Chronic TNF exposure induces glucocorticoid-like immunosuppression in the alveolar macrophages of aged mice that enhances their susceptibility to pneumonia. Aging Cell 2024; 23:e14133. [PMID: 38459711 PMCID: PMC11296116 DOI: 10.1111/acel.14133] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 01/22/2024] [Accepted: 02/12/2024] [Indexed: 03/10/2024] Open
Abstract
Chronic low-grade inflammation, particularly elevated tumor necrosis factor (TNF) levels, occurs due to advanced age and is associated with greater susceptibility to infection. One reason for this is age-dependent macrophage dysfunction (ADMD). Herein, we use the adoptive transfer of alveolar macrophages (AM) from aged mice into the airway of young mice to show that inherent age-related defects in AM were sufficient to increase the susceptibility to Streptococcus pneumoniae, a Gram-positive bacterium and the leading cause of community-acquired pneumonia. MAPK phosphorylation arrays using AM lysates from young and aged wild-type (WT) and TNF knockout (KO) mice revealed multilevel TNF-mediated suppression of kinase activity in aged mice. RNAseq analyses of AM validated the suppression of MAPK signaling as a consequence of TNF during aging. Two regulatory phosphatases that suppress MAPK signaling, Dusp1 and Ptprs, were confirmed to be upregulated with age and as a result of TNF exposure both ex vivo and in vitro. Dusp1 is known to be responsible for glucocorticoid-mediated immune suppression, and dexamethasone treatment increased Dusp1 and Ptprs expression in cells and recapitulated the ADMD phenotype. In young mice, treatment with dexamethasone increased the levels of Dusp1 and Ptprs and their susceptibility to infection. TNF-neutralizing antibody reduced Dusp1 and Ptprs levels in AM from aged mice and reduced pneumonia severity following bacterial challenge. We conclude that chronic exposure to TNF increases the expression of the glucocorticoid-associated MAPK signaling suppressors, Dusp1 and Ptprs, which inhibits AM activation and increases susceptibility to bacterial pneumonia in older adults.

Abstract
Orbital inflammatory pseudotumor (OIP) is a benign, non-specific inflammatory disorder that commonly occurs in middle-aged adults and is usually unilateral but can occur bilaterally. Its clinical manifestations have tremendous clinical heterogeneity and vary according to the site of infiltration and the degree of lesions, including orbital pain, swelling, diplopia, proptosis, restricted eye movement, and decreased visual acuity. Clinical features, Image characteristics and pathological examinations often need to be evaluated to confirm the diagnosis. Currently, there is no systematic research on the pathogenesis of OIP, which may be related to immunity or infection. The first-line treatment is glucocorticoids. Radiotherapy, immunosuppressants, and biologics can be considered for treatment-resistant, hormone-dependent, or intolerant patients. In this review, we aim to summarize and focus on new insights into OIP, including new diagnostic criteria, pathogenesis, and discoveries in new drugs and treatment strategies. In particular, we highlight the literature and find that T cell-mediated immune responses are closely related to the pathogenesis of OIP. Further exploration of the mechanism and signaling pathway of T cells in the immune process will help to identify their therapeutic targets and carry out targeted therapy to treat refractory OIP and reduce the side effects of traditional treatments.

Abstract
Rheumatoid arthritis (RA) is an autoimmune disease involving synovial joints, and it is known that extra-articular manifestations that may affect the central and peripheral nervous systems may develop during its course. Rheumatoid meningitis is very rare among all neurological involvements. In this study, cases diagnosed as rheumatoid meningitis with clinical, imaging, laboratory, and histopathological features are presented, and the aim of the study is to present current approaches in the diagnosis and treatment of rheumatoid meningitis in the light of case studies and current literature. The data of the patients who were followed up with the diagnosis of rheumatoid meningitis in neurology clinic between 2017 and 2021 were reviewed retrospectively. Three cases diagnosed with rheumatoid meningitis are presented in detail. In the first case, the diagnosis was reached by clinical, imaging, and laboratory findings as well as treatment response, while the diagnosis was made by histopathological verification in the second case. The third case shows that spontaneous remission can be observed in the course of rheumatoid meningitis. Rheumatoid meningitis, which is one of the rarest involvements in the course of RA, may present with headaches, focal neurological deficits, seizures, and altered consciousness. A meningeal biopsy is recommended when the differential diagnosis cannot be ruled out with imaging and laboratory findings. In the differential diagnosis Mucobacterium tuberculosis, syphilis, neuro-sarcoidosis, immunoglobulin G4-related disease, lymphoproliferative diseases, and systemic metastasis should be kept in mind. Aggressive RA management is recommended for treatment.

