Increased frequency of bronchial hyperresponsiveness in patients with inflammatory bowel disease.

Although bronchopulmonary manifestations are rare in inflammatory bowel disease (IBD), subclinical abnormalities have been described in up to 50% of cases. The pathophysiology of these abnormalities remains unknown. However, a latent inflammation of the bronchial mucosa secondary to the inflammation of the intestinal mucosa has been suggested. This subclinical inflammation may lead to increased bronchial responsiveness. We studied the bronchial responsiveness in 38 inflammatory bowel disease (IBD) patients, using the methacholine test. Bronchial hyperresponsiveness was defined by a PC20M < 16 mg/ml. Twenty-four healthy controls were also studied. There was no significant difference in baseline FEV1 between IBD patients and controls. However, there was a significantly greater fall in FEV1 in the IBD patients at the concentrations of methacholine tested. The frequency of bronchial hyperresponsiveness was significantly higher in the IBD population (45%) than in controls (17%; P < 0.03). Atopy, defined by skin test, was more common in IBD patients (42%) than in controls (21%). Even when only nonatopic subjects were considered, the frequency of bronchial hyperresponsiveness was significantly higher in IBD patients (41%) than in controls (5%; P < 0.02). Thus, subclinical bronchial hyperresponsiveness is common in IBD, and may be considered a further extraintestinal manifestation

Study of the Month. Palliative management of hepatocarcinoma with Sorafenib (Nexavar) : Results of the SHARP (Sorafenib Hepatocarcinoma Assessment Randomized Protocol) trial

peer reviewedCurative management of early-stage hepatocarcinoma may include partial hepatic resection, liver transplantation or tumoral necrosis using radiofrequency ablation or alcoholisation. Until recently, no efficient therapeutic mean was available for advanced hepatocarcinoma. Sorafenib is a multikinase inhibitor that decreases tumoral proliferation and angiogenesis, and increases apoptosis in many cancer models. The results of a phase 3 randomized, multicentric, study, entitled SHARP, have now demonstrated that Sorafenib increases survival in patients with advanced hepatocarcinoma developed in Child A cirrhosis. Mean survival gain was a little less than 3 months, without any radiologic response or improvement in the delay before symptomatic progression of the disease. The monthly cost of Sorafenib is a little more than 5,000 euros. It is now crucial to evaluate the potential role of Sorafenib in adjuvant therapy after liver resection or radiofrequency ablation of hepatocarcinoma. The CHU of Liège is taking part to a randomized, multicentric study evaluating the use of Sorafenib after liver resection or radiofrequency ablation for hepatocarcinoma. Another future evaluation could be the association of Sorafenib with other antitumoral agents

Impact of donor age over 70 years in donation after circulatory death liver transplantation: a 15 years of experience

peer reviewedBackground: Advanced donor age has been identified as a risk factor in donation after circulatory death (DCD 3) liver transplantation (LT), associated with poor graft function and development of ischemic cholangiopathy. In this study, we evaluated the results after DCD 3 LT using grafts from donors over 70 years compared to younger grafts (<70 years). Methods: We retrospectively analysed outcome after DCD 3 LT (n=228), comparing donors 70 years (n=53) and <70 years (n=175) from our center between 2003 and 2020. The two age groups were compared in terms of graft and patient survivals at 1, 3 and 5 years, in terms of donor and recipient demographics, transplant conditions and labora- tory values. Results: The overall graft survivals at 1, 3 and 5 years were 88, 75, 70 per cent respectively. Graft survival rates were not significantly diffe- rent at 5 years between the two groups (P = 0,536). No difference was noted in incidence of acute rejection, biliary strictures, hepatic artery thrombosis or retransplantation rates between the two groups. The time of cold ischemia was significatively lower in the older group (mean 235 min; SD 72) than in younger donor (mean 258 min; SD 72) (p=0.012). The posttransplant AST peak was significatively higher in the advanced age donor group than the second group with 2201±2703 U/L vs 1561U/L (SD 2151±2151 U/L), respectively (p= 0.04).Conclusions: Results for DCD LT from 70-yr-old grafts were similar to those from younger donors. Advanced donors should not be discarded for liver donation if other donor risk factors (such as cold ischemia time and graft quality) are limited

Challenges to reduce mortality due to hepatitis C: improving accessibility to therapy and compliance.

peer reviewedCurrent therapies with pegylated interferon and ribavirin are effective to eradicate the virus C. Improvements in the treatment are foreseen in the near future with combination of the current treatment with antiviral therapies (antiproteases, antipolymerases). Eradication of the virus, when obtained, has a favorable impact on an individual basis. However, to reduce the mortality related to the virus C at a population level, an important point is the accessibility to the therapy. It has been calculated that the impact of better management of hepatitis C to reduce mortality is minimal, due to a poor accessibility to the therapy. To obtain a significant additional reduction of mortality, a better screening, a better access to therapy and a better compliance are crucial

The FibroScan: a new non invasive method of liver fibrosis evaluation

peer reviewedThe FibroScan is a device allowing a non invasive diagnosis and quantification of liver fibrosis. The procedure is based on transient elastography and allows to record liver stiffness by measuring the velocity of shear wave across liver parenchyma. The elasticity is directly correlated to velocity of the wave. In chronic hepatitis C, there is a good correlation between liver elasticity and stage of fibrosis. The FibroScan has also been studied in other chronic liver diseases, such as hepatitis B, primary biliary cirrhosis, sclerosing cholangitis, auto-immune hepatitis, alcohol, steatosis, hemachromatosis with reproductible results. In a cirrhotic patient, it also allows to assess the severity of cirrhosis and to evaluate the risk of complication. It is a painless procedure, with a good acceptability by the patients. Therefore, the FibroScan can be regularly performed, allowing the follow up of fibrosis evolution over time

Management of hyperferritinemia

peer reviewedHemochromatosis is the most common genetic disorder in persons of northern European descent, and the majority of cases are caused by a mutation in the gene HFE. Genetic testing for hemochromatosis is therefore indicated in all patients with increases in transferrine saturation and ferritin levels. When this genetic testing does not demonstrate a hemochromatosis, other diseases responsible for elevated ferritin levels have to be ruled out, mainly hemolytic anemia, chronic inflammatory disorders, liver diseases such as hepatitis B or C, alcohol abuse, and non alcoholic fatty liver disease. In demonstrated iron overload with absence of classic causes, second-line genetic testing should be considered

Gastro-Esophageal Reflux and Asthma

peer reviewedGastro-oesophageal reflux (GER) is more frequent in asthmatic patients than in the community at large. A causative association between the two diseases is suspected. Twenty-four hour ambulatory intraoesophageal pH monitoring represents the golden standard for the diagnosis of GER. The medical and/or surgical treatment of reflux in asthmatic patients with GER can improve pulmonary symptoms and to a lesser extent pulmonary function. The selection of the patients who will benefit from a GER treatment is difficult. Some symptoms like intrinsic asthma, nocturnal crises, could predict a good response to GER treatment
