RESUMO
Acute-on-chronic liver failure (ACLF) is a global health problem. Little scientific evidence exists on its prevalence in autoimmune hepatitis. Treatment response and mortality outcomes have also been reported differently. The study was conducted to estimate the overall prevalence of ACLF among patients with autoimmune hepatitis (AIH) and determine the associated treatment response and mortality. We scrutinized wide literature in Scopus, PubMed, Embase, Web of Science, and Cochrane, and assessed published articles completely, studies performed and reported from around the globe, until December 07, 2023, according to the PROSPERO registered protocol (CRD42023412176). Studies (retrospective and prospective cohort study type) that stated the ACLF development among established AIH cases were considered. Features of the study, duration of follow-up, and numeric patient information were retrieved from the studies included. The research paper quality was checked for risk of bias. Random effect meta-analysis with metaregression and subsection scrutinies were performed with R. The main outcome was the collective prevalence of ACLF in the AIH patients, whereas treatment response and mortality in AIH-associated ACLF were secondary outcomes. Six studies were involved with confirmed diagnoses in 985 AIH patients for the data synthesis. The pooled prevalence of ACLF in the explored patients was 12% (95% CI: 8-17) ( P =0.01). Heterogeneity was found to be high in the present meta-analysis ( I2 =72%; P < 0.01). For the secondary endpoint analysis, the pooled prevalence of complete remission at 1-year follow-up was 71% (0.52; 0.85), and mortality from the ACLF-AIH patient population was 32% (95% CI: 18-50). Sensitivity analysis showed no influence on the overall estimations of the pooled prevalence of ACLF by omitting studies one by one. One in 10 AIH patients likely present with ACLF. The response to treatment is seen in two-thirds of patients, and mortality is high.

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.

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.

Coronavirus disease 2019 (COVID-19) has hampered health care delivery globally. We evaluated the feasibility, outcomes, and safety of telehepatology in delivering quality care amid the pandemic. A telemedicine setup using smartphones by hepatologists was organized at our tertiary-care center after pilot testing. Consecutive patients availing telehepatology services were recruited between March and July 2020. An adapted model for assessment of telemedicine was used after validity and reliability testing, to evaluate services 7-21 days after index teleconsultation. Of the 1,419 registrations, 1,281 (90.3%) consultations were completed. From 245 randomly surveyed patients, 210 (85.7%) responded (age [years, interquartile range]: 46 [35-56]; 32.3% females). Seventy percent of patients belonged to the middle or lower socio-economic class, whereas 61% were from rural areas. Modes of teleconsultation were audio (54.3%) or hybrid video call (45.7%). Teleconsultation alone was deemed suitable in 88.6% of patients. Diagnosis and compliance rates were 94% and 82.4%, respectively. Patients' convenience rate, satisfaction rate, improvement rate, success rate, and net promoter scores were 99.0%, 85.2%, 49.5%, 46.2% and 70, respectively. Physical and mental quality of life improved in 67.1% and 82.8% of patients, respectively, following index teleconsultation. Person-hours and money spent by patients were significantly lower with teleconsultation (P < 0.001); however, person-hours spent by hospital per teleconsultation were higher than in physical outpatient services (P < 0.001). Dissatisfied patients were more likely to have lower diagnosis rate, unsuitability for teleconsultation, noncompliance, poorer understanding, and uncomfortable conversation during teleconsultation. Connectivity issues (22.9%) were the most common barrier. Three patients, all of whom were advised emergency care during teleconsultation, succumbed to their illness. Conclusion: Telehepatology is a feasible and reasonably effective tool for rendering health care services using smartphones during the COVID-19 pandemic. Systematic implementation, possible integration into routine health care delivery, and formal cost-effectiveness of telehepatology services need further exploration.

