- Anti-mitochondrial Antibody-Negative Primary Biliary Cholangitis Is Part of the Same Spectrum of Classical Primary Biliary Cholangitis(2022) CANCADO, Guilherme Grossi Lopes; BRAGA, Michelle Harriz; FERRAZ, Maria Lucia Gomes; VILLELA-NOGUEIRA, Cristiane Alves; TERRABUIO, Debora Raquel Benedita; CANCADO, Eduardo Luiz Rachid; 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; PACE, Fabio Heleno de Lima; PESSOA, Mario Guimaraes; SIGNORELLI, Izabelle Venturini; CORAL, Gabriela Perdomo; BITTENCOURT, Paulo Lisboa; LEVY, Cynthia; COUTO, Claudia AlvesBackground Primary biliary cholangitis (PBC) is a chronic cholestatic liver disease in which anti-mitochondrial antibodies (AMA) are the diagnostic hallmark. Whether AMA-negative PBC patients represent a different phenotype of disease is highly debated. Aims The purpose of our study was to compare AMA-positive and AMA-negative PBC patients in a large non-white admixed Brazilian cohort. Methods The Brazilian Cholestasis Study Group multicentre database was reviewed to assess demographics, clinical features and treatment outcomes of Brazilian PBC patients, stratifying data according to AMA status. Results A total of 464 subjects (95.4% females, mean age 56 +/- 5 years) with PBC were included. Three hundred and eighty-four (83%) subjects were AMA-positive, whereas 80 (17%) had AMA-negative PBC. Subjects with AMA-negative PBC were significantly younger (52.2 +/- 14 vs. 59.6 +/- 11 years, p = 0.001) and had their first symptom at an earlier age (43.2 +/- 13 vs. 49.5 +/- 12 years, p = 0.005). Frequency of type 2 diabetes was significantly increased in subjects with AMA-negative PBC (22.5% vs. 12.2%, p = 0.03). Lower IgM (272.2 +/- 183 vs. 383.2 +/- 378 mg/dL, p = 0.01) and triglycerides (107.6 +/- 59.8 vs.129.3 +/- 75.7 mg/dL, p = 0.025) and higher bilirubin (3.8 +/- 13.5 vs. 1.8 +/- 3.4 mg/dL, p = 0.02) levels were also observed in this subgroup. Response to ursodeoxycholic acid varied from 40.5 to 63.3% in AMA-positive and 34 to 62.3% in AMA-negative individuals, according to different response criteria. Outcomes such as development of liver-related complications, death and requirement for liver transplantation were similar in both groups. Conclusions AMA-negative PBC patients are similar to their AMA-positive counterparts with subtle differences observed in clinical and laboratory features.
- HLA-related genetic susceptibility in autoimmune hepatitis according to autoantibody profile(2022) CANCADO, Eduardo Luiz Rachid; GOLDBAUM-CRESCENTE, Juliana; TERRABUIO, Debora Raquel B.Although the prevalence of autoimmune hepatitis in first-degree relatives is small, the relationship between genetic markers, especially human leucocyte antigens (HLA), and susceptibility to this disease, has been studied for over three decades. The genetic susceptibility to AIH is believed to be different in the two subtypes of the disease, AIH type 1 and AIH type 2. Type 1 AIH has anti-smooth muscle and anti-nuclear antibodies as its main markers, while those of type 2 AIH are the anti-liver/kidney microsome type 1 and anti-liver cytosol type 1 antibodies. The anti-soluble liver antigen/liver-pancreas antibodies, which, in addition to being present in both subtypes, mark an important number of patients without serological markers. Therefore, a third type of disease is questionable. The vast majority of immunogenetic studies compare the differences between the two main types and make no difference between which antibodies are present to define the subtype. This review seeks to analyze what was most important published in the AIH in this context, trying to relate the HLA alleles according to the AIH marker autoantibodies.
