RESUMO

AIM: This multicenter field-practice study evaluates outcomes of long-term sorafenib in hepatocellular carcinoma (HCC) patients. METHODS: Consecutive HCC patients on sorafenib were enrolled. We evaluated those receiving sorafenib for ≥12 months. RESULTS: Out of 800 patients on sorafenib, 81 (10%) received long-term treatment. Median duration of treatment was 22.7 months (range: 12.3-92.6). Only 21 (26%) reported grade 3/4 adverse events. Complete response was reported in 11 patients (14%). Median overall survival was 34.8 months (95% CI: 29.9-44.3). Only baseline Child-Pugh class was associated with survival. CONCLUSION: Sorafenib could result in long-term control of HCC in a relevant proportion of patients. Given the availability of regorafenib in the second-line setting, an earlier introduction of systemic therapy may be considered according to clinical indications.

RESUMO

PURPOSE: To compare short- and long-term clinical outcomes after conventional transarterial chemoembolization and drug-eluting bead (DEB) transarterial chemoembolization in hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Patients with unresectable HCC unsuitable for ablative therapies were randomly assigned to undergo conventional or DEB chemoembolization. The primary endpoints of the study were safety, toxicity, and tumor response at 1 month. Secondary endpoints were number of repeated chemoembolization cycles, time to recurrence and local recurrence, time to radiologic progression, and survival. RESULTS: In total, 67 patients (mean age, 70 y ± 7.7) were evaluated. Mean follow-up was 816 days ± 361. Two periprocedural major complications occurred (2.9%) that were treated by medical therapy without the need for other interventions. A significant increase in alanine aminotransferase levels 24 hours after treatment was reported, which was significantly greater after conventional chemoembolization (n = 34) than after DEB chemoembolization (n = 33; preprocedure, 60 IU ± 44 vs 74 IU ± 62, respectively; at 24 h, 216 IU ± 201 vs 101 IU ± 89, respectively; P = 0.007). No other differences were observed in liver toxicity between groups. At 1 month, complete and partial tumor response rates were 70.6% and 29.4%, respectively, in the conventional chemoembolization group and 51.5% and 48.5%, respectively, in the DEB chemoembolization group. No differences were observed between groups in time to recurrence and local recurrence, radiologic progression, and survival. CONCLUSIONS: Conventional chemoembolization and DEB chemoembolization have a limited impact on liver function on short- and long-term follow-up and are associated with favorable clinical outcomes.

RESUMO

BACKGROUND: Hepatocellular carcinoma (HCC) is the fifth most common neoplasia in the world. In the past, treatment of advanced HCC with conventional antineoplastic drugs did not result in satisfactory outcomes: recently, in this patient population the oral multikinase inhibitor sorafenib has been able to induce a statistically significant improvement of overall survival. Similarly to other anti-angiogenic drugs employed in other tumour types, also sorafenib seldom induces the dimensional tumour shrinking usually observed with conventional cytotoxic drugs: data gathered from studies carried out with sorafenib and other competitors under development do not report any complete response in HCV-induced HCC. CASE PRESENTATION: An 84-year old man with a long-lasting history of chronic HCV hepatitis was referred to our Institution for an ultrasonography investigation of a focal hepatic lesion. To better characterize the liver disease and clearly define the diagnosis of the focal hepatic lesion, the patient was hospitalized in our department. Laboratory and instrumental investigations confirmed the clinical picture of HCV-related liver cirrhosis and identified a hepatic lesion of about 6 cm featuring infiltrating HCC with thrombosis of the portal trunk. Due to the advanced stage of the disease, therapy with sorafenib 400 mg bid was started. Right from one month after the treatment was started, a reduction of alpha-fetoprotein level was observed which, by the third month, turned down within the normal limits. In addition the CT scan showed 50% reduction of the neoplastic lesion along with canalization of the portal trunk. At the sixth month the normalization of the alpha-fetoprotein level at the lower limit of normality was confirmed and the MRI showed complete disappearance of the neoplasia. In addition a reduction of a metallo-proteinase serum level was observed. At the twelfth month a further MRI confirmed complete response had been maintained. At present the patient is in a follow-up program to evaluate the duration of the complete response. CONCLUSIONS: This case is worth mentioning since, to the best of our knowledge, it represents the first evidence of complete response to sorafenib in an elderly patient with advanced HCV-related HCC.

