- Hand-foot syndrome due to hepatitis C therapy(2018) CUNHA-SILVA, Marlone; MAZO, Daniel; ARRELARO, Raquel; VAZ, Nayana; RABELLO, Marcello; LOPES, Tirzah; CORREA, Barbara; TORINO, Ana Beatriz; CINTRA, Maria; LORENA, Sonia; SEVA-PEREIRA, Tiago; ALMEIDA, JazonINTRODUCTION. Direct-acting antivirals are new drugs for chronic hepatitis C treatment. They are usually safe and well tolerated, but can sometimes cause serious adverse effects and there is no consensus on how to treat or prevent them. We described a case of hand-foot syndrome due to hepatitis C virus interferon-free therapy. METHODS. We report the case of a 49-year-old man with compensated liver cirrhosis due to chronic hepatitis C genotype 1, treatment-naive, who started viral treatment with sofosbuvir, simeprevir and ribavirin for 12 weeks. RESULTS. At the sixth week of treatment he had anemia, requiring a lower dose of ribavirin. At the tenth week, he had erythematous, pruritic, scaly and flaky lesions on hands and feet, which showed a partial response to oral antihistamines and topical corticosteroids. It was not necessary to discontinue antiviral treatment, but in the first week after the end of treatment, there was worsening of injuries, including signs of secondary infection, that required hospitalization, antibiotics and oral corticosteroid, with progressive improvement. Biopsy of the lesions was consistent with pharmacodermia. The patient had sustained a virological response, despite the side effect. He had a history of pharmacodermia one year ago attributed to the use of topiramate, responsive to oral corticosteroid. CONCLUSION. Interferon-free therapies can rarely lead to severe adverse reactions, such as skin lesions. Patients receiving ribavirin combinations and those who had a history of pharmacodermia or skin disease may be more susceptible. There is no consensus on how to prevent skin reactions in these patients.
- Hepatitis E virus infection increases the risk of diabetes and severity of liver disease in patients with chronic hepatitis C virus infection(2021) ZITELLI, Patricia Momoyo Yoshimura; GOMES-GOUVEA, Michele; MAZO, Daniel F.; SINGER, Julio da Motta; OLIVEIRA, Claudia P. M. S.; FARIAS, Alberto Queiroz; PINHO, Joao Renato; TANIGAWA, Ryan Yukimatsu; ALVES, Venancio Avancini Ferreira; CARRILHO, Flair Jose; PESSOA, Mario GuimaraesOBJECTIVES: Co-infection with hepatitis A or B viruses may aggravate liver injury in patients infected with hepatitis C virus (HCV). However, few studies have assessed co-infection with hepatitis E virus (HEV) and HCV. Therefore, this study aimed to assess the prevalence and impact of HEV infection among Brazilian patients with chronic HCV infection. METHODS: This observational study included adult patients with chronic HCV infection who were naive to antiviral therapy from January 2013 to March 2016. A total of 181 patients were enrolled, and HEV serology and PCR were performed for all patients. RESULTS: Seropositivity for anti-HEV IgG was detected in 22 (12.0%) patients and anti-HEV immunoglobulin M in 3 (1.6%). HEV RNA showed inconclusive results in nine (4.9%) patients and was undetectable in the remaining patients. HEV serology positive patients had more severe liver disease, characterized by liver fibrosis >= 3 versus <= 2 (p<0.001), Aspartate Aminotransferase-to-Platelet Ratio Index of >= 1.45 (p=0.003), and Fibrosis-4 score of >= 3.25 (p=0.001). Additionally, the odds of HEV-positive patients developing diabetes mellitus were 3.65 (95% CI 1.40-9.52) times the corresponding odds of HEV-negative patients. A case-control-based histological analysis (n=11 HEV-HCV-positive patients and n=22 HCV-positive patients) showed no significant differences between the groups. CONCLUSIONS: This prevalence is higher than that reported in previous studies of the general population in Brazil. Thus, HEV infection may influence the severity of liver disease and may represent an additional risk of developing diabetes mellitus in patients with HCV infection.
