Modified spleen stiffness measurement by transient elastography is associated with presence of large oesophageal varices in patients with compensated…
2013
To evaluate the accuracy of liver transient elastography (TE), spleen TE and other noninvasive tests (AAR, APRI score, platelet count, platelet/spleen ratio) in predicting the presence and the size of oesophageal varices in compensated hepatitis C virus (HCV) cirrhosis, we studied 112 consecutive patients with compensated HCV cirrhosis who underwent biochemical tests, gastrointestinal endoscopy, liver TE and spleen TE by Fibroscan(®) (Echosens, Paris, France) using a modified software version with a range between 1.5 and 150 kPa. Spleen TE was not reliable in 16 patients (14.3%). Among the 96 patients with a valid measurement (69.8% men, mean age: 63.2 ± 9.5 years), 43.7% had no oesophageal…
Mortality risk according to different clinical characteristics of first episode of liver decompensation in cirrhotic patients: a nationwide, prospect…
2013
Abstract OBJECTIVES: The occurrence of decompensation marks a crucial turning point in the course of cirrhosis. The purpose of this study was to assess the risk of mortality according to the clinical characteristics of first decompensation, considering also the impact of acute-on-chronic liver failure (AoCLF). METHODS: We conducted a prospective nationwide inception cohort study in Italy. Decompensation was defined by the presence of ascites, either overt or detected by ultrasonography (UD), gastroesophageal variceal bleeding (GEVB), and hepatic encephalopathy (HE). AoCLF was defined according to the Asian Pacific Association for the Study of the Liver criteria. Multivariable Cox proportion…
Predicting Mortality Risk in Patients With Compensated HCV-Induced Cirrhosis: A Long-Term Prospective Study
2009
OBJECTIVES: The identification of prognostic factors associated with mortality is crucial in any clinical setting. METHODS: We enrolled in a prospective study 352 patients with compensated hepatitis C virus (HCV)-induced cirrhosis, consecutively observed between 1989 and 1992. At entry, patients underwent upper endoscopy to detect esophageal varices, and were then surveilled by serial clinical and ultrasonographic examination. The model for end-stage liver disease (MELD) score was calculated with information collected at enrollment. Baseline predictors and intercurrent events associated with mortality were assessed using the Cox regression model. RESULTS: During a median follow-up of 14.4 y…
Disparities in the prevalence of clinical features between systemic juvenile idiopathic arthritis and adult-onset Still's disease
2022
Abstract Objective To compare clinical features and treatments of patients with systemic JIA (sIJA) and adult-onset Still’s disease (AOSD). Methods The clinical charts of consecutive patients with sJIA by International League of Association of Rheumatology criteria or AOSD by Yamaguchi criteria were reviewed. Patients were seen at a large paediatric rheumatology referral centre or at 10 adult rheumatology academic centres. Data collected included clinical manifestations, inflammation biomarkers, systemic score, macrophage activation syndrome (MAS), parenchymal lung disease, disease course, disability, death and medications administered. Results A total of 166 patients (median age at diagnos…
Lung Compartmentalization of Increased TNF Releasing Ability by Mononuclear Phagocytes in Pulmonary Sarcoidosis
1989
The TNF is a monokine with cytotoxic and tumor-necrosing activities; in addition, TNF may play a role in inflammatory processes. The present study evaluates spontaneous and LPS-mediated release of TNF by AMs and autologous peripheral BMs of normal subjects and patients with pulmonary sarcoidosis. A recently developed cytotoxicity assay, specific for detection of TNF activity, was applied. This study demonstrates that (1) unstimulated mononuclear phagocytes released low levels of TNF with no differences between groups; (2) when effector cells were stimulated with LPS, AMs from patients with active pulmonary sarcoidosis released more TNF than AMs recovered from normal subjects and from patien…
Spontaneous Monokine Release by Alveolar Macrophages in Chronic Sarcoidosis
1991
In pulmonary sarcoidosis an activation of alveolar T lymphocytes and alveolar macrophages (AM) has been demonstrated. There is evidence that in contrast to acute disease a heightened T-cell response cannot be observed in the chronic phase of sarcoidosis. The role of AM in the inflammatory process of chronic sarcoidosis is not yet intensively evaluated. To address this question we measured the release of tumor necrosis factor alpha (TNFα) and interleukin-1 (IL-1) by AM of 39 patients with chronic sarcoidosis (duration > 4 years; 30 active, 9 inactive diseases) without therapy and correlated the monokine release with parameters of T-cell alveolitis and the course of the disease. The T4/T8 …
A prospective evaluation of the activity of human granulocyte-colony stimulating factor on the prevention of chemotherapy-related neutropenia in pati…
1993
After informed consent, 86 patients with advanced cancer undergoing potentially myelosuppressive cytotoxic chemotherapy were randomized to receive placebo or subcutaneous granulocyte - colony stimulating factor (G- CSF) 5 μg/Kg/day in order to prevent severe neutropenia and its related morbidity. The incidence of neutropenia (absolute neutrophil count <1, 000/mm3) was significantly reduced in patients receiving G-CSF than in controls (18% versus 42%; P <0.05). The duration of neutropenia was also shortened by the administration of G-CSF (4.8 versus 8.2 days; P <0.05). Therapy with G-CSF has also a positive impact on the dose-intensity of employed regimens. Patients treated with G-CSF showed…
Reduced Sympathetic Innervation in Endometriosis is Associated to Semaphorin 3C and 3F Expression
2016
Endometriosis is a chronic inflammatory disease and one of the most common causes of pelvic pain. The mechanisms underlying pain emergence or chronic inflammation during endometriosis remain unknown. Several chronic inflammatory diseases including endometriosis show reduced amounts of noradrenergic nerve fibers. The source of the affected innervation is still unclear. Semaphorins represent potential elicitors, due to their known role as axonal guidance cues, and are suggested as nerve repellent factors in different chronic inflammatory diseases. Therefore, semaphorins might influence the progress of neuroinflammatory mechanisms during endometriosis. Here, we analyzed the noradrenergic inner…
Isolation in small populations of Wayampi Amerindians promotes endemicity and homogenisation of their faecal virome, but its distribution is not enti…
2018
The isolated community of the Wayampi Amerindians has been extensively studied for the presence of beta lactamase-producing enterobacteria and their gut microbiota. However, no information about their virome was available. This study tries to establish potential associations between the virome and diverse epidemiological data, through the metagenomic study of the faecal prophages and DNA viruses from 31 samples collected in 2010. Taxonomic assignments, composition, abundance and diversity analyses were obtained to characterise the virome and were compared between groups according to several demographic, environmental and medical data. Prophages outnumbered viruses. Composition and abundance…
