Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by progressive joint inflammation, resulting in cartilage destruction and bone erosion. It was reported that low-dose radiation modulates immune disease. Here, we investigated whether low-dose whole-body irradiation has preventive and therapeutic effects in collagen-induced RA (CIA) mouse models. Fractionated low-dose irradiation (0.05 Gy/fraction, total doses of 0.1, 0.5 or 0.8 Gy) was administered either concurrently with CIA induction by Type II collagen immunization (preventive) or after CIA development (therapeutic). The severity of CIA was monitored using two clinical parameters, paw swelling and redness. We also measured total Immunoglobulin G (IgG) and inflammatory cytokines (interleukine (IL)-6, IL-1β and tumor necrosis factor-alpha (TNF-α)) in the serum by enzyme-linked immunosorbent assay, and we evaluated histological changes in the ankle joints by immunohistochemistry and hematoxylin and eosin staining. Low-dose irradiation reduced CIA clinical scores by up to 41% in the preventive model and by 28% in the therapeutic model, while irradiation in the preventive model reduced the typical CIA incidence rate from 82 to 56%. In addition, low-dose irradiation in the preventive model decreased total IgG by up to 23% and decreased IL-1β and TNF-α by 69 and 67%, and in the therapeutic model, decreased total IgG by up to 35% and decreased IL-1β and IL-6 by 59 and 42% with statistical significance (P < 0.01, 0.05 and 0.001). Our findings demonstrate that low-dose radiation has preventive and therapeutic anti-inflammatory effects against CIA by controlling the immune response, suggesting that low-dose radiation may represent an alternative therapy for RA, a chronic degenerative immune disease.

Abstract
BACKGROUND Myelin oligodendrocyte glycoprotein-associated disorders (MOGAD) is an autoimmune central nervous system disease. Antigen-specific immune tolerance using nanoparticles such as Polylactic-co-glycolic acid (PLGA) have recently been used as a new therapeutic tolerization approach for CNS autoimmune diseases. We examined whether MOG1-125 conjugated with PLGA could induce MOG-specific immune tolerance in an experimental autoimmune encephalitis (EAE) mouse model. EAE was induced in sixty C57BL/6 J wild-type mice using MOG1-125 peptide with complete Freund's Adjuvant. The mice were divided into 12 groups (n = 5 each) to test the ability of MOG1-125 conjugated PLGA intervention to mitigate the severity or improve the outcomes from EAE with and without rapamycin compared to antigen alone or PLGA alone. EAE score and serum MOG-IgG titers were compared among the interventions.Kindly check and confirm the processed Affiliation “4” is appropriate.I confirmed the Aff 4.Affiliation: Corresponding author information have been changed to present affiliation. Kindly check and confirm.I checked and confirmed the Corresponding author's information. RESULTS Mice with EAE that were injected intraperitoneally with MOG1-125 conjugated PLGA + rapamycin complex showed dose-dependent mitigation of EAE score. Intraperitoneal and intravenous administration resulted in similar clinical outcomes, whereas 80% of mice treated with subcutaneous injection had a recurrence of clinical score worsening after approximately 1 week. Although there was no significant difference in EAE scores between unconjugated-PLGA and MOG-conjugated PLGA, serum MOG-IgG tended to decrease in the MOG-conjugated PLGA group compared to controls. CONCLUSION Intraperitoneal administration of PLGA resulted in dose-dependent and longer-lasting immune tolerance than subcutaneous administration. The induction of immune tolerance using PLGA may represent a future therapeutic option for patients with MOGAD.

Abstract
An 80-year-old woman with rheumatoid arthritis during treatment with etanercept, a tumor necrosis factor (TNF) inhibitor, showed swelling of the salivary glands and retroperitoneal fibrosis, which was diagnosed as IgG4-related disease. Although some reports have shown the efficacy of TNF inhibitors for IgG4-related disease or retroperitoneal fibrosis, TNF inhibitors sometimes cause paradoxical reactions like psoriasis, and the mechanisms are considered to involve the upregulation of plasmacytoid dendritic cells and IFN-α, which is also common in patients with IgG4-related disease. This is a case report of IgG4-related retroperitoneal fibrosis with the possibility of a rare paradoxical reaction by a TNF inhibitor.

Abstract
INTRODUCTION Abdominal aortic aneurysm (AAA) is a multifactorial, degenerative disease characterized by progressive aortic dilation and chronic activation of inflammation, proteolytic activity, and oxidative stress in the aortic wall. The immune response triggered by antibodies against antigens present in the vascular wall participates in the formation and progression of AAA through mechanisms not completely understood. This work analyses the function of specific IgG receptors (FcγR), especially those expressed by monocytes/macrophages, in the development of experimental AAA. METHODS In the elastase-induced AAA model, the abdominal aortas from wildtype and FcγR deficient mice with/without macrophage adoptive transfer were analysed by histology and quantitative PCR. In vitro, mouse macrophages were transfected with RNA interference of FcγRIV/CD16.2 or treated with Syk kinase inhibitor before stimulation with IgG immune complexes. RESULTS Macrophage adoptive transfer in FcγR deficient mice increased the susceptibility to AAA development. Mice receiving macrophages with functional FcγR exhibited higher aortic diameter increase, higher content of macrophages and B lymphocytes, and upregulated expression of chemokine CCL2, cytokines (TNF-α and IL-17), metalloproteinase MMP2, prooxidant enzyme NADPH oxidase-2, and the isoforms FcγRIII/CD16 and FcγRIV/CD16.2. In vitro, both FcγRIV/CD16.2 gene silencing and Syk inhibition reduced cytokines and reactive oxygen species production induced by immune complexes in macrophages. CONCLUSIONS Activation of macrophage FcγR contributes to AAA development by inducing mediators of inflammation, proteolysis, and oxidative stress. Modulation of FcγR or effector molecules may represent a potential target for AAA treatment.

Abstract
BACKGROUND Regdanvimab has decreased the time to clinical recovery from coronavirus disease 2019 (COVID-19) and lowered the rate of oxygen therapy according to the results from phase 2/3 randomized controlled trial. More information is needed about the effects and safety of regdanvimab. METHODS We analyzed data for patients with high-risk mild or moderate COVID-19 being admitted to Busan Medical Center between December 1, 2020 and April 16, 2021. A propensity score (PS) matched analysis was conducted to compare patients treated with and without regdanvimab. The primary outcome was in-hospital death or disease aggravation which means the need for oxygen therapy (low- or high-flow oxygen therapy and mechanical ventilation) and secondary outcomes comprised the length of hospital stay and adverse reactions. RESULTS Among 1,617 selected patients, 970 (60.0%) were indicated for regdanvimab. Of these, 377 (38.9%) were administered with regdanvimab. Among a 1:1 PS-matched cohort of 377 patients each treated with and without regdanvimab, 19 (5%) and 81 (21.5%) reached the composite outcome of death, or disease aggravation, respectively (absolute risk difference, -16.4%; 95% confidence interval [CI], -21.1, -11.7; relative risk difference, 76.5%; P < 0.001). Regdanvimab significantly reduced the composite outcome of death, or disease aggravation in univariate (odds ratio [OR], 0.194; 95% CI, 0.112-0.320; P < 0.001) and multivariable-adjusted analyses (OR, 0.169; 95% CI, 0.095-0.289; P < 0.001). The hospital stay was shorter for the group with than without regdanvimab. Some hematological adverse reactions were more frequent in the group without regdanvimab, but other adverse reactions did not significantly differ between the groups. CONCLUSION Regdanvimab was associated with a significantly lower risk of disease aggravation without increasing adverse reactions.