RESUMO

Leukocytes are thought to play an important role in the pathogenesis of inflammatory bowel diseases; granulocyte-monocyte adsorptive (GMA) apheresis, an extracorporeal technique aimed at removing activated circulating leukocytes from the blood, may represent a safe and effective therapeutic tool in these patients. The Italian Registry of Therapeutic Apheresis performed an observational, multicentric study involving 24 Gastroenterology Units. In this study, laboratory data and clinical outcomes of 230 patients (148 males, mean age 43.5 years) affected with ulcerative colitis (UC, n = 194) or Crohn's disease (CD, n = 36) who underwent one or more cycles of GMA were analyzed. Each cycle consisted of five GMA treatments. The patients were followed up for a mean of 8.7 (min. 3 to max. 12) months. At 3 months, positive outcome was achieved in 77.7% of UC patients (72.0% remission, 5.7% clinical response) and 61.3% of CD patients (54.8% remission, 6.5% clinical response). The cumulative proportion of positive outcome at 12 months was 87.1% for UC patients (83.7% remission, 3.4% clinical response) and 77.4% for CD patients (74.2% remission, 3.2% clinical response). No single clinical or laboratory parameter among those analyzed (age, sex, disease characteristics, history of smoking, medication history, baseline values of clinical activity index (CAI)/Crohn's disease activity index (CDAI), hemoglobin, white blood cells count, and erythrocyte sedimentation rate) was independently associated with clinical outcome. The procedure was well tolerated with no significant adverse effects registered.

RESUMO

Chronic hepatitis B virus (HBV) infection is a global health problem and has an increased prevalence in patients with Crohn's disease due to their increased requirement for high-risk procedures. A balance between viral replication and host immune response exists and drugs such as the immunosuppressive agents used to treat Crohn's disease may alter this balance. These may result in a hepatic flare, which manifests as high viremia, increased transaminase levels, and hepatic decompensation. The present study describes two cases of hepatic flare thought to be caused by treatment of acute Crohn's disease with systemic corticosteroids and/or azathioprine. Both patients presented with raised transaminase and gamma glutamyl transferase levels and viremia. One patient experienced a decrease in hepatic function, as evidenced by a reduced serum albumin (2.5g/ dL) and jaundice (total bilirubin 5.2 mg/dL), and hepatic decompensation, with ascites. Both patients were treated with the nucleoside analogue entecavir 0.5 mg/day and experienced reductions in HBV-DNA and hepatic enzyme levels within 4-7 days. The patient with decompensation received diuretic therapy and parenteral nutrition to support hepatic function and a clinical improvement was seen. Both patients were discharged 2 weeks after admission and, during follow-up, HBV-DNA levels became negative after 1 and 5 months, respectively. No adverse events were reported in either patient. To the best of our knowledge, this is the first documented report of treatment of HBV flare with entecavir in patients co-affected with Crohn's disease.

RESUMO

BACKGROUND: The once-daily oral combination of daclatasvir (DCV) and sofosbuvir (SOF), with or without ribavirin (RBV), is effective and well tolerated in patients with hepatitis C virus (HCV). However, further field-practice studies are necessary to investigate the effectiveness and safety of the DCV+SOF combination in diverse subpopulations of patients with HCV, including those who are more challenging to treat such as patients with a genotype 3 (G3) infection. The aim of this retrospective, multicenter, field-practice study was to investigate the therapeutic efficacy and safety of the oral combination of DCV and SOF, with or without RBV (DCV+SOF±RBV), in a large unselected cohort of patients with chronic HCV infection (CHC). PATIENTS AND METHODS: Consecutive patients received DCV+SOF±RBV for 12 or 24 weeks. The efficacy endpoint was sustained virological response at 12 weeks after the end of treatment (SVR12). Safety factors were also considered. RESULTS: A total of 620 patients were included in this study; the predominant genotype was G3 (55.3%). Of the total sample, 248 (40%) patients were treated with DCV+SOF+RBV and 372 (60%) did not receive RBV. The majority of patients assessed at week 12 (98%, 596/608) achieved SVR12. Among G3 patients, 98.8% (335/339) achieved SVR12. The most common adverse event was elevated bilirubin (30.6%), recorded in 4.9% of cases as a grade 3-4 adverse event. CONCLUSION: This study shows the high pan-genotypic effectiveness and safety of the DCV+SOF±RBV combination in a large, unselected sample of CHC patients with G1-4, including a wide proportion of G3 CHC patients.

