Amiodarone-Induced Lung Injury With Bilateral Lung Pneumonitis and Peripheral Eosinophilia.

Amiodarone is a widely used antiarrhythmic that is used in the management of a variety of atrial and ventricular arrhythmias. Amiodarone-induced lung injury is an adverse effect in 5% of patients taking amiodarone, usually within 12 months of commencing therapy. Different mechanisms of injury and histopathological changes have been proposed and described.

Efficacy of extracorporeal photopheresis in clearance of antibodies to donor-specific and lung-specific antigens in lung transplant recipients.

Background: Extracorporeal photopheresis (ECP) has been used to treat chronic rejection after lung transplantation (LTx). We investigated the effect of ECP on several immune parameters that have been associated with poor lung function, including donor-specific antibodies (DSA) to human leukocyte antigen (HLA), antibodies against the lung-associated self-antigens (SAg), Kα1-tubulin (Kα1T), collagen I and V, and circulating levels of pro-inflammatory and anti-inflammatory cytokines.

Methods: Sera were collected from post-LTx patients diagnosed with bronchiolitis obliterans before and 6 months after initiation of ECP.

Pre-transplant antibodies to Kα1 tubulin and collagen-V in lung transplantation: clinical correlations.

Background: Immune responses to lung-associated self-antigens (SAgs) have been implicated in chronic lung allograft rejection. The goals of this study were to determine the prevalence of pre-existing antibodies (Abs) to the SAgs in pulmonary diseases and the association between pre-existing Abs to SAgs and the development of primary graft dysfunction (PGD), donor-specific antibodies (DSA), and chronic rejection.

Methods: Pre- and post-transplant sera were analyzed from 317 lung transplant (LTx) recipients between 2000 and 2011 with diagnosis of chronic obstructive disease (n = 161), idiopathic pulmonary fibrosis (IPF; n = 50), cystic fibrosis (CF; n = 55), and others (n = 51).

Characterization of the cellular uptake and metabolic conversion of acetylated N-acetylmannosamine (ManNAc) analogues to sialic acids.

"Sialic acid engineering" refers to the strategy where cell surface carbohydrates are modified by the biosynthetic incorporation of metabolic intermediates, such as non-natural N-acetylmannosamine (ManNAc) analogues, into cellular glycoconjugates. While this technology has promising research, biomedical, and biotechnological applications due to its ability to endow the cell surface with novel physical and chemical properties, its adoption on a large scale is hindered by the inefficient metabolic utilization of ManNAc analogues. We address this limitation by proposing the use of acetylated ManNAc analogues for sialic acid engineering applications.
