RESUMO

INTRODUCTION: The prevalence, health and socioeconomic burden of metabolic dysfunction-associated fatty liver disease (MAFLD) is growing, increasing the need for novel evidence-based lifestyle approaches. Lifestyle is the cornerstone for MAFLD management and co-existing cardiometabolic dysfunction. The aim of this review was to evaluate the evidence for lifestyle management of MAFLD, with a specific lens on 24-hour integrated behaviour and provide practical recommendations for implementation of the evidence. RESULTS: Weight loss ≥ 7-10% is central to lifestyle management; however, liver and cardiometabolic benefits are attainable with improved diet quality and exercise even without weight loss. Lifestyle intervention for MAFLD should consider an integrated '24-h' approach that is cognisant of diet, physical activity/exercise, sedentary behavior, smoking, alcohol intake and sleep. Dietary management emphasises energy deficit and improved diet quality, especially the Mediterranean diet, although sociocultural adaptations to meet preferences should be considered. Increasing physical activity and reducing sedentary behavior can prevent MAFLD, with strongest evidence in MAFLD supporting regular structured moderate-vigorous aerobic exercise for 150-240 min/week. Resistance training in addition to aerobic exercise should be considered and prioritised for those who are losing body mass via diet and/or pharmacological approaches and those with sarcopenia, to minimise bone and lean mass loss. Limited evidence suggests that sleep is important for MAFLD prevention. Emerging novel approaches to diet and exercise may address some of the key barriers to behaviour change (e.g. lack of time, access to resources and social support). FUTURE DIRECTIONS: Large-scale multidisciplinary trials in people with MAFLD with long-term follow-up, that can be scaled up into mainstream healthcare, are required. Future management guidelines should consider the heterogeneity of MAFLD and specialised models of care that coordinate the health workforce to manage the increased and growing MAFLD population.

RESUMO

Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) is a promising technique for treating small left hepatic lesions, particularly where ablation via percutaneous route is deemed to be technically difficult. Herein, we report a case of a 64-year-old cirrhotic patient with caudate lobe hepatocellular carcinoma (HCC) who underwent EUS-RFA, resulting in complete ablation of the tumor and also review the related literature.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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: NCT04238416 (clinicaltrials.gov).

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Erythropoietic protoporphyria (EPP) presents with nonblistering photosensitivity. Hepatobiliary manifestations are seen in around 5% cases and include cholelithiasis, elevations in liver enzymes, progressive jaundice, and end-stage liver disease. The diagnosis is suspected based on clinical features and elevated erythrocyte metal-free protoporphyrin and confirmed by genetic analysis showing loss-of-function mutations in the ferrochelatase (FECH) gene. We present an adolescent boy who presented with jaundice and photosensitivity with the liver biopsy showing deposition of brown pigments within the canaliculi and hepatocytes. This pigment showed Maltese cross birefringence on polarizing microscopy and Medusa-head appearance on electron microscopy. Genetic analysis revealed loss-of-function mutations in FECH. Introduction of EPP is an inborn error of heme biosynthesis caused by mutations in FECH with a prevalence of 1:75,000 to 1:200,000. We present a case of a 16-year-old adolescent boy with photosensitivity, abdominal pain, and jaundice with protoporphyrin deposition in the liver who was ultimately diagnosed with EPP based on genetic analysis.

RESUMO

Background: Triple negative breast carcinoma (TNBC) has the highest mortality among all the breast carcinoma subtypes, but paradoxically, it shows the best response to neoadjuvant chemotherapy (NACT). Tumor infiltrating lymphocytes (TIL) density has been shown to have prognostic significance in TNBC. However, there are limited data on TIL subpopulation and their association with response to NACT in TNBC. Materials and Methods: The study included 80 consecutive patients with TNBC prospectively diagnosed for two and half years, who underwent tru-cut biopsy before NACT, followed by subsequent definite surgical procedures. Global TIL profile and immunohistochemistry (IHC) analysis of CD3, CD4, CD8, CD20, and CD56 were done on all baseline tru-cut biopsies and post-NACT surgical specimens. Results: Almost half the patients were postmenopausal with a mean age of 45.89 ± 4.62 years. The majority had low CD3, low CD4, low CD56, low CD20, and high CD8 positivity in both pre- and post-NACT specimens. On multivariate analysis, low CD3, CD4, CD56 and CD 20 were established as independent predictor of poor pathologic response (PR). Low CD4 (adjusted odds ratio [OR]: 228.46) was associated with the highest OR for poor PR. Low CD8 was associated with significantly decreased odds of poor PR on univariate analysis (OR: 0.26), but it was not been established as an independent predictor of PR on multivariate logistic regression. NACT did not significantly alter the profile of TILs. Conclusions: TIL profile with low CD3, CD4, CD20, and CD56 expression predicts PR to NACT in TNBC and may thus help in prognostication of these patients.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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, ß-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), ß-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.
