RESUMO
The systemic reaction to severe trauma and/or infection, acute phase response (APR), are often associated with immunosuppression and reactivation of chronic latent infection. Our main purpose was to verify, in a group of 71 autopsied chronic chagasic with or without APR, the frequency of T. cruzi nests in the central vein of adrenal gland (CVAG). APR, defined by: 1) death secondary to sepsis and/or trauma plus, 2) bleeding stress gastric ulcerations or 3) spleen reactional state or 4) liver steatosis, was observed in 30 chronic chagasic (APR+). Weight, height and body mass index (BMI) were obtained. APR(+) chronic chagasic had worse nutritional status than APR(-) ones: weight = 49.0 vs 54.5 kg; BMI = 17.5 vs 20.6 kg/m2 (median p < 0.05). CVAG T. cruzi nests frequency were similar (43.3 per cent and 43.9 per cent , respectively) between both Groups. We conclude that APR(+) chronic chagasic had worse nutritional status than APR(-) ones, and that APR development did not change the CVAG T. cruzi nests frequency
