Alterações hematológicas na leptospirose

Abstract: Foram estudadas as alterações hematológicas de 30 pacientes com diagnóstico de leptospirose internados na Clínica de Doenças Infecciosas e Parasitárias do Hospital das Clínicas da Faculdade de Medicina da Universidade de Sáo Paulo. Verificou-se que mais da metade dos pacientes 16 (53,3%) apresentavam contagem normal de leucócitos no momento da internação; 12 (40%) apresentavam leucócitos e 2 (6,6%) leucopenia. Vinte e cinco doentes (83,3%) apresentavam desvio à esquerda e 29 (96,6%) neutrofilia relativa. Vinte… Show more

“…This seems to be the part of coagulation most affected in the severe forms of leptospirosis. Such findings are in accordance with those observed by several authors 7,15,[19][20][21][22][23] . NICODEMO et al 22 observed that thrombocytopenia in leptospirosis seems to be determined by activation, adhesion and aggregation of platelets to the stimulated vascular endothelium by the action of endotoxin or other bacterial products.…”

“…From the pathology point of view, in addition to specific tissue lesions, like interstitial nephritis and hepatic central-lobular necrosis, a generalized vasculitis accompanied by hemorrhagic phenomena is seen in all tissues (24,29). Few spirochetes can be observed on the damaged tissue, strongly suggesting a toxic nature of the disease process (3).…”

“…Tissue lesions are characterized by the occurrence of major cellular damage in the presence of few microorganisms, suggesting the involvement of toxic factors from either the spirochete or the host, associated with bacterial-cellular adherence phenomena (5,15,29). Cytotoxic activity of Leptospira interrogans cellular components was demonstrated in the past (10,32).…”