Abstract
BACKGROUND Expressed on activated T and natural killer cells, 4-1BB/CD137 is a costimulatory receptor that signals a series of events resulting in cytokine secretion and enhanced effector function. Targeting 4-1BB/CD137 with agonist antibodies has been associated with tumor reduction and antitumor immunity. C-C chemokine receptor 4 (CCR4) is highly expressed in various solid tumor indications and associated with poor prognosis. This phase Ib, open-label study in patients with advanced solid tumors assessed the safety, efficacy, pharmacokinetics, and pharmacodynamics of utomilumab (PF-05082566), a human monoclonal antibody (mAb) agonist of the T-cell costimulatory receptor 4-1BB/CD137, in combination with mogamulizumab, a humanized mAb targeting CCR4 reported to deplete subsets of regulatory T cells (Tregs). METHODS Utomilumab 1.2-5 mg/kg or 100 mg flat dose every 4 weeks plus mogamulizumab 1 mg/kg (weekly in Cycle 1 followed by biweekly in Cycles ≥2) was administered intravenously to 24 adults with solid tumors. Blood was collected pre- and post-dose for assessment of drug pharmacokinetics, immunogenicity, and pharmacodynamic markers. Baseline tumor biopsies from a subset of patients were also analyzed for the presence of programmed cell death-ligand 1 (PD-L1), CD8, FoxP3, and 4-1BB/CD137. Radiologic tumor assessments were conducted at baseline and on treatment every 8 weeks. RESULTS No dose-limiting toxicities occurred and the maximum tolerated dose was determined to be at least 2.4 mg/kg per the time-to-event continual reassessment method. No serious adverse events related to either treatment were observed; anemia was the only grade 3 non-serious adverse event related to both treatments. Utomilumab systemic exposure appeared to increase with dose. One patient with PD-L1-refractory squamous lung cancer achieved a best overall response of partial response and 9 patients had a best overall response of stable disease. No patients achieved complete response. Objective response rate was 4.2% (95% confidence interval: 0.1-21.1%) per RECIST 1.1. Depletion of Tregs in peripheral blood was accompanied by evidence of T-cell expansion as assessed by T-cell receptor sequence analysis. CONCLUSIONS The combination of utomilumab/mogamulizumab was safe and tolerable, and may be suitable for evaluation in settings where CCR4-expressing Tregs are suppressing anticancer immunity.

Abstract
Objective To investigate the long-term safety and efficacy of weekly subcutaneous IgPro20 (Hizentra, CSL Behring) in chronic inflammatory demyelinating polyneuropathy (CIDP). Methods In a 48-week open-label prospective extension study to the PATH study, patients were initially started on 0.2 g/kg or on 0.4 g/kg weekly and-if clinically stable-switched to 0.2 g/kg weekly after 24 weeks. Upon CIDP relapse on the 0.2 g/kg dose, 0.4 g/kg was (re)initiated. CIDP relapse was defined as a deterioration by at least 1 point in the total adjusted Inflammatory Neuropathy Cause and Treatment score. Results Eighty-two patients were enrolled. Sixty-two patients initially received 0.4 g/kg, 20 patients 0.2 g/kg weekly. Seventy-two received both doses during the study. Sixty-six patients (81%) completed the 48-week study duration. Overall relapse rates were 10% in 0.4 g/kg-treated patients and 48% in 0.2 g/kg-treated patients. After dose reduction from 0.4 to 0.2 g/kg, 51% (27/53) of patients relapsed, of whom 92% (24 of 26) improved after reinitiation of the 0.4 g/kg dose. Two-thirds of patients (19/28) who completed the PATH study without relapse remained relapse-free on the 0.2 g/kg dose after dose reduction in the extension study. Sixty-two patients had adverse events (AEs) (76%), of which most were mild or moderate with no related serious AEs. Conclusions Subcutaneous treatment with IgPro20 provided long-term benefit at both 0.4 and 0.2 g/kg weekly doses with lower relapse rates on the higher dose. Long-term dosing should be individualized to find the most appropriate dose in a given patient. Classification of evidence This study provides Class IV evidence that for patients with CIDP, long-term treatment with SCIG beyond 24 weeks is safe and efficacious.

Abstract
IgG4-related diseases (IgG4-RDs) have recently been reported in many organs other than the salivary, pancreatic and hepatobiliary systems. A 64-year-old woman was referred to our department for her abdominal fullness and cardiomegaly on chest X-ray. After draining the pericardial fluid, her symptom promptly diminished, and pericardial friction rubbing became clearly audible. Elevated serum levels of IgG and IgG4 and ureteral wall thickening on computed tomography suggested IgG4-RD. After the initiation of oral corticosteroid therapy, the pericardial effusion was resolved, and she has been in a steady-state condition for the past two years.

Abstract
Hypophysitis is a rare entity characterized by inflammation of the pituitary gland and its stalk that can cause hypopituitarism and/or mass effect. Etiology can be categorized as primary or secondary to systemic disease, but may also be classified according to anatomical and hispathological criteria. Newly recognized causes of hypophysits have been described, mainly secondary to immunomodulatory medications and IgG4-related disease. Diagnosis is based on clinical, laboratory and imaging data, whereas pituitary biopsy, though rarely indicated, may provide a definitive histological diagnosis. For the clinician, obtaining a broad clinical and drug history, and performing a thorough physical examination is essential. Management of hypophysitis includes hormone replacement therapy if hypopituitarism is present and control of the consequences of the inflammatory pituitary mass (e.g. compression of the optic chiasm) using high-dose glucocorticoids, whereas pituitary surgery is reserved for those unresponsive to medical therapy and/or have progressive disease. However, there remains an unmet need for controlled studies to inform clinical practice.

Abstract
Background Anti-neutrophil cytoplasmic antibody associated vasculitis (AAV) is a typical disease of the elderly. In AAV, there is an age-specific increase in disease incidence with age being a predictor of disease outcome. In this study, we aimed to determine the contribution of age to the development of AAV employing a mouse model of anti-myeloperoxidase (MPO) antibody-mediated glomerulonephritis. Methods Anti-MPO IgG and lipopolysaccharide (LPS)-mediated glomerulonephritis was induced in 3- and 18-month-old C57Bl6 mice. Clinical and pathological parameters of disease severity, alterations in the immune system and kidney specific changes in these mice were evaluated. Results Eighteen-month-old mice developed increased disease severity upon injection of anti-MPO IgG/LPS compared with 3-month-old mice. This was evidenced by increased albuminuria, more extensive glomerular capillary necrosis and increased glomerular neutrophil accumulation. Glomerular crescent formation was mild in both young and old mice. Old mice displayed higher plasma interleukin-6 levels as well as higher proportions of circulating neutrophils and activated monocytes compared with young mice. In addition, renal mRNA levels of inflammatory genes and endothelial adhesion molecules were higher in 18-month-old mice compared with 3-month-old mice. Conclusion In conclusion, our results indicate that aged mice develop more severe clinical and pathological disease upon induction of anti-MPO IgG/LPS-mediated glomerulonephritis. These findings may be attributed to age-related changes in the immune system as well as in the kidney itself.