Abstract
Key Points This renal biopsy study documents clinical renal dysfunction and pathologic lesions encountered in patients after anti-TNFα therapy and compares them with similar patients without treatment. This study highlights the spectrum of autoimmune, serologic, and other kidney adverse effects of anti-TNFα therapy. Unrelated active or chronic renal lesions including amyloidosis secondary to the underlying systemic inflammatory states may be observed. Background Anti-TNFα inhibitors, as biological agents, are used in autoimmune inflammatory states, rheumatoid arthritis (RA), psoriatic arthritis (PA), and Crohn disease. They can induce autoimmune serologic responses and clinical disorders, including systemic vasculitis and lupus-like diseases, affecting the kidney. Methods Retrospective analysis of clinicopathologic features of kidney disease after anti-TNFα therapy (treatment group) from our renal biopsy files from 2000 to 2018 is conducted and compared with 106 patients without therapy (control group). Results Forty-eight patients using anti-TNFα agents had renal biopsies: RA in 30, PA six, Crohn disease six, RA and PA one, RA and Crohn disease one, and others four. Twenty received etanercept, 15 adalimumab, eight infliximab, and five two forms of agents manifesting new-onset nephritic syndrome or CKD, 17 with AKI and 16 nephrotic syndrome, with recent ANCA and/or lupus serology. The renal lesions were crescentic GN in eight, pauci-immune–type in five, and ANCA+ in five. Lupus or lupus-like nephritis was seen in six: International Society of Nephrology/Renal Pathology Society 2018 class II—2, class V—2, class III+V—1, and class IV+V—1, and concurrent fibrillary GN, scleroderma/thrombotic microangiopathy (TMA), and amyloidosis in three. Renal lesions unrelated to anti-TNFα therapy or underlying autoimmune disease were noted in 23 patients (e.g. , diabetic nephropathy, interstitial nephritis, acute tubular injury, infection-related GN); immunoglobulin A nephropathy, renal sarcoidosis, and amyloid A amyloidosis were noted in five patients. TMA was recognized in five patients, one associated with scleroderma and one anti-phospholipid antibodies, and two had nephrotic syndrome secondary to podocytopathy. The control group was similar with higher number of immune-mediated GN, interstitial nephritis, and amyloidosis. Conclusion: The renal lesions during anti-TNFα therapy have an autoimmune basis such as ANCA and lupus or lupus-like disease, correlated with new-onset serology, while others were similar to those observed in the control group. Renal biopsy findings integrated with clinical features and therapy can identify the underlying pathophysiologic process for appropriate management.

Abstract
Intrathecal pseudodelivery of drugs is a novel route to administer medications to treat neurodegenerative diseases based on the CSF-sink therapeutic strategy by means of implantable devices. While the development of this therapy is still in the preclinical stage, it offers promising advantages over traditional routes of drug delivery. In this paper, we describe the rationale of this system and provide a technical report on the mechanism of action, that relies on the use of nanoporous membranes enabling selective molecular permeability. On one side, the membranes do not permit the crossing of certain drugs; whereas, on the other side, they permit the crossing of target molecules present in the CSF. Target molecules, by binding drugs inside the system, are retained or cleaved and subsequently eliminated from the central nervous system. Finally, we provide a list of potential indications, the respective molecular targets, and the proposed therapeutic agents.

Abstract
O-GlcNAcylation is a reversible post-translational modification that regulates numerous cellular processes, including embryonic development as well as immune responses. However, its role in inflammation remains ambiguous. This study was designed to examine the role of O-GlcNAcylation in rheumatoid arthritis (RA) and its regulation using human RA patient-derived synovial fibroblasts (RASFs). The efficacy of penta-O-galloyl-beta-D-glucose (PGG), a potent anti-inflammatory molecule, in regulating inflammatory processes in human RASFs was also evaluated. Human synovial tissues and RASFs exhibited higher expression of O-GlcNAcylation compared to their non-diseased counterparts. Pretreatment of RASFs with Thiamet G, an inhibitor of O-GlcNAcase, markedly increased the O-GlcNAc-modified proteins and concomitantly inhibited the IL-1β-induced IL-6 and IL-8 production in human RASFs in vitro. Pretreatment of human RASFs with PGG (0.5-10 µM) abrogated IL-1β-induced IL-6 and IL-8 production in a dose-dependent manner. Immunoprecipitation analysis showed that PGG inhibited O-GlcNAcylation of TAB1 to reduce its association with TGF β-activated kinase 1 (TAK1) and its autophosphorylation, an essential signaling step in IL-1β-induced signaling pathways. Molecular docking in silico studies shows that PGG occupies the C174 position, an ATP-binding site in the kinase domain to inhibit TAK1 kinase activity. Oral administration of PGG (25 mg/kg/day) for 10 days from disease onset significantly ameliorated rat adjuvant-induced (AIA) in rats. PGG treatment reduced the phosphorylation of TAK1 in the treated joints compared to AIA joints, which correlated with the reduced disease severity and suppressed levels of serum IL-1β, GM-CSF, TNF-α, and RANKL. These findings suggest O-GlcNAcylation as a potential therapeutic target and provide the rationale for testing PGG or structurally similar molecule for their therapeutic efficacy.

Abstract
Immunoglobulin A (IgA) nephropathy (IgAN) is the most common glomerulonephritis worldwide, characterized by IgA deposits in the glomerular mesangium. It has a progressive nature and can eventually lead to end-stage kidney failure. It can occur as a potential side effect of treatment with tumor necrosis factor alpha antagonist that has been used for numerous chronic inflammatory conditions, such as Crohn's disease. In this study, the case of a 33-year-old man with renal dysfunction, nephrotic proteinuria, and erythrocyturia is described. He had had a history of Crohn's disease for 8 years and had been treated with adalimumab for the past 7 years. The diagnosis of IgAN was confirmed by kidney biopsy. After discontinuance of adalimumab and the induction of corticosteroid therapy, he made a remarkable recovery. Four years after the first presentation of IgAN and discontinuation of adalimumab, his renal function was normal with no proteinuria and only mild erythrocyturia.

Abstract
BACKGROUND AND PURPOSE Rheumatoid meningitis (RM) is a neurological complication of rheumatoid arthritis (RA). Current evidence is based on case reports and partial reviews. METHODS This is a systematic review and meta-analysis following the PRISMA statement. The aim is to describe the characteristics of the disease, including clinical, imaging and laboratory findings, treatment, outcomes and prognosis reported in the literature. RESULTS In all, 103 studies with 130 cases were included. RM affected adults with an average age of 62 years, with or without a previous RA diagnosis. RA activity and time with the disease were associated with a worse prognosis. Most common clinical manifestations were transient focal neurological signs (64.6%), systemic symptoms (51.3%), episodic headache (50.4%) and neuropsychiatric alterations (47.7%). Joint manifestations were present in only 27.4% of cases. Brain magnetic resonance imaging showed unilateral or bilateral involvement, predominantly frontoparietal. Both pachymeninges and leptomeninges were affected, the latter more frequently (82.88%). The laboratory findings included increased levels of rheumatoid factor (89.71%), anti-cyclic citrullinated peptide (89.47%), C-reactive protein (82.54%) and erythrocyte sedimentation rate (81.81%). Cerebrospinal fluid analysis showed an increase in the protein level (76.14%), with pleocytosis (85.19%) of mononuclear predominance (89.19%). Biopsy was performed in 72.52% of the patients. Corticosteroid pulse therapy was the main induction therapy. Disease relapse occurred in 31.17% of patients, whilst 54.54% had a full recovery. CONCLUSIONS Rheumatoid meningitis must be considered in adult patients with or without RA diagnosis, high-dose corticosteroid induction therapy should be installed and maintenance therapy plays a key role. It is not recommended to use anti-TNF as an induction therapy. Nowadays, RM has a significantly better outcome. These findings may aid clinicians in timely RM diagnosis and treatment, thus improving its outcomes.

