Abstract
BACKGROUND Cryopyrin-associated periodic syndrome (CAPS), a rare genetic autoimmune disease, is composed of familial cold autoinflammatory syndrome (FCAs), Muckle-Wells syndrome (MWS), and neonatal onset multisystem inflammatory disease (NOMID). MWS is caused by dominantly inherited or de novo gain-of-function mutations in the NOD-like receptor 3 (NLRP3) gene. At present, there is no report about the variation of R262W in China. CASE PRESENTATION We reported a 3-year-old Chinese boy who had recurrent fever without obvious inducement, bilateral conjunctival congestion, and urticarial-like rash. Laboratory examination showed elevation in leukocyte count, neutrophil count, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) and serum amyloid protein (SAA) levels. Whole exome sequencing identified a missense variation c.784-786delinsTGG (p.R262W) in the coding region of the NLRP3 gene. CONCLUSION A classical variant of the NLRP3 gene in a patient with MWS was first reported in China.

Abstract
Radiation-induced lung fibrosis (RILF) is a complication of radiotherapy in thoracic cancer patients. Thalidomide (THD) has a therapeutic effect on fibrotic and inflammatory disorders. The purpose of the current study was to investigate the therapeutic effect of THD on RILF in mice and better understand the underlying regulatory mechanisms of the therapeutic effect. We found that THD mitigated the fibrosis caused by irradiation in mice. The action of THD on RILF was related to the elevation of low levels reactive oxygen species (ROS), which inhibited the transforming growth factor‑β (TGF‑β)/Smad3 signaling pathway through activation of nuclear factor (erythroid-derived 2)-like 2 (Nrf2). Analysis of the therapeutic effect of THD using Nrf2-/- mouse model confirmed the role of Nrf2 in vivo. In addition, no radioprotective effect of THD on thoracic cancer cell lines was observed. In conclusion, these data showed that THD attenuated RILF in mice, which was mediated by Nrf2-dependent down-regulation of the TGF-β/Smad3 pathway, suggesting THD as a potential novel agent for RILF prevention.

Abstract
Chronic obstructive pulmonary disease (COPD) is characterized by a progressive airway obstruction that is not completely reversible and is mainly caused by smoking tobacco. COPD is a major cause of morbidity and mortality worldwide and there are currently no proven effective treatments. The pathogenesis of COPD involves several factors such as chronic inflammation, oxidative stress, and apoptosis. Cytokines play important roles in chronic inflammation. Thalidomide (Thal) has been used to treat multiple myeloma due to its inhibitory effects on IL-6-induced cell growth. We recently demonstrated that thalidomide (Thal) played important roles in cytokine-induced lung damage in a bleomycin-induced pulmonary fibrosis model in mice. We herein examined the preventative effects of Thal on cigarette smoke extract (CSE)-induced emphysematous changes in mice. We performed histological examinations and quantitative measurements of the expression of IL-1β and IL-6 mRNA, as well as apoptosis in CSE-induced mouse lung tissues treated with or without Thal. The results of the histological examination showed that Thal ameliorated CSE-induced emphysema in mice. It also inhibited the expression of IL-1β and IL-6 mRNA in mouse lung tissues. Thal decreased apoptosis in the mouse lung. In vitro studies revealed that Thal decreased 1) the expression of IL-1β and IL-6 in human lung epithelial cells, and 2) CSE-induced apoptosis and the inhibition of cell growth, which may be the underlying mechanisms for the preventative effects of Thal on emphysema. These results provide a rationale for exploring the clinical use of Thal for COPD.

Abstract
AIM: To assess the efficacy and tolerability of thalidomide in pediatric Crohn’s disease (CD).
METHODS: Six patients with refractory CD received thalidomide at an initial dose of 2 mg/kg per day for one month, then increased to 3 mg/kg per day or decreased to 1 mg/kg per day, and again further reduced to 0.5 mg/kg per day, according to the individual patient’s response to the drug.
RESULTS: Remission was achieved within three months. Dramatic clinical improvement was demonstrated after thalidomide treatment. Endoscopic and pathological improvements were also observed after thalidomide treatment, which was well tolerated by all patients.
CONCLUSION: Thalidomide is a useful drug for pediatric refractory CD.