RESUMO

BACKGROUND: Recent introduction of direct antiviral agents (DAAs) has completely changed the scenario regarding hepatitis C virus (HCV) treatment. Certain countries' economic health programs prioritize DAAs according to specific clinical features of HCV-infected patients. The aim of this study was to define epidemiological, demographic and clinical characteristics of HCV-infected patients in the Tuscany region of central Italy. METHODS: We enrolled HCV patients with chronic viral hepatitis who were referred to the outpatient services of 16 hospitals in Tuscany from 1 January 2015 to 31 December 2015. Case report forms contained patient information including main demographic data, blood chemistry data, viral hepatitis markers, instrumental evaluations (liver biopsy or transient elastometry, liver ultrasound), eligibility for DAAs, and liver transplantation or therapy already in progress. RESULTS: Of all patients considered, 2919 HCV patients were enrolled (mean age: 57.44 ± 15.15; 54% males, 46% females). All routes of transmission were well represented (intravenous drug use in 20.7%; nosocomial/dental care in 20.6%; and coagulation factors/blood transfusions in 13.3%). Diabetes was the highest represented comorbidity (20.8%), followed by metabolic syndrome (15.5%) and ischemic heart disease (6.2%). The most prevalent HCV genotypes were 1b (47.4%) and 2 (16.5%). In the whole cohort of patients, 32.8% were cirrhotic (40 patients were listed for liver transplantation). Signs of portal hypertension were present mostly in the group older than 45 years (92.3%). Extrahepatic HCV-related diseases were present in 13.3% of cases (cryoglobulinemic syndrome in 58.3% and B-cell non-Hodgkin's lymphoma in 10.5%). CONCLUSIONS: Our study provides evidence of a high prevalence of epidemiological changes in HCV infection with a major prevalence of advanced liver disease, such as portal hypertension, in this elderly cohort of patients.

RESUMO

AIM: To evaluate granulocytapheresis (GCAP) in active ulcerative colitis (UC), with particular attention to the long-term effects of such treatment. METHODS: We included 80 patients with UC. Activity of the disease was evaluated by clinical activity index and endoscopic index. Patients were randomly divided in two groups: Group A received a five-session (1 session/week) treatment with GCAP, Group B were treated with i.v. or i.m. methylprednisolone (MP). Concomitant therapy with oral 5-aminosalicylic acid (5-ASA) 2.4 g/day was maintained in both groups. Subjects who achieved a remission were clinically and endoscopically followed for 12 months after the end of GCAP or MP. RESULTS: Remission was observed in 72.5% of those treated with GCAP versus 50% of those treated with MP. After a 12-month follow up, a sustained remission was recorded in 40% of those treated with GCAP and in 25% of those treated with MP. During the GCAP only a transient mild headache was recorded in 10% of patients, whereas side-effects were observed in 50% of those treated with MP (P < 0.05). CONCLUSION: GCAP results were superior to MP for the treatment of UC, even though no statistically significant difference was observed. Side-effects in the GCAP group were significantly lower than in the MP group. This new therapeutic approach seems able to maintain the condition of remission for a longer time after a flare. In fact, the patients who had obtained a remission after a course of CGAP showed fewer relapses during the follow up compared to the patients treated with MP.

RESUMO

AIM: To build a regional database of chronic patients to define the clinical epidemiology of hepatitis B virus (HBV)-infected patients in the Tuscan public health care system. METHODS: This study used a cross-sectional cohort design. We evaluated chronic viral hepatitis patients with HBV referred to the outpatient services of 16 hospital units. Information in the case report forms included main demographic data, blood chemistry data, viral hepatitis markers, instrumental evaluations, and eligibility for treatment or ongoing therapy and liver transplantation. RESULTS: Of 4015 chronic viral hepatitis patients, 1096 (27.3%) were HBV infected. The case report form was correctly completed for only 833 patients (64% males, 36% females; mean age 50.1 ± 15.4). Of these HBV-infected patients, 73% were Caucasian, 21% Asian, 4% Central African, 1% North African and 1% American. Stratifying patients by age and nationality, we found that 21.7% of HBV-infected patients were aged < 34 years (only 2.8% were Italian). The most represented routes of transmission were nosocomial/dental procedures (23%), mother-to-child (17%) and sexual transmission (12%). The most represented HBV genotypes were D (72%) and A (14%). Of the patients, 24.7% of patients were HBeAg positive, and 75.3% were HBeAg negative. Of the HBV patients 7% were anti-HDV positive. In the whole cohort, 26.9% were cirrhotic (35.8% aged < 45 years), and 47% were eligible for or currently undergoing treatment, of whom 41.9 % were cirrhotic. CONCLUSION: Only 27.3% of chronic viral hepatitis patients were HBV infected. Our results provide evidence of HBV infection in people aged < 34 years, especially in the foreign population not protected by vaccination. In our cohort of patients, liver cirrhosis was also found in young adults.