Abstract
OBJECTIVE Hypophosphatasia (HPP) is a rare skeletal disease characterized by hypomineralization and low alkaline phosphatase activity. Asfotase alfa (AA) has been recently developed to treat HPP complications. This study evaluated its safety and efficacy in Japan. DESIGN Open-label, multicentre, prospective trial. Patients were enrolled in 11 hospitals from June 2014 to July 2015. PATIENTS Thirteen patients (9 females, 4 males) ages 0 days to 34 years at baseline were enrolled and treated with AA (2 mg/kg three times weekly subcutaneously in all but one patient). All had ALPL gene mutations. HPP forms were perinatal (n=6), infantile (n=5), childhood (n=1) and adult (n=1). MEASUREMENTS Safety determined from adverse events (AEs) and laboratory data was the primary outcome measure. Efficacy was assessed as a secondary outcome measure from overall survival, respiratory status, rickets severity and gross motor development. RESULTS Injection site reactions were the most frequent AEs. Serious AEs possibly related to treatment were convulsion and hypocalcaemia observed in a patient with the perinatal form. In addition, hypercalcaemia and/or hyperphosphatemia was observed in three patients with the infantile form and a low-calcium and/or low-phosphate formula was given to these patients. With respect to efficacy, all patients survived and the radiographic findings, developmental milestones and respiratory function improved. CONCLUSION Asfotase alfa therapy improved skeletal, respiratory and physical symptoms with a few serious AEs in patients with HPP. Our results add support to the safety and efficacy of AA therapy for HPP patients.

Abstract
Retroperitoneal fibrosis (RPF) is a rare disease characterised by fibrous tissue proliferation in the retroperitoneum, with encasement of the ureters and large vessels of the abdomen as the most destructive of potentially severe complications. It can either be idiopathic, or secondary to infections, malignancies, or the use of certain drugs. The idiopathic form accounts for approximately 75% of the cases, and is usually responsive to immunosuppressive therapy. In recent years, the emergence of a new clinical entity, IgG4-related disease (IgG4-RD), shed light on many fibro-inflammatory disorders once thought to be separate clinical entities, although frequently associated in the so-called multifocal fibrosclerosis. Among these, together with sclerosing pancreatitis and cholangitis, pseudotumour of the orbit, idiopathic mediastinal fibrosis and other conditions, is idiopathic retroperitoneal fibrosis (IRF). Both IRF and IgG4-RD can be associated with a wide variety of disorders, usually governed by immune-mediated (and particularly auto-immune) mechanisms. In our review, we discuss the clinical and therapeutic challenges IRF presents to the internist, as well as the meaning of its recent inclusion in the IgG4-RD spectrum from a clinical practice standpoint.

Abstract
The clinical picture of IgG4-related disease (IgG4-RD) is diverse because various organs can be affected. We describe the case of a 56-year-old man with acute renal failure and tuberoinfundibular hypophysitis due to IgG4-RD. Steroid therapy lowered the serum IgG4 level and ameliorated renal dysfunction, bilateral hydronephrosis and retroperitoneal fibrosis. However, polyuria from post-obstructive diuresis and unmasked central diabetes insipidus ensued. The patient's polyuria continued despite the administration of a therapeutic dose of glucocorticoid; the patient's pituitary swelling and anterior pituitary dysfunction were partially ameliorated. The pituitary swelling recurred seven months later. In patients with IgG4-RD, the manifestation of polyuria after steroid therapy should prompt suspicion of post-obstructive diuresis and the unmasking of central diabetes insipidus.

Abstract
The aim of this work was to estimate the efficacy and safety of single intramuscular introduction of specific heterologous immunoglobulin as prophylactic drug against Ebola hemorrhagic fever. Materials and methods. The specific heterologous immunoglobulin was introduced as a special prophylactic drug to 28 patients in epidemic situations, after skin hurt with infectious materials or contact with infectious blood. Clinico-laboratory observation was performed in 24 subjects after single intramuscular introduction of heterologous immunoglobulin Ebola. The samples of blood serum were investigated for immunoglobulin Ebola and antibodies to horse gamma-globulin on the 30th and 60th days after prophylaxis. Results. None of the subjects of the study contracted Ebola fever. There were no anaphylactic reactions after special prophylaxis with specific heterologous immunoglobulin. Among the subjects with normal allergic state 31% responded with local reactions; 13%, with a general reaction (mild case of the serum disease). Almost no reaction was observed in patients with unfavorable allergic state subjected to desensitizing therapy; in the absence of desensitizing therapy, 50% of patients with unfavorable allergic state exhibited local reactions; 17%, mild cases of the serum disease; 33%, moderate cases of the serum disease. In summary, if the tactics of immunoglobulin application was right, the quantity of local allergic reactions was 28%; of wide spread reactions, 6%. Weak serum disease was observed in 11% of the subjects. The prognostic period of resistance to Ebola fever was less than 30 days. Conclusion. The prophylactic use of specific immunoglobulin from horse blood serum against hemorrhagic Ebola fever is effective and relatively safe in patients subjected to desensitizing therapy.

Abstract
Objective: To report a case of parapharyngeal abscess associated with Streptococcus viridans in a patient with rheumatoid arthritis receiving treatment with etanercept. Case Summary: A 40-year-old man diagnosed with rheumatoid arthritis had received treatment with nonsteroidal antiinflammatory drugs, methotrexate, and deflazacort. Six months prior to admission, the patient had a Disease Activity Score of 3.4; clinicians decided to start treatment with etanercept. Chest X-rays were normal and the tuberculin skin test was negative. Treatment with etanercept plus methotrexate was started. Three months later, methotrexate was discontinued. Six months after etanercept therapy was started, the patient presented to our emergency department with a swelling of his neck, odynophagia, otalgia, and trismus. The clinical course was consistent with parapharyngeal abscess. Etanercept treatment was suspended. The parapharyngeal abscess was drained and intravenous methylprednisolone, amoxicillin/clavulanic acid, and clindamycin were administered. The parapharyngeal abscess secretion culture was positive for S. viridans and Bacteroides spp. The patient's condition improved with antibiotic therapy; he was discharged 5 days after admission. Discussion: Tumor necrosis factor-α plays an essential role in the immune-mediated response to infection. In our patient, the most possible cause of parapharyngeal abscess was considered to be etanercept because of the temporal relationship between exposure to the drug and onset of symptoms. Etanercept was the only drug administered before the abscess developed. Based on the Naranjo probability scale, an association between etanercept and the adverse reaction could be considered possible. Conclusions: Patients initiated on etanercept therapy should be closely monitored for the development of tuberculosis and other infections. During treatment, all febrile or novel illnesses should be evaluated promptly. If clinical evaluation leads to the suspicion of tuberculosis and other infections associated with etanercept, it should be discontinued immediately.