Abstract
Angiogenesis inhibition, long studied in the treatment of malignancies, has begun to emerge as a potential therapeutic approach in managing inflammatory arthritis, particularly rheumatoid arthritis. The growth of new vessels is required for the development of the rheumatoid pannus, which then leads to extensive synovial inflammation and joint destruction. Vascular endothelial growth factor is the best studied mediator of angiogenesis, and several therapies have been developed that specifically target this molecule. Several other angiogenesis mediators, such as the angiopoietin-TIE system, hypoxia inducible factor and integrin alpha(V)beta(3), as well as naturally occurring inhibitors of angiogenesis, are also being investigated as potential therapeutic targets. Additionally, there are a number of drugs, including paclitaxel, 2-methoxyestradiol and fumagillin analogs, that might have a role in inhibiting angiogenesis and, thus, in treating proliferative synovitis.

Abstract
Pulmonary fibrosis in humans can occur as a result of a large number of conditions. In idiopathic pulmonary fibrosis (IPF), pulmonary function becomes progressively compromised resulting in a high mortality rate. Currently there are no proven effective treatments for IPF. We have recently reported that IL-6 and TGF-beta(1) plays an important role in proliferation and differentiation of lung fibroblasts, and all-trans-retinoic acid (ATRA) prevented bleomycin-induced lung fibrosis through the inhibition of these cytokines. Thalidomide (Thal) has been used in the treatment of multiple myeloma through the inhibitory effect on IL-6-dependent cell growth and angiogenesis. In this study, we examined the preventive effect of Thal on bleomycin-induced pulmonary fibrosis in mice. We performed histological examinations and quantitative measurements of IL-6, TGF-beta(1), collagen type Ialpha1 (COL1A1), vascular endothelial growth factor (VEGF), angiopoietin-1 (Ang-1) and angiopoietin-2 (Ang-2) in bleomycin-treated mouse lung tissues with or without the administration of Thal. Thal histologically ameliorated bleomycin-induced fibrosis in mouse lung tissues. Thal decreased the expressions of IL-6, TGF-beta(1), VEGF, Ang-1 Ang-2, and COL1A1 mRNA in mouse lung tissues. In addition, Thal inhibited angiogenesis in the lung. In vitro studies disclosed that Thal reduced 1) production of IL-6, TGF-beta(1), VEGF, Ang-1, and collagen synthesis from human lung fibroblasts, and 2) both IL-6-dependent proliferation and TGF-beta(1)-dependent transdifferentiation of the cells, which could be the mechanism underlying the preventive effect of Thal on pulmonary fibrosis. These data may provide a rationale to explore clinical use of Thal for the prevention of pulmonary fibrosis.

Abstract
Cough is an important defensive reflex of the airway and also a common symptom of respiratory disease. Cough after common respiratory virus infection is transient but is more persistent when associated with conditions such as asthma, rhinosinusitis, gastro-oesophageal reflux, chronic obstructive pulmonary disease and lung cancer. Persistent cough may be due to peripheral and/or central sensitisation of cough reflexes initiated by cough receptors, rapidly adapting receptors or nociceptors. Treatment directed at associated conditions such as asthma (with anti-inflammatories) and gastro-oesophageal reflux (with proton-pump inhibitors) improve cough. There remains a need to use drugs that suppress the neural activity of cough (termed nonspecific), as treatments directed at the clinical cause(s) of the underlying cough (termed specific) may not be effective. The most effective indirect antitussives are opioids such as morphine, codeine or pholcodeine, but they produce side effects such as drowsiness, nausea, constipation and physical dependence. Opioids such as kappa- and delta-receptor agonists, non-opioids such as nociceptin, neurokinin and bradykinin receptor antagonists, cannabinoids, vanilloid receptor-1 antagonists, blockers of Na+-dependent channels, and large conductance Ca2+-dependent K+-channel activators of afferent nerves may represent novel antitussives.