Abstract
Since we have gained an understanding of the immunological pathophysiology of rheumatic diseases such as rheumatoid arthritis and systemic lupus erythematosus, treatment based on biological drugs has become a fundamental axis. These therapies are oriented towards the regulation of cytokines such as tumour necrosis factor-alpha (TNF-α), interleukin (IL)-6, IL-1, and the modulation of cell-mediated immunity (B cells and T cells) by anti CD20 or anti CTAL-4 agents, and can increase the risk of associated infections or adverse events (AE). In this context, the entry of biotherapeutics represented a challenge for pharmacovigilance, risk management and approval by the main global regulatory agencies regarding biosimilars, where efficacy and safety are based on comparability exercises without being an exact copy in terms of molecular structure. The objective of this review is divided into three fundamental aspects: (i) to illustrate the evolution and focus of pharmacovigilance at the biopharmaceutical level, (ii) to describe the different approved recommendations of biopharmaceuticals (biological and biosimilars) and their use in rheumatic diseases (RDs) such as rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), systemic lupus erythematosus (SLE) and other less frequent RD like cryopyrin-associated autoinflammatory syndromes (CAPS), and (iii) to identify the main AE reported in the post-marketing phase of RD biopharmaceuticals.

Patients with autoimmune and/or inflammatory diseases (AIIDs) are prone to serious infectious complications such as Pneumocystis jirovecii pneumonia (PJP). In non-HIV patients, the prognosis is poorer, and diagnostic tests are of lower sensitivity. Given the low incidence of PJP in AIIDs, with the exception of granulomatosis with polyangiitis, and the non-negligible side effects of chemoprophylaxis, routine prescription of primary prophylaxis is still debated. Absolute peripheral lymphopenia, high doses of corticosteroids, combination with other immunosuppressive agents, and concomitant lung disease are strong predictors for the development of PJP and thus should warrant primary prophylaxis. Trimethoprim-sulfamethoxazole is considered first-line therapy and is the most extensively used drug for PJP prophylaxis. Nevertheless, it may expose patients to side effects. Effective alternative drugs such as atovaquone or aerosolized pentamidine could be used when trimethoprim-sulfamethoxazole is not tolerated or contraindicated. No standard guidelines are available to guide PJP prophylaxis in patients with AIIDs. This review covers the epidemiology, risk factors, and prevention of pneumocystis in the context of AIIDs.

The Association of TNF-Alpha Inhibitors and Development of IgA Nephropathy in Patients with Rheumatoid Arthritis and Diabetes. Case Rep Nephrol 2020; 2020:9480860.

Abstract
IgA nephropathy (IgAN) is a rather uncommon complication of TNF-alpha inhibition with a range of findings such as asymptomatic microscopic/macroscopic hematuria or different degrees of proteinuria and could progress to end-stage renal disease. We are reporting three patients with longstanding rheumatoid arthritis (RA), which developed IgAN while receiving TNF-alpha inhibitors. All off our three patients had RA, which lasted 2-4 years, and none of them had a prior history of chronic kidney disease. Two patients were treated with adalimumab while one patient was treated with golimumab. Discontinuation of anti-TNF-alpha therapy and initiation of immunosuppressive therapy led to improvement in serologic abnormalities and renal function in two patients, while the third patient's 24-hour proteinuria was only partially reduced, which supports previous reports on TNF-alpha inhibitor induced autoimmunity. Two of our patients had previously been diagnosed with type 2 diabetes mellitus while the third patient developed diabetes years after the onset of IgAN. This is in line with the previously described association of IgAN and diabetes mellitus. To our best knowledge, this is the first report to analyze the development of IgAN as a potential consequence of anti-TNF-alpha therapy and its possible association with pretreatment or posttreatment diabetes.

Abstract
BACKGROUND In Phase 3 studies of ustekinumab, a fully human monoclonal IL-12/23p40 antibody approved for moderate-to-severe Crohn's disease, patients entered a long-term extension after completing 8 weeks of induction and 44 weeks of maintenance treatment. Efficacy through 92 weeks and safety through 96 weeks of IM-UNITI maintenance are reported. METHODS UNITI-1 (TNF-antagonist failures) and UNITI-2 (conventional therapy failures) patients (N = 1281) entered IM-UNITI, including 397 ustekinumab intravenous induction responders randomised to subcutaneous ustekinumab 90 mg every 12 weeks, every 8 weeks, or placebo and 884 nonrandomised patients. Dose-adjustment to 90 mg every 8 weeks occurred in patients randomised to 90 mg every 12 weeks and placebo patients with loss of response (Weeks 8-32). All Week 44 completers could enter the long-term extension without further dose adjustment. Placebo patients discontinued following study unblinding. RESULTS A total of 718 patients (all treated) entered the long-term extension (298 randomised and 420 not randomised). Overall, 86.5% (621/718) completed Week 96. The proportions of randomised patients in clinical remission were generally maintained from Week 44 through 92 in ustekinumab 90 mg every 12 weeks (77.4% to 72.6%), every 8 weeks (84.1% to 74.4%), and prior dose adjustment groups (63.4% to 53.5%). At Week 92, the proportions of patients in clinical remission were similar in the ustekinumab 90 mg every 12 weeks and every 8 weeks groups and lower in patients with prior dose adjustment. Proportions of patients in clinical remission at Week 92 for all treated every 8 weeks (64.4%) and every 12 weeks (64.3%) groups were lower than randomised every 8 weeks (74.4%) and every 12 weeks (72.6%) groups, but similarly maintained. Safety events (per hundred patient-years) were similar among all placebo and ustekinumab patients (Week 0-96), including adverse events (484.39 vs 447.76), serious adverse events (19.24 vs 18.82), and serious infections (4.09 vs 4.02). No dose effect was observed. CONCLUSIONS Subcutaneous ustekinumab maintained clinical response and remission through Week 92. No new safety signals were observed. ClinicalTrials.gov number NCT01369355.

