Since having been cloned in 1984, IL-1beta has been the subject of over 22,000 citations in Pubmed, among them over 800 reviews. This is because of its numerous effects. IL-1beta is a regulator of the body's inflammatory response and is produced after infection, injury, and antigenic challenge. It plays a role in various diseases, including autoimmune diseases such as rheumatoid arthritis, inflammatory bowel diseases and type 1 diabetes, as well as in diseases associated with metabolic syndrome such as atherosclerosis, chronic heart failure and type 2 diabetes. Macrophage are the primary source of IL-1, but epidermal, epithelial, lymphoid and vascular tissues also synthesize IL-1. IL-1beta production and secretion have also been reported from pancreatic islets. Insulin-producing beta-cells within pancreatic islets are specifically prone to IL-beta-induced destruction and loss of function. Macrophage-derived IL-1beta production in insulin-sensitive organs, leads to progression of inflammation and induction of insulin resistance in obesity. We summarize the mechanisms involved in inflammation and specifically the IL-1beta signals that lead to the progression of insulin resistance and diabetes. We highlight recent clinical studies and experiments in animals and isolated islets using IL-1beta as a potential target for the therapy of type 2 diabetes.

BH3-only BCL-2 family proteins are effectors of canonical mitochondrial apoptosis. They discharge their pro-apoptotic functions through BH1-3 pro-apoptotic proteins such as BAX and BAK, while their activity is suppressed by BH1-4 anti-apoptotic BCL-2 family members. The precise mechanism by which BH3-only proteins mediate apoptosis remains unresolved. The existing data are consistent with three mutually non-exclusive models (1) displacement of BH1-3 proteins from complexes with BH1-4 proteins; (2) direct interaction with and conformational activation of BH1-3 proteins; and (3) membrane insertion and membrane remodeling. The BH3-only proteins appear to play critical roles in restraining cancer and inflammatory diseases such as rheumatoid arthritis. Molecules that mimic the effect of BH3-only proteins are being used in treatments against these diseases. The cell death activity of a subclass of BH3-only members (BNIP3 and BNIP3L) is linked to cardiomyocyte loss during heart failure. In addition to their established role in apoptosis, several BH3-only members also regulate diverse cellular functions in cell-cycle regulation, DNA repair and metabolism. Several members are implicated in the induction of autophagy and autophagic cell death, possibly through unleashing of the BH3-only autophagic effector Beclin 1 from complexes with BCL-2/BCL-xL. The Chapters included in the current Oncogene Review issues provide in-depth discussions on various aspects of major BH3-only proteins.

A cohort of rheumatoid arthritis (RA) patients in the Lombardy Rheumatology Network (LOHREN) registry and receiving anti-TNF therapy was evaluated after 6, 12, 24, and 36 months. Of the 1114 patients in the registry 1064 met the clinical criteria for inclusion with 519 receiving infliximab, 303 adalimumab, and 242 etanercept. The therapeutic survival curve of these patients showed that the likelihood of continuing anti-TNF therapy was 78.8% after 12 months, 65.2% after 24 months, and 52.9% after 36 months, with a risk of dropout similar for inefficacy and adverse events. There were 405 anti-TNF therapy discontinuations (38.1%): 180 (16.9%) due to inefficacy, 194 (18.2%) adverse events, and 31 (2.9%) other reasons. Four deaths (2 septicemia, 1 postinfective cerebritis, 1 heart failure) were considered to be related to anti-TNF therapy. Of the discontinuations, 219 (54.1%) occurred within the first 12 months: 110 due to adverse events, 89 inefficacy, and 20 due to other reasons. After 36 months, the likelihood of survival on etanercept (62.5%) was significantly greater than the likelihood of survival on infliximab (49.1%) or adalimumab (53.6%). A higher risk of therapy discontinuations due to adverse events was associated with increasing age, a corticosteroid > 5 mg/day, a high erythrocyte sedimentation rate (ESR), a higher risk of therapy discontinuations due to inefficacy was associated with the previous use of > or = 4 disease-modifying antirheumatic drugs (DMARDs) and a high ESR. Comorbidities, increasing DAS28 values and co-therapy with methotrexate were associated with a lower risk of discontinuation.

The multicenter study conducted by Lorente and coworkers published in the previous issue of Critical Care demonstrates that matrix metalloproteinase (MMP)-9 and MMP-10 and their inhibitor tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) are promising novel biomarkers to predict severity and outcome of sepsis. In recent years MMPs have emerged as biomarkers in a variety of diseases, such as sepsis, coronary artery disease, cancer, heart failure, chronic lung disease and rheumatoid arthritis. MMPs constitute a family of proteinases that are expressed during developmental, physiological, and pathophysiological processes, for example as a response to infection. Excessive inflammation following infection may cause tissue damage, and MMPs are implicated in causing this immunopathology. The activity of MMPs is regulated by secretion of specific inhibitors (TIMPs). Studies using MMP inhibitors and MMP knockout mice indicate that MMPs play an essential role in infection and in the host response to infection. The measurement of MMP-9 and MMP-10 and their inhibitor TIMP-1 in the intensive care setting could be an attractive noninvasive tool for determination of outcome of septic patients.