Abstract
Angiogenesis inhibition, which has been extensively studied for the treatment of various malignancies, is beginning to emerge as a new potential therapy for proliferative synovitis, particularly rheumatoid arthritis (RA). The rheumatoid pannus, the site of inflammation and joint destruction in the rheumatoid synovium, relies on the development of new vasculature to sustain its growth. A host of mediators have been shown to induce angiogenesis at the site of the inflamed synovium; these include vascular endothelial growth factor, fibroblast growth factor, integrin alpha(V)beta3, angiopoietin, prosta-glandin E1 and prostaglandin E2, and matrix metalloproteinases. In addition, hypoxia at the site of synovial inflammation contributes to angiogenesis stimulation. Several naturally-occurring inhibitors exist, such angiostatin and endostatin. There are a number of drugs undergoing study in the treatment of proliferative synovitis, which capitalise on the correlation between angiogenesis inhibition and the reduction of signs and symptoms of RA. Paclitaxel and an anti-integrin alpha(V)beta3 antibody, LM-609, are currently in clinical trials. Other drugs that may inhibit angiogenesis in RA include TNP-470 (formerly called AGM-1470), PPI-2458, PTK-787, bevacizumab and thalidomide. Many of these drugs have shown promise for the treatment of oncologic disorders, and are now being evaluated for the treatment of proliferative synovitis.

Abstract
Therapy for Crohn's disease (CD) is rapidly evolving with the emergence of new discoveries in disease pathogenesis. Since the approval of the first biological agent, infliximab, there have been several others that have been studied and are available for use within the context of clinical trials, in CD patients who do not respond to conventional medications or whose disease cannot be maintained in remission with the use of infliximab. The number of available drugs that have focused on the inhibition of TNF is growing. To avoid the injectable route of administering biologicals, several oral agents, such as thalidomide analogues, nonabsorbable antibiotics, such as rifaximin, and specific antibiotics, such as ornidazole, are being studied and considered for patients with CD. Hormonal therapies, such as growth hormone, coherin, medroxyprogesterone acetate and dehydroepiandrosterone, are other novel therapies for CD. Immunomodulators in use in other fields of medicine, including tacrolimus, 6-thioguanine and leflunomide, are being evaluated for the treatment of patients with CD and are also discussed. Several other promising therapies, such as cyclophosphamide, extracorporeal photochemotherapy, stem cell transplantation and the use of porcine whipworm, add to the available therapeutic armamentarium of this life-long remitting and relapsing disease. The future for CD patients is promising with the ever-expanding repertoire of drugs that are being studied.

Abstract
Forty years on from its worldwide withdrawal, thalidomide is currently undergoing a remarkable renaissance as a novel and powerful immunomodulatory agent. Over the last decade it has been found to be active in a wide variety of inflammatory and malignant disorders where conventional therapies have failed. Recently, considerable progress has been made in elucidating its complex mechanisms of action, which include both anticytokine and antiangiogenic properties. However, in addition to its well known teratogenic potential, it has a significant side effect profile that leads to cessation of treatment in up to 30% of subjects. In response to this, two new classes of potentially safer and non-teratogenic derivatives have recently been developed. This review summarises the biological effects, therapeutic applications, safety profile, and future potential of thalidomide and its derivatives.

