RESUMO
Kawasaki disease (KD) has features that appear supporting an infectious cause with a secondary deranged inflammatory/autoimmune response. The association of KD in adults with human immunodeficiency virus infection and the presence of KD in patients with immunodeficiency disorders support the infectious theory. We present four KD patients associated with immunodeficiencies: one with X-linked agammaglobulinemia, one with HIV infection, and two with leukemia; one of these patients also had Down syndrome. We did a literature search to find out all reported cases of immunodeficiency with KD in children. In immunodeficiency disorders, the inability of the immune system to eradicate the pathogens coupled to an exaggerated inflammatory response, especially in chronic granulomatous disease, may lead to the development of KD. The study of patients with immunodeficiencies complicated with KD may shed light into the etiopathogenesis of the disease.

Brucella melitensis is the main cause of human brucellosis worldwide and is considered the most virulent and neurotropic species. In Mexico, this species is considered endemic, being reported since the first decade of the 20th century. Here we present a case of subacute transverse myelitis with the isolation and identification of B. melitensis as the causative agent of Neurobrucellosis in a female patient from the coastal state of Guerrero, Mexico.
