RESUMEN

Objective: To evaluate the association between subclinical hypothyroidism and hepatic steatosis and fibrosis using the noninvasive diagnostic methods transient hepatic elastography (TE) and controlled attenuation parameter (CAP) in patients with subclinical hypothyroidism. Subjects and methods: This was a cross-sectional study including women with confirmed spontaneous subclinical hypothyroidism and an age- and body mass index (BMI)-matched control group without thyroid disease or circulating antithyroperoxidase (anti-TPO) antibodies. Exclusion criteria were age > 65 years, thyroid-stimulating hormone (TSH) > 10.0 mIUI/L, BMI ≥ 35 kg/m2, diabetes, or other chronic liver diseases. Liver stiffness was classified according to TE values (in kPa) and ranged from absence of fibrosis (F0) to advanced fibrosis (F3). Hepatic steatosis was classified according to CAP values (in dB/m) and ranged from low-grade (S1) to advanced (S3) steatosis. Results: Of 68 women enrolled, 27 were included in the subclinical hypothyroidism group and 41 in the control group. Advanced steatosis (S3) was more frequent in the subclinical hypothyroidism group (25.9% versus 7.3%, respectively, p = 0.034). Circulating anti-TPO was an independent factor associated with advanced steatosis (odds ratio 9.5, 95% confidence interval 1.3-68.3). In multiple linear regression analysis, TE values (which evaluated fibrosis) correlated negatively with free thyroxine levels. Conclusion: The results of this study strengthen the hypothesis that hepatic steatosis is associated with autoimmune (positive anti-TPO) subclinical hypothyroidism, independently from BMI. However, subclinical hypothyroidism alone does not appear to be associated with a significantly increased risk of hepatic fibrosis.

RESUMEN

OBJECTIVE: Primary biliary cholangitis is a chronic and progressive autoimmune liver disease, whose prognosis can be improved by normalizing alkaline phosphatase and bilirubin. While ursodeoxycholic acid (UDCA) is first line standard of care, approximately 40 % of patients exhibit incomplete response. We aimed to identify prognostic markers for deep response to UDCA therapy at presentation. PATIENT AND METHODS: Data from the Brazilian Cholestasis Study Group cohort were analyzed retrospectively. Patients were assessed for deep response, defined as normal alkaline phosphatase and bilirubin, after 1 year of UDCA treatment. Additionally, the performance of the UDCA response score in predicting deep response was evaluated. RESULTS: A total of 297 patients were analyzed, with 57.2 % achieving an adequate response according to the Toronto criteria, while 22.9 % reached deep response. Cirrhosis (OR 0.460; 95 % CI 0.225-0.942; p = 0.034) and elevated baseline alkaline phosphatase levels (OR 0.629; 95 % CI 0.513-0.770; p < 0.001) were associated with reduced odds of deep response. The UDCA response score exhibited moderate discrimination power (AUROC = 0.769) but lacked calibration. CONCLUSIONS: Baseline ALP and liver fibrosis emerge as the most important prognostic factors to predict normalization of alkaline phosphatase and bilirubin after UDCA. The UDCA response score was inadequate for predicting deep response in the Brazilian PBC population.

RESUMEN

BACKGROUND: The performance and reliability criteria for Aixplorer MACH30 (SS) in chronic liver diseases (CLD) have not been validated. AIMS: The objectives were to define the optimal procedure, the accuracy for fibrosis and steatosis diagnosis, and the reliability criteria using SS. METHODS: Patients had 2D-shear wave elastography (SWE) and ultraSound-guided controlled attenuation parameter (SCAP) performed in triplicate at the mid-axillary line (MAL), posterior axillary line (PAL), and anterior axillary line (AAL). Performances of SWE and SCAP were defined using transient elastography (TE ≥ 9.5 kPa) and CAP (≥ 275 dB/m) using Fibroscan (FS) as reference and validated with liver biopsy (LB). RESULTS: FS and SS data from 203 CLD patients were analyzed (55 ± 14 years; 59% male; MASLD 58%). Median TE and CAP were 6.4 kPa (2.5-66.9) and 270 dB/m (141-400). The best technique for the diagnosis of advanced fibrosis and significant steatosis was the median of three SWE values and three SCAP values at MAL, PAL, and AAL with an AUROC of 0.96 [95% CI 0.93-0.98] and 0.91 [95% CI 0.86-0.95]. Only skin-to-liver distance ≥ 2.4 cm (p = 0.012, 95% CI 1.37-13.38) was independently associated with discordance. The accuracy of SWE (≥ 8.5 kPa) and SCAP (≥ 0.44) was analyzed in 58 patients with LB. The PPV and NPV were 50% and 94%, and 71% and 88% for fibrosis and steatosis, respectively. CONCLUSION: A reliable diagnosis of advanced fibrosis and significant steatosis can be obtained with the median of three measurements in different liver portions using SS. The only non-reliable criterion is skin-to-liver distance ≥ 2.4 cm.

