- Liver elastography can predict degree of advanced fibrosis for autoimmune hepatitis in biochemical remission(2023) PARANAGUA-VEZOZZO, Denise Cerqueira; TERRABUIO, Debora Raquel Benedita; REINOSO-PEREIRA, Gleicy Luz; MOUTINHO, Renata; ONO, Suzane Kioko; SALAS, Veronica Walwyn; FRANCA, Joao Italo Dias; ALVES, Venancio Avancini Ferreira; CANCADO, Eduardo Luiz Rachid; CARRILHO, Flair JoseBackground and AimThe aim was to analyze the concordance of liver stiffness measurement (LSM) either by transient elastography (TE) or ARFI with liver biopsy in autoimmune hepatitis (AIH) patients with biochemical remission and to identify those with histological remission. Liver biopsy is still the golden standard for AIH diagnosis. However, it is an invasive procedure and these patients, most of the time, require many biopsies, so it would be valuable to search for noninvasive method that could select all these patients and keep under observation. MethodsThirty-three patients with AIH were submitted for liver biopsy to evaluate histological remission after at least 18 months of normal aminotransferases. The efficiency of LSM and fibrosis stages was tested by a receiver operating characteristic curve analysis (AUROC). ResultsOne patient (3%) was F0, 6 (18.2%) were F1, 8 (24.2%) were F2, 10 (30.3%) were F3, and 8 (24.2%) were F4, according to METAVIR. Thirteen of thirty-three (39.4%) patients did not achieve histological remission. AUROC for F4 stage was 0.83 (IC: 0.76-0.99) for TE and 0.78 (IC: 0.65-0.95) for ARFI. Optimal LSM cutoff values were 12.3 kPa (Se = 87.5%, Sp = 88%) for TE and 1.65 m/s (Se = 87.5%, Sp = 76%) for ARFI. The tests were unable to differentiate patients with histological activity from those in histological remission (P < 0.05). ConclusionTE and ARFI accurately identify liver fibrosis by METAVIR score in AIH patients with biochemical remission. No cutoff value was detected to indicate whether the patient achieved histological remission.

- Chloroquine Is Effective for Maintenance of Remission in Autoimmune Hepatitis: Controlled, Double-Blind, Randomized Trial(2019) TERRABUIO, Debora Raquel Benedita; DINIZ, Marcio Augusto; FALCAO, Lydia Teofilo de Moraes; GUEDES, Ana Luiza Vilar; NAKANO, Larissa Akeme; EVANGELISTA, Andreia Silva; LIMA, Fabiana Roberto; ABRANTES-LEMOS, Clarice Pires; CARRILHO, Flair Jose; CANCADO, Eduardo Luiz RachidBetween 50% and 86% of patients with autoimmune hepatitis (AIH) relapse after immunosuppression withdrawal; long-term immunosuppression is associated with increased risk of neoplasias and infections. Chloroquine diphosphate (CQ) is an immunomodulatory drug that reduces the risk of flares in rheumatologic diseases. Our aims were to investigate the efficacy and safety of CQ for maintenance of biochemical remission of AIH in a double-blind randomized trial and to define a subgroup that obtained a greater benefit from its use. A total of 61 patients with AIH in histologic remission (90.1% AIH type 1 [AIH-1]) were randomized to receive CQ 250 mg/day or placebo for 36 months. Of the 61 patients, 31 received CQ and 30 placebo. At baseline, clinical, laboratory, histologic findings, and human leukocyte antigen (HLA) profile were similar between the two groups. Relapse-free survival was significantly higher in the CQ group compared to the placebo group (59.3% and 19.9%, respectively P = 0.039). For those patients completing 3-year treatment, relapse rates were 41.6% and 0% after CQ and placebo withdrawal, respectively. Factors associated with a higher risk of relapse in multiple Cox regression were placebo use (hazard ratio, 2.4; 95% confidence interval [CI], 1.055.5; P = 0.039) and anti-soluble liver antigen/liver-pancreas (anti-SLA/LP) seropositivity (hazard ratio, 5.4; 95% CI, 1.91-15.3; P = 0.002). Although it was not possible to define a subgroup that obtained a greater benefit from CQ according to anti-SLA/LP reactivity or HLA profile, 100% of patients who were anti-SLA/LP-positive (+) relapsed with placebo compared to 50% with CQ (P = 0.055). In the CQgroup, 54.8% had side effects and 19.3% interrupted the drug regimen. Conclusion: CQ safely reduced the risk of relapse of AIH, but it was not possible to define a subgroup that obtained a greater benefit with CQ use, probably because of sample size.