Optimal regimens of sulfamethoxazole-trimethoprim for chemoprophylaxis of Pneumocystis pneumonia in patients with systemic rheumatic diseases: results from a non-blinded, randomized controlled trial. Arthritis Res Ther 2017; 19:7. [PMID: 28100282 PMCID: PMC5241919 DOI: 10.1186/s13075-016-1206-8] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2016] [Accepted: 12/08/2016] [Indexed: 11/13/2022] Open
Abstract
Background Sulfamethoxazole-trimethoprim (SMX/TMP) is a standard drug for the prophylaxis of Pneumocystis pneumonia (PJP) in immunosuppressed patients with systemic rheumatic diseases, but is sometimes discontinued due to adverse events (AEs). The objective of this non-blinded, randomized, 52-week non-inferiority trial was to quest an effective chemoprophylaxis regimen for PJP with a low drug discontinuation rate. Results at week 24 were reported. Methods Adult patients with systemic rheumatic diseases who started prednisolone ≥0.6 mg/kg/day were randomized into three dosage groups: a single-strength group (SS, SMX/TMP of 400/80 mg daily), half-strength group (HS, 200/40 mg daily), and escalation group (ES, started with 40/8 mg daily, increasing incrementally to 200/40 mg daily). The primary endpoint was non-incidence rates (non-IR) of PJP at week 24. Results Of 183 patients randomly allocated at a 1:1:1 ratio into the three groups, 58 patients in SS, 59 in HS, and 55 in ES started SMX/TMP. A total of 172 patients were included in the analysis. No cases of PJP were reported up to week 24. Estimated non-IR of PJP in patients who received daily SMX/TMP of 200/40 mg, either starting at this dose or increasing incrementally, was 96.8–100% using the exact confidence interval as a post-hoc analysis. The overall discontinuation rate was significantly lower with HS compared to SS (p = 0.007). The discontinuation rates due to AEs were significantly lower with HS (p = 0.006) and ES (p = 0.004) compared to SS. The IR of AEs requiring reduction in the dose of SMX/TMP (p = 0.009) and AEs of special interest (p = 0.003) were different among the three groups with significantly higher IR in SS compared to HS and ES. Conclusions Although there were no PJP cases, the combined group of HS and ES had an excellent estimated non-IR of PJP and both were superior in safety to SS. From the perspective of feasibility and drug discontinuation rates, the daily half-strength regimen was suggested to be optimal for prophylaxis of PJP in patients with systemic rheumatic diseases.

Abstract
Background: Tumor necrosis factor-alpha (TNF-a) is a proinflammatory cytokine that plays an immunomodulatory role in a variety of systemic and dermatologic diseases. Currently, three anti-TNF-a drugs are available in North America— infliximab (approved in the U.S. for the treatment of rheumatoid arthritis, Crohn's disease, ankylosing spondylitis, ulcerative colitis, and psoriatic arthritis), etanercept (approved in the U.S. for the treatment of rheumatoid arthritis, juvenile rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and psoriasis), and adalimumab (approved for the treatment of rheumatoid arthritis and psoriatic arthritis). Objective: To review the current literature supporting alternative (and currently off-label) dermatologic uses of TNF-a antagonists. Methods: A MEDLINE search (1966-March 2005) was conducted using the keywords “infliximab,” “etanercept,” “adalimumab,” “TNF inhibitors,” and “off-label” to identify published reports of off-label dermatologic uses of TNF-a inhibitors. Results: Anti-TNF-a therapies have been reported in the following dermatologic diseases: sarcoidosis, hidradenitis suppuritiva, cicatricial pemphigoid, Behçet's disease, pyoderma gangrenosum, multicentric reticulohistiocytosis, apthous stomatitis, Sneddon-Wilkinson disease, SAPHO syndrome, pityriasis rubra pilaris, eosinophilic fasciitis, Panniculitis, Crohn's disease, necrobiosis lipoidica diabeticorum, dermatomyositis, and scleroderma. The vast majority of these reports are in the form of individual case reports and small case series. Only two published randomized controlled trials involving the off-label use of a TNF inhibitor were found. Conclusions: A growing number of published reports suggest that anti-TNF-a therapies may be effective in the treatment of numerous inflammatory skin diseases outside their currently approved indications.

Abstract
Purpose Demyelinizing neurological disease is a rare complication after treatment with tumor necrosis factor (TNF)α antagonists. We report on a case of multiple sclerosis after TNFα antagonist treatment and discuss its differential diagnosis. Methods This is an observational case study. Results A 48-year-old male was referred to Ophthalmology in January 2015 for an absolute scotoma in the superior quadrant of the visual field in his right eye. Visual acuity was 20/50 in the right eye and 20/20 in the left. Fundus examination was unremarkable bilaterally. Spectral domain optical coherence tomography revealed a normal macular retina structure. Visual field examination revealed a superior hemianopsia in the right eye. Head magnetic resonance imaging showed findings compatible with optic neuritis. The visual evoked potentials confirmed the presence of optic neuritis. The patient had been under therapy with adalimumab since January 2014, for Crohn's disease. Suspension of adalimumab was recommended, and it was substituted with tapered deltacortene, from 1 mg/kg/day. After 1 month, the scotoma was resolved completely. Conclusions TNFα antagonists can provide benefit to patients with inflammatory autoimmune diseases. However, they can also be associated with severe adverse effects. Therefore, adequate attention should be paid to neurological abnormalities in patients treated with TNFα antagonists.