Abstract
BACKGROUND Daclizumab is a humanized monoclonal antibody against CD25 that modulates interleukin 2 signaling. The SELECT TRILOGY of clinical studies (SELECT/SELECTION/SELECTED) evaluated the safety and efficacy of daclizumab in patients with relapsing-remitting multiple sclerosis (RRMS). We report the long-term safety and efficacy of daclizumab 150 mg subcutaneous every 4 weeks in patients with RRMS in the SELECTED open-label extension study. METHODS An interim intent-to-treat analysis of all enrolled patients was performed in January 2014 for this ongoing study. RESULTS The SELECTED study enrolled 90% of patients who completed SELECTION. In the safety and efficacy analysis (N = 410), median treatment time in SELECTED was 25 months (range, <1-45). Adverse events (AEs) were reported in 76% of patients, serious AEs (SAEs) excluding MS relapse in 16%, and treatment discontinuation due to AEs including multiple sclerosis (MS) relapse in 12%. AEs were primarily of mild to moderate severity, and common AEs (≥10%), excluding MS relapse, were nasopharyngitis (12%) and upper respiratory tract infection (12%). Most commonly reported SAEs (in ≥3 patients), excluding MS relapses, were increased serum hepatic enzymes, pneumonia, ulcerative colitis, and urinary tract infection (<1% each). Incidences of AE groups of interest include cutaneous events (28%), cutaneous SAEs (2%), gastrointestinal SAEs (2%), hepatic SAEs, (1%) and malignancies (1%). The incidence of AEs, SAEs, and treatment-related study discontinuations did not increase over time and no deaths were reported. The adjusted annualized relapse rate (95% confidence interval (CI)) analyzed at 6-month intervals was 0.15 (0.10-0.22) for weeks 97-120 and 0.15 (0.10-0.21) for weeks 121-144. In year 3, the adjusted mean (95% CI) number of new/newly enlarging T2 hyperintense lesions was 1.26 (0.93-1.72) and the mean (median) annualized change in brain volume was -0.32% (-0.34%). CONCLUSIONS The AE incidence did not increase with extension of therapy into year 3 in SELECTED; the safety profile was similar to that previously observed. The clinical efficacy of daclizumab was sustained over the 3 years comprising the SELECT TRILOGY, although potential selection bias cannot be excluded.

Abstract
We report one case of pregnancy-onset severe diffuse proliferative nephritis in a patient with systemic lupus erythematosus (SLE), who was successfully treated with a combination of anti-tumour necrosis factor (TNF)-alpha, plasmapheresis and high-dose intravenous gammaglobulin. No flares were observed either in clinical symptoms or in laboratory examinations during pregnancy or after delivery. Her autoantibodies except fluorescent anti-nuclear antibodies were negative. We suggest that a combination of anti-TNF-alpha, plasmapheresis and high-dose intravenous gammaglobulin may be a safe and effective therapy for pregnant patients suffering severe lupus nephritis.

Abstract
PURPOSE The novel dual-action humanized IgG1 antibody MEHD7945A targeting HER3 and EGFR inhibits ligand-dependent HER dimer signaling. This phase I study evaluated the safety, pharmacokinetics, pharmacodynamics, and antitumor activity of MEHD7945A. EXPERIMENTAL DESIGN Patients with locally advanced or metastatic epithelial tumors received escalating doses of MEHD7945A (1-30 mg/kg) every 2 weeks (q2w) until disease progression or intolerable toxicity. An expansion cohort was enrolled at the recommended phase II dose (14 mg/kg, q2w). Plasma samples, tumor biopsies, FDG-PET were obtained for assessment of pharmacokinetics, and pharmacodynamic modulation downstream of EGFR and HER3. RESULTS No dose-limiting toxicities or MEHD7945A-related grade ≥ 4 adverse events (AE) were reported in dose-escalation (n = 30) or expansion (n = 36) cohorts. Related grade 3 AEs were limited to diarrhea and nausea in the same patient (30 mg/kg). Related AEs in ≥20% of patients ≤24 hours after the first infusion included grade 1/2 headache, fever, and chills, which were managed with premedication and/or symptomatic treatment. Pharmacodynamic data indicated target inhibition in 25% of evaluable patients. Best response by RECIST included 2 confirmed partial responses in squamous cell carcinomas of head and neck (SCCHN) patients with high tumor tissue levels of the HER3 ligand heregulin; 14 patients had stable disease ≥8 weeks, including SCCHN (n = 3), colorectal cancer (n = 6), and non-small cell lung cancer (n = 3). CONCLUSIONS MEHD7945A was well-tolerated as single agent with evidence of tumor pharmacodynamic modulation and antitumor activity in SCCHN. Phase II studies were initiated with flat (nonweight-based) dosing at 1,100 mg q2w in SCCHN and colorectal cancer.

Abstract
BACKGROUND Daclizumab high-yield process (HYP) is a humanized monoclonal antibody that binds to CD25 (alpha subunit of the interleukin-2 receptor) and modulates interleukin-2 signaling. Abnormalities in interleukin-2 signaling have been implicated in the pathogenesis of multiple sclerosis and other autoimmune disorders. METHODS We conducted a randomized, double-blind, active-controlled, phase 3 study involving 1841 patients with relapsing-remitting multiple sclerosis to compare daclizumab HYP, administered subcutaneously at a dose of 150 mg every 4 weeks, with interferon beta-1a, administered intramuscularly at a dose of 30 μg once weekly, for up to 144 weeks. The primary end point was the annualized relapse rate. RESULTS The annualized relapse rate was lower with daclizumab HYP than with interferon beta-1a (0.22 vs. 0.39; 45% lower rate with daclizumab HYP; P<0.001). The number of new or newly enlarged hyperintense lesions on T2-weighted magnetic resonance imaging (MRI) over a period of 96 weeks was lower with daclizumab HYP than with interferon beta-1a (4.3 vs. 9.4; 54% lower number of lesions with daclizumab HYP; P<0.001). At week 144, the estimated incidence of disability progression confirmed at 12 weeks was 16% with daclizumab HYP and 20% with interferon beta-1a (P=0.16). Serious adverse events, excluding relapse of multiple sclerosis, were reported in 15% of the patients in the daclizumab HYP group and in 10% of those in the interferon beta-1a group. Infections were more common in the daclizumab HYP group than in the interferon beta-1a group (in 65% vs. 57% of the patients, including serious infection in 4% vs. 2%), as were cutaneous events such as rash or eczema (in 37% vs. 19%, including serious events in 2% vs. <1%) and elevations in liver aminotransferase levels that were more than 5 times the upper limit of the normal range (in 6% vs. 3%). CONCLUSIONS Among patients with relapsing-remitting multiple sclerosis, daclizumab HYP showed efficacy superior to that of interferon beta-1a with regard to the annualized relapse rate and lesions, as assessed by means of MRI, but was not associated with a significantly lower risk of disability progression confirmed at 12 weeks. The rates of infection, rash, and abnormalities on liver-function testing were higher with daclizumab HYP than with interferon beta-1a.

