Introduction: N-terminal prohormone of atrial natriuretic peptide ((proANP(1–98)) has been extensively analyzed in patients with chronic renal failure. It has been found to be closely related to the renal function and to interdialytic hydration status. The clinical relevance of proANP(1–98) and cystatin C, a novel marker of glomerular filtration, has not been investigated in the subgroup of critically ill septic patients with no history of chronic renal impairment. Methods: We measured plasma level ofproANP(1–98) and cystatin C in 29 critically ill septic patients on admittance to the surgical intensive care unit and correlated it with the occurrence of acute renal failure. Results: The proANP(1–98) plasma level was significantly higher in the group of patients who developed renal failure (12,722 ± 12,421 vs. 2,801± 2,023 fmol/ml, p < 0.05). Multiple regression analysis shows that proANP(1–98) on the first day in the intensive care unit has a superior predictive value for the occurrence of renal failure to diuresis, calculated creatinine clearance or cystatin C (r = 0.42, p < 0.039). proANP(1–98) is also higher in non-survivors (9,303.8 ± 11,053 vs. 2,448.5 ± 1,803 fmol/ml, p < 0.018). Conclusion: proANP(1–98) is possibly a better predictor of acute renal failure to calculated creatinine clearance or diuresis among critically ill septic patients. Cystatin C was not correlated with occurrence of acute renal failure in this subgroup of patients.
N-terminal pro-atrial natriuretic peptide [proANP(1-98)] has been extensively investigated in patients with chronic heart failure and ishemic heart disease. It is found to be a better marker of cardiac dysfunction than atrial natriuretic peptide (ANP). The possible involvement of proANP(1-98) in cardiac depression caused by sepsis has not been studied yet. Therefore, we analyzed atrial plasma concentration of proANP(1-98) in 17 septic patients with hemodynamic variables measured or calculated using pulmonary artery catheter. The results of altogether 96 measurements show a significant negative correlation of proANP(1-98) and cardiac index (p<0.024), oxygen delivery (p<0.03) and oxygen consumption (p<0.03). There is also a positive correlation with pulmonary vascular resistance (p<0.03). ProANP(1-98) is significantly higher in patients who developed acute respiratory distress syndrome (ARDS) (p<0.001). This study implies that proANP(1-98) is a possible novel hormone marker of cardiac depression caused by sepsis that could be used for prediction of ARDS.
Shunt insertion was the only parameter correlated with cognitive decline on the first day after CEA. Regional anesthesia might offer indirect benefit because of a reduced need of shunting in wakeful patients. Larger studies are required to clarify the role of shunting and type of anesthesia in early neurocognitive deficit after CEA and its impact on the quality of life.
AbstractThe authors presented a case report of the acute abdomen with pelvic abscess because bladder perforation in a 21-year-old patient with multiple sclerosis and intermittent catheterization of the urinary bladder.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
