Breakthrough reactions during rapid drug desensitization: Clinical outcome and risk factors

Recently, new diagnostic tools and therapeutic agents have significantly increased the survival rate of cancer patients compared to that in the past. As the number of cancer survivors exposed to multiple courses of chemotherapy increases, more patients become sensitized to chemotherapeutic agents and suffer from hypersensitivity reactions (HSRs).1-3 HSRs to chemotherapeutic agents range from mild cutaneous urticaria to severe reactions, such as life-threatening anaphylaxis, and even death.4 Most HSRs are unpredictable, such that they threaten the safety of patients; moreover, they can be uncontrollable, and severe HSRs limit the effectiveness of chemotherapy, increase hospital costs, and worsen prognosis.

It can be used asynchronously for interpretation of tests (spirometry, skin tests imaging studies), and for communication of information when the simultaneous presence of provider and patient is unnecessary. Synchronous encounters can be either unscheduled and initiated on-demand by patients or they can be facilitated substitutes for in-perso...

ConclusionOur data support the concept of MDH as a distinct and rare subgroup of DH. The prevalence in our database was 2.5% in the total DH alleged patient population and 0.5% of the demonstrated DH. Skin testing and DPT are mandatory for confirming the diagnosis.

In this study, we constructed a dual function nanosystem, copper sulfide nanoplatform loaded with the chemotherapeutic drug docetaxel wrapped by a conjugated polymer-peptide for targeted chemo-phototherapy. The nanoconstruct has been successfully designed with a size of 186.1 ± 5.2 nm, a polydispersity index of 0.18 ± 0.01, and zeta potential of −16.4 ± 0.1 mV. The enhanced uptake and near-infrared-responsive behavior of the nanosystem resulted in efficient drug release, photothermal ablation, effective cytotoxic activity, and potentiated reactive oxygen sp...

Rituximab is a chimeric monoclonal anti-CD20 antibody with wide use in cancer (lymphoma) and connective tissue diseases (rheumatoid arthritis, and vasculitis)1. Hypersensitivity reactions to rituximab can range from type I IgE-mediated reaction (urticaria, shortness of breath, hypotension, or anaphylaxis), to cytokine-mediated reaction (fevers, chills, rigors), or a mix of both, thus limiting the use of rituximab as first line therapy for many cases. Desensitization is a new therapeutic approach which can be performed with rituximab to offset these reactions.