- National Brazilian survey on the outcomes of hepatitis c retreatment in patients non-responders to direct antiviral agents(2022) FERRAZ, Maria Lucia Gomes; PICCOLI, Leonora de Zorzi; REZENDE, Rosamar; BORBA, Luiz Augusto; PISSAIA JUNIOR, Alcindo; CHEINQUER, Hugo; SILVA, Giovanni Faria; FERREIRA, Paulo Roberto Abrao; VILLELA-NOGUEIRA, Cristiane Alves; MAZO, Daniel Ferraz; SOUZA, Fernanda Fernandes; CODES, Liana; IVANTES, Claudia Alexandra Pontes; GOMIDE, Geisa Perez Medina; PEREIRA, Gustavo Henrique Santos; PESSOA, Mario Guimaraes; FRANCA, Alex Vianey Callado; PINTO, Arlene dos Santos; TEIXEIRA, Rosangela; BITTENCOURT, Paulo LisboaBackground and aims: Treatment of hepatitis C with direct antiviral agents (DAA) is associ-ated with almost 95% of sustained virological response. However, some patients need retreatment. In Brazil, it should be done according to the Ministry of Health guidelines, fre-quently updated to include newly available drugs. This study aimed to conduct a national survey about the characteristics and outcomes of retreatment of hepatitis C in previously non-responders to DAAs. Patients and methods: Institutions from all over the country were invited to participate in a national registry for retreatment, including information about clinical and epidemiological characteristics of the patients, type and outcomes of retreatment regimens. Only patients previously treated with interferon-free regimens were included. Results: As previous treatments the distribution was: SOF/DCV (56%), SOF/SIM (22%), 3D (11%), SOF/LED (6%) and SOF/RBV (5%). For retreatment the most frequently used drugs were SOF/GP (46%), SOF/DCV (23%) and SOF/VEL (11%). From 159 patients retreated, 132/159 (83%) had complete information in the registry and among them only seven patients were non-responders (SVR of 94.6%). All retreatments were well tolerated, without any serious adverse events or interruptions. Conclusion: The retreatment of patients previously non-responders to DAAs was associated with high rate of SVR in this sample of Brazilian patients. This finding allows us to conclude that the retreatment options available in the public health system in Brazil are effective and safe and are an important component of the strategy of elimination of hepatitis C in our country.

- Early liver function improvement following successful treatment of chronic hepatitis C in patients with decompensated cirrhosis: a real-life study(2021) LOURENCO, Mariana Sandoval; ZITELLI, Patricia Momoyo Y.; CUNHA-SILVA, Marlone; OLIVEIRA, Arthur Ivan N.; LIMA, Roque Gabriel Rezende de; OLIVEIRA, Souza Evandro de; OLIVEIRA, Claudia P.; SEVA-PEREIRA, Tiago; CARRILHO, Flair J.; PESSOA, Mario G.; MAZO, Daniel F.OBJECTIVES: Despite higher rates of sustained virologic response (SVR), important concerns remain when patients with decompensated cirrhosis due to hepatitis C virus (HCV) are treated with direct-acting antiviral agents (DAA). Questions include efficacy, safety, and the magnitude of liver function improvement. Here, we aimed to evaluate HCV treatment data in this specific population in Brazil. METHODS: We included 85 patients with decompensated cirrhosis submitted to HCV therapy with DAA followed at two academic tertiary centers in the southeastern region of Brazil. RESULTS: Seventy-nine patients (92.9%) were Child-Pugh (CP) score B, and six (7.1%) were CP score C. The mean MELD score was 12.86. The most common treatment was sofosbuvir plus daclatasvir +/- ribavirin for 24 weeks. The overall intention-to-treat (ITT) SVR rate was 87.4% (74/85) and modified-ITT 96.1% (74/77). ITT SVR was associated with lower baseline INR values (p.=0.029). Adverse events (AE) occurred in 57.9% (44/76) of patients. Serious AE were reported in 12.8% (10/78), and were related to the presence of hepatic encephalopathy (p.=0.027). SVR was associated with improvement in CP (p<0.0001) and MELD scores (p.=0.021). Among baseline CP score B patients with SVR, 46% (29/63) regressed to CP score A. Ascites was independently associated with no improvement in liver function in patients who achieved SVR (p.=0.001; OR:39.285; 95% CI:4.301-258.832). CONCLUSIONS: Patients with decompensated HCV cirrhosis showed a high SVR rate with interferon-free therapy. Early liver function improvement occurred after successful HCV eradication. However, long-term follow-up of these patients after SVR remains strongly advised.
- Changes in indications for outpatient percutaneous liver biopsy over 5 years: from hepatitis C to fatty liver disease(2022) CUNHA-SILVA, Marlone; TORRES, Luiza D.; FERNANDES, Mariana F.; SECUNDO, Tirzah De M. Lopes; MOREIRA, Marina C. G.; YAMANAKA, Ademar; MONICI, Leonardo T.; COSTA, Larissa B. Eloy da; MAZO, Daniel F.; SEVA-PEREIRA, TiagoIntroduction: Although the use of non-invasive methods for assessment of liver fibrosis has reduced the need for biopsy, the diagnosis of liver damage still requires histological evaluation in many patients. We aim to describe the indications for percutaneous liver biopsy (PLB) and the rate of complications in an outpatient setting over 5 years. Methods: This observational, single-center, and retrospective study included patients submitted to real-time ultrasound (US)-guided biopsies from 2015 to 2019. We collected age, gender, coagulation tests, comorbidities, and the number of needle passes. The association between the variables and complications was evaluated using the generalized estimating equations method. Results: We analyzed 532 biopsies in 524 patients (55.3% male) with a median age of 49 years (range 13-74y). An average of 130.3 biopsies per year were performed in the first 3 years of the study versus 70.5 in the other 2y. The main indications were hepatitis C virus (HCV) infection (47.0%), autoimmune and cholestatic liver diseases (12.6%), and metabolic dysfunction-associated fatty liver disease (MAFLD) (12.1%). The number of HCV-related biopsies had a remarkable reduction, while MAFLD-related procedures have progressively raised over time. Around 54% of the patients reported pain, which was significantly associated with females (p = 0.0143). Serious complications occurred in 11 patients (2.1%) and hospital admission was necessary in 10 cases (1.9%). No patient required surgical approach and there were no deaths. No significant association was found between the studied variables and biopsy-related complications. Conclusion: The indications for PLB in an outpatient setting have changed from HCV to MAFLDover the years. This procedure is safe and has a low rate of serious complications, but newstrategies to prevent the pain are still needed, especially for females.
