We describe a unique ABO compatible and 9/10 HLA-matched case of successful allogeneic hematopoietic cell transplantation (HCT) after effective desensitization of a strong anti-HLA-A24 donor-specific antibody (DSA) with mean fluorescence intensity of approximately 18 000. Due to absence of a suitable matched unrelated donor the patient sibling was considered the best available donor, and it was decided to desensitize patient prior to transplant. The strength of HLA-A24 DSA slowly decreased over the course of treatment, necessitating a total of 23 sessions of therapeutic plasma exchange in order to bring the DSA strength to undetectable levels, followed by a successful transplant. In summary, the outcome of this case shows effective application of desensitization treatment to remove strong DSA in HCT patients.

Division of Allergy & Immunology, Department of Medicine, Queen's University, Kingston, ON, Canada.

Drug allergy encompasses a spectrum of immunologically-mediated hypersensitivity reactions (HSRs) with varying mechanisms and clinical presentations. This type of adverse drug reaction (ADR) not only affects patient quality of life, but may also lead to delayed treatment, unnecessary investigations, and increased morbidity and mortality. Given the spectrum of symptoms associated with the condition, diagnosis can be challenging.

Trauma exposure is common in (pre) school-aged children and around one-fifth of exposed children meet the criteria for post-traumatic stress disorder (PTSD). These symptoms can cause severe impairment to a child's functioning and, if left untreated, have negative long-term consequences. Therefore, there is an urgent need for effective treatment to reduce the acute and long-term effects of trauma.

Peanuts are highly nutritious but pose a significant risk of triggering food allergies. While heat treatment can reduce the allergenicity of many foods, it may also alter their structure, potentially impacting detection results. This study employed double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) and lateral flow immunochromatography (LFIA) to evaluate the allergen Ara h 3 following heat-moisture treatment.