This exploratory study aims to evaluate the long-term real-life biochemical response of different fibrates, including ciprofibrate, in subjects with UDCA-unresponsive PBC.Methods: The Brazilian Cholestasis Study Group multicenter database was reviewed to assess the response rates to UDCA plus fibrates in patients with UDCA-unresponsive PBC 1 and 2 years after treatment initiation by different validated criteria.Results: In total, 27 patients (100% women, mean age 48.9 +/- 9.2 years) with PBC were included. Overall response rates to fibrates by each validated criterion varied from 39 to 60% and 39-76% at 12 and 24 months after treatment combination, respectively. Combination therapy resulted in a significant decrease in ALT and ALP only after 2 years, while GGT significantly improved in the first year of treatment. Treatment response rates at 1 and 2 years appear to be comparable between ciprofibrate and bezafibrate using all available criteria.Conclusion: Our findings endorse the efficacy of fibrate add-on treatment in PBC patients with suboptimal response to UDCA. Ciprofibrate appears to be at least as effective as bezafibrate and should be assessed in large clinical trials as a possibly new, cheaper, and promising option for treatment of UDCA-unresponsive PBC patients.
- Response to Ursodeoxycholic Acid May Be Assessed Earlier to Allow Second-Line Therapy in Patients with Unresponsive Primary Biliary Cholangitis(2023) CANCADO, Guilherme Grossi Lopes; COUTO, Claudia Alves; TERRABUIO, Debora Raquel Benedita; CANCADO, Eduardo Luiz Rachid; VILLELA-NOGUEIRA, Cristiane Alves; FERRAZ, Maria Lucia Gomes; BRAGA, Michelle Harriz; NARDELLI, Mateus Jorge; FARIA, Luciana Costa; GOMES, Nathalia Mota de Faria; OLIVEIRA, Elze Maria Gomes; ROTMAN, Vivian; OLIVEIRA, Maria Beatriz; CUNHA, Simone Muniz Carvalho Fernandes da; CUNHA-SILVA, Marlone; MENDES, Liliana Sampaio Costa; IVANTES, Claudia Alexandra Pontes; CODES, Liana; BORGES, Valeria Ferreira de Almeida E; PACE, Fabio Heleno de Lima; PESSOA, Mario Guimaraes; GUEDES, Laura Vilar; SIGNORELLI, Izabelle Venturini; CORAL, Gabriela Perdomo; LEVY, Cynthia; BITTENCOURT, Paulo LisboaBackground 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 (x ULN) among responders versus 5.05 +/- 3.08 x 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.