RESUMO

According to the current European Association for the Study of Liver guidelines, transarterial chemoembolization (TACE) is the recommended first-line therapy for patients with intermediate-stage (Barcelona Clinic Liver Cancer-B class) hepatocellular carcinoma (HCC). The efficacy of this therapy is supported by robust evidence; however, there is still a lack of standardization in treatment methodology, and TACE protocols are widely variable. Moreover, TACE can be associated with a number of contraindications. Despite these limitations, research on TACE is still ongoing with the aim of optimizing the use of this methodology in the current management of HCC. In particular, TACE represents a control in comparative studies, and it is currently being investigated in combination schemes, for example, with sorafenib. In this review, we briefly describe the current scenario and the clinical innovations regarding TACE for the treatment of HCC.

RESUMO

BACKGROUND AND AIMS: Helicobacter pylori (H. pylori) eradication in patients who failed one or more therapeutic attempts remains challenging. This study aimed to assess the efficacy of three-in-one capsules bismuth-based quadruple therapy (Pylera®) in these patients managed in clinical practice. METHODS: This was a prospective, open-label, multicenter study enrolling consecutive, adult patients with persistent H. pylori infection following at least one standard therapy. All patients received a rescue quadruple therapy with Pylera (3 capsules four times daily) and esomeprazole 20 mg (1 tablet twice daily) for 10 days. H. pylori eradication was assessed by using Urea Breath Test 4-6 weeks following therapy ending. H. pylori eradication rates, compliance, and side-effects were calculated. RESULTS: A total of 208 patients in the 9 participating centres were enrolled. Overall, 180 patients were successfully cured from the infection, accounting for 86.5% (95% CI 81.9-91.2) and 92.3% (95% CI 88.6-96.1) eradication rates at intention-to-treat analysis and at per protocol analysis, respectively. Cure rates were similar across patients who failed one to three previous therapy attempts, but the success rate fell to 67% after 4 or more therapy failures. Compliance to therapy was good in 198 (95.2%) patients, whilst in 7 (5.3%) cases the therapy was interrupted within 5 days due to side effects. A total of 97 (46.6%) patients complained of at least one side effect; nausea, diarrhea and vomiting were the most frequently reported. CONCLUSIONS: Our study found that this bismuth-based quadruple therapy is highly effective as second-line and rescue therapy for H. pylori eradication in clinical practice.

RESUMO

Hepatocellular carcinoma (HCC) is the most common type of liver cancer and is the second cause of death due to malignancy in the world. The treatment of HCC is complex and includes potentially curative and palliative approaches. However, both curative and palliative treatments for HCC are often associated with a not-completely favorable safety/efficacy ratio. Therefore, other treatment options appear necessary in clinical practice. Transarterial radioembolization has shown a promising efficacy in terms of disease control and is associated with a good safety profile. This review discusses the use of transarterial radioembolization in HCC, with a focus on the clinical aspects of this therapeutic strategy.

RESUMO

BACKGROUND: We report our preliminary experience with the use of video capsule endoscopy (VCE) in 64 patients with obscure gastrointestinal bleeding (OGIB) and suspected small intestine disease. METHODS: To be eligible for VCE, patients had to have undergone upper endoscopy, small bowel series, and colonscopy without discovering any source of bleeding. To find the best timing to perform VCE, the patients were retrospectively divided in two groups of 32 cases each: group 1 with patients who had been submitted to VCE within 15 days from OGIB diagnosis, and group 2 with patients who had been submitted to VCE at least 15 days after OGIB diagnosis. RESULTS: Lesions were found by VCE in 29 (91%) in group 1: angioectasia-like lesions of the small bowel in 12, some erosions of the ileum without signs of bleeding in 14, a polyp with erosions in 1, and a bleeding site where the surgery showed a tumor of the ileum in 2 patients. In 2 cases, VCE missed showing two small tumors that were revealed by laparoscopy in 1 case and by push enteroscopy in the other. In group 2, lesions were found by VCE in 11 (34%): angioectasia-like lesions of the small bowel in 6, some erosions in 3, a short segmental stenosis in 1, and two polyps in 1. In 1 case, VCE missed showing a small polyp in the jejunum that was revealed by push enteroscopy. In none of these cases was a bleeding site identified. VCE was well tolerated and able to acquire good images in patients with OGIB. It showed lesions in 91% of the patients in group 1 and 34% of cases in group 2. CONCLUSIONS: Our data suggest that the optimal timing to perform VCE is within a few days after the occurrence of bleeding, possibly within 2 weeks.

