Interleukin-10 gene polymorphism (-1082G/A) and allergy to efavirenz in patients infected with human immunodeficiency virus BJID
Rodrigues,Raphael de Oliveira; Carvalho,Paulo Germano de; Arruda,Érico Antônio Gomes de; Rabenhorst,Silvia Helena Barem; Silva,Silvia Fernandes Ribeiro da; Ribeiro,Ilana Farias; Lima,Denise Girão Limaverde; Nagao-Dias,Aparecida Tiemi.
The aim of the present study was to investigate the association between polymorphism in the interleukin-10 gene promoter at position -1082 in human immunodeficiency virus-infected patients who had presented allergic reaction due to efavirenz. The study included 63 patients treated at the Hospital São José de Doenças Infecciosas, Fortaleza, Ceará, Brazil. Twenty-one patients who had presented allergic reaction to efavirenz were compared to 42 patients with no allergic reaction following exposure to this drug. Blood samples were collected for DNA extraction and submitted to the restriction fragment length polymorphism - polymerase chain reaction technique. The -1082AA genotype was significantly more frequent in allergic patients as compared to non-allergic...

Functional changes of dendritic cells in hypersensivity reactions to amoxicillin BJMBR
Lima,C.M.F.; Schroeder,J.T.; Galvão,C.E.S.; Castro,F.M.; Kalil,J.; Adkinson Jr.,N.F..
A better understanding of dendritic cell (DC) involvement in responses to haptenic drugs is needed, because it represents a possible approach to the development of an in vitro test, which could identify patients prone to drug allergies. There are two main DC subsets: plasmacytoid DC (pDC) and myeloid DC (mDC). β-lactams form hapten-carrier conjugates and may provide a suitable model to study DC behavior in drug allergy reactions. It has been demonstrated that drugs interact differently with DC in drug allergic and non-allergic patients, but there are no studies regarding these subsets. Our aim was to assess the functional changes of mDC and pDC harvested from an amoxicillin-hypersensitive 32-year-old woman who experienced a severe maculopapular exanthema...
