RESUMEN
BACKGROUND & AIMS: Chronic liver (CLD) is a major public health concern. We assessed its effects on quality of life and work productivity, as well as its economic burden in the United States. METHODS: We performed a cross-sectional study of data from the Medical Expenditure Panel Survey (MEPS; 2004-2013). We extracted participants' sociodemographic parameters and medical histories. Subjects with CLD were identified based on Clinical Classification Software codes. MEPS participants were compared between those with and without CLD, and then between employed and unemployed patients with CLD. Outcomes were quality-of-life scores, employment, and health care use. RESULTS: We collected data from 230,406 adult participants (age, ≥18 y) in the MEPS; 1846 had current CLD (36.7% with viral hepatitis and 5.3% with liver cancer). Individuals with CLD were less likely to be employed (44.7% vs 69.6% patients without CLD), were not working owing to illness/disability (30.5% vs 6.6% without CLD), lost more work because of disability (10.2 vs 3.4 d without CLD), and had more health care use, producing greater health care expenses ($19,390 vs $5567/y without CLD) (all P < .0001). Patients with CLD also had more comorbidities and worse self-reported general and mental health status, and reported more health-related limitations in their daily activities than individuals without CLD (all P < .0001). They also indicated more psychologic distress and depressive symptoms and had a lower quality of life and health utility scores (P < .0001). In multivariate analysis, after adjustment for sociodemographic factors and comorbidities, the presence of CLD was an important predictor of unemployment (odds ratio, 0.60; 95% confidence interval, 0.50-0.70), annual health care expenditure (ß = $9503 ± $2028), and impairment in all aspects of health-related quality of life (all P < .0001). In patients with CLD, the presence of liver cancer had the most profound impact on health care expenditures (ß = $17,278 ± $5726/y) and physical health (ß = -7.2 ± 1.7 for SF-12 physical component) (all P < .005). CONCLUSIONS: In a cross-sectional analysis of MEPS participants, we associated CLD with large economic and quality-of-life burdens.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is one of the leading causes of chronic liver disease worldwide with tremendous clinical burden. The economic burden of NAFLD is not well studied. GOAL: To assess the economic burden of NAFLD. STUDY: Medicare beneficiaries (January 1, 2010 to December 31, 2010) with NAFLD diagnosis by International Classification of Diseases, Ninth Revision codes in the absence of other liver diseases were selected. Inpatient and outpatient resource utilization parameters were total charges and total provider payments. NAFLD patients with compensated cirrhosis (CC) were compared with decompensated cirrhosis (DC). RESULTS: A total of 976 inpatients and 4742 outpatients with NAFLD were included-87% were white, 36% male, 30% had cardiovascular disease (CVD) or metabolic syndrome conditions, and 12% had cirrhosis. For inpatients, median total hospital charge was $36,289. NAFLD patients with cirrhosis had higher charges and payments than noncirrhotic NAFLD patients ($61,151 vs. $33,863 and $18,804 vs. $10,146, P<0.001). Compared with CC, NAFLD patients with DC had higher charges and payments (P<0.02). For outpatients, median total charge was $9,011. NAFLD patients with cirrhosis had higher charges and payments than noncirrhotic NAFLD patients ($12,049 vs. $8,830 and $2,586 vs. $1,734, P<0.001). Compared with CC, DC patients had higher total charges ($15,187 vs. $10,379, P=0.04). In multivariate analysis, variables associated with increased inpatient resource utilization were inpatient mortality, DC, and CVD; for outpatients, having CVD, obesity, and hypertension (all P<0.001). CONCLUSIONS: NAFLD is associated with significant economic burden to Medicare. Presence of cirrhosis and CVD are associated with increased resource utilization.

