Atypical Bacterial Pathogens and Small-Vessel Leukocytoclastic Vasculitis of the Skin in Children: Systematic Literature Review

“…This systematic review of the literature indicates that also a cutaneous small-vessel vasculitis may occur after an infection caused by the atypical bacterial pathogen Mycoplasma pneumoniae . The clinical picture and the course are similar to those observed in cases preceded by infections such as common cold, tonsillopharyngitis, or otitis media [ 30 , 31 , 32 , 33 , 34 , 35 , 36 ].…”

“…On the other hand, a recent report from China [ 37 ] including 1200 pediatric cases of immunoglobulin A vasculitis found serological evidence for a recent group A Streptococcus infection in 205 (17%) and for a Mycoplasma pneumoniae infection in 58 (4.8%) cases. We do not have any exhaustive explanation for the discrepancy between the Chinese data [ 37 ] and the results of the aforementioned case series [ 30 , 31 , 32 , 33 , 34 , 35 , 36 ]. We speculate that pediatricians customarily do not test for atypical bacterial pathogens in patients with vasculitis, even if preceded by a lower respiratory-tract infection [ 4 ].…”

“…The prevalence of small-vessel vasculitis of the skin accompanying a symptomatic respiratory infection caused by an atypical bacterial pathogen is presently unknown. Seven case series including a total of 1618 patients affected by an immunoglobulin A vasculitis never described this association [ 30 , 31 , 32 , 33 , 34 , 35 , 36 ]. On the other hand, a recent report from China [ 37 ] including 1200 pediatric cases of immunoglobulin A vasculitis found serological evidence for a recent group A Streptococcus infection in 205 (17%) and for a Mycoplasma pneumoniae infection in 58 (4.8%) cases.…”

Hematuria en la niñez: revisión sistemática cualitativa

“…Por su parte, si la hematuria macroscópica es indolora se indica evaluar la relación proteinuria/creatinuria en orina esporádica para determinar una posible vasculitis tipo púrpura de Schönlein-Henoch, puesto que está relacionada con los síndromes nefróticos en su presentación [51].…”
