-thalassaemia major is one of the most severe forms of chronic congenital anaemia. The recommended treatment consists in regular blood transfusions combined with chelating therapy to remove harmful iron accumulation in the body. The use of deferoxamine, the first chelating agent only available for subcutaneous administration is limited due to toxicity and the lack of compliance, despite its satisfactory therapeutic effects. An oral iron chelating agent, deferiprone, was authorised in Europe in August 1999 and recommended for the treatment of iron overload in patients with thalassaemia major when deferoxamine is contraindicated or inadequate. Despite a wide experience of the administration of deferiprone for thalassaemic patients, limited data are available on its use in children below 10 years and the need for additional data in this age subset was clearly indicated in the 2009 priority list approved by the Paediatric Committee at the European Medicines Agency (PDCO). In addition, according to the recent scientific advancements and in consideration of the anticipated benefit of this chelator in controlling cardiac iron overload, studies evaluating the effects of the deferiprone in all the paediatric ages and in all transfusion-dependent chronic congenital anaemia (including Sickle Cell Diseases) were also considered a critical therapeutic need. The DEEP project, in line with these premises, has been funded with the specific aim to produce a new oral liquid formulation of deferiprone suitable for the paediatric use and to provide evidences for the use of this chelator as first line therapy in the whole paediatric population (from 1 month to 18 years) affected by transfusion-dependent chronic anaemia. The condition under study in the DEEP project is rare. This poses special difficulties in the conduct of the studies due to the small patient population and the need to involve a large number of recruiting centres . However, being dedicated to develop an orphan drug, DEEP has been also recognised in the context of IRDiRC, the International Rare Diseases Research Consortium devoted to repurpose/develop 200 new drugs for Rare Diseases by the end of 2020. Main features of the DEEP project are: -The innovative design of the clinical studies including pharmacokinetic modelling for the definition of the most appropriate dosage of deferiprone in younger children, the cardiac MRI T2* evaluation as primary endpoint, a three years safety study aimed at evaluating deferiprone, in monotherapy or in combination, in the real worlds setting and, for the first time, a comparative efficacy-safety trial to compare the two existing oral chelators: deferiprone and deferasirox. -The DEEP Consortium including European and non-European Countries from the Mediterranean region where the transfusion-dependent congenital anaemia, in particular -thalassemia major, is particularly widespread: the collaboration within a multinational and multicultural network makes the Project extremely challenging due to many different ethical, methodological and social approaches to be explored and positively addressed.

Purpose of review Subclinical gut inflammation has been described in a significant proportion of patients with ankylosing spondylitis (AS), up to 10% of them developing it during the time of clinically overt inflammatory bowel disease. Histologic, immunologic, and intestinal microbiota alterations characterize the AS gut. Recent findings Microbial dysbiosis as well as alterations of innate immune responses have been demonstrated in the gut of AS. Furthermore, a growing body of evidence suggests that the gut of AS patients may be actively involved in the pathogenesis of AS through the production of proinflammatory cytokines, such as IL-23p19, and the differentiation of potentially pathogenic innate lymphoid cells producing IL-22 and IL-17. Finally, a strong correlation between the presence of subclinical gut inflammation and the degree of spine inflammation have been also proved in AS. Summary Subclinical gut inflammation and innate immune responses in AS may be considered a possible consequence of microbial dysbiosis. Relationships between cause and effect remain, however, to be answered. © Copyright 2015 Wolters Kluwer Health, Inc. All rights reserved.

Biological agents are widely used in rheumatology, dermatology and inflammatory bowel disease. Evidence about their efficacy and safety has been strengthened for all those therapeutic indications over the last decade. Biosimilar agents are monoclonal antibodies similar to previously approved biologics. In the European Union, they have been approved for all the indications in the management of immune-mediated inflammatory diseases (IMIDs), although data only in rheumatoid arthritis and ankylosing spondylitis are currently available. Direct evidence on efficacy, safety, and immunogenicity of biosimilars is mandatory in psoriasis, psoriatic arthritis, and inflammatory bowel disease, as well as in children. Based on the current evidence in the literature, we present the joint official position of the Italian Societies of Rheumatology, Dermatology and Inflammatory Bowel Disease on the use of biosimilars in IMIDs. © 2014 Elsevier B.V.