BACKGROUND: Hepatocellular carcinoma (HCC) is an important complication of cirrhosis. Our aim was to assess the inpatient economic and mortality of HCC in the USA METHODS: Five cycles of Nationwide Inpatient Sample (NIS) conducted from 2005 to 2009 were used. Demographics, inpatient mortality, severity of illness, payer type, length of stay (LoS) and charges were available. Changes and associated factors related to inpatient HCC were assessed using simple linear regression. Odds ratios and 95% CIs for hospital mortality were analysed using log-linked regression model. To estimate the sampling variances for complex survey data, we used Taylor series approach. SAS(®) v.9.3 was used for statistical analysis. RESULTS: From 2005 to 2009, 32,697,993 inpatient cases were reported to NIS. During these 5 years, primary diagnosis of HCC increased from 4401 (2005), 4170 (2006), 5065 (2007), 6540 (2008) to 6364 (2009). HCC as any diagnosis increased from 68 per 100,000 discharges (2005) to 99 per 100,000 (2009). However, inpatient mortality associated with HCC decreased from 12% (2005) to 10% (2009) (P < 0.046) and LoS remained stable. However, median inflation-adjusted charges at the time of discharge increased from $29,466 per case (2005) to $31,656 per case (2009). Total national HCC charges rose from $1.0 billion (2005) to $2.0 billion (2009). In multivariate analysis, hospital characteristic was independently associated with decreasing in-hospital mortality (all P < 0.05). Liver transplantation for HCC was the main contributor to high inpatient charges. Longer LoS and other procedures also contributed to higher inpatient charges. CONCLUSIONS: There is an increase in the number of inpatient cases of HCC. Although inpatient mortality is decreasing and the LoS is stable, the inpatient charges associated with HCC continue to increase.

OBJECTIVE: The aim of the study is to identify the impact of postacute SARS-CoV-2 infection on patient outcomes. DESIGN: This is a prospective, repeated measure, observational study of consented adults with positive SARS-CoV-2 quantitative polymerase chain reaction or antigen test more than 28 days after infection. Only data from the initial study visit are reported, including disease history, symptoms checklist, patient questionnaires, cognitive tests, social/medical histories, vitals, grip strength, and 2-min walk distance. RESULTS: Two hundred eighteen patients were studied: 100 hospitalized (57.3 ± 15.4 yrs, 62% male, body mass index: 31.3 ± 8.0) and 118 nonhospitalized (46.2 ± 14.6 yrs, 31% male, body mass index: 29.7 ± 7.5). Post-COVID patients reported mean 1.76 symptoms; ≥15% reported fatigue, memory loss, and shortness of breath. Grip strength was 14% lower than norms ( P < 0.0001). Fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue), mood (Patient Health Questionnaire), and well-being (EuroQol 5 Dimension 5 Level) scores were lower than the population norms ( P < 0.05). Hospitalized versus nonhospitalized post-COVID patients performed worse on cognitive assessments (processing speed test-Wechsler Adult Intelligence Scale-Fourth Edition Symbol Search) and reported less regular exercise (≥30 mins ≥3× per week; P < 0.05). In addition, 30% had severe fatigue (by the Functional Assessment of Chronic Illness Therapy-Fatigue); those patients reported less exercise ( P < 0.05). In multivariate models, lack of exercise was independently associated with multiple post-COVID-19 impairments. CONCLUSIONS: Low levels of exercise are an independent risk factor for post-COVID sequelae. Patients who report less exercise have low grip strength, higher levels of fatigue, memory loss, shortness of breath, depression, and poorer quality of life.

Introduction: Many with post-acute SARS-CoV-2 (PASC) have persistent symptoms impacting physical and cognitive function, decreased health and health-related life quality. Monoclonal antibody (mAb) treatment was available to acutely infected patients which might improve these outcomes. Purpose: To compare patient perception of PASC symptoms for those receiving bamlanivimab or casirivimab and imdevimab (mAbs) to those not receiving this treatment (non-mAbs). To compare changes between these groups in symptoms, function and quality of life over a 6-month follow-up. Patients and Methods: Consented adults >28 days post-infection with positive SARS-CoV-2 qPCR or antigen test and SARS-CoV-2 infection between March of 2020 and July of 2022 were enrolled. This prospective, repeated measure observational study reports baseline through 6-month follow-up. Extensive sociodemographic data, detailed medical history, COVID-19 symptom history, and standardized measures of well-being, depression, anxiety, stigma, cognition, symptom assessment, distress, and health status were collected. Results: 323 participants [101 mAb, 221 non-mAb, 52.7±15.5 years, 47.7% male, body mass index (BMI) 31.4±8.4] were analyzed. Fewer symptoms at baseline were reported in mAb versus non-mAb participants (1.06±1.31 vs 1.78±2.15, respectively p=0.0177) 6 months: (0.911±1.276 mAb vs.1.75±2.22 non-mAb, p=0.0427). Both groups showed significant within-group decreases in symptom number (52 to 21 mAb, 126 to 63 non-mAb) and symptom burden (p=0.0088 mAb, p<0.00001 non-mAb). mAb patients had significantly shorter infection-to-baseline interval (days) (120.4±55.3 mAb vs 194.0±89.3 non-mAb, p<0.00001); less frequent history of myocardial infarction (0.0 vs 3.9%, p=0.0464); headache (2.0% vs.11.8%, p=0.0046), rash (3.1% vs 9.9%, p=0.0377), and miscellaneous muscle complaints (2.0% vs 12.3%, p=0.0035), plus significantly better 6-month mood. (2.2% vs 13.2%, p=0.0390). Conclusion: mAb treated participants had reduced symptom burden and consistently reported fewer symptoms than non-mAb at all time points despite less time since acute illness. Both groups reported a statistically significant decrease in symptoms by 6-month visit with no statistically significant differences between them at follow-up.