- Primary Adrenal Insufficiency Due to Bilateral Adrenal Infarction in COVID-19(2022) MACHADO, Iza F. R.; MENEZES, Isabel Q.; FIGUEIREDO, Sabrina R.; COELHO, Fernando M. A.; TERRABUIO, Debora R. B.; V, Davi Ramos; FAGUNDES, Gustavo F. C.; MACIEL, Ana Alice W.; LATRONICO, Ana Claudia; V, Maria Candida B. Fragoso; CANCADO, Eduardo L. R.; MENDONCA, Berenice B.; ALMEIDA, Madson Q.Context: Coronavirus disease 2019 (COVID-19) is a proinflammatory and prothrombotic condition, but its impact on adrenal function has not been adequately evaluated. Case report: A 46-year-old woman presented with abdominal pain, hypotension, and skin hyperpigmentation after COVID-19 infection. The patient had hyponatremia, serum cortisol <1.0 mu g/dL, adrenocorticotropin (ACTH) of 807 pg/mL, and aldosterone <3 ng/dL. Computed tomography (CT) findings of adrenal enlargement with no parenchymal and minimal peripheral capsular enhancement after contrast were consistent with bilateral adrenal infarction. The patient had autoimmune hepatitis and positive antiphospholipid antibodies, but no previous thrombotic events. The patient was treated with intravenous hydrocortisone, followed by oral hydrocortisone and fludrocortisone. Discussion: We identified 9 articles, including case reports, of new-onset adrenal insufficiency and/or adrenal hemorrhage/infarction on CT in COVID-19. Adrenal insufficiency was hormonally diagnosed in 5 cases, but ACTH levels were measured in only 3 cases (high in 1 case and normal/low in other 2 cases). Bilateral adrenal nonhemorrhagic or hemorrhagic infarction was identified in 5 reports (2 had adrenal insufficiency, 2 had normal cortisol levels, and 1 case had no data). Interestingly, the only case with well-characterized new-onset acute primary adrenal insufficiency after COVID-19 had a previous diagnosis of antiphospholipid syndrome. In our case, antiphospholipid syndrome diagnosis was established only after the adrenal infarction triggered by COVID-19. Conclusion: Our findings support the association between bilateral adrenal infarction and antiphospholipid syndrome triggered by COVID-19. Therefore, patients with positive antiphospholipid antibodies should be closely monitored for symptoms or signs of acute adrenal insufficiency during COVID-19.
- Fibrates for the Treatment of Primary Biliary Cholangitis Unresponsive to Ursodeoxycholic Acid: An Exploratory Study(2022) CANCADO, Guilherme Grossi Lopes; COUTO, Claudia Alves; GUEDES, Laura Vilar; BRAGA, Michelle Harriz; TERRABUIO, Debora Raquel Benedita; CANCADO, Eduardo Luiz Rachid; FERRAZ, Maria Lucia Gomes; VILLELA-NOGUEIRA, Cristiane Alves; NARDELLI, Mateus Jorge; FARIA, Luciana Costa; OLIVEIRA, Elze Maria Gomes de; ROTMAN, Vivian; MAZO, Daniel Ferraz de Campos; BORGES, Valeria Ferreira de Almeida e; MENDES, Liliana Sampaio Costa; CODES, Liana; PESSOA, Mario Guimaraes; SIGNORELLI, Izabelle Venturini; LEVY, Cynthia; BITTENCOURT, Paulo LisboaAim: Up to 40% of patients with primary biliary cholangitis (PBC) will have a suboptimal biochemical response to ursodeoxycholic acid (UDCA), which can be improved by the addition of fibrates. 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.
- Clinical features and treatment outcomes of primary biliary cholangitis in a highly admixed population(2022) CANCADO, Guilherme Grossi Lopes; BRAGA, Michelle Harriz; FERRAZ, Maria Lucia Gomes; VILLELA-NOGUEIRA, Cristiane Alves; TERRABUIO, Debora Raquel Benedita; CANCADO, Eduardo Luiz Rachid; NARDELLI, Mateus Jorge; FARIA, Luciana Costa; GOMES, Nathalia Mota de Faria; OLIVEIRA, Elze Maria Gomes de; ROTMAN, Vivian; OLIVEIRA, Maria Beatriz de; CUNHA, Simone Muniz Carvalho Fernandes da; MAZO, Daniel Ferraz de Campos; 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; BITTENCOURT, Paulo Lisboa; LEVY, Cynthia; COUTO, Claudia AlvesIntroduction and objectives: Little is known about primary biliary cholangitis (PBC) in non-whites. The purpose of this study was to evaluate clinical features and outcomes of PBC in a highly admixed population. Material and methods: The Brazilian Cholestasis Study Group multicentre database was reviewed to assess demographics, clinical features and treatment outcomes of Brazilian patients with PBC. Results: 562 patients (95% females, mean age 51 +/- 11 years) with PBC were included. Concurrent autoimmune diseases and overlap with autoimmune hepatitis (AIH) occurred, respectively, in 18.9% and 14%. After a mean follow-up was 6.2 +/- 5.3 years, 32% had cirrhosis, 7% underwent liver transplantation and 3% died of liver-related causes. 96% were treated with ursodeoxycholic acid (UDCA) and 12% required add-on therapy with fibrates, either bezafibrate, fenofibrate or ciprofibrate. Response to UDCA and to UDCA/fibrates therapy varied from 39%-67% and 42-61%, respectively, according to different validated criteria. Advanced histologi -cal stages and non-adherence to treatment were associated with primary non-response to UDCA, while lower baseline alkaline phosphatase (ALP) and aspartate aminotransferase (AST) levels correlated with better responses to both UDCA and UDCA/fibrates. Conclusions: Clinical features of PBC in highly admixed Brazilians were similar to those reported in Cauca-sians and Asians, but with inferior rates of overlap syndrome with AIH. Response to UDCA was lower than expected and inversely associated with histological stage and baseline AST and ALP levels. Most of patients benefited from add-on fibrates, including ciprofibrate. A huge heterogeneity in response to UDCA therapy according to available international criteria was observed and reinforces the need of global standardization.
