Abstract
Systemic immunosuppressants and biologicals have been a valuable tool in the
treatment of inflammatory diseases and malignancies. The safety profile of these
drugs has been debatable, especially in localized systems, such as the eye. This
has led to the search for fairly local approaches, such as intravitreal,
subconjunctival, and topical route of administration. Immunosuppressants have
been used as a second-line drug in patients intolerable to corticosteroids or
those who develop multiple recurrences on weaning corticosteroids. Similarly,
biologicals have also been used as the next line of therapy, when adequate
control of inflammation could not be attained or immunosuppressants were
contraindicated to patients. Intravitreal immunosuppressants, such as
methotrexate and sirolimus, have been extensively studied in noninfectious
posterior uveitis, whereas limited studies have established the efficacy of
intravitreal biologicals, such as infliximab and adalimumab. Most of these drugs
have shown good safety profile and tolerability in animal studies alone and have
not been studied further in human subjects. However, most of the studies in
literature are single-case reports or case series which limits the level of
evidence. In this comprehensive review, we discuss the mechanism of action,
pharmacodynamics, pharmacokinetics, indications, efficacy, and side effects of
different intravitreal immunosuppressants and biologicals that have been studied
in literature.

Abstract
The new era of immune and reconstitution therapy of autoimmune disorders is ongoing. However, endocrine autoimmune diseases comprise a group of elaborating pathologies where the development of new treatment strategies remains slow. Substitution of the missing hormones is still standard practice, taking care of the devastating symptoms but not the cause of disease. As our knowledge of the genetic contribution to the aetiology of endocrine disorders increases and early diagnostic tools are available, it is now possible to identify persons at risk before they acquire full-blown disease. This review summarizes current knowledge and treatment of endocrine autoimmune disorders, focusing on type 1 diabetes, Addison's disease, autoimmune thyroid diseases and primary ovarian insufficiency. We explore which new therapies might be used in the different stages of the disease, focus on legalized therapy and elaborate on the ongoing clinical studies for these diseases and the research front, before hypothesizing on the way ahead.

Abstract
INTRODUCTION The advent, more than two decades ago, of monoclonal antibodies and soluble receptors targeting tumor necrosis factor (TNF)-α has revolutionized the therapeutic approach to otherwise difficult-to-treat autoimmune and inflammatory diseases. However, due to the pleiotropic functions played by this pro-inflammatory cytokine (with particular relevance in granuloma maintenance), TNF-α blockade may increase the incidence of serious infections. Areas covered: The present review summarizes the biological rationale supporting the impact of anti-TNF-α therapy on the host's susceptibility to infection. The structure, mode of action, and indications of available agents are reviewed, as well as the clinical evidence coming from clinical trials and observational registries. We discuss the impact of patient- and disease-related factors influencing the occurrence of infection. Finally, strategies for risk minimization are also covered, with particular attention to recommendations for screening of latent tuberculosis infection and management of chronic hepatitis B infection. Expert commentary: Methodological limitations (confounding by indication bias, patient dropout, or switching therapies) should be considered when interpreting observational data. Clinicians must individualize the infection risk assessment not only on the basis of the specific anti-TNF-α agent used or the expected duration of therapy, but also by taking into account the baseline susceptibility of a given patient.

Abstract
Purpose Biosimilar IFX (CT-P13) received marketing approval in Turkey for treatment of rheumatologic diseases, including ankylosing spondylitis, psoriatic arthritis, rheumatoid arthritis (RA), inflammatory bowel disease (IBD), and psoriasis. Population data on real-world treatment patterns of CT-P13 following marketing approval in European countries are largely unreported. This study examined the prescribing and medication utilization patterns of innovator infliximab (IFX) and CT-P13 in Turkey for patients with RA or IBD naïve to either IFX. Materials and methods Adult patients with ≥1 diagnosis claim for RA or IBD and ≥1 claim for IFX or CT-P13 were identified in the Turkish Ministry of Health database during the following identification periods: 1 Oct 2014–30 May 2015 (RA) and 1 Oct 2014–31 Dec 2015 (IBD). Continuous medical and pharmacy coverage for ≥12 months before and after the date of the first dose (index) IFX or CT-P13 was also required. Separate analyses were done for each population. Results Seven hundred and seventy nine adult RA and 581 IBD patients met the selection criteria. The majority of RA (74%; n=575) and IBD patients (87%; n=504) were initiated on IFX. The average study observation period was 16 months for the RA and 12 months for the IBD population. Over the observation periods, discontinuation among RA patients occurred in 42% of IFX and 63% of CT-P13 while discontinuation in the IBD cohort occurred in 38% of IFX; and 62% of CT-P13. Conclusion In this population-based study, more IFX-naïve RA and IBD patients were initially treated with IFX than CT-P13. Discontinuation and switching were observed more often and earlier among patients treated with CT-P13 regardless of disease state. Further studies are needed to understand the reasons for these observed differences.