RESUMEN
BACKGROUND: Hepatitis C virus (HCV) is the most common cause of chronic liver disease in the United States. African Americans are known to have a higher prevalence of HCV and lower response to anti-HCV therapy. GOAL: The aim of this study is to assess the differences in the prevalence of chronic HCV infection in according to patients' ethnic background. STUDY: We used the recent National Health and Nutrition Examination Survey with extensive clinical and laboratory data. Active HCV infection was defined as having HCV-positive antibody with detectable HCV RNA by polymerase chain reaction. HCV clearance was defined as HCV-positive antibody with negative HCV RNA. Clinico-demographic data were compared between anti-HCV positive individuals with or without HCV clearance. The stratum-specific χ test for independence was used. Logistic regression was used to identify independent predictors of HCV clearance. P-values ≤0.05 were considered statistically significant. All analyses were run using SAS 9.1 and SUDAAN 10.0. RESULTS: The cohort included 14,750 adults (age 47.6 ± 0.75 y, 64% white, 21% African American, 10% Hispanics, and 63% male). Of these, 1.32 ± 0.11% were anti-HCV positive with 75.94 ± 4.72% having active HCV viremia. The only parameter significantly different between those who did or did not clear HCV was the proportion of African Americans: 8.0 ± 3.7% versus 24.9 ± 5.0%, P=0.0163. Indeed, the rate of HCV clearance was lowest among African Americans (9.3 ± 3.5%) as compared with both whites (27.2 ± 6.5%) and Hispanics 31.2 ± 9.1% (P<0.05). In multivariate analysis, the only independent predictor of active HCV infection was African American race: odds ratio (95% confidence interval)=3.80 (1.31-11.06), P=0.0151. CONCLUSIONS: African Americans not only have lower response to anti-HCV therapy but also are less likely to naturally clear HCV, potentially contributing to higher prevalence of HCV.

BACKGROUND & AIMS: Chronic liver diseases (CLDs) are major causes of morbidity and mortality worldwide. We assessed changes in the prevalence of different types of CLD in the United States. METHODS: National Health and Nutrition Examination Surveys conducted between 1988 and 2008 were used to estimate changes in the prevalence and predictors of CLDs. Serologic and clinical data were used to establish the diagnoses of CLDs in 39,500 adults. Statistical analyses were conducted with SUDAAN 10.0 (SAS Institute, Inc, Cary, NC). RESULTS: The prevalence rates for CLD were 11.78% (1988-1994), 15.66% (1999-2004), and 14.78% (2005-2008). During the same period, the prevalence of hepatitis B virus infection (0.36%, 0.33%, and 0.34%), hepatitis C virus (1.95%, 1.97%, and 1.68%), and alcoholic liver disease (1.38%, 2.21%, and 2.05%) remained generally stable. In contrast, the prevalence of nonalcoholic fatty liver disease (NAFLD) increased from 5.51% to 9.84% to 11.01%. From 1988 to 1994, NAFLD accounted for 46.8% of CLD cases; from 1994 to 2004 its prevalence increased to 62.84%, and then to 75.1% from 2005 to 2008. During these time periods, steady increases were observed in obesity (21.74%, 30.02%, and 33.22%), visceral obesity (35.18%, 48.16%, and 51.43%), type II diabetes (5.55%, 7.88%, and 9.11%), insulin resistance (23.29%, 32.50%, and 35.00%), and hypertension (22.68%, 33.11%, and 34.08%). A multivariate analysis showed that during all time periods, obesity was an independent predictor of NAFLD. CONCLUSIONS: National Health and Nutrition Examination Surveys data collected from 1988 to 2008 show that the prevalence of major causes of CLD remained stable, except for NAFLD, which increased steadily, along with the prevalence of metabolic conditions. Given the increasing rates of obesity, NAFLD prevalence is expected to contribute substantially to the burden of CLD in the United States.