RESUMEN

OBJECTIVE: The objective of this study was to evaluate the effects of body weight variability (BWV) on the occurrence of adverse liver outcomes in individuals with type 2 diabetes (T2D) and metabolic dysfunction-associated steatotic liver disease (MASLD). METHODS: A total of 549 patients with T2D and MASLD had BWV parameters assessed during the first 2 years of follow-up. The associations between increasing BWV and liver outcomes (clinical cirrhosis or a liver stiffness measurement on transient elastography > 15 kPa, performed after a median of 7 years of cohort entry) were examined by multivariable logistic regressions. Interaction/subgroup analyses were performed according to participants' physical activity during the initial 2-year period. RESULTS: Individuals were followed up for an additional median 9.7 years, over which 34 liver outcomes occurred (14 with clinical cirrhosis and 20 with liver stiffness measurement > 15 kPa). A 1-SD increase in weight SD and average real variability was associated with 52% higher (95% CI: 4%-128%) odds of having an adverse liver outcome. Otherwise, in interaction/subgroup analyses, an increased BWV was associated with a higher likelihood of outcomes only in sedentary individuals. CONCLUSIONS: Increased BWV was associated with adverse liver outcomes in individuals with T2D and MASLD; however, in those who were physically active, it was not hazardous.

RESUMEN

BACKGROUND: Ursodeoxycholic acid (UDCA) is the standard treatment for primary biliary cholangitis (PBC), but a significant proportion of patients do not respond adequately, leading to increased risk of adverse outcomes. This study aims to develop a new and straightforward predictive score to identify PBC patients likely to achieve a complete response to UDCA. METHODS: A logistic regression analysis was conducted using a derivation cohort of PBC patients to identify pre-treatment variables associated with response to UDCA. This analysis led to the development of the ALP-A score, calculated as: Age at diagnosis divided by (alkaline phosphatase at diagnosis/upper limit of normal). ALP-A score accuracy was evaluated using the area under the ROC curve, validated with a large external cohort from Brazil. Additionally, the correlation between the ALP-A score and the previously validated UDCA response score (URS) was assessed. RESULTS: ALP-A score had good predictive power for adequate (AUC 0.794; 95% CI, 0.737-0.852) and deep (0.76; 95% CI, 0.69-0.83) UDCA response at 1 year of treatment. A cutoff score of 17 and 23 points was determined to be the optimal threshold for distinguishing adequate and deep responders, respectively, from non-responders. ALP-A score demonstrated a sensitivity of 73%, specificity of 71%, positive predictive value of 65%, negative predictive value of 78%, and overall accuracy of 72% for biochemical response. The URS displayed similar discriminative ability (AUC 0.798; 95% CI, 0.741-0.855). CONCLUSION: ALP-A score performs comparably to URS but offers the great advantage of simplicity for routine clinical use. It serves as a valuable tool to identify PBC patients less likely to respond to UDCA treatment, facilitating early consideration of alternative therapeutic approaches.