Background & Aims A staged prognostic model of cirrhosis based on varices, ascites, and bleeding has been proposed. We analyzed data on infections in patients with cirrhosis to determine whether it is also a prognostic factor. Methods Studies were identified by MEDLINE, EMBASE, COCHRANE, and ISI Web of Science searches (19782009); search terms included sepsis, infection, mortality, and cirrhosis. Studies (n = 178) reporting more than 10 patients and mortality data were evaluated (225 cohorts, 11,987 patients). Mortality after 1, 3, and 12 months was compared with severity, site, microbial cause of infection, etiology of cirrhosis, and publication year. Pooled odds ratio of death was compared for infected versus noninfected groups (18 cohorts, 2317 patients). Results Overall median mortality of infected patients was 38%: 30.3% at 1 month and 63% at 12 months. Pooled odds ratio for death of infected versus noninfected patients was 3.75 (95% confidence interval, 2.124.23). In 101 studies that reported spontaneous bacterial peritonitis (7062 patients), the median mortality was 43.7%: 31.5% at 1 month and 66.2% at 12 months. In 30 studies that reported bacteremia (1437 patients), the median mortality rate was 42.2%. Mortality before 2000 was 47.7% and after 2000 was 32.3% (P = .023); mortality was reduced only at 30 days after spontaneous bacterial peritonitis (49% vs 31.5%; P = .005). Conclusions In patients with cirrhosis, infections increase mortality 4-fold; 30% of patients die within 1 month after infection and another 30% die by 1 year. Prospective studies with prolonged follow-up evaluation and to evaluate preventative strategies are needed. © 2010 AGA Institute.

BACKGROUND AND AIMS: Several studies have reported that low doses of interferon can delay the development of hepatocellular carcinoma (HCC) and progression of chronic hepatitis C. We investigated the incidence of clinical events among participants of the Evaluation of PegIntron in Control of Hepatitis C Cirrhosis (EPIC)(3) program. METHODS: Data were analyzed from an open-label randomized study of patients with chronic hepatitis C who had failed to respond to interferon alfa plus ribavirin. All patients had compensated cirrhosis with no evidence of HCC. Patients received peginterferon alfa-2b (0.5 μg/kg/week; n = 311) or no treatment (controls, n = 315) for a maximum period of 5 years or until 98 patients had a clinical event (hepatic decompensation, HCC, death, or liver transplantation). The primary measure of efficacy was time until the first clinical event. RESULTS: There was no significant difference in time to first clinical event among patients who received peginterferon alfa-2b compared with controls (hazard ratio [HR], 1.452; 95% confidence interval [CI]: 0.880-2.396). There was no decrease in the development of HCC with therapy. The time to disease progression (clinical events or new or enlarged varices) was significantly longer for patients who received peginterferon alfa-2b compared with controls (HR, 1.564; 95% CI: 1.130-2.166). In a prospectively defined subanalysis of patients with baseline portal hypertension, peginterferon alfa-2b significantly increased the time to first clinical event compared with controls (P =.016). There were no new safety observations. CONCLUSIONS: Maintenance therapy with peginterferon alfa-2b is not warranted in all patients and does not prevent HCC. However, there is a potential clinical benefit of long-term suppressive therapy in patients with preexisting portal hypertension. © 2011 American Association for the Study of Liver Diseases.

The discovery of the therapeutic potential of stem cells offers new opportunities for the treatment of incurable neurological diseases. Based on their biological properties, stem cells act as manufacturers, maintaining the cellular tissue/organ homeostasis in physiological and pathological conditions. Thus, stem cell replacement therapy for central and peripheral nervous system disorders aims at repopulating the affected neural tissue with new neurons, as well as with other neural cells. In this review, we will report on investigations that are raising the promise and the understanding of the challenges behind translating stem cell biology into a novel clinical therapeutic potential for central and peripheral nervous system diseases.

