Despite correlative evidence for a role for tumor necrosis factor-alpha in the pathogenesis of COPD, the anti-tumor necrosis factor-alpha, infliximab did not show clinical effectiveness inside a double-blind, placebo-controlled, phase II medical trial. This study sought to evaluate the systemic inflammatory profile associated with COPD and to assess the effect of tumor necrosis element neutralization on systemic swelling. Methods Serum samples (n = 234) from your phase II trial were collected at baseline and after 24 weeks of placebo or infliximab. Additionally, baseline serum samples were from an independent COPD cohort (n = 160) and 2 healthy control cohorts (n = 50; n = 109). Serum concentrations of a broad panel of inflammation-associated analytes were measured using a 92-analyte multiplex assay. Results Twenty-five proteins were significantly elevated and 2 were decreased in COPD, including highly elevated CD40 ligand, brain-derived neurotrophic element, epidermal growth element, acute-phase proteins, and neutrophil-associated proteins. This profile was mainly self-employed of smoking status, age, and medical phenotype. The majority of these associations of serum analytes with COPD are novel findings. Improved serum creatine kinase-muscle/mind and myoglobin correlated modestly with decreased pressured expiratory volume at 1 second, suggesting cardiac involvement. Infliximab did not impact this systemic inflammatory profile. Conclusions A strong systemic inflammatory profile was associated with COPD. This profile was generally TMB-PS self-employed of disease severity. Because anti-tumor necrosis factor-alpha did not influence systemic swelling, how to control the underlying pathology beyond sign suppression remains unclear.

In addition to symptoms related to airway pathology–including cough, excessive sputum, and dyspnea–COPD offers systemic manifestations, one of which may be exercise limitation related to muscle mass weakness [1]. Systemic swelling has been explained in COPD, including improved production of the potent inflammatory mediator tumor TMB-PS necrosis element (TNF)-alpha [2-5]. Improved TNF-alpha production has also been associated with muscle mass loss and weakness in COPD [5-7]. Although no natural animal models of COPD exist, intraperitoneal injection of TNF-alpha in rats prospects to emphysema,[8] which may resemble the apoptosis of alveolar cells observed in COPD individuals with emphysema [9,10]. Because TNF-alpha inhibitors have demonstrated clinical effectiveness in various chronic inflammatory disorders,[11-13] a phase II, double-blind, multicenter, placebo-controlled medical study was performed to evaluate the security and effectiveness of infliximab (Janssen Biotech, Inc., Horsham, PA, USA), an anti-TNF-alpha monoclonal antibody, in the treatment of COPD [14]. Infliximab failed to demonstrate improvement in the primary endpoint, the Chronic Respiratory Questionnaire (CRQ) score, and in additional secondary clinical results after 24 weeks of treatment. Serum samples were from individuals at baseline and after 24 weeks of treatment. The goal of this study was to test the hypothesis that the lack of medical efficacy of infliximab in COPD individuals was associated with a failure of infliximab to significantly impact the underlying systemic inflammation associated with COPD. From earlier pharmacodynamic studies of infliximab, several serum biomarkers, including MIP-1beta and TNF-RII, were shown to be significantly decreased by anti-TNF treatment, with changes in these biomarkers correlating with medical efficacy [15]. In addition, the general systemic inflammatory and biochemical profile associated with COPD was defined and evaluated for whether infliximab treatment could effect this broader.