- Risk factors for cancer in patients with primary biliary cholangitis and autoimmune hepatitis and primary biliary cholangitis overlap syndrome(2023) BRAGA, Michelle Harriz; CANCADO, Guilherme Grossi Lopes; BITTENCOURT, Paulo Lisboa; COUTO, Claudia Alves; GUEDES, Laura Vilar; LIMA, Andre Mourao Costa; FERRAZ, Maria Lucia Gomes; VILLELA-NOGUEIRA, Cristiane Alves; NARDELLI, Mateus Jorge; FARIA, Luciana Costa; GOMES, Nathalia Mota de Faria; OLIVEIRA, Elze Maria Gomes; ROTMAN, Vivian; OLIVEIRA, Maria Beatriz; CUNHA, Simone Muniz Carvalho Fernandes da; CUNHA-SILVA, Marlone; MENDES, Liliana Sampaio Costa; IVANTES, Claudia Alexandra Pontes; CODES, Liana; BORGES, Valeria Ferreira de Almeida e; PACE, Fabio Heleno de Lima; PESSOA, Mario Guimaraes; SIGNORELLI, Izabelle Venturini; CORAL, Gabriela Perdomo; GALIZZI FILHO, Joao; CHAGAS, Aline Lopes; TERRABUIO, Debora Raquel Benedita; CANCADO, Eduardo Luiz RachidIntroduction and objectives: Primary biliary cholangitis (PBC) and autoimmune hepatitis (AIH) and PBC over-lap 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
conferenceObject Stanozolol-induced liver injury: a peculiar biochemical profile in a series of thirteen cases(2023) NUNES, Vinicius; ALMEIDA, Isadora; CAMPOS, Maria Carolina; FREIRE, Barbara; SILVA, Marcelo; PARANA FILHO, Raymundo; BESSONE, Fernando; HERNANDEZ, Nelia; CANCADO, Eduardo; SCHINONI, Maria- Humoral autoimmune response heterogeneity in the spectrum of primary biliary cirrhosis(2013) DELLAVANCE, Alessandra; CANCADO, Eduardo Luiz R.; ABRANTES-LEMOS, Clarice Pires; HARRIZ, Michelle; MARVULLE, Valdecir; ANDRADE, Luis Eduardo C.To compare autoantibody features in patients with primary biliary cirrhosis (PBC) and individuals presenting antimitochondria antibodies (AMAs) but no clinical or biochemical evidence of disease. A total of 212 AMA-positive serum samples were classified into four groups: PBC (definite PBC, n = 93); PBC/autoimmune disease (AID; PBC plus other AID, n = 37); biochemically normal (BN) individuals (n = 61); and BN/AID (BN plus other AID, n = 21). Samples were tested by indirect immunofluorescence (IIF) on rat kidney (IIF-AMA) and ELISA [antibodies to pyruvate dehydrogenase E2-complex (PDC-E2), gp-210, Sp-100, and CENP-A/B]. AMA isotype was determined by IIF-AMA. Affinity of anti-PDC-E2 IgG was determined by 8 M urea-modified ELISA. High-titer IIF-AMA was more frequent in PBC and PBC/AID (57 and 70 %) than in BN and BN/AID samples (23 and 19 %) (p < 0.001). Triple isotype IIF-AMA (IgA/IgM/IgG) was more frequent in PBC and PBC/AID samples (35 and 43 %) than in BN sample (18 %; p = 0.008; p = 0.013, respectively). Anti-PDC-E2 levels were higher in PBC (mean 3.82; 95 % CI 3.36-4.29) and PBC/AID samples (3.89; 3.15-4.63) than in BN (2.43; 1.92-2.94) and BN/AID samples (2.52; 1.54-3.50) (p < 0.001). Anti-PDC-E2 avidity was higher in PBC (mean 64.5 %; 95 % CI 57.5-71.5 %) and PBC/AID samples (66.1 %; 54.4-77.8 %) than in BN samples (39.2 %; 30.9-37.5 %) (p < 0.001). PBC and PBC/AID recognized more cell domains (mitochondria, nuclear envelope, PML/sp-100 bodies, centromere) than BN (p = 0.008) and BN/AID samples (p = 0.002). Three variables were independently associated with established PBC: high-avidity anti-PDC-E2 (OR 4.121; 95 % CI 2.118-8.019); high-titer IIF-AMA (OR 4.890; 2.319-10.314); antibodies to three or more antigenic cell domains (OR 9.414; 1.924-46.060). The autoantibody profile was quantitatively and qualitatively more robust in definite PBC as compared with AMA-positive biochemically normal individuals.