RESUMEN

INTRODUCTION AND OBJECTIVES: A high prevalence of steatotic liver disease has been described in psoriasis. However, the influence of genetic polymorphisms has yet to be investigated in this scenario. This study aims to determine the frequency of steatosis, advanced liver fibrosis and PNPLA3/TM6SF2 genotypes in individuals with psoriasis and to evaluate the impact of genetic polymorphisms, metabolic parameters and cumulative methotrexate dose on steatosis and fibrosis. MATERIALS AND METHODS: Cross-sectional study that prospectively included psoriasis outpatients, submitted to clinical and laboratory analysis, transient elastography (FibroScan®, Fr) and PNPLA3/TM6SF2 genotyping. Steatosis was defined by CAP ≥275 dB/m and advanced liver fibrosis as transient elastography ≥10 kPa. Logistic regression analysis evaluated the independent variables related to steatosis and fibrosis; p-value< 0.05 was considered significant. RESULTS: One hundred and ninety-nine patients were enrolled (age 54.6 ± 12.6 years, 57.3% female). Metabolic syndrome (MetS), steatosis and advanced liver fibrosis prevalence were 55.8%, 54.8% and 9%, respectively. PNPLA3 and TM6SF2 genotypes frequencies were CC 42.3%/CG 49.5%/GG 8.2% and CC 88.7%/ CT 11.3%/ TT 0%. MetS (OR3.01 95%CI 1.51-5.98; p = 0.002) and body mass index (OR1.17 95%CI 1.08-1.26; p < 0.01) were independently associated with steatosis. Diabetes Mellitus (T2DM) (OR10.76 95%CI 2.42-47.87; p = 0.002) and harboring at least one PNPLA3 G allele (OR5.66 95%CI 1.08-29.52; p = 0.039) were associated with advanced fibrosis, but not TM6SF2 polymorphism or cumulative MTX dose. CONCLUSIONS: MetS and T2DM confer higher odds for steatosis and advanced fibrosis in individuals with psoriasis. PNPLA3 G allele, but not TM6SF2 polymorphism, impacts a 5-fold odds of advanced liver fibrosis.

RESUMEN

BACKGROUND/AIMS: Longitudinal studies assessing the impact of genetic polymorphisms on outcomes in patients with Type 2 Diabetes Mellitus (T2DM) and Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) are scarce. This study aimed to evaluate the effect of PNPLA3 and TM6SF2 risk alleles on hepatic and extrahepatic outcomes in T2DM-MASLD individuals. METHODS: Patients' polymorphisms were analysed as follows: PNPLA3 CC, CG and GG; TM6SF2 CC and CT + TT; combined comparing no mutant allele, one allele G or T or ≥2 alleles G or T. Hierarchical models were built to assess associations between polymorphisms and outcomes, independently of confounding factors. Multivariate logistic regression was used for cirrhosis and its complications and extrahepatic cancer, and Cox regression for cardiovascular events (CVEs) and all-cause mortality. RESULTS: In total, 407 T2DM-MASLD patients (62.1 ± 10.5 years, 67.6% women) were followed for 11 (6-13) years. Having at least one G or T allele independently increased the risk of cirrhosis in the separate analysis of PNPLA3 and TM6SF2. Combined polymorphism analysis demonstrated an even higher risk of cirrhosis if two or more risk alleles were present (OR 18.48; 95% CI 6.15-55.58; p < .001). Regarding cirrhosis complications, the risk was higher in PNPLA3 GG and TM6SF2 CT + TT, also with an even higher risk when two or more risk alleles were present in the combined evaluation (OR 27.20; 95% CI 5.26-140.62; p < .001). There were no associations with CVEs or mortality outcomes. CONCLUSION: In T2DM, PNPLA3 and TM6SF2 polymorphisms, individually and additively, impact MASLD severity, with an increased risk of cirrhosis and its complications.

RESUMEN

BACKGROUND & AIMS: In non-alcoholic fatty liver disease (NAFLD), the influence of parental history of type 2 diabetes (T2D) allied to single nucleotide polymorphisms (SNPs) in the offspring is not known. We aimed to investigate the impact of the parental history of T2D, PNPLA3 and TM6SF2 polymorphisms in liver steatosis and fibrosis. METHODS: This was a case-control study involving the offspring of T2D patients and controls without a parental history of T2D. Participants underwent clinical and laboratory evaluation, transient elastography (TE) by Fibroscan® (Echosens, Fr) and genotyping for PNPLA3 and TM6SF2. Multivariate logistic regression evaluated the influence of parental history of T2D on liver steatosis and fibrosis, controlled for age, gender, metabolic traits and SNPs. RESULTS: 161 T2D offspring and 78 controls, 10-46 years old, were included. The offspring of T2D had higher prevalences of obesity, T2D, arterial hypertension and sedentarism. Parental history of T2D was associated with fibrosis ≥ F2 (OR 8.89, CI 95% 1.09-72.01, p = 0.041) after adjustment for age, gender, metabolic traits and SNPs. PNPLA3 GG genotype was independently associated with steatosis ≥ S1 (OR 8.15, CI 95% 1.93-34.38, p = 0.004) and fibrosis ≥ F2 (OR 4.31, CI 95% 1.11-16.61, p = 0.034). CONCLUSIONS: The offspring of T2D patients present a worse metabolic profile and the parental history of T2D confers an increased likelihood of hepatic fibrosis, independent of metabolic factors. PNPLA3 homozygous GG, but not TM6SF2 genotypes, also impacts on this phenotype.