Abstract
Tumor necrosis factor-α (TNF-α) is a cell signalling protein involved in systemic inflammation in infectious and other malignant diseases. Physiologically, it plays an important role in regulating host defence, but its overexpression can lead to serious illnesses including cancer, autoimmune disease and inflammatory disease. Gadolinium-based metallofullerenols, e.g., Gd@C82(OH) x (x ≈ 22), are well known for their abundant biological activities with low toxicity experimentally and theoretically; however, their activity in direct TNF-α inhibition has not been explored. In this work, we investigated the inhibiting effects of four types of fullerene-based ligands: fullerenes, fullerenols, metallofullerenes, and metallofullerenols. We reported previously that fullerenes, metallofullerenes and their hydroxylated derivatives (fullerenols) can reside in the same pocket of the TNF-α dimer as that of SPD304-a known inhibitor of TNF-α [He et al. (2005) Science 310:1022, 18]. Ligand docking and binding free energy calculations suggest that, with a similar nonpolar interaction dominated binding pattern, the fullerene-based ligands, C60, C60(OH)12, Gd@C60, C82, C82(OH)12, Gd@C82, Gd@C82(OH)13 and Gd@C82(OH)21, have larger affinity than currently known inhibitors, and could be used to design novel inhibitors of TNF-α in the future.

Abstract
OBJECTIVE Transforming growth factor β-activated kinase 1 (TAK1) is a key MAPKKK family protein in interleukin-1β (IL-1β), tumor necrosis factor (TNF), and Toll-like receptor signaling. This study was undertaken to examine the posttranslational modification of TAK1 and its therapeutic regulation in rheumatoid arthritis (RA). METHODS The effect of TAK1, IL-1 receptor-associated kinase 1 (IRAK-1), and TNF receptor-associated factor 6 (TRAF6) inhibition was evaluated in IL-1β-stimulated human RA synovial fibroblasts (RASFs). Western blotting, immunoprecipitation, and 20S proteasome assay were used to study the ubiquitination process in RASFs. The efficacy of epigallocatechin-3-gallate (EGCG), a potent antiinflammatory molecule, in regulating these processes in RASFs was evaluated. Molecular docking was performed to examine the interaction of EGCG with human TAK1, IRAK-1, and TRAF6. These findings were confirmed using a rat model of adjuvant-induced arthritis (AIA). RESULTS Inhibition of TAK1, but not IRAK-1 or TRAF6, completely abrogated IL-1β-induced IL-6 and IL-8 synthesis in RASFs. EGCG inhibited TAK1 phosphorylation at Thr(184/187) and occupied the C(174) position, an ATP-binding site, to inhibit its kinase activity. EGCG pretreatment also inhibited K(63) -linked autoubiquitination of TRAF6, a posttranslational modification essential for TAK1 autophosphorylation, by forming a stable H bond at the K(124) position on TRAF6. Furthermore, EGCG enhanced proteasome-associated deubiquitinase expression to rescue proteins from proteasomal degradation. Western blot analyses of joint homogenates from rats with AIA showed a significant increase in K(48) -linked polyubiquitination, TAK1 phosphorylation, and TRAF6 expression when compared to naive rats. Administration of EGCG (50 mg/kg/day) for 10 days ameliorated AIA in rats by reducing TAK1 phosphorylation and K(48) -linked polyubiquitination. CONCLUSION Our findings provide a rationale for targeting TAK1 for the treatment of RA with EGCG.

Abstract
Up to date, in literature, it is still debated the role of anti-tumor necrosis factors (TNF)-α treatments in hepatitis C virus (HCV) patients. TNF-α performs a lot of functions, it is an important pro-inflammatory cytokine and it is involved in the host’s immunity. Since TNF-α is implicated in the apoptotic signaling pathway of hepatocytes infected by HCV, anti TNF-α therapy may increase the risk of viral replication or their reactivation. However the treatment of anti TNF-α could have a healthful role because TNF-α appears to be engaged in the pathogenesis of liver fibrosis, inducing apoptotic pathways. We describe the case of a patient with plaque-type psoriasis and concomitant chronic HCV, who was treated successfully with anti-TNF agents simultaneously to cyclosporine without sign of reactivation of HCV and increase of liver enzymes. Our personal experience shows that anti-TNF-α agents are not only effective but also safe. Furthermore the combination therapy of cyclosporine and anti-TNF-α appears to be well-tolerated and able to reduce the amount of liver enzymes as well as HCV-viral-load. However systematic, large-scale studies with long follow-ups will be needed to confirm our results, in association with close liver function monitoring.