OBJECTIVE: Selective intra-arterial radionuclide therapy (SIRT) using radiolabelled microspheres is for the delivery of therapeutic radioisotope to liver cancers and thus, sparing healthy liver. Several radiolabelled microspheres are commercially available. The main issue associated with these microspheres is affordability. Re-188 is a generator produced radionuclide, emits high energy therapeutic beta particle and imageable gamma photons for pre- and post-therapy dosimetry. METHODS: Tc-99m/Re-188 labelled microspheres have been developed and quality control tests have been performed for suitable clinical use. The clinical studies with Re-188 microspheres for SIRT have been performed. Post-therapy images were acquired for dosimetry. RESULTS: The microspheres were found to possess spherical morphology of less than 20 µm size. The quality control revealed the suitability of microspheres for intravenous administration. The preliminary studies in thirty patients demonstrated good retention in tumor and high tumor to normal liver ratio. Re-188 microspheres were well tolerated by patients. Same microspheres labelled with either Tc-99m or Re-188 were used for pretherapy dosimetry and Re-188 labeled microspheres for therapy (SIRT) as a single-day procedure. CONCLUSION: The freeze-dried microspheres may emerge as highly cost-effective candidates for both pre-therapy dosimetry and SIRT and may benefit a large population with inoperable liver cancer.

BACKGROUND & AIMS: The prevalence of anti-hepatitis C virus antibody in Punjab, India is 3.6%, with 728,000 people estimated to have viremic chronic hepatitis C (CHC). The Mukh-Mantri Punjab Hepatitis C Relief Fund, launched on 18th June 2016, provides no-cost generic direct-acting antivirals (DAAs) with sofosbuvirâ¯+â¯ledipasvir⯱â¯ribavirin or sofosbuvirâ¯+â¯daclatasvir⯱â¯ribavirin with the goal of eliminating CHC from Punjab. We assessed the safety and efficacy of decentralized treatment of CHC in a public health care setting. METHODS: Primary care providers from 3 university and 22 district hospitals were trained to provide algorithm-based DAA treatment and supervised by telehealth clinics conducted fortnightly. The diagnosis of cirrhosis was based on clinical and radiological evidence, including aspartate aminotransferase-to-platelet ratio index (APRI ≥2.0) and FIB-4 score (>3.25), or on liver stiffness measurement ≥12.5â¯kPa on Fibroscan®. RESULTS: We enrolled 48,088 individuals with CHC (63.8% male; mean age 42.1â¯years; 80.5% rural; 14.8% compensated cirrhosis; 69.9% genotype [GT] 3) between 18th June 2016 to 31st July 2018. While 36,250 (75.4%) patients completed treatment, 5,497 (11.4%) had treatment interruptions and 6,341 (13.2%) patients are currently ongoing treatment. Sustained virological response at 12â¯weeks after treatment completion (SVR12) was achieved in 91.6% of patients per protocol, 67.6% in intention-to-treat (ITT) analysis, where all interruptions were treated as failures, and 91.2% in a modified ITT analysis where all patients with successful SVR12 in the interruptions arm were included as cured. SVR12 rates in patients with and without cirrhosis and GT3 versus non-GT3 were comparable. The SVR12 rate was 84.4% in patients who had treatment interruptions. CONCLUSION: Decentralized care of patients with CHC using generic all-oral DAA regimens is safe and effective regardless of genotype or presence of cirrhosis. ClinicalTrials.gov number: NCT01110447. LAY SUMMARY: We assessed the safety and efficacy of public health care using no-cost all-oral generic direct-acting antiviral drugs against hepatitis C in the state of Punjab, India. The goal is elimination of chronic hepatitis C (CHC) by 2030 and involves primary care providers at 25 sites in the state. We enrolled 48,088 individuals (63.8% male; mean age 42.1â¯years; 80.5% rural; 14.8% compensated cirrhotic; 69.9% genotype 3) between 18th June 2016 to 31st July 2018. Cure was achieved in 91.6% of patients, demonstrating that decentralized care of CHC with generic all-oral regimens is safe and effective.