RESUMEN

Introduction: Metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as Nonalcoholic fatty liver disease (NAFLD), is one of the most common hepatic diseases in individuals with overweight or obesity. In this context, a panel of experts from three medical societies was organized to develop an evidence-based guideline on the screening, diagnosis, treatment, and follow-up of MASLD. Material and methods: A MEDLINE search was performed to identify randomized clinical trials, meta-analyses, cohort studies, observational studies, and other relevant studies on NAFLD. In the absence of studies on a certain topic or when the quality of the study was not adequate, the opinion of experts was adopted. Classes of Recommendation and Levels of Evidence were determined using prespecified criteria. Results: Based on the literature review, 48 specific recommendations were elaborated, including 11 on screening and diagnosis, 9 on follow-up,14 on nonpharmacologic treatment, and 14 on pharmacologic and surgical treatment. Conclusion: A literature search allowed the development of evidence-based guidelines on the screening, diagnosis, treatment, and follow-up of MASLD in individuals with overweight or obesity.

RESUMEN

BACKGROUND & AIMS: To date, no specific drugs are available for non-alcoholic fatty liver disease (NAFLD), though the effect of fish oil supplementation on improving fibrosis in patients with NAFLD has been evaluated. N-3 polyunsaturated fatty acids (n-3 PUFA) may modulate the concentration of microRNAs (miRNAs) and fibroblast growth factor (FGF)-21, which have been identified as non-invasive markers of liver fibrosis. The present study aims to evaluate whether n-3 PUFA supplementation can modulate miRNA-122 and FGF-21 and improve liver fibrosis and steatosis, measured by transient hepatic elastography (THE), in individuals with NAFLD. METHODS: A randomized, double-blind, placebo-controlled clinical trial will be conducted to evaluate the effect of 4 g/day supplementation of fish oil (2100 mg EPA and 924 mg DHA) in patients with NAFLD over a 6-month period. Fifty-two patients aged >19 years will be randomly assigned to either a placebo (olive oil) or treatment (fish oil) group. Anthropometric data, food intake, physical activity, body composition, resting energy expenditure (evaluated using indirect calorimetry), liver enzymes, platelets, lipids and glucose profile, inflammatory markers (such as C-reactive protein, neutrophil/lymphocyte, platelet/lymphocyte, and monocyte/lymphocyte ratios), miRNA-122 and FGF-21 concentration, and incorporation of fatty acids into the erythrocyte membrane (analyzed using gas chromatography) as well as the degree of liver fibrosis and steatosis assessed using THE (Fibroscan® Touch 502, Paris, France) and liver biomarkers Steato-Brazilian Longitudinal Study of Adult Health, Fatty Liver Index, NAFLD Fibrosis Score, Fibrosis-4 score, and FibroScan-AST score will be evaluated at the beginning and end of the treatment. Continuous variables with normal distribution will be compared between placebo and intervention groups using Student's T test for independent samples; continuous non-parametric variables will be compared using Dunn or Mann-Whitney test. Associations between categorical variables will be analyzed using the chi-square test, and within-group differences will be evaluated using the Wilcoxon signed-ranks test. The criterion for determining significance will be set at 5%. CONCLUSION: The present study protocol will investigate the supplementation of EPA-rich fish oil as an alternative treatment for NAFLD and its feasibility in affecting the concentration of miRNA-122 and FGF-21 markers. Its findings will offer valuable contributions to the literature. REGISTRATION: ReBEC number RBR-8dp876.