Abstract
Multiple subcutaneous immunoglobulin (SCIG) products are available to treat primary antibody deficiency (PAD). The efficacy and tolerability of 16% SCIG (Vivaglobin(®) ) was compared with 20% SCIG (Hizentra(®) ) in PAD subjects. The study was a prospective, single-centre, open-label study of PAD subjects transitioning Vivaglobin to equivalent Hizentra doses, rounded to the nearest vial size. Comparisons included immunoglobulin (Ig)G levels; tetanus, varicella and Streptococcus pneumoniae titres; adverse events (AEs), annual infection rate and quality of life during 8 weeks of Vivaglobin and 24 weeks of Hizentra. Thirty-two subjects (aged 2-75 years) participated. Rounding to the nearest Hizentra vial size resulted in a 12·8% (± 2·9%) increase in SCIG dose. Median immunoglobulin (Ig)G level following 8 weeks of Vivaglobin was similar to 24 weeks of Hizentra (1050 versus 1035 mg/dl, respectively; P = 0·77). Both products had similar protective titres to tetanus, varicella and serotypes of S. pneumoniae, which were variable but well above protective levels. After 12 weeks of Hizentra, subjects reported fewer local site reactions compared with Vivaglobin. Switching products resulted in increased systemic AEs in some subjects but, overall, not significantly higher than during Vivaglobin treatment. Average infusion time decreased from 104·7 min (3·3 sites) with Vivaglobin to 70·7 min (2·2 sites) with Hizentra (P = 0·0005). Acute serious bacterial infections were similar. Treatment satisfaction was superior with Hizentra. Hizentra and Vivaglobin have similar pharmacokinetics and efficacy. Although transition to a different SCIG product initially increased AEs, Hizentra is well tolerated and can be infused more rapidly and with fewer sites compared to Vivaglobin.

Abstract
CONTEXT In X-linked hypophosphatemia (XLH), elevated fibroblast growth factor 23 (FGF23) decreases the renal tubular maximum reabsorption rate of phosphate/glomerular filtration rate (TmP/GFR) and serum inorganic phosphorus (Pi), resulting in rickets and/or osteomalacia. OBJECTIVE The objective was to test the hypothesis that monthly KRN23 (anti-FGF23 antibody) would safely improve serum Pi in adults with XLH. DESIGN Two sequential open-label phase 1/2 studies were done. SETTING Six academic medical centers were used. PARTICIPANTS Twenty-eight adults with XLH participated in a 4-month dose-escalation study (0.05-0.6 mg/kg); 22 entered a 12-month extension study (0.1-1 mg/kg). INTERVENTION KRN23 was injected sc every 28 days. MAIN OUTCOME MEASURE The main outcome measure was the proportion of subjects attaining normal serum Pi and safety. RESULTS At baseline, mean TmP/GFR, serum Pi, and 1,25-dihydroxyvitamin D [1,25(OH)2D] were 1.6 ± 0.4 mg/dL, 1.9 ± 0.3 mg/dL, and 36.6 ± 14.3 pg/mL, respectively. During dose escalation, TmP/GFR, Pi, and 1,25(OH)2D increased, peaking at 7 days for TmP/GFR and Pi and at 3-7 days for 1,25(OH)2D, remaining above (TmP/GFR, Pi) or near [1,25(OH)2D] pre-dose levels at trough. After each of the four escalating doses, peak Pi was between 2.5 and 4.5 mg/dL in 14.8, 37.0, 74.1, and 88.5% of subjects, respectively. During the 12-month extension, peak Pi was in the normal range for 57.9-85.0% of subjects, and ≥25% maintained trough Pi levels within the normal range. Serum Pi did not exceed 4.5 mg/dL in any subject. Although 1,25(OH)2D levels increased transiently, mean serum and urinary calcium remained normal. KRN23 treatment increased biomarkers of skeletal turnover and had a favorable safety profile. CONCLUSIONS Monthly KRN23 significantly increased serum Pi, TmP/GFR, and 1,25(OH)2D in all subjects. KRN23 has potential for effectively treating XLH.

Abstract
OBJECTIVES The purpose of this analysis was to examine discontinuation and reasons for discontinuation from disease-modifying anti-rheumatic (DMARD) therapies in the RADIUS 2 registry, a long-term, open-label, observational study of patients with moderate to severe rheumatoid arthritis (RA). METHODS Patients who participated in RADIUS 2 initiated etanercept (ETN) therapy at study entry and were followed for 5 years. In this post hoc analysis, patients who had received ETN continuously from entry to month 4 were categorised by treatment at month 4: ETN monotherapy, ETN+methotrexate (MTX), ETN+MTX+other DMARDs (OTH), or ETN+OTH. Outcomes were assessed at month 4 and at the time of any subsequent treatment change, and included Clinical Disease Activity Index (CDAI) and Health Assessment Questionnaire Disability Index (HAQ-DI). RESULTS Of 3,484 patients analysed (982 ETN; 1,356 ETN+MTX; 537 ETN+MTX+OTH; 609 ETN+OTH), baseline demographic and clinical characteristics were similar across treatments. No treatment change occurred in 62.3%, 49.9%, 33.3%, and 37.1% of ETN, ETN+MTX, ETN+MTX+OTH, and ETN+OTH patients, respectively. The mean time on therapy from month 4 was longer for patients receiving ETN (23.3 months) or ETN+MTX (23.7 months) than those receiving ETN+MTX+OTH (18.0 months) or ETN+OTH (18.3 months). The greatest improvements in CDAI and HAQ-DI were seen in patients who continued on ETN. The most common reasons for discontinuing DMARD therapy were cost and ineffective treatment. CONCLUSIONS Most patients who had received ≥4 months of ETN continued on ETN throughout the 5-year observation period. Patients with greatest clinical and disability improvements tended to continue on ETN.

Abstract
Therapeutic immunoglobulin G (IgG) products are produced from numerous plasma donations, and are infused in many medical conditions. The serological testing of patients who have received IgG infusions may well produce falsely positive and misleading results from this infused IgG, rather than endogenously produced IgG. We present two example cases of clinical situations where this could cause concern. We tested multiple IgG products with a range of serological tests performed in infective or autoimmune conditions, including hepatitis B, syphilis, human immunodeficiency virus, human T-lymphotropic virus, anti-neutrophil cytoplasmic antibody (ANCA), anti-nuclear antibody (ANA), anti-cardiolipin antibodies and anti-double stranded DNA (dsDNA) antibody. We found positivity within these products for hepatitis B surface and core antibody, syphilis, ANCA, ANA, anti-cardiolipin IgG and dsDNA antibody, which may result from specific or non-specific reactivity. The serological testing of patients who have received IgG treatment detects the administered IgG in addition to IgG produced by the patient.