BACKGROUND: Liver diseases contribute significantly to the health and economic burden globally. We undertook this study to assess the health system costs, out-of-pocket (OOP) expenditure and extent of financial risk protection associated with treatment of liver disorders in a tertiary care public sector hospital in India. METHODOLOGY: The present study was undertaken in an intensive care unit (ICU) of a tertiary care hospital in North India. It comprised an ICU and an HDU (high dependency unit). Bottom-up micro-costing was undertaken to assess the health system costs. Data on OOP expenditure and indirect costs were collected for 150 liver disorder patients admitted to the ICU or HDU from December 2013 to October 2014. Per-patient and per-bed-day costs of treatment were estimated from both health system and patient perspectives. Financial risk protection was assessed by computing prevalence of catastrophic health expenditure as a result of OOP expenditure. RESULTS: In 2013-2014, health system costs per patient treated in the ICU and HDU were US$2728 [Indian National Rupee (INR) 1,63,664] and US$1966 (INR 1,17,985), respectively. The mean OOP expenditures for treatment in the ICU and HDU were US$2372 (INR 1,42,297) and US$1752 (INR 1,05,093), respectively. Indirect costs of hospitalization in ICU and HDU patients were US$166 (INR 9952) and US$182 (INR 10,903), respectively. CONCLUSION: Treatment of chronic liver disorders poses an economic challenge for both the health system and patients. There is a need to focus on prevention of liver disorders, and finding ways to treat patients without exposing their households to the catastrophic effect of OOP expenditure.

BACKGROUND AND AIMS: The patients with end stage renal disease (ESRD) are at greater risk of acquiring chronic hepatitis B or C and subsequently development of liver disease. The aim of the study was to assess liver fibrosis by transient elastography (TE) and look for factors associated with change in liver stiffness measurement (LSM) with one session of hemodialysis (HD). METHODS: Consecutive ESRD patients on maintenance hemodialysis (MHD) with suspected liver disease were enrolled. They underwent LSM by TE before and after one session of HD. Bioelectric impedance analysis was done to evaluate the volume status at the time of TE. RESULTS: Sixty-eight patients with mean age of 40 ± 14 years were included. There was a significant reduction in LSM after HD (18.5 [95% CI 14.8-23.1] vs. 11.2 [95% CI 8.8-13.7] kPa, p < 0.001), with a mean LSM reduction of 7.2 [95% CI 5.25-9.19] kPa. On stratification in two groups by net ultrafiltration during HD (> or < 2.5 liters [L]), change in LSM was substantially higher in patients when total fluid removed was > 2.5 L (8.6 [95% CI 5.7-11.5] vs. 5.1 [95% CI 2.9-7.5], p = 0.05). In 18 patients who underwent liver biopsy, LSM after HD performed better at detecting significant fibrosis, with area under receiver operating characteristics curve 0.71 [95% CI 0.46-0.97], versus 0.64 [95% CI 0.38-0.90], respectively. An LSM value of 12.2 kPa after HD was 71% sensitive and 74% specific for detection of significant fibrosis (≥ F2), while values less than 9 kPa ruled out significant fibrosis with a sensitivity and specificity of 37 and 100%, respectively. CONCLUSION: LSM by TE decreases significantly after HD in patients with ESRD on long-term MHD. Hence, TE should be done after HD for accurate assessment of liver fibrosis.

Drug induced liver injury is a common cause of acute liver failure (ALF). While most of these cases are due to dose dependent hepatotoxicity with acetaminophen, idiosyncratic drug-induced liver injury (DILI) is responsible for about 15% cases of ALF. Antibiotics are the most common cause of idiosyncratic DILI as well as DILI induced ALF. Etodolac is a selective cycloxygenase- 2 (COX -2) inhibitor non-steroidal anti-inflammatory drug used as an analgesic and anti-inflammatory in musculoskeletal diseases. Severe liver impairment is extremely rare. Till date, only 3 cases of ALF related to etodolac have been reported in the literature. Here we report two cases with a unique presentation of ALF occurring due to DILI caused by etodolac, as diagnosed by Roussel Uclaf Causality Assessment Method (RUCAM).