RESUMEN

Data on the acceptability and usability of hepatitis C virus self-testing (HCVST) remain scarce. We estimated the pooled rates of acceptability/feasibility and re-reading/re-testing agreement of HCVST using oral fluid tests (PROSPERO-CRD42022349874). We searched online databases for studies that evaluated acceptability, usability and inter-reader/operator variability for HCVST using oral fluid tests. Pooled estimates of feasibility, agreement and post-testing perspectives were analysed. Sensitivity analyses were performed in men who have sex with men (MSM) and people who inject drugs (PWID). Heterogeneity was assessed using the I2 statistics. A total of six studies comprising 870 participants were identified: USA (n = 95 with liver disease), Kenya (n = 150 PWID), Egypt (n = 116 from the general population), Vietnam (n = 104 MSM and n = 105 PWID), China (n = 100 MSM) and Georgia (n = 100 MSM and n = 100 PWID)]. All studies used OraQuick® HCV Rapid Antibody Test. The pooled overall estimates for correct sample collection and for people who performed HCVST without needing assistance in any step (95% confidence interval [CI]) were 87.2% [76.0-95.3] (n = 755; I2 = 93.7%) and 62.6% [37.2-84.8] (n = 755; I2 = 98.0%), respectively. The pooled estimate of agreement for re-reading was 95.0% [95% CI 91.5-97.6] (n = 831; I2 = 74.0%) and for re-testing was 94.4% [90.3-97.5] (n = 726; I2 = 77.1%). The pooled estimate of those who would recommend HCVST was 94.4% [84.7-99.6] (n = 625; I2 = 93.7%). Pooled estimates (95% CI) of correct sample collection (72.8% [63.3-81.5] vs. 90.8% [85.9-94.8]) and performance of HCVST without needing assistance (44.1% [14.1-76.7] vs. 78.1% [53.4-95.3]) was lower in PWID compared to MSM. In summary, HCV testing with oral fluid HCVST was feasible and well-accepted. Oral fluid HCVST should be considered in key populations for uptake HCV testing.

RESUMEN

INTRODUCTION AND OBJECTIVES: The agreement of elastography techniques in chronic Hepatitis B (CHB) needs evaluation. We aimed to evaluate, in CHB, the agreement between transient elastography (TE) and two-dimensional shear wave elastography (2D-SWE), analyzing the factors related to the disagreement of measures. MATERIALS AND METHODS: CHB patients underwent liver stiffness measures with both TE and 2D-SWE on the same day. For concordance analysis, we defined liver fibrosis as F0/1 vs. F ≥ 2, F0/1-F2 vs. F ≥ 3 and F0/1-F2-F3 vs. F4 for both methods. Logistic regression analysis was used to identify the variables independently associated with the disagreement between methods. RESULTS: A total of 150 patients were enrolled. Liver fibrosis categorization according to TE was: F0-F1 = 73 (50.4%), F ≥ 2 = 40 (27.6%), F ≥ 3 = 21 (14.5%) and F4 = 11 (7.6%), and according to 2D-SWE was: F0/F1 = 113 (77.9%), F ≥ 2 = 32 (22.1%), F≥ 3 = 25 (17.2%) and F4 = 11 (7.6%). It was observed that 20.0% of the sample had steatosis (CAP≥ 275 dB/m). TE and SD-SWE estimated equal fibrosis stages in 79.3% of cases. Spearman's correlation coefficient was 0.71 (p < 0.01). Kappa values for F ≥ 2, F ≥ 3 and F = 4 were: 0.78, p < 0.001; 0.73, p < 0.001; and 0.64, p < 0.001, respectively. Diabetes mellitus (DM) (OR 5.04; 95%CI: 1.89-13.3; p < 0.001) and antiviral treatment (OR 6.79; 95%CI: 2.33-19.83; p < 0.001) were independently associated with discordance between both methods. CONCLUSIONS: In CHB, there is strong correlation and good agreement between TE and 2D-SWE in identifying fibrosis stages. Diabetes mellitus and antiviral therapy may impact the agreement of stiffness measures obtained with these elastographic methods.