Abstract
The present study aimed to investigate the potential clinical value of three-dimensional gait analysis (3D-GA) system in evaluating ankylosing spondylitis (AS). Thirty-one patients with AS from September 2010 to August 2011, with 32 involved and 30 uninvolved lower limbs, were enrolled. Data of spatio-temporal parameters (step and stride length, velocity and cadence), time parameters (stance, single stance, double stance and swing phases) and kinematics parameters associated with spinal mobility (spinal lateral bending, spinal forward bending and spinal rotation) were analyzed by 3D-GA system, as well as curative effects of biologic therapy. Compared with normal values, AS patients showed decreased step and stride length ([Formula: see text]), increased cadence, longer swing and single stance phases ([Formula: see text]) and shorter stance and double stance phases ([Formula: see text]) in uninvolved lower limbs. In AS patients, reduced step length, stride length, velocity and cadence, shorter swing and single stance phases, longer stance and double stance phases ([Formula: see text]), increased lateral bending angle and decreased spinal rotation ([Formula: see text]) were detected by 3D-GA in involved lower limbs compared with uninvolved ones. In the 16 patients with decreased levels of ESR and CRP and improved ASAS scores after biology therapy, increased step length, stride length, velocity and cadence of the involved lower limbs were detected by 3D-GA ([Formula: see text]), as well as improved spinal mobility ([Formula: see text]). Hence, we concluded that 3D-GA has great potential value of clinical application for assessing and monitoring AS.

Abstract
Low back pain (LBP) is one of the most common and costly medical conditions in the United States; various studies have reported up to 80% of the adult population will experience a significant episode of LBP sometime within their lifetime. Although many cases of LBP are related to the musculoskeletal system and appropriate for the care of the physical therapist (PT), some episodes of LBP have a systemic cause. Thus, it is the role of the PT to ensure each patient is appropriate for physical therapy intervention throughout the episode of care. When the patient's condition is not appropriate for physical therapy intervention, it is the PT's responsibility to refer the patient to other medical professions to ensure optimal patient care. The purpose of this case report is to describe a patient referred to PT who was diagnosed with ankylosing spondylitis. The patient presented initially to physical therapy with a diagnosis of LBP. However, after several visits her symptoms were inconsistent with mechanical LBP and thus required further medical consultation.