Many placebo controlled trials and meta-analyses evaluated the efficacy of different drugs for the treatment of inflammatory bowel disease (IBD), including immunosuppressants and biologics. Their use is indicated in moderate to severe disease in non responders to corticosteroids and in steroid-dependent patients, as induction and maintainance treatment. Infliximab, as well as cyclosporine, is considered a second line therapy in the case of severe ulcerative colitis, or non-responders to intravenous corticosteroids. An adequate dosage and duration of therapy with thiopurines should be reached before evaluating their efficacy. Methotrexate is a valid option in patients with Crohn's disease but its use is confined to patients who are intolerant or non-responders to thiopurines. Evidence for the use of methotrexate in ulcerative colitis is insufficient. The use of thalidomide and mycophenolate mofetil is not recommended in patients with inflammatory bowel disease, these treatments could be considered in case of failure of all other therapeutic options. In patients with moderately active ulcerative colitis, refractory to thiopurines, the use of tacrolimus is considered an alternative to biologics. An increase of the dose or a decrease in the interval of administration of biological treatment could be useful in the presence of an incomplete clinical response. In the case of primary failure of an anti-tumor necrosis factor alpha a switch to another one should be considered. Data on the efficacy of combination therapy are up to now insufficient to consider this strategy in all IBD patients. The final outcome of the treatment should be considered the clinical remission, with mucosa healing, and not the clinical response. The evaluation of serum concentration of thiopurine methyl transferase activity, thiopurine metabolites, biologic serum levels and antibiologic antibodies could be useful for the management of the treatment but it has not been routinely applied in clinical practice. The evidence of high risk development of lymphoma and cutaneous malignancies should be considered in patients treated with immunosuppressants and biologics for a long period. © 2014 Baishideng Publishing Group Inc.

Background Recently, there have been increasingly frequent reports on the occurrence of macrophage activation syndrome (MAS) in patients with inflammatory bowel disease (IBD). Clinically, MAS is characterized mainly by fever, hepatosplenomegaly, cytopenia, and elevated circulating ferritin and CD25. Mortality, even if diagnosed rapidly, is high. Aim To identify all reports on MAS in IBD and to establish data on triggering agents, immunosuppression leading to MAS, and mortality. Methods A language unrestricted search on Pubmed and Scopus relating to the past 30 years was carried out by matching the following search-terms: h(a)emophagocytic lymphohistiocytosis OR h(a)emophagocytic lymphohistiocytic syndrome OR macrophage activation syndrome OR opportunistic infections OR cytomegalovirus OR Epstein-Barr virus AND Crohn's disease OR ulcerative colitis OR inflammatory bowel disease(s). Results Fifty cases were identified with an overall mortality of 30%. Virus-related MAS associated with cytomegalovirus or Epstein-Barr virus infections represents the main type of MAS, but in isolated cases bacterial infections precipitated the syndrome. In four cases (8%), a lymphoma was present at the time of MAS diagnosis or developed shortly thereafter. Thiopurine monotherapy was given before MAS onset in 56% of the patients, whereas multiple immunosuppression, including biologics, was administered to 24%. Conclusions In IBD patients, the syndrome appears to be triggered by infections, but genetic susceptibility may contribute to its development. Since immunosuppressive therapy represents the backbone of therapeutic interventions in IBD, with the risk of new, or the reactivation of latent infections, even more frequent cases of macrophage activation syndrome may be expected. © 2013 Blackwell Publishing Ltd.

Polycomb group (PcG) proteins are part of a conserved cell memory system that conveys epigenetic inheritance of silenced transcriptional states through cell division. Despite the considerable amount of information about PcG mechanisms controlling gene silencing, how PcG proteins maintain repressive chromatin during epigenome duplication is still unclear. Here we identified a specific time window, the early S phase, in which PcG proteins are recruited at BX-C PRE target sites in concomitance with H3K27me3 repressive mark deposition. Notably, these events precede and are uncoupled from PRE replication timing, which occurs in late S phase when most epigenetic signatures are reduced. These findings shed light on one of the key mechanisms for PcG-mediated epigenetic inheritance during S phase, suggesting a conserved model in which the PcG-dependent H3K27me3 mark is inherited by dilution and not by de novo methylation occurring at the time of replication. © 2011 Lanzuolo et al.