Various case-control studies have shown association of single nucleotide polymorphism rs12303764(G/T) in ULK1 with crohn's disease. The techniques used in these studies were time consuming, complicated and require sophisticated/expensive instruments. Therefore, in order to overcome these problems, we have developed a new, rapid and cost effective Tetra-primer ARMS-PCR assay to genotype single nucleotide polymorphism rs12303764(G/T) of ULK1 gene. We manually designed allele specific primers. DNA fragment amplified using outer primers was sequenced to obtain samples with known genotypes (GG, GT and TT) for further use in the development of T-ARMS-PCR assay. Amplification conditions were optimized for parameters; annealing temperature, Taq DNA polymerase and primers. The developed T-ARMS-PCR assay was applied to genotype one hundred samples from healthy individuals. Genotyping results of 10 DNA samples from healthy individuals for rs12303764(G/T) by T-ARMS-PCR assay and sequencing were concordant. The newly developed assay was further applied to genotype samples from 100 healthy individuals of North Indian origin. Genotype frequencies were 9, 34 and 57 % for GG, GT and TT, respectively. Allele frequencies were 0.26 and 0.74 for G and T, respectively. The allele frequencies were in Hardy-Weinberg's equilibrium (p = 0.2443). T-ARMS-PCR assay developed in our laboratory for genotyping rs12303764 (G/T) of ULK1 gene is time saving and cost-effective as compared to the available methods. Furthermore, this is the first study reporting allelic and genotype frequencies of ULK1 rs12303764 (G/T) variants in North Indian population.

BACKGROUND: Liver fibrosis and its sequel cirrhosis represent a major health care burden, and assessment of fibrosis by biopsy is gradually being replaced by noninvasive methods. In clinical practice, the determination of fibrosis stage is important, since patients with advanced fibrosis have faster progression to cirrhosis and antiviral therapy is indicated in these patients. AIMS: To assess the role of transient elastography (TE) and compare it with APRI and FIB4 for predicting liver fibrosis and assessing the effect of host and viral factors on fibrosis and treatment outcome in CHC patients. METHODS: In a retrospective analysis, 330 CHC patients underwent liver stiffness measurement (LSM) by TE and tests needed for calculating APRI and FIB4 scores at baseline. 228 patients received a combination of Pegylated IFN-based antiviral therapy and were analyzed for therapeutic response. RESULTS: The study included 330 patients (median age 39 years [range 18-67]), predominantly males (n = 227, 68.8%) with baseline LSMs. The median liver stiffness was 7.8 kPa (range 3.2-69.1 kPa). LSMs and its thresholds for severe fibrosis progression (≥9.5 kPa) and cirrhosis (≥12.5 kPa) were significantly higher in patients with age ≥40 years, diabetes mellitus, and patients with significant alcohol intake (P = 0.003 to P < 0.001). By taking TE as a reference, the diagnostic accuracy of FIB4 scores for predicting cirrhosis (AUROC 0.896) was good (+LR 13.4) compared to APRI (AUROC 0.823) with moderate likelihood ratio (+LR 6.9). Among 228 treated patients the SVR rate in genotype 3 was 70% versus 57.8% in genotype 1. Fibrosis score F4 (P = 0.023) and HCV genotype (P = 0.008) were independent predictors of SVR. CONCLUSION: The study shows that LSM by TE and fibrosis assessment by FIB4/APRI scores can be used with fair reliability to predict fibrosis and treatment response in patients with CHC infection.
RESUMO
AIM: To compare the utility of the Chronic Liver Failure-Sequential Organ Failure Assessment (CLIF-SOFA) and Asia-Pacific Association for the Study of Liver (APASL) definitions of acute-on-chronic liver failure (ACLF) in predicting short-term prognosis of patients with ACLF. METHODS: Consecutive patients of cirrhosis with acute decompensation were prospectively included. They were grouped into ACLF and no ACLF groups as per CLIF-SOFA and APASL criteria. Patients were followed up for 3 mo from inclusion or mortality whichever was earlier. Mortality at 28-d and 90-d was compared between no ACLF and ACLF groups as per both criteria. Mortality was also compared between different grades of ACLF as per CLIF-SOFA criteria. Prognostic scores like CLIF-SOFA, Acute Physiology and Chronic Health Evaluation (APACHE)-II, Child-Pugh and Model for End-Stage Liver Disease (MELD) scores were evaluated for their ability to predict 28-d mortality using area under receiver operating curves (AUROC). RESULTS: Of 50 patients, 38 had ACLF as per CLIF-SOFA and 19 as per APASL criteria. Males (86%) were predominant, alcoholic liver disease (68%) was the most common etiology of cirrhosis, sepsis (66%) was the most common cause of acute decompensation while infection (66%) was the most common precipitant of acute decompensation. The 28-d mortality in no ACLF and ACLF groups was 8.3% and 47.4% (P = 0.018) as per CLIF-SOFA and 39% and 37% (P = 0.895) as per APASL criteria. The 28-d mortality in patients with no ACLF (n = 12), ACLF grade 1 (n = 11), ACLF grade 2 (n = 14) and ACLF grade 3 (n = 13) as per CLIF-SOFA criteria was 8.3%, 18.2%, 42.9% and 76.9% (χ(2) for trend, P = 0.002) and 90-d mortality was 16.7%, 27.3%, 78.6% and 100% (χ(2) for trend, P < 0.0001) respectively. Patients with prior decompensation had similar 28-d and 90-d mortality (39.3% and 53.6%) as patients without prior decompensation (36.4% and 63.6%) (P = NS). AUROCs for 28-d mortality were 0.795, 0.787, 0.739 and 0.710 for CLIF-SOFA, APACHE-II, Child-Pugh and MELD scores respectively. On multivariate analysis of these scores, CLIF-SOFA was the only significant independent predictor of mortality with an odds ratio 1.538 (95%CI: 1.078-2.194). CONCLUSION: CLIF-SOFA criteria is better than APASL criteria to classify patients into ACLF based on their prognosis. CLIF-SOFA score is the best predictor of short-term mortality.

