The aim of this study was to investigate the use of different types of microneedles (MNs) and nanocarriers for in vitro skin permeation and in vivo immunization of plasmid DNA encoding ovalbumin (pOVA). In vitro skin permeation studies indicated that hollow MNs had a superior enhancing effect on skin permeation compared with solid MN patches, electroporation (EP) patches, the combination of MN and EP patches, and untreated skin. Upon using hollow MNs combined with nanocarriers for pOVA delivery, the skin permeation was higher than for the delivery of naked pOVA, as evidenced by the increased amount of pOVA in Franz diffusion cells and immunoglobulin G (IgG) antibody responses...

The purpose of this study was to evaluate the use of different types of microneedles and doses of ovalbumin antigen for in vitro skin permeation and in vivo immunization. In vitro skin permeation experiments and confocal laser scanning microscopy revealed that hollow microneedles had a superior enhancing effect on skin permeation compared with a solid microneedle patch and untreated skin by efficiently delivering ovalbumin-fluorescein conjugate into the deep skin layers. The flux and cumulative amount of ovalbumin-fluorescein conjugate at 8 h after administering with various conditions could be ranked as follows: hollow MN; high dose > medium dose > low dose > MN patch; high dose > medium dose > low dose > untreated skin; high dose > medium dose > low dose > without ovalbumin-fluorescein conjugate...

Proteins and peptides have been used as drugs for almost a century. Technological advances in the past 30 years have enabled the production of pure, stable proteins in vast amounts. In contrast, administration of proteins based on their native active conformation (and thus necessitating the use of subcutaneous injections) has remained solely unchanged. The therapeutic anti-HER2 humanized monoclonal immunoglobulin (IgG) Trastuzumab (Herceptin) is a first line of the treatment for breast cancer. Chicken IgY is a commercially important polyclonal antibody (Ab)...

Allergic rhinitis (AR) is a multifactorial disease characterized by paroxysmal symptoms of sneezing, rhinorrhea, postnasal drip and nasal congestion. For over a century, subcutaneous allergen immunotherapy (SCIT) has been recognized as the most effective therapy to date that may modify the underlying disease course and provide long-term benefits for individuals refractory to pharmacotherapy. However, over the past 25 years, there has been substantial growth in developing alternative therapies to traditional SCIT...

Benralizumab is a humanized, afucosylated, anti-interleukin-5 receptor α, immunoglobulin G (IgG) 1 κ monoclonal antibody. We developed a population pharmacokinetic (PK)/pharmacodynamic (PD) model for benralizumab by analyzing PK and blood eosinophil count data from two healthy volunteer studies (N = 48) and four studies in patients with asthma (N = 152). Benralizumab PK was dose-proportional and adequately described by a two-compartment model with first-order elimination from the central compartment and first-order absorption from the subcutaneous dosing site...

Allergic asthma, caused by inhaled allergens such as house dust mite or grass pollen, is characterized by reversible airway obstruction, associated with an eosinophilic inflammation of the airways, as well as airway hyper responsiveness and remodeling. The inhaled allergens trigger a type-2 inflammatory response with involvement of innate lymphoid cells (ILC2) and Th2 cells, resulting in high production of immunoglobulin E (IgE) antibodies. Consequently, renewed allergen exposure results in a classic allergic response with a distinct early and late phase, both resulting in bronchoconstriction and shortness of breath...

Human immunoglobulin preparations for intravenous or subcutaneous administration are the cornerstone of treatment in patients with primary immunodeficiency diseases affecting the humoral immune system. Intravenous preparations have a number of important uses in the treatment of other diseases in humans as well, some for which acceptable treatment alternatives do not exist. We provide an update of the evidence-based guideline on immunoglobulin therapy, last published in 2006. Given the potential risks and inherent scarcity of human immunoglobulin, careful consideration of its indications and administration is warranted...

Human polyclonal immunoglobulin G (IgG) for therapeutic use has been available for decades. This drug was developed for treatment of antibody deficiency (replacement therapy), although its use has expanded into many anti-inflammatory and immunomodulatory applications in recent years. This review focuses on IgG prescribing for replacement therapy. IgG for replacement is most often administered via the intravenous IgG (IVIG) or subcutaneous IgG (SCIG) routes. IVIG is usually administered every 34 weeks, and SCIG is usually administered weekly, although variations may be considered in all cases...

A 40-year-old male with a long-standing history of type 1 diabetes with end-stage renal failure underwent combined kidney-pancreas (KP) transplant from a standard criteria donor. Post-operative course was uncomplicated with good primary function of both transplant grafts. Induction was with thymoglobulin and maintenance immunosuppression was with tacrolimus, mycophenolate mofetil and prednisolone. Nine weeks post-transplant, the patient developed dysfunction of both grafts. Panel reactive antibody testing revealed that the patient had developed a de novo donor-specific antibody and considering an antibody-mediated rejection the patient was treated with intravenous pulse methyl prednisone 500 mg ×3 doses, IV immunoglobulin 2 mg/kg in two divided doses, and ATG 7 mg/kg (total dose of 700 mg)...