INTRODUCTION: We aimed to identify high-risk nonalcoholic fatty liver disease (NAFLD) patients seen at the primary care and endocrinology practices and link them to gastrohepatology care. METHODS: Using the electronic health record, patients who either had the diagnosis of type 2 diabetes or had 2 of 3 other metabolic risk factors met criteria for inclusion in the study. Using noninvasive fibrosis tests (NITs) to identify high risk of fibrosis, patients who met the NIT prespecified criteria were referred to gastrohepatology for clinical assessment and transient elastography. RESULTS: From 7,555 patients initially screened, 1707 (22.6%) met the inclusion criteria, 716 (42%) agreed to enroll, and 184 (25.7%) met the prespecified NIT criteria and eligibility for linkage to GE-HEP where 103 patients (68 ± 9 years of age, 50% men, 56% white) agreed to undergo linkage assessments. Their NIT scores were APRI of 0.38 ± 0.24, FIB-4 of 1.98 ± 0.87, and NAFLD Fibrosis Score of 0.36 ± 1.03; 68 (66%) linked patients had controlled attenuation parameter >248 dB/m, 62 (60%) had liver stiffness <6 kPa, and 8 (8%) had liver stiffness >12 kPa. Liver stiffness for the overall group was 6.7 ± 4.2 kPa, controlled attenuation parameter 282 ± 64 dB/m, and FAST score 0.22 ± 0.22. Linked patients with presumed advanced fibrosis had significantly higher body mass index (36.4 ± 6.6 vs 31.2 ± 6.4 kg/m2, P = 0.025) and higher NIT scores (APRI 0.89 ± 0.52 vs 0.33 ± 0.14, FIB-4 3.21 ± 2.06 vs 1.88 ± 0.60, and NAFLD Fibrosis Score 1.58 ± 1.33 vs 0.25 ± 0.94). DISCUSSION: By applying a simple prespecified multistep algorithm using electronic health record with clinical risk factors and NITs followed by transient elastography, patients with nonalcoholic fatty liver disease seen in PCP and ENDO practices can be easily identified.

BACKGROUND: Within the spectrum of nonalcoholic fatty liver disease (NAFLD), only patients with nonalcoholic steatohepatitis (NASH) show convincing evidence for progression. To date, liver biopsy remains the gold standard for the diagnosis of NASH; however, liver biopsy is expensive and associated with a small risk, emphasizing the urgent need for noninvasive diagnostic biomarkers. Recent findings suggest a role for apoptosis and adipocytokines in the pathogenesis of NASH. The aim of this study was to develop a noninvasive diagnostic biomarker for NASH. METHODS: The study included 101 patients with liver biopsies who were tested with enzyme-linked immunosorbent assay (ELISA)-based assays. Of these, 69 were included in the biomarker development set and 32 were included in the biomarker validation set. Clinical data and serum samples were collected at the time of biopsy. Fasting serum samples were assayed for adiponectin, resistin, insulin, glucose, TNF-alpha, IL-6, IL-8, cytokeratin CK-18 (M65 antigen), and caspase-cleaved CK-18 (M30 antigen). RESULTS: Data analysis revealed that the levels of M30 antigen (cleaved CK-18) predicted histological NASH with 70% sensitivity and 83.7% specificity and area under the curve (AUC) = 0.711, p < 10(-4), whereas the predictive value of the levels of intact CK-18 (M65) was higher (63.6% sensitivity and 89.4% specificity and AUC = 0.814, p < 10(-4)). Histological NASH could be predicted by a combination of Cleaved CK-18, a product of the subtraction of Cleaved CK-18 level from intact CK-18 level, serum adiponectin, and serum resistin with a sensitivity of 95.45% sensitivity, specificity of 70.21%, and AUC of 0.908 (p < 10(-4)). Blinded validation of this model confirmed its reliability for separating NASH from simple steatosis. CONCLUSIONS: Four ELISA-based tests were combined to form a simple diagnostic biomarker for NASH.