RESUMO

Cytokines such as TNF-α have a validated role in the immunopathogensis of ulcerative colitis (UC), and intercepting inflammatory cytokines is currently the best option for maximizing treatment efficacy. One of the major sources of inflammatory cytokines are myeloid linage leucocytes (granulocytes, monocytes), which are present in great numbers in the colonic tissue. Their selective depletion by adsorptive granulocyte, monocyte apheresis (GMA), should be therapeutic in patients with UC, although until now efficacy outcomes have been both encouraging and disappointing. The authors' view is that in patients with UC, there is an evolving scope for therapeutic opportunity based on taking away the sources of inflammatory cytokines, also considering the favorable safety profile of GMA.

RESUMO

BACKGROUND: Lactate dehydrogenase (LDH) is a predictor of clinical outcome in hepatocellular carcinoma (HCC) patients. However, its predictive role in the clinical outcomes of sorafenib treatment has been poorly documented. The correlation between LDH levels and clinical outcomes in HCC patients treated with sorafenib and included in the nationwide Italian database ITA.LI.CA was investigated here. PATIENTS AND METHODS: The ITA.LI.CA database contains data for 5,136 HCC patients. All patients treated with sorafenib treatment and with available LDH values were considered. Overall survival (OS) and time to progression (TTP) were compared in patients with LDH levels above and below a defined threshold, determined through an ROC analysis. An explorative analysis investigated the relationship between the variation of LDH levels during treatment and response to sorafenib. RESULTS: Baseline LDH levels were available for 97 patients. The most accurate cutoff value for LDH concentration was 297 U/L. Patients with LDH values above (n=45) and below (n=52) this threshold showed equal OS (12.0 months) and TTP (4.0 months) values. Data on LDH levels during sorafenib treatment were reported for 10 patients. LDH values decreased in 3 patients (mean difference = -219 U/L) who also reported a prolonged OS and TTP versus those with unmodified/increased LDH (OS: NE (not evaluated) vs. 8.0 months, p=0.0083; TTP: 19.0 vs. 3.0 months, p=0.008). CONCLUSIONS: The clinical benefits of sorafenib do not seem to be influenced by baseline LDH. According to the results of an explorative analysis, however, a decreased LDH concentration during sorafenib might be associated with improved clinical outcomes.

RESUMO

Sorafenib is an effective anti-angiogenic treatment for hepatocellular carcinoma (HCC). The assessment of tumor progression in patients treated with sorafenib is crucial to help identify potentially-resistant patients, avoiding unnecessary toxicities. Traditional methods to assess tumor progression are based on variations in tumor size and provide unreliable results in patients treated with sorafenib. New methods to assess tumor progression such as the modified Response Evaluation Criteria in Solid Tumors or European Association for the Study of Liver criteria are based on imaging to measure the vascularization and tumor volume (viable or necrotic). These however fail especially when the tumor response results in irregular development of necrotic tissue. Newer assessment techniques focus on the evaluation of tumor volume, density or perfusion. Perfusion computed tomography and Dynamic Contrast-Enhanced-UltraSound can measure the vascularization of HCC lesions and help predict tumor response to anti-angiogenic therapies. Mean Transit Time is a possible predictive biomarker to measure tumor response. Volumetric techniques are reliable, reproducible and time-efficient and can help measure minimal changes in viable tumor or necrotic tissue, allowing the prompt identification of non-responders. Volume ratio may be a reproducible biomarker for tumor response. Larger trials are needed to confirm the use of these techniques in the prediction of response to sorafenib.

RESUMO

In the last decade trans-arterial radioembolization has given promising results in the treatment of patients with intermediate or advanced stage hepatocellular carcinoma (HCC), both in terms of disease control and tolerability profile. This technique consists of the selective intra-arterial administration of microspheres loaded with a radioactive compound (usually Yttrium(90)), and exerts its therapeutic effect through the radiation carried by these microspheres. A careful and meticulous selection of patients is crucial before performing the radioembolization to correctly perform the procedure and reduce the incidence of complications. Radioembolization is a technically complex and expensive technique, which has only recently entered clinical practice and is supported by scant results from phase III clinical trials. Nevertheless, it may represent a valid alternative to transarterial chemoembolization (TACE) in the treatment of intermediate-stage HCC patients, as shown by a comparative retrospective assessment that reported a longer time to progression, but not of overall survival, and a more favorable safety profile for radioembolization. In addition, this treatment has reported a higher percentage of tumor shrinkage, if compared to TACE, for pre-transplant downsizing and it represents a promising therapeutic option in patients with large extent of disease and insufficient residual liver volume who are not immediately eligible for surgery. Radioembolization might also be a suitable companion to sorafenib in advanced HCC or it can be used as a potential alternative to this treatment in patients who are not responding or do not tolerate sorafenib.