- Peginterferon still has a place in the treatment of hepatitis C caused by genotype 3 virus(2017) GRANDO, Aline Vitali; FERREIRA, Paulo Roberto Abrao; PESSOA, Mario Guimaraes; MAZO, Daniel Ferraz de Campos; BRANDAO-MELLO, Carlos Eduardo; REUTER, Tania; MARTINELLI, Ana de Lourdes Candolo; GONZALEZ, Mario Peribanez; NASTRI, Ana Catharina Seixas-Santos; CAMPOS, Aleia Faustina; LOPES, Max Igor Banks Ferreira; BRITO, Jose David Urbaez; MENDES-CORREA, Maria CassiaDespite recent advances in therapy for chronic hepatitis C (CHC), the disease caused by genotype 3 virus (GEN3) is still considered a treatment challenge in certain patient subgroups. The aim of this retrospective study was to evaluate the effectiveness and safety of the peginterferon (Peg-IFN) and ribavirin (RBV) combination treatment for GEN3/CHC patients, and to evaluate sustained virological response (SVR) indicators and early treatment interruption due to serious adverse events (SAE). This was a retrospective observational study of GEN3/CHC patients, co-infected or not by HIV and treated with Peg-IFN/RBV in nine Brazilian healthcare centers. The study sample included 184 GEN3/CHC patients; 70 (38%) were co-infected with HIV. The overall SVR rate was 57.1% (95% CI 50-64). Among co-infected and mono-infected patients, the SVR rate was 51.4% (36/70) and 60.5% (69/114), respectively (p=0.241). Thirty-four (18.5%) patients experienced SAE and interrupted treatment. SVR was negatively associated with the use of Peg-IFN alpha 2b (PR 0.75; 95% CI 0.58-0.99; p=0.045) and to early treatment interruption due to SAE (PR 0.36; 95% CI 0.20-0.68; p=0.001). Early treatment interruption due to SAE was associated with age (PR 1.06; 95% CI 1.02-1.10; p<0.001) and occurrence of liver cirrhosis (PR 2.06; 95% CI 1.11-3.83; p=0.022). In conclusion, Peg-IFN/RBV might represent an adequate treatment option, mainly in young patients without advanced liver disease or when the use of direct-action drugs is limited to specific patient groups.
- Hepatitis C virus eradication improves immediate and delayed episodic memory in patients treated with interferon and ribavirin(2017) BARBOSA, Mary Ellen Dias; ZANINOTTO, Ana Luiza; MAZO, Daniel Ferraz de Campos; PESSOA, Mario Guimaraes; OLIVEIRA, Claudia Pinto Marques Souza de; CARRILHO, Flair Jose; FARIAS, Alberto QueirozBackground: Chronic hepatitis C virus (HCV) infection is associated with impairment of cognitive function and mood disorders. Our aim was to evaluate the impact of sustained virological response (SVR) on cognitive function and mood disorders. Method: A prospective exploratory one arm study was conducted. Adult clinically compensated HVC patients were consecutively recruited before treatment with interferon and ribavirin for 24 to 48 weeks, according to HCV genotype. Clinical, neurocognitive and mood assessments using the PRIME-MD and BDI instruments were performed at baseline, right after half of the expected treatment has been reached and 6 months after the end of antiviral treatment. Exclusion criteria were the use of illicit psychotropic substances, mental confusion, hepatic encephalopathy, hepatocellular carcinoma, severe anemia, untreated hypothyroidism, Addison syndrome and major depression before treatment. Results: Thirty six patients were enrolled and 21 completed HCV treatment (n = 16 with SVR and n = 5 without). Regardless of the viral clearance at the end of treatment, there was a significant improvement in the immediate verbal episodic memory (p = 0.010), delayed verbal episodic memory (p = 0.007), selective attention (p < 0.001) and phonemic fluency (p = 0.043). Patients with SVR displayed significant improvement in immediate (p = 0.045) and delayed verbal episodic memory (p = 0.040) compared to baseline. The baseline frequency of depression was 9.5%, which rose to 52.4% during treatment, and returned to 9.5% 6 months after the end of treatment, without significant difference between patients with and without SVR. Depressive symptoms were observed in 19.1% before treatment, 62% during (p = 0.016) and 28.6% 6 months after the end of treatment (p = 0.719). Conclusions: Eradication of HCV infection improved cognitive performance but did not affect the frequency of depressive symptoms at least in the short range.