Abstract
BACKGROUND Tumour Necrosis Factor alpha (TNFalpha) has been shown to contribute to heart failure (CHF) progression. AIMS We have tried to antagonise the detrimental effects of TNFalpha on skeletal muscle apoptosis, by using thalidomide, a drug that inhibits its biosynthesis. METHODS CHF was induced in 20 rats by injecting monocrotaline, which determines right ventricle (RV) failure. After 2 weeks, when CHF developed, 12 rats were treated with thalidomide 3.5.mg/kg per day for 2 weeks. Eight had saline and served as CHF controls. RESULTS Thalidomide failed to decrease TNFalpha and its second messenger sphingosine (SPH), but was able to prevent the shift toward the fast myosin heavy chains. In the Tibialis Anterior muscle of the thalidomide group, the degree of atrophy, the number of apoptotic nuclei and the levels of caspases, were similar to those of the CHF controls. CONCLUSIONS Thalidomide, at the doses used in this study, which are the same employed for the treatment of tubercolosis, leprosy, AIDS and cancer in humans, did not lower either TNFalpha or SPH and only marginally influenced the apoptosis-induced muscle atrophy. Since other TNFalpha blockers are under investigation for improving the clinical status of patients with CHF, the present data could be relevant in the design of randomised clinical trials in humans.

Abstract
The introduction of TNF- alpha -inhibiting biologicals has been a major therapeutic breakthrough in rheumatoid arthritis therapy. Against a background of conventional disease-modifying antirheumatic drug experience, this review focuses on present experiences and possible future developments. TNF inhibition results in profound improvement in the majority of rheumatoid arthritis patients, but non-response and adverse effects need attention. Adalimumab is being filed for approval. Other monoclonal antibodies or receptor constructs are in late development. Small molecule inhibitors of TNF production or signalling are a hot topic. One emerging target is nuclear factor kappa B and selective inhibition has proved effective in animal models of arthritis. Synovial proliferation in rheumatoid arthritis is characterised by diminished apoptosis of fibroblasts, whereas bone marrow precursor cells undergo accelerated apoptosis in active rheumatoid arthritis. Both abnormalities are seemingly ameliorated by TNF inhibition. Anti-apoptotic strategies will soon go into development for control of unresponsive rheumatoid arthritis.

Abstract
Thalidomide ([+]-alpha-phthalimidoglutarimide), a psychoactive drug that readily crosses the blood-brain barrier, has been shown to exhibit anti-inflammatory, antiangiogenic, and immunosuppressive properties through a mechanism that is not fully established. Due to the central role of NF-kappaB in these responses, we postulated that thalidomide mediates its effects through suppression of NF-kappaB activation. We investigated the effects of thalidomide on NF-kappaB activation induced by various inflammatory agents in Jurkat cells. The treatment of these cells with thalidomide suppressed TNF-induced NF-kappaB activation, with optimum effect occurring at 50 microg/ml thalidomide. These effects were not restricted to T cells, as other hematopoietic and epithelial cell types were also inhibited. Thalidomide suppressed H(2)O(2)-induced NF-kappaB activation but had no effect on NF-kappaB activation induced by PMA, LPS, okadaic acid, or ceramide, suggesting selectivity in suppression of NF-kappaB. The suppression of TNF-induced NF-kappaB activation by thalidomide correlated with partial inhibition of TNF-induced degradation of an inhibitory subunit of NF-kappaB (IkappaBalpha), abrogation of IkappaBalpha kinase activation, and inhibition of NF-kappaB-dependent reporter gene expression. Thalidomide abolished the NF-kappaB-dependent reporter gene expression activated by overexpression of TNFR1, TNFR-associated factor-2, and NF-kappaB-inducing kinase, but not that activated by the p65 subunit of NF-kappaB. Overall, our results clearly demonstrate that thalidomide suppresses NF-kappaB activation specifically induced by TNF and H(2)O(2) and that this may contribute to its role in suppression of proliferation, inflammation, angiogenesis, and the immune system.

