Mutaciones en el gen MEFV y evolución clínica en pacientes pediátricos con púrpura de Schönlein-Henoch

“…Los factores infecciosos informados en las publicaciones son el estreptococo betahemolítico del grupo A (GABHS), la bacteria Mycoplasma pneumoniae, el parásito Toxocara canis, la enterobacteria Yersinia, las bacterias Legionella, Helicobacter pylori, enteritis por Campylobacter jejuni, Bartonella henselae, el virus varicela zóster, el virus de la rubéola, los virus de la hepatitis B y A, el virus de Epstein-Barr, el virus del herpes simple (VHS), el citomegalovirus, el virus de la inmunodeficiencia humana y el virus del papiloma humano. [21][22][23][24][25][26] En nuestro estudio, la positividad para hepatitis B se encontró solo en 2 casos con factores virales. En las publicaciones se mencionan factores desencadenantes como las vacunas y las picaduras de insectos; 27,28 en nuestro estudio, un paciente tenía antecedentes de haber sufrido una picadura de abeja.…”

Vasculitis related to viral and other microbial agents

“…The known endothelial tropism of PVB19 has prompted numerous investigations for the potential role of the virus in the pathogenesis of other established vasculitic disorders (Table 1). Through serologic and immunohistochemistry studies as well as DNA amplification in blood, skin, and endothelial tissue samples, human PVB19 infection has been implicated in the pathogenesis of PAN and GPA [126], Behcet's disease [127], and HSP [128,129]. A pathogenetic role for PVB19 has also been implicated in the vasculopathy associated with systemic sclerosis [130], dermatomyositis [131], and systemic lupus erythematosus [132].…”
