Diagnostic Evaluation of Hypersensitivity Reactions to Antibiotics in a Large Cohort of Mastocytosis Patients

Diagnostics, 2023
Background: Anaphylactic reactions are a well-known feature of mastocytosis, particularly in relation to hymenoptera venom stings. Although data on the frequency of drug hypersensitivity reactions is limited in mastocytosis, it is hypothesized that these

PD-1 Regulates the Growth of Human Mastocytosis Cells

Allergology International, 2013
Background: Programmed death-1 (PD-1) is a marker for human neoplastic T cells. Here, we evaluated whether or not PD-1 was also a marker for human mastocytosis, and explored the role of PD-1 in human mastocytosis cells.

Mastocytosis – an update [PDF]

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, 2010
SummaryMastocytosis (MC) encompasses a range of disorders characterized by a clonal, pathological accumulation of mast cells having a somatic activating mutation of the tyrosine kinase receptor Kit (exon 17, codon 816; D816V) in more than 90 % of adult patients. The mutation is much less common in children. Skin and bone marrow are most often affected.