Abstract
BACKGROUND Thalidomide improves clinical symptoms in patients with therapy refractory Crohn's disease, as shown in two recent studies. The mechanism of this effect however is still unknown. Suppression of tumour necrosis factor alpha (TNF-alpha) by thalidomide has been suggested as a possible mechanism. However, effects on other cytokines have not been adequately investigated. AIM The aim of our study was to investigate the effects of thalidomide on cytokine production in patients with inflammatory bowel disease (IBD). METHODS Ten patients with therapy refractory IBD (nine Crohn's disease, one ulcerative colitis) received thalidomide 300 mg daily in a 12 week open label study. Production of TNF-alpha, interleukin (IL)-1 beta, IL-6, and IL-12 was investigated in short term cultures of stimulated colonic lamina propria mononuclear cells (LPMC) and peripheral blood monocytes (PBMC) before and after 12 weeks of treatment. LPMC were also cultured with graded doses of thalidomide. RESULTS Three patients discontinued treatment because of sedative side effects. In the other patients, disease activity decreased significantly, with four patients achieving remission. Production of TNF-alpha and IL-12 decreased during treatment with thalidomide: LPMC (TNF-alpha: 42.3 (8.3) pg/ml v 16.4 (6.3); IL-12: 9.7 (3.3) v 5.0 (2.5); p<0.04) and PBMC (TNF-alpha: 62.8 (14.6) v 22.5 (9.2); p<0.02). Production of IL-1 beta and IL-6 did not change significantly. Culturing of LPMC with thalidomide showed a dose dependent decrease in TNF-alpha and IL-12 production. CONCLUSION The clinical effects of thalidomide in Crohn's disease may be mediated by reduction of both TNF-alpha and IL-12.

Several recent case reports and clinical trials have demonstrated that thalidomide is emerging as an efficacious alternative in the treatment of selected patients with refractory Crohn's disease. The effects of thalidomide are at least partly mediated by down-regulation of tumour necrosis factor (TNF)-alpha, a potent proinflammatory cytokine. However, thalidomide is also known to inhibit angiogenesis, and it has several other well-described immunomodulatory properties. Clinical studies have confirmed that previously refractory Crohn's disease patients respond to thalidomide, and many enter clinical remission. Efficacy usually occurs within 4 weeks. Thalidomide also has steroid-sparing properties, and it is particularly useful in treating oral and fistulous complications of Crohn's disease. Although it is usually tolerable, careful monitoring is recommended to prevent toxicities, such as birth defects and peripheral neuropathy. This review provides a detailed summary of the literature to date on the use of thalidomide treatment for Crohn's disease. Special attention is directed towards its history, mechanisms, and proposed role. The recent development of thalidomide analogues is also discussed briefly.

Abstract
Since its discovery, the understanding of the roles for TNF-alpha in human biology and disease has grown. Receptors for TNF are found on virtually all cell types, and many physiologic processes seem to be altered by TNF-alpha. The understanding of how TNF-alpha is involved in the pathophysiology of diseases, such as inflammatory diseases, has allowed the development of new drugs that can interfere with excess TNF-alpha and thus has allowed novel therapies for rheumatoid arthritis and Crohn's disease. As the role of TNF-alpha in other diseases becomes better understood, such TNF-alpha-modulating drugs may find further applications. In the skin, TNF-alpha is prominent cytokine that seems to be important in allergic and irritant contact dermatitis and inflammatory skin conditions. Modulating TNF-alpha activity in the skin may provide therapeutic benefits for a variety of skin conditions (Table 4). Tumor necrosis factor-alpha levels are elevated in skin lesions of psoriasis. A few reports have already suggested that etanercept and infliximab may offer a therapeutic effect in patients with psoriasis. Clinical studies evaluating the true efficacy of these drugs in psoriasis are under way. Specifically, the authors and others are involved in a double-blind, placebo-controlled study to assess the efficacy of etanercept for psoriasis. Thalidomide has been used off-label with some success to treat a number of dermatologic diseases, including several inflammatory skin conditions. Etanercept and infliximab might perhaps prove efficacious for inflammatory skin conditions as well. Finally, it is possible that drugs targeting TNF-alpha may have yet-unrecognized serious side effects. Because TNF-alpha seems to be a central cytokine in UVR-induced apoptosis, the chronic use of TNF-alpha-altering drugs might increase the risk for skin cancers. Tumor necrosis factor-alpha also plays some role in cutaneous wound healing; the effect these drugs might have on this process is also unknown at this time. Certainly, much is already [table: see text] known about TNF-alpha and how it plays many central roles. This understanding has allowed the development of useful new drugs for intractable disease. As the understanding of TNF-alpha and other cytokine biology increases, so will the number of potential therapeutic agents.

