Case Reports: Case Report

We present 2 cases of patients with septic shock and discuss changes in B-type natriuretic peptide (BNP) levels. While previous increases in BNP in septic shock were attributed to the accompanying myocardial depression, recent work claims that high levels of BNP in sepsis are related to an alteration in the BNP clearance pathway. We postulate from these cases that increased BNP should not automatically be associated with cardiac dysfunction and may assist in an early, difficult diagnosis of septic shock.