Abstract
Background Nonsteroidal anti-inflammatory drugs are the first-line option for treating ankylosing spondylitis (AS) in China. However, no large-scale controlled trials have been conducted in this ethnic population. Objective To evaluate the efficacy and safety of 6 weeks’ treatment with celecoxib in patients with AS in China. Methods This Phase 3, double-blind, parallel-group study randomized patients with AS aged ≥18 to 65 years 1:1 to receive celecoxib 200 mg once daily or diclofenac sustained release 75 mg once daily. After 6 weeks, patients could use celecoxib 400 mg once daily or maintain blinded therapy. The primary efficacy end point was mean change from baseline at Week 6 for Patient’s Global Assessment of Pain Intensity score (100-mm visual analog scale). Noninferiority was established if the upper bound of the CI was <10 mm. Secondary objectives included patients’ and physicians’ assessments of disease activity, change from baseline in C-reactive protein level, and safety. Results In the per-protocol analysis set the least squares mean change from baseline in the Patient’s Global Assessment of Pain Intensity score at Week 6 was –23.8 mm and –27.1 mm in patients receiving celecoxib (n = 111) and diclofenac (n = 108), respectively. The 2-sided 95% CI for the treatment difference (celecoxib – diclofenac) was –2.2 to 8.8. Overall, 4.2% and 6.7% of patients in the celecoxib and diclofenac groups, respectively, reported treatment-related adverse events. All were mild to moderate in severity. Conclusions Celecoxib 200 mg once daily is noninferior to diclofenac sustained release 75 mg once daily for pain treatment in Chinese patients with AS. ClinicalTrials.gov identifier: NCT00762463.

Abstract
Adalimumab (Humira) is a tumour necrosis factor α (TNFα) inhibitor that is approved for the treatment of rheumatoid arthritis, psoriasis, psoriatic arthritis, Crohn's disease, ankylosing spondylitis, and juvenile idiopathic arthritis (Sullivan and Preda (2009), Klinkhoff (2004), and Medicare Australia). Use of TNFα inhibitors is associated with the induction of autoimmunity (systemic lupus erythematosus, vasculitis, and sarcoidosis or sarcoid-like granulomas) (Ramos-Casals et al. (2010)). We report a patient with extensive psoriasis presenting with renal failure and seropositive lupus markers without classical lupus nephritis after 18 months treatment with adalimumab. He has renal biopsy proven IgA nephritis instead. Renal biopsy is the key diagnostic tool in patients presenting with adalimumab induced nephritis and renal failure. He made a remarkable recovery after adalimumab cessation and steroid treatment. To our knowledge, this is a unique case of a psoriasis patient presenting with seropositive lupus markers without classical lupus nephritis renal failure and had renal biopsy proven IgA glomerulonephritis after receiving adalimumab.

Abstract
OBJECTIVES To investigate the clinical characteristics and risk factors of Pneumocystis jirovecii pneumonia (PCP) in rheumatoid arthritis (RA) patients treated with adalimumab. METHODS We conducted a multicenter, retrospective, case-control study to compare RA patients treated with adalimumab with and without PCP. Data from 17 RA patients who were diagnosed with PCP and from 89 RA patients who did not develop PCP during adalimumab treatment were collected. RESULTS For the PCP patients, the median age was 68 years old, with a median RA disease duration of eight years. The median length of time from the first adalimumab injection to the development of PCP was 12 weeks. At the onset of PCP, the median dosages of prednisolone and methotrexate were 5.0 mg/day and 8.0 mg/week, respectively. The patients with PCP were significantly older (p < 0.05) and had more structural changes (p < 0.05) than the patients without PCP. Computed tomography of the chest revealed ground-glass opacity without interlobular septal boundaries in the majority of the patients with PCP. Three PCP patients died. CONCLUSIONS PCP may occur early in the course of adalimumab therapy in patients with RA. Careful monitoring, early diagnosis, and proper management are mandatory to secure a good prognosis for these patients.

Abstract
The TNF-alpha inhibitors, infliximab (Remicade), etanercept (Enbrel) and adalimumab (Humira) are increasingly being used for chronic inflammatory diseases and have effectively allowed many patients to return to more active lifestyles. The impact of these agents on immune function has led to the recognition of specific infectious complications. The combination of the increasingly active lifestyles of those receiving these agents and their immunosuppressive effects pose new challenges for practitioners of travel medicine. The purpose of this article is to review the immunologic and infectious consequences of these therapies and their potential impact on travelers.

Abstract
OBJECTIVES The association of anti-tumor necrosis factor therapy with opportunistic infections in rheumatoid arthritis (RA) patients has been reported. The goal of this study was to clarify the clinical characteristics and the risk factors of RA patients who developed Pneumocystis jirovecii pneumonia (PCP) during etanercept therapy. METHODS We conducted a multicenter, case-control study in which 15 RA patients who developed PCP were compared with 74 RA patients who did not develop PCP during etanercept therapy. RESULTS PCP developed within 26 weeks following the first injection of etanercept in 86.7% of the patients. All PCP patients presented with a rapid and severe clinical course and the overall mortality was 6.7%. Independent risk factors were identified using multivariate analysis and included age ≥65 years [hazard ratio (HR) 3.35, p = 0.037], coexisting lung disease (HR 4.48, p = 0.009), and concomitant methotrexate treatment (HR 4.68, p = 0.005). In patients having a larger number of risk factors, the cumulative probability of developing PCP was significantly higher (p < 0.001 for patients with two or more risk factors vs. those with no risk factor, and p = 0.001 for patients with one risk factor vs. those with no risk factor). CONCLUSION Physicians must consider the possibility of PCP developing during etanercept therapy in RA patients, particularly if one or more risk factors are present.

Abstract
Use of the biologic agents in moderate to severe chronic plaque psoriasis has provided novel and highly efficacious treatment options. Generally less systemically toxic than more traditional agents, the risks and benefits for these agents must also be considered. We present a review of the iatrogenic effects associated with use of the biologic agents in psoriasis. Focus is placed on antitumor necrosis factor agents, because they are the most studied and commonly used agents, as well as T-cell modulators and interleukin inhibitors.

