The work demonstrates that after the injection of a heterogenous antigen into rabbits the appearance of antibodies is followed by the "spontaneous" formation of anti-idiotypic antibodies. These anti-antibodies, detected by means of several serological reactions, are specific and have an idiotypic character. Circulating antibody--anti-idiotypic antibody complexes have been detected in the blood of the animals. The injection of autologous anti-idiotypic antibodies into the immunized animals ensures the stimulation of the formation of antibodies and anti-idiotypic antibodies. Immunological memory with respect to anti-idiotypic antibodies develops in the body of the immunized animals.

Background: Sabirnetug (ACU193) is a humanized monoclonal antibody targeting soluble amyloid beta (Aβ) oligomers, which are early contributors to the pathogenesis of Alzheimer's Disease (AD). An ultrasensitive assay was developed to measure sabirnetug pharmacokinetics (PK) in CSF of individuals with early AD in the Phase 1 study INTERCEPT-AD (NCT04931459).
Method: The immunoassay was developed on the Meso Scale Diagnostics (MSD) S-PLEX with improved sensitivity through TURBO-TAG® technology.

Objective: This paper aims to review the efficacy and safety of current chronic urticaria (CU) treatment in children and the existing patient-reported outcome measures (PROMs) used in this age group.
Data Source: Since there are few studies of CU in children, the authors performed a non-systematic review of published articles in English, Spanish, and Portuguese in the PubMed database in the last decade. Keywords used were (antihistamines OR omalizumab OR cyclosporine OR treatment) AND (chronic urticaria) AND (children OR adolescents).

Introduction: Omalizumab, an anti-IgE monoclonal antibody, is effective in treating antihistamine-refractory chronic spontaneous urticaria (CSU). However, tapering strategies for omalizumab are currently not well-studied, and patients may be treated longer than needed. Here, we present the rationale and design of the EXtending Omalizumab Treatment Intervals in patients with Chronic spontaneous urticaria trial, a multicentre, randomised, open-label, non-inferiority clinical trial.

Patients with mast cell activation syndrome (MCAS) can be refractory to standard antimediator therapy. Alternative treatment options to reduce disease burden and improve quality of life are needed. To compile the evidence that supports the use of omalizumab for patients with refractory MCAS.