Abstract
PURPOSE This phase I study aimed to establish the biologic effects and MTD of the agonistic IgG1 chimeric anti-CD40 antibody ChiLob7/4 in patients (pts) with a range of CD40-expressing solid tumors and diffuse large B-cell lymphoma, resistant to conventional therapy. Potential mechanisms of action for agonistic anti-CD40 include direct cytotoxic effects on tumor cells and conditioning of antigen-presenting cells. EXPERIMENTAL DESIGN ChiLob7/4 was given by IV infusion weekly for 4 doses at a range from 0.5 to 240 mg/dose. Validated ELISAs were used to quantify ChiLob7/4 in serum and test for anti-chimeric MAb (HACA) responses. Pharmacodynamic assessments included quantitation of T-cell, natural killer-cell, and B-cell numbers and activation in blood by flow cytometry and a panel of cytokines in plasma by Luminex technology. Planned dose escalation was in cohorts of 3 patients until MTD or biologic effect, defined as reduction of peripheral blood CD19(+) B cells to 10% or less of baseline. RESULTS Twenty-nine courses of treatment were given to 28 subjects. The MTD was 200 mg × 4, with dose-limiting toxicity of liver transaminase elevations at 240 mg. At 200 mg (range between 2.1 mg/kg and 3.3 mg/kg based on patient body weight), the trough level pretreatment was above 25 μg/mL. Grade 1-2 infusion reactions were seen above the dose of 16 mg, but could be prevented with single-dose corticosteroid premedication. HACA responses were seen after doses between 1.6 mg and 50 mg, but not above this. There were dose-dependent falls in blood B-cell numbers accompanied by reduced expression of CD21, and transient reductions in NK cell numbers with increased CD54 expression from 50 mg upward. MIP-1β and IL12 plasma concentrations rose after doses above 16 mg. Fifteen of 29 treatments were accompanied by disease stabilization for a median 6 months, the longest for 37 months. CONCLUSIONS ChiLob7/4 can activate B and NK cells at doses that can be administered safely, and should be tested in combination with other antibodies and chemotherapy agents.

Abstract
PURPOSE To establish the pharmacokinetics and safety of single-dose polyclonal caprine anti-HIV antibodies ((PE)HRG214)in HIV-1-infected individuals. DESIGN A phase 1, open-label, nonrandomized, dose-escalating study. METHOD HIV-1-infected patients with CD4+ T-cell counts of < or =200 cells/microL and plasma HIV viral load (VL)of > or =5,000 copies/mL received a single intravenous dose of HRG. Dosing began at 6,000 U/kg HRG with proposed step-wise escalation to 96,000 U/kg. RESULTS Eleven males were enrolled; median CD4+T-cell count and VL were 96 cells/microL and 126,200 copies/mL, respectively. HRG exhibited linear pharmacokinetics across the dosing range studied. The mean terminal elimination half-life (t(1/2)) was 136.6 +/- 44.6 hours (range, 52.6-198 h). Serum sickness occurred in one 48,000 U/kg HRG recipient. One 6,000 U/kg and two 24,000 U/kg HRG recipients developed a mild rash. Between baseline and day 60, VL remained unchanged (n = 6), increased by 0.67 log(10) copies/mL (n = 1), or declined by 0.34-1.55 log(10) copies/mL (n = 4). CONCLUSION Single-dose HRG exhibited linear kinetics and a long half-life. Although numbers in each dosing group were very small (n = 3), HRG was generally well tolerated in doses below 48,000 U/kg. Multiple dosing with HRG in the HIV-salvage setting may be complicated by immune-complex formation.

Abstract
OBJECTIVES This prospective long-term follow-up study evaluated the effects of half-dose etanercept (25 mg weekly) on clinical remission and radiographic progression in a large cohort of patients with rheumatoid arthritis (RA) in clinical remission after etanercept 25 mg bi-weekly. METHODS 524 biologic-naïve RA patients were treated with etanercept 25 mg bi-weekly after failure of conventional drugs. Patients achieving remission (DAS28 <2.6) for ≥12 months were randomised to receive etanercept 25 mg weekly or 25 mg bi-weekly. Patients were assessed at baseline and every 12 weeks. Remission rates, radiographic progression, incidence of infections and costs of the regimens were compared. RESULTS After a mean follow-up of 18±11 months, 347 patients (66.2%) achieved DAS28 remission; 323 were randomised to one of two dose regimens: etanercept 25 weekly (group A, 159 patients) and etanercept 25 mg bi-weekly (group B, 164 patients). At the end of follow-up, 81.8% patients of group A maintained remission for a mean of 3.6±1.5 years. Radiographic progression occurred in a small number of patients of group A and the rate of radiographic progression (TSS >0) was not significantly different in the two groups (18.85% vs. 19.0% after the first year and 16.9% vs. 21.6% after the second year, respectively). The incidence ratio of severe infections was 2.3/1.000 patient-years in group A. Etanercept half-dose regimen resulted in a saving of €3.190.545 with a cost saving up to €827.318 per year. CONCLUSIONS Clinical remission and arrest of radiographic progression persisted in a substantial percentage of patients with RA even after reduction of standard-dose etanercept.

Abstract
OBJECTIVES The present paper aims to investigate the effect of psoriatic arthritis (PsA) disease duration on the outcome of treatment with etanercept (ETN) in patients with PsA who also have moderate-to-severe psoriasis. METHODS Patients from the PRESTA trial who received ≥1 ETN 50 mg once weekly (QW) dose and had ≥1 post-baseline value were evaluated. Baseline and after-treatment changes were compared between patients with PsA ≤2 years versus PsA >2 years in efficacy measures (physician global assessment [PGA] arthritis, swollen joint count and Psoriasis Area and Severity Index [PASI]) and patient reported outcomes (PROs; joint pain, arthritis activity, Euro-Qol [EQ-5D] utility and visual analogue score [VAS]) using linear regression analysis. RESULTS Baseline efficacy measures were similar between the PsA ≤2 years (n=103) and PsA >2 years (n=269) groups, with the exception of PGA arthritis (p=0.006). At week 24, improvements in efficacy measures were observed in both groups but were significantly greater for PGA arthritis in the PsA ≤2 years group (p=0.03). Quality of life (QoL), measured using PROs, was generally lower at baseline in patients with PsA >2 years. Clinically meaningful improvements were seen in QoL with ETN treatment in both groups, but the change from baseline scores at week 24 were significantly higher in PsA ≤2 years group for joint pain (p=0.007), arthritis activity (p=0.01), EQ-5D utility (p=0.046) and EQ-5D VAS (p=0.04) responses. CONCLUSIONS PsA patients responded to ETN 50 mg QW treatment irrespective of disease duration; however, patients with shorter PsA duration had greater improvements in arthritis scores and several PRO measures.

Abstract
Cyclosporine is an established therapy for psoriasis that provides rapid relief of symptoms but has long-term toxic side effects. The objective of this study was to demonstrate the efficacy of etanercept as replacement therapy for cyclosporine in patients with moderate-to-severe plaque psoriasis. Patients with plaque psoriasis were given cyclosporine 5 mg/kg/day until achievement of PASI50 at which point cyclosporine was tapered to 0 over 6 weeks. At week 6, patients were randomised (1:1) to receive etanercept (50 mg/week) or placebo for an additional 24 weeks. Patients in the etanercept group (n = 58) experienced a reduction of -1.1 in mean PASI score (p = 0.233 vs. cyclosporine) at week 30; patients in the placebo group (n = 62) had mean PASI increase of 3.7 (p < 0.001 vs. cyclosporine). The incidence of patients reporting any adverse events was not significant between groups (77% etanercept, 74% placebo; p = 0.675). Etanercept demonstrated higher efficacy and good tolerability as replacement therapy for cyclosporine in plaque psoriasis.