Abstract
Tumor necrosis factor-alpha (TNFalpha) is a key proinflammatory cytokine involved in chronic inflammatory diseases. Infliximab, a chimeric (human-murine) monoclonal IgG1 anti-TNFalpha antibody, is used in the treatment of Crohn's disease (including fistulising disease) and rheumatoid arthritis (in combination with methotrexate) if standard treatments have failed. The indications for infliximab have recently been expanded to include ankylosing spondylitis, psoriatic arthritis, psoriasis and ulcerative colitis. The biological agent infliximab is given by multiple intravenous infusions in a dosage of 3-5 mg/kg (initially at weeks 0, 2 and 6; subsequently in intervals of 4-8 weeks). In controlled trials, clinical response rates of 20-40% have been achieved with such regimens in Crohn's disease and rheumatoid arthritis. However, the therapeutic benefits must be balanced against the risks of a variety of severe adverse events (e.g. severe infections including tuberculosis, hepatotoxicity, infusion reactions, serum sickness-like disease and lymphoma). Following single and multiple infusions of infliximab, no relevant differences in median concentration-time profiles have been observed between patients with Crohn's disease, patients with rheumatoid arthritis and patients with psoriasis. The apparent volume of distribution of the high-molecular-weight infliximab (149.1 kDa) is low (3-6L) and represents the intravascular space. The long persistence in this compartment (elimination half-life 7-12 days, mean residence time 12-17 days) is due to the very low systemic clearance of about 11-15 mL/hour (0.18-0.25 mL/minute). Elimination of infliximab is most probably accomplished through degradation by unspecific proteases. During multiple infusions (every 4-8 weeks), no accumulation was observed, and serum concentrations and the area under the plasma concentration-time curve of infliximab increased in proportion to the infused dose, indicating linear pharmacokinetics. Co-medication with methotrexate delayed the decline in the serum concentrations of infliximab. When relating serum concentrations to the clinical response in patients with rheumatoid arthritis and patients with Crohn's disease, it can be assumed that trough concentrations above 1 microg/mL could be used as a kind of therapeutic target. In the future, identification of biomarkers for (non-)response and risk factors for adverse drug reactions would be very helpful. Furthermore, combined biological, pharmacokinetic, pharmacogenomic and clinical studies have not yet been performed and are needed to optimise the therapeutic potential of infliximab, which is currently established as a rescue treatment in refractory patients.

Abstract
The recent introduction of infliximab, a chimeric monoclonal antibody against tumor necrosis factor-alpha, has greatly modified the treatment of Crohn's disease (CD). Data from the literature show encouraging results after intravenous infusion both for closure of intestinal or perianal fistulas and for induction and maintenance of remission in patients with moderate to severe intestinal disease unresponsive to other treatments. However, some contraindications such as fibrostenosing CD and sepsis have been identified. In addition, the data on long-term outcomes and safety is still limited. Our initial experience showed that in selected cases local injection of infliximab is effective in the treatment of complex perianal disease offering the possibility of using such treatment even in small bowel obstructing disease with minimal systemic effects. This paper analyzes the state of the use of both intravenous and local injection of infliximab in patients with CD.

Abstract
Our aim was to investigate the efficacy, toxicity, and drug discontinuation in patients with ankylosing spondylitis (AS) treated with infliximab. Thirty-five patients with AS, who were enrolled between June 2001 and December 2002 were treated with infliximab. All patients fulfilled the New York revised criteria for AS and had axial disease. Infliximab (5 mg/kg weight), was given intravenously at weeks 0, 2, 6, and every 8 weeks thereafter. If this failed to give an acceptable treatment response, the interval was shortened to 6 or 4 weeks. The patients were followed-up at predefined times according to a standardized protocol. Data concerning infliximab efficacy, tolerability, adverse events, interval, and drug discontinuation were all recorded. Clinical improvement according to the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) 50% and the Ankylosing Spondylitis Assessment Study group (ASAS) 40%, and ASAS 5/6 response criteria were recorded. Infliximab treatment resulted in a rapid improvement in the BASDAI and ASAS scores in the first year of the treatment, which sustained throughout the fourth year. More specifically, after the third year of treatment 17/35 (48.6%) of patients achieved BASDAI 50% response criteria, 19/35 (54.3%) attained the ASAS 40% and 15/35 (42.9%) reached the ASAS 5/6. After the fourth year of treatment BASDAI 50% was reached by 17/35 (48.6%) of patients, ASAS 40% by 17/35 (48.6%), while ASAS 5/6 was attained by 15/35 (42.9%). The clinical improvement was associated with the reduction of acute phase reactants as measured by C-reactive protein levels. After the first year of treatment, the "survival rate" of infliximab was 94.3%, after the second year was 91.4%, after the third year was 85.7% and even after 4 years of treatment still maintained high 77.9%. Six (17.1%) patients were withdrawn during the observational period. Three because of lack of efficacy, two because of allergic reactions and one lost from follow-up. Infliximab was effective, safe, and well tolerated in patients with AS. The clinical response was maintained for a period of 4 years and over, with infliximab survival of 77.9%.