Cardiovascular disease is the leading cause of premature mortality in patients with rheumatoid arthritis (RA). Pathophysiology of rheumatoid cardiovascular phenomenon is not fully understood, but systemic inflammation is thought to play a crucial role in the endothelial damage and accelerated course of atherosclerotic disease. Rheumatoid inflammation can also cause coronary pathology and heart failure. We present a case of transient cardiomyopathy in RA in the absence of occlusive coronary pathology, which mimics acute coronary syndrome.

Rheumatoid arthritis (RA) is a systemic disease of unknown etiology characterized by a chronic inflammatory process mainly leading to destruction of synovial membrane of small and major diarthrodial joints. The prevalence of RA within the general adult population is about 1% and female subjects in fertile age result mostly involved. It's an invalidating disease, associated with changes in life quality and a reduced life expectancy. Moreover, we can observe an increased mortality rate in this population early after the onset of the disease. The mortality excess can be partially due to infective, gastrointestinal, renal or pulmonary complications and malignancy (mainly lung cancer and non-Hodgkin lymphoma). Among extra-articular complications, cardiovascular (CV) involvement represents one of the leading causes of morbidity and mortality. Every cardiac structure can be affected by different pathogenic pathways: heart valves, conduction system, myocardium, endocardium, pericardium and coronary arteries. Consequently, different clinical manifestations can be detected, including: pericarditis, myocarditis, myocardial fibrosis, arrhythmias, alterations of conduction system, coronaropathies and ischemic cardiopathy, valvular disease, pulmonary hypertension and heart failure. Considering that early cardiac involvement negatively affects the prognosis, it is mandatory to identify high CV risk RA patients to better define long-term management of this population.

The adenosine receptors (A(1), A(2A), A(2B) and A(3)) are important and ubiquitous mediators of cellular signalling, which play vital roles in protecting tissues and organs from damage. Launched drugs include the adenosine receptor antagonists theophylline and doxofylline (both used as bronchodilators in respiratory disorders such as asthma), while several compounds are presently in clinical trials for a range of indications, including heart failure, Parkinson's disease, rheumatoid arthritis, cancer, pain and chronic obstructive pulmonary disease. A host of companies and institutions are addressing the huge potential for the development of selective adenosine receptor agonists and antagonists, so that it appears we are on the verge of a new wave of compounds approaching the market for many unmet medical needs. This review presents an analysis of the patenting activity in the area for 2006 and an interpretation and reflection on the developments that we can expect in the future.

Pure red cell aplasia (PRCA) is a disease with important relationships to autoimmune mechanisms. Although some autoimmune diseases, such as rheumatoid arthritis and systemic lupus erythematosus, have been associated with PRCA, until this point no studies have described the association between PRCA and primary antiphospholipid syndrome (APS). This is the first case report of PRCA associated with primary APS in a 39-year-old man with acute heart failure secondary to an anaemic condition that was diagnosed as pure red cell aplasia. The patient was later diagnosed with retinal artery and vein thromboses and bilateral deep venous thromboses of the femoral and popliteal veins. The most common causes of PRCA and other thrombophilias were ruled out in this investigation through complementary tests. This association with APS adds a new possibility to the study of PRCA pathophysiology.

IL-33 plays an important role in inflammatory diseases including hypersensitive diseases like asthma, autoimmune diseases like rheumatoid arthritis, cardiovascular diseases like heart failure and neurodegenerative diseases like Alzheimer's disease. Here we reported the generation of an IL-33 transgenic mouse, in which mouse IL-33 full-length cDNA was controlled under the CMV promoter. The transgenic IL-33 was released as a cleaved form with molecular weight of 18kDa in pulmonary, nephritic, cardiac and pancreatic tissues in transgenic mice and the pI of 18kDa peptide was about pH 3-5 on the 2D PAGE which was similar with the activated peptide of IL-33. Histological analysis showed massive airway inflammation with infiltration of eosinophils around bronchi and small blood vessels, hyperplasia of goblet cells and accumulation of mucus-like material in pulmonary tissue of transgenic mice. An increase of IL-5, IL-8, IL-13 and IgE was detected in bronchoalveolar lavage fluid (BALF) of transgenic mice, which are inflammatory factors. These findings suggest transgenic IL-33 could be cleaved and secreted in an activated form and play an important role in the pathogenesis of pulmonary inflammation.