Abstract
BACKGROUND We assessed the effects of reduction and withdrawal of treatment in patients with rheumatoid arthritis who had a remission while receiving etanercept-plus-methotrexate therapy. METHODS Patients with early active disease who had not previously received methotrexate or biologic therapy received 50 mg of etanercept plus methotrexate weekly for 52 weeks (open-label phase). We then randomly assigned patients who had qualifying responses at weeks 39 and 52 to receive 25 mg of etanercept plus methotrexate (combination-therapy group), methotrexate alone, or placebo for 39 weeks (double-blind phase). Patients who had qualifying responses at week 39 of the double-blind phase had all treatment withdrawn at that time and were followed to week 65 (treatment-withdrawal phase). The primary end point was the proportion of patients with sustained remission in the double-blind phase. RESULTS Of 306 patients enrolled, 193 underwent randomization in the double-blind phase; 131 qualified for the treatment-withdrawal phase. More patients in the combination-therapy group than in the methotrexate-alone group or the placebo group met the criterion for the primary end point (40 of 63 [63%] vs. 26 of 65 [40%] and 15 of 65 [23%], respectively; P=0.009 for combination therapy vs. methotrexate alone; P<0.001 for combination therapy vs. placebo). At 65 weeks, 28 patients (44%) who had received combination therapy, 19 (29%) who had received methotrexate alone, and 15 (23%) who had received placebo were in remission (P=0.10 for combination therapy vs. methotrexate alone; P=0.02 for combination therapy vs. placebo; P=0.55 for methotrexate alone vs. placebo). No significant between-group differences were observed in radiographic progression of disease. Serious adverse events were reported in 3 patients (5%) in the combination-therapy group, 2 (3%) in the methotrexate-alone group, and 2 (3%) in the placebo group. CONCLUSIONS In patients with early rheumatoid arthritis who had a remission while receiving full-dose etanercept-plus-methotrexate therapy, continuing combination therapy at a reduced dose resulted in better disease control than switching to methotrexate alone or placebo, but no significant difference was observed in radiographic progression.

I've been taking methotrexate for my rheumatoid arthritis (RA) for several years, but it doesn't seem to be helping my symptoms. My doctor suggested adding a biologic response modifier (BRM) drug, such as etanercept (Enbrel) or adalimumab (Humira) to my treatment plan, but I've heard that BRMs can increase cancer risk.

Abstract
AIM To describe the features of chronic sinusitis associated with the use of tumour necrosis factor (TNF) inhibitors. METHODOLOGY A retrospective review of the medical records between 2003 and 2011 revealed that five patients had developed chronic sinusitis after the start of TNF inhibitor administration and required rhinological evaluation and treatment. RESULTS The incidence of refractory sinusitis associated with TNF inhibitors was approximately 2%. Of the five patients identified, four patients were medicated with etanercept and one with infliximab. The maxillary sinus was most commonly involved and cultures of the sinus discharge revealed Pseudomonas aeruginosa in three cases. Two patients showed improvement of sinusitis with antibiotic medication, despite the continuous use of TNF inhibitor, while in two other patients, sinusitis was resistant to antibiotic medication. Another patient who had developed recurrence of sinusitis after complete remission of previous chronic sinusitis by endoscopic sinus surgery showed remission only after cessation of TNF inhibitor. CONCLUSION Chronic sinusitis associated with TNF inhibitors is considered to be a new disease entity, and it will become more common due to the increasing use of TNF inhibitors.

Abstract
Neuromyelitis optica (NMO) is an autoimmune demyelinating disease of the central nervous system in which binding of anti-aquaporin-4 (AQP4) autoantibodies (NMO-IgG) to astrocytes causes complement-dependent cytotoxicity (CDC) and inflammation resulting in oligodendrocyte and neuronal injury. There is compelling evidence for a central role of complement in NMO pathogenesis. Here, we evaluated the potential of C1-esterase inhibitor (C1-inh) for complement-targeted therapy of NMO. C1-inh is an anti-inflammatory plasma protein with serine protease inhibition activity that has a broad range of biological activities on the contact (kallikrein), coagulation, fibrinolytic and complement systems. C1-inh is approved for therapy of hereditary angioedema (HAE) and has been studied in a small safety trial in acute NMO relapses (NCT 01759602). In vitro assays of NMO-IgG-dependent CDC showed C1-inh inhibition of human and rat complement, but with predicted minimal complement inhibition activity at a dose of 2000 units in humans. Inhibition of complement by C1-inh was potentiated by ∼10-fold by polysulfated macromolecules including heparin and dextran sulfate. In rats, intravenous C1-inh at a dose 30-fold greater than that approved to treat HAE inhibited serum complement activity by <5%, even when supplemented with heparin. Also, high-dose C1-inh did not reduce pathology in a rat model of NMO produced by intracerebral injection of NMO-IgG. Therefore, although C1r and C1s are targets of C1-inh, our in vitro data with human serum and in vivo data in rats suggest that the complement inhibition activity of C1-inh in serum is too low to confer clinical benefit in NMO.

Abstract
OBJECTIVES To determine the risk of serious infection in patients with rheumatoid arthritis (RA) receiving etanercept (ETN) or disease-modifying anti-rheumatic drugs (DMARDs) and to identify factors that predict a higher risk. METHODS Five-year data from the British Society of Rheumatology Biologics Register (BSRBR), a prospective observational study of patients with active RA treated with ETN, were used. These data were compared with a cohort of patients receiving DMARDs with active RA. RESULTS Total follow-up was 19,964 patient-years (py; ETN, 14,381 py; DMARDs, 5583 py). Over the study period, 651 first-recorded serious infections were reported (ETN, 469 [39.9 per 1000 py]; DMARDs, 182 [35.0 per 1000 py]). Overall the risk of serious infection was similar for the 2 treatments; however, in the first 6 months of treatment the hazard ratio (HR) was higher in the ETN than the DMARD group (1.979; p=0.015). A linear association was observed between the serious infection rate and disease-activity score in 28 joints (DAS28) in patients from each treatment group and overall (DAS28 <4, 27.1 per 1000 py; DAS28 ≥8, 64.4 per 1000 py; 7.5% increase in serious infection for each unit increase of DAS28 score at baseline). In a time-dependent analysis, a DAS28 change of 1 unit during follow-up predicted a 27% increase in serious infection rates. CONCLUSIONS No significant increase in the risk of serious infection was observed with ETN versus DMARDs over the 5-year study; a linear relationship existed between the serious infection rate and disease activity, as measured by DAS28.