RESUMEN

INTRODUCTION AND OBJECTIVES: Primary biliary cholangitis (PBC) and autoimmune hepatitis (AIH) and PBC overlap syndrome (AIH/PBC) have been associated with a higher risk of hepatocellular carcinoma (HCC) and extra-hepatic malignancy (EHM). This study aims to assess potential risk factors associated with cancer development in PBC and AIH/PBC. MATERIALS AND METHODS: The Brazilian Cholestasis Study Group database was reviewed to compare clinical and laboratory features of PBC patients with HCC and EHM with those without cancer. RESULTS: Among the 752 PBC patients enrolled, 64 of them with AIH/PBC, 87 cancers were identified in 72 patients, including 20 cases of HCC and 67 of EHM. Patients with HCC had a higher prevalence of cirrhosis (95% vs. 32.5% of those subjects without cancer, p≤0.001), smoking (55% vs. 12.3%, p≤0.001), CREST syndrome (30% vs 7.6%, p=0.003) and prior azathioprine (30% vs 8%, p= 0.005) and prednisone (35% vs 14%, p= 0.018) use, whereas patients with EHM had a higher prevalence of smoking (42.3% vs 12.4% of those subjects without cancer, p= <0.001), AMA positivity (96.6% vs 80.1%, p≤0.001), azathioprine therapy (21% vs 7.9%, p= 0.01) and concurrent other autoimmune diseases. In multivariate analysis, cirrhosis, obesity and prior azathioprine therapy were independent risk factors for HCC, while Sjogren syndrome and psoriasis were associated with EHM. Fibrates reduced EHM risk. CONCLUSIONS: The prevalence of EHM is higher when compared to HCC in PBC patients. Cirrhosis, obesity, prior azathioprine use, and concurrent autoimmune diseases were significantly associated with cancer in PBC.

RESUMEN

INTRODUCTION AND OBJECTIVES: Liver stiffness measurement (LSM) by transient elastography has been validated to predict high-risk varices (HRV). We aimed to evaluate the accuracy of shear-wave elastography (SWE) and platelet count (Baveno VI criteria) to rule out HRV in patients with compensated advanced chronic liver disease (c-ACLD). METHODS: This retrospective study analyzed data of patients with c-ACLD (transient elastography ≥ 10 kPa) submitted to two-dimensional SWE (2D-SWE) (GE-LOGIQ-S8) and/or point SWE (p-SWE) (ElastPQ) who had a gastrointestinal endoscopy within 24 months. HRV definition was a large size and presence of red wale marks or sequelae from previous treatment. Optimal thresholds of SWE systems for HRV were identified. The proportion of spared gastrointestinal endoscopies and missing HRV considering a favorable SWE Baveno VI criteria were assessed. RESULTS: Eighty patients [36% male, median age = 63 (interquartile range, 57-69) years] were included. The prevalence of HRV was 34% ( n  = 27/80). The optimal thresholds to predict HRV were 10 kPa and 12 kPa for 2D-SWE and p-SWE, respectively. A favorable 2D-SWE Baveno VI criteria (LSM < 10 kPa and platelets count > 150 × 10 9 /mm 3 ) avoided 19% of gastrointestinal endoscopies without missing HRVs. A favorable p-SWE Baveno VI criteria (LSM < 12 kPa and platelets count > 150 × 10 9 /mm 3 ) spared 20% of gastrointestinal endoscopy without missing HRVs. Using a lower threshold of platelet count (<110 × 10 9 /mm 3 , expanded Baveno VI), 2D-SWE (<10 kPa) avoided 33% of gastrointestinal endoscopy with 8% of missing HRVs, while p-SWE (<12 kPa) avoided 36% of gastrointestinal endoscopy with 5% of missing HRVs. CONCLUSION: LSM by p-SWE or 2D-SWE combined with platelet count (Baveno VI criteria) can spare a considerable number of gastrointestinal endoscopies missing a negligible proportion of HRV.

RESUMEN

Cirrhosis is an emerging major cause of the development of hepatocellular carcinoma (HCC), but in non-alcoholic fatty liver disease (NAFLD), up to 50% of patients with HCC had no clinical or histological evidence of cirrhosis. It is currently challenging to propose general recommendations for screening patients with NAFLD without cirrhosis, and each patient should be evaluated on a case-by-case basis based on the profile of specific risk factors identified. For HCC screening in NAFLD, a valid precision-based screening is needed. Currently, when evaluating this population of patients, the use of non-invasive methods can guide the selection of those who should undergo a screening and surveillance program. Hence, the objective of the present study is to review the epidemiology, the pathophysiology, the histopathological aspects, the current recommendations, and novel perspectives in the surveillance of non-cirrhotic NAFLD-related HCC.