BACKGROUND/AIMS: The role of model for end-stage liver disease (MELD) among Indian patients with cirrhosis is uncertain. We studied and compared MELD with Child-Turcotte-Pugh (CTP) and creatinine-modified-CTP (CrCTP) scores for predicting 1-, 3-, and 6-months mortality. METHODS: One-hundred and two patients with cirrhosis were studied. The CrCTP was calculated by adding creatinine score of 0, 2 and 4 with creatinine levels of ≤1.2mg/dL, 1.3-1.8 mg/dL and ≥1.9mg/dL, respectively to CTP score. Survival curves were plotted and receiver operating characteristics (ROC) curves were used to compare the scores. Predictors of mortality were analyzed using Cox proportional hazards model. RESULTS: Scores of CTP, CrCTP, and MELD have excellent diagnostic accuracy for predicting mortality (c-statistics >0.85). The MELD was superior to CTP for predicting 3-months [c-statistic and 95% confidence interval, 0.967 (0.911-0.992) vs 0.884 (0.806-0.939)] and 6-months [0.977 (0.925-0.996) vs 0.908 (0.835-0.956)] mortality (P=0.05), while CrCTP [0.958 (0.899-0.988)] was better than CTP for predicting 3-months mortality (P=0.02). Serum creatinine (hazard ratio 4.43, P<0.0001) is a strong independent predictor of mortality. CONCLUSION: The MELD accurately predicts mortality in cirrhosis and is better than CTP for predicting the short-term and intermediate-term mortality. Adding serum creatinine to CTP though significantly improves its diagnostic accuracy for short-term mortality; however, it remains lower than MELD alone.
RESUMO
INTRODUCTION: Insulin resistance (IR) is common in patients with nonalcoholic fatty liver disease (NAFLD). We compared the performance of insulin tolerance test and the homeostasis model assessment (HOMA) for measuring IR in such patients. METHODS: In a prospective study, IR was determined using both insulin tolerance test and HOMA in 22 patients with NAFLD. Rate constant for insulin tolerance test (KITT) was calculated using the formula KITT (%/min) = 0.693/t(1/2), where t(1/2) was calculated from the slope of plasma glucose concentration during 3-15 minutes after administration of intravenous insulin. IR was assessed using HOMA as the product of fasting insulin (microU/L) and fasting plasma glucose (mmol/L) levels divided by 22.5. RESULTS: All the 22 patients had IR. Results of KITT and HOMA-IR for determining IR showed a fair correlation (r = 0.55; p = 0.03). CONCLUSIONS: Insulin tolerance test may be a useful method for assessing IR in patients with NAFLD.