BACKGROUND: Metabolic syndrome (MS) is common among morbidly obese patients undergoing bariatric surgery. The aim of this study was to assess the impact and predictors of bariatric surgery on the resolution of MS. METHODS: Subjects included 286 patients [age 44.0 +/- 11.5, female 78.2%, BMI 48.7 +/- 9.4, waist circumference 139 +/- 20 cm, AST 23.5 +/- 14.9, ALT 30.0 +/- 20.1, type 2 diabetes mellitus (DM) 30.1% and MS 39.2%] who underwent bariatric surgery. RESULTS: Of the entire cohort, 27.3% underwent malabsorptive surgery, 55.9% underwent restrictive surgery, and 16.8% had combination restrictive-malabsorptive surgery. Mean weight loss was 33.7 +/- 20.1 kg after restrictive surgery (follow up period 298 +/- 271 days), 39.4 +/- 22.9 kg after malabsorptive surgery (follow-up period 306 +/- 290 days), and 28.3 +/- 14.1 kg after combination surgery (follow-up period 281 +/- 239 days). Regardless of the type of bariatric surgery, significant improvements were noted in MS (p values from <0.0001-0.01) as well as its components such as DM (p values from <0.0001-0.0005), waist circumference (p values <0.0001), BMI (p values <0.0001), fasting serum triglycerides (p values <0.0001 to 0.001), and fasting serum glucose (p values <0.0001). Additionally, a significant improvement in AST/ALT ratio (p value = 0.0002) was noted in those undergoing restrictive surgery. Multivariate analysis showed that patients who underwent malabsorptive bariatric procedures experienced a significantly greater percent excess weight loss than patients who underwent restrictive procedures (p value = 0.0451). Percent excess weight loss increased with longer postoperative follow-up (p value <0.0001). CONCLUSIONS: Weight loss after bariatric surgery is associated with a significant improvement in MS and other metabolic factors.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) and obstructive sleep apnoea are associated with metabolic syndrome and atherosclerotic heart disease. This study evaluates the potential association between the NAFLD subtypes and a number of polysomnographical (PSG) parameters. METHODS: This study included patients undergoing bariatric surgery with extensive clinical and histological data for whom complete PSG data before surgery were also available. Excess alcohol intake and other causes of liver disease were excluded. Apnoea, hypopnoea and apnoea-hypopnoea index (AHI) were calculated as described previously. RESULTS: In this study, a total of 101 patients [77 nonalcoholic steatohepatitis (NASH) and 22 non-NASH controls] with PSG data were included (age 42.9 +/- 11.4 years, body mass index 51.6 +/- 9.5 kg/m(2), fasting serum glucose 117.4 +/- 53.4 mg/dl, fasting serum triglycerides 171.3 +/- 82.9 mg/dl, 58% hypertension and 33% diabetes mellitus). Subjects with histological NASH had significantly lower lowest desaturation (77 vs. 85%, P=0.006), lower mean nocturnal oxygen saturation (91 vs. 93%, P=0.05), higher AHI (35 vs. 22, P=0.03), higher respiratory disturbance index (46 vs. 21, P=0.02) and higher alanine aminotransferase/aspartate aminotransferase ratio (1.4 vs. 1.3, P=0.05) compared with non-NASH controls. In multivariate analysis, the lowest desaturation (P=0.04) was independently associated with histological NASH. Lowest desaturation and mean nocturnal oxygen saturation were significantly lower in subjects with fibrosis (76 vs. 85%, P=0.004 and 90.4 vs. 93.0%, P=0.02). CONCLUSIONS: Our results suggest that the frequent nocturnal hypoxic episodes in NAFLD patients may be a risk factor for developing NASH. Additional studies are needed to study the effect of optimizing sleep apnoea management on the outcomes of patients with NAFLD.

Patient-reported outcomes (PROs) such as quality of life and work productivity are important for measuring patient's experience. We assessed PROs during and after treatment of hepatitis C virus (HCV) patients.Data were obtained from a phase 3 open label study of sofosbuvir and ribavirin (SOF + RBV) with and without interferon (IFN). Patients completed 4 PRO assessment instruments (SF-36, Functional Assessment of Chronic Illness Therapy-Fatigue, Chronic Liver Disease Questionnaire- HCV, Work Productivity and Activity-Specific Health Problem) before, during, and after treatment.A total of 533 patients with chronic HCV were enrolled; 28.9% treatment-naïve, 23.1% cirrhotic, 219 received IFN + SOF + RBV and 314 received IFN-free SOF + RBV. At baseline, there were no differences in PROs between the IFN-free and IFN-containing treatment arms (all Pâ>â0.05). During treatment, patients receiving IFN + SOF + RBV had a substantial impairment in their PROs (up to -24.4% by treatment week 12, up to -8.3% at week 4 post-treatment). The PRO decrements seen in the SOF + RBV arm were smaller in magnitude (up to -7.1% by treatment week 12), and all returned to baseline or improved by post-treatment week 4. By 12 weeks after treatment cessation, patients who achieved sustained viral response-12 showed some improvement of PRO scores regardless of the regimen (up to +7.1%, Pâ<â0.0001) or previous treatment experience. In multivariate analysis, the use of IFN was independently associated with lower PROs.IFN-based regimens have a profoundly negative impact to PROs. By contrast, the impact of RBV on these PROs is relatively modest. Achieving HCV cure is associated with improvement of most of the PRO scores.