RESUMEN

INTRODUCTION AND OBJECTIVES: The Choosing Wisely (CW) initiative aims to improve daily practice supported by evidence concerning unnecessary medical tests, procedures, and treatments. This philosophy is essential in managing viral hepatitis (VH), which primary care physicians increasingly carry out. It is also essential to achieving disease elimination. Thus, the aim of our study was to propose evidence-based CW recommendations in VH. MATERIALS AND METHODS: The Brazilian Society of Hepatology (SBH) formed a panel of experts in VH who selected evidence-based CW recommendations, which were subsequently scrutinized and ranked by all members of SBH using a web-based approach. RESULTS: Five recommendations were chosen in order of importance: 1) do not order anti-HCV testing after achieving sustained virological response; 2) do not request serial HCV viral load to evaluate HCV progression, 3) do not add ribavirin to direct-acting antivirals in non-cirrhotic, naïve HCV patients; 4) do not screen for hepatocellular carcinoma in HCV patients with none to moderate fibrosis (≤ F2); 5) do not request anti-HBs after HBV vaccination, except for children born to HBV-infected mothers, hemodialysis patients, healthcare professionals, people who have had sexual contact with chronic HBV carriers, HIV-positive persons and immunocompromised individuals (hematopoietic stem-cell transplant recipients or persons receiving chemotherapy). CONCLUSIONS: CW recommendations may help general practitioners adopt a more rational and cost-effective approach in managing patients with VH in Brazil and Latin America, leading to lesser waste or harm to patients.

RESUMEN

BACKGROUND: Response to ursodeoxycholic acid (UDCA) in primary biliary cholangitis (PBC) has been traditionally assessed 1 to 2 years after treatment initiation. With the development of new drugs, some patients may benefit from an earlier introduction of second-line therapies. AIMS: This study aims to identify whether well-validated response criteria could correctly identify individuals likely to benefit from add-on second-line therapy at 6 months. METHODS: Analysis of a multicenter retrospective cohort which included only patients with clear-cut PBC. RESULTS: 206 patients with PBC (96.6% women; mean age 54 ± 12 years) were included. Kappa concordance was substantial for Toronto (0.67), Rotterdam (0.65), Paris 1 (0.63) and 2 (0.63) criteria at 6 and 12 months, whereas Barcelona (0.47) and POISE trial (0.59) criteria exhibited moderate agreement. Non-response rates to UDCA was not statistically different when assessed either at 6 or 12 months using Toronto, Rotterdam or Paris 2 criteria. Those differences were even smaller or absent in those subjects with advanced PBC. Mean baseline alkaline phosphatase was 2.73 ± 1.95 times the upper limit of normal (× ULN) among responders versus 5.05 ± 3.08 × ULN in non-responders (p < 0.001). CONCLUSIONS: After 6 months of treatment with UDCA, the absence of response by different criteria could properly identify patients who could benefit from early addition of second-line therapies, especially in patients with advanced disease or high baseline liver enzymes levels.

RESUMEN

ABSTRACT Introduction: Metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as Nonalcoholic fatty liver disease (NAFLD), is one of the most common hepatic diseases in individuals with overweight or obesity. In this context, a panel of experts from three medical societies was organized to develop an evidence-based guideline on the screening, diagnosis, treatment, and follow-up of MASLD. Material and methods: A MEDLINE search was performed to identify randomized clinical trials, meta-analyses, cohort studies, observational studies, and other relevant studies on NAFLD. In the absence of studies on a certain topic or when the quality of the study was not adequate, the opinion of experts was adopted. Classes of Recommendation and Levels of Evidence were determined using prespecified criteria. Results: Based on the literature review, 48 specific recommendations were elaborated, including 11 on screening and diagnosis, 9 on follow-up, 14 on nonpharmacologic treatment, and 14 on pharmacologic and surgical treatment. Conclusions: A literature search allowed the development of evidence-based guidelines on the screening, diagnosis, treatment, and follow-up of MASLD in individuals with overweight or obesity.