While King's Hospital Criteria (KCH) criteria are used worldwide, the Model for End-Stage Liver Disease (MELD) is a more recently developed scoring system that has been validated as an independent predictor of patient survival in conditions for liver transplantation (LT). The aim of the present study was to compare MELD and KCH criteria with other early clinical prognostic indicators (CPI) in a cohort of patients with fulminant hepatic failure (FHF). A total of 144 patients (mean age 31.7 +/- 14.7 yr; range 12-82 yr; 62 males) with FHF due to acute viral hepatitis were included into the study. Variables found significant on univariate analysis were entered into a multivariate logistic regression analysis. A total of 52 (36.1%) patients survived, the remaining 92 (63.9%) died. Univariate analysis showed that age, duration of jaundice, jaundice-encephalopathy interval (JEI), grade of encephalopathy, presence of cerebral edema, bilirubin, prothrombin time, creatinine, and MELD score were significantly different between survivors and nonsurvivors. Multivariate logistic regression identified 6 independent CPI of adverse outcome on admission: age >or=50 yr, JEI >7 days, grade 3 or 4 encephalopathy, presence of cerebral edema, prothrombin time >or=35 seconds, and creatinine >or=1.5 mg/dL. Presence of any 3 of 6 CPI was optimum in identifying survivors and nonsurvivors. A MELD score of >or=33 was found to be best discriminant between survivors and nonsurvivors by the construction of receiver operating characteristic (ROC) curves. Any 3 CPI were superior to MELD and KCH criteria in predicting the outcome (c-statistic [95% confidence interval]: CPI 0.802 [0.726-0.878], MELD 0.717 [0.636-0.789], and KCH criteria 0.676 (0.588-0.764); P values: CPI vs. MELD 0.045, CPI vs. KCH criteria 0.019, and MELD vs. KCH criteria 0.472). In conclusion, MELD and KCH criteria are not as useful as a combination of other early CPI in predicting adverse outcome in patients with FHF due to acute viral hepatitis.

INTRODUCTION: Insulin resistance plays a major role in the pathogenesis of nonalcoholic steatohepatitis (NASH). Insulin-sensitizing drugs like metformin may have a role in the treatment of this disease. OBJECTIVE: To determine insulin resistance and the role of metformin in the treatment of NASH. METHODS: We prospectively studied 25 patients with NASH over a period of one and a half years. In addition to clinicopathological profile, we studied the insulin resistance by insulin tolerance test in 10 of them; seven of them, who did not respond to 3 months of low-calorie, low-fat diet, exercise, weight reduction and ursodeoxycholic acid (UDCA), were treated with metformin for six months. Results were compared with control groups. RESULTS: All 10 patients with NASH tested had low insulin sensitivity; there was significant difference in the rate constant for insulin sensitivity (Kitt) between patients with NASH and normal volunteers. Thirteen (52%) patients responded to dietary restriction, exercise, weight reduction and UDCA. Four of 7 patients treated with metformin had normalization of ALT. CONCLUSION: Patients with NASH have insulin resistance. Metformin may have a role in the treatment of these patients.