Abstract
Therapeutic antibodies are antigenically similar to human antibodies and are difficult to detect in assays of human serum samples without the use of the therapeutic antibody's complementary antigen. Herein for the first time, we established a platform to detect Herceptin in solutions by using a small (<2.2 kDa), inexpensive, highly stable human epidermal growth factor receptor (HER2) mimotope-derived synthetic peptide immobilized on the surface of a Au quartz electrode. We used the HER2 mimotope as a substitute for the HER2 receptor protein in piezoimmunosensor or quartz crystal microbalance (QCM) assays to detect Herceptin in human serum. We demonstrated that assay sensitivity was dependent upon the amino acids used to tether and link the peptide to the sensor surface and the buffers used to carry out the assays. The detection limit of the piezoimmunosensor assay was 0.038 nM with a linear operating range of 0.038-0.859 nM. Little nonspecific binding to other therapeutic antibodies (Avastin and Rituxan) was observed. Levels of Herceptin in serum samples obtained from treated patients, as ascertained using the synthetic peptide-based QCM assay, were typical for those treated with Herceptin. The findings of this study are significant in that low-cost synthetic peptides could be used in a QCM assay, in lieu of native or recombinant antigens or capture antibodies, to rapidly detect a therapeutic antibody in human serum. The results suggested that a synthetic peptide bearing a particular functional sequence could be applied for developing a new generation of affinity-based immunosensors to detect a broad range of clinical biomarkers.

Abstract
BACKGROUND AND PURPOSE Fab fragments (Fabs) of antibodies maintain the ability to bind specific antigens, but lack the binding site for complement as well as the site for binding to receptors on effector cells, such as macrophages that play an important role in inflammation. In the present study, we investigated whether Fabs specific for ovalbumin (OVA) were specifically able to suppress anti-OVA antibody-mediated arthritis (AOA-MA) in mice. EXPERIMENTAL APPROACH AOA-MA was induced by i.v. injection of purified anti-OVA antibodies into naïve mice followed by intra-articular (left ankle) challenge with the antigen. Anti-OVA Fabs prepared by digestion of anti-OVA antibodies with papain were injected i.v. immediately after administration of the intact antibodies. Normal Fabs were used as a control. Arthritis was assessed by thickness of the joints (caliper) and by histology of paw sections, stained with haematoxylin and eosin. KEY RESULTS AOA-MA was markedly suppressed by anti-OVA Fabs, but not by control Fabs. Histologically, mice treated with control Fabs showed marked oedema of synovial tissues with a large number of inflammatory cells including neutrophils, whereas animals given anti-OVA Fabs had mild oedema of the synovium and sparse infiltration of such cells. The antigen-specific suppression of joint inflammation by anti-OVA Fabs was associated with reduced consumption of complement. In vitro studies showed that anti-OVA Fabs significantly blocked the binding of intact anti-OVA antibodies to OVA. CONCLUSIONS AND IMPLICATIONS Antibody-mediated arthritis appears to be specifically down-regulated by Fabs that competitively inhibit the binding of antibodies to antigens.

Abstract
Effective treatment with etanercept results from a congregation of immunological signaling and modulating roles played by tumor necrosis factor-alpha (TNF-alpha), a pervasive member of the TNF super-family of cytokines participating in numerous immunologic and metabolic functions. Macrophages, lymphocytes and other cells produce TNF as part of the deregulated immune response resulting in psoriasis or other chronic inflammatory disorders. Tumor necrosis factor is also produced by macrophages and lymphocytes responding to foreign antigens as a primary response to potential infection. Interference with cytokine signaling by etanercept yields therapeutic response. At the same time, interference with cytokine signaling by etanercept exposes patients to potential adverse events. While the efficacy of etanercept for the treatment of psoriasis is evident, the risks of treatment continue to be defined. Of the potential serious adverse events, response to infection is the best characterized in terms of physiology, incidence, and management. Rare but serious events: activation of latent tuberculosis, multiple sclerosis, lymphoma, and others, have been observed but have questionable or yet to be defined association with therapeutic uses of etanercept. The safe use of etanercept for the treatment of psoriasis requires an appreciation of potential adverse events as well as screening and monitoring strategies designed to manage patient risk

Abstract
Rheumatoid arthritis (RA), ankylosing spondylitis (AS) and psoriatic arthritis (PsA) are immune-mediated conditions that share an inflammatory mechanism fuelled by excessive cytokines, particularly TNF. Control of inflammation and rapid suppression of cytokines are important in treating these diseases. With this understanding and the corresponding advent of TNF inhibitors, RA patients, AS patients and PsA patients have found more choices than ever before and have greater hope of sustained relief. As a widely used TNF inhibitor, infliximab has a deep and established record of efficacy and safety data. Extensive evidence - from randomised controlled clinical trials, large registries and postmarketing surveillance studies - shows that infliximab effectively treats the signs and symptoms, provides rapid and prolonged suppression of inflammation, prevents radiologically observable disease progression and offers an acceptable safety profile in RA, AS and PsA. In very recent studies, investigators have observed drug-free remission in some patients. Additionally, infliximab may interfere with rapidly progressing disease in RA by early addition to methotrexate in patients with signs of an aggressive course. Finally, infliximab has been shown to reduce PsA clinical manifestations such as nail involvement. With our current understanding, substantial data and increasing confidence regarding use in practice, infliximab can be considered a well-known drug in our continued campaign against inflammatory rheumatic diseases.

Abstract
The care of inflammatory bowel disease has changed considerably with the introduction of a number of immunosuppressants including anti-metabolite and anti-TNF therapies. While efficacious, these medications also carry important risks, notably the potential risk of lymphoma. This risk is one of the most worrisome for both patients and physicians. Our current knowledge is still evolving; however, our understanding of what risks these drugs carry, both individually and synergistically, is critical in allowing informed decision making. In this article, we will describe the known lymphoma risks of commonly used immunosuppressant medications in inflammatory bowel disease, with an emphasis on non-Hodgkin's lymphoma and hepatosplenic T-cell lymphoma.

