The Patent Blue V Paradox: Hidden Offender, Serial Culprit.
Dermatitis
January 2025
From the Department of Allergy and Clinical Immunology, Unidade Local de Saúde de São João, Porto, Portugal.
Patent Blue V (PBV) is extensively used in sentinel lymph node identification in cancer surgery, potentially leading to an increased incidence of hypersensitivity reactions. A retrospective analysis was conducted on patients with suspected PBV hypersensitivity, at our center from 2010 to 2023. Skin prick tests (SPT) were performed on all patients, followed by intradermal tests (IDT) if SPT was negative.

Detecting β-lactoglobulin (β-Lg) with high sensitivity and selectivity is an urgent requirement due to nearly 80% of milk anaphylaxis, such as respiratory tract, skin urticaria, and gastrointestinal disorders, being caused by β-Lg. An ultrasensitive β-Lg electrochemical aptasensor utilizing core-satellite gold nanoparticle@silver nanocluster (AuNPs@AgNCs) nanohybrids as electrocatalysts was developed. First, β-Lg aptamer was anchored on gold electrodes and AuNPs to obtain high selectivity.

Kounis syndrome also known as allergic myocardial infarction, represents the simultaneous occurrence of acute coronary syndromes with allergic or hypersensitivity reactions. We present a case of a 58-years-old male who developed anaphylaxis following a leech bite, leading to myocardial infarction despite the absence of prior allergic history. He was entubated and cardiopulmonary resusciation had been performed for 10 minutes.

Two-pore channels (TPCs) are adenine nucleotide and phosphoinositide regulated cation channels. NAADP activates and ATP blocks TPCs, while the endolysosomal phosphoinositide PI(3,5)P activates TPCs. TPCs are ubiquitously expressed including expression in the innate as well as the adaptive immune system.

Vaccination is a fundamental principle of preventive health care. Administration of the vaccine, which contains the antigen(s) of a pathogen, activates the immune system and provides protection against infection. The immunogenicity and allergenicity of a vaccine may lead to various adverse reactions, depending on the responsiveness and susceptibility of the vaccinated individual.