Abstract
The sedative and anti-nausea drug thalidomide, which causes birth defects in humans, has been shown to have both anti-inflammatory and anti-oncogenic properties. The anti-inflammatory effect of thalidomide is associated with suppression of cytokine expression and the anti-oncogenic effect with inhibition of angiogenesis. It is presently unclear whether the teratogenic properties of thalidomide are connected in any way to the beneficial, anti-disease characteristics of this drug. The transcription factor NF-kappaB has been shown to be a key regulator of inflammatory genes such as tumor necrosis factor-alpha and interleukin-8. Inhibition of NF-kappaB is associated with reduced inflammation in animal models, such as those for rheumatoid arthritis. We show here that thalidomide can block NF-kappaB activation through a mechanism that involves the inhibition of activity of the IkappaB kinase. Consistent with the observed inhibition of NF-kappaB, thalidomide blocked the cytokine-induced expression of NF-kappaB-regulated genes such as those encoding interleukin-8, TRAF1, and c-IAP2. These data indicate that the therapeutic potential for thalidomide may be based on its ability to block NF-kappaB activation through suppression of IkappaB kinase activity.

Abstract
Extraintestinal complications of inflammatory bowel disease (IBD) are often secondary to the underlying disease. Therefore, the first priority is to get active IBD into remission with medications, since surgery for IBD is not indicated for the treatment of extraintestinal complications. Symptoms of extraintestinal complications usually can be treated with simple agents; the treatment of patients with refractory symptoms and the use of more complex drug regimens should be done in cooperation with specialists on affected organ systems. Careful consideration of prescribed drugs is necessary because they may negatively influence the course of IBD.

Abstract
Behçet's disease is a systemic inflammatory disorder. The patients have repeated exacerbations and remissions of the symptoms. This disease may produce a wide variety of symptoms. In mild cases, mucocutaneous lesions are only the symptoms during the whole clinical course, whereas ocular lesions, which occur in about 70% of the patients, can cause blindness. Involvement of the gastrointestinal tract, CNS and large vessels is less frequent, but sometimes life-threatening. Colchicine, NSAIDs, corticosteroids and immunosuppressants are employed for the treatment of Behçet's disease with therapies tailored to individual patients depending on clinical manifestations. Cyclosporin A is the most effective drug for ocular lesions at the present, but its neurotoxicity, which occurs in 20-30% of patients receiving cyclosporin A, restricts usage of the agent. Many patients are still suffering from a severe form of uveitis and serious neurological symptoms, which are resistant to any conventional therapies. New drugs have been investigated for Behçet's disease. IFN-alpha therapy has shown significant efficacy for common symptoms including ocular lesions without any serious adverse effects. Thalidomide and its analogues also appear to be applicable to this disease. Monoclonal antibody to TNF-alpha is now in clinical trials. These novel therapeutic approaches may provide much needed treatment options for patients with Behçet's disease.

Abstract
A variety of clinical and experimental investigations have suggested that tumor necrosis factor alpha (TNF-alpha) may play a role in the pathophysiology of heart failure. Serum levels of TNF-alpha are elevated in patients with heart failure, and both cardiac and infiltrating cells of the myocardium can produce this proinflammatory cytokine. Both cardiac myocytes and nonmyocytes also express receptors for TNF-alpha, and experimental studies on isolated cells, muscles, and transgenic models demonstrate the ability of TNF-alpha to recapitulate functional and biochemical alterations resembling that observed in human congestive heart failure. The intracellular pathways affected by TNF-alpha include production of ceramide and an alteration in calcium metabolism. Recent studies in both animal models and clinical investigations suggest that anti-TNF-alpha therapies may limit the pathophysiologic consequences of congestive heart failure.