Abstract
Tumor necrosis factor alpha (TNF-alpha) is an inflammatory cytokine that is released by a variety of cell types, including immune effector cells and tissue-specific cells. TNF-alpha has been shown to promote inflammation via the activation and induction of cytokines interleukin 1 (IL-1), IL-6, and IL-8 and by the upregulation of adhesion molecules on endothelial cells leading to increased leukocyte extravasation. Theoretically, the blockade of TNF should have widespread potential in the treatment of numerous inflammatory diseases. Currently, 3 TNF-alpha inhibitors available in the United States are approved for psoriasis and psoriatic arthritis: infliximab, etanercept, and adalimumab. Numerous case reports and case series have been published in recent years reporting the off-label uses of these drugs in various inflammatory skin diseases. This review summarizes the most recent reports on 20 such conditions.

Abstract
BACKGROUND It has been postulated that the time to onset of adverse drug reactions is connected to the underlying pharmacological (or toxic) mechanism of adverse drug reactions whether the reaction is time dependent or not. OBJECTIVE We have conducted a preliminary study using the parametric modelling of the time to onset of adverse reactions as an approach to signal detection on spontaneous reporting system databases. METHODS We performed a parametric modelling of the reported time to onset of adverse drug reactions for which the underlying toxic mechanism is characterized. For the purpose of our study, we have used the reported liver injuries associated with bosentan, and the infections associated with the use of the tumour necrosis factor (TNF) inhibitors, adalimumab, etanercept and infliximab, which are used in Crohn's disease and rheumatoid arthritis, reported to EudraVigilance between December 2001 and September 2006. RESULTS The main results reflect the fact that the reported time to onset is a surrogate of the true time to onset of the reaction and combines three hazards (occurrence, diagnosis and reporting) that cannot be disentangled. Consequently, the modelling of the time to onset of reactions reported with TNF inhibitors showed differences that could reflect different pharmacological activities, indications, monitoring of the patients or different reporting patterns. These variations could also limit the interpretation of the parametric modelling. CONCLUSIONS Some consistency that was found between the occurrences of the infections with the TNF inhibitors suggests a causal association. There are statistical issues that are important to keep in mind when interpreting the results (the impact of the data quality on the fit of the distributions and the absence of a test of hypothesis linked to the absence of a relevant comparator). The study suggests that the modelling of the reported time to onset of adverse reactions could be a useful adjunct to other signal detection methods.

Abstract
Systemic lupus erythematosus (SLE) is mainly a disease of fertile women and the coexistence of pregnancy is by no means a rare event. How SLE and its treatment affects pregnancy outcome is still a matter of debate. Assessment of the reciprocal clinical impact of SLE and pregnancy was investigated in a cohort study. We reviewed the clinical features, treatment, and outcomes of 43 pregnant SLE patients with 51 pregnancies followed from 1993 to 2007 at a tertiary university hospital. The age of patients was 28.7 +/- 5.4 years and SLE was diagnosed at age of 23.0 +/- 6.1 years. Previous manifestations of SLE included lupus nephritis (14 patients) and secondary antiphospholipid syndrome (11 patients). Thirty-five pregnant patients (69%) were in remission for more than 6 months at the onset of pregnancy. Patients were being treated with low doses of prednisone (29), hydroxychloroquine (20), azathioprine (five), acetylsalicylic acid (51), and low molecular weight heparin (13). Sixteen pregnancy-associated flares were documented, mainly during the second trimester (42%) and also in the following year after delivery (25%). Renal involvement was found in 11 cases (68%). Spontaneous abortion occurred in 6%, 16% had premature deliveries, and 74% were delivered at term. No cases of maternal mortality occurred. No cases of fetal malformation were recorded. There was one intrauterine fetal death and one neonatal death at 24 gestational weeks. Pregnant women with SLE are high risk patients, but we had a 90% success rate in our cohort. A control disease activity strategy to target clinical remission is essential.

Abstract
Anti-tumor necrosis factor alpha (TNF-alpha) drugs have been successfully used for the treatment of rheumatic autoimmune diseases including rheumatoid arthritis (RA), psoriatic arthritis, psoriasis, ankylosing spondylitis (AS), juvenile chronic arthritis, and Crohn's disease. However, they have been associated with different neurological disorders, including alterations of peripheral nerves, multiple sclerosis (MS), optic neuritis (ON) and acute transverse myelitis (ATM). This article reviews the most current aspect regarding neurological adverse events associated with anti-TNF-alpha drugs with emphasis on the possible explanations for this relation and the pathogenic mechanism of TNF-alpha in neurological disorders.

Abstract
This article describes the cancer risks of commonly used inflammatory bowel disease (IBD) medications, with an emphasis on hematologic malignancy risks. The increasing use of immunosuppressant therapies in the treatment of IBD has raised this question to an even greater importance. Studies evaluating these medications are complicated due to varying disease severity and concomitant use of other immunosuppressant medication. The potential risks of all therapies must be weighed against the benefits these therapies can offer these patients.

Abstract
As the average age of mothers is increasing there is a greater likelihood that they will have intercurrent medical problems at the time of their pregnancy. As a group, autoimmune diseases are relatively common with an estimated population prevalence of 5-8%. At least 75% of autoimmune diseases occur in women, most frequently during the child-bearing years. Rheumatoid arthritis (RA) is the most common chronic inflammatory disease of joints and occurs in approximately 1% of the population with women being affected two or three times more than men and many of the women being of child-bearing age. The pathogenesis of RA is multifactorial with a role for T-lymphocytes, B-lymphocytes, macrophages and other pro-inflammatory cells producing a plethora of cytokines including interleukin-1 and tumour necrosis factor-α in the synovial cavity resulting in irreversible damage to cartilage, soft tissues and bone.(1) The drug treatment of RA involves the use of disease-modifying agents to reduce or prevent permanent tissue damage. There is a new class of drugs that can be used to target specific cells and cytokines that have been called 'biological agents'. These drugs have been shown to significantly reduce inflammation and to retard the progression of joint damage in RA thereby reducing symptoms and improving function.(2).
