsychiatric manifestations and quality of life (QoL). Consecutive patients (with and without cirrhosis, all genders and aged 18-65 years) with hepatitis C were assessed at enrolment and at 12 weeks after therapy completion for mood (Beck's Depression Inventory [BDI]), anxiety (generalized anxiety disorder [GAD-7]), QoL (SF-36 ver.2) and computer-based tests for number connection (NCT), visual memory, Stroop test and reaction times. We recruited 385 viraemic chronic HCV patients (76.1% male, 21.0% cirrhotic, mean age 39.4 ± 14.2 years, 59.3% genotype 3, mean HCV RNA load 5.8 log). Overall SVR-12 rates were 90.6%, with cure rates 87.6% and 91.4% in patients with and without cirrhosis, respectively. Patients who achieved SVR-12 had mean percentage reduction in BDI (11.3%, p = .000), GAD (8.6%, p = .001) and Stroop test (58.4%, p = .001), with improved NCT (1.7%, p = .001), visual memory (13.7%, p = .001) and digit span (23.8%, p = .002). On multivariate logistic regression, adherence (OR, 17.5 [95% CI 2.80-110.50], p = .000), high ALT (OR 1.02 [95% CI 1.00-1.05]), and BDI score (OR 1.73 [95% CI 1.42-3.26] p = .039) predicted cure. SVR-12 was associated with improved visual memory ≥5.5 (AUC-0.708; sensitivity 62.5%, specificity 63%, p = .000) and % correct Stroop test responses >26.6% (AUC-0.918, sensitivity 94.4% specificity 80.4%, p = .000). In conclusion, given the cumulative evidence of the safety of DAAs and efficacy of improving cognitive and neuropsychological and quality-of-life outcomes irrespective of age and gender, as shown in our study, future recommendations should focus on integrated universal HCV care to enable HCV elimination.

Multiple cycles of granulocyte colony-stimulating factor in decompensated cirrhosis: a double-blind RCT

BACKGROUND

Liver transplant, the definitive treatment of decompensated cirrhosis (DC), is constrained by donor shortage and long-term complications. Granulocyte colony-stimulating factor (G-CSF) has been explored as an alternative option in open-label studies. This double-blind, randomized, placebo-controlled trial was designed to elucidate the efficacy of G-CSF in DC.

METHODS

Seventy patients were randomized to either G-CSF plus standard medical therapy (group A, n = 35) or placebo plus standard medical therapy (group B, n = 35). Primary outcome was 12-month overall survival in patients who received at least one cycle of intervention. Secondary outcomes were mobilization of CD34+ cells at day 6, improvement in Child-Turcotte-Pugh (CTP), and model for end-stage liver disease (MELD), liver stiffness measurement, quality of life, nutrition, hepatic decompensation, infection, hospitalization, and acute kidney injury.

RESULTS

Survival in group A was higher than that in Group B although the difference was not statistically significant (87.9% vs 66.7%; p = 0.053). CD34+ cells at day 6 were significantly higher in group A as compared to baseline (p < 0.001). Ascites control (p = 0.03) and CTP score improvement (p = 0.02) were better in group A at 12-months. Encephalopathy episodes (p = 0.005), infections (p = 0.005) were fewer in group A than group B at 12 months. Other secondary outcomes did not improve post-therapy. There were no treatment-related discontinuations or severe adverse events.

CONCLUSIONS

G-CSF therapy is safe. The improvement in survival at 12 months is not statistically significant. Better control of ascites, improvement of CTP score, fewer encephalopathy episodes and decreased rate of infections were observed with G-CSF therapy (NCT03911037). Trials Registration NCT03911037.

Invasive Pulmonary Aspergillosis and Tuberculosis Complicated by Hemophagocytic Lymphohistiocytosis - Sequelae of COVID-19 in a Liver Transplant Recipient

Liver transplant recipients are at an increased risk of opportunistic infections due to the use of immunosuppression. Coronavirus disease of 2019 (COVID-19) increases the risk of these infections further due to associated immune dysfunction and the use of high-dose steroids. We present a case of a liver transplant recipient who developed disseminated tuberculosis and invasive pulmonary aspergillosis complicated by acquired hemophagocytic lymphohistiocytosis after recovering from severe COVID-19.

High Prevalence of Hormonal Changes and Hepatic Osteodystrophy in Frail Patients with Cirrhosis-An Observational Study

BACKGROUND/AIM

Hormonal changes and hepatic osteodystrophy are less often studied complications of cirrhosis. This study describes the variance in hormones and osteodystrophy between Frail and Not frail patients with cirrhosis.

METHODS

116 outpatients with cirrhosis were prospectively enrolled in this study. Frailty assessment was done using Liver Frailty Index (LFI). Sociodemographic assessment, anthropometry, nutritional assessment, hormone profile, and dual-energy X-ray absorptiometry scan were done in all patients.

RESULTS

116 patients, predominantly males (100 (86.2%) with mean age of 50.16 years (95% CI, 48.43-51.89) were included. Malnutrition was more common in Frail group as compared to Not frail group. Subjective global assessment (SGA) class-B patients were significantly more in Frail group (37 (74%) vs 3 (4.5%), P = 0.001). The prevalence of lower parathyroid hormone (PTH) (14 (28%) vs 2 (3%)), testosterone (33 (66%) vs 15 (22.7%)), vitamin D3 (44 (88%) vs 39 (59.1%)), and cortisol (37 (74%) vs 37 (56.1) levels was higher in Frail group (P < 0.05). The number of patients diagnosed with osteodystrophy (34 (68%) vs 21 (31.8%), P = 0.001) was significantly higher in Frail group. The marker of osteoclastic activity, β-cross laps, was significantly elevated in the Frail group both in males (736 (655-818) vs 380 (329-432), P = 0.001) and (females 619 (479-758) vs 313 (83-543), P = 0.02). Bone mineral density (BMD) at lumbar spine (LS) and neck of femur (NF) had significant correlation with LFI (ρ = 0.60, P = 0.001 for LS and ρ = 0.59, P = 0.001 for NF), serum testosterone (ρ = 0.58, P = 0.001 for LS and ρ = 0.53, P = 0.001 for NF), β-cross laps (ρ = 0.38, P = 0.001for LS and ρ = 0.35, P = 0.000 for NF), vitamin D3 (ρ = 0.23, P = 0.04 for LS and ρ = 0.25, P = 0.01 for NF), PTH (ρ = 0.52, P = 0.001 for LS and ρ = 0.48. P = 0.001 for NF), and cortisol (ρ = 0.50, P = 0.001 for LS and ρ = 0.45, P = 0.001 for NF) levels.

CONCLUSION

This is the first study that highlights the high prevalence of hormonal changes and hepatic osteodystrophy in frail patients with cirrhosis and opens a new dimension for research and target of therapy in this field.