Abstract
BACKGROUND/AIMS The treatment for steroid-refractory acute graft versus host disease (GVHD) after allogeneic stem cell transplantation (allo-SCT) needs to be standardized. We report our clinical experience with etanercept for steroid-refractory acute GVHD. METHODS Eighteen patients who underwent allo-SCT and presented with steroid-refractory acute GVHD at Ajou University Hospital were studied retrospectively. They were given 25 mg of etanercept subcutaneously twice weekly for 4 weeks. The clinical responses were evaluated with regard to the severity of acute GVHD. RESULTS The median patient age was 43.5 years. Using nonparametric tests, etanercept had a down-grading effect on acute GVHD (p = 0.005), although no patient experienced complete remission. Partial responses were seen in 80%, 17%, and 57% of grade II to IV patients, respectively. Skin and gut GVHD were well controlled with etanercept, whereas hepatic GVHD was not. Four patients died of fatal infections. No factors affecting the clinical outcome of etanercept were identified. CONCLUSIONS Etanercept has a modest effect on steroid-refractory acute GVHD after allo-SCT, with tolerable side effects.

Abstract
OBJECTIVES Biological therapy represents important advances in alleviating rheumatoid arthritis (RA), but the effect on interstitial lung disease (ILD) has been controversial. The objective of this study was to assess the risk of such treatment for patients with ILD. DESIGN Case-control cohorts. SETTING Single centre in Japan. PARTICIPANTS This study included 163 patients with RA who underwent biological therapy. OUTCOME MEASURED We assessed chest CT before initiation of biological therapy and grouped 163 patients according to the presence of ILD (with (n=58) and without pre-existing ILD (n=105)). Next, we evaluated serial changes of chest CT after treatment and visually assessed the emergence of ILD or its progression, which was referred to as an 'ILD event'. Then, we also classified the patients according to the presence of ILD events and analysed their characteristics. RESULTS Tumour necrosis factor (TNF) inhibitors were administered to more patients with ILD events than those without ILD events (88% vs 60%, p<0.05), but recipients of tocilizumab or abatacept did not differ in this respect. Of 58 patients with pre-existing ILD, 14 had ILD events, and that proportion was greater than for those without pre-existing ILD (24% vs 3%, p<0.001). Of these 14 patients, all were treated with TNF inhibitors. Four patients developed generalised lung disease and two died from ILD progression. Baseline levels of KL-6 were similar in both groups, but increased in patients with ILD events. CONCLUSIONS TNF inhibitors have the potential risk of ILD events, particularly for patients with pre-existing ILD, and KL-6 is a valuable surrogate marker for detecting ILD events. Our data suggest that non-TNF inhibitors are a better treatment option for these patients.

Abstract
An 88-year-old woman with rheumatoid arthritis who had started etanercept treatment in July 2011 was referred to our hospital in February 2012 for right-sided pleural effusion. Chest computed tomography showed right pleural effusion, partial swelling of a calcified mediastinal lymph node, and mid-esophageal thickening of the mucosal wall. Gastroendoscopy showed mid-esophageal ulceration. Histological examination of biopsy specimens from this ulceration revealed noncaseating granulomas with Langhans giant cells. Ziehl-Neelsen staining of this section was positive for acid-fast bacilli. Polymerase chain reaction analysis of gastric juice was positive for Mycobacterium tuberculosis; we therefore diagnosed the patient with esophageal tuberculosis. However, since abdominal computed tomography showed swelling of mesenteric lymph nodes, we also suspected intestinal tuberculosis. Colonoscopy showed multiple ileal erosions; histological analyses of biopsied specimens revealed granulomas with Langhans giant cells, similar to the esophageal findings. We finally diagnosed the patient with both esophageal and intestinal tuberculosis. After anti-tuberculosis treatment, the right pleural effusion disappeared and the abdominal lesions improved. Although mycobacterial involvement of both the esophagus and intestine is rare in immunocompromised and immunocompetent hosts, differential diagnosis of these diseases is likely to become more important.

Abstract
BACKGROUND Interleukin-17A is considered to be central to the pathogenesis of psoriasis. We evaluated secukinumab, a fully human anti-interleukin-17A monoclonal antibody, in patients with moderate-to-severe plaque psoriasis. METHODS In two phase 3, double-blind, 52-week trials, ERASURE (Efficacy of Response and Safety of Two Fixed Secukinumab Regimens in Psoriasis) and FIXTURE (Full Year Investigative Examination of Secukinumab vs. Etanercept Using Two Dosing Regimens to Determine Efficacy in Psoriasis), we randomly assigned 738 patients (in the ERASURE study) and 1306 patients (in the FIXTURE study) to subcutaneous secukinumab at a dose of 300 mg or 150 mg (administered once weekly for 5 weeks, then every 4 weeks), placebo, or (in the FIXTURE study only) etanercept at a dose of 50 mg (administered twice weekly for 12 weeks, then once weekly). The objective of each study was to show the superiority of secukinumab over placebo at week 12 with respect to the proportion of patients who had a reduction of 75% or more from baseline in the psoriasis area-and-severity index score (PASI 75) and a score of 0 (clear) or 1 (almost clear) on a 5-point modified investigator's global assessment (coprimary end points). RESULTS The proportion of patients who met the criterion for PASI 75 at week 12 was higher with each secukinumab dose than with placebo or etanercept: in the ERASURE study, the rates were 81.6% with 300 mg of secukinumab, 71.6% with 150 mg of secukinumab, and 4.5% with placebo; in the FIXTURE study, the rates were 77.1% with 300 mg of secukinumab, 67.0% with 150 mg of secukinumab, 44.0% with etanercept, and 4.9% with placebo (P<0.001 for each secukinumab dose vs. comparators). The proportion of patients with a response of 0 or 1 on the modified investigator's global assessment at week 12 was higher with each secukinumab dose than with placebo or etanercept: in the ERASURE study, the rates were 65.3% with 300 mg of secukinumab, 51.2% with 150 mg of secukinumab, and 2.4% with placebo; in the FIXTURE study, the rates were 62.5% with 300 mg of secukinumab, 51.1% with 150 mg of secukinumab, 27.2% with etanercept, and 2.8% with placebo (P<0.001 for each secukinumab dose vs. comparators). The rates of infection were higher with secukinumab than with placebo in both studies and were similar to those with etanercept. CONCLUSIONS Secukinumab was effective for psoriasis in two randomized trials, validating interleukin-17A as a therapeutic target.

Abstract
Tumor necrosis factor α antagonists are potent biologics used to treat a variety of autoimmune disorders such as rheumatoid arthritis, ankylosing spondylitis, Crohn disease, psoriasis, and psoriatic arthritis. These medications are known to have many side effects (eg, infusion reactions, cytopenia, risk for infection, heart failure); however, only a few cases of acne vulgaris have been associated with the use of these biologics, particularly infliximab and adalimumab. We report a rare case of etanercept-induced cystic acne.

Abstract
Alopecia areata (AA) is a complication of biologic therapy with several anti-tumor necrosis factor (TNF) inhibitors and efalizumab for the treatment of various autoimmune diseases. We report the case of a 51-year-old woman who developed AA universalis while undergoing treatment with daclizumab, an immunosuppressive biologic therapy, administered for treatment of inflammatory ocular disease. Although immunomodulatory agents that function by interfering with T helper cell stimulation are expected to impede autoimmune-related processes, we believe that daclizumab may be causally related to the development of AA.
